Description

Technical Field

[0001] The invention relates to the technical field of coking, in particular to a coke oven smoke collecting device. Background Art

[0002] A coke oven is a device used to produce coke. Its main function is to dry distill coal at high temperatures and decompose it into products such as coke, coal gas and tar. A coke oven usually consists of a combustion chamber, a carbonization chamber, a heat storage chamber and a flue. The combustion chamber is the core part, providing a high-temperature environment for coal dry distillation. In addition, the coke oven's ancillary equipment includes heating equipment and mechanical devices, which are responsible for operations such as coal loading, coking and quenching. The lifespan of a modern coke oven can generally reach 25 to 30 years. Good operation and maintenance are the key to extending its lifespan.

[0003] In the current existing technology, during coking production, after the coke side furnace door of the coke oven is opened, smoke and dust overflow from the top of the furnace door, affecting the environment. There are no professional and effective collection facilities at the location of the smoke and dust, thus causing unorganized emissions and environmental problems, affecting the normal production of the coke oven. Summary of the invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the damage to the pipeline caused by tar and impurities in the smoke when exhausting the smoke from the coke oven.

[0005] In order to solve the above technical problems, the present invention provides a coke oven smoke collection device, characterized in that it comprises a dust removal pipeline, a dust collecting hood is fixedly installed at the bottom end of the dust removal pipeline, a dust guide device is arranged on the inner wall of the dust collecting hood, a smoke detector is arranged inside the dust guide device, the dust collecting hood covers the top of the furnace door, a pneumatic butterfly valve is fixedly installed on the outer wall of the dust removal pipeline, a controller is fixedly installed on the outer wall of the pneumatic butterfly valve, the controller and the smoke detector are connected by a wire, one end of the wire is connected to the smoke detector, an operation box is fixedly installed on the outer wall of the dust removal pipeline, a dust screening mechanism is arranged inside the operation box, the dust screening mechanism comprises a dust filter cotton plate, the dust screening mechanism is used to drive the dust filter cotton plate to remove impurities and tar from the smoke entering the dust removal pipeline, and a separation mechanism is arranged inside the operation box, the separation mechanism is used to separate the impurities and tar screened out by the dust screening mechanism;

[0006] When the furnace door is opened, the smoke detector in the dust guide device captures the smoke, and then the controller controls the pneumatic butterfly valve to open, and then the dust guide device guides the smoke emitted from the furnace door into the dust removal pipe. When the smoke flows into the dust removal pipe through the guide of the dust guide device, the dust screening mechanism drives the dust filter cotton plate to filter the smoke, and filters out impurities and tar in the smoke from the smoke, preventing the impurities and tar in the smoke from adhering to the inner wall of the dust removal pipe when the smoke flows in the dust removal pipe, thereby causing accumulation and blockage, affecting the subsequent smoke circulation, and then passing through The filtered flue gas will flow out along the dust removal pipe. By connecting a smoke extinguishing device at one end of the dust removal pipe, the flue gas flowing out of the dust removal pipe will enter the smoke extinguishing device for smoke removal. When the smoke removal operation is completed, the dust screening mechanism drives the dust filter cotton board back to the operation box, and the separation mechanism in the operation box separates and collects the impurities and tar filtered off the dust filter cotton board, thereby recovering the tar and facilitating the subsequent utilization of the tar. When the separation mechanism finishes the operation, the dust screening mechanism drives the dust filter cotton board back to the dust removal pipe, which is convenient for the next smoke filtering operation.

[0007] In one embodiment of the present invention, the dust screening mechanism also includes a motor, a gear is fixedly installed on the output end of the motor, and a fitting block is fixedly installed on the outer wall of the dust filter cotton plate, the outer walls of the dust filter cotton plate and the fitting block are slidably connected to the inner wall of the dust removal pipe, and a moving plate rod is fixedly installed on one end of the fitting block, the top of the moving plate rod is slidably connected to the top of the inner wall of the working box, the teeth on the moving plate rod are meshed with the teeth of the gear, and the height of the fitting block is higher than the height of the dust filter cotton plate. When the smoke and dust completely pass through the dust filter cotton plate, the motor drives the gear to rotate, and when the gear rotates, the moving plate rod is driven back through the meshing transmission, thereby moving the dust filter cotton plate from the dust removal pipe to the working box through the fitting block, thereby playing the role of moving the dust filter cotton plate, and the fitting block is arranged so that when the smoke and dust flow, the smoke and dust will not flow into the working box, thereby playing the role of limiting the flow of smoke and dust.

