[0023] Based on the above structural features of the present application, the implementation methods of the present application are further described: Reference Figure 1-2 The present embodiment provides a slurry particle washing device, including a hydrocyclone separator 1, which includes a cyclone barrel 11, a feed pipe 12, a discharge pipe 13, an overflow pipe 14 and a connecting pipe 15; the feed pipe 12 is fixedly connected and communicated with the top of the cyclone barrel 11 (for example, fixedly connected by an integrated seal or fixedly connected by a welded seal); the upper part of the cyclone barrel 11 is in the shape of a straight cylinder with a fixed diameter, and the lower part is in the shape of an inverted cone, and the upper and lower parts of the cyclone barrel 11 are fixedly connected and communicated by an integrated seal; a top plate is provided on the top of the cyclone barrel 11, and the edge of the top plate is fixedly connected to the top edge of the cyclone barrel 11 by welding and sealing. The feed pipe 12 is horizontally arranged and tangent to the outer edge of the cyclone barrel 11, thereby realizing cyclone separation.

[0024] Reference Figure 1 to Figure 3The discharge pipe 13 is connected and communicated with the bottom of the cyclone 11 (for example, connected by an integrated seal or welded seal), and a first valve body 131 is installed in the middle of the discharge pipe 13. The feed pipe 12 is connected in series with the first liquid pump and the dilution funnel 19 in sequence through a hose, and the first liquid pump is used to press the slurry dilution liquid in the dilution funnel 19 into the cyclone 11. The dilution funnel 19 is in an inverted cone shape, and the bottom end of the dilution funnel 19 is higher than the top of the liquid pump and the top of the cyclone 11 to prevent the dilution liquid from flowing back and remaining.

[0025] Reference Figure 3 , a flushing nozzle 191 is arranged obliquely upward in the dilution funnel 19, and the flushing nozzle 191 is plugged and fixed to the side wall of the dilution funnel 19 (for example, a sealed and fixed connection is achieved by welding). When in use, grab the bottom of the side wall of the concentration pot 21 and turn it over, and put the concentration pot 21 obliquely on the flushing nozzle 191. Most of the slurry in the concentration pot 21 flows into the dilution funnel 19 when it is turned over; the slurry particles adhering to the inner wall of the concentration pot 21 flow into the dilution funnel 19 under the flushing of the flushing nozzle 191. The minimum diameter of the inner cavity of the concentration pot 21 is larger than the maximum diameter of the flushing nozzle 191, and the diameter difference is not less than 5 mm, so as to avoid splashing of slurry during flushing. The flushing nozzle 191 is connected and communicated with the pure water supply system; a first solenoid valve is provided on the flushing nozzle 191.

[0026] Reference Figure 3 and Figure 5 The side wall of the dilution funnel 19 near the bottom of the flushing nozzle 191 extends upward to form an upper side wall 190, and the upper side wall 190 is in the shape of an arc plate; since the concentration pot 21 is inclined and the opening is directed to the bottom of the flushing nozzle 191, it is easier for the slurry to splash along the radial direction of the flushing nozzle 191 (because when the slurry particles accumulate at the opening position of the dilution funnel 19, the gap available for liquid flow is reduced, and splashing is likely to occur). The upper side wall 190 is used to redirect the slurry splashing obliquely upward to the dilution funnel 19 to avoid the loss of slurry particles with the splashing slurry, thereby improving the accuracy of subsequent detection.

[0027] Reference Figure 3 and Figure 4, a reversible nozzle cleaning assembly 192 is provided above the dilution funnel 19; the nozzle cleaning assembly 192 includes a pad 1921, a flushing ring 1922, a water supply hose 1923 and a flip motor, one end of the water supply hose 1923 is connected and communicated with the flushing ring 1922 through a second solenoid valve, and the other end is connected and communicated with the pure water supply system. The end of the flushing ring 1922 is fixedly connected to the extension rod (for example, fixedly connected by bolts), and the extension rod is vertically fixedly connected to the rotating shaft (for example, fixedly connected by bolts); two pads 1921 are provided and are respectively arranged on both sides of the rotating shaft, and the two ends of the rotating shaft are respectively inserted into the inner ring position of the bearing in the mounting hole of the side wall of the pad 1921; the pad 1921 is fixedly connected to the support module 7 by bolts; the flip motor is fixedly connected to the support module 7 by bolts; the output shaft of the flip motor is coaxially fixedly connected to the rotating shaft (for example, fixedly connected by bolts), and the flip motor can drive the flushing ring 1922 to flip. Before the concentration pot 21 is upside down and mounted on the flushing nozzle 191, the flip motor can drive the flushing ring 1922 to flip outward to provide a holding space for the concentration pot 21; after the concentration pot 21 is removed, the flip motor can drive the flushing ring 1922 to flip until the flushing ring 1922 is located directly above the dilution funnel 19, and the second solenoid valve opens to flush away the slurry particles adhered to the inner wall of the dilution funnel 19 and the outer wall of the flushing nozzle 191.

