Description

Technical Field

[0001] This invention relates to the field of dust removal technology, and in particular to an automatic ventilation and dust removal device for enclosed coal yard structures. Background Technology

[0002] In the enclosed environment of a coal yard, ventilation is often required. When coal dust is released from the ventilation system, a large amount of dust, slag, and other contaminants are generated, causing the ventilation system to discharge dust along with the coal dust. This can easily lead to environmental pollution. Therefore, effective treatment is needed at the ventilation end to remove dust particles and other pollutants carried in the exhaust ventilation to ensure environmental safety. Dust removal methods mainly include gravity settling dust removal, cyclone dust removal, and inertial dust removal. Among them, cyclone dust removal relies on centrifugal force to separate dust and has the characteristics of low cost and high temperature resistance. It is widely used in ventilation systems and industrial waste gas treatment.

[0003] The inventors discovered that during the ventilation and dust removal process in coal yards, it is impossible to quickly recover dust particles at the ventilation end, which easily leads to dust flying around and even escaping from the device, polluting the environment. Furthermore, after dust particle recovery, it is impossible to separate dust and slag during the slag discharge process, making direct and effective slag discharge difficult. Secondary processing of dust and slag is required, interrupting the dust removal operation, reducing dust removal efficiency, hindering continuous dust removal operation, and lowering the stability of the device. For example, existing patent CN214972795U discloses a wet cyclone dust collector. This wet cyclone dust collector improves flue gas dust removal efficiency by setting up a sedimentation tank and can utilize the wastewater generated during the dust removal process, offering the advantages of cleanliness and environmental protection. This solution can achieve the effect of dust sedimentation, but it still cannot effectively remove slag.

[0004] Therefore, how to provide an automatic ventilation and dust removal device for enclosed coal yard structures is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] One object of the present invention is to provide an automatic ventilation and dust removal device for a closed structure of a coal yard. The automatic ventilation and dust removal device for a closed structure of a coal yard according to the present invention includes a cyclone separator, an air inlet and an air outlet, a water recovery assembly, a dust removal assembly between the end of the cyclone separator and the recovery assembly, a lifting assembly connected to the dust removal assembly on the recovery assembly, a rotating assembly on the dust removal assembly, a primary filter assembly on the dust removal assembly, and a connection between the primary filter assembly and the water recovery assembly. The filter assembly is connected to a secondary filter assembly. A sliding component is provided on the recovery assembly, and a connecting component is provided between the sliding component and the primary filter assembly. A telescopic component is provided on the connecting component. During dust recovery, the lifting component moves downward, and the telescopic component and the connecting component move to a first state, immersing the outlet end of the dust discharge assembly in water, allowing the primary and secondary filter assemblies to collect dust. During slag discharge, the lifting component moves upward, and the telescopic component and the connecting component move to a second state, causing the dust discharge assembly to move upward, separating dust and slag between the primary and secondary filter assemblies.

[0006] Preferably, the recycling component includes a mounting frame disposed on the cyclone separator, a collection shell disposed on the mounting frame, a recycling bin disposed inside the collection shell, and a slag discharge space reserved between the collection shell and the recycling bin.

[0007] Preferably, the dust removal assembly includes a flexible hose disposed at the end of the cyclone separator, a mounting block is disposed on the flexible hose, a rotating tube is connected to the mounting block by a bearing, and a dust removal port is provided on the rotating tube.

[0008] Preferably, the lifting assembly includes a hydraulic lifting rod disposed within the collecting shell, and the output end of the hydraulic lifting rod is provided with a connecting plate, which is connected to the mounting block.

[0009] Preferably, the rotating assembly includes a rotating motor mounted on the mounting block, the output shaft of the rotating motor is connected to a drive gear, and the outer ring of the rotating tube is fixedly sleeved with a driven gear that meshes with the drive gear.

[0010] Preferably, the primary filtration assembly includes a mounting plate disposed on the rotating tube, the mounting plate being provided with a mounting sleeve, and an umbrella-shaped filter cloth being mounted on the mounting plate.

[0011] Preferably, the secondary filtration assembly includes a circular track disposed on the recycling bin, a rotating ring disposed on the circular track, and a second filter cloth connected to the end of the first filter cloth being mounted on the rotating ring.

[0012] Preferably, the sliding assembly includes a sliding ring slidably disposed within the recycling bin, a rotating ring being connected to the sliding ring by a bearing, and a locking rod being disposed on the sliding ring, with both the sliding ring and the locking rod penetrating through the recycling bin.

