Description

Technical Field

[0001] This invention relates to the field of dust purification technology, and in particular to a mobile integrated dust collection and purification machine for mines. Background Technology

[0002] During the production operations of mining and ore processing, a large amount of dust is generated in processes such as feeding, crushing, screening, and transfer. This dust not only flies in large quantities in the work area, causing air pollution in the work environment, but also has an adverse effect on the health of on-site workers. At the same time, the accumulation of dust affects the normal operation of mining production equipment.

[0003] Currently, most dust collection and purification devices in mines filter and intercept dust-laden air using filters, and combine this with water adsorption to purify the dust. During the filtration process, a large amount of dust adheres to the surface of the filters. Currently, most devices rely on the dust's own weight to naturally fall off and clean the filters. However, due to the wind pressure generated by the device's exhaust, the dust is difficult to fall off the filter surface, easily causing filter blockage, leading to a rapid decrease in filtration efficiency and affecting operations. Furthermore, most filters are fixed installation structures. When the filters are blocked or damaged, multiple parts of the device need to be disassembled to complete the replacement and cleaning, which is cumbersome and has poor maintenance efficiency. Summary of the Invention

[0004] This invention is based on the inventor's discoveries and understanding of the following facts and problems:

[0005] Dust adhering to the filter is difficult to remove and easily causes blockage.

The processing mechanism includes a first housing, a water tank, a collection box, and an exhaust fan. The first housing and the water tank are connected to the mobile body, and the first housing has a ventilated area. The exhaust fan is arranged inside the first housing, and the air inlet of the exhaust fan is connected to the water tank. At least a portion of the collection box is located inside the first housing and is slidably connected to the first housing. The filtering mechanism includes a second housing, a drive motor, a scraper, and a filter screen. The second housing is covered with... The first housing is positioned above the second housing. The drive motor is arranged beside the second housing and penetrates into the second housing. The scraper is connected to the drive motor via a rotating shaft.

[0010] In some embodiments, an access port is provided on each of the two opposite side walls of the second housing, and a sealing plate is provided at the access port. The sealing plate is used to allow the filter screen to pass through after it is removed.

[0011] In some embodiments, a perforated plate is embedded in the ventilated area of ​​the first box. The perforated plate is located on the exhaust side of the exhaust fan and is used to exhaust purified air and assist in heat dissipation. There are two sets of perforated plates, which are respectively fixed to the front and rear of the inner wall of the first box by bolts. A guide space is formed between the two sets of perforated plates for sliding and limiting the material collection box.

[0012] In some embodiments, a grid frame is also fixed inside the second housing, the rotating shaft of the scraper is rotatably supported at the center of the grid frame, and the grid frame is located on the air intake side of the filter screen to form physical protection.

[0013] In some embodiments, the grid frame is fixedly connected to the inner wall of the second housing by bolts, and the sealing plate is detachably connected to the side wall of the second housing by bolts. The sealing plate covers the outside of the inspection port and forms a sealed protection.

[0014] In some embodiments, the first housing and the movable body are connected by bolts, the exhaust fan is fixedly arranged on the lower inner wall of the first housing by bolts, the air inlet of the exhaust fan is connected to the water tank through an exhaust pipe, and the exhaust pipe is used to directionally transport the purified air in the water tank to the exhaust fan.

[0015] In some embodiments, the riser passes through the lower inner wall of the second housing and the inner wall of the first housing in sequence and extends to the lower liquid level of the water tank.

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] This invention provides a mobile integrated dust collection and purification machine for mines, comprising a mobile body 1 and a processing mechanism 2, a filtering mechanism 3, and a conveying mechanism 4 arranged on the mobile body 1. The processing mechanism 2 includes a first housing 201, a water tank 206, a collection box 203, and an exhaust fan 204. The first housing 201 and the water tank 206 are connected to the mobile body 1, and the first housing 201 has a ventilated area. The exhaust fan 204 is arranged inside the first housing 201, and the air inlet of the exhaust fan 204 is connected to the water tank 206. At least a portion of the collection box 203 is located inside the first housing 201 and is slidably connected to the first housing 201. The filtering mechanism 3 includes a second housing 301, a drive motor 303, a scraper 307, and a filter screen 306. The second housing 301... The first housing 201 is positioned above the second housing 301. The drive motor 303 is positioned beside the second housing 301 and extends into the second housing 301. The scraper 307 is connected to the drive motor 303 via a rotating shaft 304. The scraper 307 abuts against the filter screen 306, which is movably positioned inside the second housing 301. The air outlet of the second housing 301 extends through a riser 309 to the bottom of the water tank 206. The conveying mechanism 4 includes a housing 401, an auger, and a second motor 402. The housing 401 is located between the first housing 201 and the second housing 301. The second motor 402 is positioned beside the housing 401. The auger is located inside the housing 401 and is connected to the second motor 402. The housing 401 is connected to the collection box 203 to convey dust.

