Description

Technical Field

[0001] This invention belongs to the field of tailings recycling technology, and specifically relates to a tailings fine sand recycling device. Background Technology

[0002] In the process of recovering fine sand from tailings, screening devices are required to process the tailings. Existing tailings fine sand recovery equipment, while meeting the basic requirement of screening and processing tailings for fine sand recovery, and using buffer structures to cushion the tailings falling onto the screening structure and prevent wear, only provides this basic function. It lacks the flexibility to adjust the tailings' position on the screening structure, resulting in the tailings falling to a fixed location after buffering. Consequently, the continuously falling sections of the screening structure are easily damaged over time, affecting its lifespan. Therefore, it does not fully meet the needs of users.

[0003] For example, utility model patent document CN217988587U discloses a tailings dewatering screen for mining. In this patent document, a slow-fall mechanism is provided inside the screening box. The slow-fall mechanism includes a dustproof rubber ring, a movable roller, a partition baffle, a movable shaft, and a movable bearing. The movable shaft is movably installed inside the screening box, and the movable roller is fixedly installed on the movable shaft. A partition baffle is fixedly installed inside the movable roller. During the conveying process, the tailings first fall into the compartment inside the movable roller, thus preventing large pieces of tailings from directly impacting the screen plate. The tailings fall into the movable roller. Once inside the compartment, the drive motor can be started. After starting the drive motor, the movable drum will rotate. During the rotation of the movable drum, the tailings in the compartment will rotate along with the dividing baffle. As it approaches the screen plate, the tailings will slowly roll down, thereby reducing the speed at which the tailings fall and reducing the impact on the screen plate. However, since the screening structure cannot flexibly adjust the position of the tailings on the screening structure, the tailings will always impact the same position of the screening structure. After long-term use, the screening structure is still easily damaged, which will cause great inconvenience to users. Summary of the Invention

[0004] In view of this, the present invention addresses the shortcomings of the prior art by providing a tailings fine sand recovery device. This device not only meets the basic requirement of screening tailings and recovering the fine sand from them, but also buffers the process of tailings falling onto the screening structure and flexibly adjusts the position of the tailings on the screening structure, thereby effectively avoiding damage to the screening structure and significantly extending its service life.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: a tailings fine sand recovery device, including a base frame, a plurality of vibration springs are provided on the top of the base frame, a mounting frame is provided on the top of the plurality of vibration springs, a plurality of vibration motors are provided on the mounting frame, a screening trough is provided on the mounting frame at an angle to the right via a first bracket, a receiving trough is provided on the mounting frame at an angle to the right via a second bracket, located below the screening trough, an extension trough extending to the right side of the receiving trough is provided on the right end of the screening trough, a U-shaped mounting frame is provided on the left end of the top of the base frame, a feed hopper is provided through the mounting frame, two vertical plates are slidably provided on the front and rear sides of the top left end of the mounting frame, a linear slide is provided on the front side of the top left end of the mounting frame along the left and right direction, a connecting plate is provided between the slide seat of the linear slide and the corresponding vertical plate, a receiving groove adapted to the feed hopper is rotatably provided on the upper end of the two vertical plates, and a telescopic push rod is hinged between the inner end of the two vertical plates and the outer end of the receiving groove.

[0006] As a further improvement of the present invention, the top of the base frame is provided with a plurality of guide tubes, and the bottom of the mounting frame is provided with a plurality of guide rods that are respectively connected to the corresponding guide tubes.

[0007] As a further improvement of the present invention, connecting grooves are respectively provided on the front and rear sides of the top left end of the mounting frame, and connecting sliders are provided on the bottom of the vertical plate, which are slidably connected to the connecting grooves. The vertical cross-sections of both the connecting grooves and the connecting sliders are T-shaped. Through the cooperation of the connecting grooves and the connecting sliders, the mounting frame and the vertical plate can slide left and right. Because the vertical cross-sections of both the connecting grooves and the connecting sliders are T-shaped, it is possible to avoid the connecting sliders from shifting in a direction other than left and right relative to the connecting grooves, so that the vertical plate slides more smoothly relative to the mounting frame.

