Description

Technical Field

[0001] This invention relates to the field of ash discharge valve technology, and in particular to a self-locking ash discharge bell valve. Background Technology

[0002] Ash discharge valves are key components of dust removal equipment for ash discharge, air supply, and feeding other equipment. They are suitable for both powdery and granular materials and are widely used in environmental protection, metallurgy, chemical, grain, food, and power industries.

[0003] Ash discharge valves are often vertically installed to meet the needs of ash discharge. When using a flip-top type ash discharge valve, it often needs to bear the weight of the material in the entire pipeline. It cannot be used when the pipeline is thick and the load is heavy. Conical bell valves can effectively solve this problem. However, when the conical bell valve is closed, it needs to bear the pressure through a drive element. Conical bell valves without self-locking function may cause the drive element to be damaged and automatically discharge material. In addition, the design of the conical bell valve cannot apply enough kinetic energy to the material in the pipeline during the opening process. Some wet and full materials may block the pipeline opening and make it difficult to discharge. Therefore, a self-locking valve position ash discharge bell valve is proposed. Summary of the Invention

The end of the output shaft extends into the ash discharge pipe and is connected to an ash discharge bearing column via an ash discharge connecting rod. A conical bell valve is connected to the end of the ash discharge bearing column via an elastic bearing element. A contraction fan-shaped element is located at the bottom of the conical bell valve. An inner shaft column is connected to the top of the ash discharge bearing column via a movable element. Locking columns are evenly connected to the outer wall of the inner shaft column via folding rods. The ash discharge pipe is connected to an inner locking ring via a manual locking element. An "L"-shaped locking groove adapted to the locking column is opened on the inner side wall of the inner locking ring.

[0007] Preferably, the self-locking component includes multiple T-shaped telescopic openings on the outer wall of the self-locking ring, and the inner wall of the T-shaped telescopic opening is connected to a locking plate by a contact spring, and the locking plate is provided with a magnetic locking contact post;

[0008] A locking sleeve is fixedly connected to the outer wall of the ash discharge pipe. The locking sleeve is sleeved on the output shaft and is fixedly connected to an electromagnetic ring. A locking hole is opened on the locking sleeve located at the electromagnetic ring for the magnetic locking contact post to be adapted.

[0009] Preferably, both ends of the ash discharge connecting rod are fixedly connected to connecting plates, and the ends of the output shaft and the ash discharge bearing column are fixedly connected to U-shaped rotating blocks. The U-shaped rotating blocks and the connecting plates are rotatably connected by a rotating shaft.

[0010] Preferably, the elastic bearing member includes a limiting elastic column cavity opened in the conical bell valve, and a bearing ring is fixedly connected to the outer wall of the bearing column located in the limiting elastic column cavity. The bearing ring is connected to the inner wall of the limiting elastic column cavity through a rigid bearing spring sleeved on the bearing column.

[0011] Preferably, the shrinkable fan-shaped component includes fan-shaped expansion blocks evenly distributed at the bottom of the conical bell valve, adjacent fan-shaped expansion blocks are connected by movable arc rods, and both the fan-shaped expansion blocks and the movable arc rods are connected to the conical bell valve by folded abrasion-resistant fabric.

[0012] Preferably, the bottom of the conical bell valve is rotatably connected to a linkage turntable via a connecting sleeve. The outer wall of the linkage turntable is uniformly provided with abutting protrusions that abut against the fan-shaped expansion block. The inner wall of the linkage turntable is provided with a spiral linkage port. The outer wall of the ash unloading bearing column is fixedly connected with a linkage spherical column that matches the spiral linkage port.

[0013] Preferably, an upper top plate is fixedly connected to the top of the inner shaft column, a movable abutment ring is slidably arranged on the inner shaft column, and the folding rod is composed of two linkage folding rods that are rotatably connected to the locking column. The two ends of the linkage folding rods are respectively rotatably connected to the movable abutment ring and the upper top plate.

