Description

Technical Field

[0001] The present invention relates to the technical field of mining machinery, and particularly relates to a water-coal separation system and a separation component. Background Art

[0002] At present, the coal-water separation methods at home and abroad are roughly divided into: gravity dehydration, centrifugal dehydration, filtration dehydration, pressure filtration dehydration, filter aid-assisted dehydration technology, etc. Recently, with the continuous improvement of equipment, the performance has been greatly improved, and the promotion and application are relatively fast. The filter aid-assisted dehydration technology is considered to be a promising dehydration technology. It can change the particle structure of the suspension, form a loose and porous aggregate, play a role in changing the specific resistance of the filter cake, improve the filtration efficiency, and reduce the moisture content of the filter cake.

[0003] The Chinese patent with the application number CN202111319699.4 discloses a coal-water separation device, which includes a base, a filter cylinder, a feed bin, a hydraulic cylinder and a filter screen. The base is fixedly connected to the machine table, the filter cylinder is rotatably connected to the base, the feed bin abuts against the top of the filter cylinder to introduce a coal-water mixture into the filter cylinder, the hydraulic cylinder is fixedly connected to the base, and the filter screen abuts against the bottom of the inner cavity of the filter cylinder; wherein a telescopic rod is slidably connected in the hydraulic cylinder, one end of the telescopic rod extends into the filter cylinder, and a pushing plate is fixedly connected to the end of the telescopic rod extending into the filter cylinder, and the pushing plate abuts against the filter screen; a slag discharge port is provided between the filter cylinder and the hydraulic cylinder, and the telescopic rod retracts to enable the pushing plate to push the coal slag towards the slag discharge port.

[0004] It is found in the above-mentioned prior art that during the process of the coal-water separation process, there are numerous small coal slag particles inside the coal blocks. Once these small particle coal blocks are mixed with water, a coal slime mixture will be formed. However, in view of the existing technical means, the simple centrifugal method has poor effect in separating the water in the coal slime mixture. At the same time, during the process of separating the water in the coal slime mixture, due to the sudden drop in the water content of the coal slime mixture after separation, a large amount of residual coal slime will adhere to the inside of the separation component, such as adsorbing on the inner wall and blocking in small gaps, etc., and it is difficult to be discharged. This not only affects the separation effect, but also may cause equipment operation failures, increasing the uncertainty and maintenance cost in the production process.

[0005] Therefore, it is necessary to solve the above problems through a water-coal separation system and a separation component. Summary of the Invention

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1: As Figures 1 to 10 shown, this embodiment discloses a separation component, including a separation structure 3 and a drum sieve 303. Inside the drum sieve 303, there are respectively a first annular support frame 306, a second annular support frame 309 and a third annular support frame 310. One side of the first annular support frame 306 is provided with a first baffle 317, and one side of the third annular support frame 310 is provided with a second baffle 318. The inner walls of the first annular support frame 306, the second annular support frame 309 and the third annular support frame 310 are all provided with the same filter screen 311. The inner surface of the filter screen 311 is provided with a spiral blade 314 for conveying materials. The drum sieve 303 is provided with a rotating shaft 308 through the second baffle 318. The left and right ends of the rotating shaft 308 are provided with two symmetrically arranged sliding sleeves 315. The first annular support frame 306 and the third annular support frame 310 are both connected to the outer surfaces of the two sliding sleeves 315 through connecting rods 307. A limiting sleeve 316 is arranged between the two sliding sleeves 315, and the inside of the limiting sleeve 316 is connected to the outer surface of the rotating shaft 308. One end of the rotating shaft 308 away from the drum sieve 303 is provided with a driving power source 301 through an output shaft 302. The driving power source 301 is used to control the rotation of the rotating shaft 308, and a positioning plate is arranged at the bottom of the driving power source 301.

[0036] One side surface of the second baffle 318 is provided with a discharge port. Inside the discharge port, a first electromagnetic valve is provided. Inside the discharge port, a conveying pipe 304 is communicatively connected. One end of the conveying pipe 304 away from the second baffle 318 is communicatively connected to an air pump 305. The drum screen 303 discharges the separated slime mixture outward through the air pump 305 and the conveying pipe 304. The outer side surface of the second baffle 318 is slidably arranged inside the drum screen 303. The discharge port on the second baffle 318 is magnetically connected to one end of the conveying pipe 304. When the second baffle 318 is in a rotating state, the discharge port on the second baffle 318 is no longer communicatively connected to the end of the conveying pipe 304.

