Description

Technical Field

[0001] The invention relates to the field of filtration and separation, and in particular to a gold mine tailings dehydration device. Background Art

[0002] Gold tailings are the product of sorting operations during gold mining and beneficiation. Due to their low gold content, they cannot be used for conventional processing and production. The initially discharged gold tailings are usually wet and contain a large amount of slurry. If they are discharged directly, they are likely to cause environmental pollution. Therefore, in the prior art, a dehydration device is usually used to dehydrate the gold tailings.

[0003] In the prior art, when dehydrating gold mine tailings, the slurry in the tailings is usually pre-screened out, and then the slurry is subjected to filter pressure treatment to finally obtain relatively dry large-particle ore and residue. During the filter pressure process, the filter used in the filter pressure has high filtration accuracy and is inconvenient to replace under normal circumstances. This leads to the dehydration effect of the filter pressure dehydration gradually weakening after the dehydration device repeatedly filters the slurry, and it is usually necessary to stop the machine to clean the filter, which can easily affect the dehydration efficiency of the gold mine tailings.

The filter mechanism 4 includes a plurality of second rollers 401 longitudinally rotatably installed at the corner positions of the dehydration bin 3, the outer sides of the plurality of second rollers 401 are jointly driven and sleeved with an annular filter belt 402, a pressing plate 403 is movably installed in the dehydration bin 3, and the pressing plate 403 is fixedly connected to the moving end of the electric slide rail 302, a plurality of continuously connected V-shaped hinged plates 404 are arranged in the dehydration bin 3, and the V-shaped hinged plates 404 include two plate bodies 4041 symmetrically arranged on the left and right, a through window 4042 is horizontally opened in the plate body 4041, and a through slot 4042 is vertically opened in the plate body 4041. 43, a connecting piece 4044 is hinged between the bottom ends of the two plate bodies 4041, a first slider 405 is hinged between the top ends of the two adjacent V-shaped hinged plates 404, and the first slider 405 is slidably installed in the slide groove 301, the top end of the plate body 4041 closest to the pressing plate 403 is hinged to the pressing plate 403, and the top end of the plate body 4041 farthest from the pressing plate 403 is hinged to the inner end wall of the dehydration bin 3, and the annular filter belt 402 is movably inserted in the through slots 4043 in the numerous plate bodies 4041 in turn, forming a corrugated structure that fluctuates up and down, and a second filter belt 402 is arranged above the screening conveyor belt 102. A spray box 5 is provided, and the bottom end wall of the second spray box 5 is provided with evenly distributed spray holes. The screening conveyor belt 102 includes a conveyor frame 1021, and three first rollers 1022 are rotatably installed in the conveyor frame 1021. The outer sides of the three first rollers 1022 are commonly transmission-sleeved with an annular screen belt 1023, and the outer surface of the annular screen belt 1023 is fixedly provided with a plurality of evenly distributed baffles 1024. A transmission mechanism 105 is transmission-connected between the electric conveyor belt 101 and the plurality of screening conveyor belts 102, and the electric conveyor belt 101 and the plurality of screening conveyor belts 102 share a driving unit.

[0048] When the device is actually used, the staff connects the device to an external power supply through a wire, so that the external power supply provides power support for the device. A driving unit is provided on the electric conveyor belt 101, and the driving unit drives the transmission belt in the electric conveyor belt 101 to rotate, so as to realize the transportation of gold tailings. After the driving unit is started, the first rollers 1022 in the numerous screening conveyor belts 102 are driven to rotate synchronously with the transmission belt in the electric conveyor belt 101 with the help of the transmission connection of the transmission mechanism 105. During the rotation of the first roller 1022, the annular screen belt 1023 sleeved on its outer side can be driven to rotate synchronously, thereby driving the numerous baffles 1024 whose outer surfaces are uniformly fixed to move, and the baffles 1024 are vertically arranged to the outer surface of the annular screen belt 1023. This makes the gold tailings be transported to the right on the baffles 102. 024, it moves stably upward or downward on the annular screen belt 1023. With the help of the second receiving bucket 104 set between two adjacent screening conveyor belts 102, the stability of the gold tailings moving between the numerous screening conveyor belts 102 can be guaranteed. The second spray box 5 is externally connected to a medicine solution supply device, and the prepared medicine is provided to the second spray box 5 through the medicine solution supply device. In the process of the gold tailings being transported on the annular screen belt 1023, the medicine is sprayed downward from the second spray box 5 to the gold tailings on the annular screen belt 1023, which can dissolve the remaining metals in the gold tailings. The solution containing the metals in the gold tailings and the slurry in the gold tailings pass through the through holes on the annular screen belt 1023 downward into the temporary storage bin 2, and other large particles of ore particles remain on the annular screen belt 1023 and are finally discharged outward through the first receiving bucket 103.

