Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic conveying, and particularly relates to a cyclone pulse arch-breaking device. Background Technique

[0002] Pneumatic conveying silo pumps are often installed under hoppers (intermediate silos). For materials that are not very sticky and have a large bulk density, they can usually enter the conveying silo pump well by gravity. For materials that are light in weight, easy to adhere to the wall, and slightly larger in volume, when entering the conveying pump from the hopper, it is easy to form a compression arch, a wedge-shaped arch, or an adhesive arch. Therefore, an arch-breaking device is required.

[0003] In the prior art, the arch-breaking device often uses the method of vibrating the silo to prevent material stacking or uses an air cannon to disperse the stacked materials during discharging. However, the noise is relatively large when vibrating the silo, and powder may return during the blowing interval of the air cannon.

[0004] Based on this, the utility model designs a cyclone pulse arch-breaking device to solve the above problems. Content of the Utility Model

[0005] In view of the above-mentioned disadvantages of the prior art, the utility model provides a cyclone pulse arch-breaking device.

[0006] To achieve the above objectives, the utility model is realized through the following technical solutions:

[0007] A cyclone pulse arch-breaking device includes an air supply pipe;

[0008] The lower end of the air supply pipe is connected with an adjustable air-dispersing component for expanding the flying range of the gas in the air supply pipe and preventing powder return;

[0009] The outer side of the upper end of the adjustable air-dispersing component is connected with a limit guiding component for limiting and guiding the upper end of the adjustable air-dispersing component, and the outer end of the limit guiding component is connected to the inner wall of the air supply pipe;

[0010] The adjustable air-dispersing component includes an air-dispersing component and an adjusting component. The lower end of the air supply pipe is connected with the air-dispersing component, the upper end of the air-dispersing component is connected with the adjusting component, the outer side of the lower end of the adjusting component is connected to the inner wall of the air supply pipe, and the outer side of the upper end of the adjusting component is connected with the limit guiding component.

[0011] Furthermore, the air-dispersing component includes a plugging disc, a conical air-dispersing runner, a pneumatic runner, and a rotating shaft. The bottom of the air supply pipe is in contact connection with the plugging disc. The middle position of the top of the plugging disc is fixedly connected with a conical air-dispersing runner. The middle position of the top of the conical air-dispersing runner is fixedly connected with a pneumatic runner. The middle position of the top of the pneumatic runner is fixedly connected with a rotating shaft, and the rotating shaft is connected with the adjusting component.

[0012] Furthermore, the adjusting assembly includes a limit support plate, a support rod, a bearing, a nut and a spring. A notch is formed in the middle of the limit support plate. The rotating shaft passes through the notch in the middle of the limit support plate. Several groups of support rods are fixedly connected to the outer end of the limit support plate. One end of each support rod close to the inner wall of the air supply pipe is fixedly connected to the inner side wall of the air supply pipe. The upper end of the limit support plate passes through the bearing and is slidably connected to the inner rotating disc of the bearing. A nut is fixedly connected to the top of the inner rotating disc of the bearing. The upper end of the rotating shaft passes through the nut and is threadedly connected to the nut. A spring is fixedly connected between the outer rotating disc of the bearing and the limit support plate.

[0013] Furthermore, the spring is always in a compressed deformation state.

[0014] Furthermore, there is a gap between the rotating shaft and the inner wall of the notch in the middle of the limit support plate. The rotating shaft can slide up and down in the notch in the middle of the limit support plate, and the rotating shaft can also rotate in the notch in the middle of the limit support plate.

[0015] Furthermore, a limit guiding assembly is connected to the outer end of the bearing.

[0016] Furthermore, the limit guiding assembly includes a limit plate, a limit sliding groove and a limit sliding strip. Several groups of limit plates are fixedly connected to the outer end of the bearing. A limit sliding groove is formed at one end of each limit plate close to the air supply pipe. Several groups of limit sliding strips that are in sliding connection with and cooperate with the limit sliding grooves are fixedly connected to the inner wall of the air supply pipe. The limit sliding strips all pass through the limit sliding grooves.

