Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slag treatment, in particular to a slag removal machine. BACKGROUND

[0002] Various unwanted solid, liquid and gaseous waste will be produced in the mining process, which includes tailings, slag, waste rock, wastewater and waste gas. These excavated waste will pollute the environment, in order to solve the problem of environmental pollution caused by mining, the excavated waste produced by mining needs to be harmlessly treated, and the large particle slag, small particle slag and wastewater in the excavated waste need to be separated by the slag removal machine and then treated respectively.

[0003] The conventional slag removal machine separates the large particle slag from the small particle slag and the slurry in the excavated waste by vibration and screening, however, the small particle slag and the slurry may be coagulated and adhered to the inside of the machine body and the large particle slag, the hardened small particle slag and the slurry may scratch and collide with each part of the machine body, causing damage to the machine body of the slag removal machine, and blocking the screen holes of the slag removal machine, affecting the normal operation of the slag removal, affecting the normal use and slag removal effect of the slag removal machine. CONTENT OF THE INVENTION

[0004] The purpose of the present application is to solve the above problems, provide a slag removal machine which can stably and normally operate and has good slag removal effect, so that the above problems are improved.

[0005] The present application is realized by the following technical scheme:

[0006] The present application provides a slag removal machine, which comprises a screen plate, a guide plate, a machine body, a first ultrasonic wave generating assembly and an anti-adhesion device; the screen plate is used for separating large particle slag, small particle slag and slurry in excavated waste, the screen plate is inclinedly arranged, and the screen plate is provided with a protective edge parallel to both sides of the length direction of the screen plate; the guide plate is used for receiving small particle slag and slurry passing through the screen plate, the guide plate is inclinedly arranged synchronously with the screen plate, and the guide plate is provided with a protective edge parallel to both sides of the length direction of the guide plate; the machine body is used for driving the screen plate and the guide plate to vibrate; the first ultrasonic wave generating assembly is arranged on the machine body and used for emitting ultrasonic waves to the screen plate; the anti-adhesion device comprises a second ultrasonic wave generating assembly, the second ultrasonic wave generating assembly is arranged on the machine body and used for emitting ultrasonic waves to the guide plate; wherein the guide plate is lower than the screen plate and faces the screen plate, and the second ultrasonic wave generating assembly is arranged between the screen plate and the guide plate.

[0007] In the technical scheme of the embodiment of the present application, the excavated waste is put into the higher end of the inclined sieve plate, and the excavated waste moves along the inclined surface of the sieve plate under the action of gravity. The excavated waste sieve 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 sieve plate during the movement, and the large-particle slag continues to move along the sieve plate. The flow guide plate is used to receive the small-particle slag and slurry passing through the sieve plate. The slurry and small-particle slag passing through the sieve plate mostly fall into the higher end of the flow guide plate, and then continue to move along the inclined surface of the flow guide plate under the action of gravity. Since the small-particle slag and slurry may have moved a distance along the sieve plate before passing through the sieve plate, the small-particle slag and slurry falling onto the flow guide plate have a motion trend or initial speed in the same direction as the inclination direction of the sieve plate. The flow guide plate is inclined synchronously with the sieve plate, so that the small-particle slag and slurry falling onto the flow guide plate can move on the flow guide plate according to the motion trend or initial speed they already have, thereby reducing the time of the small-particle slag and slurry staying in the local area of the flow guide plate and reducing the risk of the small-particle slag and slurry adhering to the flow guide plate. The first ultrasonic wave generating assembly is arranged in the machine body and used to emit ultrasonic waves to the sieve plate. After the excavated waste on the sieve plate receives the ultrasonic waves, the slurry and small-particle slag start to vibrate at a high frequency, so that the slurry adhering to the large-particle slag or the sieve plate can be quickly separated from the large-particle slag or the sieve plate and fall into the flow guide plate through the sieve plate. The materials in the mud block formed by the small-particle slag and slurry in the excavated waste also vibrate and disperse into the original small-particle slag and slurry under the influence of the ultrasonic waves, and then pass through the sieve plate more quickly, thereby improving the effect of separating the large-particle slag, small-particle slag and slurry by the sieve plate. The anti-adhesion device includes a second ultrasonic wave generating assembly arranged in the machine body and used to emit ultrasonic waves to the flow guide plate. After the slurry and small-particle slag on the flow guide plate are affected by the ultrasonic waves from the second ultrasonic wave generating assembly, they start to vibrate at a high frequency. During the movement along the flow guide plate, the slurry and small-particle slag can continuously vibrate at different frequencies relative to the flow guide plate, so that the small-particle slag and slurry are not easy to adhere to the flow guide plate, thereby reducing the risk that the slurry and small-particle slag adhere to the flow guide plate and harden to block the normal movement of other slurry and small-particle slag and cause the flow guide plate to collide with other components and be damaged and difficult to clean. The deslagging machine provided in the embodiment of the present application can accelerate the deslagging efficiency, strengthen the deslagging effect, and reduce the risk that the slurry and small-particle slag adhere to the inside of the deslagging machine to affect the normal operation of the deslagging machine, affect the service life of the deslagging machine and be difficult to clean.

