Description

Technical Field

[0001] This invention relates to the field of ash transport control devices, and more specifically to a unit ash transport control room. Background Technology

[0002] The flue gas produced by power plant boilers contains a large amount of dust particles. After the flue gas is filtered by a dust collector, the particulate matter in the flue gas is collected in the ash hopper at the bottom of the dust collector; the collected particulate matter is called fly ash. In conventional designs, the dust collector ash hopper can store a maximum of 8 hours' worth of fly ash. Therefore, power plants need to set up dedicated fly ash silos to store fly ash, meeting the 24-48 hour storage requirements stipulated in regulations. Fly ash silos are generally located in areas far from the boiler room, and the fly ash in the dust collector ash hopper is transported to the fly ash silo for storage via pneumatic conveying.

[0003] When discharging ash from existing ash silos, on-site operators cannot directly observe the storage volume inside the material car. They rely entirely on the experience of the staff to operate the equipment. This makes it easy for the material car to overload the ash tanker or for the ash to overflow or fail to discharge into the tanker's inlet. Moreover, the ash spills out during discharge, and the visibility of the working environment is poor, which greatly increases the difficulty of controlling the discharge.

[0004] Therefore, it is urgent to improve the ash transport control room of the unit to achieve external visual observation and operation in order to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a unit ash handling control room that can effectively solve the problems mentioned above, such as the inability to visualize the ash handling and discharge process, leading to excessive or insufficient discharge and high reliance on human intervention.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a unit ash transport control room, comprising a base plate, a first mounting frame connected to the right side of the top of the base plate, an ash silo body connected to the inner side of the first mounting frame, a dustproof silo connected to the middle of the top of the base plate, a conveying module connected to the center of the top of the dustproof silo, a fixed discharge pipe connected to the bottom of the conveying module through the dustproof silo, a limiting groove opened on the inner side of the fixed discharge pipe, a movable discharge pipe 8 slidably connected to the inner side of the limiting groove, an annular dustproof cover connected to the outer side of the movable discharge pipe 8, a dust cleaning groove connected to the lower part of the inner cavity of the annular dustproof cover, a dust suction port opened on the inner side of the dust cleaning groove, a flexible pipe connected to the right side of the dust cleaning groove through the annular dustproof cover, a connecting groove connected to the right side of the dustproof silo, and the other end of the flexible pipe connected to the left side of the connecting groove, a dust conveying pipe connected to the middle of the left side of the ash silo body, and the other end of the dust conveying pipe connected to the right side of the connecting groove.

[0008] Preferably, the dustproof chamber is connected to spray pipes on both the front and rear sides, and spray nozzles are arranged and connected to the bottom of the spray pipes. The left side of the spray pipe is connected to the top of the water supply pipe, so that the water supply pipe can draw water into the spray pipe and spray it downward through the spray nozzles to separate the dust generated in the dustproof chamber from the outside.

[0009] Preferably, the inner side of the annular dust cover is connected to a limiting ring, and the bottom of each limiting ring is connected to a camera, so that the limiting ring can drive the camera to move vertically with the annular dust cover.

[0010] Preferably, a connecting ring is connected to the outer side of the movable feeding tube 8, and lighting lamps are arranged and connected to the bottom of the connecting ring so that the lighting lamps can provide illumination to the camera inside the annular dust cover.

[0011] Preferably, a feeding valve is connected to the upper part of the left side of the dustproof silo, and a feeding pipe is connected to the bottom of the feeding valve.

A movable discharge pipe 8 is slidably connected to the inner side of the limit groove 7. The outer side of the movable discharge pipe 8... Each side is connected to an annular dust cover 9. A dust cleaning trough 10 is connected to the lower edge of the inner side of the annular dust cover 9. A dust suction port 11 is opened on the inner side of the dust cleaning trough 10. A flexible pipe 12 is connected through the annular dust cover 9 on the right side of the dust cleaning trough 10. A connecting groove 13 is connected to the right side of the dust silo 4, and the other end of the flexible pipe 12 is connected to the left side of the connecting groove 13. A dust conveying pipe 14 is connected to the middle of the left side of the ash silo body 3, and the other end of the dust conveying pipe 14 is connected to the right side of the connecting groove 13.

