[0021] 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.
[0022] In the electrolytic aluminum industry, an ultra-dense phase conveying system of alumina is used to introduce 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 process of feeding the material into the chute, if there is a lot of material in the chute, it is easy to cause excessive air pressure in the dust box and material accumulation. The dust box is not depressurized in time, which will cause a high pressure in the chute, slow material flow or no flow, thus affecting environmental protection data and material stability.
[0023] For the above situation, please see Figure 1 The present application proposes a conveying device 1 for a super dense phase conveying system, comprising a main body 10, a dust collecting box 20 and a pressure relief pipe 30. The main body 10 has a conveying trough 11, and the conveying trough 11 is used to convey materials. The conveying device 1 in this embodiment can be used to transport super dense phase alumina, and the material put into the conveying trough 11 can be a mixture of powdered materials such as alumina and gas.
[0024] The dust box 20 is arranged above the main body 10 and connected to the main body 10. The dust box 20 is communicated with the transport trough 11. The material put into the transport trough 11 can be screened and collected by the dust box 20 to collect part of the powdered material and some fine dust mixed in the material, so as to facilitate the subsequent processing of the material; the pressure relief pipe 30 connects the dust box 20 and the outside world, and guides the excess gas in the dust box 20 to the outside world, so as to relieve the pressure of the dust box 20 and the transport trough 11, so that the material in the transport trough 11 can be transported normally.
[0025] It should be noted that if too much material is put into the main body 10, a large amount of gas will accumulate in the transport trough 11 and the dust box 20. The air pressure in the transport trough 11 and the dust box 20 is too high, which will cause the material in the transport trough 11 to flow slowly. The embodiment of the present application is provided with a pressure relief pipe 30 connecting the dust box 20 and the outside world, so that the pressure relief pipe 30 can guide the excess gas in the dust box 20 to the outside world, thereby relieving the pressure in the dust box 20, reducing the air pressure in the dust box 20 and the transport trough 11, so that the material can be transported normally in the transport trough 11.
[0026] In some embodiments, the main body 10 can be tilted, and the transport trough 11 can be tilted. After the material is put into the transport trough 11, the material can flow along the tilted direction of the main body 10. The tilted setting of the main body 10 facilitates guiding the material in the transport trough 11.
[0027] Among them, the pressure relief pipe 30 is a metal pipe. Since the air pressure in the dust box 20 is relatively high, the pressure relief pipe 30 is used to discharge the gas in the dust box 20. The strength of the metal pipe is relatively high. The gas is transported in the metal pipe, which can reduce the deformation of the pressure relief pipe 30 due to the high air pressure and extend the service life of the pressure relief pipe 30.
[0028] Further, in some embodiments of the present application, a seal is provided between the pressure relief pipe 30 and the dust box 20, thereby preventing the gas in the dust box 20 from leaking from the connection between the pressure relief pipe 30 and the dust box 20. The pressure relief pipe 30 can be connected to the dust box 20 by welding, gluing, clamping, riveting, threading or other methods.
[0029] The pressure relief pipe 30 can be used to exhaust the dust box 20. In some embodiments of the present application, the diameter of the pressure relief pipe 30 is smaller than the inner diameter of the transport trough 11. Therefore, the setting of the pressure relief pipe 30 can reduce the material in the dust box 20 and the transport trough 11 from being discharged along with the gas, thereby reducing the loss of material and saving production costs.
[0030] Please continue to see Figure 1 In some embodiments of the present application, the dust collecting box 20 includes a box body 21 and a dust collecting bag 22 disposed in the box body 21 . The box body 21 and the dust collecting bag 22 are both connected to the transport trough 11 , and the box body 21 is connected to the pressure relief pipe 30 .
[0031] It should be noted that after the mixed material enters the transport trough 11, it can enter the dust bag 22. The dust bag 22 can screen and collect the powdered material in the mixed material. Then, under the action of gravity inertia, the coarse dust particles in the gas can fall into the transport trough 11 for continued transportation. If the air pressure in the transport trough 11 and the dust box 20 is too high, the coarse material in the dust bag 22 cannot fall into the transport trough 11. After the pressure is relieved through the pressure relief pipe 30 in this embodiment, the air pressure in the box 21 is reduced, and the pressure difference between the inside and outside of the dust bag 22 is restored to the state at the beginning of use. At this time, the coarse material in the dust bag 22 can smoothly fall into the transport trough 11 for subsequent transportation and production.
[0032] Specifically, the dust bag 22 is made of a flexible, breathable material, such as a needle-punched or coated material, so that the dust bag 22 can filter the mixed material. The working principle of the dust bag 22 for screening and collecting powdered materials has been disclosed in the relevant technology and will not be described here.
