Description

Technical Field

[0001] The utility model relates to the technical field of alumina transportation, in particular to a balancing column used on a pneumatic chute. Background Art

[0002] Alumina, a key industrial raw material, is widely used in ceramics, refractories, chemicals, and other fields. Alumina is an inorganic compound composed of aluminum and oxygen, characterized by a high melting point, corrosion resistance, and excellent thermal conductivity. It is widely used in the production of aluminum metal, ceramics, and refractories. Alumina particles typically appear as a white or silvery powder, with a variety of particle sizes and shapes.

[0003] Figure 2 As shown, in the prior art, alumina particles are usually transported pneumatically. The alumina particles are at one end of the pneumatic chute 1 and are pushed to the other end of the pneumatic chute 1 by the air intake of the fan. An air intake pipe 101 is provided at the bottom of the pneumatic chute 1 to lift the flowing alumina particles and make the flow of alumina particles more efficient. A negative pressure pipe 102 is provided at the upper end of the pneumatic chute 1. The high-pressure airflow blown out of the air intake pipe 101 is discharged through the negative pressure pipe 102 to prevent the internal pressure of the pneumatic chute 1 from exceeding the standard. However, the negative pressure pipe 102 requires another supply system. At the same time, part of the airflow of the fan and the alumina particles will also flow into the negative pressure pipe 102, so that the entire pneumatic transportation process consumes a lot of resources. Utility Model Content

[0004] In response to the technical problems existing in the background technology, the purpose of the present utility model is to provide a balance column for use on a pneumatic chute. The balance column replaces the negative pressure pipe, and the excess air pressure is stored in the balance column, thereby avoiding the consumption of alumina particles and reducing the resource pressure of the factory.

[0005] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0006] A balancing column used on a pneumatic chute includes a pneumatic chute and an air intake pipe arranged at the lower end of the pneumatic chute. A pressure relief groove is provided at the upper end of the wind tunnel chute. The balancing column is connected to the pressure relief groove. The balancing column includes a box body and a top cover. The top cover and the box body are detachably connected. The air intake pipe blows air to cause the aluminum oxide inside the pneumatic chute to rise, and part of the air pressure enters the balancing column, so that the air pressure flow in the pneumatic chute is maintained stable.

[0007] Preferably, a filter assembly is provided inside the box, and the filter assembly includes several filter elements and a support plate. The support plate is detachably connected to the inside of the box. The filter element and the support plate are connected, and the airflow will blow part of the alumina powder into the box, and the filter element can adsorb the alumina powder.

[0008] Preferably, a plurality of through holes are provided on the support plate, and the filter element can be detachably inserted in the through holes. A plurality of support grooves are provided on the support plate, and the support grooves and the through holes are concentrically arranged. A connecting plate is provided at one end of the filter element, and the filter element extends into the through hole. The connecting plate is supported in the support groove so that the filter element is supported on the support plate.

[0009] Preferably, the connecting plate is arranged in a circular shape, and the supporting groove is also arranged in a circular shape. A card slot I is arranged on both sides of the supporting groove, and the card slot I passes through the supporting groove. A card plate is arranged on the connecting plate. When the connecting plate and the supporting groove are fitted together, the card plate extends into the card slot I.

[0010] Preferably, a card slot II is provided on one side of the card slot I, and the card slot II is connected to the card slot I. When the card plate extends into the card slot I, the connecting plate can be rotated to allow the card plate to extend into the card slot II.

[0011] Preferably, a threaded hole I is provided on the support plate, and the threaded hole I passes through the support plate and extends into the slot II. A threaded hole II is provided on the card plate, and when the card plate extends into the slot II, the threaded hole I and the threaded hole II are aligned.

[0012] The utility model has the following advantages and beneficial effects:

[0013] In the utility model, the balance column is connected to the pneumatic chute, which increases the internal volume of the pneumatic chute. When the air inlet pipe blows air to lift the alumina inside the pneumatic chute, part of the air pressure enters the balance column, avoiding the increase of the internal pressure of the pneumatic chute, so that the air pressure inside the pneumatic chute remains stable and does not affect the flow of alumina particles. At the same time, the filter element is connected in a detachable manner, which can absorb alumina powder and avoid the alumina powder from wearing the balance column, thereby improving the wear resistance of the balance column. After a period of use, the top cover can be removed, the filter element can be taken out, and a new filter element can be replaced, thereby increasing the service life of the entire structure.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0023] 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 rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0024] Example

[0025] like Figure 1 、 3 As shown in Figure 7, a balancing column used on a pneumatic chute includes a balancing column A, a pneumatic chute 1, and an air intake pipe 101 arranged at the lower end of the pneumatic chute 1. A pressure relief groove 2 is provided at the upper end of the pneumatic chute 1. The balancing column A is connected to the pressure relief groove 2. The balancing column A includes a box body 3 and a top cover 32. The top cover 32 and the box body 3 are detachably connected. The air intake pipe 101 blows air to make the aluminum oxide inside the pneumatic chute 1 rise, and part of the air pressure enters the balancing column A. After circulating in the balancing column A, it is discharged from the balancing column A to the pneumatic chute 1. At the same time, the balancing column A can store part of the air pressure to maintain a stable air pressure flow in the pneumatic chute 1.

