Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, and in particular to a steam collection, recovery and treatment system for an industrial cooling tower. Background Art

[0002] In the cooling process of steel slag, a cooling tower is needed to spray water to cool it. It mainly sends the high-temperature steel slag into the carrying device in the cooling tower, and then sprays cooling water to thoroughly dredge the accumulated steel slag to cool and break the steel slag. In this process, a large amount of water vapor and harmful gases will be generated, and the mixed airflow will form a hot airflow that is sprayed from the tower mouth of the cooling tower to the outside.

[0003] The invention patent with authorization announcement number CN 115522002 B discloses the architecture of a cooling tower steam collection, recovery and processing device, including a cooling tower, a water reservoir at the bottom of the cooling tower, and a water pump in the water reservoir. The output end of the water pump is provided with a water-cooling pipe device, and the cooling tower is provided with a drainage purification device. A filter layer is fixedly connected to the middle of the inner cavity of the cooling tower, and a symmetrical rotating tube is movably connected to the top of the inner cavity of the cooling tower, and a transmission tooth is provided on the outer side of one end of one of the rotating tubes, and a motor II is fixedly connected to the outer wall of the cooling tower.

[0004] This invention sends the hot air flow into the transmission pipe through an axial flow fan, and sends the hot air flow into the condensation assembly through an induced draft fan, so that the water vapor in the hot air flow is condensed into liquid. After separation from the harmful gas, it is returned to the water storage tank through a reflux pipe for recycling. At the same time, the harmful gas will be purified through the gas purification assembly, and the clean gas will be discharged into the atmosphere, avoiding the pollution problem caused by the emission of harmful gases.

[0005] However, after actual application by technicians in this field, it was found that the above-mentioned device still has some shortcomings. The most obvious one is that due to the limitations of the shape and structure, a lot of time is needed to load and unload the slag before and after the cooling starts, resulting in a long interval between two adjacent cooling operations, which not only affects the cooling efficiency of the slag, but also increases the cooling cost of the slag. In addition, a large amount of water vapor is generated when the slag comes into contact with cooling water during the cooling process. Due to the restrictions on the inlet and outlet of the slag, the device cannot be closed. Therefore, in the actual cooling process, when the water vapor is only guided by an axial flow fan, it is easy for the steam to escape into the working environment through the opening of the device, and the cooled slag needs to be manually removed. The actual use effect is not ideal.

[0006] Therefore, it is necessary to invent an industrial cooling tower steam collection and recovery processing system to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide an industrial cooling tower steam collection and recovery treatment system, which is provided with a first driving mechanism, a sealed water supply and exhaust mechanism, a second driving mechanism, a synchronous transposition mechanism, a dumping structure and a slag containing mechanism, so that after the first driving mechanism drives the sealed water supply and exhaust mechanism and the second driving mechanism to move downward synchronously, the sealed water supply and exhaust mechanism seals, supplies water and exhausts steam to the adjacent slag containing mechanism, and the second driving mechanism drives the synchronous transposition mechanism ineffectively. When the first driving mechanism subsequently drives the sealed water supply and exhaust mechanism and the second driving mechanism to rise synchronously, the sealed water supply and exhaust mechanism releases the seal on the adjacent slag containing mechanism, and the second driving mechanism drives the synchronous transposition mechanism to drive the two groups of slag containing mechanisms. The slag containing mechanism is replaced to solve the problem raised in the above background technology that due to the limitations of the shape and structure, a lot of time is needed to carry out loading and unloading operations on the steel slag before and after the cooling starts, resulting in a long interval between two adjacent cooling operations, which not only affects the cooling treatment efficiency of the steel slag, but also increases the cooling cost of the steel slag. In addition, a large amount of water vapor will be generated when the steel slag comes into contact with cooling water during the cooling process. Due to the restrictions on the inlet and outlet of the steel slag, the device cannot be closed. Therefore, in the actual cooling process, when the water vapor is only guided by an axial flow fan, it is easy for the steam to escape into the working environment through the opening of the device, and the cooled slag needs to be manually removed, and the actual use effect is not ideal.

