[0001] This utility model relates to the technical field of material crushing equipment, specifically to a high-efficiency and environmentally friendly dust-free crushing device. Background Technology

[0002] In modern large-scale livestock farming, feed grinding is a key pretreatment process, and the performance of the equipment directly affects feed quality and farming efficiency. Currently, commonly used feed grinding devices in livestock farming face the following unresolved technical bottlenecks in practical applications:

[0003] Traditional crushing equipment often adopts an open or semi-open structure, which generates a large amount of dust and debris when crushing raw materials such as grains, straw, and soybean meal. This dust and debris not only pollute the working environment and reduce visibility in the workshop, but may also cause respiratory diseases in workers.

[0004] Therefore, there is an urgent need for a highly efficient and environmentally friendly dust-free pulverizing device to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0005] In view of this, the present invention proposes a highly efficient and environmentally friendly dust-free pulverizing device, which aims to solve the problems existing in the prior art.

[0006] This utility model provides a high-efficiency and environmentally friendly dust-free pulverizing device, including: a pulverizing box, a feed inlet at the upper end of the pulverizing box, a discharge pipe at the lower end of the pulverizing box, and a dust collection box on one side of the pulverizing box;

[0007] The upper end of the crushing box is provided with a first annular dust collection box, which is located above the feed inlet. The upper end of the first annular dust collection box is provided with a detachable feeding pipe. The inner side of the first annular dust collection box is provided with multiple first suction holes. One side of the first annular dust collection box is provided with a first transfer pipe. The dust collection box is provided with a placement slot, and a detachable filter frame is provided in the placement slot. The top of the filter frame is provided with a top plate, which is fixed to the upper end of the dust collection box. The outer side of the dust collection box is provided with a negative pressure fan, and the suction end of the negative pressure fan is connected to the filter frame. The first transfer pipe is connected to the placement slot through a first conduit.

[0008] To facilitate the assembly of the feeding tube onto the first annular dust collection box, the present invention includes an improvement whereby the top of the first annular dust collection box is provided with a threaded groove, and the bottom end of the feeding tube is inserted into the threaded groove and threadedly connected to it.

[0009] To facilitate the removal of the filter frame from the placement slot, the present invention includes the following improvement: the top plate is fixed to the upper end of the dust collection box by screws, and a sealing ring is provided between the top plate and the dust collection box.

[0010] Furthermore, an improvement of this utility model is that the suction end of the negative pressure fan is provided with a suction pipe that is inserted into the dust collection box and communicates with the placement slot.

[0011] To reduce the dust generated during material discharge, the present invention includes the following improvements: the bottom end of the discharge pipe is provided with an annular limiting plate and a second annular dust collection box. The second annular dust collection box is penetrated by the discharge pipe and fixed to the lower end of the annular limiting plate. The lower end of the second annular dust collection box is provided with multiple second suction holes. A second adapter pipe is provided on one side of the annular limiting plate. The second adapter pipe is connected to the placement groove through a second conduit. The second annular dust collection box is adhered to the lower end of the annular limiting plate.

[0012] Furthermore, the improvements of this utility model include that both the first conduit and the second conduit are made of rubber hoses, and both the first annular dust collection box and the second annular dust collection box are made of metal.

[0013] Compared with the prior art, the beneficial effects of this utility model are that the first and second annular dust collection boxes work together to form a double protective net above the feed inlet and below the discharge outlet, which is like putting a "dust mask" on the crushing operation, firmly locking the dust inside the equipment and effectively preventing the dust from escaping into the external environment. Whether it is the fine dust flying during grain crushing or the larger flying debris generated by straw crushing, it can be captured and collected in time, which greatly reduces the dust concentration in the operating workshop, improves the working environment of workers, reduces the harm of dust to respiratory health, and also avoids dust pollution to the breeding environment, thus helping to achieve the goal of green and environmentally friendly production.

[0025] Please see Figures 1-5 This utility model discloses a high-efficiency and environmentally friendly dust-free pulverizing device, including a pulverizing box 1, a feeding port at the upper end of the pulverizing box 1, a discharging pipe 7 at the lower end of the pulverizing box 1, and a dust collection box 13 on one side of the pulverizing box 1.

[0026] The upper end of the crushing box 1 is provided with a first annular dust collection box 2, which is located above the feed inlet. The upper end of the first annular dust collection box 2 is provided with a detachable feeding pipe 3. The inner side of the first annular dust collection box 2 is provided with multiple first suction holes 4. The side of the first annular dust collection box 2 is provided with a first transfer pipe 6. The dust collection box 13 is provided with a placement groove 14, and a detachable filter frame 15 is provided in the placement groove 14. The top of the filter frame 15 is provided with a top plate 16, which is fixed to the upper end of the dust collection box 13. The outer side of the dust collection box 13 is provided with a negative pressure fan 17, and the suction end of the negative pressure fan 17 is connected to the filter frame 15. The first transfer pipe 6 is connected to the placement groove 14 through a first conduit 12.

[0027] The suction end of the negative pressure fan 17 is provided with a suction pipe that is inserted into the dust collection box 13 and communicates with the placement slot 14.

[0028] When using this high-efficiency, environmentally friendly, dust-free pulverizing device, the material is first fed into the first annular dust collection box 2 through the detachable feeding pipe 3, and then enters the pulverizing box 1 through the feed inlet for pulverization.

