Description

Technical Field

[0001] This utility model relates to the field of air cooler technology, specifically to an evaporative air cooler for chemical production. Background Technology

[0002] Evaporative air coolers are a type of high-efficiency and energy-saving cooling equipment that integrates water cooling and air cooling, as well as heat transfer and mass transfer processes, combining the advantages of both. They have advantages such as compact structure, high heat transfer efficiency, low investment, low operating costs, and convenient installation and maintenance. They have broad application prospects in industries such as oil refining, metallurgy, power, refrigeration, and light industry, and represent a new direction for the development of air cooling technology.

[0003] Among the existing technical solutions, the announcement number CN218270297U discloses an evaporative air cooler for chemical use, which includes a housing, a water collection tank buffer plate, a nozzle, a fan, a water tank, and condenser pipes. The left and right inner walls of the housing are fixedly connected with horizontal plates, and the lower end face of the horizontal plates is fixedly connected with a column. The outer wall of the column is fitted with a spring, and the outer wall of the column is slidably connected with a scraper frame. The upper and lower ends of the spring abut against the horizontal plate and the scraper frame, respectively.

[0004] To address the issue of manually cleaning scale from the water-cooling system inside air coolers to improve their performance, existing technology addresses the inconvenience of manually pulling a limit lever. This is achieved by a motor driving a worm gear, which in turn drives a rotating shaft. The shaft then rotates a disc, which in turn pulls a scraper frame via a connecting rod. A spring causes the scraper frame to move up and down, cleaning scale from the water collection tank. This automatic cleaning method eliminates the need for manual intervention. However, the long-term operation of the water-cooling system leads to scale buildup on the filter mechanism, eventually causing blockages. Utility Model Content

[0033] The present invention will be further described in detail below with reference to embodiments:

[0034] like Figure 1-6 As shown, the present invention provides the following technical solution. Example 1

[0035] This embodiment provides an evaporative air cooler for chemical production, including an air cooler housing 1. A fan cover 2 is fixedly installed on the top of the air cooler housing 1, and a fan assembly 3 is fixedly installed on the top of the fan cover 2. A material inlet 4 is fixedly installed on one side of the air cooler housing 1. An evaporator plate 5 is fixedly installed at the bottom of the inner cavity of the air cooler housing 1. A water storage tank 6 is fixedly connected to one side of the evaporator plate 5. A heat exchange tube bundle 7 is fixedly installed inside the evaporator plate 5. A circulation pipe port 8 is fixedly connected to one end of the evaporator plate 5. A transmission pipe 61 is fixedly connected to one end of the water storage tank 6. A sealing mechanism is fixedly connected to one end of the transmission pipe 61. A double-layer filter screen 66 is fixedly connected to the other end of the sealing mechanism. One side of the double-layer filter screen 66 is fixedly connected to the evaporator. On one side of the plate 5, the sealing mechanism includes a sealing ring 63. A connecting column 64 is fixedly connected to one side of the sealing ring 63. A fixed shaft 65 is threadedly connected to the other end of the connecting column 64. A snap-fit ​​shaft 651 is fixedly installed at the end of the fixed shaft 65 away from the connecting column 64. A rubber ring 652 is fixedly installed on the inner side of the snap-fit ​​shaft 651. The plate 5 is connected to the evaporator plate 5 through the water storage tank 6, which facilitates the injection of water from the water tank into the heat exchange tube bundle 7 for heat exchange. When the equipment is transporting water, the connecting column 64 and the fixed shaft 65 are fixedly connected to achieve the function of flange connection sealing. Then, the snap-fit ​​shaft 651 and the rubber ring 652 are mechanically connected to seal, thereby improving the sealing performance of the connection and preventing leakage of the circulation structure. Example 2

[0036] Based on Embodiment 1, this embodiment provides a technical solution: Preferably, a filter plate 614 is movably installed inside the transmission pipe 61. A cleaning mechanism is provided on one side of the filter plate 614. The cleaning mechanism includes a telescopic shaft 613. One end of the telescopic shaft 613 is fixedly connected to a fixing plate 612. One side of the fixing plate 612 is fixedly connected to a connecting rod 611. The other end of the connecting rod 611 is fixedly connected to one end of the transmission pipe 61. A cleaning ring 615 is fixedly installed inside the filter plate 614. A movable push rod 616 is movably installed inside the cleaning ring 615. One end of the movable push rod 616 is fixedly connected to a cleaning brush 617. The brush filters the water circulating through the filter plate 614 and the double-layer filter screen 66, thus filtering out dirt. To prevent clogging, the movable push rod 616 is periodically moved in conjunction with the telescopic shaft 613 to move the filter plate 614 and the dirt toward the fixed plate 612 until it stops between the transmission pipe 61 and the fixed plate 612. The movable push rod 616 then moves to push the cleaning brush 617 to move and sweep across the surface of the filter plate 614, thus facilitating the cleaning of dirt and increasing the anti-clogging function. Example 3

[0037] Based on Embodiment 1, this embodiment provides a technical solution: Preferably, a collection box 62 is fixedly connected to the bottom of one end of the transmission pipe 61, the top of the collection box 62 is located between the transmission pipe 61 and the fixed plate 612, a central shaft 618 is fixedly connected to the middle of the filter plate 614, and an inclined plate is fixedly installed on the outer side of the central shaft 618. The filter plate 614 and the dirt are driven to retract towards the fixed plate 612 by the telescopic mechanism, and the dirt is pushed towards the central shaft 618 by the cleaning mechanism. With the influence of the inclined angle of the inclined plate, the dirt is cleaned outward and falls into the collection box 62. This is beneficial for the device to further clean the dirt, prevent blockage during water circulation, and avoid affecting the normal operation of the device, thereby increasing the protective function of the device.

[0038] The working principle of this evaporative air cooler used in chemical production will be explained in detail below.

[0039] like Figure 1-6As shown, the water storage tank 6 is connected to the evaporator baffle 5, facilitating the injection of water from the tank into the heat exchange tube bundle 7 for heat exchange. During water transport, the connecting column 64 is fixedly connected to the fixed shaft 65, achieving a flange connection seal. Then, the snap-fit ​​shaft 651 and rubber ring 652 provide a mechanical seal, improving the sealing performance and preventing leakage in the circulation structure. The water circulation is filtered through the filter plate 614 and the double-layer filter screen 66, filtering out dirt. To prevent clogging, the telescopic shaft 613 periodically extends and retracts, moving the filter plate 614 and dirt towards the fixed shaft. The fixed plate 612 moves until it stops between the transmission pipe 61 and the fixed plate 612. The movable push rod 616 moves telescopically, pushing the cleaning brush 617 to move and sweep on the surface of the filter plate 614, achieving the function of convenient cleaning of dirt and helping to increase the anti-clogging function. The telescopic mechanism drives the filter plate 614 and dirt to retract towards the fixed plate 612. The cleaning mechanism pushes the dirt towards the central axis 618. Combined with the effect of the tilt angle of the inclined plate, the dirt is cleaned outward and falls into the collection box 62, which helps the device to further clean dirt and prevents blockage during water circulation, which would affect the normal operation of the device and increase the device's protective function.

[0040] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
