Technical Field
[0001] The utility model relates to the technical field of dust removal equipment, in particular to a novel dust removal device for agricultural waste crushing production. Background Art
[0002] Agricultural wastes are mostly substances such as rice husks and straws. At present, a large amount of dust will be generated during the processes of crushing, conveying, mixing, etc. of agricultural wastes, which not only causes a large amount of dust in the workshop, but also a large amount of dust exists at the position near the door outside the workshop, seriously affecting the workshop environment. Since agricultural wastes come from nature and are non-toxic, many enterprises do not pay much attention to this. Generally, industrial fans are used for exhaust, driving air circulation to take away the dust. Although this solves the dust problem in the workshop to a certain extent, long-term external exhaust will surely threaten the physical health of the staff in the workshop. In order to ensure the physical health of the staff, a few enterprises adopt the working method of equipping dust masks to enter the workshop. Although the problem of the impact of dust on health is solved, the subsequent problems such as dyspnea and summer sultriness are still not solved.
[0003] Ultimately, there is no good solution to the dust in the agricultural waste crushing workshop in the current technology. Therefore, dust removal in the agricultural waste crushing and processing production workshop is very important. Content of the Utility Model
[0004] Aiming at the deficiencies existing in the prior art, the utility model provides a novel dust removal device for agricultural waste crushing production, which is used to solve the problem that long-term direct exhaust of dust in the existing agricultural waste crushing and processing production workshop easily causes environmental pollution.
[0005] To solve the above technical problems, the utility model provides the following technical solutions:
[0006] A novel dust removal device for agricultural waste crushing production, including a dust removal box and a dust removal water tank fixedly connected to one side of the dust removal box. The dust removal box is connected to a dust exhaust pipe from a rice husk crusher. A dust receiving box inserted into the dust removal box is arranged at a position near the bottom of the surface of the dust removal box. A circulation groove is arranged on one side of the dust removal box corresponding to the dust removal water tank;
[0007] A spray box is fixedly connected to the top of the dust removal water tank near the circulation groove. A spray pipe is arranged in the spray box. A duckbill spray head is installed at the bottom of the spray pipe. The spray pipe is connected to a water pump through a connecting pipe. A water inlet pipe connecting to a water source is installed at the water inlet of the water pump;
[0008] The bottom of the dust removal water tank is inclined, and the height of the side of the bottom of the dust removal water tank close to the dust removal box is greater than the height of the side away from the dust removal box. A sludge pump is installed on the bottom of the inner wall of the dust removal water tank on the side away from the dust removal box. The sludge discharge pipe of the sludge pump extends to the outside of the dust removal water tank. A sewage discharge pipe and a drain pipe are also provided at a position on the surface of the dust removal water tank close to the sludge pump. The height of the drain pipe is greater than the height of the sewage discharge pipe.
[0009] Preferably, a connection hopper is installed between the dust discharge pipe and the dust removal box, and the diameter of the side of the connection hopper corresponding to the dust removal box is greater than the diameter of the side corresponding to the dust discharge pipe.
[0010] Preferably, a converging hopper is fixedly connected to the inner wall of the dust removal box above the dust collection box. The height of the connection hopper is greater than the height of the converging hopper and less than the height of the flow channel. A push-pull handle is also provided on the surface of the side of the dust collection box located outside the dust removal box.
[0011] Preferably, the flow channel is horizontally arranged, and a diversion channel is fixedly connected to the outer wall of the dust removal box at a position corresponding to the flow channel.
[0012] Preferably, the diversion channel is a flat channel arranged horizontally, and two to three flow channels and diversion channels are arranged in the vertical direction.
[0013] Preferably, the spray pipes are horizontally arranged and the number is not less than three. The spray pipes are parallel to the diversion channels, and the length of the spray pipes is greater than the length of the diversion channels.
[0014] Preferably, the duckbill nozzles are equidistantly arranged on the spray pipes, and the duckbill nozzles on adjacent two spray pipes are arranged in a staggered manner.
[0015] Preferably, the connecting pipe is connected to multiple spray pipes through a shunt pipe.
[0016] Preferably, an overflow water tank is arranged on the inner wall of the dust removal water tank on the side close to the sludge pump, and the drain pipe corresponds to the position of the overflow water tank.
