Description

Technical Field

[0001] The present invention relates to the technical field of ore dressing equipment, and more specifically, to a horizontal barrel type slag separation equipment. Background Art

[0002] In the production process of the mineral processing plant, the high gradient magnetic separator, weak magnetic separator and other equipment used have their appropriate feed particle size. If the feed particle size exceeds the particle size range, it will affect the production indicators and even damage the equipment. In the high gradient magnetic separation operation, the coarse-grained minerals in the slurry will be stuck between the magnetic medium bars of the magnetic medium box. As time accumulates, the residual minerals in the medium box will become more and more, and eventually the magnetic medium box will be blocked, making the magnetic medium box completely ineffective. In addition, the plastics present in the slurry will continue to circulate in the grinding and grading process, which will affect the grinding efficiency. Therefore, before performing operations such as high gradient magnetic separation or weak magnetic separators, slag separation equipment is usually installed to effectively isolate various coarse-grained minerals and plastics in the slurry.

[0003] In the prior art, the slag separation equipment commonly used in production sites mainly includes fixed screens, cylindrical screens and vibrating slag separation and screening devices, etc., so as to solve the influence of coarse-grained minerals on the separation process and equipment. Among them, if a fixed screen is used to separate coarse-grained minerals and plastics, although the device does not require additional power to drive, it is easy to clog the screen holes and must be cleaned frequently by humans; if a cylindrical screen or a vibrating slag separation and screening device is used to separate coarse-grained minerals and plastics, although the device does not require manual cleaning, it requires additional power to drive.

[0004] In summary, how to provide a slag separation device that does not require additional driving force and does not require manual cleaning is a problem that currently needs to be solved urgently by those skilled in the art. Summary of the invention

[0005] In view of this, the purpose of the present invention is to provide a horizontal cylinder slag separation equipment, which can effectively separate slag and materials without additional driving force, so it can effectively reduce energy consumption, and the device does not require manual cleaning, so it can effectively reduce labor costs. In addition, the device has a simple structure, is easy to use, has a good slag separation effect, and can be promoted for use.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] A horizontal drum type slag separation device, comprising: a screen drum device for screening slag, a feeding device for providing high-flow slurry, a slag discharge trough provided in the screen drum device for receiving slag with a particle size larger than the aperture of the screen hole, a ore receiving trough provided outside the screen drum device for receiving materials with a particle size smaller than the aperture of the screen hole, and supporting devices provided at both ends of the screen drum device for supporting the screen drum device, the screen drum device can rotate relative to the supporting device, and the outlet of the slag discharge trough is connected to the discharge port of the screen drum device;

[0008] A plurality of sieve holes are provided on the side of the screen drum device, and a special-shaped baffle is correspondingly provided on the inner peripheral wall of the side of the screen drum device. A radial structure can be formed between two adjacent special-shaped baffles so that the slag can fall when the slag is rotated to a high place. The feeding device is provided with a nozzle for spraying slurry, and the spraying direction of the nozzle is toward the special-shaped baffle, so that the kinetic energy of the high-speed slurry is converted into the kinetic energy of the rotation of the screen drum device.

[0009] Preferably, the screen drum device comprises a screen, and a first shell and a second shell respectively arranged at two ends of the screen for supporting the screen, and the first shell and the second shell are rotatable relative to the supporting device.

[0010] Preferably, the first shell and the second shell are both detachably connected to the screen.

[0011] Preferably, the supporting device includes a base and a bracket, the top of the base is provided with a first supporting member for supporting the first shell, the top of the bracket is provided with a second supporting member for supporting the second shell, and the first supporting member and the first shell, as well as the second supporting member and the second shell are both connected by bearings.

[0012] Preferably, the ore receiving trough includes an arc-shaped groove arranged around the outer periphery of the screen and a fixing member for supporting and fixing the position of the groove, the fixing member is connected to the groove, the groove matches the shape and size of the screen, and the highest point of the groove is higher than the highest point of the feeding device.

