Description

Technical Field

[0001] This utility model belongs to the field of waste collection technology, and in particular relates to a waste collection device for powder coating processing. Background Technology

[0002] As people's demands for health and environmental protection increase, although the traditional carboxylated polyester / TGIC (triglycidyl isocyanate) system is homogeneous, stable, and tunable, with good heat and weather resistance that can basically meet user requirements, its strong pungent odor and potential carcinogenicity make its withdrawal from the market inevitable. Hydroxyalkylamide compounds are recognized as low-toxicity and environmentally friendly compounds and are now widely used in daily chemicals, surfactants, and coatings. Currently, hydroxyalkylamide systems have gradually replaced carboxylated polyester / TGIC as the most important component of outdoor powder coating systems.

[0003] Chinese utility model patent CN219292161U discloses a waste collection device for powder coating processing, relating to the field of powder coating processing technology. This utility model provides a waste collection device for powder coating processing, comprising a collection cart and a collection assembly. The upper end of the collection cart has a sealing cover that opens and closes, and the sealing cover is engaged with the collection cart via a sealing groove. Wheels are symmetrically arranged on the left and right sides of the lower end of the collection cart, and a rotating shaft is connected between the wheels. The rotating shaft is connected to the collection cart via a mounting block. A pusher is welded to the back end of the collection cart, and an exhaust box protrudes from the lower end of the pusher. This utility model has the advantages of being able to screen out large particulate impurities in waste, pre-cleaning clumped and sticky waste, improving collection rate and recycling standards, having a simple structure, being easy to use, and having high flexibility.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] 1. The above-mentioned device draws powder and impurities into the collection vehicle through negative pressure suction and uses a filter screen to intercept the powder and impurities. However, after the above-mentioned device has been working for a long time, impurities or powder will accumulate on the filter screen, causing blockage of the screen holes. In addition, the above-mentioned device lacks a cleaning device for the filter screen, which affects the air circulation.

[0006] Second, the above-mentioned device uses the circular motion of a broom to clean up powder and impurities. However, the broom cannot break up powder that is stuck in clumps. In addition, its motion will sweep the accumulated powder to any other location in the work area, thereby increasing the workload of the subsequent collection pipe and making it difficult for the powder to be quickly absorbed by the collection pipe. Utility Model Content

[0007] This utility model provides a waste collection device for powder coating processing, aiming to solve the problems mentioned in the background art. Due to the lack of a cleaning device on the filter screen, the sieve holes on the filter screen will become clogged after long-term use, thus affecting air circulation. In addition, the above-mentioned device uses a broom to break up the accumulated powder and sweep it to any other location in the work area, and it cannot break up powder that is stuck together. This method increases the workload of the collection pipe and cannot quickly absorb the powder into the collection vehicle.

[0008] This utility model is implemented as follows: a waste collection device for powder coating processing includes: a collection device, wherein a collection pipe is connected to the inner bottom wall of the collection device; a first filter screen and a second filter screen are sequentially and spaced apart inside the collection device on one side of the collection pipe, the first filter screen being located on the side of the second filter screen closer to the collection pipe; a negative pressure fan, which is fixedly installed on one side wall of the collection device and located on the side of the first and second filter screens away from the collection pipe, the air inlet of the negative pressure fan being connected to the inner cavity of the collection device; and a cleaning mechanism, which is rotatably connected inside the collection device and movably connected to the first and second filter screens, and is used to clean the waste adhering to the first and second filter screens. The device cleans the deposits on the surface using a fragmentation mechanism, which is movably installed at the bottom of the collection device and located in front of the collection pipe in the direction of movement. In this scheme, the device uses negative pressure generated by a negative pressure fan to draw powder coating waste and impurities into the collection device through the collection pipe. The first filter screen filters and intercepts the impurities, and the second filter screen intercepts the powder coating particles. With the cleaning mechanism installed, after the device has been working for a long time, the rotation of the output end of the rotating motor drives the rotating shaft to rotate. The rotating shaft drives the rotating sleeve on one side of the first and second filter screens to rotate, and the rotating sleeve drives the scraper to scrape the first and second filter screens, thereby cleaning the deposits attached to the first and second filter screens and ensuring normal air circulation.

