Description

Technical Field

[0001] The invention relates to the technical field of material transportation, in particular to dry scraper slag discharging equipment. Background Art

[0002] Currently, a large amount of ash is generated during the operation of thermal power plants and chemical boilers. There are two main ways to treat the ash. One is wet slag discharge. The main disadvantage of the wet slag discharge system is that it relies on a large amount of cooling water, which can lead to the following problems: water resource waste and secondary pollution: the infiltration of heavy metal ions in the high-humidity ash.

[0003] The second is the dry scraper slag discharge equipment, whose core function is to transport the hot slag produced by boiler combustion to the slag bin through the scraper chain under water-free or trace spraying conditions, thereby achieving energy-saving and environmentally friendly continuous slag discharge.

[0004] However, the current dry scraper slag discharge equipment has some defects. For example, when transporting ash, the bottom of the scraper needs to be in contact with the transmission bottom plate to ensure that the ash can be transported in a centralized manner. However, after long-term use, the contact area between the bottom of the scraper and the transmission bottom plate will be severely worn, resulting in a gap between the two, which in turn causes the ash to leak during transportation. When the bottom of the scraper is more worn, it needs to be replaced. In order to ensure the stability of the transmission, the scraper is generally fixed between the chains, which is currently more troublesome to replace.

[0005] Therefore, it is necessary to provide a dry scraper slag discharging device to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute the prior art. Summary of the Invention

[0007] The technical solution adopted by the present invention to solve its technical problems is: a dry scraper slag discharging equipment, including a discharge rack, a conveying plate fixedly installed inside the discharge rack, the conveying plate is divided into a horizontal section and an inclined section, the horizontal section is used to receive slag, and the inclined section is used to drain and lift the slag, and a scraper chain is rotatably set on the inner wall of the discharge rack, the conveying direction of the scraper chain is the same as the conveying direction of the conveying plate, the scraper chains are arranged in two groups, and are symmetrically designed relative to the conveying plate, slag scrapers arranged at equal distances are arranged between adjacent scraper chains, a sealing frame is provided above the discharge rack, and the lower end face of the slag scraper is in contact with the upper end face of the conveying plate.

[0008] Furthermore, a cylindrical pin is fixedly installed on the surface of the scraper chain link, and a hinge is provided for rotation inside the cylindrical pin, and the slag scraper is fixedly installed on the side wall of the hinge; when working, the slag scraper is installed in the cylindrical pin through the hinge and connected to the chain link of the scraper chain, so that the slag scraper can form a flexible connection structure, which makes it convenient for the slag scraper to have a certain degree of freedom of deflection when following the movement of the scraper chain, which is beneficial to the transportation of ash and the dispersion of accumulated ash.

[0009] Furthermore, a rectangular groove is provided at the bottom of the slag scraper, and a wear-resistant plate is rotatably provided on the groove wall of the rectangular groove, and the wear-resistant plate is provided with multiple wear-resistant surfaces. The wear-resistant plate can rotate on the groove wall of the rectangular groove and replace different wear-resistant surfaces; during operation, when the slag scraper conveys ash, the wear-resistant plate at the bottom of the slag scraper will contact the upper end surface of the conveying plate, and the wear-resistant plate will gradually convey the ash from the horizontal section of the conveying plate to the side of the inclined section. When the contact surface between the wear-resistant plate and the upper end surface of the conveying plate is worn to a certain extent, the wear-resistant plate can be controlled to rotate so that the wear-resistant plate rotates to the remaining angles, that is, the remaining surfaces contact the upper end surface of the conveying plate. This can ensure that the wear-resistant plate is closely fitted with the upper end surface of the conveying plate, which is beneficial to the conveying of ash and avoids the problem that there is a gap between the wear-resistant plate and the upper end surface of the conveying plate, which makes it difficult to convey some ash.

[0010] Furthermore, a round rod is fixedly installed on the groove wall of the rectangular groove, a through groove 1 is opened on the inner wall of the round rod, a circular groove is opened inside the through groove 1, and an installation unit is provided on the side wall of the wear-resistant plate, and the installation unit is used to install the wear-resistant plate into the through groove 1 and the circular groove.

[0011] Furthermore, the installation unit includes a through rod, which is installed on the side wall of the wear-resistant plate. The groove wall of the through groove is provided with a transverse groove. An elastic arc seat is installed on the surface of the through rod, and the groove wall of the circular groove is provided with an arc-shaped groove.

