Description

Technical Field

[0001] The invention relates to the technical field of rotary kilns, and more particularly to a rotary kiln cooling device. Background Art

[0002] Rotary kilns are widely used in many production industries such as new energy, metallurgy, chemical industry, environmental protection, etc. to carry out mechanical, physical or chemical treatment of solid materials. In the process of preparing solid materials, rotary kilns need to quench the clinker after heating and roasting, that is, quickly cool the clinker to improve the quality of the clinker, increase the grindability of the clinker, and reduce the temperature of the clinker.

[0003] At present, during the cooling process of the clinker in the rotary kiln, the cooling fan is placed at the bottom of the cooling section of the rotary kiln, and the clinker is accumulated at the cooling section. The cooling section cylinder of the rotary kiln is cooled by air cooling. However, this method will result in uneven cooling. In view of this problem, the staff has improved the cooling method of the rotary kiln, and the cooling section cylinder of the rotary kiln is cooled by a fan or water cooling. However, during the water cooling process, due to the high temperature of the cooling section cylinder of the rotary kiln, a large amount of steam will be generated when the cooling water is sprayed on the outside of the cylinder. Under normal pressure, the steam density generated by the cooling water is less than the air density. Therefore, the steam flows upward at the moment of generation, and the cooling water collides with the generated steam downward, resulting in the cooling water being blocked by the steam when it reaches the cooling section cylinder of the rotary kiln, and the cooling water has exchanged heat with the steam before it contacts the cooling section of the rotary kiln, thereby affecting the spraying and cooling effect of the cooling section of the rotary kiln. Summary of the invention

[0004] In view of the shortcomings of the prior art, an object of the present invention is to provide a rotary kiln cooling device.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a rotary kiln cooling device, comprising a main body component, a closing component installed on the top of the main body component, a water cooling component and a material turning component arranged inside the closing component, and a water spraying component connected to the water cooling component.

[0006] Among them, the main component includes a bracket and a cylinder rotatably connected to the top of the bracket, a clinker storage is installed at the top of the bracket and at one end of the cylinder, a waste heat recovery component is installed at the top of the bracket and at one side of the clinker storage, the waste heat recovery component is connected to the clinker storage, and a feed port is opened at the end of the cylinder away from the clinker storage.

[0007] The closed component includes a closed box disposed between the cylinder body and the clinker storage bin, and a connecting sleeve penetrating through the interior of the closed box. One end of the connecting sleeve is connected to one end of the cylinder body, and the other end of the connecting sleeve communicates with the clinker storage bin. Two air-cooling mechanisms for air cooling are symmetrically installed on both sides of the closed box.

[0008] There are two groups of the water-cooling components, and the two groups of water-cooling components are respectively installed on the inner wall of the closed box. Fixed frames are installed on the opposite sides of the two groups of water-cooling components. Three first connecting pipes are arranged between the two fixed frames. Two second connecting pipes are communicated at both ends of each first connecting pipe. A third connecting pipe is communicated between the bottoms of the two second connecting pipes. Among them, the first connecting pipe, the corresponding third connecting pipe, and the corresponding two second connecting pipes cooperate to form a "mouth"-shaped pipeline. The three groups of "mouth"-shaped pipelines are sleeved outside the connecting sleeve. Nozzles are installed at the positions of each first connecting pipe, second connecting pipe, and third connecting pipe facing the connecting sleeve. Connecting flanges are arranged above each fixed frame, and the connecting flanges communicate with the three second connecting pipes below the corresponding fixed frames.

[0009] The present invention is further configured as follows: Each of the two groups of water-cooling components includes a connecting frame installed on the inner side wall of the fixed frame. Sliding seats are slidably connected to the opposite sides of the two connecting frames. The two sliding seats are arranged corresponding to the two fixed frames, and the sliding seats are connected to the corresponding fixed frames.