[0008] In some embodiments, the second ultrasonic wave generating assembly comprises an ultrasonic wave generator and two groups of ultrasonic wave transducers, the ultrasonic wave generator emits ultrasonic waves to the guide plate through the ultrasonic wave transducers, each group of ultrasonic wave transducers comprises a plurality of ultrasonic wave transducers, the plurality of ultrasonic wave transducers in one group of ultrasonic wave transducers are arranged at intervals along the length direction of the guide plate, and the two groups of ultrasonic wave transducers are respectively opposite to two sides of the guide plate parallel to the length direction of the guide plate.

[0009] In the technical scheme of the embodiments, the plurality of ultrasonic wave transducers in one group of ultrasonic wave transducers are arranged at intervals along the length direction of the guide plate, so that the pulp and small particle slag at all positions on the guide plate can be continuously affected by the ultrasonic waves, thereby reducing the risk of adhesion of the pulp and small particle slag to the guide plate at all positions. The pulp and small particle slag falling on the guide plate are mostly concentrated at the center of the guide plate, and the amount of the pulp and small particle slag near the two sides of the guide plate parallel to the length direction of the guide plate is small. The part with more pulp and small particle slag is subjected to stronger gravity, so the pulp and small particle slag at the center of the guide plate are more likely to flow along the guide plate and flow faster. Therefore, the pulp and small particle slag are not easy to adhere to the guide plate. The two groups of ultrasonic wave transducers are respectively opposite to the two sides of the guide plate parallel to the length direction of the guide plate, so that more ultrasonic waves can be emitted to the part of the pulp and small particle slag on the two sides of the guide plate, which has poor flowability and slow flow speed, thereby reducing the risk of adhesion of the small particle slag and the pulp to the guide plate. By controlling the action direction of the ultrasonic wave transducers to control the action range of the ultrasonic waves, the risk of adhesion of the small particle slag and the pulp to the guide plate is reduced in the part of the small particle slag and the pulp that is more likely to adhere to the guide plate. The amount of the pulp affected by the ultrasonic waves is reduced, thereby reducing the influence of the negative effects (a large number of micro-bubbles appear in the pulp, resulting in increased flow resistance and enhanced viscosity of the pulp) of the ultrasonic waves on the pulp on the flow process of the pulp on the guide plate or the subsequent processing.

[0010] In some embodiments, the higher end of the screen plate is further provided with a guide plate extending along the length direction of the screen plate, the guide plate has a receiving surface for receiving the excavated waste, and the receiving surface and the surface of the screen plate in contact with the excavated waste are smoothly transitioned.

[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 flow smoothly to the screen plate and then continue to move. On the one hand, the guide plate is provided 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-particle 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-particle slag can be dispersed through the screen holes, reducing the risk of slurry and small-particle slag concentrating on 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 includes a plurality of blades and a lifting assembly, which are arranged on the guide plate, and 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 blade to rise and fall along the thickness direction of the guide plate so that the cutting edge of the blade 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, due to the ultrasonic wave, a large number of bubbles 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. 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 cutting edge of the blade 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 point to flow upward, and the baffle The blade tip cuts the slurry, causing a cross-section at the part 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 burst. The bubbles near the cross-section will 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 reach the cross-section, they are driven upward by the blade and the slurry until they come into contact with the outside air and burst, 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 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 embodiments 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 cuts the ore pulp, the inclined surface of the blade portion can provide a larger upward thrust to the ore pulp around the cross section, thereby more easily causing the ore pulp to flow upward and facilitating the upward pushing of the bubbles in the ore pulp around the cross section.