[0049] In each screening conveyor belt 102, the distance between the upper and lower first rollers 1022 is much larger than the distance between the left and right first rollers 1022, which enables the screening conveyor belt 102 to perform long-distance upward inclined conveying and long-distance downward inclined conveying when screening and conveying the gold tailings, thereby extending the actual length of the gold tailings being transported as much as possible in terms of height space, and can effectively reduce the lateral space occupied by many screening conveyor belts 102, which is conducive to reducing the actual occupied space of the device and facilitating its use convenience. A vibration motor is fixedly installed on the screening conveyor belt 102, and the vibration motor is used to provide high-intensity vibration and shaking for the gold tailings passing on the screening conveyor belt 102, thereby facilitating the improvement of the efficiency and comprehensiveness of the downward falling of the solution containing dissolved metals and the slurry in the gold tailings.

[0050] The solution containing dissolved metals and the slurry substance in the gold tailings are collectively referred to as a mixture. The multiple screening conveyor belts 102 are divided into two parts, left and right, from the middle. The second spray box 5 is arranged above the multiple screening conveyor belts 102 on the left, and the multiple screening conveyor belts 102 on the right are not equipped with the second spray box 5. This allows the gold tailings to be sprayed with medicine only on the left side when being transported on the screening conveyor belt 102, and when being transported by the screening conveyor belt 102 on the right, in conjunction with the start-up of the vibration motor on the screening conveyor belt 102, a small amount of the mixture remaining in the large-particle ore in the gold tailings can be shaken off into the temporary storage bin 2, thereby realizing the dehydration operation of the large-particle ore.

[0051] The mixture falls downward into the dehydration bin 3 through the temporary storage bin 2, and finally falls into the multiple unfolded V-shaped hinged plates 404, and is caught by the annular filter belt 402. The outer size of the plate body 4041 is adapted to the inner size of the dehydration bin 3. When the mixture on the annular filter belt 402 in the V-shaped hinged plate 404 accumulates to a sufficient amount, the electric slide rail 302 installed in the slide groove 301 is powered on and started, driving the pressing plate 403 connected to its moving end to move. With the help of the push formed by the movement of the pressing plate 403, the multiple unfolded V-shaped hinged plates 404 are squeezed from one side, so that the multiple V-shaped hinged plates 404 are compressed. At this time, the mixture loaded on the annular filter belt 402 in the V-shaped hinged plate 404 is squeezed, and the solution containing metal dissolved in the mixture is The water in the slurry material in the gold mine tailings passes through the annular filter belt 402 and is squeezed out, and the residue remains on the annular filter belt 402 inside the V-shaped hinged plate 404, thereby realizing the dehydration operation of the residue. A receiving box is fixedly installed in the dehydration bin 3, which is arranged in the annular filter belt 402 and below many V-shaped hinged plates 404. The squeezed solution falls into the receiving box and is then discharged, and is finally collected by the staff for separate treatment. An openable movable door is provided on the back of the dehydration bin 3. When the mixture is dehydrated, the electric slide rail 302 controls the pressure plate 403 to move in the opposite direction and reset, so that many pressure plates 403 are reset from a compressed state to an expanded state. At this time, the staff can open the movable door to clean the residue on the annular filter belt 402 inside the V-shaped hinged plate 404.

