Description

Technical Field

[0001] The present invention relates to a dust collector, in particular to a dust collector based on air cleaning. Background Art

[0002] A large amount of dust will be generated during the cutting and polishing of parts. These dust and exhaust gases have serious impacts on human health and the environment, and may even pose a safety hazard of dust explosion. In addition, some dust can be recycled and reused, which not only reduces air and ground pollution, but also improves resource utilization. For example, metal dust can be collected again after dust removal and can be recycled.

[0003] Traditional dust collectors are divided into dry dust collectors and wet dust collectors. Dry dust collectors have poor dust removal effects on fine particles, including Venturi-based dust collectors and dust collectors that use filter cartridges. These dust removal solutions still have defects in filtering dust that poses a risk of dust explosion, and the filtration efficiency is low. In particular, the filter cartridge filtration solution requires frequent replacement of the filter cartridge, which is cumbersome to use. Wet dust collectors use a spraying solution, which is also prone to poor filtration effects in some cases, and fine dust will re-escape from the air outlet. In order to further improve the filtration effect of wet dust collectors, this application is filed. Summary of the invention

[0021] The present invention will be further described below in detail with reference to the embodiments shown in the accompanying drawings.

[0022] Reference Figure 1-6 As shown, A dust collector based on air cleaning comprises a filter assembly 1 and a negative pressure assembly 2. The negative pressure assembly 2 sucks in air and cooperates with the filter assembly 1 to filter and then sends it out. The filter assembly 1 comprises an air intake mechanism 11, a spray mechanism 12, and a cleaning mechanism 13. The air intake mechanism 11 is connected to the cleaning mechanism 13 and is used to pass the inhaled air and dust mixture into the cleaning mechanism 13. The cleaning mechanism 13 comprises a connecting piece 131 and a plurality of cleaning mesh bags 132 installed on the connecting piece 131. The spray mechanism 12 sprays corresponding to one or more cleaning mesh bags 132. The air sucked into the cleaning mesh bag 132 is cleaned by spraying water mist through the spray assembly, and the dust in the air adheres to the inner wall of the cleaning mesh bag 132 through the water mist and falls down through the water mist washing.

[0023] The negative pressure component 2 is used to drive the air to flow, sucking the air to be filtered into the filter component 1 through negative pressure for filtration, and then sending the filtered air out. The negative pressure component 2 can use a worm gear or a fan to drive the air to be discharged by rotation. The position relative to the filter component 1 will generate negative pressure to suck in the air to be filtered.

[0024] The air intake mechanism 11 is mainly used for the air to be filtered to enter, which can be an opening 1321 or a cover or an interface; the spray mechanism 12 is used to provide water mist, which wets the dust in the air and increases the gravity and adhesion of water to clean the air to be filtered. In the specific work, this scheme first generates negative pressure through the negative pressure component 2, allowing the air to be filtered to enter the position of the cleaning net bag 132 through the air intake mechanism 11, and uses the spray mechanism 12 to spray the cleaning net bag 132 with water mist. The water mist can wet the dust in the air and carry it to the inner wall of the cleaning net bag 132 for attachment. Since the spray mechanism 12 keeps the water mist spraying action, a water flow will be generated on the inner wall of the cleaning net bag 132 at this time, and the dust attached to the cleaning net bag 132 can be washed down by the water flow. The number of cleaning mesh bags 132 in this solution is multiple, which can separate the air to be filtered into multiple smaller channels, and cooperate with the spraying mechanism 12 for spraying, which can make the cooperation between water mist and air better, and reduce the problem of dust in the air being discharged without being wetted and cleaned. This solution can attach dust in the air to the cleaning mesh bag 132 by air cleaning, and fall with the water flow, which can further improve the wet dust collector. There is still a problem that some dust cannot be filtered, such as iron filings and other substances that cannot be dissolved in water. Under the action of negative pressure, there may still be problems of being discharged with the air. The above-mentioned step of using the cleaning mesh bag 132 to cooperate with water mist to treat dust in the air can be understood as cleaning the air.

[0025] It is worth mentioning that when the negative pressure component 2 drives the air to form an airflow, the above-mentioned cleaning net bag 132 will be straightened with the airflow, which can improve the airflow efficiency and can also be in a relatively stable state, and the working process is more controllable.