[0016] In some embodiments, the deflector plate has a first edge, the first edge being located at a higher end of the deflector plate, and the first edge exceeding the projection of the blade on the deflector plate.

[0017] In the technical solution of the embodiments of the present application, the amount of ore pulp and small-particle slag falling through the screen plate and onto the deflector plate gradually decreases from the higher end of the deflector plate to the lower end of the deflector plate, wherein the amount of ore pulp and small-particle slag received closest to the higher end of the deflector plate is the largest, the first edge is located at the higher end of the deflector plate, and the first edge exceeds the projection of the blade on the deflector plate. In the length direction of the deflector plate, the gap between the first edge and the blade is opposite the position where the deflector plate receives the largest amount of ore pulp and small-particle slag, thereby avoiding the risk of damage to the blade caused by the impact of a large amount of small-particle ore pulp and prolonging the service life of the blade.

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

[0019] In the technical solution of the embodiments of the present application, the end of the blade facing the first edge is a tip-shaped structure, so that when the ore pulp falling into the gap between the first edge and the blade flows along the length direction of the deflector plate, the flow surface facing the blade can be cut by the blade to form a fragment to release the bubbles inside, thereby reducing the number of bubbles in the ore pulp and improving the flow speed and reducing the viscosity of the ore pulp.

[0020] In some embodiments, a plurality of flow dividing members are provided on the deflector plate, the flow dividing members protruding from the surface of the deflector plate in contact with the ore pulp, the flow dividing members exceeding the liquid level of the ore pulp on the deflector plate, the plurality of flow dividing members being arranged in the width direction of the deflector plate, and the plurality of flow dividing members being staggered with the plurality of blades.

[0021] The technical scheme of the embodiment of the present application is characterized in that a plurality of flow distribution members are arranged on the flow guide plate, the plurality of flow distribution members are arranged at intervals along the width direction of the flow guide plate, the plurality of flow distribution members are arranged alternately with the plurality of blades, the flow distribution member divides the ore pulp into a plurality of streams, and taking one stream between any two adjacent flow distribution members as an example, the ore pulp in the stream is cut off by the blade and pushed to flow upward, and then the ore pulp flowing to the liquid surface continues to flow away from the blade, and then is blocked by the flow distribution member and flows downward again, the ore pulp forms a swirling flow between the blade and the flow distribution member with the length direction of the flow guide plate as the center, and then the ore pulp at the lower part or even the bottom is lifted to the liquid surface, so that more bubbles can contact with the external air and break, and the removal effect of the bubbles in the ore pulp is improved.

[0022] In some embodiments, the flow distribution member is in the shape of a blade tip towards the higher end of the flow guide plate.

[0023] The technical scheme of the embodiment of the present application is characterized in that the flow distribution member is in the shape of a blade tip towards the higher end of the flow guide plate, when the ore pulp flows along the length direction of the flow guide plate and contacts the flow distribution member, the flow surface of the flow distribution member towards the flow distribution member can be cut off by the flow distribution member to release the bubbles inside, reduce the number of bubbles in the ore pulp, and improve the flow speed of the ore pulp and reduce the viscosity of the ore pulp.

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

[0025] The technical scheme of the embodiment of the present application is characterized in that the flow distribution member includes a plurality of flow distribution segments, and the plurality of flow distribution segments are arranged at intervals along the length direction of the flow guide plate, so that the ore pulp close to the flow distribution segment can flow through the gap between adjacent flow distribution segments, and the risk of the ore pulp deposited towards the flow distribution member and adhered to the flow distribution member is reduced.

