[0027] Example 1 like Figures 1 to 3 、 Figure 5As shown, the present invention provides a dust removal device for premixed mortar, comprising a dust removal box 1; a rotating drum 2 is rotatably arranged in the dust removal box 1, and a dust inlet 11 is provided on the side wall of the dust removal box 1 away from the rotating drum 2; an L-shaped air outlet 3 is provided below the rotating drum 2, and the vertical end of the L-shaped air outlet 3 is located on the bottom surface of the dust removal box 1, and the horizontal end of the L-shaped air outlet 3 is located on the side wall of the dust removal box 1 away from the dust inlet 11; a spray pipe assembly 4 is provided on the outer peripheral wall of the rotating drum 2; a liquid-gas separation box 5 is provided Outside the dust removal box 1, the horizontal end of the L-shaped air outlet 3 is connected to the liquid-gas separation box 5, and the liquid-gas separation box 5 is connected to the filter cartridge 6 arranged outside the liquid-gas separation box 5 through the air guide pipe 51.

The filter water tank 7 is connected to the spray pipe assembly 4 through a hose.

[0028] The external dust enters the dust box 1 through the dust inlet 11 (a suction fan can be provided near the dust inlet 11 in the dust box 1 to facilitate the entry of external dust; at the same time, a filter plate can be provided in the dust box 1 to facilitate preliminary filtration of the dust, which is beneficial to reduce the blockage of the filter water tank 7); the dust entering the dust box 1 enters through the horizontal end of the L-shaped air outlet 3 and is then discharged from the vertical end of the L-shaped air outlet 3. At the same time, the spray pipe assembly 4 is started to spray the dust discharged from the vertical end of the L-shaped air outlet 3. The dust and spray water after spraying treatment enter the liquid-gas separation box 5: the dust in the liquid-gas separation box 5 can enter the filter cartridge 6 through the air guide pipe 51, and then be filtered and discharged under the action of the filter plug 62; the spray water in the liquid-gas separation box 5 enters the filter water tank 7 through the filtrate cartridge 71 (the filter water tank 7 is provided with a water pump connected to the hose, and the water in the filter water tank 7 can be sprayed out through the hose through the spray pipe assembly 4 to spray the dust), and can enter the spray pipe assembly 4 through the hose for circulating spraying use.

[0029] Example 2 Based on the first embodiment, Figures 1 to 6As shown, the drum 2 includes a drive motor 21, which is arranged on the outer wall of the dust removal box 1; the cylinder 22 is coaxially arranged on the output shaft of the drive motor 21, and the cylinder 22 is a hollow structure. The filtered water tank 7 is connected to the cylinder 22 through a hose, and the spray pipe assembly 4 is arranged on the outer peripheral wall of the cylinder 22; the spray pipe assembly 4 includes a spray trough 41, and a plurality of nozzles 411 are arranged on the spray trough 41 along the length direction. The nozzle 411 is located above the vertical end of the L-shaped air outlet 3, and the nozzle 41 1 faces the bottom surface of the dust removal box 1; a plurality of spray slots 42 are provided, and the plurality of spray slots 42 are arranged in parallel on the outer peripheral wall of the cylinder 22 in sequence, and a plurality of spray heads 421 are provided on the spray slot 42 along the length direction, and the spray head 421 is located above the horizontal end of the L-shaped air outlet 3, and the spray head 421 faces the horizontal end of the L-shaped air outlet 3; the spray slot 1 41 and the spray slot 2 42 are circumferentially arranged on the outer peripheral wall of the cylinder 22, and the spray slot 1 41 and the spray slot 2 42 are both connected to the interior of the cylinder 22.

[0030] According to the content of particles in the dust, the driving motor 21 is started to drive the cylinder 22 to rotate, so that the directions of the nozzle 1 411 on the spray trough 1 41 and the nozzle 2 421 on the spray trough 2 42 can be adjusted (that is, when the nozzle 1 411 on the spray trough 1 41 is directed toward the bottom surface of the dust removal box 1, the spray trough 2 42 is directed toward the horizontal end of the L-shaped air outlet 3; when the nozzle 1 411 on the spray trough 1 41 is directed toward the horizontal end of the L-shaped air outlet 3, the nozzle 2 42 on the spray trough 2 42 is directed toward the horizontal end of the L-shaped air outlet 3). The spray water in the filtered water tank 7 enters the cylinder 22 through the hose, and is then sprayed out by the nozzle 1 411 through the spray slot 1 41 (or sprayed out by the nozzle 2 421 through the spray slot 2 42) so as to achieve different spraying effects on the dust (since the number of the spray slots 2 42 is greater than the number of the spray slots 1 41, the water volume and spraying density sprayed by the nozzle 2 421 are greater than the water volume and spraying density sprayed by the nozzle 1 411).

[0031] When nozzle 1 411 (or nozzle 2 421) is directed toward the bottom surface of the dust removal box 1, dust particles adhering to the bottom surface of the dust removal box 1 can be flushed. The bottom surface of the dust removal box 1 is inclined, and the spray water after flushing can pass through the lower end of the dust inlet 11 (a drainage hole can also be provided below the dust inlet 11); when nozzle 1 411 (or nozzle 2 421) is directed toward the horizontal end of the L-shaped air outlet 3, different spraying treatment effects can be achieved on the dust.

