Abstract
Description
Technical Field
[0001] This utility model relates to the field of ferrovanadium production technology, specifically to a dust collection device for a ferrovanadium crusher. Background Technology
[0002] During the crushing and processing of ferrovanadium, a large amount of dust is generated. This dust not only pollutes the environment but also poses a threat to the health of operators. Traditional ferrovanadium crushers often lack effective dust collection devices, causing dust to fly everywhere during processing and be difficult to control.
[0003] Furthermore, some existing dust collection devices suffer from poor sealing, failing to ensure complete dust collection during the crushing process, resulting in some dust leaking into the environment. Additionally, the filtration efficiency of these devices is often unsatisfactory, failing to effectively separate dust from the air, leading to the collection of dust containing a large amount of impurities and making subsequent processing difficult.
[0004] Furthermore, traditional dust collection devices have shortcomings in terms of unloading and dust aggregation. Dust is easily generated during unloading, and poor dust aggregation will affect the collection efficiency of the device. At the same time, the design of the filter structure is often not reasonable enough, and the replacement and maintenance of filter elements are cumbersome, increasing the cost of use. There may be technical solutions to the above problems in the existing technology, but this case aims to provide an alternative or replacement technical solution. Utility Model Content
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a dust collection device for a vanadium-iron crusher, comprising: a crushing box, a sealed crushing structure, and a dust collection structure, wherein the sealed crushing structure is installed on the crushing box, and the dust collection structure is connected to the sealed crushing structure, and the sealed crushing structure includes: a sealed feeding bucket, a rotary sealed shaft tube, a sealed drive motor, a sealed gearbox, a sealed diversion pipe, an air pump, an air inlet tube, a pair of sealed U-shaped airbags, and a pair of arc-shaped sealing blocks;
[0006] The sealed feeding hopper is inserted into the crushing box. The sealed feeding hopper has a feeding port and a discharging port. The rotary sealing shaft tube is inserted into the sealed feeding hopper through a bearing. A pair of arc-shaped sealing blocks are installed on the rotary sealing shaft tube. A pair of sealing loop-shaped airbags are respectively inserted into the pair of arc-shaped sealing blocks. The sealing gearbox is fitted onto the rotary sealing shaft tube. The driving end of the sealing drive motor is connected to the sealing gearbox. A pair of sealing loop-shaped airbags are respectively installed on the pair of arc-shaped sealing blocks. The sealing diversion pipe is inserted into the rotary sealing shaft tube and the pair of sealing loop-shaped airbags. The air pump is installed on the crushing box. The air pump inner tube is connected to the air pump, and the air pump inner tube is inserted into the sealing diversion pipe through a bearing.
[0007] It should be noted that, in the above process, the gas inside the pair of sealed loop-shaped airbags is first discharged. The raw material is then guided to the inside of the sealed feeding hopper. The sealing drive motor is then activated, causing the rotating sealing shaft tube on the drive end of the sealing drive motor to rotate stably. The rotating sealing shaft tube drives the pair of arc-shaped sealing blocks on it, thereby guiding the raw material inside the pair of arc-shaped sealing blocks to the inside of the crushing chamber. The air pump is then activated to inflate the air inlet pipe and the sealing distribution pipe. The gas is then guided to the inside of the pair of sealed loop-shaped airbags through the sealing distribution pipe. The expansion of the pair of sealed loop-shaped airbags expands and seals the pair of arc-shaped sealing blocks with the sealed feeding hopper.
[0008] Preferably, the dust collection structure includes: an air extraction pipe, a filter box, several refractive plates, an exhaust pump, several replaceable filter inner boxes, filter carbon, filter screen, and filter cotton.
[0009] The filter box is installed on the crushing box, the air extraction pipe is connected to the filter box and the sealed feeding barrel, the exhaust pump is installed on the filter box, a number of the refractive plates are respectively cross-installed on the inner side of the filter box, a number of the replaceable filter inner boxes are evenly installed on the inner side of the filter box, and the filter carbon, the filter screen and the filter cotton are respectively installed on the inner side of the number of replaceable filter inner boxes.
[0010] It should be noted that, as described above, the air inside the filter box is discharged by the exhaust pump, creating a negative pressure inside the filter box. This negative pressure is used to draw the air inside the sealed feeding hopper through the air extraction pipe. The air then passes through several refractive plates, several replaceable filter boxes, filter carbon, filter screen, and filter cotton inside the filter box, thereby drawing away the dust generated during crushing.
[0011] Preferably, the inner side of the crushing box is provided with an electromagnetically sealed unloading door.
[0012] Preferably, a funnel-shaped agglomerating block is provided on the inner side of the crushing box.
[0013] Preferably, a spiral-shaped limiting block is provided on the inner side of each of the plurality of the refractive plates.
[0014] Preferably, each of the plurality of the loop-shaped limiting blocks is provided with a limiting rubber ring. Beneficial effects
[0015] This utility model provides a dust collection device for a vanadium-iron crusher. It offers the following advantages compared to existing technologies: Its sealed crushing structure is ingeniously designed. Through the cooperation of the sealed feeding hopper and the rotating sealed shaft tube, as well as the expansion seal of the sealed loop-shaped airbag, the sealing of the raw material during the crushing process is ensured, effectively preventing dust leakage. Simultaneously, the transmission of the sealed drive motor and sealed gearbox is stable and reliable, ensuring smooth crushing. The dust collection structure is equally excellent. A negative pressure is generated by the exhaust pump, and the air in the sealed feeding hopper is guided to the filter box through the suction pipe. After multiple layers of filtration—including a refractive plate, filter carbon, filter screen, and filter cotton in the replaceable filter inner box—the dust generated during crushing is effectively collected and treated, maintaining a clean working environment. Furthermore, the electromagnetically sealed discharge door and the horn-shaped collecting block design inside the crushing box facilitate the unloading of raw materials and the collection of dust. The loop-shaped limiting block and limiting rubber ring on the inner side of the refractive plate enhance the stability and durability of the structure, making the entire device more reliable and practical.

On box 1, the inflation inner tube 8 is connected to the inflation pump 7, and the inflation inner tube 8 is inserted into the sealed diversion pipe 6 via a bearing; the dust collection structure includes: an air extraction pipe 11, a filter box 12, several refractive plates 13, an exhaust pump 14, several replaceable filter inner boxes 15, filter carbon, filter screen, and filter cotton; the filter box 12 is mounted on the crushing box 1, the air extraction pipe 11 is connected to the filter box 12 and the sealed feeding hopper 2, and the exhaust pump 14 is mounted on the filter box 12.
