Description

Technical Field

[0001] This application relates to the field of steel cord quenching and cooling technology, and in particular to a quenching and cooling device for steel cord. Background Technology

[0002] Steel cord, a finely twisted product made from multiple carefully selected high-carbon steel strands plated with brass and intended for specific applications, involves several precision processes in its production, including dry drawing, electroplating, wet drawing, and twisting. In this series of manufacturing processes, after the dry drawing process, the steel cord must undergo quenching to regain and enhance its strength and ductility, thereby ensuring the smooth progress of subsequent electroplating, wet drawing, and other processes, as well as product quality.

[0003] In the quenching process of steel cord, to ensure that the steel cord meets the tensile strength requirements after water bath quenching, it is necessary to adjust the length of the steel cord immersed in the quenching liquid during the water bath cooling process. Patent announcement number CN218811908U discloses a quenching and cooling device for steel cord. By adjusting the liquid-blocking box in the assembly, the channel formed by the baffle is divided into an upstream side and a downstream side. Rotating the crank rod moves the liquid-blocking box within the channel through a gear and rack structure, thereby adjusting the length of the upstream and downstream sides and achieving adjustment of the immersion length of the steel cord in the quenching liquid.

[0004] However, in related technologies, quenching fluid is drawn from the cooling tank to a cooling platform, where the steel cord is quenched. The quenching fluid is then returned to the cooling tank for recycling. During this process, a large amount of impurities are generated, such as oil, oxides, and chemicals that may remain from the electroplating process. These impurities inevitably mix into the quenching fluid. The accumulation of impurities in the quenching fluid leads to a significant decrease in its purity. This not only directly affects the quenching effect, making it difficult for the mechanical properties and surface quality of the steel cord to meet the expected standards, but may also cause blockages and wear on key components such as pipes and pumps in the quenching and cooling device, thereby threatening the stable operation and efficiency of the entire production line.

[0005] Therefore, how to effectively manage and maintain the purity of quenching fluid and reduce the impact of impurities has become an important technical problem that urgently needs to be solved in the current production of steel cord. Utility Model Content

[0006] The purpose of this application is to provide a quenching and cooling device for steel cord, which solves the problem in the prior art that impurities generated during steel cord quenching circulate with the quenching liquid, affecting the quenching quality.

[0007] To achieve the above objectives / to solve the above technical problems, this application adopts the following technical solution:

[0008] On one hand, this application provides a quenching and cooling device for steel cord, comprising:

[0009] Cooling pool, used to hold quenching liquid;

[0010] A cooling platform, located at the top of the cooling pool, includes a main body. A cooling chamber is located at the top of the main body. A liquid storage chamber is formed inside the main body. An overflow port communicating with the liquid storage chamber is located at the bottom of the cooling chamber. A discharge hole communicating with the cooling chamber is located on one side of the main body. A first filter assembly is detachably installed inside the liquid storage chamber, used to filter the quenching liquid discharged from the overflow port. A second filter assembly is located on the side of the main body near the discharge hole, below the discharge hole, and used to filter the quenching liquid discharged from the discharge hole.

[0011] An adjustment component is movably disposed within the cooling chamber and divides the cooling chamber into a quenching chamber and an overflow chamber. The overflow port is located within the quenching chamber, and the discharge hole is located within the overflow chamber. The adjustment component is used to adjust the length of the quenching chamber.

[0012] The conveying component is connected to the cooling pool and the liquid storage chamber and is used for bidirectional conveying of quenching liquid. The connection between the conveying component and the liquid storage chamber is located on one side of the bottom surface of the first filter assembly.

[0013] This device uses a conveyor to transport quenching fluid from the cooling tank to the storage chamber. As the amount of quenching fluid in the storage chamber increases, it overflows into the quenching chamber within the cooling chamber. Operators complete the quenching of the steel cord within the cooling chamber. During this process, operators can adjust the length of the quenching chamber using an adjusting mechanism to precisely control the immersion length of the steel cord in the quenching fluid. If the length of the quenching chamber is shortened or if quenching fluid overflows due to other reasons, the overflowing fluid flows into the overflow chamber and enters the second filter assembly for purification via a discharge port. The quenching fluid filtered by the second filter assembly is then guided back into the cooling tank, achieving resource recycling. When quenching is complete, the conveyor reverses its operation, transporting the quenching fluid from the storage chamber to the cooling tank. During this process, impurities accumulated in the cooling chamber enter the storage chamber along with the quenching fluid through the overflow port and are effectively filtered by the first filter assembly within the storage chamber, ensuring effective isolation of impurities and allowing the pure quenching fluid to continue to be recycled.

