Description

Technical Field

[0001] The invention relates to the field of separation technology, and in particular to a slag separation and recovery device and a separation and recovery process for mica pulping. Background Art

[0002] Separation equipment can be used to separate different substances. Separation equipment is applied in various fields. For example, separation equipment is needed to separate slag from mica pulping in the papermaking field. Slag separation is an important part of the production process. The main purpose is to separate the solid particles (slag) from the liquid in the mica slurry, ensure that the slag is effectively treated, and recover the reusable mica powder.

[0003] For example, Chinese patent CN221207155U discloses a sedimentation separation device for mica powder production. The solution is provided with a sedimentation tank, a feed pipe, a fixed ring, a filter cloth, a transmission component, a discharge pipe, a negative pressure valve, a support plate and a pumping component. When in use, the solid and liquid of the mica powder to be separated are put into the sedimentation tank from the feed pipe for sedimentation, and then the fixed ring and the filter cloth are connected and fixed to the transmission component by fixing bolts. After a certain period of sedimentation, the solid will be deposited at the bottom of the inner cavity of the sedimentation tank, and then the transmission component is started, the transmission component drives the fixed ring to move downward, and the fixed ring drives the filter cloth to move downward. Through the downward squeezing of the filter cloth, the liquid will be placed on the top of the filter cloth through the filter holes of the filter cloth, and the solid will be placed on the bottom of the filter cloth. The solid and liquid are separated by squeezing the filter cloth, and then the liquid on the top of the filter cloth is extracted from the inner cavity of the sedimentation tank by the pumping component. After the liquid is extracted, the negative pressure valve is opened to discharge the solid from the bottom of the inner cavity of the sedimentation tank through the discharge pipe, thereby realizing solid-liquid separation.

[0057] Refer to the following Figure 1-Figure 15 The present invention will now be used to describe a slag separation and recovery device for mica pulping.

[0058] A slag separation and recovery device for mica pulping, comprising a cylinder 110, a rotating cylinder 120 is arranged in the cylinder 110, the rotating cylinder 120 is coaxially arranged with the cylinder 110, a spiral plate 200 is arranged in the space between the rotating cylinder 120 and the cylinder 110, and the cavity between the spiral plate 200 and the rotating cylinder 120 is divided into a stirring area 130, an auxiliary drainage area 140 and a pressure holding area 150 in sequence along the circumferential direction. Figure 3 As shown, the cavity between the spiral plate 200 and the rotating cylinder 120 is respectively a stirring zone 130, an auxiliary drainage zone 140 and a pressure holding zone 150 in a clockwise direction, and the volumes of the stirring zone 130, the auxiliary drainage zone 140 and the pressure holding zone 150 gradually decrease. The stirring zone 130 is used to stir the slag-material mixture, the auxiliary drainage zone 140 is used to assist in the separation of the liquid in the slag, and the pressure holding zone 150 is used to further reduce the liquid in the slag when the slag is discharged.

[0059] The stirring zone 130 is provided with a feed port 111, which is specifically provided at the starting end of the stirring zone 130, and the pressure holding zone 150 is provided with a discharge port 112. The slag-material mixture enters the stirring zone 130 from the feed port 111. As the rotating drum 120 rotates, the slag-material mixture enters the auxiliary drainage zone 140, and then passes through the pressure holding zone 150 and is discharged from the discharge port 112, thereby completing the separation of solid matter and liquid matter in the slag.

