Description

Technical Field

[0001] The present application relates to the technical field of slag processing, and in particular to a slag remover. Background Art

[0002] The mining process will produce various unwanted solid, liquid and gaseous wastes, including tailings, slag, waste rock, waste water and waste gas. These mining wastes will pollute the environment. In order to solve the problem of environmental pollution caused by mining, it is necessary to treat the mining wastes generated by mining harmlessly, and the large particles of slag, small particles of slag and waste water in the mining waste need to be separated by a slag remover and then treated separately.

[0003] Conventional slag removers separate large-particle slag from small-particle slag and slurry in excavated waste by vibration and screening. However, the small-particle slag and slurry may clump and adhere to the inside of the machine body and the large-particle slag. The hardened small-particle slag and slurry may scratch and collide with various parts of the machine body, causing damage to the slag remover body and blocking the sieve holes of the slag remover, affecting the normal operation of the slag remover and affecting the normal use of the slag remover and the slag removal effect. Summary of the invention

[0004] The purpose of the present application is to provide a slag remover to address the above-mentioned problems, which can operate stably and normally and has a good slag removal effect, so as to improve the above-mentioned problems.

[0005] This application is achieved through the following technical solutions:

[0006] The present application provides a slag remover, which includes a sieve plate, a guide plate, a body, a first ultrasonic generating assembly and an anti-sticking device; the sieve plate is used to separate large-particle slag, small-particle slag and slurry in excavated waste, and the sieve plate is arranged at an angle; the guide plate is used to receive small-particle slag and slurry passing through the sieve plate, and the guide plate and the sieve plate are inclined synchronously; the body is used to drive the sieve plate and the guide plate to vibrate; the first ultrasonic generating assembly is arranged on the body, and is used to emit ultrasonic waves to the sieve plate; the anti-sticking device includes a second ultrasonic generating assembly, and the second ultrasonic generating assembly is arranged on the body, and is used to emit ultrasonic waves to the guide plate; wherein the guide plate is lower than the sieve plate and is opposite to the sieve plate, the first ultrasonic generating assembly is opposite to the surface of the sieve plate in contact with the excavated waste, and the second ultrasonic generating assembly is arranged between the sieve plate and the guide plate.

[0007] In the technical solution of the embodiment of the present application, the excavated waste is put into the higher end of the inclined screen plate, so that the excavated waste moves along the inclined surface of the screen plate under the action of gravity. The excavated waste screen plate is used to separate large-particle slag, small-particle slag and slurry in the excavated waste. The slurry and small-particle slag can fall through the sieve holes on the screen plate during the movement, while the large-particle slag continues to move along the screen plate; the guide plate is used to receive the small-particle slag and slurry that pass through the screen plate. The slurry and small-particle slag that pass through the screen plate mostly fall on the higher end of the guide plate, and then continue to move along the inclined surface of the guide plate under the action of gravity. Since the small-particle slag and slurry pass through the screen plate The small particles of slag and the machine body may have moved along the screen plate for a distance before, resulting in the small particles of slag and the machine body falling onto the guide plate having a movement trend or initial velocity in the same direction as the inclination direction of the screen plate. The guide plate and the screen plate are inclined synchronously, so that the small particles of slag and slurry can start to move on the guide plate according to the movement trend or initial velocity of this part after falling onto the guide plate, thereby reducing the time that the small particles of slag and slurry stay in the local area on the guide plate and reducing the risk of small particles of slag and slurry sticking to the guide plate. The first ultrasonic generating component is arranged on the machine body, and is used to emit ultrasonic waves to the screen plate. After the excavated waste on the screen plate receives the ultrasonic waves, the slurry and small particles of slag begin to move at high frequency. The vibration allows the pulp attached to the large particles of slag or the screen plate to be separated from the large particles of slag or the screen plate more quickly, and smoothly pass through the screen plate and fall into the guide plate. The materials in the mud blocks formed by the agglomeration of multiple small particles of slag and pulp in the excavated waste, which are large in size and difficult to pass through the screen plate, will also vibrate with each other under the influence of the ultrasonic wave and disperse into the original small particles of slag and pulp, and then pass through the screen plate more quickly, thereby improving the effect of the screen plate in separating large particles of slag from small particles of slag and pulp; the anti-sticking device includes a second ultrasonic generating component, which is arranged on the machine body and is used to emit ultrasonic waves to the guide plate. The pulp and small particles of slag on the guide plate are affected by the second ultrasonic wave. The wave generating component starts high-frequency vibration after the ultrasonic action, so that the slurry and small-particle slag can continuously vibrate relative to the guide plate at different frequencies while moving along the guide plate, making it difficult for the small-particle slag and slurry to stick to the guide plate, reducing the risk of the slurry and small-particle slag sticking to the guide plate and hardening, blocking the normal movement of other slurries and small-particle slag, colliding with other components to damage the guide plate, and making cleaning more difficult; the slag remover provided in the embodiment of the present application can speed up the slag removal efficiency, enhance the slag removal effect, and reduce the risk of the slag and small-particle slag sticking to the inside of the slag remover, affecting the normal operation of the slag removal, affecting the service life of the slag remover, and making cleaning more difficult.