[0027] The present invention also discloses a method for collecting and recovering steam from an industrial cooling tower, which specifically comprises the following steps:

[0028] S1. Put the steel slag to be cooled into the right containing tube through the top opening of the right containing tube, start the driving motor, and after the driving motor is started, the reciprocating screw is driven to rotate continuously. When the reciprocating screw rotates, the square driving column is driven to rotate through the square driving groove, and when the square driving column rotates, the paddle is driven to rotate through the rotating disk;

[0029] S2, when the reciprocating screw rotates, it drives the outer sleeve down, when the outer sleeve descends, it drives the inner sleeve down through the first spring, drives the connecting column down through the outer sleeve plate, when the inner sleeve descends, it drives the rotating disk to descend synchronously, when the connecting column descends, it drives the first magnet to descend through the second spring and the one-way screw, in this process, the one-way screw drives the threaded sleeve to rotate, and due to the limitation of the overrunning clutch, the rotating seat does not rotate;

[0030] S3, when the outer sleeve descends to a first threshold, the sealing ring fits against the top of the adjacent accommodating tube and cooperates with the rotating disk to close the top opening of the accommodating tube. At this time, the output end of the water inlet pipe is inserted into the adjacent L-shaped water inlet channel, and the input end of the exhaust pipe is inserted into the adjacent L-shaped exhaust channel. Then, the water pump on the water inlet pipe is started, and the water pump inputs cooling water into the L-shaped water inlet channel through the water inlet pipe. Then, the cooling water enters the bottom of the inner cavity of the accommodating tube and forms a water flow to rush toward the steel slag on the top of the mesh plate under the restriction of the holes on the mesh plate;

[0031] S4, the water flow contacts the steel slag to cool it, and the generated water vapor enters the exhaust pipe through the L-shaped exhaust channel, and then enters the condensation assembly through the exhaust pipe to be condensed, and the condensed water is returned to the water tank for reuse, and the gas is purified and discharged by the gas purification assembly. In this process, the steel slag to be cooled is added to the left holding cylinder;

[0032] S5. During the process of cooling the slag by water flow, the water flow also pushes the slag, thereby causing the slag to move upward. After the slag moves upward, it comes into contact with the continuously rotating paddle, and the paddle paddle paddles the slag, thereby causing the slag to be cooled more quickly.

[0033] S6. Since the sealing ring is attached to the top of the adjacent accommodating tube, the inner sleeve cannot continue to descend due to the obstruction of the accommodating tube. As the outer sleeve continues to descend, the first spring is compressed, and the reciprocating screw continues to drive the first magnet to descend through the outer sleeve plate, the connecting column, the one-way screw and the second spring.

[0034] S7, when the outer sleeve descends to a second threshold, the first magnet contacts the second magnet, and the outer sleeve moves to the bottom of the reciprocating thread outside the reciprocating screw. As the reciprocating screw continues to rotate, the outer sleeve moves upward and resets. During this process, since the first magnet is attracted by the second magnet, the one-way screw does not rise with the outer sleeve, and the second spring is continuously stretched;

[0035] S8, when the outer sleeve rises to a third threshold, the compressed first spring is restored, and the slag inside the accommodating tube is cooled down. Subsequently, as the outer sleeve continues to rise, the sealing ring drives the output end of the water inlet pipe to rise inside the L-shaped water inlet channel, and drives the input end of the exhaust pipe to rise inside the L-shaped exhaust channel;

[0036] S9. When the rising distance of the outer sleeve reaches the fourth threshold, the output end of the water inlet pipe moves out from the inner side of the L-shaped water inlet channel, and the input end of the exhaust pipe moves out from the inner side of the L-shaped exhaust channel. At the same time, the second spring is stretched to the extreme value. Subsequently, as the outer sleeve continues to rise, the outer sleeve drives the one-way screw to rise through the outer sleeve plate, the connecting column and the second spring, and the one-way screw drives the first magnet to separate from the second magnet. At this time, the stretched second spring drives the one-way screw to move up and reset, and drives the threaded sleeve to rotate during the one-way screw to move up. At this time, the threaded sleeve drives the rotating seat to rotate, so that the two slag containing mechanisms are exchanged, that is, the containing barrel with the cooled slag is transferred to the feeding and discharging station, and the containing barrel with the slag to be cooled is transferred to the cooling station;

[0037] S10, when the rising distance of the outer sleeve reaches the fifth threshold, the outer sleeve moves to the reciprocating top end outside the reciprocating screw, and then as the reciprocating screw continues to rotate, the outer sleeve moves down again. During this process, the dumping structure is used to automatically dump the slag in the containing tube.

