Description

Technical Field

[0001] The present invention relates to the field of heat treatment technology, and in particular to a water-cooling-based steel structure heat treatment tempering device and method. Background Art

[0002] In the modern industrial field, steel structures are widely used in many important industries such as construction, bridges, and machinery manufacturing due to their many advantages such as high strength, good toughness, and reusability. Heat treatment and tempering are key process links to improve the performance of steel structures, and their treatment effect directly determines the final quality and service life of the steel structures.

[0003] However, during the tempering process, especially when the airflow in the tempering furnace fluctuates, the steel structure may be displaced or shaken, which will not only destroy the stability of the tempering process and reduce the tempering quality, but may also cause surface damage and deformation of the steel structure. During the tempering process of the tempering furnace, the temperature in the furnace increases, and the sealing material of the sealing cover expands due to the heat, making it difficult to maintain the stability of the sealing cover itself, thereby reducing the sealing of the tempering furnace. In view of this, we propose a steel structure heat treatment tempering device and method based on water cooling. Summary of the invention

[0004] The object of the present invention is to provide a water-cooled steel structure heat treatment tempering device and method to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides a water-cooled steel structure heat treatment tempering device, comprising a tempering furnace body, one end of which is provided with a sealing cover, the interior of the tempering furnace body is provided with a limiting mechanism for clamping the steel structure, and one side of the limiting mechanism is provided with a smoke exhaust mechanism;

[0006] In the process of sealing the tempering furnace body through the sealing cover, the driving force generated by the limit mechanism gradually increases, and the magnitude of the driving force can control the smoke exhaust volume of the smoke exhaust mechanism. At the same time, the smoke exhaust mechanism ensures the stability of the limit mechanism when clamping the steel structure during operation;

[0007] The tempering furnace body is equipped with a cooling mechanism, which cools the tempering furnace body in an embracing manner. During the cooling process of the tempering furnace body, the low temperature generated is evenly transmitted to the sealing cover and the smoke exhaust mechanism, so that the tempering furnace body maintains stable sealing.

[0008] As a further improvement of the technical solution, a sliding groove for moving the limiting mechanism is provided on the top of the inner cavity of the tempering furnace body, and a pushing block is fixedly connected to the side of the sealing cover close to the tempering furnace body.

[0009] As a further improvement of the technical solution, the limiting mechanism includes a hydraulic lifting rod that moves inside the sliding groove, and the bottoms of both ends of the hydraulic lifting rod are fixedly installed with mechanical clamps that clamp the steel structure, and the end of the hydraulic lifting rod away from the sealing cover is fixedly connected to a compression spring, and a buffer telescopic rod is sleeved inside the compression spring, and a power rod is fixedly connected to the buffer telescopic rod, and the end of the compression spring away from the hydraulic lifting rod is connected to the inner wall of the tempering furnace body;

[0010] When the hydraulic lifting rod moves, it will push the power rod to move synchronously, and in the process of the power rod moving, it will produce a compression effect on the buffer telescopic rod and the compression spring.

[0011] As a further improvement of the present technical solution, the smoke exhaust mechanism includes a push rod fixedly connected to one end of the power rod, one end of the push rod is fixedly connected to a sliding rod, one end of the sliding rod is fixedly connected to a sealing plug, and one side of the sliding rod is slidably connected to the side of the tempering furnace body.

[0012] As a further improvement of the technical solution, a smoke exhaust block is slidably connected to the top of the sealing plug, and a smoke exhaust groove for exhausting smoke is provided on one side of the smoke exhaust block.

[0013] As a further improvement of the technical solution, a smoke exhaust pipe is fixedly connected to the outer wall of the smoke exhaust block, the smoke exhaust pipe is connected to one side of the tempering furnace body, and a filter plate is clamped on the top of the smoke exhaust pipe.

[0014] As a further improvement of the technical solution, the cooling mechanism includes a first cooling cavity fixedly mounted on the tempering furnace body, a delivery pipe is connected through one side of the first cooling cavity, the output of the delivery pipe is connected to the second cooling cavity, and the output end of the second cooling cavity is connected to a cooler, the output end of the cooler is connected to a circulation pump, and the output end of the circulation pump is connected to the first cooling cavity;

[0015] The smoke exhaust mechanism is located between the first cooling cavity and the second cooling cavity, and is used to sense the cold air emitted outward from the first cooling cavity and the second cooling cavity.

