Description

Technical Field

[0001] The invention relates to the technical field of steel wire quenching, and in particular to a steel wire quenching tank with a self-cleaning function. Background Art

[0002] At present, oxide scale is often produced in the field of hot processing of workpieces. If the oxide scale is not removed in time, it will accumulate more and more. In this case, the oxide scale in the quenching tank needs to be cleaned regularly, and most of the cleaning requires human intervention, which is a lot of work.

[0003] Chinese patent announcement number CN207811811U discloses an automatic oxide scale cleaning device, which is used in quenching equipment. The quenching equipment includes a shell and a quenching tank arranged at the lower part of the shell, including a conveying part, a chip removal part and an electronic control part. The conveying part is installed in the quenching tank, and the chip removal part is arranged on the inner side wall of the shell. The conveying part conveys the oxide scale generated in the quenching tank to the chip removal part, and the chip removal part discharges the oxide scale from the quenching equipment. The electronic control part controls the operation and stop of the conveying part and the chip removal part.

[0004] In the above scheme, when cleaning the bottom of the quenching tank, when the hopper shovels up the oxide scale in the collecting tank, the oxide scale at the bottom of the collecting tank may not be completely scraped away. Otherwise, the pressure when the hopper contacts the bottom of the collecting tank will be too high, which will lead to excessive wear between the hopper and the collecting tank. At the same time, the oil in the quenching tank needs to be discharged when scraping off the oxide scale. Otherwise, a large amount of oil will be brought out during the scraping process of the hopper, resulting in unnecessary waste of oil. At the same time, during quenching, the temperature of the newly formed oxide scale is relatively high, which makes the conveyor belt easily damaged by the high-temperature oxide scale. Summary of the invention

[0005] In view of the above problems, a steel wire quenching tank with a self-cleaning function is provided. The tank body is set as a semicircular shell structure, and an opening is opened in the upper part of the tank body for the basket with steel wire to descend. By sliding the sliding rod set on the salvage plate, when the hoisting unit hoists the steel wire for quenching, the total length of the salvage plate and the sliding rod is reduced, so that the size of the opening becomes larger, thereby avoiding collisions caused by shaking during the hoisting process. At the same time, during the salvage process of the salvage plate, when the salvage plate is rotated to a vertical state, the sliding rod slidably set on the salvage plate pops out, and the sliding rod extends the height direction of the salvage plate, thereby increasing the salvage plate's capacity to accommodate the oxide scale at the bottom of the tank body, thereby increasing the salvage plate's single salvage volume of the oxide scale at the bottom of the tank body.

[0006] In order to solve the problems of the prior art, the present invention provides a steel wire quenching tank with a self-cleaning function, comprising a tank body; the tank body is a horizontally placed semicircular shell structure, and an opening is provided at the upper part of the tank body, and a discharge position and a loading position are respectively provided on both sides of the opening, and the height of the discharge position is lower than the height of the loading position, and a salvage unit for salvaging the oxide scale at the bottom of the tank body is provided in the tank body, and the salvage unit comprises a salvage plate arranged at the bottom of the tank body and rotating around the axis of the tank body, a sliding rod is provided at the upper part of the salvage plate and slides along the height direction of the salvage plate, and the sliding rod has a highest position and a lowest position on its own moving path, and a float is fixedly provided on the upper part of the sliding rod, and during salvage, the salvage plate rotates from the loading position to the unloading position, and when the salvage plate is at the loading position, the sliding rod is at the lowest position, and when the salvage plate rotates to a vertical state, the sliding rod pops out and rises to the highest position.

[0007] Preferably, a sliding groove is provided on one side of the salvage plate facing the unloading position, and a sliding plate is fixedly provided at the bottom of the float along the height direction of the salvage plate, and the sliding plate extends into the sliding groove and slidably cooperates with the sliding groove.

[0008] Preferably, an air filling groove is provided on the upper portion of the salvage plate, the sliding rod is slidably arranged on the air filling groove, and a pneumatic unit interconnected with the air filling groove is arranged on one side of the salvage plate.

