Description

Technical Field

[0001] This utility model relates to the field of dust collector technology, and in particular to a pulse bag dust collector. Background Technology

[0002] A baghouse dust collector is a dry dust filtration device suitable for collecting fine, dry, non-fibrous dust. The filter bags are made of woven filter cloth or non-woven felt, utilizing the filtration effect of the fibrous fabric to filter dust-laden gas. When dust-laden gas enters the baghouse dust collector, large and heavy dust particles settle down due to gravity and fall into the ash hopper. When the gas containing finer dust passes through the filter media, the dust is trapped, thus purifying the gas.

[0003] Existing baghouse dust collectors can reuse the dust they emit by mixing it with the finished powder. However, the dust collected by the dust collector contains a large amount of light materials, which cannot be directly mixed with the finished powder. Separating the dust separately would increase costs and result in low cost-effectiveness. Therefore, how to more conveniently and effectively utilize the dust collected by the dust collector has become an urgent problem to be solved. Utility Model Content

[0004] Given the high cost of dust recycling and reuse in current baghouse dust collectors, this utility model patent provides a pulse baghouse dust collector. By setting a light material filtration device at the dust discharge port, light materials in the dust are filtered out, and the light materials are swept out from the slag discharge port by sliding the brush driven by the handle.

[0005] To achieve the above objectives, the embodiments of this utility model adopt the following technical solutions:

[0006] A pulse jet baghouse dust collector includes a support column on which a baghouse dust collector body is fixed. The dust collector body includes an exhaust gas chamber, a clean gas chamber, a dust discharge port, an air inlet, and an air outlet. The air inlet is connected to the exhaust gas chamber, and the air outlet is connected to the clean gas chamber. The exhaust gas chamber is provided with a plurality of filter bags. The air inlet and the air outlet are both located on the side wall of the dust collector body. A light material filtration device is also provided at the dust discharge port. The main body of the light material filtration device is a single-layer screen fixed at the dust discharge port.

[0007] According to one aspect of the present invention, the light material filtration device further includes a chute, a brush, and a slag discharge port, wherein the chute and the slag discharge port are both located outside the powder and ash discharge port.

[0008] According to one aspect of the present invention, a handle is fixedly connected to the top of the brush, and the handle is slidably connected to the slide groove, thereby driving the brush to clean the single-layer screen.
