Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of closed cooling towers, and in particular relates to an air inlet regulating device for a circulating cooling mixed-flow closed cooling tower. Background Technology
[0002] Closed-circuit cooling towers place tubular heat exchangers inside the tower, ensuring cooling through heat exchange between circulating air, external spray water, and internal circulating water. Because the circulating water operates in a closed loop, it prevents water contamination, effectively protecting the main equipment and extending its lifespan. When the outside temperature is low, the spray water system can be shut off, saving water. In recent years, closed-circuit cooling towers have been widely used in industries such as steel metallurgy, power electronics, machining, and air conditioning systems.
[0003] Since the air intake direction of a conventional closed-circuit cooling tower is fixed, changing the air intake direction requires rotating the entire closed-circuit cooling tower. However, closed-circuit cooling towers are relatively bulky and difficult to operate, which makes adjusting the air intake direction of a conventional closed-circuit cooling tower quite troublesome.
[0004] To address these issues, we propose a circulating cooling mixed-flow closed-loop cooling tower air inlet regulating device. Utility Model Content
[0005] The purpose of this invention is to solve the problem of the cumbersome process of adjusting the air intake direction in conventional closed-circuit cooling towers, and to propose an air intake adjustment device for circulating cooling mixed-flow closed-circuit cooling towers.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A circulating cooling mixed-flow closed-loop cooling tower air intake regulating device includes a circulating cooling mixed-flow closed-loop cooling tower body. An air intake hood is fixedly connected to the lower air intake port of the circulating cooling mixed-flow closed-loop cooling tower body. An air-blocking cover is rotatably installed on the upper rear end of the air intake hood. A magnet is fixedly connected to the rear of the circulating cooling mixed-flow closed-loop cooling tower body, and the magnet is magnetically matched with the air-blocking cover. A spring-loaded buckle is fixedly connected to the lower part of the air intake hood, and the spring-loaded buckle is engaged with the air-blocking cover. Closing the air-blocking cover downwards reduces the air intake port at the rear of the air intake hood, causing the suction force of the side air intake port of the circulating cooling mixed-flow closed-loop cooling tower body to act on the air intake hood, allowing the air intake hood to draw in some gas from the front. Opening the air-blocking cover then restores the rear air intake state, facilitating adjustment of the air intake direction of the circulating cooling mixed-flow closed-loop cooling tower body.
[0008] Preferably, the suction hood includes a hood body and a rotating shaft sleeve. The inner end of the hood body is fixedly connected to the lower part of the circulating cooling mixed-flow closed-loop cooling tower body, and the rear part of the hood body is located at the air intake of the circulating cooling mixed-flow closed-loop cooling tower body. The rotating shaft sleeve is fixedly connected to the upper part of the hood body. The rotating shaft sleeve guides the air-blocking cover to flip down. After the air-blocking cover is flipped downwards, it blocks the air at the rear of the hood body, facilitating the transfer of some of the suction force inside the suction hood to the front.
[0009] Preferably, the air-blocking cover includes a baffle and a rotating shaft. The baffle is symmetrically fixedly connected to the rotating shaft, and the rotating shaft is rotatably mounted on a rotating shaft sleeve. The baffle is magnetically attracted to a magnet and is also fitted to the cover. Flipping the baffle downwards blocks the side opening of the cover, and vice versa, fully opens the rear opening of the cover, facilitating control of the air intake.
[0010] Preferably, the air-blocking cover further includes a reinforcing rod, which is fixedly connected between the two baffles and is matched with a spring-loaded buckle. The reinforcing rod increases the stability between the two baffles.
[0011] Preferably, the air-blocking cover also includes a handle, which is fixedly connected to the middle of the two baffles. The handle further increases the stability between the baffles, and the baffles can be pulled by holding the handle, making it easy to remove the baffles from the magnet.
[0012] Preferably, the spring clip includes a spring piece and a clip block. The lower end of the clip block is fixedly connected to the spring piece, and the clip block is matched with the reinforcing rod. The rear end of the spring piece is fixedly connected to the lower part of the cover. After the vent cover is closed downwards, the clip block is fastened to the reinforcing rod. The reinforcing rod acts on the baffle, which helps to keep the vent cover in a closed state.
[0013] Preferably, the snap fastener further includes a push button, which is fixedly connected to one end of the spring piece. Pressing the snap block downward causes the push button to act downward on the snap block, which in turn acts downward on the spring piece, causing the snap block to release the reinforcing rod, making it easier to fasten or unfasten the airlock cover.
[0014] Preferably, the magnet block includes a fixing sleeve and a magnet block body. The lower part of the fixing sleeve is fixedly connected to the body of the circulating cooling mixed-flow closed cooling tower, and the magnet block body is magnetically matched with the baffle. The magnetic attraction of the magnet block body to the baffle facilitates keeping the air-blocking cover in the extended state.