[0028] Reference Figure 3 to Figure 5 The flushing ring 1922 includes a first half ring 19221 and a second half ring 19222 that are fixedly connected and communicated with each other (for example, by an integrated fixed connection), the first half ring 19221 and the second half ring 19222 are arranged in a circular ring shape and are communicated with each other; an extended flushing rod 19223 is fixedly connected to the middle of the first half ring 19221, and the first half ring 19221 and the extended flushing rod 19223 are fixedly connected and communicated in an ∈ shape (for example, fixed by welding). When the flushing ring 1922 is rotated to be located directly above the dilution funnel 19, the extended flushing rod 19223 is located directly above the flushing nozzle 191; the first water spray hole opened at the bottom of the extended flushing rod 19223 points to the flushing nozzle 191; there are a plurality of first water spray holes and they are arranged in an array along the length direction of the extended flushing rod 19223; the extended flushing rod 19223 is in the shape of a straight rod.

[0029] Reference Figure 5 A notch 1900 is provided on the opposite side of the upper side wall 190 , and the notch 1900 is used to provide an accommodating space for the robot module 6 that clamps the concentration pot 21 .

[0030] Reference Figure 5 and Figure 6The second water spray hole opened on the side wall of the first half ring 19221 is directed to the middle and lower part of the upper side wall 190 for flushing, and the third water spray hole opened on the side wall of the second half ring 19222 is directed to the side wall of the dilution funnel 19 below the notch 1900, thereby having a better flushing effect and avoiding the formation of a flushing blind area. A plurality of second water spray holes are provided and arranged along the axial direction of the first half ring 19221; a plurality of third water spray holes are provided and arranged along the axial direction of the second half ring 19222.

[0031] Reference Figure 1 and Figure 2 , the overflow pipe 14 is in an N shape; one end of the overflow pipe 14 is inserted in the middle of the top plate of the cyclone tube 11, and the other end is inserted in the receiving tube 151 at the top of the connecting tube 15; the top plate and the overflow pipe 14 are sealed and fixedly connected by welding; a ventilation gap for reducing siphoning is provided between the inner wall of the receiving tube 151 and the outer wall of the overflow pipe 14, thereby preventing the slurry particles with relatively large diameters from flowing into the filter container 16 too early and in large quantities through the connecting tube 15 due to the siphoning phenomenon. If the slurry particles with relatively large diameters flow into the filter container 16 too early and in large quantities, the filter holes at the bottom of the filter container 16 will be blocked, and both coarse and fine particles will accumulate in the filter container 16, reducing the water permeability of the filter container 16 and causing the slurry in the filter container 16 to overflow; if the slurry particles with relatively large diameters overflow and lose, the accuracy of the subsequent detection results will be reduced.

[0032] Reference Figure 2 A vertical support rod 140 is installed on the lower surface of the middle part of the overflow pipe 14, and the top end of the vertical support rod 140 is fixedly connected to the overflow pipe 14 (for example, fixedly connected by bolts or fixedly connected by welding); the bottom end of the vertical support rod 140 is fixedly connected to the top plate of the cyclone tube 11 (for example, fixedly connected by bolts or fixedly connected by welding), thereby realizing the reinforced fixation of the overflow pipe 14, avoiding the overflow pipe 14 from hitting the receiving tube 151, and at the same time avoiding the connection position between the overflow pipe 14 and the top plate of the cyclone tube 11 from shaking and loosening due to the impact of water flow, thereby improving the service life of the present invention.

[0033] Reference Figure 1 and Figure 2 The middle part of the connecting pipe 15 is spiral-shaped; the bottom of the connecting pipe 15 is provided with an inclined guide tube 152, which points to the discharge pipe 13; the guide tube 152 is L-shaped; the ends of the discharge pipe 13 and the guide tube 152 are both vertically arranged and point to the filter container 16, and the filter container 16 is placed on a water collecting base 17 that can be raised and lowered, and the bottom surface of the filter container 16 is provided with filter holes. The middle part of the connecting pipe 15 is spiral-shaped, which is used to reduce the flow rate of the slurry in the connecting pipe 15, and further reduce the flow rate of the slurry flowing out through the discharge pipe 13, thereby avoiding the problem of slurry splashing in the filter container 16, thereby improving the accuracy of subsequent detection results.