[0013] Preferably, the first shell is provided with a feed port, the second shell is provided with the discharge port, the feeding device is arranged in the screen, the feeding device comprises a first feeding pipe for communicating with the feed port to provide high-flow rate slurry, a second feeding pipe provided with the nozzle and arranged above the first feeding pipe, and a bent pipe for connecting the first feeding pipe and the second feeding pipe, the slag discharge trough is arranged below the second feeding pipe, and the slag discharge trough is communicated with the discharge port of the second shell.

[0014] Preferably, a side of the slag discharge chute close to the screen is parallel to the screen to fully collect the slag.

[0015] Preferably, a spray assembly for flushing the sieve holes is provided on the periphery of the sieve drum device, and the spray assembly includes a spray member with a plurality of nozzles arranged around the periphery of the sieve drum device and a conveying member for conveying water to the spray member, and the conveying member is connected to the spray member.

[0016] Preferably, the special-shaped baffle is a rhombus-shaped baffle.

[0017] Preferably, the screen cylinder device is a strip screen cylinder or a mesh screen cylinder, the body of the strip screen cylinder is composed of a plurality of rhombus-shaped baffles evenly arranged along the inner circumferential wall and parallel to each other, and the body of the mesh screen cylinder is composed of a plurality of rhombus-shaped baffles arranged along the inner circumferential wall and staggered to form a grid.

[0018] When using the horizontal drum slag separator provided by the present invention, since the feeding device can provide high-flow rate slurry, and the slurry can be sprayed through the nozzle of the feeding device, and since the spraying direction of the nozzle is toward the special-shaped baffle, when the slurry is sprayed onto the inner wall of the screen drum device, the slurry with high spraying speed will collide strongly with the special-shaped baffle. This process will cause the special-shaped baffle to be subjected to a large impact force, and the impact force can effectively drive the screen drum device to rotate, so that the high-flow rate slurry can be screened without the need for additional driving force, so as to effectively separate the slag and the material.

[0019] During the slurry injection process, after the slurry contacts the inner wall of the cylinder of the screen drum device, the ore particles with a particle size smaller than the sieve hole diameter can pass through the sieve hole and enter the ore receiving trough with the water flow. Among them, the ore particles with a particle size smaller than the sieve hole diameter rarely pass through the sieve hole directly during the injection process. More small ore particles pass through the sieve hole when they contact the inner surface of the screen and then enter the ore receiving trough, or small ore particles pass through the sieve hole and enter the ore receiving trough with the water flow.

[0020] However, slag with a particle size larger than the aperture of the sieve hole will never be able to pass through the sieve hole, and the slag will be stuck in the sieve hole. However, since a radial structure is formed between adjacent special-shaped baffles, that is, the distance between one end of two adjacent special-shaped baffles on the inner circumferential wall of the sieve drum device is smaller than the distance between one end of two adjacent special-shaped baffles away from the inner circumferential wall of the sieve drum device, therefore, when the sieve drum device rotates under the action of impact force, and when the slag stuck on the sieve hole is rotated to a higher position, the slag can be separated from the sieve hole under the action of gravity and fall into the slag discharge trough, and finally the slag will be discharged along the slag discharge trough.

[0021] The device can make full use of the kinetic energy of the slurry itself to realize the rotation of the screen drum device. It does not need additional driving force to ensure the normal operation of the slag separation equipment, which can effectively reduce energy consumption. In addition, the slag separation effect of the device is good, and it can effectively separate slag and materials, etc. In addition, the screen holes of the screen drum device of the device will not be blocked by slag, so there is no need for manual cleaning, which can effectively reduce labor costs.

[0022] To sum up, the horizontal cylinder slag separation equipment provided by the present invention can effectively separate slag and materials without additional driving force, so it can effectively reduce energy consumption, and the device does not require manual cleaning, so it can effectively reduce labor costs. In addition, the device has a simple structure, is easy to use, has a good slag separation effect, and can be promoted for use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The core of the present invention is to provide a horizontal cylinder slag separation equipment, which can effectively separate slag and materials without additional driving force, so it can effectively reduce energy consumption, and the device does not require manual cleaning, so it can effectively reduce labor costs. In addition, the device has a simple structure, is easy to use, has a good slag separation effect, and can be promoted for use.

