Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a combination for conveying powdery materials. Background Technology

[0002] Material handling refers to a series of operations and equipment combinations designed to achieve the smooth transportation and efficient processing of materials. Material handling is an indispensable part of industrial production. It involves the process of moving raw materials, semi-finished products or finished products from one location to another. This process is crucial for maintaining the continuity and efficiency of the production line, while also helping to reduce production costs and improve product quality.

[0003] In the current electrolytic aluminum industry, the demand for conveying capacity of fresh alumina conveying systems is increasing. However, traditional dense phase conveying systems, even with the combination of pressure tanks and dense phase pipelines, are still inadequate, with limited conveying capacity. In addition, the problem of pipeline wear is becoming increasingly serious, and the material breakage rate remains high. This not only significantly reduces the efficiency of material use, but also poses a serious challenge to improving the current efficiency and stable operation of electrolytic cells. Utility Model Content

[0004] The purpose of this invention is to provide a combination for conveying powdered materials, which has the advantages of large material conveying capacity, reduced material breakage rate, reduced compressed air consumption, and long-distance high-flow conveying, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combination for conveying powdered materials, comprising a first chute, a discharge hopper connected to the top of the first chute, a second chute connected to one side of the first chute, a first exhaust device fixedly connected to the top of the second chute, a third chute connected to one end of the second chute, a second exhaust device fixedly connected to the top of the third chute, a bucket elevator provided on one side of the third chute, one end of the third chute connected to the feed port of the bucket elevator, a fourth chute connected to the discharge port of the bucket elevator, a third exhaust device fixedly connected to the top of the fourth chute, a material storage silo connected to one end of the third exhaust device, a first centrifugal fan fixedly connected to one side of the second chute, a first main air supply pipe connected to one side of the second chute, a second centrifugal fan fixedly connected to one side of the third chute, a second main air supply pipe connected to one side of the third chute, a third main air supply pipe provided in the inner cavity of the material storage silo, and a third centrifugal fan provided on the surface of the third main air supply pipe.

[0006] Furthermore, as a preferred embodiment of this invention, there are several second chutes and several third chutes, which are distributed in an alternating pattern.

[0007] Furthermore, as a preferred embodiment of this utility model, both the first chute and the second chute are inclined, and the inclination angle of the second chute is smaller than that of the first chute.

[0008] Furthermore, as a preferred embodiment of this invention, the bottom of both the first chute and the second chute are fixedly connected to support legs, and the two support legs are at different heights.

[0009] Furthermore, as a preferred embodiment of this invention, a box door is rotatably connected to the surface of the first exhaust device, and the box door is rectangular in shape.

[0010] Beneficial effects: The technical solution of this application has the following technical effects: This utility model has the advantages of large material conveying capacity, reduced material breakage rate, reduced compressed air consumption, and long-distance high-flow conveying. In actual use, by precisely controlling the air supply, the alumina powder is made to flow as smoothly as a liquid during the conveying process, reducing material breakage caused by collision and squeezing. At the same time, the reasonable chute inclination angle design also reduces the impact force of the material during the conveying process. While ensuring the fluidization of the material, the amount of compressed air used is minimized. In addition, the fluidized conveying method also reduces energy consumption and improves the overall conveying efficiency.

[0020] As attached Figure 1 To be continued Figure 5 As shown: This embodiment provides a combination for conveying powdered materials, including a first chute 1, with a discharge hopper 2 connected to the top of the first chute 1, a second chute 3 connected to one side of the first chute 1, a first exhaust device 4 fixedly connected to the top of the second chute 3, a third chute 5 connected to one end of the second chute 3, a second exhaust device 6 fixedly connected to the top of the third chute 5, a bucket elevator 7 arranged on one side of the third chute 5, one end of the third chute 5 connected to the feed port of the bucket elevator 7, and the discharge port of the bucket elevator 7 connected to... There is a fourth chute 8, and a third exhaust device 9 is fixedly connected to the top of the fourth chute 8. One end of the third exhaust device 9 is connected to the material storage bin 10. A first centrifugal fan 11 is fixedly connected to one side of the second chute 3. A first air supply main pipe 12 is connected to one side of the second chute 3. A second centrifugal fan 13 is fixedly connected to one side of the third chute 5. A second air supply main pipe 14 is connected to one side of the third chute 5. A third air supply main pipe 16 is provided in the inner cavity of the material storage bin 10. A third centrifugal fan 15 is provided on the surface of the third air supply main pipe 16.

[0021] Specifically, there are several second sluices 3 and several third sluices 5, and these several second sluices 3 and several third sluices 5 are distributed alternately.

[0022] Specifically, both the first chute 1 and the second chute 3 are inclined, and the inclination angle of the second chute 3 is smaller than that of the first chute 1.

[0023] In this embodiment, the inclined arrangement of the first chute 1 and the second chute 3 facilitates the feeding of powdered materials, making it less likely to cause blockage in the inner cavity of the first chute 1 and the second chute 3.

[0024] Specifically, the bottom of both the first chute 1 and the second chute 3 is fixedly connected with support legs 17, and the two support legs 17 are at different heights.

[0025] In this embodiment, the support leg 17 serves to support the first chute 1 and the second chute 3, thereby improving the stability of the first chute 1 and the second chute 3 during placement.

[0026] Specifically, a door 18 is rotatably connected to the surface of the first exhaust device 4, and the door 18 is rectangular in shape.

[0027] In this embodiment: With the setting of the box door 18, when the first exhaust device 4 is damaged, the user can open the first exhaust device 4 by turning the box door 18, which makes it convenient for the user to repair and replace the internal parts of the first exhaust device 4.

[0028] The working principle and usage process of this utility model are as follows: Alumina powder passes through multiple discharge hoppers 2 and then enters the inner cavity of the second chute 3 via the first chute 1. Under the action of the first centrifugal fan 11, the first main valve is connected to the first air supply main pipe 12. A first air supply branch pipe is set at a suitable position on the first air supply main pipe 12 to supply air to the second chute 3, so that the alumina powder in the second chute 3 has fluidized properties. At this time, the state is like water, with good fluidity. Under the action of the material potential energy brought by the external force of the chute angle, the alumina powder can generate directional movement. The excess useless air volume is harmlessly discharged through the first exhaust device 4 set on the surface of the second chute 3. The multiple sections of the second chute 3 are connected to the multiple sections of the third chute 5, and the third chute 5 supplies air. A second main air supply pipe 14 is used, which is connected to the second main air supply pipe 14 by setting a second main pipe valve. A second branch air supply pipe is set at a suitable position on the second main air supply pipe 14 to supply air to the third chute 5. A second exhaust device 6 is set on the surface of the third chute 5. As the alumina powder moves continuously, the alumina powder will enter the bucket elevator 7. The bucket elevator 7 lifts the alumina powder to the desired conveying position and then conveys it to the fourth chute 8. The fourth chute 8 is supplied with air by a third centrifugal fan 15, which is connected to the third main air supply pipe 16 by setting a third main pipe valve. A third branch air supply pipe is set at a suitable position on the third main air supply pipe 16 to supply air to the fourth chute 8. Finally, the alumina powder is conveyed to the inner cavity of the material storage silo 10 for storage.

Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