[0060] A plurality of telescopic plates 210 are arranged on the outer peripheral wall of the rotating cylinder 120. The plurality of telescopic plates 210 are distributed along the radial direction of the rotating cylinder 120. The plurality of telescopic plates 210 can be telescoped along the radial direction of the rotating cylinder 120. One end of the telescopic plate 210 is always in sliding contact with the spiral plate 200. A compression chamber 220 is formed between two adjacent telescopic plates 210. When the rotating cylinder 120 rotates, the telescopic plates 210 are driven to rotate around the axis of the rotating cylinder 120. As the distance between the spiral plate 200 and the rotating cylinder 120 becomes closer and closer, the volume of the compression chamber 220 gradually decreases, and the compressed air entering the compression chamber 220 is compressed. The slag mixture is gradually squeezed, and a plurality of through holes 121 are provided on the side wall of the rotating cylinder 120. The liquid substance in the slag mixture is discharged from the compression chamber 220 through the through holes 121 on the rotating cylinder 120. An auxiliary drainage mechanism is provided in each compression chamber 220. The auxiliary drainage mechanism includes a stirring plate 233 and an auxiliary drainage assembly. The stirring plate 233 stirs the slag mixture in the stirring area 130 to make the slag mixture evenly mixed. At the same time, the stirring plate 233 can reduce the probability of solid matter in the slag blocking the through holes 121 during stirring, thereby improving the filtration efficiency of the compression chamber 220.

[0061] It should be noted that, in order to ensure the stability of the cylinder 110 , a support ring frame 100 is provided outside the cylinder 110 , and the discharge port 112 is connected to the upper surface of the support ring frame 100 .

[0062] The auxiliary drainage component is used to assist the compression chamber 220 in draining water, and the drainage volume of the auxiliary drainage component is negatively correlated with the content of solid matter in the slag mixture. That is to say, when the solid matter content in the slag mixture in the compression chamber 220 is relatively high, it means that the water content in the slag mixture is relatively low, and the drainage volume of the auxiliary drainage component is relatively low; when the solid matter in the slag mixture in the compression chamber 220 is relatively low, it means that the water content in the slag mixture is relatively high, and the drainage volume of the auxiliary drainage component will increase, so that the water content of the slag in the compression chamber 220 tends to a stable value after the slag mixture in the compression chamber 220 is filtered through the compression chamber 220, thereby avoiding the fluctuation of the water content of the slag after filtering due to different water contents of the slag mixture.

[0063] Specifically, the auxiliary drainage component includes a conical cylinder 230, which is located on the rotating cylinder 120 and distributed along the radial direction of the rotating cylinder 120. The conical cylinder 230 is specifically located between two adjacent telescopic plates 210. The conical cylinder 230 has a stirring portion 231 and a transmission portion 234, and the stirring portion 231 is located in the compression chamber 220, and the transmission portion 234 is located in the rotating cylinder 120. The above-mentioned stirring plate 233 is rotatably set on the stirring portion 231 of the conical cylinder 230. A plurality of water holes 232 are opened on the side wall of the stirring portion 231 of the conical cylinder 230. The conical cylinder 230 can rotate around its own axis to drive the stirring plate 233 to rotate and then stir the compression chamber 220 located in the stirring area 130. At the same time, the water holes 232 on the conical cylinder 230 can assist in discharging water in the compression chamber 220.

[0064] More specifically, a connecting ring sleeve 240 is rotatably provided on the conical cylinder 230 in this embodiment, and the stirring plate 233 is connected to the stirring portion 231 through the connecting ring sleeve 240. In the embodiment of the present invention, there are three stirring plates 233, and the three stirring plates 233 are evenly arranged on the stirring portion 231 of the conical cylinder 230 in the circumferential direction, and one end of the three stirring plates 233 is hinged on the connecting ring sleeve 240, and an elastic member 241 is provided between the connecting ring sleeve 240 and the conical cylinder 230, and the elastic member 241 is provided between the connecting ring sleeve 240 and the conical cylinder 230. Component 241 is a torsion spring, one end of which is fixedly connected to the inner wall of the connecting ring sleeve 240, and the other end of which is fixedly connected to the outer wall of the conical cylinder 230. When the conical cylinder 230 rotates around its own axis, since the torsion spring is arranged between the connecting ring sleeve 240 and the conical cylinder 230, the conical cylinder 230 will generate relative rotation with the connecting ring sleeve 240. The rotation of the conical cylinder 230 pulls the torsion spring, and the torsion spring pulls the connecting ring sleeve 240 to rotate, and the connecting ring sleeve 240 drives the three stirring plates 233 to rotate. When the connecting ring sleeve 240 rotates relative to the conical cylinder 230, the three stirring plates 233 are driven to rotate relative to the conical cylinder 230. When the three conical plates rotate relative to the conical cylinder 230, they can block part of the water holes 232 (the three stirring plates 233 do not block the water holes 232 when they do not rotate relative to the conical cylinder 230). The relative rotation distance of the stirring plates 233 on the conical cylinder 230 is negatively correlated with the water content of the slag in the compression chamber 220.