[0034] Reference Figure 1 and Figure 2 After the first valve body 131 is closed, conventional cyclone separation operation is performed, and the slurry particles with relatively large diameters accumulate at the bottom of the cyclone cylinder 11, and the slurry particles with relatively small diameters flow into the filter container 16 through the overflow pipe 14 and the connecting pipe 15 to achieve rough separation.

[0035] In the following, the slurry particles with a diameter smaller than the filter hole diameter are referred to as fine particles, and the slurry particles with a diameter larger than the filter hole diameter are referred to as coarse particles; the slurry particle flow with a relatively small diameter is referred to as the first flow, and the slurry particle flow with a relatively large diameter is referred to as the second flow.

[0036] After rough sorting, fine particles are more concentrated in the first material flow, and coarse particles are more concentrated in the second material flow; the fine particles in the first material flow can pass through the filter holes without the need for external stirring force. In the traditional technology, coarse and fine particles are mixed together, and a rotatable stirring claw for providing stirring force needs to be placed in the filter container 16. The filter container 16 is connected to an oscillator. When the filter container 16 oscillates up and down, the stirring fins of the stirring claw collide with the bottom plate or bottom filter of the filter container 16, causing grinding of the slurry particles. Some coarse particles are ground into fine particles, which pass through the filter container 16 and are lost, resulting in a decrease in the accuracy of subsequent detection results. The present invention avoids the use of stirring claws, thereby avoiding the occurrence of grinding and further improving the detection accuracy.

[0037] Reference Figure 1 and Figure 2 , the first valve body 131 can be opened and closed intermittently, so that the direct flushing liquid in the discharge pipe 13 and the overflow flushing liquid in the guide tube 152 can flow out alternately or simultaneously, thereby rinsing the inner cavity of the filter container 16. The flushing liquid is pure water injected into the cyclone tube 11 through the flushing ring 1922 after rough selection; the flushing liquid includes direct flushing liquid and overflow flushing liquid; the direct flushing liquid is the pure water in the cyclone tube 11 flowing out through the discharge pipe 13; the overflow flushing liquid is the pure water in the cyclone tube 11 flowing out through the connecting pipe 15; after the flushing ring 1922 stops injecting water, the first valve body 131 is closed, and the last tube of overflow flushing liquid flows out of the guide tube 152, and then the rinsing is completed. The rinsing operation is a single valve control form controlled by the first valve body 131, and there is no need to introduce additional control structures to avoid increased costs, increased operational complexity, and reduced reliability.

[0038] After roughing and sorting, close the second solenoid valve and the first liquid pump, open the first valve body 131, and allow the second material flow to slowly flow through the filter container 16. At this time, the pulp particles in the second material flow and the coarse particles in the first material flow that are screened after roughing are accumulated in the filter container 16 to form mixed particles (during the roughing process, the first material flow flowing out of the guide tube 152 has an impact force on the filter container 16, so that the coarse particles that are screened in the first material flow are impacted to the bottom of the discharge pipe 13, thereby achieving particle mixing). Then close the first valve body 131, open the second solenoid valve and the first liquid pump, and when the cyclone tube 11 is filled with pure water, intermittently open and close the first valve body 131 for rinsing.

[0039] When the discharge pipe 13 and the guide tube 152 flow out the flushing liquid alternately, the slurry particles move left and right in the inner cavity of the filter container 16 and roll; when the discharge pipe 13 and the guide tube 152 flow out the flushing liquid at the same time, the slurry particles in the filter container 16 are dispersed (the flushing liquid flow rate increases suddenly, the impact force increases suddenly, and the liquid level in the filter container 16 rises at the same time, so the fluidity of the mixed particles is improved, and the dispersion is achieved); thereby rinsing the mixed particles. The present invention uses the impact force of the water flow to replace the stirring force of the stirring claws, which is used for washing the mixed particles, avoiding the occurrence of grinding, and has higher detection accuracy.

