[0020] In order to more clearly illustrate the technical solutions in the embodiments of the present application or related technologies, the following will be described clearly and completely in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0021] In the electrolytic aluminum industry, a super-dense phase conveying system is generally used to transport alumina. The super-dense phase conveying system of alumina includes a transport chute, which introduces a certain amount of gas into the powder material to make the powder material flowable, so that the mixed material can be transported in the chute. In the related technology, the chute has a material chamber for transporting materials and an air chamber for introducing air. Due to the long-term operation of the chute, some materials will penetrate from the material chamber to the air chamber. The long-term accumulation of materials in the air chamber will cause the material to move slowly in the chute. In addition, if the staff wants to clean the materials accumulated in the air chamber, they need to close the feeding of the chute first, which will result in less material removal and affect the transportation stability of the materials.
[0022] For the above situation, please see Figure 1 The present application proposes a conveying device 1 for use in a super dense phase conveying system, for example, for transporting super dense phase alumina. The conveying device 1 includes a main body 10 and an air intake pipe 20.
[0023] The main body 10 has a receiving chamber 11, and a partition 12 is arranged in the receiving chamber 11. The partition 12 divides the receiving chamber 11 into a first cavity 111 and a second cavity 112 which are independent of each other. The first cavity 111 is used to introduce air to form a first airflow with a relatively uniform flow rate. The second cavity 112 is used to receive and transport materials. The materials are in contact with the partition 12. At this time, the first airflow acts on the partition 12, and the partition 12 vibrates, so that the partition 12 can drive part of the materials in the second cavity 112 to move. Among them, the materials put into the second cavity 112 can be a mixture of powdered materials such as aluminum oxide and gas.
[0024] The air intake pipe 20 is in communication with the first cavity 111, and the air intake pipe 20 is used to pass compressed gas into the first cavity 111 to clean the first cavity 111. It should be noted that the air intake pipe 20 passes compressed gas, and the pressure of the compressed gas is greater than the atmospheric pressure. After the compressed gas enters the first cavity 111, a second airflow is formed in the first cavity 111, and the flow rate of the second airflow is faster than the flow rate of the first airflow. The second airflow impacts the materials accumulated in the first cavity 111, and clears the accumulated materials out of the first cavity 111, thereby reducing the accumulation of materials in the first cavity 111.
[0025] It should be noted that in the embodiment of the present application, an air intake pipe 20 for introducing compressed gas is provided, and the air intake pipe 20 is connected to the first cavity 111, so that when material is accumulated in the first cavity 111, the air intake pipe 20 can be emptied promptly and quickly, reducing the accumulation of materials in the first cavity 111, and preventing the main body 10 from moving slowly, thereby improving the transportation efficiency of the conveying device 1. At the same time, during the transportation of the main body 10, the embodiment of the present application can also clean the first cavity 111 synchronously, without interrupting the feeding process of the second cavity 112, that is, without stopping the conveying device 1 for cleaning, thereby preventing the lack of material due to the long-term cessation of feeding to the second cavity 112, thereby improving the stability of material transportation.
[0026] Among them, the air intake pipe 20 is a metal pipe. Since the air intake pipe 20 is used to pass compressed gas, the air pressure is relatively high, and the strength of the metal pipe is relatively high. The compressed gas is transported in the metal pipe, which can reduce the deformation of the air intake pipe 20 and extend the service life of the air intake pipe 20.
[0027] Please continue to see Figure 1 In some embodiments of the present application, the first cavity 111 and the second cavity 112 are arranged vertically, and the second cavity 112 is located above the first cavity 111. During the transportation of the material, part of the material in the second cavity 112 falls onto the partition 12 under the action of gravity, and the partition 12 vibrates under the action of the first airflow to drive part of the material on the partition 12 to move. The extension direction of the first cavity 111 is parallel to the extension direction of the second cavity 112, so as to facilitate the transportation of the material in the second cavity 112.
[0028] Furthermore, in some embodiments of the present application, the partition 12 includes an elastic fabric layer, which not only reduces production costs but also facilitates the transportation of materials.
[0029] Specifically, taking the separator 12 including a canvas layer as an example, the separator 12 separates the first cavity 111 and the second cavity 112, materials are put into the first cavity 111, and part of the materials fall onto the separator 12 under the action of gravity, and air is passed into the second cavity 112, and the air forms a first airflow in the second cavity 112, and the first airflow can drive the canvas layer of the separator 12 to vibrate, and at this time, the canvas layer drives the materials on the separator 12 to move. Among them, the separator 12 can be made of a cloth with a relatively high density to reduce the penetration of materials from the second cavity 112 into the first cavity 111.