[0012] Furthermore, the end of the through-rod close to the through-slot 1 is of telescopic design, the shape of the through-rod end is adapted to the shape of the through-slot 1, and the end of the through-rod away from the through-slot 1 penetrates into the interior of the wear-resistant plate; During operation, since the end of the through-rod close to the through-groove 1 is telescopically designed, the through-rod can conveniently drive the elastic arc seat to move along the through-groove 1 and the transverse groove, so that the end of the through-rod is disengaged from the transverse groove; and the end of the wear-resistant plate away from the through-groove 1 penetrates into the interior of the wear-resistant plate, which makes it convenient for the through-rod to drive the elastic arc seat to rotate inside the circular groove, so that the elastic arc seat is stuck in the arc-shaped groove inside the circular groove.

[0013] Furthermore, a spring is provided inside the elastic arc seat, and the shape of the elastic arc seat is adapted to the shape of the arc groove. A plurality of arc grooves are designed, and are designed in a circular array inside the circular groove. During operation, when the wear-resistant plate is installed, that is, when the elastic arc seat moves along the transverse groove and rotates along the wall of the circular groove, the transverse groove and the circular groove will squeeze the spring inside the elastic arc seat, so that the elastic arc seat is in an extruded state. When the elastic arc seat rotates to the inside of one of the circular grooves, the elastic arc seat will be tightly stuck in the arc groove under the pressure of the spring inside the elastic arc seat, thereby ensuring the stability of the wear-resistant plate when conveying ash.

[0014] Furthermore, the scraper chain is controlled to rotate by multiple driving gears, and a rotating horizontal shaft is installed on the side wall of each driving gear. The rotating horizontal shafts are connected by belts, and a cleaning unit is provided on the upper side of the inner wall of the sealing frame. The cleaning unit is used to clean the slag scraper moved to the discharge port; during operation, when the scraper chain drives the slag scraper to rotate along the direction of the conveying plate, the scraper chain will be conveyed by the rotation of multiple driving gears, and since multiple driving gears are designed, the stability of the scraper chain during the conveying process can be ensured, thereby facilitating the movement of the slag scraper along the conveying plate.

[0015] Furthermore, the cleaning unit includes a conical scraper, which is designed to slide on the inner wall of the sealing frame, and the conical scraper is arranged above the discharge port. The conical scraper is controlled to slide by an electric telescopic rod, and the electric telescopic rod is installed inside the sealing frame; during operation, when one group of slag scrapers moves to the direction close to the discharge port and corresponds to the conical scraper, the telescopic end of the electric telescopic rod is controlled to move downward, so that it drives the conical scraper to move downward, and then the conical scraper contacts the surface of the slag scraper and moves from top to bottom along the slag scraper, so that some ash with higher viscosity on the surface of the slag scraper is scraped to the bottom of the discharge port, which facilitates the subsequent recycling of the slag scraper.

[0016] Furthermore, a connecting gear is installed at the end of each rotating horizontal axis, and a plurality of incomplete gears are rotatably provided on the inner wall of the discharge rack. The incomplete gears are meshed with the connecting gears, and the ends of the incomplete gears are connected to the output end of the motor.

[0017] The beneficial effects of the present invention are as follows: a dry scraper slag discharging equipment provided by the present invention moves along the transverse groove through the elastic arc seat and rotates along the circular groove wall. The transverse groove and the circular groove will squeeze the spring inside the elastic arc seat, so that the elastic arc seat is in an extruded state; when the elastic arc seat rotates to the inside of one of the circular grooves, under the pressure of the spring inside the elastic arc seat, the elastic arc seat will be tightly stuck in the arc groove, thereby ensuring the stability of the wear-resistant plate when conveying ash.

