Description

Technical Field

[0001] The invention relates to the technical field of ash conveying devices, and in particular to an ash conveying optimization control device. Background Art

[0002] Pneumatic ash conveying, also known as air flow conveying, is a technology that uses the energy of air flow to convey granular materials along the air flow direction in a closed pipeline. Its basic principle is to use compressed air or other gases as the conveying medium to fluidize the material and then transport it through the pipeline.

[0003] Pneumatic ash conveying technology is widely used in many fields, especially in the ash handling system of thermal power plants, which can handle large amounts of dust and ash efficiently and environmentally friendly. In addition, pneumatic ash conveying systems are also widely used in industries such as metallurgy and chemical industry, as well as in the dust removal system of biomass boilers.

[0004] In the process of realizing the present invention, the inventors found that the prior art had the following problems: the silo pump in the existing ash conveying device is prone to blockage, and the reason for the blockage is that the ash sticks to the inner wall of the silo pump. As the ash conveying continues, more and more ash sticks to the wall, which may cause blockage. The cleaning process is time-consuming and labor-intensive. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides an ash conveying optimization control device, which solves the problem that the silo pump in the existing ash conveying device is prone to clogging. The reason for the clogging is that the ash sticks to the inner wall of the silo pump. As the ash conveying continues, more and more ash sticks to the wall, which may cause a blockage. The cleaning process is time-consuming and labor-intensive.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: an ash conveying optimization control device, comprising an ash conveying pipe, a pair of side plates are provided at the upper end of the ash conveying pipe, a sleeve is provided at the upper end of the ash conveying pipe and located between the pair of side plates, a fourth annular plate is provided in the sleeve, a through pipe is movably inserted in the fourth annular plate, an elastic part is connected between the through pipe and the upper end of the sleeve, a silo pump is provided at the upper end of the silo pump, an ash hopper is provided at the upper end of the silo pump, a dome valve is provided at the connection between the ash hopper and the silo pump, a driving mechanism and a buffer mechanism are provided between the silo pump and the pair of side plates, and the driving mechanism is located above the buffer mechanism.

[0011] Beneficial Effects

[0012] The present invention provides an ash conveying optimization control device. The present invention designs a structure for cleaning dust blockage inside a silo pump. The ash enters the silo pump through the ash hopper and then enters the ash conveying pipe. Whenever the ash conveying is completed, the vibration motor should be started to drive the silo pump to vibrate. During the process, a damper continuously applies resistance. After the vibration motor is turned off, the vibration of the silo pump gradually slows down, and the ash stuck to the inner wall surface of the silo pump can be shaken off. The device can shake off the ash that may be stuck to the wall surface of the silo pump during ash conveying by vibration, which reduces the problem of blockage, improves the internal cleaning effect, can greatly reduce the blockage maintenance work, and has strong practicality.

The slider 11 is slidably installed in the slide 10. The fixing portion 13 is connected to a spring telescopic rod 14. The upper end of the spring telescopic rod 14 is connected to the second annular plate 12, and a damper 15 is provided in the spring telescopic rod 14.

[0022] This embodiment is further configured such that a pair of side walls of the connecting plates 8 are each provided with a moving block, and a pair of side walls of the slots 16 are each provided with a sliding groove 22 , and the two pairs of moving blocks are respectively slidably installed in the two pairs of sliding grooves 22 .

[0024] The elastic member 18 is made of silicone material, which is deformable and can withstand high temperatures of more than 200 degrees. The temperature of the ash material for conveying ash is also 200 degrees, so it is applicable.

[0025] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0026] Embodiment: The ash material enters the silo pump 2 through the ash hopper 3, and then enters the ash conveying pipe 1 from the silo pump 2. One end of the ash conveying pipe 1 has an air pump to blow the ash material to the other end of the ash conveying pipe 1. Whenever the ash material is transported, the vibration motor 6 should be started to drive the vibration part 7 to vibrate. The vibration part 7 contacts the connecting plate 8, and the vibration pushes the connecting plate 8 to move downward. The first annular plate 9 moves downward with the connecting plate 8. The movement of the first annular plate 9 drives the silo pump 2 to move. The movement of the silo pump 2 drives the second annular plate 12 to move downward. The slider 11 is in Sliding in the slide 10, the outer ring of the spring telescopic rod 14 has a spring, and the inside is a telescopic rod. After receiving the downward force, the spring is compressed, and the telescopic rod retracts. The downward movement of the silo pump 2 will also drive the through pipe 19 to move downward. At this time, the elastic member 18 is deformed, and then the spring inside the spring telescopic rod 14 rebounds to lengthen the internal telescopic rod, so that the silo pump 2 is reset. During the process, the damper 15 continuously applies resistance. After turning off the vibration motor 6, the vibration of the silo pump 2 gradually slows down, and the ash material stuck to the inner wall surface of the silo pump 2 can be shaken off.