[0009] In addition, this device is equipped with a pressure roller on the front side of the collection pipe. When the powder coating adheres and forms lumps, the pressure roller can crush the lumps. At the same time, when the lumps are more stubborn, the drive motor drives the eccentric block to rotate. When the eccentric block contacts the protrusion, it drives the sliding block to move upward in the strip groove and squeezes the return spring. When the eccentric block disengages from the protrusion, the pressure roller presses down and smashes the lumps under the rebound drive of the return spring, thereby crushing the material through impact. The material is then absorbed into the collection device by the collection pipe, completing the collection and treatment of waste.

[0010] Preferably, the cleaning mechanism includes: a rotating motor fixedly installed on the side wall of the collecting device, and through holes are provided on both the first and second filter screens; a rotating shaft passing through the two through holes and having one end fixedly connected to the output end of the rotating motor; a rotating sleeve fixedly connected to the outer wall of the rotating shaft on the side of the first and second filter screens near the collecting pipe; at least one scraper fixedly connected to the outer wall of the rotating sleeve; and the side wall of the scraper abutting against the side walls of the first and second filter screens. In this scheme, when the output end of the rotating motor rotates, it drives the rotating shaft to rotate, and the rotating shaft controls the rotating sleeve on its outer wall to rotate. The rotating sleeve drives the scraper to rotate around the rotating shaft, and one side wall of the scraper abuts against the first and second filter screens. Therefore, the movement of the scraper will scrape off the adhering substances on the first and second filter screens, thereby preventing the screen holes from being blocked and affecting the normal flow of subsequent air.

[0011] Preferably, the first filter and the second filter are fixedly installed in the collection device by a mounting bracket, and the mounting bracket includes: mounting blocks symmetrically fixed to the inner walls of both sides of the collection device, and assembly slots vertically formed on the side walls of the two mounting blocks that are close to each other. A rectangular frame is fixedly installed on the outer side of the first filter and the second filter, and assembly blocks are integrally formed and fixed to the outer walls of both sides of the rectangular frame. The assembly blocks are detachably and movably installed in the assembly slots. In this scheme, when assembling the first filter and the second filter, the rectangular frames on the outer side of the first filter and the second filter are first aligned between the two mounting blocks to be assembled. Then, the assembly blocks on the side walls of the rectangular frame are inserted into the assembly slots formed on the side walls of the mounting blocks. Next, the rectangular frame is pressed down. After the assembly blocks and the assembly slots are completely fitted, the assembly of the first filter and the second filter is completed.

[0012] Preferably, the crushing mechanism includes: a mounting base fixed to the bottom wall of the collecting device, two mounting bases symmetrically distributed on both sides of the collecting pipe, a strip groove opened on the side wall of the two collecting pipes that are close to each other, a guide rod fixedly fixed vertically in the strip groove, a sliding block sleeved on the outside of the guide rod that slides with the strip groove, a return spring sleeved on the outside of the guide rod above the sliding block, and a pressure roller rotatably connected between the two sliding blocks; in this scheme, sliding blocks are slidably connected on the side wall of the two mounting bases that are close to each other, and a pressure roller is rotatably connected between the two sliding blocks. The pressure roller can be used to crush the block material, thereby achieving effective collection of powder coating.

[0013] Preferably, a connecting plate is fixed to the side wall of each of the two mounting seats away from the collecting pipe. A drive motor is fixed to the side wall of the connecting plate, and an eccentric block is fixed to its output end. A protrusion is fixed to the side wall of the sliding block facing the eccentric block. In this scheme, the drive motor drives the eccentric block to rotate. When the eccentric block contacts the protrusion, it drives the sliding block to move upward in the strip groove and squeezes the return spring. When the eccentric block disengages from the protrusion, the pressure roller presses down and smashes the block material under the rebound drive of the return spring, thereby breaking the material by impact.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a waste collection device for powder coating processing.

[0015] 1. By incorporating a cleaning mechanism, after the device has been in operation for an extended period, the rotation of the motor output can drive the rotating shaft to rotate. The rotating shaft drives the rotating sleeves on one side of the first and second filter screens to rotate, which in turn drives the scraper to scrape the first and second filter screens, thereby cleaning the deposits attached to the first and second filter screens and ensuring normal airflow.

[0016] 2. When powder coatings clump together, the pressure rollers can crush the clumps. If the clumps are stubborn, the drive motor rotates the eccentric block. When the eccentric block contacts the protrusion, it drives the sliding block to move upward in the slot, while squeezing the return spring. When the eccentric block disengages from the protrusion, the pressure rollers press down and strike the clumps under the rebound of the return spring, thus crushing the material through impact. The material is then absorbed into the collection device through the collection pipe, completing the collection and treatment of waste. Attached Figure Description