[0033] Please refer to Figures 1 to 5 ,in, Figure 1 This is a schematic diagram of the structure of the horizontal drum type slag separation equipment provided by the present invention; Figure 2 It is a schematic diagram of the explosion of the horizontal drum type slag separation equipment; Figure 3 It is the right view of the horizontal drum type slag separation equipment; Figure 4 It is a structural schematic diagram of a strip screen drum; Figure 5 It is a structural schematic diagram of the grid screen cylinder.

[0034] The present specific embodiment provides a horizontal drum type slag separation equipment, comprising: a screen drum device for screening slag, a feeding device for providing high-velocity slurry, a slag discharge trough 8 arranged in the screen drum device for receiving slag with a particle size larger than the aperture of the screen hole, a ore receiving trough 13 arranged outside the screen drum device for receiving materials with a particle size smaller than the aperture of the screen hole, and supporting devices arranged at both ends of the screen drum device for supporting the screen drum device, the screen drum device can rotate relative to the supporting device, and the outlet of the slag discharge trough 8 is connected with the discharge port of the screen drum device; a plurality of sieve holes are arranged on the side of the screen drum device, and a special-shaped baffle 14 is correspondingly arranged on the inner peripheral wall of the side of the screen drum device, and a radial structure can be formed between two adjacent special-shaped baffles 14 so that the slag falls when rotating to a high place, and the feeding device is provided with a nozzle for spraying slurry, and the spraying direction of the nozzle is toward the special-shaped baffle 14, so that the kinetic energy of the high-speed slurry is converted into the kinetic energy of the rotation of the screen drum device.

[0035] It should be noted that materials with a particle size smaller than the sieve hole diameter may include useful materials such as mineral particles and water, while slag with a particle size larger than the sieve hole diameter refers to waste materials that need to be screened.

[0036] It should also be noted that a plurality of sieve holes are provided on the side of the screen drum device, and a special-shaped baffle 14 is correspondingly provided on the inner peripheral wall of the side of the screen drum device. A radial structure can be formed between two adjacent special-shaped baffles 14 to facilitate the slag to fall from a high place. It means that when the screen holes of the screen drum device are observed from the outside to the inside, a radial structure can be observed to be formed between the special-shaped baffles 14 arranged on the inner peripheral wall of the screen. The special-shaped baffles will not affect the size of the screen holes, but make the screen holes look like they radiate inward, so that if the slag stuck at the screen holes is rotated to a high place with the screen drum device, the slag can fall along the special-shaped baffle 14 due to the existence of the radial structure, thereby effectively avoiding the phenomenon of slag blocking the screen holes, and there is no need to manually clean the screen drum device, reducing labor costs and saving labor. Among them, the radial structure can be understood as the distance between one end of two adjacent special-shaped baffles 14 on the inner wall of the sieve hole is smaller than the distance between one end of two adjacent special-shaped baffles 14 away from the inner wall of the sieve hole, so that the slag stuck in the sieve hole can fall off freely at a high place.

[0037] In addition, the above-mentioned sieve holes can be set to rectangular, square, trapezoidal, diamond-shaped and other shapes, but it is necessary to provide a special-shaped baffle 14 on the inner periphery of the sieve hole so that a radial structure can be formed between two adjacent special-shaped baffles 14.

[0038] In actual use, the structure, size, shape, position, material, etc. of the screen drum device, feeding device, slag discharge chute 8, ore receiving chute 13 and supporting device can be determined according to actual conditions and actual needs.

[0039] When using the horizontal drum slag separator provided by the present invention, since the feeding device can provide high-flow rate slurry, and the slurry can be sprayed through the nozzle of the feeding device, and since the spraying direction of the nozzle is toward the special-shaped baffle 14, when the slurry is sprayed to the inner wall of the screen drum device, the slurry with high spraying speed will collide more strongly with the special-shaped baffle 14. This process will cause the special-shaped baffle 14 to be subjected to a large impact force, and the impact force can effectively drive the screen drum device to rotate, so that the high-flow rate slurry can be screened without the need for additional driving force.