[0016] The second object of the present invention is to provide a method for heat treatment and tempering of a steel structure based on water cooling, comprising the following method steps:

[0017] S1. Open the sealing cover, place the steel structure inside the tempering furnace body, and clamp and fix the steel structure using a limiting mechanism;

[0018] S2. In the process of closing the sealing cover, the sealing cover transmits the driving force to the limiting mechanism, and then the limiting mechanism further transmits the power to the smoke exhaust mechanism. Through this process, the limiting mechanism drives the smoke exhaust mechanism to move, thereby realizing the control of the smoke exhaust speed;

[0019] S3. When the tempering furnace body reaches a certain temperature, the cooling mechanism is started to cool the tempering furnace body.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. In the water-cooled steel structure heat treatment tempering device and method, the design of the adjustment plate, transmission plate, inclined block and other components in the smoke exhaust mechanism realizes the precise control of the smoke exhaust volume. The movement of the adjustment plate drives the lifting and lowering of the transmission plate, thereby controlling the blocking degree of the smoke outlet pipe by the blocking rod, thereby synchronously opening and closing the smoke exhaust volume. It can be flexibly adjusted according to the actual needs of the tempering process, ensuring a good gas environment in the tempering furnace, which is conducive to improving the tempering efficiency and quality. In addition, the smoke exhaust mechanism can also ensure the stability of the limit mechanism when clamping the steel structure during operation, preventing the steel structure from displacement or shaking during the tempering process, and further improving the tempering quality of the steel structure.

[0022] The sliding groove arranged on the top of the inner cavity of the tempering furnace body and the pushing block on the sealing cover cooperate with the hydraulic lifting rod and other components in the limiting mechanism, so that the limiting mechanism can stably clamp and fix the steel structure, and can generate controllable driving force during the sealing process. The setting of the compression spring and the buffer telescopic rod in the limiting mechanism can not only provide a certain buffering effect when clamping the steel structure to protect the steel structure from damage, but also play a stabilizing and shock-absorbing effect when the hydraulic lifting rod moves.

[0023] 2. In the water-cooled steel structure heat treatment tempering device and method, a good linkage effect is also formed between the cooling mechanism, the limiting mechanism and the smoke exhaust mechanism. The cooling mechanism cools the tempering furnace body in an embracing manner and evenly transmits the low temperature to the sealing cover and the smoke exhaust mechanism. On the one hand, a stable low-temperature environment helps to maintain the sealing performance of the sealing cover, reduce the sealing failure problem caused by temperature changes, and ensure the sealing of the tempering furnace body;

[0024] On the other hand, the low temperature is transmitted to the smoke exhaust mechanism, so that the various components of the smoke exhaust mechanism operate in a stable temperature environment, reducing the deformation or wear of the components caused by temperature fluctuations, and improving the stability and reliability of the operation of the smoke exhaust mechanism. The stability of the operation of the smoke exhaust mechanism in turn provides better working conditions for the limit mechanism, ensuring that the limit mechanism will not be disturbed by the instability of the smoke exhaust mechanism when clamping the steel structure, further enhancing the stability of the limit mechanism clamping the steel structure.

[0025] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention.

[0040] Example 1

[0041] See also Figure 1 - Figure 8 As shown, this embodiment provides a steel structure heat treatment tempering device based on water cooling, including a tempering furnace body 100, a sealing cover 101 is provided at one end of the tempering furnace, a limiting mechanism 200 for clamping the steel structure is provided inside the tempering furnace body 100, and a smoke exhaust mechanism 300 is provided on one side of the limiting mechanism 200;

[0042] In the process of sealing the tempering furnace body 100 through the sealing cover 101, the driving force generated by the limiting mechanism 200 gradually increases, and the magnitude of the driving force can control the smoke exhaust amount of the smoke exhaust mechanism 300. At the same time, the smoke exhaust mechanism 300 ensures the stability of the limiting mechanism 200 when clamping the steel structure during operation;

[0043] The tempering furnace body 100 is equipped with a cooling mechanism 400, which cools the tempering furnace body 100 in an embracing manner. During the cooling process of the tempering furnace body 100, the low temperature generated is evenly transmitted to the sealing cover 101 and the smoke exhaust mechanism 300, so that the tempering furnace body 100 maintains stable sealing.

