[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0025] Embodiment 1

[0026] See also Figure 1-6The utility model provides a technical solution: a dust prevention device for a diffusion tank of cementing equipment, comprising a tank body 1, the top of which is connected to an exhaust pipe 2, which is fixed by welding or threaded connection to ensure sealing and stability. Such a connection method allows the exhaust pipe 2 to reliably handle the gas rising from the tank body 1. The surface of the tank body 1 is connected to an inlet 3, which is connected to an external pipeline by a flange connection, which is convenient for installation and maintenance, while ensuring the smooth entry of cement powder and other substances. A slot 4 is provided inside the exhaust pipe 2, and a plug plate 5 is slidably connected to the inner wall of the slot 4. A guide rail sliding structure is adopted to enable the plug plate 5 to slide smoothly and reduce wear. When cement powder is raised, the filter screen 20 provided can filter the cement powder, thereby preventing the cement powder from being directly exhausted through the exhaust pipe 2. A bent plate 6 is fixedly installed on the side of the plug plate 5, which is fixed by bolts to enhance the reliability of the structure. The surface of the exhaust pipe 2 is rotatably connected with a threaded rod 7, and an adjustment cap 8 is fixedly installed at one end of the threaded rod 7. The surface of the adjustment cap 8 is provided with grooves 9, and the grooves 9 are arranged in a circular shape on the surface of the adjustment cap 8, which is convenient for the operator to grasp and rotate. The adjustment cap 8 is made of PP plastic, which provides sufficient strength and chemical corrosion resistance, so that after the filter 20 is blocked, the staff only needs to operate it by twisting the threaded rod 7 through the adjustment cap 8. At this time, since the bent plate 6 is provided with threads, and the threads are engaged with the threaded rod 7, the rotation of the threaded rod 7 can drive the bent plate 6 to move, and then the bent plate 6 drives the plug plate 5 to slide in the slot 4. This sliding mechanism allows the plug plate 5 to smoothly switch the filter 20, and quickly replace the blocked filter 20 without disassembling the entire device, which significantly reduces the downtime of the equipment and the complexity of maintenance work.

[0027] See also Figure 1-6 , a filter screen 20 is fixedly installed on the surface of the plug plate 5, which is fixed by a buckle or a clamp, so that the filter screen 20 can be replaced conveniently and quickly. This design ensures that the equipment can continue to operate without being disturbed by obstruction, thereby ensuring the continuity and efficiency of the flue gas treatment process. The water pipe 13 is connected to an external water source, and then water enters through the water pipe 13, and then the water enters the cross pipe 14 through the rotating sleeve 12 and the rotating shaft 11 in turn. This water flow path design effectively suppresses the lifting of cement powder during the operation of the cementing equipment. The water is finally sprayed out from the nozzle 15, which is designed to be rotatable. The spraying of the nozzle 15 can avoid the lifting of cement powder. At the same time, the staff can rotate the worm 18, and the worm 18 drives the worm wheel 17 meshing with it to rotate, and the worm wheel 17 can then drive the rotating shaft 11 and the cross pipe 14 to rotate, and the cross pipe 14 can then drive the nozzle 15 to rotate, increasing the coverage of the water mist, thereby more effectively controlling the lifting of dust. In addition, the rotation of the rotating shaft 11 not only drives the nozzle 15, but also can clean the filter 20 through the brush plate 19 connected thereto. This automatic cleaning mechanism reduces the need for manual cleaning of the filter 20, extends the service life of the filter 20, and reduces maintenance time and cost.

