Technical Field

[0001] The utility model relates to the technical field of production and processing of plastic products, in particular to a cleaning and drying device for the production of PP modified particles. Background Art

[0002] Patent publication number CN108058409B discloses a plastic pellet washing and drying machine, comprising a frame, a washing drum, and a spin-drying plate disposed therein. A partition is provided at the lower portion of the frame's inner cavity, dividing the inner cavity into an upper and lower chamber, with the lower chamber containing a cleaning liquid at a predetermined level. The washing drum is located at the upper portion of the inner cavity, and a first rotating shaft is disposed within the washing drum, with spiral blades disposed around the outer periphery of the shaft. Discharge ports are symmetrically provided on either side of the top of the washing drum, connected to a discharge pipe with the outlet facing downward. The spin-drying plate is disposed below the washing drum, and an electric heating plate is provided at the bottom of the spin-drying plate. Symmetrical holes for cleaning liquid are provided on either side of the partition. This invention combines the cleaning and drying processes of plastic pellets, improving work efficiency. It also features a simple structure and convenient operation.

[0003] There are two problems with the above technology when it is used. First, after the plastic particles are continuously turned over by the spiral blades in the cleaning liquid, the cleaning liquid will be contaminated. In order to ensure the cleaning effect of the plastic particles, the cleaning liquid needs to be replaced frequently, resulting in a lot of waste.

[0004] Second, when the plastic particles are being spun on the drying plate, the filter will filter the stains in the water spun out by the plastic particles on its water-facing surface. Over time, a large amount of stains will adhere to the inner wall of the baffle, which will not only reduce the filtering effect of the baffle, but also cause secondary pollution to the plastic particles. Utility Model Content

[0005] The purpose of the utility model is to provide a cleaning and drying device for producing PP modified particles.

[0006] The technical problems solved by the present invention are: 1. The cleaning fluid needs to be replaced in time after being contaminated, which will cause a lot of waste; 2. After the filter screen filters the moisture in the plastic particles, stains will adhere to its water-facing surface. If this continues for a long time, the filtering effect of the baffle will be reduced and secondary pollution will be caused to the plastic particles.

[0007] The utility model can be realized through the following technical scheme: it includes a water-throwing net drum that is rotatably installed through the top of the box body, a discharge port is opened on one side of the top of the water-throwing net drum, a plurality of equidistant annular array limit bars are fixedly installed on the inner peripheral wall of the water-throwing net drum, the inner side of the water-throwing net drum is slidably connected to a leakage bottom plate through a plurality of limit bars, a stirring rod that can move up and down in the vertical direction is rotatably installed on the top of the leakage bottom plate, a filter plate is fixedly installed at a position below the water-throwing net drum in the inner cavity of the box body, a scraping brush plate is fixedly installed at the bottom of the water-throwing net drum, and the bottom of the scraping brush plate is in contact with the top of the filter plate, an injection mechanism is installed in the inner cavity of the box body to spray cleaning liquid into the water-throwing net drum, and a plurality of heating plates are fixedly installed in the inner cavity of the box body.

[0008] A further technical improvement of the utility model is that a gear ring is fixedly installed on the outer peripheral wall of the water-spinning net cylinder, and a gear meshing with the gear ring is rotatably installed on the top of the box inner cavity.

[0009] Furthermore, one side of the filter plate is inclined to the ground, and a sewage outlet is fixedly connected to one side of the outer peripheral wall of the box corresponding to the lowest point of the inclined surface of the filter plate.

[0010] Furthermore, the bottom of the scraper plate is configured as a brush.

[0011] Furthermore, the spraying mechanism includes drainage pipes fixedly installed on the inner walls on both sides of the inner cavity of the box body, and the two drainage pipes are fixedly connected to a number of equally distributed high-pressure nozzles on one side adjacent to the water-throwing net cylinder. A connecting pipe fixedly installed on the inner peripheral wall of the box body is fixedly connected to the two drainage pipes at the same time. A water supply pipe is fixedly connected to one side of the box body, one end of the water supply pipe is fixedly connected to the connecting pipe, and the other end of the water supply pipe extends to the bottom of the inner cavity of the box body and is fixedly connected to a water suction head.

DETAILED DESCRIPTION

[0021] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0022] See also Figure 1-3 As shown, this embodiment provides a cleaning and drying device for producing PP modified particles, including a box body 1, a water-spinning net cylinder 2 is rotatably installed on the top of the box body 1, a discharge port 3 is opened on one side of the top of the water-spinning net cylinder 2, a plurality of equidistant annular array limit bars 4 are fixedly installed on the inner circumferential wall of the water-spinning net cylinder 2, a water leakage bottom plate 5 is slidably connected to the inner side of the water-spinning net cylinder 2 through the plurality of limit bars 4, a stirring rod 6 is rotatably installed on the top of the water leakage bottom plate 5, a support frame 7 is fixedly installed on the top of the box body 1, and an electric push rod for driving the stirring rod 6 to move vertically up and down is installed on the support frame 7;

[0023] When the stirring rod 6 moves up and down in the vertical direction, it will drive the water leakage bottom plate 5 to move synchronously along the plurality of limit bars 4. When the stirring rod 6 moves to the lowest point in the vertical direction, it just drives the water leakage bottom plate 5 to move to the lowest point of the water-spinning net cylinder 2. When the stirring rod 6 moves to the highest point in the vertical direction, it just drives the water leakage bottom plate 5 to move to a position flush with the discharge port 3.

