Description

Technical Field

[0001] This application relates to the technical field of plastic product manufacturing equipment, and in particular to a dust removal device for plastic product manufacturing and processing. Background Technology

[0002] During the production and processing of plastic products, a large number of defective plastic products are generated. To achieve resource recycling, these defective plastic products are usually crushed. However, this crushing process produces a large amount of special dust. Due to the material characteristics of the defective plastic products themselves, the dust particles formed after crushing are hard, and some particles have sharp edges. Under negative pressure suction, these dust particles flow at high speed within the dust collection device. The sharp edges can easily cause wear to the filter components of the dust collection device, thus affecting the dust collection efficiency.

[0003] A search revealed Chinese Patent Publication No. CN222726314U, which discloses a plastic shredder with a dust removal mechanism. The shredder includes a dust-collecting component connected to the top of the base, a support component connected to the top of the base, a lifting component connected to the top of the base, and a grinding component connected to the lifting component for limiting and adjusting the plastic parts. The grinding component includes a sliding handle connected to a sliding plate, a drive wheel rotatably connected to the sliding plate, and a grinding belt fitted onto the drive wheel for grinding the surface of the plastic parts.

[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: in the prior art, some of the pulverized dust particles have sharp edges, causing damage to the filter components when the dust particles flow at high speed within the dust removal equipment. To address the technical problem of some dust particles with sharp edges damaging the filter components when flowing at high speed within the dust removal equipment, this application proposes a solution. This is achieved by installing staggered first and second baffles within the dust collection chamber to block large dust particles and reduce their direct impact on the filter plates. Furthermore, a cleaning component is provided to clean the dust from the baffles, thus reducing filter plate wear and maintaining dust removal efficiency. Utility Model Content

[0005] In order to reduce the wear of filter plates and thus improve dust removal efficiency, this application provides a dust removal device for the production and processing of plastic products.

[0006] This application provides a dust removal device for plastic product manufacturing and processing, employing the following technical solution: It includes a dust collection box with openings at both ends. A fan is installed at one end of the dust collection box. Multiple first baffles are installed on the top wall of the inner cavity of the dust collection box, with a gap between the lower end face of each first baffle and the bottom wall of the inner cavity. Multiple second baffles are installed on the bottom wall of the inner cavity of the dust collection box, with each second baffle located between two first baffles, and a gap between the upper end face of each second baffle and the top wall of the dust collection box. A hollow filter box is connected to the other end of the dust collection box, and a filter plate is detachably connected inside the filter box. A cleaning assembly is also installed inside the dust collection box. The multiple first and second baffles form a gas channel, causing larger and sharp dust particles to settle, thereby improving the service life of the filter plate.

[0007] Optionally, a first sliding hole is provided on the rear side wall of the dust collection box, and a first sliding rod is slidably connected in the first sliding hole; a cleaning plate located in the inner cavity of the dust collection box is fixedly installed on the first sliding rod.

[0008] Optionally, the cleaning plate is adapted to the front side wall of the dust collector cavity, and the cleaning plate is provided with a plurality of first passage slots and second passage slots; the first passage slots are adapted to the first baffle plate, and the second passage slots are adapted to the second baffle plate.

[0009] Optionally, the front side wall of the dust collector is provided with a second through groove communicating with the inner cavity; the front side wall of the dust collector is hinged with a baffle adapted to the second through groove.

[0010] Optionally, the front side wall of the dust collector is provided with a first rotating seat, and a first rotating rod that is rotatably connected to the first rotating seat is fixedly provided on the baffle.

[0011] Optionally, a torsion spring is fitted on the outer wall of the first rotating rod, with one end of the torsion spring fixedly connected to the first rotating seat and the other end fixedly connected to the baffle; the elastic force of the torsion spring can overcome the airflow pressure generated by the fan.

[0012] Optionally, the cleaning plate is provided with a stop block on the side facing the baffle.

[0013] Optionally, a blocking plate is fixedly provided on the first sliding rod, and a second compression spring is sleeved on the outer wall of the first sliding rod; one end of the second compression spring is fixedly connected to the rear side wall of the dust collector, and the other end is fixedly connected to the blocking plate.

[0014] In summary, this application includes the following beneficial technical effects: 1. This utility model forms a tortuous airflow channel by setting up staggered first and second baffles inside the dust collector. When the dust-laden airflow passes through, large dust particles (especially hard particles with sharp edges) will collide with the surface of the baffles due to inertia or settle, which greatly reduces the amount of particles that directly impact the filter plates in the filter box, reduces the wear of the filter plates, and extends the replacement cycle of the filter components.

[0015] 2. This utility model allows the cleaning plate to slide by pushing the first sliding rod. The first and second through grooves on the cleaning plate scrape away dust adhering to the surfaces of the first and second baffle plates. Simultaneously, during the cleaning process, the abutment on the cleaning plate pushes open the baffle, allowing dust to be discharged from the second through groove. After cleaning, the cleaning plate can return to its original position under the action of the second compression spring, and the baffle can automatically close the through groove under the action of the torsion spring, ensuring the continuity and efficiency of the dust removal process and reducing the inconvenience of manual cleaning.