[0014] Optionally, one side of the liquid storage chamber has a filter tank for placing the first filter assembly; the first filter assembly includes a filter frame, one side of which is provided with a frame strip, and the frame strip is sealed to the filter tank.

[0015] During use, the filter frame is placed into the liquid storage chamber through the filter groove. The frame bars on the filter frame are sealed to the filter groove to ensure the integrity of the liquid storage chamber and prevent leakage of the quenching liquid. After quenching, the quenching liquid and impurities flow into the liquid storage chamber together and are filtered by the filter frame. Due to the filtration effect of the filter frame, impurities are trapped on the frame, while the quenching liquid flows back into the cooling pool, thus achieving filtration and purification of the quenching liquid. After the quenching liquid has been recovered, the filter frame can be removed and the impurities cleaned off for future use.

[0016] Optionally, the filter tank has ear plates arranged opposite to each other on both sides, and the frame strip has fixing holes corresponding to the ear plates. The ear plates and the fixing holes are connected by pins.

[0017] To ensure the stability of the filter frame within the liquid storage chamber and prevent problems such as loosening, detachment, or leakage between the frame bars and the filter tank due to hydraulic pressure or other factors, this device features opposing ear plates on both sides of the filter tank. Simultaneously, the frame bars are also equipped with corresponding fixing holes for these ear plates. The frame bars are then secured to the ear plates using pins, further enhancing the stability and sealing of the filter frame.

[0018] Optionally, the main body has a slot on one side; the second filter assembly includes a fixing frame, and a buckle that engages with the slot is provided on one side of the fixing frame, and a filter plate is detachably disposed inside the fixing frame.

[0019] During the quenching process, when the quenching fluid overflows into the overflow chamber and eventually flows into the cooling pool through the outlet, it must first pass through a filter plate located below the outlet. The filter plate intercepts impurities in the quenching fluid, while the pure quenching fluid passes smoothly through the filter plate and flows into the cooling pool. After the quenching fluid is filtered, the impurities on the filter plate need to be cleaned. Because the fixed frame is connected to the main body by snap-fit ​​and slots, the fixed frame can be easily removed from the main body for cleaning.

[0020] Optionally, the adjustment component includes:

[0021] A baffle is provided inside the cooling chamber, dividing the cooling chamber into a quenching chamber and an overflow chamber. The baffle is provided with a connecting sleeve on the side of the overflow chamber.

[0022] An adjusting screw is threaded to the side wall of the main body, with a limiting block at one end. The limiting block is movably connected to the connecting sleeve, and the other end of the adjusting screw passes through the side wall of the main body.

[0023] This device separates the quenching chamber from the overflow chamber using a baffle. The quenching chamber is the main area for quenching the steel cord. During operation, the adjusting screw can be rotated axially along the side wall of the main body. Since the adjusting screw and the baffle are connected by a connecting sleeve and a limiting block, the movement of the adjusting screw will move the baffle along with it. The movement of the baffle changes the length of the quenching chamber, thereby adjusting the immersion length of the steel cord in the quenching liquid. The length of the quenching chamber can be flexibly adjusted according to different quenching requirements and steel cord specifications to ensure optimal quenching results for the steel cord.

[0024] Compared with existing technologies, the beneficial effects achieved by this application are as follows: This application realizes the recycling of quenching liquid in the cooling tank cooling platform through a conveying component. During the quenching process, the length of the quenching chamber can be adjusted by the adjusting component, thereby controlling the immersion length of the steel cord in the quenching liquid. By setting an overflow port and a first filter component, the quenching liquid in the quenching chamber is recovered and filtered. By using a discharge port and a second filter component, the quenching liquid in the overflow chamber is recovered and filtered. This ensures that impurities in the quenching liquid after quenching are completely filtered out, ensuring that the quenching liquid can continue to be recycled.

[0025] Furthermore, the adjustment component in this application adjusts the position of the baffle by adjusting the screw, thereby changing the length of the quenching chamber. Due to the self-locking property of the adjusting screw, the stability of the baffle position can be ensured.

[0026] The significant advantages of this application are as follows: This utility model achieves the recycling and reuse of quenching fluid in the cooling tank cooling platform through a conveying component. This application realizes the recovery and filtration of quenching fluid in the quenching chamber through an overflow port and a first filter assembly. The quenching fluid in the overflow chamber is recovered and filtered through a discharge port and a second filter assembly. This ensures that the quenching fluid in both the quenching chamber and the overflow chamber can be effectively recovered and filtered. This thoroughly removes impurities from the quenching fluid after quenching, thereby ensuring the continuous recycling of the quenching fluid, improving resource utilization efficiency, and significantly enhancing the quality and stability of the quenching process.

