Description

Technical Field

[0001] This invention relates to the field of anti-clogging technology for cylindrical valve bodies, specifically an anti-clogging device for a lock-type unloading valve. Background Technology

[0002] An airlock discharge valve is a device used to control the flow of air and materials, primarily in industrial applications requiring controlled gas and material flow. They are widely used in silos, conveying systems, powder handling, and other fields. While the valve body shape can vary depending on the design and application, many common airlock discharge valves do employ a cylindrical body design. Cylindrical airlock discharge valves are typically used to control the flow of gas and materials, and their design makes them highly effective in maintaining system airtightness and stabilizing material flow.

[0003] Traditional airlock discharge valves, lacking modern anti-clogging devices, typically rely on periodic manual cleaning to ensure no material buildup and maintain normal operation, thus minimizing or preventing clogging. However, manual cleaning usually requires regular work by professionals, which can lead to high labor intensity and costs. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides an anti-clogging device for a lock-type unloading valve, which solves the problem of requiring regular manual cleaning of the valve. However, manual cleaning usually requires professional personnel to perform it regularly, which may lead to high labor intensity and labor costs.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: an anti-clogging device for a lock-type unloading valve, comprising:

[0008] The upper airbag, which serves as the main support for the entire device, is used to inflate or deflate the air according to the inner diameter of the airlock unloading valve.

[0009] A thickened rubber ring is fixed to the outer diameter of the upper airbag, serving to thicken and protect the outer diameter of the upper airbag;

[0010] Four rubber connecting blocks are fixed around the thickened rubber ring.

[0011] Four rubber rollers are vertically rotatable inside the four rubber connecting blocks, which are used to provide the upper airbag with the ability to move and operate.

[0012] The unblocking mechanism inside the airlock unloading valve is located within the inner diameter of the upper airbag. Below it, there is also an air blowing cleaning mechanism for unblocking the airlock unloading valve. Below the air blowing cleaning mechanism, there is also a cleaning mechanism for unblocking and cleaning before air blowing.

[0013] Preferably, the unblocking mechanism includes a fixed plate fixed to the inner diameter of the upper airbag, a drive motor passing through and fixed above the upper airbag, and a rotating rod fixed to the output end of the drive motor.

[0014] Preferably, the outer diameter of the rotating rod is fixed with multiple sets of disintegrating plates, and the bottom end of the rotating rod is fixed with a slotted cone head, which is used to unclog the inside of the blocked airlock unloading valve.

[0015] Preferably, the air-blowing cleaning mechanism includes an annular pipe and a ball bearing. The inner diameter of the ball bearing is fixed to the outer diameter of the rotating rod, and the ball bearing is located between the upper airbag and the dispersing plate. The annular pipe is located on the outer diameter of the ball bearing, and the annular pipe and the ball bearing are fixedly connected by multiple sets of connecting strips.

[0016] Preferably, the outer diameter of the annular pipe is permeated and fixed with multiple sets of air outlet pipes, which are used to discharge the gas entering the annular pipe. Four sets of evenly distributed branch pipes are permeated and fixed above the annular pipe, and the top ends of the four sets of branch pipes are all permeated with fixed plates. The top ends of the four sets of branch pipes are connected by air inlet pipes, which are used for gas injection and diverted into the annular pipe through the four sets of branch pipes.

[0017] Preferably, the cleaning mechanism includes a lower airbag and a connecting plate. The connecting plate is fixed to the outer diameter of the rotating rod and is located between the annular pipe and the disintegrating plate. The lower airbag is fixed to the outer diameter of the connecting plate. The outer surface of the lower airbag is equipped with evenly distributed soft brushes for cleaning the inner diameter of the airlock unloading valve.

[0018] Preferably, the diameter of the ring formed by the lower airbag and the soft brush is greater than or equal to the diameter of the circle formed by the upper airbag, the thickened rubber ring, and the rubber connecting block.

[0019] (III) Beneficial Effects

[0020] This invention provides an anti-clogging device for an airlock discharge valve. It has the following advantages:

[0021] 1. This invention uses a clearing mechanism to first remove large blockages, effectively reducing the obstruction of these objects to the subsequent cleaning and blowing process, and avoiding interference of blockages with the cleaning effect during the cleaning process.

