Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a plastic granule processing device that can quickly remove impurities. Background Technology

[0002] Plastic granules, also known as plastic pellets, are the basic raw materials in the production of plastic products. They are usually composed of polymers and other additives and exist in granular form. These granules have a certain degree of fluidity and solubility, making them easy to use in different plastic processing technologies.

[0003] Due to their diverse physical and chemical properties, plastic granules have wide applications in many industries. For example, in daily life, plastic granules can be used to manufacture various household items and plastic products such as plastic bags, buckets, basins, toys, furniture, and stationery. In the clothing industry, they can be used to manufacture clothing, ties, buttons, and zippers. In building materials, plastic granules can be used to manufacture building components, plastic doors and windows, and mortar buckets. Furthermore, plastic granules are also widely used in the electrical and telecommunications industries.

[0004] During the processing of plastic granules, impurities tend to adhere to their surface, necessitating impurity removal to ensure the quality of subsequent plastic processing. Existing plastic granule processing equipment typically only uses a spray nozzle during screening to remove impurities, neglecting to directly brush the surface-adhered impurities. This results in insufficient cleaning, leaving unremoved impurities. Furthermore, the failure to promptly separate and remove these impurities leads to screen blockage by lightweight impurities mixed in with the plastic granules, impacting screening efficiency and impurity removal speed. Utility Model Content

[0005] To address the technical problem that most plastic granule removal processes only use spraying pipes during screening, without contact brushing to remove impurities adhering to the granule surface, resulting in insufficient cleaning and incomplete removal of impurities, and the failure to promptly separate the removed impurities, leading to clogging of the screen and affecting screening efficiency and removal speed, this invention provides a plastic granule processing device for rapid impurity removal.

[0006] A plastic granule processing device for rapid impurity removal includes an impurity removal box, a through groove on the side wall of the impurity removal box, a filter box outside the through groove, a filter layer inside the filter box, several nozzles connected to the filter box on the top wall of the impurity removal box, a reciprocating screw below the nozzles, an impurity removal screen threaded to the outer circumference of the reciprocating screw, an inclined partition below the impurity removal screen, a flow port at the inclined end of the partition, a washing roller rotatably mounted above the partition, and a vibrating screen inclined below the partition.

[0007] More preferably, an observation window is provided on the side wall of the impurity removal box at the same height as the through channel, and the height of the observation window is greater than the height of the through channel. A support column is provided at the bottom of the impurity removal box, and it is a funnel structure. A sewage pipe is provided at the bottom of the funnel. A discharge pipe is provided at the inclined end of the vibrating screen. Solenoid valves are provided inside the flow port, the sewage pipe, and the discharge pipe.

[0008] More preferably, a feed hopper and several nozzles are provided through the top wall of the impurity removal box. The water inlets of the nozzles are all connected to the conveying pipe. A water pump is installed inside the conveying pipe. The bottom end of the conveying pipe is connected to the inside of the filter box below the filter layer. The filter layer includes a filter screen and an activated carbon adsorption layer arranged sequentially from top to bottom.

[0009] More preferably, two motors are mounted on the outer wall of the impurity removal box via a mounting bracket. The output shaft of one of the motors is fixedly connected to a reciprocating lead screw. A guide groove parallel to the reciprocating lead screw is provided on the inner wall of the impurity removal box. The outer circumference of the reciprocating lead screw thread is threadedly connected to one end of a connecting rod. The other end of the connecting rod is slidably mounted on the guide groove. The impurity removal screen is fixedly mounted on the bottom wall of the connecting rod, and the bottom end of the impurity removal screen is lower than the bottom end of the through groove.

[0010] More preferably, the scrubbing roller includes a rotating shaft, which is mounted on the output end of another motor. Several stirring rods are fixedly mounted on the outer wall of the rotating shaft, and a brush head is fixedly mounted on the other end of each stirring rod. The inclination arc of the end of the brush head is consistent with the inclination arc of the partition.

[0011] More preferably, the inner sidewall of the impurity removal box is provided with several support blocks, the top wall of the support blocks is fixedly provided with springs, the bottom wall of the vibrating screen is fixedly connected to the top of the springs, and the bottom wall of the vibrating screen is provided with a vibrating motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the plastic particles falling into the partition are sprayed and washed using a nozzle, while a rotating brush roller is used to brush the surface of the plastic particles. Spraying and brushing are carried out simultaneously to achieve a more thorough cleaning. As water overflows into the channel during the spraying process, it drives the impurity removal screen to overflow the floating light impurities along the channel onto the filter screen. Then, the flow port is opened, allowing the plastic particles to fall into the vibrating screen below along with the water flow. Impurities mixed in the water and excessively small plastic particles fall down along the vibrating screen and are discharged from the drain pipe. The plastic particles that meet the particle size requirements are discharged along the discharge pipe, avoiding the blockage of the vibrating screen by light impurities not being cleaned in time. Moreover, the overflowing water can be reused after filtration. Attached Figure Description

[0023] A plastic granule processing device for rapid impurity removal includes an impurity removal box 1. A channel 2 is provided on the side wall of the impurity removal box 1. An observation window 12 is provided at the same height as the channel 2 on the side wall of the impurity removal box 1, with the observation window 12 being higher than the height of the channel 2. This allows observation of the impurity removal mesh 7's process of gathering and pushing light impurities, as well as the floating of light impurities. A support column is provided at the bottom of the impurity removal box 1 to support the entire device. The bottom of the impurity removal box 1 has a funnel structure, with a drain pipe 13 at the bottom of the funnel. A solenoid valve 15 is installed inside the drain pipe 13. Opening the solenoid valve 15 allows wastewater mixed with impurities and unscreened plastic granules to be discharged outside the device.