[0032] Example 3 Based on the first embodiment, Figure 1 、 Figures 7 and 8As shown, an inverted cone 52 is provided on the bottom surface of the liquid-gas separation box 5, and a filtrate cylinder 71 is vertically provided on the top of the filter water box 7. The upper and lower ends of the inverted cone 52 and the upper and lower ends of the filtrate cylinder 71 are both open, and the small diameter end of the inverted cone 52 corresponds to the top opening position of the filtrate cylinder 71 above and below; the inverted cone 52 and the filtrate cylinder 71 are coaxial; the filter cylinder 6 is horizontally provided outside the liquid-gas separation box 5, and the filter plug 62 includes an inverted L-shaped guide rod 621, and the vertical end of the inverted L-shaped guide rod 621 is coaxially provided in the filtrate cylinder 71 The horizontal end of the inverted L-shaped guide rod 621 is coaxially arranged in the filter cylinder 6; there are multiple conical filter plugs 622, which are movably arranged in the filtrate cylinder 71, and the multiple conical filter plugs 622 are distributed in sequence along the direction of the vertical end of the inverted L-shaped guide rod 621; the pushing cylinder 623 is arranged outside the horizontal end of the inverted L-shaped guide rod 621, and the movement direction of the piston rod of the pushing cylinder 623 is the same as the length direction of the horizontal end of the inverted L-shaped guide rod 621, and the piston rod of the pushing cylinder 623 conflicts with the conical filter plug 622.

[0033] After the dust and spray water are sprayed into the liquid-gas separation box 5, the spray water can enter through the large diameter end of the inverted cone cylinder 52 and then enter the filtrate cylinder 71 through the small diameter end of the inverted cone cylinder 52. It can be filtered by the conical filter plug 622 and then flow into the filtered water tank 7, so that the spray water filtered by the conical filter plug 622 in the filtered water tank 7 can be recycled.

[0034] The dust and spray water after spraying enter the liquid-gas separation box 5, wherein the dust after spraying can enter the filter cartridge 6 through the air guide pipe 51 (because the air guide pipe 51 is connected and arranged in the filter cartridge 6 away from the pushing cylinder 623, the exhaust pipe 61 is connected and arranged in the filter cartridge 6 close to the pushing cylinder 623 end, and at the same time, a plurality of frustum filter plugs 622 are arranged in sequence along the horizontal end of the inverted L-shaped guide rod 621 in the filter cartridge 6, so after the dust enters the filter cartridge 6, it can pass through each frustum filter plug 622 in sequence along the direction of the horizontal end of the inverted L-shaped guide rod 621 for filtration, and the filtered dust is finally discharged through the exhaust pipe 61); after the various frustum filter plugs 622 in the filter cartridge 6 have been used for a period of time, the pushing cylinder 623 can be started to move the frustum filter plugs 622 located at the filter cartridge 6 to the filter cartridge 6. The conical filter plugs 622 on the outside of the cylinder 6 are pushed into the filter cylinder 6 in turn, and at the same time, the used conical filter plugs 622 in the filter cylinder 6 can be gradually pushed out. Since the inner diameter of the filter cylinder 6 is the same as the inner diameter of the filtrate cylinder 71, the conical filter plugs 622 can enter the filtrate cylinder 71 from the filter cylinder 6 under the push of the pushing cylinder 623. The pushed out conical filter plugs 622 are moved into the filtrate cylinder 71 along the vertical end of the inverted L-shaped guide rod 621 in turn (the angle of the inverted L-shaped guide rod 621 is greater than 90 degrees, which facilitates the conical filter plug 622 to move from the horizontal end to the vertical end of the inverted L-shaped guide rod 621), so that the spray water entering the filtrate cylinder 71 can be filtered by the conical filter plug 622, which is beneficial to the recycling of the spray water.

[0035] The large diameter end of the conical filter plug 622 is located near the end of the pushing cylinder 623, and the small diameter ends of the two adjacent conical filter plugs 622 are in conflict with the large diameter ends. The conical filter plug 622 is coaxially movably sleeved on the outside of the horizontal end of the inverted L-shaped guide rod 621, and the outer peripheral wall of the large diameter end of the conical filter plug 622 is in contact with the inner wall of the filter cylinder 6. The conical filter plug 622 is a filter mesh structure; when the conical filter plug 622 moves in the filter cylinder 6, it is beneficial to scrape off the particles adhering to the inner wall of the filter cylinder 6, thereby reducing the adhesion of particles on the inner wall of the filter cylinder 6.

[0036] Example 4 Based on the first embodiment, Figure 1 、 Figures 7 and 8As shown, a push cylinder 6231 is coaxially provided on the piston rod of the pushing cylinder 623. The push cylinder 6231 pushes the cylinder 623 away from the pushing cylinder 623 end, which is a circular ring-shaped structure, and the outer diameter of the push cylinder 6231 is smaller than the inner diameter of the filter cylinder 6. The push cylinder 6231 is coaxial with the horizontal end of the inverted L-shaped guide rod 621; it is convenient for the conical filter plug 622 to enter the filtrate cylinder 71 from the filter cylinder 6 under the push of the pushing cylinder 623 (the push cylinder 6231 can move outside the horizontal end of the inverted L-shaped guide rod 621, thereby pushing the conical filter plug 622 to move), and then the conical filter plug 622 located in the filter cylinder 6 can be pushed out and moved along the inverted L-shaped guide rod 621 into the filtrate cylinder 71, and then the conical filter plug 622 after filtering the dust in the filter cylinder 6 can be moved into the filtrate cylinder 71, so that the particulate dust in the spray water can be filtered.

[0037] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