[0010] The present invention is further configured as follows: Chute grooves are formed on the opposite sides of the two connecting frames. Pulleys are rotatably connected to the sides of the sliding seats close to the corresponding connecting frames. The pulleys are slidably connected inside the corresponding chute grooves. Two displacement cylinders are symmetrically installed on the side of the closed box close to the cylinder body. The two displacement cylinders are arranged corresponding to the two sliding seats. The piston rods of the two displacement cylinders penetrate into the interior of the closed box and are connected to the corresponding sliding seats.

[0011] By adopting the above technical solution, the first connecting pipe, the corresponding third connecting pipe, and the corresponding two second connecting pipes cooperate to form a "mouth"-shaped pipeline. The nozzles on each group of "mouth"-shaped pipelines spray onto the outer wall of the connecting sleeve, and the entire outer wall of the connecting sleeve comes into contact with the cooling water, so as to achieve the purpose of all-round cooling, increase the spraying range of the nozzles and the cooling area of the connecting sleeve, enabling the clinker accumulated below the interior of the connecting sleeve to be cooled simultaneously. The steam flowing horizontally through the connecting sleeve comes into contact with the cooling water in a surrounding spraying manner, so that the steam can be dispersed by the cooling water sprayed comprehensively, alleviating the impact between the steam and the cooling water, and further improving the cooling effect of the connecting sleeve and the clinker. By extending and retracting the piston rod of the displacement cylinder, the slide is driven to move on the corresponding connecting frame, and the slide drives the fixed frame and three groups of "mouth"-shaped pipes to move horizontally outside the connecting sleeve, which not only makes the condensed water on the first connecting pipe be shaken off, but also further increases the spraying area of ​​the nozzle, avoiding the situation where the cooling water is not directly sprayed on some parts of the outer wall of the connecting sleeve to cause cooling dead corners.

[0012] The present invention is further configured as follows: the material turning assembly includes a driving motor installed on one side of the clinker bin, the output end of the driving motor is connected to a rotating shaft, the end of the rotating shaft away from the driving motor passes through the clinker bin and extends to the interior of the connecting sleeve, the outer wall of the connecting sleeve is rotatably connected to a cross base plate, the cross base plate is coaxially arranged with the connecting sleeve, the rotating shaft is connected to the midpoint of the side wall of the cross base plate, and four first arc plates are equidistantly surrounded and slidably connected to the side of the cross base plate away from the rotating shaft.

[0013] The present invention is further configured as follows: an adjusting cylinder is arranged on the side of the cross base plate away from the rotating shaft, the piston rod of the adjusting cylinder is connected to the cross base plate, four connecting plates are equidistantly connected to the outer wall of the cylinder body of the adjusting cylinder, the four connecting plates correspond to four first arc plates, and a hinged plate is hinged between the connecting plate and the corresponding first arc plates.

[0014] The present invention is further configured as follows: each of the first arc-shaped plates is connected to a connecting column at one side away from the regulating cylinder, and a second arc-shaped plate is connected to the connecting column at one side away from the corresponding first arc-shaped plate.

[0015] The present invention is further configured as follows: four slide rails are equidistantly connected to the outer wall of the cylinder body of the regulating cylinder and one end away from the cross base plate, the four slide rails are arranged corresponding to the four first arc plates, and the side walls of the four slide rails are provided with limiting grooves along the sliding direction of the corresponding first arc plates, and a limiting column is installed at one end of each of the first arc plates close to the corresponding slide rail, and the limiting column is inserted into the inside of the corresponding limiting groove.

[0016] The present invention is further configured as follows: a first annular groove and a second annular groove are formed on the inner side wall of the connecting sleeve, the four ends of the cross base plate are inserted into the second annular groove, and the ends of the four slide rails away from the regulating cylinder are inserted into the first annular groove.

[0017] By adopting the above technical solution, when the clinker enters the interior of the connecting sleeve, the driving motor drives the rotating shaft, the cross base plate and the components connected to the cross base plate to rotate inside the connecting sleeve. At the same time, the adjusting cylinder is used to push the first arc plate and the second arc plate to move toward the inner wall of the connecting sleeve. The second arc plate is attached to the inner wall of the connecting sleeve. The first arc plate and the second arc plate rotate synchronously in the connecting sleeve. The second arc plate first turns up the clinker attached to the inner wall of the connecting sleeve, and the first arc plate extends into the clinker pile to turn out the high-temperature clinker in the clinker pile. After continuous turning, the clinker pile is dispersed to achieve the purpose of contact and heat exchange between the high-temperature clinker and the inner wall of the connecting sleeve.