[0065] It can be understood that when the stirring plate 233 rotates in the compression chamber 220, it will be subject to resistance from the slag mixture. When there is more solid matter in the slag mixture, the resistance encountered by the stirring plate 233 increases, thereby increasing the distance that the stirring plate 233 rotates relative to the conical cylinder 230, that is, the stirring plate 233 blocks more water holes 232. If there is more solid matter in the slag mixture, it means that there is less liquid matter. More water holes 232 are blocked to reduce the amount of auxiliary drainage of the conical cylinder 230; when there is less solid matter in the slag mixture, the resistance encountered by the stirring plate 233 is smaller, and the distance that the stirring plate 233 rotates relative to the conical cylinder 230 is smaller. The stirring plate 233 blocks fewer water holes 232. If there is less solid matter in the slag mixture, it means that there is more liquid matter, thereby increasing the amount of auxiliary drainage, and then adaptively adjusting the amount of auxiliary drainage of the conical cylinder 230 according to the content of solid matter in the slag mixture.

[0066] In a further embodiment, a one-way snap-fit ​​assembly is provided on the connecting ring sleeve 240, and the one-way snap-fit ​​assembly enables the connecting ring sleeve 240 to rotate in one direction, thereby fixing the position of the stirring plate 233 on the connecting ring sleeve 240 to block the water hole 232. Since an elastic member 241 is provided between the connecting ring sleeve 240 and the conical cylinder 230, when the conical cylinder 230 rotates and drives the connecting ring sleeve 240 to rotate, the stirring plate 233 is subjected to resistance, causing the connecting ring sleeve 240 and the conical cylinder 230 to rotate relative to each other, while the one-way snap-fit ​​assembly allows the stirring plate 233 to be subjected to resistance, causing the connecting ring sleeve 240 and the conical cylinder 230 to rotate relative to each other, and the one-way snap-fit ​​assembly does not allow the elastic member 241 to pull the connecting ring sleeve 240 to reset. Only when the resistance to the stirring plate 233 increases can the connecting ring sleeve 240 continue to rotate relative to the conical cylinder 230.

[0067] Specifically, Fig.11 As shown, the one-way locking assembly includes a first ratchet ring 250 and a second ratchet ring 251. The first ratchet ring 250 is telescopically arranged on the conical cylinder 230. The first ratchet ring 250 can move along the axial direction of the conical cylinder 230 (a spring is arranged between the first ratchet ring 250 and the conical cylinder 230 for easy resetting), and the second ratchet ring 251 is fixedly arranged on the connecting ring sleeve 240. The first ratchet ring 250 and the second ratchet ring 251 are meshed with each other. When the connecting ring sleeve 240 rotates relative to the conical cylinder 230 to tighten the elastic member 241, the retraction of the first ratchet ring 250 does not restrict the connecting ring sleeve 240, but restricts the connecting ring sleeve 240 from being pulled by the elastic member 241 to rotate in the opposite direction.

[0068] In a further embodiment, in order to realize the rotation of the conical cylinder 230 around its own axis, a fixed sleeve 300 is coaxially and fixedly arranged inside the cylinder body 110, a fixed disk 310 is arranged on the top of the fixed sleeve 300, a conical ring 311 is fixedly arranged on the lower surface of the fixed disk 310, and an engagement ring 235 is fixedly arranged on the transmission part 234 of the conical cylinder 230, and the engagement ring 235 has a conical surface, and the conical surface can be engaged with the conical ring 311, as shown in detail. Fig.15 As shown, when the conical cylinder 230 moves radially outwardly along the rotating cylinder 120 ( Fig.15 The conical cylinder 230 moves to the left), the meshing ring 235 on the conical cylinder 230 is in frictional contact with the conical ring 311. Since the rotating cylinder 120 drives the conical cylinder 230 to revolve along the axis of the rotating cylinder 120, and the fixed sleeve 300 is fixed on the cylinder body 110, when the fixed sleeve 300 and the rotating cylinder 120 rotate relative to each other, the conical cylinder 230 rotates around its own axis. When the conical ring 311 is not in contact with the meshing ring 235, the conical cylinder 230 does not rotate around its own axis when the rotating cylinder 120 drives the conical cylinder 230 to revolve, that is, the stirring plate 233 no longer stirs.