[0008] In some embodiments, the second ultrasonic generating component includes an ultrasonic generator and two groups of ultrasonic transducers. The ultrasonic generator emits ultrasonic waves to the guide plate through the ultrasonic transducers. Each group of ultrasonic transducers includes multiple ultrasonic transducers. The multiple ultrasonic transducers in a group of ultrasonic transducers are arranged at intervals along the length direction of the guide plate. The two groups of ultrasonic transducers are respectively facing the two sides of the guide plate parallel to their own length direction; the number of multiple ultrasonic transducers contained in any one group of the two groups of ultrasonic transducers is the same as the number of multiple ultrasonic transducers contained in the other group of ultrasonic transducers.

[0009] In the technical solution of the embodiment of the present application, multiple ultrasonic transducers in a group of ultrasonic transducers are arranged at intervals along the length direction of the guide plate, so that the slurry and small particles of slag at various locations on the guide plate can be continuously affected by ultrasonic waves, thereby reducing the risk of the slurry and small particles of slag sticking to various locations of the guide plate; most of the slurry and small particles of slag that fall onto the guide plate are concentrated in the center of the guide plate, and the amount of slurry and small particles of slag in the areas on both sides of the guide plate parallel to its own length direction is small, while the part with more slurry and small particles of slag is subject to stronger gravity. Therefore, the slurry and small particles of slag located in the center of the guide plate are more likely to flow along the guide plate and have a faster flow speed, so they are not easy to stick to the guide plate. The two groups of ultrasonic transducers The ultrasonic transducers are respectively facing the two sides of the guide plate parallel to the length direction of the guide plate, and can emit more ultrasonic waves to the slurry and small particles of slag with poor fluidity and slow flow speed on both sides of the guide plate, thereby reducing the risk of these small particles of slag and slurry adhering to the guide plate. By controlling the action direction of the ultrasonic transducer to control the action range of the ultrasonic wave, the risk of some small particles of slag and slurry that are more likely to adhere to the guide plate and adhere to the guide plate is reduced in a targeted manner, and the amount of slurry affected by the ultrasonic wave is reduced, thereby reducing the negative effect of the ultrasonic wave on the slurry (causing a large number of tiny bubbles to appear inside the slurry, resulting in increased flow resistance and enhanced viscosity of the slurry) on the flow process of the slurry on the guide plate or subsequent treatment.

[0010] In some embodiments, a guide plate extending along the length direction of the screen plate is further provided at the higher end of the screen plate, the guide plate having a receiving surface for receiving excavated waste, and the receiving surface and the contact surface of the screen plate with the excavated waste have a smooth transition.

[0011] In the technical solution of the embodiment of the present application, the guide plate has a receiving surface for receiving the excavated waste. The excavated waste first falls onto the guide plate, and then begins to accelerate along the guide plate under the action of gravity. The receiving surface and the surface of the screen plate in contact with the excavated waste have a smooth transition, so that the excavated waste on the guide plate can smoothly flow to the screen plate and then continue to move. The guide plate is provided on the one hand so that the waste entering the screen plate can have a certain initial speed, so that the excavated waste is not easily blocked by the screen holes and stops moving on the screen plate; on the other hand, the slurry and small particles of slag will not all pass through the screen plate when they just come into contact with the screen holes on the screen plate under the action of the initial speed, but will pass through the screen plate under the combined action of gravity and the screen holes after moving a certain distance, so that the slurry and small particles of slag can disperse through the screen holes, reducing the risk of slurry and small particles of slag being concentrated in the screen holes in a local area, causing the screen holes to be blocked or affecting the normal movement of other excavated waste.

