Description

Technical Field

[0001] This utility model specifically relates to a slag discharge device for a cold slag machine. Background Technology

[0002] The supercritical CFB boiler system's slag cooling system sends slag through a rear wall slag discharge pipe into a drum-type slag cooler. The slag cooler then transports the discharged slag to a chain bucket conveyor, which in turn conveys it to a bucket elevator outside the CFB boiler room. The bucket elevator then lifts and transports the slag to a slag storage silo, from where it is periodically transported by truck to ash disposal sites and users for comprehensive utilization.

[0003] In actual production, due to the combined effects of coal quality changes and deep peak shaving, the fuel in the furnace contains nearly 60% coal slime. The excessively fine high-temperature ash has excellent fluidity, which easily causes the ash in the slag pipe to flow by gravity. At the same time, the slag discharge pipe and expansion joint need to withstand the high temperature of gravity slag discharge. Under the combined action of thermal stress and alternating temperature load at the furnace slag discharge port, the slag discharge pipe is prone to overheating and expansion deformation, causing a large amount of ash to accumulate and block the cylinder of the slag cooler, causing it to trip and affecting the normal operation of the equipment. Therefore, we propose a slag discharge device for the slag cooler. Utility Model Content

[0004] The purpose of this utility model is to provide a slag discharge device for a cold slag machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slag discharge device for a cold slag machine, comprising:

[0007] A door panel is installed on the connecting pipe to adjust the flow inside the connecting pipe;

[0008] An expansion joint is detachably connected to the lower end of the slag discharge pipe;

[0009] An opening adjustment component is installed on the upper inner side of the slag discharge pipe to adjust the opening of one end of the connecting pipe.

[0010] Preferably, a furnace water-cooling assembly is provided on one side of the expansion joint, and the expansion joint and the furnace water-cooling assembly are fixed by a bracket.

[0011] Preferably, the opening adjustment assembly includes a controller, a sealing block, and an adjusting rod. The controller is fixed to the top of the slag discharge pipe, and the output end of the controller is provided with an adjusting rod. One end of the adjusting rod is connected to a sealing block that seals one end of the connecting pipe.

[0012] Preferably, the sealing block is conical.

[0013] Preferably, the controller is rotatably provided with an adjustment handle, and the adjustment handle and the adjustment rod are engaged by a threaded part.

[0014] Preferably, the connecting pipe has an inclined structure, and the length of the connecting pipe is less than the length of the slag discharge pipe.

[0015] Preferably, the expansion joint has a slag discharge outlet on one side wall.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention, by incorporating a controller, sealing block, and adjusting rod, prevents high-temperature ash from significantly affecting and deforming the ash discharge pipe and expansion joint. When the ash discharge pipe or expansion joint is exposed to high temperatures due to ash, this device can promptly adjust the amount of ash flowing into the inside of the ash discharge pipe and expansion joint, thereby reducing the transfer of ash temperature and minimizing the impact of high temperatures. Furthermore, by installing the ash discharge pipe and expansion joint near the furnace water-cooling assembly, the cooling capacity of the furnace water-cooling assembly can effectively reduce the temperature of the ash discharge pipe and expansion joint, ensuring a stable ash discharge output.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please refer to the figure. Figure 2 This utility model provides a technical solution: a slag discharge device for a cold slag machine, comprising:

[0023] Slag discharge pipe 4, a connecting pipe 3 is provided on one side of slag discharge pipe 4, and one end of the connecting pipe 3 is connected to slag discharge port 1;

[0024] Insertion gate 7 is installed on the connecting pipe 3 to adjust the on / off state of the inside of the connecting pipe 3;

[0025] This helps to prevent excessive high-temperature ash from flowing into the slag discharge pipe 4 and the inner side of the expansion joint 10.

[0026] Expansion joint 10 is detachably connected to the lower end of slag discharge pipe 4;

[0027] An opening adjustment component is installed on the upper inner side of the slag discharge pipe 4 to adjust the opening of one end of the connecting pipe 3;

[0028] This facilitates the adjustment of the high-temperature ash flowing into the inside of the ash discharge pipe 4, reducing the amount of ash flowing in when the temperature of the ash discharge pipe 4 is high.

[0029] In this embodiment, preferably, a furnace water-cooling component 5 is provided on one side of the expansion joint 10. The expansion joint 10 and the furnace water-cooling component 5 are fixed by a bracket, which facilitates the temperature transfer through the furnace water-cooling component 5 to reduce the temperature of the expansion joint 10 and the slag discharge pipe 4.

[0030] In this embodiment, preferably, the opening adjustment component includes a controller 6, a sealing block 8, and an adjusting rod 9. The controller 6 is fixed to the top of the slag discharge pipe 4, and the output end of the controller 6 is provided with an adjusting rod 9. One end of the adjusting rod 9 is connected to a sealing block 8 that closes one end of the connecting pipe 3, so as to adjust the position of the sealing block 8, thereby adjusting the opening of one end of the connecting pipe 3 and adjusting the amount of ash flowing into the inside of the slag discharge pipe 4.

[0031] In this embodiment, preferably, the sealing block 8 is conical, which facilitates better insertion into the inside of the flowing ash and slag, so as to adjust the opening of one end of the connecting pipe 3.

[0032] In this embodiment, preferably, the controller 6 is rotatably provided with an adjustment handle, and the adjustment handle and the adjustment rod 9 are engaged by a threaded part, which facilitates better adjustment of the up and down movement of the sealing block 8.

[0033] In this embodiment, preferably, the connecting pipe 3 is an inclined structure, and the length of the connecting pipe 3 is less than the length of the slag discharge pipe 4, so as to avoid the influence of high temperature ash and slag on the longer connecting pipe 3.

[0034] In this embodiment, preferably, a slag discharge outlet is provided on one side wall of the expansion joint 10 to facilitate slag discharge.

[0035] The working principle and usage process of this utility model are as follows: During use, the slag inside the slag cooler is discharged through the connecting pipe 3 and the slag discharge pipe 4. When the slag discharge pipe 4 or the expansion joint 10 is affected by the high temperature of the ash and slag and has a large amount of heat, the controller 6 can drive the adjusting rod 9 to move down, so that the adjusting rod 9 can drive the sealing block 8 to move. Thus, the sealing block 8 moves down slowly to adjust the opening of the lower end of the connecting pipe 3, reducing the amount of ash and slag entering the slag discharge pipe 4 and the expansion joint 10, thereby reducing the impact of high temperature on them. At the same time, the cooling capacity of the furnace water cooling component 5 will also be transferred to the expansion joint 10 and the slag discharge pipe 4 to reduce the temperature and prevent the slag discharge pipe 4 or the expansion joint 10 from deforming due to high temperature, which would affect the slag discharge effect.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
