DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] This embodiment discloses an easy-to-clean high-efficiency washing kettle, referring to Figure 1 , including a kettle body 1 and a cleaning device. The kettle body 1 is cylindrical and has a conical lower end. A feed inlet 12 and a water inlet 11 are provided at the upper end of the kettle body 1. Plastic particles to be cleaned enter the kettle body 1 of the washing kettle from the feed inlet 12, and a cleaning agent for cleaning the plastic particles enters the kettle body 1 from the water inlet 11. A water outlet 13 is provided at the lower end of the conical part of the kettle body 1. After cleaning, the used cleaning agent and the dirt cleaned are discharged from the kettle body 1 from the water outlet 13. A discharge port is also provided on the conical surface of the conical part of the kettle body 1. The cleaned plastic particles can leave the kettle body 1 from the discharge port, completing the discharge of the plastic particles. The setting of these interfaces provides convenience for the cleaning operation.

[0034] refer to Figure 2 The kettle body 1 is provided with a stirring device 2 inside, and the stirring device 2 includes a stirring shaft 21 and a stirring blade 22. The stirring shaft 21 is coaxially rotatably connected to the kettle body 1, and the stirring blade 22 is spirally fixed to the circumference of the stirring shaft 21. A servo motor 23 is fixed at a position corresponding to the stirring shaft 21 on the kettle body 1, and the output shaft of the servo motor 23 is coaxially fixed to one end of the stirring shaft 21. The servo motor 23 drives the stirring shaft 21 to rotate, and the stirring shaft 21 rotates and drives the stirring blade 22 to rotate to stir the plastic particles in the kettle body 1.

[0035] refer to Figure 2 and 3The cleaning device includes two groups of cleaning components 3, and the two groups of cleaning components 3 are coaxially arranged in the vertical direction. Each group of cleaning components 3 includes a plurality of scrapers 31 and a telescopic rod 32, and the telescopic rod 32 corresponds to the scrapers 31 one by one. The scrapers 31 are arc-shaped, and the curvature of the scrapers 31 is adapted to the curvature of the inner wall of the kettle body 1. One end of the scrapers 31 close to the kettle body 1 abuts against the inner wall of the kettle body 1, and the other end of the scrapers 31 is connected to the telescopic rod 32. The scrapers 31 always abut against the inner wall of the kettle body 1 under the action of the telescopic rod 32. The plurality of scrapers 31 of each group of cleaning components 3 are arranged in an array along the circumferential direction of the kettle body 1, and gaps are provided between adjacent scrapers 31. The scrapers 31 of the two groups of cleaning components 3 are staggered, and the parts of all scrapers 31 of the two groups of cleaning components 3 abutting against the inner wall of the kettle body 1 can completely cover the circumferential direction of the inner wall of the kettle body 1 together.

[0036] refer to Figure 2 and 3 A convex rib 16 is fixedly arranged on the kettle body 1 at a position corresponding to any scraper 31 in the cleaning assembly 3 located on the upper side, and the convex rib 16 is arranged parallel to the axial direction of the stirring shaft 21. A convex block 312 corresponding to the convex rib 16 is fixedly arranged on the side of the scraper 31 at the position corresponding to the convex rib 16 close to the inner wall of the kettle body 1, and the convex block 312 is clamped on both sides of the convex rib 16 along the width direction, and the scraper 31 can slide along the length direction of the convex rib 16.

[0037] refer to Figure 2 and 3 , a slide bar 33 is arranged between adjacent scrapers 31, and a slide groove 311 is arranged on the scraper 31 at a position corresponding to the slide bar 33. The slide bar 33 can slide in the slide groove 311, and a return spring 331 is fixed between adjacent slide bars 33, and the return spring 331 is located in the slide groove 311 of the scraper 31. The return spring 331 gives a force to the two slide bars 33 at both ends of itself to move away from each other. When the cleaning component 3 moves to the conical part of the kettle body 1, the circumference of the inner wall of the kettle body 1 abutted by the scrapers 31 of the same group of cleaning components 3 is reduced, and the distance between the adjacent scrapers 31 is reduced, so that the two adjacent slide bars 33 squeeze the return spring 331 located therebetween at the same time, compressing the length of the return spring 331, so that the scraper 31 can better adapt to the shape of the inner wall of the kettle body 1 and maintain a stable contact force during the cleaning process.