[0030] Please continue to see Figure 1 In some embodiments of the present application, the conveying device 1 further includes a control valve 30 , which is disposed between the air intake pipe 20 and the main body 10 , and is used to control the opening and closing of the air intake pipe 20 .
[0031] Specifically, when materials are accumulated in the first cavity 111, the control valve 30 can be opened to pass compressed gas into the air intake pipe 20, so that the compressed gas enters the first cavity 111 from the air intake pipe 20 to clean up the accumulated materials in the first cavity 111. The control valve 30 can be set as a timing valve, so that the air intake pipe 20 can be opened at a fixed time, so that the air intake pipe 20 can pass compressed gas into the first cavity 111 at a fixed time, thereby improving the working efficiency of the conveying device 1.
[0032] Furthermore, in some embodiments of the present application, the control valve 30 includes a ball valve. Since the ball valve has a simple structure and is easy to operate, the staff can quickly perform switch control, and the opening and closing time is short. At the same time, the valve seat material of the ball valve is generally an elastic material, so that the ball valve has good sealing performance, thereby preventing the air in the first cavity 111 from leaking from the intake duct 20.
[0033] See also Figure 2 In some embodiments of the present application, the main body 10 is tilted, the first end of the main body 10 is located above the second end of the main body 10 , and the air intake duct 20 is connected to the first end of the main body 10 .
[0034] It can be understood that the material in the second cavity 112 can slide along the inclined direction of the main body 10. At the same time, part of the material that penetrates from the second cavity 112 into the first cavity 111 accumulates in the first cavity 111. When compressed gas is introduced into the air intake pipe 20, the compressed gas can flow along the inclined direction of the main body 10 to take away the material in the first cavity 111. Therefore, the inclined setting of the main body 10 facilitates guiding the material in the accommodating cavity 11.
[0035] For further information, please see Figure 2In some embodiments of the present application, the main body 10 further has a first opening 13, which is located at the second end of the main body 10, and the first opening 13 is connected to the first cavity 111, so that the compressed gas can drive the material in the first cavity 111 to leave the first cavity 111 through the first opening 13, so as to reduce the accumulation of the material in the first cavity 111 and prevent the first cavity 111 from being blocked due to excessive accumulation of the material.
[0036] In some embodiments, a plurality of first openings 13 may be provided on the main body 10, and the plurality of first openings 13 are arranged at intervals along the extension direction of the first cavity 111 on the main body 10, so that the materials accumulated in various parts of the first cavity 111 can be cleaned out from the first openings 13 as soon as possible. At the same time, a plurality of first valves may be provided on the main body 10, and a first valve is provided at each first opening 13, and the opening and closing of the first opening 13 are controlled by the opening and closing of the first valve. Among them, different first valves may be opened at the same time; or different first valves may be opened successively, for example, the first valve near the first end is opened first, and when the materials there are cleaned, the next first valve is opened in sequence from the first end to the second end for cleaning, that is, along the direction from the first end to the second end, each first valve is opened for a period of time and then closed, so that the materials in various parts of the first cavity 111 are cleaned more completely.
[0037] Please continue to see Figure 2 In some embodiments of the present application, the main body 10 further has a second opening 14, which is connected to the second cavity 112. The second opening 14 can be used to clean the excess or deposited materials in the second cavity 112. It is easy to understand that the second cavity 112 is used to transport materials. During a long period of transportation, the materials in the second cavity 112 will be partially deposited. The staff can clean the second cavity 112 through the second opening 14 to reduce the deposition of materials in the second cavity 112, so as to improve the working efficiency of the conveying device 1.
[0038] Similarly, a plurality of second openings 14 may be provided, and the plurality of second openings 14 may be arranged at intervals along the extension direction of the second cavity 112 on the main body 10, so that materials deposited in various parts of the second cavity 112 can be cleaned out from the second openings 14 as quickly as possible. A plurality of second valves may also be provided on the main body 10, and a second valve is provided at each second opening 14, and the opening and closing of the second opening 14 is controlled by the opening and closing of the second valve.
[0039] See also Figure 1-Figure 2In some embodiments of the present application, the conveying device 1 also includes a dust box 40 connected to the main body 10, and the dust box 40 is communicated with the second cavity 112. The material put into the second cavity 112 can be screened and collected by the dust box 40 to remove some dust and impurities mixed in the material, so as to facilitate subsequent processing of the material.