[0018] When the contact surface between the wear-resistant plate and the upper end surface of the conveying plate is worn to a certain extent, the wear-resistant plate can be controlled to rotate to other angles, that is, the other surface contacts the upper end surface of the conveying plate. This ensures that the wear-resistant plate and the upper end surface of the conveying plate are closely fitted, which is beneficial to the conveying of ash and avoids the gap between the wear-resistant plate and the upper end surface of the conveying plate, which makes it difficult to convey some ash. In addition to the above-described objects, features and advantages, the present invention has other objects, features and advantages.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0023] like Figures 1 to 11 As shown, the present invention provides a dry scraper slag discharging equipment, including a discharge frame 1, a conveying plate 2 is fixedly installed inside the discharge frame 1, and the conveying plate 2 is divided into a horizontal section and an inclined section, the horizontal section is used to receive slag, and the inclined section is used to drain and lift the slag, and a scraper chain 3 is rotatably provided on the inner wall of the discharge frame 1, and the conveying direction of the scraper chain 3 is the same as the conveying direction of the conveying plate 2, and the scraper chains 3 are provided in two groups, and are symmetrically designed relative to the conveying plate 2, and slag scrapers 4 arranged at equal distances are provided between adjacent scraper chains 3, and a sealing frame 101 is provided above the discharge frame 1, and the lower end surface of the slag scraper 4 contacts the upper end surface of the conveying plate 2, and a detachable wear-resistant plate 7 is provided inside the slag scraper 4, and the wear-resistant plate 7 contacts the upper end surface of the conveying plate 2; It should be noted that the device in the embodiment of the present invention can be directly arranged vertically below the slag outlet of the boiler furnace and corresponds to the horizontal plane of the conveying plate 2; During operation, the ash generated in the boiler production process will fall from its slag outlet to the horizontal surface of the conveying plate 2, and then the scraper chain 3 is controlled to rotate synchronously, so that the scraper chain 3 drives the slag scraper 4 connected thereto to move. Since the lower end surface of the wear-resistant plate 7 is in contact with the upper end surface of the conveying plate 2, the lower end surface of the slag scraper 4 will be tightly fitted with the upper end surface of the conveying plate 2, and with the transmission of the scraper chain 3, the ash can be gradually moved along the horizontal surface of the conveying plate 2 to the side of the inclined surface until it is transported to the discharge port at the inclined surface of the conveying plate 2. When the slag scraper 4 transports the slag from the inclined section, it can lift the ash and drain off the residual moisture, thereby achieving the dry slag discharging requirements, and a sealing frame 101 is designed to design the entire slag discharging environment as a sealed environment to reduce dust emission; At the same time, the wear-resistant plate 7 is designed to be a detachable structure, so that when the bottom of the wear-resistant plate 7 and the contact part of the wear-resistant plate 7 are severely worn, it can be disassembled to avoid the existence of a gap between the two, which will cause the ash to leak during transportation. The disassembly and clamping speed is fast and the operation is convenient.

[0024] A cylindrical pin 5 is fixedly installed on the surface of the chain link of the scraper chain 3, and a hinge 501 is rotatably provided inside the cylindrical pin 5. The slag scraper 4 is fixedly installed on the side wall of the hinge 501. When working, the slag scraper 4 is installed in the cylindrical pin 5 through the hinge 501 and connected to the chain link of the scraper chain 3. In this way, the slag scraper 4 can form a flexible connection structure, which makes it convenient for the slag scraper 4 to have a certain degree of freedom of deflection when following the movement of the scraper chain 3, which is beneficial to the transportation of ash and the dispersion of accumulated ash.

[0025] A rectangular groove 6 is provided at the bottom of the slag scraper 4, and the wear-resistant plate 7 is rotatably designed on the groove wall of the rectangular groove 6. The wear-resistant plate 7 is provided with multiple wear-resistant surfaces. The wear-resistant plate 7 can rotate on the groove wall of the rectangular groove 6 and replace different wear-resistant surfaces. During operation, when the slag scraper 4 transports the ash, the wear-resistant plate 7 at the bottom of the slag scraper 4 will contact the upper end surface of the conveying plate 2, and the wear-resistant plate 7 will gradually transport the ash from the horizontal section of the conveying plate 2 to the side of the inclined section. When the contact surface between the wear-resistant plate 7 and the upper end surface of the conveying plate 2 is worn to a certain extent, the wear-resistant plate 7 can be controlled to rotate so that the wear-resistant plate 7 is rotated to the remaining angles, that is, the remaining surfaces are in contact with the upper end surface of the conveying plate 2. This ensures that the wear-resistant plate 7 fits tightly with the upper end surface of the conveying plate 2, which is beneficial to the transportation of the ash and avoids the problem that there is a gap between the wear-resistant plate 7 and the upper end surface of the conveying plate 2, which makes it difficult to transport some ash.

