Description

Technical Field

[0001] The invention relates to the technical field of plastic recycling and cleaning, and in particular to a cleaning device and a drying system for plastic products. Background Art

[0002] In the recycling process of plastic products, the plastic needs to be crushed and then hot-melt recycled. Since there is a lot of dirt adhering to the waste plastic, it needs to be cleaned before recycling to improve the quality of the recycled plastic.

[0003] When cleaning existing plastic products, after the conveyor is sent into the cleaning tank, the plastic is stirred and cleaned by the stirring member in the cleaning tank. During the cleaning process, some impurities will float above the cleaning tank. These impurities mainly come from the dirt carried by the waste plastic itself. The floating impurities may re-attach to the surface of the plastic being cleaned, resulting in incomplete cleaning, affecting the cleanliness of the plastic and the subsequent processing quality. When the cleaning work is frequent, the accumulation rate of floating objects will also increase, which will cause the replacement of the cleaning liquid to become more frequent. Because each time the cleaning liquid is replaced, the plastic cannot be cleaned again, so the efficiency of plastic cleaning is affected. At the same time, frequent replacement of the cleaning liquid also leads to an increase in the cost of using the cleaning liquid, which cannot meet people's needs.

[0004] Therefore, a cleaning device and a drying system for plastic products are proposed to solve the above problems. Summary of the invention

[0014] As a preferred embodiment, a drying system for plastic products comprises the following steps:

[0016] Step 2: Drying of plastic products;

[0017] The step 1 comprises: firstly, sending the plastic products into the cleaning tank body for cleaning, and stirring the plastic products by the stirring shaft and the wave hole plate during cleaning, and the cleaning time is 3 to 10 minutes, and then, the cleaned plastic products are transported to the drying equipment, and the temperature is gradually increased to preheat the cleaned plastic products;

[0018] The step 2 comprises: placing the plastic product preheated in step 1 into a drying device.

The drying temperature is 60 to 80° C. and the drying time is 20 to 60 minutes, and finally the drying of the plastic product is completed.

[0019] Compared with the prior art, the present invention provides a cleaning device and drying system for plastic products, which have the following beneficial effects:

[0020] 1. The buoyancy can drive the floating block and the sliding tube to slide continuously at the bottom of the liquid inlet pipe, so that the suction head can adapt to the liquid surface at different heights, thereby improving the adaptability of extracting the cleaning liquid. When the circulating filter mechanism is used, when the cleaning liquid passes through the T-tube and the filter plate, the circulating cleaning liquid can be filtered by the blocking of the filter plate. The impurity particles floating on the surface of the cleaning liquid can be filtered by the filter plate, thereby avoiding the situation that the floating impurities may re-attach to the plastic surface being cleaned. At the same time, the saturation speed of the cleaning liquid is also reduced, thereby reducing the replacement frequency of the cleaning liquid, saving costs, and improving the efficiency of the cleaning work. At the same time, through the sliding arrangement of the floating block, the suction head, the sliding tube and the liquid inlet pipe, the buoyancy of the cleaning liquid can make the floating block always float on the surface of the cleaning liquid, thereby enabling the suction head to continuously extract the cleaning liquid on the upper surface of the cleaning tank body, thereby completely removing the floating objects in the cleaning liquid.

[0021] 2. Through the setting of the stirring and toggling mechanism, with the cooperation of the convex block, the wave hole plate can continuously toggle the cleaning liquid and the plastic parts up and down, which increases the contact frequency and strength between the cleaning liquid and the plastic parts, and also promotes the circulation of the cleaning liquid in the container, so that the cleaning liquid can more evenly penetrate into every corner and gap of the plastic parts, thereby effectively removing stains and impurities, improving the cleaning quality, and re-discharging into the cleaning tank body through the drain pipe to complete the circulation of the cleaning liquid in the cleaning tank body. When the cleaning liquid is discharged through the drain pipe, the impact of the cleaning liquid can also push the plastic parts to roll. During the circulation process, the cleaning liquid constantly contacts the surface of the plastic parts, which helps to further disintegrate and remove stubborn stains and improve the cleaning effect;

[0022] 3. By setting up the filter replacement mechanism, the replacement and cleaning process of the filter disc is continuous and can be completed without closing the T-tube, so that work and replacement can be carried out simultaneously, further improving the cleaning efficiency of plastic parts. At the same time, through simple sliding, the clamping of multiple L-shaped clamping rods and clamping holes, and the insertion and limiting of arc-shaped inserts and arc-shaped slots can be achieved. Compared with the bolt fixing in the prior art, it does not require the use of tools and the rotation operation of multiple bolts. Not only is the replacement process more convenient, but also the fixing effect of the sliding insert is guaranteed by fixing and limiting the multiple sides of the sliding insert, thereby ensuring the stability of the filter disc during filtering.