[0013] Preferably, the connecting assembly includes a first connecting rod hinged to the mounting sleeve, a second connecting rod hinged to the rotating ring, and a telescopic assembly disposed between the first connecting rod and the second connecting rod.

[0014] Preferably, the telescopic assembly includes a telescopic outer rod disposed on the first connecting rod, a telescopic inner rod disposed on the second connecting rod that passes through the telescopic outer rod, and a telescopic spring sleeved on the outer ring of the telescopic inner rod between the telescopic outer rod and the second connecting rod.

[0015] The beneficial effects of this invention are as follows:

[0016] This invention involves filling a recovery component with water to a suitable height. Exhaust air and dust are introduced into a cyclone separator through the air inlet. The cyclone separator separates the air, allowing it to exit through the outlet. A gas treatment system processes the exhaust air. Dust and other particulate matter accumulate at the end of the cyclone separator. After release, the dust is discharged through a dust removal component. During dust recovery, a lifting component is activated, lowering it and causing the dust removal component to descend. The dust removal component then lowers the primary filter component. When the primary filter component lowers the sliding component to its maximum limit, the sliding component stops descending, acting as a limit to prevent further descent. As the lifting component continues to descend, the connecting component moves, causing the telescopic component to first compress and then extend until the end of the dust removal component is submerged in water. The primary filter component then dips, while the secondary filter component seals the surrounding area, releasing the dust from the end of the cyclone separator. The dust is then released into the water through the dust removal component, achieving dust recovery. Because some dust floats and some settles after combining with water, making dust residue difficult to handle, the lifting component is activated in reverse during residue removal. The lifting component moves upward, causing the dust removal component to move upward. The dust removal component then moves the primary filter component upward. When the primary filter component moves the sliding component to its maximum extent, the sliding component stops moving upward again, creating a limiting effect to prevent it from moving further upward. As the lifting component continues to move upward, the connecting component moves, causing the telescopic component to first compress and then stretch until the end of the dust removal component is exposed. At this point, the primary filter component bulges upward, and the secondary filter component connects to the primary filter component. The rotating component is then activated, causing the dust removal component to rotate, forcing the primary and secondary filter components to rotate. Under centrifugal force, dust and slag are thrown out into the recovery component, achieving the slag removal effect. In summary, this application provides an automatic ventilation and dust removal device for a closed coal yard structure. It can achieve rapid recovery of dust particles, allowing the dust to fully contact with water and achieve a wetting effect on the dust particles, preventing dust from flying out of the device, which is beneficial to environmental protection. It can also achieve effective separation of water and dust and slag, achieving rapid slag removal without the need for secondary dust and slag treatment, ensuring continuous dust removal operation of the system, improving dust removal efficiency, and enhancing system stability.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0030] Example 1:

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5, Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic ventilation and dust removal device for a closed coal yard structure according to the present invention includes a cyclone separator 1, which is a prior art device capable of separating dust from ventilation. The cyclone separator 1 is provided with an air inlet 2 connected to a ventilation system and an air outlet 3 connected to a gas treatment system to treat the ventilation and discharge it after it meets standards. A water-filled recovery component 4 is provided on the cyclone separator 1 to collect dust and discharge the dust residue. A dust removal component 5 is provided between the end of the cyclone separator 1 and the recovery component 4 to release dust from the bottom of the cyclone separator 1. A lifting component 6 connected to the dust removal component 5 is provided on the recovery component 4 to achieve a lifting effect. A rotating component 7 is provided on the dust removal component 5 to provide rotational force. A primary filter component 8 is provided on the dust removal component 5. The filter assembly 8 collects most of the dust. The recovery assembly 4 is equipped with a secondary filter assembly 9 connected to the primary filter assembly 8. The secondary filter assembly 9 serves as a seal and provides auxiliary filtration. The recovery assembly 4 is equipped with a sliding assembly 10, which slides up and down. A connecting assembly 11 is provided between the sliding assembly 10 and the primary filter assembly 8. A telescopic assembly 12 is provided on the connecting assembly 11. The connecting assembly 11 and the telescopic assembly 12 work together to avoid movement interference. When collecting dust, the lifting assembly 6 moves down, and the telescopic assembly 12 and the connecting assembly 11 move to the first state, so that the outlet end of the dust discharge assembly 5 is immersed in water, and the primary filter assembly 8 and the secondary filter assembly 9 collect dust. When discharging slag, the lifting assembly 6 moves up, and the telescopic assembly 12 and the connecting assembly 11 move to the second state, so that the dust discharge assembly 5 moves up, and the primary filter assembly 8 and the secondary filter assembly 9 separate dust and slag.