[0037] During use, a discharge port, a first electromagnetic valve and an air pump 305 are arranged on the second baffle 318. After the slime mixture is separated inside the drum screen 303, the first electromagnetic valve is opened. The airflow generated by the air pump 305 can form a certain pressure difference to push the separated slime mixture to be discharged through the discharge port and the conveying pipe 304. This design solves the problem that it is difficult to efficiently discharge the separated slime mixture. With the assistance of the air pump 305 for conveying, the discharge efficiency is greatly improved, achieving the effect of quickly and stably discharging the separated slime mixture. At the same time, the second baffle 318 and the conveying pipe 304 are magnetically connected. When the second baffle 318 is in a stationary state, the discharge port and the conveying pipe 304 are tightly communicatively connected under the action of magnetic force to ensure the smooth conveying of the slime mixture. When the second baffle 318 rotates driven by the rotating shaft 308, the communicative connection state between the discharge port and the conveying pipe 304 is cut off, effectively preventing the leakage of materials when they do not need to be discharged, well solving the problem of controlling the opening and closing of the discharge port, and achieving the effect of flexibly controlling the discharge, and the discharge timing can be accurately controlled according to the actual production requirements.

[0038] The outer side surface of the first baffle 317 is provided with a feed port 319. Inside the feed port 319, a second electromagnetic valve is provided. The interiors of both the first baffle 317 and the second baffle 318 are slidably connected to the outer side surface of the rotating shaft 308. The left and right ends of the limiting sleeve 316 are respectively provided with a first electric drive rod 312 and a second electric drive rod 313. The output ends of the first electric drive rod 312 and the second electric drive rod 313 are respectively connected to two symmetrically arranged sliding sleeves 315. The first electric drive rod 312 and the second electric drive rod 313 are used to respectively control the two sliding sleeves 315 to slide horizontally along the surface of the rotating shaft 308. The inner diameter surfaces of the first annular support frame 306, the second annular support frame 309 and the third annular support frame 310 are all provided with microwave moisture sensors. The first annular support frame 306, the second annular support frame 309 and the third annular support frame 310 all detect the moisture content data of the slime mixture through the microwave moisture sensors.

[0039] During use, a feed inlet 319 and a second electromagnetic valve are provided on the first baffle 317. When the material needs to enter the drum sieve 303, the second electromagnetic valve is opened, and the material can smoothly enter from the feed inlet 319. When feeding is not required, the second electromagnetic valve is closed to prevent the material from entering randomly, solving the control problem of the material entering the drum sieve 303, achieving effective control of the feeding amount and feeding time, and avoiding material waste and adverse effects on the separation effect caused by too much or too little feeding.

[0040] In addition, the first baffle 317 is slidably connected to the second baffle 318 and the rotating shaft 308. When the rotating shaft 308 rotates driven by the drive power source 301, the baffle will not hinder the normal operation of the rotating shaft 308, solving the adaptation problem between the baffle and the rotating component, ensuring the stable operation of the entire separation structure 3, and achieving the effect that the baffle does not affect the rotation of the rotating shaft 308.

[0041] At the same time, a first electric drive rod 312 and a second electric drive rod 313 are provided to control the lateral sliding of the sliding sleeve 315. When the position of the sliding sleeve 315 needs to be adjusted, the first electric drive rod 312 or the second electric drive rod 313 is started, and its output end pushes the sliding sleeve 315 to move laterally along the surface of the rotating shaft 308. For example, when processing materials of different particle sizes, by adjusting the position of the sliding sleeve 315, the force distribution of the internal support structure of the drum sieve 303 can be changed, so that the filter screen 311 and the spiral blade 314 can better play the role of pressure filtration and centrifugal separation, achieving the effect of being able to flexibly adjust the position of the sliding sleeve 315 according to needs, further optimizing the structural stability and functionality, and improving the adaptability of the separation structure 3 to different working conditions.