[0041] According to some embodiments of the present application, optionally, as shown in Figures 1-6 As shown in the present application, a slag removal machine is provided, which includes a screen plate 1, a guide plate 2, a machine body 3, a first ultrasonic wave generating assembly 4 and an anti-sticking device 5. The screen plate 1 is used to separate large-particle slag, small-particle slag and ore slurry in excavated waste. The screen plate 1 is arranged obliquely, and the two sides of the screen plate 1 parallel to the length direction of the screen plate 1 are provided with edge guards. The guide plate 2 is used to receive small-particle slag and ore slurry passing through the screen plate 1. The guide plate 2 is obliquely arranged synchronously with the screen plate 1, and the two sides of the guide plate 2 parallel to the length direction of the guide plate 2 are provided with edge guards. The machine body 3 is used to drive the screen plate 1 and the guide plate 2 to vibrate. The first ultrasonic wave generating assembly 4 is arranged on the machine body 3 and used to emit ultrasonic waves to the screen plate 1. The anti-sticking device 5 includes a second ultrasonic wave generating assembly 50, which is arranged on the machine body 3 and used to emit ultrasonic waves to the guide plate 2. Wherein, the guide plate 2 is lower than the screen plate 1 and faces the screen plate 1, and the second ultrasonic wave generating assembly 50 is arranged between the screen plate 1 and the guide plate 2.

[0042] A plurality of screen holes are arranged on the screen plate 1, and the small-particle slag and the ore slurry can fall into the guide plate 2 through the screen holes on the screen plate 1.

[0043] The two sides of the screen plate 1 parallel to the length direction of the screen plate 1 are provided with edge guards, which prevent the large-particle slag from falling into the guide plate 10 from the edge of the screen plate 1. On the one hand, it prevents the large-particle slag from mixing into the ore slurry and the small-particle slag on the guide plate 2, and on the other hand, it prevents the large-particle slag from damaging the guide plate 2.

[0044] The two sides of the sieve plate 1 and the flow guide plate 2 can be arranged inside the shell of the machine body 3, so that the slag and the ore pulp on the sieve plate 1 and the flow guide plate 2 are prevented from being thrown out due to vibration and polluting the environment.

[0045] The projection of the sieve plate 1 on the flow guide plate 2 does not exceed the edge of the flow guide plate 2, so that the small-particle slag and the ore pulp passing through the sieve plate 1 can easily fall on the flow guide plate 2.

[0046] The flow guide plate 2 is provided with a guard edge parallel to the two sides in the length direction of the flow guide plate 2, so that the small-particle slag and the ore pulp are prevented from falling into the shell of the machine body 3 from the edge of the flow guide plate 2 and polluting the machine body 3 or falling out of the machine body 3 and polluting the external environment.

[0047] Ultrasonic wave is a kind of mechanical wave with extremely short wavelength, generally shorter than 2 cm in air. The short wavelength of ultrasonic wave is more likely to obtain anisotropic acoustic energy, which can be used for cleaning, stone crushing, sterilization and disinfection, etc. It has many applications in medicine and industry.

