Description

Technical Field

[0001] This application relates to the field of heat transfer oil preparation equipment, specifically to a device for preparing high-temperature and oxidation-resistant heat transfer oil. Background Technology

[0002] Heat transfer oil, also known as thermal fluid, is a new type of energy-saving material. It has a high heat transfer coefficient and a high flash point, and does not decompose or volatilize at high temperatures, making it widely used for heating and cooling in industrial production processes. Due to its advantages such as high heat transfer efficiency, easy temperature control, non-corrosiveness to equipment, and low investment, heat transfer oil has been widely used in various industries including petrochemicals, papermaking, textiles, and aerospace.

[0003] Chinese patent document CN218249617U discloses a production device for high-performance heat transfer oil, including a base, a processing tank, and a mixing tank. The processing tank is bolted to the top of the base, and the top of the processing tank is connected to the mixing tank via a connecting pipe. A drive motor is bolted to one side of the mixing tank, and a limit port with a sealing plate is provided on one side of the connecting pipe. This novel high-performance heat transfer oil production device has a timing function and can pre-stir the raw materials.

[0004] However, the aforementioned patent does not include a filtration step for the heat transfer oil, which fails to remove impurities mixed into the processing tank or mixing box during the production process, thus affecting the quality of the heat transfer oil. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this application provides a device for preparing high-temperature resistant and oxidation-resistant heat transfer oil.

[0006] This application adopts the following technical solution: a high-temperature and oxidation-resistant heat transfer oil preparation device, including a filtration mechanism, the filtration mechanism including a shell, a movable plate and a fixed plate, the movable plate being located below the fixed plate and both being located inside the shell, the top of the shell being provided with a feed pipe, the bottom of the shell being provided with a discharge pipe, and the end of the discharge pipe passing through the top of the movable plate;

[0007] The fixed plate is a porous plate, the outer wall of the movable plate is attached to the inner wall of the shell, and the movable plate can slide up and down along the height direction of the shell.

[0008] Optionally, the housing is further provided with a hydraulic cylinder for driving the movable plate. The discharge pipe includes a pipe body, a connector and a first control valve. The connector is located on the movable plate. One end of the pipe body is sleeved on the connector, and the other end of the pipe body extends to the outside of the housing. The first control valve is located at the other end of the pipe body. The portion of the pipe body located inside the housing can extend and retract axially.

[0009] Optionally, the movable plate is made of rubber material, and the movable plate divides the interior of the housing into two non-communicating chambers.

[0010] Optionally, the housing is provided with a support ring, the top of which is attached to the top of the fixing plate, and the feed pipe is provided with a second control valve.

[0011] Optionally, the inner wall of the housing is provided with a receiving groove on one side and an opening on the other side. The bottom of the receiving groove is flush with the top of the fixing plate. A brush plate is provided in the receiving groove, and the bottom of the brush plate is provided with brush bristles.

[0012] The brush plate has a pair of support rods on the side facing the opening, and a door is provided on the outside of the opening that can be opened and closed. One end of the support rod is connected to the brush plate and the other end is connected to the door.

[0013] Optionally, the housing is square, and the bristles are used to brush the top of the fixing plate.

[0014] In summary, this application has the following beneficial effects:

[0015] 1. The movable plate is driven to move down by a hydraulic cylinder, forming a negative pressure zone above the movable plate. This promotes the heat transfer oil to pass through the mesh-like fixed plate, which accelerates the filtration process and improves the quality of the finished heat transfer oil.

[0016] 2. The movable plate is driven to move upward by the hydraulic cylinder, forming a positive pressure zone above the movable plate, thereby blowing impurities on the fixed plate upward. At the same time, the brush plate is pulled to brush the fixed plate, which effectively improves the cleaning effect of the fixed plate and ensures that the fixed plate can reliably filter the heat transfer oil.