[0012] In some embodiments, the anti-sticking device further comprises a plurality of blades and a lifting assembly, wherein the blades and the lifting assembly are arranged on the guide plate, wherein the plurality of blades are arranged at intervals along the width direction of the guide plate, and the connection between the blades and the lifting assembly is lower than the liquid level of the slurry on the guide plate; the lifting assembly drives the blades to rise and fall along the thickness direction of the guide plate so that the cutting edge portion of the blades exceeds the liquid level of the slurry on the guide plate or is lower than the liquid level of the slurry on the guide plate.

[0013] In the technical solution of the embodiment of the present application, a large number of bubbles appear inside the slurry due to ultrasound. The large number of bubbles form diffusion resistance in the liquid, which restricts the free flow of the slurry and increases the flow resistance. These bubbles interact with the solid particles, causing the slurry to exhibit higher viscosity. The increase in flow resistance will cause the flow rate of the slurry to slow down, and the increase in viscosity increases the probability of the slurry adhering to the guide plate. In order to solve the problem caused by a large number of bubbles in the slurry, the present application sets a blade on the guide plate, and the connection between the blade and the lifting component is lower than the liquid level of the slurry on the guide plate; the lifting component drives the blade to rise and fall along the thickness direction of the guide plate so that the blade edge part exceeds the liquid level of the slurry on the guide plate or is lower than the liquid level of the slurry on the guide plate. When the blade rises, it will drive the slurry at the cut-off point to flow upward, and the baffle The blade tip cuts the slurry, causing a cross section at the location where the slurry is cut by the blade. The bubbles at the cross section are punctured by the blade and adhere to the surface of the blade. Then, they move upward under the push of the blade and the slurry until they come into contact with the outside air and rupture. The bubbles close to the cross section move toward the direction of weaker pressure (i.e., the direction of the cross section) under the push of the internal pressure of the liquid. When they move to the cross section, they are driven upward by the blade and the slurry until they come into contact with the outside air and rupture, thereby reducing the number of bubbles in the slurry, improving the fluidity of the slurry, reducing the viscosity of the slurry, accelerating the flow rate of the slurry, and reducing the risk of the slurry sticking to the guide plate.

[0014] In some embodiments, the thickness of the blade edge portion of the blade gradually increases from the tip of the blade to the connection between the blade and the lifting assembly.

[0015] In the technical solution of the embodiment of the present application, the thickness of the blade portion of the blade gradually increases from the tip of the blade to the connection between the blade and the lifting assembly, so that when the tip of the blade cuts the slurry, the inclined surface of the blade portion can provide a greater upward thrust for the slurry around the section, thereby making it easier to cause the slurry to flow upward, and facilitate pushing the bubbles in the slurry around the section upward.

[0016] In some embodiments, the guide plate has a first edge, the first edge is located at a higher end of the guide plate, and the first edge exceeds a projection of the blade on the guide plate.

[0017] In the technical solution of the embodiment of the present application, the amount of slurry and small-particle slag that pass through the screen plate and fall onto the guide plate decreases gradually from the higher end of the guide plate to the lower end of the guide plate, wherein the end closest to the higher end of the guide plate receives the most slurry and small-particle slag. The first side is located at the higher end of the guide plate, and the first side exceeds the projection of the blade on the guide plate. In the length direction of the guide plate, the gap between the first side and the blade is opposite to the position where the guide plate receives the most slurry and small-particle slag, thereby avoiding the risk of the blade being damaged by being hit by a large amount of small-particle slurry, thereby extending the service life of the blade.

[0018] In some embodiments, an end of the blade facing the first edge is a tip-shaped structure.

[0019] In the technical solution of the embodiment of the present application, the end of the blade facing the first edge is a tip-like structure, so that when the slurry that falls into the gap between the first edge and the blade flows along the length direction of the guide plate, the flow surface facing the blade can be cut off by the blade to form fragments to release the bubbles inside, thereby reducing the number of bubbles in the slurry, increasing the flow speed of the slurry and reducing the viscosity of the slurry.

[0020] In some embodiments, a plurality of diverters are provided on the guide plate, the diverters protrude from the surface of the guide plate in contact with the slurry, the diverters exceed the liquid level of the slurry on the guide plate, the plurality of diverters are arranged at intervals along the width direction of the guide plate, and the plurality of diverters are staggered with the plurality of blades.