[0014] Preferably, the movable component includes a cylindrical sliding opening at the top of the ash unloading support column, the inner shaft column is located inside the cylindrical sliding opening, and the movable abutment ring is connected to the ash unloading support column through an abutment spring sleeved on the outer wall of the inner shaft column.

[0016] Preferably, the bell valve seat is adapted to the conical bell valve, and the outer wall of the conical bell valve is provided with a rubber sealing ring.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention cleverly uses a self-locking component on the output shaft of a hydraulic unloading pump and an electromagnetic ring to control the release of the self-locking component. The design cleverly utilizes the movement of the output shaft depending on whether the hydraulic unloading pump is damaged or not, so that the electromagnetic ring cannot release the limit of the self-locking component after the hydraulic unloading pump is damaged. This achieves the effect of automatically opening the self-locking protection when the drive component is damaged, thus avoiding accidents.

[0019] 2. This invention addresses the problem that current conical bell valves occupy pipeline space for unloading, resulting in obstructed unloading. It sets up a spherical cavity for unloading ash on the pipeline and transforms the complete conical bell valve into a foldable wear-resistant fabric that can expand and contract, so that the inner diameter automatically changes after the valve is opened, thereby improving the conveying efficiency.

[0020] 3. This invention utilizes the relative movement between the ash discharge bearing column and the conical bell valve, so that when opened, the ash discharge bearing column drives the unfolded linkage lever to reset. During the reset process, multiple linkage levers will cut the material accumulated on the conical bell valve and apply force to the material, so that the material that cannot be discharged due to clumping can be easily discharged, avoiding material blockage, and achieving the effect of applying material force to the flip-top unloading valve.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example

[0031] Reference Figure 1-7 A self-locking ash discharge bell valve includes an ash discharge pipe 1, with pipe connection flanges 2 at both ends of the ash discharge pipe 1 to achieve effective connection with the ash discharge pipe of the ash discharge equipment; the ash discharge pipe 1 has an ash discharge spherical cavity 3 inside, and a bell valve seat 4 is provided on the side wall of the ash discharge pipe 1 located at the top of the ash discharge spherical cavity 3.

[0032] It should be noted that after the conical bell valve 10 is opened, the conical bell valve 10 is located at the ash discharge spherical cavity 3. The advantage of setting the ash discharge spherical cavity 3 is that the conical bell valve 10 is circular and will occupy a certain space of the ash discharge pipe 1 during the discharge process. By setting the ash discharge spherical cavity 3, the space can be effectively compensated to ensure the smooth discharge process.

[0033] A hydraulic unloading pump 5 is installed at one end of the ash unloading pipe 1. The hydraulic unloading pump 5 is existing technology and will not be described in detail here. The output end of the hydraulic unloading pump 5 is connected to an output shaft 6. A self-locking ring 7 is fixedly connected to the outer wall of the output shaft 6. Multiple self-locking components are evenly arranged on the outer wall of the self-locking ring 7. Further, the self-locking components include multiple T-shaped telescopic openings opened on the outer wall of the self-locking ring 7. The inner wall of the T-shaped telescopic opening is connected to a locking plate 15 through a contact spring. A magnetic locking contact post 16 is provided on the locking plate 15.

[0034] A locking sleeve is fixedly connected to the outer wall of the ash discharge pipe 1. The locking sleeve is sleeved on the output shaft 6 and is fixedly connected to an electromagnetic ring 17. A locking hole for the magnetic locking contact post 16 to be adapted is opened on the locking sleeve located at the electromagnetic ring 17.

[0035] It should be noted that when the electromagnetic ring 17 is energized, it can generate a magnetic force. The magnetic force of the electromagnetic ring 17 is opposite to the magnetic force of the magnetic locking contact post 16, and can generate a magnetic repulsion force. Under normal circumstances, with the normal support of the hydraulic unloading pump 5, the magnetic locking contact post 16 is in the middle position of the locking hole and does not contact the side wall of the locking hole, that is, no friction force is generated. At this time, the magnetic locking contact post 16 can be retracted.