[0009] Preferably, the pneumatic unit includes a connecting pipe arranged on one side of the inflation tank, and a reversing valve is arranged on the end of the connecting pipe away from the inflation tank. The reversing valve has two interfaces, one of which is connected to the outside world, and the other interface is provided with an air pump.

[0010] Preferably, a swing arm is rotatably arranged in the tank body, a telescopic rod is slidably arranged at the lower part of the swing arm along the extension direction of the swing arm, the telescopic rod is hydraulically driven, and the telescopic rod is fixedly connected to the upper part of the salvage plate.

[0011] Preferably, a discharge unit is arranged around the trough body, and the discharge unit comprises a rotating ring rotating around the trough body, a plurality of receiving grooves are arranged on the rotating ring, a receiving plate is hinged on the receiving groove, and a filter hole is opened on the receiving plate.

[0012] Preferably, a reel is provided on the upper portion of the receiving plate, a traction rope is wound inside the reel, and an end portion of the traction rope is fixedly connected to the upper portion of the receiving plate.

[0013] Preferably, a receiving box for receiving the falling oil is provided below the rotating ring, and the receiving box is an annular shell structure with a notch, and the notch is located directly below the upper material position, and the oxide scale received by the receiving plate is discharged from the notch.

[0014] Preferably, a reflux pipe is provided between the tank body and the receiving box to connect the two, and a pump body is provided on the reflux pipe, and the pump body pumps the oil in the receiving box into the tank body.

[0015] Preferably, a slope is provided at the unloading position, a conveyor belt is rotatably provided above the slope, cleaning brushes are evenly provided on the conveyor belt, and a lifting unit for driving the conveyor belt to move in a vertical direction is provided on the upper part of the conveyor belt.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention sets the tank body as a semicircular shell structure, and opens an opening in the upper part of the tank body for the basket with steel wire to descend. By sliding the sliding rod set on the salvage plate, when the hoisting unit hoists the steel wire for quenching, the total length of the salvage plate and the sliding rod is reduced, so that the size of the opening becomes larger, thereby avoiding collisions caused by shaking during the hoisting process. At the same time, during the salvage process of the salvage plate, when the salvage plate is rotated to a vertical state, the sliding rod slidably set on the salvage plate pops out, and the sliding rod extends the height direction of the salvage plate, thereby increasing the salvage plate's capacity to accommodate the oxide scale at the bottom of the tank body, thereby increasing the salvage plate's single salvage volume of the oxide scale at the bottom of the tank body.

[0018] 2. By setting a pneumatic unit, the reversing valve can be switched accordingly when the salvage plate is rotated to different positions. When the salvage plate is at the loading position, the inflation groove is connected to the air pump through the reversing valve, but the air pump is in a stopped state at this time, and the outside air cannot flow into the inflation groove. Therefore, the sliding rod on the salvage plate cannot slide on the salvage plate at this time. When the salvage plate rotates from the loading position to the bottom of the tank body, that is, the salvage plate is in a vertical state at this time, the reversing valve is reversed, and the inflation groove is directly connected to the outside through the reversing valve. Because the float arranged on the upper part of the sliding rod can drive the sliding rod to rise under the action of oil, the outside air is discharged into the inflation groove through the reversing valve and the connecting pipe. At this time, the total length of the salvage plate and the sliding rod becomes longer, thereby increasing the single capacity of the salvage plate during salvage.

