Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of damper adjustment mechanisms, specifically to a reactor hot air damper adjustment mechanism. Background Technology
[0002] The HF reactor is the main reactor for the production of hydrofluoric acid and aluminum fluoride. Sulfuric acid and fluorite are added to the HF reactor at the same time, and the reaction produces hydrogen fluoride gas. This reaction is an endothermic reaction. The HF reactor body is designed with a jacket, and hot air at 560℃-600℃ is circulated inside. The hot air duct is generally designed with three inlets and four outlets, and there are seven regulating dampers to facilitate the adjustment of the furnace body temperature of each section of the HF reactor.
[0003] The hot air damper of the HF reactor relies on manual adjustment. Operators typically need to apply considerable force to adjust its opening, often using tools such as sledgehammers. This method is not only inefficient but also prone to adjustment errors. Furthermore, the hot air damper is usually located high up, posing significant operational difficulties and safety hazards during winter operations in icy or snowy weather. Utility Model Content
[0004] In view of this, the present invention provides a reactor hot air damper adjustment mechanism to solve the problems of high difficulty, poor accuracy and safety hazards in adjusting the hot air damper of the HF reactor.
[0005] This utility model provides a reactor hot air damper adjustment mechanism, including:
[0006] support;
[0007] The adjustment mechanism includes an adjustment rod movably mounted on the bracket, the adjustment rod extending along the height direction to be driven to a damper regulating valve; it also includes a drive member driven to the adjustment rod via a screw and nut structure, the drive member being adapted to drive the adjustment rod to move relative to the bracket along the height direction, wherein the adjustment rod is used to drive the damper regulating valve to adjust the damper opening.
[0008] Optionally, the support includes pillars and crossbeams. One end of each of the two pillars is connected to the bottom of opposite ends of the crossbeam, and the other end is fixedly connected to the support surface. A guide hole extending along the height direction is provided on the crossbeam, and the adjusting rod is movably disposed in the guide hole.
[0009] Optionally, the lead screw nut structure includes an external thread disposed on a portion of the outer surface of the adjusting rod, and an adjusting nut disposed on the driving member. The driving member is an adjusting wheel coaxially disposed with the adjusting rod. The adjusting wheel and the adjusting nut are welded together, and the internal thread of the adjusting nut engages with the external thread.
[0010] Optionally, the adjusting nut is slidably engaged with the surface of the crossbeam.
[0011] Optionally, the adjusting nut is slidably engaged with the upper surface of the crossbeam, and a limiting nut is provided at one end of the adjusting rod that extends out of the guide hole and is located on the lower surface of the crossbeam, and the limiting nut is in contact with the lower surface of the crossbeam.

[0013] Optionally, the adjusting nut and the limiting nut are T-nuts.
[0014] Optionally, the adjusting rod is provided with an opening degree mark, and the bracket is provided with an indicator corresponding to the opening degree mark.
[0015] Optionally, the adjusting rod is fixedly connected to the reversing rod of the damper regulating valve, and is adapted to drive the reversing rod to swing along the height direction.
[0016] Beneficial effects:
[0017] The reactor hot air damper adjustment mechanism provided by this utility model includes: a support and an adjustment mechanism. The adjustment mechanism includes an adjustment rod movably mounted on the support, which extends along the height direction to be driven to connect with a damper regulating valve; it also includes a drive component driven to the adjustment rod via a screw and nut structure, the drive component being adapted to drive the adjustment rod to move relative to the support along the height direction, wherein the adjustment rod is used to drive the damper regulating valve to adjust the damper opening.
[0018] The bracket can be mounted on the support surface, and the adjusting rod extends along the height direction and connects to the damper regulating valve.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] like Figure 1 As shown, this embodiment provides a reactor hot air damper adjustment mechanism, including: a support 1 and an adjustment mechanism.
[0025] The adjustment mechanism includes an adjustment rod 21 movably mounted on the bracket 1. The adjustment rod 21 extends along the height direction to be driven to the damper regulating valve. It also includes a drive component that is driven to the adjustment rod 21 through a screw and nut structure. The drive component is adapted to drive the adjustment rod 21 to move relative to the bracket 1 along the height direction. The adjustment rod 21 is used to drive the damper regulating valve to adjust the damper opening.
[0026] The bracket 1 can be mounted on a support surface 4, which can be the ground. The adjusting rod 21 extends along the height direction and connects to the damper regulating valve, allowing the operator to operate the damper regulating valve from the support surface 4 via the adjusting rod 21 to adjust the damper opening. Specifically, the drive component is connected to the adjusting rod 21 via a screw and nut structure. The operator can control the adjusting rod 21 to move along the height direction by rotating the drive component. Compared to traditional methods of adjusting damper opening, converting rotary motion into linear motion is more labor-saving and reduces the difficulty of adjusting the hot air damper 3. Since the distance the adjusting rod 21 moves along the height direction is related to the rotation angle and number of rotations of the drive component, the moving distance of the adjusting rod 21 can be accurately determined, which is more conducive to controlling the adjustment accuracy. The structure is simple and easy to operate.
[0027] In addition, the adjusting rod 21 can be directly extended to connect with the damper regulating valve, so that the operator can operate it without having to move to the corresponding height of the damper regulating valve, which improves safety.