[0048] The excavated waste is put into the higher end of the inclined sieve plate 1, and the excavated waste moves along the inclined surface of the sieve plate 1 under the action of gravity. The excavated waste sieve 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 fall through the sieve holes on the sieve plate 1 during movement, and the large-particle slag continues to move along the sieve plate 1. The flow guide plate 2 is used to receive the small-particle slag and slurry passing through the sieve plate 1. The slurry and small-particle slag passing through the sieve plate 1 mostly fall into the higher end of the flow guide plate 2, and then continue to move along the inclined surface of the flow guide plate 2 under the action of gravity. Since the small-particle slag and slurry may have moved a distance along the sieve plate 1 before passing through the sieve plate 1, the small-particle slag and slurry falling onto the flow guide plate 2 have a motion trend or initial speed in the same direction as the inclination direction of the sieve plate 1. The flow guide plate 2 is inclined synchronously with the sieve plate 1, so that the small-particle slag and slurry falling onto the flow guide plate 2 can start to move on the flow guide plate 2 quickly according to the motion trend or initial speed they already have, reduce the time of the small-particle slag and slurry staying in the local area of the flow guide plate 2, and reduce the risk of the small-particle slag and slurry adhering to the flow guide plate 2. The first ultrasonic wave generating assembly 4 is arranged in the machine body 3 and used to emit ultrasonic waves to the sieve plate 1. After the excavated waste on the sieve plate 1 receives the ultrasonic waves, the slurry and small-particle slag start to vibrate at a high frequency, so that the slurry adhering to the large-particle slag or the sieve plate 1 can be quickly separated from the large-particle slag or the sieve plate 1 and smoothly fall into the flow guide plate 2 through the sieve plate 1. The substances in the mud block formed by the small-particle slag and slurry in the excavated waste also vibrate and disperse into the original small-particle slag and slurry under the influence of the ultrasonic waves, and then pass through the sieve plate 1 more quickly, thereby improving the effect of separating the large-particle slag, small-particle slag and slurry by the sieve plate 1. The anti-adhesion device 5 includes a second ultrasonic wave generating assembly 50 arranged in the machine body 3 and used to emit ultrasonic waves to the flow guide plate 2. After the slurry and small-particle slag on the flow guide plate 2 are affected by the ultrasonic waves from the second ultrasonic wave generating assembly 50, they start to vibrate at a high frequency. During the movement along the flow guide plate 2, the slurry and small-particle slag can continuously vibrate relative to the flow guide plate 2 at different vibration frequencies, so that the small-particle slag and slurry are not easy to adhere to the flow guide plate 2, thereby reducing the risk that the hardened slurry and small-particle slag adhering to the flow guide plate 2 block the normal movement of other slurry and small-particle slag, collide with other components to damage the flow guide plate 2, and are difficult to clean. The deslagging machine provided in the embodiments of the present application can accelerate the deslagging efficiency, strengthen the deslagging effect, and reduce the risk that the slurry and small-particle slag adhere to the inside of the deslagging machine to affect the normal operation of the deslagging machine, affect the service life of the deslagging machine, and are difficult to clean.

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

[0050] The ultrasonic wave generating assembly comprises the ultrasonic wave generator 500 and the ultrasonic wave transducers 501.

[0051] The ultrasonic wave generator 500, commonly known as ultrasonic wave electric box or ultrasonic wave power supply, its function is to convert electrical energy into high-frequency alternating current signals matching the ultrasonic wave transducers 501.

[0052] The function of the ultrasonic wave transducers 501 is to convert the input electrical power into mechanical power (i.e. ultrasonic waves) and then transmit them, while consuming very little power itself.

[0053] The plurality of ultrasonic wave transducers 501 in each group of ultrasonic wave transducers 501 are arranged at intervals along the length direction of the guide plate 2, so that the pulp and small particle slag at all places on the guide plate 2 can be continuously affected by ultrasonic waves, thereby reducing the risk of adhesion of the pulp and small particle slag to the guide plate 2; most of the pulp and small particle slag falling on the guide plate 2 are concentrated in the center of the guide plate 2, and the amount of pulp and small particle slag near the two sides of the guide plate 2 parallel to the length direction of the guide plate 2 is less, while the part with more pulp and small particle slag is subjected to stronger gravity, so the pulp and small particle slag located in the center of the guide plate 2 are more likely to flow along the guide plate 2 and flow faster, and thus are less likely to adhere to the guide plate 2, the two groups of ultrasonic wave transducers 501 are respectively opposite to the two sides of the guide plate 2 parallel to the length direction of the guide plate 2, which can emit more ultrasonic waves to the part of the pulp and small particle slag located on the two sides of the guide plate 2, which has poor flowability and slow flow speed, thereby reducing the risk of adhesion of this part of small particle slag and pulp to the guide plate 2, by controlling the direction of the ultrasonic wave transducers 501 to control the range of the ultrasonic waves, the risk of adhesion of the small particle slag and pulp more likely to adhere to the guide plate 2 to the guide plate 2 is reduced in a targeted manner, the amount of pulp affected by the ultrasonic waves is reduced, thereby weakening the negative effects (letting a large number of tiny bubbles appear in the pulp, causing the flow resistance of the pulp to increase and the viscosity to strengthen) of the ultrasonic waves on the pulp on the flow process of the pulp on the guide plate 2 or the subsequent processing.

[0054] According to some embodiments of the present application, as shown in Figure 1 、 Figures 5-6 Fig. 1, the higher end of the screen plate 1 is also provided with a guide plate 10 extending along the length direction of the screen plate 1, and the guide plate 10 has an accommodating surface 100 for accommodating the excavated waste, and the accommodating surface 100 and the surface of the screen plate 1 in contact with the excavated waste are smoothly connected.

