Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a counter-flow cooling tower. Background Technology

[0002] Counterflow cooling towers play a vital role in industrial production and many other fields. Their main function is to dissipate the heat generated by the equipment into the atmosphere through the counterflow of water and air for heat exchange, so as to maintain the stable operation and normal temperature of the system.

[0003] Traditional counter-flow cooling towers typically consist of key components such as the tower body, water distribution system, water-spraying packing, ventilation equipment, and water collection tank. Among these, the water-spraying packing is a core component, and its performance directly affects cooling efficiency. Conventional cooling towers do not adequately consider the installation and replacement of the packing in their design, resulting in numerous inconveniences.

[0004] On the one hand, the connection between the packing and the tower body or other components is relatively fixed and complicated. For example, a large number of bolts and nuts are used for fastening, or some specially customized snap-fit ​​structures are used. These structures require a lot of time and manpower to install. Moreover, once the installation is completed, if you want to replace the packing later, the disassembly process is complicated and requires professional tools and skilled operation skills. This is extremely unfavorable for daily maintenance and replacement of packing in case of sudden damage.

[0005] On the other hand, the layout and fixation of the packing material within the tower body are often quite compact and lack flexible adjustment space, making it difficult for operators to perform operations within the limited space during replacement, further increasing the difficulty of replacement. Moreover, traditional designs do not fully consider the potential for blockage, aging, and damage to the packing material after long-term use, and do not provide convenient channels or reasonable structures to facilitate quick replacement of the packing material. As a result, if a problem occurs with the packing material, the entire cooling tower may need to be shut down for a long time for repair, seriously affecting production progress and the normal operating efficiency of the equipment. Utility Model Content

The side of the connecting plate closest to the packing contacts the cooling tower shell, and a handle is fixedly connected to the front of the connecting plate.

[0009] Preferably, in the above-mentioned counter-flow cooling tower, two limiting rods are installed on the inner wall of the strip-shaped cylinder, and a buckle plate is slidably connected to the two limiting rods. Two springs are installed on the side of the buckle plate near the cooling tower shell.

[0024] like Figures 1 to 6 As shown, a counter-flow cooling tower includes a cooling tower shell 1, a fan 2 installed on the top of the cooling tower shell 1, a fixing frame 4 installed on the inner wall of the cooling tower shell 1, a spray pipe 5 installed on the bottom surface of the fixing frame 4, four spray heads 12 connected to the bottom of the spray pipe 5, strip frames 13 fixedly connected to the inner walls of the four spray heads 12, rotating shafts 14 rotatably connected to the inside of the four strip frames 13, four rotating scrapers 15 fixedly connected to the outer surfaces of the four rotating shafts 14, packing 7 provided inside the cooling tower shell 1, a water collector 3 installed on the inner wall of the cooling tower shell 1, a water inlet pipe 6 installed inside the cooling tower shell 1, the water inlet pipe 6 connected to the spray pipe 5, four support rods 9 installed on the bottom surface of the cooling tower shell 1, a water collection box 10 installed at the bottom end of the four support rods 9, and four support feet 11 threadedly connected to the bottom surface of the water collection box 10.

[0025] The fixed frame 4 supports the spray pipe 5 to ensure the stability of the spray system; the support rod 9 cooperates with the support foot 11 to support the water collection box 10 and adjust the level of the tower body.

[0026] The set strip frame 13, rotating shaft 14 and rotating scraper 15 can rotate automatically under the impact of water flow. The rotating scraper 15 continuously scrapes the inner wall of the spray head 12 and the water outlet, effectively preventing scale and impurities from accumulating and clogging the spray holes.

