Description

Technical Field

[0001] The invention relates to the technical field of copper smelting, and in particular to a copper smelting fume purification device with a high purification rate. Background Art

[0002] Copper smelting is the process of extracting copper from copper ore and purifying it into metallic copper. Copper smelting will produce harmful flue gas, which requires the use of flue gas purification equipment. This equipment is used to reduce harmful components in flue gas and protect the environment. At present, there may be room for improvement in the efficiency of flue gas treatment by purification equipment. Purification equipment is an indispensable part of industrial production.

[0003] At present, there are still some deficiencies in the flue gas purification device. For example, the ordinary flue gas washing device cannot clean the flue gas:

[0004] In order to overcome the problem of incomplete flue gas cleaning, a Chinese patent of the prior art (publication number: CN214552066U) discloses a copper smelting complex flue gas washing and purification device, which circulates the washing liquid through a longitudinal circulation pump and a transverse circulation pump, which not only further optimizes the flue gas impurity removal effect, but also improves the use efficiency of the impurity removal agent and reduces the production cost;

[0005] In addition, a Chinese patent of the prior art (publication number: CN216321061U) discloses a copper smelting flue gas treatment device, which separates dust and debris in the flue gas and precipitates produced in the reaction from the liquid through a filter screen. The filtered liquid enters a circulating water tank through a connecting pipe for recycling, and the debris and precipitates enter a sedimentation tank through a sewage pipe. The filter screen can be taken out from the inside of the connecting pipe, which is convenient for cleaning and replacement, thereby improving the practicality of the device.

[0006] However, the flue gas purification devices currently used still have certain shortcomings. In the above-mentioned documents, the flue gas is treated through multi-layer purification, including spraying system, adsorption system, desulfurization and other steps.

An electric push rod is installed inside the center of the first spray plate 114, and a push plate 125 is fixed to the output end of the electric push rod. The push plate 125 is movably connected to the bottom of the first spray plate 114. A rotating mechanism for adjusting the spray flow rate of the spray mechanism is arranged at the bottom of the first spray plate 114. The spray mechanism includes a disc block 106, and the disc block 106 is fixed to one end of the second rotating rod 105. An eccentric block is fixed to the side of the disc block 106 away from the second rotating rod 105. An extrusion block 107 slides through the surface of the eccentric block, and a sliding frame 108 is fixed to the end of the extrusion block 107 close to the device body 1. The sliding frame 108 slides through the device body 1 and Inside the first jet plate 114, a sealing ring is connected between the sliding frame 108 and the device body 1, a second transmission wheel 109 is fixed to the other end of the second rotating rod 105, and a transmission belt 110 is connected between the second transmission wheel 109 and the first transmission wheel 103, an impeller pump 111 is installed on the upper surface of the external platform 101 near the output end of the motor, the impeller rod inside the impeller pump 111 is fixed to the end of the first rotating rod 102, the water outlet of the impeller pump 111 is connected to the first connecting pipe 112, the water inlet of the impeller pump 111 is connected to the second connecting pipe 113, the second connecting pipe 113 is connected to the inside of the device body 1, and a second jet plate 115 is installed inside the device body 1 near the first jet plate 114, and the second jet plate 115 and The bottom of the first spray plate 114 is respectively connected to the second spray head 117 and the first spray head 116, and the first spray head 116 and the second spray head 117 are both connected to multiple groups. Two connecting plates 119 are fixed inside the device body 1. The inside of the device body 1 is an S-shaped cavity through the connecting plates 119. Purified water is stored on the bottom surface of the inside of the device body 1. A filter 120 is installed inside the device body 1. The filter 120 is sleeved on the surface of the water inlet end of the second connecting pipe 113. A cleaning brush ring 121 is movably connected to the surface of the filter 120. A sliding block 118 is fixed on the top of the cleaning brush ring 121. The sliding block 118 is fixed to the bottom of the sliding frame 108 close to the first spray plate 114, and the inside of the sliding block 118 slides inside the device body 1 through an insert block.

