Description

Technical Field

[0001] This utility model belongs to the field of plastic particle purification technology, specifically a screening and impurity removal device for recycled plastic modified particles. Background Technology

[0002] Modified recycled plastic granules are granular materials made from recycled and reprocessed waste plastics. Through modification treatments, their properties can be improved. For example, forming a thin film or coating on the surface of the recycled plastic granules can enhance their anti-aging, heat resistance, and corrosion resistance, making them a viable alternative to virgin plastics in the production of various products. The emergence of modified recycled plastic granules provides a new pathway for plastic recycling, helping to reduce dependence on limited natural resources and lessen the environmental burden. Furthermore, using recycled plastic granules to manufacture products can effectively reduce the demand for virgin plastics, lower the level of plastic pollution, contribute to the development of a circular economy, and slow down energy and resource consumption. With increasing global emphasis on environmental protection and sustainable development, modified recycled plastic granules have a broad market prospect.

[0003] The existing technology still has the following shortcomings:

[0004] 1. Existing recycled plastic modified granules are prone to dust and dirt, and traditional screening and impurity removal devices only screen plastic granules by vibration during operation, which can easily cause dust pollution and affect the environment and the health of operators.

[0005] 2. In addition, existing screening and impurity removal devices consume a lot of energy during operation, and the screens are not easy to replace, which is time-consuming and labor-intensive, affecting operational efficiency and economic benefits. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a screening and impurity removal device for modified recycled plastic particles, which solves the problems of poor safety, high energy consumption and inconvenient screen replacement in existing screening and impurity removal devices.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a servo motor is fixedly connected to the base plate, a support frame is fixedly connected to the top of the base plate, a cleaning chamber is fixedly connected to the top of the support frame, a cleaning assembly is provided inside the cleaning chamber, the cleaning assembly includes a grooved plate fixedly connected to the bottom of the cleaning chamber, an opening and closing plate is slidably connected to one side of the grooved plate, a water outlet pipe is connected to one side of the cleaning chamber, a valve is provided on the water outlet pipe, and a material discharge bin is connected to the bottom of the grooved plate.

[0008] As a further embodiment of this utility model: the output end of the servo motor is coaxially and fixedly connected to a first pulley, a stirring rod is rotatably connected to one side of the cleaning chamber, and a second pulley is fixedly connected to the end of the stirring rod near the servo motor.

[0009] As a further embodiment of this utility model: a shaft is fixedly connected to one side of the first pulley, and the shaft passes through one side of the support frame and is fixedly connected to the third pulley.

[0010] As a further embodiment of this utility model: two limiting frames are fixedly connected to the top of the support frame, and a drum screen is rotatably connected between the two limiting frames. The drum screen is composed of multiple screen cylinders.

[0011] As a further embodiment of this utility model: the drum screen is circumferentially fixedly connected to a fourth pulley, and the third and fourth pulleys are connected by a belt.

[0012] As a further embodiment of this utility model: a collection box is fixedly connected to the base plate, and multiple compartments are provided inside the collection box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model is designed with a cleaning component. Plastic granules and cleaning liquid are placed in the cleaning chamber. By controlling the rotation of the servo motor, the first pulley is driven to rotate. Under the action of the belt, the second pulley also rotates, which can drive the stirring rod to stir in the cleaning chamber, thus accelerating the cleaning. After the cleaning is completed, the wastewater can be discharged through the water pipe, and the material can be conveyed from the feeding hopper into the drum screen by pulling the opening and closing plate.

[0015] 2. This utility model incorporates a linkage component. Under the action of the shaft, pulley number one drives pulley number three to rotate.

