EMBODIMENT

[0040] As Figures 1-7 shown in the technical solution, the present application provides the following technical solution: in order to solve the problem of low purification efficiency of the flue gas purification device and the problem of more harmful substances remaining, a spraying mechanism is disclosed:

[0041] The utility model provides an improve smoke gas purifying device efficiency's spraying mechanism, first spout board 114 bottom is equipped with the rotation groove 122, and the rotation groove 122 is equipped with four, and the rotation groove 122 is equipped with the adjusting mechanism of improving the spraying range of spraying device, and the first spout board 114 center is installed electric push rod, and the electric push rod output portion is fixed with push plate 125, and push plate 125 passes through movablely connected first spout board 114 bottom, and the first spout board 114 bottom is equipped with the rotation mechanism of adjusting the flow of spraying mechanism, and the spraying mechanism includes disc block 106, and disc block 106 is fixed in second rotary rod 105 one end, and disc block 106 is fixed with eccentric block in the side away from second rotary rod 105, and eccentric block surface passes through the sliding extrusion block 107, and extrusion block 107 is fixed with sliding frame 108 in the end close to the utility model body, and sliding frame 108 passes through sliding in the utility model body with first spout board 114 inside, and sliding frame 108 is connected with the sealing ring between the utility model body, and second rotary rod 105 other end is fixed with second transmission wheel 109, and second transmission wheel 109 is transmissionally connected with first transmission wheel 103 between transmission belt 110, and the upper surface of external connection platform 101 close to electric motor output portion is installed with vane pump 111, and the vane rod in vane pump 111 is fixed in the end of first rotary rod 102, and the water outlet of vane pump 111 is connected with first connecting pipe 112, and the water inlet of vane pump 111 is connected with second connecting pipe 113, and second connecting pipe 113 is connected in the utility model body inside, and the utility model body is installed with second spout board 115 in the inside close to first spout board 114, and second spout board 115 is connected with second spray head 117 and first spray head 116 respectively in the bottom of first spout board 114, and first spray head 116 and second spray head 117 are all connected with multiple groups, and the utility model body is fixed with two connecting plates 119 in the inside, and the utility model body is S-shaped cavity through connecting plate 119 in the inside, and the utility model body is stored with purified water in the bottom surface, and the utility model body is installed with filter 120 in the inside, and filter 120 is covered in the water inlet end surface of second connecting pipe 113, and filter 120 surface movablely connected with cleaning brush ring 121, and cleaning brush ring 121 top is fixed with sliding block 118, and sliding block 118 is fixed in the bottom close to first spout board 114 of sliding frame 108, and sliding block 118 is slid in the utility model body inside through plug block in the inside,

[0042] When the purification device is in use, under the action of the air pump, the flue gas generated by copper smelting will flow to the inside of the purification device along the pipeline, and after the harmful substances in the flue gas are eliminated through the spraying system and the filtering system, the flue gas will be discharged into the air. When the flue gas passes through the spraying system, it can enter through the smoke inlet 2, and then be discharged to the next procedure through the smoke outlet 3 after passing through the device main body 1. When the flue gas passes through the inside of the device main body 1, due to the special placement of the two connecting plates 119, the flue gas will flow in an S shape, and the fixed particles will directly fall into the purification water inside the device main body 1 when turning, achieving flue gas treatment. At the same time, the output end of the starting motor can drive the first rotating rod 102 to rotate, and when the first rotating rod 102 rotates, it can drive the impeller rod inside the impeller pump 111 to rotate. When the impeller rotates, it can extract the purification water inside the device main body 1 through air pressure. The water can flow into the first connecting pipe 112 through the second connecting pipe 113 for shunting. After the water in the first connecting pipe 112 is shunted, it can be discharged into the first spray plate 114 and the second spray plate 115 respectively. The first spray plate 114 and the second spray plate 115 can further shunt the water through their own structure. The shunted water can be sprayed through multiple groups of first spray heads 116 and second spray heads 117. The spraying can effectively remove harmful substances in the flue gas. Since the flue gas is in an S shape, multiple spraying effects can be achieved. At the same time of spraying, the rotation of the first rotating rod 102 can drive the first transmission wheel 103 to rotate, and the first transmission wheel 103 can drive the second transmission wheel 109 to rotate through the transmission belt 110. The second transmission wheel 109 can drive the second rotating rod 105 to rotate, and the second rotating rod 105 can rotate through the first fixed block 104. The second rotating rod 105 can drive the disc block 106 to rotate, and the disc block 106 can drive the eccentric block to rotate. The eccentric block can extrude the inner wall of the extrusion block 107 when rotating. The extrusion block 107 can drive the sliding frame 108 to move when being extruded. The sliding frame 108 can slide through the device main body 1 when moving. Since the eccentric block rotates through the center of the disc block 106, the sliding frame 108 can make reciprocating motion. The sliding frame 108 can drive the sliding block 118 at the bottom to move when reciprocating. The sliding block 118 can slide through the insertion block when moving. The sliding block 118 can drive the cleaning brush ring 121 to move when sliding. The cleaning brush ring 121 can reciprocate on the surface of the filter 120 when moving. The cleaning brush ring 121 can clean the surface of the filter 120 when reciprocating, preventing the filter 120 from being blocked and affecting the spraying effect of the purification device, and improving the spraying effect of the spraying system of the purification device. Embodiment

