Description

Technical Field

[0001] The utility model relates to the technical field of cyclone flap valves, in particular to a flap valve chain fixing device. Background Art

[0002] The cyclone is a device used for gas-solid separation or gas-liquid separation. A flap valve is installed at the vertebral part of the cyclone barrel to prevent air from entering from the bottom of the cyclone barrel, preventing the separated materials from being carried by the air flow again, so that the separated materials in the cyclone barrel can be discharged smoothly, ensuring the continuity of the material flow of the entire system;

[0003] The flap valve at the bottom of the above-mentioned cyclone barrel relies on the gravity of the material. When the material accumulates to a certain extent, the gravity of the material overcomes the resistance of the flap, causing the flap to open and the material to be discharged. After the material is discharged, the flap automatically closes under the action of its own gravity or counterweight and returns to a closed state to prevent air from entering. When maintenance personnel are inspecting the equipment downstream of the cyclone barrel, the material will fall down after accumulation to a certain extent, burying the maintenance personnel below, posing a great safety risk.

[0004] In summary, a device capable of fixing a flap valve is currently needed. Utility Model Content

Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0025] To solve the technical problems in the background art, the following flap valve chain fixing device is provided:

[0026] Combined with Figures 1 - 6As shown, the flap valve chain fixing device provided by the utility model comprises a base 1, a mounting vertical plate 11 and a mounting vertical plate 2 12 are provided on the top surface of the base 1, a retracting mechanism 2 is provided between the mounting vertical plate 11 and the mounting vertical plate 2 12, a wire rope chain 3 is provided in the middle of the retracting mechanism 2, the wire rope chain 3 can be connected with the control rod 61, the retracting mechanism 2 can achieve the purpose of fixing the control rod 61 by controlling the winding length of the wire rope chain 3, the end of the wire rope chain 3 away from the retracting mechanism 2 is fixedly connected to the end of the control rod 61 on the side of the flap valve 6 body, a fixing mechanism 4 for fixing the position of the retracting mechanism 2 is provided on the top side of the mounting vertical plate 11, an auxiliary fixing blocking mechanism 5 is provided at the end of the base 1, the retracting mechanism 2 comprises a retracting rod 21, a retracting disk 1 22 and a retracting disk 23, the retracting rod 21 is arranged through the middle of the mounting vertical plate 11 and the mounting vertical plate 2 12, the retracting rod 21 and the mounting vertical plate 11 and the mounting vertical plate 2 12 are all rotatably connected, the middle of the retracting rod 21 is provided with a retracting disc 1 22 and a retracting disc 23, the retracting rod 21 can drive the retracting disc 1 22 and the retracting disc 23 to rotate, so that the wire rope chain 3 is reeled in the reeling area, the retracting disc 1 22 and the mounting vertical plate 2 12 are fitted and slid, and the middle of the retracting disc 1 22 and the retracting disc 23 form a reeling area, the end of the retracting rod 21 is provided with a handle 25 for convenient operation by the staff, and the side of the retracting disc 2 23 is provided with a fixing groove 24 connected and fixed to the fixing mechanism 4, the fixing grooves 24 are arranged in a ring, and the fixing grooves 24 are convenient for the fixing mechanism 4 to fix the retracting mechanism 2;

[0027] In this embodiment, the fixing mechanism 4 includes a fixing block 41 and a fixing plug rod 42. The fixing block 41 is arranged on the top side of the mounting vertical plate 11. A fixing plug rod 42 engaged with the fixing groove 24 is arranged inside the fixing block 41. The fixing plug rod 42 passes through the middle of the fixing block 41. The fixing plug rod 42 engages and slides with the fixing block 41. When the retracting mechanism 2 rewinds the wire rope chain 3 to fix the position of the control rod 61, the fixing plug rod 42 can be inserted into the fixing groove 24 to limit the position of the retracting disk 23, ensuring that the retracting mechanism 2 and the wire rope chain 3 can maintain the state of the fixed control rod 61, thereby ensuring that the flap valve 6 is always in a closed state.

[0028] As an improvement of the above scheme, the end of the fixed plug rod 42 passes through the mounting vertical plate 11 and is engaged with the fixed groove 24. The end of the fixed plug rod 42 is an arc-shaped structure. After the fixed plug rod 42 with an arc-shaped end is engaged with the fixed groove 24, it can only be fixedly engaged with the retractable disk 23 in one direction. When the retractable disk 23 is reversed, the fixed plug rod 42 will be squeezed out of the fixed groove 24. In this way, during the process of the retractable mechanism 2 retracting the wire rope chain 3, the fixed plug rod 42 can not affect the rotation of the retractable mechanism 2. At the same time, after the retracting is completed, it is engaged with the fixed groove 24 to fix the retracted position of the wire rope chain 3.

[0029] In this embodiment, an activity cavity is formed inside the fixed block 41. A movable block 43 is arranged on the middle side of the fixed insertion rod 42. A spring 44 is arranged on the side of the movable block 43. The movable block 43 is engaged and slid with the activity cavity. The spring 44 can support the fixed insertion rod 42 through the movable block 43, so that after the fixed insertion rod 42 is extruded from the fixed groove 24, the fixed insertion rod 42 can be pushed to move again, ensuring that when the fixed groove 24 and the fixed insertion rod 42 are on the same horizontal line, the fixed insertion rod 42 can be engaged with the fixed groove 24;

[0030] When the flap valve 6 chain fixing device does not need to fix the flap valve 6, the staff pulls the fixed insertion rod 42 outwards. At this time, the valve plate inside the flap valve 6 will drive the control rod 61 to rotate under the pressure of the material. At this time, the push rod will pull the steel wire rope chain 3, causing the winding and unwinding mechanism 2 to rotate. To avoid damage to the steel wire rope chain 3 caused by the rapid pulling of the control rod 61, the following design is given in this embodiment:

[0031] The blocking mechanism 5 includes a blocking block 51, a blocking rod 52 and a support block 53. The blocking block 51 is arranged in the middle of the top surface of the base 1. A blocking rod 52 is arranged in the middle of the blocking block 51. The blocking rod 52 is threadedly connected with the blocking block 51. The blocking rod 52 threadedly connected with the blocking block 51 can stably move inside the blocking block 51. A connecting block 521 is arranged at the end of the blocking rod 52. The connecting block 521 is located inside the support block 53. The connecting block 521 is engaged and rotated with the support block 53. The connecting block 521 rotatably connected with the support block 53 can cooperate with the blocking rod 52 to push the support block 53 to move. The support block 53 is in sliding contact with the side surfaces of the first mounting vertical plate 11 and the second mounting vertical plate 12. During the process of the support block 53 being pushed by the blocking rod 52, it can fit and slide with the side surfaces of the first mounting vertical plate 11 and the second mounting vertical plate 12, ensuring the stable movement of the support block 53;

[0032] As an improvement of the above solution, a blocking pad 54 is arranged on one side of the top of the support block 53. The blocking pad 54 is inclined. The blocking pad 54 is in fitting contact with the edges of the second winding and unwinding disc 23 and the first winding and unwinding disc 22. The inclined blocking pad 54 on the side of the support block 53 can fit and press against the edges of the first winding and unwinding disc 22 and the second winding and unwinding disc 23, achieving the purpose of buffering the rapid movement of the winding and unwinding mechanism 2 and the steel wire rope chain 3, and further being able to reduce the pulling force on the steel wire rope chain 3, so as to improve the service life of the fixing device.
