[0033] When in use, the atomizing nozzle 4 sprays dust removal liquid to wet collect the magnesite dust: the air guide plate 7 of the air inlet diffusion chamber 6 reduces the speed of the dust-containing airflow and uniformly disperses the airflow to prevent the dust-containing airflow from concentrating and breaking through the water curtain sprayed by the atomizing nozzle 4, which reduces the dust removal efficiency; the air guide frame 8 guides the rotating airflow into uniform parallel airflow, during which the large-particle impurities gather into the dust collection groove 5 below the air guide frame 8 due to their own gravity and are discharged through the corresponding drainage hole 13; the auxiliary inclination 9 guides the airflow to accurately flow below the atomizing nozzle 4 to prevent the atomizing nozzle 4 from being blocked; the dust is discharged with the liquid through the drainage hole 13 below the atomizing nozzle 4; finally, the dust removal subassembly 11 of the air outlet chamber 10 cooperates with the exhaust fan 12 to dry filter the residual dust, and the double dust removal ensures the purification effect; the detachable design of each component facilitates subsequent maintenance and replacement.

[0034] Please refer to Figure 2 The workbench 1 is fixedly installed with a motor fixing frame 14 and a lead screw adapter sleeve 15, the motor fixing frame 14 is fixedly installed with a driving motor 16, the driving end of the driving motor 16 is fixedly connected with a transmission lead screw 17 that is rotationally connected with the lead screw adapter sleeve 15, and the upper wall of the workbench 1 is also fixedly installed with two guide rails 18.

[0035] Please refer to Figure 3 The upper wall of the workbench 1 is provided with a support table 19, the lower wall of the support table 19 is fixedly installed with a threaded sleeve 20 that is engaged with the transmission lead screw 17, and the lower wall of the support table 19 is also fixedly installed with a guide seat 21 that is slidingly connected with the two guide rails 18.

[0036] In use, the motor fixing frame 14 stably fixes the driving motor 16, and the screw rod adapter sleeve 15 provides rotating support for the transmission screw rod 17; the driving motor 16 drives the transmission screw rod 17 to rotate, and drives the support table 19 to translate along the guide rail 18 (the guide seat 21 is matched with the guide rail 18 for accurate guidance) through the threaded sleeve 20, so that the position of the collecting device above the support table 19 can be adjusted to accurately dock with the drainage hole 13, and the convenience and accuracy of dust collection are improved.

[0037] Please refer to Figure 3 The upper wall surface of the support table 19 is fixedly installed with four hydraulic telescopic rods 22, and the telescopic ends of the four hydraulic telescopic rods 22 are fixedly installed with a bearing table 23.

[0038] In use, the hydraulic telescopic rods 22 are driven to extend or retract through a hydraulic working station, so that the height of the bearing table 23 can be flexibly adjusted to adapt to the height of the discharge port or the drainage hole 13, so that the collecting device is tightly fitted with the discharge position to avoid dust leakage; the four hydraulic telescopic rods 22 act synchronously to ensure that the bearing table 23 stably ascends and descends, and the structural stability is improved.

[0039] Please refer to Figure 3 The upper wall surface of the bearing table 23 is fixedly installed with two groups of positioning pins 24, two collecting boxes 25 are respectively inserted into the two groups of positioning pins 24, and the lower wall surfaces of the two collecting boxes 25 are both provided with pin holes 26 for insertion and cooperation with the two groups of positioning pins 24.

[0040] In use, the insertion and cooperation of the positioning pins 24 and the pin holes 26 realize the quick and accurate positioning of the collecting boxes 25 on the bearing table 23, so that the collecting boxes 25 are prevented from deviating when the equipment is running or the bearing table 23 is moving; meanwhile, the collecting boxes 25 are convenient to quickly disassemble and assemble, and can be directly pulled out and replaced when the dust is collected, so that the operation efficiency is improved.

[0041] Please refer to Figure 4 A structural rib plate 27 is fixedly installed between the workbench 1 and the support frame 2; in use, the structural rib plate 27 disperses the stress at the connection between the support frame 2 and the workbench 1 through a triangular stable structure, enhances the connection strength and overall rigidity of the two, avoids deformation of the equipment when the equipment is running for a long time or bears the weight of the collecting boxes 25, prolongs the service life of the equipment, and ensures stable dust removal operation.

