Description

Technical Field

[0001] This utility model relates to the field of degassing technology for ultrafine powders, and in particular to an online degassing device for ultrafine powder silos. Background Technology

[0002] Ultrafine powder is a new type of material with special physicochemical properties. It refers to powder materials with a particle size of less than micrometers, which are in the submicron or even nanometer range. It is composed of a large number of tiny particles. The extremely small size of these particles gives ultrafine powders different characteristics from conventional particulate materials.

[0003] The online degassing device for ultrafine powder silos is a piece of equipment used to solve various problems caused by the presence of gas in ultrafine powder silos. Its main function is to remove gas mixed in with ultrafine powder in real time during the storage and transportation of powder materials, preventing powder from agglomerating, bridging, and obstructing unloading, ensuring that the powder material can flow smoothly out of the silo for subsequent processing. In the past, online degassing of ultrafine powder silos was achieved by manual stirring, while now it is achieved by mechanized degassing through the online degassing device. The existing online degassing device for ultrafine powder silos intercepts dust during degassing by using a filter screen on the outer casing of the pushing device. However, this interception method causes some dust to be squeezed out during pushing, resulting in blockage of the suction pipe. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an online degassing device for ultrafine powder silos, aiming to improve the problem in the existing interception method where some dust is squeezed out during pushing, causing the exhaust pipe to be blocked.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an online degassing device for an ultrafine powder silo, comprising a frame, a motor fixedly connected to the top of the frame, a rotating rod fixedly connected to the output end of the motor, a spiral blade fixedly connected to the lower middle part of the outer wall of the rotating rod, an outer tube fixedly connected to the middle inner side of the frame, a double-layer filter screen fixedly connected to the inner side of the outer tube, a connecting pipe connected to the right side of the outer tube, an air pump connected to the end of the connecting pipe, and a discharge rate adjustment mechanism installed at the bottom of the outer tube for adjusting the discharge speed of the outer tube outlet.

[0006] As a further description of the above technical solution:

[0007] The shipment volume adjustment mechanism includes adjustment blocks, the upper and lower ends of multiple adjustment blocks are slidably connected to the upper inner end of the outer tube, the lower inner end of the outer tube is rotatably connected to a turntable, the inner top wall of the outer tube is provided with a sliding groove, the top of the outer wall of the turntable is provided with multiple guide grooves at equal intervals, the bottom of the turntable is fixedly connected with connecting rods at equal intervals, and the bottom of each of the multiple connecting rods is fixedly connected with an adjustment ring.

[0008] As a further description of the above technical solution:

[0009] The bottom of the outer wall of the air pump is fixedly connected to a mounting bracket, and each of the four corners of the mounting bracket is threaded with a screw.

[0010] As a further description of the above technical solution:

[0011] A fixing ring is fixedly connected to the left end of the connecting pipe, and an intercepting net is fixedly connected to the inner wall of the fixing ring.

[0012] As a further description of the above technical solution:

[0013] A rubber sleeve is fixedly connected to the outer wall of the adjusting ring, and the outer wall of the rubber sleeve is provided with anti-slip texture.

[0014] As a further description of the above technical solution:

[0015] Stabilizers are fixedly connected at equal intervals in the middle of the top wall of the frame. Stabilizer plates are fixedly connected to adjacent sides of the two stabilizer frames. The adjacent sides of the two stabilizer plates are fixedly connected to the motor.

[0016] As a further description of the above technical solution:

[0017] The frame has two sliding grooves on the left and right sides of the inner middle part, and the upper sides of the two sliding grooves are slidably connected to cover plates.

[0018] As a further description of the above technical solution:

[0019] X-shaped brackets are installed at both the front and rear ends of the frame, and screws are threaded onto the four corners of the two X-shaped brackets.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the motor drives the spiral blade to rotate inside the outer tube through the rotating rod, which propels the ultrafine powder material in a spiral. At this time, the air pump extracts the gas inside the outer tube through the connecting pipe. After some of the ultrafine powder material squeezed out by the spiral blade passes through the inner layer of the double-layer filter, it will be intercepted again by the outer layer, thereby achieving the effect of avoiding blockage of the connecting pipe.

[0022] 2. In this utility model, the rotating adjustment ring drives the turntable to rotate inside the outer tube through the connecting rod. When the turntable rotates, it drives the corresponding adjustment block to slide inside the outer tube through the guide groove. At this time, the slide groove guides the sliding trajectory of the adjustment block, thereby achieving the effect of controlling the speed of the online degassing device of the ultrafine powder silo.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 2 and Figure 3This utility model provides an embodiment of an online degassing device for an ultrafine powder silo, comprising a frame 1, a motor 3 fixedly connected to the top of the frame 1, a rotating rod 4 fixedly connected to the output end of the motor 3, a spiral blade 5 fixedly connected to the lower middle part of the outer wall of the rotating rod 4, the motor 3 driving the spiral blade 5 to rotate through the rotating rod 4, an outer tube 6 fixedly connected to the middle inner side of the frame 1, a double-layer filter screen 7 fixedly connected to the inner side of the outer tube 6, a connecting pipe 8 connected to the right side of the outer tube 6, the double-layer filter screen 7 being fixed inside the outer tube 6 to prevent the connecting pipe 8 from being blocked, and the connecting pipe 8... The end of the pipe is connected to an air pump 9, which draws air from the outer pipe 6 through a connecting pipe 8. The bottom of the outer pipe 6 is equipped with a discharge rate adjustment mechanism 2, which is used to adjust the discharge rate of the outer pipe 6. The bottom of the outer wall of the air pump 9 is fixedly connected to a mounting bracket 10. Each of the four corners of the mounting bracket 10 is threaded with a screw 11, which is used to fix the mounting bracket 10. The left end of the connecting pipe 8 is fixedly connected to a fixing ring 12, and the inner wall of the fixing ring 12 is fixedly connected to an intercepting net 13, which is used to fix the intercepting net 13.

