Description

Technical Field

[0001] This utility model relates to the field of blower technology, and in particular to a large industrial cooling blower. Background Technology

[0002] The single-stage high-speed centrifugal fan is a completely new concept blower. It employs three core high-end technologies: an ultra-high-speed direct-drive motor, air-suspended bearings, and a high-precision single-stage centrifugal impeller, ushering in a new era of high-efficiency, high-performance, low-noise, and low-energy-consumption blowers. It is a new generation of high-tech civilian product meticulously developed using aerospace turbomachinery design experience. It is widely used in wastewater treatment, papermaking and printing, chemical industry, pneumatic conveying, and other industries.

[0003] Existing air intake ducts are mostly fixed straight cylinders or single-angle bends, and the air intake direction cannot be adjusted. In complex environments such as industrial workshops, where there are equipment obstructions, localized high-temperature areas, or areas with concentrated dust, fixed-direction air intake may result in: failure to draw in low-temperature clean air, directly reducing cooling efficiency; or air intake being blocked by obstacles, creating negative pressure or eddies within the duct, resulting in very little actual air intake and causing the blower to idle and consume energy. Utility Model Content

[0004] The purpose of this invention is to provide a large industrial cooling blower that addresses the shortcomings of existing technologies.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A large industrial cooling blower includes a main housing, an air inlet duct connected to the left end of the main housing, and an exhaust box connected to the right end of the main housing. The exhaust box has a grid structure wall and a centrifugal blower installed inside the exhaust box to draw air from the main housing to the exhaust box. The air inlet duct extends upward, and an air duct cover is installed at the top of the air inlet duct. The air duct cover is formed with multiple protruding air inlet tubes. An air guide seat is installed on the air inlet tube, and a circular connecting tube is installed at the bottom of the air guide seat. The circular connecting tube is rotatably connected to the air inlet tube. The cross-sectional shape of the air guide seat is 1 / 4 circle, and the air guide seat is formed with an air guide port. Multiple horizontally arranged adjusting shafts are installed on the air guide ports. Air guide vanes are installed on the adjusting shafts along the length direction, and the adjusting shafts can rotatably adjust the tilt angle of the air guide vanes.

[0006] Furthermore: Adjustment holes for installing adjustment shafts are formed on both sides of the air guide. One of the adjustment holes is fitted with a bearing seat. One end of the adjustment shaft is installed in the bearing seat, and the other end of the adjustment shaft extends outward through the adjustment hole.

[0007] Furthermore: An adjustment mechanism is provided outside the air guide seat to synchronously adjust the tilt angle of all air guide vanes. The adjustment mechanism includes a rotating block installed on the part extending outward from the adjustment hole.

[0008] Furthermore, the adjustment mechanism also includes a driving component that drives the rotating block to rotate. The driving component includes a first driving rod and a second driving rod arranged at intervals, both of which are connected to the rotating block. The driving component includes an adjustment handle that is oscillatingly mounted on the first driving rod.

[0009] Furthermore: the first drive rod and the second drive rod are arranged in parallel at intervals, and the rotating block is provided with a first connection point that is movably connected to the first drive rod and a second connection point that is movably connected to the second drive rod.

[0010] Furthermore: the air inlet duct is equipped with a damping ring, and the circular connecting cylinder is rotatably connected to the air inlet duct with damping.

[0011] Furthermore: the outer ring wall is formed with a concave first annular groove, and the inner ring wall of the circular connecting cylinder is formed with a concave second annular groove. The first annular groove and the second annular groove are radially aligned. The damping ring is fitted onto the first annular groove and simultaneously makes frictional contact with the second annular groove.

Detailed Implementation

[0021] The present invention will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1-5 As shown, a large industrial cooling blower includes a main housing 3, an air inlet duct 1 connected to the left end of the main housing 3, and an exhaust box 35 connected to the right end of the main housing 3. The exhaust box 35 has a grid structure 36 on its wall, and a centrifugal blower 37 is installed inside the exhaust box 35 to draw air from the main housing 3 to the exhaust box 35.