[0026] The cleaning net bag 132 in this solution has fine meshes and needs to be set according to the actual filtering material. The meshes can be used for airflow to pass through. Part of the gas passes through the meshes, allowing the dust to adhere to the cleaning net bag 132. At the same time, under the action of water mist, it is more stably attached to the cleaning net bag 132. When the nozzle sprays water mist, it will also produce a certain diffusion airflow, which is also helpful for the dust in the air to adhere to the cleaning net bag 132. In addition, with the effect of water mist, the inner wall of the cleaning net bag 132 will remain moist, and the adhesion effect will be better. As the length of the net bag increases, the cleaning and filtering effect will be better. The cleaning net bag 132 in this solution does not need to replace the filter element, and can automatically wash away the dust on the inner wall of the cleaning net bag 132, making it more convenient to use.

[0027] The connecting piece 131 is preferably connected to the inside of the dust collector to form a partition 4, and can relatively seal the upper and lower sides of the connecting piece 131, so that the air to be filtered can better pass through the cleaning net bag 132 and avoid entering the position below the connecting piece 131 without being processed.

[0028] Specifically, one end of the cleaning net bag 132 is installed on the connecting piece 131, and the other end has an opening 1321 for allowing the dust attached to the cleaning net bag 132 to fall down along with the water mist.

[0029] When the cleaning net bag 132 is connected to the connecting piece 131, a flange structure can be used for installation. One end with an opening 1321 is convenient for dust to flow downward with the water flow, and there will be no accumulation problem, thereby further improving the sanitation effect.

[0030] In a preferred embodiment, the cleaning mesh bag 132 is a straight-cylindrical type.

[0031] The straight-cylindrical structure can make the dust flow downward with the water flow more effectively. Since it is a straight-cylindrical structure, the size of the opening 1321 on the cleaning net bag 132 corresponds to the size of the cleaning net bag 132 in a stretched state, which can further increase the efficiency of the dust falling with the water flow.

[0032] As a specific setting scheme, the spray device includes a water pump 121, a water pipe 122, and a plurality of first nozzles 123 arranged on the water pipe 122. The positions of the first nozzles 123 correspond to the cleaning net bags 132. The water pump 121 transports water to the first nozzles 123 through the water pipe 122, and sprays water mist onto the cleaning net bags 132 through the first nozzles 123.

[0033] The number of first nozzles 123 can correspond to the number of cleaning net bags 132. Each cleaning net bag 132 has a first nozzle 123. Multiple first nozzles 123 are installed on the water pipe 122, which is more convenient to arrange. It is only necessary to let the pipe pass through each cleaning net bag 132, and only one water pump 121 is needed to generate water mist at the position of each cleaning net bag 132.

[0034] In addition, in order to allow air to flow through each cleaning mesh bag 132 as evenly as possible, the filter assembly 1 also includes a guide cover 14, which is located above the cleaning mesh bag 132 and is used to cooperate with the air intake mechanism 11 to guide and disperse the air to each cleaning mesh bag 132.

[0035] The air deflector 14 can guide the air entering from the air intake mechanism 11 and disperse the air before it enters the cleaning mesh bag 132 so that the air can pass through each cleaning mesh bag 132 more evenly, and can appropriately reduce the flow rate of the air in each cleaning mesh bag 132, thereby improving the filtering effect.

[0036] As an optional implementation scheme of the air intake mechanism 11, the air intake mechanism 11 includes a connector 111 for cooperating with an external air supply pipeline connection, and the connector 111 is located above the air deflector 14. The filter assembly 1 also includes a second nozzle 112 installed in the connector 111, and the second nozzle 112 is connected to the water pipeline 122 and is used to spray water mist into the connector 111; the air deflector 14 cooperates with the connector 111 to guide the dust flushed down in the connector 111 into each cleaning net bag 132.