[0008] As a further improvement of the present invention, the top front side of the mounting frame is also vertically provided with multiple L-shaped fixing frames located outside the screening tank and the receiving tank. The inner sidewalls of the upper ends of the multiple fixing frames are respectively provided with fixing grooves. Fixed sliders are slidably arranged in the multiple fixing grooves. The outer ends of the multiple fixed sliders are also provided with crossbars that are transversely connected to and slidably connected to the front and rear sidewalls of the screening tank. The front and rear sidewalls of the screening tank are provided with through holes that are adapted to the multiple crossbars. The multiple crossbars are provided with multiple material-pulling claws located inside the screening tank. The outer ends of the multiple fixed sliders and the front outer wall of the screening tank are also provided with connecting springs sleeved on the outside of the crossbars. The front sidewalls of the multiple fixing grooves are provided with a first inclined surface. The front ends of the multiple fixed sliders are provided with a second inclined surface that is adapted to the first inclined surface.

[0009] As a further improvement of the present invention, a first reinforcing rod is further provided between the first bracket and the mounting frame, and a second reinforcing rod is further provided between the second bracket and the mounting frame. The first reinforcing rod can enhance the firmness of the connection between the first bracket and the mounting frame; the second reinforcing rod can enhance the firmness of the connection between the second bracket and the mounting frame.

[0010] As a further improvement of the present invention, a third reinforcing rod is provided between the first support and the screening tank, and a fourth reinforcing rod is provided between the second support and the collecting tank. The third reinforcing rod can enhance the firmness of the connection between the first support and the screening tank; the fourth reinforcing rod can enhance the firmness of the connection between the second support and the collecting tank.

[0011] As a further improvement of the present invention, the right end of the base frame is provided with a first inlet and outlet, and the right end of the mounting frame is provided with a second inlet and outlet.

[0012] As a further improvement of the present invention, an extension plate is provided at the bottom side of the base frame, and an anchor bolt for connecting to the ground is provided on the extension plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: Firstly, after the tailings to be screened are added to the feed hopper, they first fall into the receiving trough for buffering before falling into the screening trough for screening. This avoids damage to the screening trough by preventing the tailings from falling directly onto it. Furthermore, the tilt angle of the receiving trough can be adjusted using two telescopic push rods, thereby regulating the position of the tailings falling from the receiving trough onto the screening trough and preventing them from falling directly into a fixed position for an extended period, further minimizing damage. Additionally, the position of the two vertical plates and the receiving trough in the left-right direction can be adjusted using a linear slide table, preventing the tailings falling from the feed hopper from falling into a fixed position on the receiving trough for an extended period, thus avoiding damage. Simultaneously, the position of the tailings falling from the receiving trough onto the screening trough can also be changed, thus preventing damage to the screening trough.

[0014] Secondly, the cooperation of the guide tube and the guide rod enables the mounting frame to vibrate vertically relative to the base frame smoothly, preventing non-vertical displacement and avoiding damage to multiple vibration springs.

[0015] Thirdly, when the screen tank vibrates, the cooperation of the fixed frame, fixed chute, fixed slider, through hole, connecting spring, first inclined surface and second inclined surface enables the crossbar and the material-pulling claw to slide back and forth relative to the screen tank, thereby automatically moving the tailings in the screen tank, so that the fine sand can be separated from the screen tank more thoroughly, and thus more fully screened out of the screen tank and fall into the receiving trough.

[0016] Fourth, the extension trough allows for the placement of materials in the screening tank and the receiving tank, enabling users to collect materials from both troughs separately. The coordination of the first and second inlets and outlets facilitates the collection of fine sand from the receiving tank.

[0017] Fifth, the combination of the extension plate and anchor bolts can prevent the device from easily shifting during operation. Attached Figure Description

[0021] To better understand the present invention, the following embodiments further illustrate the content of the invention, but the scope of protection of the present invention is not limited to the following embodiments. Numerous specific details are set forth in the following description to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details.