[0036] When the hydraulic unloading pump 5 fails, the gravity of the material will cause the output shaft 6 to move, and the magnetic locking contact 16 will come into contact with the side wall of the locking hole. At this time, when the electromagnetic ring 17 is opened, the magnetic force of the electromagnetic ring 17 will not be able to effectively retract the magnetic locking contact 16.

[0037] The output shaft 6 extends into the ash discharge pipe 1 and is connected to the ash discharge bearing column 9 via the ash discharge connecting rod 8. Furthermore, both ends of the ash discharge connecting rod 8 are fixedly connected to connecting plates 18, and both ends of the output shaft 6 and the ash discharge bearing column 9 are fixedly connected to U-shaped rotating blocks. The U-shaped rotating blocks and the connecting plates 18 are rotatably connected via a rotating shaft.

[0038] The end of the ash discharge bearing column 9 is connected to a conical bell valve 10 through an elastic bearing member. The ash discharge bearing column 9 and the conical bell valve 10 are in sliding contact. Furthermore, the elastic bearing member includes a limiting elastic column cavity 19 opened in the conical bell valve 10. A bearing ring 20 is fixedly connected to the outer wall of the ash discharge bearing column 9 located in the limiting elastic column cavity 19. The bearing ring 20 is connected to the inner wall of the limiting elastic column cavity 19 through a rigid bearing spring sleeved on the ash discharge bearing column 9.

[0039] The further advantage of the above is that the rigid bearing spring does not compress when the conical bell valve 10 moves up and down normally. Its own elasticity supports its up and down movement. Only when the conical bell valve 10 is blocked when it contacts the bell valve seat 4 will it be able to press against the rigid bearing spring, and only then will the ash unloading bearing column 9 and the conical bell valve 10 move relative to each other.

[0040] The bell valve seat 4 is compatible with the conical bell valve 10, and the outer wall of the conical bell valve 10 is provided with a rubber sealing ring 35, which can ensure a sealing effect after contact.

[0041] The bottom of the conical bell valve 10 is provided with a retractable fan-shaped component. The retractable fan-shaped component can ensure the cleaning of excess material after contacting the valve seat 4, and can also automatically retract after opening, reducing the space occupied and improving the conveying efficiency. Furthermore, the retractable fan-shaped component includes fan-shaped expansion blocks 21 evenly distributed at the bottom of the conical bell valve 10. Adjacent fan-shaped expansion blocks 21 are connected by movable arc rods 22. Both the fan-shaped expansion blocks 21 and the movable arc rods 22 are connected to the conical bell valve 10 through folded wear-resistant fabric 23. The movable arc rods 22 can slide and extend within the fan-shaped expansion blocks 21, and their material is rubber, which has a certain degree of flexible bending angle compensation.

[0042] The bottom of the conical bell valve 10 is rotatably connected to the linkage turntable 24 through the connecting sleeve. The outer wall of the linkage turntable 24 is evenly provided with abutting protrusions 25 that abut against the fan-shaped expansion block 21. The inner wall of the linkage turntable 24 is provided with a spiral linkage port 26. The outer wall of the ash unloading bearing column 9 is fixedly connected with a linkage spherical column 27 that is adapted to the spiral linkage port 26.

[0043] It should be noted that when the ash unloading support column 9 moves upward, the linkage ball column 27 will move into the spiral linkage port 26. At this time, when the ash unloading support column 9 moves upward, the vertical force will be converted into rotational force through the linkage ball column 27, causing the linkage turntable 24 to rotate, driving the abutment protrusion 25 to move, thereby achieving the effect of unfolding the fan-shaped expansion block 21, and thus achieving the effect of changing the inner diameter.

