Description

Technical Field

[0001] This invention relates to the field of solid material dewatering technology, and more specifically to a vacuum dewatering system for solid material production. Background Technology

[0002] In the large-scale production process of a certain solid material in China, a key step is the efficient separation of the mixed suspension formed with a large amount of solvent and water. This water displacement (dehydration) process directly determines the water content, physical state, subsequent processing efficiency, and storage safety of the final solid material product, and is the cornerstone for ensuring the stability of later product performance and the reliability of weapon systems.

[0003] For a long time, the domestic technology for driving water out of solid materials has generally adopted centrifugal water removal technology, mainly using centrifuges to remove water from the solid material suspension. Although this technology meets production needs to a certain extent, it still has the following disadvantages: 1) High moisture content, resulting in a heavy burden on subsequent drying; 2) Centrifugal water removal causes serious mechanical damage to the material, resulting in poor material integrity; 3) The process is segmented and intermittent, requiring manual feeding, resulting in poor process continuity.

[0057] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0058] like Figures 1-20As shown, one embodiment of the present invention provides a vacuum water-driving system for solid material production, including a feeding mechanism 13, a distributing mechanism 11, a water separator 7, multiple receiving hoppers 12, multiple conveying pipes, and at least one suction pipe; the receiving hopper 12 is equipped with at least one strainer 121 for separating water and solid materials, and the bottom of the receiving hopper 12 has a discharge port, which is lower than the strainer 121; the water separator 7 has multiple mutually isolated drainage channels evenly arranged around its axis, and the water separator 7 has a liquid storage chamber inside, which is lower than the drainage channels and connected to the drainage channels. The channels are interconnected. One end of the suction pipe is connected to the liquid storage chamber, and the other end is used to connect to the vacuum unit. The drain channel, the conveying pipe and the receiving hopper 12 correspond one-to-one. One end of the conveying pipe is connected to the discharge port on the corresponding receiving hopper 12, and the other end is connected to the corresponding drain channel. The vacuum unit is used to extract wastewater from the receiving hopper 12 and remove moisture from the solid materials in the receiving hopper 12. The distributing mechanism 11 is used to feed solid material suspension into multiple receiving hoppers 12. The feeding mechanism 13 is used to supply solid material suspension to the distributing mechanism 11.

[0059] In this embodiment, the feeding mechanism 13 supplies the solid material suspension to the distributing mechanism 11, and then the distributing mechanism 11 puts the solid material suspension into multiple receiving hoppers 12. Then, the vacuum unit is turned on, and the vacuum unit provides vacuum pressure. Under the action of vacuum and screen 121, the suspension is separated into solid material and wastewater. The wastewater passes through the screen 121 and is discharged under vacuum suction, while the solid material remains above the screen 121. Under the continuous action of vacuum pressure, the moisture content of the material can be reduced by 25% compared with the centrifugal water removal method.

[0060] It is evident that the vacuum water-driving system for solid material production can efficiently separate waste liquid from solid materials, while reducing the moisture content of the solid materials. Furthermore, the solid materials produced using this vacuum water-driving method exhibit high integrity. In addition, the system requires no manual feeding, ensuring strong process continuity.

[0061] It should be noted that the vacuum unit includes a negative pressure tank 23 and a vacuum pump. The negative pressure tank 23, for example... Figure 20 As shown, the negative pressure tank 23 has a connecting pipe 231 at the top, a drain pipe 233 on one side of its bottom, and a vacuum connection pipe 232 on its side wall near the top. The connecting pipe 231 is used to connect to the suction filter pipe, while the vacuum connection pipe 232 is used to connect to the vacuum pump. The drain pipe 233 is used for drainage. Electrically controlled valves are installed on the connecting pipe 231, the drain pipe 233, and the vacuum connection pipe 232.

