Description

Technical Field

[0001] The present invention belongs to the technical field of filtration treatment, and particularly relates to a gold mine tailings dehydration device. Background Art

[0002] Tailings dehydration is to remove the moisture in tailings through physical or chemical methods, separate solid particles from liquid, thereby reducing the volume of tailings and improving the efficiency of subsequent treatment. Its main principles include: Gravity sedimentation: Using the action of gravity to make the solid particles in tailings settle and separate the clear water on the upper layer.

[0003] Centrifugal separation: Through the centrifugal force generated by high-speed rotation, separate solid particles from liquid.

[0004] Filtration: Using the pores of filter cloth or filter screen to intercept solid particles and discharge water through the pores.

[0005] Pressure dehydration: By applying external pressure, squeeze out the water from tailings.

[0006] In the gold ore beneficiation process, the dehydration treatment of tailings is a key link to reduce the capacity of tailing ponds, reduce the risk of environmental pollution, and achieve comprehensive utilization of resources. At present, for the dehydration operation of some gold mine tailings, there is a solution in the prior art that uses a filter plate pressing method for treatment. The specific operation of this solution is: lay the tailings to be dehydrated on the filter plate, and then use a pressing plate to physically press the filter plate and the tailings thereon to forcibly discharge the water therein.

[0007] However, this dehydration method based on filter plate pressing has significant limitations. First of all, its operation process is discontinuous. Before each pressing dehydration operation, it is necessary to stop adding tailings; and after the pressing dehydration is completed, it is also necessary to stop pressing before the treated tailings can be taken out from the filter plate. This discontinuous operation mode of "feeding - stopping - pressing - stopping - taking out" severely restricts the processing efficiency and is difficult to meet the needs of large-scale tailings treatment.

[0008] Secondly, from the perspective of dehydration effect, simple physical pressing can discharge some free water, but it is difficult to completely remove the capillary water and bound water adsorbed in the gaps and inside of tailings particles. After pressing, the tailings are often compacted into hard lumps, and this physical structure instead hinders the further diffusion and evaporation of subsequent water, making it difficult for the dehydration process to proceed deeply, and ultimately resulting in a still relatively high moisture content of the overall tailings.

[0009] In summary, the existing filter plate pressing type tailings dehydration method is not only cumbersome to operate and unable to be continuous, resulting in low processing efficiency, but also has an unsatisfactory dehydration effect, and a large amount of water still remains inside the tailings.

[0010] Based on this, the present invention designs a gold mine tailings dehydration device to solve the above problems. Summary of the Invention

[0011] The purpose of the present invention is to provide a gold mine tailings dehydration device to solve the problems in the above-mentioned background technology.

[0016] As a further description of the above technical solution: The extrusion and dehydration mechanism includes a rotating cylinder rotatably connected inside the heating side frame.

[0017] As a further description of the above technical solution: The active pushing component includes a sliding push plate slidably connected in the sliding hole.

[0022] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In the present invention, a rotary drum, a sliding push plate, a magnetic plate, magnetic columns, a driving motor, a filter plate, and a vibrating motor are adopted. Under the action of the vibrating motor, the tailings form a continuously sliding flow state on the inclined filter plate. The driving motor drives the rotary drum and the sliding push plate to rotate synchronously, enabling the continuously sliding tailings on the upper side to automatically and continuously enter between two adjacent sliding push plates. This design completely gets rid of the operation limitations of traditional intermittent feeding, pressing, and taking out, realizes the whole process continuity of tailings from feeding to dehydration treatment, greatly improves the overall operation efficiency. During the continuous conveying process, when the sliding push plate moves to the contact position with the arc section of the filter plate, the structural design enables the filter plate to effectively squeeze the sliding push plate, forcing it to move towards the built-in magnetic columns. The space of the tailings filled between the two sliding push plates is forced to be compressed, and the water inside the tailings and in the particle gaps is efficiently squeezed out under this high pressure. These discharged waters can smoothly pass through the filter plate and flow along the inclined surface into the waste water collection frame below. Compared with traditional simple pressing, this device continuously squeezes and dehydrates the tailings during the movement process, not only discharging more free water, but also having a better removal effect on capillary water and part of the bound water, significantly reducing the final moisture content of the tailings. After being compressed and dehydrated, the tailings are continuously pushed by the sliding push plate, cross the push plate area, and smoothly transition to the inclined short straight section of the filter plate, and then are continuously output. The whole treatment process is smooth and compact, avoiding material accumulation and frequent start-stop operations.