[0018] The following is in conjunction with the appendix Figures 1-5 This application will be further described in detail below. The technical solutions in the embodiments of this application will be clearly described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0019] This application discloses a dust removal device for the production and processing of plastic products. For example... Figure 1 As shown, this embodiment includes a dust collection box 1 and a filter box 2. The dust collection box 1 is a cuboid structure with openings at both the left and right ends. A fan 3 is fixed to the left opening with bolts to generate negative pressure airflow. The right opening of the dust collection box 1 is connected to a hollow filter box 2. A filter plate 4 is detachably connected to the filter box 2 through a slot to filter fine dust.

[0020] Multiple first baffles 5 are fixedly fixed at intervals along the left and right direction on the top wall of the inner cavity of the dust collector 1. Each first baffle 5 extends vertically downward, and its lower end face leaves a gap with the bottom wall of the inner cavity of the dust collector 1 for airflow to pass through. Multiple second baffles 6 are welded to the bottom wall of the inner cavity of the dust collector 1. Each second baffle 6 is located between two adjacent first baffles 5, and the second baffle 6 extends vertically upward, and its upper end face leaves a gap with the top wall of the dust collector 1 for airflow to pass through. The first baffle plate 5 and the second baffle plate 6 are staggered to form an airflow channel. When the fan 3 is working, the dust-laden airflow enters from the left end of the dust collection box 1. After being blocked by the baffle plate, large dust particles, especially hard particles with sharp edges, collide with the surface of the baffle plate due to inertia or settle down, reducing the amount of particles that directly impact the filter plate 4 and effectively reducing the wear of the filter plate 4.

[0021] like Figure 2 , Figure 4 As shown, the dust collector 1 is equipped with a cleaning component for cleaning dust adhering to the surface of the baffle plate, specifically including a first sliding hole 7 and a first sliding rod 8; a horizontal first sliding hole 7 is opened on the rear side wall of the dust collector 1, and a first sliding rod 8 is slidably connected in the first sliding hole 7. A cleaning plate 9 located in the inner cavity of the dust collector 1 is fixedly installed at the front end of the first sliding rod 8, and a push-pull handle 10 is fixedly installed at the rear end of the first sliding rod 8 to the outside of the dust collector 1; The cleaning plate 9 is a rectangular plate adapted to the front side wall of the inner cavity of the dust collector 1. It has multiple first passage slots 11 and multiple second passage slots 12. The shape and size of the first passage slots 11 are adapted to the corresponding surface of the first baffle plate 5, and the second passage slots 12 are adapted to the corresponding surface of the second baffle plate 6. This ensures that when the cleaning plate 9 slides left and right, the first baffle plate 5 can pass through the first passage slot 11 and the second baffle plate 6 can pass through the second passage slot 12, thereby scraping off the dust on the surface of the baffle plate. A blocking plate 13 is fixedly installed on the first sliding rod 8 outside the dust collection box 1, and a second compression spring 14 is sleeved on its outer wall; one end of the second compression spring 14 is welded to the rear side wall of the dust collection box 1, and the other end is welded to the blocking plate 13; when the first sliding rod 8 is pushed to move the cleaning plate 9 forward, the second compression spring 14 is compressed; after the push-pull handle 10 is released, the elastic force of the second compression spring 14 can drive the cleaning plate 9 to return to its original position.

[0022] A second through groove 15, which communicates with the inner cavity, is opened on the front side wall of the dust collector 1. The size of the second through groove 15 is slightly larger than the corresponding surface of the cleaning plate 9, and is used to discharge the dust being cleaned. A baffle 16 is provided on the front side wall of the dust collector 1 to close the second through groove 15. Two first rotating seats 17 are fixedly installed on the front side wall of the dust collector 1. First rotating rods 18 are fixedly installed at the upper and lower ends of the baffle 16 respectively. The first rotating rods 18 are rotatably connected to the first rotating seats 17 to realize the opening and closing of the baffle 16. A torsion spring 19 is sleeved on the outer wall of the first rotating rod 18. One end of the torsion spring 19 is fixedly connected to the first rotating seat 17 and the other end is fixedly connected to the baffle 16. The elastic force of the torsion spring 19 is set to overcome the airflow pressure generated by the fan 3, ensuring that the baffle 16 always closes the second passage 15 when the fan 3 is working, and avoiding airflow leakage. A stop block 20 is welded to the side of the cleaning plate 9 facing the baffle 16. When the cleaning plate 9 moves towards the baffle 16, the stop block 20 can push the baffle 16, so that the baffle 16 overcomes the elastic force of the torsion spring 19 and flips open, so that the dust that is easy to clean can be discharged from the second passage 15.

[0023] Work process: When the fan 3 is started, the dust-laden airflow enters from the right end of the dust collector 1. When it passes through the tortuous channel formed by the first baffle plate 5 and the second baffle plate 6, large dust particles are blocked and adhere to the surface of the baffle plates. The remaining dust-laden airflow enters the filter box 2, and after being filtered by the filter plate 4, the clean airflow is discharged. When there is a lot of dust on the surface of the baffle plate, push the push-pull handle 10 of the first sliding rod 8 to move the cleaning plate 9 forward; the first through groove 11 and the second through groove 12 of the cleaning plate 9 scrape the dust off the surface of the baffle plate, and at the same time the abutment block 20 pushes the baffle 16, so that the baffle 16 opens against the elastic force of the torsion spring 19; after the dust is discharged from the second through groove 15, release the push-pull handle 10, the second compression spring 14 drives the cleaning plate 9 to reset, and the baffle 16 re-closes the second through groove 15 under the action of the torsion spring 19; When filter plate 4 becomes clogged or malfunctions, simply remove filter plate 4 from the slot and replace it.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
