Abstract
Description
Technical Field
[0001] This invention relates to the field of solid-liquid separation technology, specifically a solid sedimentation separation device for the outlet pipe of a centrifuge. Background Technology
[0002] In industry, horizontal screw centrifuges are frequently used to process solid-liquid mixtures. For example, horizontal screw centrifuges can effectively separate solid particles from water in coal slurry to obtain coal slurry with lower water content. However, the particle size, density, shape of the solid particles in the mixture, as well as the viscosity of the liquid, will affect the solid-liquid separation effect. When the solid particles are too small or the liquid viscosity is too high, the solid particles are easily discharged with the liquid in the outlet pipe. In addition, the instability of the feed flow rate or the change of the material concentration will also affect the separation effect of the centrifuge. When the feed flow rate is too large or the material concentration is too high, the residence time of the solid particles in the centrifuge is insufficient, resulting in the solid particles not being fully centrifuged and separated from the liquid.
[0003] To intercept solid particles and impurities flowing out of the liquid outlet pipe, the most common method is to fix a filter screen inside the outlet pipe. When the liquid passes through the filter screen, the solid particles are separated and retained on the filter screen. However, the number of solid particles retained on the filter screen gradually increases, which will affect the smooth flow of liquid in the outlet pipe. Therefore, users need to clean the solid particles and impurities on the filter screen frequently. Moreover, the cleaning of the filter screen and the filtration of solid particles and impurities cannot be carried out at the same time, which brings inconvenience to the filtration work of the outlet pipe. Summary of the Invention
[0004] The purpose of this invention is to provide a solid sedimentation separation device for the outlet pipe of a centrifuge, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A solid sedimentation separation device for the outlet pipe of a centrifuge includes:

[0010] Two traction mechanisms are fixed to the top of a rectangular pipe. Each traction mechanism includes a guide rail, a movable box that is slidably connected to the outside of the guide rail, a winding wheel that rotates on the outside of the movable box, and a traction rope that is fixed to the filter bag that is wound and fixed on the outside of the winding wheel.
[0011] There are two collection boxes, which are slidably connected to the top of the rectangular pipe and are used to collect solid particulate impurities poured out of the filter bag.
[0012] Furthermore, two rubber sheets are embedded and fixed inside the rectangular pipe, and two wedge-shaped blocks are fixed inside the rectangular pipe.
[0013] Furthermore, one end of the rectangular pipe is connected and fixedly connected to a connecting pipe 1 that is also fixedly connected to the liquid outlet pipe, and the other end of the rectangular pipe is connected and fixedly connected to a connecting pipe 2.
[0014] Furthermore, both ends of the shaft are fixed with gears that mesh with the rack, and the bottom of the filter bag is fixed with a counterweight column that is fixed with the traction rope.
[0015] Furthermore, the drive mechanism also includes:
[0016] A sleeve is rotatably connected to the top of the lead screw, and the sleeve is fixed to the top of the sedimentation separation tank.
[0017] Motor 1 is fixed inside the sedimentation separation box and is used to drive the lead screw to rotate in both directions.
[0018] Furthermore, one end of the receiving box is provided with an electric actuator two that is fixedly connected to the rectangular pipe, and the output end of the electric actuator two is fixedly connected to the receiving box.
[0019] Furthermore, the traction mechanism also includes:
[0020] Motor 2 is fixed inside the movable box and is used to drive the winding wheel to rotate in both directions;
[0021] Gear two is fixed to the outside of the winding wheel;
[0022] Rack 2 is fixed to one side of the guide rail, and rack 2 meshes with gear 2 for transmission.
[0023] Furthermore, electric actuators are fixed to the bottom of both ends of the rack two, and two tooth blocks are fixed to the output end of the electric actuators.
[0024] Preferably, the bottom of the rectangular pipe is provided with two sinking mechanisms, the sinking mechanisms including:
[0025] The pallet is placed on the bottom surface of the settling separator;
[0026] Two C-shaped shafts are inserted and fixed to the support plate;
[0027] Two return springs are fixed between the tray and the settling separation box.
