Description

Technical Field

[0001] The utility model relates to a laboratory water-cooled wall quenching oil tank capable of preventing moisture from entering the quenching oil, and belongs to the technical field of laboratory sample heat treatment equipment. Background Art

[0002] In steel enterprises, special steel has very high requirements for mechanical properties. Before the product leaves the factory, it is necessary to simulate the customer's heat treatment process for testing to verify whether it can meet the index requirements. The quenching oil used in heat treatment has strong quenching ability, but low flash point and is prone to fire. For steel exported to Europe or foreign-invested enterprises using European standards, the factory inspection of mechanical properties requires a section of steel to be heat treated as a whole, and a mechanical specimen is prepared at 12.5mm from the steel surface to inspect the performance index; due to the large volume of the steel overall heat treatment specimen, the oil temperature quickly rises to about 90°C during the quenching process, at which time the quenching ability decreases, and the liquid surface is extremely easy to burn. Water-cooled wall quenching tanks are generally used, and industrial circulating water is used for cooling to reduce the oil temperature. This kind of water-cooled wall quenching tank is easy to rust holes from the right-angle welds of the inner steel plate of the oil tank, allowing cooling water to enter the oil. Second, in summer, condensed water droplets are formed on the surface of the oil tank above the liquid level in the oil tank. The water droplets gradually become larger and flow into the oil under the action of gravity. The presence of water in quenching oil is a taboo in heat treatment. It will accelerate the aging and deterioration of the oil, change the cooling characteristics of the oil, cause uneven hardness, produce soft spots or soft hardness, and cause distortion of test results. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a laboratory water-cooled wall quenching oil tank which prevents moisture from entering the quenching oil. The water-cooled wall quenching oil tank can prevent cooling water from entering the quenching oil tank and prevent cooling water droplets from appearing on the inner wall of the quenching oil tank, thereby solving the problem of moisture entering the quenching oil in the laboratory water-cooled wall quenching oil tank.

[0004] The technical solution to solve the above technical problems is:

[0005] The invention discloses a laboratory water-cooled wall quenching oil tank for preventing moisture from entering the quenching oil. The water-cooled wall comprises a quenching oil tank and a water-cooled wall. The water-cooled wall is located outside the quenching oil tank and is four independent rectangular boxes. The four water-cooled walls are respectively connected to the four walls of the quenching oil tank. Each water-cooled wall is respectively composed of an inner wall, an outer wall and surrounding side walls. The inner wall is parallel to the outer wall and is opposite to each other. The surrounding side walls are respectively welded vertically to the surrounding edges of the inner wall and the outer wall. The areas of the inner wall and the outer wall of the water-cooled wall are smaller than the area of ​​the side wall of the quenching oil tank. The inner wall of the water-cooled wall is tightly connected to the outer surface of the side wall of the quenching oil tank. The surroundings of the inner wall of the water-cooled wall are respectively located inside the surrounding edges of the side wall of the quenching oil tank. The upper ends of the four water-cooled walls are respectively lower than the liquid level of the quenching oil in the quenching oil tank.

[0008] The beneficial effects of the utility model are:

[0009] The water-cooled wall of the utility model is composed of four independent water-cooled walls, the areas of the four water-cooled walls are smaller than the area of ​​the side walls of the quenching oil tank, the four water-cooled walls have no contact with the welds of the side walls of the quenching oil tank, even if the water-cooled wall leaks, the cooling water will not flow into the quenching oil through the welds of the quenching oil tank; the tops of the four water-cooled walls are below the quenching oil liquid level, thus avoiding the generation of condensed water drops on the inner surface of the side walls of the quenching oil tank, and preventing the condensed water from entering the quenching oil.

[0013] The utility model comprises a quenching oil tank 1, a water-cooled wall 2, a connecting water pipe 3, a cooling water inlet pipe 4, and a cooling water outlet pipe 5.

[0014] As shown in the figure, the water-cooled wall 2 is located outside the quenching oil tank 1. The water-cooled wall 2 is four independent rectangular boxes, and the four water-cooled walls 2 are respectively connected to the four walls of the quenching oil tank 1. One of the four water-cooled walls 2 is connected to the cooling water inlet pipe 4, and is sequentially connected to the other three water-cooled walls through the connecting water pipe 3, and the last water-cooled wall is connected to the cooling water outlet pipe 5. The cooling water enters the first water-cooled wall through the cooling water inlet pipe 4, and then enters the second water-cooled wall, the third water-cooled wall and the fourth water-cooled wall in sequence through the connecting water pipe 3. Finally, the cooling water flows out from the cooling water outlet pipe 5 of the fourth water-cooled wall to complete the cooling cycle.

[0015] As shown in the figure, each water-cooled wall 2 is composed of an inner wall 6, an outer wall 7, and surrounding side walls 8. The inner wall 6 is parallel to the outer wall 7, and the surrounding side walls 8 are vertically welded to the surrounding edges of the inner wall 6 and the outer wall 7. The area of ​​the inner wall 6 and the outer wall 7 of the water-cooled wall 2 is smaller than the inner side area of ​​the quenching oil tank 1. The inner wall 6 of the water-cooled wall 2 is tightly connected to the outer surface of the side wall of the quenching oil tank 1, and the surrounding of the inner wall 6 of the water-cooled wall 2 is located on the inner side of the surrounding edges of the side wall of the quenching oil tank 1. In this way, the water-cooled wall 2 avoids the weld of the side wall of the quenching oil tank 1. Even if the water-cooled wall 2 leaks due to weld corrosion, the cooling water will not flow into the quenching oil through the weld of the quenching oil tank 1, thereby eliminating the possibility of the cooling water of the water-cooled wall 2 entering the quenching oil in the quenching oil tank 1.

[0016] As shown in the figure, the upper ends of the four water-cooled walls 2 are respectively lower than the liquid level of the quenching oil in the quenching oil tank 1. With this design, the tops of the four water-cooled walls 2 are below the liquid level of the quenching oil, which avoids the formation of condensed water droplets on the inner surface of the side wall of the quenching oil tank 1, and no condensed water enters the quenching oil.

[0017] As shown in the figure, the three groups of connecting water pipes 3 between the four water-cooled walls 2 are bent pipes, and the three groups of bent pipes are respectively opposite to the three right angles of the quenching oil tank 1.

[0018] An embodiment of the present utility model is as follows:

[0019] The quenching oil tank 1 has a length of 1400 mm, a width of 950 mm, and a height of 1050 mm;

[0020] The length of water-cooled wall 2 is 1250 mm, the width is 720 mm, and the thickness is 70 mm;