[0052] A driving unit is fixedly installed on the outside of the dehydration bin 3, and the driving unit is connected to one of the second rollers 401. When a batch of mixtures is dehydrated and a plurality of V-shaped hinged plates 404 are in an unfolded state, the driving unit can drive the second roller 401 to rotate, thereby driving the annular filter belt 402 connected to the outside of the roller to rotate. As the annular filter belt 402 rotates, the annular filter belt 402 that was previously in the through-slot 4043 is rotated out, and the annular filter belt 402 that was not previously in the through-slot 4043 is rotated into the through-slot 4043, thereby realizing the corresponding annular filter belt 402 in the V-shaped hinged plate 404. The annular filter belt 402 is replaced to ensure that the mixture on the annular filter belt 402 in the numerous V-shaped hinged plates 404 is stably and efficiently filtered and dehydrated by the annular filter belt 402, and a previously used section of the annular filter belt 402 is exported by rotation and is in an unused state. At this time, the staff can clean it, and the cleaning operation is independent of the use of the annular filter belt 402 to filter and dehydrate the mixture, and the two do not interfere with each other, so that the filter press mechanism 4 can continuously and stably dehydrate the mixture. Compared with the technical solution in the prior art that the annular filter belt 402 cannot be moved and replaced, the present application can effectively improve the efficiency of gold mine tailings dehydration.

[0053] In the specific implementation process, Figure 4 , Fig. 9 and Fig.15 As shown, a hollow box 201 is fixedly installed at the bottom of the temporary storage bin 2, and a plurality of first through holes 202 penetrating from top to bottom are evenly distributed on the hollow box 201, a valve plate 203 is slidably inserted in the hollow box 201, and second through holes 204 corresponding to the plurality of first through holes 202 are evenly distributed on the valve plate 203, the hollow box 201 protrudes at the front and rear sides of the temporary storage bin 2, a gear rod 205 arranged on the outside of the temporary storage bin 2 is fixedly installed on the top of the valve plate 203, and a gear 206 meshing with the gear rod 205 is rotatably installed on the outside of the temporary storage bin 2.

[0054] When the device is actually used, the mixture falling downward from the annular screen belt 1023 will first enter the temporary storage bin 2. Under normal circumstances, the second through hole 204 on the valve plate 203 is vertically connected with the first through hole 202 on the hollow box 201. At this time, the mixture in the temporary storage bin 2 will fall downward into the dehydration bin 3 through the connected first through hole 202 and second through hole 204, and finally enter the annular filter belt 402 inside the V-shaped hinged plate 404. A driving unit is also installed on the outer side of the temporary storage bin 2, and the driving unit is connected to the gear 206. When a sufficient amount of mixture enters the annular filter belt 402 inside the V-shaped hinged plate 404, the staff can control the driving unit to drive the gear 206 to rotate, and the gear 206 and the gear rod 205 are meshed with each other. The valve plate 203 is closed to drive the valve plate 203 to move in the hollow box 201. The movement of the valve plate 203 causes the second through hole 204 and the first through hole 202 to be misaligned and no longer connected. At this time, the mixture can be temporarily stored in the temporary storage bin 2, and after the mixture is pressed and dehydrated on the annular filter belt 402 in the V-shaped hinged plate 404 and the residue is cleaned out, the second through hole 204 and the first through hole 202 can be controlled to be connected again to perform the dehydration operation of the next batch of mixture. The movement of the valve plate 203 controls the connection and closure of the second through hole 204 and the first through hole 202, so that a large amount of mixture can be temporarily stored in the temporary storage bin 2 and lowered in batches according to actual work needs, which can improve the flexibility and orderliness of the device in actual use to a certain extent.

[0055] In the specific implementation process, Fig.11 and Fig.14As shown, a second slider 406 is vertically slidably installed in the dehydration bin 3, and a longitudinally arranged traction roller 407 is rotatably installed in the second slider 406, and the annular filter belt 402 is movably wound around the outside of the traction roller 407, and a tension spring 408 fixedly connected to the top end wall of the dehydration bin 3 is fixedly installed on the second slider 406, and a third roller 409 symmetrically arranged on both sides of the traction roller 407 is longitudinally rotatably installed in the dehydration bin 3, and the third roller 409 is rotatably installed at the bottom of the dehydration bin 3, and a first spray box 410 arranged on the inner side of the annular filter belt 402 is fixedly installed on the inner end wall of the dehydration bin 3, and the end wall of the first spray box 410 facing the annular filter belt 402 is provided with evenly distributed spray holes. When the device is actually used, the second slider 406 is stably in a position under the elastic connection of the tension spring 408. In the dehydration bin 3, under the guidance of the two third rollers 409 at the bottom, the annular filter belt 402 can be stably wound around the upper outer side of the traction roller 407. When the V-shaped hinge plate 404 is in the expanded state, the annular filter belt 402 is in a relatively dispersed state. At this time, the traction on the traction roller 407 is weak, and the traction roller 407 is stably in the upper position in the dehydration bin 3. When the V-shaped hinge plate 404 is in a compressed state, the section of the annular filter belt 402 inserted in the slot 4043 is in a relatively concentrated state. At this time, the traction on the traction roller 407 is strong, and the traction roller 407 will be pulled downward to release the annular filter belt 402 collected here. Under the elastic connection of the tension spring 408, the movement of the annular filter belt 402 is supplemented, which is beneficial to ensure the stability of the device during actual operation.

