Description

Technical Field

[0001] The utility model relates to the technical field of milk powder production equipment, in particular to a dust removal device used for producing milk powder. Background Art

[0002] A large amount of dust will be generated during the production process of milk powder. If the dust is not absorbed and removed in time, it will easily cause harm to the workers. Therefore, dust removal equipment is used in conjunction with the production process of milk powder.

[0003] The existing dust removal device for producing milk powder extracts air so that the dust contained in the air is filtered and adsorbed through a filter element. The filtration effect of adsorption through the filter element alone is poor, and some dust will still return to the air. The quality of dust removal is low, and the filter element needs to be cleaned manually and regularly, and the operation is cumbersome and complicated. If it is not cleaned in time, it is easy to cause blockage, affecting the dust removal efficiency.

[0004] For example, a dust removal device for producing milk powder disclosed in Chinese patent CN215506161U is used. By turning on the first exhaust fan, the dust-containing air enters the bent pipe through the exhaust hopper and enters the dust box through the air inlet pipe. The bent pipe is not on the same axis as the dust box, which can effectively prevent the dust in the dust box from falling back to the outside and causing secondary pollution. The dust-containing air enters the dust box under the pumping of the first exhaust fan and continues to float upward until it is blocked by the filter plate at a position parallel to the anode electrode. The anode electrode and the cathode electrode are parallel to each other. The high-voltage electrostatic field generated by the anode electrode electrically separates the dust-laden air. After the dust particles combine with negative ions and carry negative charges, they tend to discharge toward the surface of the anode electrode and are adsorbed by the anode electrode. The dust collection effect is good and the work quality is effectively improved. After the dust collection is completed, the power supply to the anode electrode and the cathode electrode is disconnected, and the dust adsorbed on the surface of the anode electrode automatically settles into the dust box through the dust collecting pipe. The lower dust box is rotated to centrally process the collected dust. There is no need for manual and uninterrupted cleaning of the dust collection box, which saves time and effort and effectively improves work efficiency.

[0005] However, the dust removal device proposed in the above comparative example, after using the electrostatic field generated by the positive and negative electrodes to adsorb the dust, when the power is turned off to allow the dust to fall into the collection box, the dust is easily adsorbed inside the filter box due to the influence of the electrostatic field, and is easy to stick and not fall completely into the collection box.

[0006] For this reason, we urgently need to provide a dust removal device for producing milk powder. Utility Model Content