[0017] The utility model has the following technical effects:

[0018] 1. When the air flow enters the air supply pipe, the air pressure inside the air supply pipe increases, causing the gas to squeeze the sealing disc downward. When the sealing disc moves downward, it drives the conical air-dispersing runner, pneumatic runner, and rotating shaft downward. The rotating shaft, in turn, drives the bearing downward through the nut. At this time, the bearing and the limit support plate squeeze the spring, causing the spring to undergo compressive deformation. At this time, the air flow flies out from the gap between the sealing disc and the air supply pipe. The air flow blows the impellers of the pneumatic runner and the conical air-dispersing runner, causing the pneumatic runner and the conical air-dispersing runner to rotate under the limit support of the rotating shaft and the bearing. At this time, the air flow is driven by the impeller of the conical air-dispersing runner and scatters out in all directions, increasing the area where the air flow flies out. Thus, the air flow can clean and break the arch on the inner wall of the hopper. When the air pressure inside the air supply pipe decreases, under the action of the spring restoring force, the sealing disc moves upward and reseals the lower opening of the air supply pipe, achieving the automatic opening and closing of the lower opening of the air supply pipe and being able to close the lower opening of the air supply pipe in a timely manner, effectively preventing the situation of powder backflow. At this time, since the bearing moves up and down, it drives the limit plate to move up and down under the limit of the limit sliding groove and the limit sliding strip, ensuring the stability of the bearing's lifting and preventing the outer ring of the bearing from rotating. When it is necessary to adjust the starting threshold of the arch-breaking device, rotate the nut. The nut drives the bearing to move up and down. When the bearing moves downward, the bearing squeezes the spring, causing the spring to undergo a greater degree of compressive deformation. Thus, the spring's upward thrust on the bearing is greater, and further, a greater air pressure requirement is needed to push the limit support plate downward, thereby increasing the starting threshold of the arch-breaking device. Conversely, rotating the nut upward can reduce the starting threshold of the arch-breaking device, greatly improving the applicability of the arch-breaking device. And when it is necessary to clean the inside of the air supply pipe or repair the components inside the air supply pipe, rotate the nut and remove it. At this time, the sealing disc, conical air-dispersing runner, pneumatic runner, and rotating shaft can be taken out together, realizing the simple disassembly of the device and reducing the repair cost.

[0027] The present utility model will be further described below with reference to the embodiments.

[0028] Embodiment

[0029] Please refer to the attached specification Figures 1-5 , a swirl pulse arch breaking device, comprising an air supply pipe 1;

[0030] The lower end of the air supply pipe 1 is connected with an adjustable air dispersion assembly 2 for automatically opening and discharging the materials in a dispersed manner;

[0031] The outer side of the upper end of the adjustable air dispersion assembly 2 is connected with a limit guiding assembly 3 for limiting and guiding the upper end of the adjustable air dispersion assembly 2, and the outer end of the limit guiding assembly 3 is connected to the inner wall of the air supply pipe 1;

[0032] The adjustable air dispersion assembly 2 includes an air dispersion assembly 21 and an adjusting assembly 22. The lower end of the air supply pipe 1 is connected with the air dispersion assembly 21, the upper end of the air dispersion assembly 21 is connected with the adjusting assembly 22, the outer side of the lower end of the adjusting assembly 22 is connected to the inner wall of the air supply pipe 1, and the outer side of the upper end of the adjusting assembly 22 is connected with the limit guiding assembly 3;

[0033] The air-dispersing assembly 21 includes a plugging disc 211, a conical air-dispersing runner 212, a pneumatic runner 213 and a rotating shaft 214. The bottom of the air supply pipe 1 is in contact connection with the plugging disc 211. The middle position of the top of the plugging disc 211 is fixedly connected with the conical air-dispersing runner 212. The middle position of the top of the conical air-dispersing runner 212 is fixedly connected with the pneumatic runner 213. The middle position of the top of the pneumatic runner 213 is fixedly connected with the rotating shaft 214. The rotating shaft 214 is connected with the adjusting assembly 22;