[0028] Embodiment 2

[0029] See also Figure 4-5 The inner wall of the tank body 1 is provided with a dust reduction mechanism, which includes a center plate 10, which is fixedly mounted on the inner wall of the tank body 1. The fixed installation can be welded or bolted to enhance the stability and durability of the structure. The center plate 10 is rotatably connected to a rotating shaft 11 inside, and a rotating sleeve 12 is rotatably connected to the surface of the rotating shaft 11. This rotational connection can be achieved through a ball bearing or a sliding bearing, so that the rotating shaft 11 can still rotate smoothly when it is subjected to horizontal and vertical loads. The surface of the rotating sleeve 12 is connected to a water pipe 13, which is used to introduce an external water source into the interior of the equipment and enter the water through the water pipe 13. The water pipe 13 can be made of high-strength plastic or metal to adapt to high-pressure water flow. A horizontal pipe 14 is fixedly mounted on the bottom surface of the center plate 10, and a nozzle 15 is connected to the surface of the horizontal pipe 14. The nozzle 15 can be connected to the horizontal pipe 14 by a threaded connection or a quick connector, which is convenient for disassembly and maintenance of the nozzle 15. The bottom surface of the center plate 10 is fixedly mounted with a housing 16, the surface of the rotating shaft 11 is fixedly mounted with a worm gear 17, and the inner wall of the housing 16 is rotatably connected with a worm 18. A handle is fixedly mounted on one end of the worm 18, and the worm gear 17 meshes with the worm 18 to provide precise rotation control. This meshing method can be helical gear meshing or spur gear meshing, which improves the transmission efficiency and durability of the equipment. A brush plate 19 is fixedly mounted on the top of the rotating shaft 11, and the brush plate 19 fits with the filter screen 20. This fit can be achieved through a magnetic fixation or clamping mechanism, so that the filter screen 20 can be quickly replaced or cleaned.

[0030] Working principle: when cement powder is raised, the filter 20 can filter the cement powder, thereby preventing the cement powder from being exhausted directly through the exhaust pipe 2. When the filter 20 is blocked, the staff only needs to screw the threaded rod 7 through the adjusting cap 8. At this time, since the bent plate 6 is provided with threads, the threaded rod 7 can drive the bent plate 6 to move, and the bent plate 6 then drives the plug plate 5 to slide in the slot 4. During the sliding process of the plug plate 5, the filter 20 can be switched, so that another filter 20 can be replaced in the exhaust pipe 2 for use. When the filter 20 is blocked, it can be quickly prevented from being blocked. The utility model makes the replacement process of the filter 20 simple and quick. When a filter 20 is blocked, the staff can The filter screen 20 can be quickly switched to another clean filter screen 20 by rotating the adjusting cap 8 and the threaded rod 7 without disassembling the entire device, thereby reducing the downtime of the equipment, reducing the complexity and time required for maintenance work, thereby reducing the labor intensity and maintenance cost of the operator, and because the filter screen 20 can be quickly replaced when blockage is found, it is ensured that the equipment can continue to operate without being disturbed by blockage, so that the continuity and efficiency of the flue gas treatment process can be guaranteed. The water pipe 13 is connected to an external water source, and then water enters the water through the water pipe 13, and then the water enters the horizontal pipe 14 through the rotating sleeve 12 and the rotating shaft 11 in turn, and finally sprayed out from the nozzle 15. The lifting of cement powder can be avoided. At the same time, the staff can rotate the worm 18, and the worm 18 can drive the worm wheel 17 meshing with it to rotate, and the worm wheel 17 can then drive the rotating shaft 11 and the cross pipe 14 to rotate, and the cross pipe 14 can then drive the nozzle 15 to rotate. At this time, the rotating spraying of the nozzle 15 can more effectively avoid the lifting of cement powder, and the rotation of the rotating shaft 11 can drive the brush plate 19 to rotate. At this time, the brush plate 19 can rub the filter screen 20, so that the filter screen 20 can be cleaned. The utility model transports water to the nozzle 15 through the water pipe 13, the rotating sleeve 12, the rotating shaft 11 and the cross pipe 14, and finally sprays it from the nozzle 15, which effectively suppresses the lifting of cement powder. The cement powder is lifted during the operation of the well equipment. This spraying method wets the dust, promotes its sedimentation, avoids the discharge of dust into the atmosphere, protects the environment and the health of workers, and drives the rotating shaft 11 and the cross pipe 14 and the connected nozzle 15 to rotate through the mechanism of the worm 18 and the worm gear 17, so that the nozzle 15 can rotate dynamically when spraying water, increase the coverage of the water mist, and thus more effectively control the lifting of dust. The rotation of the rotating shaft 11 not only drives the nozzle 15, but also cleans the filter 20 through the brush plate 19 connected thereto. This automatic cleaning mechanism reduces the need for manual cleaning of the filter 20, extends the service life of the filter 20, and reduces maintenance time and cost.
