Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-stage air cooler technology, and in particular to a detachable multi-stage air cooler. Background Technology
[0002] In today's booming industrial production environment, various industrial processes have placed demands on the performance and adaptability of cooling equipment. In the petrochemical industry, from crude oil refining to the synthesis of various chemical products, a large amount of heat is released during the reaction process. High-efficiency cooling equipment must be used to regulate the temperature and ensure that the reaction proceeds stably. In the field of power generation, if the high heat generated by the continuous operation of generator sets cannot be dissipated in a timely and effective manner, it will not only reduce the power generation efficiency, but also cause equipment failure and affect the stability of power supply.
[0003] Traditional air coolers in the present technology are tightly connected by welding, and components such as fans are also installed in specific positions, making it difficult to make flexible adjustments. Under normal operating conditions, such traditional air coolers can complete the cooling task to a certain extent, provide basic cooling guarantee for industrial production, and maintain the basic operation of the production process.
[0004] In complex industrial production environments, system pressure is often unstable and prone to abnormal fluctuations. For example, when a pump suddenly stops working or when the pressure in the pipeline becomes unbalanced due to various unforeseen circumstances, the hot fluid loses its normal flow dynamics and is prone to backflow. At the same time, the strong impact force can damage the seals and cause fluid leakage, making the entire air cooler unable to operate normally. This reduces the stability and reliability of the air cooler and brings many potential risks and unnecessary economic losses to industrial production. Therefore, a detachable multi-stage air cooler is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a detachable multi-stage air cooler, which aims to improve the problem of backflow causing impact damage to the internal structure of the air cooler in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A detachable multi-stage air cooler includes a frame, a fan at the bottom of the frame, fins inside the frame, a check valve assembly on the side wall of the frame, and a detachment assembly at the top of the frame.
[0008] The check valve assembly includes a housing, the outer wall of which is disposed on the side wall of the frame. A conical block is disposed inside the housing. A locking post is fixedly connected to one end of the conical block. A spring is sleeved on the outer wall of the locking post. One end of the spring is fixedly connected to one side wall of the conical block. A limiting ring is fixedly connected to the other end of the spring. A sliding post is fixedly connected to one side wall of the conical block. A circular hole is opened inside the sliding post. The outer wall of the sliding post is slidably connected to the inner wall of the housing. The outer wall of the limiting ring is fixedly connected to the inner wall of the housing.
[0009] As a further description of the above technical solution:
[0010] The disassembly assembly includes a second outer shell, the bottom of which is disposed on the top of the fin, and a second sliding column is threadedly connected to the inner wall of the second outer shell.
[0011] As a further description of the above technical solution:
[0012] A knob is fixedly connected to the top of the second sliding column, and a cone-shaped block is fixedly connected to the bottom of the second sliding column.
[0013] As a further description of the above technical solution:
[0014] The inner wall of the outer shell 2 is provided with a sliding groove 1, the outer wall of the conical block 2 is slidably connected to the inner wall of the sliding groove 1, and a sliding column 3 is slidably connected inside the outer shell 2.
[0015] As a further description of the above technical solution:
[0016] The conical block 2 is externally slidably connected to the three side walls of the sliding column, and the three side walls of the sliding column are fixedly connected to the locking post 2.
[0017] As a further description of the above technical solution:
[0018] The outer casing 2 is provided with a limiting ring 2 inside, and a spring 2 is sleeved on the outer wall of the locking post 2. One end of the spring 2 is fixedly connected to the side wall of the limiting ring 2, and the other end of the spring 2 is provided at one end of the sliding post 3.
[0019] As a further description of the above technical solution:
[0020] The outer wall of the limiting ring is fixedly connected to the inner wall of the outer shell, and the outer wall of the locking post is slidably connected to the inner wall of the fin.
[0021] This utility model has the following beneficial effects:
[0022] In this invention, when the liquid flows from top to bottom, its pressure pushes the conical block to slide inside the outer shell, which then moves the sliding column, thereby compressing the spring and causing the conical block to leave the valve port, allowing the liquid to pass through. This achieves the effect of automatically opening the valve port under the action of liquid pressure, allowing the liquid to pass through smoothly, avoiding the problem of backflow causing impact damage to the internal structure of the air cooler, and improving the stability and reliability of the air cooler operation.
[0023] In this invention, by rotating the knob, the sliding column two is rotated. Since one side of the sliding column three is inclined, the conical block two moves upward along the inclined surface, which in turn moves the sliding column three. This causes the spring two to retract, allowing the locking column two to slide inside the outer shell two. This achieves the effect of convenient fin disassembly, solving the problem that fins are prone to clogging or damage and require quick disassembly for cleaning or replacement, thus improving work efficiency.

Detailed Implementation
[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1 and Figure 2The present invention provides an embodiment of a detachable multi-stage air cooler, comprising a frame 1, a fan 2 at the bottom of the frame 1, fins 3 inside the frame 1, which are installed on the frame 1 through a manufacturing process to increase the heat exchange area, a check valve assembly on the side wall of the frame 1 to prevent backflow of the medium, and a disassembly assembly on the side wall of the frame 1 to facilitate the maintenance and replacement of the fins 3.