[0026] A round rod 8 is fixedly mounted on the wall of the rectangular groove 6. A through groove 801 is formed on the inner wall of the round rod 8. A circular groove 9 is formed inside the through groove 801. A mounting unit is provided on the side wall of the wear-resistant plate 7. The mounting unit is used to mount the wear-resistant plate 7 into the through groove 801 and the circular groove 9. During operation, the wear-resistant plate 7 is designed to be installed in the through groove 801 and the circular groove 9 through the installation unit. When one of the surfaces of the wear-resistant plate 7 is severely worn, the installation unit can be controlled to rotate inside the circular groove 9, so that the installation unit drives the wear-resistant plate 7 to rotate to a certain angle, and then the remaining surface of the wear-resistant plate 7 can contact the upper end surface of the conveying plate 2; It should be noted that the gap between the wear-resistant plate 7 and the rectangular groove 6 may be sufficient to allow the wear-resistant plate 7 to rotate.

[0027] The mounting unit includes a through rod 10, which is mounted on the side wall of the wear-resistant plate 7. The wall of the through slot 1 801 is provided with a transverse groove 11. An elastic arc seat 12 is mounted on the surface of the through rod 10. The wall of the circular slot 9 is provided with an arc groove 13. It should be noted that the slag discharge equipment in the embodiment of the present invention needs to be inspected and the wear-resistant plate 7 replaced when it has been used for a certain period, and the certain period here can be one month; when the wear-resistant plate 7 is in normal use, the elastic arc seat 12 is located inside the arc groove 13; when the wear-resistant plate 7 needs to be replaced, the staff can manually rotate the through rod 10 so that the through rod 10 drives the elastic arc seat 12 to rotate on the inner wall of the circular groove 9, that is, the through rod 10 drives the elastic arc seat 12 to disengage from the arc groove 13, and rotates the through rod 10 and the elastic arc seat 12 to be in the same horizontal plane as the transverse groove 11, and then pulls the through rod 10 to the side away from the through groove 1 801, that is, the through rod 10 is disengaged from the through groove 1 801, so that the wear-resistant plate 7 can be taken out; Then take a new wear-resistant plate 7, so that the through rod 10 on the surface of the new wear-resistant plate 7 moves along the through groove 801 and the transverse groove 11. After that, when the elastic arc seat 12 moves to the side of the circular groove 9, rotate the through rod 10 so that the elastic arc seat 12 is stuck in the arc groove 13 inside the circular groove 9. In this way, the wear-resistant plate 7 can be replaced, which is conducive to the continued transportation of ash.

[0028] The end of the through rod 10 close to the through slot 1 801 is of telescopic design. The shape of the end of the through rod 10 matches the shape of the through slot 1 801. The end of the through rod 10 away from the through slot 1 801 penetrates into the interior of the wear-resistant plate 7. During operation, since the end of the through rod 10 close to the through groove 801 is telescopically designed, the through rod 10 can conveniently drive the elastic arc seat 12 to move along the through groove 801 and the transverse groove 11, so that the end of the through rod 10 is disengaged from the transverse groove 11; and the end of the wear-resistant plate 7 away from the through groove 801 penetrates into the inside of the wear-resistant plate 7, which makes it convenient for the through rod 10 to drive the elastic arc seat 12 to rotate inside the circular groove 9, so that the elastic arc seat 12 is stuck in the arc groove 13 inside the circular groove 9.

[0029] A spring is provided inside the elastic arc seat 12. The shape of the elastic arc seat 12 matches the shape of the arc groove 13. There are multiple arc grooves 13 designed and arranged in a circular array inside the circular groove 9. During operation, when the wear-resistant plate 7 is installed, that is, when the elastic arc seat 12 moves along the transverse groove 11 and rotates along the groove wall of the circular groove 9, the transverse groove 11 and the circular groove 9 will squeeze the spring inside the elastic arc seat 12, so that the elastic arc seat 12 is in an extruded state; when the elastic arc seat 12 rotates to the inside of one of the circular grooves 9, under the pressure of the spring inside the elastic arc seat 12, the elastic arc seat 12 will be tightly stuck in the arc groove 13, so as to ensure the stability of the wear-resistant plate 7 when conveying ash; Moreover, when it is necessary to rotate the wear-resistant plate 7 so that different surfaces of the wear-resistant plate 7 are in contact with the conveying plate 2, it is only necessary to rotate the through-rod 10 again, so that the through-rod 10 drives the elastic arc seat 12 to separate from one of the arc-shaped grooves 13, and drives the wear-resistant plate 7 to rotate, and then the elastic arc seat 12 is clamped in the other arc-shaped grooves 13; It should be noted that the angle between adjacent arc-shaped grooves 13 can enable one side of the wear-resistant plate 7 to just rotate to the other side, that is, when the elastic arc seat 12 is stuck inside the arc-shaped groove 13, the surface of the wear-resistant plate 7 can just contact the upper end surface of the conveying plate 2.