[0069] More specifically, the interior of the fixed sleeve 300 is hollow, and a telescopic rod 320 is arranged inside the fixed sleeve 300. One end of the telescopic rod 320 is fixed in the fixed sleeve 300, and the other end of the telescopic rod 320 is connected to a connecting rod 321. The other end of the connecting rod 321 is connected to the conical cylinder 230, specifically through a connecting sleeve 322. The connecting sleeve 322 is located on the outer circumference of the conical cylinder 230, and an annular groove 323 is opened on the outer circumference of the conical cylinder 230. The connecting sleeve 322 is located in the annular groove 323, and the connecting rod 321 is hinged with the connecting sleeve 322. When the telescopic rod 320 is shortened, the connecting rod 321 pushes the conical cylinder 230 to move radially outward along the rotating cylinder 120 so that the cone rotates around its own axis. When the telescopic rod 320 is extended, the connecting rod 321 pulls the conical cylinder 230 to move radially inward along the rotating cylinder 120 so that the meshing ring 235 on the conical cylinder 230 disengages from the conical ring 311, that is, the conical cylinder 230 no longer rotates around its own axis.

[0070] It should be noted that the connecting rod 321 in the present invention can be passively extended or shortened, which is equivalent to an elastic telescopic rod, and has the following effects:

[0071] If the slag in the compression chamber 220 contains a large amount of solid matter, when the telescopic rod 320 is shortened to drive the conical cylinder 230 to move radially outward along the rotating cylinder 120, the conical head of the conical cylinder 230 encounters greater resistance when inserted into the compression chamber 220. To avoid forced insertion, the connecting rod 321 can be used for buffering, that is, the connecting rod 321 is shortened after being subjected to the force, thereby avoiding damage to the head of the conical cylinder 230.

[0072] In a further embodiment, a driving assembly 600 is disposed inside the cylinder 110, and the driving assembly 600 is used to drive the rotating cylinder 120 to rotate. The driving assembly 600 includes a driving motor 610, and the driving motor 610 is fixedly disposed on the supporting ring frame 100. The gear of the driving motor 610 drives the rotating cylinder 120 to rotate.

[0073] It should be noted that the driving component 600 is not limited to the above structure, but can also be other driving elements, which are not specifically limited here.

[0074] In a further embodiment, a negative pressure assembly is provided inside the conical cylinder 230, and the negative pressure assembly enables the water holes 232 on the surface of the conical cylinder 230 to actively absorb the liquid in the compression chamber 220. The negative pressure assembly includes a push-pull rod 430 and a piston 440. The piston 440 is slidably provided inside the conical cylinder 230. When the piston 440 moves axially along the conical cylinder 230, the pressure inside the conical cylinder 230 can be changed. The push-pull rod 430 is connected to the piston 440. A slide rail 330 is provided on the outer peripheral wall of the fixed sleeve 300, and the slide rail 330 surrounds the fixed sleeve 300. , and the slide rail 330 is in the same plane. The shape of the slide rail 330 in the auxiliary drainage area 140 is wavy, and one end of the push-pull rod 430 is slidably set in the slide rail 330. When the rotating cylinder 120 drives the conical cylinder 230 to revolve around the axis of the rotating cylinder 120, one end of the push-pull rod 430 slides in the slide rail 330. When one end of the push-pull rod 430 slides to the wavy part 331 of the slide rail 330, the push-pull rod 430 moves along the axial direction of the conical cylinder 230 to push and pull the piston 440, thereby changing the air pressure inside the conical cylinder 230.

