Description

Technical Field

[0001] This utility model mainly relates to the field of tunnel furnace technology, and specifically to a cooling mechanism of a continuous quenching device. Background Technology

[0002] When the workpiece is continuously quenched and cooled using a tunnel furnace and an oil bath, the cooling oil in the oil bath needs to be cooled. In the current design of the oil bath, a chain conveyor line is installed inside, which causes the circulation of the cooling oil in the oil bath to be blocked by the structure of the chain conveyor line equipment, resulting in many dead water areas. The flow rate of the cooling oil in these areas is slow, resulting in a large temperature gradient difference in the oil bath.

[0003] The inventors proposed a cooling mechanism for a continuous quenching device. By setting inlet and outlet ports for cooling oil at opposite corners of the oil tank, making openings in the mounting structure of the chain conveyor line, and setting partition plates on the chain conveyor line, the mechanism increases the pushing effect of the chain conveyor line on the cooling oil during operation, improves the flow efficiency of the cooling oil in the oil tank, and reduces the occurrence of large temperature gradient differences in the cooling oil in the oil tank due to low fluidity.

[0018] 3. Beneficial effects:

[0019] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0020] This utility model provides a cooling mechanism for a continuous quenching device. The oil pump pumps the cooling oil in the oil tank to the oil circuit spiral sleeve through the oil inlet pipe. The cooling oil in the oil circuit spiral sleeve is then guided back to the oil tank through the oil return pipe. The oil outlet and oil inlet are set diagonally. Together with the chain plate and the partition plate, the cooling oil in the oil tank is pushed by the chain plate and the partition plate to improve the fluidity of the cooling oil in the oil tank and avoid a high temperature gradient due to poor fluidity of the cooling oil in the oil tank.

[0021] This utility model provides a cooling mechanism for a continuous quenching device.

[0043] See attached document Figure 1-8 This utility model provides a cooling mechanism for a continuous quenching device, comprising the following structure:

[0044] Oil tank 1, with a chain conveyor line from the front to the rear of the inner wall of oil tank 1, and an isolation frame 7 detachably snapped onto the front of the inner wall of oil tank 1, with a guide inclined plate 8 fixedly installed at the bottom rear side of the isolation frame 7.

[0045] Oil passage spiral sleeve 5, with water passage spiral sleeve 6 movably sleeved on the outer side of oil passage spiral sleeve 5.

[0046] In this embodiment, a cover 11 is fixedly provided at the top center of the oil tank 1, and a receiving rack 12 that is compatible with the discharge side of the quenching tunnel furnace is detachably snapped onto the front end of the oil tank 1.

[0047] The cover 11 is used in conjunction with the oil tank 1. The cover 11 shields the chain conveyor section structure that is immersed in the cooling oil in the oil tank 1. The receiving rack 12 receives the workpieces from the discharge side of the quenching tunnel furnace.

[0048] In this embodiment, the chain conveyor line includes a truss 2. The middle part of the truss 2 is inclined upward towards the top of the rear end of the oil tank 1. The rear end of the truss 2 extends upward to the outer side of the rear end of the oil tank 1. The left and right sides of the truss 2 are detachably connected to the left and right sides of the inner wall of the oil tank 1, respectively. A plurality of drainage holes 21 are fixed in the middle part of the truss 2. A drive motor 3 is fixed in the top of the rear end of the truss 2. A first sprocket 31 is fixed in the left output end of the drive motor 3.

[0049] The top left and right sides of the rear end of the truss 2 are movably connected to the left and right ends of the drive roller 22, respectively. The left end of the drive roller 22 is fixedly connected to the middle right end of the second sprocket 23. The outer side of the second sprocket 23 is connected to the outer side of the first sprocket 31 via chain drive. The bottom left and right sides of the front end of the truss 2 are movably connected to the left and right ends of the auxiliary roller 24, respectively. Multiple sets of idlers 25 are movably connected at the bend in the middle of the truss 2.

[0050] A chain plate line 4 is movably connected to the outer side of the drive roller 22. Multiple partition plates 41 are detachably snapped onto the outer side of the chain plate line 4 at equal intervals. The inner front end of the chain plate line 4 is movably connected to the outer side of the auxiliary roller 24. The left and right sides of the chain plate line 4 are movably connected to the outer side of the idler roller 25.

[0051] The drive motor 3 works in conjunction with the first sprocket 31 to drive the second sprocket 23 to rotate, thereby driving the drive drum 22 to drive the chain plate 4. The chain plate 4 transports the workpieces received at the receiving rack 12 into the cooling oil in the oil tank 1. The chain plate 4 works in conjunction with the partition plate 41 to drive the flow of cooling oil in the oil tank 1.