[0038] Technical effects and advantages of the present invention:

[0039] 1. Improve cooling efficiency: Through the coordinated work of the synchronous transposition mechanism and the sealed water supply and exhaust mechanism, continuous operation during the cooling process of the slag is achieved, the interval between two adjacent cooling operations is reduced, and the cooling efficiency of the slag is improved.

[0040] 2. Automatic dumping of slag: The dumping structure can automatically dump the cooled slag during the rotation and transposition process of the synchronous transposition mechanism, without the need for manual removal, saving labor costs and improving work efficiency.

[0041] 3. Prevent steam from escaping: The sealed water supply and exhaust mechanism seals the slag containment mechanism during the cooling process, effectively preventing steam from escaping into the working environment through the opening of the device, reducing pollution to the environment.

[0042] 4. Reduce cooling costs: Continuous operation reduces equipment idle time, thereby reducing the cooling cost of slag.

[0043] 5. Promote resource recycling: condense and recycle steam, return condensed water to the water tank for reuse, and discharge gas after purification, thus realizing the recycling of resources and meeting environmental protection requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] By setting the above-mentioned first driving mechanism 3 and the sealed water supply and exhaust mechanism 4, the driving motor 32 can drive the reciprocating screw 31 to rotate continuously after starting. When the reciprocating screw 31 rotates, it drives the square driving column 41 to rotate through the square driving groove 33. When the square driving column 41 rotates, it drives the dial plate 43 to rotate through the rotating disk 42. When the reciprocating screw 31 rotates, it drives the outer sleeve 34 to descend. When the outer sleeve 34 descends, it drives the inner sleeve 36 to descend through the first spring 35. When the inner sleeve 36 descends, it drives the rotating disk 42 to descend synchronously.

[0060] It should also be noted that the condensation assembly and the gas purification assembly are both solutions that have been disclosed in the prior art and are not essential technical features of the present application. Therefore, the present application does not elaborate on their specific structures.

[0061] like Figure 2 As shown, the second driving mechanism 5 includes an outer sleeve plate 51, a connecting column 52, a one-way screw 53, a second spring 54, a first magnet 55 and a second magnet 56, wherein the outer sleeve plate 51 is fixedly sleeved on the outer bottom of the outer sleeve 34, the connecting column 52 is fixedly set on the left side of the bottom of the outer sleeve plate 51, the one-way screw 53 is slidably nested along the vertical direction on the outside of the connecting column 52, the second spring 54 is fixedly connected between the connecting column 52 and the one-way screw 53, the first magnet 55 is fixedly set at the bottom end of the one-way screw 53, and the second magnet 56 is located directly below the first magnet 55 and fixedly connected to the inner wall of the device housing 1.

The slide rod 27 is fixedly installed on both sides of one end in the avoidance groove 63, so as to provide auxiliary limiting when the accommodating cylinder 71 slides up and down with the dumping structure 2. At the same time, when the accommodating cylinder 71 dumps the steel slag outward, a rotating fulcrum is provided for the accommodating cylinder 71 to assist in dumping.

[0071] By setting the above structure, the steel slag to be cooled can be placed into the accommodating tube 71 through the top opening of the accommodating tube 71. Due to the obstruction of the mesh plate 72, the steel slag is accumulated on the top of the mesh plate 72. When the top opening of the accommodating tube 71 is sealed, the output end of the water inlet pipe 46 is inserted into the adjacent L-shaped water inlet channel 73, and the input end of the exhaust pipe 47 is inserted into the adjacent L-shaped exhaust channel 74. Then, the water pump on the water inlet pipe 46 is started, and the water pump inputs cooling water into the L-shaped water inlet channel 73 through the water inlet pipe 46, and then the cooling is completed. Water enters the bottom of the inner cavity of the containing tube 71 and forms a water flow to rush towards the steel slag on the top of the mesh plate 72 under the restriction of the holes on the mesh plate 72. The water flow cools the steel slag after contacting the steel slag. The generated water vapor enters the exhaust pipe 47 through the L-shaped exhaust channel 74, and then enters the condensation assembly through the exhaust pipe 47 to be condensed. The condensed water is returned to the water tank for reuse, and the gas is purified and discharged by the gas purification assembly. After the cooling of the steel slag is completed, the dumping structure 2 is used to automatically dump the steel slag in the containing tube 71 during this process.