[0008] In one embodiment of the present invention, a support plate and a separation box are fixedly installed on the inner wall of the working box, and the separation box is placed above one side of the support plate, and an inner box is fixedly installed on the inner wall of the separation box, and a rectangular block is slidably connected to the top inner wall of the inner box, and a scraper is fixedly installed on the top of the rectangular block, and a plurality of vertical rods are fixedly installed on the bottom of the scraper, and a plurality of return springs are arranged between the bottom of the scraper and the inner wall of the inner box, and the plurality of return springs are respectively arranged on the outside of the plurality of vertical rods, and one side of the scraper is arranged as an inclined sliding surface, and a limited slag block is symmetrically fixedly installed on the inclined sliding surface of the scraper, and pressure blocks are symmetrically fixedly installed on both sides of the scraper, and the top ends of the two pressure blocks can be slidably connected to the bottom of the fitting block, and a slag dropping opening is opened between the outer wall of the inner box and the inner wall of the separation box, and the slag dropping opening is arranged on one side of the scraper, and when the dust filter cotton plate moves into the working box, The engaging block will squeeze the knife block to move downward. When the knife block moves downward, it drives the moment block to move downward in the inner box through the scraper, so that when the engaging block moves into the working box, the scraper will not block the moving path of the engaging block. When the engaging block completely passes the scraper, the knife block loses its limit, and the scraper will be reset under the elastic force of the reset spring, thereby scraping the bottom of the dust filter cotton plate at one end of the engaging block, thereby scraping out impurities and tar attached to the bottom of the dust filter cotton plate. At the same time, scraping out impurities and tar attached to the bottom of the dust filter cotton plate is also beneficial to the subsequent dust filter cotton plate to filter smoke, and prevents the filter holes of the dust filter cotton plate from being blocked. When impurities and tar are scraped off, through the limit of the slag limit block, the scraped impurities and tar will enter the separation box from the slag outlet, thereby scraping off impurities and tar.

[0009] In one embodiment of the present invention, the inner wall of the inner box is slidably connected with an oil filter plate. When impurities and tar fall from the residue outlet, the impurities and tar will fall on the oil filter plate, which serves as a placement, making it easier for the separation mechanism to separate the two.

[0010] In one embodiment of the present invention, rectangular plates are symmetrically fixedly installed at both ends of the oil filter plate, sliding shafts are fixedly installed at the bottom of the two rectangular plates, the outer walls of the two sliding shafts are slidably connected to the inner wall of the separation box, and return plate springs are arranged between the bottoms of the two rectangular plates and the inner wall of the separation box. The two return plate springs are respectively placed on the outside of the two sliding shafts. Impurities and tar continuously fall on the oil filter plate, and the impurities and tar will squeeze the oil filter plate downward due to their weight. When the oil filter plate moves downward, it will squeeze the return plate spring downward. When the oil filter plate moves to a certain extent, the separation mechanism separates the impurities and tar accumulated inside it, thereby playing a role in gathering slag.

[0011] In one embodiment of the present invention, the separation mechanism includes a thrust rod, the teeth of the thrust rod are meshed with the gear, and push shafts are fixedly installed on both sides of the thrust rod. The inner walls of the separation box and the inner box are slidably connected with an oil squeezing plate, and a push rod is symmetrically fixedly installed on one side of the oil squeezing plate. The outer walls of the two push rods are respectively slidably connected to the inner walls of the two push shafts, and pressure springs are symmetrically arranged between one side of the oil squeezing plate and one side of the two push shafts. The two pressure springs are respectively placed on the outsides of the two push rods, and the bottom of the thrust rod is slidably connected to the top of the support plate. When the oil filter plate moves down to a certain extent, the oil squeezing plate will lose its limit, and the thrust rod is driven to move while the gear drives the thrust rod to rotate. When moving, the thrust rod drives the push shaft to move. Through the setting of the pressure spring and the push rod, when one side of the oil squeezing plate loses its limit, the push shaft moves and drives the oil squeezing plate to move toward the oil filter plate. When the oil squeezing plate moves, it pushes the impurities and tar on the oil filter plate, and the impurities and tar are separated by pushing, thereby playing the role of pushing the impurities and tar.

