Description

Technical Field

[0001] The utility model relates to the field of ash transportation control devices, and particularly relates to a unit ash transportation control room. Background Technique

[0002] The flue gas generated by the combustion of a power plant boiler 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 lower part of the dust collector, and the collected particulate matter is called fly ash. In the conventional design, the maximum volume of the dust collector ash hopper can store the fly ash amount for 8 hours. Therefore, a power plant needs to set up a special fly ash storage to store fly ash to meet the storage requirements of 24 - 48 hours as required by the regulations and specifications. The fly ash storage is generally arranged in an area far from the boiler house, and the fly ash in the dust collector ash hopper is transported to the fly ash storage for storage by a pneumatic conveying method.

[0003] When the existing ash storage discharging device discharges ash, on - site operators cannot directly observe the storage amount inside the material truck, and it entirely depends on the experience of the staff for operation. This makes it easy for the material truck to discharge too much ash into the ash - transporting tank truck, causing ash overflow, or the discharge not reaching the inlet of the tank truck. Moreover, when discharging, fly ash spills and scatters, and the visibility of the working environment is poor, resulting in a greatly increased difficulty in discharging control.

[0004] Therefore, it is urgent to improve the unit ash transportation control room to achieve external visual observation and operation to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a unit ash transportation control room, which can effectively solve the problems that when discharging ash in the unit ash transportation, it is impossible to visualize, resulting in too much or too little discharging, and a high degree of human dependence.

In the middle of the left side of the ash silo body 3, a dust conveying pipe 14 is communicated. And the other end of the dust conveying pipe 14 is communicated with the right side of the communication groove 13.

[0027] The conveying module 5 can be a belt feeding system or a chain ash conveying hopper, etc. The main thing is that it can convey the ash in the ash silo body 3 to the dust-proof silo 4, and discharge the material through the discharging pipe formed by connecting the fixed discharging pipe 6 and the movable discharging pipe 8.

[0028] On the left side of the top of the bottom plate 1, a second mounting frame 15 is connected. Inside the second mounting frame 15, a water tank 16 is connected. On the top of the water tank 16, a water supply pipe 17 is communicated. A water pump is installed on the water supply pipe 17, so that the second mounting frame 15 fixes the water tank 16 on the top of the bottom plate 1, and the water in the water tank 16 is pumped out through the water pump and the water supply pipe 17.

[0029] On the front and back sides of the dust-proof silo 4, spray pipes 18 are connected. At the bottom of the spray pipes 18, spray heads 19 are arranged and communicated. The left side of the spray pipes 18 is communicated with the top of the water supply pipe 17, so that the water supply pipe 17 can pump the water into the spray pipes 18, and spray water mist downward through the spray heads 19 to humidify the dust generated in the dust-proof silo 4 and prevent it from overflowing.

[0030] Inside the annular dust-proof cover 9, a limiting ring 20 is connected. At the bottom of the limiting ring 20, a plurality of cameras 21 are connected, preferably 2 - 3; the plurality of cameras 21 are evenly arranged inside the limiting ring 20, so that the limiting ring 20 can drive the cameras 21 to move vertically following the lifting of the annular dust-proof cover 9, and the circumferential field of view is fully covered. Specifically, the housing of the camera 21 can be clamped with the limiting ring 20 through a clamping block, or fixed by other fixing methods such as threads.

[0031] Below the limiting ring 20 and on the outer side of the movable discharging pipe 8, a connecting ring 22 is arranged.

The annular dust-proof cover 9 is driven to move up and down by the telescopic movement of the movable ends of the hydraulic cylinders 26 with the hydraulic cylinders 26 as the driving source.

[0034] In the middle of the dust conveying pipe 14, an exhaust fan 27 is connected. With the exhaust fan 27 as the driving source, negative pressure is generated inside the dust conveying pipe 14 to suck the scattered dust and suck it into the ash bin body 3.

[0035] Refer to the attached Figures 1-5 , Working principle: When discharging ash materials, first control the hydraulic cylinder 26 to act, so that the annular dust-proof cover 9 moves downward, and the movable discharge pipe 8 also moves downward and extends along the fixed discharge pipe 6. The annular dust-proof cover 9 moves down to cover the discharge opening of the truck for pulling materials. Then, the lighting lamp 23 provides illumination, and at the same time, the camera 21 transmits the situation of the discharge opening to the operator's computer, enabling the on-site operator to clearly understand the discharging situation, realizing the visualization effect during the discharging of the device and playing the role of ash discharging visualization; when discharging ash, the annular dust-proof cover 9 is used to cover the inlet of the truck, which can effectively prevent dust from flying. At the same time, the exhaust fan 27 ensures negative pressure around the annular dust-proof cover 9 to effectively extract the dust floating above the truck, so that the dust can be effectively controlled and prevented from scattering. At the same time, spray pipes 18 are arranged at the front and rear ends of the dust-proof bin 4. The spray pipes 18 cooperate with the atomizing nozzles 19 to increase the humidity inside the dust-proof bin, so that the remaining dust cannot float out of the dust-proof bin 4, realizing the control of dust during ash discharging and playing the role of dust suppression.
