The invention discloses a novel environmental protection water mist sand gun, which comprises a gun head, a water mist gun and a sand gun, the gun head is connected with the water mist gun, one end of the gun head is connected with the sand tube connected; the water mist gun is provided with a water mist holster, a water inlet pipe and a water mist control head, and the water mist control head is provided with a first water mist control head and a second water mist control head, two water mist control heads The control head is located at the root of the sand gun, the water mist gun is mounted on the outside of the sand gun, and the gun head is connected with the end of the sand gun.

As a further description of the above-mentioned new type of environmentally friendly water mist sand gun, the sand gun is provided with threads at the root and end respectively, and is set inside the water mist holster, and the root of the sand gun passes through the water mist holster Stretch out to the front end of the second water mist control head, when the water mist gun sprays water, the water mist layer wraps the iron sand sprayed by the sand gun.

As a further description of the above-mentioned new type of environmentally friendly water mist sand gun, it also includes a fixed ring, the inner and outer surfaces of the fixed ring are provided with threads and are sleeved on the end of the sand gun, and the end of the sand gun passes through the fixed ring and the gun head. After being combined, it is connected to the sand pipe, and a water inlet is provided on the side of the water mist holster, and the water inlet is connected to the water inlet pipe.

The beneficial effects of the present invention are: the invention 1, reducing dust pollution. 2. Lightweight design, small and light structure, easy to carry. 3. It is simple to make, easy to assemble, easy to use, and very practical. Through technological innovation, it adopts a spray type, sand is sprayed from the sand gun in the water gun, and water is sprayed from the water mist spray gun to form a mist that surrounds the iron sand from all sides, which does not affect sandblasting, but also has a dust reduction effect. By using the invention, the sand blasting environment can be improved, the bad situation of dust flying all over the sky during sand blasting can be changed in the past, the sand blasting environment can be further improved, and there is basically no dust, which is of great significance to environmental protection.

Detailed ways

The following will clearly and completely describe the technical solutions in the design embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Fig. 1-4, a kind of water mist sand gun of invention, it comprises:

The invention discloses an inventive water mist sand gun, which includes a gun head 1, a sand gun 2, a water mist gun 3, a water mist gun cover 4, a water inlet pipe 5, a first water mist control head 6, and a second water mist control head. Head 7 and composed.

The designed gun head is a kind of internally threaded pipe with a limit hole 11 on the pipe wall. After connecting the sand tube and the sand gun, the screw 12 is tightened through the limit hole to lock the sand tube and the sand gun. The head structure is shown in Figure 1.

The designed sand gun 2 is a threaded tubular nozzle, the specifications and materials are similar to those of ordinary sand guns, made of stainless steel pipes, with threads at both ends, and one end of the large screw thread 21 is connected to the sand pipe and the water mist holster 4, and the small One end of the head thread 22 is connected to the second water mist control head 7, and the structure is shown in FIG. 2 .

The designed water inlet pipe 5 is connected to the side of the water mist gun. One end of the elbow 51 has a threaded nut 52 connected to the water mist gun sleeve, and the other end is a stepped non-slip design. The water pipe is connected with a locking ring to lock the water pipe And the water inlet pipe, the structure is shown in Figure 3.

The designed water mist holster 4 is a machined pipe, one end is large and the other end is small, the big end has an internal thread to connect the first water mist control head 6, and the small end has an internal thread to connect to the sand gun 2. Wrap the sand gun, see Figure 4 for details.

The gun head of the present invention is connected to the sand pipe and the sand gun, the water mist gun holster is set on the sand gun, the water inlet pipe is connected to the side of the water mist gun holster, the first water mist control head is connected to the water mist gun holster, and finally the second The second water mist control head is connected to the sand outlet end of the sand pipe, and the water mist sand gun is assembled. It also includes a fixing ring 8, the inner and outer surfaces of the fixing ring are provided with threads 81 and are sleeved on the end of the sand gun, and the end of the sand gun is connected to the sand pipe after being combined with the gun head 1 through the fixing ring. A water inlet is provided on the side of the water inlet, and the water inlet is connected to the water inlet pipe. In addition, the water pipe and sand pipe are separated separately, which can spray water and sand at the same time, or sandblasting or water spraying alone, and the water pipe can be removed directly when water spraying is not needed, which is easy to operate and does not affect sandblasting. The water mist sprayed by the water mist spray gun forms a water mist protective layer to surround the sprayed iron sand, and the iron sand is tightly wrapped in the water mist layer. The iron sand forms a water flow along with the water mist and flows away without generating dust pollution, greatly improving Improve the sanding environment. Turn on the water pipe switch, the water flows through the water inlet pipe, the water mist gun holster, the first water mist control head and sprays to the second water mist control head, and the high-speed water flow passes through the round hole in the first water mist control head to pressurize, and the high pressure Water forms a high-pressure spray in the gap between the first and second water mist control heads, and sprays out along the slope of the second water mist control head to form a funnel-shaped water mist protective layer, and then turn on the switch of the sand gun. The iron sand impacts the steel plate, and the dust formed by the impact on the steel plate is soaked by the water mist layer, and flows away with the water flow, without polluting the outside air.
