Description

Technical Field

[0001] This utility model relates to the field of distillation column air cooler equipment, and in particular to an adjustable louver for an air cooler. Background Technology

[0002] A distillation column is a tower-type gas-liquid contact device. By adding an air cooler to the top of the distillation column, it is possible to reduce energy consumption, utilize waste heat, reduce steam load, reduce costs, and precisely control the condensation temperature of the steam at the top of the column. The air cooler is usually composed of tube bundles, tube boxes, fan systems, and auxiliary structures. The auxiliary structures include support frames and louvers. The existing air cooler louver blades are usually adjusted manually, which is time-consuming and labor-intensive. Utility Model Content

[0003] To overcome the shortcomings of the existing problems mentioned above, this utility model provides an adjustable louver for an air cooler.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: an adjustable louver for an air cooler, including a louver frame, the louver frame being installed on the air cooler housing, a fan blade cavity being opened below the louver frame, a column being vertically arranged in the middle of the fan blade cavity, and a plurality of fan blades with equal spacing being arranged on both sides of the column and inside the fan blade cavity, the fan blades being rotatably connected to the louver frame and the column via a rotating shaft, an adjustment motor being fixedly connected to the upper end of the column near the air cooler housing, the movable end of the adjustment motor being threaded, and a component being fixedly connected to the movable end of the adjustment motor. A guide rod with parallel movable ends has a threaded sleeve fitted with a movable block. The movable block has a groove that fits with the guide rod. A movable rod is suspended below the movable block by a connecting rod. Rectangular support frames are set on both sides of the movable rod. Several connecting rods are set on the side of the rectangular support frame away from the movable rod. The two ends of the connecting rods are rotatably connected to the rectangular support frame and the middle position of the end of the fan blade back plate, respectively. The number of connecting rods is equal to the number of fan blades. In use, the adjusting motor drives the movable block to move up and down along the guide rod, which drives the rectangular support frame and connecting rods to move up and down, and drives the fan blades to rotate around the pivot, thereby adjusting the opening and closing angle of the fan blades.

[0005] Preferably, the top of the louver frame is rotatably connected to the air cooler housing via a hinge, and the two sides of the louver frame are slidably connected to the air cooler housing via self-locking load-bearing sliding supports. When the air cooler malfunctions or needs maintenance, the interior of the air cooler can be inspected by opening the louver frame without completely removing the air cooler housing, making it convenient to use.

[0006] Preferably, the maximum opening angle of the hinge and the self-locking load-bearing sliding support is 90°.

[0007] Preferably, a limit plate is fixedly connected to the bottom of the movable end of the regulating motor to prevent the movable block from excessively displacing and detaching from the movable end of the regulating motor.

[0008] Preferably, the fan blades are Z-shaped, which can guide the airflow entering the air cooler to form a more uniform flow field distribution, reduce turbulence and local resistance, and improve heat exchange efficiency.

[0009] The beneficial effect of this utility model is that adjusting the overall opening and closing angle of the fan blades by adjusting the motor is more time-saving and labor-saving than manual adjustment. Attached Figure Description

[0015] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0016] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0017] like Figure 1-3An adjustable louver for an air cooler is shown, comprising a louver frame 1 mounted on an air cooler housing 2. A fan blade cavity 3 is formed below the louver frame 1. A column 5 is vertically positioned in the middle of the fan blade cavity 3. Several fan blades 4 with equal spacing are arranged on both sides of the column 5 and within the fan blade cavity 3. The fan blades 4 are rotatably connected to the louver frame 1 and the column 5 via a pivot. An adjustment motor 6 is fixedly connected to the upper end of the column 5 near the air cooler housing 2. A thread 7 is formed on the movable end of the adjustment motor 6. A guide rod 8 parallel to the movable end is fixedly connected to one side of the movable end of the adjustment motor 6. A movable sleeve is fitted around the thread 7. The movable block 9 has a groove that fits with the guide rod 8. A moving rod 11 is suspended below the movable block 9 by a connecting rod 10. Rectangular support frames 12 are provided on both sides of the moving rod 11. Several connecting rods 13 are provided on the side of the rectangular support frame 12 away from the moving rod 11. The two ends of the connecting rods 13 are rotatably connected to the rectangular support frame 12 and the middle position of the end of the back plate of the fan blade 4, respectively. The number of connecting rods 13 is equal to the number of fan blades 4. In use, the adjusting motor 6 drives the movable block 9 to move up and down along the guide rod 8, which drives the rectangular support frame 12 and the connecting rods 13 to move up and down, which drives the fan blade 3 to rotate around the pivot, thereby adjusting the opening and closing angle of the fan blade 3.

[0018] The top of the louver frame 1 is rotatably connected to the air cooler housing 2 via hinge 14, and the two sides of the louver frame 1 are slidably connected to the air cooler housing 2 via self-locking load-bearing sliding supports 15. When the air cooler malfunctions or needs maintenance, the interior of the air cooler can be inspected by opening the louver frame 1 without completely removing the air cooler housing, making it convenient to use.

[0019] The maximum opening angle of the hinge 14 and the self-locking load-bearing sliding support 15 is 90°.

[0020] The bottom of the movable end of the regulating motor 6 is fixedly connected to a limiting plate 16 to prevent the movable block 9 from excessively displacing and detaching from the movable end of the regulating motor 6.

[0021] The fan blade 4 is Z-shaped, which can guide the airflow entering the air cooler to form a more uniform flow field distribution, reduce turbulence and local resistance, and improve heat exchange efficiency. Specific Implementation

[0022] In use, the adjusting motor 6 drives the movable block 9 to move up and down along the guide rod 8, which in turn drives the rectangular support frame 12 and the connecting rod 13 to move up and down, causing the fan blades 3 to rotate around the pivot. This allows the opening and closing angle of the fan blades 3 to be adjusted according to factors such as temperature and wind direction. When the air cooler malfunctions or needs maintenance, the inside of the air cooler can be inspected by opening the louver frame 1. It is convenient to use.

[0023] This design is ingenious. The overall opening and closing angle of the fan blades can be adjusted by regulating the motor, which is more time-saving and labor-saving than manual adjustment. In addition, the louver frame is connected to the air cooler shell by hinges and self-locking load-bearing sliding supports. When the air cooler malfunctions or needs maintenance, the interior of the air cooler can be inspected by opening the louver frame without completely disassembling the air cooler shell, making it convenient to use. The fan blades are Z-folded, which can guide the airflow into the air cooler to form a more uniform flow field distribution, reduce turbulence and local resistance, and improve heat exchange efficiency.

[0024] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
