Abstract
Description
Technical Field
[0001] This invention relates to the field of silo anti-clogging technology, specifically to a chain-type ring wall anti-clogging machine. Background Technology
[0002] To improve production efficiency, a preparation hopper is installed above the mixer so that there is always a batch of mixed materials waiting to be mixed, which can increase production efficiency by 30%. This is how the advantages of a high-efficiency mixer are demonstrated. A conical hopper is usually installed at the bottom of the hopper for material discharge.
[0003] Currently, the outlet at the bottom of the silo is mostly a hopper structure. When bulk materials fall into the hopper and are conveyed outward, most of the materials in the middle fall freely first, while the material flow on the side wall of the hopper is slow or even stops. This often leads to phenomena such as material blockage, material bridging, center flow, arching, and wall hanging in the hopper, which prevents the hopper from unloading normally and seriously affects the normal operation of the overall production system. Summary of the Invention
[0004] The purpose of this invention is to provide a chain-type ring wall anti-clogging machine to solve the above problems.
[0005] To achieve the above objectives, the present invention specifically adopts the following technical solution:
[0006] A chain-type ring wall anti-clogging machine includes a hopper. An inner ring is fixedly installed at the discharge port at the bottom of the hopper, and an outer ring is rotatably installed on the outer side of the inner ring. Multiple sets of connecting buckles are arranged in a ring on the inner side of the outer ring. Multiple sets of iron chains are arranged in a ring inside the hopper. The bottom end of the iron chain is connected to the connecting buckle, and the top end of the iron chain is connected to the inner wall above the hopper. A drive assembly is installed on the outer side of the discharge port of the hopper, which can drive the outer ring to rotate in both directions.
[0007] Furthermore, the drive assembly includes a transmission box welded to the outside of the hopper outlet. Two sets of transmission boxes are provided, and the two sets of transmission boxes are symmetrically arranged on both sides of the hopper. A drive motor is fixedly installed at the bottom of the transmission box, and a drive wheel is fixedly installed at the output end of the drive motor. An outer gear tooth is provided on the outer side of the outer ring, and the drive wheel meshes with the outer gear tooth.
[0008] Furthermore, a limit switch is fixedly installed on the outside of the transmission box, and two sets of contact rods are provided on the outside of the outer ring. When the contact rods approach the limit switch, the drive motor on the same side as the limit switch is de-energized, and the drive motor on the other side is energized.
[0009] Furthermore, the hopper has multiple sets of connecting windows arranged in a ring above it. An upper fixing ring is welded to the outside of the hopper and is positioned above the connecting windows. Multiple sets of levers are fixedly installed at the bottom of the upper fixing ring. The bottom of each lever has a triangular design. An outer sliding ring is provided on the outside of the hopper. An outer ring sleeve is rotatably installed inside the outer sliding ring and fits onto the outside of the connecting windows. A swing rod is hinged inside the outer ring sleeve. A top spring is provided between the swing rod and the outer ring sleeve. The top of the chain is connected to the swing rod. A connecting component is provided on the outside of the outer ring sleeve, which connects the outer ring sleeve to the outer ring.
[0010] Furthermore, the connecting assembly includes a connecting rod fixedly installed on the outer ring sleeve. A connecting box is provided at the bottom of the connecting rod. An electromagnet is fixedly installed inside the connecting box. A pin is slidably connected inside the connecting box. An iron plate is provided at the bottom end of the pin. A top spring is provided between the iron plate and the electromagnet. An insertion hole is opened at the bottom of the outer ring, and the pin can be inserted into the insertion hole.
[0011] Furthermore, the outer sliding ring consists of an upper ring and a lower ring. The upper ring is located above the connecting window and is fixedly installed on the hopper by bolts. The lower ring is located below the connecting window and is welded to the hopper.
[0012] Furthermore, reinforcing ribs are provided between the upper fixing ring and the hopper.
[0013] Furthermore, a rolling element and a seal are provided between the inner ring and the outer ring.