[0062] Before vacuum water removal, a vacuum pump extracts air from the negative pressure tank 23 to create a negative pressure state. During vacuum water removal, the electrically controlled valves on the vacuum connection pipe 232 and the drain pipe 233 are closed. Then, the electrically controlled valve on the connecting pipe 231 is opened. Under the action of negative pressure, the waste liquid in the receiving hopper 12 is drawn into the negative pressure tank 23. At the same time, under the continuous action of vacuum pressure, the moisture content of the solid material gradually decreases. It should be noted that this negative pressure tank 23 is a large vacuum tank, which can sustain water removal operations for several hours with a single vacuuming operation.

[0063] In this embodiment, the dispensing mechanism 11 includes a dispensing bucket 111 and multiple discharge pipes 113. The dispensing bucket 111 is located above the annular box 6. A cylinder is fixedly installed at the center of the bottom wall of the dispensing bucket 111. An annular cavity is formed between the cylinder and the inner wall of the dispensing bucket 111. The annular cavity is evenly divided into multiple liquid storage chambers by multiple partitions 112. Each liquid storage chamber has two bottom plates at its bottom. For ease of description, these two bottom plates are named as follows: A first base plate 114 and a second base plate 115 are provided, sealing the bottom opening of the liquid storage chamber. The end of each base plate closer to the cylinder is higher than the other end. Furthermore, the included angle formed between the first base plate 114 and the second base plate 115 is an obtuse angle. Multiple discharge ports are evenly distributed around the axis of the dispensing tank 111 on its outer circumference. Each discharge port corresponds to a liquid storage chamber, and the discharge ports are directly opposite the included angle between the first base plate 114 and the second base plate 115. The liquid storage chamber, the discharge pipe 113, and the receiving hopper 12 are also corresponding. One end of the discharge pipe 113 is connected to its corresponding liquid storage chamber, and its other end is located above its corresponding receiving hopper 12.

[0064] When the suspension enters the storage chamber, because the end of the two bottom plates closest to the cylinder is higher than the other end, the suspension will gradually flow outward from the center of the distribution tank 111 under the influence of gravity. Furthermore, since the angle formed between the first bottom plate 114 and the second bottom plate 115 is obtuse, the suspension will gradually gather at the angle between the first bottom plate 114 and the second bottom plate 115, and finally flow out along the angle between the first bottom plate 114 and the second bottom plate 115 into the corresponding discharge pipe 113. This accelerates the discharge rate of the suspension, ensuring that the suspension in the storage chamber can directly flow into the discharge pipe 113, and preventing liquid accumulation in the storage chamber; all the suspension can be smoothly discharged into the discharge pipe 113.

[0065] In this embodiment, as Figure 15As shown, the receiving hopper 12 is cylindrical, with a screen 121 horizontally installed on its inner wall. Below the screen 121, an inclined plate 122 is installed, tilted at an acute angle with the screen 121. A discharge port is located on the side wall of the receiving hopper 12, lower than the screen 121. The inclined plate 122 facilitates the discharge of wastewater into the conveying pipe.

[0066] In this embodiment, it also includes a support base 1, a support cylinder 2, a support frame 4, an annular box 6, a main shaft 8, and a drive device.

[0067] In this embodiment, as Figure 5 As shown, the support base 1 includes a support plate 101 and multiple support legs 102. The support plate 101 is fixedly installed on the top of the support legs 102, and a hole for the main shaft 8 to pass through is opened at the center of the support plate 101. Multiple support columns 3 are evenly arranged around the axis of the support plate 101 on the top of the support plate 101. The support cylinder 2 is fixedly installed on the top of the multiple support columns 3. The support cylinder 2 is a cylinder with an opening at the top and a hole for the main shaft 8 to pass through on its inner bottom wall.

[0068] Furthermore, such as Figure 4 and Figure 7 As shown, the support frame 4 is installed inside the support cylinder 2. The support frame 4 includes a support ring 402 and multiple columns 401. The multiple columns 401 are vertically fixed to the inner bottom wall of the support cylinder 2 and are evenly arranged around the axis of the support cylinder 2. The support ring 402 is fixed to the multiple columns 401 and is coaxial with the support cylinder 2. A first bearing 5 is installed between the top of the support ring 402 and the bottom of the annular box 6. The annular box 6 acts on the support frame 4 and can rotate relative to the support frame 4.