[0032] Working principle: Water is filled into the recovery component 4 to a suitable height. Exhaust air and dust are introduced into the cyclone separator 1 through the air inlet 2. The separation function of the cyclone separator 1 allows the air to be discharged through the air outlet 3. The exhaust air is treated by the gas treatment system. At this time, dust and other particles accumulate at the end of the cyclone separator 1. After release, the dust is discharged through the dust removal component 5. When recovering dust, the lifting component 6 is activated. The lifting component 6 descends, which drives the dust removal component 5 to descend. The dust removal component 5 drives the primary filter component 8 to descend. The primary filter component 8 drives the sliding component 10 to descend to its maximum extent. The moving component 10 stops descending, acting as a limit to prevent the sliding component 10 from continuing to descend. As the lifting component 6 continues to descend, the connecting component 11 moves, causing the telescopic component 12 to first compress and then extend until the end of the dust removal component 5 is immersed in water. The primary filter component 8 then dips down, while the secondary filter component 9 forms a seal around the perimeter, releasing the dust from the end of the cyclone separator 1. The dust is then released into the water through the dust removal component 5, thus achieving dust recycling. Because some dust floats and some settles after combining with water, making dust residue difficult to handle, the lifting component is activated in reverse during residue removal. 6. The lifting component 6 moves upward, causing the dust removal component 5 to move upward. The dust removal component 5 then moves the primary filter component 8 upward. When the primary filter component 8 moves the sliding component 10 to its maximum limit, the sliding component 10 stops moving upward again, forming a limit to prevent it from moving further upward. When the lifting component 6 continues to move upward, the connecting component 11 moves, causing the telescopic component 12 to first compress and then stretch until the end of the dust removal component 5 is exposed. At this time, the primary filter component 8 bulges upward, and the secondary filter component 9 connects to the primary filter component 8. The rotating component 7 is then activated, and its rotation causes the dust removal component 5 to rotate, forcing it to... The primary filter assembly 8 and the secondary filter assembly 9 rotate, and under the action of centrifugal force, dust and sludge are thrown into the recovery assembly 4, achieving the effect of sludge discharge. In summary, the automatic ventilation and dust removal device for the closed structure of the coal yard of this application can achieve rapid recovery of dust particles, allowing the dust to come into full contact with water, achieving the effect of wetting the dust particles, preventing dust from flying out of the device, which is beneficial to environmental protection. It can also achieve effective separation of water and dust and sludge, achieving rapid sludge discharge without the need for secondary dust and sludge treatment, ensuring continuous dust removal operation of the system, improving dust removal efficiency, and improving system stability.

The mounting frame 401 provides support, and a collection shell 402 is mounted on the mounting frame 401 to block dust and slag, facilitating the collection of dust and slag. A recovery box 403 is provided inside the collection shell 402, and the recovery box 403 is filled with water. The recovery box 403 is provided with a water inlet and a water outlet for replacing the water. A slag discharge space is reserved between the collection shell 402 and the recovery box 403.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic ventilation and dust removal device for a closed structure in a coal yard according to the present invention includes a dust removal component 5 comprising a flexible hose 501 disposed at the end of a cyclone separator 1. The flexible hose 501 is extendable when moving up and down. An installation block 502 is disposed on the flexible hose 501. A rotating tube 503 is connected to the installation block 502 by a bearing. The rotating tube 503 is arranged vertically and has a dust discharge port 504 for discharging dust. The flexible hose 501, the installation block 502, and the rotating tube 503 are all connected.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic ventilation and dust removal device for a closed structure of a coal yard according to the present invention includes a lifting assembly 6 comprising a hydraulic lifting rod 601 disposed in a collection shell 402. The hydraulic lifting rod 601 is vertically disposed to provide up and down movement. A connecting plate 602 is disposed at the output end of the hydraulic lifting rod 601, and the connecting plate 602 is connected to the mounting block 502.