[0019] 3. When the receiving plate rotates to the unloading position, the reel reels the traction rope, and the receiving plate is in a horizontal state. When the receiving plate is located at the notch of the receiving box, that is, when the receiving plate is directly below the loading position, the reel releases the traction rope, the receiving plate rotates and tilts, and the oxide scale on the receiving plate is discharged from the notch of the receiving box. Since there is a lot of oil remaining on the oxide scale just salvaged, when the rotating ring drives the receiving plate to rotate to the notch of the receiving box, the oil falls into the receiving box through the filter holes on the receiving plate, so that the oil remaining in the oxide scale can be drained as much as possible.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Reference Figure 1 , Figure 2 and Figure 5 : A wire quenching tank with self-cleaning function, comprising a tank body 1; the tank body 1 is a horizontally placed semicircular shell structure, and an opening is provided at the upper part of the tank body 1, and a discharge position and a loading position are respectively provided on both sides of the opening, and the height of the discharge position is lower than the height of the loading position. A salvage unit 3 for salvaging the oxide scale at the bottom of the tank body 1 is provided in the tank body 1, and the salvage unit 3 comprises a salvage plate 31 arranged at the bottom of the tank body 1 and rotating around the axis of the tank body 1, and a sliding rod 32 is slidably provided at the upper part of the salvage plate 31 along the height direction of the salvage plate 31, and the sliding rod 32 has a highest position and a lowest position on its own moving path, and a float 33 is fixedly provided on the upper part of the sliding rod 32. During salvage, the salvage plate 31 rotates from the loading position to the unloading position, and when the salvage plate 31 is at the loading position, the sliding rod 32 is at the lowest position, and when the salvage plate 31 rotates to a vertical state, the sliding rod 32 pops out and rises to the highest position.

[0037] The tank body 1 contains oil for quenching. During the quenching process of the steel wire, the steel wire cools down rapidly after contacting the oil in the tank body 1, and an oxide scale is formed on the outside of the steel wire. The oxide scale is brittle and will fall to the bottom of the tank body 1 after it is formed. After long-term use, the oxide scale at the bottom of the tank body 1 continues to accumulate, causing the volume of the tank body 1 to be continuously compressed by the oxide scale, and eventually causing the tank body 1 to be unable to perform normal quenching operations on the steel wire. In order to avoid the above situation, in the existing quenching operation, the tank body 1 needs to be cleaned regularly. The existing quenching tank body 1 is mostly a cylindrical structure or a rectangular structure. In this way, when cleaning the oxide scale, the oil in the tank body 1 needs to be discharged first, and then the staff enters the bottom of the tank body 1 to clean it. Although the cleaning of the bottom of the tank body 1 can be completed in this way, the quenching efficiency is low and the work intensity of the staff is high. In order to reduce the workload of the staff, some existing quenching tanks are also equipped with salvage units 3. However, since the structure of the tank body 1 still retains the traditional shape and structure, salvage is inconvenient and the structure is complicated. For example, an automatic oxide scale cleaning device disclosed in Chinese patent announcement No. CN207811811 U records a salvage method combining a conveyor belt 12 and a hopper. Through the flexible characteristics of the conveyor belt 12, the conveyor belt 12 can adapt to the shape of the tank body 1. However, during the cleaning process, since the newly formed oxide scale has a certain temperature and the oxide scale has a sharp corner structure, the conveyor belt 12 will be scratched or burned by the oxide scale in the process of driving the hopper to move, and long-term use can easily cause the conveyor belt 12 to break.

[0038] In order to avoid the above situation, the structure of the tank body 1 is optimized, and the structure of the salvage unit 3 is further optimized, so that the salvage unit 3 can still operate normally during the quenching of the steel wire by the tank body 1, and the salvage unit 3 will not hinder the quenching of the steel wire during the salvage operation. The specific structure and working process of the tank body 1 and the salvage unit 3 are as follows:

[0039] A hoisting unit 2 is provided at the upper part of the tank body 1. The hoisting unit 2 includes a hook. The hook is used to hoist a basket with steel wires placed thereon. The steel wires are placed horizontally on the basket. The hoisting unit 2 drives the steel wires to move along the horizontal arrangement direction of the loading position and the unloading position when quenching. The hoisting unit 2 drives the steel wires to be quenched to move horizontally from one side of the loading position to the top of the tank body 1, and lowers the basket with the steel wires after reaching the designated position. The hoisting method can reduce the working space, but during hoisting, the basket with the steel wires will shake slightly. Therefore, when the hoisting unit 2 vertically lowers the basket with the steel wires into the tank body 1, it is necessary to avoid the shaking basket from colliding with the opening side wall of the tank body 1. Therefore, it is necessary to ensure that the opening size of the tank body 1 is large, which leads to a large floor area of ​​the tank body 1. Therefore, when the salvage plate 31 is at the loading position, the sliding rod 32 slidably arranged on the salvage plate 31 is at the lowest position. At this time, the total length formed by the salvage plate 31 and the sliding rod 32 is the smallest, and the extension direction of the total length is parallel to the height direction of the salvage plate 31. In this way, it can be ensured that the salvage plate 31 does not occupy a large amount of opening space when it is at the loading position. The float 33 is lifted up and the sliding rod 32 is lifted up, so that the height of the salvage plate 31 is extended, thereby increasing the capacity of the salvage plate 31 to accommodate the oxide scale at the bottom of the tank body 1, thereby increasing the single salvage amount of the oxide scale at the bottom of the tank body 1 by the salvage plate 31.

[0040] By sliding the sliding rod 32 on the salvage plate 31, when the hoisting unit 2 hoists the steel wire for quenching, the total length of the salvage plate 31 and the sliding rod 32 is reduced, so that the size of the opening becomes larger, thereby avoiding collisions caused by shaking during the hoisting process. At the same time, during the salvage process of the salvage plate 31, when the salvage plate 31 rotates to a vertical state, the sliding rod 32 slidingly set on the salvage plate 31 pops out, and the sliding rod 32 extends the height direction of the salvage plate 31, so that the salvage effect of the salvage plate 31 is better.

[0041] Reference Fig.10A sliding groove 311 is provided on one side of the salvage plate 31 facing the unloading position, and a sliding plate 331 is fixedly provided at the bottom of the float 33 along the height direction of the salvage plate 31. The sliding plate 331 extends into the sliding groove 311 and slidably cooperates with the sliding groove 311.

[0042] The end of the sliding groove 311 away from the sliding plate 331 is chamfered. In this way, when the salvage plate 31 rotates to the unloading position, the oxide scale at the bottom of the tank body 1 can be taken up by the salvage plate 31 and the sliding plate 331, avoiding the sliding rod 32 from directly taking up the oxide scale at the bottom of the tank body 1, ensuring that when the oxide scale is salvaged to the unloading position, the oxide scale located above the salvage plate 31 will not be stuck on the sliding rod 32 and cannot be unloaded.

[0043] Reference Figure 7 and Fig.10 An air filling groove 341 is provided on the upper portion of the salvage plate 31 , and a sliding rod 32 is slidably disposed on the air filling groove 341 . A pneumatic unit 34 which is interconnected with the air filling groove 341 is provided on one side of the salvage plate 31 .

[0044] When the salvage plate 31 is located at the loading position, the pneumatic unit 34 is closed, and the inflation groove 341 is disconnected from the outside. When the salvage plate 31 is in a vertical state, the pneumatic unit 34 is opened, and the inflation groove 341 is connected to the outside.

[0045] Reference Fig. 9 The pneumatic unit 34 includes a connecting pipe 342 arranged on one side of the inflation groove 341, and a reversing valve 343 is arranged on the end of the connecting pipe 342 away from the inflation groove 341. The reversing valve 343 has two interfaces, one of which is connected to the outside, and the other interface is provided with an air pump 344.

