[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0025] Please see the attached Figures 1-6 The utility model discloses a gypsum slurry spray gun for uniform wall spraying, comprising a spray gun body 1, wherein the spray gun body 1 comprises a feed portion 11 and a spray gun 12, and further comprises a nozzle assembly 2 and a particle filter assembly 3, wherein:

[0026] The feed part 11 and the spray gun 12 are respectively installed with a material pipe 13 and a pump pipe 14, and a filter pipe 15 is installed between the material pipe 13 and the pump pipe 14;

[0027] The spray head assembly 2 includes a nozzle 24 detachably mounted on the front end of the spray gun 12;

[0028] The particle filter assembly 3 includes a split ring 324 detachably mounted above the filter tube 15 , and a plurality of filter screens 323 are mounted in the split ring 324 .

[0029] Please refer to the attached Figure 5 、 Figure 6 The upper end of the filter tube 15 is provided with a splitting opening, the splitting ring 324 is movably connected and fits with the splitting opening, the inner wall of the splitting ring 324 is also installed with a collecting ring 37, the filter screen 323 is fixed in the collecting ring 37, and an installation box 31 is also installed between the material pipe 13 and the pump pipe 14. The upper end of the installation box 31 is detachably installed with a box cover 32, the split tube is fixed to the lower end of the box cover 32, and the installation box 31 wraps the filter tube 15 inside.

[0030] In this embodiment, the detachable box cover 32 can drive the split tube to be removed from the filter tube 15, so as to facilitate the cleaning of the filter screen 323 and the inside of the filter tube 15 to avoid clogging. At the same time, the box cover 32 can prevent the gypsum slurry from being collected when the water in the gypsum slurry seeps out of the filter tube 15, thereby preventing the water from being scattered and causing pollution during the spraying operation.

[0031] Please refer to the attached Figure 5 、 Figure 6 A fixing plate 35 is symmetrically installed in the installation box 31. The fixing plate 35 is provided with a fixing screw hole 34. The box cover 32 is provided with a penetrating locking hole 321. The locking hole 321 is movably connected with a fixing bolt 33. The fixing bolt 33 is threadedly connected to the fixing screw hole 34. A sealing strip 322 is installed at the lower end of the box cover 32. A connecting plate 36 is installed on the inner wall of the installation box 31. The connecting plate 36 is provided with a sealing groove 361. The sealing strip 322 is movably connected and matched with the sealing groove 361.

[0032] In this embodiment, the box cover 32 is installed and fixed by means of fixing bolts 33, and the impurities filtered out by the filter 323 can be retained and collected in the collection bin through the collecting ring 37. When the split tube is taken out, the collecting ring 37 is taken out together, which facilitates the cleaning of the filtered impurities. Example 2

[0033] Based on the above embodiment 1, please refer to the attached Figure 3 、 Figure 4 The nozzle 24 is long and flat, with a compression ring 23 installed on one side of the nozzle 24, an operating ring 22 installed on the side end of the compression ring 23, and a connecting pipe 21 with an external thread on the outer wall installed on the side end of the operating ring 22. The front end of the spray gun 12 is provided with a mounting screw hole, and the connecting pipe 21 is threadedly connected to the mounting screw hole. The inner wall of the compression ring 23 is an arc-shaped bend toward the nozzle 24;

[0034] In this embodiment, the nozzle 24 is detachably mounted on the spray gun 12 through the connecting tube 21, which facilitates the disassembly and cleaning of the nozzle 24. The compression ring 23 can compress the gypsum slurry in the connecting tube 21 when it enters the nozzle 24, thereby increasing the pressure of the gypsum slurry during spraying and achieving a better surface-forming effect during spraying of the gypsum slurry.

[0035] The working principle and usage process of the present invention are as follows: the mixed gypsum slurry enters the filter tube 15 from the material pipe 13, and the pump tube 14 pumps high-pressure gas into the spray gun 12 for pressurization. When the gypsum slurry passes through the filter screen 323, the filter screen 323 filters the gypsum slurry, and the large particles of impurities in the gypsum slurry are blocked by the filter screen 323 at the side end of the filter screen 323 and are located in the collecting circle 37. The filtered gypsum slurry enters the spray gun 12, and then passes through the connecting pipe 21 and the compression ring 23 and is sprayed out from the nozzle 24. When the gypsum slurry passes through the compression ring 23, the passage through which the gypsum slurry passes becomes narrower, and the pressure on the gypsum slurry is further increased. Finally, the gypsum slurry is sprayed out from the nozzle 24 in a surface shape under the action of the high-pressure gas in the pump tube 14 and is applied to the wall surface.

[0036] After spraying is completed, the fixing bolts 33 are unscrewed, and then the box cover 32 is lifted upward. The box cover 32 drives the splitting ring 324 and the collecting ring 37 to move upward and be taken out of the installation box 31. During this process, the collecting ring 37 is removed from the installation box 31 along with the filtered large particles of impurities. At this time, the debris in the filter screen 323 and the collecting ring 37 can be cleaned, and the filter tube 15 can be cleaned at the same time.