[0037] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, an automatic ventilation and dust removal device for a closed structure of a coal yard according to the present invention includes a rotating component 7 comprising a rotating motor 701 mounted on a mounting block 502, the output shaft of the rotating motor 701 being connected to a drive gear 702, and a driven gear 703 meshing with the drive gear 702 being fixedly sleeved on the outer ring of the rotating tube 503. The size of the drive gear 702 and the driven gear 703 can be adjusted appropriately according to actual use.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic ventilation and dust removal device for a closed structure in a coal yard according to the present invention includes a primary filter assembly 8 comprising an installation plate 801 disposed on a rotating tube 503, an installation sleeve 802 disposed on the installation plate 801, the installation plate 801 and the installation sleeve 802 forming an integral unit, and an umbrella-shaped filter cloth 803 installed on the installation plate 801, the filter cloth 803 having a filtering effect, blocking dust while allowing water to pass through.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic ventilation and dust removal device for a closed structure in a coal yard according to the present invention includes a secondary filtration component 9 comprising a circular track 901 disposed on a recycling bin 403, a rotating ring 902 disposed on the circular track 901, and a second filter cloth 903 mounted on the rotating ring 902 and connected to the end of a first filter cloth 803. The second filter cloth 903 has a filtration effect, blocking dust while allowing water to pass through, and at the same time, the second filter cloth 903 provides auxiliary filtration for the first filter cloth 803.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, an automatic ventilation and dust removal device for a closed structure in a coal yard according to the present invention includes a sliding component 10 comprising a sliding ring 1001 slidably disposed within a recycling bin 403. A sliding groove is provided on the inner wall of the recycling bin 403, and the sliding ring 1001 moves within the sliding groove. The sliding direction of the sliding ring 1001 is up and down. A rotating ring 1002 is connected to the sliding ring 1001 by a bearing, and the rotating ring 1002 can rotate. A locking rod 1003 is provided on the sliding ring 1001, and the locking rod 1003 provides stability. Both the sliding ring 1001 and the locking rod 1003 penetrate the recycling bin 403.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic ventilation and dust removal device for a closed structure in a coal yard according to the present invention includes a connecting assembly 11 comprising a connecting rod 1101 hinged to a mounting sleeve 802, a connecting rod 2 1102 hinged to a rotating ring 1002, a telescopic assembly 12 disposed between the connecting rod 1101 and the connecting rod 2 1102, and a filter cloth 803 connected to the connecting rod 1101 and the connecting rod 2 1102. The filter cloth 803 is telescopically extended when the connecting rod 1101 and the connecting rod 2 1102 move.

[0042] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic ventilation and dust removal device for a closed structure in a coal yard according to the present invention includes a telescopic component 12 comprising a telescopic outer rod 1201 disposed on a connecting rod 1101, a telescopic inner rod 1202 disposed on a connecting rod 2102 and passing through the telescopic outer rod 1201, and a telescopic spring 1203 sleeved on the outer ring of the telescopic inner rod 1202 between the telescopic outer rod 1201 and the connecting rod 2102, wherein the telescopic outer rod 1201 and the telescopic inner rod 1202 are both arranged along the length direction of the connecting rod 1101 or the connecting rod 2102.

[0043] Working principle: Water is filled into the recycling tank 403 to a reasonable height. Exhaust air and dust are introduced into the cyclone separator 1 through the air inlet 2. Through the working principle and separation function of the cyclone separator 1, the air is forced to be discharged through the air outlet 3. The exhaust air is treated by the gas treatment system to meet the emission standards. Dust and other particulate matter are collected at the bucket-shaped end of the cyclone separator 1 and discharged through the dust outlet 504 after release.

[0044] When collecting dust, the hydraulic lifting rod 601 is activated. The output end of the hydraulic lifting rod 601 drives the connecting plate 602 to descend. The connecting plate 602 drives the mounting block 502 to descend. The mounting block 502 drives the rotating tube 503 to descend. The rotating tube 503 drives the mounting plate 801 and the mounting sleeve 802 to descend, causing the filter cloth 803 to descend synchronously. The mounting sleeve 802 drives the connecting rod 1101, the connecting rod 2 1102, and the telescopic assembly 12 to descend. When the connecting rod 2 1102 drives the sliding ring 1001 and the rotating ring 1002 to descend to their maximum extent, the collection shell 402 restricts the movement of the sliding ring 1001 and the locking rod 1003 to prevent the sliding ring 1001 from descending further. When the hydraulic lifting rod 601 continues to descend, the connecting rod 2 1102, the connecting rod 1 1101, and the telescopic assembly 12 rotate around the hinge point. The telescopic inner rod 1202 slides within the telescopic outer rod 1201. The telescopic spring 1203 is first compressed and then stretched, causing the connecting rod 1101 and the connecting rod 2102 to cause the filter cloth 803 to first contract and then open. The filter cloth 803 also causes the filter cloth 903 to move. Since the hinge point of the connecting rod 2102 is close to the filter cloth 903, the movement of the filter cloth 903 is small until the rotating tube 503 and the dust discharge port 504 are immersed in the water of the recovery box 403, causing the filter cloth 803 to form a concave state. At the same time, the filter cloth 903 fills the gap between the filter cloth 803 and the inner wall of the recovery box 403, forming a sealing effect. The dust at the end of the cyclone separator 1 is released through the hose 501, the mounting block 502, the rotating tube 503 and the dust discharge port 504, releasing the dust particles into the water, thereby achieving the dust recovery effect.