[0046] When the salvage plate 31 is in the loading position, the inflation groove 341 is connected to the air pump 344 through the reversing valve 343, but the air pump 344 is in a stopped state at this time, and the outside air cannot flow into the inflation groove 341, so the sliding rod 32 located on the salvage plate 31 cannot slide on the salvage plate 31 at this time. When the salvage plate 31 rotates from the loading position to the bottom of the tank body 1, that is, the salvage plate 31 is in a vertical state at this time, the reversing valve 343 is reversed, and the inflation groove 341 is directly connected to the outside through the reversing valve 343. Since the float 33 set on the upper part of the sliding rod 32 can drive the sliding rod 32 to rise under the action of oil, the outside air is discharged into the inflation groove 341 through the reversing valve 343 and the connecting pipe 342. At this time, the total length of the salvage plate 31 and the sliding rod 32 becomes longer, thereby increasing the single capacity of the salvage plate 31 during salvage.

[0047] Reference Figure 7 and Fig.11A swing arm 35 is rotatably arranged in the tank body 1, and a telescopic rod 36 is slidably arranged at the lower part of the swing arm 35 along the extension direction of the swing arm 35. The telescopic rod 36 is hydraulically driven and fixedly connected to the upper part of the salvage plate 31.

[0048] The swing center of the swing arm 35 coincides with the center of the tank body 1, and a first rotary driver 37 is horizontally arranged on the side wall of the tank body 1. Two first gears 38 are also arranged in the tank body 1. The two first gears 38 are respectively arranged at the swing center of the swing arm 35 and on the output end of the first rotary driver 37, and the two first gears 38 are meshed with each other. The first rotary driver 37 is preferably a servo motor. When the bottom of the tank body 1 needs to be cleaned, the first rotary driver 37 drives one of the first gears 38 to rotate, thereby rotating the other first gear 38, so that the swing arm 35 drives the telescopic rod 36 to swing, thereby realizing the process of rotating the salvage plate 31 from the loading position to the unloading position. Since only the unloading position has the function of discharging the oxide scale, in order to prevent the salvage plate 31 from pushing out part of the oxide scale at the bottom of the trough body 1 from the loading position when it is reset to the loading position, when the salvage plate 31 rotates to the unloading position and completes the unloading, the telescopic rod 36 is retracted into the swing arm 35 under hydraulic drive. In this way, during the resetting process of the salvage plate 31, the salvage plate 31 will not salvage the oxide scale in the trough body 1, thereby avoiding the situation where the oxide scale is discharged from the loading position.

[0049] Reference Figure 2 , Figure 3 , Fig.12 and Fig.13 A discharge unit 4 is arranged around the tank body 1, and the discharge unit 4 includes a rotating ring 41 rotating around the tank body 1, and a plurality of receiving grooves are arranged on the rotating ring 41, and a receiving plate 42 is hinged on the receiving groove, and a filtering hole is opened on the receiving plate 42.

[0050] The rotating ring 41 can rotate around the trough body 1 and the angle of each rotation is the same as the angle between two adjacent receiving plates 42. A driving unit 43 for driving the rotating ring 41 to rotate is provided at the lower part of the rotating ring 41. The driving unit 43 includes a second rotation driver 431, a gear ring 432, a second gear 433 and an angle sensor. The gear ring 432 is fixedly arranged at the bottom of the rotating ring 41 along the axis of the rotating ring 41. The second gear 433 is arranged on one side of the gear ring 432 and meshes with the gear ring 432. A second rotation driver 431 is arranged at the lower end of the second gear 433. The second rotation driver 431 is used to drive the second gear 433 to rotate. A rotation angle sensor is arranged at the lower part of the gear ring 432. The rotation angle sensor is used to detect the rotation angle of the gear ring 432. It is worth noting that the number of receiving slots is preferably an even number, so that when one of the receiving slots is in the unloading position, there must be a receiving slot located at the notch position of the receiving box 45, which improves the efficiency of discharging oxide scale.

[0051] Reference Figure 8 A reel 44 is provided on the upper portion of the receiving plate 42 , a traction rope 441 is wound inside the reel 44 , and the end of the traction rope 441 is fixedly connected to the upper portion of the receiving plate 42 .

[0052] Reference Figure 3 A receiving box 45 for receiving the falling oil is provided below the rotating ring 41. The receiving box 45 is an annular shell structure with a notch. The notch is located directly below the upper material position. The oxide scale received by the receiving plate 42 is discharged from the notch.