[0055] The side of the guide plate 10 away from the screen plate 1 can be provided with a protective plate to prevent the excavated waste from falling off.

[0056] The included angle between the guide plate 10 and the horizontal direction can be greater than the included 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 an accommodating surface 100 for accommodating the excavated waste, and the excavated waste first falls onto the guide plate 10 and then starts to accelerate along the guide plate 10 under the action of gravity, and the accommodating surface 100 and the surface of the screen plate 1 in contact with the excavated waste are smoothly connected, 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 allows the waste entering the screen plate 1 to have a certain initial speed, so that the excavated waste is not easily stopped by the screen holes on the screen plate 1; on the other hand, the pulp and small particle slag can not all pass through the screen plate 1 when they first contact the screen holes on the screen plate 1 under the action of the initial speed, but can pass through the screen plate 1 after moving a distance under the combined action of gravity and the screen holes, so that the pulp and small particle slag can be dispersed to pass through the screen holes, reducing the risk of screen hole plugging or affecting the normal movement of other excavated waste caused by the concentrated accumulation of pulp and small particle slag at the screen holes in the local area.

[0058] According to some embodiments of the present application, as shown in Figure 2 、 Figure 4 and Figure 6 , the anti-sticking device 5 further comprises 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 in the width direction of the guide plate 2, and the connection between the blade 51 and the lifting assembly 52 is lower than the liquid level of the pulp on the guide plate 2; the lifting assembly 52 drives the blade 51 to ascend or descend in the thickness direction of the guide plate 2 so that the blade edge part of the blade 51 is above or below the liquid level of the pulp on the guide plate 2.

[0059] The main component of the ore slurry is liquid. When the ultrasonic wave propagates in the liquid, it will generate rapidly alternating compression and rarefaction (negative pressure) regions. In the compression region, the liquid molecules are compressed, while in the rarefaction region, the distance between the liquid molecules increases, generating negative pressure. If the strength of the negative pressure region is high enough, it will overcome the cohesion of the liquid, causing the formation of microcavities or bubbles in the liquid. In the ore slurry, these cavities or bubbles (also known as cavitation bubbles) will form, grow rapidly and periodically shrink and expand under the action of high-frequency ultrasonic waves. Cavitation bubbles increase in the rarefaction phase (low pressure) and are compressed or even collapsed in the compression phase (high pressure).

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

[0061] Due to the ultrasonic wave, a large number of bubbles appear inside the ore slurry, and a large number of bubbles form diffusion resistance in the liquid, limiting the free flow of the ore slurry and increasing the flow resistance. These bubbles interact with solid particles, making the ore slurry exhibit higher viscosity. The increase in flow resistance will cause the flow rate of the ore slurry to slow down, and the increase in viscosity will increase the probability of the ore slurry sticking to the guide plate 2. In order to solve the problem caused by a large number of bubbles in the ore slurry, the present application provides a blade 51 on the guide plate 2, and the connection between the blade 51 and the lifting assembly 52 is lower than the liquid level of the ore slurry on the guide plate 2; the lifting assembly 52 drives the blade 51 to rise and fall along the thickness direction of the guide plate 2, so that the cutting edge of the blade 51 protrudes above or below the liquid level of the ore slurry on the guide plate 2. When the blade 51 rises, it will drive the cut-off ore slurry to flow upward, and the blade tip will cut off the ore slurry, causing the ore slurry to form a fracture surface at the cut-off position. The bubbles at the fracture surface will be pierced by the blade 51 and then adhere to the surface of the blade 51, and then move upward under the push of the blade 51 and the ore slurry until they come into contact with the external air and break. The bubbles near the fracture surface will move towards the direction of lower pressure (i.e. the direction of the fracture surface) under the push of the internal pressure of the liquid, and then be driven upward by the blade 51 and the ore slurry until they come into contact with the external air and break. Thus, the number of bubbles in the ore slurry is reduced, the flowability of the ore slurry is improved, the viscosity of the ore slurry is reduced, the flow speed of the ore slurry is increased, and the risk of the ore slurry sticking to the guide plate 2 is reduced.