[0024] A gear ring 8 is fixedly installed on the outer peripheral wall of the water-throwing net cylinder 2, and a gear 9 meshing with the gear ring 8 is rotatably installed on the top of the inner cavity of the box body 1. A driving motor for driving the gear 9 is installed on the top of the box body 1. A filter plate 10 is fixedly installed at a position below the inner cavity of the box body 1 corresponding to the water-throwing net cylinder 2. One side of the filter plate 10 is inclined to the ground (not shown in the figure), and a sewage outlet 11 is fixedly connected to the side of the outer peripheral wall of the box body 1 corresponding to the lowest part of the inclined surface of the filter plate 10. A scraper plate 12 is fixedly installed at the bottom of the water-throwing net cylinder 2, and the bottom of the scraper plate 12 is set to a brush, and the bottom of the scraper plate 12 is in contact with the top of the filter plate 10;

[0025] When the gear 9 rotates, it drives the water-spinning net cylinder 2 to rotate through the ring gear 8. The rotating water-spinning net cylinder 2 drives the leakage bottom plate 5 to rotate synchronously through the limit bar 4. The leakage bottom plate 5 cooperates with the rotating water-spinning net cylinder 2 to drive the plastic particles inside it to move synchronously, so that it and the stirring rod 6 are in a relative rotation state, prompting the stirring rod 6 to stir the plastic particles. At the same time, the water-spinning net cylinder 2 also drives the scraping plate 12 to scrape the filter plate 10, so as to scrape the stains attached to the top of the filter plate 10 to the sewage outlet 11 for discharge;

[0026] A water inlet pipe 13 is fixedly connected to the position below the filter plate 10 on the outer peripheral wall of the box body 1. A plurality of heating plates 14 in a circular array surrounding the water-throwing net cylinder 2 are fixedly installed on the top of the inner cavity of the box body 1. A heater for heating the heating plate 14 is installed on the top of the box body 1. Drain pipes 15 are fixedly installed on the inner walls on both sides of the inner cavity of the box body 1. The two drain pipes 15 are fixedly connected to a plurality of equally distributed high-pressure nozzles 16 on one side adjacent to the water-throwing net cylinder 2. A connecting pipe 17 fixedly connected to the two drain pipes 15 is fixedly installed on the inner peripheral wall of the box body 1. A water pipe 18 is fixedly connected to one side of the box body 1. One end of the water pipe 18 is fixedly connected to the connecting pipe 17, and the other end of the water pipe 18 extends to the bottom of the inner cavity of the box body 1 and is fixedly connected to a water suction head 19. A water pump is installed on the water pipe 18 to promote the water pipe 18 to pump liquid into the connecting pipe 17;

[0027] Cleaning liquid can be injected into the bottom of the inner cavity of the box body 1 through the water inlet pipe 13. While the water-throwing net cylinder 2 rotates, the water delivery pipe 18 transports the cleaning liquid at the bottom of the inner cavity of the box body 1 to the connecting pipe 17 through the water suction head 19, and then transports the cleaning liquid to the two drain pipes 15 through the connecting pipe 17, prompting the drain pipes 15 to spray the cleaning liquid onto the water-throwing net cylinder 2 through a number of high-pressure nozzles 16. The cleaning liquid sprayed by the high-pressure nozzles 16 will pass through the mesh of the water-throwing net cylinder 2 to flush the plastic particles. The wastewater generated at this time will flow to the filter plate 10 through the mesh on the water-throwing net cylinder 2 and the mesh on the leaking bottom plate 5. The liquid filtered by the filter plate 10 will flow to the cleaning liquid at the bottom of the inner cavity of the box body 1 for recycling.

[0028] When the utility model is in use, the plastic particles are first poured into the water-spinning net cylinder 2, and the cleaning liquid with the liquid level lower than the lowest point of the filter plate 10 is injected into the bottom of the inner cavity of the box body 1 through the water inlet pipe 13, and then the water-spinning net cylinder 2 is rotated, thereby prompting the stirring rod 6 to stir the plastic particles, and then the cleaning liquid at the bottom of the inner cavity of the box body 1 is pumped into the connecting pipe 17 through the conveying pipe, so that the connecting pipe 17 conveys the cleaning liquid to the drain pipe 15, prompting the drain pipe 15 to spray the cleaning liquid into the water-spinning net cylinder 2 through the high-pressure nozzle 16 to flush the plastic particles. At this time, the wastewater generated will pass through the filter plate The filtered water 10 flows into the cleaning liquid at the bottom of the inner cavity of the box body 1 for recycling. After the plastic particles are flushed clean, the water pipe 18 stops pumping water, and then the heating plate 14 is heated, so that the heating plate 14 heats the plastic particles in the water-throwing net cylinder 2 to dry the plastic particles. When the plastic particles are dried, the drying net cylinder stops rotating, and then the stirring rod 6 drives the leaking net plate to move upward to a position flush with the discharge port 3, so that the leaking net plate moves the plastic particles in the water-throwing net cylinder 2 to the discharge port 3, prompting the plastic particles to be discharged through the discharge port 3.