[0040] During the slurry injection process, after the slurry contacts the inner peripheral wall of the cylinder of the screen drum device, the ore particles with a particle size smaller than the sieve hole diameter can pass through the sieve hole and enter the ore receiving trough 13 along with the water flow. Among them, the ore particles with a particle size smaller than the sieve hole diameter directly pass through the sieve hole less during the injection process, and more small ore particles pass through the sieve hole when they contact the inner surface of the screen and then enter the ore receiving trough 13, or small ore particles pass through the sieve hole along with the water flow and enter the ore receiving trough 13.

[0041] However, slag with a particle size larger than the aperture of the sieve hole will never be able to pass through the sieve hole, and the slag will be stuck in the sieve hole. However, since a radial structure is formed between adjacent special-shaped baffles 14, that is, the distance between one end of two adjacent special-shaped baffles 14 on the inner circumferential wall of the sieve drum device is smaller than the distance between one end of two adjacent special-shaped baffles 14 away from the inner circumferential wall of the sieve drum device, when the sieve drum device rotates under the action of impact force, and when the slag stuck on the sieve hole is rotated to a higher position, the slag can be separated from the sieve hole under the action of gravity and fall into the slag discharge trough 8, and finally the slag will be discharged along the slag discharge trough 8.

[0042] In addition, it should be noted that the feeding device here is used to provide high-velocity slurry, which may mean that the feeding device increases the flow rate of the high-velocity slurry again and then sprays the slurry with a higher flow rate toward the special-shaped baffle 14. When the slurry enters the current process from the previous process, the slurry has a high flow rate due to the height difference between the two process devices, and the feeding device can effectively increase the slurry flow rate by reducing the flow pipe of the high-velocity slurry.

[0043] The device can make full use of the kinetic energy of the slurry itself to realize the rotation of the screen drum device. It does not need additional driving force to ensure the normal operation of the slag separation equipment, which can effectively reduce energy consumption. In addition, the slag separation effect of the device is good, and it can effectively separate slag and materials, etc. In addition, the screen holes of the screen drum device of the device will not be blocked by slag, so there is no need for manual cleaning, which can effectively reduce labor costs.

[0044] To sum up, the horizontal cylinder slag separation equipment provided by the present invention can effectively separate slag without additional driving force, so it can effectively reduce energy consumption, and the device does not require manual cleaning, so it can effectively reduce labor costs. In addition, the device has a simple structure, is easy to use, has a good slag separation effect, and can be promoted for use.

[0045] On the basis of the above embodiment, preferably, the screen drum device comprises a screen 4, a first shell 3 and a second shell 10 respectively arranged at both ends of the screen 4 for supporting the screen 4, and the first shell 3 and the second shell 10 can rotate relative to the supporting device. Therefore, when the slurry is sprayed onto the special-shaped baffle 14 of the screen 4 and collides, the screen 4 will be pushed to rotate, and then the overall structure composed of the screen 4, the first shell 3 and the second shell 10 can rotate relative to the supporting device.

[0046] Preferably, the first housing 3 and the second housing 10 are both detachably connected to the screen 4. This facilitates installation of the feeding device and the slag discharge trough 8 inside the screen 4, and also facilitates subsequent equipment replacement and maintenance. If parts of the first housing 3, the second housing 10, or the screen 4 are damaged, the damaged parts can be replaced by disassembly, and then the new parts can be used in conjunction with other undamaged parts, which can effectively reduce maintenance costs and increase the service life of the device.

[0047] In actual use, the shape, size, structure, material, position, etc. of the first shell 3, the second shell 10 and the screen 4 can be determined according to actual conditions and actual needs.

[0048] Preferably, the supporting device includes a base 1 and a bracket 12, a first supporting member for supporting the first shell 3 is provided on the top of the base 1, a second supporting member for supporting the second shell 10 is provided on the top of the bracket 12, and the first supporting member and the first shell 3, and the second supporting member and the second shell 10 are all connected by bearings.

