Description

Technical Field

[0001] This utility model relates to the field of solid waste cleaning technology, and in particular to a pre-cleaning device for whole plastic bottles. Background Technology

[0002] With the development of technology, the processing volume of plastic bottles has gradually increased. As the processing volume increases, the crushing process needs to work continuously. However, the mud and impurities on the surface of the plastic bottles can damage the crusher blades, preventing the crusher from processing more efficiently. Therefore, the mud and impurities on the surface of the plastic bottles need to be removed before they enter the crusher.

[0003] Existing technologies often involve cleaning plastic bottles by placing them in a water tank. However, the bottle caps are not removed, making it difficult to fill with water or only a small amount. Due to the presence of some air inside the bottle and the large contact area between the plastic bottle and the water surface, the plastic bottle may float on the surface or be half-floating and half-sinking, resulting in incomplete cleaning and leaving the surface still carrying mud and sand.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, such as welding, riveting, or bonding; it can also be a detachable connection, such as threaded connection, keyed connection, or pin connection; or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] like Figure 1-4 As shown, the present invention proposes a pre-cleaning device for plastic bottles, including a cleaning tank 1 with an opening at the top and a cover plate 2 on it. The cover plate 2 has a feed inlet, and the bottom of the cleaning tank 1 has a discharge component. The cleaning tank 1 contains a filter component, and two agitating components are spaced apart inside the cleaning tank 1, both located above the filter component. One end of the cleaning tank 1 has a scooping port, and a scooping component is located at the scooping port. The agitating components can drive the plastic bottle to move to the scooping port.

[0025] This technical solution solves the problem of incomplete cleaning of plastic bottles by setting up an agitation component and a filtration component. The agitation component makes the plastic bottles roll and rub in the water to remove surface sludge and impurities, and can also thoroughly clean plastic bottles that are partially floating on the water. The filtration component can intercept and separate impurities and can block plastic bottles filled with water, thereby effectively preventing plastic bottles from sinking to the bottom wall of the cleaning tank 1 due to being full of water, which would affect the discharge operation of the discharge component. This solution can effectively improve the cleaning effect of plastic bottles, provide clean raw materials for subsequent crushing processes, and avoid impurities damaging the crusher blades.

[0026] Furthermore, this application also proposes that the agitation assembly includes a first main shaft 3, two first main shafts 3 are spaced apart in the cleaning tank 1 and are rotatably arranged with their inner walls, the outer end of the cleaning tank 1 is provided with two first motors 5 corresponding to the two first main shafts 3, the cleaning tank 1 is provided with a first through hole for the first main shafts 3 to pass through, the first main shafts 3 pass through the first through hole and are coaxially connected with the output shaft of the first motors 5, and a plurality of blades 4 are detachably provided on the first main shaft 3, the plurality of blades 4 being spirally arranged.

[0027] Specifically, the first main shaft 3 is rotatably connected to the inner wall of the cleaning tank 1 via bearings, wherein the bearings are waterproof deep groove ball bearings. The first motor 5 is fixed to the outer wall of the cleaning tank 1 via a flange, and the motor output shaft is coaxially driven with the first main shaft 3 via a coupling. This technical solution achieves directional movement of plastic bottles within the cleaning tank 1 through the design of dual-shaft helical blades 4. When the first motor 5 drives the first main shaft 3 to rotate, the helical blades 4 generate axial thrust, pushing the plastic bottles from the inlet to the outlet. The parallel arrangement of the two shafts forms staggered stirring zones, preventing the plastic bottles from accumulating. The detachable design of the blades 4 facilitates maintenance and replacement, and the blades 4 also cause the plastic bottles to tumble during rotation, thereby cleaning the plastic bottles that are partially floating on the water surface.

[0028] Furthermore, this application also proposes a mounting plate 6, bolts and nuts, wherein a plurality of mounting plates 6 are spirally provided on the first main shaft 3, the mounting plates 6 are provided with a second through hole, the blade 4 is provided with a third through hole communicating with the second through hole, the blade 4 is fitted with the mounting plate 6, one end of the bolt passes through the second through hole and the third through hole in sequence, the nut is threaded on the bolt, and the nut can be moved to abut against the blade 4.