[0027] Furthermore, during the quenching process, the length of the quenching chamber can be flexibly adjusted using the adjustment assembly, thereby precisely controlling the immersion length of the steel cord in the quenching liquid. The adjustment assembly uses an adjusting screw to adjust the position of the baffle, achieving flexible changes in the length of the quenching chamber. Not only is the operation simple, but the self-locking feature of the adjusting screw ensures that the baffle remains stable after adjustment. This stability is crucial for maintaining a constant quenching chamber length during the quenching process, thus ensuring precise control of the steel cord's immersion length in the quenching liquid and improving the consistency and reliability of the quenching operation.

[0036] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0037] Example 1

[0038] This embodiment describes a quenching and cooling device for steel cord, referencing... Figure 1The quenching and cooling device for steel cord in this embodiment includes a cooling pool 1 for containing quenching fluid; a cooling platform 2 is provided on the top of the cooling pool 1. The cooling platform 2 includes a main body 21, a cooling chamber 211 is provided on the top of the main body 21, a liquid storage chamber 212 is provided inside the main body 21, an overflow port 213 communicating with the liquid storage chamber 212 is provided at the bottom of the cooling chamber 211, and a discharge hole communicating with the cooling chamber 211 is provided on one side of the main body 21. A first filter assembly 22 is detachably provided in the liquid storage chamber 212, and the first filter assembly 22 is used to filter the quenching fluid discharged from the overflow port 213. A second filter assembly 23 is provided on the side of the main body 21 located on the side of the discharge hole, and the second filter assembly 23 is located below the discharge hole, and is used to filter the quenching fluid discharged from the discharge hole.

[0039] Furthermore, an adjustment component 3 is movably installed within the cooling chamber 211, dividing the cooling chamber 211 into a quenching chamber 2111 and an overflow chamber 2112. The overflow port 213 is located within the quenching chamber 2111, and the discharge hole is located within the overflow chamber 2112. The adjustment component 3 is used to adjust the length of the quenching chamber 2111.

[0040] Furthermore, the cooling tank 1 and the liquid storage chamber 212 are connected by a conveying component 4, which is used for bidirectional conveying of the quenching fluid. In this embodiment, the conveying component 4 uses two pumps with opposite conveying directions, and the connection between the two pumps and the liquid storage chamber 212 is located on one side of the bottom surface of the first filter assembly 22. This ensures that the quenching fluid passing through the cooling chamber 211 and the cooling tank 1 is fully filtered.

[0041] During the quenching process of steel cord, the quenching liquid in the cooling pool 1 is first transported to the storage chamber 212 via the conveyor 4. As the amount of quenching liquid in the storage chamber 212 increases, it overflows through the overflow port 213 into the quenching chamber 211. The operator completes the quenching of the steel cord within the cooling chamber 211. During the process, the operator can adjust the length of the quenching chamber 2111 as needed using the adjusting component 3, thereby precisely controlling the immersion length of the steel cord in the quenching liquid. When the length of the quenching chamber 2111 is shortened or the quenching liquid overflows due to other reasons, the overflowing quenching liquid flows into the overflow chamber 2112 and enters the second filter component 23 for purification through the discharge port. The quenching liquid filtered by the second filter component 23 is then guided back into the cooling pool 1, achieving resource recycling. When quenching is complete, the conveyor 4 reverses its operation, transporting the quenching liquid in the storage chamber 212 to the cooling pool 1. During this process, the impurities accumulated in the cooling chamber 211 will enter the storage chamber 212 along with the quenching fluid through the overflow port 213, and be effectively filtered at the first filter component 22 configured in the storage chamber 212, ensuring that the impurities are effectively isolated, while the pure quenching fluid can continue to be recycled.

[0042] refer to Figure 2In this embodiment, the liquid storage chamber 212 has a filter groove 215 on one side for placing the first filter assembly 22. The first filter assembly 22 includes a filter frame 221, with a frame strip 222 on one side, which is sealed to the filter groove 215. In use, the filter frame 221 is placed into the liquid storage chamber 212 through the filter groove 215. The frame strip 222 on the filter frame 221 is sealed to the filter groove 215 to ensure the integrity of the liquid storage chamber 212 and prevent leakage of the quenching liquid. After quenching, the quenching liquid and impurities in it flow into the liquid storage chamber 212 together and are filtered by the filter frame 221. Due to the filtering effect of the filter frame 221, the impurities are trapped on the filter frame 221, while the quenching liquid flows back into the cooling pool 1, thereby achieving filtration and purification of the quenching liquid. After the quenching liquid is recovered, the filter frame 221 can be removed and the impurities on it cleaned for future use.