[0022] like Figure 1 , 2 As shown in Figure 3, a tailings fine sand recovery device includes a base frame 101. Multiple vibration springs 102 are mounted on the top of the base frame 101. A mounting frame 103 is mounted on the top of the multiple vibration springs 102. Multiple vibration motors 104 are mounted on the mounting frame 103. A screening tank 105 is inclined to the right on the mounting frame 103 via a first bracket 119. A receiving trough 106 located below the screening tank 105 is also inclined to the right on the mounting frame 103 via a second bracket 120. An extension trough 107 extending to the right side of the receiving trough 106 is also provided at the right end of the screening tank 105. The base... A U-shaped mounting bracket 108 is provided at the top left end of the frame 101. A feed hopper 109 is provided through the mounting bracket 108. Two vertical plates 110 are slidably provided on the front and rear sides of the top left end of the mounting frame 103. A linear slide 111 is also provided on the front side of the top left end of the mounting frame 103 along the left and right directions. A connecting plate 112 is provided between the slide of the linear slide 111 and the corresponding vertical plate 110. The upper ends of the two vertical plates 110 are rotatably provided with receiving grooves 113 that are adapted to the feed hopper 109. A telescopic push rod 114 is also hinged between the inner end of the two vertical plates 110 and the outer end of the receiving groove 113.

[0023] like Figure 1As shown, the top of the base frame 101 is provided with multiple guide cylinders 115, and the bottom of the mounting frame 103 is provided with multiple guide rods 116 that are respectively connected to the corresponding guide cylinders 115. Through the guiding cooperation of the vertical sliding movement of the guide cylinders 115 and the guide rods 116, the mounting frame 103 can be made to vibrate vertically smoothly relative to the base frame 101, avoiding non-vertical displacement and preventing damage to the multiple vibration springs 102.

[0024] like Figure 2 As shown, the mounting frame 103 has connecting grooves 117 on both the front and rear sides of its top left end, and a connecting slider 118 that slides slidably with the connecting grooves 117 is provided at the bottom of the vertical plate 110. Both the connecting grooves 117 and the connecting slider 118 have T-shaped vertical sections. Through the cooperation of the connecting grooves 117 and the connecting slider 118, the mounting frame 103 and the vertical plate 110 can slide left and right. Because both the connecting grooves 117 and the connecting slider 118 have T-shaped vertical sections, the connecting slider 118 can avoid offset from the connecting grooves 117 in a direction other than left and right, allowing the vertical plate 110 to slide more smoothly relative to the mounting frame. The right end of the base frame 101 also has a first inlet / outlet, and the right end of the mounting frame 103 also has a second inlet / outlet.

[0025] The user can place one receiving device in a position compatible with the discharge port of the extension trough 107 to prepare for collecting the tailings falling from the screening trough 105. Through the first and second inlets / outlets, another receiving device can be placed in a position compatible with the receiving trough 106 to prepare for collecting the material falling from the receiving trough 106. Subsequently, multiple vibrations can be activated, and through the cooperation of multiple vibration springs 102, the mounting frame 103, the first support 119, the screening trough 105, the second support 120, and the receiving trough 106 will vibrate, preparing for the screening of the tailings.

[0026] The tailings to be screened can then be added to the feed hopper 109. The tailings will first fall into the receiving trough 113 for buffering before falling into the screening tank 105 for screening. This prevents damage to the screening tank 105 by avoiding direct fall of the tailings onto it. Furthermore, the inclination angle of the receiving trough 113 can be adjusted using two telescopic push rods 114, thereby regulating the position of the tailings falling from the receiving trough 113 onto the screening tank 105 and preventing the tailings from falling directly onto the screen for an extended period. The fixed position on the screen 105 further avoids damage to the screen 105; in addition, the position of the two vertical plates 110 and the receiving trough 113 in the left and right directions can be adjusted by the linear slide table 111, thereby preventing the tailings falling from the feed hopper 109 from falling on the fixed position on the receiving trough 113 for a long time, thus avoiding damage to the receiving trough 113, and at the same time changing the position of the tailings falling from the receiving trough 113 onto the screen 105, thereby simultaneously avoiding damage to the screen 105.