[0044] When the present invention uses the tempering furnace main body 100 to temper the steel structure, on the one hand, during the tempering process, especially when the airflow in the tempering furnace fluctuates, the steel structure may be displaced or shaken, which will not only destroy the stability of the tempering process and reduce the tempering quality, but also may cause problems such as surface damage and deformation of the steel structure, resulting in product scrapping and waste of resources. When the smoke exhaust volume is too large, it will take away too much heat, affecting the tempering efficiency; and when the smoke exhaust volume is too small, it will cause waste gas accumulation in the furnace, which will not only cause serious pollution to the working environment, but also have a negative impact on the normal operation of the equipment. Therefore, the smoke exhaust mechanism 300 and the limiting mechanism 200 are used to achieve synchronous opening and closing of the smoke exhaust volume, which can be flexibly adjusted according to the actual needs of the tempering process, thereby ensuring a good gas environment in the tempering furnace, which is conducive to improving the tempering efficiency and quality. In addition, the smoke exhaust mechanism 300 can also ensure the stability of the limiting mechanism 200 when clamping the steel structure during operation, preventing the steel structure from being displaced or shaken during the tempering process, and further improving the tempering quality of the steel structure.

[0045] The size of the sealing cover 101 inserted into the tempering furnace body 100 can be controlled. When the sealing cover 101 is inserted into the tempering furnace body 100 to a certain depth, the locking buckle on the sealing cover 101 can be used to lock the sealing cover 101 and the tempering furnace body 100 to ensure the stability of the sealing cover 101. On the one hand, the size of the sealing cover 101 inserted can control the smoke exhaust volume, which plays a role in synchronously opening and closing the smoke exhaust volume. On the other hand, the sealing cover 101 can adjust the insertion depth of the sealing cover 101 according to the size of the steel structure, so as to adapt to steel structures of different sizes.

[0046] On the other hand, during the tempering process of the tempering furnace, the temperature in the furnace rises, and the sealing material of the sealing cover 101 expands due to the heat, making it difficult to maintain the stability of the sealing cover 101 itself, thereby reducing the sealing performance of the tempering furnace, and also causing uneven distribution of the temperature field in the tempering furnace, so that various parts of the steel structure cannot be tempered evenly, seriously affecting the performance consistency and overall quality of the steel structure. Therefore, the cooling mechanism 400 cools the tempering furnace body 100 in an embracing manner, and evenly conducts the low temperature to the sealing cover 101 and the smoke exhaust mechanism 300. On the one hand, a stable low-temperature environment helps to maintain The sealing performance of the sealing cover 101 is maintained, the sealing failure problem caused by temperature changes is reduced, the sealing of the tempering furnace body 100 is ensured, and the low temperature is transmitted to the smoke exhaust mechanism 300, so that the various components of the smoke exhaust mechanism 300 work in a stable temperature environment, reducing the deformation or wear of the components caused by temperature fluctuations, and improving the stability and reliability of the operation of the smoke exhaust mechanism 300. The stability of the operation of the smoke exhaust mechanism 300 in turn provides better working conditions for the limiting mechanism 200, ensuring that the limiting mechanism 200 will not be disturbed by the instability of the smoke exhaust mechanism 300 when clamping the steel structure;

[0047] When the sealing cover 101 is pulled out from the tempering furnace body 100, the limiting mechanism 200 uses its own resilience to bring the clamped steel structure to the exit position close to the original location of the sealing cover 101. At this time, the operator can use tools to pull out the hydraulic lifting rod 201 and then take out the steel structure. It should be noted that due to the residual temperature in the tempering furnace body 100, in order to avoid burns, the operator must be particularly careful during the operation and must not directly reach into the tempering furnace body 100 to take out the steel structure with bare hands.

[0048] On the basis of the above, the specific structure is disclosed in detail:

[0049] To achieve 100% exhaust of the tempering furnace, Figure 2 - Figure 5As shown, a sliding groove for moving the limiting mechanism 200 is provided at the top of the inner cavity of the tempering furnace body 100, and a pushing block 102 is fixedly connected to the side of the sealing cover 101 close to the tempering furnace body 100. The limiting mechanism 200 includes a hydraulic lifting rod 201 that moves inside the sliding groove, and a mechanical clamp 202 for clamping a steel structure is fixedly installed at the bottom of both ends of the hydraulic lifting rod 201. A compression spring 203 is fixedly connected to the end of the hydraulic lifting rod 201 away from the sealing cover 101, and a buffer telescopic rod 204 is sleeved inside the compression spring 203. A power rod 205 is fixedly connected to the buffer telescopic rod 204, and the end of the compression spring 203 away from the hydraulic lifting rod 201 is connected to the inner wall of the tempering furnace body 100; when the hydraulic lifting rod 201 moves, it will push the power rod 205 to move. The rods 205 move synchronously, and during the movement of the power rod 205, a compression effect is generated on the buffer telescopic rod 204 and the compression spring 203. The smoke exhaust mechanism 300 includes a push rod 301 fixedly connected to one end of the power rod 205, one end of the push rod 301 is fixedly connected to a sliding rod 302, one end of the sliding rod 302 is fixedly connected to a sealing plug 303, and one side of the sliding rod 302 is slidably connected to the side of the tempering furnace body 100, the top of the sealing plug 303 is slidably connected to a smoke exhaust block 304, and one side of the smoke exhaust block 304 is provided with a smoke exhaust groove for exhausting smoke, the outer wall of the smoke exhaust block 304 is fixedly connected to a smoke exhaust pipe 305, the smoke exhaust pipe 305 is connected to one side of the tempering furnace body 100, and a filter plate 306 is clamped on the top of the smoke exhaust pipe 305;

[0050] Therefore, the hydraulic lifting rod 201 moves to push the power rod 205, and the power rod 205 drives the pushing rod 301, the sliding rod 302 and the sealing plug 303 of the smoke exhaust mechanism 300 to move. The sealing plug 303 cooperates with the smoke exhaust block 304 to control the opening of the smoke exhaust groove by changing the relative position, thereby accurately controlling the smoke exhaust volume. The filter plate 306 on the top of the smoke exhaust pipe 305 can effectively filter impurities in the smoke and purify the exhaust gas. The entire smoke exhaust mechanism 300 is linked with the limiting mechanism 200 to adjust the smoke exhaust according to the state of the sealing cover 101, maintain the stability of the gas environment in the furnace, and ensure the smooth progress of the tempering process.

[0051] To achieve normal operation of the components in the tempering furnace body 100, Figure 6 - Figure 8As shown, the cooling mechanism 400 includes a first cooling cavity 401 fixedly mounted on the tempering furnace body 100, a delivery pipe 402 is connected through one side of the first cooling cavity 401, the output of the delivery pipe 402 is connected to the second cooling cavity 403, and the output end of the second cooling cavity 403 is connected to the cooler, the output end of the cooler is connected to the circulation pump 404, and the output end of the circulation pump 404 is connected to the first cooling cavity 401, and the smoke exhaust mechanism 300 is located between the first cooling cavity 401 and the second cooling cavity 403, and is used to sense the cold air emitted outward from the first cooling cavity 401 and the second cooling cavity 403;

[0052] Therefore, the cooling mechanism 400 cools down the tempering furnace body 100 in an embracing manner, and evenly transmits the low temperature to the sealing cover 101 and the smoke exhaust mechanism 300. On the one hand, the stable low temperature environment helps to maintain the sealing performance of the sealing cover 101, reduce the sealing failure problem caused by temperature changes, and ensure the sealing of the tempering furnace body 100. On the other hand, the low temperature is transmitted to the smoke exhaust mechanism 300, so that the various components of the smoke exhaust mechanism 300 work in a stable temperature environment, reducing the deformation or wear of the components caused by temperature fluctuations, and improving the stability and reliability of the operation of the smoke exhaust mechanism 300.

[0053] The second object of the present invention is to provide a method for heat treatment and tempering of a steel structure based on water cooling, comprising the following method steps:

[0054] S1. Open the sealing cover 101, place the steel structure inside the tempering furnace body 100, and clamp and fix the steel structure using the limiting mechanism 200;

[0055] S2. In the process of closing the sealing cover 101, the sealing cover 101 transmits the driving force to the limiting mechanism 200, and then the limiting mechanism 200 further transmits the driving force to the smoke exhaust mechanism 300. Through this process, the limiting mechanism 200 pushes the smoke exhaust mechanism 300 to move, thereby realizing the control of the smoke exhaust speed;

[0056] S3. When the tempering furnace body 100 reaches a certain temperature, the temperature reduction mechanism 400 is started to reduce the temperature of the tempering furnace body 100.

