In order to facilitate the storage of high-pressure gas needed in sandblasting, a pressure tank for storing high-pressure gas is very necessary.
[0003] The conventional pressure tank has the following disadvantages: 1. The pressure tank does not have a pressure buffer structure, and the tank body is easily damaged when subjected to a large pressure. Therefore, we propose a pressure tank for sandblasting. Utility Model Content

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A pressure tank for sandblasting, comprising a bottom plate, supporting legs, an outer tank body, an inner tank body, an inflation pipe, a second air outlet pipe and an air pressure detector, wherein the inner tank body is fixed to the inner bottom of the outer tank body by a supporting rod, one end of the inner tank body is connected to the second air outlet pipe near the bottom, one end of the second air outlet pipe extends out of the outer tank body, one end of the inner tank body is provided with a first air outlet pipe near the top, the first air outlet pipe is located in the outer tank body, and a pressure relief valve is provided on the first air outlet pipe; an inflation pipe is provided at one end of the top of the inner tank body, the top of the inflation pipe passes through one end of the top of the outer tank body, and an air outlet gap is provided at the edge of the outer tank body.
[0007] Furthermore, the inflation pipe and the second air outlet pipe are respectively provided with an inflation valve and a shut-off valve. The inflation valve facilitates the filling of external air into the inner tank body through the inflation pipe, and the shut-off valve facilitates the control of the opening and closing of the second air outlet pipe.
[0008] Furthermore, an air pressure detector is installed at one end of the outer tank body away from the second air outlet pipe through a reserved hole, and a detection end of the air pressure detector is located inside the outer tank body.

[0010] Furthermore, protective convex edges are provided near the edges at both ends of the outer tank body, and the protective convex edges can provide a certain degree of protection for the stop valves and air pressure detectors at both ends of the outer tank body.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The utility model relates to a pressure tank for sandblasting. When the pressure in an inner tank body is too high and reaches the set value of a pressure relief valve, the pressure relief valve releases the excess gas in the inner tank body into the buffer space between the outer tank body and the inner tank body, and slowly releases the gas in the outer tank body into the surrounding space through the air outlet gap at the edge of the outer tank body. The pressure tank has a pressure buffer structure. When the outer tank body is subjected to a large pressure, the excess gas can be effectively buffered under the premise of ensuring safety, and the damage of the inner tank body can be effectively prevented.