[0023] 2. In the present invention, an extrusion wheel, an extrusion groove, a connecting column, a moving frame, a guiding hole, a dispersing tooth, and a heating side frame are adopted. By using the precise cooperation between the extrusion wheel and the extrusion groove, the connecting column is driven to perform a stable and controllable reciprocating movement in the horizontal direction. When the connecting column drives the moving frame to move leftward, through the precise limiting effect of the guiding hole, it is ensured that the cylinder, the moving strip, and the key component - the dispersing tooth can synchronously and orderly move forward to the left. These orderly arranged dispersing teeth can efficiently push and break the tailings that have been initially compressed into lumps, making them return to a loose state. This process significantly improves the uniformity of the tailings and lays a foundation for more thorough subsequent dehydration treatment. Although simple physical dispersion can improve the material state, the combined use of effective heat energy assistance can greatly improve the water removal efficiency. The present invention cleverly sets the heating side frame. After the dispersing teeth complete the operation of breaking and loosening the tailings, the loose tailings immediately enter or closely contact the heating side frame area. The heating side frame continuously provides heat energy, acting on the tailings particles that have been dispersed and have an increased surface area, accelerating the evaporation of the water inside and on the surface. This "dispersion + heating" composite treatment method, compared with simple physical pressing or natural drying, greatly enhances the water removal effect, can more effectively reduce the final moisture content of the tailings, and significantly shortens the overall drying cycle.

[0024] 3. In the present invention, an air frame, a contact plate, an extrusion plate, an air outlet valve, a connection plate, and a jet head are adopted. When the extrusion plate moves to the left, it will strongly squeeze the compressed gas in the air frame. These compressed gases are forced to pass through the air outlet valve, the air outlet pipe, and the connection plate, and finally are ejected at high speed through the uniformly distributed jet heads. The high-speed air flow precisely acts on the surface of the potentially agglomerated tailings that have been preliminarily compressed, generating a strong impact and dispersing effect. This pneumatic assistance does not act alone, but forms a synergistic effect with the function of the previously mentioned dispersing teeth. The air flow blown out by the jet heads can effectively loosen the external structure of the tailings agglomerates, and the subsequent dispersing teeth can more thoroughly break them internally. The cooperation of the two makes the loosening effect of the tailings far exceed that of single mechanical dispersion, achieving a more ideal and uniform loosening state. The present invention not only focuses on the physical form of the material, but also on the rapid removal of moisture. The high-speed flowing gas ejected by the jet heads, while completing the dispersion assistance function, the kinetic energy and possible temperature rise it carries can significantly accelerate the evaporation process of moisture on the surface and inside the capillary pores of the tailings particles. The rapidly flowing air flow can continuously replace the saturated wet air around the tailings, maintaining a relatively low local humidity environment, which greatly promotes the transfer of moisture to the gas phase and effectively shortens the time required for moisture evaporation. This air flow-assisted drying method, combined with the heat energy assistance of the heating side frame, forms a composite drying mechanism, enabling the internal moisture of the tailings to be removed more quickly and evenly, and significantly improving the overall drying efficiency.

[0029] By combining the dispersing tooth 19 and the air jet head 21, the agglomerated tailings after pressing dehydration can be dispersed and blown. The cooperation of the two makes the dispersion treatment effect of the tailings more ideal. The inclined filter plate 5 cooperates with the vibration motor 11, so that the tailings can smoothly slide down on the filter plate 5, and at the same time, it assists the subsequent tailings dispersion effect. The heating side frame 4 conducts a certain heating treatment on the tailings to make its dehydration effect better.

