Description

Technical field:

[0001] The utility model relates to the technical field of ventilation, in particular to an air supply pipeline filtering mechanism. Background technology:

[0002] The conveying chute from the fresh material bin to the buffer bucket is powered by a fan. The powder enters the chute air chamber through the air supply duct, causing the aluminum powder on the boiling plate to boil. Under the action of wind, it flows forward and enters the buffer bucket. The dust in the channel will also enter the air supply duct through the fan air inlet. A filter mechanism is connected in the air supply duct to block the dust.

[0003] The existing filtering mechanism is mainly composed of multiple sieve plates and collection pipes. The dust blocked by the sieve plates enters the collection pipe for dust collection. The sieve plates are fixedly connected to the air supply duct and cannot be moved. The dust adheres to the side walls of the sieve plates for a long time, causing the sieve holes on the sieve plates to be attached, causing the sieve plates to be blocked. The dust accumulates for a long time and cannot flow into the collection pipe, causing the air supply duct to be blocked, affecting the transportation of alumina powder. Utility model content:

[0004] To this end, the purpose of the utility model is to provide an air supply duct filtering mechanism to overcome the existing technology because the existing filtering mechanism is mainly composed of multiple sieve plates and collecting pipes. The dust blocked by the sieve plates enters the collecting pipe to collect the dust. The sieve plates are fixedly connected to the air supply duct and cannot be moved. The dust adheres to the side walls of the sieve plates for a long time, causing the sieve holes on the sieve plates to be attached, causing the sieve plates to be blocked. The dust accumulates for a long time and cannot flow into the collecting pipe, causing the air supply duct to be blocked, affecting the transportation of alumina powder.

[0005] The utility model is implemented by the following technical solutions:

[0006] A filter mechanism for an air supply duct comprises a fan, wherein the output end of the fan is fixedly connected to the air supply duct, the inner bottom surface of the air supply duct is slidably connected to a plurality of sieve plates via a connecting mechanism, the sieve plates can slide on the sliding mechanism, the bottom surface of the air supply duct is fixedly connected to a plurality of collecting pipes, the collecting pipes are arranged below the sieve plates, and the side walls of the collecting pipes are fixedly connected to valves.

[0007] Preferably, the inner diameter of the air supply duct gradually increases toward the output end of the air supply duct.

[0008] Preferably, the height of the sieve plate increases sequentially along the direction of the output end of the air supply duct.

[0009] Preferably, the top surface of the sieve plate is an inclined surface, and the inclined surface is arranged to be inclined downward along a direction close to the input end of the air supply duct.

[0010] Preferably, the connecting mechanism includes a plurality of guide rods, the guide rods are fixed to the inner bottom surface of the air supply duct, the sieve plate is slidably sleeved on the guide rods, and a return spring is sleeved on the cross bar of the guide rods. The return spring is fittedly arranged on the side wall of the sieve plate and the position where the return spring is arranged is far away from the input end of the air supply duct.

[0011] Preferably, the inclination direction of the collecting pipe is the same as that of the sieve plate, and a plurality of obliquely arranged guide plates are fixedly connected to the inner wall of the collecting pipe from bottom to top, and adjacent guide plates are staggered.

[0012] Preferably, the top surface of the air supply duct is fixedly connected to a high-pressure duct, and the side wall of the high-pressure duct is fixedly connected to a closed valve.

[0013] The advantages of the utility model are as follows: multiple sieve plates are slidably connected in the air supply duct through a connecting mechanism, and the fan drives the dust to move and hit the sieve plates, causing the sieve plates to vibrate. The vibration of the sieve plates vibrates the dust adhered to the side walls of the sieve plates and causes them to flow into the collection pipe, thereby realizing self-cleaning of the dust adhered to the side walls of the sieve plates, reducing the blockage of the sieve holes on the sieve plates, and facilitating the transportation of alumina powder.

[0021] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0022] like Figure 1-Figure 2 As shown, the utility model provides the following technical solutions: an air supply duct filtering mechanism includes a fan 1, the output end of the fan 1 is fixedly connected to an air supply duct 2, the inner bottom surface of the air supply duct 2 is slidably connected to a plurality of sieve plates 5 through a connecting mechanism, the sieve plates 5 can slide on the sliding mechanism, the bottom surface of the air supply duct 2 is fixedly connected to a plurality of collecting pipes 3, the collecting pipes 3 are arranged below the sieve plates 5, and the side walls of the collecting pipes 3 are fixedly connected to valves 4.