[0027] The cooling tower shell 1 is equipped with a disassembly and assembly mechanism 8 inside and on its front. The disassembly and assembly mechanism 8 includes a connecting plate 801 fixedly connected to the front of the packing 7. A strip cylinder 809 is fixedly connected to the front of the connecting plate 801. Two fixed square rods 803 are slidably connected inside the connecting plate 801. Both fixed square rods 803 are fixedly connected to the inner wall of the cooling tower shell 1. A set of sliders 802 are slidably connected to each of the two connecting plates 801. Both sets of sliders 802 are fixedly connected to the outer surface of the packing 7. The side of the connecting plate 801 closest to the packing 7 is in contact with the cooling tower shell 1. A handle 804 is fixedly connected to the front of the connecting plate 801. Two limiting rods 81 are installed on the inner wall of the strip cylinder 809. Two limit rods 810 are slidably connected to a buckle plate 808. Two springs 811 are installed on the side of the buckle plate 808 near the cooling tower shell 1. Both springs 811 are installed on the inner wall of the strip cylinder 809. The positions of the two limit rods 810 are respectively sleeved in the two springs 811. A clamping plate 807 is in close contact with the buckle plate 808. A square box 805 is slidably connected to the clamping plate 807. The square box 805 is fixedly connected to the front of the cooling tower shell 1. Two sliding rods 806 are installed on the inner wall of the square box 805. Both sliding rods 806 are slidably connected to the inside of the clamping plate 807. A T-shaped pressing block 812 is installed on the buckle plate 808 and slidably connected to the inside of the strip cylinder 809.

[0028] The disassembly and assembly mechanism 8 guides the sliding of the packing 7 through the connecting plate 801, the fixed square rod 803, and the slider 802. The limit locking structure is formed by the strip cylinder 809, the limit rod 810, the spring 811, the buckle plate 808, the clamping plate 807, the square box 805, and the slide rod 806. It can be quickly disassembled and assembled without tools, which solves the problem of cumbersome replacement of traditional packing, shortens downtime maintenance time, and improves equipment operating efficiency.

[0029] Through the disassembly and assembly mechanism 8, the sliding cooperation between the connecting plate 801 and the fixed square rod 803, and the guiding support of the slider 802 for the packing 7, the packing 7 can be directly pulled out or inserted along the fixed square rod 803, avoiding the cumbersome disassembly process of bolt tightening or custom buckle fastening in traditional structures. At the same time, the spring 811 in the strip cylinder 809, together with the buckle plate 808 and the clamping plate 807, forms an automatic locking structure. When replacing, only the buckle plate 808 needs to be pressed and the clamping plate 807 needs to be slid. Disassembly and assembly can be completed without professional tools, significantly reducing downtime maintenance time.

[0030] Working Principle: Inside the cooling tower shell 1, a fan 2 is installed at the top, drawing air upwards during operation to form an upward airflow channel. The inlet pipe 6 introduces hot water to be cooled into the spray pipe 5, which sprays downwards through the spray head 12. At this time, the water flow and the upward airflow form a counter-current flow, achieving cooling through heat exchange. The strip frame 13, rotating shaft 14, and rotating scraper 15 inside the spray head 12 rotate under the impact of the water flow, scraping the inner wall of the spray head and the water outlet to prevent scale or impurities from clogging, ensuring uniform spraying. The cooled water falls into the packing 7, increasing the heat dissipation area and further exchanging heat with the air, finally flowing into the water collection box 10, completing the cooling cycle. A water collector 3 is installed on the inner wall of the shell to intercept water droplets carried in the airflow, reducing water loss.

[0031] When it is necessary to replace the packing 7, operate the disassembly and assembly mechanism 8: press the T-shaped pressing block 812 forward to drive the buckle plate 808. The buckle plate 808 slides on the limiting rod 810 inside the strip cylinder 809, compressing the spring 811, so that the buckle plate 808 disengages from the limiting groove of the clamping plate 807.

[0032] Then slide the card plate 807 upwards, and at this time hold the handle 804 to pull the connecting plate 801 and the packing 7 outwards along the fixed square rod 803. Since the slider 802 slides inside the connecting plate 801, it can help the packing 7 move smoothly. Finally, the packing 7 is taken out from the cooling tower shell 1.

[0033] During installation, the packing 7 is aligned with the fixed square rod 803 via the connecting plate 801 and inserted into the cooling tower shell 1 along the fixed square rod 803. The slider 802 slides into the connecting plate 801 simultaneously to ensure that the packing 7 is aligned.

[0034] Then press down on the T-shaped pressing block 812 to drive the buckle plate 808. The buckle plate 808 slides on the limiting rod 810. At this time, the locking plate 807 slides down along the sliding rod 806 and covers the buckle plate 808.

[0035] Release the retaining plate 808, and the spring 811 will reset, pushing the retaining plate 808 upwards to engage with the limiting groove of the retaining plate 807, thus fixing the packing 7. At this point, the connecting plate 801 is tightly attached to the inner wall of the cooling tower shell 1, completing the installation.
