Description

Technical Field

[0001] The invention relates to the technical field of solid-liquid separation, in particular to a solid sedimentation separation device in a centrifuge liquid outlet pipe. Background Art

[0002] Horizontal screw centrifuges are often used in industry to process solid-liquid mixtures. For example, horizontal screw centrifuges can effectively separate solid particles from water in coal slurry water to obtain coal slurry with low water content. However, the particle size, density, shape of solid particles in the mixture and 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 easy to flow out with the liquid in the liquid 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, it is easy to cause the solid particles to have insufficient residence time in the centrifuge, resulting in the solid particles not being able to be fully centrifuged out of the liquid.

[0003] In order to intercept the solid particle impurities flowing out of the liquid outlet pipe, the most commonly used method is to fix a filter inside the liquid outlet pipe. When the liquid passes through the filter, the solid particles are separated and retained on the filter. However, the amount of solids retained on the filter gradually increases, which will affect the smooth liquid transportation of the liquid outlet pipe. In view of this, the user needs to frequently clean the solid particle impurities on the filter, and the cleaning of the filter and the filtering of the solid particle impurities by the filter cannot be carried out at the same time, which brings inconvenience to the filtering work of the liquid outlet pipe. Summary of the invention

[0004] The object of the present invention is to provide a centrifuge outlet pipe solid sedimentation separation device to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A centrifuge liquid outlet pipe solid sedimentation separation device, comprising:

[0007] A sedimentation separation box, wherein a rectangular pipe is fixedly passed through the interior of the sedimentation separation box, one end of the rectangular pipe is connected to the liquid outlet pipe on the horizontal screw centrifuge, and two support boxes are fixed on both sides of the rectangular pipe;

[0008] Two filter assemblies are arranged between two opposite support boxes, and the filter assemblies include a shaft, a roller is fixed to the outside of the shaft, and a filter bag is fixed to the outside of the roller;

[0010] There are two traction mechanisms, which are fixed on the top of the rectangular pipe. The traction mechanism includes a guide rail, a moving box is slidably connected to the outer side of the guide rail, a winding wheel is rotatably provided on the outer side of the moving box, and a traction rope fixed to the filter bag is wound and fixed on the outer side of the winding wheel;

[0011] There are two receiving boxes, which are slidably connected to the top of the rectangular pipe and are used to receive solid particle impurities dumped from the filter bag.

[0012] The invention further comprises: 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 fixed with a connecting pipe 1 connected and fixed with the liquid outlet pipe, and the other end of the rectangular pipe is connected and fixed with a connecting pipe 2.

[0014] Furthermore, both ends of the shaft rod are fixed with a gear 1 meshing with a rack 1 for transmission, and the inner bottom of the filter bag is fixed with a counterweight column fixed with a traction rope.

[0015] Further, the driving mechanism further comprises:

[0016] A sleeve is rotatably connected to the top of the screw rod, and the sleeve is fixed to the top of the sedimentation separation box;

[0017] Motor 1 is fixed inside the sedimentation separation box and is used to drive the screw to rotate forward and reverse.

[0018] Furthermore, one end of the receiving box is provided with an electric push rod 2 fixedly connected to the rectangular pipe, and an output end of the electric push rod 2 is fixedly connected to the receiving box.

[0019] Further, the traction mechanism further comprises:

[0020] Motor 2, fixed inside the moving box, is used to drive the winding wheel to rotate forward and reverse;

[0021] Gear 2, fixed on the outside of the winding wheel;

[0022] Rack 2 is fixed on one side of the guide rail, and the rack 2 is meshed with gear 2 for transmission.

[0023] Furthermore, an electric push rod 1 is fixed to the bottom of both ends of the second rack, and two tooth blocks are fixed to the output end of the electric push rod 1.

[0024] Preferably, two sinking mechanisms are provided at the bottom of the rectangular pipe, and the sinking mechanisms include:

[0025] A support plate is arranged on the bottom surface of the sedimentation separation box;

[0026] Two U-shaped shafts are inserted and fixed to the pallet;

[0027] Two reset springs are fixed between the pallet and the sedimentation separation tank.

