Description

Technical Field

[0001] This utility model relates to the technical field of plastic crushing equipment, specifically to a dustproof and noise-reducing high-power plastic crusher. Background Technology

[0002] Crushers are commonly used in many industries, such as plastic recycling and chemical raw material processing, to break large materials into particles of suitable size for subsequent processing or reuse. However, traditional crushers have several problems in actual use. Regarding noise, the intense collisions and friction between the material and the crushing rollers, as well as the aerodynamic noise generated by the high-speed rotation of the rollers, create significant noise levels during operation. This noise can damage the hearing of operators, and prolonged exposure to high-noise environments can lead to dizziness, insomnia, and other health problems. Regarding dust, the fine dust generated during crushing is raised in large quantities and escapes from the crusher's feed inlet and other parts, permeating the work area. Inhaling this dust can harm the respiratory system, causing coughing, asthma, and other illnesses. Furthermore, dust adheres to the equipment surface, affecting normal operation and maintenance, increasing equipment failure rates, and reducing equipment lifespan. Utility Model Content

[0029] Example 1:

[0030] like Figures 1 to 5 As shown, this embodiment provides a dustproof and noise-reducing high-power plastic crusher, including a crusher 1. The base 101 of the crusher 1 is placed horizontally on the working site, and a crushing chamber 105 is fixedly connected to its upper surface. A crushing cutter roller 106 is rotatably installed inside the crushing chamber 105. A motor 102 is fixed to the front side of the base 101. The output shaft of the motor 102 and the right end of the crushing cutter roller 106 that passes through the outside of the crushing chamber 105 are both fixedly connected to synchronous pulleys 104. A synchronous belt is set between the two synchronous pulleys 104 to realize power transmission. A feeding trough 103 is fixedly connected to the bottom feeding port of the crushing chamber 105.

[0031] A noise reduction mechanism 2 is installed at the feed port of the crusher 1. Specifically, a feed chute 201 is fixed to the upper port of the crushing chamber 105. The upper surface of the front port of the feed chute 201 is hinged to a door 202. A layer of sound insulation cotton board 203 is adhered and fixed to the front end face of the door 202 with adhesive. A sealing strip is adhered to the side of the door 202 near the front port of the feed chute 201 with adhesive. A handle 204 is fixedly connected to the front side wall of the sound insulation cotton board 203. The handle 204 facilitates opening and closing of the door 202.

[0032] An arched frame 4 is fixedly connected to the rear side wall of the crusher 1. The front end face of the arched frame 4 is fixedly connected to the rear end face of the base 101, and the rear surface is in contact with the wall surface. A crushing dust prevention mechanism 3 is set in the inner cavity of the arched frame 4. A bracket 302 is fixed to the side wall of the blower 301. The side wall of the bracket 302 is fixed to the top side wall of the inner cavity of the arched frame 4 by bolts. An air collection tank 303 is fixed to the blower port of the blower 301. A conveying air pipe 304 is connected through the side wall of the air collection tank 303. The end of the conveying air pipe 304 is connected to a horizontal pipe 306 arranged horizontally at the top of the inner cavity of the feeding trough 201. Multiple through holes are opened at the top of the horizontal pipe 306, and a row of branch pipes 305 are fixed through it. A water tank 308 is installed on the side of the crusher 1. A bent pipe 307 is fixed to the top surface of the feeding trough 201. The end of the bent pipe 307 is submerged in the water tank 308. The inner cavity of the water tank 308 is filled with filtered water.

[0033] During operation, plastic materials are placed into the feeding trough 201, the hatch 202 is closed, the motor 102 is started to drive the crushing roller 106 to rotate and crush the materials, and at the same time the blower 301 is started. The airflow enters the upper layer of the inner cavity of the feeding trough 201 through the air collection tank 303, the conveying air pipe 304, the horizontal pipe 306 and the branch pipe 305, and carries the flying dust through the bend pipe 307 into the water tank 308 to be filtered and cleaned.

[0034] During actual installation, the position of the arched frame 4 can be adjusted according to the layout of the work site to better fit the wall surface and enhance stability.

[0035] When crushing plastic materials of different specifications, the speed of the motor 102 can be adjusted appropriately to meet the crushing requirements of different materials. For plastic materials of different hardness, crushing rollers 106 with different tooth profiles can be replaced to improve crushing efficiency and effect.

[0036] For some plastic materials containing impurities, a simple screen can be set at the front end of the feeding trough 201 to perform preliminary screening of the material, remove larger impurities, and prevent impurities from entering the crushing chamber 105 and damaging the crushing roller 106.

[0037] For some plastic materials that are prone to static electricity, an anti-static coating can be applied to the inner wall of the feeding trough 201 to reduce the amount of dust adsorbed on the inner wall of the feeding trough 201 due to static electricity.

[0038] After the filtered water in pool 308 has been used for a period of time, it should be replaced regularly to ensure effective filtration and cleaning of dust. During the crushing process, if wear or aging is found on the sealing strip of hatch 202, replace it with a new one in time to ensure sound insulation and sealing performance.

[0039] During the operation of the crushing and dust control mechanism 3, the wind speed of the blower 301 can be adjusted according to the dust level in the feeding trough 201 to achieve the best dust control effect. After the sound insulation cotton board 203 has been used for a period of time, a lot of dust will be absorbed on its surface, affecting the sound insulation effect. The sound insulation cotton board 203 can be removed for cleaning or replacement.

[0040] Based on the above-described preferred technical solution, the workflow of this technical solution is explained as follows:

[0041] When using this high-powered plastic crusher, the plastic material to be crushed is first placed in the feeding trough 201 of the crushing and noise reduction mechanism 2 of the crusher 1. Then, the motor 102 is started, and the output shaft of the motor 102 rotates, driving the synchronous pulley 104 fixed on it to rotate. Since a synchronous belt is provided between the synchronous pulley 104 on the output shaft of the motor 102 and the synchronous pulley 104 fixed at the right end of the crushing roller 106 that passes through the outside of the crushing chamber 105, the crushing roller 106 will rotate under the transmission of the synchronous belt. At this time, the crushing chamber 105 begins to crush the plastic material falling into the feeding trough 201. The crushed material is discharged from the feeding trough 103 fixed at the bottom feeding port of the crushing chamber 105. The sound insulation cotton board 203 fixed by adhesive on the front end face of the door 202 and the sealing strip attached to the side of the door 202 near the front port of the feeding trough 201 work together to effectively reduce the transmission of noise during the crushing process.

[0042] During the crushing process, the blower 301 in the crushing dust control mechanism 3 is started. The blower 301 generates airflow, which enters the air collection tank 303 fixed at its blower port. The airflow is then transported through the conveying air pipe 304 connected through the side wall of the air collection tank 303 to the horizontal pipe 306 arranged at the top of the inner cavity of the feeding trough 201. The top of the horizontal pipe 306 has multiple through holes and a row of branch pipes 305 are fixed through it. The airflow is ejected through the branch pipes 305, which carries the dust flying in the upper layer of the inner cavity of the feeding trough 201. The dust enters the bent pipe 307 fixed on the top surface of the feeding trough 201 with the airflow. The end port of the bent pipe 307 is submerged in the water pool 308 installed on the side of the crusher 1. The inner cavity of the water pool 308 is filled with filtered water. After the dust enters the water pool 308, it is filtered and cleaned by the filtered water.

[0043] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