[0018] The present invention is further configured as follows: the waste heat recovery component includes a heat exchange cylinder installed on the top of the bracket, and the two ends of the outer wall of the heat exchange cylinder are respectively connected with an intake pipe and an exhaust pipe, the end of the intake pipe away from the heat exchange cylinder is connected with one side of the clinker storage, and a plurality of baffles are equidistantly installed inside the heat exchange cylinder, a sealing plate is installed at the end of the heat exchange cylinder close to the intake pipe, and a heat exchange pipe is connected to the side of the sealing plate close to the heat exchange cylinder, and the heat exchange pipe is penetrated by a plurality of baffles and is arranged horizontally.

[0019] By adopting the above technical scheme, the side wall of the sealing plate is divided into an upper section and a lower section, the water inlet of the heat exchange tube is connected to the upper section of the sealing plate, and the heat exchange tube is connected to the lower section of the sealing plate after circling the inside of the heat exchange tube for one circle, and the external water supply equipment discharges cooling water into the heat exchange tube at the upper section of the sealing plate. When the cooling water flows inside the heat exchange tube, the heat exchange tube is used as a medium to exchange heat with the hot air entering the heat exchange tube. The cooling water inside the heat exchange tube absorbs heat and is discharged and collected through the lower section of the sealing plate. In this process, multiple baffles inside the heat exchange tube cooperate to block the flowing hot air, thereby increasing the heat exchange time between the hot air, the heat exchange tube and the cooling water, and the cooled hot air is discharged through the exhaust pipe.

[0020] The present invention is further configured as follows: a servo motor is installed on the top of the bracket, an output end of the servo motor is connected to a driving gear, an outer wall of the cylinder is sleeved with a driven gear, and the driven gear is meshed with the driving gear.

[0021] By adopting the above technical solution, the servo motor drives the driving gear to rotate, and the driving gear drives the driven gear and the cylinder to rotate when rotating. The slurry that has been homogenized to meet the requirements is sent into the interior of the cylinder by the kiln head feeder and the feed port. Through the continuous rotation of the cylinder and the setting of the tilt angle, it is gradually transported to the direction of the clinker storage and cooled, and finally stored in the clinker storage.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: (1) The first connecting pipe cooperates with the corresponding third connecting pipe and the corresponding two second connecting pipes to form a "mouth"-shaped pipeline. The nozzles on each group of "mouth"-shaped pipelines spray water toward the outer wall of the connecting sleeve, so that the outer wall of the connecting sleeve is in full contact with the cooling water, thereby achieving the purpose of all-round cooling, increasing the spraying range of the nozzles and the cooling area of ​​the connecting sleeve, so that the clinker accumulated at the bottom of the connecting sleeve can be cooled at the same time, and the steam flowing horizontally through the connecting sleeve is in contact with the cooling water by means of a surrounding spray, so that the steam can be dispersed by the fully sprayed cooling water, thereby alleviating the impact between the steam and the cooling water, and further improving the cooling effect of the connecting sleeve and the clinker.

[0023] (2) By extending and retracting the piston rod of the displacement cylinder, the slide is driven to move on the corresponding connecting frame, and the slide drives the fixed frame and three groups of "mouth"-shaped pipes to move horizontally outside the connecting sleeve, which not only causes the condensed water on the first connecting pipe to be shaken off, but also further increases the spraying area of ​​the nozzle, thereby avoiding the situation where the cooling water is not directly sprayed on some parts of the outer wall of the connecting sleeve, causing a cooling dead corner.

[0024] (3) The driving motor drives the turning assembly to rotate as a whole, and uses the adjusting cylinder to push the first arc plate and the second arc plate to move toward the inner wall of the connecting sleeve. The second arc plate is attached to the inner wall of the connecting sleeve. The first arc plate and the second arc plate rotate synchronously in the connecting sleeve.