[0045] Because some dust floats and some settles after combining with water, making it difficult to handle the dust residue, the hydraulic lifting rod 601 is activated in reverse during slag discharge. The output end of the hydraulic lifting rod 601 drives the connecting plate 602 to move upward, which in turn drives the mounting block 502 to move upward. The mounting block 502 drives the rotating tube 503 to move upward, which in turn drives the mounting plate 801 and mounting sleeve 802 to move upward. This causes the filter cloth 803 to move upward synchronously. The mounting sleeve 802 drives the connecting rod 1101, the connecting rod 2 1102, and the telescopic assembly 12 to move upward. When the connecting rod 2 1102 drives the sliding ring 1001 and the rotating ring 1002 to move upward to their maximum extent, the collection shell 402 restricts the movement of the sliding ring 1001 and the locking rod 1003, preventing the sliding ring 1001 from continuing to move upward. As the hydraulic lifting rod 601 continues to move upward, connecting rod 2 1102, connecting rod 1 1101, and telescopic assembly 12 rotate around the hinge point. The telescopic inner rod 1202 slides inside the telescopic outer rod 1201, and the telescopic spring 1203 is still compressed and then stretched. This causes connecting rod 1 1101 and connecting rod 2 1102 to drive filter cloth 1 803 to contract and then open. Filter cloth 1 803 drives filter cloth 2 903 to move until the rotating tube 503 and dust discharge port 504 are exposed from underwater in the recovery box 403, until filter cloth 1 803 forms an upward convex state. At the same time, filter cloth 2 903 connects to filter cloth 1 803, achieving a sealing effect while facilitating the rolling of dust and sludge. This forces filter cloth 2 903 and filter cloth 1 803 to move synchronously with the floating dust and settled dust.

[0046] When discharging dust and sludge, the rotating motor 701 is started. The output shaft of the rotating motor 701 rotates, driving the drive gear 702 to rotate. The drive gear 702 rotates, driving the driven gear 703 to rotate. The driven gear 703 rotates, driving the rotating tube 503 to rotate. The rotating tube 503 rotates, driving the mounting plate 801 and mounting sleeve 802 to rotate. The mounting plate 801 drives the first filter cloth 803 to rotate. Under the action of the circular track 901 and the rotating ring 902, the first filter cloth 803 drives the second filter cloth 903 to rotate. At the same time, the mounting sleeve 802 drives the first connecting rod 1101 to rotate. The rotation of the first connecting rod 1101... The rotation of the telescopic outer rod 1201, the telescopic inner rod 1202, and the telescopic spring 1203 forces the connecting rod 1102 to rotate. Under the action of the sliding ring 1001 and the locking rod 1003, the connecting rod 1102 drives the rotating ring 1002 to rotate. Due to the rotation of the filter cloth 803 and the filter cloth 903, under the action of centrifugal force, the dust and sludge on the filter cloth 803 and the filter cloth 903 are thrown out, causing the dust and sludge to fall into the sludge discharge space between the collection shell 402 and the recycling box 403. The dust and sludge are collected by the collection equipment, achieving the sludge discharge effect while effectively preventing dust from flying.

[0047] This solution enables rapid recovery of dust particles, allowing for full contact between the dust and water to wet the particles and prevent them from escaping the device, thus protecting the environment. Furthermore, it effectively separates water from dust and slag, enabling rapid slag discharge without the need for secondary dust and slag treatment, ensuring continuous dust removal operation, improving dust removal efficiency, and enhancing system stability. The device employs a closed structure, making it particularly suitable for enclosed environments such as coal yards.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
