Description

Technical Field

[0001] This invention relates to the field of ore processing equipment, specifically an ore conveying, screening, and desliming equipment. Background Technology

[0002] In ore mining operations, ore is usually collected mixed with soil. To maximize the amount of ore transported, it is necessary to pre-separate the ore and soil at the mining site. Current technology typically uses a mud-stone separator to separate the ore and soil. In practice, the mud-stone separator drives the mud-stone mixture forward through multiple roller screens, causing the mixture to tumble and bounce on the screens. This allows the soil to leak out through the gaps in the roller screens, thus separating the ore from the soil.

[0003] However, when separating mud and rock mixtures using the above method, smaller pieces of ore are not easily driven by the roller screen, causing them to get stuck in the gaps of the roller screen and block the gaps. This prevents the mud from passing through smoothly, resulting in a higher mud content in the ore and reducing the desliming effect. In addition, the method of turning and shaking the mud and rock mixture by using the roller screen can easily cause a large impact on the brittle ore, causing the ore to break into small pieces and leak out with the mud, thus reducing the output. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an ore conveying, screening and desliming treatment device, including a conveyor belt, the conveyor belt having an inwardly concave arc structure, a U-shaped frame provided in the middle of the upper side of the conveyor belt, a separation component rotatably provided on the right side inside the U-shaped frame to extract the ore mixed in the mud to the upper side of the mud, a cleaning component for diverting and brushing the ore provided on the left side inside the U-shaped frame, and a feeding component for classifying the ore provided on the left side of the upper side of the conveyor belt.

[0005] The separating component includes a rotating frame rotatably disposed in the middle and right side between two vertical sections of the U-shaped frame. The outer side of the rotating frame is an arc-shaped surface that fits the conveyor belt, and the inner side of the rotating frame is a plane. Inside the rotating frame, two rotating plates are rotatably disposed along one of its diagonals. The rotating plates are provided with comb grooves at equal intervals along their length. Inside the rotating frame, two comb plates are rotatably disposed along the other diagonal. The distance between the axis of the comb plates and the rotating plates and the inner wall of the rotating frame is equal. Inside the rotating frame, two vibrating plates are slidably disposed back and forth. The two vibrating plates are located between the corresponding comb plates and rotating plates. The vibrating plates are provided with slots at equal intervals along their length.

[0006] The cleaning component includes a converging plate fixedly installed on the lower left side of the U-shaped frame. The converging plates are combined to form an opening shape that is evenly spaced along the width of the conveyor belt. A diverter plate is hinged to the left side of each converging plate. Cleaning bristles are provided on the side of the two diverter plates that are close to each other and corresponding to the opening of the converging plate. A spring is provided between two adjacent diverter plates.

[0007] The rotating frame, in conjunction with the rotating plate, shovels the mud-ore mixture into the interior of the rotating frame. The shaking plate shakes the mud-ore mixture, causing the mud to leak out from the gaps in the comb plate. Then, the comb plate is opened to let the ore fall onto the mud. The diversion plate further brushes the mud on the surface of the ore. Finally, the ore is collected by the feeding component.

[0008] As a preferred embodiment of the present invention, the unloading component includes an L-shaped frame installed at the rear of the conveyor belt. The horizontal section of the L-shaped frame is located on the upper side of the conveyor belt. Several sets of unloading rollers are rotatably arranged on the lower part of the horizontal section of the L-shaped frame along the transmission direction of the conveyor belt. The spacing between each set of unloading rollers gradually decreases from right to left. The unloading rollers in the same set are gradually inclined to the left front. The number of unloading rollers in the same set gradually increases and the spacing gradually decreases from right to left. A spiral lever is provided on the outer side of the unloading roller. The lower end of the unloading roller is arc-shaped and fits against the upper side of the conveyor belt.

[0009] As a preferred embodiment of the present invention, the upper sides of each set of feeding rollers are interconnected by belts, and an actuator motor is installed on the upper front side of the L-shaped frame. The output shaft of the actuator motor is connected to each set of feeding rollers by belts.

