[0024] Working principle:

[0025] In use, the cleaning liquid is injected into the box 1 through the feeding hopper 4. After the equipment is started, the control box 2 supplies power to the electric heating wire 8 through the power line, and the electric heating wire 8 starts to heat. The heat generated by the electric heating wire 8 is transferred to the cleaning liquid in the heat preservation assembly 7, so that the temperature of the cleaning liquid is increased. The temperature of the cleaning liquid in the box 1 is monitored in real time by the temperature measuring instrument 5, and the temperature signal is transmitted to the control box 2. The controller in the control box 2 adjusts the heating power of the electric heating wire 8 according to the preset temperature range. When the temperature of the cleaning liquid is lower than the preset lower limit temperature, the control box 2 increases the power supply power of the electric heating wire 8 to accelerate the heating; when the temperature of the cleaning liquid reaches or exceeds the preset upper limit temperature, the control box 2 reduces the power supply power or stops the power supply, so as to realize the accurate control of the temperature of the cleaning liquid, so as to achieve the effect of compensation heating, and ensure that the temperature of the cleaning liquid is always in the appropriate fine grinding process temperature range. The supporting leg 3 can stably support the box 1.

[0026] In addition, the operator can set the timing heating time through the control box 2. When the set time is reached, the control box 2 automatically starts the electric heating wire 8 to heat, so as to realize the timing heating function; at the same time, the pre-booking heating time can also be set, and the control box 2 will start heating when the pre-booking time is reached, so as to meet the demand of pre-booking heating.

[0027] When it is necessary to heat the cleaning liquid in the heat preservation shell 71, the eighty-degree constant temperature liquid is injected into the spiral pipe 12 to circulate under the drive of the external power source. When the heat of the constant temperature fluid is transferred to the pipe wall of the spiral pipe 12, it can be quickly conducted to the heat conduction plate 72 in the heat preservation assembly 7. The heat dissipation ring 73 fixed outside the heat conduction plate 72 further enhances the heat dissipation effect. The heat dissipation ring 73 can more effectively transfer the heat from the heat conduction plate 72 to the cleaning liquid in the heat preservation shell 71. When the cleaning liquid circulates in the heat preservation shell 71 and contacts the heat dissipation ring 73, the heat is transferred from the heat dissipation ring 73 to the cleaning liquid, and at the same time, the driving motor 6 is started, and the output end drives the rotating shaft 74 to rotate, and the stirring paddle 75 fixed outside the rotating shaft 74 rotates. The stirring paddle 75 produces stirring effect on the cleaning liquid in the box 1 in the rotating process, so as to improve the heat absorption efficiency of the cleaning liquid and further enhance the heat preservation effect.

[0028] When the cleaning liquid is needed, the valve 10 on the discharge pipe 9 is opened, and the cleaning liquid flows out of the discharge pipe 9. The thermometer 11 is installed on the side of the discharge pipe 9 close to the valve 10, and the thermometer 11 monitors the temperature of the cleaning liquid in real time. The operator can observe the reading of the thermometer 11 to know the actual temperature of the discharged cleaning liquid.
