Description

Technical Field

[0001] This utility model relates to the field of industrial heating, and in particular to a dual-temperature-position heat transfer oil heating system. Background Technology

[0002] Dual-temperature thermal oil heating devices are widely used in various industrial applications requiring high-temperature heating and precise temperature control, such as petroleum, chemical, printing and dyeing, food, pharmaceutical, rubber, and plastics industries. In these industries, dual-temperature thermal oil heating devices can provide stable, efficient, and safe heating solutions to meet various complex heating needs.

[0003] Traditional filters are mostly installed using bolts. While this design ensures the stability of the filter to a certain extent, it brings many inconveniences in actual maintenance. When cleaning or replacing the filter, operators must first remove multiple bolts that fix the filter. This not only consumes a lot of time and effort, but also causes wear on the bolt holes and threads during frequent disassembly and assembly, increasing the difficulty and cost of equipment maintenance. In addition, cleaning debris from the inside of traditional filters is relatively troublesome. Due to the limited internal space of the filter, it is difficult for operators to completely clean all the debris, especially in some dead corners and hidden places of the filter. Long-term accumulation of debris can obstruct the flow of heat transfer oil, reduce heating efficiency, and even cause malfunctions.

[0004] Therefore, it is necessary to provide a new dual-temperature-position heat transfer oil heating system to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a dual-temperature-position heat transfer oil heating system.

[0006] The dual-temperature thermal oil heating system provided by this utility model includes: a heating box, an oil pipe, a fixed ring, a sliding pipe, a snap-fit ​​mechanism, a limiting rod, and a filter. A circulation pump is connected to one side of the heating box via a pipe. The oil inlet end of the oil pipe is connected to the circulation pump. A heat exchanger is installed in the middle of the oil pipe. The oil return end of the oil pipe is connected to the heating box. A fixed ring is installed on one end face of the oil pipe near the oil return end. A sliding pipe is installed inside the fixed ring. The end of the sliding pipe away from the fixed ring is fixedly connected to the other end face of the oil pipe near the oil return end. A snap-fit ​​mechanism is installed between the fixed ring and the sliding pipe to connect the fixed ring and the sliding pipe together. Limiting rods are symmetrically installed on one end of the oil pipe near the fixed ring. A filter is installed inside the sliding pipe.

The inside of each of the two ear plates is rotatably connected to a snap-fit. An arc-shaped groove is opened at one end of the sliding tube near the fixed ring. The inner wall of the arc-shaped groove snaps with one end of each of the two snap-fits.

[0008] Preferably, ear plates are fixedly connected to both sides of one end face of the oil pipe near the return oil end. Limiting holes are opened in the middle of the two ear plates. The other end of the two buckles is opened with through holes that match the limiting holes. The two limiting rods pass through the corresponding through holes and are inserted into the corresponding limiting holes.

[0009] Preferably, a first sealing ring is installed inside the fixed ring, and a second sealing ring is installed inside the sliding tube.

[0010] Preferably, a first filter screen is slidably connected to the middle of the filter, a second filter screen is fixedly connected to one end of the first filter screen, and the end of the second filter screen away from the first filter screen is slidably connected to the inner wall of the filter.

[0011] Preferably, the diameter of the filter pores of the first filter screen is larger than the diameter of the filter pores of the second filter screen.

[0012] Preferably, the filter has vertical rod 1 symmetrically slidably connected inside, and vertical rod 2 is fixedly connected to both sides of the second filter screen. A horizontal rod is fixedly connected between the two vertical rod 1 and the two vertical rod 2.

[0013] Compared with related technologies, the dual-temperature-position heat transfer oil heating system provided by this utility model has the following beneficial effects:

[0014] Easy installation and removal:

[0015] The design of the snap-fit ​​mechanism and the limiting rod makes the connection and disassembly between the sliding tube and the fixed ring very simple and quick. Operators can easily disassemble and reinstall the filter without using complicated tools or performing tedious steps. This convenient installation and disassembly process not only improves maintenance efficiency but also reduces the labor intensity of operators.