[0069] In this embodiment, the water distributor 7 is located inside the annular box 6 and includes a top head 701 and a discharge base that are rotatably connected. The top head 701 is located at the upper end of the discharge base. The discharge channel of the water distributor 7 is set on the top head 701 and the discharge channel is an L-shaped channel 706. The L-shaped channel 706 has a connected inlet 704 and an outlet 705. The inlet 704 of the L-shaped channel 706 is located on the circumferential surface of the top head 701, and the outlet 705 of the L-shaped channel 706 is located on the bottom surface of the top head 701.

[0070] Discharge base such as Figure 12 , Figure 13 and Figure 14As shown, it includes a chassis 703 and a disc 702 fixed to the top of the chassis 703. The top of the disc 702 has a circular groove, and a cylindrical protrusion is integrally formed on the top of the disc 702. Two arc-shaped holes 707 are formed through the cylindrical protrusion, and the two arc-shaped holes 707 are symmetrically arranged about the axis of the disc 702. Figure 12 As shown, an annular body is provided at the bottom of the top head 701, and the outlet 705 of the L-shaped channel 706 is located on this annular body. The outer diameter of the annular body is the same as the outer diameter of the cylindrical protrusion, and the end faces of the annular body of the top head 701 and the cylindrical protrusion of the disk 702 are sealed. Figure 13 As shown, an arc-shaped cavity 712 is provided at the bottom of the chassis 703, located directly below the two arc-shaped holes 707. Two drainage holes 713 are provided on the inner bottom wall of the arc-shaped cavity 712, and one end of the filtration tube is sealed and installed inside the drainage hole 713. Furthermore, shaft holes for the main shaft 8 to pass through are provided at the center of the top head 701, the disc 702, and the chassis 703.

[0071] In this embodiment, as Figure 7 As shown, an anti-rotation pin 9 is vertically installed at the bottom of the discharge base, and an anti-rotation baffle 10 is fixedly installed at the bottom of the first bearing 5. The anti-rotation pin 9 is inserted into the anti-rotation baffle 10 to prevent the discharge base from rotating.

[0072] In this embodiment, as Figure 4 As shown, a fixed frame 103 is fixedly installed at the bottom of the support plate 101 of the support base 1. The drive device includes a gearbox 16 and a servo motor 15. The gearbox 16 is fixedly installed on the fixed frame 103, and the servo motor 15 is connected to the input end of the gearbox 16. The spindle 8 is vertically arranged, and the bottom end of the spindle 8 is connected to the output end of the gearbox 16 through a coupling.

[0073] Furthermore, a circular plate is fixedly installed at the top opening of the annular box 6. The main shaft 8 passes sequentially through the base 703, the disc 702, the top head 701, and the top plate. The main shaft 8 is connected to the top plate and the top head 701 of the water distributor 7 by a fixing pin. One end of the conveying pipe is connected to the discharge port of the receiving hopper 12, and the other end passes through the annular box 6 and is connected to the inlet 704 on the circumference of the top head 701. It should be noted that the bottom of the distributing bucket 111 in the distributing mechanism 11 is fixed to the top surface of the annular box 6.

[0074] When the servo motor 15 and the gearbox 16 are started to drive the spindle 8 to rotate, the spindle 8 will drive the annular box 6, the material distribution mechanism 11, the top 701 of the water distributor 7, as well as multiple conveying pipes and receiving hoppers 12 to rotate synchronously around the axis of the spindle 8.

[0075] One advantage of this design is that when the feeding mechanism 13 feeds the material into the distribution tank 111, the distribution tank 111 can rotate with the main shaft 8. Therefore, as the distribution tank 111 rotates, the suspension discharged from the feeding mechanism 13 will evenly enter each storage chamber, instead of supplying the suspension to each storage chamber separately.

[0076] In this embodiment, a flipping drive mechanism is also included, which is used to drive the receiving hopper 12 to flip and reset.