[0012] In one embodiment of the present invention, a shift frame is slidably connected to the top of the support plate, and the shift frame is placed at the bottom of the separation box. A slag blocking plate is arranged on one side of the separation box, and the outer wall of the slag blocking plate can fit with the outer wall of the separation box. A limiting plate is fixedly installed on the inner wall of the working box, and a slag dropping groove is formed between one side of the support plate and the limiting plate. Both ends of the slag blocking plate are slidably connected to the inner wall of the limiting plate, and a strong pressure spring is symmetrically arranged between the outer side of the slag blocking plate and the inner wall of the limiting plate. One end of the shift frame is fixedly connected to the bottom of the slag blocking plate. Through the limitation of the slag blocking plate, impurities and tar will be squeezed by the oil filter plate, so that the tar will be squeezed out of the impurities and finally enter the bottom of the separation box through the filter holes on the oil filter plate. When the thrust rod moves to the moving degree, one end of the thrust rod will push the shift frame to move, so that the shift frame squeezes the strong pressure spring to open, and the impurities can be pushed out from the top of the oil filter plate by the push of the oil squeezing plate, thereby separating the impurities and tar.

[0013] In one embodiment of the present invention, a slag sliding ramp is provided at the bottom of the inner wall of the working box, one end of the slag sliding ramp is placed directly below the slag dropping groove, and the top of the slag sliding ramp is an inclined sliding surface. When impurities are pushed out by the oil squeezing plate, the impurities will pass through the slag dropping groove and fall onto the slag sliding ramp for impurity placement. The inclined sliding surface on the top of the slag sliding ramp is provided to facilitate the flow of impurities.

[0014] In one embodiment of the present invention, an oil flow pipe is fixedly installed at the bottom of the separation box, and a slag box is slidably connected to the other end of the slag sliding ramp. One end of the slag discharge box and one end of the oil flow pipe are both placed outside the working box. When tar enters the bottom of the separation box, the separated tar can be taken out by connecting a collecting device to the oil flow pipe, and the impurities sliding down from the top of the slag sliding ramp can be taken out from the slag discharge box by connecting a slag flowing device to the slag discharge box, thereby removing the tar impurities.

[0015] In one embodiment of the present invention, the outer wall of the slag sliding platform is slidingly connected to the inner wall of the working box, and a plurality of screening springs are arranged between the bottom of the slag sliding platform and the bottom of the inner wall of the working box. The bottom of the inner wall of the working box is rotatably connected with a cam shaft, and the cam shaft is placed in the middle position of the bottom of the slag sliding platform. One end of the cam shaft and the output end of the motor are fixedly installed with a transmission shaft, and the outer walls of the two transmission shafts are transmission-connected with a belt. When the motor rotates, the motor also drives the cam shaft through the transmission shaft and the belt. When the cam shaft rotates, the cam shaft pushes the slag sliding platform to move upward in the working box, and the slag sliding platform is continuously reset by the continuous push of the cam shaft and the screening springs, so that the slag sliding platform vibrates in the working box, thereby vibrating the impurities on the slag sliding platform and sliding them off, preventing the impurities from accumulating on the top of the slag sliding platform and affecting the slag sliding effect, thereby playing the role of vibrating the slag.

[0016] The above technical solution of the present invention has the following advantages compared with the prior art:

[0017] The coke oven smoke collection device described in the present invention captures the smoke through a smoke detector, a controller controls the pneumatic butterfly valve to open, the dust guiding device guides the smoke emitted from the furnace door into the dust removal pipe, and the dust screening mechanism drives the dust filter cotton plate to filter the smoke, and impurities and tar in the smoke are filtered out from the smoke, so as to prevent the impurities and tar in the smoke from adhering to the inner wall of the dust removal pipe when the smoke flows in the dust removal pipe, thereby causing accumulation and blockage, and affecting the subsequent smoke circulation. When the smoke removal operation is completed, the dust screening mechanism drives the dust filter cotton plate to return to the operation box, and the separation mechanism in the operation box separates and collects the impurities and tar filtered on the dust filter cotton plate, so as to recover the tar.