[0030] The scraper chain 3 is controlled to rotate by a plurality of drive gears 14. A rotating horizontal shaft 15 is installed on the side wall of each drive gear 14. The rotating horizontal shafts 15 are connected by belts. A cleaning unit is provided on the upper side of the inner wall of the sealing frame 101. The cleaning unit is used to clean the slag scraper 4 moved to the discharge port. During operation, when the scraper chain 3 drives the slag scraper 4 to rotate along the direction of the conveyor plate 2, the scraper chain 3 will be transported through the rotation of multiple drive gears 14, and because multiple drive gears 14 are designed, the stability of the scraper chain 3 during the conveying process can be ensured, thereby facilitating the movement of the slag scraper 4 along the conveyor plate 2.

[0031] The cleaning unit includes a conical scraper 16, which is designed to slide on the inner wall of the sealing frame 101. The conical scraper 16 is arranged above the discharge port. The conical scraper 16 is controlled to slide by an electric telescopic rod 17, which is installed inside the sealing frame 101. During operation, when one group of slag scrapers 4 moves to the direction close to the discharge port and corresponds to the conical scraper 16, the telescopic end of the electric telescopic rod 17 is controlled to move downward, so that it drives the conical scraper 16 to move downward. Then the conical scraper 16 contacts the surface of the slag scraper 4 and moves from top to bottom along the slag scraper 4, so that some ash with higher viscosity on the surface of the slag scraper 4 is scraped to the bottom of the discharge port, which facilitates the subsequent recycling of the slag scraper 4.

[0032] A connecting gear 18 is installed at the end of each rotating horizontal shaft 15, and a plurality of incomplete gears 19 are rotatably provided on the inner wall of the discharge rack 1. The incomplete gears 19 are meshed and connected with the connecting gears 18, and the ends of the incomplete gears 19 are connected to the output end of the motor; During operation, by controlling the rotation of the incomplete gear 19, the incomplete gear 19 will drive the connecting gear 18 meshing with it to rotate, the connecting gear 18 will drive the rotating horizontal shaft 15 to rotate, and the rotating horizontal shaft 15 will drive the driving gear 14 to rotate, thus realizing the transmission of the scraper chain 3; When the incomplete gear 19 and the connecting gear 18 rotate from the ratchet meshing position to the non-meshing position, the slag scraper 4 of the group just moves to the discharge port and is aligned with the conical scraper 16. At this time, the sticky material on the surface of the slag scraper 4 can be scraped off through the above steps; then, as the incomplete gear 19 rotates, it will mesh with the connecting gear 18 again, that is, the scraper chain 3 will be transmitted again, so that the scraper chain 3 can be transmitted intermittently, that is, it is convenient to clean the surface of the slag scraper 4; It should be noted that the distance that the slag scraper 4 moves when the incomplete gear 19 and the connecting gear 18 rotate from the ratchet engagement position to the non-engagement position is exactly the distance between adjacent slag scrapers 4, so that the slag scrapers 4 at different positions can be intermittently moved above the discharge port.

