AI Technical Summary
[0002]目前,塑料粒子等颗粒类物料在生产、储存、运输过程中容易吸附混入灰尘等杂质,因此此类物料在使用前需要进行除尘,譬如公告号为CN219855511U的中国专利中就披露了一种塑料粒子的除尘装置,但是该除尘装置在将粉尘分离后无法对分离的粉尘进行有效的捕捉收集处理,导致部分粉尘会进入空气中影响生产环境并危害工作人员的健康
[0032] The above technical solution involves a feeding mechanism that transports materials to the material inlet of the dust separator. After entering the dust separator, the materials roll downwards due to the height difference. Simultaneously, gas drawn by the fan passes through the filter and enters the dust separator through the gas inlet. This gas carries away dust mixed in with the materials, thus achieving dust removal. The dust-removed materials are discharged from the material outlet, while the dust-laden gas is discharged into a cyclone separator. In the cyclone separator, a portion of the dust is carried to a collection bin at the bottom by the cyclone, while a small portion enters the dust collector with the airflow. The dust collector contains a dust filter element. As the gas passes through the filter element, the dust carried in the gas adheres to it. Clean gas then flows from the dust collector's outlet into the fan, achieving gas circulation. The above process not only separates dust from materials but also collects and treats the separated dust, thereby preventing dust from entering the air and avoiding its impact on the production environment and harm to personnel health.

[0035] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0036] like Figure 1 As shown, a dust separation device includes a dust separator 1, a feeding mechanism, a cyclone separator 2, a dust collector 3, a fan 4, and a filter 5;
[0037] The dust separator 1 has a material inlet 6, a material outlet 7, a gas inlet 8, and a gas outlet 9. The dust separator 1 is used to receive material from the material inlet 6 and make the material roll in the dust separator 1 and then discharge it from the material outlet 7. The dust separator 1 is also used to receive gas from the gas inlet 8 and let the gas carry away the dust mixed in the material and then discharge the dust-laden gas from the gas outlet 9.
[0038] The feeding mechanism is connected to the material inlet 6 of the dust separator 1. The air inlet of the cyclone separator 2 is connected to the gas outlet 9 of the dust separator 1. The air outlet of the cyclone separator 2 is connected to the air inlet of the dust collector 3. The air outlet of the dust collector 3 is connected to the inlet of the fan 4. The outlet of the fan 4 is connected to the inlet of the filter 5. The outlet of the filter 5 is connected to the gas inlet 8 of the dust separator 1. Specifically, the feeding mechanism is used to convey the material to the material inlet 6 of the dust separator 1. After entering the dust separator 1 from the material inlet 6, the material will roll to a lower position due to the height difference. At the same time, the gas drawn by the fan 4 passes through the filter 5 and enters the dust separator 1 from the gas inlet 8. After entering the dust separator 1, the gas can carry away the dust mixed in the material in the dust separator 1, thereby achieving dust removal from the material. The dust-removed material can be discharged from the material outlet 7, while the gas carrying dust can be discharged from the gas outlet 9 into the cyclone separator 2. In the cyclone separator 2, a portion of the dust is sent into the collection bucket 24 at the bottom of the cyclone separator 2 by the cyclone, and a small portion of the dust will enter the dust collector 3 with the airflow. The dust collector 3 is equipped with a dust removal filter element. After the gas in the dust collector 3 passes through the dust removal filter element, the dust carried in the gas adheres to the dust removal filter element. Then, the clean gas flows into the fan 4 from the outlet of the dust collector 3, thus realizing the circulation of gas. Through the above process, not only can dust in the material be separated and collected, but the separated dust can also be treated, thereby preventing dust from entering the air and avoiding dust from affecting the production environment and harming personnel health. More specifically, the filter 5 can filter out impurities in the gas blown by the fan 4, and the dust collector 3 has a back-blowing device 25, which is used to blow the dust attached to the dust removal filter element into the dust collection bin 26 below. The specific structures of the cyclone separator 2, dust collector 3, fan 4 and filter 5 are all prior art well known to those skilled in the art, and will not be described in detail in this embodiment.
[0039] like Figure 1 As shown, the feeding mechanism may include a hopper 10 and a screw feeder 11;
[0040] The silo 10 is used for storing materials;
[0041] The feed inlet of the screw feeder 11 is connected to the outlet at the bottom of the hopper 10, and the discharge outlet of the screw feeder 11 is connected to the material inlet 6 of the dust separator 1.
[0042] like Figure 1As shown, the feeding mechanism may further include a material receiver 12 disposed above the hopper 10. The inlet of the material receiver 12 is used to receive materials sent from the outside, and the outlet of the material receiver 12 is connected to the hopper 10. Specifically, after the material is conveyed to the material receiver 12, it falls from the outlet of the material receiver 12 into the hopper 10. The material in the hopper 10 enters the screw feeder 11, and then the screw feeder 11 can convey the material to the material inlet 6 of the dust separator 1, so that the material enters the dust separator 1. The material can be plastic particles. The specific structures of the material receiver 12 and the screw feeder 11 are existing technologies well known to those skilled in the art, and will not be described in detail in this embodiment.