[0021] In the technical solution of the embodiment of the present application, a plurality of diverter pieces are arranged on the guide plate, and the plurality of diverter pieces are arranged at intervals along the width direction of the guide plate. The plurality of diverter pieces and the plurality of blades are staggered, and the diverter pieces divide the slurry into multiple strands. Taking a strand of slurry between any two adjacent diverter pieces as an example, after the blade rises and cuts off the slurry and pushes the slurry to flow upward, the slurry flowing to the liquid surface will continue to flow in the direction away from the blade, and then be blocked by the diverter piece and flow downward again. The slurry forms a swirling flow between the blade and the diverter piece with the length direction of the guide plate as the center, thereby turning up the slurry located at the lower part or even the bottom to the liquid surface, so that more bubbles can contact and burst with the outside air, thereby improving the removal effect of the bubbles in the slurry.

[0022] In some embodiments, the higher end of the flow divider facing the guide plate is a knife-tip structure.

[0023] In the technical solution of the embodiment of the present application, the higher end of the diverter facing the guide plate is a knife-tip structure. When the slurry flows along the length direction of the guide plate until it contacts the diverter, the flow surface toward the diverter can be cut off by the diverter to form fragments to release the bubbles inside, thereby reducing the number of bubbles in the slurry, increasing the flow speed of the slurry and reducing the viscosity of the slurry.

[0024] In some embodiments, the flow divider includes a plurality of flow divider segments, and the plurality of flow divider segments are arranged at intervals along the length direction of the guide plate.

[0025] In the technical solution of the embodiment of the present application, the diverter element includes a plurality of diverter sections, which are arranged at intervals along the length direction of the guide plate so that the slurry close to the diverter section can flow through the gaps between adjacent diverter sections, thereby reducing the risk of the slurry adhering to the diverter element after being deposited toward the diverter element.

[0041] According to some embodiments of the present application, optionally, Figure 1 to Figure 6 As shown, the present application provides a slag remover, which includes a sieve plate 1, a guide plate 2, a body 3, a first ultrasonic generating assembly 4 and an anti-sticking device 5; the sieve plate 1 is used to separate large-particle slag, small-particle slag and slurry in excavated waste, and the sieve plate 1 is arranged at an angle; the guide plate 2 is used to receive small-particle slag and slurry passing through the sieve plate 1, and the guide plate 2 is inclined synchronously with the sieve plate 1; the body 3 is used to drive the sieve plate 1 and the guide plate 2 to vibrate; the first ultrasonic generating assembly 4 is arranged on the body 3, and is used to emit ultrasonic waves to the sieve plate 1; the anti-sticking device 5 includes a second ultrasonic generating assembly 50, and the second ultrasonic generating assembly 50 is arranged on the body 3, and is used to emit ultrasonic waves to the guide plate 2; wherein the guide plate 2 is lower than the sieve plate 1 and is directly opposite to the sieve plate 1, the first ultrasonic generating assembly 4 is directly opposite to the surface of the sieve plate 1 in contact with the excavated waste, and the second ultrasonic generating assembly 50 is arranged between the sieve plate 1 and the guide plate 2.

[0042] The screen plate 1 is provided with a plurality of screen holes, and small particles of slag and slurry can pass through the screen holes on the screen plate 1 and fall into the guide plate 2 .

[0043] The screen plate 1 is provided with edge guards on both sides parallel to its own length direction to prevent large particles of slag from falling from the edge of the screen plate 1 into the guide plate 10. On the one hand, it prevents large particles of slag from mixing into the slurry and small particles of slag on the guide plate 2, and on the other hand, it prevents large particles of slag from damaging the guide plate 2.

[0044] Both sides of the screen plate 1 and the guide plate 2 can be arranged on the inner side of the shell of the machine body 3 to prevent the slag and slurry on the screen plate 1 and the guide plate 2 from being thrown out and polluting the environment due to vibration.

[0045] The projection of the screen plate 1 on the guide plate 2 does not exceed the edge of the guide plate 2, so that small particles of slag and slurry passing through the screen plate 1 can fall onto the guide plate 2 more easily.

[0046] The guide plate 2 is provided with edge guards on both sides parallel to its length direction to prevent small particles of slag and slurry from falling from the edge of the guide plate 2 into the inner side of the shell of the machine body 3 to pollute the machine body 3 or falling out of the machine body 3 to pollute the external environment.

[0047] Ultrasonic waves are a type of mechanical wave with a very short wavelength, which is generally shorter than 2 cm in the air. The short wavelength of ultrasonic waves makes it easier to obtain anisotropic sound energy, which can be used for cleaning, stone crushing, sterilization, etc. It has many applications in medicine and industry.