[0027] After the tailings fall onto the screen trough 105, small particles of fine sand pass through the screen holes of the screen trough 105 and fall into the receiving trough 106. Larger particles of ore, unable to pass through the screen holes, remain in the screen trough 105 and slide down the inclined direction of the vibrating screen trough 105 into the receiving trough 106, then into a receiving device. Small particles of fine sand slide down the inclined direction of the vibrating receiving trough 106 and fall into another receiving device. Then, the feeding of tailings to be screened into the feed hopper 109 is paused, and both receiving devices are cleaned and reset. Afterward, the tailings screening process can continue.

[0028] According to another embodiment of the invention, such as Figure 4 , 5As shown in Figures 6 and 7, the top front side of the mounting frame 103 is also vertically provided with multiple L-shaped fixing brackets 201 located outside the screening tank 105 and the receiving tank 106. The inner sidewalls of the upper ends of the multiple fixing brackets 201 are respectively provided with vertical fixing grooves 202. Fixing sliders 203 are slidably disposed in the multiple fixing grooves 202. The outer ends of the multiple fixing sliders 203 are also provided with crossbars 204 that are transversely penetrating and slidably connected to the front and rear sidewalls of the screening tank 105. The front of the screening tank 105... The rear side wall is provided with through holes 205 that are adapted to multiple crossbars 204. Multiple material-pulling claws 206 located inside the screening tank 105 are provided on the multiple crossbars 204. The outer ends of multiple fixed sliders 203 and the front outer wall of the screening tank 105 are also provided with connecting springs 207 sleeved on the outside of the crossbars 204. The front side wall of multiple fixed slide grooves 202 is provided with a first inclined surface 208. The front end of multiple fixed sliders 203 is provided with a second inclined surface 209 adapted to the first inclined surface 208.

[0029] During the process of vibrating the screen trough 105 and the receiving trough 106 to screen the tailings, the screen trough 105, during its vertical vibration, drives the crossbar 204 and the fixed slider 203 to slide vertically relative to the fixed chute 202. With the cooperation of the first inclined surface 208 and the second inclined surface 209, and the rebound and reset action of the connecting spring 207, the crossbar 204 and the material-pulling claws 206 slide back and forth relative to the screen trough 105. This causes the multiple material-pulling claws 206 to automatically move and agitate the tailings in the screen trough 105, allowing the fine sand to separate more thoroughly from the screen trough 105 and fall more fully into the receiving trough 106, thereby further improving the effect and efficiency of screening the fine sand in the tailings.

[0030] According to another embodiment of the invention, such as Figure 8 As shown, a first reinforcing rod 301 is provided between the first bracket 119 and the mounting frame 103, and a second reinforcing rod 302 is provided between the second bracket 120 and the mounting frame 103. The first reinforcing rod 301 can enhance the firmness of the connection between the first bracket 119 and the mounting frame 103; the second reinforcing rod 302 can enhance the firmness of the connection between the second bracket 120 and the mounting frame 103.

[0031] According to another embodiment of the invention, such as Figure 8As shown, a third reinforcing rod 303 is provided between the first support 119 and the screening tank 105, and a fourth reinforcing rod 304 is provided between the second support 120 and the collection tank. The third reinforcing rod 303 can enhance the firmness of the connection between the first support 119 and the screening tank 105; the fourth reinforcing rod 304 can enhance the firmness of the connection between the second support 120 and the collection tank.

[0032] According to another embodiment of the invention, such as Figure 3 As shown, the bottom side of the base frame 101 is also provided with an extension plate 305, and the extension plate 305 is also provided with anchor bolts 306 for connecting to the ground. The user can make the anchor bolts 306 pass through the extension plate 305 and connect to the ground, thereby preventing the device from easily shifting during operation.

[0033] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