[0023] The air inlet duct 1 extends upward, and an air duct cover 11 is installed on the top of the air inlet duct 1. The air duct cover 11 is formed with multiple protruding air inlet tubes 12. An air guide seat 13 is installed on the air inlet tube 12, and a circular connecting tube 14 is installed at the bottom of the air guide seat 13. The circular connecting tube 14 is rotatably connected to the air inlet tube 12. The cross-sectional shape of the air guide seat 13 is 1 / 4 circle. The air guide seat 13 is formed with an air guide port 18. Multiple horizontally arranged adjusting shafts 19 are installed on the air guide ports 18. Air guide vanes 20 are installed on the adjusting shafts 19 along the length direction. The adjusting shafts 19 can rotatably adjust the tilt angle of the air guide vanes 20.

[0024] The rotatable design of the air guide seat 13 and the tilt angle adjustment function of the air guide vane 20 form a dual adjustment mechanism. By rotating the air guide seat 13, the overall air intake direction can be changed, such as horizontal, oblique, or vertical air intake. The tilt angle driven by the adjustment shaft 19 can precisely control the airflow speed and distribution. When the heat source is concentrated in a specific area, the airflow can be directed to the target location by adjusting the direction of the air guide seat 13. At the same time, the wind speed can be controlled by the angle of the air guide vane 20, avoiding the airflow waste problem of traditional fixed air guide structures. The exhaust box 35 adopts a grille structure 36 and has a built-in centrifugal blower 37. The air drawn into the exhaust box 35 by the centrifugal blower 37 is discharged outward through the grille structure 36 to prevent direct blowing.

[0025] Furthermore, adjustment holes for mounting adjustment shafts 19 are formed on both sides of the air guide 18. One adjustment hole is fitted with a bearing seat, one end of the adjustment shaft 19 is mounted to the bearing seat, and the other end of the adjustment shaft 19 extends outward through the adjustment hole. An adjustment mechanism 2 is provided outside the air guide seat 13 to synchronously adjust the tilt angle of all air guide vanes 20. The adjustment mechanism 2 includes a rotating block 38 mounted on the outwardly extending part of the adjustment hole. By driving the rotating block 38, the adjustment shaft 19 is rotated. When the adjustment shaft 19 rotates, the tilt angle of the air guide plate can change, thereby adjusting the tilt angle of the air guide vanes 20. The air velocity and air volume can be adjusted accordingly by controlling the angle of the air guide vanes 20.

[0026] Specifically, the adjustment mechanism 2 also includes a driving component that drives the rotating block 38 to rotate. The driving component includes a first driving rod 21 and a second driving rod 22 arranged at intervals, both of which are connected to the rotating block 38. The driving component includes an adjustment handle 23 that is oscillatingly mounted on the first driving rod 21, and an elastic plate 27 is movably connected between the adjustment handle 23 and the second driving rod 22. In the initial state, the air guide vane 20 is unfolded to a horizontal state. When it needs to be adjusted to an inclined state, the adjustment handle 23 is oscillated. At this time, the elastic plate 27 has elastic force and deforms and is compressed. The first driving rod 21 and the second driving rod 22 do not move. When the elastic plate 27 is compressed to the point of starting to rebound, the first driving rod 21 and the second driving rod 22 move relative to each other under the drive of the adjustment handle 23 and the elastic plate 27, causing the rotating block 38 to rotate. The adjustment shaft 19 mounted on the rotating block 38 rotates to adjust the air guide vane 20. The elastic plate 27 provides elastic force, and the air guide vane 20 has better stability after reaching the required tilt angle when rotating, making it less prone to rotation and able to maintain the tilt angle for air guiding.