[0048] The excavated waste is put onto the higher end of the inclined screen plate 1, and the excavated waste moves along the inclined surface of the screen plate 1 under the action of gravity. The excavated waste screen plate 1 is used to separate large-particle slag, small-particle slag and slurry in the excavated waste. The slurry and small-particle slag can pass through the sieve holes on the screen plate 1 during the movement, while the large-particle slag continues to move along the screen plate 1; the guide plate 2 is used to receive the small-particle slag and slurry passing through the screen plate 1. The slurry and small-particle slag passing through the screen plate 1 mostly fall on the higher end of the guide plate 2, and then continue to move along the inclined surface of the guide plate 2 under the action of gravity. Since the small-particle slag and slurry may have fallen along the screen plate before passing through the screen plate 1, the guide plate 2 is used to receive the small-particle slag and slurry passing through the screen plate 1. The slurry and small-particle slag passing through the screen plate 1 mostly fall on the higher end of the guide plate 2, and then continue to move along the inclined surface of the guide plate 2 under the action of gravity. 1 moves a certain distance, so that the small particles of slag and the machine body 3 falling on the guide plate 2 have a movement trend or initial speed in the same direction as the inclination direction of the screen plate 1. The guide plate 2 is inclined synchronously with the screen plate 1, so that the small particles of slag and slurry can start to move on the guide plate 2 according to the movement trend or initial speed of this part after falling on the guide plate 2, thereby reducing the time that the small particles of slag and slurry stay in the local area on the guide plate 2, and reducing the risk of the small particles of slag and slurry adhering to the guide plate 2; the first ultrasonic generating component 4 is arranged on the machine body 3, and is used to emit ultrasonic waves to the screen plate 1. After the excavated waste on the screen plate 1 receives the ultrasonic waves, the slurry and the small particles of slag begin to vibrate at a high frequency, so that The slurry attached to the large-particle slag or the screen plate 1 can be separated from the large-particle slag or the screen plate 1 relatively quickly, and smoothly pass through the screen plate 1 and fall into the guide plate 2. The materials in the mud blocks formed by the agglomeration of multiple small-particle slag and slurry in the excavated waste and which are large in size and difficult to pass through the screen plate 1 will also vibrate with each other under the influence of the ultrasonic wave and disperse into the original small-particle slag and slurry, and then pass through the screen plate 1 relatively quickly, thereby improving the effect of the screen plate 1 in separating the large-particle slag from the small-particle slag and slurry; the anti-sticking device 5 includes a second ultrasonic wave generating component 50, which is arranged on the body 3 and is used to emit ultrasonic waves to the guide plate 2, and the slurry and small-particle slag on the guide plate 2 are affected by the second ultrasonic wave. The ultrasonic generating component 50 starts high-frequency vibration after the ultrasonic wave is acted upon, so that the slurry and small-particle slag can continuously vibrate relative to the guide plate 2 at different vibration frequencies while moving along the guide plate 2, so that the small-particle slag and slurry are not easily adhered to the guide plate 2, and the risk of the slurry and small-particle slag adhering to the guide plate 2 and hardening to block the normal movement of other slurries and small-particle slag, colliding with other components to damage the guide plate 2, and making cleaning more difficult is reduced; the slag remover provided in the embodiment of the present application can speed up the slag removal efficiency, enhance the slag removal effect, and reduce the risk of the slurry and small-particle slag adhering to the inside of the slag remover, affecting the normal operation of the slag removal, affecting the service life of the slag remover, and making cleaning more difficult.

[0049] According to some embodiments of the present application, optionally, Figure 2 and Figure 6As shown, the second ultrasonic generating component 50 includes an ultrasonic generator 500 and two groups of ultrasonic transducers 501. The ultrasonic generator 500 emits ultrasonic waves to the guide plate 2 through the ultrasonic transducers 501. Each group of ultrasonic transducers 501 includes multiple ultrasonic transducers 501. The multiple ultrasonic transducers 501 in a group of ultrasonic transducers 501 are arranged at intervals along the length direction of the guide plate 2. The two groups of ultrasonic transducers 501 are respectively facing the two sides of the guide plate 2 parallel to their own length direction; the number of multiple ultrasonic transducers 501 contained in any one group of ultrasonic transducers 501 in the two groups of ultrasonic transducers 501 is the same as the number of multiple ultrasonic transducers 501 contained in the other group of ultrasonic transducers 501.

