[0024] The specific implementation of the present application will be described in detail below in combination with the drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present application, and is not used to limit the present application.

[0025] In the utility model, in not making opposite declaration case, the orientation word of "top, bottom, inside, outside" etc. Contained in the term only represents the orientation of the term in the normal use state, or is the common name of the understanding of the person skilled in the art, and should not be regarded as the restriction of the term.

[0026] Referring to Figure 1 The utility model provides a kind of bar sample heat treatment quenching oil tank, which comprises oil tank body 1, heating plate 2 and cooling oil tank 3, heating plate 2 is tightly arranged on the bottom end surface of oil tank body 1, cooling oil pump 4 is arranged in cooling oil tank 3, cooling oil pump 4 is connected with cooling oil pipe 5, cooling oil pipe 5 extends into oil tank body 1, and oil tank body 1 is connected with cooling oil tank 3 through reflux pipe 6.

[0027] Through the above technical scheme, in winter, a heating plate 2 is added at the bottom of the oil tank body 1 to increase the oil temperature in the oil tank body 1. Meanwhile, according to the amount of heat treatment samples, a cooling oil tank 3 is made on one side of the oil tank body 1 and connected with the oil tank body 1. When the oil temperature is high in summer, the oil pump is started, and a large amount of quenching oil is circulated and cooled to adjust the oil temperature in the oil tank body 1.

[0028] In the embodiment, in order to realize intelligent temperature sensing and intelligent temperature adjustment in cold environment, preferably, the bar sample heat treatment quenching oil tank further comprises a temperature controller 7 connected with the heating plate 2, and a thermometer 8 connected with the temperature controller 7 and extending into the oil tank body 1, and the temperature controller 7 is arranged to start or stop the heating plate 2 according to the temperature in the oil tank body 1. In this way, when the thermometer measures that the oil temperature in the oil tank body 1 is low and does not meet the requirements of bar sample heat treatment, the situation is fed back to the temperature controller 7, and the heating plate 2 is started by the temperature controller 7 to heat the oil tank body 1, so that the oil temperature in the oil tank body 1 gradually increases until it meets the requirements of bar sample heat treatment.

[0029] Similarly, in order to enable the bar sample heat treatment quenching oil tank to intelligently sense and adjust the temperature in high temperature, preferably, the temperature controller 7 is also connected with the cooling oil pump 4 and arranged to start or stop the cooling oil pump 4 according to the temperature in the oil tank body 1. In this way, when the thermometer measures that the oil temperature in the oil tank body 1 is high and does not meet the requirements of bar sample heat treatment, the situation is fed back to the temperature controller 7, and the cooling oil pump 4 is started by the temperature controller 7, and the cooling oil pump 4 adds the low-temperature oil in the cooling oil tank 3 to the oil tank body 1 through the cooling oil pipe 5, so that the low-temperature oil mixes with the original high-temperature oil in the oil tank body 1 to reduce the oil temperature in the oil tank body 1. In this process, due to the existence of the reflux pipe 6, a cooling oil circulation is formed between the oil tank body 1 and the cooling oil tank 3, which can continuously reduce the temperature until it meets the requirements of bar sample heat treatment.

[0030] In the temperature control process, in order to enable the thermometer 8 to accurately measure the oil temperature in the oil tank body 1, preferably, the thermometer 8 extends from the top to the bottom in the oil tank body 1.

[0031] In the circulating process of the cooling oil, in order to realize the overall circulation of the oil in the oil tank body 1 and the cooling oil tank 3, avoid the high-temperature oil or low-temperature oil concentrated in a certain area without participating in the circulation, and cause the low cooling efficiency and the unclear cooling effect, preferably, the backflow pipe 6 is connected at the bottom of the oil tank body 1 and the cooling oil tank 3. In this way, the oil at the bottom of the oil tank body 1 and the cooling oil tank 3 can smoothly participate in the circulation, accelerate the heat exchange, and greatly improve the cooling effect.

[0032] At the same time, when the cooling oil is circulating, if the pump oil speed of the cooling oil pump 4 is too fast, a large amount of cooling oil added into the oil tank body 1 cannot be timely returned to the cooling oil tank 3 through the backflow pipe 6, causing the oil level in the oil tank body 1 to rapidly rise, even overflow from the oil tank body 1, not only losing the temperature regulating effect, but also causing the waste of raw materials. In order to avoid this situation, preferably, the overflow pipe 9 is further connected between the top of the oil tank body 1 and the cooling oil tank 3. After the overflow pipe 9 is used, when the oil level in the oil tank body 1 rapidly rises, it will quickly return to the cooling oil tank 3 along the overflow pipe 9, avoiding the overflow phenomenon caused by the continuous rising of the liquid level.

[0033] In the embodiment, in order to enable the heating plate 2 to efficiently and uniformly heat the oil tank body 1 located above it, and enable the oil in the oil tank body 1 to be heated at a stable speed, preferably, the heating surface area of the heating plate 2 is greater than or equal to the bottom surface area of the oil tank body 1. In this way, the heating plate 2 can heat the entire bottom surface of the oil tank body 1 at the same time, and the heating effect is greatly improved.

[0034] Similarly, in order to enable the cooling oil to efficiently and uniformly cool the high-temperature oil in the oil tank body 1, preferably, the cooling oil pipe 5 is provided with multiple pipes, and the ends of the pipes respectively extend to multiple corners of the oil tank body 1 in the circumferential direction. In this way, the cooling oil in the cooling oil tank 3 is simultaneously added to the multiple corners of the oil tank body 1 through the multiple cooling oil pipes 5 by the cooling oil pump 4, realizing the efficient mixing of the cooling oil and the high-temperature oil.

[0035] Further, in order to enable the thermometer 8 to comprehensively measure the oil temperature in the oil tank body 1, and accurately measure the temperature, preferably, the thermometer 8 is provided with multiple pipes and symmetrically arranged in the oil tank body 1.

[0036] In the use of the bar sample heat treatment quenching oil tank, in order to make the operator can intuitively understand the oil temperature in the oil tank body 1 and the opening and closing state of various equipment, preferably, the temperature controller 7 is also connected with a display, which is used to display the temperature in the oil tank body 1 and the opening and closing state of the heating plate 2 and the cooling oil pump 4 in real time.

[0037] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the specific details in the above-described embodiments, and various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0038] In addition, it should be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present application will not further describe various possible combination manners.

[0039] In addition, various different embodiments of the present application can also be combined in any manner, as long as they do not deviate from the technical concept of the present application, and they should also be considered as disclosed by the present application.