The lower end of the sliding pipe 403 is fixedly connected with a suction head 404, and both sides of the suction head 404 are symmetrically fixedly connected with floating blocks 40 5. A piston 406 is slidably connected to the inner surface of one end of the T-shaped tube 401, and a sliding rod 407 is fixedly connected to one end of the piston 406.

[0048] Embodiment 2

[0049] The drying system of plastic products includes the following steps:

[0050] Step 1: Preparation and preheating of plastic products;

[0051] Step 2: Drying of plastic products;

[0052] Step 1 includes: first, the plastic products are sent into the cleaning tank 1 for cleaning, and the plastic products are moved by the stirring shaft 2 and the wave hole plate 301 during cleaning, and the cleaning time is 3 to 10 minutes, and then the cleaned plastic products are sent to the drying equipment, and the temperature is gradually increased to preheat the cleaned plastic products;

[0053] Step 2 includes: placing the plastic product preheated in step 1 into a drying device. At this stage, the temperature of the drying device is kept stable and ventilation is performed to accelerate the evaporation of moisture on the surface of the plastic product. The drying temperature is 60 to 80°C and the drying time is 20 to 60 minutes, and finally the drying of the plastic product is completed.

[0054] Everything in the above example works like this:

[0055] In the initial state: one end of the stirring shaft 2 can be fixedly connected to the external driving motor, and the wave hole plate 301 is in contact with the inner wall of the bottom of the cleaning tank body 1. At this time, the space between the top of the inner wall of the sliding frame 302 and the stirring shaft 2 is small, and under the action of the floating block 405, the suction head 404 and the floating block 405 are located on the upper surface of the cleaning liquid in the cleaning tank body 1, and one of the filter plates 502 on the sliding plug plate 501 is located inside the T-shaped tube 401. When the reset spring 506 is in a normal state, the arc-shaped insert 509 is plugged into the arc-shaped slot 503, and the L-shaped clamping rod 512 is clamped into the clamping hole 504.

[0056] The following is the working process of the stirring and moving mechanism for moving the plastic parts at the bottom of the cleaning tank body 1 and the circulating and filtering mechanism for sucking and circulating the cleaning liquid in the cleaning tank body 1:

[0057] When the plastic parts are poured into the cleaning tank body 1 for cleaning, the external drive motor is started, and the output end of the drive motor rotates to drive the stirring shaft 2 to rotate at the same time and stir and clean the cleaning liquid and the plastic parts in the cleaning tank body 1. When the stirring shaft 2 rotates, the stirring shaft 2 also drives the protrusion 303 to rotate, so that when the protrusion 303 rotates to the top of the stirring shaft 2, the round surface of the protrusion 303 approaches and squeezes the arc surface at the top of the sliding frame 302, thereby driving the sliding frame 302 and the wave hole plate 301 to move upward, and when the protrusion 303 moves away, the wave hole plate 301 can be affected by gravity and the counterweight block and automatically fall down, so that with the cooperation of the protrusion 303, the wave hole plate 301 can not move the cleaning liquid and the plastic parts up and down, thereby increasing the contact frequency and strength between the cleaning liquid and the plastic parts, and promoting the circulation of the cleaning liquid in the container, so that the cleaning liquid can more evenly penetrate into every corner and gap of the plastic parts, thereby effectively removing stains and impurities and improving the cleaning quality;