[0018] The coke oven smoke collection device described in the present invention moves the dust filter cotton plate into the working box, and the scraper scrapes the bottom of the dust filter cotton plate at one end of the fitting block, thereby scraping out impurities and tar attached to the bottom of the dust filter cotton plate. At the same time, scraping out impurities and tar attached to the bottom of the dust filter cotton plate is also beneficial to the subsequent dust filter cotton plate to filter the smoke, and prevents the filter holes of the dust filter cotton plate from being blocked. When the impurities and tar are scraped off, the impurities and tar scraped off will enter the separation box from the slag outlet through the limiting position of the slag limiting block, thereby playing the role of scraping off the impurities and tar.

[0019] The coke oven smoke collection device described in the present invention has impurities and tar continuously falling on the oil filter plate. The impurities and tar will squeeze the oil filter plate downward due to their weight. When the oil filter plate moves downward, it will squeeze the return plate spring downward. When the oil filter plate moves to a certain extent, the separation mechanism separates the impurities and tar accumulated inside it, thereby playing a slag gathering role.

[0020] The coke oven smoke collection device described in the present invention has the following characteristics: when the oil filter plate moves down to a certain extent, the oil squeezing plate will lose its limit, and the motor drives the rotation while the gear drives the thrust rod to move, and the thrust rod drives the push shaft to move during the movement. Through the arrangement of the pressure-bearing spring and the push rod, when one side of the oil squeezing plate loses its limit, the push shaft moves and drives the oil squeezing plate to move toward the oil filter plate. When the oil squeezing plate moves, it pushes the impurities and tar on the oil filter plate, and the impurities and tar are separated by pushing, thereby playing the role of pushing the impurities and tar.

[0021] The coke oven smoke collection device described in the present invention has the following advantages: when the oil squeezing plate pushes the impurities and tar on the oil filter plate, the impurities and tar will be squeezed by the oil filter plate through the limitation of the slag blocking plate, so that the tar will be squeezed out from the impurities and finally enter the bottom of the separation box through the filter holes on the oil filter plate; when the thrust rod moves to the moving degree, one end of the thrust rod will push the shift frame to move, so that the shift frame squeezes the high-pressure spring to open, and the impurities can be pushed out from the top of the oil filter plate through the push of the oil squeezing plate, thereby separating the impurities and tar.

DETAILED DESCRIPTION

[0034] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0035] like Figures 1 to 10 As shown, a coke oven smoke collection device of the present invention comprises a dust removal pipe 5, a dust collecting hood 1 is fixedly installed at the bottom end of the dust removal pipe 5, a dust guide device 101 is arranged on the inner wall of the dust collecting hood 1, a smoke detector is arranged inside the dust guide device 101, the dust collecting hood 1 covers the top of the furnace door, a pneumatic butterfly valve 3 is fixedly installed on the outer wall of the dust removal pipe 5, a controller 4 is fixedly installed on the outer wall of the pneumatic butterfly valve 3, the controller 4 and the smoke detector are connected through a wire, an operating box 2 is fixedly installed on the outer wall of the dust removal pipe 5, a dust screening mechanism is arranged inside the operating box 2, the dust screening mechanism comprises a dust filter cotton plate 6, the dust screening mechanism is used to drive the dust filter cotton plate 6 to remove impurities and tar from the smoke entering the dust removal pipe 5, and a separation mechanism is arranged inside the operating box 2, the separation mechanism is used to separate the impurities and tar screened out by the dust screening mechanism;

[0036] During coking production, when the coke side door of the coke oven is opened, smoke and dust overflow from the top of the door, affecting the environment and affecting the normal production of the coke oven;

[0037] A smoke extinguishing device is connected to one end of the dust removal duct 5, and the smoke extinguishing device is used to break up the gas filtered by the dust filter cotton plate 6. When the furnace door is opened, the smoke is captured by the smoke detector in the dust guide device 101, and then the controller 4 controls the pneumatic butterfly valve 3 to open, and then the dust guide device 101 guides the smoke emitted from the furnace door into the dust removal duct 5. When the smoke flows into the dust removal duct 5 through the guide of the dust guide device 101, the dust screening mechanism drives the dust filter cotton plate 6 to filter the smoke, and filters out impurities and tar in the smoke from the smoke, so as to prevent the impurities and tar in the smoke from adhering to the inner wall of the dust removal duct 5 when the smoke flows in the dust removal duct 5, thereby causing accumulation and blockage, which affects The subsequent smoke and dust circulation, and then the filtered smoke will flow out along the dust removal pipe 5, and the smoke flowing out of the dust removal pipe 5 will enter the smoke extinguishing device for smoke removal operation. When the smoke removal operation is completed, the dust screening mechanism drives the dust filter cotton plate 6 back to the operation box 2, and the separation mechanism in the operation box 2 separates and collects the impurities and tar filtered out from the dust filter cotton plate 6, so as to recover the tar and facilitate the subsequent utilization of the tar. When the separation mechanism is finished, the dust screening mechanism drives the dust filter cotton plate 6 back to the dust removal pipe 5, so as to facilitate the next filtering operation of the smoke. At this point, the problem of smoke and dust overflowing from the top of the furnace door after the coke side furnace door of the coke oven is opened and affecting the environment and the normal production of the coke oven is solved in the coking production.

