Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of denitration catalyst activation, in particular to a hoisting device for a denitration catalyst module. Background Art
[0002] During the use of denitrification catalyst, the pores are blocked due to the adsorption and bridging of large particles of fly ash or deposited fly ash. Due to the blockage of the pores, the reactants in the flue gas cannot further enter the inner surface of the catalyst pores, resulting in a decrease in activity. At the same time, the local flue gas velocity is too fast, and the insufficient residence time causes the pressure drop to increase and the wear to increase, resulting in the physical deactivation of the catalyst. Since the flue gas fly ash contains more compounds of elements such as K, Na, P, and As, they react with the active sites of the catalyst accordingly, thereby reducing the number of active sites participating in the denitrification reaction, causing the catalyst to be chemically deactivated.
[0003] During the activation process of the denitrification catalyst, the catalyst module needs to be hoisted. However, since there is usually no lifting fulcrum on the catalyst module, it is very inconvenient to move the catalyst module. Utility Model Content

[0025] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] Embodiment 1:
[0027] like Figure 1 , 2 In the illustrated embodiment, the bracket 101 supports each functional component. Specifically, the bracket 101 can be welded by high-strength bar steel, angle steel, channel steel or steel plate. The load-bearing platform 103 is slidably connected to the bracket 101 via the first slide 102, wherein the load-bearing platform 103 can be made of materials such as bar steel, channel steel or steel plate, and a second slide 104 is provided on the upper part of the load-bearing platform 103. Two suspension arms 106 are slidably connected to the upper part of the load-bearing platform 103 via the second slide 104, wherein the two suspension arms 106 can be welded by bar steel, angle steel or channel steel, and the clamping block provided at the bottom of each suspension arm 106 is used to clamp the denitration catalyst module.
[0028] The first driving mechanism disposed between the load-bearing platform 103 and the bracket 101 is used to drive the load-bearing platform 103 to slide up and down along the bracket 101. Specifically, an optional form of the first driving mechanism may be that the first driving mechanism includes a first driving motor 107, which is fixedly connected to the top of the bracket 101. The load-bearing platform 103 and the first driving motor 107 are powered by a movable pulley assembly 109 to reduce the load of the first driving motor 107. At the same time, a speed reducer may be disposed at the power output shaft of the first driving motor 107. In order to ensure the synchronization of the movement of both sides of the load-bearing platform 103, a transmission shaft 108 is disposed at the first driving motor 107. The end of the transmission shaft 108 away from the first driving motor 107 is rotatably connected to the bracket 101 via a bearing, and the transmission shaft 108 is used to reel in the draw rope.
[0029] The second drive motor disposed between each suspension arm 106 and the load-bearing platform 103 is used to drive each suspension arm 106 to slide on the load-bearing platform 103 to adjust the distance between the two suspension arms 106, thereby enabling the two suspension arms 106 to clamp the denitration catalyst module. Specifically, an optional form of the second drive mechanism is that the second drive mechanism includes a second drive motor, each of the second drive motors is fixedly connected to the suspension arm 106, a rack 105 or a chain is disposed on the upper portion of the load-bearing platform 103, and a gear or sprocket meshing with the rack 105 or the chain is disposed at the power output shaft of the second drive motor.
[0030] The trigger mechanism provided at each suspension arm 106 is used to detect whether the block at the bottom of each suspension arm 106 has been stuck at the bottom of the denitration catalyst. When the trigger mechanism at one suspension arm 106 is triggered, it means that the block at the suspension arm 106 at that side has been stuck at the bottom of the denitration catalyst to be moved. At this time, the second drive motor at the suspension arm 106 at that side stops executing the action to prevent the denitration catalyst module from being damaged.
[0031] When in use, the distance between the two hanging arms 106 is adjusted by the two second drive motors, so that the two hanging arms 106 can penetrate into the two sides of the denitration catalyst to be moved, and the height of the bearing platform 103 is adjusted by adjusting the first drive motor 107 to achieve the descent of the two hanging arms 106. When the blocks at the bottom of the two hanging arms 106 are lower than the bottom of the denitration catalyst to be moved, the two second drive motors are used to clamp the denitration catalyst module to be moved by the two hanging arms 106. The bearing platform 103 is raised to achieve the hoisting of the denitration catalyst module to be moved.
[0032] In order to facilitate the movement of the denitration catalyst after the denitration catalyst is hoisted, rollers and slideways adapted to the rollers are provided at the bottom of the bracket 101 .
[0033] Embodiment 2:
[0034] On the basis of Example 1, Figure 3 In the illustrated embodiment, in order to prevent the trigger sensor connected to the trigger mechanism from being damaged by contact with liquid during the process of placing the denitration catalyst module into the cleaning tank, the mechanical structure of the trigger mechanism includes a connecting rod hinged at each boom 106, the upper end of each connecting rod is used to trigger the trigger sensor, and the body of each connecting rod extends toward the other boom 106 at the hinge point, wherein a spring may be arranged between the upper end of each connecting rod and the boom 106, and the presence of the spring ensures that the bottom end of the connecting rod is located on the side of the boom 106 close to the other boom 106 in a natural state, and during the lifting process, as the boom 106 moves toward the denitration catalyst module, the denitration catalyst module contacts the bottom of the connecting rod, and when the block at the bottom of the boom 106 reaches the specified position, the upper end of the connecting rod just triggers the trigger sensor.
[0035] Embodiment 3:
[0036] On the basis of Example 1 or 2, Figure 4 In the illustrated embodiment, in order to prevent each boom 106 from contacting a lower obstacle when the load-bearing platform 103 descends, thereby damaging the boom 106 or other components, a safety device is slidably connected to each boom 106, and the safety device includes a support rod 111, a mounting seat 112 is provided on the outside of the boom 106, each support rod 111 is slidably connected to each boom 106 via the mounting seat 112, and a flange 110 is provided on the top of each support rod 111. At the same time, there is a certain gap between the bottom of each support rod 111 and the bottom of the boom 106. The existence of the flange 110 and the gap allows each support rod 111 to have a certain upward movement space relative to the boom 106. The upper end of the support rod 111 is used to trigger the second trigger sensor.
[0037] When in use, when the support rod 111 contacts an obstacle, it is blocked by the obstacle, causing the support rod 111 to slide upward relative to the boom 106, and the upper end of the support rod 111 triggers the second trigger sensor, which causes the first drive motor 107 to stop executing the action.
[0038] Wherein, the first trigger sensor and the second trigger sensor are any one of a contact switch, a reed switch, and an infrared radiation sensor.
[0039] Embodiment 4:
[0040] On the basis of any one of the embodiments 1-3, in order to prevent the suspension arm 106 from touching the denitration catalyst module and causing damage to the denitration catalyst module, a buffer layer is coated on the surface of each suspension arm 106 that contacts the object to be suspended. The buffer layer can be made of silicone or rubber.
[0041] Embodiment 5:
[0042] On the basis of any one of embodiments 1-4, in order to prevent foreign matter from entering during use, a protective shell is provided at the bracket 101, wherein, in order to facilitate observation of the internal conditions and maintenance, a plurality of inspection ports are provided at the protective shell.
[0043] The embodiments described above are only preferred specific implementation methods of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present utility model according to the technical solution and utility model concept of the present utility model, which should be covered by the protection scope of the present utility model.
