The two side ends of the mounting frame 61 are detachably connected to the dust removal box 1 through a snap-on structure. A handle 64 located on the outside of the dust removal box 1 is welded to one end of the mounting frame 61. The handle 64 is used to pull the mounting frame 61. Rectangular grooves 18 are symmetrically provided on both sides of the inner wall of the mounting frame 61.

[0030] When in use, the connecting pipe 14 guides the dust-containing air after preliminary purification into the interior of the purification chamber 3, and at the same time, the water pump 92 is turned on to pump the water source inside the water tank 91 into the interior of the diversion pipe 95 through the water pipe 93, and then out through the spray head 94, so as to wet the dust in the gas and make it fall on the top surface inside the purification chamber 3, and then flow out from the interior of the purification chamber 3 through the drain port, and the clean gas flows upward through the activated carbon adsorption plate 15 for further purification, and the treated gas is discharged through the outlet pipe.

[0031] Working principle: When the dust removal device for fertilizer production is to be used, first move the device to the vicinity of the production equipment through the pulley 10 and the pusher 11, so that one end of the air inlet pipe 4 is aligned with the discharge port, and then start the suction fan 13 to pump the dust-carrying gas into the interior of the dust suction chamber 2 through the air inlet pipe 4, and at the same time start the motor 51 to drive the cleaning component to run and continuously clean the surface of the screen 12. The dust-carrying gas passes through the filter 62 and the electrostatic dust collecting net 63 and enters the interior of the purification chamber 3 through the connecting pipe 14 after preliminary filtration in turn, and then start the water pump 92 to spray the water source in the water tank 91 from the spray head 94 through the water pipe 93 and the diversion pipe 95, so as to wet the dust in the gas and make it fall into the interior of the purification chamber 3. On the top surface, the clean gas flows upward and passes through the activated carbon adsorption plate 15 for further purification, and then is discharged from the interior of the purification chamber 3 from the exhaust pipe. When the filter assembly needs to be disassembled, the user pulls the handle 64 by hand to drive the installation frame 61 to move, so that the snap-on structure is operated, thereby releasing the limit fixation of the installation frame 61, and then the installation frame 61 can be pulled out from the interior of the dust suction chamber 2, and then force is applied to the filter screen 62 and the electrostatic dust collecting screen 63 in turn so that the resistance block 72 drives the resistance spring 71 to undergo elastic compression deformation, thereby taking the filter screen 62 and the electrostatic dust collecting screen 63 out from the interior of the installation frame 61, and the filter screen 62 and the electrostatic dust collecting screen 63 can be replaced. It is easy to use and improves the efficiency of disassembly work.