[0026] like Figure 1 、3 As shown in , 7, a pad 31 is provided at one end of the box body 3, and the box body 3 and the pneumatic chute 1 are fixedly connected by the pad 31. The interior of the box body 3 is hollow, and a connector 4 is provided between the top cover 32 and the box body 3. The connector 4 is C-shaped, and one end of the connector 4 is connected to the box body 3 by a bolt, and the other end is connected to the top cover 32 by a bolt. After the balancing column A is connected as a whole, the interior of the balancing column A is in a sealed state, and there will be no airflow leakage. On the basis of the existing pressure relief groove 2 structure, the area of the pressure relief groove 2 is increased. When the balancing column A and the pneumatic chute 1 are connected, the balancing column A increases the internal volume of the pneumatic chute 1 so that it can withstand the high-pressure airflow blown in by the air inlet pipe 101. There is no need to re-set the negative pressure pipe 102 to discharge the pressure, which can not only ensure the normal transportation of alumina, but also prevent alumina from being discharged through the negative pressure pipe 102, thereby saving factory resources to a great extent.

[0027] like Figure 1 、 3 As shown in Figures 4, 5, 6, and 7, a filter assembly 5 is provided inside the box body 3. The filter assembly 5 includes several filter elements 52 and a support plate 51. There are several holes on the support plate 51, and air can pass through the support plate 51 from the holes. The support plate 51 is detachably connected to the inside of the box body 3. The support plate 51 and the box body 3 are connected by bolts, which is not only convenient for installation but also convenient for disassembly and replacement during subsequent maintenance. The filter element 52 is connected to the support plate 51, and the air flow will blow part of the alumina powder into the box body 3. The filter element 52 can absorb the alumina powder, thereby avoiding contact between the alumina particles and the inner wall of the balance column A, and reducing the risk of wear and leakage of the balance column A.

[0028] like Figure 1 、 3, 4, 5, and 6, a plurality of through holes 511 are provided on the support plate 51, and the filter element 52 is detachably inserted into the through hole 511. A plurality of supporting grooves 512 are provided on the support plate 51, and the supporting grooves 512 and the through hole 511 are concentrically arranged. A connecting plate 53 is provided at one end of the filter element 52, and the filter element 52 extends into the through hole 511. The connecting plate 53 is supported in the supporting groove 512 so that the filter element 52 is supported on the support plate 51, and the connecting plate 53 is supported in the supporting groove 512 so that the filter element 52 is supported on the support plate 51. 3 is arranged in a circular shape, and the support groove 512 is also arranged in a circular shape. A card slot I 513 is arranged on both sides of the support groove 512, and the card slot I 513 passes through the support groove 512. A card plate 531 is arranged on the connecting plate 53. When the connecting plate 53 and the support groove 512 are fitted, the card plate 531 extends into the card slot I 513. At this time, the filter element 52 will not be able to rotate. A card slot II 514 is arranged on one side of the card slot I 513. The card slot II 514 and the card slot I 513 is connected. When the clamping plate 531 extends into the clamping slot I 513, the connecting plate 53 can be rotated to make the clamping plate 531 extend into the clamping slot II 514. At this time, the movement of the filter element 52 is further restricted, so that it cannot slide up and down in the through hole 511. A threaded hole I 515 is provided on the support plate 51. The threaded hole I 515 passes through the support plate 51 and extends into the clamping slot II 514. The clamping plate 531 is provided with a threaded hole II 532. When the clamping plate 531 extends into the clamping slot II 514, the threaded hole I 515 and the threaded hole II 532 are aligned. The bolts are screwed into the threaded holes I 515 and the threaded holes II 532 to completely fix the filter element 52 and the support plate 51, thereby preventing the filter element 52 from moving due to air pressure during the flow of alumina. At the same time, when replacing the filter element 52, it is only necessary to unscrew the bolts, rotate the filter element 52 to align the clamping plate 531 with the clamping slot I 513, and then pull out the filter element 52.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various changes and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