[0037] The joint 111 can be connected to an external pipe by a flange or other structure, and the dusty air generated by the external equipment is directly sucked in through the joint 111. When passing through the joint 111, it will first be cleaned by the water mist sprayed by the second nozzle 112, and some dust will be wetted and attached to the inner wall of the joint 111 and fall with the water flow to perform a preliminary cleaning action. After the preliminary cleaning, the deflector 14 is used to guide the flow, and each cleaning net bag 132 is used for secondary cleaning, thereby further improving the cleaning effect. In this solution, a large amount of water mist will be generated during the cleaning process. Before the air enters the cleaning net bag 132, it can be condensed with the help of the diffused water mist and the dust in the air, thereby producing an additional dust reduction effect.

[0038] In a preferred solution, a plurality of through holes are distributed on the air guide cover 14 , and the through holes are used for dust or water to pass through and then fall into the cleaning net bag 132 below the air guide cover 14 .

[0039] On the one hand, the through holes on the air guide cover 14 allow air to pass through, and some dust in the air can be adhered and cleaned due to the moisture on the air guide cover 14. On the other hand, it allows dust or water to pass through and enter the cleaning mesh bag 132 under the air guide cover 14. The setting of the through holes can reduce the obstruction of the cleaning mesh bag 132 under the air guide cover 14, which helps to evenly distribute the airflow in the filter assembly 1.

[0040] In order to facilitate the collection and cleaning of processed dust, the filter assembly 1 also includes a collecting bag 15, which is located below the cleaning net bag 132 and collects the dust washed down from the cleaning net bag 132; and a water reservoir 3 is also provided at the position corresponding to the collecting bag 15, for receiving water filtered by the collecting bag 15; the water pump 121 is used to extract water from the water reservoir 3 and send it into the water pipe 122.

[0041] After the aforementioned cleaning, the dust will flow down with the water flow. By setting up the collection bag 15, the sludge-like dust can be collected and flow into the collection bag 15 along with the flushing of the water flow. It is only necessary to regularly replace the collection bag 15 or clean the collection bag 15 to complete the dust treatment after collection. Moreover, since the internal cleaning net bag 132, the guide cover 14, the joint 111 and other components are in a state of water mist flushing, the interior can maintain a high degree of cleanliness, does not need regular cleaning, is easy to use, and reduces the number of cleaning times.

[0042] In a further configuration, a partition 4 is provided above the water reservoir 3 , and a plurality of through holes are provided on the partition 4 . The collecting bag 15 is placed on the partition 4 , and the filtered water is allowed to fall into the water reservoir 3 through the through holes.

[0043] The partition 4 can be used to support the collecting bag 15 to prevent the collecting bag 15 from being immersed in the water reservoir 3, which helps the water in the collecting bag 15 to drip and drain. It can also provide support for the collecting bag 15 to prevent the collecting bag 15 from being pulled and damaged under the weight.

[0044] The water reservoir 3 in this solution can provide water circulation. The water pump 121 draws water from the water reservoir 3 into the water pipe 122 and sprays it through the nozzle. The water mist condenses into water droplets and flows downward. At this time, it will drip back into the water reservoir 3 after passing through the collection bag 15, and then be recycled. It can be more environmentally friendly and save water resources. On the other hand, it can allow users to use it without being affected by water supply limitations, allowing users to have more choices in placement.

[0045] In order to improve the water circulation efficiency, a dewatering component 5 is also arranged between the negative pressure component 2 and the cleaning net bag 132. The dewatering component 5 includes a plurality of baffles 51, and a retaining edge 52 is arranged on the edge of the baffle 51. The retaining edge 52 is bent downward relative to the baffle 51. The plurality of baffles 51 are combined with each other to form an S-shaped channel between the negative pressure component 2 and the cleaning net bag 132. When the negative pressure component 2 drives the air through the baffle 51, the air contacts the retaining edge 52 to condense water droplets.

[0046] This solution can reduce the amount of moisture carried out of the air after cleaning and filtration. It uses the retaining edge 52 at the edge of the baffle 51 to allow the air to scrape against the retaining edge 52 when flowing in the S-shaped channel formed by multiple baffles 51, and then condense the moisture in the air at this position, further reducing the amount of moisture carried out. This can increase the water circulation time and reduce the rate of moisture reduction in the water reservoir 3.

[0047] The number of filter components 1 or cleaning mechanisms 13 in this solution can be multiple, distributed up and down to form multi-layer cleaning, or the entire device can be connected, so that the air outlet of the previous device is connected to the air inlet of the next device, forming two cleanings.

[0048] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