[0022] 2. The present invention uses a cleaning mechanism to thoroughly clean the valve body wall immediately after unblocking. This step can completely remove the residue on the wall, keeping the inside of the valve body clean and thus further reducing the formation of new blockages.

[0023] 3. The present invention uses a blowing cleaning mechanism after brushing to blow away the residue that has not been brushed away, ensuring that the residue inside the valve body is completely removed, preventing the residue that may be missed during the brushing process, and further improving the cleaning effect.

[0024] In summary, the entire cleaning process can significantly reduce the occurrence of valve failures caused by accumulated residues or blockages, thereby reducing the frequency of equipment maintenance and downtime. It also ensures thorough cleaning of the valve body, which helps the equipment operate smoothly, improves overall operating efficiency, and reduces performance degradation and energy consumption caused by blockages.

[0025] 4. Regular and thorough cleaning with this device can reduce wear and malfunctions caused by scale buildup, as well as reduce or prevent the risk of future blockages, thereby extending the service life of the valve body and reducing long-term maintenance costs. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example:

[0035] Please see the appendix Figure 1 - Appendix Figure 6 This invention provides an anti-clogging device for a lock-type unloading valve, comprising:

[0036] The upper airbag 1, which serves as the main support for the entire device, is used to inflate or deflate according to the inner diameter of the airlock unloading valve.

[0037] Thickened rubber ring 2 is fixed to the outer diameter of the upper airbag 1, and is used to thicken and protect the outer diameter of the upper airbag 1;

[0038] There are four rubber connecting blocks 3, which are fixed around the thickened rubber ring 2 respectively;

[0039] There are four rubber rollers 4, which are vertically rotatable inside the four rubber connecting blocks 3, and are used to provide the upper airbag 1 with the ability to move and operate.

[0040] The unblocking mechanism 5 is located inside the airlock unloading valve. It is installed in the inner diameter of the upper airbag 1. Below it, there is also an air blowing cleaning mechanism 6 for unblocking the airlock unloading valve. Below the air blowing cleaning mechanism 6, there is also a cleaning mechanism 7 for unblocking and cleaning before air blowing.

[0041] In this embodiment, firstly, the device is inserted into the upper opening of the cylindrical airlock discharge valve. Then, the upper airbag 1 is inflated until its size is approximately the same as the inside of the cylindrical discharge valve. (Refer to the attached diagram) Figure 3 (The external part is a cross-section of a cylindrical airlock unloading valve), which makes the rubber roller 4 fit tightly against the inner wall of the cylindrical airlock unloading valve. Since only 1 / 3 of the rubber roller 4 is exposed and in contact with the wall, and a thickened rubber ring 2 with a thickness of 3-6mm is used to protect the outer diameter of the upper airbag 1, damage will be avoided when the upper airbag 1 comes into contact with the inner wall of the cylindrical airlock unloading valve.

[0042] Please see the appendix Figure 1 - Appendix Figure 4The unblocking mechanism 5 includes a fixed plate 51, which is fixed to the inner diameter of the upper airbag 1. A drive motor 52 is fixed through and fixed above the upper airbag 1, and a rotating rod 53 is fixed to the output end of the drive motor 52. Multiple sets of dispersing plates 54 are fixed to the outer diameter of the rotating rod 53. A slotted cone head 55 is fixed to the bottom end of the rotating rod 53, which is used to unblock the inside of the blocked airlock unloading valve.

[0043] In this embodiment, the rotating rod 53 is driven to rotate by the drive motor 52 in the unblocking mechanism 5. Due to the connection between the slotted cone 55 and the dispersing plate 54 and the rotating rod 53, the rotational motion is transmitted to the downstream dispersing plate 54 and the slotted cone 55. Therefore, the slotted cone 55 directly contacts the blockage material during rotation. Its cone structure and slotted design help to penetrate and clear the blockage material, ensuring the smooth flow inside the valve body. Then, the dispersing plate 54 mechanically disperses the remaining blockage material (the dispersing plate 54 is made of rubber or other soft materials to avoid damaging the components inside the valve body), helping to loosen the material from the valve body wall. Therefore, with the dual unblocking effect of the slotted cone 55 and the dispersing plate 54, the blockage material inside the valve body is cleared and falls out through the lower opening.