[0042] Please refer to Figure 1 A safety chamfer 28 is formed at the edge of the workbench 1; in use, the safety chamfer 28 eliminates the sharp edges of the workbench 1, avoids scratches caused by bumps when the workers operate and maintain the equipment, improves the safety during use of the equipment, and adapts to the safety requirements of industrial operation scenes.

[0043] Please refer to Figure 4, the atomizing nozzles 4 are arranged in multiple groups in cross arrangement; in use, the atomizing nozzles 4 are arranged in multiple groups in cross arrangement, so that the sprayed dust-removing liquid forms a dense and uniform spraying coverage network, greatly increasing the contact area and contact probability of the dust-removing liquid and the dust-containing airflow, so that the magnesia dust is more fully captured, further strengthening the wet dust-removal effect and improving the overall dust-removal efficiency.

[0044] Please refer to Figure 4 , the dust-removal assembly 11 is composed of a cyclone plate, a mist eliminator and a fine filter screen; in use, the dust-removal assembly 11 is composed of a cyclone plate, a mist eliminator and a fine filter screen, further improving the dust purification precision.

[0045] In Example 1, through the multi-stage cooperation of speed reduction and dispersion by the air guide plates 7, precise guidance by the air guide frames 8, wet capture by the atomizing nozzles 4, preliminary interception by the dust collection grooves 5 and dry filtration by the dust-removal assembly 11, efficient purification of the magnesia dust is realized, and it is ensured that the exhaust gas meets the standards.

[0046] Specifically, after starting the equipment, the dust-containing airflow enters the air inlet diffusion chamber 6, the internal several evenly arranged air guide plates 7 uniformly disperse the airflow and simultaneously reduce the speed, avoiding concentrated airflow breaking through the water curtain. The dispersed airflow enters the dust-removal chamber 3 and is connected with the air guide holes of the air guide frames 8, the air guide frames 8 guide the airflow to form uniform parallel airflow, accurately flowing to the area below the dust collection grooves 5 and the atomizing nozzles 4, the auxiliary inclination angle 9 guides the airflow to accurately flow below the atomizing nozzles 4, preventing the atomizing nozzles 4 from being blocked. The atomizing nozzles 4 arranged in multiple groups in cross arrangement spray dust-removing liquid, forming a dense spraying network, fully contacting and capturing the fine dust in the airflow; large-particle impurities fall into the dust collection grooves 5 for preliminary interception due to their own gravity. The dust-removing liquid carrying dust and the impurities in the dust collection grooves 5 are discharged to the collection device through the corresponding drainage holes 13. Finally, the airflow treated by the wet method enters the air outlet chamber 10, and the dust-removal assembly 11 composed of a cyclone plate, a mist eliminator and a fine filter screen performs dry filtration, the residual dust is completely intercepted, the purified air is discharged under the action of the air outlet fan 12, realizing multi-stage dust removal of "speed reduction and dispersion-gravity interception-wet capture-dry filtration", and the dust removal efficiency is significantly improved.

[0047] In Example 2, through the transmission screw 17 driving translation and the hydraulic telescopic rod 22 adjusting height, the two collection boxes 25 are alternately connected to the drainage holes 13, reducing the downtime for replacing the collection boxes 25 and ensuring continuous operation of the equipment.

[0048] Specifically, in the initial state, the two collecting boxes 25 are respectively inserted into the two groups of positioning pins 24 of the load-bearing table 23 through the pin holes 26 in the lower wall, and precise positioning is completed. The driving motor 16 is started, and the driving end drives the transmission screw rod 17 to rotate in the screw rod adapter sleeve 15. The transmission screw rod 17 is engaged with the threaded sleeve 20 in the lower wall of the support table 19, drives the support table 19 to translate along the two guide rails 18 through the guide seat 21, and simultaneously starts the four hydraulic telescopic rods 22 to extend and retract, adjusts the height of the load-bearing table 23, makes the first collecting box 25 precisely dock with the plurality of drainage holes 13 in the lower wall of the dust removal chamber 3, and collects dust and dust removal liquid. When the first collecting box 25 is full, the driving motor 16 drives the support table 19 to translate, and the hydraulic telescopic rod 22 is finely adjusted in height, so that the second collecting box 25 is quickly docked with the drainage hole 13, and the collection operation continues; at this time, the staff can directly pull out the full collecting box 25 to replace the empty box, and quickly reset through the positioning pin 24 and the pin hole 26. Through the process of "translation switching-height adaptation-alternate collection", the downtime for replacing the box is greatly reduced, and the continuous operation efficiency of the equipment is improved.

[0049] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
