Description

Technical Field

[0001] The utility model relates to the technical field of powder feeding production equipment, in particular to a cloth bag dust removal device for a feeding dust bin. Background Art

[0002] In industrial production, powdered materials are more common. Dust dispersion is most likely to occur during the bagging process of powdered materials. To address this phenomenon, most existing workshops use a fan negative pressure method in a certain space. However, for spaces with high dust density, the use of fans for adsorption often causes excessive dust adhesion, resulting in unsatisfactory dust removal effects. Therefore, bag dust removal devices are gradually used for dust recovery operations.

[0003] The existing technology has the following problems:

[0004] The bags in existing bag-type dust removal devices are generally distributed in a rectangular array in the dust removal device, resulting in that during dust removal operations, the bags close to the dust inlet can filter the dust, while the bags far away from the dust inlet cannot fully filter the dust due to the dust blocking by the bags close to the dust inlet. As a result, the bags near the dust inlet are severely damaged during use, and the bags near the dust inlet often need to be replaced.

[0005] To this end, we proposed a bag dust removal device for feeding dust silo to solve the above-mentioned drawbacks. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art that the cloth bag far away from the dust inlet is unable to fully filter the dust due to the blocking of the dust by the cloth bag close to the dust inlet, which leads to serious damage to the cloth bag close to the dust inlet and the need to replace the cloth bag close to the dust inlet frequently. A cloth bag dust removal device for a feeding dust bin is proposed to solve the problem that the cloth bag close to the dust inlet is far away from the dust inlet, and the dust is blocked by the cloth bag close to the dust inlet, so that the dust cannot be fully filtered, which leads to serious damage to the cloth bag close to the dust inlet and the need to replace the cloth bag close to the dust inlet frequently.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a feeding dust silo bag dust removal device, comprising a feeding silo and a dust removal box, a dust suction head is installed on the upper surface of the feeding silo, the dust removal box is installed on the dust suction head through a pipeline, and a fan is installed on the upper surface of the dust removal box, and an exhaust pipe is arranged on the upper surface of the fan, a support plate is obliquely arranged inside the dust removal box, filter holes are opened on the surface of the support plate, and a support frame is installed at the filter hole through a bearing, and a dust removal bag is arranged on the surface of the support frame.

[0009] Preferably, a transmission wheel is provided on the surface of the rotating rod, and a belt is provided between adjacent transmission wheels.

[0010] Preferably, the dust removal bags are provided in multiple groups, and the multiple groups of dust removal bags are arranged in a stepped structure.

[0011] Preferably, an air tank is mounted on the side surface of the dust removal box via a mounting seat, and a ventilation pipe is connected to the air outlet of the air tank, and a nozzle is mounted on the lower surface of the ventilation pipe, and the nozzle is arranged corresponding to the dust removal bag.

[0012] Preferably, an inspection door is installed on the front of the dust removal box through a hinge, and a sealing gasket is provided on the inner side of the inspection door.

[0013] Preferably, a discharge port is provided on the lower surface of the dust removal box, and a sealing cover is provided at the discharge port.

[0014] Preferably, the lower surface of the dust removal box is provided with legs.

[0017] (1) The utility model is provided with a feeding bin, a dust collecting box, a dust collecting head, a fan, an exhaust pipe, a support plate, a filter hole, a support frame and a dust collecting bag. When in use, the fan is started to apply negative pressure to the interior of the dust collecting box, so that the dust at the feeding bin enters the dust collecting shell along the air, and the powdery materials in the air are filtered by the dust collecting bag. Since the support plate is inclined, the support frame and the dust collecting bag are stepped, and the dust collecting bags are all on the windward side of the dust, so that all the dust collecting bags can filter the dust.
