[0029] like Figure 1 , Figure 2As shown, the present invention provides a circulating spray mixing device, including a tank body 1 and a tank cover 2. A spray pipe is installed inside the tank body 1, and a material pipe 4 is vertically arranged above the spray pipe. Multiple automatic rotating spray heads 6 are distributed at intervals on the upper surface of the spray pipe.

It also includes an annular coil 3, the inner side of which is connected to the outer end of each connecting pipe 5.
[0030] The top of the material pipe 4 extends upward through the tank cover 2 and is equipped with an inlet valve 7. The outlet of the inlet valve 7 is connected to the inlet of the material pipe 4. A discharge valve 8 is installed at the bottom of the tank body 1. The inlet of the discharge valve 8 is connected to the inside of the tank body 1.
[0031] An external pipeline is also connected between the first outlet of the discharge valve 8 and the first inlet of the feed valve 7. The external pipeline includes a discharge pipe 9 connected to the first outlet of the discharge valve 8 and a feed pipe 10 connected to the first inlet of the feed valve 7. The discharge pipe (9) and the feed pipe 10 are connected by a pneumatic pump 11.
[0032] The circulating spray mixing device provided by this utility model uses a pneumatic pump to draw liquid from the tank with compressed air and then re-inject it into the tank. A non-powered automatic rotating spray head generates a vortex as the liquid is injected into the tank, resulting in more uniform mixing. A three-way inlet and outlet valve allows for the injection of new material into the tank or the discharge of the already mixed material, achieving material dispersion and uniform mixing, replacing traditional stirring and mixing methods, and reducing equipment costs. Furthermore, the use of a pneumatic pump and a non-powered automatic rotating spray head eliminates the risks associated with direct on-site use of electricity in hazardous areas.
[0033] like Figure 3 , Figure 4 As shown, the automatic rotating spray head 6 includes a connecting section 601 that is detachably connected to the connecting pipe 5 or the annular coil 3. A spray pipe 602 communicating with the connecting pipe 5 or the annular coil 3 is provided in the connecting section 601. A rotating bushing 603 is rotatably mounted at the bottom end of the spray pipe 602. At least one rotating blade 604 is installed at intervals on the outer surface of the rotating bushing 603. The outer side of the rotating blade 604 is spirally distributed along the rotating bushing 603.
[0034] like Figure 1 , Figure 2 As shown, the feed valve 7 is also provided with a second inlet for feeding raw materials into the tank 1; the discharge valve 8 is also provided with a second outlet for discharging the mixed material out of the tank 1.
[0035] In this embodiment, the pneumatic pump 11 is a pneumatic diaphragm pump.
[0036] like Figure 1 As shown, the annular coil 3 is fixed by a bracket 12 installed on the inner wall of the tank 1.
[0037] like Figure 1 As shown, the tank body 1 and the tank cover 2 are detachably connected by bolts.
[0038] In this embodiment, the automatic rotating spray head 6 is model PG123.
[0039] In this embodiment, the feed valve 7 is a DN65 three-way ball valve.
[0040] In this embodiment, the discharge valve 8 is a DN65 three-way ball valve.
[0041] In this embodiment, the inner diameter of the material pipe 4 is 65 mm, and the inner diameter of the annular coil 3 is 25 mm.
[0042] The implementation method of this utility model includes the following steps:
[0043] 1) The material to be mixed is fed into the tank 1 through the second inlet of the tank cover 2 or the feed valve 7;
[0044] 2) A pneumatic diaphragm pump is used to draw material from the tank 1 through the first outlet of the discharge valve 8 and inject it into the material pipe 4 through the first inlet of the inlet valve 7;
[0045] 3) The liquid enters in batches through the material pipe 4 into each connecting pipe 5 and the annular coil 3;
[0046] 4) When the liquid passes through the automatic rotating spray head 6, it hits the bottom of the rotating paddle 604 after passing through the spray pipe 602. Since the rotating paddle 604 is spirally arranged, under the flushing of the water flow, the rotating paddle 604 drives the rotating bushing 603 to rotate, so that the water flow is injected into the tank 1 from a 360° direction, generating a vortex of a certain size, which accelerates the mixing of the material in the tank 1.
[0047] 5) After the liquid in tank 1 is evenly mixed, the evenly mixed material can be discharged through the second outlet of discharge valve 8.
[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