[0042] Embodiment 2: This embodiment discloses a water-coal separation system, including a separation host body 1 and the separation component of Embodiment 1. The separation component is arranged inside the separation host body 1. A support component 2 is provided at the bottom of the separation host body 1 for supporting the separation host body 1. The separation host body 1 includes a host shell 101. A support plate 102 is provided on one side of the inner wall of the host shell 101. A compression spring 104 is provided above the support plate 102. A drainage plate 103 is provided on the support plate 102 through the compression spring 104. One side of the drainage plate 103 is hingedly provided with a support rod 106. The drainage plate 103 is hingedly provided with a sieve plate 105 through the support rod 106. The separation host body 1 further includes a diversion chamber 107. The surface of the diversion chamber 107 is in contact with one side of the drainage plate 103. A feed channel 108 is provided at the bottom of the diversion chamber 107. A feed valve 109 is provided at one end of the feed channel 108 close to the diversion chamber 107. The feed valve 109 is used to control the material to enter the inside of the feed channel 108.

[0043] During use, a support plate 102, a compression spring 104, a drainage plate 103, a support rod 106, and a sieve plate 105 are arranged inside the separation host body 1. After the material enters the separation host body 1, it first falls on the drainage plate 103. Under the action of gravity, the material flows downward along the drainage plate 103. The compression spring 104 has elasticity. When the gravity of the material and the impact force generated by the flow act on the drainage plate 103, the compression spring 104 will undergo elastic deformation, causing the drainage plate 103 to generate a certain amount of shaking. This shaking helps to disperse and preliminarily screen the material. At the same time, the support rod 106 is hinged to the drainage plate 103 and the sieve plate 105. During the shaking process of the drainage plate 103, the angle of the support rod 106 will also change, further assisting in screening the coal blocks on the sieve plate 105, solving the problems of drainage and preliminary screening of the material in the separation host body 1, and achieving the effect of effectively draining and preliminarily screening the material.

[0044] In addition, a diversion bin 107, a feed channel 108, and a feed valve 109 are provided. When it is necessary to convey the material into the separation host body 1, the feed valve 109 is opened, and the material enters through the feed channel 108 from the diversion bin 107. The feed valve 109 can accurately control the timing and flow rate of the material entering. According to the working state of the separation host body 1 and the material processing requirements, the material entry is reasonably arranged, avoiding the situation of material accumulation or insufficient supply, solving the control problem of the material entering the separation host body 1, and achieving the effect of accurately controlling the timing and flow rate of the material entering.

[0045] A limiting block is provided at the bottom of the drainage plate 103. A transmission rod is provided inside the limiting block. One end of the transmission rod away from the limiting block is provided with a vibrator. The vibrator is used to control the drainage plate 103 to generate vibration through the transmission rod. When the vibrator controls the drainage plate 103 to be in a vibrating state, the compression spring 104 is frequently in a state of contraction and stretching, the distance between the drainage plate 103 and the sieve plate 105 is frequently in a state of shrinking and expanding, and the support rod 106 is also frequently in a state of angular deflection.

[0046] The support assembly 2 includes a support platform 201. The upper part of the support platform 201 is arranged at the bottom of the host housing 101. The support platform 201 is used to support the host housing 101. Four symmetrically arranged load-bearing rods 202 are provided at the bottom of the support platform 201. The bottom ends of the load-bearing rods 202 are in contact with the ground. A funnel 111 is connected and provided at the bottom of the host housing 101. A drain pipe 110 is provided at the bottom of the funnel 111. The drain pipe 110 penetrates through the support platform 201. The drain pipe 110 is arranged on the outer surface of the support platform 201. The separated water in the host housing 101 is discharged to the outside through the funnel 111 and the drain pipe 110.

[0047] During use, a limit block, a transmission rod, and a vibrator are provided at the bottom of the drainage plate 103. After the vibrator is started, high-frequency vibration is generated. This vibration is transmitted to the drainage plate 103 through the transmission rod, causing the drainage plate 103 to vibrate strongly. The material on the vibrating drainage plate 103 can come into contact with the sieve plate 105 more fully, increasing the chance of the material being screened, solving the problem of the vibration drive of the drainage plate 103, realizing the vibration of the drainage plate 103 by the vibrator, and enhancing the effect of material screening. During the process of the vibrator vibrating the drainage plate 103, the compression spring 104 is frequently in a state of contraction and stretching. When the compression spring 104 contracts, the distance between the drainage plate 103 and the sieve plate 105 decreases, enhancing the extrusion and screening effect on the material. When the compression spring 104 stretches, the distance expands, and the material has more space for movement, facilitating the turning and further screening of the material. At the same time, the support rod 106 also frequently deflects at an angle along with the vibration of the drainage plate 103, assisting the movement and screening of the material on the sieve plate 105, solving the problem of the effective treatment of the material during vibration, realizing the effect of better screening and processing of the material, and improving the screening quality and efficiency of the material.

