Description

Technical Field

[0001] The utility model relates to the technical field of powder coating processing equipment, in particular to a dust removal device with a low air resistance structure. Background Art

[0002] Powder coating is a new type of solvent-free solid powder coating. Compared with liquid coating, it has the characteristics of solvent-free, pollution-free, and high mechanical strength of the coating film due to its fewer raw material components and no solvent volatilization. It is widely used in various industries such as home appliances.

[0003] The mixing of the various components of the powder coating requires a mixer. After mixing, the mixer discharges the materials into the lower hopper, and then the materials enter the extruder for melt mixing. In the process of discharging the materials into the lower hopper after mixing, a large amount of dust will be generated. The powdery materials will fly a lot, and a small amount of materials will be scattered on the ground, polluting the environment and affecting the health of the workers. Therefore, a dust removal device needs to be installed, and the air resistance of the dust removal device affects the flow of gas, which will cause incomplete dust removal. Utility Model Content

[0004] The purpose of the utility model is to provide a dust removal device with a low air resistance structure to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a dust removal device with a low air resistance structure, comprising a dust removal hood, a suction pipe detachably installed between the dust removal hood and the discharge pipe of the hopper, a first exhaust fan and a second exhaust fan are respectively installed on the upper and lower parts of the suction pipe, the air inlet ends of the first exhaust fan and the second exhaust fan are both provided with powder filters, and purification pipes are detachably installed on the air outlet ends, and a purifier is installed at the air outlet of the purification pipe.

[0006] A guide block is arranged at the turning point of the extraction pipe.

[0007] The guide block is an arc-shaped block.

[0008] The air outlet end of the purifier is equipped with an air flow expansion section.

[0009] The airflow expansion section is a trumpet-shaped structure.

[0010] Compared with the prior art, the beneficial effects achieved by the utility model are as follows: the utility model installs a dust removal hood between the mixer and the hopper, and connects the dust removal hood with the discharge pipe of the hopper through a suction pipe, so that the powder particles can be pumped into the hopper for further discharge. On the one hand, dust is eliminated, the environment of the production area is protected, and the health of the staff is guaranteed. On the other hand, material waste is avoided and production costs are reduced. A purification pipe is arranged on the outside of the suction pipe, and the purification pipe is installed on two exhaust fans. A purifier is installed at the air outlet of the purification pipe. This design allows the extracted gas to be purified again before being discharged, which greatly improves the cleanliness of the exhausted gas and minimizes the pollution to the environment. A guide block is arranged at the turning point of the suction pipe to reduce air resistance and ensure that the dust is removed cleanly. BRIEF DESCRIPTION OF THE DRAWINGS
