A composite mixing tank with wear-resistant inner wall and turbulent flow control.

Abstract

This utility model relates to a composite mixing tank with a wear-resistant inner wall and turbulent flow control. The mixing shaft is connected to a power unit, and a first and second fan blades are mounted in opposite directions on the mixing shaft. A grate is fixed to the lower 1 / 3 of the tank body, located between the second fan blade and the mixing chain. The mixing chain is mounted on the mixing shaft and linked with the grate. The beneficial effects of this utility model are: the slurry is mixed more thoroughly inside the tank; the grate acts as a filter, isolating stones, lumps, etc., larger than the mesh size. Under the centrifugal rotation of the mixing chain, these are further broken down until the lumps are dispersed and the particle size is smaller than the grate mesh diameter, allowing them to fall to the bottom of the tank. After being mixed again by the second fan blade, they are discharged outside the tank. The composite mixing process prevents large particles from being discharged outside the tank and clogging the pipes, while also ensuring more uniform mixing of the mortar, achieving an ideal mixing effect. The wear-resistant rubber effectively reduces wear on the tank body and can be replaced periodically, extending the tank's service life.

Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, and in particular to a composite mixing tank with wear-resistant inner wall and turbulent flow. Background Technology

[0002] With the expansion of industrial production scale and the improvement of product quality requirements, traditional simple mixing equipment can hardly meet the needs of efficient, uniform mixing and precise control, thus prompting continuous innovation in mixing tank technology.

[0003] Early mixing tanks suffered from problems such as uneven mixing, low efficiency, easy wear, and difficulty in cleaning. Furthermore, some mixing tanks had poor mixing performance, easily causing material agglomeration, affecting product quality, and clogging the discharge pipe. Other mixing tanks lacked sufficient mixing power when handling high-viscosity materials or in large-scale production, failing to achieve the desired mixing effect. These shortcomings of existing technologies have become the driving force for the development of new mixing tanks, propelling the advancement of related technologies to solve these practical application problems. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, this utility model provides a composite stirring tank with wear-resistant inner wall and turbulent flow.

[0005] A composite stirring tank with wear-resistant inner wall and turbulent flow, comprising a tank body, a power unit, and a stirring shaft, characterized in that:

[0006] The stirring shaft is connected below the power unit, and the first and second blades are installed in opposite directions on the stirring shaft; a grate is fixed at the lower 1 / 3 of the barrel body, and the grate is located between the second blade and the stirring chain; the stirring chain is installed on the stirring shaft and is linked with the grate.

[0007] Furthermore, in order to better realize this utility model, the inner wall of the barrel is adhered with wear-resistant rubber, and the wear-resistant rubber is screwed and pressed to the turbulence sleeve through the connecting screw that penetrates the barrel.

[0008] Furthermore, in order to better realize this utility model, the first fan blade rotates downward to press the slurry, and the second fan blade rotates upward to lift the slurry, so that the two form a convective stirring.

[0009] Furthermore, in order to better realize this utility model, the stirring chain rotates closely against the grate under the action of centrifugal force, and is supported and positioned by the grate when the machine stops.

[0010] Furthermore, in order to better realize this utility model, the grate is provided with uniform mesh holes to isolate large particles and achieve secondary crushing when the stirring chain rotates.

[0011] Furthermore, in order to better realize this utility model, the turbulence sleeve is fitted outside the connecting screw, and its outer wall protrudes to form an internal turbulence structure.

[0012] Furthermore, in order to better realize this utility model, the turbulence sleeve and the connecting screw form a detachable connection, and the wear-resistant rubber is a replaceable consumable part.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention utilizes a stirring shaft to drive the first and second blades and a stirring chain to rotate. The first blade downwards compresses the slurry inside the bucket, while the second blade lifts it upwards, resulting in more thorough mixing. Simultaneously, a grate installed and fixed at the bottom third of the bucket acts as a filter, isolating stones and lumps larger than the mesh size. Under the centrifugal rotation of the stirring chain, these particles are further broken up until they are dispersed and smaller than the grate mesh diameter, allowing them to fall to the bottom of the bucket. After being further stirred by the second blade, they are discharged from the bucket. This combined mixing process prevents large particles from clogging the pipes and ensures more uniform mixing, achieving the desired mixing effect. The wear-resistant rubber adhering to the inner wall of the bucket effectively reduces wear on the bucket. As a consumable part, the rubber can be replaced periodically, extending the bucket's lifespan and creating greater economic value. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Figures 1-3 This is a specific embodiment of the present invention, which is a composite stirring and wear-resistant turbulence stirring tank with an inner tank wall. A power unit 9 is fixedly installed at the center of the upper part of the tank body 1, providing rotational power to the stirring shaft 4; the stirring shaft 4 is connected to the power unit 9 and rotates inside the tank; the first fan blade 2, the second fan blade 3, and the stirring chain 6 are all installed on the stirring shaft 4; a grate 5 is fixed inside the tank body, with evenly distributed mesh holes, and is fixed at the lower 1 / 3 of the tank body 1, between the second fan blade 3 and the stirring chain 6; when the stirring chain 6 is working, it rotates tightly against the grate 5 under centrifugal force; when stopped, the grate 5 supports the stirring chain 6; a connecting screw 101 penetrates the tank body and is welded firmly to prevent leakage; a turbulence sleeve 8 has internal threads and can be screwed onto the connecting screw 101. Wear-resistant rubber 7 is adhered to the inner wall of the tank body 1, and the turbulence sleeve 8 and the connecting screw 101 are used to press the wear-resistant rubber 7 firmly onto the tank body 1, providing reinforcement. The baffle sleeve 8, fixedly installed on the connecting screw 101, not only protects the threads of the connecting screw 101 and prevents wear from affecting the later replacement of the wear-resistant rubber 7, but also works with the fan blades and stirring chain 6 to improve the stirring effect. The first fan blade 2 and the second fan blade 3 rotate in different directions. When the stirring shaft 4 is working normally, the first fan blade 2 pushes the slurry in the tank downward, while the second fan blade 3 lifts the slurry upward, making the slurry more thoroughly stirred in the tank.

[0023] The specific implementation method of this embodiment is as follows:

[0024] The power unit 9 is installed at the top of the tank 1 and connected to the stirring shaft 4, providing rotational power. The first fan blade 2, the second fan blade 3, and the stirring chain 6 are installed on the stirring shaft 4. The grate 5 is installed and fixed at the lower 1 / 3 of the tank 1, between the second fan blade 3 and the stirring chain 6, and can act as a filter. Stones, lumps, etc. larger than the mesh size are isolated on the grate 5. Under the centrifugal rotation of the stirring chain 6, they can be broken up again until the lumps are dispersed. Only when the particle size is smaller than the diameter of the grate mesh can they fall to the bottom of the tank. After being stirred again by the second fan blade 3, they are discharged outside the tank, preventing large particles from clogging the pipes.

[0025] The stirring shaft 4 drives the first blade 2, the second blade 3, and the stirring chain 6 to rotate. The first blade 2 compresses the slurry in the tank downwards, while the second blade 3 lifts the slurry upwards, making the slurry more thoroughly mixed in the tank. Due to the centrifugal rotation of the slurry, under the action of the turbulence sleeve 2 fixed on the inner wall of the tank 1, large particles in the slurry are further crushed, improving the uniformity of mixing and achieving the ideal mixing effect.

[0026] The wear-resistant rubber 7 adhering to the inner wall of the barrel 1 can effectively reduce the wear of the mortar on the barrel 1. As a consumable part, the wear-resistant rubber 7 can be replaced regularly, thereby increasing the service life of the barrel 1 and creating higher economic value.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