[0048] In addition, by setting the support assembly 2, including a support platform 201 and load-bearing rods 202, the support platform 201 is located at the bottom of the main machine housing 101, and the load-bearing rods 202 are evenly distributed at the bottom of the support platform 201 and contact the ground, forming a stable support structure. The main machine housing 101 and various components inside it are relatively heavy. The support assembly 2 can bear the gravity of the main machine housing 101 and evenly disperse it to the ground, solving the support problem of the separation main machine body 1, realizing the effect of stably supporting the separation main machine body 1, ensuring the stability of the separation main machine body 1 during operation, and avoiding equipment damage or affecting the separation effect caused by unstable support.

[0049] By communicating and setting a funnel 111 and a drain pipe 110 at the bottom of the main machine housing 101, when the water-coal separation of the material is completed in the separation main machine body 1, the separated water flows into the funnel 111 under the action of gravity and then is discharged to the outside through the drain pipe 110. The design of the funnel 111 can effectively collect the separated water. The drain pipe 110 passes through the support platform 201 and is arranged on its outer surface, facilitating the discharge of water, solving the problem of discharging the separated water, realizing the effect of smoothly discharging the separated water to the outside, ensuring the dry environment inside the separation main machine body 1, and being beneficial to the normal operation and service life extension of the equipment.

[0050] Although the centrifugal separation of the slime mixture is achieved through the mutual transmission and cooperation of the drive rod power source to control the rotating shaft 308, the first annular support frame 306, the second annular support frame 309, and the third annular support frame 310, due to the full contact between small particles such as slime and water, the water in the slime mixture cannot be completely separated only by the centrifugal separation method. As a result, the water content in the slime mixture after centrifugal separation is still higher than the preset value and cannot be separated for secondary utilization. At this time, it is necessary to perform pressure filtration on the slime mixture with a high water content during the centrifugal separation process to maximize the separation of the water in the slime mixture. Among them, the microwave moisture sensor is used to detect, record, and collect the moisture data of the slime mixture in the drum screen 303. At the same time, according to the data feedback detected by the microwave moisture sensor, the separation strategy is dynamically adjusted. Based on this, the specific adjustment steps are as follows:

[0051] Use the microwave moisture sensors on the first annular support frame 306, the second annular support frame 309, and the third annular support frame 310 to detect and record the moisture in the slime mixture.

[0052] After fine particles such as the slime mixture enter the interior of the feed channel 108 through the diversion bin 107 and the feed valve 109, the second solenoid valve in the feed port 319 on the first baffle 317 is opened to receive the slime mixture and fine particle water coal in the feed channel 108, so that the material will slowly enter the interior of the drum screen 303 through the feed port 319. At this time, the drive power source 301 controls the rotating shaft 308 to rotate. At the same time, under the action of the transmission rod of the connecting rod 307, the first annular support frame 306, the second annular support frame 309 and the third annular support frame 310 are simultaneously driven to rotate following the rotating shaft 308. In addition, the first annular support frame 306, the second annular support frame 309 and the third annular support frame 310 will drive the filter screen 311 and the spiral blade 314 to rotate simultaneously. At the same time, under the rotation action of the spiral blade 314, the slime mixture and fine particle water coal slowly entering the interior of the drum screen 303 will be slowly conveyed in the direction of the second baffle 318. After the material is completely conveyed, only need to close the second solenoid valve and at the same time close the feed valve 109 in the feed channel 108, so that the slime mixture cannot enter the diversion bin 107 and enter the interior of the drum screen 303 through the feed channel 108. At this time, with the working state of the drive power source 301, the slime mixture is slowly conveyed in the direction of the second baffle 318 by using the spiral blade 314, so that the slime mixture is evenly distributed in the interior of the drum screen 303. Subsequently, control the drive power source 301 to increase the rotation speed and cooperate with the filter screen 311 to generate centrifugal force on the slime mixture, so that the moisture in the slime mixture is separated through the filter screen 311, and the separated moisture is secondarily filtered by the drum screen 303 and discharged into the interior of the main machine housing 101. Subsequently, the discharged water will be discharged to the outside through the funnel 111 and the drain pipe 110, thus realizing the work of water coal separation.

