Referring to fig. 1-6, an embodiment of a waste gas treatment device of a concrete mixing plant of the present invention includes a box body 1 with openings at upper and lower ends; the air extracting device 2 is arranged at an opening at the upper end of the box body 1; the mounting plate 3 is arranged in the box body 1; the filter cartridges 4 are uniformly distributed on the mounting plate 3; the pulse generator 5 is arranged outside the box body 1, and the output end of the pulse generator 5 is arranged above the filter cartridge 4; wherein, a mounting frame 6 is arranged in the box body 1, an elastic piece is arranged at the upper end of the mounting frame 6, the lower end of the elastic piece 7 is fixed on the upper end surface of the mounting frame 6, and the upper end is fixed on the lower end surface of the mounting plate 3; the elastic element is a spring.

When the air with dust is pumped out by the air pumping device 2, the dust is adsorbed on the filter cylinder 4, a large amount of dust is adsorbed on the filter cylinder 4 after long-time work, at this time, the air pumping device 2 is stopped, the pulse generator 5 is opened, high-pressure airflow is output to the adsorption cylinder 7, and the dust on the filter cylinder 4 is blown off; in the process, because the output end of the pulse generator 5 outputs airflow downwards all the time, certain pressure is generated on the mounting plate 3, the elastic part absorbs the pressure, and then after the pulse generator 5 stops working, the elastic part releases the absorbed pressure to drive the mounting plate 3 to vibrate up and down, so that the filter cartridge 4 arranged on the mounting plate 3 is vibrated up and down, dust which cannot be blown off by the airflow can be vibrated down, and the dust removal effect is improved; and the spring can be according to the multi-direction atress of self deformation for mounting panel 3 not only wholly vibrates from top to bottom, can also make the up end of mounting panel 3 take place the slope, produces slight rocking.

The mounting plate 3 includes a connection frame 31, an inner plate 32, and a flexible plate 33 disposed between the connection frame 31 and the inner plate 32; the filter cartridge 4 is mounted on the inner plate 32; the flexible plate 33 is made of rubber.

The box 1 of this device is the cuboid, when the air current applyed pressure for mounting panel 3, at first the flexible sheet 33 takes place to deform, then the pulling spring takes place to deform, has better suitability comparing direct compression spring to flexible sheet 33 and spring synchronization work increase the range of inner panel 32 vibration from top to bottom when the effort is rebounded.

The output end of the pulse generator 5 comprises an air duct 8, and the lower end of the air duct 8 is provided with a spray head 9 corresponding to the position of the filter cartridge 4; a bronchus 10 is arranged between the air ducts 8, and a spray head 9 is also arranged in the middle of the bronchus 10.

The nozzles 9 located on the branch pipes 10 can directly blow high-pressure air flow towards the inner plate 32, so that the upper surface of the mounting plate 3 can be cleaned, and the acting force on the mounting plate 3 can be increased, so that the amplitude of the up-and-down vibration of the whole of the filter cartridges 4 is increased.

One end of the bronchus 10 is communicated with the air duct 8 at the front, and the other end is arranged on the outer surface of the air duct 8 at the rear in a sealing way.

The quantity of air duct 8 is four in this device, because air exhaust device 2 sets up the one side at box 1, so the air current can remove to air exhaust device 2's direction, will cause the area and the time of a row of filter cylinder 4 contact air current that is close to air exhaust device 2 great like this, so when removing dust, the word need open be close to air exhaust device 2 air duct 8 can, cooperation bronchus 10 can remove dust to filter cylinder 4 equally, can also reduce the energy consumption cost.

The diameter of the air outlet of the spray head 9 positioned on the bronchus 10 is smaller than that of the air outlet of the spray head 9 positioned on the air duct 8.

The control of the air outlet enables the pressure output by the nozzle 9 on the branch pipe 10 to be higher, and the subsequent vibration amplitude of the mounting plate 3 can be increased.

One end of the air duct 8, which is far away from the pulse generator 5, is fixed in the box body 1.