[0038] like Figures 3 to 6 As shown, the dust screening mechanism also includes a motor 7, a gear 701 is fixedly installed on the output end of the motor 7, a fitting block 601 is fixedly installed on the outer wall of the dust filter cotton plate 6, the outer walls of the dust filter cotton plate 6 and the fitting block 601 are slidably connected to the inner wall of the dust removal pipe 5, and a shifting plate rod 602 is fixedly installed on one end of the fitting block 601, the top of the shifting plate rod 602 is slidably connected to the top of the inner wall of the working box 2, the teeth on the shifting plate rod 602 are meshed with the teeth of the gear 701, and the height of the fitting block 601 is higher than the height of the dust filter cotton plate 6;

[0039] When the smoke has completely passed through the dust filter cotton plate 6, the motor 7 drives the gear 701 to rotate. When the gear 701 rotates, it drives the shifting plate rod 602 to move back through the meshing transmission, so that the dust filter cotton plate 6 is moved from the dust removal pipe 5 to the working box 2 through the fitting block 601, which plays the role of moving the dust filter cotton plate 6, so that the separation mechanism in the subsequent working box 2 can extract the tar and impurities attached to the dust filter cotton plate 6. The fitting block 601 is set to prevent the smoke from flowing into the working box 2 when the smoke flows, so as to limit the flow of the smoke. Setting the fitting block 601 higher than the height of the dust filter cotton plate 6 can prevent the tar and impurities attached to the bottom of the dust filter cotton plate 6 from being scraped onto the dust removal pipe 5 and the working box 2 when the dust filter cotton plate 6 moves to the working box 2.

[0040] like Figures 7 to 9As shown, a support plate 201 and a separation box 8 are fixedly installed on the inner wall of the work box 2. The separation box 8 is placed above one side of the support plate 201. An inner box 805 is fixedly installed on the inner wall of the separation box 8. A rectangular block 803 is slidably connected to the top inner wall of the inner box 805. A scraper 802 is fixedly installed on the top of the rectangular block 803. A plurality of vertical rods 8022 are fixedly installed on the bottom of the scraper 802. A plurality of return springs 804 are arranged between the bottom of the scraper 802 and the inner wall of the inner box 805. A plurality of return springs 804 are respectively placed outside a plurality of vertical rods 8022, one side of the scraper 802 is set as an inclined sliding surface, the inclined sliding surface of the scraper 802 is symmetrically fixedly installed with a limited slag block 8021, and the two sides of the scraper 802 are symmetrically fixedly installed with a pressure block 801, and the tops of the two pressure blocks 801 can be slidably connected to the bottom of the fitting block 601, and a slag drop opening is opened between the outer wall of the inner box 805 and the inner wall of the separation box 8, and the slag drop opening is placed on one side of the scraper 802;

[0041] Since the height of the mating block 601 is higher than the height of the dust filter cotton plate 6, when the dust filter cotton plate 6 moves into the working box 2, the mating block 601 will squeeze the pressure knife block 801 to move downward. When the pressure knife block 801 moves downward, the scraper 802 drives the moment block 803 to move downward in the inner box 805, so that when the mating block 601 moves into the working box 2, the scraper 802 will not block the moving path of the mating block 601. When the mating block 601 completely passes the scraper 802, the pressure knife block 801 loses its limit, and the scraper 802 will be reset. The spring 804 is driven to reset by the elastic force of the spring, thereby scraping the bottom of the dust filter cotton plate 6 at one end of the fitting block 601, thereby scraping out the impurities and tar attached to the bottom of the dust filter cotton plate 6. At the same time, scraping out the impurities and tar attached to the bottom of the dust filter cotton plate 6 is also beneficial to the subsequent dust filter cotton plate 6 to filter the smoke, and prevents the filter holes of the dust filter cotton plate 6 from being blocked. When the impurities and tar are scraped off, the impurities and tar scraped off will enter the separation box 8 from the slag outlet through the limiting slag block 8021, thereby scraping off the impurities and tar.