[0010] As a preferred embodiment of the present invention, a pawl is provided on the rear side of the rotating frame corresponding to the position of the rotating plate, and a ratchet is provided on the outer side of the rotating shaft of the rotating plate corresponding to the position of the pawl, and the rotating plate and the rotating frame rotate in opposite directions.

[0011] As a preferred embodiment of the present invention, an inclined block is elastically slidably arranged on the rear side of the rotating frame corresponding to the position of the comb plate. A pushing circular plate is arranged at the rear of the inclined block. A pushing member is arranged on the rear side wall inside the U-shaped frame corresponding to the lower right position of the rotating frame to push the pushing circular plate backward. A gear is installed at the front end of the rotating shaft of the comb plate. An incomplete gear is installed on the front wall inside the U-shaped frame corresponding to the outer side of the rotating shaft of the rotating frame. The teeth of the incomplete gear face upward and the number of teeth is equal to one-quarter of the number of teeth of the gear.

[0012] As a preferred embodiment of the present invention, a return spring is provided between the front end of the shaking plate and the rotating frame, the two shaking plates are connected by a support rod, and a push plate is installed on the inner rear wall of the U-shaped frame at the position corresponding to the outer side of the rotating frame's pivot. The front side of the push plate is provided with protrusions that push the support rod forward at equal intervals along its circumference.

[0013] As a preferred embodiment of the present invention, a rotating motor is installed on the upper right side of the U-shaped frame, and the output shaft of the rotating motor is connected to the rotating shaft of the rotating frame via a belt.

[0014] As a preferred embodiment of the present invention, a pushing cylinder is installed on the upper left side of the U-shaped frame, and an inclined panel is slidably arranged on the upper left side of the U-shaped frame. The telescopic end of the pushing cylinder is connected to the inclined panel. An auxiliary rod is provided on the upper left side of the diverter plate, and an inclined surface is provided on the left side of the inclined panel to push the two diverter plates corresponding to the opening of the converging plate in a direction away from each other.

[0015] The beneficial effects of this invention are as follows:

[0016] I. This invention employs a rotating frame to shovel a mixture of mud and stone into its interior. A vibrating plate shakes the mixture, separating the mud from the ore. A comb plate first exposes the separated mud onto a conveyor belt, then opens to allow the ore to fall onto the mud, thus achieving separate placement of mud and ore. A cleaning component further brushes away the mud adhering to the outside of the ore. Finally, a feeding component feeds the ore from the top, resulting in a lower mud content in the ore. Furthermore, it prevents the ore from breaking and allows for the feeding of smaller pieces, increasing ore yield.

[0017] Second, the present invention uses a rotating frame with its bottom attached to the conveyor belt to scoop up the mud-stone mixture. The mud-stone mixture is confined inside the rotating frame by a rotating plate that rotates in one direction. The shaking plate can then fully separate the ore from the mud, thereby improving the separation effect.

[0018] Third, the present invention uses a push cylinder to drive the inclined plate to push the two diversion plates corresponding to the opening of the converging plate in a direction away from each other, so that the ore will not be blocked between the diversion plates, thereby ensuring that the ore can move and be fed smoothly.

[0019] Fourth, the present invention uses a spiral-shaped lever set on the outer side of the feeding roller to push the ore forward and upward at the same time when rotating, so as to facilitate the forward movement of the ore stuck in the mud, so that the irregularly shaped ore can be fed smoothly. Moreover, the different gaps between each set of feeding rollers can classify the ore for feeding, thereby ensuring the efficiency of feeding. Attached Figure Description

[0032] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0033] See Figure 1A ore conveying, screening, and desliming treatment device includes a conveyor belt 1, which has an inwardly concave arc-shaped structure. A U-shaped frame 11 is provided in the middle of the upper side of the conveyor belt 1. A separation component 2 is rotatably arranged on the right side of the U-shaped frame 11 to extract ore mixed in the mud to the upper side of the mud. A cleaning component 3 is provided on the left side of the U-shaped frame 11 to divert and brush the ore. A feeding component 4 is provided on the left side of the upper side of the conveyor belt 1 to classify the ore. When it is necessary to screen and deslim the mud-stone mixture, the mud-stone mixture is first placed on the conveyor belt 1. Then, the conveyor belt 1 is started to convey the mud-stone mixture to the left. Subsequently, the mud and ore are separated by the separation component 2, so that the ore is placed on the upper side of the mud. Then, the mud adhering to the outside of the ore is swept off by the cleaning component 3 and the ore is diverted. Finally, the ore is classified and fed by the feeding component 4.

