Description

Technical Field

[0001] This utility model relates to the field of stirring technology, specifically to a stirring device for preparing barium sulfate slurry. Background Technology

[0002] In the double-disc casting machine of a smelter, the barium sulfate mixing tank serves to prepare barium sulfate slurry for spraying onto the casting mold, preventing molten copper from sticking to the mold and facilitating demolding. It also protects the mold and improves the physical specifications of the anode plates. However, the barium sulfate slurry is generally prepared using powdered barium sulfate. Existing mixing tanks use stirring blades for agitation, and there is a certain gap between the blades and the tank body. Furthermore, barium sulfate is dense and insoluble in water, which easily leads to the barium sulfate slurry adhering to the sides of the tank and failing to be thoroughly stirred, affecting the stirring effect. Therefore, uneven stirring results in unstable barium sulfate slurry concentration, affecting the spraying quality and ultimately the quality of the copper plates cast from the discs. Over long-term operation, the barium sulfate material inside the tank gradually adheres to the inner wall, causing severe adhesion around the tank's perimeter. To avoid impacting subsequent production processes, the tank needs to be opened periodically for cleaning, which not only increases maintenance costs but also reduces production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a stirring device for preparing barium sulfate slurry that improves stirring efficiency, reduces deposition and adhesion, and is easy to operate. This solves the technical problem that existing devices have gaps between the stirring blades and the tank, resulting in uneven stirring, easy adhesion and deposition around the tank, affecting the stirring effect and reducing production efficiency.

[0004] To solve the above technical problems, the solution adopted by this utility model is as follows:

[0005] A stirring device for preparing barium sulfate slurry includes a stirring tank, a vent pipe, support rods, and an air jet pipe. The stirring tank is equipped with a matching tank cover. The upper end of the vent pipe is connected to the tank cover, and the lower end is connected to the air jet pipe. Four support rods are provided, which are symmetrically fixed in pairs to the middle of the inner wall of the stirring tank. The air jet pipe is annular and welded to the support rods. Several air outlets are provided on the air jet pipe, which are evenly distributed at an angle, and the air outlets of two adjacent air outlets have opposite directions. The vent pipe is connected to an air compressor via an external pipe. The air compressor compresses air into a gas with a certain pressure. After the gas is compressed into compressed air, it is delivered to the vent pipe through the external pipe, and then to the jet pipe supported by a support rod. The jet pipe is located below the liquid surface in the mixing tank. The compressed air is ejected through the outlet pipe installed at an angle on the jet pipe. The two adjacent outlet pipes are tilted in opposite directions, which can make the compressed air form a vortex in the mixing tank, enhancing the mixing effect. By spraying compressed air for mixing, the deposition of barium sulfate powder at the bottom of the mixing tank can be reduced, avoiding uneven mixing caused by deposition. At the same time, it can reduce the adhesion of barium sulfate raw material to the tank wall, reducing the difficulty of subsequent cleaning work.

[0006] Furthermore, the tank cover is equipped with a connecting pipe; the connecting pipe is cross-shaped, with its middle part rotatably connected to the tank cover and its lower end threadedly connected to the vent pipe. The vent pipe is connected to the tank cover via the connecting pipe, facilitating the transfer of compressed air from the tank cover to the vent pipe, and then distributing it inside the mixing tank. This facilitates the installation and maintenance of the vent pipe, and also allows for easy removal of the vent pipe from the tank cover, thus facilitating the opening and closing of the tank cover for the addition of barium sulfate.

[0007] Furthermore, the jet pipe includes jet pipe A and jet pipe B; the diameter of jet pipe A is larger than the diameter of jet pipe B; jet pipe A and jet pipe B are fixedly installed on the support rod from the outside to the inside. Jet pipe A and jet pipe B are two concentric rings. Through the design of the double-layer jet pipe, the entire area of ​​the mixing tank can be covered more effectively, reducing dead zones in the mixing, enhancing the mixing effect, improving the mixing efficiency, and making the slurry mix more uniformly.

[0008] Furthermore, the vent pipe is in a "V" shape, with its lower end connected to jet pipe A and jet pipe B respectively. The V-shaped vent pipe can evenly distribute the gas into the two different jet pipes A and B, facilitating the even distribution of compressed air in the two jet pipes within the mixing tank, and then evenly spraying it into the mixing tank, thereby enhancing the uniformity of gas distribution within the mixing tank and improving mixing efficiency.