[0075] Specifically, a water collecting chamber 410 is provided in the conical cylinder 230 near the water through hole 232. Fig.13 As shown, three arc plates 400 are arranged in the conical cylinder 230, and the three arc plates 400 divide the three areas with water holes 232 on the conical cylinder 230 into three water collecting chambers 410. The liquid in the compression chamber 220 can enter the water collecting chamber 410 through the water holes 232 on the side wall of the conical cylinder 230. The three arc plates 400 are all provided with one-way water outlets 411 at positions close to the axis of the conical cylinder 230. The one-way water outlets 411 only allow liquid to enter the conical cylinder 230 from the water collecting chamber 410. An air pipe 420 is arranged at the axis position in the conical cylinder 230, and a one-way air vent 421 is provided on the side wall of the air pipe 420. The one-way air vent 421 only allows gas to enter the air pipe 420. When one end of the push-pull rod 430 passes through the wavy portion 331 of the slide rail 330, the push-pull rod 430 The pull rod 430 pulls the piston 440, and negative pressure is generated in the conical cylinder 230. The liquid in the water collecting chamber 410 will enter the conical cylinder 230 from the water collecting chamber 410 through the one-way water outlet 411. A drain port 236 is provided on the side wall of the conical cylinder 230 located in the rotating cylinder 120. The liquid enters the rotating cylinder 120 through the drain port 236. A waste water port 122 is provided on the rotating cylinder 120. The liquid is discharged through the waste water port 122. When the push-pull rod 430 pushes the piston 440, the gas in the conical cylinder 230 enters the air pipe 420 through the one-way vent 421 on the air pipe 420, and the gas is discharged from the air pipe 420. The push-pull rod 430 reciprocates to pull the piston 440, thereby realizing the function of continuously extracting the liquid in the compression chamber 220, thereby further reducing the content of liquid substance in the compression chamber 220.

[0076] It should be noted that a spring is provided between the push-pull rod 430 and the piston 440 in this embodiment to avoid damage to the piston 440 and the push-pull rod 430 .

[0077] In a further embodiment, a semi-annular plate 530 is provided at the discharge port 112 of the holding zone 150, and a discharge groove 531 is provided on the semi-annular plate 530. The shape of the discharge port 112 is an annular groove 323. The size of the discharge groove 531 is smaller than the size of the annular groove 323, and the semi-annular plate 530 can slide along the annular groove 323 to change the position of the discharge groove 531. The slag passing through the holding zone 150 will be discharged through the discharge groove 531. When the semi-annular plate 530 moves along the annular groove 323 to change the position of the discharge groove 531, the slag in the holding zone The time that the slag exists in the pressure holding zone 150 will be different. For example, when the distance moved by the semi-annular plate 530 is less, the discharge chute 531 is closer to the slag in the pressure holding zone 150, and the slag is discharged from the discharge chute 531 not long after entering the pressure holding zone 150. The time that the slag exists in the pressure holding zone 150 is shorter. When the distance moved by the semi-annular plate 530 is greater, the distance between the slag and the discharge chute 531 is greater, and the slag needs to move a longer distance in the pressure holding zone 150 to reach the discharge chute 531 to complete the discharge, thereby making the slag exist in the pressure holding zone 150 for a longer time.

[0078] It should be noted that the volume of the compression chamber 220 in the pressure holding area 150 is the same but smaller than the volume of the compression chamber 220 in the stirring area 130 and the auxiliary drainage area 140. The slag entering the pressure holding area 150 is filtered through the stirring area 130 and the auxiliary drainage area 140, so the slag in the pressure holding area 150 has a relatively low water content. At this time, when the conical cylinder 230 moves radially outward along the rotating cylinder 120 in the compression chamber 220 under the action of the telescopic rod 320, the distance that the conical cylinder 230 is inserted into the slag is relatively short. The lower the water content of the slag, the shorter the distance inserted into the slag. The water content of the slag can be judged by judging the length of the conical cylinder 230 inserted into the slag.