[0050] The ultrasonic generating component includes an ultrasonic generator 500 and an ultrasonic transducer 501 .

[0051] The ultrasonic generator 500 , usually called an ultrasonic generator or an ultrasonic power supply, converts electrical energy into a high-frequency alternating current signal that matches the ultrasonic transducer 501 .

[0052] The function of the ultrasonic transducer 501 is to convert the input electrical power into mechanical power (ie ultrasonic wave) and then transmit it out, while consuming a very small part of the power itself.

[0053] Multiple ultrasonic transducers 501 in a group of ultrasonic transducers 501 are arranged at intervals along the length direction of the guide plate 2, so that the slurry and small particles of slag at various locations on the guide plate 2 can be continuously affected by ultrasonic waves, thereby reducing the risk of the slurry and small particles of slag sticking to various locations of the guide plate 2; most of the slurry and small particles of slag that fall onto the guide plate 2 are concentrated in the center of the guide plate 2, and the amount of slurry and small particles of slag in the areas on both sides of the guide plate 2 parallel to its own length direction is small, and the part with more slurry and small particles of slag is subject to stronger gravity. Therefore, the slurry and small particles of slag located at the center of the guide plate 2 are more likely to flow along the guide plate 2 and have a faster flow speed, so they are not easy to stick to the guide plate 2. The two groups of ultrasonic transducers 501 are respectively arranged at intervals along the length direction of the guide plate 2, so that the slurry and small particles of slag at the center of the guide plate 2 are more likely to flow along the guide plate 2 and have a faster flow speed, so they are not easy to stick to the guide plate 2. The ultrasonic wave is directed toward the two sides of the guide plate 2 parallel to its length direction, so that more ultrasonic waves can be emitted to the slurry and small-particle slag with poor fluidity and slow flow speed on both sides of the guide plate 2, thereby reducing the risk of these small-particle slag and slurry adhering to the guide plate 2. By controlling the action direction of the ultrasonic transducer 501 to control the action range of the ultrasonic wave, the risk of some small-particle slag and slurry that are more likely to adhere to the guide plate 2 and adhere to the guide plate 2 is reduced in a targeted manner, and the amount of slurry affected by the ultrasonic wave is reduced, thereby reducing the negative effect of the ultrasonic wave on the slurry (causing a large number of tiny bubbles to appear inside the slurry, resulting in increased flow resistance and enhanced viscosity of the slurry) on the flow process of the slurry on the guide plate 2 or subsequent treatment.

[0054] According to some embodiments of the present application, optionally, Figure 1 , Figure 5-6 As shown, a guide plate 10 extending along the length direction of the screen plate 1 is also provided at the higher end of the screen plate 1. The guide plate 10 has a receiving surface 100 for receiving excavated waste. The receiving surface 100 and the surface of the screen plate 1 in contact with the excavated waste have a smooth transition.

[0055] A guard plate may be provided on the side of the guide plate 10 facing away from the screen plate 1 to prevent excavated waste from falling.

[0056] The angle between the guide plate 10 and the horizontal direction may be greater than the angle between the screen plate 1 and the horizontal direction, so that the excavated waste falling onto the guide plate 10 can have a greater acceleration.

[0057] The guide plate 10 has a receiving surface 100 for receiving the excavated waste. The excavated waste first falls onto the guide plate 10, and then begins to accelerate along the guide plate 10 under the action of gravity. The receiving surface 100 and the surface of the screen plate 1 in contact with the excavated waste have a smooth transition, so that the excavated waste on the guide plate 10 can smoothly flow to the screen plate 1 and then continue to move. The guide plate 10 is provided so that on the one hand, the waste entering the screen plate 1 can have a certain initial speed, so that the excavated waste is not easily blocked by the screen holes and stops moving on the screen plate 1; on the other hand, the slurry and small particles of slag will not all pass through the screen plate 1 when they just come into contact with the screen holes on the screen plate 1 under the action of the initial speed, but will pass through the screen plate 1 under the combined action of gravity and the screen holes after moving a certain distance, so that the slurry and small particles of slag can disperse through the screen holes, reducing the risk of slurry and small particles of slag being concentrated in the screen holes in a local area, causing the screen holes to be blocked or affecting the normal movement of other excavated waste.