[0028] The mobile unit 1 provides an installation base for various mechanisms, eliminating the limitations of fixed operations and allowing for flexible relocation to improve the timeliness of dust handling. The mobile unit 1 can be a trolley, etc. The first housing 201 provides installation space for the exhaust fan 204 and the collection box 203. The ventilation area ensures air circulation inside the device and meets the heat dissipation requirements of the exhaust fan 204 during operation. The water tank 206 stores water to adsorb and purify dust-laden air. The exhaust fan 204 provides the exhaust power. The connection between the air inlet and the water tank 206 forms a negative pressure air passage, realizing the intake of dust-laden air from the outside and the exhaust of purified air. The sliding connection between the collection box 203 and the first housing 201 allows the collection box 203 to be quickly pulled out for dust dumping and cleaning without disassembling the whole unit, improving the convenience of later maintenance.

[0029] The filter mechanism 3 is arranged vertically above the first housing 201, saving horizontal space and making the overall structure more compact. The drive motor 303 passes through the second housing 301 and drives the scraper 307 to rotate via the rotating shaft 304. The scraper 307 abuts against the filter screen 306, scraping off the dust adhering to the surface of the filter screen 306, preventing the filter screen 306 from clogging and ensuring continuous filtration efficiency. The filter screen 306 is movably arranged inside the second housing 301 for easy disassembly, replacement, and cleaning. The air outlet of the second housing 301 extends through the riser 309 to below the liquid surface of the water tank 206, allowing the dust-laden air after the initial filtration by the filter screen 306 to directly enter the water. The water adsorbs and removes fine dust from the air, achieving secondary purification. The outer casing 401 of the conveying mechanism 4 is located between the first housing 201 and the second housing 301, forming a closed dust conveying channel through the gap between the two housings to prevent secondary dust re-entrainment. The second motor 402 drives the auger to rotate inside the outer casing 401, using the auger's spiral to convey and scrape the dust into the collection box 203. The connection between the outer casing 401 and the collection box 203 enables directional dust collection, allowing the dust to be centrally stored in the collection box 203. Thus, the device achieves a workflow of dust intake - primary filtration - secondary purification - dust conveying and collection - clean air discharge. This solves the problems of easy filter clogging and poor purification effect in traditional mine dust collection devices, and through structural integration and mobile design, improves the device's operational convenience, operational flexibility, and dust handling efficiency. In some embodiments, U-shaped guide plates 305 are symmetrically arranged on the inner wall of the second housing 301, with the opening directions of the U-shaped guide plates 305 facing each other, and the two ends of the filter screen 306 are respectively slidably embedded in a U-shaped guide plate 305.

[0030] Specifically, the U-shaped guide plate 305 provides sliding guidance and installation limit for the filter screen 306. The U-shaped structure can conform to the end contour of the filter screen 306, allowing the filter screen 306 to be smoothly pulled along the extension direction of the guide plate, avoiding horizontal deviation and shaking of the filter screen 306, ensuring that the filter screen 306 is in the preset filtration position, and keeping the contact position between the scraper 307 and the filter screen 306 precise. The symmetrically arranged U-shaped guide plates 305 ensure that the filter screen 306 is evenly stressed, preventing deformation or jamming due to unilateral stress, reducing the difficulty of filter screen maintenance. The enclosure of the U-shaped guide plate 305 protects the end of the filter screen 306, reducing direct friction between the filter screen 306 and the inner wall of the second housing 301, and extending the service life of the filter screen 306.

[0031] In some embodiments, an access port is provided on each of the two opposite side walls of the second housing 301, and a sealing plate 308 is provided at the access port. The sealing plate 308 is used to pass through the filter screen 306 after being removed.

[0032] Specifically, after the sealing plate 308 is disassembled, the filter screen 306 can pass through. The two opposing access ports form a two-way channel for the filter screen 306 to be pulled out and installed, allowing the filter screen 306 to be easily pulled out or installed from either access port. This reduces the difficulty of disassembling, replacing, and cleaning the filter screen 306, eliminating the need to completely disassemble the second housing 301 and improving the efficiency of filter maintenance. The sealing plate 308 at the access port forms a closed protection for the access port when the device is working normally, preventing air leakage, maintaining a stable airflow, and ensuring the efficiency of the initial filtration. At the same time, the sealing plate 308 can also prevent external debris from entering the interior of the second housing 301 through the access port, preventing debris from adhering to the filter screen 306 or scraper 307 and affecting the device.