[0056] The first spray box 410 is externally connected to a cleaning water supply device. When the annular filter belt 402 needs to be cleaned, the cleaning water is sprayed from the inner side of the annular filter belt 402 onto the annular filter belt 402 through the spray holes opened on the first spray box 410, thereby realizing backwash cleaning of the annular filter belt 402. The sewage generated by the flushing is collected at the bottom of the dehydration bin 3 and can be reused after being discharged and filtered.

[0057] In the specific implementation process, Fig.10 , Fig.11 and Fig.14As shown, a first partition 6 is vertically fixed at the middle position of the temporary storage bin 2, and a second partition 601 is vertically fixed at the middle position of the dehydration bin 3. The first partition 6 and the second partition 601 divide the temporary storage bin 2 and the dehydration bin 3 into two left and right parts respectively, and are arranged corresponding to the multiple screening conveyor belts 102 on the left and right sides. There are two filter press mechanisms 4, which are symmetrically arranged in the left and right parts of the dehydration bin 3. When the device is actually used, since the second spray box 5 is arranged on the left side, it is directly sprayed with the medicine, making the mixture falling on the multiple screening conveyor belts 102 on the left side turbid and complex, and since the second spray box 5 covers the right There are multiple screening conveyor belts 102 on the side, which makes the composition of the mixture falling on the multiple screening conveyor belts 102 on the right side relatively simple, and the amount of slurry contained in the mixed liquid falling on the left side is much larger than the slurry in the mixed liquid falling on the right side. By dividing the temporary storage bin 2 and the dehydration bin 3 into two parts, the left part of the temporary storage bin 2 and the dehydration bin 3 corresponds to the left screening conveyor belt 102, and the right part of the temporary storage bin 2 and the dehydration bin 3 corresponds to the right screening conveyor belt 102. The mixture in the left and right parts is dehydrated by separate filter pressing mechanisms 4, which is beneficial to carry out targeted treatment according to the actual state of the mixture, making the dehydration process more refined.

[0058] Specifically, the working principle and operation method of the present invention are as follows:

[0059] The staff continuously introduces the gold tailings through the electric conveyor belt 101. Under the connection of many second receiving buckets 104, the gold tailings move from left to right on many screening conveyor belts 102. The medicine is sprayed downward onto the gold tailings through the second spray box 5. Through the dissolution and flushing of the medicine, the slurry and metal in the gold tailings form a mixture, which passes through the annular screen belt 1023 and goes downward into the temporary storage bin 2. The remaining large particles of ore continue to be transported to the right and are led out through the first receiving bucket 103. By starting the vibration motor on the screening conveyor belt 102, the falling efficiency of the mixture is accelerated, and the moisture in the large particles of ore on the right screening conveyor belt 102 can be greatly shaken off. Then, with the meshing of the toothed rod 205 and the gear 206, the control valve plate 203 is horizontally moved in the hollow box 201 through the rotation of the gear 206. The first through hole 202 and the second through hole 204 are moved to realize the on-off control of the first through hole 202 and the second through hole 204. When the first through hole 202 and the second through hole 204 are connected, the mixture in the temporary storage bin 2 flows downward into the dehydration bin 3, and finally accumulates on the annular filter belt 402 inside the V-shaped hinged plate 404. Subsequently, under the start of the electric slide rail 302, the pressure plate 403 is controlled to move, and a squeeze is applied to the many unfolded V-shaped hinged plates 404, so that the V-shaped hinged plates 404 are compressed, and the dehydration operation of the mixture is realized by high-intensity squeezing. After dehydration is completed, the annular filter belt 402 is unfolded again, and the residue remaining on the annular filter belt 402 inside the V-shaped hinged plate 404 is cleaned, and the annular filter belt 402 is driven to rotate and move to replace the filtering position. Synchronously, the clean water sprayed from the first spray box 410 is used to realize the backwash cleaning of the annular filter belt 402.