[0043] When the purification device is in use, under the action of the air pump, the flue gas generated by copper smelting will flow along the pipeline to the inside of the purification device, and will be discharged into the air after the harmful substances in the flue gas are eliminated through the spray system and the filtering system and other procedures. The flue gas can enter through the smoke inlet 2 after passing through the spray system, and then be discharged to the next procedure through the smoke outlet 3 after passing through the smoke inlet 2 and the device body 1. When the flue gas passes through the inside of the device body 1, due to the special arrangement of the two connecting plates 119, the flue gas will flow in an S shape, and when turning, the fixed particles will directly fall into the purified water inside the device body 1, thereby realizing the flue gas treatment. At the same time, the output end of the starting motor can drive the first rotating rod 102 to rotate When the first rotating rod 102 rotates, the impeller rod inside the impeller pump 111 can be driven to rotate. When the impeller rotates, the purified water inside the device body 1 can be extracted by air pressure. The water can flow into the first connecting pipe 112 through the second connecting pipe 113 for diversion. After the water in the first connecting pipe 112 is diverted, 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 divert the water again through their own structures. The diverted water can be sprayed through multiple groups of first nozzles 116 and second nozzles 117. When spraying, harmful substances in the smoke can be effectively removed. Since the smoke is in an S-shaped direction , a multiple spraying effect can be achieved. When the purification device sprays, the rotation of the first rotating rod 102 can drive the first transmission wheel 103 to rotate. When the first transmission wheel 103 rotates, it can drive the second transmission wheel 109 to rotate through the transmission belt 110. When the second transmission wheel 109 rotates, it can drive the second rotating rod 105 to rotate. When the second rotating rod 105 rotates, it can rotate through the first fixed block 104. When the second rotating rod 105 rotates, it can drive the disc block 106 to rotate. When the disc block 106 rotates, it can drive the eccentric block to rotate. When the eccentric block rotates, it can squeeze the inner wall of the squeezing block 107. When the squeezing block 107 is squeezed, it can drive the sliding frame 108 to move When the sliding frame 108 moves, it can slide through the device body 1. Since the eccentric block rotates through the center of the disc block 106, the sliding frame 108 can reciprocate. When the sliding frame 108 reciprocates, it can drive the sliding block 118 at the bottom to move. When the sliding block 118 moves, it can slide through the insert block. When the sliding block 118 slides, it can drive the cleaning brush ring 121 to move. When the cleaning brush ring 121 moves, it can reciprocate on the surface of the filter 120. When the cleaning brush ring 121 reciprocates, the surface of the filter 120 can be cleaned, thereby preventing the filter 120 from being blocked and affecting the spraying effect of the purification device, thereby improving the spraying effect of the spray system of the purification device.

[0044] Embodiment 2:

[0045] like Figure 8 and Fig. 9The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the spraying range of the spraying mechanism of the purification device is not wide and the spraying effect may be insufficient, on the basis of the first embodiment, an adjustment mechanism is disclosed:

[0046] The adjustment mechanism includes a half-tooth block 123, which rotates inside the rotating groove 122. The half-tooth block 123 is meshed with the sliding frame 108. A second fixed block 124 is fixed to the bottom of the half-tooth block 123, and a first nozzle 116 is connected to the bottom of the second fixed block 124. The half-tooth block 123 is fixed to the bottom of the rotating groove 122. When the spray mechanism of the purification device is used, 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 direction of spraying, thereby increasing the spraying range of the spraying mechanism of the purification device, allowing the liquid to contact the flue gas more effectively, and enhancing the purification effect of the spraying system of the purification device.

[0047] Embodiment three:

[0048] like Figure 8 , Fig.10 , Fig.11 and Fig.12 The technical solution shown in the figure, the present invention provides the following technical solution: In order to solve the problem that the water spraying amount of the flue gas purification device is inconvenient to adjust, which easily causes waste and increases the use cost, a rotating mechanism is disclosed:

[0049] The rotating mechanism includes a fixed rod 126, which is symmetrically fixed at the bottom of the push plate 125. A guide rod 127 is fixed at the bottom of the fixed rod 126. There are multiple groups of guide rods 127 fixed. The guide rod 127 penetrates and slides inside the first nozzle 116. A fixed ring 128 is fixed at 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 to 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. The rotating block 129 is provided with five groups. An arc block 130 is fixed to the bottom end of the rotating block 129. A sliding groove 131 is provided 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 to the inner side of the fixed ring 128.

[0050] During the process of the purification device spraying the flue gas, the electric push rod is started to push the push plate 125 to move. When the push plate 125 moves, it can drive the two symmetrical groups of fixed rods 126 to move. When the fixed rod 126 moves, it can drive the guide rod 127 to move. When the guide rod 127 moves, it can slide through the first nozzle 116. When the guide rod 127 slides, it can drive the fixed ring 128 to slide. When the fixed ring 128 slides, it can drive multiple groups of rotating rods 133 to move. When the rotating rod 133 moves, it can drive the slider 132 to move. When the slider 132 moves, it can slide through the sliding groove 131. At the same time, the slider 132 can move. The sliding groove 131 is squeezed, and when the sliding groove 131 is squeezed, the rotating block 129 can be driven to rotate, and when the rotating block 129 is rotated, the first nozzle 116 can be rotated, and the rotating block 129 can simultaneously drive the arc block 130 to rotate, and when the arc block 130 is rotated, the water spray pipe inside the first nozzle 116 can be squeezed, and the water spray pipe can change its size when squeezed. By squeezing the water spray pipe, the spray flow rate can be adjusted, so that the purification device can use different spraying amounts according to the smoke concentration, thereby reducing the waste of resources and power consumption of the purification device and improving the convenience of using the smoke purification device.
