[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0024] Specific implementation examples are given below.
[0025] like Figures 1 to 3 As shown in the figure, a denitrification catalyst soaking in acid and alkali and then draining device according to an embodiment of the present invention includes a soaking tank 1, a limiting box 2 fixedly connected to the top of the soaking tank 1; threaded rods 3 are rotatably connected inside the limiting box 2, and two threaded rods 3 are arranged correspondingly; motors 6 are arranged at the bottom of the two threaded rods 3, and the motors 6 are fixedly connected to the bottom of the limiting box 2; movable blocks 4 are threadedly connected to the two threaded rods 3, and the two movable blocks 4 are arranged in parallel; limiting rods 5 are fixedly connected inside the limiting box 2, and two limiting rods 5 are arranged at the positions corresponding to the threaded rods 3, and the two limiting rods 5 are slidably connected to the movable blocks 4 respectively; U-shaped carrying rods 8 are fixedly connected between the two limiting rods 5, and multiple U-shaped carrying rods 8 are arranged in a linear array; a drain hole 9 is opened on the inner side wall of the soaking tank 1; during operation, the operator can place the denitrification catalyst to be soaked on the top of multiple U-shaped carrying rods 8, so that the catalyst comes into contact with the acid and alkali solutions in the soaking tank 1. After the catalyst is soaked, the working... Personnel can drive two motors 6 to move multiple U-shaped support rods 8 upwards, eventually causing the catalyst to detach from the solution and gradually dry. During this process, whenever motor 6 is driven, the threaded rod 3 fixed to the output end of motor 6 will rotate. Since the movable block 4 is threadedly connected to the threaded rod 3 and slidably connected to the limiting rod 5, the movable block 4 will move vertically inside the limiting box 2. Personnel can continue to drive the two motors 6 until the catalyst and multiple U-shaped support rods 8 are completely detached from the solution in the soaking tank 1. The drain hole 9 serves to drain water. This step controls the height of the movable block 4 by setting the motors 6 and the threaded rod 3, thereby controlling the height of the multiple U-shaped support rods 8 and the catalyst placed on top of the multiple U-shaped support rods 8. This provides convenience for personnel to perform catalyst draining operations, realizes automated catalyst draining operations, and helps improve the draining efficiency of denitrification catalysts and reduce labor costs.
[0026] like Figures 2 to 4As shown, a fixing rod 10 is fixedly connected to the side wall of two U-shaped carrying rods 8; a rotating clamping block 11 is rotatably connected to the side wall of the fixing rod 10, and multiple rotating clamping blocks 11 are arranged correspondingly; a first locking block 12 is fixedly connected to the side wall of the rotating clamping block 11; a second locking block 13 is slidably connected to the side wall of the fixing rod 10, and the second locking block 13 is sized corresponding to the first locking block 12; a threaded tube 14 is threadedly connected to the side wall of the fixing rod 10; during operation, the operator can use the clamping assembly composed of the rotating clamping block 11, the first locking block 12, the second locking block 13, and the threaded tube 14 to fix the catalyst placed on top of multiple U-shaped carrying rods 8. During the process, the operator can first place the catalyst on top of multiple U-shaped carrying rods 8, and then... The first locking block 12 and the second locking block 13 are engaged, and the threaded tube 14 is threadedly connected to the side wall of the fixing rod 10. The operator can adjust the position of the threaded tube 14 by rotating it, thereby controlling the contact relationship between the first locking block 12 and the second locking block 13. After the first locking block 12 and the second locking block 13 are separated, the operator can rotate the rotating clamping block 11 until it is rotated to the predetermined position. This step fixes the denitrification catalyst by setting up a clamping assembly composed of the rotating clamping block 11, the first locking block 12, the second locking block 13, and the threaded tube 14, thereby preventing the denitrification catalyst from shifting during the drying process and preventing it from floating during the soaking process, thus enhancing the practicality and stability of the device.
[0027] like Figure 4 As shown, movable rods 17 are slidably connected to the side wall of the rotating clamping block 11, and the two movable rods 17 are arranged correspondingly; clamping plates 16 and limiting plates 19 are respectively fixed to the two ends of the two movable rods 17; return springs 18 are respectively fixed between the two limiting plates 19 and the rotating clamping block 11; during operation, whenever the operator fixes the denitrification catalyst through the clamping assembly, the buffer assembly set at the end of the rotating clamping block 11 and composed of clamping plates 16, movable rods 17, return springs 18, and limiting plates 19 will first come into contact with the denitrification catalyst, wherein the clamping plates 16 contact the denitrification catalyst. After the agent is applied, the return spring 18, which is fixed between the limiting plate 19 and the rotating clamping block 11, will be stretched. When the buffer assembly is working, the return spring 18 can continuously provide stress to the clamping plate 16, so that the clamping plate 16 is tightly clamped on the surface of the denitrification catalyst. This step, by setting up a buffer assembly composed of the clamping plate 16, the movable rod 17, the return spring 18, and the limiting plate 19, assists the clamping assembly in fixing the denitrification catalyst, which enhances the stability and applicability of the clamping assembly of the device, helps to solve the problem of loose clamping of the clamping assembly, and avoids the denitrification catalyst from shifting during the drying and soaking process.
[0028] like Figure 4As shown, drainage grooves 20 are provided on the side wall of the clamping plate 16, and multiple drainage grooves 20 are arranged in a linear array. During operation, the multiple drainage grooves 20 arranged in a linear array reduce the contact area between the clamping plate 16 and the denitrification catalyst. During operation, some liquid adhering to the surface of the denitrification catalyst can fall down through the multiple drainage grooves 20. This step, by setting drainage grooves 20, avoids liquid adhering to the contact surface between the clamping plate 16 and the denitrification catalyst, enhances the practicality of the device, and helps to improve the drainage efficiency and drainage effect of the device.