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application may 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.

[0035] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0036] See also Figure 1-8 , the present invention provides the following technical solutions: Example 1, see Figure 1 and Figure 8A rotary kiln cooling device comprises a main body component 1, the main body component 1 comprises a bracket 11 and a cylinder 12 rotatably connected to the top of the bracket 11, a servo motor 15 is installed on the top of the bracket 11, an output end of the servo motor 15 is connected to a driving gear 14, an outer wall of the cylinder 12 is sleeved with a driven gear 13, the servo motor 15 is used to drive the driving gear 14 to rotate, because the driven gear 13 is meshed with the driving gear 14, therefore, when the driving gear 14 rotates, the driven gear 13 and the cylinder 12 are driven to rotate, a clinker storage 16 is installed on the top of the bracket 11 and at one end of the cylinder 12, a feed port 17 is opened at one end of the cylinder 12 away from the clinker storage 16, the cylinder 12 is gradually lowered from one end of the feed port 17 to the direction of the clinker storage 16, and the homogenization is achieved. The required slurry is fed into the interior of the cylinder 12 by the kiln head feeder and the feed port 17, and is gradually transported toward the clinker storage 16 through the continuous rotation and tilt angle setting of the cylinder 12. In addition, a burner is arranged inside the cylinder 12. The working principle of the rotary kiln burner is to spray fuel at a certain diffusion angle in the fuel channel, transfer a large momentum and angular momentum through the combustion-supporting wind close to the outside, and the internal swirl wind-oil is mixed, the high-speed spiral is propelled, and the axial flow wind beam is ejected at a high speed. The insertion of the axial flow wind speed further enhances the mixing of the fuel and the wind, and a stable combustion flame is formed inside the cylinder 12. The combustion flame dries the transported slurry, so that the moisture inside the slurry is evaporated, and the transported slurry is evaporated to form clinker, and finally the cylinder 12 is used to continue to transport it to achieve the purpose of drying.

[0037] See also Figure 1 and Figure 2 A closing component 2 is installed on the top of the bracket 11. The closing component 2 connects the cylinder 12 and the clinker storage 16. The clinker passes through the closing component 2 and is sent to the internal storage of the clinker storage 16. The specific structure of the closing component 2 is as follows: See also Figure 2The closed component 2 includes a closed box 21 disposed between the cylinder 12 and the clinker storage 16 and a connecting sleeve 22 penetrating the interior of the closed box 21. One end of the connecting sleeve 22 is connected to one end of the cylinder 12, and the other end of the connecting sleeve 22 is connected to the clinker storage 16. The clinker continuously conveyed by the cylinder 12 enters the clinker storage 16 after passing through the connecting sleeve 22. The temperature of the clinker is high during the drying process. In order to improve the quality of the clinker, increase the grindability of the clinker and reduce the temperature of the clinker, two air cooling fans are symmetrically installed on both sides of the closed box 21. The cooling mechanism 6, the air cooling mechanism 6 can be a heat dissipation fan, and the rotation direction of the two groups of air cooling mechanisms 6 is the same, that is, when the high-temperature clinker transfers the heat to the connecting sleeve 22, one group of air cooling mechanisms 6 sucks the external air into the closed box 21 for heat exchange with the connecting sleeve 22, while the other group of air cooling mechanisms 6 discharges the air exchanged with the connecting sleeve 22 from the inside of the closed box 21, thereby achieving the purpose of air circulation, and then dissipating the heat from the connecting sleeve 22, so that the high-temperature clinker can be cooled, and the cooled clinker enters the clinker bin 16 for stacking and storage.

