Description

Technical Field

[0001] The utility model relates to the technical field of silo anti-blocking, in particular to an automatic frequency modulation anti-blocking device for silo. Background Art

[0002] After investigation, it is found that more than 90% of the blockages in the raw coal bunker occur within 1 to 2 meters above the outlet of the lower raw coal bunker. The main reason for the blockage in this section is that when the bunker is unloaded, the materials in the conical bunker expand horizontally and compress vertically, and the stress is in a passive plastic state; as the size of the bunker outlet decreases, the pressure increases, the friction between the coal particles and between the coal and the cylinder wall increases, the coal particles agglomerate, and the characteristic size increases significantly, so the blockage mainly occurs in this section.

[0003] The existing coal silo is too large in overall volume, so it is troublesome to take out the silo at the entrance. At present, a hole is often opened at the bottom of the silo to install a guide device so that the silo in the silo can slide naturally under the influence of gravity. Due to the friction between the silos, coal particles agglomerate and the silo can easily become stuck. Therefore, the staff needs to frequently clear the silo outlets, which is time-consuming and labor-intensive.

[0004] Therefore, we propose a silo automatic frequency regulation and anti-blocking device. Summary of the invention

The dredging component is used to vibrate the silo inside the silo body, and the dredging component can prevent the silo inside the silo body from being blocked when taking out the silo, and the closing component is installed at the lower part of the silo body, and the closing component is used to seal the silo inside the silo body.

[0007] Preferably, two guide bolts are fixedly installed above the outer wall of the silo body, and the two guide bolts respectively penetrate the inner wall of the silo body and are clamped on the broken arch plate.

[0008] Preferably, an isolation sealing frame is fixedly connected to the upper surface of the silo body, and the isolation sealing frame completely covers the guide bolts.

[0009] Preferably, a push rod is fixedly connected between the mutually adjacent sides of the two arch breaking plates, a material discharge circular tube is placed inside the silo body, a fixed block is fixedly connected to the outer surface of the material discharge circular tube, and the bottom surface of the fixed block is in contact with the two push rods.

[0010] Preferably, a mounting frame is fixedly mounted on the bottom surface of the isolation sealing frame, the mounting frame is clamped with a material discharge circular tube, and a conical block is fixedly connected to the upper surface of the material discharge circular tube.

[0011] Preferably, a first spring is fixedly mounted between the bottom surface of the mounting frame and the upper surface of the fixing block, and the first spring is sleeved with the material discharge circular tube.

[0012] Preferably, the closing assembly comprises a sealing plate, which is placed below the silo body; the bottom surface of the silo body is fixedly connected to a limiting rod, the limiting rod is snap-fitted to the sealing plate, the upper surface of the sealing plate is fixedly connected to a sealing block, the size of the sealing block is adapted to the size of the outlet of the bottom surface of the silo body, the bottom surface of the limiting rod is fixedly connected to a fixing disk, the upper surface of the fixing disk is fixedly connected to a second spring, the second spring is socketed with the limiting rod, and the bottom surface of the sealing plate is in contact with the top end of the second spring.

[0013] Preferably, the sealing block is hemispherical in shape, and the cross-sectional shape of the silo body outlet is circular.

[0014] The utility model has at least the following beneficial effects:

[0015] 1. When it is necessary to discharge the material silo inside the silo body, the discharge port of the silo body is prone to blockage. At this time, first turn on the power switch electrically connected to the body of the excitation wave device. At this time, the output end of the excitation wave device body starts to work, which will drive the arch breaking plate to reciprocate. At this time, the arch breaking plate will move relatively stably under the influence of the elastic force of the circular rubber spring and the T-shaped rubber spring. The guide bolt is provided to provide a guiding effect for the movement of the arch breaking plate, so that the arch breaking plate can be more stable when reciprocating. When the arch breaking plate reciprocates, the two push rods will move synchronously at this time. At this time, the push rod will lift the fixed block. When the push rod moves downward, the fixed block will drop under the influence of the elastic force of the first spring, and then the mounting frame will guide the material sludge round tube, so that the material sludge round tube can move up and down synchronously, so that the material sludge round tube can be dredged. At this time, through the coordinated setting of the arch breaking plate and the material sludge round tube, the discharge of the silo at the discharge port of the silo body can be smoother.