[0072] When the rotating seat 62 rotates as a whole, the two groups of accommodating cylinders 71 are replaced. During the rotation process, the accommodating cylinder 71 located below the sealed water supply and exhaust steam mechanism 4 slides the pulley 210 installed on the bottom of the accommodating cylinder 71 through the bracket 29 from the surface of the low platform 26 along the lifting guide plate 25 to the surface of the high platform 22. At this time, the accommodating cylinder 71 is lifted up from the rotating seat 62 to a certain height under the auxiliary restriction of the slide grooves 28 symmetrically opened on both sides of the outer end of the accommodating cylinder 71 by the two groups of brackets 29 and the pulley 210 in cooperation with the slide rod 27. The size of the space avoidance groove 63 for installing the accommodating cylinder 71 is larger than the outer diameter of the accommodating cylinder 71. When the accommodating cylinder 71 is completely lifted up from the rotating seat 62, the bottom of the bracket 29 near the inner circle is simultaneously provided. The pulley 210 will slide along the tipping guide plate 24 toward the surface of the tipping platform 23 provided on the inner circle of the high platform 22 under the continuous rotation of the rotating seat 62, and a group of brackets 29 will lift the bottom of the accommodating tube 71 close to the inner circle to a certain height, so that the accommodating tube 71 completely lifted from the rotating seat 62 will be tipped outwards by the pulling of the brackets 29 under the rotation and restriction of the slide bar 27 and the slide groove 28, so that the cooled steel slag in the accommodating tube 71 will be tipped outwards. While tipping, the tipping guide plate 24 and the tipping platform 23 are configured to be serrated, so that the pulley 210 can have a frequent shaking effect when rotating on the surface, so that the steel slag in the accommodating tube 71 can be shaken and poured out, thereby improving the efficiency of tipping.

[0073] During the next movement, the receiving tube 71 on the other side will be in the original tilted state. As the rotating seat 62 rotates, the receiving tube 71 will be reset under the pulling action of the bracket 29. The pulley 210 at the bottom of the bracket 29 moves from the tilting platform 23 to the surface of the tilting guide plate 24 and slides to the surface of the low platform 26 along with the lifting guide plate 25. At this time, the bracket 29 will stand up the receiving tube 71 again and shrink it into the rotating seat 62 and add steel slag inside, so as to cool it down when it reaches below the sealed water supply and exhaust mechanism 4.

[0074] The power transmitted from the first driving mechanism 3 to the synchronous shifting mechanism 6 is used to automatically dump the cooled slag in the accommodating tube 71 while shifting the accommodating tube 71 .

[0075] Example 2

[0076] The present invention also discloses a method for collecting and recovering steam from an industrial cooling tower, which specifically comprises the following steps:

[0077] S1. Put the steel slag to be cooled into the right accommodating tube 71 through the top opening of the right accommodating tube 71, start the driving motor 32, and after the driving motor 32 is started, the reciprocating screw 31 is driven to rotate continuously. When the reciprocating screw 31 rotates, the square driving column 41 is driven to rotate through the square driving groove 33. When the square driving column 41 rotates, the dial plate 43 is driven to rotate through the rotating disk 42;

[0078] S2, when the reciprocating screw 31 rotates, it drives the outer sleeve 34 to descend. When the outer sleeve 34 descends, it drives the inner sleeve 36 to descend through the first spring 35, and drives the connecting column 52 to descend through the outer sleeve plate 51. When the inner sleeve 36 descends, it drives the rotating disk 42 to descend synchronously. When the connecting column 52 descends, it drives the first magnet 55 to descend through the second spring 54 and the one-way screw 53. In this process, the one-way screw 53 drives the threaded sleeve 64 to rotate, and due to the limitation of the overrunning clutch, the rotating seat 62 does not rotate;

[0079] S3, when the outer sleeve 34 descends to a first threshold, the sealing ring 44 fits against the top of the adjacent accommodating tube 71 and cooperates with the rotating disk 42 to close the top opening of the accommodating tube 71. At this time, the output end of the water inlet pipe 46 is inserted into the adjacent L-shaped water inlet channel 73, and the input end of the exhaust pipe 47 is inserted into the adjacent L-shaped exhaust channel 74. Then, the water pump on the water inlet pipe 46 is started, and the water pump inputs cooling water into the L-shaped water inlet channel 73 through the water inlet pipe 46. Then, the cooling water enters the bottom of the inner cavity of the accommodating tube 71 and forms a water flow to rush to the steel slag on the top of the mesh plate 72 under the restriction of the holes on the mesh plate 72;

[0080] S4, the water flow contacts the steel slag to cool the steel slag, and the generated water vapor enters the exhaust pipe 47 through the L-shaped exhaust passage 74, and then enters the condensation assembly through the exhaust pipe 47 to be condensed, and the condensed water is returned to the water tank for reuse, and the gas is purified and discharged by the gas purification assembly. In this process, the steel slag to be cooled is added to the left receiving cylinder 71;

[0081] S5. During the process of cooling the steel slag by water flow, the water flow also pushes the steel slag, thereby causing the steel slag to move upward. After the steel slag moves upward, it contacts the continuously rotating paddle 43, and the paddle 43 paddles the steel slag, thereby causing the steel slag to be cooled more quickly.