[0038] Embodiment 2: The existing cooling method only uses air cooling to cool down the temperature. In view of this method, the staff adds a water cooling mechanism at the air cooling position, that is, a water cooling pipe and a spray head are set at the air cooling position, and water is supplied to the water cooling pipe and the spray head by a water supply device. The spray head sprays cooling water on the outside of the cylinder of the rotary kiln cooling section to achieve a water cooling effect. During the water cooling process, due to the high temperature of the rotary kiln cooling section cylinder, a large amount of steam will be generated when the cooling water is sprayed on the outside of the cylinder. Under normal pressure, the steam density generated by the cooling water is less than the air density, so the steam will move to the outside of the cylinder at the moment of generation. On this basis, two sets of air cooling mechanisms 6 are horizontally arranged at the cooling section of the rotary kiln to discharge the cooling water horizontally out of the closed box 21. However, due to the large diameter of the connecting sleeve 22, part of the steam still needs to pass through the outer wall of the connecting sleeve 22, and the cooling water impacts the steam passing through the outer wall of the connecting sleeve 22 downward, and the steam and the sprayed cooling water exchange heat with each other, resulting in the cooling water reaching a higher temperature when it contacts the rotary kiln cooling section cylinder. In addition, the material accumulates at the bottom of the connecting sleeve 22, and the spraying effect and cooling effect are not ideal.

[0039] To this end, the water cooling method is further improved in this embodiment. Two groups of water cooling components 3 are arranged inside the closed component 2. The water spray component 4 is connected between the two groups of water cooling components 3. The water spray component 4 is used to spray around the connecting sleeve 22 to achieve the purpose of all-round cooling of the connecting sleeve 22. The specific structures of the water spray component 4 and the water cooling component 3 are as follows: See also Figure 3, two groups of water-cooling components 3 are respectively installed on the inner wall of the closed box 21. Fixed frames 41 are installed on the opposite sides of the two groups of water-cooling components 3. Three first connecting pipes 42 are arranged between the two fixed frames 41. Both ends of each first connecting pipe 42 communicate with two second connecting pipes 43. A third connecting pipe 44 is communicated between the bottoms of the two second connecting pipes 43. Among them, the first connecting pipe 42, the corresponding third connecting pipe 44 and the corresponding two second connecting pipes 43 cooperate to form a "mouth"-shaped pipeline. Three groups of "mouth"-shaped pipelines are sleeved outside the connecting sleeve 22. Nozzles 45 are installed at the positions where each first connecting pipe 42, second connecting pipe 43 and third connecting pipe 44 face the connecting sleeve 22. Connecting flanges 46 are arranged above each fixed frame 41. The connecting flanges 46 are communicated with the three second connecting pipes 43 below the corresponding fixed frames 41. The connecting flanges 46 are communicated with the water outlet end of an external water supply device. The external water supply device can be a water pump, that is, the water inlet end of the water pump is communicated with a water source. The water pump sucks the cooling water and injects it into the "mouth"-shaped pipeline through the water outlet end. The cooling water flows inside the first connecting pipe 42, the corresponding third connecting pipe 44 and the corresponding two second connecting pipes 43 of each group of "mouth"-shaped pipelines, and is sprayed onto the outer wall of the connecting sleeve 22 through the nozzles 45 on each group of "mouth"-shaped pipelines. The entire outer wall of the connecting sleeve 22 is in contact with the cooling water, so as to achieve the purpose of all-round cooling.

[0040] Refer to Figure 3 , both groups of water-cooling components 3 include connecting frames 31 installed on the inner side walls of the fixed frames 41. Slide seats 34 are slidably connected to the opposite sides of the two connecting frames 31. The two slide seats 34 are arranged corresponding to the two fixed frames 41. The slide seats 34 are connected to the corresponding fixed frames 41. By sliding the slide seats 34 on the corresponding connecting frames 31, the fixed frames 41 and the three groups of "mouth"-shaped pipelines are driven to move horizontally outside the connecting sleeve 22, further increasing the spraying area of the nozzles 45, avoiding the situation of cooling dead angles caused by some positions on the outer wall of the connecting sleeve 22 not being directly sprayed with cooling water, and avoiding the situation that the steam above the connecting sleeve 22 impacts with the cooling water, affecting the connecting sleeve 22 and the cooling of the clinker inside the connecting sleeve 22.