[0042] like Figures 7 and 8 As shown, the inner wall of the inner box 805 is slidably connected with an oil filter plate 806;

[0043] When impurities and tar fall from the slag outlet, they will fall on the oil filter plate 806, which will serve as a placement, making it easier for the separation mechanism to separate the two.

[0044] like Figures 7 and 8As shown, the two ends of the oil filter plate 806 are symmetrically fixed with rectangular plates 808, the bottoms of the two rectangular plates 808 are fixed with sliding shafts 809, the outer walls of the two sliding shafts 809 are slidably connected with the inner wall of the separation box 8, and return springs 807 are arranged between the bottoms of the two rectangular plates 808 and the inner wall of the separation box 8, and the two return springs 807 are respectively placed outside the two sliding shafts 809;

[0045] Since the amount of impurities and tar in the primary smoke is small, the impurities and tar continuously fall on the oil filter plate 806. The weight of the impurities and tar will squeeze the oil filter plate 806 downward, and the oil filter plate 806 will squeeze the return plate spring 807 downward when moving downward. When the oil filter plate 806 moves to a certain extent, the separation mechanism separates the impurities and tar accumulated inside it, thereby playing a role in gathering slag.

[0046] like Figures 5 and 6 As shown, the separation mechanism includes a thrust rod 603, the teeth of the thrust rod 603 are meshed with the gear 701, and push shafts 604 are fixedly installed on both sides of the thrust rod 603. The inner walls of the separation box 8 and the inner box 805 are slidably connected with oil squeezing plates 607, and one side of the oil squeezing plate 607 is symmetrically fixedly installed with a thrust rod 605. The outer walls of the two thrust rods 605 are respectively slidably connected with the inner walls of the two push shafts 604, and pressure springs 606 are symmetrically arranged between one side of the oil squeezing plate 607 and one side of the two push shafts 604. The two pressure springs 606 are respectively placed on the outside of the two thrust rods 605, and the bottom of the thrust rod 603 is slidably connected with the top of the support plate 201.

[0047] When the oil filter plate 806 moves down to a certain extent, the oil squeezing plate 607 will lose its limit, and the gear 701 drives the thrust rod 603 to move while the motor 7 drives it to rotate. When moving, the thrust rod 603 drives the push shaft 604 to move. Through the setting of the pressure spring 606 and the push rod 605, when one side of the oil squeezing plate 607 loses its limit, the push shaft 604 moves and drives the oil squeezing plate 607 to move onto the oil filter plate 806. When moving, the oil squeezing plate 607 pushes the impurities and tar on the oil filter plate 806, and the impurities and tar are separated by pushing, thereby playing the role of pushing the impurities and tar.

[0048] like Figures 6 to 8As shown, the top of the support plate 201 is slidably connected with a shift frame 608, and the shift frame 608 is placed at the bottom of the separation box 8. A slag blocking plate 6081 is provided on one side of the separation box 8. The outer wall of the slag blocking plate 6081 can fit with the outer wall of the separation box 8. A limiting plate 10 is fixedly installed on the inner wall of the working box 2. A slag dropping groove is formed between one side of the support plate 201 and the limiting plate 10. Both ends of the slag blocking plate 6081 are slidably connected with the inner wall of the limiting plate 10. Strong compression springs 609 are symmetrically provided between the outer side of the slag blocking plate 6081 and the inner wall of the limiting plate 10. One end of the shift frame 608 is fixedly connected with the bottom of the slag blocking plate 6081.

[0049] When the oil squeezing plate 607 pushes the impurities and tar on the oil filter plate 806, the impurities and tar will be squeezed by the oil filter plate 806 through the limitation of the slag blocking plate 6081, so that the tar will be squeezed out from the impurities and finally enter the bottom of the separation box 8 through the filter holes on the oil filter plate 806. When the thrust rod 603 moves to the moving degree, one end of the thrust rod 603 will push the shift frame 608 to move, so that the shift frame 608 squeezes the strong pressure spring 609 to open, and the impurities can be pushed out from the top of the oil filter plate 806 through the push of the oil squeezing plate 607, thereby separating the impurities and tar.