[0038] refer to Figure 2 and 3, one end of the telescopic rod 32 away from the scraper 31 is fixedly connected with a slider 34, and the slider 34 is sleeved on the stirring shaft 21. A spiral single groove 341 is provided on the slider 34, and the guide angle of the single groove 341 of the slider 34 is the same as the guide angle of the stirring blade 22. When the slider 34 moves along the axial direction of the stirring shaft 21, the single groove 341 of the slider 34 can be clamped on the stirring blade 22, so that the slider 34 moves along the spiral extension trajectory of the stirring blade 22. The cooperation between the scraper 31 provided with the protrusion 312 and the convex ridge 16 prevents the slider 34 from rotating with the rotation of the stirring shaft 21. When the servo motor 23 drives the stirring shaft 21 to rotate forward, the slider 34 moves vertically downward along the axial direction of the stirring shaft 21; when the servo motor 23 drives the stirring shaft 21 to reverse, the slider 34 moves vertically upward along the axial direction of the stirring shaft 21.

[0039] refer to Figure 2 and 3 The telescopic rod 32 includes an inner rod 322 and an outer rod 321 which are coaxially arranged. The outer rod 321 is sleeved outside the inner rod 322. The inner rod 322 can slide along the axis direction of the outer rod 321. One end of the inner rod 322 is fixed to the side of the scraper 31 away from the inner wall of the kettle body 1, and one end of the outer rod 321 is fixed to the slider 34. An abutment spring 323 is fixed to the end of the inner rod 322 away from the scraper 31, and the other end of the abutment spring 323 can be fixed to the outer rod 321. The abutment spring 323 provides a force to the inner rod 322 in a direction away from the slider 34, so as to provide a buffer force for the telescopic rod 32 during the telescopic process and maintain its stability.

[0040] The implementation principle of the embodiment of the present application is as follows: when in use, the plastic particles to be cleaned are added into the kettle body 1 through the feed port 12, and an appropriate amount of cleaning liquid is injected into the kettle body 1 through the water inlet 11. The stirring device 2 is started, and the stirring shaft 21 drives the stirring blade 22 to rotate to stir the plastic particles and the cleaning agent. At the same time, the stirring shaft 21 drives the scraper 31 to move along the inner wall of the kettle body 1 through the slider 34 and the telescopic rod 32. During the movement, the scraper 31 scrapes off the dirt and sediment on the inner wall of the kettle body 1 and makes it fall into the bottom of the kettle body 1. When drainage is required, the drain port is opened and the sewage is discharged. The filter screen 15 can prevent dirt and sediment from being discharged with the drain port. During the cleaning process or after cleaning, the sewage and the cleaned dirt can be discharged through the drain port. The setting of the cleaning device realizes the automatic cleaning of the inner wall of the washing kettle, improves the cleaning efficiency and washing effect, reduces the cost and risk of manual cleaning, and improves the product quality in the subsequent production process. After the cleaning is completed and the cleaning liquid is discharged, the plastic particles are discharged from the discharge port to complete the overall cleaning work.

[0041] refer to Figure 2 and 3As a further example of this embodiment, a filter screen 15 is provided near the drain outlet of the kettle body 1. The mesh size of the filter screen 15 is smaller than the size of the plastic particles to be cleaned. At the same time, the filter screen 15 allows the cleaning agent and the dirt and sediment attached to the plastic particles to pass through and be discharged from the drain outlet. The filter screen 15 prevents the cleaned plastic particles from being discharged from the water inlet 11, effectively avoiding the problem of plastic particles blocking the drain outlet and avoiding the loss of plastic particles.

[0042] refer to Figure 2 and 3 In order to further optimize the cleaning effect, the scraper 31 in this embodiment can also be tilted. Specifically, the side of the scraper 31 close to the inner wall of the kettle body 1 is lower than the side away from the inner wall of the kettle body 1. Such a design can make the scraper 31 better adapt to the shape change of the inner wall of the kettle body 1 during the cleaning process, thereby improving the cleaning effect.

[0043] refer to Figure 2 and 3 As a further example under this embodiment, the scraper 31 in this embodiment can also be made of a flexible material, such as rubber or plastic, so that the scraper 31 has better elastic deformation ability. Such a material can deform to a certain extent when the scraper 31 is squeezed, so as to better adapt to the shape change of the inner wall of the kettle body 1 and further improve the cleaning effect.

[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