[0077] Specifically, such as Figure 7 , Figure 9 , Figure 15 and Figure 16 As shown, the tilting drive mechanism includes multiple lifting gear mechanisms 14, multiple gears 192 and multiple rollers 142, with each of the lifting gear mechanism 14, gears 192, conveying pipe and receiving hopper 12 corresponding to one another.

[0078] like Figure 5 and Figure 6 As shown, a V-shaped notch 202 is formed on a small section of the circumferential surface of the bearing cylinder 2. A grooved plate 203 is fixedly installed inside the V-shaped notch 202 via an arc-shaped plate 201. The arc-shaped plate 201 is fixedly installed on the circumferential surface of the bearing cylinder 2, and the grooved plate 203 is fixedly installed on the inner wall of the arc-shaped plate 201, with the grooved plate 203 located inside the V-shaped notch 202. A V-shaped channel is formed between the grooved plate 203 and the inner wall of the V-shaped notch 202. The top surface of the grooved plate 203 is higher than the top surface of the bearing cylinder 2, and the lower half of the grooved plate 203 extends into the V-shaped notch 202. Figure 6 As can be seen, the groove plate 203 is also arc-shaped, and from the front view of the groove plate 203, the groove plate 203 is triangular.

[0079] Furthermore, a gear 192 is fixedly installed on the circumference of each conveying pipe, and the gear 192 is located in the internal space of the annular box 6. The lifting gear mechanism 14 includes a lower tube 141 and a lifting column 143. The annular box 6 has multiple straight holes around its axis, and the straight holes are arranged along the axial direction of the annular box 6. The lower tube 141 is fixedly installed at the bottom of the annular box 6 and communicates with the straight holes. A guide sleeve 144 is fixedly installed at the top of the straight holes in the annular box 6. The bottom end of the lifting column 143 passes through the guide sleeve 144 and extends into the interior of the lower tube 141. Furthermore, a strip-shaped hole 145 is opened on the side of the lower tube 141, and the length direction of the strip-shaped hole 145 is the same as the axial direction of the lower tube 141. A wheel axle is installed on the bottom circumference of the lifting column 143. The wheel axle passes through the strip-shaped hole 145, and a roller 142 is installed at the end of the wheel axle away from the lifting column 143.

[0080] It should be noted that a long groove is provided on the circumference of the lifting column 143. The inner wall of the groove is flat, and a vertically arranged toothed plate is installed on the flat surface. The toothed plate meshes with the gear 192 on the conveying pipe.

[0081] like Figure 7 As shown, the roller 142 at the bottom of the lifting column 143 rests on the top end face of the bearing cylinder 2.

[0082] When the main shaft 8 drives the annular box 6 and the top 701 of the water distributor 7 to rotate together, the conveying pipe and the receiving hopper 12 will rotate together around the axis of the main shaft 8, while the roller 142 at the bottom of the lifting column 143 travels around the axis of the bearing cylinder 2 on the top circumference of the bearing cylinder 2. When the roller 142 at the bottom of a certain lifting column 143 just enters the V-shaped notch 202 and moves downward, the lifting column 143 automatically falls. Since the toothed plate on the lifting column 143 meshes with the gear 192 on the conveying pipe, the conveying pipe will flip as the lifting column 143 falls. When the roller 142 at the bottom of the lifting column 143 enters the lowest position of the V-shaped notch 202, the conveying pipe will flip 180°, that is, the receiving hopper 12 will flip 180° from top to bottom, thereby emptying the solid material in the receiving hopper 12. As the main shaft 8 drives the top 701 of the annular box 6 and the water distributor 7 to continue rotating, the roller 142 at the bottom of the lifting column 143 begins to move upward. As the roller 142 moves upward along the V-shaped channel, the lifting column 143 gradually rises, thereby driving the conveying pipe to rotate in the opposite direction. That is to say, the receiving hopper 12 begins to reset. Until the roller 142 just moves out of the V-shaped channel, the receiving hopper 12 reverses 180° and completes the reset.

[0083] This enables automated material feeding, eliminating the need for manual removal of solid materials from the receiving hopper 12, greatly improving work efficiency and production capacity, while also saving time and effort.