[0050] like Figures 9 and 10 As shown, a slag sliding ramp 9 is provided at the bottom of the inner wall of the working box 2, one end of the slag sliding ramp 9 is placed just below the slag dropping notch, and the top of the slag sliding ramp 9 is an inclined sliding surface;

[0051] When the impurities are pushed out by the oil squeezing plate 607, the impurities will fall through the slag dropping groove onto the slag sliding ramp 9 for placement. The top inclined sliding surface of the slag sliding ramp 9 is provided to facilitate the flow of the impurities.

[0052] like Figures 7 to 10 As shown, an oil flow pipe 11 is fixedly installed at the bottom of the separation box 8, and a slag box 901 is slidably connected to the other end of the slag sliding ramp 9, and one end of the slag box 901 and one end of the oil flow pipe 11 are both placed outside the working box 2;

[0053] When the tar enters the bottom of the separation box 8, the separated tar can be taken out by connecting a collecting device to the oil flow pipe 11, and the impurities sliding down from the top of the slag ramp 9 can be taken out from the slag box 901 by connecting a slag flow device to the slag box 901, thereby removing the tar impurities.

[0054] like Figures 9 and 10As shown, the outer wall of the slag sliding ramp 9 is slidably connected to the inner wall of the working box 2, a plurality of sieve vibration springs 903 are arranged between the bottom of the slag sliding ramp 9 and the bottom of the inner wall of the working box 2, a convex shaft 902 is rotatably connected to the bottom of the inner wall of the working box 2, and the convex shaft 902 is placed in the middle position of the bottom of the slag sliding ramp 9, one end of the convex shaft 902 and the output end of the motor 7 are fixedly installed with a transmission shaft 702, and the outer walls of the two transmission shafts 702 are transmission-connected with belts 703;

[0055] When the motor 7 rotates, the motor 7 also drives the cam 902 through the transmission shaft 702 and the belt 703. When the cam 902 rotates, the cam 902 pushes the slag sliding ramp 9 to move upward in the working box 2. The slag sliding ramp 9 is continuously reset by the continuous push of the cam 902 and the screening spring 903, so that the slag sliding ramp 9 vibrates in the working box 2, thereby vibrating the impurities on the slag sliding ramp 9 to slide down, preventing the impurities from accumulating on the top of the slag sliding ramp 9, affecting the slag sliding effect, and playing the role of vibrating the slag.

[0056] Working principle: when the furnace door is opened, the smoke detector in the dust guide device 101 captures the smoke, and then the controller 4 controls the pneumatic butterfly valve 3 to open, and then the dust guide device 101 guides the smoke emitted from the furnace door into the dust removal pipe 5. When the smoke flows into the dust removal pipe 5 through the guide of the dust guide device 101, the dust screening mechanism drives the dust filter cotton plate 6 to filter the smoke, and filters out impurities and tar in the smoke from the smoke, preventing the impurities and tar in the smoke from adhering to the inner wall of the dust removal pipe 5 when the smoke flows in the dust removal pipe 5, thereby causing accumulation and blockage, affecting the subsequent smoke flow The filtered flue gas will then flow out along the dust removal pipe 5. By connecting a smoke extinguishing device to one end of the dust removal pipe 5, the flue gas flowing out of the dust removal pipe 5 will enter the smoke extinguishing device for smoke removal. When the smoke removal operation is completed, the dust screening mechanism drives the dust filter cotton plate 6 back to the operation box 2. The separation mechanism in the operation box 2 separates and collects the impurities and tar filtered on the dust filter cotton plate 6, which plays a role in recovering the tar and is convenient for the subsequent use of the tar. When the separation mechanism is finished, the dust screening mechanism drives the dust filter cotton plate 6 back to the dust removal pipe 5, which is convenient for the next filtering operation of the smoke.

[0057] When the smoke has completely passed through the dust filter cotton plate 6, the motor 7 drives the gear 701 to rotate, and the gear 701 drives the plate moving rod 602 to move back through the meshing transmission when rotating, so that the dust filter cotton plate 6 is moved from the dust removal pipe 5 to the working box 2 through the fitting block 601, and the dust filter cotton plate 6 is moved. The fitting block 601 is set to prevent the smoke from flowing into the working box 2 when the smoke flows, so as to limit the flow of the smoke.