[0079] Specifically, the movement of the semi-annular plate 530 on the annular groove 323 of the present invention is achieved by a linkage assembly 500, which includes a rotating rod 520, a stopper 510 and a spring. Figure 6As shown, the limit block 510 is fixedly arranged on the plane where the discharge port 112 is located, and the rotating rod 520 is spirally connected to the limit block 510. A part of the rotating rod 520 extending out of the limit block 510 is frictionally abutted against the lower surface of the semi-annular plate 530, and the other part of the rotating rod 520 extending out of the limit block 510 is connected to the spring. The spring enables the rotating rod 520 to have a reset function, and the rotating rod 520 is made of permanent magnetic material. The first magnet 260 is fixedly connected to the conical cylinder 230. When the conical cylinder 230 moves to a position close to the discharge port 112, the rotating rod 520 can be pulled to move in a direction close to the rotating cylinder 120 under the action of magnetic force. Since the limit block 510 and the rotating rod 520 are spirally connected, the rotating rod 520 rotates around its own axis, and the rotating rod 520 is in frictional contact with the lower surface of the semi-annular plate 530, thereby driving the semi-annular plate 530 to move.

[0080] It can be understood that if the moisture content of the slag in the pressure holding zone 150 is low, the length of the conical cylinder 230 inserted into the compression chamber 220 is short, and thus the distance from the rotating rod 520 is long. The first magnet 260 on the conical cylinder 230 is long from the rotating rod 520, and the magnetic force is weak, so that the distance the rotating rod 520 moves toward the rotating cylinder 120 is short, which means that the number of turns of the rotating rod 520 is small, thereby driving the semi-annular plate 530 to move closer, and the discharge trough 531 is closer to the slag. The slag enters the pressure holding zone 150 for a short time and then is discharged from the discharge trough 531, that is, the slag with less moisture content is discharged from the compression chamber 220 in advance. Similarly, if the moisture content of the slag in the pressure holding zone 150 is high, the conical cylinder 230 is short. The length of the cylinder 230 inserted into the compression chamber 220 will increase, so that the distance to the rotating rod 520 is closer. The first magnet 260 on the conical cylinder 230 is closer to the rotating rod 520 and has a stronger magnetic force, so that the rotating rod 520 moves a longer distance in the direction close to the rotating cylinder 120, which means that the rotating rod 520 rotates a greater number of times, driving the semi-annular plate 530 to move a greater distance, so that the discharge trough 531 is farther away from the slag, extending the time required for the slag to move to the discharge trough 531. During this time, the moisture in the slag can also be discharged through the water holes 232 on the side wall of the conical trough, thereby reducing the water content of the slag. When the slag moves to the discharge trough 531, the water content of the slag has been reduced to a stable value, so the slag is discharged.

[0081] By setting the above structure, when the slag is about to be discharged, it is drained for the last time according to its water content, thereby ensuring that the water content of the discharged slag is similar, which is convenient for subsequent processing of the slag.

[0082] In a further embodiment, a second magnet 340 is provided on the fixed disk 310 near the discharge port 112, and the second magnet 340 is used to attract the conical cylinder 230 to move toward the direction close to the axis of the rotating cylinder 120 when moving from the pressure holding area 150 to the discharge port 112, thereby allowing the connecting ring sleeve 240 to break away from the restriction of the one-way limit assembly, so that the connecting ring sleeve 240 is reset, and the stirring plate 233 is also reset.

[0083] The specific working process of a slag separation and recovery device for mica pulping provided by the present invention is described below in combination with the above embodiments:

[0084] The driving motor 610 is started, and the driving motor 610 drives the rotating cylinder 120 to rotate. At the same time, the telescopic rod 320 reciprocates to drive the conical cylinder 230 to reciprocate along the radial direction of the rotating cylinder 120 .