[0058] Furthermore, when the stirring shaft 2 rotates, the driving gear 408 is driven to rotate at the same time. Due to the meshing arrangement of the driven gear 409 and the driving gear 408, the driven gear 409 and the fixed disk 410 can be driven to rotate at the same time. When the fixed disk 410 rotates, the eccentric block 411 is eccentrically arranged, and the eccentric block 411 makes an arc motion and pulls or pushes the linkage rod 412, thereby pulling or pushing the sliding rod 407 and the piston 406 to slide on the inner surface of one end of the T-shaped tube 401 through the linkage rod 412. Through the cooperation of the one-way liquid inlet valve and the one-way liquid outlet valve, when the piston 406 approaches the fixed disk 410, the T-shaped tube 401 can be made to move. 1 generates negative pressure, and the cleaning liquid in the cleaning tank body 1 can be sucked into the T-shaped tube 401 through the liquid inlet pipe 402, the sliding pipe 403 and the suction head 404. When the piston 406 moves in the direction away from the fixed plate 410, the liquid in the T-shaped tube 401 can be pushed into the discharge pipe 413, and then discharged into the cleaning tank body 1 again through the discharge pipe 413, completing the circulation of the cleaning liquid in the cleaning tank body 1. When the cleaning liquid is discharged through the discharge pipe 41, the impact of the cleaning liquid can also push the plastic parts to roll. During the circulation process, the cleaning liquid constantly contacts the surface of the plastic parts, which helps to further disintegrate and remove stubborn stains and improve the cleaning effect.

[0059] In addition, the sliding arrangement of the floating block 405, the suction head 404, the sliding tube 403 and the liquid inlet pipe 402 can make the floating block 405 always float on the surface of the cleaning liquid through the buoyancy of the cleaning liquid, so that the suction head 404 can continuously extract the cleaning liquid on the upper surface of the cleaning tank body 1, so that the floating objects in the cleaning liquid can be extracted together. At the same time, the floating block 405 and the sliding tube 403 can be driven to slide continuously at the bottom of the liquid inlet pipe 402 through the influence of buoyancy, so that the suction head 404 can adapt to liquid levels of different heights, thereby improving the adaptability when extracting the cleaning liquid;

[0060] Please refer to the above working process Figures 1 to 7 .

[0061] The following is the working process of the filter replacement mechanism for filtering the cleaning liquid in the cleaning tank body 1:

[0062] Furthermore, when the circulating filter mechanism is used, when the cleaning liquid passes through the T-shaped tube 401 and the filter plate 502, the circulating cleaning liquid can be filtered by the blocking of the filter plate 502, and the impurity particles floating on the surface of the cleaning liquid can be filtered by the filter plate 502, thereby preventing the floating impurities from reattaching to the surface of the plastic being cleaned, and at the same time reducing the saturation speed of the cleaning liquid, thereby reducing the replacement frequency of the cleaning liquid, saving costs, and improving the efficiency of the cleaning work;

[0063] When the filter disc 502 in the T-tube 401 has been used for a long time and the filtering effect has deteriorated, the sliding ring 507 can be slid upward, the return spring 506 is compressed, and the slider 508 and the arc plug 509 are driven to slide upward, so that the arc plug 509 is disengaged from the plug-in limit of the arc slot 503. At the same time, when the sliding ring 507 slides upward, the lower end of the rotating connecting rod 513 can be pushed, so that the rotating connecting rod 513 rotates and pushes the push-pull rod 511 through its upper end to slide in the direction away from the sliding ring 507, thereby driving the L-shaped clamping rod 512 to disengage from the clamping hole 504. At this time, the staff can push the sliding plug plate 501 to make another filter disc 502 enter the interior of the T-tube 401, and then release the push on the sliding ring 507. At this time, under the resilience of the return spring 506, the sliding ring 507 slides downward and drives the arc plug 509 to be inserted into the outer arc plug again. The L-shaped clamping rod 512 in the groove 503 is clamped with another clamping hole 504, thereby completing the fixation of the sliding plug plate 501 again. At this time, the filter plate 502 that slides out from the T-shaped tube 401 can be replaced and cleaned, so that the replacement and cleaning process of the filter plate 502 is continuous and can be completed without closing the T-shaped tube 401, thereby achieving work and replacement at the same time, further improving the cleaning efficiency of the plastic parts. At the same time, through simple sliding, the clamping of multiple L-shaped clamping rods 512 and the clamping holes 504, the insertion and limiting of the arc-shaped insert piece 509 and the arc-shaped slot 503 can be achieved. Compared with the bolt fixing in the prior art, it does not require the use of tools and the rotation operation of multiple bolts. Not only is the replacement process more convenient, but also the fixing effect of the sliding plug plate 501 is guaranteed by fixing and limiting the multiple sides of the sliding plug plate 501, thereby ensuring the stability of the filter plate 502 during filtering.