[0044] Please see the appendix Figure 3 and attached Figure 5 The air-blowing cleaning mechanism 6 includes an annular pipe 61 and a ball bearing 63. The inner diameter of the ball bearing 63 is fixed to the outer diameter of the rotating rod 53, and the ball bearing 63 is located between the upper airbag 1 and the dispersing plate 54. The annular pipe 61 is located on the outer diameter of the ball bearing 63, and the annular pipe 61 and the ball bearing 63 are fixedly connected by multiple sets of connecting strips 64. Multiple sets of air outlet pipes 62 are passed through and fixed on the outer diameter of the annular pipe 61, which are used to discharge the gas entering the annular pipe 61. Four sets of evenly distributed branch pipes 65 are passed through and fixed on the upper part of the annular pipe 61, and the top ends of the four sets of branch pipes 65 all pass through the fixed plate 51. The top ends of the four sets of branch pipes 65 are connected by air inlet pipes 66, which are used for gas injection and diverted to the annular pipe 61 through the four sets of branch pipes 65.

[0045] In this embodiment, since the annular pipe 61 is located between the upper airbag 1 and the dispersing plate 54, the valve body through which the annular pipe 61 and the air outlet pipe 62 of the air blowing cleaning mechanism 6 pass is cleared and cleaned. At this time, high-pressure gas is injected into the branch pipe 65 through the air inlet pipe 66, and then diverted to the annular pipe 61 and discharged to the valve body wall through multiple sets of air outlet pipes 62 to clean the blockages remaining on the wall after clearing. Under the action of the high-pressure airflow and after cleaning by the cleaning mechanism 7, the residues on the valve body wall can be blown off. In addition, since the annular pipe 61 is connected to the rotating rod 53 through the ball bearing 63, the annular pipe 61 will not rotate during the rotation of the rotating rod 53 under the action of the ball bearing 63.

[0046] Please see the appendix Figure 3 and attached Figure 6 The cleaning mechanism 7 includes a lower airbag 71 and a connecting plate 73. The connecting plate 73 is fixed to the outer diameter of the rotating rod 53 and is located between the annular pipe 61 and the dispersing plate 54. The lower airbag 71 is fixed to the outer diameter of the connecting plate 73. The outer surface of the lower airbag 71 is equipped with evenly distributed soft brushes 72, which are used to clean the inner diameter of the airlock unloading valve. The diameter of the ring formed by the lower airbag 71 and the soft brushes 72 is greater than or equal to the diameter of the ring formed by the upper airbag 1, the thickened rubber ring 2, and the rubber connecting block 3.

[0047] In this embodiment, since the lower airbag 71 is located between the annular pipe 61 and the dispersing plate 54, the interior of the valve body traversed by the lower airbag 71 and the soft brush 72 in the cleaning mechanism 7 is cleared. Therefore, as the clearing mechanism 5 continuously rotates to clear the interior, and since the lower airbag 71 is connected to the rotating rod 53 via the connecting plate 73, the lower airbag 71 drives the soft brush 72 to rotate along with the rotating rod 53 during rotation. (The lower airbag 71 and the upper airbag 1 are inflated simultaneously, so that the soft brush 72 on the outer surface of the lower airbag 71 contacts the inner wall of the valve body). Since the lower airbag 71 is inflated, it can be inflated according to the size of the valve body, so that the soft brush 72 on the outer surface contacts the inner wall of the valve body. Therefore, when the clearing mechanism 5 clears the interior of the valve body, the cleaning mechanism 7 follows closely behind to clean the residue after clearing.

[0048] The device provided in this embodiment includes a dredging mechanism 5, an air-blowing cleaning mechanism 6, and a brushing mechanism 7. Its working sequence is as follows: first, the dredging mechanism 5 dredges the valve body; then, the brushing mechanism 7 brushes away residue from the valve body wall; finally, the air-blowing cleaning mechanism 6 uses high-pressure gas to blow away any remaining residue. Therefore, the dredging mechanism 5 first removes large blockages, reducing obstruction during subsequent brushing. The brushing mechanism 7 then thoroughly removes residue from the valve body wall, further reducing the likelihood of blockage formation. Finally, the air-blowing cleaning mechanism 6 uses high-pressure gas to blow away any remaining residue, ensuring thorough cleaning of the valve body and preventing recurrence of blockages. This device operates in sequence, ensuring the efficiency and effectiveness of each cleaning step and significantly reducing the risk of future blockages.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