[0041] Refer to Figure 3, in this embodiment, sliding grooves 32 are formed on the opposite sides of the two connecting frames 31. A pulley 33 is rotatably connected to one side of the sliding seat 34 close to the corresponding connecting frame 31. The pulley 33 is slidably connected to the inside of the corresponding sliding groove 32. When the sliding seat 34 moves horizontally, the pulley 33 is driven to move inside the corresponding sliding groove 32, thereby limiting the sliding direction of the sliding seat 34. Two displacement cylinders 35 are symmetrically installed on one side of the closed box 21 close to the cylinder body 12. The two displacement cylinders 35 are arranged corresponding to the two sliding seats 34. The piston rods of the two displacement cylinders 35 penetrate into the inside of the closed box 21 and are connected to the corresponding sliding seats 34. The displacement cylinder 35 is used to provide driving force for the corresponding sliding seat 34, that is, by the telescopic movement of the piston rod of the displacement cylinder 35, the sliding seat 34 is driven to move on the corresponding connecting frame 31.

[0042] Specifically, when the clinker reaches the inside of the connecting sleeve 22, the heat of the clinker is transferred to the connecting sleeve 22, and the temperature of the connecting sleeve 22 rises. At this time, through the cooperation of the two groups of air-cooling mechanisms 6, the air inside the closed box 21 circulates, and then part of the steam is discharged. At the same time, an external water supply device supplies cooling water to the positions of the two connecting flanges 46. The cooling water is divided by the three groups of "mouth"-shaped pipes, so that the three groups of "mouth"-shaped pipes are filled with cooling water. And the filled cooling water is sprayed around the outside of the connecting sleeve 22 through the distributed nozzles 45, increasing the spraying range of the nozzles 45 and the cooling area of the connecting sleeve 22, so that the clinker accumulated below the inside of the connecting sleeve 22 can be cooled simultaneously. And the steam flowing horizontally through the connecting sleeve 22 contacts the cooling water in a surrounding spraying manner, so that the steam can be dispersed by the cooling water sprayed comprehensively, alleviating the impact between the steam and the cooling water, and further improving the cooling effect of the connecting sleeve 22 and the clinker.

[0043] In addition, after the steam contacts the cooling water, condensed water will be formed above the outer wall of the first connecting pipe 42. If not processed in time, the condensed water will form scale. Therefore, while the three groups of "mouth"-shaped pipes and the corresponding nozzles 45 cool the connecting sleeve 22 in all directions, through the telescopic movement of the piston rod of the displacement cylinder 35, the sliding seat 34 is driven to move on the corresponding connecting frame 31. The sliding seat 34 drives the fixed frame 41 and the three groups of "mouth"-shaped pipes to move horizontally outside the connecting sleeve 22, which can not only shake off the condensed water on the first connecting pipe 42, but also further increase the spraying area of the nozzles 45, avoiding the situation of cooling dead angles caused by some positions on the outer wall of the connecting sleeve 22 not being directly sprayed with cooling water.

[0044] Embodiment Three, refer to Figure 4 and Figure 5Since the clinker is accumulated inside the connecting sleeve 22 due to the influence of gravity when passing through it, even through all-round spraying and air cooling, the accumulated clinker will still remain high temperature, resulting in the clinker not being completely cooled. Therefore, in order to achieve the purpose of complete cooling, a turning component 5 is provided inside the connecting sleeve 22. During the transportation of the clinker inside the connecting sleeve 22, the turning component 5 turns the accumulated clinker, so that the high-temperature clinker inside the clinker pile is turned out and cooled in contact with the connecting sleeve 22. The specific structure of the turning component 5 is as follows: See also Figure 4 , Figure 5 and Figure 8 The turning assembly 5 includes a driving motor 505 installed on one side of the clinker bin 16, and the output end of the driving motor 505 is connected to a rotating shaft 54. The end of the rotating shaft 54 ​​away from the driving motor 505 passes through the clinker bin 16 and extends to the inside of the connecting sleeve 22. The outer wall of the connecting sleeve 22 is rotatably connected to a cross base plate 55. The cross base plate 55 is coaxially arranged with the connecting sleeve 22. The rotating shaft 54 ​​is connected to the midpoint of the side wall of the cross base plate 55. The driving motor 505 is used to drive the rotating shaft 54 ​​and the cross base plate 55 to rotate. The inner wall of the connecting sleeve 22 is provided with a second annular groove 52. The four ends of the cross base plate 55 are all inserted into the inside of the second annular groove 52. The cross base plate 55 is limited by the second annular groove 52 during rotation to maintain the coaxiality of the cross base plate 55 and the connecting sleeve 22.