[0015] In summary, the technical effects and advantages of this utility model are as follows:
[0016] 1. Close the air-blocking cover downwards to reduce the air inlet at the rear of the suction hood. This allows the suction force of the side suction port of the circulating cooling mixed-flow closed cooling tower to act on the suction hood, causing it to draw in some gas from the front. Then, open the air-blocking cover to restore the rear suction state, making it easy to adjust the suction direction of the circulating cooling mixed-flow closed cooling tower.
[0017] 2. Use the rotating shaft sleeve to guide the air-blocking cover to flip. After flipping the air-blocking cover downwards, the air-blocking cover blocks the air at the rear of the cover, making it easier to transfer some of the suction force inside the air-blocking cover to the front.
[0018] 3. Flip the baffle downwards so that it blocks the side opening of the baffle, and conversely, fully open the rear opening of the hood to facilitate control of the suction hood.
[0019] 4. The handle further increases the stability between the baffles. Holding the handle and pulling the baffle makes it easy to remove the baffle from the magnet.
[0020] 5. After closing the vent cover downwards, the buckle will lock onto the reinforcing rod. The reinforcing rod will then act on the baffle to keep the vent cover closed.
[0021] 6. Press down on the buckle block to make the push button act downward on the buckle block, which in turn acts downward on the spring clip, causing the buckle block to release the reinforcing rod, making it easier to fasten or unfasten the airlock cover.
[0022] 7. The magnetic attraction of the magnetic block is used to hold the baffle open, making it easy to keep the air-blocking cover in the open position. Attached Figure Description

[0031] Reference Figure 1 and 2 The suction hood 2 includes a hood body 21 and a rotating shaft sleeve 22. The inner end of the hood body 21 is fixedly connected to the lower part of the circulating cooling mixed-flow closed-loop cooling tower body 1, and the rear part of the hood body 21 is located at the air intake of the circulating cooling mixed-flow closed-loop cooling tower body 1. The rotating shaft sleeve 22 is fixedly connected to the upper part of the hood body 21. The rotating shaft sleeve 22 guides the air-blocking cover 3 to flip down. After the air-blocking cover 3 is flipped downward, it blocks the air at the rear of the hood body 21.
[0032] Reference Figure 1 , 2 3. The air-blocking cover 3 includes a baffle 31 and a rotating shaft 34. The baffle 31 is symmetrically and fixedly connected to the rotating shaft 34. The rotating shaft 34 is rotatably mounted on the rotating shaft sleeve 22. The baffle 31 is magnetically attracted to the magnet block 5 and is fitted to the cover body 21. Flipping the baffle 31 downwards will block the side opening of the baffle 31, and vice versa will fully open the rear opening of the cover body 21.
[0033] Reference Figure 1 and 3 The air-blocking cover 3 also includes a reinforcing rod 32, which is fixedly connected between the two baffles 31 and is matched with the spring clip 4. The reinforcing rod 32 is used to increase the stability between the two baffles 31.
[0034] Reference Figure 1 and 3 The vent cover 3 also includes a handle 33, which is fixedly connected to the middle of the two baffles 31. The handle 33 further increases the stability between the baffles 31, and the baffles 31 are pulled by holding the handle 33.
[0035] Reference Figure 1 , 23 and 4, the spring clip 4 includes a spring piece 41 and a clip 42. The lower end of the clip 42 is fixedly connected to the spring piece 41, and the clip 42 is matched with the reinforcing rod 32. The rear end of the spring piece 41 is fixedly connected to the lower part of the cover 21. After the air-blocking cover 3 is closed downwards, the clip 42 is fastened onto the reinforcing rod 32, and the reinforcing rod 32 acts on the baffle 31.
[0036] Reference Figure 1 , 3 And 4, the spring buckle 4 also includes a push button 43, which is fixedly connected to one end of the spring piece 41. Pressing down on the buckle block 42 causes the push button 43 to act downward on the buckle block 42, which in turn causes the buckle block 42 to act downward on the spring piece 41, thus releasing the reinforcing rod 32.
[0037] Reference Figure 1 , 3 5. The magnet block 5 includes a fixing sleeve 51 and a magnet block body 52. The lower part of the fixing sleeve 51 is fixedly connected to the body 1 of the circulating cooling mixed flow closed cooling tower. The magnet block body 52 is magnetically matched with the baffle 31. The magnetic attraction of the magnet block body 52 on the baffle 31 keeps the air-blocking cover 3 in the open state.
[0038] Working principle: The air-blocking cover 3 is closed downwards, which reduces the air inlet at the rear of the suction hood 2. This causes the suction force of the side suction port of the circulating cooling mixed flow closed cooling tower body 1 to act on the suction hood 2, so that the suction hood 2 draws in some gas from the front. Then the air-blocking cover 3 is opened to restore the rear suction state, which makes it easy to adjust the suction direction of the circulating cooling mixed flow closed cooling tower body 1.