[0085] The slag-material mixture is added to the feed port 111, and the slag-material mixture enters the compression chamber 220 from the feed port 111. The rotating cylinder 120 rotates to drive the plurality of telescopic plates 210 to revolve around the rotating cylinder 120. As the distance between the spiral plate 200 and the outer wall of the rotating cylinder 120 gradually shortens, the volume of the compression chamber 220 between two adjacent telescopic plates 210 gradually decreases. The rotating cylinder 120 is provided with a through hole 121, and the slag-material mixture in the compression chamber 220 is squeezed and discharged from the through hole 121.

[0086] When the telescopic rod 320 is shortened, the connecting rod 321 drives the conical cylinder 230 to move radially outward along the rotating cylinder 120 to be inserted into the compression chamber 220, and the meshing ring 235 on the transmission part 234 of the conical cylinder 230 meshes with the conical ring 311 on the fixed disk 310, so that the rotating cylinder 120 drives the conical cylinder 230 to revolve while the conical cylinder 230 rotates around its own axis. The stirring part 231 of the conical cylinder 230 drives the connecting ring sleeve 240 to rotate through the elastic member 241, and the connecting ring sleeve 240 drives the stirring plate 233 to rotate, thereby stirring the slag-material mixture in the compression chamber 220, so that the slag-material mixture is mixed evenly while preventing the solid matter in the slag-material mixture from clogging the through hole 121, and a water hole 232 is provided on the side wall of the stirring part 231 of the rotating cylinder 120, and part of the liquid can also be discharged through the water hole 232.

[0087] The resistance of the slag mixture encountered by the stirring plate 233 when rotating in the compression chamber 220 is related to the content of solid matter in the slag. The higher the content of solid matter, the greater the resistance encountered by the stirring plate 233. The connecting ring sleeve 240 will pull the elastic member 241 and the conical cylinder 230 to produce relative rotation. When the stirring plate 233 rotates, it can block part of the water holes 232, thereby reducing the amount of auxiliary drainage of the conical cylinder 230. At the same time, the one-way locking assembly on the connecting ring sleeve 240 only allows the connecting ring sleeve 240 to tighten the elastic member 241 and rotate, thereby preventing the stirring plate 233 from resetting when there is no resistance.

[0088] When the compression chamber 220 enters the auxiliary drainage area 140, the liquid matter in the slag in the compression chamber 220 is greatly reduced, and the proportion of solid matter increases, making it more difficult for the conical cylinder 230 to be inserted into the solid matter. The telescopic rod 320 shortens and drives the conical cylinder 230 to move radially outward along the rotating cylinder 120, reducing the distance. Through the action of the connecting rod 321, the telescopic rod 320 is prevented from forcibly driving the conical cylinder 230 to move radially outward along the rotating cylinder 120, thereby preventing the conical cylinder 230 from being damaged. One end of the push-pull rod 430 in the conical cylinder 230 moves in the slide rail 330 on the outer periphery of the fixed sleeve 300. After entering the auxiliary drainage area 140, one end of the push-pull rod 430 enters the wavy part 331 of the slide rail 330. As the rotating cylinder 120 rotates, the push-pull rod 430 pulls the piston 440 back and forth, so that the piston 440 in the conical cylinder 230 changes the pressure inside the conical cylinder 230.

[0089] When the piston 440 moves toward the direction approaching the axis of the rotating cylinder 120, negative pressure is generated inside the stirring portion 231 of the rotating cylinder 120, and the liquid in the water collecting chamber 410 on the water hole 232 enters the conical cylinder 230 through the one-way water outlet 411. The conical cylinder 230 is provided with a drain port 236, and the liquid enters the rotating cylinder 120 through the drain port 236. The rotating cylinder 120 is provided with a waste water port 122, and the liquid is discharged from the waste water port 122. When the piston 440 moves away from the axis of the rotating cylinder 120, the gas in the conical cylinder 230 enters the air pipe 420 from the one-way air hole 421 of the air pipe 420, and the gas is discharged from the air pipe 420, thereby completing the function of assisting the discharge of liquid in the solid substance again, and further reducing the water content in the fixed substance.

