Description

Technical Field

[0001] The utility model relates to the technical field of industrial solid waste treatment, in particular to an industrial solid waste shredder. Background Art

[0002] An industrial solid waste shredder is a device specifically used for treating industrial solid waste. Its core working principle is to push the solid waste onto the rotating blades, and utilize the high-speed rotation of the blades to achieve the fragmentation of the waste. This process usually involves an electric motor driving a speed reducer, and then transmitting the torque to the moving blades of the shredder through the cutter roller shaft. The hooks of the moving blades hook the material and tear it downwards, while the blades of the counter-roll cut the material like scissors. Industrial solid waste shredders are widely used in the treatment of various solid wastes, including plastics, wood, headstock materials, braid materials, iron sheet cylinders, tires, aluminum alloys, frozen meat, etc. For example, an industrial solid waste shredder with the publication number CN219849966U specifically discloses a working box body. Inside the working box body, there is a shredding cutter roller. One end of the shredding cutter roller passes through the working box body and is in transmission connection with the output end of the working motor. The upper end of the working box body is fixedly connected with a feeding box, and the upper end of the feeding box is fixedly connected with a waste gas detection component. The waste gas detection component includes a waste gas detection box body, a gas detector, a gas detection pipeline, a processor, and a ventilation pipeline. On one side of the waste gas detection box body, there is a fixedly arranged gas detector and a processor. The detection end of the gas detector is fixedly communicated with the gas detection pipeline. The existing industrial solid waste shredders cannot control the amount of solid waste during feeding. When the amount of solid waste inside the industrial solid waste shredder exceeds the limit, too much solid waste may hinder the effective rotation of the blades and the smooth transmission of the material, and the excessive solid waste may lead to a reduction in the processing efficiency of the shredder. Therefore, we propose an industrial solid waste shredder. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides the following technical solutions:

[0005] The utility model relates to an industrial solid waste shredder, which comprises a housing. Two spaced roller shafts are rotatably installed in the housing, and crushing rollers are fixedly installed on the roller shafts. A driving mechanism for driving the two crushing rollers to rotate is installed on the housing, and the driving mechanism is connected to the roller shafts. A diversion channel is fixedly installed in the housing. The diversion channel is funnel-shaped and is located above the gap between the two crushing rollers. Two spaced baffles are arranged in the diversion channel. A guide sleeve is arranged between the two baffles. Side rods are fixedly installed on both sides of the guide sleeve, and the ends of the side rods are fixedly connected to the inner side of the diversion channel. Movable rods that can slide are inserted into both ends of the guide sleeve, and the ends of the movable rods are fixedly connected to the baffles. Springs are sleeved on the movable rods, and the two ends of the springs are respectively fixedly connected to the guide sleeve and the baffle.

[0010] As a preferred technical solution of the utility model, crushing teeth are fixedly installed on both sides inside the housing.

[0011] The beneficial effects of the utility model are:

[0012] This industrial solid waste shredder uses a baffle to block the waste from the lower port of the diversion channel. When the electromagnet is energized, it can apply an adsorption force to the movable rods on both sides. The movable rods and the baffle move synchronously, expanding the lower port of the side cavity of the diversion channel, so that the waste can be discharged from the lower port of the diversion channel. After a period of time, the electromagnet is de-energized, and the elastic force of the spring drives the baffle to reset, continuing to block the waste from being discharged from the lower port of the diversion channel, thus achieving intermittent waste discharge with controllable waste volume.

[0013] This industrial solid waste shredder sucks the air in the pipeline through a suction pump. The inner cavities of the pipeline, roller shaft, and crushing roller are in a connected state. By sucking the air in the inner cavity of the crushing roller, a negative pressure airflow can be generated at the air intake groove, sucking the dust in the housing. The air containing dust is introduced into the water tank, which is filled with water, so that the dust is adsorbed by the water in the water tank, reducing the dust in the housing and effectively suppressing the dust phenomenon near the shredder.

Detailed Embodiments

[0021] The following describes the preferred embodiments of the present invention with reference to the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0022] Embodiment: As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 shown, a kind of industrial solid waste shredder of the utility model includes a housing 1. Two spaced roller shafts 2 are rotatably installed in the housing 1. Crushing rollers 3 are fixedly installed on the roller shafts 2. A driving mechanism for driving the two crushing rollers 3 to rotate is installed on the housing 1. The driving mechanism is connected to the roller shafts 2. A diversion channel 4 is fixedly installed in the housing 1. The diversion channel 4 is arranged in a funnel shape. The diversion channel 4 is located above the gap between the two crushing rollers 3. Two spaced baffles 5 are arranged in the diversion channel 4. A guide sleeve 6 is arranged between the two baffles 5. Side rods 7 are fixedly installed on both sides of the guide sleeve 6. The ends of the side rods 7 are fixedly connected to the inner side of the diversion channel 4. Movable rods 8 that can slide are inserted into both ends of the guide sleeve 6. The ends of the movable rods 8 are fixedly connected to the baffles 5. Springs 9 are sleeved on the movable rods 8. Both ends of the springs 9 are respectively fixedly connected to the guide sleeve 6 and the baffles 5. The movable rods 8 are magnets. An electromagnet 10 is fixedly installed in the guide sleeve 6.

