They can also bypass or purify the oil online as needed. The main components of vacuum oil purifiers include primary filters, vacuum evaporators, oil pumps, filter devices, condensers, and vacuum pumps. Vacuum oil purifiers need to be operated under certain temperature conditions. However, existing vacuum oil purifiers have problems with inadequate temperature management during operation, which can easily lead to equipment damage and reduce work efficiency. Summary of the invention

[0003] In view of this, the utility model aims to overcome the deficiencies of the above-mentioned problems in the prior art and proposes a temperature protection device for an oil purifier.

When the temperature is lower than the set temperature, the relay closes to heat the oil. When the temperature reaches a temperature higher than the set temperature, the relay releases and returns to the normally open state, and the heating is interrupted. When the temperature drops to the set temperature, the relay closes again.

[0008] Furthermore, the control device is also electrically connected to a power switch of the control cabinet.

[0009] Furthermore, the control device includes a main controller and an AD converter, an IO interface, a comparator, and an alarm electrically connected to the controller.

[0012] Furthermore, the first temperature control device and the second temperature control device are both connected to the main controller via an IO interface.

[0013] Furthermore, the main controller adopts a single chip microcomputer.

[0014] Furthermore, the alarm uses sound or light to give an alarm.

[0015] Furthermore, the AD converter uses the ICL7135 chip, and outputs the CLK and BUSY signals of the ICL7135 as AD conversion values.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0030] like Figure 1-3As shown, the utility model provides a temperature protection device for an oil purifier, comprising a heating thermostat 1 arranged on an oil inlet pipeline of the oil purifier, a first temperature detection device 2 arranged in an evaporation chamber of the oil purifier, a first temperature control device 3 arranged in the evaporation chamber of the oil purifier, a second temperature detection device 4 arranged in a control cabinet of the oil purifier, and a control device 5, wherein the heating thermostat 1, the first temperature detection device 2, the second temperature detection device 4, and the first temperature control device 3 are all electrically connected to the control device 5;

[0031] The heating thermostatic device 1 is used to heat the external oil before it enters the oil purifier for filtration. The first temperature detection device 2 is used to detect the temperature data inside the evaporation chamber of the oil purifier. The first temperature control device 3 is used to control the operation of the heater inside the evaporation chamber. The second temperature detection device 4 is used to detect the temperature data inside the control cabinet of the oil purifier.

[0032] Specifically, the heating constant temperature device 1 includes a heater, a second temperature control device, a third temperature detection device and a relay. The third temperature detection device sends the temperature of the oil to the second temperature control device. When the temperature is lower than the set temperature, the relay closes to heat the oil. When the temperature reaches a temperature higher than the set temperature, the relay releases and returns to the normally open state, and the heating is interrupted. When the temperature drops to the set temperature, the relay closes again.

[0033] Specifically, the control device 5 is also electrically connected to a power switch of the control cabinet.

[0034] Specifically, the control device 5 includes a main controller and an AD converter, an IO interface, a comparator, and an alarm electrically connected to the controller.

[0035] Specifically, the first temperature detection device 2 , the second temperature detection device 4 , and the third temperature detection device are all electrically connected to the main controller via an AD converter.

[0036] Specifically, the first temperature detection device 2, the second temperature detection device 4, and the third temperature detection device are all temperature sensors.

[0037] Specifically, the first temperature control device and the second temperature control device are both connected to the main controller via an IO interface. In the present utility model, the first temperature control device and the second temperature control device can both adopt a single chip microcomputer.

[0038] Specifically, the main controller adopts a single chip microcomputer.

[0039] Specifically, the alarm uses sound or light to give an alarm.

[0040] Specifically, the AD converter uses the ICL7135 chip, and the CLK and BUSY signals of the ICL7135 are output as AD conversion values.

[0041] When the utility model is working, a heating thermostatic device arranged on the oil inlet pipeline of the oil purifier is used to control the temperature of the oil entering the oil purifier in real time. After the oil is heated, it enters the oil purifier for filtration, which has a better filtering effect, improves the filtering accuracy, and further improves the purification efficiency.

[0042] The utility model also uses a temperature sensor arranged in the evaporation chamber of the oil purifier to detect the temperature data inside the evaporation chamber of the oil purifier, and sends it to the main controller. The main controller inputs the detected data into the comparator, and compares it with the threshold value set in the comparator. When the threshold value is exceeded, the heater in the evaporation chamber is controlled to stop working through the first temperature control device to avoid damage to the device caused by overheating.

[0043] As the power consumption of the equipment increases, the temperature generated by the control switch in the control cabinet of the oil purifier increases accordingly. Over time, the control switch is easily damaged and an electrical fire is easily caused. For this reason, the utility model also detects the internal temperature data of the oil purifier control cabinet through a temperature sensor and sends it to the main controller. The main controller inputs the detected data into the comparator and compares it with the threshold set in the comparator. When the set threshold is exceeded, the power switch in the control cabinet is controlled to stop working to reduce the occurrence of safety accidents.

[0044] In summary, the utility model realizes the temperature control and management of each link of the oil purifier during the working process, reduces the danger and improves the working efficiency.

[0045] All matters not mentioned above are prior art.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
