Description

Controllable oil temperature machine of heating efficiency Technical Field The invention relates to the technical field of temperature control of oil temperature machines, in particular to an oil temperature machine with controllable heating efficiency. Background The oil temperature machine is a mold temperature machine taking heat conducting oil as a medium, and can also be called as an oil heater, an oil temperature heater and an oil circulation temperature controller, wherein the oil temperature machine is provided with an oil storage tank by taking the heat conducting oil as a heat transfer medium as the name of the oil temperature machine, the heat conducting oil enters the system from the oil storage tank during operation and is pumped into a mold or other equipment needing temperature control through a circulating pump, the heat conducting oil returns to the system after coming out of the temperature controller, the heat conducting oil is heated through the heater repeatedly, when the temperature of the medium detected by a temperature sensing probe reaches a set value, the heater stops working, when the temperature is lower than the set value, the heater starts working, and after the temperature reaches the set value, the heater stops working, and the operation is circulated and reciprocated. The oil temperature machine in the current market has higher precision in temperature control aspect, can reach + -1 temperature control, has the advantages of stable heating, excellent heat preservation and heating effect and the like, and is widely applied to industries with higher requirements on Wen Pin (temperature quality: temperature control precision, heat stability, heating efficiency and the like) such as plastics, rubber products, metal materials, chemical industry and the like. The high temperature control precision, the heat stability and the high heating efficiency of the oil temperature machine are remarkable advantages from the high quality requirement of the heated carrier on the temperature, but the high heat stability is not only an advantage but also a disadvantage for the heated body which is cooperatively matched with the oil temperature machine such as a heating die, a reaction kettle and the like, because the heated body such as the heating die, the reaction kettle and the like generally does not need to be heated after the die forming and the reaction are finished, cooling is needed to accelerate the die forming and the smooth reaction, and when the heating is finished, although the oil temperature machine stops continuously heating and pumping the heat conduction oil, the heat conduction oil still carries higher heat in an oil outlet pipeline and an oil return pipeline due to the good heat stability of the heat conduction oil under the high temperature condition, which is equivalent to the fact that the heated body such as the heating die, the reaction kettle and the like is wrapped with a layer of heat preservation layer, the cooling time of the heated body is increased, and the machine with the high heat stability is slightly insufficient in practical application, and reasonable adjustment and improvement are needed to realize more sensitive cooperative matching according to the change of the requirement of the heated body. Aiming at the problems, innovative design is urgently needed on the basis of the original oil temperature machine with controllable heating efficiency. Disclosure of Invention The technical scheme of the invention aims at solving the technical problem that the prior art is too single, and provides a solution which is obviously different from the prior art, and particularly the invention aims to provide the oil temperature machine with controllable heating efficiency, so as to solve the problems that the prior art provides a heat receiving body which is matched with the oil temperature machine in a cooperative way for heating a die, a reaction kettle and the like, and has high heat stability, and the heat receiving body is not required to be heated after the die forming and the reaction are finished, but is required to be cooled down to accelerate the die forming and the reaction to be smooth, and the oil temperature machine stops continuously heating and pumping the heat conducting oil when the heating is finished, and the heat conducting oil stopped to pump still carries higher heat in an oil outlet pipeline and an oil return pipeline due to the fact that the heat conducting oil is still positioned in the oil outlet pipeline and the oil return pipeline, which are equivalent to the problem that the heat receiving body is wrapped with a layer of heat preservation layer outside the heating die, the reaction kettle and the like, and the cooling time of the heat receiving body is increased. The oil temperature machine with the controllable heating efficiency comprises an oil temperature machine body, an oil outlet tank, an oil return tank, a first sealing disc and a
