Description

Technical Field

[0001] This application relates to the technical field of powder silo unblocking, and in particular to an anti-blockage powder silo unblocking device. Background Technology

[0002] An anti-clogging powder storage facility is a specially designed warehouse for storing powdered materials. Its focus is on implementing a series of measures to prevent powder from clogging during storage, ensuring the normal storage, flow, and retrieval of the powder. Different types of powders are rationally planned for storage based on their characteristics, particle size, and flowability. Powders prone to clogging are stored separately from other powders, and targeted anti-clogging measures are implemented. Simultaneously, materials are managed according to the first-in, first-out (FIFO) principle to avoid prolonged powder accumulation that could lead to clogging.

[0003] Regarding the aforementioned technologies, the inventors have discovered the following drawbacks: when the existing powder chamber is being cleared, the internal powder can cause the clearing to be incomplete, and the clearing end is easily blocked by powder, which can easily cause friction between the powder particles, making it highly susceptible to the influence of the working environment.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model, by setting up components such as an air flow aid, pipes and plug-in cylinders, inserts the plug-in cylinder into the interior of the powder silo. The strong airflow of the suddenly ejected compressed gas directly rushes into the blockage fault area of ​​the stored bulk material. The sudden release of the expansion shock wave overcomes the static friction of the material, allowing the powder in the container to resume flow, thus making the device adaptable to more working environments.

[0015] 2. This utility model uses two sets of identical fitting sleeves and other components to interlock, facilitating the replacement of the lower insertion cylinder. This prevents damage to components during unblocking, which could hinder the unblocking process. It also increases the natural flow of powder, reduces the possibility of accumulation and blockage, and allows the powder to slide smoothly under its own weight. This keeps the powder loose during unloading, preventing it from clumping or compacting, thus ensuring smooth discharge from the warehouse and effectively preventing blockages.

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses an anti-clogging powder magazine unblocking device. For example... Figure 1 As shown, it includes a load-bearing vertical plate 1, and a snap-fit ​​fastener 2 is fixedly installed in the middle of the outer side of the load-bearing vertical plate 1. A limit plate is slidably installed inside the snap-fit ​​fastener 2. A bolt rod is rotatably installed on the top of the limit plate. The top of the bolt rod is rotatably installed in the middle position of the top of the snap-fit ​​fastener 2. The load-bearing vertical plate 1 is installed in multiple working positions through the snap-fit ​​fastener 2, thereby increasing the number of working positions of the air flow aid 4.

[0024] Please see Figure 2A fixing plate 3 is fixedly installed in the middle of the inner side of the load-bearing vertical plate 1. An air flow aid 4 is fixedly installed at the end of the fixing plate 3 away from the load-bearing vertical plate 1. The air flow aid 4 uses an existing design, which will not be described in detail here. A pipe 5 is fixedly connected to the end of the air flow aid 4 away from the fixing plate 3. A union sleeve 7 is connected to the end of the pipe 5 away from the air flow aid 4. The union sleeve 7 consists of two parts. A limiting track plate 15 is fixedly installed at the top of the outer side of the union sleeve 7. A locking rod 16 is fixedly installed at the bottom of the outer side of the union sleeve 7. The locking rod 16 is C-shaped. The limiting track plate 15 is fixedly installed. One end is rounded. Two limiting track plates 15 are symmetrically arranged on both sides of the outer circumference of each swivel sleeve 7. The two swivel sleeves 7 are symmetrically arranged. Two limiting track plates 15 are provided on the outer side of each of the two swivel sleeves 7 and are staggered and symmetrical. After rotating a certain angle, the staggered and symmetrical limiting track plates 15 can engage with two sets of locking rods 16. The two parts of the swivel sleeve 7 are engaged under the action of the locking rods 16, so that the two swivel sleeves 7 can be tightly connected together. The "C"-shaped locking rods 16 engage with the limiting track plates 15 more tightly.