[0029] like Figure 5 As shown, a stop pad 7 is fixedly connected to the side wall of the limit box 2, and multiple stop pads 7 are respectively set at the positions of the threaded rod 3 and the limit rod 5; multiple stop pads 7 are made of rubber; during operation, whenever the movable block 4 moves to the predetermined highest position under the action of the two motors 6, the top of the movable block 4 will contact multiple stop pads 7 made of rubber, and the multiple stop pads 7 can stop the movable block 4 from moving through this contact; this step avoids the movable block 4 from impacting the inner side wall of the limit box 2 by setting stop pads 7, and avoids stress concentration between components by using rubber material for the stop pads 7, which helps to extend the service life of the device and reduce maintenance requirements.
[0030] like Figure 3 and Figure 4 As shown, an operating handle 15 is fixedly connected to the side wall of the rotating clamping block 11, and the operating handle 15 is set according to the size of the rotating clamping block 11. During operation, the operator can rotate the rotating clamping block 11 with the help of the operating handle 15. In the process, the operator can first rotate the threaded tube 14 until the first locking block 12 and the second locking block 13 are separated. When the rotating clamping block 11 is rotated to the predetermined position by the operating handle 15, the operator can rotate the threaded tube 14 again until the first locking block 12 and the second locking block 13 are re-engaged. This step provides convenience for the operator's daily operation by setting the operating handle 15, improves the practicality and convenience of the device, and reduces the difficulty of using the device.
[0031] like Figures 2 to 4 As shown, the rotating clamping block 11, the first locking block 12, the second locking block 13, the threaded tube 14, the operating handle 15, the clamping plate 16, and the movable rod 17 are made of plastic. During operation, the plastic rotating clamping block 11, the first locking block 12, the second locking block 13, the threaded tube 14, the operating handle 15, and the clamping plate 16 can maintain their structural integrity after long-term immersion in acid and alkali solutions. This step, by using plastic for the rotating clamping block 11, the first locking block 12, the second locking block 13, the threaded tube 14, the operating handle 15, and the clamping plate 16, avoids corrosion of the components by acid and alkali solutions, and at the same time avoids contamination of the components with acid and alkali solutions, reducing safety hazards and helping to extend the service life of the device.
[0032] During operation, the operator places the denitrification catalyst to be soaked on top of multiple U-shaped support rods 8, allowing the catalyst to contact the acid and alkaline solutions in the soaking tank 1. After soaking, the operator drives two motors 6 to move the multiple U-shaped support rods 8 upwards, eventually detaching the catalyst from the solution and allowing it to gradually dry. During this process, whenever the motor 6 is driven, the threaded rod 3 fixed to the output end of the motor 6 will rotate. Since the movable block 4 is threadedly connected to the threaded rod 3 and slidably connected to the limiting rod 5, the movable block 4 will move vertically inside the limiting box 2. The operator can continue to drive the two motors 6 until the catalyst and multiple U-shaped support rods are completely removed from the solution and allowed to dry. The catalyst rod 8 is completely detached from the solution in the soaking tank 1. The drain hole 9 serves to drain the solution. Workers can use a clamping assembly consisting of a rotating clamping block 11, a first clamping block 12, a second clamping block 13, and a threaded tube 14 to fix the catalyst placed on top of the multiple U-shaped catalyst rods 8. During the process, workers can first place the catalyst on top of the multiple U-shaped catalyst rods 8. Then, because the first clamping block 12 and the second clamping block 13 are engaged, and the threaded tube 14 is threaded onto the side wall of the fixing rod 10, workers can adjust the position of the threaded tube 14 by rotating it, thereby controlling the contact relationship between the first clamping block 12 and the second clamping block 13. After the first clamping block 12 and the second clamping block 13 separate, the work... Personnel can rotate the rotating clamping block 11 until it reaches the predetermined position. Whenever a worker secures the denitrification catalyst using the clamping assembly, the buffer assembly, consisting of a clamping plate 16, a movable rod 17, a return spring 18, and a limiting plate 19, located at the end of the rotating clamping block 11, will first contact the denitrification catalyst. After the clamping plate 16 contacts the denitrification catalyst, the return spring 18, fixed between the limiting plate 19 and the rotating clamping block 11, will be stretched. During operation, the return spring 18 continuously provides stress to the clamping plate 16, ensuring that the clamping plate 16 is tightly clamped onto the surface of the denitrification catalyst. Multiple drainage grooves 20 arranged in a linear array reduce the contact between the clamping plate 16 and the denitrification catalyst. The contact area of the denitrifying agent is such that, during operation, some liquid adhering to the surface of the denitrification catalyst can fall through multiple drainage channels 20. Whenever the movable block 4 moves to the predetermined highest position under the action of the two motors 6, the top of the movable block 4 will contact multiple rubber-made stop pads 7. These stop pads 7 can stop the movable block 4 from moving through this contact. The operator can then rotate the clamping block 11 using the operating handle 15. During this process, the operator can first rotate the threaded tube 14 until the first locking block 12 and the second locking block 13 separate. When the clamping block 11 is rotated to the predetermined position using the operating handle 15, the operator can rotate the threaded tube 14 again until the first locking block 12 and the second locking block 13 re-engage.The rotating clamping block 11, first locking block 12, second locking block 13, threaded tube 14, operating handle 15, and clamping plate 16, all made of plastic, can maintain their structural integrity even after prolonged immersion in acidic or alkaline solutions.