[0084] In some embodiments, a sealing cover 191 is installed on the circumferential surface of the conveying pipe, and the gear 192 is covered inside the sealing cover 191. A through hole is provided on the circumferential surface of the sealing cover 191, and the lifting column 143 meshes with the gear 192 through the through hole.

[0085] In this embodiment, to avoid material sticking when the receiving hopper 12 rotates 180° to complete the unloading action, a back-blowing mechanism is specially provided. The back-blowing mechanism includes a blower pump and a blower pipe 20.

[0086] like Figure 13 and Figure 14As shown, a first purge hole 708 and a second purge hole 710 are respectively provided on the cylindrical protrusion of the disk 702 and on the base 703. The first purge hole 708 and the second purge hole 710 are coaxially arranged. One end of the purge pipe 20 is connected to the second purge hole 710, and the other end is connected to the purge pump.

[0087] It needs to be explained that when a receiving hopper 12 has rotated 180° from top to bottom, the outlet 705 on the top head 701 corresponding to the conveying pipe is rotated to be directly above the first purging hole 708. At this time, the purging pump starts to perform back purging. Compressed gas enters the purging pipe 20 and passes through the second purging hole 710 and the first purging hole 708 in sequence before entering the corresponding L-shaped channel 706. Finally, it enters the receiving hopper 12, which has rotated 180°, from the conveying pipe, thereby cleaning the material stuck on the strain net 121 and thus avoiding the problem of material sticking.

[0088] In this embodiment, after the hopper 12 is filled with suspension, the electric valve on the connecting pipe 231 is opened. Under the combined action of vacuum negative pressure and the strainer 121, the waste liquid and air pass through the strainer 121 and flow into the conveying pipe. Then, it enters the L-shaped channel 706 of the top head 701, and then is discharged from the bottom outlet 705 of the L-shaped channel 706 into the arc-shaped hole 707 of the disc 702. Next, it flows from the arc-shaped hole 707 into the arc-shaped cavity 712 of the bottom plate 703, and finally flows from the drain hole 713 into the suction pipe, and then enters the negative pressure tank 23 through the suction pipe.

[0089] It should be noted that there is a dynamic seal between the bottom surface of the cylindrical part of the top head 701 and the top surface of the cylindrical protrusion of the disk 702. Specifically, as shown... Figure 8 As shown, a bushing 801, a bottom sleeve 803, and a top sleeve 805 are sequentially installed on the main shaft 8 below the water distributor 7. The heights of the bushing 801, bottom sleeve 803, and top sleeve 805 increase sequentially. The bushing 801 is fixedly installed on the main shaft 8. A second bearing 802 is installed between the bushing 801 and the bottom sleeve 803, allowing the bottom sleeve 803 to rotate relative to the bushing 801. A third bearing 806 is installed between the inner top wall of the top sleeve 805 and the outer circumferential surface of the main shaft 8. The third bearing 806 is sleeved on the main shaft 8, and the top sleeve 805 contacts the inner wall of the third bearing 806, allowing the top sleeve 805 to move axially relative to the main shaft 8. Furthermore, a ring is integrally formed on the outer circumferential surface of the top sleeve 805, which acts on the bottom surface of the chassis 703. A spring 804 is installed between the top sleeve 805 and the bottom sleeve 803.

[0090] It should be clarified that the spring 804 is always in a compressed state. The spring 804 exerts an upward force on the top sleeve 805. Since the ring of the top sleeve 805 acts on the bottom surface of the chassis 703, the chassis 703 is always subjected to an upward force. Under the action of this force, the bottom surface of the bottom cylinder of the top head 701 and the top surface of the cylindrical protrusion of the disc 702 are in close contact, thereby achieving a good sealing effect and preventing air leakage during operation. This type of seal is currently only suitable for the vacuum negative pressure operating environment of this equipment and is not applicable to other positive pressure or normal pressure seals.