[0017] Compared with the prior art, the present utility model has the following beneficial effects:
[0018] The utility model connects a dust exhaust pipe through an induced draft fan or an exhaust fan in the workshop, and conveys the air mixed with dust in the workshop into the dust removal box. The caliber of the dust exhaust pipe is smaller than that of the dust removal box, and the air flow rate is large. When the air mixed with dust enters the dust removal box, the pressure decreases and the flow rate also decreases. The dust can settle and enter the dust collection box for collection. At the same time, the air flows horizontally through the diversion groove into the dust removal water tank, and water mist is sprayed downward through the spray pipe and the duckbill nozzle. The dust adsorbs water droplets and the gravity increases, so it settles into the dust removal water tank. After the dust in the dust removal water tank precipitates and accumulates, it can be pumped out through the sludge pump for centralized treatment. The water in the dust removal water tank can also be conveyed to the sewage treatment workshop of the factory area through the drain pipe for centralized treatment. The dust in the agricultural waste crushing and processing workshop can be treated without pollution through simple equipment, avoiding direct external discharge and affecting the environment, thus solving the problem that the existing agricultural waste crushing and processing production workshop directly discharges dust for a long time, which easily causes environmental pollution.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Such as Figures 1 - 3As shown in the figure, the present utility model provides a technical solution: a novel dust removal device for agricultural waste crushing production, which includes a dust removal box 1 and a dust removal water tank 2 fixedly connected to one side of the dust removal box 1. The dust removal box 1 is connected to a dust discharge pipe 3. The dust discharge pipe 3 is used to connect the induced draft fan or exhaust fan in the agricultural waste crushing and processing production workshop to extract the air mixed with dust in the workshop and drive the air circulation at the same time. A connecting hopper 16 is installed between the dust discharge pipe 3 and the dust removal box 1, and the diameter of the connecting hopper 16 corresponding to the side of the dust removal box 1 is larger than the diameter corresponding to the side of the dust discharge pipe 3, which is used to increase the cross-section of air circulation, reduce the air flow rate, and help the dust in the air to settle in the dust removal box 1;
[0025] A dust receiving box 4 inserted into the dust removal box 1 is arranged at a position near the bottom of the surface of the dust removal box 1. A converging hopper 17 located above the dust receiving box 4 is fixedly connected to the inner wall of the dust removal box 1. The height of the connecting hopper 16 is greater than the height of the converging hopper 17 and less than the height of the flow channel 5. A push-pull handle 18 is also arranged on one side surface of the dust receiving box 4 located outside the dust removal box 1;
[0026] A flow channel 5 is arranged on one side of the dust removal box 1 corresponding to the dust removal water tank 2. The flow channel 5 is horizontally arranged. A diversion channel 19 is fixedly connected to the outer wall of the dust removal box 1 at a position corresponding to the flow channel 5. The diversion channel 19 is a horizontally arranged flat groove. Two to three flow channels 5 and diversion channels 19 are arranged in the vertical direction to horizontally guide the air flow and make it fully contact with the water sprayed downward, so that the dust is more likely to adsorb water droplets to increase gravity and settle;
[0027] A spray box 6 is fixedly connected to the top of the dust removal water tank 2 near the flow channel 5. A spray pipe 7 is arranged in the spray box 6. A duckbill nozzle 8 is installed at the bottom of the spray pipe 7. The spray pipe 7 is horizontally arranged and the number is not less than three. The spray pipe 7 is parallel to the diversion channel 19, and the length of the spray pipe 7 is greater than the length of the diversion channel 19. The duckbill nozzles 8 are equidistantly arranged on the spray pipe 7, and the duckbill nozzles 8 on two adjacent spray pipes 7 are arranged in a staggered manner. A connecting pipe 9 is connected to multiple spray pipes 7 through a shunt pipe 20. The spray pipe 7 is connected to a water pump 10 through the connecting pipe 9. A water inlet pipe 11 connecting to a water source is installed at the water inlet of the water pump 10. The water source can be ordinary industrial water or the secondary water discharged up to standard after the enterprise's own sewage treatment;
[0028] The bottom of the dust removal water tank 2 is inclined, and the height of the side of the bottom of the dust removal water tank 2 near the dust removal box 1 is greater than the height of the side away from the dust removal box 1, which is beneficial to the dust in the water to gather to the right side. A sludge pump 12 is installed on the bottom of the inner wall of the dust removal water tank 2 away from the dust removal box 1. The sludge discharge pipe 13 of the sludge pump 12 extends to the outside of the dust removal water tank 2. When the dust in the water gathers to a certain extent, it is pumped out through the sludge pump 12;
[0029] A sewage discharge pipe 14 and a drain pipe 15 are also provided at a position on the surface of the dust removal water tank 2 close to the sludge pump 12. The sewage discharge pipe 14 is used for draining water when the dust removal water tank 2 is regularly cleaned, and the drain pipe 15 is used for timely discharging excess water. The height of the drain pipe 15 is greater than that of the sewage discharge pipe 14. An overflow water tank 21 is provided on the inner wall of the dust removal water tank 2 on the side close to the sludge pump 12. The position of the drain pipe 15 corresponds to that of the overflow water tank 21. Dust precipitates in the water. Without affecting the normal operation of the sludge pump 12, the higher the height of the drain pipe 15, the less dust there is in the discharged water.
[0030] Working principle:
[0031] The dust suction pipe connected to the air inlet of the induced draft fan or exhaust fan in the workshop faces the vicinity of the feed inlet or discharge outlet of the crusher. The induced draft fan or exhaust fan is connected to the dust exhaust pipe. The dust exhaust pipe conveys the air mixed with dust in the workshop into the dust removal box. The diameter of the dust exhaust pipe is smaller than that of the dust removal box and the air flow rate is large. When the air mixed with dust enters the dust removal box, the pressure and the flow rate both decrease. The dust can settle and enter the dust collection box 4 for collection. At the same time, the air flows horizontally into the dust removal water tank through the diversion groove 19 and sprays water mist downward through the spray pipe 7 and the duckbill nozzle 8. The dust adsorbs the water droplets and the gravity increases, so it settles into the dust removal water tank. After the dust in the dust removal water tank precipitates and accumulates, it can be pumped out by the sludge pump 12 for centralized treatment. The water in the dust removal water tank can also be conveyed to the sewage treatment workshop in the factory area through the drain pipe 15 for centralized treatment. The dust in the agricultural waste crushing and processing workshop can be treated without pollution through simple equipment, avoiding direct external discharge and affecting the environment.