[0053] After completing the centrifugal separation work, by reducing the rotation speed of the drive power source 301, the slime mixture is redistributed evenly in the interior of the drum screen 303. At this time, only need to use the microwave moisture sensors on the first annular support frame 306 and the second annular support frame 309 to detect the moisture content data in the slime mixture and obtain the moisture data. Subsequently, compare the moisture data with the moisture data (preset value) that meets the discharge requirement. The microwave moisture sensors on the first annular support frame 306 and the third annular support frame 310 respectively detect the moisture of the water coal mixture in the two end regions inside the drum screen 303, which are denoted as region A and region B for subsequent representation.

[0054] When the microwave moisture sensor detects that the moisture content value in the slime mixture is within the preset value, it indicates that the slime mixture has reached the discharge standard in terms of water content through centrifugal separation. At this time, only need to normally start the drive power supply 301 and cooperate with the spiral blade 314 to pump out the dehydrated slime mixture to the outside through the air pump 305 and the delivery pipe 304 without any treatment.

[0055] It should be noted that although the spiral blade 314 will play a guiding role for the slime mixture during rotation, after the drive power supply 301 increases the rotation speed and generates a strong centrifugal force on the slime mixture, the slime mixture will not be guided by the spiral blade 314 and its position will no longer change.

[0056] When the microwave moisture sensor detects that the moisture content value in the slime mixture is higher than the preset value, it indicates that the moisture in the slime mixture has not been completely separated through centrifugal separation. At this time, start the drive power supply 301 to rotate and control the spiral blade 314 to rotate through the rotating shaft 308. During this process, if the drive power supply 301 rotates clockwise, it will cooperate with the spiral blade 314 to gradually move the slime mixture from area A to area B. At this time, during the guiding process of the spiral blade 314, the slime mixture in area A is transported to area B, so the slime mixture in area B will gradually increase while the slime mixture in area A will become less and less. At this time, control the first electric drive rod 312 to make the sliding sleeve 315 in area A move gradually along the rotating shaft 308 towards the direction of the limit sleeve 316, thereby driving the first annular support frame 306 to move towards the middle along the inner wall of the drum screen 303. At this time, the accommodation space in area A shrinks, and the slime mixture in area A is also gradually transported to area B. When the sliding sleeve 315 moves to the specified position, it stops moving. At this time, the state of the first annular support frame 306 is as Figure 9As shown in the figure, the drive power supply 301 is then controlled to drive the rotating shaft 308 to rotate in the reverse direction, and cooperate with the spiral blade 314 to gradually convey the slime mixture in area B to area A. Since the space in area A has been reduced, the slime mixture will quickly fill and saturate area A during the reverse rotation and conveyance of the slime. At the same time, during the conveyance to area A, the second electric drive rod 313 is controlled to move the sliding sleeve 315 in area B towards the direction of the limit sleeve 316, so that the accommodation space in area B gradually decreases. After the adjustment is completed, the accommodation spaces in area A and area B are kept consistent. At this time, all the slime mixture in the drum screen 303 gathers in the middle area of the drum screen 303 in the area of the limit sleeve 316. Subsequently, the first annular support frame 306 and the third annular support are simultaneously controlled to slide horizontally towards the direction of the second annular support frame 309 through the mutual cooperation of the first electric drive rod 312 and the second electric drive rod 313, and cooperate with the stacking of the spiral blade 314 to achieve the pressure filtration effect on the slime mixture. The water separated by pressure filtration will automatically escape from the filter holes on the filter screen 311 into the drum screen 303. After secondary filtration, it is discharged to the outside through the funnel 111 and the drain pipe 110, so as to achieve the purpose of separating the slime mixture with a high water content by a combination of centrifugation and pressure filtration.

[0057] In addition, after the pressure filtration separation is completed, the first electric drive rod 312 and the second electric drive rod 313 are simultaneously controlled to drive the first annular support frame 306 and the third annular support frame 310 to move along the rotating shaft 308 towards both ends of the drum screen 303 and return to the initial position through the sliding sleeve 315. Subsequently, the drive motor is controlled to rotate counterclockwise first and cooperate with the spiral blade 314 to convey the slime mixture towards the direction of the first baffle 317. Then, the rotation direction of the drive power supply 301 is quickly set to clockwise rotation, and the slime mixture is conveyed from area A to area B, so that the gathered slime mixture is evenly distributed again inside the drum screen 303. Subsequently, the moisture content of the slime mixture in areas A and B is detected again by the microwave moisture sensor.