[0028] Furthermore, a jacking plate is fixed between one ends of the two U-shaped shafts, and the other ends of the two U-shaped shafts are in contact with the rollers.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. By arranging rollers inside the rectangular pipe, a filter bag is fixed on the outer side of the rollers. The water discharged from the liquid outlet pipe of the horizontal screw centrifuge into the rectangular pipe flows through the rectangular holes on the rollers into the filter bag. The filter bag is convenient for intercepting and containing the solid particle impurities not centrifugally separated in the water. Under the gravity of the counterweight column inside it, the bottom side of the filter bag is always in the sunken area of the rubber sheet of the rectangular pipe, so that the flow of water inside the rectangular pipe will not disturb the impurities deposited on the inner bottom of the filter bag. The filter screen on the top of the filter bag can filter the impurities in the water, and the intercepted impurities will concentrate on the bottom of the filter bag under the action of their own gravity and the scouring of the water flow. Thus, the filter bag can filter and collect the impurities in the water for a long time and is not easily blocked by the impurities, which is beneficial to improving the filtering efficiency of the solid particle impurities in the water.

[0031] 2. By driving the screw rod to rotate by the first motor, the driving block screwed to the screw rod drives the shaft rod to move upward, and the shaft rod then drives the roller and the filter bag to move upward. When the first gear at the end of the shaft rod moves to mesh with the first rack and rotates, the first gear drives the shaft rod to rotate counterclockwise outside the first rack, so that the roller on the shaft rod rotates counterclockwise to wind up the filter bag. Under the gravity of the counterweight column, the filter bag can be tightly wound around the outer side of the roller, which is convenient for squeezing and draining the filter bag with water, separating the impurities in the filter bag from the water remaining on the filter bag, and facilitating the subsequent separate cleaning of the impurities inside the filter bag.

[0032] 3. The gear 1 at the end of the shaft rotates 90 degrees counterclockwise on the rack 1, so that the shaft rotates 90 degrees with the roller, so that the rectangular hole on the roller rotates horizontally toward the rectangular pipe, and the output end of the electric push rod 2 extends and moves the receiving box to the bottom of the roller rectangular hole. The motor 2 drives the winding wheel and the gear 2 to rotate counterclockwise. The gear 2 rotates counterclockwise on the rack 2 to make the moving box move to the top of the filter bag with the winding wheel. The winding wheel rotates counterclockwise to continuously reel in the traction rope. After the gear 2 rolls to the leftmost position of the rack 2, the electric push rod 1 on the rack 2 leaves the gear 2 with the tooth block, so that the gear 2 can idle for a long time at the end of the rack 2. During the idling of the motor 2 and the gear 2, the winding wheel continuously rotates and reels the traction rope, so that the traction rope pulls the bottom of the filter bag to the top of the roller through the counterweight column, so that the impurities inside the filter bag fall to the receiving box, thereby automatically cleaning the 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 second motor can drive the winding wheel to rotate and tighten the traction rope first, then slightly rotate it to release the traction rope, and then rotate it again to tighten the traction rope. Such a reciprocating operation can make the counterweight column bump with the filter bag, so that the impurities inside the filter bag can quickly fall into the receiving box.

[0034] 5. The motor 1 drives the screw rod to rotate in the opposite direction so that the driving block moves the roller and the filter bag on the shaft rod down to the inside of the rectangular pipe. When the gear on the shaft rod moves down, it will mesh with the rack 1 and rotate clockwise, so that the rectangular hole outside the roller rotates again to the horizontal direction of receiving water. The motor 2 drives the winding wheel and the gear 2 to rotate clockwise, so that the gear 2 moved to the left end of the rack 2 to pull the filter bag back to the right end of the rack 2. The winding wheel rotates clockwise to release the traction rope to meet the distance requirement between the downward-moving filter bag and the winding wheel. After the gear 2 moves to the rightmost position of the rack 2, the electric push rod 1 at the right end of the rack 2 can leave the gear 2 with the tooth block, so that the gear 2 is in a non-meshing state at the right end of the rack 2, thereby making the motor 2 drive the winding wheel to rotate counterclockwise to tighten the traction rope. The traction rope is convenient for pulling the bottom of the filter bag to the depression in the rubber sheet area of ​​the rectangular pipe through the counterweight column, so that the filter bag can repeatedly collect impurities.

