[0026] The present invention provides the following embodiments

[0032] The slag pushing assembly on the front side includes a mounting plate 15, which is fixedly mounted on one side of the top of the mounting frame 13, a driving hydraulic cylinder 16 is fixedly mounted on the mounting plate 15, a mounting rod 17 is fixedly mounted on the driving end of the driving hydraulic cylinder 16, one end of the mounting rod 17 is fixedly connected to an extrusion head 18, a mounting plate 2 19 is fixedly mounted on the top of the mounting frame 13, one end of a guide rod 20 is fixedly mounted on the side wall of the extrusion head 18, and the guide rod 20 is slidably connected to the mounting plate 2 19.

[0033] Preferably, the first crushing mechanism 4 includes a hydraulic jack 21, the fixed end of the hydraulic jack 21 is fixedly mounted on the inner wall of the rear guard plate 7, and the telescopic end of the hydraulic jack 21 is fixedly connected to a fixed bracket 22, a connecting sleeve 23 is fixedly mounted on the fixed bracket 22, one side of two slag pushing rods 24 is slidably connected to the inside of the connecting sleeve 23, and a plurality of positioning grooves 25 are embedded on one side of the slag pushing rod 24 located inside the connecting sleeve 23, and a plurality of locking screws 26 are symmetrically arranged on the positioning grooves 25 in an upper and lower manner, and the plurality of locking screws 26 are connected to the plurality of positioning grooves 25 in a one-to-one correspondence.

[0034] The working principle and beneficial effects of the above technical solution are:

[0035] The present invention provides a furnace bottom coke cleaning device for a thermal power plant by setting a protective mechanism 2, a slag pushing mechanism 3, a first crushing mechanism 4 and a second crushing mechanism 5. By setting the slag pushing mechanism 3 and the first crushing mechanism 4, in the initial stage of the formation of coke blocks at the furnace bottom, the slag pushing mechanism 3 is used to push the coke slag to avoid accumulation and aggregation. Secondly, the first crushing mechanism 4 loosens the formed coke blocks to make them collapse and break to complete the coke cleaning. At the same time, the second crushing mechanism 5 completes the processes of drilling, spraying water and splitting the coke blocks that have been bridged over a large area and cannot be pushed to complete the removal of the coke blocks. The above-mentioned coke cleaning operation is carried out inside the protective mechanism 2, which effectively avoids personal injury during the removal of the coke blocks.

[0036] The above-mentioned protective mechanism 2, the front guard plate 6, the rear guard plate 7 and the shield-type protective assembly arranged on both sides of the slag well of the boiler 1 can prevent the falling coke blocks from causing harm to the operators during the coke clearing operation. Secondly, the shield-type protective assembly includes a window 10, a soft connection hole 11 and a handle fixing ear 12. The window 10 can facilitate observation when clearing the coke inside the slag well, avoiding the operator from directly facing the coking process. At the same time, the soft connection hole 11 below the window 10 can facilitate the crushing mechanism to enter the slag well to drill, spray water and split the blocked coke blocks to complete the crushing of the coke blocks. The setting of the handle fixing ear 12 is convenient for installation and disassembly; at the same time, when the slag pushing assembly is working, the driving hydraulic cylinder 16 drives the installation rod 17 The reciprocating movement is realized so that the extrusion head 18 fixedly mounted at one end of the mounting rod 17 moves synchronously. The setting of the guide rod 20 prevents the extrusion head 18 from being damaged due to deviation during the process of pushing the coke block. The water-level slag pushing mechanism 3 symmetrically installed front and back on the top of the mounting frame 13 works together. In the initial stage of the formation of the coke block at the bottom of the furnace, the extrusion head 18 can be reasonably used to adopt a high-frequency pushing method to avoid the accumulation and aggregation of coke slag. The driving method of the extrusion head 18 adopted by the slag pushing mechanism 3 can also be replaced by a dry slag discharge device. When the high-temperature slag falls from the furnace into the slag discharge device through the slag well, the large slag blocks first fall on the grille for preliminary cooling, and then are broken into smaller particles by the horizontally moving toothed extrusion head 18 for subsequent transportation and processing.