[0027] The first drive rod 21 and the second drive rod 22 are arranged in parallel and spaced apart. The rotating block 38 is provided with a first connection point 28 that is movably connected to the first drive rod 21 and a second connection point 29 that is movably connected to the second drive rod 22. The swing adjustment handle 23 swings around the first drive rod 21. The end of the adjustment handle 23 will continuously move closer to or away from the connection between the second drive rod 22 and the elastic plate 27. When it moves closer, the elastic plate 27 will be compressed. After reaching the closest point, the adjustment handle 23 continues to swing. At this time, the end of the adjustment handle 23 will move away from the connection between the second drive rod 22 and the elastic plate 27, so that the first drive rod 21 and the second drive rod 22 move relative to each other. Through the movable connection of the first connection point 28 and the second connection point 29, the rotating block 38 rotates accordingly.

[0028] Preferably, the adjusting handle 23 is provided with a movable connecting groove 24 along its path, which is rotatably connected to the first drive rod 21. The first drive rod 21 is provided with a first rotating rod 25 connected to the movable connecting groove 24. The adjusting handle 23 is mounted on the movable connecting groove 24 via the first rotating rod 25, and the adjusting handle 23 can swing around the first rotating rod 25. The second drive rod 22 is provided with a second rotating rod 26 rotatably connected to one end of the elastic plate 27. The elastic plate 27 can swing around the second rotating rod 26, and the other end of the elastic plate 27 is rotatably connected to the end of the adjusting handle 23. In this embodiment, when the air guide plate is closed, when the adjusting handle 23 is driven upward, the elastic plate 27 initially provides elastic force to provide stability.

[0029] Preferably, the elastic sheet 27 is made of 304 stainless steel.

[0030] Preferably, the first connection point 28, which is movably connected to the first drive rod 21, and the second connection point 29, which is movably connected to the second drive rod 22, are both shaft hole movable connection structures.

[0031] Furthermore, the air inlet duct 12 is fitted with a damping sleeve 15, and the circular connecting cylinder 14 is rotatably connected to the air inlet duct 12 with damping. The outer ring wall is formed with a concave first annular groove 16, and the inner ring wall of the circular connecting cylinder 14 is formed with a concave second annular groove 17. The first annular groove 16 and the second annular groove 17 are radially aligned. The damping sleeve 15 is fitted onto the first annular groove 16, and simultaneously makes frictional contact with the second annular groove 17. By increasing the contact area, the damping force distribution is made more uniform. The circular connecting cylinder 14 can rotate to the required angle, allowing the air guide 18 to adjust its angle according to the airflow direction. Due to the frictional action of the damping sleeve 15, a relatively large force is required during adjustment. Therefore, after adjustment, the free rotation of the air guide seat 13 can be effectively suppressed; the air guide seat 13 can maintain the adjusted angle.

[0032] Specifically, a cooling device 30 for cooling the intake air is installed inside the main unit housing 3. The cooling device 30 includes cooling plates 31 installed on the left and right sides of the main unit housing 3, and a cooling rod 32 detachably installed between the two cooling plates 31. The cooling rod 32 is filled with ice. In this embodiment, if it is necessary to cool the gas in the blower and provide it to the room for cooling, the cooling rod 32 can be inserted into the blower. After the airflow enters the main unit housing 3 from the air inlet duct 1, it needs to pass through the dense gaps between the cooling rods 32 and make full contact with the surface of the cooling rods 32. The temperature inside the main unit housing 3 is reduced. When the airflow passes through, the temperature decreases, and when it is drawn out by the centrifugal blower, the cooling effect is achieved, and the indoor temperature can be reduced.

[0033] Preferably, there are multiple cooling rods 32, and the cooling plate 31 is formed with multiple positioning holes 33. Positioning sleeves 34 are formed in the positioning holes 33, with each positioning sleeve 34 extending partially into and out of the positioning hole 33. The positioning sleeves 34 of the two cooling plates 31 are coaxially aligned. Therefore, when installing the cooling rods 32, the positioning sleeves 34 can act as guides. The portion of the positioning sleeve 34 extending outward from the positioning hole 33 forms an insertion / removal guide port, allowing the operator to quickly align the cooling rods 32 with the positioning holes 33, thus reducing installation and removal time. The cooling rods 32 can be directly inserted and removed through the positioning sleeves 34, eliminating the need for bolts, clips, or other fastening components.

[0034] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0035] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