[0023] The inner diameter of the air supply duct 2 gradually increases toward the output end of the air supply duct 2 , so that the dust in the air duct 2 can slide into the collection pipe 3 along the inner wall of the air supply duct 2 .

[0024] The height of the sieve plate 5 increases gradually along the direction of the output end of the air supply duct 2, thereby achieving high dust filtration while reducing the obstruction to the wind flow rate.

[0025] The top surface of the sieve plate 5 is an inclined surface and the inclined surface is arranged to be inclined downward along the direction close to the input end of the air supply duct 2, so that the dust falling on the top surface of the sieve plate 5 can flow into the collection pipe 3 along the top surface of the sieve plate 5.

[0026] Please combine Figure 1 As shown, during use, alumina powder is transported, and the fan 1 starts working. The wind containing dust is transported by the fan 1 into the air supply duct 2, and multiple sieve plates 5 are arranged to filter the dust. The dust filtered by the sieve plate 5 flows into the collecting pipe 3 to collect the dust. The flowing dust hits the sieve plate 5, and the sieve plate 5 slides on the connecting mechanism. The sieve plate 5 vibrates to clean the dust adhered to the side wall of the sieve plate 5, so that the adhered dust slides from the side wall of the sieve plate 5 into the collecting pipe 3, thereby realizing self-cleaning of the sieve plate 5, reducing the blockage of the sieve holes on the sieve plate 5, and facilitating the transportation of alumina powder.

[0027] When the dust collected in the collecting pipe 3 needs to be cleaned, the staff unscrews the corresponding valve 4. At this time, the dust in the collecting pipe 3 flows out along the bottom of the collecting pipe 3. The receiving container at the bottom of the collecting pipe 3 prevents the outflowing dust from being collected. After the dust in the collecting pipe 3 is discharged, the corresponding valve 4 is closed.

[0028] Please combine Figure 1 , Figure 2 As shown, an embodiment of the connecting mechanism includes a plurality of guide rods 8, the guide rods 8 are fixed to the inner bottom surface of the air supply duct 2, the sieve plate 5 is slidably sleeved on the guide rods 8, and a return spring 9 is sleeved on the cross bar of the guide rods 8. The return spring 9 is fittedly arranged on the side wall of the sieve plate 5 and the position where the return spring 9 is arranged is far away from the input end of the air supply duct 2.

[0029] Please combine Figure 1 As shown, during use, dust hits the sieve plate 5, causing the sieve plate 5 to move on the guide rod 8 and squeeze the reset spring 9. The squeezed reset spring 9 pushes the sieve plate 5 to reset, thereby achieving the vibration of the sieve plate 5. The vibration of the sieve plate 5 achieves the cleaning of the dust adhered to the side wall of the sieve plate 5.

[0030] The inclination direction of the collecting pipe 3 is the same as that of the sieve plate 5 . A plurality of obliquely arranged guide plates 6 are fixedly connected to the inner wall of the collecting pipe 3 from bottom to top, and adjacent guide plates 6 are staggered.

[0031] Please combine Figure 1 As shown, during use, the inclination direction of the collecting pipe 3 is the same as the inclination direction of the sieve plate 5, so that the dust filtered by the sieve plate 5 flows into the collecting pipe 3 along the sieve plate 5, reducing the resistance of the wind to the flow of dust, and the dust entering the collecting pipe 3 flows to the bottom of the collecting pipe 3 along multiple guide plates 6 in turn. The setting of multiple guide plates 6 reduces the contact area between the wind and the dust entering the collecting pipe 3, thereby reducing the dust entering the collecting pipe 3 from being blown out again by the wind.

[0032] The top surface of the air supply duct 2 is fixedly connected with a high-pressure duct 7, and the side wall of the high-pressure duct 7 is fixedly connected with a closed valve.

[0033] Please combine Figure 1 As shown, during use, when the dust in the air supply duct 2 and the collecting pipe 3 needs to be cleaned, open the sealing valve and valve 4, and introduce high-pressure gas from the input end of the high-pressure pipe 7. The dust in the air supply duct 2 is blown out along the collecting pipe 3, so as to clean the dust in the air supply duct 2 and the collecting pipe 3. After cleaning, close the sealing valve and valve 4.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