[0028] like Figure 1 As shown, in this embodiment, the support 1 includes two pillars 12 and a crossbeam 11. One end of each pillar 12 is connected to the bottom of opposite ends of the crossbeam 11, and the other end is fixedly connected to the support surface 4. The pillars 12 can support the crossbeam 11 at a certain distance from the support surface 4, forming a space between the crossbeam 11 and the support surface 4 for the adjustment rod 21 to move, while also preventing the support 1 from shifting or shaking. A guide hole extending along the height direction is provided on the crossbeam 11, and the adjustment rod 21 is movably disposed in the guide hole, moving along the height direction under the guidance of the guide hole.
[0029] Of course, the aforementioned crossbeam 11 can also be replaced with a flat plate, with one end of each of the multiple support columns connected to the corner of the flat plate, and guide holes extending along the height direction are provided on the flat plate as above.
[0030] like Figure 1As shown, in this embodiment, the lead screw nut structure includes an external thread 211 on a portion of the outer surface of the adjusting rod 21, and an adjusting nut 23 on the driving component. The driving component is an adjusting wheel 22 coaxially arranged with the adjusting rod 21. The adjusting wheel 22 and the adjusting nut 23 are welded together, and the internal thread of the adjusting nut 23 engages with the external thread 211. By rotating the adjusting wheel 22, the adjusting nut 23 is driven to rotate. The internal thread of the adjusting nut 23 engages with the external thread of the adjusting rod 21, thereby driving the adjusting rod 21 to move along the height direction. For example, when the adjusting wheel 22 is rotated clockwise, the adjusting nut 23 rotates clockwise simultaneously, the adjusting rod 21 moves upward and pushes the damper regulating valve, thereby increasing the opening of the damper. When the adjusting wheel 22 is rotated counterclockwise, the adjusting nut 23 rotates counterclockwise simultaneously, the adjusting rod 21 moves downward and pulls the damper regulating valve, thereby decreasing the opening of the damper. Alternatively, when the adjusting wheel 22 rotates clockwise, the adjusting rod 21 moves downward and reduces the opening of the damper; when the adjusting wheel 22 rotates counterclockwise, the adjusting rod 21 moves upward and increases the opening of the damper. This can be determined based on the threaded fit between the adjusting rod 21 and the adjusting nut 23, as long as the adjusting rod 21 can move along the height direction, without any specific restrictions.
[0031] like Figure 1 As shown, in this embodiment, the adjusting nut 23 slides on the surface of the crossbeam 11, and the relative height between the adjusting nut 23 and the crossbeam 11 remains unchanged, ensuring that the adjusting rod 21 moves relative to the crossbeam 11 in the height direction.
[0032] like Figure 1 As shown, in this embodiment, the adjusting nut 23 slides on the upper surface of the crossbeam 11. The adjusting rod 21 extends out of the guide hole and is provided with a limiting nut 24 at one end located on the lower surface of the crossbeam 11. The limiting nut 24 contacts the lower surface of the crossbeam 11. The limiting nut 24 can lock the adjusting rod 21 on the crossbeam 11. For example, after the adjusting rod 21 moves to a position that meets the opening requirements of the damper, the limiting nut 24 can be rotated towards the lower surface of the crossbeam 11. Since the adjusting nut 23 contacts the upper surface of the crossbeam 11, the adjusting rod 21 can be locked through the cooperation of the limiting nut 24 and the adjusting nut 23. When it is necessary to adjust the opening of the damper, the limiting nut 24 can be moved away from the lower surface of the crossbeam 11 to engage the locked state.
[0033] like Figure 1 As shown, in this embodiment, an auxiliary wheel is welded onto the limiting nut 24 and is coaxially arranged with the adjusting rod 21. The auxiliary wheel can facilitate the control of the rotation of the limiting nut 24. Of course, the limiting nut 24 can also be rotated by tools such as an adjustable wrench.
[0034] like Figure 1As shown, in this embodiment, the adjusting nut 23 and the limiting nut 24 are T-shaped nuts. T-shaped nuts have the characteristics of preventing loosening, preventing vibration, and having a strong load-bearing capacity, thereby improving the stability of the adjusting damper opening and limiting the damper opening.
[0035] like Figure 1 As shown, in this embodiment, the adjusting rod 21 is provided with an opening degree mark, and the bracket 1 is provided with an indicator corresponding to the opening degree mark. For example, the indicator can be a pointer, and the opening degree mark can be a scale line set along the height direction. The pointer is parallel to the scale line, and the scale line corresponding to the pointer can be the height distance of the top of the adjusting rod 21, or it can be the opening size of the hot air damper 3. Since there is a direct relationship between the top height of the adjusting rod 21 and the opening of the hot air damper 3, the scale line can be increased sequentially from top to bottom, which makes it easier for the operator to judge the opening of the damper.
[0036] like Figure 1 As shown, in this embodiment, the adjusting rod 21 is fixedly connected to the reversing rod 31 of the damper regulating valve, and is suitable for driving the reversing rod 31 to swing along the height direction. For example, when the adjusting rod 21 drives the reversing rod 31 to swing upward, the opening of the damper increases, and when the adjusting rod 21 drives the reversing rod 31 to swing downward, the opening of the damper decreases.
[0037] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