[0034] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The separating component 2 includes a rotating frame 21 rotatably disposed in the middle and right part between two vertical sections of the U-shaped frame 11. The outer surface of the rotating frame 21 is an arc-shaped surface that fits the conveyor belt 1, and the inner surface of the rotating frame 21 is a plane. Two rotating plates 22 are rotatably disposed inside the rotating frame 21 along one of its diagonals. The rotating plates 22 are provided with comb grooves at equal intervals along their length. Pawls 221 are provided on the rear side of the rotating frame 21 corresponding to the positions of the rotating plates 22. Ratchets 222 are provided on the outer side of the rotating shaft of the rotating plates 22 and corresponding to the positions of the pawls 221. The rotating plates 22 rotate in the opposite direction to the rotating frame 21. A rotating motor 25 is installed on the upper right side of the U-shaped frame 11. The output shaft of the rotating motor 25 is connected to the rotating shaft of the rotating frame 21 via a belt. When the mud-stone mixture is placed... When the material is placed on conveyor belt 1 and conveyed to the left, the rotating motor 25 is started to drive the two rotating frames 21 to rotate in the opposite direction of the movement of conveyor belt 1. This causes the rotating frames 21 to rotate and scoop the mud and stone mixture into their interior. When the rotating frames 21 scoop, they drive the rotating plate 22 to move synchronously. This causes the rotating plate 22 to contact the mud and stone mixture first. The reaction force of the mud and stone mixture on the rotating plate 22 causes it to rotate in the opposite direction of the rotation of the rotating frames 21. This allows the mud and stone mixture to enter the interior of the rotating frames 21 from between the rotating plate 22 and the inner wall of the rotating frames 21. Furthermore, through the cooperation of the ratchet 222 and the pawl 221, the rotating plate 22 can only rotate in one direction. This ensures that the mud and stone mixture can only enter the interior of the rotating frames 21 from the rotating plate 22, which facilitates the separation of mud and stone.

[0035] In this embodiment, the two rotating frames 21 rotate at 90° angles to each other, so that when one rotating frame 21 shakes and separates the mud and stone mixture, the other rotating frame 21 can shovel the mud and stone mixture, thereby ensuring the mud removal effect of the ore.

[0036] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 Inside the rotating frame 21, two comb plates 23 are rotatably arranged along its other diagonal position. The distance between the axis of each comb plate 23 and the axis of the rotating plate 22 and the inner wall of the rotating frame 21 is equal. On the rear side of the rotating frame 21, a ramp block 231 is elastically slidably arranged corresponding to the position of the comb plate 23. A pushing circular plate 232 is arranged at the rear of the ramp block 231. On the rear side wall inside the U-shaped frame 11, corresponding to the lower right position of the rotating frame 21, a pushing member 233 is arranged to push the pushing circular plate 232 backward. A gear 234 is installed at the front end of the rotating shaft of the comb plate 23. Inside the U-shaped frame 11... An incomplete gear 235 is installed on the front wall at the outer position of the rotating frame 21. The teeth of the incomplete gear 235 face upward and the number of teeth is equal to one-quarter of the number of teeth of the gear 234. In the initial state, the inclined block 231 extends out under its own elastic force to block the side of the comb plate 23, so that the comb plate 23 is in the position of closing the side of the rotating frame 21 in the initial state. Thus, after the mud and stone mixture enters the rotating frame 21, the comb plate 23 can cooperate with the rotating plate 22 to restrict the mud and stone mixture inside the rotating frame 21, so as to facilitate the shaking and separation of the mud and stone mixture.