[0091] To prevent water from leaking into the device due to leakage between the contact surfaces of the top head 701 and the disc 702, such as... Figure 14 As shown, a first overflow hole 709 and a second overflow hole 711 are respectively provided on the disk 702 and the base 703. The distance between the first overflow hole 709 and the axis of the disk 702 is greater than the distance between the first purging hole 708 and the axis of the disk 702. The first overflow hole 709 is located on the outside of the cylindrical protrusion. One end of the overflow pipe 18 is connected to the second overflow hole 711, and the other end extends out of the device.

[0092] Thus, when water leaks between the contact surfaces of the top head 701 and the disc 702, it can be discharged through the overflow pipe 18.

[0093] In some embodiments, such as Figure 2 and Figure 3 As shown, a first protective cover 104 is installed at the edge of the support plate 101. The first protective cover 104 is composed of multiple arc-shaped protective plates, which are fixed to the support leg 102 with screws. In this way, when it is necessary to repair or maintain the internal gearbox 16, one or more arc-shaped protective plates can be removed.

[0094] In some embodiments, such as Figure 2 and Figure 3 As shown, a second protective cover 22 is installed at the bottom edge of the annular box 6. The second protective cover 22 is also composed of multiple arc-shaped protective plates, which are fixed to the annular box 6 with screws.

[0095] In this embodiment, it should be noted that the feeding mechanism 13 is usually located on the second floor of the main steel structure frame, while the equipment below the feeding mechanism 13 is located on the first floor of the main steel structure frame.

[0096] like Figure 17 and Figure 18As shown, the feeding mechanism 13 includes a support base 131, a feed pipe 138, a feed bend 1310, a swing plate 136, and a transverse drive mechanism. A support platform 137 is mounted on the support base 131, and the feed pipe 138 is mounted on top of the support platform 137. The outlet of the feed pipe 138 points downwards, and one end of the feed pipe 138 is rotatably connected to the outlet of the feed bend 1310 via a rotary joint 139. The outlet of the feed bend 1310 points downwards and is located above the distribution hopper 111.

[0097] The transverse drive mechanism is mounted on the support base 131. The transverse drive mechanism includes a guide rail 132, a slider 133, a first cylinder 134, and a second cylinder 135. The slider 133 is slidably mounted on the guide rail 132. One end of the swing plate 136 is hinged to the slider 133. The feed bend 1310 passes through the swing plate 136. The first cylinder 134 is fixedly mounted on the slider 133. The second cylinder 135 is mounted on the support base 131. The first cylinder 134 and the second cylinder 135 are arranged along the moving direction of the slider 133. The output ends of the first cylinder 134 and the second cylinder 135 are connected by a snap-fit ​​component.

[0098] In this embodiment, the purpose of the two cylinders and the swing plate 136 working together is to drive the feed bend 1310 to swing slightly in the horizontal direction, so as to adjust the position of the feed bend 1310 above the distribution bucket 111, so as to achieve uniform feeding.

[0099] Specifically, the cylinder pushes the slider 133 to move along the length of the guide rail 132, and the swing plate 136 causes the feed bend 1310 to swing above the distribution tank 111, forming a fan-shaped feeding working area. More specifically, from the initial position to the final position, the outlet of the feed bend 1310 spans the three liquid storage chambers inside the distribution tank 111. This allows adjustment of the position of the outlet of the feed bend 1310 in the radial direction along the distribution tank 111. As the distribution tank 111 rotates, the feed bend 1310 swings back and forth, thereby evenly discharging the suspension into each liquid storage chamber.

[0100] In this embodiment, the purpose of providing two cylinders is to more conveniently control the swinging motion of the feed bend 1310. Specifically, when the extension rods of the two cylinders are not extended, the feed bend 1310 is in the initial position. When the first cylinder 134 extends to its maximum extent and the second cylinder 135 remains stationary, the feed bend 1310 is in the middle position in the radial direction of the distribution barrel 111. When both cylinders extend to their maximum extent, the feed bend 1310 is in the final position, that is, the position closest to the edge of the distribution barrel 111.

[0101] In some embodiments, the feed bend 1310 is provided with an interface for cleaning the pipeline, which can be connected to clean water to flush the pipeline when needed.