[0014] The beneficial effects of this invention are as follows:
[0015] 1. This invention employs a chain-type ring wall anti-clogging method, which is installed within a certain range above the hopper outlet. Through the repeated rotation and cutting of the ring chain within the hopper, the normal flow of material in the hopper is maintained, preventing problems such as material blockage, bridging, central flow, arching, wall adhesion, and silo sticking. This completely solves the problem of difficult material discharge from bulk material hoppers. It is widely applicable to industries such as power, metallurgy, mining, chemical, grain, cement, environmental protection, and pharmaceuticals.

[0016] 2. This invention employs a chain-type ring wall anti-clogging method, which can completely cover the hopper wall, eliminating dead corners and eradicating problems such as material bridging and blockage. The chain-type ring wall anti-clogging method has strong adaptability to materials, and factors such as the type, moisture content, particle size, temperature, and viscosity of bulk materials in the hopper no longer affect the stability of unloading, ensuring the stability of the overall production system. The equipment itself has a simple structure, and maintenance is simple and safe. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0027] Example 1, as Figures 1-8 As shown, a chain-type ring wall anti-clogging machine includes a hopper 1. An inner ring 2 is fixedly installed at the discharge port at the bottom of the hopper 1. An outer ring 3 is rotatably installed on the outer side of the inner ring 2. Multiple sets of connecting buckles 31 are arranged in a ring on the inner side of the outer ring 3. Multiple sets of iron chains 4 are arranged in a ring inside the hopper 1. The bottom end of the iron chain 4 is connected to the connecting buckle 31, and the top end of the iron chain 4 is connected to the inner wall above the hopper 1. A drive assembly is installed on the outer side of the discharge port of the hopper 1. The drive assembly can drive the outer ring 3 to rotate in both directions.
[0028] By controlling the operation of the drive component, the drive component drives the outer ring 3 to rotate in both directions. The outer ring 3 drives the iron chain 4 to rotate and cut repeatedly inside the hopper 1, maintaining the normal flow of materials in the hopper 1 and preventing problems such as material blockage, bridging, central flow, arching, wall hanging, and sticking in the hopper 1. This completely solves the problem of difficult discharge of bulk materials from the hopper 1. The equipment itself has a simple structure, and the inspection and maintenance work is simple and safe.
[0029] Example 2, based on the above examples, further includes a drive assembly comprising a transmission box 5 welded to the outside of the discharge port of the hopper 1. Two sets of transmission boxes 5 are provided, and the two sets of transmission boxes 5 are symmetrically arranged on both sides of the hopper 1. A drive motor 51 is fixedly installed at the bottom of the transmission box 5, and a drive wheel 52 is fixedly installed at the output end of the drive motor 51. An outer gear tooth is provided on the outer side of the outer ring 3, and the drive wheel 52 meshes with the outer gear tooth.
[0030] By controlling the left drive motor 51 to be energized, the drive motor 51 drives the drive wheel 52 to rotate. The drive wheel 52 drives the outer ring 3 to rotate counterclockwise through the outer gear teeth. By controlling the right drive motor 51 to be energized, the drive motor 51 drives the drive wheel 52 to rotate. The drive wheel 52 drives the outer ring 3 to rotate clockwise through the outer gear teeth. In this embodiment, the control method of the drive motor 51 is not limited. It can be controlled by limit switches, timing, etc.
[0031] In the third embodiment, based on the above embodiments, a limit switch 53 is fixedly installed on the outside of the transmission box 5, and two sets of contact rods 32 are provided on the outside of the outer ring 3. When the contact rod 32 approaches the limit switch 53, the drive motor 51 on the same side as the limit switch 53 is de-energized, and the drive motor 51 on the other side is energized. In this embodiment, the limit switch 53 is used for control.
[0032] Example 4, based on the above examples, further includes: a plurality of connecting windows 11 are circumferentially opened above the hopper 1; an upper fixing ring 12 is welded to the outside of the hopper 1; the upper fixing ring 12 is positioned above the connecting windows 11; a plurality of levers 13 are fixedly installed at the bottom of the upper fixing ring 12; the bottom end of the levers 13 is triangularly designed; an outer sliding ring 14 is provided on the outside of the hopper 1; an outer ring sleeve 6 is rotatably installed inside the outer sliding ring 14; the outer ring sleeve 6 is fitted onto the outside of the connecting windows 11; a swing rod 61 is hinged inside the outer ring sleeve 6; a top spring 62 is provided between the swing rod 61 and the outer ring sleeve 6; the top end of the iron chain 4 is connected to the swing rod 61; a connecting component is provided on the outside of the outer ring sleeve 6; the connecting component can connect the outer ring sleeve 6 and the outer ring 3 together.