[0024] A filter box 3 is installed on the outside of the channel 2. The filter box 3 has an opening at the top. The filter layer 4 is installed inside the filter box 3. The filter layer 4 includes a filter screen 19 and an activated carbon adsorption layer 20 arranged from top to bottom. Light impurities overflowing from the channel 2 enter the filter box 3 with the water flow. The light impurities are filtered and blocked by the filter screen 19, while other impurities are adsorbed by the activated carbon adsorption layer 20 below. The filtered light impurities can be cleaned periodically through the top opening of the filter box 3.

[0025] The top wall of the impurity removal box 1 is equipped with several nozzles 5 that communicate with and are connected to the filter box 3. A feed hopper 16 and several nozzles 5 are installed through the top wall of the impurity removal box 1. The water inlets of the nozzles 5 are all connected to the conveying pipe 17. A water pump 18 is installed inside the conveying pipe 17. The bottom end of the conveying pipe 17 is connected to the inside of the filter box 3 located below the filter layer 4.

[0026] When the water pump 18 is started, the filtered water source can be transported from the bottom of the filter box 3 through the delivery pipe 17 to several nozzles 5, and the water sprayed out by the nozzles 5 can wash the plastic particles below.

[0027] A reciprocating screw 6 is installed below the nozzle 5. A cleaning screen 7 is threadedly connected to the outer circumference of the reciprocating screw 6. Two motors 21 are installed on the outer wall of the cleaning box 1 via a mounting bracket. The output shaft of one of the motors 21 is fixedly connected to the reciprocating screw 6. A guide groove 22 parallel to the reciprocating screw 6 is provided on the inner wall of the cleaning box 1. One end of the connecting rod 23 is threadedly connected to the outer circumference of the reciprocating screw 6. The other end of the connecting rod 23 is slidably mounted on the guide groove 22. The cleaning screen 7 is fixedly mounted on the bottom wall of the connecting rod 23. The bottom end of the cleaning screen 7 is lower than the bottom end of the through groove 2.

[0028] When the motor 21 is started, it can drive the reciprocating screw 6 to rotate, which in turn drives one end of the connecting rod 23 to move left and right, while the other end also moves left and right along the guide groove 22. This allows the impurity removal screen 7 to move left and right, collecting light impurities on the water surface and bringing them to the through groove 2. The light impurities then gather near the through groove 2 and overflow into the filter box 3 with the water flow for filtration.

[0029] A partition 8 is inclinedly arranged below the impurity removal screen 7, and a brush roller 10 is rotatably arranged above the partition 8. The brush roller 10 includes a rotating shaft 24, which is arranged on the output end of another motor 21. Several stirring rods 25 are fixedly arranged on the outer wall of the rotating shaft 24, and a brush head 26 is fixedly arranged at the other end of the stirring rod 25. The inclination arc of the end of the brush head 26 is consistent with the inclination arc of the partition 8.

[0030] While the plastic granules are being sprayed and washed, the motor 21 can be started to drive the rotating shaft 24 to rotate, which in turn drives the stirring rod 25 and the brush head 26 to rotate and brush the plastic granules on the partition 8. The rotation of the stirring rod 25 can also prevent the plastic granules from accumulating and make contact brushing of the surface of the plastic granules, so that the cleaning is more thorough and cleaner. Since the inclined end of the partition 8 is provided with a flow port 9, and a solenoid valve 15 is provided inside the flow port 9, when the solenoid valve 15 is opened, the cleaned plastic granules flow from the flow port 9 into the vibrating screen 11 below.

[0031] A vibrating screen 11 is inclinedly installed below the partition 8. The vibrating screen 11 is a filter screen with internal pores. Several support blocks 27 are installed on the inner side wall of the impurity removal box 1. Springs 28 are fixedly installed on the top wall of the support blocks 27. The bottom wall of the vibrating screen 11 is fixedly connected to the top of the springs 28. A vibrating motor 29 is installed on the bottom wall of the vibrating screen 11. When the vibrating motor 29 is started, the vibrating screen 11 vibrates under the elastic action of the springs 28, filtering water and mixed impurities, plastic particles that have not passed the screening, etc., to the bottom of the vibrating screen 11, and finally discharged from the drain pipe 13.

[0032] The inclined end of the vibrating screen 11 is provided with a discharge pipe 14, and a solenoid valve 15 is provided inside the discharge pipe 14. When the solenoid valve 15 is opened, plastic particles that meet the screening particle size are discharged from the discharge pipe 14.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