[0044] The top of the ash unloading support column 9 is connected to an inner shaft column 11 via a movable component. The inner shaft column 11 is fixedly connected to the conical bell valve 10 via multiple inclined rods staggered between the linkage folding rods 29, thereby limiting the movement of the inner shaft column 11. Furthermore, an upper top plate 28 is fixedly connected to the top of the inner shaft column 11, and a movable abutment ring 30 is slidably arranged on the inner shaft column 11. The folding rod component consists of two linkage folding rods 29 that are rotatably connected to the locking column 12. The two ends of the linkage folding rods 29 are rotatably connected to the movable abutment ring 30 and the upper top plate 28, respectively. All of the above-mentioned rotatable connection methods are shaft and hole mating connections.

[0045] It is worth noting that when the linkage lever 29 is in a vertical state, it is within the coverage area of ​​the upper plate 28. This effectively reduces the resistance of the linkage lever 29 to the material and ensures rapid material feeding.

[0046] The movable component includes a cylindrical sliding opening at the top of the ash discharge bearing column 9, with the inner shaft column 11 located inside the cylindrical sliding opening. The movable contact ring 30 is connected to the ash discharge bearing column 9 via a contact spring sleeved on the outer wall of the inner shaft column 11, achieving elastic contact and preventing damage to the equipment when hard objects are present.

[0047] Locking pins 12 are evenly connected to the outer side wall of the inner shaft column 11 by folded rods. The ash discharge pipe 1 is connected to the inner locking ring 13 by a manual locking device. The inner side wall of the inner locking ring 13 is provided with an "L"-shaped locking slot 14 that matches the locking pin 12. When the inner shaft column 11 continues to move upward, it will eventually unfold and tend to be set horizontally. At this time, the locking pin 12 will be inserted into the "L"-shaped locking slot 14. When it is necessary to manually lock it from the outside, simply rotate the inner locking ring 13 to achieve the locking effect of the entire bell valve.

[0048] Furthermore, the manual locking component includes a control cover 34 installed on the ash discharge pipe 1. The inner wall of the control cover 34 is connected to a control gear 31 via a control shaft. The inner locking ring 13 is connected to an outer gear ring 33 via multiple connecting blocks 32 that penetrate the ash discharge pipe 1. The outer gear ring 33 is meshed with the control gear 31.

[0049] It should be noted that: the ash discharge pipe 1 has multiple through-holes for the connecting block 32 to move, and the side wall at the through-hole needs to be sealed with rubber gaskets to improve the sealing effect.

[0050] During normal use, the hydraulic unloading pump 5 extends and retracts outward, causing the output shaft 6 to move upward via the unloading connecting rod 8, thus moving the unloading bearing column 9 upward. The conical bell valve 10 connected to the unloading bearing column 9 comes into contact with the bell valve seat 4, achieving an effective seal upon contact. As the unloading bearing column 9 continues to move upward, two effects are achieved:

[0051] Firstly, the upper part will drive the movable contact ring 30 to move upward, so that the originally vertical linkage lever 29 gradually becomes horizontal, and finally the locking pin 12 on the linkage lever 29 moves into the "L"-shaped locking slot 14. When opened, the reset of the linkage lever 29 will enable the linkage levers 29 on all sides to cut the material accumulated on top, separate the clumps of material, and avoid blockage.

[0052] Secondly, when the ash unloading support column 9 located below moves upward, the linkage ball column 27 will move into the spiral linkage port 26. At this time, when the ash unloading support column 9 moves upward, the vertical force will be converted into rotational force through the linkage ball column 27, causing the linkage turntable 24 to rotate, driving the abutment protrusion 25 to move, thereby achieving the effect of unfolding the fan-shaped expansion block 21, and thus achieving the effect of changing the inner diameter. When it is opened during storage, it will automatically retract, reducing the space occupied and improving the conveying efficiency.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