[0033] Optionally, a sealing gasket is provided at the contact point between the sealing plate 308 and the second housing 301 to improve the sealing effect and prevent leakage of dusty air. The size of the access port is adapted to the outer dimensions of the filter screen 306 to ensure that the filter screen 306 can be easily installed, reducing the opening area of ​​the access port, reducing the coverage area of ​​the sealing plate 308, improving the sealing stability of the sealing plate 308, and providing protective chamfers at the edges of the access port to prevent the filter screen from being scratched by sharp edges when disassembling and assembling the filter screen 306, thus improving safety.

[0034] In some embodiments, a perforated plate 202 is embedded in the ventilated area of ​​the first housing 201. The perforated plate 202 is located on the exhaust side of the exhaust fan 204 and is used to exhaust the purified air and assist in heat dissipation. There are two sets of perforated plates 202. The two sets of perforated plates 202 are respectively fixed to the front and rear parts of the inner wall of the first housing 201 by bolts. A guide space is formed between the two sets of perforated plates 202 for sliding and limiting the material collection box 203.

[0035] Specifically, the perforated plate 202 embedded in the ventilated area, located on the exhaust side of the exhaust fan 204, can receive the purified air discharged by the exhaust fan 204. The perforation facilitates exhaust while preventing external debris from entering the first housing 201 through the ventilated area and causing damage. The heat generated during the operation of the exhaust fan 204 is dissipated with the air, and the perforated plate 202 accelerates airflow inside the first housing 201, thus aiding in heat dissipation. The two sets of perforated plates 202 are fixed to the front and rear of the inner wall of the first housing 201 with bolts, ensuring a secure connection between the perforated plates 202 and the first housing 201 while facilitating disassembly for cleaning or replacement. The guide space formed between the two sets of hollow plates 202 forms a sliding limit for the collection box 203, allowing the collection box 203 to be pulled and moved along the extension direction of the guide space, avoiding the collection box 203 from deviating or getting stuck during the pulling process, preventing the collection box 203 from shifting position and ensuring that the dust can fall accurately into the collection box 203.

[0036] In some embodiments, a grid frame 302 is also fixed inside the second housing 301, the rotating shaft 304 of the scraper 307 is rotatably supported at the center of the grid frame 302, and the grid frame 302 is located on the air intake side of the filter screen 306 to form physical protection.

[0037] Specifically, the grid frame 302 rotatably supports the rotating shaft 304 of the scraper 307 at its center, providing a stable support point for the rotating shaft 304, limiting radial offset during rotation, and ensuring precise movement of the scraper 307 as it rotates, guaranteeing that the scraper 307 remains in contact with the filter screen 306. The central support of the grid frame 302 reduces stress and wear at the connection point between the rotating shaft 304 and the second housing 301, extending service life. Located on the air inlet side of the filter screen 306, the grid frame 302 does not obstruct dusty airflow through the filter screen 306. The grid also protects the filter screen 306, preventing large debris from impacting and damaging it, and preventing the scraper 307 from wobbling and colliding with the inner wall of the second housing 301.

[0038] In some embodiments, the grid frame 302 is fixedly connected to the inner wall of the second housing 301 by bolts, and the sealing plate 308 is detachably connected to the side wall of the second housing 301 by bolts. The sealing plate 308 covers the outside of the inspection port and forms a sealed protection.

[0039] Specifically, the grid frame 302 is bolted to the inner wall of the second housing 301, ensuring a secure connection between the grid frame 302 and the second housing 301, providing rotational support for the rotating shaft 304 and resisting vibration. The grid frame 302 can be easily removed by unscrewing the bolts for convenient inspection, cleaning, and maintenance. The sealing plate 308 is detachably bolted to the side wall of the second housing 301, allowing the sealing plate 308 to fit tightly against the outside of the inspection port, preventing dust-laden air leakage and maintaining negative pressure inside the second housing 301.

[0040] In some embodiments, the first housing 201 is connected to the movable body 1 by bolts, and the exhaust fan 204 is fixedly arranged below the inner wall of the first housing 201 by bolts. The air inlet of the exhaust fan 204 is connected to the water tank 206 through the exhaust pipe 205. The exhaust pipe 205 is used to directionally transport the purified air in the water tank 206 to the exhaust fan 204.