[0058] According to some embodiments of the present application, optionally, as 1- Figure 2 , Figure 4 and Figure 6 As shown, the anti-sticking device 5 also includes a plurality of blades 51 and a lifting assembly 52. ​​The blades 51 and the lifting assembly 52 are arranged on the guide plate 2. The plurality of blades 51 are arranged at intervals along the width direction of the guide plate 2. The connection between the blades 51 and the lifting assembly 52 is lower than the liquid level of the slurry on the guide plate 2. The lifting assembly 52 drives the blades 51 to rise and fall along the thickness direction of the guide plate 2 so that the cutting edge of the blades 51 exceeds the liquid level of the slurry on the guide plate 2 or is lower than the liquid level of the slurry on the guide plate 2.

[0059] The main component of the slurry is liquid. When ultrasound propagates in the liquid, it will produce rapidly alternating compression and rarefaction (negative pressure) areas. In the compression area, the liquid molecules are compressed, while in the rarefaction area, the distance between the liquid molecules increases, generating negative pressure. If the intensity of the negative pressure area is high enough, it will overcome the cohesive force of the liquid, causing tiny cavities or bubbles to form in the liquid. In the slurry, these cavities or bubbles (also called cavitation bubbles) will form and grow rapidly and periodically shrink and expand under the action of high-frequency ultrasound. Cavitation bubbles will increase in the rarefaction stage (low pressure) and will be compressed or even collapsed in the compression stage (high pressure).

[0060] Under the continuous action of ultrasonic vibration, the cavitation effect will produce a large number of tiny bubbles, which form a "suspension" in the liquid. In the slurry, these bubbles will affect the overall flow characteristics of the slurry. The presence of bubbles changes the local density and viscosity of the slurry. As small obstacles, bubbles increase the fluid resistance of the slurry, causing the slurry to encounter more resistance when passing through the vibrating screen, affecting fluidity. This effect is particularly obvious when the bubble concentration is high, which will cause the slurry to exhibit higher viscosity or "pseudoplastic" characteristics.

[0061] Because the ultrasound waves cause a large number of bubbles to appear inside the slurry, a large number of bubbles form diffusion resistance in the liquid, which restricts the free flow of the slurry and increases the flow resistance. These bubbles interact with the solid particles, causing the slurry to exhibit higher viscosity. The increase in flow resistance will cause the flow rate of the slurry to slow down, and the increase in viscosity increases the probability of the slurry adhering to the guide plate 2. In order to solve the problem caused by a large number of bubbles in the slurry, the present application sets a blade 51 on the guide plate 2, and the connection between the blade 51 and the lifting component 52 is lower than the liquid level of the slurry on the guide plate 2; the lifting component 52 drives the blade 51 to rise and fall along the thickness direction of the guide plate 2 so that the blade 51 exceeds the liquid level of the slurry on the guide plate 2 or is lower than the liquid level of the slurry on the guide plate 2. When the blade 51 rises, it will drive the slurry at the cut-off point to flow upward. The blade tip of the baffle cuts off the slurry, causing a section to appear at the part where the slurry is cut by the blade 51. After the bubbles at the section are punctured by the blade 51, they will adhere to the surface of the blade 51 and then move upward under the push of the blade 51 and the slurry until they come into contact with the outside air and rupture. The bubbles close to the section will move in the direction of weaker pressure (i.e., the direction of the section) under the push of the internal pressure of the liquid, and move to the section and be driven upward by the blade 51 and the slurry until they come into contact with the outside air and rupture, thereby reducing the number of bubbles in the slurry, improving the fluidity of the slurry, reducing the viscosity of the slurry, accelerating the flow rate of the slurry, and reducing the risk of the slurry adhering to the guide plate 2.

[0062] According to some embodiments of the present application, optionally, Figure 2As shown, the thickness of the blade portion of the blade 51 gradually increases from the tip of the blade 51 to the connection between the blade 51 and the lifting assembly 52 .

[0063] When cutting the ore pulp, the blade portion of the blade 51 will not completely exceed the liquid level of the ore pulp on the guide plate 2 .

[0064] The thickness of the blade portion of the blade 51 gradually increases from the tip of the blade 51 to the connection between the blade 51 and the lifting assembly 52, so that when the tip of the blade cuts the slurry, the inclined surface of the blade portion can provide a greater upward thrust for the slurry around the section, thereby making it easier to cause the slurry to flow upward, and facilitate pushing the bubbles in the slurry around the section upward.