[0029] The top of the first annular dust collection box 2 is provided with a threaded groove 5, and the bottom end of the feeding pipe 3 is inserted into the threaded groove 5 and threadedly connected to the threaded groove 5.

[0030] The feeding pipe 3 is tightly screwed into the threaded groove 5 on the top of the first annular dust collection box 2. This threaded connection design facilitates quick disassembly and assembly of the feeding pipe 3 and creates a good sealing effect, effectively preventing dust from escaping when materials are fed in.

[0031] During the pulverization process, the negative pressure fan 17 located outside the dust collection box 13 is turned on. The negative pressure fan 17 is connected to the placement slot 14 inside the dust collection box 13 through a suction pipe, creating a negative pressure environment throughout the system.

[0032] Under this negative pressure, the first annular dust collection box 2 acts like a powerful "adsorption barrier," quickly drawing in the dust generated during material input and the flying debris raised during crushing through the first suction port 4. Subsequently, the dust and flying debris are precisely drawn into the placement slot 14 of the dust collection box 13 via a conveying channel composed of a transfer pipe and a conduit. The filter frame 15 in the placement slot 14 plays a crucial role, efficiently trapping the drawn-in dust and flying debris. The filtered gas is then discharged through the negative pressure fan 17, ensuring the cleanliness of the discharged gas. The bottom end of the discharge pipe 7 is equipped with an annular limiting plate 8 and a second annular dust collection box 9. The second annular dust collection box 9 is penetrated by the discharge pipe 7 and fixed to the lower end of the annular limiting plate 8. The lower end of the second annular dust collection box 9 is equipped with multiple second suction ports. A second transfer pipe 10 is located on one side of the annular limiting plate 8. The second transfer pipe 10 is connected to the placement slot 14 through a second conduit 11. The second annular dust collection box 9 is adhered to the lower end of the annular limiting plate 8.

[0033] After the material is crushed, the finished material is discharged through the conduit at the bottom of the crushing box 1. At the bottom of the conduit, the annular limiting plate 8 and the second annular dust collection box 9 form the "dust guard" of the discharge process.

[0034] Multiple second suction holes at the lower end of the second annular dust collection box 9 keenly capture the dust and debris generated during the discharge process. With the help of negative pressure, this dust and debris are also transported to the placement slot 14 of the dust collection box 13 through the transfer pipe and conduit, and are uniformly filtered by the filter frame 15.

[0035] The top plate 16 is fixed to the upper end of the dust collection box 13 by screws, and a sealing ring is provided between the top plate 16 and the dust collection box 13.

[0036] As usage time increases, when dust accumulates to a certain level inside the filter frame 15 and affects the filtration effect, simply unscrew the screws fixing the top plate 16 to easily remove the top plate 16, take out the filter frame 15 for cleaning or replacement. The operation is very convenient, ensuring that the equipment always maintains efficient dust collection and filtration performance.

[0037] The device's structural design fully considers actual operational needs. The threaded connection of the feeding pipe 3 allows operators to quickly replace the appropriate feeding pipe 3 according to different material characteristics and production requirements. At the same time, disassembling the feeding pipe 3 during equipment cleaning and maintenance is also easy.

[0038] The design of the filter frame 15 further embodies the concept of humanization. The top plate 16 is fixed with screws and a sealing ring ensures airtightness. After removing the top plate 16, the filter frame 15 can be easily removed, which makes it convenient for staff to regularly clean the dust and debris trapped in the filter frame 15, or replace the filter frame 15 in time when it is worn out, ensuring the continuous and stable operation of the dust collection system, reducing equipment maintenance time and costs, and improving overall production efficiency.

[0039] Both the first conduit 12 and the second conduit 11 are made of rubber hoses, and both the first annular dust collection box 2 and the second annular dust collection box 9 are made of metal.

[0040] The device balances performance and durability in its material selection. The conduit uses a rubber hose, whose excellent flexibility effectively cushions impacts during material transport, reducing wear and tear. The rubber hose is also easy to bend and arrange, allowing for flexible adaptation to different workspaces and equipment layouts. The first annular dust collection box 2 and the second annular dust collection box 9 are made of metal, giving the dust collection device strong structural strength and wear resistance. This allows it to operate stably under long-term negative pressure, resisting continuous dust erosion, preventing deformation and damage, extending equipment lifespan, reducing the frequency of maintenance and replacement due to material issues, and lowering the company's equipment operating costs.

[0041] Both the first annular dust collection box 2 and the second annular dust collection box 9 are made of metal, such as stainless steel 304, because they have excellent rust and corrosion resistance.

[0042] The feeding tube 3 is made of stainless steel and is adapted to connect with the threaded groove 5 on the top of the first annular dust collection box 2.

[0043] The dust collection box 13 is made of stainless steel and has sufficient strength to support the internal structure and the collected dust.

[0044] The filter frame 15 uses a stainless steel frame with high-efficiency filter materials, such as polyester fiber membrane filter media, with a filtration accuracy of 0.5-10 microns, which can effectively trap dust of different particle sizes.

[0045] The top plate 16 is made of stainless steel and is fastened to the upper end of the dust collection box 13 by screws. A sealing ring, such as a rubber sealing ring, is set at the connection to ensure airtightness.

[0046] The negative pressure fan model 17 can be a centrifugal negative pressure fan 17.

[0047] It will be understood by those skilled in the art that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