[0016] High-efficiency filtration and cleaning / maintenance:

[0017] The filter installed inside the sliding tube and its two-stage filter design (first filter and second filter) can efficiently intercept large particles and fine impurities in the heat transfer oil, significantly improving the cleanliness of the heat transfer oil. This design not only extends the service life of the heat transfer oil, but also reduces the failure rate of the system due to impurities clogging. The filter is easy to disassemble and clean, making it convenient for operators to perform regular maintenance and upkeep, ensuring the long-term stable operation of the system.

[0018] Good sealing performance:

[0019] The first and second sealing rings installed between the fixed ring and the sliding tube ensure the sealing of the heat transfer oil during circulation, preventing leakage and contamination.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] Please see Figures 1 to 5A dual-temperature thermal oil heating system includes: a heating box 1, an oil pipe 3, a fixing ring 5, a sliding pipe 6, a clamping mechanism 7, a limiting rod 8, and a filter 9. A circulating pump 2 is connected to one side of the heating box 1 via a pipe. The oil inlet end of the oil pipe 3 is connected to the circulating pump 2. A heat exchanger 4 is installed in the middle of the oil pipe 3. The oil return end of the oil pipe 3 is connected to the heating box 1. A fixing ring 5 is installed on one end face of the oil pipe 3 near the oil return end. A sliding pipe 6 is installed inside the fixing ring 5. The end of the sliding pipe 6 away from the fixing ring 5 is fixedly connected to the other end face of the oil pipe 3 near the oil return end. A clamping mechanism 7 is installed between the fixing ring 5 and the sliding pipe 6 to connect them together. Limiting rods 8 are symmetrically installed on one end of the oil pipe 3 near the fixing ring 5. The filter 9 is installed inside the moving pipe 6. The snap-fit ​​mechanism 7 includes a snap-fit ​​71 and an arc groove 72. Both sides of the fixed ring 5 are fixedly connected to ear plates 10. The snap-fit ​​71 is rotatably connected inside the two ear plates 10. The sliding pipe 6 has an arc groove 72 at one end near the fixed ring 5. The inner wall of the arc groove 72 snaps with one end of the two snap-fit ​​71. Both sides of the oil pipe 3 have ear plates 11 fixedly connected to one end face near the return oil end. Limiting holes 12 are opened in the middle of the two ear plates 11. The other end of the two snap-fit ​​71 has a through hole that matches the limiting hole 12. The two limiting rods 8 pass through the corresponding through holes and are inserted into the corresponding limiting holes 12. The fixed ring 5 has a first sealing ring 13 installed inside. The sliding pipe 6 has a second sealing ring 14 installed inside.

[0029] It should be noted that: the end of the buckle 71 near the ear plate 10 is eccentrically designed, and the eccentric block matches the inner wall of the arc groove 72 at one end of the fixing ring 5. Square grooves are opened on both sides of the fixing ring 5 at positions corresponding to the buckle 71, so that the buckle 71 can rotate freely. The first sealing ring 13 installed inside the fixing ring 5 is used for sealing between the sliding tube 6 and the fixing ring 5. The second sealing ring 14 installed inside the sliding tube 6 is used for sealing between the sliding tube 6 and the oil pipe 3.

[0030] Please see Figure 4 and Figure 5 A first filter screen 15 is slidably connected to the middle of the filter 9. A second filter screen 16 is fixedly connected to one end of the first filter screen 15. The end of the second filter screen 16 away from the first filter screen 15 is slidably connected to the inner wall of the filter 9. The filter hole diameter of the first filter screen 15 is larger than that of the second filter screen 16. Vertical rods 17 are symmetrically slidably connected inside the filter 9. Vertical rods 18 are fixedly connected to both sides of the second filter screen 16. A horizontal rod 19 is fixedly connected between the two vertical rods 17 and the two vertical rods 18.

