Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to an explosion-proof device for a central dust collector. Background Art

[0002] During the grinding process of workpieces in the factory, sparks will be generated due to the friction of the grinding wheel. When the sparks touch the air with high dust content, an explosive reaction will occur, thereby damaging equipment and human body. If the dust remains in the air and is directly inhaled by the human body, it will directly endanger the health of the workers.

[0003] The prior art also has the following defects during use:

[0004] The filtration level of the dust collector in the prior art is low, which generally allows large particles to directly enter the dust collector, causing waste accumulation inside the dust collector and affecting the operation of the equipment. At the same time, since the air where the dust collector is located may have a certain temperature, the overly high temperature air may burn the internal structure of the dust collector;

[0005] Dust collector equipment in the prior art is generally used in safe areas, but different dust collectors are needed for some special high-dust areas. High-dust areas are very likely to cause explosions when encountering open flames. If the dust collector is not well prepared for explosion-proof in this area, the device is very likely to be damaged.

[0006] In view of this, we propose a central dust collector explosion-proof device to solve the existing problems. Utility Model Content

[0009] Preferably, an air collecting hood is installed on one side of the top of the air inlet transverse duct near the first filter.

[0010] Preferably, the first fans are provided with two groups, and the blades of the first fans are oriented inwards, and the blades of the second fans are oriented downwards.

[0011] Preferably, one end of the liquid inlet pipe passes through the purified liquid surface and the purified liquid carrying plate to connect to the cooling space, and the other end of the liquid inlet pipe extends to the interior of the purified liquid.

In the high-dust area, a large explosion may occur when encountering an open flame. The dust collector with explosion-proof preparation will be able to avoid damage here.