[0043] like Figure 1 As shown, the dust separation device may further include an inlet air filter component and an outlet air filter component;
[0044] The inlet of the fan 4 is connected to the outlet of the dust collector 3 through the air inlet pipe 13;
[0045] The outlet of the fan 4 is connected to the inlet of the filter 5 through the air outlet pipe 14;
[0046] The air inlet duct 13 is provided with an air inlet 15 for receiving external gas, and the air inlet filter component is connected to the air inlet 15 and is used to filter the gas entering the air inlet duct 13 from the air inlet 15.
[0047] The air outlet duct 14 is provided with an air outlet for discharging the gas in the air outlet duct 14 to the outside. The air outlet filter component is connected to the air outlet and is used to filter the gas discharged from the air outlet.
[0048] like Figure 1As shown, the inlet air filtration component may include a first air filter element 16 and a first valve 17. One end of the first valve 17 is connected to the air inlet 15, and the other end of the first valve 17 is connected to the first air filter element 16. The outlet air filtration component may include a second air filter element 18 and a second valve. One end of the second valve is connected to the air outlet, and the other end of the second valve is connected to the second air filter element 18. Specifically, while the gas discharged from the outlet of the dust collector 3 is drawn into the fan 4, outside air also passes through the first air filter element 16 and the first valve 17 and enters the air inlet duct 13, where it is then drawn into the fan 4. Part of the gas discharged from the fan 4 passes through the filter 5 and enters the dust separator 1 through the gas inlet 8, while the other part passes through the second valve and the second air filter element 18 from the outlet and is discharged to the outside. When a customer needs to increase the output of material dust removal, the rotation speed of the screw feeder 11 can be increased, thereby increasing the amount of material entering the dust separator 1. Simultaneously, the opening of the first valve 17 needs to be increased to allow more outside air to enter the air inlet duct 13 and be drawn in by the fan 4. At the same time, the opening of the second valve needs to be decreased to allow more air blown by the fan 4 to pass through the filter 5 before entering the dust separator 1. This increases the airflow and velocity entering the dust separator 1, thus increasing the material dust removal output while maintaining the dust removal effect. Specifically, both the first valve 17 and the second valve can be manual ball valves.
[0049] Specifically, the dust separator 1 has an electrostatic eliminator for eliminating static electricity generated by material friction.
[0050] like Figure 1 As shown, the dust separator 1 may include a housing 19 and a plurality of guide vanes 20;
[0051] The guide plate 20 is installed in the housing 19 and is divided in the housing 19 to form an air inlet chamber 21 and a material guiding channel 22;
[0052] The material inlet 6 is located at the top of the outer shell 19 and communicates with the upper end of the material guiding channel 22, and the material outlet 7 is located at the bottom of the outer shell 19 and communicates with the lower end of the material guiding channel 22.
[0053] The gas outlet 9 is located at the upper end of the outer casing 19 and communicates with the material guide channel 22;
[0054] The gas inlet 8 is located on the outer casing 19 and communicates with the air inlet cavity 21;
[0055] The guide plate 20 is provided with air holes for gas to pass through, and the air inlet chamber 21 is connected to the material guide channel 22 through the air holes. Specifically, the material entering from the material inlet 6 will roll along the material guide channel 22 and then be discharged from the material outlet 7. At the same time, the gas blown out by the blower 4 will be filtered by the filter 5 and enter the air inlet chamber 21 from the gas inlet 8. Then the gas will pass through the air holes and enter the material guide channel 22. In the material guide channel 22, the gas will carry away the dust mixed in the material, thereby achieving dust removal from the material. Then the gas carrying dust will be discharged from the gas outlet 9 into the cyclone separator 2.
[0056] like Figure 1 As shown, the material guide channel 22 extends in a wave-like shape in the vertical direction, and the outer shell 19 is also connected to a baffle plate 23 located on one side of the material inlet 6.
[0057] In this embodiment, the fan 4 can be a centrifugal fan.
[0058] In summary, the feeding mechanism is used to convey materials to the material inlet 6 of the dust separator 1. After entering the dust separator 1 from the material inlet 6, the materials will roll downhill due to the height difference. At the same time, the gas drawn by the fan 4 passes through the filter 5 and enters the dust separator 1 from the gas inlet 8. After entering the dust separator 1, the gas can carry away the dust mixed in with the materials in the dust separator 1, thereby achieving dust removal. The dust-removed materials can be discharged from the material outlet 7, while the gas carrying dust can be discharged from the gas outlet 9 into the cyclone separator 2. In the cyclone separator 2, a portion of the dust can be sent into the collection bucket 24 at the bottom of the cyclone separator 2 by the cyclone, and a small portion of the dust will enter the dust collector 3 with the airflow. The dust collector 3 is equipped with a dust removal filter element. After the gas in the dust collector 3 passes through the filter element, the dust carried in the gas adheres to the filter element. Then, the clean gas flows from the outlet of the dust collector 3 into the fan 4, thus achieving gas circulation. This process not only separates dust from materials but also collects and treats the separated dust, preventing it from entering the air and thus avoiding its impact on the production environment and the health of personnel.