[0040] Reference Figure 1 and Figure 2 , the middle part of the connecting pipe 15 is spiral, which is used to reduce the flow rate of pure water in the connecting pipe 15. During rinsing: if the first valve body 131 is closed, pure water will flow out of the bottom of the connecting pipe 15 after a specific time (the specific time is a fixed value, and the precise value can be obtained by calculation or the approximate value can be obtained through a limited number of experiments); if the first valve body 131 is opened, pure water will flow out of the discharge pipe 13 immediately; therefore, controlling the time interval of opening the first valve body 131 and the duration of each opening can control the discharge pipe 13 and the guide tube 152 to flow out the flushing liquid alternately or simultaneously, thereby meeting the rinsing requirements.

[0041] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 The cyclone tube 11 and the connecting tube 15 are both vertically arranged; the feed tube 12 and the receiving tube 151 are fixedly connected in a cross shape (for example, fixedly connected by a clamp or fixedly connected by welding); the outer side wall of the filter container 16 is provided with a horizontal grasping handle 161 (for example, fixedly connected by integral molding); the grasping handle 161 is used for grasping by the clamping claw in the manipulator module 6.

[0042] Reference Figure 8 and Fig. 9The cross section of the bottom of the discharge pipe 13 is rectangular, and the cross section of the bottom of the guide tube 152 is rectangular; the cross section of the filter container 16 is rectangular and fits with the bottom of the discharge pipe 13 and the guide tube 152; avoid too large a gap between the filter container 16, the discharge pipe 13 and the guide tube 152, and further avoid slurry splashing. The gaps between the filter container 16, the discharge pipe 13 and the guide tube 152 are all set within 5 mm.

[0043] Reference Figure 8 The outer surface of the side wall of the cyclone tube 11 is provided with a plurality of hoops, which are fixedly connected to the cross bracing ribs 18 (for example, by bolts or by an integrated fixed connection), and the spiral portion of the connecting pipe 15 is crimped and fixed to the upper surface of the cross bracing ribs 18 (for example, by welding).

[0058] The slurry fineness detection method uses slurry fineness detection equipment to detect the slurry fineness, and the steps include: S1. Place the concentration pot 21 on the lifting receiving plate 23, use a sampling tube to extract the slurry sample on site and inject it into the sampling funnel 22.

[0059] S2, the lifting base 24 pushes the concentration pot 21 upward, so that the concentration pot 21 is close to the sampling funnel 22; the second valve body 221 is opened for a limited time, and the sampling funnel 22 injects the slurry sample into the concentration pot 21; after the overflow is quantitative, the slurry sample in the concentration pot 21 is the slurry concentrate.

[0060] S3, the manipulator module 6 grabs the concentration pot 21 and places the concentration pot 21 on the first weighing module 3, and records the total weight of the concentration pot 21 and the slurry as m1; S4, the manipulator module 6 grabs the concentration pot 21, pours the slurry stock solution in the concentration pot 21 into the dilution funnel 19 and then turns it upside down on the flushing nozzle 191, and the flushing nozzle 191 flushes out the slurry particles adhering to the inner wall of the concentration pot 21 to obtain the slurry dilution liquid; the first liquid pump presses the slurry dilution liquid into the cyclone tube 11, and the slurry particles with relatively large diameters accumulate at the bottom of the cyclone tube 11, and the slurry particles with relatively small diameters flow into the filter container 16 through the overflow pipe 14 and the connecting pipe 15. The slurry dilution liquid has higher fluidity than the slurry stock solution and has a larger volume, so it can be gradually and slowly injected into the cyclone tube 11 for sorting; then by controlling the dilution ratio, the working efficiency of the cyclone tube 11 can be adapted, avoiding the problem that the power of the hydraulic cyclone separator 1 cannot adapt to the concentration of the slurry stock solution and resulting in poor sorting effect, and further avoiding the problem that the filter hole is blocked and the slurry overflows from the filter container 16, thereby improving the detection accuracy.

[0061] S5, opening the first valve body 131, and the slurry particles with relatively large diameters flow into the filter container 16; the first valve body 131 is intermittently opened and closed to flush the filter container 16, and the screened material is obtained.

[0062] S6, the water collecting base 17 drives the filter container 16 to move downward, the manipulator module 6 grabs the filter container 16, and turns the filter container 16 upside down in the recovery funnel 41; then the first lifting component 42 drives the recovery funnel 41 and the filter container 16 to move upward until the filter container 16 is placed in the inner cavity of the splash shield 43; the spray ring 432 is started, and the screened material is flushed into the recovery funnel 41; the spray ring 432 is closed, and the first lifting component 42 drives the recovery funnel 41 and the filter container 16 to move downward; the screened material in the recovery funnel 41 is allowed to settle.