[0090] As the rotating cylinder 120 rotates, the compression chamber 220 enters the pressure holding area 150, and the volume of the compression chamber 220 in the pressure holding area 150 does not change. The water content of the solid material in the compression chamber 220 is very low. The distance the conical cylinder 230 is inserted into the solid material is related to the water content of the solid material. If the water content in the solid material is very low, the distance the conical cylinder 230 is inserted into the solid material is very short, so that the farther the first magnet 260 on the conical cylinder 230 is from the rotating rod 520 near the discharge port 112, the weaker the magnetic force between the first magnet 260 and the rotating rod 520, and the shorter the distance the rotating rod 520 moves in the direction close to the rotating cylinder 120, that is, the fewer turns the rotating rod 520 rotates under the spiral connection of the limit block 510, and the shorter the rotation of the semi-annular plate 530 driven by the rotating rod 520 The distance is shorter, and the discharge groove 531 on the semi-annular plate 530 moves a shorter distance, so that the slag in the holding zone 150 is discharged in advance; if the water content in the solid material is higher than the above, the distance that the conical cylinder 230 is inserted into the solid material is longer, so that the first magnet 260 on the conical cylinder 230 is closer to the rotating rod 520 near the discharge port 112, the magnetic force between the two is stronger, the rotating rod 520 moves a longer distance toward the rotating cylinder 120, and the number of circles of rotation of the rotating rod 520 is greater, thereby increasing the distance that the rotating rod 520 drives the semi-annular plate 530 to move, thereby increasing the residence time of the slag in the holding zone 150 in the compression chamber 220, so that part of the water in the solid material can have time to be discharged, further improving the uniformity of the water content of the discharged slag.

[0091] After the discharge is completed, the rotating cylinder 120 drives the conical cylinder 230 away from the pressure holding area 150. When the telescopic rod 320 is extended, the connecting rod 321 on the telescopic rod 320 pulls the conical cylinder 230 to reset. When the telescopic rod 320 is extended to the longest, the connecting rod 321 is reset. At this time, the stirring plate 233 on the conical cylinder 230 just fits on the side wall of the rotating cylinder 120 passing through. Since the second magnet 340 is provided at the position close to the discharge port 112, the second magnet 340 attracts the conical cylinder 230 to move radially inward along the rotating cylinder 120 to overcome the connecting rod 321. The force of the connecting rod 321 is exerted, and the stirring plate 233 is attached to the side wall, so that the connecting ring sleeve 240 moves axially relative to the conical cylinder 230, and moves in the direction away from the axis of the rotating cylinder 120, thereby contacting the restriction of the one-way clamping component, so that the connecting ring sleeve 240 is reset under the reset of the elastic member 241, and then the stirring plate 233 is reset, and the stirring no longer blocks the water hole 232 on the side wall of the conical cylinder 230, and the slag mixture continues to enter from the feed port 111, and the above process is continuously circulated to complete the filtration of the slag.

[0092] The present invention also provides a slag separation and recovery process for mica pulping, which specifically comprises the following specific steps:

[0093] S100: slag wastewater collection;

[0094] The slag wastewater generated during the mica pulping process is collected in a wastewater pool, which contains mica powder, silt and other impurities. In order to ensure the efficiency of the subsequent separation process, preliminary screening is required to remove large particles of impurities and solids.

[0095] S200: filter press;

[0096] The equipment used for the filter press is a slag separation and recovery equipment for mica pulping provided by the present invention, which removes moisture from the slag to obtain a mica powder filter cake with a low moisture content. This step can not only reduce wastewater discharge, but also ensure the recovery rate and purity of the mica powder.

[0097] S300: Drying treatment;

[0098] The mica powder cake after filtration enters the drying equipment for low-temperature drying to remove residual moisture. The dried mica powder can be directly used for reproduction to achieve resource recycling.

[0099] S400: Wastewater treatment;

[0100] Wastewater still contains a small amount of suspended matter and chemicals, which require further purification. Usually, flocculation sedimentation, filtration or other chemical treatment methods are used to remove impurities in wastewater. The treated wastewater can meet the discharge standards, and part of the water can be reused in the production process.

[0101] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0102] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
