[0038] In this embodiment, by moving the lever 102, the sliding block 111 slides on the surface of the lever 112 to compress the mounting spring-113, and the mounting block 110 slides until it is completely disengaged from the mounting hole 109. Then, the mounting plate 101 is removed and the filter plate 103 is taken out from the filter box 3, which facilitates the thorough cleaning and anti-clogging of the filter plate 103. When it is necessary to install the cleaned filter plate 103, the lever 102 is pulled first to slide the mounting block 110 to a suitable position, and then the filter plate 103 is placed into the filter box 3 through the mounting groove 107. Then the lever 102 is released, and the elastic force of the mounting spring-113 causes the sliding block 111 to slide and drive the mounting block 110 to slide into the mounting hole 109, ensuring the firm and stable engagement of the mounting plate 101 with the top of the filter box 3.

[0039] In a further preferred embodiment of the present invention, one end of the mounting block 110 and the interior of the mounting hole 109 form an engaging structure, and one end of the mounting block 110 and the upper end of one side of the sliding block 111 form a welded integrated structure.

[0044] In this embodiment, a serpentine heating tube 21 is used to increase its heating area and reduce the heating dead zone, which facilitates faster heating of the heat transfer oil entering the heating box 14.

[0045] The working principle of this utility model is as follows: First, the heat transfer oil return pipe 2 and heat transfer oil outlet pipe 5 are connected to external equipment. Then, they are connected to external cooling water delivery equipment through the cooling water inlet pipe 11 and cooling water outlet pipe 12. An external power supply is then connected. When the temperature sensor 6 detects a high temperature of the heat transfer oil inside the oil tank 4, the second pneumatic ball valve 18 is closed, and the first pneumatic ball valve 16 is opened. Then, the heat transfer oil pump 9 is started to deliver the heat transfer oil to the heat exchanger 13 through the circulating oil delivery pipe 20. Cooling water is then circulated through the cooling water inlet pipe 11 and cooling water outlet pipe 12 to cool the heat transfer oil. After cooling... The heat transfer oil flows back to the storage tank 4 through the circulation return pipe 15. The temperature of the heat transfer oil in the storage tank 4 is reduced by circulation cooling. Conversely, when the temperature of the heat transfer oil is detected to be high, the second pneumatic ball valve 18 is opened and the first pneumatic ball valve 16 is closed. Then, the heat transfer oil is transported to the heating box 14 through the circulation delivery pipe 20 and the connecting pipe 17 by the heat transfer oil pump 9. At this time, the heating pipe 21 is started to heat the heat transfer oil circulating into the heating box 14. The heated heat transfer oil is then transported to the storage tank 4 through the connecting pipe 17 and the circulation return pipe 15, so as to realize its automatic temperature regulation.

[0046] Simultaneously, the filter plate 103 filters the circulating heat transfer oil entering the filter box 3, removing large particles of impurities to prevent them from affecting the normal operation of the heat transfer oil pump 9, heat exchanger 13, or corresponding pipelines, or to prevent excessive impurities from affecting subsequent cooling or heating effects. The valve on the drain pipe 104 can be opened periodically to facilitate the discharge of impurities filtered by the filter plate 103, reducing the frequency of disassembly and cleaning of the filter plate 103. Furthermore, the pull rod 102 can be moved to drive the sliding block 111 to slide on the surface of the slide rod 112, compressing the mounting spring-113 and causing the mounting block 110 to slide completely out of the mounting hole 109. Afterwards, the mounting plate 101 can be removed to place the filter plate... 103 is removed from inside the filter box 3, which facilitates thorough cleaning and anti-clogging of the filter plate 103. When it is necessary to install the cleaned filter plate 103, the pull rod 102 can be pulled first to slide the mounting block 110 to the appropriate position. Then, the filter plate 103 is placed into the filter box 3 through the mounting groove 107. The sealing gasket 108 is used to improve the sealing performance after the lower end of the mounting plate 101 is engaged with the inside of the mounting groove 107 to prevent leakage of heat transfer oil. At the same time, the pull rod 102 is released, so that the elastic force of the mounting spring-113 causes the sliding block 111 to slide and drive the mounting block 110 to slide into the mounting hole 109, ensuring the firm and stable engagement of the mounting plate 101 with the top of the filter box 3.