[0102] In some embodiments, since the feed bend 1310 extends a long distance and is a moving part, in order to ensure safety, a sling 1311 is designed on the feed bend 1310. One end of the sling 1311 is connected to the main steel structure to ensure safety and reduce the load on the rotary joint 139.

[0103] In some embodiments, the conveying pipe is divided into two sections, specifically a first conveying pipe 123 and a second conveying pipe 19. One end of the first conveying pipe 123 is connected to the discharge port on the side wall of the receiving hopper 12, and the other end is connected to the second conveying pipe 19 through a flange. The end of the second conveying pipe 19 away from the first conveying pipe 123 is connected to the inlet 704 of the L-shaped channel 706 on the top head 701.

[0104] In some embodiments, the filtration tube is divided into two sections, specifically a second tube body 21 and a first tube body 17. The second tube body 21 is connected to the drain hole 713 at the bottom of the chassis 703, and the bottom end of the second tube body 21 is connected to the first end of the first tube body 17 through a flange.

[0105] In summary, during actual operation, at least one of the operating modes of this vacuum water-driving system for solid material production is as follows:

[0106] The servo motor 15 starts running, driving the main shaft 8 to rotate slowly and continuously around its own axis. As the main shaft 8 rotates, the water distributor 7, the annular box 6, the material distribution mechanism 11, the conveying pipe, and the receiving hopper 12 also rotate slowly and continuously. At the same time, the electric valve on the connecting pipe 231 on the negative pressure tank 23 opens.

[0107] The suspension is fed into the receiving hopper 12 after passing through the feed pipe 138 and the feed bend 1310. As the distribution tank 111 rotates, the suspension enters multiple storage chambers. At the same time, the transverse drive mechanism drives the feed bend 1310 to swing slightly in the horizontal direction.

[0108] Under the combined action of vacuum negative pressure and the strainer 121, the waste liquid and the sucked air pass through the strainer 121 and flow into the conveying pipe, then into the L-shaped channel 706 of the top head 701, and then out from the bottom outlet 705 of the L-shaped channel 706 into the arc-shaped hole 707 of the disc 702, then flow from the arc-shaped hole 707 into the arc-shaped cavity 712 of the bottom plate 703, and finally flow from the drain hole 713 into the suction pipe, and then into the negative pressure tank 23 through the suction pipe.

[0109] When the roller 142 corresponding to one of the receiving hoppers 12 begins to enter the V-shaped channel, the receiving hopper 12 begins to rotate until the roller 142 corresponding to the receiving hopper 12 enters the lowest position of the V-shaped notch 202. At this time, the receiving hopper 12 has rotated 180° from top to bottom. At this time, the outlet 705 of the L-shaped channel 706 corresponding to the receiving hopper 12 is exactly aligned with the first purge hole 708 of the disc 702. The purge pump is immediately started, and compressed gas enters the purge pipe. After passing through the second purge hole 710 and the first purge hole 708 in sequence, the material enters the corresponding L-shaped channel 706 and finally enters the receiving hopper 12, which has been rotated 180°, from the conveying pipe, thereby cleaning the material stuck on the strain net 121. Subsequently, the roller 142 corresponding to the receiving hopper 12 begins to move upward along the V-shaped channel, and the receiving hopper 12 begins to reset. When the roller 142 just moves out of the V-shaped channel, the receiving hopper 12 rotates 180° and completes the reset.

[0110] Using a vacuum dewatering system for solid material production has at least the following advantages compared to traditional centrifugal dewatering technology;

[0111] First, the solid materials produced by this vacuum water-driving system have high integrity and will not cause mechanical damage to the solid materials. Moreover, the moisture content of the solid materials can be reduced by 25% compared with the centrifugal water-driving method.

[0112] Secondly, the entire process of feeding, distributing, pouring and water driving is fully automated, enabling continuous water driving operation without manual intervention, which greatly improves work efficiency.

[0113] Third, the designed compressed air purging can achieve complete automatic material discharge, avoiding the leakage of residual solid particles.

[0114] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
