Description

Technical Field

[0001] This utility model relates to the technical field of liquid mixing devices, specifically a multi-liquid pneumatic mixing device for chemical applications. Background Technology

[0002] Chemical liquids are a general term for various liquid substances involved in the chemical industry. They are widely used in chemical production, pharmaceutical manufacturing, energy development, materials processing and many other fields. There are many types of chemical liquids, and mixing multiple chemical liquids can change their physical state or properties to meet the needs of subsequent processing or use.

[0003] Chinese Patent Publication No. CN 206535473 U discloses a vertical chemical liquid mixing agitator, including a tank body, an agitator, and a stirring motor. The tank body is provided with a rotating shaft through hole, a feed inlet, a vent, and a discharge outlet. The rotating shaft through hole is located at the top center of the tank body. The feed inlet and vent are located at the top of the tank body and outside the rotating shaft through hole. The discharge outlet is located at the lower part of the side wall of the tank body. The agitator includes a rod body, a spiral blade, a mixing short rod, and a bottom blade. The spiral blade and the mixing short rod are located on the side wall of the rod body, with the spiral blade located at the upper part of the mixing short rod. The bottom blade is located at the bottom end of the rod body. The upper part of the rod body passes through the rotating shaft through hole, and the top end of the rod body is connected to the stirring motor.

[0004] The aforementioned agitator uses spiral blades, mixing rods, and blades to mix the liquid in the tank; however, the agitator uses a single mechanical agitation method, which, although it can achieve a mixing effect, has relatively low agitation efficiency, requires a long time to completely mix multiple liquids, and has a small tank capacity, so it can mix a small amount of liquid at a time. Utility Model Content

[0005] The purpose of this invention is to provide a multi-liquid pneumatic mixing device for chemical applications. It utilizes negative pressure to transfer liquids into a mixing tank. While the mixing rack in the tank agitates the liquid, air generated by an air pump aerates the liquid. By employing two mixing methods simultaneously, the liquids are mixed efficiently. Furthermore, a return pipe allows the liquids to circulate between the mixing tank and the storage tank, enabling the mixing of a larger quantity of liquids at a time, thus solving the technical problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A chemical multi-liquid pneumatic mixing device, comprising

[0008] A mixing assembly for mixing chemical liquids, with a storage assembly on one side;

[0009] The three-way valve, located above the material storage assembly, has three ports that are fixedly connected to the air supply pipe, the feed pipe, and the suction pipe, respectively.

[0010] The end of the gas delivery pipe furthest from the tee is fixedly connected to the output end of the air pump; a return pipe is also provided on one side of the tee.

[0011] The mixing assembly includes a mixing tank with a mixing rack in the middle of the tank; a feed inlet is located in the middle of the bottom of the mixing tank, and a return outlet is located on one side of the upper end of the mixing tank.

[0012] The storage assembly includes a storage hopper, the top of which is connected to a top cover; the top cover has a sealing opening in the middle and a circulation opening on one side of the top.

[0013] The feeding pipe is fixedly connected to the inlet at one end away from the tee; the suction pipe is located inside the storage tank at one end away from the tee; one end of the return pipe is fixedly connected to the circulation port, and the other end of the return pipe is fixedly connected to the return port.

[0014] As a further technical solution of this utility model, the top of the mixing tank is fixedly connected to the sealing cover; the bottom of the mixing tank is provided with a discharge port, which is located on the side of the inlet, and the discharge port is fixedly connected to the end of the transfer pipe equipped with a valve, and the other end of the transfer pipe is fixedly connected to the liquid storage device.

[0015] As a further technical solution of this utility model, the middle of the stirring rack is fixedly connected to the lower end of the rotating shaft, and the top of the rotating shaft is fixedly connected to the output shaft of the motor.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. In this utility model, the compressed gas generated by the air pump flows rapidly in the air delivery pipe, tee, and feeding pipe, while simultaneously generating negative pressure in the suction pipe. Under the action of negative pressure, the liquid in the storage tank enters the feeding pipe through the suction pipe and, together with the air, enters the mixing tank through the feeding pipe. After entering the mixing tank, the air diffuses rapidly, forming aeration in the liquid. Aeration can agitate the liquid. In conjunction with the stirring frame in the mixing tank, the liquid can be mixed in two ways, improving the mixing efficiency of the liquid.