[0057] Working principle:

[0058] Turn on the cooler and the circulation pump 404 to allow the coolant to circulate between the first cooling cavity 401, the delivery pipe 402, the second cooling cavity 403 and the cooler, so as to prepare for the cooling of the tempering furnace body 100, place the steel structure to be heat treated and tempered at a suitable position in the tempering furnace body 100, and prepare to close the sealing cover 101;

[0059] The sealing cover 101 is pushed toward the tempering furnace body 100, and the sealing cover 101 can be inserted into the tempering furnace body 100. The depth of the sealing cover 101 inserted into the tempering furnace body 100 determines the smoke exhaust size. When the sealing cover 101 is inserted to a specific depth, the sealing cover 101 can be locked with the tempering furnace body 100 by means of a lock buckle on the sealing cover 101.

[0060] The pushing block 102 on the side of the sealing cover 101 close to the tempering furnace body 100 is gradually inserted into the inner cavity of the tempering furnace body 100. As the pushing block 102 is inserted, the pushing block 102 pushes the hydraulic lifting rod 201 to move in the sliding groove in the direction away from the sealing cover 101. When the hydraulic lifting rod 201 moves, it drives the mechanical clamps 202 at the bottom of both ends to move synchronously, and the mechanical clamps 202 begin to clamp the steel structure. (The mechanical clamps 202 are common in the prior art. When the mechanical clamps 202 clamp the steel structure, they drive the clamping blocks on both sides to move toward or away from each other through their own hydraulic driving force, thereby clamping or releasing the steel structure.) During the movement of the hydraulic lifting rod 201, the end thereof away from the sealing cover 101 pushes the power rod 205 to move synchronously, and the power rod 205 compresses the buffer telescopic rod 204 and the compression spring 203. As the sealing cover 101 continues to close, the driving force generated by the limiting mechanism 200 gradually increases.

[0061] The movement of the power rod 205 drives the fixedly connected push rod 301 to move, the push rod 301 drives the sliding rod 302, and the sliding rod 302 drives the sealing plug 303 to move. During the movement of the sealing plug 303, the top of the sealing plug 303 slides relative to the smoke exhaust block 304. When the sealing plug 303 moves to a suitable position, the smoke exhaust groove provided on the smoke exhaust block 304 is connected to the interior of the tempering furnace body 100. At this time, the smoke in the tempering furnace body 100 can enter the smoke exhaust block 304 through the smoke exhaust groove, and the smoke enters the smoke exhaust block 304 through the smoke exhaust block 304. The smoke enters the smoke exhaust pipe 305 fixedly connected to its outer wall, and the filter plate 306 clamped on the top of the smoke exhaust pipe 305 filters the smoke and then discharges it. The driving force generated by the limiting mechanism 200 controls the moving distance of the power rod 205, thereby controlling the position of the sealing plug 303 and other components in the smoke exhaust mechanism 300, and synchronously opens and closes the smoke exhaust volume. At the same time, during the operation of the smoke exhaust mechanism 300, the interaction between the various components ensures the stability of the limiting mechanism 200 when clamping the steel structure;

[0062] The tempering furnace body 100 is started, and the steel structure clamped on the limiting mechanism 200 is subjected to heat treatment and tempering. During the tempering process, the cooling mechanism 400 continues to work, and the coolant in the first cooling cavity 401 cools the tempering furnace body 100 in a surrounding manner. After the coolant absorbs the heat emitted by the tempering furnace body 100, it enters the second cooling cavity 403 through the delivery pipe 402, and then is output from the second cooling cavity 403 to the cooler for cooling. The cooled coolant is re-delivered back to the first cooling cavity 401 through the circulation pump 404, and the cycle is repeated. During the process of cooling the tempering furnace body 100, the low temperature is evenly transmitted to the sealing cover 101 and the smoke exhaust mechanism 300 through heat conduction, so as to ensure that the tempering furnace body 100 maintains stable sealing and ensure the effect of the tempering treatment;

[0063] When the tempering treatment of the steel structure is completed, the tempering furnace body 100 is closed, and the sealing cover 101 is opened. The sealing cover 101 drives the pushing block 102 to move outward. At this time, the compression spring 203 releases the elastic potential energy and pushes the hydraulic lifting rod 201 to move toward the sealing cover 101. The mechanical clamp 202 releases the clamping of the steel structure, the treated steel structure is taken out, and the inside of the tempering furnace body 100 is cleaned. At the same time, the operation of the cooler and the circulating pump 404 can be stopped as needed.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