[0031] It should be noted that: the filter 9 has symmetrically opened round holes inside, and the first vertical rod 17 is slidably connected to the inner wall of the round hole to prevent debris from entering the round hole and affecting its normal sliding. The second vertical rod 18 passes through the first filter screen 15 and is fixedly connected to the second filter screen 16. The ends of the two sets of first vertical rods 17 and second vertical rods 18 away from the second filter screen 16 are fixedly connected by a horizontal rod 19. When the operator pulls the horizontal rod 19, the second filter screen 16, the first filter screen 15 and the intercepted debris will be brought out together.

[0032] The working principle of the dual-temperature-position heat transfer oil heating system provided by this utility model is as follows:

[0033] Heating stage: The heat transfer oil is injected into the heating box 1 and heated by the built-in heating element to reach the required high temperature;

[0034] Driven by circulating pump 2: The heated heat transfer oil is sent into oil pipe 3 under the action of circulating pump 2 and begins to circulate;

[0035] Heat exchanger 4 heat exchange: The heat transfer oil flows in the oil pipe 3. When it passes through the heat exchanger 4, it exchanges heat with the medium that needs to be heated, transferring heat to the medium while its own temperature decreases.

[0036] Oil return and filtration: After heat exchange, the heat transfer oil continues to flow and enters the oil return stage. During the oil return process, the heat transfer oil first passes through the filter 9 inside the sliding tube 6.

[0037] The heat transfer oil first flows through the first filter screen 15. The filter screen 15 has a larger filter pore diameter, which is mainly used to intercept large particles and impurities in the heat transfer oil. After the heat transfer oil is initially filtered by the first filter screen 15, it continues to flow through the second filter screen 16, which is fixedly connected to the first filter screen 15. The filter screen 16 has a smaller filter pore diameter, which can further intercept small particles and fine impurities in the heat transfer oil, ensuring the cleanliness of the heat transfer oil. After being filtered by two-stage filter screens, the cleanliness of the heat transfer oil is significantly improved. Then it flows back to the heating box 1, ready for the next round of heating and circulation.

[0038] When it is necessary to disassemble and clean the filter 9, the operator should first stop the machine and close the valves at the oil inlet and return ends of the oil pipe 3 to ensure that the heat transfer oil will not continue to flow.

[0039] The operator pulls the limiting rod 8 out of the limiting hole 12 in the ear plate 2 11 to unlock the limiting of the buckle 71. Then, the operator rotates the two buckles 71 around the ear plates 10 on both sides of the fixing ring 5 to disengage them from the arc groove 72 at one end of the sliding tube 6 and unlock the locking mechanism 7. At this time, the operator can hold the sliding tube 6 and slide it away from the fixing ring 5. Continue to slide the sliding tube 6, and the filter 9 inside it will gradually be exposed until the filter 9 can be removed.

[0040] After removing the filter 9, the operator holds the horizontal bar 19 inside the filter 9 and pulls it outward. Both ends of the horizontal bar 19 are fixedly connected to the vertical bar 17 and the vertical bar 2 18. The vertical bar 17 is slidably connected to the inside of the filter 9, and the vertical bar 2 18 is fixedly connected to the second filter screen 16. Since the first filter screen 15 and the second filter screen 16 are fixedly connected, pulling the horizontal bar 19 will cause the second filter screen 16 and the first filter screen 15 to move together, removing the debris trapped inside. Then, the operator can clean the filter screen with a special cleaning agent.

[0041] After cleaning, the filter 9 needs to be reinstalled. The operator puts the filter 9 into the sliding tube 6 and slides the sliding tube 6 so that one end contacts the first sealing ring 13 inside the fixed ring 5, and the second sealing ring 14 at the other end contacts one end face of the oil return end of the oil pipe 3 to ensure a good seal.

[0042] Then, the operator rotates the buckle 71 to re-engage it into the arc groove 72 at one end of the sliding tube 6, completing the engagement. Finally, the limit rod 8 is inserted into the limit hole 12 to complete the limiting, ensuring that one end of the sliding tube 6 is securely connected to the fixing ring 5 and the other end is securely connected to the oil pipe 3, forming a sealed flow channel.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