[0065] According to some embodiments of the present application, optionally, Figure 4 and Figure 6 As shown, the guide plate 2 has a first edge 20 , and the first edge 20 is located at a higher end of the guide plate 2 , and the first edge 20 exceeds the projection of the blade 51 on the guide plate 2 .

[0066] The amount of slurry and small-particle slag that pass through the screen plate 1 and fall onto the guide plate 2 decreases gradually from the higher end of the guide plate 2 to the lower end of the guide plate 2, wherein the end closest to the higher end of the guide plate 2 receives the most slurry and small-particle slag. The first edge 20 is located at the higher end of the guide plate 2, and the first edge 20 exceeds the projection of the blade 51 on the guide plate 2. In the length direction of the guide plate 2, the gap between the first edge 20 and the blade 51 is opposite to the position where the guide plate 2 receives the most slurry and small-particle slag, thereby avoiding the risk of the blade 51 being damaged by being hit by a large amount of small-particle slurry, thereby extending the service life of the blade 51.

[0067] According to some embodiments of the present application, optionally, Figure 4 and Figure 6 As shown, one end of the blade 51 facing the first edge 20 is a blade tip structure.

[0068] The end of the blade 51 away from the first edge 20 may be a straight surface or a curved surface, thereby reducing the risk of the blade 51 scratching an operator or subsequent equipment.

[0069] The end of the blade 51 facing the first edge 20 is a blade-shaped structure, so that when the slurry that falls into the gap between the first edge 20 and the blade 51 flows along the length direction of the guide plate 2, the flow surface facing the blade 51 can be cut off by the blade 51 to form fragments to release the bubbles inside, thereby reducing the number of bubbles in the slurry, increasing the flow speed of the slurry and reducing the viscosity of the slurry.

[0070] According to some embodiments of the present application, optionally, Figure 1-2 , Figure 4 and Figure 6As shown, a plurality of diverter members 21 are provided on the guide plate 2, the diverter members 21 protrude from the surface of the guide plate 2 in contact with the slurry, the diverter members 21 exceed the liquid level of the slurry on the guide plate 2, the plurality of diverter members 21 are arranged at intervals along the width direction of the guide plate 2, and the plurality of diverter members 21 are staggered with the plurality of blades 51.

[0071] The top surface of the diverter 21 may be a curved surface, so that the slurry can flow down along the top surface of the diverter 21 , thereby reducing the risk of the slurry being retained on the top surface of the diverter 21 and hardening, which increases the difficulty of cleaning.

[0072] A plurality of diverter pieces 21 are provided on the guide plate 2, and the plurality of diverter pieces 21 are arranged at intervals along the width direction of the guide plate 2. The plurality of diverter pieces 21 and the plurality of blades 51 are staggered. The diverter pieces 21 divide the slurry into multiple strands. Taking a strand of slurry between any two adjacent diverter pieces 21 as an example, after the blade 51 rises to cut off the slurry and pushes the slurry to flow upward, the slurry flowing to the liquid surface will continue to flow in the direction away from the blade 51, and then be blocked by the diverter piece 21 and flow downward again. The slurry forms a swirling flow centered on the length direction of the guide plate 2 between the blade 51 and the diverter piece 21, and then the slurry located at the lower part or even the bottom is turned up to the liquid surface, so that more bubbles can contact with the outside air and burst, thereby improving the removal effect of the bubbles in the slurry.

[0073] According to some embodiments of the present application, optionally, Figure 4 As shown, the higher end of the flow divider 21 facing the guide plate 2 is a knife-tip structure.

[0074] The higher end of the diverter 21 facing the guide plate 2 is a knife-tip structure. When the slurry flows along the length direction of the guide plate 2 until it contacts the diverter 21, the flow surface toward the diverter 21 can be cut off by the diverter 21 to release the bubbles inside, thereby reducing the number of bubbles in the slurry, increasing the flow speed of the slurry and reducing the viscosity of the slurry.

[0075] According to some embodiments of the present application, optionally, Figure 4 and Figure 6 As shown, the flow divider 21 includes a plurality of flow divider sections 210 , and the plurality of flow divider sections 210 are arranged at intervals along the length direction of the guide plate 2 .

[0076] The diverter 21 includes a plurality of diverter sections 210, which are arranged at intervals along the length direction of the guide plate 2 so that the slurry close to the diverter sections 210 can flow through the gaps between adjacent diverter sections 210, thereby reducing the risk of the slurry adhering to the diverter 21 after being deposited toward the diverter 21.

[0077] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts.