[0031] The check valve assembly includes a housing 4, the outer wall of which is welded to the side wall of the frame 1. Inside the housing 4 is a conical block 6 with a smooth surface, allowing it to slide smoothly within the housing 4. One end of the conical block 6 is fixedly connected to a locking post 8, which is also made of alloy steel and is welded to the conical block 6 to ensure a strong connection. Inside the frame 1 is a limiting ring 10. A spring 9 is fitted onto the outer wall of the locking post 8, with one end fixedly connected to the side wall of the conical block 6 and the other end fixedly connected to the side wall of the limiting ring 10. The limiting ring 10 is made of stainless steel, and its outer wall is welded to the inner wall of the housing 4 to ensure that the spring 9 will not shift during operation. A sliding post 7 is fixedly connected to the side wall of the conical block 6, with a circular hole 19 inside. The outer wall of the sliding post 7 is slidably connected to the inner wall of the housing 4.
[0032] Specifically, during the orderly operation of the air cooler, as the liquid flows from top to bottom, it pushes the conical block 6, causing it to slide smoothly within the outer casing 4. This, in turn, causes the connected sliding column 7 to move synchronously. The displacement of the sliding column 7 further compresses and deforms the spring 9, causing the conical block 6 to move away from the valve port. The previously closed valve port then opens, allowing the liquid to pass through and supply the crucial cooling medium for the air cooler's heat exchange process. Once the liquid supply stops, the spring 9 quickly retracts, causing the sliding column 7 to slide in the opposite direction, thus precisely resetting the conical block 6 and blocking the valve port. This effectively prevents backflow of the medium, avoiding damage to the internal structure of the air cooler with its powerful impact, ensuring the safe and stable operation of the air cooler, and enabling it to continuously and reliably provide cooling services for industrial production and other processes.
[0033] Reference Figure 1 and Figure 3The disassembly assembly includes a second outer shell 5, made of engineering plastic, which can withstand certain external impacts and is lightweight and corrosion-resistant, effectively extending its service life. The bottom of the second outer shell 5 is located on top of the fin 3. A sliding column 11 is threadedly connected to the inner wall of the second outer shell 5, allowing for smooth up-and-down movement during rotation. A knob 12 is fixedly connected to the top of the sliding column 11, with a textured surface for easy gripping and torque application, providing a comfortable and stable feel during rotation. A conical block 13, made of aluminum alloy, is fixedly connected to the bottom of the sliding column 11, making it lightweight and wear-resistant. A groove 14 is formed on the inner wall of the second outer shell 5, fitting tightly against the outer wall of the sliding column 11. The design ensures the stability of the sliding column 11 during sliding and effectively guides its movement trajectory. A sliding column 15 is slidably connected inside the outer shell 5. The outer wall of the conical block 13 is slidably connected to the side wall of the sliding column 15. A locking column 17 is fixedly connected to the side wall of the sliding column 15 using a welding process. A limiting ring 18 is provided inside the outer shell 5. A spring 16 is sleeved on the outer wall of the locking column 17. One end of the spring 16 is fixedly connected to the side wall of the limiting ring 18, and the other end of the spring 16 is located at one end of the sliding column 15 and fixed to the inner wall of the outer shell 5 by welding, ensuring that the spring 16 maintains a stable position and elastic force during operation. The outer wall of the locking column 17 is slidably connected to the inner wall of the fin 3.
[0034] Specifically, after long-term use, the fins 3 of the air cooler are prone to blockage. When this occurs, rotating knob 12 causes sliding column 2 11 to rotate synchronously. Since the contact surface of sliding column 3 15 is inclined, under the action of sliding column 2 11, conical block 2 13 moves upward along the inclined surface, and sliding column 3 15 moves accordingly, causing spring 2 16 to retract and locking column 2 17 to slide within outer shell 2 5, facilitating the easy disassembly of fins 3. When cleaning is complete and it's time to replace fins 3, rotating knob 12 again causes sliding column 2 11 to move, sliding within slide groove 1 14. Based on the inclined structure of sliding column 3 15, conical block 2 13 moves downward along the inclined surface, compressing spring 2 16, and locking column 2 17 slides again within outer shell 2 5, completing the assembly of fins 3. This improves the overall heat exchange efficiency of the air cooler, ensures good cooling performance, helps the equipment maintain its optimal operating temperature range, and significantly improves the stability and reliability of the equipment.
[0035] Working principle: When the liquid flows from top to bottom, the pressure of the liquid drives the conical block 6 to move, which then slides inside the outer shell 4, causing the sliding column 7 to move. This, in turn, compresses the spring 9, causing the conical block 6 to move away from the valve port, thus opening the valve port and allowing the liquid to pass through and flow out from the round hole 19. When the liquid supply stops, the spring 9 retracts, causing the sliding column 7 to slide inside the outer shell 4, which in turn causes the conical block 6 to block the valve port, effectively preventing backflow of the medium and avoiding impact damage to the internal structure of the air cooler, such as deformation of the tube cavity or damage to the seals. This ensures the safe and stable operation of the air cooler.
[0036] Prolonged use of the air cooler can cause fins 3 to become clogged. In this case, rotating knob 12 causes sliding column 11 to rotate. Since the contact surface of sliding column 15 is inclined, it causes conical block 13 to move upwards along the inclined surface, simultaneously moving sliding column 15. This causes spring 16 to retract, allowing locking column 17 to slide inside outer shell 5, thus disassembling fins 3. When cleaning is complete and new fins 3 are needed, rotating knob 12 again causes sliding column 11 to move, sliding within groove 14. Again, the inclined contact surface of sliding column 15 causes conical block 13 to move downwards along the inclined surface, simultaneously compressing spring 16, allowing locking column 17 to slide inside outer shell 5, thus assembling fins 3. This improves the overall heat exchange efficiency of the air cooler, ensures its cooling effect, helps maintain the equipment within its optimal operating temperature range, and enhances the stability and reliability of the equipment.
[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