[0028] Furthermore, a lifting plate is fixed between one end of the two I-shaped shafts, and the other end of the two I-shaped shafts abuts against a roller.
[0029] Compared with the prior art, the beneficial effects of the present invention are:
[0030] 1. By arranging rollers inside a rectangular pipe, with filter bags fixed to the outside of the rollers, water discharged from the outlet pipe of the horizontal screw centrifuge flows through the rectangular holes on the rollers into the filter bag. The filter bag easily intercepts and collects solid particles and impurities in the water that have not been centrifuged. Under the gravity of its internal counterweight column, the bottom side of the filter bag is always in the concave area of the rubber sheet in the rectangular pipe, so that the flow of water inside the rectangular pipe will not disturb the impurities that have settled to the bottom of the filter bag. The filter screen at the top of the filter bag can filter impurities in the water. The intercepted impurities fall to the bottom of the filter bag under their own gravity and the flushing action of the water flow. This allows the filter bag to filter and collect impurities in the water for a long time without being clogged by impurities, which helps to improve the filtration efficiency of solid particles and impurities in the water.
[0031] 2. The motor drives the lead screw to rotate, causing the drive block connected to the lead screw to move the shaft upward. The shaft then moves the roller and filter bag upward. When the gear at the end of the shaft moves to mesh with the rack, the gear drives the shaft to rotate counterclockwise outside the rack. This causes the roller on the shaft to rotate counterclockwise and roll up the filter bag. Under the gravity of the counterweight column, the filter bag can be tightly wrapped around the outside of the roller, which facilitates squeezing and drying the filter bag and the water. This separates the impurities in the filter bag from the water remaining on the filter bag, making it easier to clean the impurities inside the filter bag separately later.
[0032] 3. The gear at the end of the shaft rotates 90 degrees counterclockwise on the rack, causing the shaft to rotate 90 degrees with the roller. This causes the rectangular hole on the roller to rotate horizontally toward the rectangular pipe. The output end of the electric actuator extends, moving the receiving box below the rectangular hole of the roller. The motor drives the winding wheel and gear to rotate counterclockwise. The gear rotates counterclockwise on the rack, causing the moving box to move above the filter bag with the winding wheel. The winding wheel rotates counterclockwise to continuously wind up the traction rope. After the gear rolls to the leftmost position of the rack, the electric actuator on the rack moves away from the gear, allowing the gear to idle for a long time at the end of the rack. During the idle rotation of the motor and gear, the winding wheel continuously rotates to wind up the traction rope. This causes the traction rope to pull the bottom of the filter bag above the roller through the counterweight column, facilitating the falling of impurities inside the filter bag into the receiving box, thus achieving automatic cleaning of impurities inside the filter bag.
[0033] 4. After the bottom of the filter bag is pulled to the position above the roller by the traction rope, the motor can drive the winding wheel to rotate first to tighten the traction rope, and then rotate it slightly to release the traction rope. Then rotate it again to tighten the traction rope. Repeat this operation to make the counterweight column shake the filter bag, so that the impurities inside the filter bag can fall into the collection box quickly.
[0034] 5. The motor drives the lead screw to rotate in the opposite direction, causing the drive block to move the roller and filter bag on the shaft down into the rectangular pipe. When the gear on the shaft moves down, it will mesh with the rack and rotate clockwise, thus rotating the rectangular hole on the outside of the roller back to the horizontal direction for collecting water. The motor drives the winding wheel and the gear to rotate clockwise, so that the gear, which was used to pull the filter bag to the left end of the rack, returns to the right end of the rack. The winding wheel rotates clockwise to release the traction rope, meeting the distance requirements between the downward-moving filter bag and the winding wheel. After the gear moves to the rightmost position of the rack, the electric push rod on the right end of the rack can be disengaged with the gear, so that the gear is in a disengaged state at the right end of the rack. This allows the motor to drive the winding wheel to rotate counterclockwise to tighten the traction rope. The traction rope can then be used to pull the bottom of the filter bag to the recessed area of the rubber sheet in the rectangular pipe through the counterweight column, facilitating repeated collection of impurities by the filter bag.
