Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, and more specifically to a self-excited wet dust collector. Background Art

[0002] When polishing and grinding the outer surface of the workpiece, dust will be generated. Dust floating in the air will pollute the environment and seriously endanger the health of workers. Some dust can even cause explosions. Therefore, it is necessary to use a dust collector to deal with dust. Dust collectors are divided into dry dust collectors and wet dust collectors. Among them, wet dust collectors are more widely used. Wet dust removal is a method of using water to fully contact with dust-containing gas to wash away dust particles and purify the gas. It is particularly suitable for treating high-temperature, high-humidity, flammable and explosive dust-containing gases.

[0003] Traditional wet dust collectors use water pumps to supply water for spraying (that is, water is pumped into the wet dust collector through pipes using a water pump for spraying and dust removal). However, the washing liquid becomes dirtier and dirtier as the dust removal time increases, which can cause the water pump to become clogged and shorten its service life. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, a self-excited wet dust collector comprises a shell 1 and a fan 2 arranged above the shell 1, the interior of the shell 1 is divided from top to bottom into a fan 2 installation area, a filter area 4 and a water mist area 5, the shell 1 is provided with dust inlets 51 on both sides of the water mist area 5, the shell 1 is provided with a dust collecting groove 52 in the middle of the bottom surface of the water mist area 5, a screed plate 53 is provided at a position between the dust inlet 51 and the dust collecting groove 52 in the water mist area 5, a plurality of screed teeth 531 are evenly spaced at the bottom of the screed plate 53, a water inlet groove 6 is provided on one side of the water mist area 5 of the shell 1, a partition 7 is provided between the water inlet groove 6 and the water mist area 5, a gap 71 is provided at the bottom of the partition 7 to allow water to flow between the water inlet groove 6 and the water mist area 5, a water baffle 72 is provided below the position of the partition 7 corresponding to the dust collecting groove 52, and a gap 73 is formed between the water baffle 72 and the partition 7, A dust bag 8 is detachably provided at a position corresponding to the gap portion 73 of the water inlet trough 6; the dust collecting trough 52 is composed of two baffles 521 and the side of the shell 1; the two baffles 521 are inclined in opposite directions, and the width of the opening formed by the two baffles 521 is smaller than the bottom width of the dust collecting trough 52; an installation opening frame is provided above the dust collecting trough 52, and a filter plate 91 that can be removed and replaced is placed on the installation opening frame, and the opening of the installation opening frame is in the shape of a trumpet with a larger top and a smaller bottom; a spacing filter plate layer 92 is provided above the installation opening frame, and the spacing filter plate layer 92 separates the filter area 4 and the water mist area 5, and the spacing filter plate layer 92 is configured as a cyclone filter plate 93 or a cyclone filter plate 93 is provided in the spacing filter plate layer 92; a socket frame 61 is provided on one side of the partition 7 of the water inlet trough 6, and the dust bag 8 is inserted in the socket frame 61, and a water inlet pipe 62 is provided outside the water inlet trough 6.

[0022] By adopting the above technical solution, in the present utility model, when in use, water first flows from the water inlet pipe 62 into the housing 1, specifically, the water will first flow into the water inlet groove 6, and then flow into the water mist area 5 of the housing 1 through the gap 71 (specifically, the water will flow to the position of the water mist area 5 except the dust collecting groove 52). As the polishing and grinding proceed, dust will enter the water mist area 5 from the dust inlet 51. First, due to the setting of the material leveling plate 53, the dust will be evenly divided by the material leveling teeth 531 when passing through the material leveling plate 53 and enter the upper part of the dust collecting groove 52. Since the upper part of the dust collecting groove 52 directly faces the suction force of the fan 2, the water mist and the dust are fully in contact above the dust collecting groove 52, and the dust-carrying water vapor with larger particles will directly fall into the dust collecting groove 52, and the other dust-carrying water vapor will pass through the filter plate 91 and the interval filter plate layer 92 to adsorb and filter the dust, so that the installation area of ​​the fan 2 can always be kept dry.

[0023] As the dusty water (i.e., sewage) in the dust collecting groove 52 slowly accumulates, when the accumulated height exceeds the height of the water baffle 72, the dusty water will pass through the gap 73 and enter the dust collecting bag 8. The dust collecting bag 8 is preferably a bag or a cover with mesh holes on the surface, and the dust collecting bag 8 is detachably mounted or inserted in the socket frame 61, so that it is convenient to clean and replace the dust collecting bag 8. And because the dust collecting bag 8 has mesh holes, the sewage passing through the dust collecting bag 8 will be filtered by the dust collecting bag 8, and the impurities will remain in the dust collecting bag 8, and the filtered water will enter the water inlet groove 6, and then enter the water mist area 5 to be driven by the fan 2 to splash for re-adsorption of dust, so as to achieve the purpose of recycling.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
