[0016] 2. During operation of the present invention, tar will flow into the sealed water pool. At this time, the tar has just been heated by steam and has a relatively high temperature.

The mesh pipe is filled with hydrogen, so the gas inside the mesh pipe will expand and exert an upward thrust on the piston plate inside the sleeve, thereby causing the telescopic inner rod to push up the sealing plate, which will cause the pressure inside the sealed water pool to decrease, thereby having an air suction effect on the tar inside the coke oven gas blower body, making it easier for the tar to flow into the sealed water pool.

[0019] 5. In the process of gradually closing the lower air outlet of the present invention, the top air plate will slowly approach the lower air outlet by relying on the elastic structure between the spring and the fixed plate, so that the inside of the pneumatic telescopic rod will be blown up through the guide telescopic rod, so that the pneumatic telescopic rod will be extended and the connecting pipe will be unfolded to form a plane, thereby blocking the downward blowing of the air jet, thereby preventing the high-pressure steam from splashing tar and affecting the cleaning effect.

DETAILED DESCRIPTION

[0030] like Figure 1As shown, the present invention provides a technical solution: a slag and tar discharge device for a coke oven gas blower, comprising a coke oven gas blower body 1, a first sewage discharge ball valve 2 and a first sewage discharge pipe 3 installed on a slag and tar discharge port at the bottom of the coke oven gas blower body 1, a steam pipe 4 and a steam pipe ball valve 5 installed on a bypass of the first sewage discharge pipe 3, a second sewage discharge ball valve 6 and a second sewage discharge pipe 7 are installed in series with the first sewage discharge pipe 3, and the other end of the second sewage discharge pipe 7 is immersed in a sealed water pool 8, and the water pressure at the immersion depth is greater than the pressure in the coke oven gas blower body 1 to prevent gas leakage;

[0031] The specific operation is as follows, which has the characteristics of short production cycle, low manufacturing cost, high safety and reliability, high oil removal efficiency, simple and convenient operation, etc.

[0032] like Figures 2 to 9 As shown, a negative pressure component 9 is provided inside the sealed water pool 8, an injection component 10 is installed inside the coke oven gas blower body 1, and power components 11 are connected to the left and right sides of the injection component 10, and the end of the power component 11 away from the injection component 10 is connected to the transmission component 12, and the lower end of the transmission component 12 is connected to the lifting control component 13, and shielding components 14 are installed on the front and rear sides of the lower end of the coke oven gas blower body 1, and the upper end of the shielding component 14 is connected to the telescopic component 15.

[0033] like Figure 1 and Fig. 9 As shown, the negative pressure assembly 9 includes a cover plate 901, a sealing cover 902, a telescopic inner rod 903, a piston plate 904, a sleeve 905 and a mesh pipe 906, and the sealing cover 902 is embedded in the middle of the cover plate 901, the left and right sides of the lower end of the cover plate 901 are connected to the telescopic inner rod 903, and the lower end of the telescopic inner rod 903 is connected to the piston plate 904, the outside of the piston plate 904 is connected to the sleeve 905, and the lower end of the sleeve 905 is connected to the mesh pipe 906 on one side close to the central axis of the sealed water pool 8;

[0034] During operation, tar will flow into the sealed water tank 8. At this time, the tar has just been heated by steam and has a relatively high temperature. Therefore, when the tar enters the sealed water tank 8, it will heat the water. A mesh pipe 906 is provided at the outlet of the second sewage pipe 7, so the tar will instantly heat the mesh pipe 906. The mesh pipe 906 is filled with hydrogen, so the gas inside the mesh pipe 906 will expand and exert an upward thrust on the piston plate 904 inside the sleeve 905, so that the telescopic inner rod 903 drives the sealing plate 901 to push up, which will cause the pressure inside the sealed water tank 8 to decrease, thereby having an air suction effect on the tar inside the coke oven gas blower body 1, making it easier for the tar to flow into the sealed water tank 8.

[0035] like Figure 4As shown, the jet assembly 10 includes a supporting pipe 1001, an auxiliary closed ring 1002, a rotating pipe 1003 and a jet port 1004, and the auxiliary closed ring 1002 is installed at one end of the supporting pipe 1001, the rotating pipe 1003 is connected to the inside of the auxiliary closed ring 1002, and the lower end of the rotating pipe 1003 is connected to the jet port 1004, and the lower end of the supporting pipe 1001 is connected to the lower air outlet 16;

[0036] During the working process, the steam will drive the rotating turbine 1101, thereby driving the rotating shaft 1103 to rotate through the chain 1102, thereby driving the rotating tube 1003 to rotate, so that the jet port 1004 can rotate to spray steam, which is convenient for steam to clean the interior of the coke oven gas blower body 1 as a whole. At the same time, the direct steam spraying method can utilize the high pressure of the steam to facilitate the removal of tar inside the coke oven gas blower body 1.