[0009] The working principle of this utility model is as follows:

[0010] Open the tank lid, add barium sulfate powder and the corresponding proportion of water to the mixing tank, then close the lid. Rotate the connecting pipe to connect the connecting pipe and the vent pipe. The pipe connected to the connecting pipe is connected to an air compressor. The air compressor delivers compressed air to the connecting pipe through the external pipe, and then to the vent pipe. The compressed air is then evenly distributed into jet pipes A and B, and sprayed out through the air outlets on jet pipes A and B. The two adjacent air outlets are inclined in opposite directions. The compressed air creates a vortex in the mixing tank, enhancing the mixing effect and reducing the deposition of barium sulfate powder at the bottom of the mixing tank, thus avoiding uneven mixing caused by deposition. At the same time, the double-layer jet pipe design can more effectively cover the entire area of ​​the mixing tank, reducing dead zones and reducing the adhesion of barium sulfate raw materials to the tank wall, thus reducing the difficulty of subsequent cleaning work.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model delivers compressed air to the jet pipe through the vent pipe, and then sprays it out through the outlet pipe, so that the compressed air forms a vortex in the mixing tank, which effectively improves the mixing uniformity of barium sulfate slurry, reduces powder deposition and tank wall adhesion, reduces cleaning difficulty, and improves production efficiency.

[0013] 2. This utility model, through the design of the "human" shaped vent pipe and the double-layer jet pipe, can evenly distribute compressed air into the mixing tank, effectively cover the entire mixing area, reduce dead corners, make the barium sulfate slurry mix more evenly, and improve the mixing efficiency.

[0020] The following is a detailed description of a stirring device for preparing barium sulfate slurry according to the present invention, with reference to the accompanying drawings: Example 1

[0021] A stirring device for preparing barium sulfate slurry includes a stirring tank 1, a vent pipe 2, a support rod 3, and a jet pipe 4. The stirring tank 1 is provided with a matching tank cover 5. The upper end of the vent pipe 2 is connected to the tank cover 5, and the lower end is connected to the jet pipe 4. There are four support rods 3, which are symmetrically fixed in pairs to the middle of the inner wall of the stirring tank 1. The jet pipe 4 is annular and welded to the support rod 3. The jet pipe 4 is provided with a plurality of air outlet pipes 7, which are evenly distributed obliquely on the jet pipe 4, and the air outlets of two adjacent air outlet pipes 7 are in opposite directions.

[0022] The working principle of this embodiment is as follows:

[0023] Open the tank lid, add barium sulfate powder and water in the corresponding proportion to the mixing tank 1, and then close the tank lid 5. The vent pipe 2 is connected to the air compressor through an external pipe. The air compressor delivers compressed air to the vent pipe 2 through the external pipe, and then sprays it out through the air outlet pipe 7 on the jet pipe 4. The two adjacent air outlet pipes 7 are tilted in opposite directions. The compressed air sprayed out forms a vortex in the mixing tank 2 to stir the mixture, which enhances the stirring effect. This can reduce the deposition of barium sulfate powder at the bottom of the mixing tank and avoid uneven stirring caused by deposition. It can also reduce the adhesion of barium sulfate raw material to the tank wall and reduce the difficulty of subsequent cleaning work. Example 2

[0024] The difference from Embodiment 1 is that the can lid 5 is provided with a connecting pipe 6; the connecting pipe 6 is in the shape of a cross, and its middle part is rotatably connected to the can lid 5, and its lower end is threadedly connected to the vent pipe 2; the jet pipe 4 includes a jet pipe A41 and a jet pipe B42; the diameter of the jet pipe A41 is larger than the diameter of the jet pipe B42; the jet pipe A41 and the jet pipe B42 are fixedly installed on the support rod 3 from the outside to the inside; the vent pipe 2 is in the shape of a V, and its lower end is connected to the jet pipe A41 and the jet pipe B42 respectively.

[0025] The vent pipe 2 is connected to the tank cover 5 via the connecting pipe 6, facilitating the transfer of compressed air from the tank cover 5 to the vent pipe 2, and then distributing it inside the mixing tank 1. This design makes the vent pipe 2 easy to install and maintain, and also allows for easy removal of the vent pipe 2 from the tank cover 5, facilitating the opening and closing of the tank cover 5 for the addition of barium sulfate. The herringbone-shaped vent pipe 2 can evenly distribute the gas into two different jet pipes A41 and B42, which are two concentric rings. The double-layered jet pipe design can more effectively cover the entire area of ​​the mixing tank 1, enhancing the uniformity of gas distribution within the mixing tank 1, reducing dead zones, enhancing the mixing effect, improving mixing efficiency, and resulting in more uniform slurry mixing.

[0026] The working principle of this embodiment is the same as that of Embodiment 1.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