[0030] Specifically, as Figures 1-4 shown, a through moving hole 23 is opened outside the heating side frame 4, the moving bar 17 is horizontally slidably connected in the moving hole 23, the dispersing tooth 19 is arranged on the filter plate 5, and the filter plate 5 is composed of an inclined long straight section, an arc section and an inclined short straight section from left to right. A bearing 14 is sleeved outside the rotating shaft 13, and the bearing 14 is arranged on the inner wall of the dehydration treatment tank 1.

[0031] Specifically, as Figures 1-3 shown, a collection box 6 is installed in the dehydration treatment tank 1, the position of the collection box 6 corresponds to the bottom end of the filter plate 5, a second access door 9 is hinged at the position corresponding to the collection box 6 on the right side of the dehydration treatment tank 1, and a first access door 2 is hinged on the front of the dehydration treatment tank 1.

[0032] Specifically, as Figures 2-3 shown, a waste water frame 7 is installed on the inner bottom wall of the dehydration treatment tank 1, a drain valve 8 is communicated with the left side of the waste water frame 7 and is installed through the side of the dehydration treatment tank 1, the feeding hopper 3 is located above the left end of the filter plate 5, and the moving bar 17 is located above the inclined short straight section.

[0033] Specifically, as Figures 4-6As shown, the extrusion and dewatering mechanism 12 includes a rotating drum 121 rotatably connected inside the heating side frame 4. The rotating drum 121 is fixedly connected to the end of a rotating shaft 13. A sliding hole 124 is formed on the outer side of the rotating drum 121, and sliding grooves 125 are formed on both the front and rear sides of the inner wall of the rotating drum 121. An active pushing component 122 is slidably connected in the sliding hole 124 and the sliding grooves 125, and a magnetic column 123 is fixedly connected inside the rotating drum 121.

[0034] The active pushing component 122 includes a sliding push plate 1221 slidably connected in the sliding hole 124. One end of the sliding push plate 1221 located inside the rotating drum 121 is fixedly connected with a magnetic plate 1223. Extension sliders 1222 are installed on both the front and rear sides of the sliding push plate 1221, and the extension sliders 1222 are slidably connected in the sliding grooves 125. The sides of the magnetic plate 1223 close to the magnetic column 123 have the same magnetism. The rotation trajectory of the sliding push plate 1221 coincides with the arc segment of the filter plate 5.

[0035] The extension slide plate and the sliding grooves 125 limit and guide the movement of the sliding push plate 1221 to prevent the sliding push plate 1221 from falling off or wobbling randomly. During the rotation of the rotating drum 121, the sliding push plate 1221 is driven to rotate. The tailings falling from the upper side will enter between the two sliding push plates 1221. When the sliding push plate 1221 contacts the arc segment of the filter plate 5, the filter plate 5 will squeeze the sliding push plate 1221 to move closer to the magnetic column 123. At this time, the space between the two sliding push plates 1221 is filled with tailings and the space is compressed, and the tailings will be squeezed to discharge water during this process.

[0036] Specifically, as Figures 7-8 shown, the movement control mechanism 16 includes an extrusion wheel 161 installed outside the rotating shaft 13. An extrusion groove 162 is formed on the side of the extrusion wheel 161 close to the heating side frame 4. A connecting column 163 is slidably connected in the extrusion groove 162, and a sliding sleeve 166 is slidably connected outside the connecting column 163. The sliding sleeve 166 is installed outside the heating side frame 4.

[0037] One end of the connecting column 163 is fixedly connected with a moving frame 164. A guiding hole 165 is formed on the front surface of the moving frame 164. The cylinder 18 is slidably connected in the guiding hole 165, and the extrusion and jetting mechanism 22 is arranged on the side of the extrusion wheel 161.

