Description

Technical Field

[0001] The utility model relates to the technical field of stirring, in particular to a mixing and stirring tank. Background Art

[0002] In industrial production, the mixing and stirring tank is one of the most commonly used devices. The mixing tank is used for stirring and mixing various materials. Most of the existing mixing and stirring tanks adopt the feeding method of upper feeding and lower discharging, so that the materials at the bottom are difficult to be stirred, the stirring time is long, and the stirring effect is not good. In addition, the mixing and stirring tank also has different feeding methods, such as direct pouring, screw feeding and siphon feeding. For the mixing tank with siphon feeding, multiple feeding nozzles are usually set. During the siphon feeding process, there will be a counterflush of different materials, resulting in the problem that the feeding of the material pipe with a small pressure is difficult or even impossible to feed. In view of this, the utility model provides a mixing and stirring tank in order to solve the above technical problems. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a mixing and stirring tank to improve the stirring effect and prevent the counterflush of various materials during siphon, thus affecting the difficult siphon feeding.

[0004] To solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A mixing and stirring tank includes a tank body. An upper top plate is arranged above the tank body. A discharge port is arranged at the upper end of the tank body. A lower bottom plate is arranged below the tank body. A lower inner cylinder is arranged between the lower bottom plate and the inner bottom surface of the tank body. A plurality of feeding pipes are arranged on the outer periphery of the lower inner cylinder. The feeding pipes penetrate to the outside of the tank body. A through hole is arranged at the center of the lower bottom plate. The through hole is located inside the lower inner cylinder. A baffle is also arranged in the lower inner cylinder. The ports of the feeding pipes are located on different sides of the baffle. A plurality of baffle plates are arranged on the inner wall of the tank body. The baffle plates are vertically arranged on the inner wall of the tank body between the upper top plate and the lower bottom plate.

[0006] Further, a motor is arranged at the top of the tank body. The output end of the motor is connected with a rotating shaft. The rotating shaft extends into the tank body and stirring blades are arranged on the rotating shaft. The stirring blades are located above the lower bottom plate.

[0007] Further, the number of the feeding pipes is 3. Flanges are arranged on the outer ports of the feeding pipes.

[0008] Further, a plurality of reinforcing rings are arranged on the outer wall of the tank body. Supporting ears are arranged above the tank body.

[0009] Further, a plurality of rib plates are arranged between the edge of the upper top plate and the inner wall of the tank body. An upper inner cylinder is arranged at the center of the upper top plate.

[0010] Further, a lower stirring piece is also arranged at the bottom end of the rotating shaft. The lower stirring piece is close to the through hole.

[0011] Furthermore, the gap between the lower stirring blade and the through hole is less than 2 cm.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, the discharge port is arranged above the tank body, the feed pipe is arranged below the tank body and multiple feed pipes are provided. Multiple materials can be fed simultaneously, and the materials are fed from the bottom, so that the materials can contact the stirring blades immediately to generate siphon, making it easier for the materials to flow in. As the materials gradually increase and rise in the tank body, the materials at each level can gradually contact the stirring blades and be mixed. In addition, baffle plates are arranged on the inner wall of the tank body. By this technical means, the stirring effect can be improved and the stirring time can be shortened. An inner cylinder is arranged at the bottom of the tank body, and baffle plates are arranged in the inner cylinder. The baffle plates can isolate the direct impact when different materials are fed, thus solving the problem that it is difficult or even impossible to feed the material pipe with a small pressure. A reinforcing ring is arranged on the outer side of the tank body, and rib plates are arranged on the upper top plate to increase the strength of the tank body and the upper top plate.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model, and are not used to limit the present utility model.

[0018] Please refer to Figure 1 , this application provides a mixing and stirring tank, including a tank body 1. The tank body 1 is made of stainless steel. An upper top plate 12 is arranged above the tank body 1. A discharge port 15 is arranged at the position where the upper part of the tank body 1 is flush with the upper top plate 12. A lower bottom plate 3 is arranged below the tank body 1. A lower inner cylinder 4 is arranged between the lower bottom plate 3 and the inner bottom surface of the tank body 1. Multiple feed pipes 5 are arranged on the outer periphery of the lower inner cylinder 4. Preferably, as Figure 2As shown in the figure, in this embodiment, three feed pipes 5 are provided, namely feed pipe a, feed pipe b, and feed pipe c. Preferably, the feed pipe 5 adopts the siphon feeding method. The feed pipe 5 penetrates to the outside of the tank body 1. A through hole 6 is provided at the center of the lower bottom plate 3. The through hole 6 is located inside the lower inner cylinder 4. A baffle 8 is also provided in the lower inner cylinder 4. The ports of the feed pipes 5 are located on different sides of the baffle 8. When siphon feeding is adopted, the material enters the lower inner cylinder 4 from the feed pipe 5. Due to the presence of the baffle, different materials will not directly impact during feeding, thus avoiding the problem that the material pipe with a small pressure has difficulty in feeding or even cannot feed. A plurality of baffle plates 11 are provided on the inner wall of the tank body 1 to generate turbulent flow for the edge materials, so as to facilitate the uniformity of stirring. The baffle plates 11 are vertically arranged on the inner wall of the tank body 1 between the upper top plate 12 and the lower bottom plate 3.

[0019] A further solution of this embodiment is that in order to realize the stirring of the material, a motor 7 is provided at the top of the tank body 1. The output end of the motor 7 is connected to a rotating shaft 9. The rotating shaft 9 extends into the tank body 1 and stirring blades 10 are provided on the rotating shaft 9. The stirring blades 10 are located above the lower bottom plate 3.

[0020] A flange 51 is provided on the external port of the feed pipe 5, which is convenient for connecting with the material pipeline. In addition, in order to strengthen the strength of the tank body 1, a plurality of reinforcing rings 2 are provided on the outer wall of the tank body 1, and an ear 13 is provided above the tank body 1. A plurality of rib plates 14 are provided between the edge of the upper top plate 12 and the inner wall of the tank body 1, so as to increase the bearing strength of the upper top plate 12 and prevent it from being lifted by the material. An upper inner cylinder 17 is provided at the center of the upper top plate 12.

[0021] In addition, a lower mixing blade 18 is provided at the bottom end of the rotating shaft 9. The lower mixing blade 18 is close to the through hole 6. The gap between the lower mixing blade 18 and the through hole 6 is less than 2 cm, which is conducive to sucking the material into the tank body 1. The working principle of the present utility model is that the material enters the tank body 1 from the feed pipe 5 through the stirring siphon action generated by the stirrer. Due to the blockage of the baffle 8, different materials will not directly impact. The material is stirred by the stirrer 7. As the material in the tank body 1 increases and rises, the stirred material is discharged from the discharge port 15. This device is suitable for the continuous feeding and mixing process.