[0063] S7, the robot module 6 grasps the concentration pot 21 and places the concentration pot 21 directly below the recovery funnel 41; opens the third valve body 411, and the sieve-surface fluid flows into the concentration pot 21; and then closes the third valve body 411.

[0064] S8, the manipulator module 6 places the concentration pot 21 on the second weighing module 5 and leaves it to stand, obtaining a large-particle ore slurry having the same volume as the original ore slurry. The total weight of the concentration pot 21 and the large-particle ore slurry is recorded as m3.

[0065] During steps S6 to S8, when the manipulator module 6 clamps the concentration pot 21, the anti-skid pad on the clamping claw is used to block the overflow hole 211 (when the overflow hole 211 is exposed, the slurry will flow out; the manipulator module 6 will inevitably vibrate during operation, which will cause excessive slurry to flow out, reduce the weight and volume of the slurry, and reduce the detection accuracy). At this time, the liquid level of the slurry is higher than the height of the overflow hole 211; then the concentration pot 21 is placed on the second weighing module 5, and the excess slurry overflows to achieve equal volume sampling. An air gun is installed on the manipulator module 6 or the support module 7 to blow off the water droplets adhering to the outer wall of the concentration pot 21 when the slurry overflows, thereby ensuring the weight accuracy.

[0066] During steps S6 to S8, by setting the position of the overflow port of the recovery funnel 41, the total volume of the material discharged from the recovery funnel 41 in a single time can be made slightly smaller than the volume of the concentration pot 21; then the spray ring 432 is started again to flush the inner wall of the recovery funnel 41 to ensure that the slurry particles are thoroughly collected. After standing for a period of time, the slurry particles obtained from the second flushing and part of the water are injected into the concentration pot 21 through the recovery funnel 41.

[0069] S92. Retrieve and query Table 1 to obtain the concentration c1 of the slurry solution corresponding to the weight m2 of the slurry solution: compare the value of m2 with the slurry weight data in the concentration measurement table one by one, and take the slurry percentage mass concentration value corresponding to the closest (for example, the absolute value of the difference is the smallest) slurry weight value * 100% as the c1 data.

[0070] S93. Calculate the density of the slurry solution ρ1, ρ1= (m2) / v.

[0071] S94. Calculate the weight of the large particle ore slurry m4, m4=m3-m.

[0075] S98, calculate the fineness of the slurry, .

[0076] S99. The fineness of the slurry stock is equal to the fineness of the slurry sample.

[0077] In this embodiment, the mass m of the concentration pot 21 is 196 grams; the volume of the concentration pot 21 is 513 milliliters; and the specific gravity ρ3 of the ore is 3.88 grams per cubic centimeter.

[0078] The following provides the derivation process of the calculation formula for the concentration c2 of the large particle ore slurry in step S96: Known: ore specific gravity ρ3, water density ρwater (take 1 gram per milliliter), mass m of concentration pot 21, volume v of concentration pot 21 = total volume vtotal of large particle ore slurry; the above calculation yields the density ρ2 of large particle ore slurry, Formula ①: The total mass of large particle ore slurry mtotal = ρ2*vtotal; Formula ②: mtotal = m5 + mwater, where m5 is the mass of the material on the screen, and mwater is the mass of water in the large particle ore slurry; Formula ③: m5=ρ3*vstone=ρ3*(vtotal-vwater), where vstone is the volume of the material on the sieve; Formula ④: mwater=vwater*ρwater=vwater; From formulas ① to ④, we can get: ρ2*vtotal=mtotal=m5+mwater=ρ3*(vtotal-vwater)+vwater=ρ3*vtotal-ρ3*vwater+vwater; Therefore, ρ2*vtotal-ρ3*vtotal=vwater-ρ3*vwater; Therefore, we get formula ⑤: ; From formulas ④ to ⑤, we can get: .

[0079] In the present invention, controlling the time interval of opening the first valve body 131 and the duration of each opening can control the discharge pipe 13 and the guide tube 152 to flow out the flushing liquid alternately or simultaneously, as described in detail below: After closing the first valve body 131, the flushing liquid flows through "the starting end of the overflow pipe 14, the end of the overflow pipe 14, the starting end of the receiving tube 151, the end of the receiving tube 151, the spiral part in the middle of the connecting tube 15, the starting end of the guide tube 152, and the end of the guide tube 152" in sequence. Assume that closing the first valve body 131 can generate an overflow flow composed of flushing liquid, and the time required for the flow front of the overflow flow to flow from the starting end of the overflow pipe 14 to the end of the overflow pipe 14 is 1 second, and the time required for the flow front of the overflow flow to flow from the end of the overflow pipe 14 to the end of the guide tube 152 is 4 seconds; similarly, the time required for the flow tail of the overflow flow to flow from the starting end of the overflow pipe 14 to the end of the overflow pipe 14 is 1 second, and the time required for the flow tail of the overflow flow to flow from the end of the overflow pipe 14 to the end of the guide tube 152 is 4 seconds.