[0049] In this embodiment, a first bearing 2 may be interposed between the inner periphery of the first support member and the outer periphery of the first housing 3 , and a second bearing 11 may be interposed between the inner periphery of the second support member and the outer periphery of the second housing 10 .

[0050] In addition, it should be noted that the heights of the axis centers of the first support member and the second support member can be consistent, so that the axis centers of the feed port and the discharge port of the screen drum device are consistent, that is, the screen drum device can be placed horizontally.

[0051] In actual use, the structure, size, shape, position, etc. of the base 1 and the bracket 12 can be determined according to actual conditions and actual needs.

[0052] On the basis of the above embodiment, preferably, the ore receiving chute 13 includes an arc-shaped groove arranged around the outer periphery of the screen 4 and a fixing member for supporting and fixing the position of the groove, the fixing member is connected to the groove, the groove matches the shape and size of the screen 4, and the highest point of the groove is higher than the highest point of the feeding device.

[0053] In this embodiment, the groove matches the shape and size of the screen 4, and the groove is arranged around the outer periphery of the screen 4 so that the groove can fully collect the material passing through the screen hole, wherein the highest point of the groove is higher than the highest point of the feeding device, in order to prevent the material ejected from the screen hole by the feeding device from flying out directly without being collected in the groove.

[0054] During actual use, the shape, size, structure, position, etc. of the groove and the fixing parts can be determined according to actual conditions and actual needs to ensure that the groove can fully collect the materials flying out of the sieve holes.

[0055] Preferably, the first shell 3 is provided with a feed port, the second shell 10 is provided with a discharge port, the feeding device is arranged in the screen 4, the feeding device includes a first feeding pipe 5 for communicating with the feed port to provide high-flow slurry, a second feeding pipe 6 provided with a nozzle and arranged above the first feeding pipe 5, and a bent pipe 7 for connecting the first feeding pipe 5 and the second feeding pipe 6, and a slag discharge trough 8 is arranged below the second feeding pipe 6, and the slag discharge trough 8 is connected with the discharge port of the second shell 10.

[0056] It should be noted that the first feeding pipe 5 for providing high-flow slurry here may refer to the first feeding pipe 5 increasing the flow rate of the high-flow slurry again, and then conveying the slurry to the bending pipe 7 and the second feeding pipe 6, and finally spraying the slurry with a higher flow rate toward the special-shaped baffle 14. When the slurry enters this process from the previous process, the slurry has a high flow rate due to the height difference between the devices, and the first feeding pipe 5 has a smaller diameter than the previous slurry conveying pipeline, which is conducive to further increasing the slurry flow rate.

[0057] It should also be noted that the second feeding pipe 6 is arranged above the first feeding pipe 5 to facilitate the installation of the slag discharge trough 8. Moreover, raising the height of the second feeding pipe 6 provided with a nozzle is beneficial to increasing the gravitational potential energy of the slurry, so that the slurry, under the dual effects of its own kinetic energy and gravitational potential energy, is sprayed from a certain height along a parabola toward the special-shaped baffle 14 on the inner wall of the screen 4. This is beneficial to increasing the injection speed of the slurry, thereby increasing the collision force on the special-shaped baffle 14, and ultimately being more conducive to the rotation of the screen drum device and the slag separation operation.

[0058] Preferably, the slag trough 8 and the second feeding pipe 6 can be fixedly connected by a connecting rod 9. Arranging the feeding device and the slag trough in the screen 4 is conducive to making the device structure more compact, effectively reducing the device footprint, and avoiding space limitation problems.

[0059] It should also be noted that the collision force on the special-shaped baffle 14 can be decomposed into a parallel force parallel to the special-shaped baffle 14 for causing the slurry to fly out of the sieve hole and a vertical force perpendicular to the special-shaped baffle 14 for causing the screen drum device to rotate. Therefore, increasing the collision force on the special-shaped baffle 14 is conducive to the rotation of the screen drum device and the flying of slag out of the sieve hole. In addition, the device can realize the rotation of the screen drum device and the separation of slag without additional driving force, which can effectively reduce energy consumption.