[0025] Please see Figure 2 and Figure 4 The bottom of the union sleeve 7 is connected to a central connecting pipe 8. A plug tube 18 is fixedly installed at the bottom of the central connecting pipe 8. An outer sleeve 17 is fixedly installed at the top of the plug tube 18. The diameter of the outer sleeve 17 is larger than that of the pipe 5. A fixing ring 6 is snapped onto the upper part of the outer sleeve 17. A bolt rod is installed at the connection of the fixing ring 6. Under the action of the fixing ring 6, the top of the outer sleeve 17 is in close contact with the outer side of the pipe 5, which increases the sealing of the plug tube 18 after it is connected to the pipe 5. A connecting ring 22 is fixedly installed in the middle of the inner wall of the union sleeve 7. An inner network tube 20 is fixedly installed at the bottom of the connecting ring 22. An outer sleeve 21 is slidably sleeved on the outer side of the inner network tube 20. The bottom of the outer sleeve 21 is fixedly installed at the bottom of the inner wall of the lower union sleeve 7. The inner network tube 20 is inserted into the inside of the outer sleeve 21, which increases the sealing of the two union sleeves 7 after they are connected.

[0026] Please see Figure 2 and Figure 5 A bottom sleeve 11 is fixedly provided at the bottom of the inner wall of the plug-in sleeve 18. A sliding groove 12 is fixedly provided on the inner wall of the bottom sleeve 11. An elastic plate 10 is fixedly provided at the bottom of the inner wall of the sliding groove 12. The elastic plate 10 is arc-shaped. The top of the elastic plate 10 is fixedly provided at the bottom of the inclined rod 9 near the bottom sleeve 11. The elastic plate 10 supports the bottom of the inclined rod 9. Under the action of the elastic plate 10, the blocking plate 13 is always in contact with the fascia below the bottom limiting ring 14.

[0027] Please see Figure 2 and Figure 5A sliding plate 19 is slidably mounted on the top of the inner wall of the slide groove 12. One end of the sliding plate 19 is rotatably mounted with a diagonal rod 9. The other end of the diagonal rod 9 is rotatably mounted on the blocking plate 13 via a rotating plate. The middle part of the outer side of the blocking plate 13 is rotatably mounted on the bottom limiting ring 14 via a rotating rod. The middle part of the bottom limiting ring 14 is provided with a through hole. The diameter of the through hole in the middle part of the bottom limiting ring 14 is smaller than the diameter of the blocking plate 13. The upper surface of the blocking plate 13 slides in contact with the bottom of the bottom limiting ring 14. When the blocking plate 13 is stationary, it can seal the bottom of the bottom limiting ring 14 to prevent dust from entering the top of the bottom limiting ring 14 and increase the sealing performance. The outer side of the bottom limiting ring 14 is fixedly mounted on the middle part of the inner wall of the insertion cylinder 18.

[0028] The implementation principle of the anti-blockage powder silo unblocking device in this application embodiment is as follows: During use, under the action of two sets of union sleeves 7, the pipe 5 is connected to the lower plug cylinder 18. The top of the outer sleeve 17 is tightened so that its inner wall is in close contact with the outer wall of the pipe 5. The air flow aid 4 is activated to suddenly eject a strong airflow of compressed gas, which exceeds Mach 1 (sonic speed) and directly rushes into the interior of the powder silo. The high-speed gas moves the blockage plate 13 away from the bottom limit ring 14 and opens the bottom of the bottom limit ring 14, making it easier for the gas to rush into the blocked position of the powder silo. The sudden release of the expansion shock wave overcomes the static friction of the material and restores the flow of the material in the container. After the air flow aid 4 is turned off, the blockage plate 13 is reset under the action of the elastic plate 10 to seal the bottom of the plug cylinder 18, preventing powder from entering and causing damage to the equipment. When maintenance is required, the plug cylinder 18 can be separated from the pipe 5 by rotating the union sleeve 7 in the opposite direction to facilitate cleaning the interior.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