[0080] Reference Fig. 20 Assuming that the time interval for opening the first valve body 131 is 5 seconds and the duration of each opening is 5 seconds, taking the starting time of closing the first valve body 131 as the reference time point, the overflow flow appears at the end of the overflow pipe 14 after a delay of 1 second and the overflow flow lasts for 5 seconds, the overflow flow appears at the end of the overflow pipe 14 after a delay of 5 seconds and the overflow flow lasts for 5 seconds, and after the first valve body 131 is opened, the flushing liquid flow appears immediately at the end of the discharge pipe 13 and the flushing liquid flow lasts for 5 seconds. Therefore, the technical purpose of the discharge pipe 13 and the guide tube 152 simultaneously discharging the flushing liquid is achieved within the actual time period of 5 to 10 seconds, 15 to 20 seconds.....

[0081] Reference Fig.21 Assuming that the time interval for opening the first valve body 131 is 2.5 seconds and the duration of each opening is 2.5 seconds, taking the starting time of closing the first valve body 131 as the reference time point, the overflow flow appears at the end of the overflow pipe 14 after a delay of 1 second and the overflow flow lasts for 2.5 seconds, the overflow flow appears at the end of the overflow pipe 14 after a delay of 5 seconds and the overflow flow lasts for 2.5 seconds, and after the first valve body 131 is opened, the flushing liquid flow appears immediately at the end of the discharge pipe 13 and the flushing liquid flow lasts for 2.5 seconds. Therefore, the technical purpose of alternately discharging flushing liquid from the discharge pipe 13 and the guide tube 152 is achieved within the actual time period of 2.5 to 7.5 seconds, 7.5 to 12.5 seconds.....

[0082] The time required for the front / tail of the overflow flow to flow from the end of the overflow pipe 14 to the end of the guide tube 152 is related to the pipe diameter, the number of spiral turns, and the spiral diameter of the middle part of the connecting pipe 15. Therefore, using connecting pipes 15 of different specifications can control the length of this time, thereby adapting the opening interval of the first valve body 131 and the duration of each opening, and further adapting to the detection requirements of slurry samples of different specifications (slurries of different specifications have different sedimentation rates, and different rinsing impact frequencies are required to adapt to the sedimentation rate).

[0083] Each opening and closing of the first valve body 131 will cause wear of the internal structure, so the service life of the first valve body 131 is usually expressed in the form of the total number of opening and closing times; under the premise of adapting to the slurry settling speed, the rinsing impact frequency is reduced as much as possible, thereby reducing the opening and closing frequency requirements of the first valve body 131, which can enable the first valve body 131 to be used for a longer time.

[0084] The connecting pipe 15 includes a receiving tube 151 and a flow guide tube 152 at two ends, so the end of the connecting pipe 15 is the end of the flow guide tube 152 .

[0085] When the first valve body 131 is opened, the flow rate of the flushing liquid at the position of the discharge pipe 13 is equal to the flow rate of the flushing liquid at the position of the feed pipe 12 (achieved by selecting a discharge pipe 13 with a suitable diameter and adapting the opening degree of the first valve body 131) to ensure that overflow does not occur at this time and the liquid level of the flushing liquid in the cyclone 11 remains basically stable without a significant drop.

[0086] In the present invention, the first valve body 131, the second valve body 221, and the third valve body 411 are all electrically controlled pneumatic switch angle valves; the first linear drive, the second linear drive, and the third linear drive are all electric push rods, pneumatic push rods, hydraulic push rods, or a combination thereof (e.g., electro-hydraulic push rods). The first valve body 131, the second valve body 221, the third valve body 411, the first solenoid valve, the second solenoid valve, the third solenoid valve, the fourth solenoid valve, the fifth solenoid valve, the first linear drive, the second linear drive, the third linear drive, and other electrically controlled components are connected to an external power supply and a computer through an electrical cabinet, and the computer controls the start and stop of each electrically controlled component of the present invention through the electrical cabinet.