[0037] The first crushing mechanism 4 set up as above loosens and removes the large-volume coke block after it has been formed. When the crushing process is carried out, the fixed bracket 22 fixedly connected to the telescopic end of the hydraulic jack 21 drives the connecting sleeve 23 to move horizontally, so that the two slag pushers 24 are installed in the connecting sleeve 23 through the locking screw 26, and the two slag pushers 24 can be adjusted in the connecting sleeve 23 to adapt to the removal of different blocked coke blocks. The mechanism acts on the side or bottom of the coke block to loosen the adhesion between the coke block and the wall. At the same time, the main body of the slag pusher 24 used here is made of a steel pipe with an outer diameter of 80mm and a thick wall of 5mm. Two slag pushers 24 of different lengths are connected to a suitable length, and the slag pushers 24 are connected through the connecting sleeve 23. If the coke block collapses and breaks after being loosened, the coke cleaning can be completed by continuing to squeeze through the extrusion head 18. The slag pusher 24 is used to automatically and continuously remove or push solid waste, thereby significantly improving work efficiency. Second, through the precise control of the driving mechanism, the slag pusher 24 can move according to a predetermined path and speed, thereby ensuring the accuracy of the operation. Third, the slag pusher 24 is usually made of wear-resistant and corrosion-resistant materials, and can operate stably for a long time in a harsh working environment. Fourth, the structure of the slag pusher 24 is relatively simple, and it is easy to maintain and replace damaged parts.

[0038] The above-mentioned furnace bottom coke cleaning device for thermal power plants uses mechanical operations to replace manual operation tools to perform furnace bottom coke cleaning operations, which greatly improves the efficiency of coke block cleaning, reduces the consumption of manpower during the operation, and greatly reduces labor costs; at the same time, the protective mechanism 2 provided in conjunction can prevent operators from being injured during coke cleaning operations, effectively ensuring the safety of the unit and improving safety. At the same time, the device can effectively ensure the efficient and safe operation of furnace bottom coke cleaning in thermal power plants. By using the slag pushing mechanism 3 and the first crushing mechanism 4, the problem of coke slag blockage at the furnace bottom can be effectively solved, the operating efficiency and safety of the boiler 1 can be improved, and a long-term mechanism for coke cleaning work can be realized. The boiler 1 can be cleaned and maintained regularly to ensure that the boiler 1 is always in a good operating state.

[0039] Example 2

[0040] On the basis of Example 1, Figure 5As shown, the second crushing mechanism 5 includes a box body 27, a plurality of supporting legs 28 are fixedly installed on the bottom circumference of the box body 27, a driving box 29 is fixedly installed on the bottom of the box body 27, a forward and reverse driving motor 30 is fixedly installed on the bottom of the driving box 29, a threaded rod 31 is fixedly installed on the output end of the forward and reverse driving motor 30, and the top of the threaded rod 31 is rotatably connected to the top of the driving box 29, a threaded slider 32 is threadedly connected to the threaded rod 31, and the threaded slider 32 slides through the side wall of the driving box 29, a fixing plate 2 33 is fixedly installed on one side of the threaded slider 32, a drilling assembly and a splitting assembly are installed on the upper and lower sides of the fixing plate 2 33, and a water tank 34 is fixedly installed on the top of the driving box 29.

[0041] Preferably, the drilling assembly includes a first electric push rod 35, which is embedded in the fixed plate 2 33, and the telescopic end of the first electric push rod 35 is fixedly installed with a connecting piece 36, a sliding rod 37 is fixedly installed on the side wall of the fixed plate 2 33, and the bottom of the connecting piece 36 is slidably connected to the sliding rod 37, a pneumatic drill 38 is fixedly installed in the connecting piece 36, and the upper ends of two telescopic rods 39 are respectively hinged on the front and rear side walls of the pneumatic drill 38, and the lower ends of the telescopic rods 39 are hinged on the side walls of the fixed plate 2 33, a high temperature resistant hose 40 is fixedly installed on the pneumatic drill 38, and the water inlet of the high temperature resistant hose 40 is connected to the water outlet of the water tank 34 through a water pump 41, and the water outlet of the high temperature resistant hose 40 is connected to a high pressure nozzle 42.

