DETAILED DESCRIPTION

[0023] The embodiment of the present application will be described in detail below with reference to the drawings.

[0024] As Figures 1-3 In this embodiment, a dust removal tower for preparing filling slurry comprises

[0025] The dust removal tower 10 has an exhaust pipe 11 at the upper end wall and an air inlet pipe 30 at the lower end wall.

[0026] The liquid outlet pipe 20 is arranged at the bottom of the side wall of the dust removal tower 10 and communicates with the dust removal tower 10.

[0027] A plurality of filter screens 40 are arranged on the inner wall of the dust removal tower 10, and are all bowl-shaped inverted and vertically arranged.

[0028] A plurality of liquid collecting pipes 51 are fixedly mounted on the outer wall of the filter screen 40. The liquid collecting pipes 51 have a plurality of spray heads 50, which penetrate the filter screen 40.

[0029] The liquid collecting pipe 51 is fixedly connected to the inner wall of the dust removal tower 10 via a plurality of connecting rods 53;

[0030] A plurality of liquid supply pipes 52 have one end connected to the plurality of liquid collecting pipes 51 and the other end penetrating the side wall of the dust removal tower 10 .

[0031] This embodiment is implemented as follows:

[0032] The exhaust pipe 11 is externally connected to an induced draft fan, and the air intake pipe 30 is externally connected to a dust collection hood.

[0033] When the present application is in use, air enters the dust removal tower 10 from the air inlet pipe 30, and the liquid supply pipe 52 injects clean water into the liquid collecting pipe 51, and then the water is atomized and sprayed out through the spray head 50. The atomized water droplets will come into contact with the dust in the air more comprehensively and absorb the dust, thereby improving the dust reduction effect. At the same time, the filter 40 can block large particles of water droplets and dust, preventing the water droplets from carrying dust and being discharged from the exhaust pipe 11.

[0034] The advantage of the present invention over the prior art is that it has a better dust reduction effect.

[0035] See also Figure 2 、 3 One end of the air inlet pipe 30 extending into the dust removal tower 10 is communicated with the air collecting box 31 , and the air collecting box 31 has a plurality of air outlet pipes 32 .

[0036] By providing the air outlet pipe 32 on the air collecting box 31 , dust can be uniformly introduced into the dust removal tower 10 , thereby improving the dust reduction effect.

[0037] See also Figure 3 , the air outlet pipe 32 is an inverted U-shape.

[0038] The U-shaped air outlet pipe 32 can prevent water mist from directly entering.

[0039] See also Figure 2 The two adjacent filter screens 40 are fixedly connected by a connecting plate 62 , a waterproof cover 61 is fixedly connected to the connecting plate 62 , and a vibrator 60 is fixedly connected inside the waterproof cover 61 .

[0040] The vibrator 60 can drive the waterproof cover 61 to vibrate, and the waterproof cover 61 transmits the vibration to the connecting plate 62, and the connecting plate 62 transmits the vibration to the filter 40, thereby achieving vibration of the filter 40 and preventing the filter 40 from being blocked.

[0041] See also Figure 2The outer wall of the open end of the filter screen 40 is seamlessly connected with the outer wall of the dust removal tower 10 through the annular cloth ring 41.

[0042] Dust can be prevented from passing through the gap between the filter screen 40 and the inner wall of the dust removal tower 10 through the cloth ring 41.

[0043] The above is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the inventive concept of the present application, can make a number of deformation and improvement, these are within the scope of the present application.