[0082] S6. Since the sealing ring 44 is attached to the top of the adjacent accommodating tube 71, the inner sleeve 36 cannot continue to descend due to the obstruction of the accommodating tube 71. Subsequently, as the outer sleeve 34 continues to descend, the first spring 35 is compressed, and the reciprocating screw 31 continues to drive the first magnet 55 to descend through the outer sleeve plate 51, the connecting column 52, the one-way screw 53 and the second spring 54.

[0083] S7, when the outer sleeve 34 descends to a second threshold, the first magnet 55 contacts the second magnet 56, and the outer sleeve 34 moves to the bottom of the reciprocating thread on the outer side of the reciprocating screw 31. As the reciprocating screw 31 continues to rotate, the outer sleeve 34 moves upward and resets. During this process, since the first magnet 55 is attracted by the second magnet 56, the one-way screw 53 does not rise with the outer sleeve 34, and the second spring 54 is continuously stretched.

[0084] S8, when the outer sleeve 34 rises to a third threshold, the compressed first spring 35 is restored, and the slag inside the accommodating tube 71 is cooled. Subsequently, as the outer sleeve 34 continues to rise, the sealing ring 44 drives the output end of the water inlet pipe 46 to rise inside the L-shaped water inlet channel 73, and drives the input end of the exhaust pipe 47 to rise inside the L-shaped exhaust channel 74;

[0085] S9, when the rising distance of the outer sleeve 34 reaches the fourth threshold, the output end of the water inlet pipe 46 moves out from the inner side of the L-shaped water inlet channel 73, and the input end of the exhaust pipe 47 moves out from the inner side of the L-shaped exhaust channel 74. At the same time, the second spring 54 is stretched to the extreme value. Subsequently, as the outer sleeve 34 continues to rise, the outer sleeve 34 drives the one-way screw 53 to rise through the outer sleeve plate 51, the connecting column 52 and the second spring 54, and the one-way screw 53 drives the first magnet 55 to separate from the second magnet 56. At this time, the stretched second spring 54 drives the one-way screw 53 to move up and reset. During the one-way screw 53 moving up, it drives the threaded sleeve 64 to rotate. At this time, the threaded sleeve 64 drives the rotating seat 62 to rotate, thereby enabling the two slag containing mechanisms 7 to be replaced, that is, the containing barrel 71 containing the cooled slag is transferred to the feeding and discharging station, and the containing barrel 71 containing the slag to be cooled is transferred to the cooling station.

[0086] S10, when the rising distance of the outer sleeve 34 reaches the fifth threshold, the outer sleeve 34 moves to the reciprocating top outside the reciprocating screw 31, and then as the reciprocating screw 31 continues to rotate, the outer sleeve 34 moves down again. During this process, the dumping structure 2 is used to automatically dump the slag in the containing tube 71.

[0087] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.