[0020] The present application will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0021] like Figure 1-2 As shown, a high-temperature and oxidation-resistant heat transfer oil preparation device includes a filtration mechanism. The filtration mechanism includes a housing 1, a movable plate 2, and a fixed plate 3. The movable plate 2 is located below the fixed plate 3 and is located inside the housing 1. The top of the housing 1 is provided with a feed pipe 11, and the bottom of the housing 1 is provided with a discharge pipe 12. The end of the discharge pipe 12 passes through the top of the movable plate 2. The fixed plate 3 is a porous plate. The outer wall of the movable plate 2 is attached to the inner wall of the housing 1. The movable plate 2 can slide up and down along the height direction of the housing 1.

[0022] When the high-viscosity heat transfer oil is fed into the inner side of the housing 1 through the feed pipe 11, it will fall to the top of the fixed plate 3. At this time, the movable plate 2 moves downward, which can form a negative pressure above the movable plate 2, thereby promoting the heat transfer oil to pass through the fixed plate 3, and thus playing a filtering role for the heat transfer oil. The structure is compact and reliably removes impurities in the heat transfer oil, which can significantly improve the quality of the heat transfer oil.

[0023] The housing 1 is further equipped with a hydraulic cylinder 13, which drives the movable plate 2. The discharge pipe 12 includes a pipe body 121, a connector 122, and a first control valve 123. The connector 122 is mounted on the movable plate 2. One end of the pipe body 121 is fitted onto the connector 122, and the other end of the pipe body 121 extends to the outside of the housing 1. The first control valve 123 is located at the other end of the pipe body 121. The portion of the pipe body 121 located inside the housing 1 can extend and retract axially. The movable plate 2 is made of rubber material and divides the interior of the housing 1 into two non-communicating chambers. Thus, when the push rod of the hydraulic cylinder 13 extends, the movable plate 2 can move upward, thereby forming a positive pressure zone above the movable plate 2. When the push rod of the hydraulic cylinder 13 retracts, the movable plate 2 can move downward, thereby forming a negative pressure zone above the movable plate 2. Furthermore, since the tube 121 is extensible, it ensures that the tube 121 can reliably extend and retract without breaking during the movement of the movable plate 2.

[0024] The housing 1 is equipped with a support ring 14, the top of which fits against the top of the fixed plate 3. A second control valve 110 is provided on the feed pipe 11. The support ring 14 supports the fixed plate 3, ensuring that the relative interaction between the heat transfer oil and the fixed plate 3 does not cause the fixed plate 3 to move or be damaged during the process of accelerating the flow of heat transfer oil under negative pressure, thus ensuring the reliable heat transfer effect of the fixed plate 3 on the heat transfer oil.

[0025] The inner wall of the housing 1 has a receiving groove 15 on one side and an opening 16 on the other side. The bottom of the receiving groove 15 is flush with the top of the fixing plate 3. A brush plate 4 is provided in the receiving groove 15, and brush bristles 41 are provided at the bottom of the brush plate 4. A pair of support rods 42 are provided on the side of the brush plate 4 facing the opening 16. A door 5 is provided on the outside of the opening 16, which can be opened and closed. One end of the support rod 42 is connected to the brush plate 4, and the other end is connected to the door 5. The housing 1 is square, and the brush bristles 41 are used to brush the top of the fixing plate 3. During feeding, both the first control valve 123 and the second control valve 110 are in the open state. When the top of the fixing plate 3 is filled with heat transfer oil, the second control valve 110 closes, and the push rod of the hydraulic cylinder 13 moves downward. At this time, the heat transfer oil is drawn into the pipe 121 and discharged outward. When a significant amount of impurities accumulate on the fixed plate 3, the first control valve 123 and the second control valve 110 are closed. Then, the push rod of the hydraulic cylinder 13 moves upward, causing the movable plate 2 to move upward and simultaneously pulling the door 5 outward. This causes the brush plate 4 to move along the length of the support rod 42, thus creating a brushing action on the fixed plate 3 and removing impurities from it. Furthermore, the upward movement of the movable plate 2 enables a blowing action on the fixed plate 3, facilitating the direct removal of impurities from the fixed plate 3 and their discharge through the opening 16, effectively improving the cleaning efficiency and effectiveness of the fixed plate 3.

[0026] The above embodiments are merely preferred embodiments of this application and should not be construed as limiting the scope of protection of this application. Any non-substantial changes and substitutions made by those skilled in the art based on this application shall fall within the scope of protection claimed by this application.