[0032] Specifically, the motor 3 drives the rotating rod 4 to rotate, and the rotating rod 4 drives the spiral blade 5 to rotate inside the outer tube 6, which propels the ultrafine powder material in a spiral motion. At this time, the air pump 9 extracts the gas from the outer tube 6 through the connecting pipe 8, creating a negative pressure inside the outer tube 6. The inner wall of the outer tube 6 and the spiral blade 5 are separated by a double-layer filter screen 7. Some of the ultrafine powder material squeezed out by the spiral blade 5 is intercepted again by the outer layer after passing through the inner layer of the double-layer filter screen 7. The mounting bracket 10 is fixed by screws 11 to provide support for the air pump 9, and the intercepting net 13 installed by the fixing ring 12 can further protect the connecting pipe 8.

[0033] Reference Figure 4 and Figure 5 The shipment volume adjustment mechanism 2 includes an adjustment block 201. The upper and lower ends of multiple adjustment blocks 201 are slidably connected to the upper end of the inner tube 6. The lower end of the inner tube 6 is rotatably connected to a turntable 202. The inner top wall of the outer tube 6 is provided with a sliding groove 203, which is used to guide the adjustment block 201 to slide. The top of the outer wall of the turntable 202 is provided with multiple guide grooves 204 at equal intervals. The bottom of the turntable 202 is fixedly connected with connecting rods 205 at equal intervals. The bottom of each of the multiple connecting rods 205 is fixedly connected with an adjustment ring 206. The adjustment ring 206 drives the turntable 202 to rotate through the connecting rods 205. The outer wall of the adjustment ring 206 is fixedly connected with a rubber sleeve 14. The outer wall of the rubber sleeve 14 is provided with anti-slip texture 15, which is used to increase the friction of the rubber sleeve 14.

[0034] Specifically, rotating the adjusting ring 206 causes multiple connecting rods 205 to rotate in a regular pattern. The rotation of the multiple connecting rods 205 causes the turntable 202 to rotate inside the outer tube 6. When the turntable 202 rotates inside the outer tube 6, it causes the corresponding adjusting block 201 to slide inside the outer tube 6 through multiple guide grooves 204. At this time, the slide groove 203 guides the sliding trajectory of the adjusting block 201. The rubber sleeve 14 fixed outside the adjusting ring 206 improves its anti-slip performance through the anti-slip texture 15.

[0035] Reference Figure 1 and Figure 2 A stabilizing frame 16 is fixedly connected at equal intervals in the middle of the top wall of the frame 1. A stabilizing plate 17 is fixedly connected to the adjacent side of the two stabilizing frames 16. The stabilizing plate 17 is used to fix the stabilizing frame 16. The adjacent side of the two stabilizing plates 17 is fixedly connected to the motor 3. A sliding groove 18 is opened on the left and right sides of the middle inner side of the frame 1. A cover plate 19 is slidably connected to the upper side of the two sliding grooves 18. The cover plate 19 slides through the sliding groove 18. X-shaped frames 20 are installed at the front and rear ends of the frame 1. Screws 21 are threaded at the four corners of the two X-shaped frames 20. Screws 21 are used to fix the X-shaped frames 20.

[0036] Specifically, the stabilizer 16, together with the stabilizer plate 17, provides support for the motor 3. The cover plate 19, which slides through the second slide groove 18, can prevent dust from drifting out from above the outer tube 6. The X-shaped frame 20, which is fixed by the second screw 21, can improve the stability of the frame 1.

[0037] Working principle: When using the online degassing device of the ultrafine powder silo to degas the ultrafine powder, the motor 3 fixed on the frame 1 is started first. The power provided by the motor 3 drives the rotating rod 4 to rotate. While the rotating rod 4 is rotating, the spiral blade 5 will rotate in the outer tube 6, which will push the ultrafine powder material in a spiral. At this time, the air pump 9 will extract the gas in the outer tube 6 through the connecting pipe 8, forming a negative pressure in the outer tube 6. The inner wall of the outer tube 6 and the spiral blade 5 are isolated by a double-layer filter screen 7. Some of the ultrafine powder material squeezed out by the spiral blade 5 will be intercepted again by the outer layer after passing through the inner layer of the double-layer filter screen 7, thereby achieving the effect of avoiding the blockage of the connecting pipe 8.

[0038] When using the online degassing device of the ultrafine powder silo to degas the ultrafine powder, the adjustment ring 206 is rotated to drive multiple connecting rods 205 to rotate in a regular pattern. The rotation of the multiple connecting rods 205 drives the turntable 202 to rotate inside the outer tube 6. When the turntable 202 rotates inside the outer tube 6, it drives the corresponding adjusting block 201 to slide inside the outer tube 6 through multiple guide grooves 204. At this time, the slide groove 203 guides the sliding trajectory of the adjusting block 201, thereby achieving the effect of controlling the output speed of the online degassing device of the ultrafine powder silo.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
