Description

Technical Field

[0001] The utility model relates to the technical field of ash transportation and storage equipment, in particular to a leak prevention device for ash transportation and storage equipment. Background Technique

[0002] In the prior art, a bag leak prevention system for a waste power plant with the patent number "CN214972647U" is disclosed. When the ash unloading stops, the ash unloading valve and the leak prevention flap valve are closed simultaneously, so that the input end of the ash transportation pipeline is no longer connected to the output end of the ash transportation pipeline, realizing quickly and reliably isolating the ash hopper and the ash unloading valve from the outside world to prevent the outside humid gas from flowing reversely into the ash hopper and the ash unloading valve, and further realizing the function of preventing air leakage in the system. However, this patent can only be in the state of stopping ash unloading during use. However, when the equipment is working, the ash hopper and the ash transportation pipeline are still in a connected state, and as the working time extends, the connected state between the ash hopper and the ash transportation pipeline also extends. Therefore, the outside humid gas will also flow reversely into the ash hopper, causing the ash in the hopper to cake and reducing the transportation efficiency of fly ash. Content of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a leak prevention device for ash transportation and storage equipment is proposed.

[0004] To achieve the above purpose, the technical solution adopted by the utility model is: a leak prevention device for ash transportation and storage equipment, including an installation housing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0018] As Figures 1-5 shown, a leakage prevention device for ash transportation and storage equipment includes an installation housing 3. The internal cavity of the installation housing 3 is cylindrical. A transmission shaft 4 arranged coaxially is provided in the internal cavity of the installation housing 3. Both ends of the transmission shaft 4 penetrate and are installed on the surface of the installation housing 3. A plurality of baffles 7 are installed on the surface of the transmission shaft 4 by screws. Sealing rubber strips 8 are bonded to the surfaces of the plurality of baffles 7. The surface of the sealing rubber strip 8 contacts the inner surface of the installation housing 3. One end of the transmission shaft 4 is connected to a driving motor 1. When the ash hopper transports ash, the fly ash in the ash hopper falls into the installation housing 3. The spaced spaces between the plurality of baffles 7 are used to store the fly ash. As the plurality of baffles 7 rotate, the fly ash rotates to the lower part of the transmission shaft 4 and then falls. The other plurality of baffles 7 cooperate with the sealing rubber strips 8 to block the cavity in the installation housing 3, so that the device can reduce the inflow of external humid gas into the ash hopper while transporting the fly ash, delay the hardening progress of the fly ash in the ash hopper after contacting with moisture, and improve the stability of the environment in the ash hopper.

[0019] The housing of the driving motor 1 is installed with a motor support 2 by screws. One end of the motor support 2 is installed on the outside of the installation housing 3 by screws. The motor support 2 is used to support the driving motor 1, so that the driving motor 1 is in a stable working state.

[0020] Two symmetric sides of the installation housing 3 are both penetrated and installed with movable rods 15. One end of the movable rod 15 located inside the installation housing 3 is provided with a tapping rod 10. One end of the tapping rod 10 contacts the surface of the baffle 7. The other end of the movable rod 15 is installed with a stopper 6 by screws. A torsion spring 5 is movably sleeved on the surface of the movable rod 15. Both ends of the torsion spring 5 are installed on the outside of the installation housing 3 and the side surface of the stopper 6 by screws respectively. During the circular motion of the tapping rod 10 under force, the tapping rod 10 drives the movable rod 15 to rotate. After the movable rod 15 is stressed, the torsion spring 5 is twisted by the stopper 6. At this time, the torsion spring 5 is in an energy storage state. When the tapping rod 10 is not stressed, the torsion spring 5 drives the tapping rod 10 to return to its original position, which facilitates the tapping rod 10 to tap on the lower baffle 7. After the baffle 7 is stressed, it vibrates, and the vibration will clean the fly ash attached to the baffle 7, so that the fly ash falls onto the conveying equipment through the ash conveying pipeline for conveying operation.

[0021] Installation blocks 11 are installed on one end of the movable rod 15 located inside the installation housing 3 by screws. The side surface of the installation block 11 contacts the inner side surface of the installation housing 3, preventing the movable rod 15 from sliding out of the installation housing 3 and improving the stability of the tapping rod 10 during the circular motion.

[0022] Arc-shaped grooves 13 are provided on both symmetric inner sides of the installation housing 3. The arc-shaped grooves 13 are located on the arc-shaped trajectory of the racket rod 10. An arc-shaped rod 9 is installed inside the arc-shaped groove 13 by screws. Compression springs 12 and connecting blocks 14 are movably sleeved on the surface of the arc-shaped rod 9 respectively. Both ends of the compression spring 12 are installed on the surface of the connecting block 14 and the inner surface of the arc-shaped groove 13 by screws respectively. The surface of the connecting block 14 is installed at one end of the racket rod 10 by screws. When the racket rod 10 is stressed, it rotates on the installation housing 3 through the movable rod 15. At the same time, the racket rod 10 drives the connecting block 14 to slide on the arc-shaped rod 9. At the same time, the connecting block 14 applies pressure to the compression spring 12. After the compression spring 12 is stressed, its length shrinks. At this time, the compression spring 12 is in an energy storage state. When the racket rod 10 is not affected by external forces, the compression spring 12 drives the racket rod 10 to move in a reverse arc through its own elastic potential energy, which is convenient for the racket rod 10 to strike the baffle 7 located below, improving the convenience of operation.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
