Description

Technical Field

[0001] The invention relates to the technical field of recycling residual materials from plastic pellet processing, and in particular to a device for recycling residual materials from plastic pellet processing. Background Art

[0002] Plastics are widely used and are indispensable components in home appliances, automobiles, mobile phones, PCs, medical devices, and lighting appliances. However, a lot of waste materials are generated during the production process. In order to save energy and protect the environment, the waste materials need to be recycled and processed into plastic pellets.

[0003] Before the residual materials are processed into plastic pellets, they need to be crushed first, and then a crushing device is needed. However, the existing crushing device is not convenient for cleaning the residual materials after crushing them. The mud on the crushed residual materials will affect the molding and appearance of the products during the subsequent liquefaction. Although some crushing devices have a spray mechanism, water usually needs to be passed into a spray pipe, which sprays the water into a cleaning box, and then the water in the cleaning box is discharged from the sewage pipe, which requires more water sources and causes water waste.

[0035] As a further limitation of the cleaning mechanism 2 of the present invention, the spray unit 22 includes an L-shaped tube 2201 fixedly connected to the inner wall of the crushing box 1, and a high-pressure spray head 2202 is fixedly connected to the surface of the L-shaped tube 2201. The number of high-pressure spray heads 2202 is several, and one end of some high-pressure spray heads 2202 passes through the guide tube 2106 and extends to the inner cavity of the net tube 2108. One side of the cleaning box 11 is fixedly connected to a first water pump 2203, and the output end of the first water pump 2203 is fixedly connected to a connecting component 2204. One end of the connecting component 2204 passes through the inner cavity of the crushing box 1 and is fixedly connected to one side of the L-shaped tube 2201. The inner cavity of the cleaning box 11 A filter component 2205 is provided, and the filter component 2205 is used to filter the sewage in the cleaning box 11. By setting a spray component, when spraying, the first water pump 2203 is started by using an external control switch, so that the water in the cleaning box 11 enters the connecting component 2204, and the water is introduced into the inner cavity of the L-shaped tube 2201 through the connecting component 2204, so that the water is sprayed out from the high-pressure spray head 2202, which can not only flush the crushed residue in the inner cavity of the U-shaped plate 2102, but also perform secondary flushing on the crushed residue in the inner cavity of the mesh cylinder 2108, thereby increasing the cleaning effect, and the cleaned water can fall into the cleaning box 11 and be reused.

[0036] The filter assembly 2205 includes a turntable 2206 rotatably connected to the inner cavity of the cleaning box 11, a plurality of partitions 2207 are fixedly connected to the surface of the turntable 2206, one end of the plurality of partitions 2207 is commonly fixedly connected to a ring 2208, one side of the partitions 2207 is commonly fixedly connected to a filter membrane 2209, a scraper 2210 is fixedly connected to the inner wall of the cleaning box 11, one side of the scraper 2210 contacts one side of the filter membrane 2209, a fixed rod 2211 is fixedly connected to the inner wall of the cleaning box 11, an adjusting rod 2212 is slidably connected to one side of the fixing rod 2211, one end of the adjusting rod 2212 is fixedly connected to a knocking block 2213, a tension spring 2214 is movably sleeved on the surface of the adjusting rod 2212, one end of the tension spring 2214 is fixedly connected to the adjusting rod 2212, the other end of the tension spring 2214 is fixedly connected to the fixing rod 2211, and the surface of the ring 2208 is fixedly connected to the inner wall of the cleaning box 11.

[0040] Example 3: Please refer to Figure 1-Figure 10 The present invention provides a technical solution: a device for recovering residual materials from processing plastic pellets. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0041] The replacement mechanism 3 includes a movable plate 301 slidably connected to the inner cavity of the cleaning box 11, and a sealing ring 302 is fixedly connected to the surface of the movable plate 301.

By setting the replacement mechanism 3, when there is a lot of mud in the cleaning box 11, the movable plate 301 will press down on the detection end of the pressure sensor 303. When the downward pressing force is greater than the force set on the pressure sensor 303, the electromagnetic valve 304 is started to discharge the sewage in the cleaning box 11, and discharge the clean water from the outside from the connecting component 2204 into the cleaning box 11, thereby achieving the effect of replacing the water in the cleaning box 11.

[0042] The inner wall of the cleaning box 11 is fixedly connected with a telescopic rod 306, and the telescopic end of the telescopic rod 306 is fixedly connected to the bottom of the movable plate 301.

By setting the telescopic rod 306 and the spring 307 for use together, when sewage is discharged, the elastic force of the spring 307 will drive the movable plate 301 to move upward. By setting the telescopic rod 306, the effect of guiding the movable plate 301 can be achieved.

[0043] The connecting assembly 2204 includes a first connecting pipe 308, one end of which is fixedly connected to the output end of the first water pump 2203, one end of the first connecting pipe 308 is fixedly connected to a first one-way valve 309, one end of the first one-way valve 309 is fixedly connected to a second connecting pipe 310, one end of the second connecting pipe 310 passes through the inner cavity of the crushing box 1 and is fixedly connected to one side of the L-shaped pipe 2201, the surface of the second connecting pipe 310 is fixedly connected to a second one-way valve 311, one end of the second one-way valve 311 is provided with a second water pump 312, and the output end of the second water pump 312 is fixedly connected to the output end of the second water pump 312.

By setting the connecting component 2204, when the water in the cleaning box 11 is replaced, the first water pump 2203 is turned off and the second water pump 312 is started, and the water inlet pipe 313 is placed in the clean water tank, so that the clean water enters the second connecting pipe 310 through the second one-way valve 311, and is discharged into the inner cavity of the cleaning box 11 through the high-pressure sprinkler head 2202. The setting of the first one-way valve 309 can prevent clean water from entering the first connecting pipe 308 from the second connecting pipe 310.

[0044] A controller 314 is fixedly connected to one side of the crushing box 1, and the pressure sensor 303, the first water pump 2203, the second water pump 312 and the solenoid valve 304 are all electrically connected to the controller 314. By setting the controller 314, when the value detected by the pressure sensor 303 is greater than the set value, the controller 314 controls the first water pump 2203 to be closed, and the second water pump 312 and the solenoid valve 304 to be opened; when the value detected by the pressure sensor 303 is less than or equal to the set value, the first water pump 2203 is opened, and the second water pump 312 and the solenoid valve 304 are closed. The controller 314 can be a timing controller 314, which can set the opening time of the second water pump 312 and the solenoid valve 304. This is the prior art and will not be elaborated on in detail.

[0045] The specific implementation method of this embodiment is as follows: when there is a lot of mud in the cleaning box 11, the movable plate 301 will press down on the detection end of the pressure sensor 303. When the downward pressing force is greater than the force set for the pressure sensor 303, the solenoid valve 304 is started to discharge the sewage in the cleaning box 11. When replacing the water in the cleaning box 11, the first water pump 2203 is turned off and the second water pump 312 is started. The water inlet pipe 313 is placed in the clean water tank, so that the clean water enters the second connecting pipe 310 through the second one-way valve 311 and is discharged into the inner cavity of the cleaning box 11 through the high-pressure spray head 2202, thereby achieving the effect of replacing the water in the cleaning box 11. This process does not require stopping the flushing of the crushed residue, thereby increasing the cleaning efficiency.