[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] The blade portion of the blade 51 does not exceed the liquid level of the ore pulp on the deflector 2 when cutting the ore pulp.

[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 the slope of the blade portion can provide a larger upward thrust to the ore pulp around the cross section when cutting the ore pulp, thereby more easily causing the ore pulp to flow upward and facilitating the upward pushing of the bubbles in the ore pulp around the cross section.

[0065] According to some embodiments of the present application, as shown in Figure 4 and Figure 6 The deflector 2 has a first edge 20 located at the higher end of the deflector 2, and the first edge 20 exceeds the projection of the blade 51 on the deflector 2.

[0066] The amount of ore pulp and small particle slag falling through the screen plate 1 and onto the deflector 2 decreases from the higher end of the deflector 2 to the lower end of the deflector 2, wherein the amount of ore pulp and small particle slag received closest to the higher end of the deflector 2 is the largest, the first edge 20 is located at the higher end of the deflector 2, the first edge 20 exceeds the projection of the blade 51 on the deflector 2, and in the length direction of the deflector 2, the gap between the first edge 20 and the blade 51 is opposite the position where the deflector 2 receives the largest amount of ore pulp and small particle slag, thereby avoiding the risk of damage to the blade 51 caused by the impact of a large amount of small particle ore pulp and prolonging the service life of the blade 51.

[0067] According to some embodiments of the present application, as shown in Figure 4 and Figure 6 The end of the blade 51 towards the first edge 20 is a tip-shaped structure.

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

[0069] The end of the blade 51 towards the first edge 20 is a tip-shaped structure, so that when the ore pulp falling into the gap between the first edge 20 and the blade 51 flows along the length direction of the deflector 2, the flow surface towards the blade 51 can be cut by the blade 51 to form a fragment to release the bubbles inside, thereby reducing the number of bubbles in the ore pulp and improving the flow speed and reducing the viscosity of the ore pulp.

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

[0071] The top surface of the flow distributor 21 can be an arc surface, so that the slurry can flow down along the top surface of the flow distributor 21, reducing the risk of hardening of the slurry remaining on the top surface of the flow distributor 21 and increasing the difficulty of cleaning.

[0072] The guide plate 2 is provided with a plurality of flow distributors 21, the plurality of flow distributors 21 are arranged along the width direction of the guide plate 2, the plurality of flow distributors 21 are staggered with the plurality of blades 51, the flow distributor 21 divides the slurry into a plurality of streams, taking any two adjacent flow distributors 21 as an example, the blade 51 rises to cut off the stream of slurry and pushes the slurry to flow upward, and then the slurry flowing to the liquid level continues to flow away from the blade 51, and then is blocked by the flow distributor 21 and flows downward again. The slurry forms a swirling flow between the blade 51 and the flow distributor 21, which is centered on the length direction of the guide plate 2, thereby lifting the slurry at the lower part or even the bottom to the liquid level, so that more bubbles can contact with the external air and break, 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 flow distributor 21 towards the higher end of the guide plate 2 is a blade tip structure.

[0074] The flow distributor 21 towards the higher end of the guide plate 2 is a blade tip structure, when the slurry flows along the length direction of the guide plate 2 to contact the flow distributor 21, the flow surface towards the flow distributor 21 can be cut off by the flow distributor 21 to release the bubbles inside, thereby reducing the number of bubbles in the slurry and improving 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 distributor 21 includes a plurality of flow distribution sections 210, and the plurality of flow distribution sections 210 are arranged along the length direction of the guide plate 2.

[0076] The flow distributor 21 includes a plurality of flow distribution sections 210, and the plurality of flow distribution sections 210 are arranged along the length direction of the guide plate 2, so that the slurry close to the flow distribution section 210 can flow through the gap between adjacent flow distribution sections 210, thereby reducing the risk of the slurry deposited towards the flow distributor 21 adhering to the flow distributor 21.

[0077] Although the present application has been described with reference to preferred embodiments, various modifications can be made to the application without departing from the scope of the application. In particular, the technical features mentioned in the various embodiments can be combined in any way, provided that there is no structural conflict. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