[0043] To ensure the stability of the filter frame 221 within the liquid storage chamber 212 and prevent problems such as loosening, detachment, or leakage between the frame strip 222 and the filter tank 215 due to hydraulic pressure or other factors, this embodiment features opposing ear plates 216 on both sides of the filter tank 215. Simultaneously, the frame strip 222 is also provided with fixing holes 223 corresponding to these ear plates 216. The frame strip 222 is then fixed to the ear plates 216 via pins 217, thereby further enhancing the stability and sealing of the filter frame 221.

[0044] refer to Figure 3 and Figure 4 In this embodiment, a slot 218 is provided on one side of the main body 21. The second filter assembly 23 includes a fixed frame 231, and a buckle 232 that engages with the slot 218 is provided on one side of the fixed frame. A filter plate 233 is detachably installed inside the fixed frame 231. During the quenching process, when the quenching liquid overflows into the overflow chamber 2112 and eventually flows into the cooling pool 1 through the outlet 214, the quenching liquid must first pass through the filter plate 233 located below the outlet 214. The filter plate 233 can intercept impurities in the quenching liquid, while the pure quenching liquid will pass smoothly through the filter plate 233 and flow into the cooling pool 1. After the quenching liquid is filtered, the impurities on the filter plate 233 need to be cleaned. Since the fixed frame 231 and the main body 21 are connected by the buckle 232 and the slot 218, the fixed frame 231 can be easily removed from the main body 21 for cleaning.

[0045] Example 2:

[0046] Based on the same inventive concept as Embodiment 1, refer to Figure 2 and Figure 5The quenching and cooling device for steel cord in this embodiment includes a cooling pool 1 for containing quenching fluid. A cooling platform 2 is provided on the top of the cooling pool 1. The cooling platform 2 includes a main body 21, and multiple cooling chambers 211 are provided on the top of the main body 21. Each pair of adjacent cooling chambers 211 is separated by a partition 219. Further, a liquid storage chamber 212 is provided inside the main body 21. Each cooling chamber 211 has an overflow port 213 at its bottom that communicates with the liquid storage chamber 212. Multiple discharge holes communicating with each cooling chamber 211 are provided on one side of the main body 21. A first filter assembly 22 is detachably installed inside the liquid storage chamber 212. The first filter assembly 22 is used to filter the quenching fluid discharged from the overflow port 213. A second filter assembly 23 is provided on the side of the main body 21 located below the discharge hole, and is used to filter the quenching fluid discharged from the discharge hole.

[0047] Furthermore, each cooling chamber 211 is movably equipped with an adjusting component 3. Specifically, the adjusting component 3 includes a baffle 31 disposed within the cooling chamber 211, which divides the cooling chamber 211 into a quenching chamber 2111 and an overflow chamber 2112. The overflow port 213 is located within the quenching chamber 2111, and the discharge hole is located within the overflow chamber 2112. A connecting sleeve 311 is provided on one side of the baffle 31 located within the overflow chamber 2112.

[0048] Furthermore, the adjusting assembly 3 also includes an adjusting screw 32 threadedly connected to the side wall of the main body 21. One end of the adjusting screw 32 is provided with a limiting block 321, which is movably connected to the connecting sleeve 311. The adjusting screw 32 is also provided with a fixing sleeve 322, which is located inside the overflow chamber 2112. The other end of the adjusting screw 32 passes through the side wall of the main body 21 and is connected to a handwheel 323, which is located at the end of the adjusting screw 32. By rotating the handwheel 323, the adjusting screw 32 can be moved axially, thereby driving the baffle 31 to move.

[0049] This device separates the quenching chamber 2111 from the overflow chamber 2112 via a baffle 31. The quenching chamber 2111 is the main area for quenching the steel cord. During operation, the adjusting screw 32 can be moved axially on the side wall of the main body 21 by rotating the handwheel 323. Since the adjusting screw 32 and the baffle 31 are movably connected by a connecting sleeve 311 and a limiting block 321, the movement of the adjusting screw 32 will cause the baffle 31 to move as well. The movement of the baffle 31 will change the length of the quenching chamber 2111, thereby adjusting the immersion length of the steel cord in the quenching liquid. The length of the quenching chamber 2111 can be flexibly adjusted according to different quenching requirements and the specifications of the steel cord to ensure that the steel cord achieves the best quenching effect during the quenching process.

[0050] Furthermore, the cooling pool 1 and the liquid storage chamber 212 are connected by a bidirectional pump, which is used to bidirectionally transport quenching liquid. The connection between the bidirectional pump and the liquid storage chamber 212 is located on one side of the bottom surface of the first filter component 22.

[0051] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