[0016] By setting up the dredging component, the silo can be effectively prevented from being blocked at the outlet and inside of the silo body, reducing the problem that a guide device is installed at the bottom of the silo to allow the silo to slide naturally under the influence of gravity. Due to the friction between the silos, coal particles agglomerate, and the silo is easily stuck. Therefore, the staff needs to frequently dredge the outlets of multiple silos, which is time-consuming and laborious.

[0017] The main body of the excitation wave device uses a vibration motor as the excitation source. Two sets of excitation wave devices are symmetrically installed at the bottom of the silo body. The excitation wave device uses the centrifugal force generated by the eccentric block of the vibration motor during high-speed rotation to vibrate the broken arch plate inside the silo body, thereby activating the material and achieving the purpose of dredging and unloading.

[0018] 2. When the silo body needs to be closed after the material in the silo is discharged, you only need to turn the handle of the sealing plate. At this time, the outer wall of the bottom surface of the silo body will first contact the sealing block. Because the sealing block is spherical, the sealing block is squeezed by the outer wall of the bottom surface of the silo body, which will cause the sealing plate to drop as a whole. At this time, the guiding effect of the limit rod can make the sealing plate drop more stably. When the sealing block is turned to the bottom of the silo body, it will be affected by the elastic force of the second spring, which will cause the sealing block to close the discharge port of the silo body.

[0019] By setting up a closing component, when the silo needs to be opened or closed, the limiting rod and the sealing rod and other components can be cooperated to make the sealing block close the discharge port of the silo body, thereby achieving a more stable effect when opening or closing the discharge port of the silo body.

[0027] Embodiment 1

[0028] A silo automatic frequency modulation anti-blocking device comprises a silo body 3, a dredging component 1, the dredging component 1 is installed inside the silo body 3, the dredging component 1 comprises two arch-breaking plates 4, the two arch-breaking plates 4 are both installed inside the silo body 3, a plurality of circular rubber springs 5 ​​are installed between the mutually distant sides of the two arch-breaking plates 4 and the inner wall of the silo body 3, two exciting wave-generating device bodies 7 are fixedly installed on the outer wall of the silo body 3, the output ends of the two exciting wave-generating device bodies 7 are respectively fixedly connected with the corresponding arch-breaking plates 4, and the two exciting wave-generating device bodies 7 are respectively fixedly connected with the corresponding arch-breaking plates 4. The output ends are all snap-connected with the outer surface of the silo body 3, and a group of T-shaped rubber springs 6 are fixedly installed between the sides of the two arch-breaking plates 4 that are away from each other. Each group of T-shaped rubber springs 6 is socketed with the output end of the corresponding excitation wave device body 7. The dredging component 1 is used to vibrate the silo inside the silo body 3. The dredging component 1 can prevent the silo inside the silo body 3 from being blocked when taking out the silo. The closing component 2 is installed at the lower part of the silo body 3. The closing component 2 is used to seal the silo inside the silo body 3.

[0029] Two guide bolts 15 are fixedly installed above the outer wall of the silo body 3. The two guide bolts 15 respectively penetrate the inner wall of the silo body 3 and are clamped on the arch breaking plate 4, which can provide guidance and support for the movement of the arch breaking plate 4.

[0030] An isolation sealing frame 8 is fixedly connected to the upper surface of the silo body 3 , and the isolation sealing frame 8 completely covers the guide bolt 15 , thereby preventing the silo from being stuck between the guide bolt 15 and the broken arch plate 4 when the silo body 3 is loaded with silo.

[0031] A push rod 14 is fixedly connected between the surfaces of the two arch-breaking plates 4 that are close to each other, a material-discharging circular tube 10 is placed inside the silo body 3, and a fixed block 13 is fixedly connected to the outer surface of the material-discharging circular tube 10. The bottom surface of the fixed block 13 is in contact with the two push rods 14, and the fixed block 13 can be driven to reciprocate and lift and vibrate when the push rod 14 is reciprocatingly vibrating.