[0035] 6. By installing two filter bags inside the rectangular pipe, when one filter bag contains a large amount of impurities, the traction mechanism above it, in conjunction with the drive mechanism, can be activated to automatically empty and clean the impurities inside the filter bag. At the same time, the other filter bag is moved into the rectangular pipe in advance by the drive mechanism to replace the filter bag being cleaned and perform the filtration operation. This allows the two filter bags to alternately filter impurities in a cyclical manner. The cleaning of the filter bags and the filtration of solid particulate impurities can be carried out simultaneously, further improving the filtration efficiency of the liquid discharged from the outlet pipe.

Detailed Implementation
[0047] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.
[0048] Example 1, please refer to Figure 1 - Figure 10 In this embodiment of the invention, a solid sedimentation separation device for a centrifuge outlet pipe includes a sedimentation separation box 200. A rectangular pipe 210 is fixedly installed inside the sedimentation separation box 200. One end of the rectangular pipe 210 is connected to the outlet pipe 110 of a horizontal screw centrifuge. Two support boxes 211 are fixed on both sides of the rectangular pipe 210. A filter assembly 300 is arranged between the two support boxes 211. The filter assembly 300 includes a shaft 310. A roller 320 is fixed to the outside of the shaft 310. A filter bag 330 is fixed to the outside of the roller 320. A drive mechanism 400 is provided at both ends of the shaft 310. The drive mechanism 400 includes a lead screw 410 and a rack 420. The outer side of the lead screw 410 is screwed to a drive block 411 that is rotatably connected to the shaft 310. The rack 420 and the shaft 310 are intermittently meshed for transmission. Two traction mechanisms 500 are provided on the inner top of the rectangular pipe 210. The traction mechanism 500 includes a guide rail 510. A movable box 520 is slidably connected to the outer side of the guide rail 510. A winding wheel 521 is rotatably connected to the outer side of the movable box 520. A traction rope that is fixed to the filter bag 330 is wound and fixed to the outer side of the winding wheel 521. Two collection boxes 600 are slidably connected to the top of the rectangular pipe 210.
[0049] Specifically, a filter bag 330 is arranged inside the rectangular pipe 210. Water entering the rectangular pipe 210 from the outlet pipe 110 is filtered through the filter bag 330. The filter bag 330 can intercept and hold a large amount of impurities, extending the filtration time. The drive mechanism 400 causes the roller 320 to move the filter bag 330 upward away from the rectangular pipe 210, and rotates the outer side of the take-up roller 320 to facilitate the separation of impurities from the water remaining on the filter bag 330 before cleaning the impurities inside the filter bag 330. The drive mechanism 400 then drives the roller 320 downward so that the opening of the filter bag 330 faces the receiving box 600. At the same time, the traction mechanism 500 moves to the filter bag. The filter bag 330 is lifted from above by a traction rope, so that the bottom of the filter bag 330 faces upward and the opening faces downward, which facilitates the automatic emptying and cleaning of impurities inside the filter bag 330. By installing two filter bags 330 simultaneously inside the rectangular pipe 210, each filter bag 330 is equipped with a drive mechanism 400 and a traction mechanism 500 to automatically clean the impurities inside the filter bag 330. This allows the other filter bag 330 to filter water while the other filter bag 330 is being cleaned, so that the cleaning of the filter bag 330 and the filtration of solid particulate impurities can be carried out simultaneously, which helps to improve the filtration efficiency of the liquid discharged from the outlet pipe 110.
[0050] like Figure 4 and Figure 6 As shown, in this embodiment, two rubber sheets 212 are embedded and fixed inside the rectangular pipe 210. The area of the rubber sheet 212 will move downward under the gravity of the counterweight column 331 of the filter bag 330, so that the bottom of the filter bag 330 can be below the water flow to collect impurities and prevent the water flow from washing away the impurities. At the same time, the rubber sheet 212 deforms downward and is concave so that the bottom of the filter bag 330 can collect a large amount of impurities.