[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0021] like Figures 1-3 As shown, this utility model provides a technical solution:

[0022] A base plate 1 is fixedly connected to a servo motor 2. A support frame 3 is fixedly connected to the top of the base plate 1. A cleaning chamber 4 is fixedly connected to the top of the support frame 3. A cleaning assembly is installed inside the cleaning chamber 4. The cleaning assembly includes a grooved plate 5 fixedly connected to the bottom of the cleaning chamber 4. An opening and closing plate 6 is slidably connected to one side of the grooved plate 5. A water outlet pipe 7 is connected to one side of the cleaning chamber 4. A valve is installed on the water outlet pipe. A material discharge bin 8 is connected to the bottom of the grooved plate 5. A first pulley 9 is coaxially fixedly connected to the output end of the servo motor 2. A stirring rod 10 is rotatably connected to one side of the cleaning chamber 4. A second pulley 11 is fixedly connected to the end of the stirring rod 10 near the servo motor 2. The first pulley 9 and the second pulley 11 are connected by a belt. Plastic granules and cleaning solution are placed in the cleaning chamber. Inside the cleaning chamber 4, the servo motor 2 is controlled to rotate, which drives the first pulley 9, which is coaxially fixed to its output end, to rotate. Under the action of the belt, the second pulley 11 also rotates, which can drive the stirring rod 10 to rotate in the cleaning chamber 4. The stirring accelerates the cleaning and removes dirt and dust. After the cleaning is completed, the valve is opened and the sewage is discharged through the water outlet pipe 7. Then, by pulling the opening and closing plate 6, the material can be conveyed from the feeding bin 8 into the drum screen 15, which ensures the cleanliness of the plastic particles and reduces dust. This reduces the adverse effects of dust on the operators and improves the impurity removal effect. The base plate 1 can accommodate the overall structure, and the support frame 3 can support the cleaning components and the limiting frame 14. The limiting frame 14 can support the drum screen 15 and limit the position of the drum screen 15.

[0023] A shaft 12 is fixedly connected to one side of the first pulley 9. The shaft 12 passes through one side of the support frame 3 and is fixedly connected to a third pulley 13. Two limiting frames 14 are fixedly connected to the top of the support frame 3. A drum screen 15 is rotatably connected between the two limiting frames 14. The drum screen 15 is composed of multiple screen cylinders. A fourth pulley 16 is fixedly connected to the circumference of the drum screen 15. The third pulley 13 and the fourth pulley 16 are connected by a belt. A collection box 17 is fixedly connected to the bottom plate 1. The collection box 17 is equipped with multiple partitions. A linkage component is provided. Under the action of the shaft 12, the first pulley 9 can... The belt drives the third pulley 13 to rotate, and under the transmission of the belt, the fourth pulley 16 also rotates, driving the drum screen 15 fixedly connected to it to rotate. The drum screen 15, through the combination of multiple screen cylinders with different apertures, can screen plastic particles, greatly reducing energy consumption. When the drum screen 15 is damaged, only the damaged part of the screen cylinder needs to be replaced, which is convenient for replacement and can reduce resource waste. The groove plate 5 can restrict the position of the opening and closing plate 6, and the through holes on the groove plate 5 can allow the material to be transported from the washing chamber 4 to the drum screen 15. The collection box 17 can collect the materials screened by different screen cylinders through the partition.

[0024] The working principle of this utility model is as follows:

[0025] Plastic granules and cleaning solution are placed in the cleaning chamber 4. The servo motor 2 is controlled to rotate, which drives the first pulley 9, which is coaxially fixed to its output end, to rotate. Under the action of the belt, the second pulley 11 also rotates, which drives the stirring rod 10 to rotate in the cleaning chamber 4. The stirring accelerates the cleaning process and removes dirt and dust. After the cleaning is completed, the valve is opened and the wastewater is discharged through the water outlet pipe 7. Then, the material can be conveyed from the feeding bin 8 into the drum screen 15 by pulling the opening and closing plate 6. This ensures the cleanliness of the plastic granules, reduces dust, reduces the adverse effects of dust on the operators, and improves the impurity removal effect.

[0026] A linkage assembly is installed. Under the action of shaft 12, pulley 9 can drive pulley 13 to rotate. Under the transmission of the belt, pulley 16 also rotates, driving the drum screen 15 fixedly connected to it to rotate. The drum screen 15 can screen plastic particles by combining multiple screen cylinders with different apertures, which greatly reduces energy consumption. When the drum screen 15 is damaged, only the damaged part of the screen cylinder needs to be replaced, which is convenient for replacement and can reduce resource waste.

[0027] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