[0029] This technical solution enables the detachable installation of blades 4 through the cooperation of mounting plate 6, bolts and nuts, which facilitates the adjustment of the number of blades 4 or the replacement of damaged blades 4 according to actual needs.

[0030] Furthermore, this application also proposes that the filter assembly includes two U-shaped filters 7, which are arranged side by side and detachably connected to the inner wall of the cleaning tank 1, with the U-shaped filters 7 located below the first main shaft 3.

[0031] Therefore, by setting up a U-shaped filter screen 7 structure, this technical solution can fit the first main shaft 3 and the blades 4 more closely, thereby effectively preventing the plastic bottles that sink in water from staying on the filter screen. The blades 4 cannot drive the filter screen when rotating, thus improving the stability of the device during operation.

[0032] Furthermore, this application also proposes a system including two first mounting strips 8 and two second mounting strips 9. The two first mounting strips 8 are respectively connected to the inner walls of both ends of the cleaning tank 1. Each of the two first mounting strips 8 is provided with a plurality of first threaded blind holes at intervals. The two second mounting strips 9 are fitted together and located between the two first mounting strips 8. The two ends of the second mounting strips 9 are respectively connected to the inner walls of both sides of the cleaning tank 1. The second mounting strips 9 are provided with second threaded blind holes. The upper ends of the U-shaped filter screen 7 are provided with connecting plates 10 on both sides. Each connecting plate 10 is provided with a plurality of fourth through holes. The two connecting plates 10 are respectively placed on the first mounting strips 8 and the second mounting strips 9. The fourth through holes are respectively connected to the corresponding first threaded blind holes or second threaded blind holes. Screws pass through the fourth through holes and extend into the first threaded blind holes or second threaded blind holes. The plurality of screws are respectively threadedly connected to the first mounting strips 8 or the second mounting strips 9. The plurality of screws abut against the connecting plates 10 respectively.

[0033] In response, this technical solution achieves rapid disassembly and maintenance of the U-shaped filter screen 7 by setting up a layered installation structure. The first mounting strip 8 and the second mounting strip 9 form a stable support frame. The screw connection between the connecting plate 10 and the first mounting strip 8 and the second mounting strip 9 ensures the firmness of the filter screen installation. Compared with the existing technology, this structure solves the problem of incomplete cleaning caused by the difficulty of disassembling the filter screen and improves the equipment maintenance efficiency.

[0034] Furthermore, this application also proposes that the discharge assembly includes a discharge trough 11, the bottom end of the cleaning tank 1 is provided with a discharge port, the discharge trough 11 is located inside the discharge port and is sealed to its inner wall, the inner walls at both ends of the cleaning tank 1 are inclined towards the discharge trough 11 from top to bottom, the discharge trough 11 is provided with a conveying auger 12, the bottom end of the discharge trough 11 is provided with a discharge opening, and a valve is provided at the discharge opening.

[0035] Therefore, this technical solution effectively solves the problem of poor sediment discharge during the washing of plastic bottles by using the inclined inner wall of the washing tank 1 and the cooperation of the conveying auger 12. The inclined inner wall causes the sediment to automatically collect in the discharge tank 11 under the action of gravity, while the rotation of the conveying auger 12 continuously transports the sediment to the discharge opening.

[0036] Furthermore, this application also proposes that the material scooping assembly includes a discharge hopper 13, which is located at the scooping port and connected to its inner wall. A second main shaft 14 is rotatably provided inside the discharge hopper 13. A plurality of scooping rods 15 are evenly distributed on the outer circumference of the second main shaft 14. The scooping rods 15 can rotate with the second main shaft 14 and extend into the cleaning tank 1. A second motor 16 is provided on the outer circumference of the discharge hopper 13. A second opening is provided on the discharge hopper 13 for the second main shaft 14 to pass through. The second main shaft 14 passes through the second opening and is coaxially connected to the output shaft of the second motor 16.

[0037] This technical solution uses a rotating scooping rod 15 to continuously push the plastic bottles floating on the water surface toward the scooping port, solving the problem that plastic bottles are difficult to collect effectively due to buoyancy in the traditional cleaning tank 1. When the stirring component pushes the plastic bottles to the scooping port area, the rotating scooping rod 15 can overcome the surface tension of the water and force the semi-floating plastic bottles into the discharge hopper 13. This mechanical scooping mechanism realizes automated continuous operation.

[0038] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope.
