[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 3 As shown, an embodiment of the present invention provides a cooling device for heat transfer oil production, including a tank bottom 1, a tank body 11 and a tank cover 12. The tank bottom 1, the tank body 11 and the tank cover 12 are sealed and buckled to form a hollow inner cavity. An oil inlet pipe 13 and an oil outlet pipe 14 are provided on the tank body 11. The oil inlet pipe 13 and the oil outlet pipe 14 are respectively located on both sides of the tank body 11. The oil inlet pipe 13 is close to the tank bottom 1, and the oil outlet pipe 14 is close to the tank cover 12. A filter tank 2 is provided inside the tank body 11. The lower end of the filter tank 2 is connected to the oil inlet pipe 13, and the upper end of the filter tank 2 is connected to the oil outlet pipe 14. A filter assembly 23 is provided inside the filter tank 2, and a cooling water assembly 4 is provided inside the tank body 11 for cooling the heat transfer oil.

[0022] Furthermore, when the quenched heat transfer oil enters the oil inlet pipe 13, the heat transfer oil will directly pass through the oil inlet pipe 13 into the filter tank 2, and after filtering, it will be discharged from the oil outlet pipe 14. The water inlet pipe 15 on the tank cover 12 is connected to the cooling water assembly 4, and is arranged in a multi-stage cooling manner.

[0023] Specifically, a partition 21 is provided inside the filter tank 2, and a buffer chamber 22 is formed between the partition 21 and the lower portion of the filter tank 2. A filter assembly 23 is provided on the partition 21, and a cover 24 is fastened to the filter tank 2. The filter tank 2 and the cover 24 are sealed.

[0024] Specifically, a connecting seat 3 is provided on the partition 21, a through-hole area is formed in the middle of the connecting seat 3, a thread is formed on the outer side of the connecting seat 3, a sealing seat 32 is connected to the connecting seat 3 through a thread, a filter cartridge 34 is provided on the sealing seat 32, and dense small holes are formed on the filter cartridge 34 for filtering impurities in the thermal oil. A filter cover 35 is provided at the upper end of the filter cartridge 34, and a lifting ear 36 is provided at the upper end of the filter cover 35.

[0025] Furthermore, the quenched heat transfer oil enters the oil inlet pipe 13 and then directly enters the filter tank 2. First, the buffer chamber 22 in the filter tank 2 can effectively reduce the impact of the heat transfer oil and slow down the speed of the heat transfer oil. In addition, the oil inlet pipe 13 is at the bottom and the oil outlet pipe 14 is at the top, which also reduces the speed of the heat transfer oil, so that the heat transfer oil has more time to cool and filter during the flow.

[0026] It should be noted that the dense small holes on the filter cartridge 34 need to be designed according to the process of the thermal oil. Different thermal oil processes require filter cartridges 34 of different specifications, and the filter cartridge 34 is threadedly connected to the connecting seat 3 to facilitate disassembly and cleaning of the filter cartridge 34. The lifting ear 36 on the filter cover 35 is used to stably grasp the filter cover 35 for easy disassembly.

[0027] Specifically, a sealing ring 31 is sleeved on the connecting seat 3 , and a boss 33 is provided at the lower end of the sealing seat 32 . The boss 33 is provided corresponding to the sealing ring 31 .

[0028] Furthermore, by providing a sealing ring 31 on the connecting seat 3 and a boss 33 on the sealing seat 32, when the sealing platform and the connecting seat 3 are threadedly matched, the boss 33 can be tightly matched with the sealing ring 31, thereby achieving a three-level seal of thread matching, the sealing platform pressing the sealing ring 31, and the boss 33 fastening the sealing ring 31, thereby preventing the filtered heat transfer oil from mixing with the unfiltered heat transfer oil and reducing the filtering effect.

[0029] Specifically, a water inlet pipe 15 is provided on the tank cover 12, a drain pipe 16 is provided at the lower end of the tank bottom 1, and the cooling water assembly 4 is connected between the water inlet pipe 15 and the water outlet pipe. The cooling water assembly 4 includes a water distribution pipe 41, which is fixedly connected to the water inlet pipe 15. A nozzle 47 is provided at one end of the water distribution pipe 41, and a coil 42 is provided on the water distribution pipe 41. The coil 42 is located on the outside of the filter cartridge 34, one end of the coil 42 is connected to the water distribution pipe 41, and the other end of the coil 42 is fixedly connected to an annular pipe 44. A number of connecting pipes 45 are provided on the annular pipe 44, and the connecting pipes 45 pass through the partition 21. The lower end of the connecting pipe 45 is fixedly connected to a buffer ball pipe 46, and a spiral pipe 43 is fixedly connected to the water distribution pipe 41. The spiral pipe 43 is fixedly connected to the buffer ball pipe 46, and the buffer ball pipe 46 is fixedly connected to the drain pipe 16.

[0030] Furthermore, the cooling water assembly 4 is distributed on the outside of the filter tank 2, the outside of the filter cartridge 34, and the inside of the filter cartridge 34. The outside of the filter tank 2 is cooled by spraying with a nozzle 47. The nozzle 47 sprays the cooling water in the form of water droplets. The contact area between the cooling water and the hot air is large, so that the heat in the surrounding air is quickly transferred to the water droplets, thereby achieving rapid cooling. The spiral tube 43 and the coil 42 inside and outside the filter cartridge 34 are both spiral heat exchange tubes. The spiral shape can increase the length of the pipe inside and outside the filter cartridge 34, thereby increasing the direct contact area between the pipe and the thermal oil, thereby achieving the efficiency of heat exchange.

[0031] It should be noted that the buffer bulb 46 is used to buffer the cooling water in the connecting pipe 45 to prevent the cooling water in the connecting pipe 45 from falling directly from a high place into the lower part of the tank bottom 1, causing collision of the cooling water, affecting the device, and making a huge noise. A through hole is provided on the side of the buffer bulb 46 to release the cooling water after heat exchange, discharge the cooling water, reduce the impact of the cooling water, and a structure for connecting pipes is provided on both the filter cover 35 and the sealing cover 24.

[0032] Working principle: By setting a filter component 23 in the filter tank 2, when the quenched heat transfer oil enters the oil inlet pipe 13, the heat transfer oil will directly pass through the oil inlet pipe 13 into the buffer chamber 22 of the filter tank 2, and then upward into the filter cartridge 34, and flow out after being filtered through the holes on the filter cartridge 34, and finally discharged from the oil outlet pipe 14. Cooling water structures are provided on both sides of the filter cartridge 34 to cool the heat transfer oil to be filtered and the filtered oil to improve efficiency.

[0033] The above embodiments are only intended to help understand the method and core concept of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from the principles of the present invention, and such improvements and modifications also fall within the scope of protection of the claims of the present invention.