[0018] 2. In this utility model, when the liquid level in the mixing tank rises to the return port, the liquid in the mixing tank can flow back into the storage tank through the return pipe, thereby forming a circulation of the liquid. This allows the liquid to be mixed multiple times during the circulation process, further improving the mixing efficiency. In addition, the liquid in the mixing tank and the storage tank can be circulated and mixed, increasing the amount of liquid that can be mixed at one time. Attached Figure Description

[0036] The feeding pipe 7 is fixedly connected to the feed inlet 19 at one end away from the tee 5; the suction pipe 8 is located inside the storage tank 21 at one end away from the tee 5; one end of the return pipe 9 is fixedly connected to the circulation port 24, and the other end of the return pipe 9 is fixedly connected to the return port 110.

[0037] The upper outer side of the mixing tank 11 is uniformly and fixedly connected with multiple connecting seats 13, which are arranged in a ring, and the bottom of each of the multiple connecting seats 13 is fixedly connected with a support leg 14.

[0038] The top of the mixing tank 11 is fixedly connected to the sealing cover 12; the bottom of the mixing tank 11 is provided with a discharge port 15, which is located on the side of the inlet 19, and the discharge port 15 is fixedly connected to the end of the transfer pipe equipped with a valve, and the other end of the transfer pipe is fixedly connected to the liquid storage device.

[0039] By adopting the above technical solution, the compressed gas generated by the air pump 3 flows rapidly in the air delivery pipe 6, the three-way valve 5 and the feeding pipe 7, while generating negative pressure in the suction pipe 8. Under the action of negative pressure, the liquid in the storage tank 21 enters the feeding pipe 7 through the suction pipe 8 and enters the mixing tank 11 together with the air through the feeding pipe 7. After entering the mixing tank 11, the air diffuses rapidly and forms aeration in the liquid. Aeration can agitate the liquid. In conjunction with the stirring frame 112 in the mixing tank 11, the liquid can be mixed in two ways, improving the mixing efficiency of the liquid.

[0040] In this embodiment, the middle of the stirring rack 112 is fixedly connected to the lower end of the rotating shaft 111, and the top of the rotating shaft 111 is fixedly connected to the output shaft of the motor 17; the upper end of the rotating shaft 111 is located inside the cylinder seat 16 and is rotatably connected to the cylinder seat 16 through multiple bearings 18; the bottom of the cylinder seat 16 is fixedly connected to the top of the sealing cover 12, and the sealing cover 12 has a through hole in the middle for the rotating shaft 111 to pass through;

[0041] The storage tank 21 and the top cover 22 are each provided with multiple filling ports 25; multiple support seats 26 are evenly fixedly connected to the lower outer side of the storage tank 21; the bottom of the multiple support seats 26 is fixedly connected to the top end of the base frame 4; the bottom end of the air supply pipe 6 near the tee 5 and both ends of the feeding pipe 7 of the base frame 4 away from the storage tank 2 are fixedly connected to support frames 10, wherein the bottom of the support frame 10 on the air supply pipe 6 and the support frame 10 near the tee 5 of the feeding pipe 7 are fixedly connected to the top of the top cover 22, and the support frame 10 at the end of the feeding pipe 7 away from the tee 5 is fixedly connected to the mixing tank 11.

[0042] By adopting the above technical solution, when the liquid level in the mixing tank 11 rises to the return port 110, the liquid in the mixing tank 11 can flow back into the storage tank 21 through the return pipe 9, thereby allowing the liquid to circulate and be mixed multiple times during the circulation process, further improving the mixing efficiency; in addition, the liquid in the mixing tank 11 and the storage tank 21 can be circulated and mixed, thereby increasing the amount of liquid that can be mixed at one time.

[0043] The working principle of this utility model is as follows: the compressed gas generated by the air pump 3 flows rapidly in the air delivery pipe 6, the three-way valve 5 and the feeding pipe 7, and at the same time, a negative pressure is generated in the suction pipe 8. Under the action of the negative pressure, the liquid in the storage tank 21 enters the feeding pipe 7 through the suction pipe 8 and enters the mixing tank 11 together with the air through the feeding pipe 7. After the air enters the mixing tank 11, it diffuses rapidly and forms aeration in the liquid. The aeration can stir the liquid. With the help of the stirring frame 112 in the mixing tank 11, the liquid can be mixed in two ways, which improves the mixing efficiency of the liquid.

[0044] When the liquid level in the mixing tank 11 rises to the return port 110, the liquid in the mixing tank 11 can flow back into the storage tank 21 through the return pipe 9, thereby forming a circulation of the liquid. This allows the liquid to be mixed multiple times during the circulation process, further improving the mixing efficiency. In addition, the liquid in the mixing tank 11 and the storage tank 21 can be circulated and mixed, increasing the amount of liquid that can be mixed at one time.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