[0058] When the microwave moisture sensor in area A detects that the moisture content of the slime mixture is still higher than the preset value, the first electric drive rod 312 is used to control the sliding sleeve 315 in area A to move along the rotating rod towards the direction of the limit sleeve 316. During the movement, the first annular support frame 306 will also move towards the direction of the limit sleeve 316 together with the sliding sleeve 315. During this process, the spiral blade 314 on the filter screen 311 will slowly stack and extrude the slime mixture in area A. When the first annular support frame 306 is controlled to move to the specified area, the movement stops. For the specific state, please refer to Figure 9, so that the distance between two adjacent spiral vanes 314 is shortened and the internal coal slime mixture is squeezed and limited to prevent the position of the coal slime mixture from changing. Subsequently, the driving power supply 301 is controlled to generate a centrifugal force on the coal slime mixture in area A by means of the rotating shaft 308. At the same time, during the rotation of the driving power supply 301, the first electric drive rod 312 is gradually controlled to make the sliding sleeve 315 gradually move towards the direction of the limiting sleeve 316, and the distance between the spiral vanes 314 is gradually reduced. In cooperation with the filter screen 311, a local centrifugal combined pressure filtration method is used to perform secondary dehydration on the coal slime mixture. Subsequently, the moisture data in the coal slime mixture in area A is detected again by the microwave moisture sensor. At the same time, the first electric drive rod 312 is controlled to control the sliding sleeve 315 in area A to make the first annular support frame 306 quickly move horizontally back and forth along the rotating shaft 308, so that the filter screen 311 frequently contracts and expands to generate vibration, and this vibration is used to scatter the pressure-filtered coal slime mixture, reducing the density of the coal slime mixture, so that the moisture hidden between the small particles of the coal slime mixture flows out to the outside through the vibration until the moisture data detected by the microwave moisture sensor is within the preset value.

[0059] When the coal-water separation work is completed, after the coal-water separation, the viscosity of the coal slime mixture will increase due to the sudden decrease in moisture. Therefore, during the discharging process, the air pump 305 and the conveying pipe 304 cannot completely absorb and discharge the coal slime mixture in the drum screen 303 to the outside, resulting in a large amount of residual materials adhering to the gaps between the filter screen 311 and the spiral vanes 314, which is not easy to clean. If it remains in the roller screen for a long time, the coal slime mixture will accumulate more and more, causing serious wear and reducing the service life of the separation equipment. At this time, first control the first electric drive rod 312 and the second electric drive rod 313 to simultaneously control the first annular support frame 306 and the third annular support frame 310 to move horizontally back and forth along the rotating shaft 308 towards the direction of the limiting sleeve 316, so that the entire filter screen 311 is frequently in a state of contraction and expansion, thus generating high-frequency vibration. At this time, since the speed of each reciprocating movement of the first annular support frame 306 and the third annular support frame 310 is relatively fast, the adjacent two spiral vanes 314 will frequently stack and contact, so as to realize the shedding of the adsorbed coal slime mixture with the generated vibration. In addition, the coal slime mixture adhering to the filter screen 311 will also be shed by the generated vibration. The sides close to the second annular support frame 309 will all contact and collide with the second annular support frame 309. The coal slime mixture that has fallen off from the filter screen 311 and the spiral vanes 314 will be slowly conveyed to the vicinity of the discharge port on the second baffle 318 along with the rotation of the spiral vanes 314. Subsequently, the first electromagnetic valve is opened and the air pump 305 is used to suck the remaining coal slime mixture into the outside.

[0060] It should be noted that: at the same time, since the feeding channel 108 and the feeding port 319 on the first baffle 317 are magnetically connected, when the position of the first baffle 317 changes, the first baffle 317 no longer contacts and connects with the feeding channel 108. In addition, when the first baffle 317 rotates, the feeding port 319 will also be misaligned and not contact and connect with the feeding channel 108. In addition, before the feeding port 319 of the first baffle 317 is disconnected from the feeding channel 108, it is necessary to ensure that all the slime mixture and small-particle water-coal mixture materials in the feeding channel 108 completely enter the inside of the drum screen 303. In addition, the filtering screen 311 is made of a flexible material such as non-woven fabric or textile material, and the spiral blade 314 is made of elastic rubber material.