[0023] By placing the waste materials at the positions of the two side cavities in the diversion channel 4, and the waste materials are located on the side of the baffle 5. The volume of the waste materials is larger than the lower port of the diversion channel 4. The baffle 5 can block the waste materials from flowing out of the lower port of the diversion channel 4. The electromagnet 10 is energized regularly. When the electromagnet 10 is energized, it can apply an adsorption force to the two side movable rods 8. The movable rods 8 and the baffle 5 move synchronously, and the spring 9 contracts, which can expand the lower port of the side cavity of the diversion channel 4. Thus, the waste materials can be discharged from the lower port of the diversion channel 4. After a period of time, the electromagnet 10 is powered off, and the elastic force of the spring 9 drives the baffle 5 to reset, which can continue to block the waste materials from flowing out of the lower port of the diversion channel 4. Thus, intermittent discharge of waste materials and controllable waste material quantity are realized.

[0024] Among them, support legs are fixedly installed at the four corners of the bottom of the housing 1, and anti-slip pads are arranged at the bottoms of the support legs. The lower end of the housing 1 is open, and diversion inclined surfaces 11 are arranged at the lower end inside the housing 1. The driving mechanism includes two transmission wheels 12. The transmission wheels 12 are respectively fixedly installed at the ends of the roller shafts 2. The two transmission wheels 12 are meshed. A motor 13 is fixedly installed outside the housing 1. The output shaft of the motor 13 is fixedly connected to one of the roller shafts 2.

[0025] The waste materials fall between the two crushing rollers 3. By driving one of the roller shafts 2 to rotate through the motor 13, the roller shaft 2 is connected to the crushing roller 3 and rotates synchronously. Then, through the transmission of the two transmission wheels 12, the two crushing rollers 3 can be driven to rotate synchronously and in opposite directions, and the waste materials between the two crushing rollers 3 can be shredded.

[0026] Among them, both the roller shaft 2 and the crushing roller 3 are hollow inside. The inner cavities of the roller shaft 2 and the crushing roller 3 are in a communicating state. A pipeline 14 is fixedly installed on the housing 1, and the pipeline 14 communicates with the inner cavities of the two roller shafts 2. The pipeline 14 is rotatably installed inside the roller shaft 2. A suction pump 15 is fixedly installed on the housing 1, and the intake pipe of the suction pump 15 communicates with the pipeline 14. A plurality of uniformly distributed air intake grooves 16 are formed on the surface of the crushing roller 3. A water tank 17 is fixedly installed on the housing 1, and the exhaust pipe of the suction pump 15 communicates with the water tank 17. Crushing teeth 18 are fixedly installed on both sides inside the housing 1.

[0027] By means of the suction pump 15 sucking the air in the pipeline 14, the inner cavities of the pipeline 14, the roller shaft 2, and the crushing roller 3 are in a communicating state. Thus, the air in the inner cavity of the crushing roller 3 is sucked, and a negative pressure air flow can be generated at the air intake grooves 16, thereby sucking the dust in the housing 1. The air containing dust is introduced into the water tank 17, and water is contained in the water tank 17. Thus, the dust is adsorbed by the water in the water tank 17, the dust in the housing 1 can be reduced, and the phenomenon of dust near the shredder can be effectively suppressed.

[0028] Working principle: The waste material is placed at the positions of the two side cavities in the diversion channel 4, and the waste material is located on the side of the baffle 5. The volume of the waste material is larger than the lower port of the diversion channel 4. The baffle 5 can block the waste material from the lower port of the diversion channel 4. The electromagnet 10 is energized regularly. When the electromagnet 10 is energized, an adsorption force can be applied to the two side movable rods 8. The movable rods 8 and the baffle 5 move synchronously, and the spring 9 contracts, so that the lower port of the side cavity of the diversion channel 4 can be enlarged. Thus, the waste material can be discharged from the lower port of the diversion channel 4. After a period of time, the electromagnet 10 is powered off, and the elastic force of the spring 9 drives the baffle 5 to reset, and the waste material can be continuously blocked from being discharged from the lower port of the diversion channel 4, thereby realizing the intermittent discharge of the waste material and the controllable amount of the waste material.

[0029] The waste material falls between the two crushing rollers 3. By driving the roller shaft 2 on one side to rotate through the motor 13, the roller shaft 2 and the crushing roller 3 are connected and rotate synchronously. Then, through the transmission of the two transmission wheels 12, the two crushing rollers 3 can be driven to rotate synchronously and in opposite directions, and the waste material between the two crushing rollers 3 can be shredded. By means of the suction pump 15 sucking the air in the pipeline 14, the inner cavities of the pipeline 14, the roller shaft 2, and the crushing roller 3 are in a communicating state. Thus, the air in the inner cavity of the crushing roller 3 is sucked, and a negative pressure air flow can be generated at the air intake grooves 16, thereby sucking the dust in the housing 1. The air containing dust is introduced into the water tank 17, and water is contained in the water tank 17. Thus, the dust is adsorbed by the water in the water tank 17, the dust in the housing 1 can be reduced, and the phenomenon of dust near the shredder can be effectively suppressed.