[0037] See Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6Two vibrating plates 24 are slidably arranged inside the rotating frame 21. The two vibrating plates 24 are respectively located between the comb plate 23 and the rotating plate 22 at corresponding positions. The vibrating plates 24 have slots evenly spaced along their length. A return spring 241 is provided between the front end of the vibrating plate 24 and the rotating frame 21. The two vibrating plates 24 are connected by a support rod. A push plate 242 is installed on the inner rear wall of the U-shaped frame 11 at the position corresponding to the outer side of the rotating shaft of the rotating frame 21. The front side of the push plate 242 has forward pushing supports evenly spaced along its circumference. The protruding strip 243 of the rod; when the mud and stone mixture is confined inside the rotating frame 21, the rotating frame 21 continues to rotate, driving the two shaking plates 24 to rotate synchronously. The two shaking plates 24 drive the support rod to rotate. When the support rod rotates, the elastic force of the return spring 241 causes it to rotate along the side of the push plate 242, thereby causing the push plate 242 to push the rotating shaking plate 24 to shake back and forth through the protruding strip 243. This causes the shaking plate 24 to drive the mud and stone mixture to shake back and forth through the slots opened on it, and can break up the clumps of mud.

[0038] In actual operation, after the soil is broken up by the shaking plate 24, it leaks out from the gap between the rotating plate 22 and the comb plate 23 onto the conveyor belt 1. Then, the rotating frame 21 drives the pushing plate 232 to rotate to the pushing member 233 via the inclined block 231. This causes the pushing member 233 to push the pushing plate 232 backward via the inclined surface. The pushing plate 232 drives the inclined block 231 to move backward until it no longer obstructs the comb plate 23. At this time, the corresponding comb plate 23 rotates to a horizontal position, so that the comb plate 23... Under the influence of gravity, the frame rotates to a vertical position, thereby opening the side of the rotating frame 21 and allowing the ore to fall onto the top of the soil. Then, the rotating frame 21 drives the comb plate 23 to continue rotating. The comb plate 23 drives the gear 234 to mesh with the incomplete gear 235, so that the incomplete gear 235 drives the comb plate 23 to rotate 90° through the gear 234, thereby rotating the comb plate 23 to the initial position and engaging with the inclined surface block 231, so that the inclined surface block 231 blocks the side of the comb plate 23 again.

[0039] It should be noted that the rotating frame 21 is equipped with baffles and baffles, which allow the comb plate 23 to rotate only 90°, thus facilitating the limiting and closing of the comb plate 23.

[0040] See Figure 1 and Figure 8The cleaning component 3 includes a converging plate 31 fixedly installed on the lower left side of the U-shaped frame 11. The converging plates 31 are combined to form an opening shape that is evenly spaced along the width direction of the conveyor belt 1. A diverting plate 32 is hinged to the left side of each converging plate 31. Cleaning bristles 33 are provided on the side of the two diverting plates 32 that are close to each other, corresponding to the opening of the converging plate 31. A spring is provided between two adjacent diverting plates 32. When the ore falls onto the upper side of the soil, the conveyor belt 1 moves the ore to the converging plate 31. The converging plate 31 diverts the ore between the two plates through the opening structure. Then, the conveyor belt 1 moves the ore along the converging plate 31 to the diverting plate 32. The diverting plate 32 brushes the surface of the moving ore with the cleaning bristles 33. When the volume of the ore between the diverting plates 32 is inconsistent, the gap between the diverting plates 32 can be adaptively adjusted by the oscillation of the diverting plate 32 pushed by the ore and the compression of the spring force, so as to cope with various situations.

[0041] See Figure 8 To address the problem of blockage and accumulation of large and abundant ore at the diversion plate 32, the following design is implemented: a pushing cylinder 34 is installed on the upper left side of the U-shaped frame 11, and an inclined plate 35 is slidably mounted on the upper left side of the U-shaped frame 11. The telescopic end of the pushing cylinder 34 is connected to the inclined plate 35. An auxiliary rod 321 is installed on the upper left side of the diversion plate 32, and an inclined surface is provided on the left side of the inclined plate 35 to push the two diversion plates 32 corresponding to the opening of the converging plate 31 away from each other. By extending the telescopic rod of the pushing cylinder 34, the inclined plate 35 is moved to the left, so that the inclined plate 35 and the inclined surface of the auxiliary rod 321 cooperate, thereby causing the two diversion plates 32 corresponding to the opening of the converging plate 31 to swing away from each other to the maximum angle, thus allowing the accumulated and blocked ore to pass smoothly.