An industrial cooling tower steam collection and recovery processing system according to any one of claims 1 to 9, characterized in that: The invention also includes a method for collecting and recovering steam from an industrial cooling tower, the method specifically comprising the following steps: S1. Put the steel slag to be cooled into the right accommodating tube (71) through the top opening of the right accommodating tube (71), start the driving motor (32), and after the driving motor (32) is started, it drives the reciprocating screw (31) to rotate continuously. When the reciprocating screw (31) rotates, it drives the square driving column (41) to rotate through the square driving groove (33). When the square driving column (41) rotates, it drives the dial plate (43) to rotate through the rotating disk (42); S2, when the reciprocating screw (31) rotates, the outer sleeve (34) is driven to descend. When the outer sleeve (34) descends, the inner sleeve (36) is driven to descend through the first spring (35), and the connecting column (52) is driven to descend through the outer sleeve plate (51). When the inner sleeve (36) descends, the rotating disk (42) is driven to descend synchronously. When the connecting column (52) descends, the first magnet (55) is driven to descend through the second spring (54) and the one-way screw (53). During this process, the one-way screw (53) drives the threaded sleeve (64) to rotate, and due to the limitation of the overrunning clutch, the rotating seat (62) does not rotate; S3, when the outer sleeve (34) descends to a first threshold, the sealing ring (44) fits against the top of the adjacent accommodating tube (71) and cooperates with the rotating disk (42) to close the top opening of the accommodating tube (71). At this time, the output end of the water inlet pipe (46) is inserted into the adjacent L-shaped water inlet channel (73), and the input end of the exhaust pipe (47) is inserted into the adjacent L-shaped exhaust channel (74). Then, the water pump on the water inlet pipe (46) is started, and the water pump inputs cooling water into the L-shaped water inlet channel (73) through the water inlet pipe (46). Then, the cooling water enters the bottom of the inner cavity of the accommodating tube (71) and forms a water flow to rush toward the steel slag on the top of the mesh plate (72) under the restriction of the holes on the mesh plate (72); S4, the water flow contacts the steel slag to cool the steel slag, and the generated water vapor enters the exhaust pipe (47) through the L-shaped exhaust passage (74), and then enters the condensation assembly through the exhaust pipe (47) to be condensed, and the condensed water is returned to the water tank for reuse, and the gas is purified by the gas purification assembly and discharged. In this process, the steel slag to be cooled is added to the left receiving cylinder (71); S5. During the process of cooling the steel slag by the water flow, the water flow also pushes the steel slag, thereby causing the steel slag to move upward. After the steel slag moves upward, it comes into contact with the continuously rotating paddle (43), and the paddle (43) paddles the steel slag, thereby causing the steel slag to be cooled more quickly. S6. Since the sealing ring (44) is attached to the top of the adjacent accommodating tube (71), the inner sleeve (36) cannot continue to descend due to the obstruction of the accommodating tube (71). Subsequently, as the outer sleeve (34) continues to descend, the first spring (35) is compressed, and at the same time, the reciprocating screw (31) continues to drive the first magnet (55) to descend through the outer sleeve plate (51), the connecting column (52), the one-way screw (53) and the second spring (54); S7, when the outer sleeve (34) descends to a second threshold, the first magnet (55) contacts the second magnet (56), and the outer sleeve (34) moves to the bottom of the reciprocating thread on the outer side of the reciprocating screw (31). Subsequently, as the reciprocating screw (31) continues to rotate, the outer sleeve (34) moves upward and resets. During this process, since the first magnet (55) is attracted by the second magnet (56), the one-way screw (53) does not rise with the outer sleeve (34), and the second spring (54) is continuously stretched; S8, when the rising distance of the outer sleeve (34) reaches the third threshold value, the compressed first spring (35) is restored, and the steel slag inside the accommodating tube (71) is completely cooled. Subsequently, as the outer sleeve (34) continues to rise, the sealing ring (44) drives the output end of the water inlet pipe (46) to rise inside the L-shaped water inlet channel (73), and drives the input end of the exhaust pipe (47) to rise inside the L-shaped exhaust channel (74); S9, when the rising distance of the outer sleeve (34) reaches the fourth threshold value, the output end of the water inlet pipe (46) moves out from the inner side of the L-shaped water inlet channel (73), and the input end of the exhaust pipe (47) moves out from the inner side of the L-shaped exhaust channel (74), and at the same time, the second spring (54) is stretched to an extreme value. Subsequently, as the outer sleeve (34) continues to rise, the outer sleeve (34) drives the one-way screw (53) to rise through the outer sleeve plate (51), the connecting column (52) and the second spring (54), and the one-way screw (53) drives The first magnet (55) is separated from the second magnet (56), and the stretched second spring (54) drives the one-way screw (53) to move upward and reset. The one-way screw (53) drives the threaded sleeve (64) to rotate during the upward movement. At this time, the threaded sleeve (64) drives the rotating seat (62) to rotate, thereby causing the two slag containing mechanisms (7) to be replaced, that is, the containing cylinder (71) containing the cooled slag is transferred to the loading and unloading station, and the containing cylinder (71) containing the slag to be cooled is transferred to the cooling station; S10, when the rising distance of the outer sleeve (34) reaches the fifth threshold value, the outer sleeve (34) moves to the outermost reciprocating position of the reciprocating screw (31), and then as the reciprocating screw (31) continues to rotate, the outer sleeve (34) moves downward again.