[0058] When the dust filter cotton plate 6 moves into the working box 2, the fitting block 601 will squeeze the pressure knife block 801 to move downward. When the pressure knife block 801 moves downward, the scraper 802 drives the moment block 803 to move downward in the inner box 805, so that when the fitting block 601 moves into the working box 2, the scraper 802 will not block the moving path of the fitting block 601. When the fitting block 601 completely passes the scraper 802, the pressure knife block 801 loses its limit, and the scraper 802 is driven by the elastic force of the return spring 804. The bottom of the dust filter cotton plate 6 at one end of the fitting block 601 is reset, thereby scraping the bottom of the dust filter cotton plate 6 at one end, so as to scrape out the impurities and tar attached to the bottom of the dust filter cotton plate 6. At the same time, scraping out the impurities and tar attached to the bottom of the dust filter cotton plate 6 is also conducive to the subsequent dust filter cotton plate 6 to filter the smoke, and prevent the filter holes of the dust filter cotton plate 6 from being blocked. When the impurities and tar are scraped off, the impurities and tar scraped off will enter the separation box 8 from the slag outlet through the limiting position of the slag limiting block 8021, so as to scrape off the impurities and tar.

[0059] When the impurities and tar fall from the slag outlet, they will fall on the oil filter plate 806, which plays a role of placement, making it easier for the separation mechanism to separate the two.

[0060] As impurities and tar continuously fall on the oil filter plate 806, the weight of the impurities and tar will squeeze the oil filter plate 806 downward, and the oil filter plate 806 will squeeze the return plate spring 807 downward when it moves downward. When the oil filter plate 806 moves to a certain extent, the separation mechanism separates the impurities and tar accumulated inside it, playing the role of slag gathering.

[0061] When the oil filter plate 806 moves down to a certain extent, the oil squeezing plate 607 loses its limit position, and the gear 701 drives the thrust rod 603 to move while the motor 7 drives the rotation. When the thrust rod 603 moves, the thrust shaft 604 drives the thrust plate 604 to move. When one side of the oil squeezing plate 607 loses its limit position, the thrust shaft 604 moves and drives the oil squeezing plate 607 to move onto the oil filter plate 806. When the oil squeezing plate 607 moves, it pushes the impurities and tar on the oil filter plate 806, and the impurities and tar are separated by pushing, thereby playing the role of pushing the impurities and tar.

[0062] Through the limitation of the slag blocking plate 6081, the impurities and tar will be squeezed by the oil filter plate 806, so that the tar will be squeezed out of the impurities, and finally enter the bottom of the separation box 8 through the filter holes on the oil filter plate 806. When the thrust rod 603 moves to the moving degree, one end of the thrust rod 603 will push the shift frame 608 to move, so that the shift frame 608 squeezes the strong pressure spring 609 to open, and the impurities can be pushed out from the top of the oil filter plate 806 by the push of the oil squeezing plate 607, so as to separate the impurities and tar.

[0063] When the impurities are pushed out by the oil squeezing plate 607, the impurities will fall through the slag dropping notch onto the slag sliding ramp 9 for impurity placement. The top inclined surface of the slag sliding ramp 9 is provided to facilitate the flow of impurities.

[0064] When the tar enters the bottom of the separation box 8, a collecting device is connected to the oil flow pipe 11 to remove the separated tar. A slag flow device is connected to the slag box 901 to remove the impurities sliding down from the top of the slag ramp 9 from the slag box 901, thereby removing the tar impurities.

[0065] When the motor 7 rotates, the motor 7 also drives the cam 902 through the transmission shaft 702 and the belt 703. When the cam 902 rotates, the cam 902 pushes the slag sliding ramp 9 to move upward in the working box 2. The slag sliding ramp 9 is continuously reset by the continuous push of the cam 902 and the screening spring 903, so that the slag sliding ramp 9 vibrates in the working box 2, thereby vibrating the impurities on the slag sliding ramp 9 to slide down, preventing the impurities from accumulating on the top of the slag sliding ramp 9, affecting the slag sliding effect, and playing the role of vibrating the slag.

For those skilled in the art, other different forms of changes or modifications can be made based on the above description.