[0038] The extrusion wheel 161 controls the connecting column 163 to perform reciprocating movement in the horizontal direction through the extrusion groove 162. When the connecting column 163 and the moving frame 164 move to the left, the cylinder 18, the moving bar 17, and the dispersing teeth 19 are controlled to move to the left through the guiding hole 165; Specifically, as Figure 7 and Figure 9As shown in the figure, the extrusion jet mechanism 22 includes an air frame 221 fixedly installed outside the heating side frame 4. A pressing plate 222 is slidably connected inside the air frame 221. A cross bar 223 is fixedly connected to the side of the pressing plate 222. The cross bar 223 penetrates and is slidably connected outside the air frame 221. A contact plate 224 is fixedly connected to the end of the cross bar 223 outside the air frame 221. The contact plate 224 is arranged on the side of the extrusion wheel 161.

[0039] A spring 225 is fixedly connected to the side of the pressing plate 222. The spring 225 is installed inside the air frame 221. An intake valve 226 is communicated with the left side surface of the air frame 221. An exhaust valve 227 is communicated with the air frame 221. An exhaust pipe 228 is communicated with the exhaust valve 227. The end of the exhaust pipe 228 is communicated with the connecting plate 20. A support sleeve 229 is sleeved outside the exhaust pipe 228. The support sleeve 229 is fixedly connected to the heating side frame 4.

[0040] During the rotation of the extrusion wheel 161, it will intermittently squeeze the contact plate 224 to move left and right. When the pressing plate 222 moves leftward, it will squeeze the gas inside the air frame 221 to be ejected through the exhaust valve 227, the exhaust pipe 228, the connecting plate 20 and the jet head 21; the intake valve 226 and the exhaust valve 227 cooperate to enable the pressing plate 222 to unidirectionally squeeze and discharge the gas during the left and right reciprocating movement.

[0041] Working principle: When in use, the tailings to be dewatered are poured onto the filter plate 5 through the feeding hopper 3. At the same time, the driving motor 15 and the vibration motor are controlled to work. While the vibration motor is working, the filter plate 5 is controlled to vibrate, so that the tailings raw materials on the filter plate 5 slide downward. The driving motor 15 controls the rotation of the rotating shaft 13 and the rotating cylinder 121. During the rotation of the rotating cylinder 121, the sliding push plate 1221 is driven to rotate. The tailings sliding from the upper side will enter between the two sliding push plates 1221. When the sliding push plate 1221 contacts the arc section of the filter plate 5, the filter plate 5 will squeeze the sliding push plate 1221 to move close to the magnetic column 123. At this time, the space between the two sliding push plates 1221 is filled with tailings and the space is compressed. The tailings will be squeezed out of water during this process. The water flows downward through the filter plate 5 into the waste water frame 7 until the compressed tailings cross the sliding push plate 1221 and enter the inclined short straight section; During the rotation of the rotating shaft 13, the extrusion wheel 161 is controlled to rotate. The extrusion wheel 161 controls the connecting column 163 to perform reciprocating movement in the horizontal direction through the extrusion groove 162. When the connecting column 163 and the moving frame 164 move to the left, the cylinder 18, the moving strip 17 and the dispersing teeth 19 are controlled to move to the left through the guiding hole 165. The dispersing teeth 19 push the tailings after being compressed and agglomerated to the left to be dispersed. At the same time, the tailings slide to the right due to the vibration of the inclined filter plate 5 and the vibration motor 11. The tailings passing through the dispersing teeth 19 are dispersed again. During the rotation of the extrusion wheel 161, the contact plate 224 is intermittently squeezed to move left and right. When the extrusion plate 222 moves to the left, it squeezes the gas in the air box 221 to be sprayed out through the air outlet valve 227, the air outlet pipe 228, the connecting plate 20 and the jet head 21. The rapidly sprayed gas blows on the agglomerated tailings and cooperates with the dispersing teeth 19 to disperse the tailings. The heating side frame 4 works to dissipate heat to heat the tailings after pressing drainage and dispersion to remove moisture. Finally, the dehydrated tailings fall into the collection box 6.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, shall be covered by the protection scope of the present invention.
