Description

Technical Field

[0001] The present application relates to the technical field of fly ash silo accessories, and specifically discloses a fly ash silo bottom ash collection and transportation device. Background Art

[0002] A semi-enclosed or fully enclosed site for storing fly ash is a fly ash silo. Generally speaking, a fly ash silo is a large storage tank with a conveying pipe at the bottom of the silo. A conveying trolley is used to transport the fly ash inside the silo. Please refer to the attached manual for details. Figure 1 ;

[0003] Fly ash, commonly known as fly ash, refers to the fine ash collected from the flue gas after coal combustion. It is the main solid waste discharged from coal-fired power plants.

[0004] Fly ash is usually gray or gray-black. The main oxide components of fly ash are SiO2, Al2O3, FeO, Fe2O3, CaO, TiO2, etc. Fly ash is widely used in the production of cement, mortar, concrete and other construction materials. In construction companies, the use of fly ash ingredients can help companies reduce raw material costs;

[0005] After a long period of transportation through the conveying pipe, the inner wall of the conveying pipe will be blocked, which will lead to a decrease in the transportation efficiency of the fly ash. In view of this, the inventor proposes a fly ash silo bottom ash collection and transportation device. Utility Model Content

[0026] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0027] The figure marks in the drawings of the specification include: connecting pipe 1, tilting pipe 2, electric switch valve 3, sliding groove 4, mounting block 5, compression spring 6, traction rope 7, torsion spring 8, cleaning plate 9, iron block 10, magnet block 11, sliding block 12.

[0028] Implementation example Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown:

[0029] A fly ash silo bottom ash collection and conveying device, comprising a conveying component arranged at the bottom of the fly ash silo, wherein an electric switch valve 3 is arranged at the connection between the conveying component and the fly ash silo;

[0030] The conveying component is a tubular structure, the pipe body includes a connecting pipe 1 and an inclined pipe 2, the inclined pipe 2 is a seamless splicable pipe, and the use of a seamless splicable pipe can facilitate the subsequent cleaning of the mechanical cleaning component, the electric switch valve 3 is connected to the connecting pipe 1, and the mechanical cleaning component is arranged inside the inclined pipe 2. The tubular structure includes a pipe body and a mechanical cleaning component arranged inside the pipe body;

[0031] The mechanical cleaning component includes a sliding groove 4 symmetrically opened on the inner wall of the tube body, a compression spring 6 arranged in the sliding groove 4, a torsion spring 8 arranged at the end of one of the compression springs 6, a cleaning plate 9 arranged at the torsion end of the torsion spring 8, and a traction rope 7. The traction rope 7 is arranged at the bottom of the cleaning plate 9 and is pulled out from the tube body.

[0032] Specifically, the bottom of the compression spring 6 is fixed to the mounting block 5 in the sliding groove 4, and then the torsion spring 8 is arranged on the compression spring 6 on the left, and a sliding block 12 is arranged at the left end of the torsion spring 8, and the sliding block 12 is slidably connected to the inner bottom of the sliding groove 4, so as to facilitate the sliding of the torsion spring 8.

[0033] Then, if Figure 4 As shown, an iron block 10 is provided at the bottom of the cleaning plate 9 on the right side away from the sliding block 12, and a magnet block 11 is provided at the free end of the compression spring 6 in the sliding groove 4 on the same side. When the cleaning plate 9 rotates, the iron block 10 can be magnetically connected to the magnet block 11. The sliding stability of the cleaning plate 9 is improved, and when the iron block 10 can be magnetically connected to the magnet block 11, the cleaning plate 9 is in a horizontal state. When the cleaning plate 9 is in a horizontal state, the outer side of the cleaning plate 9 can contact the inner wall of the inclined tube 2. The cleaning effect of the cleaning plate 9 is improved, and a protrusion is provided on the top of the cleaning plate 9, and the protrusion can collide with the inner wall of the inclined tube 2. Provide a certain vibration cleaning effect.

[0034] Specific implementation process:

[0035] In the first step, the electric switch valve 3 is started, and the fly ash stored in the fly ash reservoir begins to pour out and enter the inclined pipe 2 along the connecting pipe 1. The transport trolley waits at the output end of the inclined pipe 2 and starts transportation;

[0036] Second, with the long-term and frequent use of the inclined tube 2, fly ash will accumulate on the inner wall of the inclined tube 2, thereby causing a decrease in the conveying efficiency. Even with the inclined tube 2, the decrease in the conveying efficiency is visible to the naked eye;

[0037] The third step, at this time, it is necessary to close the electric switch valve 3 first, then move the conveying trolley, pull the traction rope 7, the traction rope 7 drives the cleaning plate 9, the cleaning plate 9 is under the action of the traction rope 7 and the torsion spring 8 from the vertical state, gradually moves to the horizontal state, and then the iron block 10 begins to be magnetically connected with the magnet block 11, and then, continue to pull the traction rope 7, the cleaning plate 9 compresses the compression spring 6, and the cleaning plate 9 begins to work on the inner wall of the inclined tube 2 to achieve dust cleaning of the inner wall of the inclined tube 2. After repeated several times, release the traction rope 7, the torsion spring 8 is reset, and the protrusion collides with the inner wall of the inclined tube 2 to provide a certain vibration force to assist in cleaning.

[0038] Finally, when the traction rope 7 is initially pulled, in order to make the torsion spring 8 twist first and the compression spring 6 not shift in position, the compression spring 6 needs to use a multi-turn, high-carbon material compression spring 6 to overcome the traction rope 7 generated by the initial traction rope 7. Although it will make the compression of the compression spring 6 more difficult, the fact that the compression spring 6 does not shift in position can increase the service life of the compression spring 6.

[0039] The device solves the problem that after a traditional fly ash storage conveying device has been transporting fly ash for a long time, fly ash is accumulated in the conveying device, thereby reducing the conveying efficiency.

[0040] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