[0043] As Figure 8 and Figure 9The present invention provides the following technical solution to address the problem that the spraying range of the purification device's spraying mechanism is not wide and the spraying effect may be insufficient. Based on Embodiment 1, an adjustment mechanism is disclosed:

[0044] The adjusting mechanism includes a semi-toothed block 123, which rotates inside the rotating groove 122. The semi-toothed block 123 is meshed with the sliding frame 108. A second fixing block 124 is fixed to the bottom of the semi-toothed block 123, and a first spray head 116 is connected to the bottom of the second fixing block 124. The semi-toothed block 123 is fixed to the bottom of the rotating groove 122. When the spraying mechanism of the purification device is in use, the sliding frame 108 can reciprocate under the action of the disc block 106. When the sliding frame 108 moves, it can slide through the first spray plate 114. When the sliding frame 108 slides, the teeth at the bottom can drive the half-tooth block 123 to engage and rotate. When the half-tooth block 123 engages and rotates, it can rotate through the rotating groove 122. When the half-tooth block 123 rotates, it can drive the second fixed block 124 to rotate. When the second fixed block 124 rotates, it can drive the first nozzle 116 to rotate. When the first nozzle 116 rotates, it can change the spray direction, increase the spray range of the purification device's spray mechanism, make the liquid contact the flue gas more effectively, and enhance the purification effect of the purification device's spray system. Example

[0045] like Figure 8 , Figure 10 , Figure 11 and Figure 12 The present invention provides the following technical solution to address the problem that the water spray volume of the flue gas purification device is inconvenient to adjust, easily leading to waste and increased operating costs: A rotating mechanism is disclosed.

[0046] The rotating mechanism includes a fixed rod 126, which is symmetrically fixed to the bottom of the push plate 125. A guide rod 127 is fixed to the bottom of the fixed rod 126. Multiple sets of guide rods 127 are fixed. The guide rods 127 slide through the inside of the first nozzle 116. A fixed ring 128 is fixed to the bottom of the guide rod 127. The fixed ring 128 is movably connected to the inside of the first nozzle 116. A water spray pipe is connected through the inside of the first nozzle 116. A rotating block 129 is rotatably connected to the inside of the first nozzle 116 near the fixed ring 128. Five sets of rotating blocks 129 are provided. An arc-shaped block 130 is fixed to the bottom of the rotating block 129. A sliding groove 131 is opened on the back of the rotating block 129. A slider 132 slides inside the sliding groove 131. A rotating rod 133 is rotatably connected to the side of the slider 132 away from the rotating block 129. The rotating rod 133 is fixed inside the fixed ring 128.

[0047] During the flue gas spraying process of the purification device, activating the electric actuator can move the push plate 125. The movement of the push plate 125 can move two symmetrical sets of fixed rods 126. The movement of the fixed rods 126 can move the guide rods 127. The guide rods 127 can slide through the first nozzle 116. The sliding of the guide rods 127 can move the fixed ring 128. The sliding of the fixed ring 128 can move multiple sets of rotating rods 133. The movement of the rotating rods 133 can move the slider 132. The slider 132 can slide through the sliding groove 131. Simultaneously, the movement of the slider 132 can... The sliding groove 131 is compressed, which drives the rotating block 129 to rotate. The rotation of the rotating block 129 causes the first nozzle 116 to rotate. Simultaneously, the rotation of the rotating block 129 also drives the arc-shaped block 130 to rotate. The rotation of the arc-shaped block 130 compresses the water spray pipe inside the first nozzle 116, changing its size. This compression allows for adjustment of the spray flow rate, enabling the purification device to use different spray volumes based on the flue gas concentration. This reduces resource and power consumption waste and improves the ease of use of the flue gas purification device.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