[0034] The adjusting assembly 22 includes a limit support plate 221, a support rod 222, a bearing 223, a nut 224 and a spring 225. A notch is formed in the middle of the limit support plate 221. The rotating shaft 214 passes through the notch in the middle of the limit support plate 221. Several groups of support rods 222 are fixedly connected to the outer end of the limit support plate 221. One ends of the support rods 222 close to the inner wall of the air supply pipe 1 are fixedly connected to the inner side wall of the air supply pipe 1. The upper end of the limit support plate 221 passes through the bearing 223 and is in sliding connection with the inner turntable of the bearing 223. The top of the inner turntable of the bearing 223 is fixedly connected with the nut 224. The upper end of the rotating shaft 214 passes through the nut 224 and is in threaded connection with the nut 224. A spring 225 is fixedly connected between the outer turntable of the bearing 223 and the limit support plate 221. The outer end of the bearing 223 is connected with a limit guiding assembly 3;

[0035] The spring 225 is always in a compressed deformation state;

[0036] There is a gap between the rotating shaft 214 and the inner wall of the notch in the middle of the limit support plate 221. The rotating shaft 214 can slide up and down in the notch in the middle of the limit support plate 221, and the rotating shaft 214 can also rotate in the notch in the middle of the limit support plate 221;

[0037] The limit guiding assembly 3 includes a limit plate 31, a limit sliding groove 32 and a limit sliding strip 33. Several groups of limit plates 31 are fixedly connected to the outer end of the bearing 223. One ends of the limit plates 31 close to the air supply pipe 1 are respectively provided with limit sliding grooves 32. Several groups of limit sliding strips 33 which are in matching limit sliding connection with the limit sliding grooves 32 are fixedly connected to the inner wall of the air supply pipe 1. The limit sliding strips 33 all pass through the limit sliding grooves 32;

[0038] When the air flow enters the air supply pipe 1, the air pressure inside the air supply pipe 1 increases, causing the gas to squeeze the sealing disc 211 downward. When the sealing disc 211 moves downward, it drives the conical air-dispersing runner 212, the pneumatic runner 213, and the rotating shaft 214 downward. The rotating shaft 214 drives the bearing 223 downward through the nut 224. At this time, the bearing 223 and the limit support plate 221 squeeze the spring 225, causing the spring 225 to undergo compressive deformation. At this time, the air flow flies out from the gap between the sealing disc 211 and the air supply pipe 1. At this time, the air flow blows the impellers of the pneumatic runner 213 and the conical air-dispersing runner 212, causing the pneumatic runner 213 and the conical air-dispersing runner 212 to rotate under the limit support of the rotating shaft 214 and the bearing 223. At this time, the air flow is driven by the impeller of the conical air-dispersing runner 212 and scatters around, increasing the area where the air flow flies out, so that the air flow can clean and break the arch on the inner wall of the hopper. When the air pressure in the air supply pipe 1 decreases, under the action of the restoring force of the spring 225, the sealing disc 211 moves upward and re-seals the lower opening of the air supply pipe 1, realizing the automatic opening and closing of the lower opening of the air supply pipe 1, and being able to close the lower opening of the air supply pipe 1 in the first place, effectively preventing the situation of powder backflow. At this time, since the bearing 223 moves up and down, it drives the limit plate 31 to move up and down under the limit of the limit chute 32 and the limit slide bar 33, ensuring the stability of the lifting of the bearing 223 and preventing the outer ring of the bearing 223 from rotating. When it is necessary to adjust the starting threshold of the arch-breaking device, rotate the nut 224. The nut 224 drives the bearing 223 to move up and down. When the bearing 223 moves downward, the bearing 223 squeezes the spring 225, causing the spring 225 to be compressed to a greater extent, so that the spring 225 exerts a greater upward thrust on the bearing 223, and further making the air pressure required to push the limit support plate 221 downward greater, thereby increasing the starting threshold of the arch-breaking device. On the contrary, rotating the nut 224 upward can reduce the starting threshold of the arch-breaking device, greatly improving the applicability of the arch-breaking device. And when it is necessary to clean the inside of the air supply pipe 1 or repair the components inside the air supply pipe 1, rotate the nut 224 and remove the nut 224. At this time, the sealing disc 211, the conical air-dispersing runner 212, the pneumatic runner 213, and the rotating shaft 214 can be taken out together, realizing the simple disassembly of the device and reducing the repair cost.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