[0033] For further information, see Figure 1-Figure 2 In some embodiments of the present application, the box body 21 has a first cavity 211 and a second cavity 212 that are interconnected. The first cavity 211 and the second cavity 212 are arranged vertically, and the first cavity 211 is located above the second cavity 212. The pressure relief pipe 30 is connected to the first cavity 211, and the dust bag 22 is arranged in the second cavity 212.
[0034] Specifically, the pressure relief pipe 30 is used to relieve pressure in the dust box 20 to discharge excess gas accumulated in the dust box 20. The pressure relief pipe 30 and the dust bag 22 are spaced apart so that the pressure relief pipe 30 and the dust bag 22 can work independently, thereby reducing interference between the dust bag 22 and the pressure relief pipe 30.
[0035] See also Figure 3 In some embodiments of the present application, the dust box 20 also includes a guide member 23 arranged between the box body 21 and the main body 10, and the guide member 23 has an inclined guide surface, which is used to guide the material from the transport trough 11 to the dust box 20.
[0036] Specifically, the material in the transport trough 11 can slide along the guide surface on the guide member 23 and enter the box body 21. It should be noted that the guide member 23 can be annular as a whole, the inner edge of the guide member 23 is connected to the main body 10, the outer edge of the guide member 23 is connected to the box body 21, and the guide member 23 is inclined upward from the inner edge to the outer edge, so that the material in the transport trough 11 can enter the box body 21 from various directions. Among them, the guide member 23 is sealed with the box body 21 and the main body 10, and the guide member 23 can be connected to the box body 21 and the main body 10 by welding, gluing, clamping, riveting, threading or other methods.
[0037] See also Figure 1 and Figure 3 In some embodiments of the present application, the conveying device 1 also includes a negative pressure fan 40, one end of the pressure relief pipe 30 is connected to the dust collecting box 20, and the other end of the pressure relief pipe 30 is connected to the negative pressure fan 40, and the negative pressure fan 40 is used to form a negative pressure inside the pressure relief pipe 30.
[0038] It is understandable that the negative pressure fan 40 sucks air from the inside of the pressure relief pipe 30 to the outside of the pressure relief pipe 30, so as to extract the gas in the pressure relief pipe 30 and the box 21. When too much material is put into the main body 10, a large amount of gas is accumulated in the transport trough 11 and the dust box 20, and the air pressure increases, the pressure relief pipe 30 can quickly discharge the gas in the dust box 20 due to the internal negative pressure to reduce the air pressure in the dust box 20. Among them, the staff can control the switch of the negative pressure fan 40 according to the specific exhaust situation of the pressure relief pipe 30, so that the air pressure in the dust box 20 can be restored as soon as possible.
[0039] In some embodiments, Figure 2 As shown, the conveying device 1 includes a flue for discharging flue gas. Since the flue is generally in a negative pressure state, the pressure relief pipe 30 can be connected to the dust box 20 and the flue, and the gas in the dust box 20 is discharged through the negative pressure of the flue. At the same time, the gas discharged from the flue can flow through the flue and then undergo purification and other operations to reduce pollution to the environment.
[0040] See also Figure 2 In some embodiments of the present application, the conveying device 1 further includes a one-way valve 50, which is disposed between the pressure relief pipe 30 and the dust box 20. The one-way valve 50 is used to allow the gas in the dust box 20 to flow out to the outside. It is easy to understand that when the air pressure in the dust box 20 is relatively high, the gas in the dust box 20 can push open the one-way valve 50 and flow into the pressure relief pipe 30 from the one-way valve 50, so as to reduce the pressure in the dust box 20. When the air pressure in the dust box 20 returns to normal, the one-way valve 50 is closed, and the gas in the dust box 20 continues to flow in the dust box 20 and the transport trough 11, and cannot flow out through the pressure relief pipe 30, thereby facilitating the one-way exhaust of the dust box 20 from the inside to the outside. At the same time, the one-way valve 50 does not require the staff to manually adjust the switch, thereby improving production efficiency.
[0041] The gas-mixed powdered material is put into the main body 10 and flows in the transport trough 11. The gas drives part of the powdered material into the dust collecting box 20. Under the action of gravity, most of the powdered material is located in the dust collecting box 20 near the main body 10. In some embodiments of the present application, Figure 1-Figure 3 As shown, the pressure relief pipe 30 is disposed at one end of the dust collecting box 20 away from the main body 10, thereby reducing the powdered material carried in the gas discharged from the pressure relief pipe 30, thereby reducing the loss of material and saving production costs.