[0041] Specifically, the first housing 201 and the mobile body 1 are connected by bolts to ensure that the first housing 201 is firmly installed on the mobile body 1, resisting the vibration and impact during the movement and operation of the device, and preventing the first housing 201 from shifting or loosening. The first housing 201 and the mobile body 1 can be easily separated by removing the bolts, which is convenient for individual inspection, maintenance and replacement, and is suitable for the maintenance needs of complex mining operations. The exhaust fan 204 is fixed to the lower inner wall of the first housing 201 by bolts to prevent the exhaust fan 204 from shifting due to vibration during operation, and to ensure the stable exhaust power of the exhaust fan 204.

[0042] The air inlet of the exhaust fan 204 is connected to the water tank 206 via an exhaust pipe 205. The exhaust pipe 205 provides directional delivery of the clean air that has undergone secondary purification in the water tank 206, allowing the air to enter the exhaust fan 204 stably along a preset path. This avoids turbulence between the water tank 206 and the exhaust fan 204, ensuring smooth airflow and improving exhaust efficiency. A sealed structure is formed between the water tank 206 and the exhaust fan 204 to prevent clean air leakage and ensure that the negative pressure generated by the exhaust fan 204 is effective in drawing in dusty air.

[0043] In some embodiments, the riser 309 passes through the lower inner wall of the second housing 301 and the inner wall of the first housing 201 in sequence and extends to the lower liquid surface of the water tank 206. The penetration points of the riser 309 with the second housing 301 and the first housing 201 are sealed to seal and transport the dust-laden air in the second housing 301 to the water tank 206.

[0044] Specifically, the riser 309 penetrates the lower inner wall of the second chamber 301 and the inner wall of the first chamber 201, extending to below the liquid surface of the water tank 206. The riser 309 forms an air passage from the second chamber 301 to the water tank 206, directly transporting the dust-laden air that has undergone initial filtration in the second chamber 301 to the water in the water tank 206. This ensures sufficient contact between the dust-laden air and the water, achieving secondary purification through adsorption and preventing secondary diffusion caused by contact with outside air during transport. Simultaneously, the penetration position at the lower inner wall is adapted to the airflow direction of the second chamber 301, allowing the dust-laden air inside the chamber to smoothly enter the riser 309 without any stagnation or dead zones. The riser 309 extending below the liquid surface allows the dust-laden air to form bubble-like circulation in the water, increasing the contact area and contact time between air and water, thus improving the adsorption effect of fine dust. The integrated riser 309 connects the air path between the filter mechanism 3 and the treatment mechanism 2, ensuring a smooth multi-stage purification process. Combined with the seal, it enables directional, sealed, and efficient delivery of dust-laden air, guaranteeing the connection from primary filtration to secondary purification and improving the overall dust purification effect of the device.

[0045] In some embodiments, a drawer lock is installed on the collection box 203. The drawer lock cooperates with the first box 201 to detachably fix the collection box 203 inside the first box 201 and prevent the collection box 203 from sliding out when the moving body 1 moves.

[0046] Specifically, the drawer lock cooperates with the first housing 201 to achieve detachable fixing of the collection box 203 inside the first housing 201. When the device moves with the mobile body 1 or when vibration occurs during mining operations, the collection box 203 is locked in a preset position inside the first housing 201 to prevent it from sliding out due to bumps or shaking, thus avoiding secondary pollution caused by the dust collected inside. This ensures that the collection box 203 is always in a collection position connected to the outer shell 401 of the conveying mechanism 4, allowing dust to fall into the collection box 203. Operators can quickly open the drawer lock without the need for special tools, pull the collection box 203 out of the first housing 201 for dust emptying and cleaning, and then push the collection box 203 back to the preset position and lock it with the drawer lock, improving the operational efficiency of maintaining the collection box 203.

[0047] In some embodiments, the second housing 301 is connected to the upper surface of the first housing 201 via support legs. The two ends of the support legs are fixedly connected to the lower surface of the second housing 301 and the upper surface of the first housing 201, respectively, to provide support for the second housing 301 and form an installation spacing.

[0048] Specifically, the two ends of the support legs are fixedly connected to the lower surface of the second housing 301 and the upper surface of the first housing 201, respectively, providing vertical support for the second housing 301. This allows the second housing 301 to be stably mounted above the first housing 201, resisting vibrations and bumps during device movement and operation, preventing the second housing 301 from tilting or loosening, and ensuring the overall stability of the filter mechanism 3. The support legs also create a preset installation distance between the second housing 301 and the first housing 201, providing ample installation space for the housing 401 of the conveying mechanism 4. This allows the conveying mechanism 4 to be smoothly arranged between the first housing 201 and the second housing 301, achieving smooth dust transport. An air passage and component operating space are formed below the second housing 301, preventing interference between the various mechanisms.