[0053] When the receiving plate 42 rotates to the unloading position, the reel 44 reels the traction rope 441, and the receiving plate 42 is in a horizontal state. When the receiving plate 42 is located at the notch of the receiving box 45, that is, when the receiving plate 42 is located directly below the loading position, the reel 44 releases the traction rope 441, and the receiving plate 42 rotates and tilts, and the oxide scale on the receiving plate 42 is discharged from the notch of the receiving box 45. Since there is a lot of oil remaining on the oxide scale just salvaged, when the rotating ring 41 drives the receiving plate 42 to rotate to the notch position of the receiving box 45, the oil falls into the receiving box 45 through the filter holes on the receiving plate 42, so that the oil remaining in the oxide scale can be drained as much as possible.

[0054] Reference Fig.11 A return pipe 46 is provided between the tank body 1 and the receiving box 45 to connect the two. A pump body 47 is provided on the return pipe 46. The pump body 47 pumps the oil in the receiving box 45 into the tank body 1.

[0055] The pump body 47 continuously injects the oil collected by the receiving box 45 into the tank body 1, thereby ensuring that the oil in the tank body 1 will not suffer a large loss due to cleaning.

[0056] Reference Figure 4-Figure 6 A slope 11 is provided at the unloading position, a conveyor belt 12 is rotatably provided above the slope 11, cleaning brushes 13 are evenly provided on the conveyor belt 12, and a lifting unit 14 for driving the conveyor belt 12 to move in a vertical direction is provided on the upper part of the conveyor belt 12.

[0057] The conveyor belt 12 has a highest position and a lowest position when moving in the vertical direction. Before the receiving plate 42 reaches the unloading position, the conveyor belt 12 is at the highest position, so that the reel 44 that rotates synchronously with the rotating ring 41 will not be blocked by the conveyor belt 12. After the receiving plate 42 rotates to the unloading position, the lifting unit 14 drives the conveyor belt 12 to descend to the lowest position, and the cleaning brush 13 on the conveyor belt 12 cleans the oxide scale remaining on the slope 11. Although the temperature of the oxide scale is high, the conveyor belt 12 does not directly contact the oxide scale, which avoids the conveyor belt 12 from being damaged when cleaning the oxide scale on the slope 11, and prolongs the service life of the conveyor belt 12. After the cleaning is completed, the lifting unit 14 drives the conveyor belt 12 to rise to the highest position, and the cycle is repeated. It is worth noting that the lifting unit 14 is preferably a screw type, which ensures that the speed of the conveyor belt 12 is relatively uniform when lifting and lowering, and the speed is not too fast. It avoids the situation where the conveyor belt 12 contacts the oxide scale on the slope 11 due to inertia.

[0058] Working principle: During hoisting, the basket holding the steel wire will shake slightly. Therefore, when the hoisting unit 2 vertically lowers the basket holding the steel wire into the tank body 1, it is necessary to avoid the shaking basket from colliding with the opening side wall of the tank body 1. Therefore, it is necessary to ensure that the opening size of the tank body 1 is large, which leads to a larger floor space of the tank body 1. Therefore, when the salvage plate 31 is in the loading position, the sliding rod 32 slidably arranged on the salvage plate 31 is in the lowest position. At this time, the total length formed by the salvage plate 31 and the sliding rod 32 is the smallest, and the extension direction of the total length is parallel to the height direction of the salvage plate 31. In this way, it can be ensured that the salvage plate 31 does not occupy more space in the opening when it is in the loading position. The float 33 is lifted up and the sliding rod 32 is lifted up, so that the height of the salvage plate 31 is extended, thereby increasing the capacity of the salvage plate 31 to accommodate the oxide scale at the bottom of the tank body 1, thereby increasing the single salvage amount of the oxide scale at the bottom of the tank body 1 by the salvage plate 31.

[0059] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