[0037] like Figure 3 As shown, the power assembly 11 includes a rotating turbine 1101, a chain 1102, a rotating shaft 1103 and a connecting block 1104, and the end of the rotating turbine 1101 is connected to the chain 1102, the upper end of the chain 1102 is connected to the rotating shaft 1103, and the middle of the rotating shaft 1103 is connected to the connecting block 1104;

[0038] The rotating turbine 1101 drives the rotating shaft 1103 to rotate through the chain 1102, and the rotating shaft 1103 is connected to the rotating tube 1003 through the connecting block 1104, so the rotating shaft 1103 will drive the rotating tube 1003 that forms a rotating structure with the auxiliary closed ring 1002 bracket to rotate during the rotation process.

[0039] like Figure 5 As shown, the transmission assembly 12 includes a first gear 1201 and a second gear 1202 , and the lower end of the first gear 1201 is connected to the second gear 1202 .

[0040] like Figure 6 As shown, the lifting control assembly 13 includes a rotating rod 1301, a threaded rod 1302, a coil spring 1303 and an outer box 1304, and the lower end of the rotating rod 1301 is connected to the threaded rod 1302, the outer upper end of the threaded rod 1302 is connected to the coil spring 1303, and the outer part of the coil spring 1303 is connected to the outer box 1304, the lifting control assembly 13 also includes a support block 1305, a threaded sleeve 1306 and a closed cylinder 1307, and the outer middle of the threaded rod 1302 is rotatably connected to the support block 1305, the outer lower end of the threaded rod 1302 is connected to the threaded sleeve 1306, and the threaded sleeve 1306 is connected to the closed cylinder 1307 on the side close to the jet assembly 10;

[0041] While rotating and jetting, the chain 1102 will drive the threaded rod 1302 to rotate through the transmission assembly 12. At this time, the threaded rod 1302 will drive the threaded sleeve 1306 to descend, so that the closing tube 1307 will slowly block the lower air outlet 16. At this time, the correct air inside the support pipe 1001 will flow to the jet port 1004 as much as possible, so that the air pressure ejected from the jet port 1004 will be enhanced. As the tar inside the coke oven gas blower body 1 is cleaned, the lower the tar is, the longer it adheres and the more difficult it is to clean. The equipment is also pressurized during operation. Therefore, the present application will increase the steam pressure according to the change in cleaning difficulty, so that the equipment can continue to maintain a good cleaning effect.

[0042] like Figure 7 As shown, the shielding assembly 14 includes a shielding plate 1401, a connecting rotating block 1402, a pneumatic telescopic rod 1403 and a connecting pipe 1404, and the front and rear ends of the shielding plate 1401 are connected to the connecting rotating block 1402, the lower end of the connecting rotating block 1402 is connected to the pneumatic telescopic rod 1403, and the lower end of the pneumatic telescopic rod 1403 is connected to the connecting pipe 1404;

[0043] The gas inside the guide telescopic rod 1503 is squeezed into the pneumatic telescopic rod 1403 through the connecting pipe 1404, thereby pushing the connecting rotating block 1402 through the pneumatic telescopic rod 1403, so that the connecting rotating block 1402 forming a rotating structure with the shielding plate 1401 is unfolded, thereby blocking the downward jet from the jet outlet 1004.

[0044] like Figure 2 As shown, the telescopic assembly 15 includes a top air plate 1501, a spring 1502, a guide telescopic rod 1503 and a fixed plate 1504, and the lower end of the top air plate 1501 away from the jet assembly 10 is connected to the spring 1502, the upper end of the top air plate 1501 away from the jet assembly 10 is connected to the guide telescopic rod 1503, and the end of the guide telescopic rod 1503 away from the top air plate 1501 is connected to the fixed plate 1504;

[0045] As the lower air outlet 16 gradually closes, the top air plate 1501 will slowly approach the lower air outlet 16 by relying on the elastic structure between the spring 1502 and the fixed plate 1504, so that the inside of the pneumatic telescopic rod 1403 will be blown up through the guide telescopic rod 1503, thereby extending the pneumatic telescopic rod 1403 and expanding the connecting pipe 1404 to form a plane, thereby blocking the downward blowing of the air jet 1004, thereby preventing the high-pressure steam from splashing tar and affecting the cleaning effect.

