Description

Technical Field

[0001] The utility model relates to the technical field of traction frames, in particular to a dust removal device for a fertilizer production workshop. Background Art

[0002] Fertilizers can provide one or more essential nutrients for plants, improve soil properties, and increase soil fertility. They are one of the material bases for agricultural production. In the production process of fertilizers, a large amount of waste gas is generated, which contains particulate impurities and harmful gases, so dust removal is required.

[0003] The dust removal device for fertilizer production workshop described in Publication No. CN211159108U saves a lot of working space by integrating the filtering device and the purification collective device in a dust removal box; by setting the filtering baffle, when the smoke enters the dust removal chamber, large particles are blocked by the filtering baffle and fall into the ash hopper, and will not enter the dust removal chamber with the gas; the arrangement of the filter bags is designed to be a surrounding type according to the shape of the dust removal chamber cavity, which can make full use of the space in the dust removal chamber; by setting a vibration motor, the vibration motor drives the flower plate to vibrate and then drives the filter bag to vibrate, so that the tiny particles in the smoke will not adhere to the filter bag too much and affect the subsequent filtering process; by setting a pulse air pipe, the filter bag can be backblown so that the smoke dust particles can be blown off the filter bag and fall into the ash hopper; by setting an activated carbon filter, the odor of the gas in the workshop can be removed, but the prior art still has defects:

[0004] 1. The prior art absorbs smoke and dust particles by installing filter bags on the flower plates, and makes the dust on the filter bags fall off through the vibration motor and the pulse air pipe. However, after long-term use, the smoke and dust particles on the filter bags cannot be completely dropped by this method, and a large amount of residues will still be contaminated. Since the prior art filter bags and the flower plates are inconvenient to disassemble and install, it is difficult to replace them effectively, which affects the filtering efficiency.

[0005] 2. In the prior art, polluted air enters from the air inlet and is sucked out by a suction fan after being filtered. However, since the prior art sets a pulse air pipe to blow air downward in the opposite direction of the air intake, the airflow becomes turbulent and the polluted air rises directly from the gaps next to it without being filtered by the filter bag, resulting in low dust removal efficiency.