[0052] In this embodiment, docking sleeves 71 are fixedly provided at both the left and right ends of the isolation frame 7. The middle parts of the two docking sleeves 71 are movably connected to the left and right ends of the filter cylinder 72, respectively. The left end of the filter cylinder 72 is movably connected to the outside of the oil inlet end of the oil inlet pipe 52. A filter hole is fixedly provided in the middle of the filter cylinder 72. A filter sponge 73 is detachably snapped into the middle of the isolation frame 7. The bottom of the filter sponge 73 is laid on the top outside of the filter cylinder 72. The rear side of the filter sponge 73 faces the guide inclined plate 8. Scrapers 74 are fixedly provided at both the front and rear ends of the middle of the isolation frame 7. The opposite sides of the two scrapers 74 abut against the front and rear sides of the top of the filter cylinder 72, respectively.

[0053] The filter cylinder 72 is mounted on the isolation frame 7 via the docking sleeve 71. The oil inlet of the oil inlet pipe 52 extends to the middle of the filter cylinder 72. The cooling oil in the oil tank 1 is pushed by the chain plate 4 and the partition plate 41, passes through the guide inclined plate and the isolation frame 7, and after preliminary filtration by the filter sponge 73, the cooling oil enters the filter cylinder 72. The oil pump 51 and the oil inlet pipe 52 cooperate to transport the cooling oil to the oil circuit spiral sleeve 5. The cooling oil flowing in the oil circuit spiral sleeve 5 and the cold water circulating in the water circuit spiral sleeve 6 work together to complete the cooling treatment of the cooling oil in the oil tank 1.

[0054] The oil inlet pump 51 is turned on and off by a first temperature switch, and the water inlet pump 61 is turned on and off by a second temperature switch.

[0055] In this embodiment, the bottom of the guide ramp 8 extends to the middle of the inner wall bottom surface of the oil tank 1, and the top of the guide ramp 8 extends to the bottom of the chain conveyor line.

[0056] The push-flow effect of the chain plate 4 and the partition plate 41 improves the flow efficiency of the cooling oil in the oil tank 1. The impurities accumulated at the bottom of the inner wall of the oil tank 1 are pushed to the filter sponge 73 by the guide plate. The user needs to replace the filter sponge 73 in subsequent processing. Considering the increase in weight of the filter sponge 73 after being immersed in the cooling oil, the filter sponge 73 is placed between the isolation frame 7 and the filter cylinder 72. There is no need to add additional measures to fix the filter sponge 73. Moreover, the impurities in the oil tank 1 will accumulate in the filter sponge 73, further increasing the weight of the filter sponge 73. The overall structure design is reasonable and convenient to use.

[0057] In this embodiment, the middle input end of the oil circuit spiral sleeve 5 is fixedly connected to the output end of the oil inlet pump 51. The control end of the oil inlet pump 51 is electrically connected to a first temperature switch, which is detachably snapped into the inside of the oil sump 1. The input end of the oil inlet pump 51 is fixedly provided with an oil inlet pipe 52, and the output end of the oil circuit spiral sleeve 5 is fixedly provided with a return oil pipe 53. The oil outlet of the return oil pipe 53 and the oil inlet of the oil inlet pipe 52 are diagonally arranged about the oil sump 1, and the oil inlet of the oil inlet pipe 52 is close to the front of the oil sump 1, while the oil outlet of the return oil pipe 53 is close to the rear of the oil sump 1.

[0058] The oil pump 51 pumps the cooling oil in the oil tank 1 to the oil circuit spiral sleeve 5 through the oil inlet pipe 52. The cooling oil in the oil circuit spiral sleeve 5 is then guided back to the oil tank 1 through the return oil pipe 53. The oil outlet and oil inlet are set diagonally. Together with the chain plate line 4 and the partition plate 41, the cooling oil in the oil tank 1 is pushed by the chain plate line 4, which improves the fluidity of the cooling oil in the oil tank 1 and avoids a high temperature gradient due to poor fluidity of the cooling oil in the oil tank 1.

[0059] In this embodiment, the middle input end of the water spiral sleeve 6 is fixedly connected to the output end of the water inlet pump 61. The control end of the water inlet pump 61 is electrically connected to a second temperature switch, which is detachably snapped into the inside of the oil tank 1. The input end of the water inlet pump 61 is fixedly provided with an inlet pipe 62 that matches the water outlet end of the plant water system, and the output end of the water spiral sleeve 6 is fixedly provided with a return water pipe 63 that matches the water inlet end of the industrial chiller.

[0060] The industrial chiller provides cold water to the water circuit spiral sleeve 6. The water inlet pump 61 and the water inlet pipe 62 work together to provide cooling water to the water circuit spiral sleeve 6. The water circuit spiral sleeve 6 works with the oil circuit spiral sleeve 5 to complete the cooling treatment of the cooling oil in the oil tank 1. The water in the water circuit spiral sleeve 6 flows back to the industrial chiller through the return water pipe 63 for cooling treatment.

[0061] Based on the actual usage conditions and production situation on site, when production volume is low, a water storage tank can be built in conjunction with the water supply system of the factory area to supply water to the spiral water supply system instead of an industrial chiller. The cooling effect will be reduced, but the construction and use costs of the equipment can be significantly reduced.

[0062] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