[0060] Preferably, the side of the slag trough 8 close to the screen 4 is parallel to the screen 4 to fully collect the slag, which means that the distance between the side of the slag trough 8 close to the screen 4 and the side wall of the screen 4 is equal. In this way, when the slag rotates to a high place and falls freely, it can all fall into the slag trough 8. Therefore, the slag trough 8 can be set as close to and parallel to the screen 4 as possible, which is conducive to fully collecting the slag and avoiding the slag falling into the screen 4 and repeatedly wearing the screen 4.

[0061] Preferably, a spray assembly 15 for flushing the sieve holes is provided at the periphery of the sieve drum device. The spray assembly 15 includes a spray member with a plurality of nozzles arranged around the periphery of the sieve drum device and a conveying member for conveying water to the spray member, and the conveying member is connected to the spray member.

[0062] It should be noted that the spraying parts arranged on the outer periphery of the screen drum device will be more conducive to the slag stuck in the screen hole falling off, because the slag can be separated from the screen hole under the action of its own gravity and the impact force of the sprayed water, thereby effectively avoiding the occurrence of the screen hole blockage phenomenon, so as to ensure that the screen drum device effectively separates the slag. Therefore, when the slag with a particle size larger than the screen hole remains in the screen hole and rotates to a high position with the screen drum device, the slag can enter the slag discharge trough 8 under the flushing of the spraying assembly 15, and be discharged from the screen drum device with the water flow.

[0063] During actual use, the shape, size, structure, material, position, etc. of the spray parts and conveying parts can be determined according to actual conditions and actual needs.

[0064] On the basis of the above embodiment, preferably, the special-shaped baffle 14 is a rhombus-shaped baffle.

[0065] It should be noted that a rhombus-shaped baffle is provided inside the sieve hole, which will make the sieve hole observed from the outside to the inside, perpendicular to the screen surface, present a radial structure. This is not only conducive to flushing the slag in the sieve hole with flushing water, but can even allow the slag to fall freely from a high place without flushing water. Therefore, it will help reduce the occurrence of slag stuck in the mesh, and also reduce the degree of wear of the screen 4, which can effectively increase the service life of the screen 4, so that the screen 4 can maintain a high screening efficiency.

[0066] In addition to setting the special-shaped baffle 14 as a rhombus-shaped baffle, the structure, shape, size, etc. of the special-shaped baffle 14 can also be determined according to actual conditions and actual needs to ensure that adjacent special-shaped baffles 14 can form a radial structure.

[0067] Preferably, the screen cylinder device is a strip screen cylinder or a mesh screen cylinder, the body of the strip screen cylinder is composed of a plurality of rhombus-shaped baffles evenly arranged along the inner circumferential wall and parallel to each other, and the body of the mesh screen cylinder is composed of a plurality of rhombus-shaped baffles arranged along the inner circumferential wall and staggered to form a grid.

[0068] It should be noted that the strip screen cylinder here refers to a screen cylinder with a strip-shaped screen hole, and the grid screen cylinder refers to a screen cylinder with a grid-shaped screen hole. However, regardless of the shape of the screen hole, a rhombus-shaped baffle plate needs to be arranged on the inner periphery of the screen hole. For example, a strip screen cylinder can be formed by a plurality of rhombus-shaped baffle plates evenly arranged along the inner peripheral wall and parallel to each other to form a strip screen hole, or a grid screen cylinder can be formed by a plurality of rhombus-shaped baffle plates arranged along the inner peripheral wall and staggered to form a grid screen hole.

[0069] It should also be noted that the bar screen is not suitable for screening flaky slag, but it has a large discharge area, a large screen hole coverage rate, and a high screening efficiency, while the mesh screen is suitable for screening flaky slag. Therefore, in actual use, the type and size of the screen hole can be determined according to actual conditions and actual needs.

[0070] It should be noted that the first feeding pipe 5 and the second feeding pipe 6, the first shell 3 and the second shell 10, the first support member and the second support member, the first bearing 2 and the second bearing 11 mentioned in the present application document, wherein the first and the second are only for distinguishing the different positions, and there is no order of precedence.