[0042] See Figure 1 , Figure 9 and Figure 10The unloading component 4 includes an L-shaped frame 41 installed at the rear of the conveyor belt 1. The horizontal section of the L-shaped frame 41 is located on the upper side of the conveyor belt 1. Several sets of unloading rollers 42 are rotatably arranged on the lower part of the horizontal section of the L-shaped frame 41 along the transmission direction of the conveyor belt 1. The spacing between each set of unloading rollers 42 gradually decreases from right to left. The unloading rollers 42 in the same set are gradually inclined to the left front. The number of unloading rollers 42 in the same set gradually increases and the spacing gradually decreases from right to left. A spiral lever 421 is provided on the outer side of the unloading rollers 42. The lower end of the unloading rollers 42 is arc-shaped and fits against the upper side of the conveyor belt 1. The upper sides of each set of unloading rollers 42 are connected to each other by a belt. An actuator motor 43 is installed on the upper front side of the L-shaped frame 41. The output shaft of the actuator motor 43 is connected to each set of unloading rollers by a belt. 42 Connection; When the conveyor belt 1 moves the ore to the feeding roller 42, the actuator motor 43 is started, simultaneously driving all the feeding rollers 42 to rotate synchronously. The ore contacts the feeding roller 42, causing the feeding roller 42 to push the ore to the left and forward to the outside of the conveyor belt 1 through the lever 421, thereby completing the feeding of the ore. Moreover, through multiple sets of feeding rollers 42, larger ore can be fed first, allowing smaller ore to pass through the gap of the set of feeding rollers 42 on the right, thereby avoiding the accumulation and blockage of ore at the feeding roller 42 and increasing the feeding efficiency. In addition, when the feeding roller 42 rotates, the spiral lever 421 can lift the ore upward, preventing the ore from sinking into the soil, thereby speeding up the movement of the ore and ensuring the efficiency of feeding.

[0043] The present invention includes the following steps when screening and desliming ore: First, the mud-stone mixture is placed on the conveyor belt 1, and then the conveyor belt 1 is started to convey the mud-stone mixture to the left. The rotating motor 25 is started to drive the two rotating frames 21 to rotate in the opposite direction of the conveyor belt 1, so that the rotating frames 21 scoop the mud-stone mixture into their interior. The mud-stone mixture is confined inside the rotating frames 21 by the unidirectional rotation of the rotating plate 22 and the cooperation of the comb plate 23. Then, the rotating shaking plate 24 is pushed back and forth by the pusher plate 242, so that the shaking plate 24 drives the mud-stone mixture to shake back and forth through the slots opened on it, breaking up the clumps of mud, so that the mud leaks out from the gap between the rotating plate 22 and the comb plate 23 onto the conveyor belt 1. Then, the pusher 233 pushes the pusher plate 232 to the rear, so that the comb plate 23 rotates to a vertical position under the action of gravity, thereby opening the side of the rotating frame 21, so that the ore falls on the upper side of the mud.

[0044] In the second step, when the ore falls onto the top of the soil, the conveyor belt 1 moves the ore to the converging plate 31. The converging plate 31 divides the ore into pairs through the opening structure. Then, the conveyor belt 1 moves the ore along the converging plate 31 to the diversion plate 32. The diversion plate 32 brushes the surface of the moving ore with cleaning bristles 33.

[0045] The third step involves starting the actuator motor 43, which simultaneously drives all the feeding rollers 42 to rotate synchronously. The ore comes into contact with the feeding rollers 42, causing the feeding rollers 42 to push the ore to the left and forward to the outside of the conveyor belt 1 via the lever 421, thus completing the feeding of the ore. Furthermore, the multiple sets of feeding rollers 42 allow for the feeding of larger ore first, while smaller ore passes through the gaps in the set of feeding rollers 42 on the right side, thereby preventing the ore from accumulating and clogging at the feeding rollers 42 and increasing the feeding efficiency. In addition, when the feeding rollers 42 rotate, the spiral lever 421 can lift the ore upwards, preventing the ore from sinking into the mud, thereby speeding up the movement of the ore and ensuring the efficiency of feeding.

[0046] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
