Differentiated collecting station for used plastic containers with suction drawing

Abstract

 The collection station essentially consists of an ideally cylindrical or parallelepiped compact mass body forming the collecting chamber for used plastic material containers and is equipped in different ways with a suction duct. The device can be directly laid on the ground and its emptying is nearly instantaneous by means of an aspiration air flux at high speed coming from a suction element, acting with automatic hooking, of a mobile drawing compartment which then transforms the above mentioned containers in recovered product for recycl­ing. In a version a station is foreseen which, on a base (1) leaning on the ground, uses a parallelepiped containment body (2) with loading mouths (3) and an inspection door (4). The plastic containers, or heterogenous plastic material, which have been let in, reach the bottom of the chamber (5) gliding on an inclined plane (6) and are stopped by a wall (7) with an inclination opposed to the preceding plane (6). On this site a suction duct (9), with catching mouth (8), is fitted with check and directional control valves (11). By means of the said suction duct (9) the containers are then taken away by means of a mobile operative compartment (17).

Description

[0001] The invention refers to a differentiated collecting station of containers in plastic materials and/or used heterogenous plastic, and which essentially consists of a containment body forming a compact mass determining a collecting chamber equipped with a suction duct or with a side sucking mouth. The said station, which can be set on the ground, can be used without supporting means and without the presence of a staff on the ground for discharging operations. What preceedes is possible because the collecting chamber can be emptied nearly at once by means of a suction air flux at high speed through a suction element of a mobile drawing element. Moreover, no staff is required on the ground since the above suction element is foreseen to be fitted, by means of an automatic coupling, in the drawing opening properly equipped with check directional control valves. The invention device is foreseen to compose a defferentiated collection network of used plastic material containers and/or heterogenous used plastic, in which network drawing is periodically carried out by a mobile operative compartment which transforms said material into a recovered one to be recycled.

[0002] In particular, the device can be used on the road and in feul distributing stations. Separately, the above station allows the conversion of the containers charged in the collect­ing chamber by gravitationally passing through a perforated metal - or other filter medium - which constitutes the conver­sion form of the continers charged into the collecting chamber, and to recover the liquid still present in the used containers, such as for instance lubricating oils.

[0003] The present collecting stations carry out mechanical emptying and operate with a hopper or by topple of the store body. This conventional methodology determines and operational complex consisting of three components: one warehause, a structure to support it and means of general kind for unloading. Consequently, particular costs and encumbrance of these devices are the result which must be further controlled by the staff on the ground. These disadvantages do not allow to use this assembly in the nets for collecting used containers in plastic materials at the origins. In comparison which the present collecting stations, the invention system mainly offers the following advantages: 1) nearly instantaneous emptying even without staff on the ground; 2) structural simplification since the station conformation theorically coincides with a parallelopiped or cylindrical containment shape which forms the collecting chamber performed in advance without linkages thus carrying out a considerable reduction of the production costs; 3) a compact mass station is performed which shows a highly reduced encumbrance, since there is no supporting structure, as well as mechanical agibility; 4) it allows to recover the liquids remained in the containers which have put in. Furthermore, essentially important is the circumstance that the station emptying operations do not interfere in any way with the activity of the staff using the collection station, a condition of particular importance for the fuel station staff.

[0004] In a version the containing body of the compact mass has been foreseen with the ideally parallelepiped structure 2 on plate 1 on the ground and forming the containment chamber into which the containers are introduced through side charging doors 3. For interventions in the collecting room, if required, an upper inspection door 4 has been foreseen. The introduced container reaches the bottom of the collecting tank 5 by slipping on the tilting perforated metal 6 and stops against the wall 7 having an opposed inclination in order to form with the said perforated metal 6, a total drawing point for the containers which are subsequently charged in. On the above named drawing seat, picking up opening 8 is foreseen with suction duct 9 fitted with a drawing duct 10 and check directional control valve 11. Alternatively, in order to increase the suction effect a conveyer 12 is foreseen to let into the picking up mouth 10.

[0005] Execution versions of the above mentioned devices are illustrat­ed in the drawings of table 1. With reference to this table, fig. 1 is the side view of a station in parallelepiped shape. Fig. 2 is the section view of the same collecting station as per fig. 1 to show the inside conveying system on a tilting perforated metal 6 which lets the containers reach the wall 7. In this position, the containers are sucked through the picking up opening 8 into duct 9. Furthermore through the perforated metal plane 6, the liquid remained in the used containers pass as a charge into the lower small tank 13 of chamber 14. For checking the flux, the adjustable regulator 15 has been foreseen which can be fitted on door 16. A schematic view of the emptying system for a collecting station, according to the version with sucking duct fitted outside the collecting chamber, can be observed in fig. 5. With reference to this last figure, the mobile operative drawing compartment 17, on line 18, empties the ground station by means of the suction element 19 inserted in the drawing mouth 10.

[0006] In another version, a station is foreseen with sucking duct built in the collecting chamber. This version uses a containment body consisting of an intermediate cylindrical part 20 fitted between an upper covering part 21 and a lower hopper shaped part 22. Centrally, in a suspended position in the collecting chamber 23, the suction duct 24 is foreseen which is firmly held by a radial system consisting of three chases 25 with an adjustable lower pick up opening 26 to regulate the power and/or the tilting of the air flux according to the requirements and a higher drawing mouth 27 to be precluded by means of a check and directional control door 28. The used containers are put into the opening 29, slide towards the perforated metal 30 and reach the hopper shaped drawing seats, while the liquids therein contained drip downwards. In a version, the picking up opening 26 can be regulated in its depth through a telescope means.

[0007] An execution version of the above named devices is illustrated in the drawings of table 2. With reference to this table, fig. 6 is the section view of the station to point out the particular position of the suction duct and the ones of the boltes handhole 32, of the inspection fixed light 33 and of the adjustable ventilation handhole 34. Fig. 7 is the side view of the same station to point out a hypothetic contain­er in sucking position on the bottom in perforated metal plane 30. Fig. 8 is the station view from above to allow to note the covering upper part 21 fitted with four loading openings 29. Fig. 9 is the lower view of the same station to point out its flat base structure 35 which, with the raised outer structure 36, determinates the parallelepipe-shaped base with rounded corners foreseen for the device containment. Furthermore, the removable part 37 containing the recovery oils, as well as the possible picking-up openings 38, can be seen.The emptying system of a collecting station, according to the version with a sucking duct built in the collecting chamber, can be noted in a schematic view in fig. 10. With reference to this last one, the same mobile operative catching compartment 17 empties the ground station on line 18 by means of the sucking element 19 fitted in the drawing mouth 27.

[0008] In the executions, the stations can be carried out in different ways and properly equipped according to the different require­ments.