[0033] Working principle: the ash generated during the boiler production process will fall from its slag outlet to the horizontal surface of the conveying plate 2, and then the two sets of scraper chains 3 are controlled to rotate synchronously, so that the scraper chain 3 drives the slag scraper 4 connected thereto to move. Since the lower end surface of the slag scraper 4 is in contact with the upper end surface of the conveying plate 2, the lower end surface of the slag scraper 4 will be tightly fitted with the upper end surface of the conveying plate 2, and with the transmission of the scraper chain 3, the ash can be gradually moved along the horizontal surface of the conveying plate 2 to the side of the inclined surface until it is transported to the discharge port at the inclined surface of the conveying plate 2. When the slag scraper 4 transports the slag from the inclined section, it can lift the ash and drain away residual moisture, thereby achieving the dry slag discharge requirements, and a sealing frame 101 is designed to design the entire slag discharge environment into a sealed environment to reduce dust emission; When the slag scraper 4 conveys the ash, the wear-resistant plate 7 at the bottom of the slag scraper 4 will contact the upper end surface of the conveying plate 2, and the wear-resistant plate 7 will gradually convey the ash from the horizontal section of the conveying plate 2 to the side of the inclined section. When the contact surface between the wear-resistant plate 7 and the upper end surface of the conveying plate 2 is worn to a certain extent, the wear-resistant plate 7 can be controlled to rotate so that the wear-resistant plate 7 is rotated to the remaining angle, that is, the remaining surface is in contact with the upper end surface of the conveying plate 2. This can ensure that the wear-resistant plate 7 is closely fitted with the upper end surface of the conveying plate 2, which is beneficial to the transportation of the ash and avoids the gap between the wear-resistant plate 7 and the upper end surface of the conveying plate 2, which makes it difficult for some ash to be transported. To solve the problem of transportation; when the wear-resistant plate 7 is in normal use, the elastic arc seat 12 is located inside the arc groove 13; when the wear-resistant plate 7 needs to be replaced, the staff can manually rotate the penetration rod 10 so that the penetration rod 10 drives the elastic arc seat 12 to rotate on the inner wall of the circular groove 9, that is, the penetration rod 10 drives the elastic arc seat 12 to disengage from the arc groove 13, and rotate the penetration rod 10 and the elastic arc seat 12 to be in the same horizontal plane as the transverse groove 11, and then pull the penetration rod 10 to the side away from the penetration groove 1801, that is, the penetration rod 10 is disengaged from the penetration groove 1801, so that the wear-resistant plate 7 can be taken out; Then, take out the new wear-resistant plate 7, make the through rod 10 on the surface of the new wear-resistant plate 7 move along the through groove 1 801 and the transverse groove 11, and then when the elastic arc seat 12 moves to the side of the circular groove 9, rotate the through rod 10 again so that the elastic arc seat 12 is stuck in the arc groove 13 inside the circular groove 9, and the wear-resistant plate 7 can be replaced, which is conducive to the continued transportation of ash; When the cam 12 is in the state of being pressed down, the spring 12 of the cam 12 is pressed against the spring 13 and the spring 13 is engaged with the cam 12, and the cam 12 is engaged with the spring 13. And when it is necessary to rotate the wear-resistant plate 7 so that different surfaces of the wear-resistant plate 7 contact the conveying plate 2, it is only necessary to rotate the through-rod 10 again so that the through-rod 10 drives the elastic arc seat 12 to separate from one of the arc grooves 13 and drives the wear-resistant plate 7 to rotate, and then the elastic arc seat 12 is stuck in the remaining arc grooves 13; when one group of slag scrapers 4 moves toward the direction close to the discharge port and corresponds to the conical scraper 16, at this time, the telescopic end of the electric telescopic rod 17 is controlled to move downward, so that it drives the conical scraper 16 to move downward, and then the conical scraper 16 contacts the surface of the slag scraper 4 and moves from top to bottom along the slag scraper 4, so that some ash with greater viscosity on the surface of the slag scraper 4 is scraped to the bottom of the discharge port, which is convenient for the subsequent recycling of the slag scraper 4; By controlling the rotation of the incomplete gear 19, the incomplete gear 19 will drive the connecting gear 18 meshing with it to rotate, the connecting gear 18 will drive the rotating horizontal shaft 15 to rotate, and the rotating horizontal shaft 15 will drive the driving gear 14 to rotate, thus realizing the transmission of the scraper chain 3; When the incomplete gear 19 and the connecting gear 18 rotate from the ratchet engagement position to the non-engagement position, at this time, one set of slag scrapers 4 also just moves to the discharge port and is aligned with the conical scraper 16. At this time, the sticky material on the surface of the slag scraper 4 can be scraped off through the above steps; then as the incomplete gear 19 rotates, it will mesh with the connecting gear 18 again, that is, the scraper chain 3 will be transmitted again, so that the scraper chain 3 can be transmitted intermittently, which is convenient for cleaning the surface of the slag scraper 4.

Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