[0042] Preferably, the splitting assembly includes a second electric push rod 43, the second electric push rod 43 is embedded in the fixed plate 33, the fixed seat 44 is fixedly installed on the telescopic end of the second electric push rod 43, the bottom of the locking hoop 45 is fixedly installed on the bottom of the fixed seat 44 through a hinge rod 48, one side of the locking hoop 45 is fixedly connected to the side wall of the fixed seat 44 through a plurality of two springs 46, the tail of the splitting gun 47 is embedded in the locking hoop 45, the hydraulic drive box 49 is fixedly installed on the side wall of the drive box 29, and the hydraulic drive box 49 is connected to the splitting gun 47 through a high-pressure oil pipe 50.

[0043] The working principle and beneficial effects of the above technical solution are:

[0044] The second crushing mechanism 5 is arranged in a furnace bottom coke cleaning device for a thermal power plant. When the slag pit coke block has a large area of ​​bridging and cannot be pushed, the mechanism performs the crushing operation. First, a part is selected on the coke block, and the driving box 29 arranged in the box body 27 provides power to drive the adjustment of the working position of the drilling assembly and the splitting assembly installed on the second fixed plate 33. The forward and reverse driving motor 30 in the driving box 29 starts to run, driving the threaded rod 31 fixedly installed on the output shaft of the forward and reverse driving motor 30 to achieve forward and reverse rotation, and at the same time, the threaded slider 32 threadedly connected to the threaded rod 31 is moved up and down, driving the second fixed plate 33 fixedly installed on the threaded slider 32 to move up and down, and the adjustment of the working position of the drilling assembly and the splitting assembly is achieved.

[0045] When the drilling process is performed, the working position of the drilling assembly is first adjusted to the same height as the soft connection hole 11. At this time, the first electric push rod 35 drives the pneumatic drill 38 connected by the connecting piece 36 to perform drilling operations on the surface of the coke block through telescopic movement (the pneumatic drill 38 is matched with a suitable drill rod). At the same time, when the connecting piece 36 moves horizontally with the pneumatic drill 38, the connecting piece 36 is slidably connected to the sliding rod 37 to guide the pneumatic drill 38 when drilling. At the same time, it can provide support for the pneumatic drill 38 during the drilling operation to avoid the drilling operation being deviated due to the shaking of the drilling pneumatic drill 38. At the same time, during the drilling process, the drill rod of the pneumatic drill 38 should be taken out regularly, and the water pump 41 will transport the water source in the water tank 34 fixedly installed on the top of the drive box 29 to the high-pressure nozzle 42 through the high-temperature resistant hose 40, and the coke block in the hole will be cooled by spraying water with a small flow rate of the high-pressure nozzle 42 (with an extended nozzle made of stainless steel) to ensure that the drill rod is not adhered. Through continuous operation, at least three holes with a spacing of 100-300mm are drilled in this way. After the drilling assembly completes the operation, the first electric push rod 35 drives the pneumatic drill 38 to disengage from the protective mechanism 2 and restore the original initial working position; then the forward and reverse drive motor 30 drives the fixed plate 2 33, so that the splitting assembly is at the same height of the soft connection hole 11, and at this time, the extension of the second electric push rod 43 drives the splitting gun 47 fixedly installed on the mounting seat to enter the protective mechanism 2, so that the splitting gun 47 is placed in the corresponding drilled hole (the parts other than the head of the splitting gun 47 are equipped with thermal insulation protection), and the splitting gun 47 is fixedly installed in the drive box 29. The hydraulic drive box 49 on the side wall is opened, so that the hydraulic drive box 49 transmits high-pressure oil to the splitting gun 47 through the high-pressure oil pipe 50, thereby driving the splitting gun 47 to complete the crushing of the coke block within a small range of the pre-drilled hole. This method is used for continuous operation, and the water level range of all drilling and splitting is gradually expanded to complete the crushing of the entire coke block. As each process of drilling, water spraying, and splitting is carried out, the air drill 38, the water spraying device, and the splitting gun 47 all pass through the shield-type protection component and then extend into the slag pit wall or the slag machine, effectively preventing the falling red-hot coke blocks from causing harm to people; at the same time, the splitting gun 47 connected by the locking hoop 45 and the hinged rod 48 is fixedly installed on the fixed seat 44, and one side of the locking hoop 45 is connected to the fixed seat 44 by two springs 46. The above can better avoid the splitting gun 47 from collapsing and injuring people during the operation of the splitting gun 47 after the coke block is broken. This mechanism effectively improves the stability and reliability of the operation of the furnace bottom coke cleaning device used in thermal power plants.
