Description

Technical Field

[0001] The utility model relates to the field of dust waste collection, in particular to an automatic polishing dust recovery device. Background Art

[0002] In modern manufacturing, wheel hub grinding is a common process. However, grinding wheel hubs will generate a large amount of waste dust, which will not only pollute the working environment, but also may cause harm to the health of workers. In addition, if the waste dust is not effectively collected and treated, it will also affect the normal operation of the equipment.

[0003] At present, common waste dust collection methods include using ventilation equipment to extract dust and discharge it into the atmosphere, or using equipment such as bag dust collectors for filtering and collection. However, these methods have some limitations. Ventilation equipment may not be able to completely capture all dust, resulting in some dust still being scattered in the working environment. Filtering equipment such as bag dust collectors require regular cleaning and replacement of filters, which increases maintenance costs and work difficulty.

[0004] At present, a Chinese utility model patent application with publication number CN207629856U and publication date of November 16, 2017 proposes a double-station water-washing wheel hub grinding system, including: a water supply system, a spray system, an exhaust filtration system, a water curtain wall, and a double-station grinding platform. The water supply system is connected to the spray system and the water curtain wall pipeline. The water supply system supplies water to the spray system to form water mist and to the overflow trough at the top of the water curtain wall to form a waterfall-like water curtain on the water curtain wall; the exhaust filtration system and the spray system are connected through an exhaust fan, and the dust after adsorption by the water curtain and the spray is sent to the exhaust filtration system by the exhaust fan for filtration again and then discharged to the outside; the double-station grinding platform is arranged on both sides of the water curtain wall, and the spray system is arranged between the two water curtain walls.

[0005] The spray mechanism forms a water curtain, a water curtain, and a strong mixture of water mist in the air-water channel, forming a multi-stage purification process to purify waste dust in the air and remove dust in the air.

[0006] With regard to the above-mentioned related technologies, dust waste in the air is absorbed and purified by means of water curtains and water curtains. Although the purification effect is improved to a certain extent, a large amount of sewage will be generated after the purification process, which increases the burden of subsequent sewage treatment. At the same time, the water curtains and water curtains will impact the slag scavenging pool, making it difficult for the waste slag formed by the dust in the slag scavenging pool to gather, increasing the difficulty of waste slag salvage and treatment.

DETAILED DESCRIPTION

[0042] The utility model discloses an automatic polishing dust recovery device. Figure 1 and Figure 2 A polishing dust automatic recovery device mainly includes a conveying mechanism 100, a purification mechanism 200 and a recovery mechanism 300 for recovering waste slag. The purification mechanism 200 is arranged on the conveying mechanism 100. The dust exhaust gas is conveyed by the conveying mechanism 100, and then the dust exhaust gas is purified by the purification mechanism 200. Then the purified air is discharged through the conveying mechanism 100. The waste slag blocks generated after purification enter the recovery mechanism 300 for centralized recovery, which reduces the difficulty of collecting the waste slag blocks and improves the recovery efficiency.

The input component 110 includes a collection cover 111 and a feed pipe 112. The collection cover 111 is fixedly mounted on the feed pipe 112 by bolts. The end of the feed pipe 112 away from the collection cover 111 is fixedly mounted on the purification mechanism 200 by bolts. The discharge component 120 includes a discharge pipe 121, a first filter 122, a fan 124, a drive motor 125 and a second filter 123. One end of the discharge pipe 121 is fixedly mounted on the purification mechanism 200 by bolts. The first filter 122 is fixedly mounted on the end of the discharge pipe 121 close to the purification mechanism 200 by bolts. The fan 124 is rotatably mounted in the discharge pipe 121. The drive motor 125 is fixedly mounted on the discharge pipe 121 by bolts. The fan 124 is transmission-connected to the output end of the drive motor 125. The second filter 123 is arranged at the end of the discharge pipe 121 away from the first filter 122.

[0044] The driving motor 125 drives the fan 124 to rotate, so that the collection cover 111 can suck the dust at the collection position into the feed pipe 112. After the dust is purified by the purification mechanism 200, the air is filtered through the first filter 122 and then discharged through the exhaust pipe 121, which improves the efficiency of collecting dust. At the same time, the remaining purified water mist after purification can clean the first filter 122, so that the first filter 122 maintains good filtering performance. The second filter 123 filters the gas filtered by the first filter 122, further reducing the possibility of dust in the exhaust gas and improving the filtering effect.

One end of the liquid inlet pipe 212 is connected to the atomizing nozzle 211, and the other end of the liquid inlet pipe 212 is connected to the water source. The booster pump 213 is installed on the liquid inlet pipe 212;

[0047] When dust waste enters the purification box 201 through the feed pipe 112, the water used for purification is pressurized by the booster pump 213 and then sprayed out in the form of fine water mist through the atomizing nozzle 211. The water mist contacts the dust and falls to form deposited waste residue, saving the amount of water used for purification and reducing the possibility of generating sewage. The water mist that has not contacted the dust and the purified air are discharged through the conveying mechanism 100, reducing the excessive pollution of the water used for purification.