[0027] The conveying module 5 can be a belt conveying system or a chain ash conveying hopper, etc. Its main function is to convey the ash material in the ash silo body 3 to the dust silo 4, and discharge the material through the discharge pipe formed by the connection of the fixed discharge pipe 6 and the movable discharge pipe 8.

[0028] A second mounting bracket 15 is connected to the top left side of the base plate 1. A water tank 16 is connected to the inside of the second mounting bracket 15. A water supply pipe 17 is connected to the top of the water tank 16. A water pump is installed on the water supply pipe 17 so that the second mounting bracket 15 fixes the water tank 16 to the top of the base plate 1 and draws water out of the water tank 16 through the water pump and the water supply pipe 17.

[0029] Spray pipes 18 are connected to both the front and rear sides of the dustproof silo 4. Spray nozzles 19 are connected to the bottom of the spray pipes 18. The left side of the spray pipes 18 is connected to the top of the water supply pipe 17, so that the water supply pipe 17 can draw water into the spray pipes 18 and spray water mist downward through the nozzles 19 to humidify the dust generated in the dustproof silo 4 and prevent it from overflowing.

[0030] A limiting ring 20 is connected to the inner side of the annular dust cover 9. Multiple cameras 21, preferably 2-3, are connected to the bottom of the limiting ring 20. The multiple cameras 21 are evenly distributed within the limiting ring 20, allowing the limiting ring 20 to move the cameras 21 vertically along with the rise and fall of the annular dust cover 9, providing full circumferential field of view. Specifically, the housing of the camera 21 can be snapped into the limiting ring 20 using a locking block, or fixed using threads or other fixing methods.

[0031] A connecting ring 22 is provided on the outside of the movable feeding pipe 8 and below the limiting ring 20. Multiple lighting lamps 23 are arranged at the bottom of the connecting ring 22 so that the lighting lamps 23 can provide illumination for the camera 21 inside the annular dust cover 9.

The other end of the feeding pipe 25 is connected to the right side of the conveying module 5, so that the feeding valve 24 can transport dust into the conveying module 5 through the feeding pipe 25.

[0033] Hydraulic cylinders 26 are connected to both sides of the top of the dustproof silo 4 via adapters. The movable end of the hydraulic cylinder 26 is connected to the top of the annular dustproof cover 9 via the adapter. The hydraulic cylinder 26 serves as the driving source and drives the annular dustproof cover 9 to rise and fall by extending and retracting its movable end.

[0034] A blower 27 is connected to the middle of the dust conveying pipe 14, so that the blower 27 serves as a driving source to generate negative pressure inside the dust conveying pipe 14, sucking up the overflowing dust and drawing it into the ash silo body 3.

[0035] Refer to the instruction manual appendix Figure 1-5 Working principle: When discharging ash, the hydraulic cylinder 26 is first controlled to move, causing the annular dust cover 9 to move downwards. The moving discharge pipe 8 also moves downwards and extends along the fixed discharge pipe 6. The annular dust cover 9 moves down to cover the discharge port of the tanker truck carrying the material. Then, the lighting lamp 23 provides illumination, and the camera 21 transmits the situation at the discharge port to the operator's computer, allowing the on-site operator to clearly understand the material discharge situation, realizing the visualization effect of the device during material discharge, and playing the role of visualizing ash discharge. During ash discharge, the annular dust cover 9 is used to cover the inlet of the tanker truck, which can effectively prevent dust from flying. At the same time, the exhaust fan 27 maintains negative pressure around the annular dust cover 9 to effectively extract the dust above the tanker truck, so that the dust can be effectively controlled and prevented from overflowing. At the same time, spray pipes 18 are set at the front and rear ends of the dust silo 4. The spray pipes 18, together with the atomizing nozzles 19, increase the humidity inside the dust silo, so that the residual dust cannot drift out of the dust silo 4, realizing dust control during ash discharge and playing the role of dust suppression.

[0036] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