[0032] The bottom surface of the isolation sealing frame 8 is fixedly mounted with a mounting frame 11, which is clamped with the material discharging circular tube 10. The upper surface of the material discharging circular tube 10 is fixedly connected with a conical block 9, which can guide the up and down lifting and vibration of the material discharging circular tube 10.

[0033] A first spring 12 is fixedly installed between the bottom surface of the mounting frame 11 and the upper surface of the fixing block 13. The first spring 12 is sleeved with the material dispersing circular tube 10, which can provide power for the material dispersing circular tube 10 when it is descending, and further make the material dispersing circular tube 10 more stable when it is in a vibrating state.

[0034] When it is necessary to discharge the material silo inside the silo body 3, the discharge port of the silo body 3 is prone to blockage. At this time, first turn on the power switch electrically connected to the excitation wave device body 7. At this time, the output end of the excitation wave device body 7 starts to work, which will drive the arch breaking plate 4 to reciprocate. At this time, the arch breaking plate 4 will move stably under the influence of the elastic force of the circular rubber spring 5 and the T-shaped rubber spring 6. The guide bolt 15 is provided to provide a guide for the movement of the arch breaking plate 4, so that the arch breaking plate 4 can be more stable when performing reciprocating vibration. When the plate 4 vibrates back and forth, the two push rods 14 will move synchronously, and the push rods 14 will lift the fixed block 13. When the push rods 14 move downward, the fixed block 13 will drop under the influence of the elastic force of the first spring 12, and then the mounting frame 11 will guide the material discharging circular tube 10, so that the material discharging circular tube 10 can move up and down synchronously, so that the material discharging circular tube 10 can be unblocked. At this time, through the coordinated setting of the arch breaking plate 4 and the material discharging circular tube 10, the material discharging of the material silo at the material discharging port of the silo body 3 can be made smoother.

[0035] By setting up the unblocking component 1, the silo can be effectively prevented from being blocked at the outlet and inside of the silo body 3, which solves the problem that a hole is opened at the bottom of the silo to install a guide device so that the silo in the silo can slide naturally under the influence of gravity. Due to the friction between the silos, the silos can easily become stuck, so the staff needs to frequently unblock the outlets of multiple silos, which is time-consuming and labor-intensive.

[0036] Embodiment 2

[0037] The closing assembly 2 includes a sealing plate 16, which is placed below the silo body 3. The bottom surface of the silo body 3 is fixedly connected to a limiting rod 17, which is snap-fitted to the sealing plate 16. The upper surface of the sealing plate 16 is fixedly connected to a sealing block 20, and the size of the sealing block 20 is adapted to the size of the outlet of the bottom surface of the silo body 3. The bottom surface of the limiting rod 17 is fixedly connected to a fixing disk 19, and the upper surface of the fixing disk 19 is fixedly connected to a second spring 18, which is socketed with the limiting rod 17. The bottom surface of the sealing plate 16 is in contact with the top of the second spring 18.

[0038] The sealing block 20 is hemispherical in shape, and the cross-sectional shape of the outlet of the silo body 3 is circular, so that the sealing block 20 has a better sealing effect when sealing the outlet of the silo body 3 .

[0039] When the silo body 3 needs to be closed after the material silo inside is discharged, it is only necessary to turn the handle of the sealing plate 16. At this time, the outer wall of the bottom surface of the silo body 3 will first contact the sealing block 20. Because the sealing block 20 is spherical, the sealing block 20 is squeezed by the outer wall of the bottom surface of the silo body 3, which will cause the sealing plate 16 to drop as a whole. At this time, the guiding effect of the limiting rod 17 can make the sealing plate 16 drop more stably. When the sealing block 20 rotates to the bottom of the silo body 3, it is affected by the elastic force of the second spring 18, which will cause the sealing block 20 to close the discharge port of the silo body 3.

[0040] By providing the closing component 2 , it is possible to facilitate opening or closing the discharge port of the silo body 3 .