[0033] This embodiment provides a different structure compared to Embodiment 1. By connecting the top end of the iron chain 4 to the swing arm 61, when only the outer ring 3 rotates, the swing arm 61 is located between the two sets of levers 13. The two sets of levers 13 restrict the rotation of the outer ring sleeve 6 through the swing arm 61. When the hopper 1 is severely blocked, the rigid connection method in Embodiment 1 is prone to causing the equipment to jam. However, with the setting of this embodiment, when the hopper 1 is severely blocked, the levers 13 will push the end of the swing arm 61 located outside the outer ring sleeve 6 to swing downward. At this time, the outer ring sleeve 6 can rotate a certain angle, so that the top end of the iron chain 4 can also rotate, thereby preventing the equipment from jamming and making the operation more stable.
[0034] Meanwhile, the equipment in this example is also suitable for bulk materials with high humidity. For high-humidity bulk materials, simply cutting with the rotating chain 4 is insufficient for discharge; it only breaks up the material at the edges, leaving the material in the middle prone to sticking together, resulting in slow discharge speed and easy material contamination on the chain 4. Therefore, a connecting assembly is used to connect the outer ring 3 and the outer ring sleeve 6, allowing the outer ring 3 to rotate synchronously with the outer ring sleeve 6. The outer ring sleeve 6 drives the swing rod 61 to rotate relative to the dial block 13. Under the action of the inclined surface of the dial block 13, the end of the swing rod 61 located outside the outer ring sleeve 6 swings downwards, and the end located inside the outer ring sleeve 6 swings upwards. This process is relatively slow. When the swing rod 61... When the lever 13 is passed, the swing arm 61 quickly returns to its original position under the action of the top spring 62. The end of the swing arm 61 located inside the outer ring sleeve 6 swings downward rapidly, giving the chain 4 a disturbance force, causing the chain 4 to fluctuate towards the middle of the hopper 1. Since the bottom of the lever 13 is triangularly designed, the chain 4 fluctuates repeatedly when the outer ring 3 and the outer ring sleeve 6 reciprocate. The chain 4 as a whole will rotate relative to the material, which can completely disperse the material with high moisture content, ensuring a fast discharge speed. At the same time, since the chain 4 fluctuates and hits the inner wall of the hopper 1, it can not only prevent the material from sticking to the inner wall of the hopper 1, but also shake off the material stuck to it, resulting in a better discharge effect.
[0035] Example 5, based on the above examples, further includes a connecting component comprising a connecting rod 7 fixedly mounted on the outer ring sleeve 6, a connecting box at the bottom of the connecting rod 7, an electromagnet 71 fixedly mounted inside the connecting box, a pin 72 slidably connected inside the connecting box, an iron plate at the bottom end of the pin 72, a top spring 73 between the iron plate and the electromagnet 71, and an insertion hole 33 at the bottom of the outer ring 3, into which the pin 72 can be inserted.
[0036] By controlling the electromagnet 71 to be energized, the electromagnet 71 attracts the iron sheet, and the iron sheet drives the pin 72 to be inserted into the socket 33, thereby connecting the outer ring 3 and the outer ring sleeve 6 together, so that they can rotate synchronously. When the electromagnet 71 is de-energized, the top spring 73 pushes the pin 72 away from the socket 33, and the outer ring 3 rotates independently.
[0037] Example 6, based on the above examples, further includes an outer sliding ring 14 consisting of an upper ring and a lower ring. The upper ring is located above the connecting window 11 and is fixedly installed on the hopper 1 by bolts. The lower ring is located below the connecting window 11 and is welded to the hopper 1. This design facilitates the installation and disassembly of the outer ring sleeve 6.
[0038] Furthermore, reinforcing ribs are provided between the upper fixing ring 12 and the hopper 1 to improve the structural stability of the upper fixing ring 12.
[0039] Example 7, based on the above examples, further includes a rolling element and a seal between the inner ring 2 and the outer ring 3, resulting in a good sealing effect.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