[0046] Working principle: First, close the second sewage ball valve 6, open the steam pipe ball valve 5 and the first sewage ball valve 2, and let the high-temperature and high-pressure steam in the steam pipe 4 enter the coke oven gas blower body 1 through the first sewage pipe 3. After the high-temperature and high-pressure steam melts the tar that is easily attached to the coke oven gas blower body 1, close the steam pipe ball valve 5, open the second sewage ball valve 6, and let the melted tar and slag in the coke oven gas blower body 1 be discharged from the first sewage pipe 3 and the second sewage pipe 7 into the sealed water pool 8, so as to realize the slag and tar discharge system for the coke oven gas blower;

[0047] When steam enters the coke oven gas blower body 1, the steam in the first sewage pipe 3 enters the support pipe 1001, thereby driving the rotating turbine 1101 inside the support pipe 1001 to rotate, and then the rotating turbine 1101 drives the rotating shaft 1103 to rotate through the chain 1102, and the rotating shaft 1103 is connected to the rotating tube 1003 through the connecting block 1104, so the rotating shaft 1103 will drive the rotating tube 1003 that forms a rotating structure with the auxiliary closed ring 1002 bracket to rotate during the rotation process, so that the air jet 1004 rotates to clean the inner wall of the coke oven gas blower body 1. The air jet 1004 adopts a rotating method to facilitate cleaning of the internal surface of the entire coke oven gas blower body 1, and also facilitates the direct injection of high-pressure steam onto the inner wall of the coke oven gas blower body 1 to ensure the cleaning effect;

[0048] During the rotation of the turbine 1101, the first gear 1201 is also driven to rotate, thereby driving the second gear 1202 to rotate, so that the second gear 1202 drives the rotating rod 1301 to rotate, thereby driving the threaded rod 1302 threadedly connected with the threaded sleeve 1306 to rotate, so that the threaded sleeve 1306 descends and drives the closing cylinder 1307 to slowly block the lower air outlet 16. The lower air outlet 16 is slowly blocked, and at this time, the steam inside the support pipe 1001 is distributed to the air jet 1004 as much as possible, so that the steam ejected at the air jet 1004 is pressurized, thereby increasing the pressure of the steam ejected at the air jet 1004, so that the air jet 1004 can clean the relatively stubborn tar on the inner wall of the coke oven gas blower body 1, and the threaded rod 1302 continues to rotate until the closing cylinder 1307 completely closes the lower air outlet 16, and at the same time, the air pressure ejected from the air jet 1004 reaches the maximum, so that the high pressure of the air jet 1004 can clean the tar as much as possible;

[0049] The rotating rod 1301 and the threaded rod 1302 are directly connected and connected by friction, and the friction here is greater than the elastic force of the coil spring 1303. Therefore, when the closing cylinder 1307 drops to the bottom, the rotating rod 1301 can still rotate and will not affect the rotation of the air jet 1004. The turbine structure of the rotating turbine 1101 is subjected to high pressure impact, so the rotating turbine 1101 has a large rotation force, and the rotation force of the rotating turbine 1101 is much greater than the friction between the rotating rod 1301 and the threaded rod 1302.

[0050] When the lower air outlet 16 is blocked, the air pressure of the lower air outlet 16 will increase, but the amount of air ejected from the lower air outlet 16 will decrease, which will reduce the force of the steam on the top air plate 1501. At the same time, as the tar accumulates, the tar will also increase the outward push resistance of the top air plate 1501, which will make it easier for the top air plate 1501 to push the top air plate 1501 toward the lower air outlet 16 through the elastic force generated by the elastic structure formed between the spring 1502 and the fixed plate 1504, so that the guide telescopic rod 1503 will be pushed outward. The connecting rotating block 1402 is pushed by the connecting rotating block 1402 through the connecting pipe 1404, so that the connecting rotating block 1402 which forms a rotating structure with the shielding plate 1401 is unfolded, thereby shielding the downward jet from the jet port 1004, preventing the high-pressure steam ejected from the jet port 1004 from directly acting on the tar at the bottom of the coke oven gas blower body 1, thereby causing the tar to splash and affecting the cleaning effect;

[0051] At this time, until the high-pressure steam has finished cleaning the tar inside the coke oven gas blower body 1, the tar beating step is entered. First, the required valves are opened according to the above steps to make the pipeline conductive. At this time, because the steam stops, the rotating turbine 1101 is no longer subjected to the thrust of the steam. At this time, the rotating rod 1301 naturally loses the transmission force of the transmission component 12, so that the elastic potential energy of the coil spring 1303 can be released, driving the threaded rod 1302 to reverse. During the reversal process, the threaded rod 1302 will drive the sealing cylinder 1307 to rise, thereby opening the lower air outlet 16. At this time, the tar can flow into the sealed water pool 8 along the first sewage pipe 3 and the second sewage pipe 7. At this time, the tar has just been heated by steam and has a The higher temperature, so when the tar enters the sealed water pool 8, it will heat the water, and a mesh pipe 906 is provided at the outlet of the second sewage pipe 7, so the tar will instantly heat the mesh pipe 906, and the mesh pipe 906 is filled with hydrogen, so the gas inside the mesh pipe 906 will expand and exert an upward thrust on the piston plate 904 inside the sleeve 905, so that the telescopic inner rod 903 drives the sealing plate 901 to push up, which will cause the pressure inside the sealed water pool 8 to decrease, thereby exerting suction on the tar inside the coke oven gas blower body 1, so that all the tar flows into the sealed water pool 8, and the sealing cover 902 can facilitate the staff to take out the tar and water inside the sealed water pool 8.