[0051] In this embodiment, two wedge-shaped blocks 213 are fixed inside the rectangular pipe 210. The inclined surface of the wedge-shaped block 213 facilitates the guidance of water into the filter bag 330, and the arc-shaped surface on one side of the wedge-shaped block 213 facilitates the fitting and placement of the roller 320 inside the rectangular pipe 210.
[0052] like Figure 1 and Figure 2 As shown, in this embodiment, one end of the rectangular pipe 210 is connected to a connecting pipe 214 that is also connected to the outlet pipe 110. The connecting pipe 214 facilitates the transport of water from the outlet pipe 110 to the rectangular pipe 210 for solid sedimentation separation. A throttle valve is installed on the connecting pipe 214 to prevent a large flow of water from entering the rectangular pipe 210 and to prevent the water inside the rectangular pipe 210 from overflowing the top opening of the rectangular pipe 210. The other end of the rectangular pipe 210 is connected to a connecting pipe 215, which facilitates the discharge of water after solid sedimentation separation.
[0053] like Figure 2 As shown, in this embodiment, the sedimentation separation box 200 has two detachable door panels 216 on its outer side, and the receiving box 600 can be held by opening the door panels 216.
[0054] like Figure 6 As shown, in this embodiment, both ends of the shaft 310 are fixed with gears 311 that mesh with the rack 420. When the gears 311 move upward and mesh with the rack 420, they cause the upward-moving shaft 310 to rotate, thereby causing the shaft 310 to rotate and rotate the roller 320 to wind up the filter bag 330, or to adjust the orientation of the rectangular hole 321 on the roller 320. The rectangular hole 321 on the roller 320 is opened through and used for... Water is introduced into the filter bag 330. The bottom of the filter bag 330 is fixed with a counterweight column 331 that is fixed to the traction rope. The counterweight column 331 uses its own weight to press the bottom of the filter bag 330 into the recessed area of the rubber sheet 212 of the rectangular pipe 210. When the roller 320 rolls up the filter bag 330, the weight of the counterweight column 331 can make the filter bag 330 tightly rolled to the outside of the roller 320, thereby squeezing and spraying water onto the filter bag 330.
[0055] In this embodiment, both ends of the shaft 310 are configured as C-shapes. After the shaft 310, carrying the roller 320, moves down into the rectangular pipe 210, the rectangular pipe 210 near the end of the shaft 310 does not need a low-position opening to accommodate the end of the shaft 310. Furthermore, the C-shaped area of the shaft 310 is engaged inside the support box 211, so that the roller 320 is stably arranged inside the rectangular pipe 210. A damping pad of the prior art is sleeved between the drive block 411 and the shaft 310, so that when the shaft 310 moves upward and does not mesh with the rack 420, the shaft 310 itself will not rotate on the drive block 411.
[0056] like Figure 3 and Figure 6 As shown, in this embodiment, the drive mechanism 400 further includes a sleeve rotatably connected to the top of the lead screw 410. The sleeve is fixed to the top of the sedimentation separation box 200. A motor 430 for driving the lead screw 410 to rotate forward and backward is fixed inside the sedimentation separation box 200. The sleeve enables the lead screw 410 to rotate stably inside the sedimentation separation box 200. The motor 430 drives the lead screw 410 to rotate forward and backward, which can drive the drive block 411 to slide up and down along the lead screw 410. The two oppositely arranged lead screws 410 rotate simultaneously to realize the up and down adjustment of the position of the two drive blocks 411 with the shaft 310. The rack 420 is fixedly connected to the inner side of the sedimentation separation box 200, so that when the gear 311 moves to contact the rack 420, it causes the gear 311 to rotate.
[0057] like Figure 7 and Figure 8 As shown, in this embodiment, one end of the receiving box 600 is provided with an electric actuator 610 fixedly connected to the rectangular pipe 210. The output end of the electric actuator 610 is fixedly connected to the receiving box 600. When the roller 320 moves up to the point where the rectangular hole 321 faces down, the output end of the electric actuator 610 can be extended, so that the receiving box 600 moves below the roller 320 to receive impurities falling from the filter bag 330.