[0045] See also Figure 4 and Figure 5 , four first arc-shaped plates 59 are equidistantly surrounded and slidably connected on one side of the cross base plate 55 away from the rotating shaft 54, an adjusting cylinder 56 is arranged on the side of the cross base plate 55 away from the rotating shaft 54, a piston rod of the adjusting cylinder 56 is connected to the cross base plate 55, four connecting plates 57 are equidistantly surrounded and connected to the outer wall of the cylinder body of the adjusting cylinder 56, the four connecting plates 57 correspond to the four first arc-shaped plates 59, a hinge plate 58 is hinged between the connecting plate 57 and the corresponding first arc-shaped plates 59, the adjusting cylinder 56 and the cross base plate 55 are coaxially arranged, the initial state of the adjusting cylinder 56 is an extended state, when the piston of the adjusting cylinder 56 When the rod contracts, it can drive one end of the hinged plate 58 to move. Since the first curved plate 59 slides on the upper limit of the side wall of the cross base plate 55, the other end of the hinged plate 58 applies a thrust to the first curved plate 59. The first curved plate 59 is acted on by the thrust and moves toward the inner wall position of the connecting sleeve 22 on the cross base plate 55. At the same time, the cross base plate 55 drives the four first curved plates 59 to rotate synchronously, so that the first curved plate 59 can turn over the clinker accumulated inside the connecting sleeve 22, so that the high-temperature clinker inside the clinker pile is turned out, so as to achieve the purpose of contact and heat exchange between the high-temperature clinker and the inner wall of the connecting sleeve 22.

[0046] See also Figure 4 and Figure 5 In this embodiment, each first curved plate 59 is connected to a connecting column 501 on one side away from the regulating cylinder 56, and a second curved plate 502 is connected to the connecting column 501 on one side away from the corresponding first curved plate 59. When the first curved plate 59 moves, it drives the corresponding connecting column 501 and the second curved plate 502 to move synchronously. The second curved plate 502 scrapes and turns over the clinker pile attached to the inner wall of the connecting sleeve 22 to avoid incomplete turning of the clinker.

[0047] See also Figure 4 and Figure 5 In this embodiment, four slide rails 53 are equidistantly connected to the outer wall of the cylinder body of the regulating cylinder 56 and one end away from the cross substrate 55. The four slide rails 53 are arranged corresponding to the four first curved plates 59. The side walls of the four slide rails 53 are provided with limiting grooves 503 along the sliding direction of the corresponding first curved plates 59. A limiting column 504 is installed at one end of each first curved plate 59 close to the corresponding slide rail 53. The limiting column 504 is inserted into the corresponding limiting groove 503. In order to avoid the position of the first curved plate 59 away from the cross substrate 55 from being offset, the four slide rails 53 are used to limit the position, that is, when the first curved plate 59 slides on the cross substrate 55, the end of the first curved plate 59 away from the cross substrate 55 drives the limiting column 504 to slide inside the limiting groove 503 provided on the slide rail 53, and the slide rail 53 and the cross substrate 55 cooperate to guide and limit the first curved plate 59.

[0048] See also Figure 4 A first annular groove 51 is formed on the inner wall of the connecting sleeve 22, and one end of the four slide rails 53 away from the adjusting cylinder 56 is inserted into the first annular groove 51. When the adjusting cylinder 56 and the cross base plate 55 rotate, the adjusting cylinder 56 drives the slide rail 53 to rotate synchronously, and the slide rail 53 uses the first annular groove 51 for axial limitation to avoid the slide rail 53 and the first arc plate 59 from being offset. In addition, when the piston rod of the adjusting cylinder 56 is extended or retracted, the slide rail 53 slides inside the first annular groove 51, further limiting and guiding the sliding of the adjusting cylinder 56.

[0049] Specifically, the turning component 5 is in the middle section of the connecting sleeve 22. When the clinker enters the connecting sleeve 22, the clinker first exchanges heat with the connecting sleeve 22, and the heat absorption temperature of the connecting sleeve 22 increases. At this time, water cooling and air cooling are used for the first cooling. When the clinker reaches the position of the turning component 5, the driving motor 505 drives the rotating shaft 54, the cross base plate 55 and the parts connected to the cross base plate 55 to rotate inside the connecting sleeve 22. At the same time, the piston rod of the regulating cylinder 56 contracts, causing the first curved plate 59 and the second curved plate 502 to move toward the inner wall of the connecting sleeve 22, and the second curved plate 502 fits on the connecting sleeve 22. On the inner wall of the connecting sleeve 22, the first curved plate 59 and the second curved plate 502 rotate synchronously in the connecting sleeve 22, the second curved plate 502 first turns up the clinker that is in contact with the inner wall of the connecting sleeve 22, and the first curved plate 59 extends into the clinker pile, thereby turning out the high-temperature clinker in the clinker pile. After continuous turning, the clinker pile is dispersed, and the connecting sleeve 22 is cooled by water cooling and air cooling. As the clinker continues to be transported inside the connecting sleeve 22, the high-temperature clinker reaches the tail end of the connecting sleeve 22 after being turned out and continues to contact the inner wall of the connecting sleeve 22, thereby achieving the purpose of cooling the high-temperature clinker, and finally the cooled clinker enters the clinker bin 16 for storage.

[0050] Example 4, see Figure 1 A waste heat recovery component 7 is installed on the top of the bracket 11 and on one side of the clinker bin 16. The waste heat recovery component 7 is connected to the clinker bin 16. After the clinker reaches the inside of the clinker bin 16, the steam generated by the drying of the clinker, the hot air inside the cylinder 12 and the connecting sleeve 22 enter the waste heat recovery component 7 for waste heat recovery. The specific structure of the waste heat recovery component 7 is as follows: See also Figure 1 , Figure 6 and Figure 7The waste heat recovery component 7 includes a heat exchange cylinder 71 installed on the top of the bracket 11, and the two ends of the outer wall of the heat exchange cylinder 71 are respectively connected with an air inlet pipe 72 and an exhaust pipe 73. The end of the air inlet pipe 72 away from the heat exchange cylinder 71 is connected to one side of the clinker storage 16. A plurality of baffles 76 are equidistantly installed inside the heat exchange cylinder 71. A sealing plate 74 is installed at the end of the heat exchange cylinder 71 close to the air inlet pipe 72. A heat exchange pipe 75 is connected to the side of the sealing plate 74 close to the heat exchange cylinder 71. The heat exchange pipe 75 is penetrated by a plurality of baffles 76 and is horizontally arranged. The steam generated by the drying of the clinker, the hot air in the cylinder 12 and the connecting sleeve 22 enter the heat exchange cylinder 71 through the air inlet pipe 72. The side wall of the sealing plate 74 is divided into an upper section and a lower section. The water inlet of the heat exchange pipe 75 is connected to the sealing plate. The upper section of the heat exchange tube 74 is connected, and the heat exchange tube 75 is connected to the lower section of the sealing plate 74 after circling the inside of the heat exchange tube 71 for one circle. The staff communicates with the heat exchange tube 75 at the upper section of the sealing plate 74 through an external water supply device, and the external water supply device discharges cooling water into the heat exchange tube 75 at the upper section of the sealing plate 74. When the cooling water flows inside the heat exchange tube 75, the heat exchange tube 75 is used as a medium to exchange heat with the hot air entering the heat exchange tube 71. The cooling water inside the heat exchange tube 75 absorbs heat and is discharged and collected through the lower section of the sealing plate 74. In this process, the multiple baffles 76 inside the heat exchange tube 71 cooperate to block the flowing hot air, thereby increasing the heat exchange time between the hot air, the heat exchange tube 75 and the cooling water, and the cooled hot air is discharged through the exhaust pipe 73.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