[0058] like Figure 7 and Figure 8 As shown, in this embodiment, a second motor is fixed inside the movable box 520. The output end of the second motor is fixedly connected to the winding wheel 521. A second gear 522 is fixed to the outside of the winding wheel 521. A second rack 530 is fixed to one side of the guide rail 510. The second rack 530 and the second gear 522 mesh and drive each other. The second motor drives the winding wheel 521 to rotate clockwise to release the traction rope. During the process of the roller 320 winding the filter bag 330, the winding wheel 521 can release the traction rope appropriately to meet the needs of the roller 320 to rotate and wind the filter bag 330. The second motor drives the winding wheel 521 to rotate counterclockwise to wind the traction rope. When it is necessary to turn the bottom of the filter bag 330 upward, the winding wheel 521 can wind the traction rope.
[0059] In this embodiment, the guide rail 510 is provided with a guide groove that slides and engages with the movable box 520. Both ends of the guide rail 510 are fixedly connected to the two support panels 217 on the top of the rectangular pipe 210, and the guide rail 510 is fixed together with the rack 530, thereby fixing the entire traction mechanism 500 inside the sedimentation separation box 200.
[0060] like Figure 8 and Figure 9 As shown, in this embodiment, electric actuators 540 are fixed to the bottom of both ends of rack 2 530. Two toothed blocks 541 are fixed to the output end of electric actuator 540. When gear 2 522 moves to the end of rack 2 530, in order to allow the winding wheel 521 to continue rotating to wind or release the traction rope, gear 2 522 meshes and idles on the upper part of rack 2 530. This allows the output end of electric actuator 540 to retract, causing the connecting block at the output end of electric actuator 540 to move downwards along with the two toothed blocks 541 on the top surface of the connecting block. Disengaging from gear 2 522, so that gear 2 522, which has moved to the end of rack 2 530, is no longer engaged with rack 2 530. If gear 2 522 needs to continue engaging with rack 2 530 to move to a new position, the output end of electric actuator 1 540 can be extended, so that the connecting block, along with the tooth block 541, re-engages with the outside of gear 2 522, allowing gear 2 522 to continue engaging and rolling on rack 2 530. Both ends of rack 2 530 are fixed with baffles to restrict gear 2 522 from disengaging from rack 2 530.
[0061] In Example 2, based on Example 1, in order to make the rubber sheet 212 area on the bottom surface of the rectangular pipe 210 sink when the roller 320 moves down into the rectangular pipe 210, so that the bottom of the filter bag 330 collects impurities in the sink area.
[0062] like Figure 5 As shown, in this embodiment, two sinking mechanisms 700 are provided at the bottom of the rectangular pipe 210. Each sinking mechanism 700 includes a support plate 710. Two C-shaped shafts 720 are inserted and fixed in the middle of the support plate 710. A lifting plate 721 is fixed between one end of the two C-shaped shafts 720. The other end of the two C-shaped shafts 720 abuts against the roller 320. Two return springs 730 are fixed between the support plate 710 and the settling separation box 200.
[0063] Specifically, when the roller 320 moves down into the rectangular pipe 210, it abuts against one end of the U-shaped shaft 720, causing it to move down along with the lifting plate 721. The rubber sheet 212 is fixed to the lifting plate 721, thus causing the lifting plate 721 to move down along with the rubber sheet 212. This allows the bottom of the filter bag 330 to be placed in the recessed area above the rubber sheet 212. When the roller 320 moves up away from the rectangular pipe 210, it no longer presses down on the U-shaped shaft 720, and the return spring... Under the compression force of the spring 730, the support plate 710 moves upward with the C-shaped shaft 720, and the C-shaped shaft 720 moves upward with the lifting plate 721, so that the rubber sheet 212 can move upward to a position flush with the inner bottom surface of the rectangular pipe 210. This prevents impurities in the water from accumulating in the recessed area of the rubber sheet 212 in the rectangular pipe 210 after the filter bag 330 is removed. This ensures that the rubber sheet 212 moves downward and recesses only when the roller 320 moves downward with the filter bag 330, leaving space for storing the filter bag 330.
[0064] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0065] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