[0035] 6. By arranging two filter bags inside the rectangular pipe, when a large amount of impurities are contained in one filter bag, the traction mechanism above it can be activated to cooperate with the driving mechanism to automatically dump and clean the impurities inside the filter bag. At the same time, the other filter bag is moved to the inside of the rectangular pipe through the driving mechanism in advance to replace the filter bag being cleaned to perform the filtering operation, so that the two filter bags can filter impurities alternately and cyclically. The cleaning of the filter bag and the filtering of solid particle impurities by the filter bag can be carried out simultaneously, further improving the efficiency of the liquid filtration of the liquid outlet pipe.

Detailed implementation manners

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] For example, see Figure 1 - Fig.10 In an embodiment of the present invention, a centrifuge outlet pipe solid sedimentation separation device includes a sedimentation separation box 200, a rectangular pipe 210 is fixedly passed through the sedimentation separation box 200, one end of the rectangular pipe 210 is connected to the outlet pipe 110 on the horizontal screw centrifuge, two support boxes 211 are fixed on both sides of the rectangular pipe 210, and 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 on the outer side of the shaft 310, a filter bag 330 is fixed on the outer side of the roller 320, and a driving mechanism 400 is arranged at both ends of the shaft 310. The driving mechanism 400 includes a screw rod 410 and a rack 420. The outer side of the screw rod 410 is screwed and connected with a driving block 411 rotatably connected to the shaft rod 310. The rack 420 intermittently meshes with the shaft rod 310 for transmission. Two traction mechanisms 500 are arranged on the inner top of the rectangular pipe 210. The traction mechanism 500 includes a guide rail 510. A moving box 520 is slidably connected to the outer side of the guide rail 510. A winding wheel 521 is rotatably provided on the outer side of the moving box 520. A traction rope fixed to the filter bag 330 is wound and fixed on the outer side of the winding wheel 521. Two receiving boxes 600 are slidably connected to the top of the rectangular pipe 210.

[0049] Specifically, by arranging the filter bag 330 inside the rectangular pipe 210, the water entering the rectangular pipe 210 from the liquid outlet pipe 110 is filtered through the filter bag 330, and the filter bag 330 can intercept and contain a large amount of impurities, thereby extending the time for filtering impurities. The roller 320 is driven by the driving mechanism 400 to move up with the filter bag 330 and leave the rectangular pipe 210, and the outer side of the winding roller 320 is rotated to facilitate cleaning of the impurities inside the filter bag 330. The impurities are separated from the water remaining on the filter bag 330, and the roller 320 is driven by the driving mechanism 400 to move down again so that the bag opening of the filter bag 330 faces the receiving box 600, and at the same time, the traction mechanism 500 moves to the filter bag The filter bag 330 is lifted up by a traction rope above 330, so that the bottom of the filter bag 330 faces upward and the bag opening faces downward, so that the impurities inside the filter bag 330 can be automatically dumped and cleaned. By installing two filter bags 330 at the same time inside the rectangular pipe 210, each filter bag 330 is equipped with a driving mechanism 400 and a traction mechanism 500 to automatically clean the impurities inside the filter bag 330, so that during the process of cleaning one filter bag 330, the other filter bag 330 can replace the filter bag 330 being cleaned to filter water, so that the cleaning of the filter bag 330 and the filtering of solid particle impurities by the filter bag 330 can be carried out simultaneously, which is beneficial to improving the efficiency of filtering the liquid discharged from the liquid 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 rubber sheet 212 area 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 located below the water flow to receive impurities and prevent the water flow from washing away the impurities. At the same time, the rubber sheet 212 is deformed and concave downward so that a large amount of impurities can be collected at the bottom of the filter bag 330.

[0051] In this embodiment, two wedge blocks 213 are fixed inside the rectangular pipe 210. The inclined surface of the wedge block 213 facilitates guiding water into the filter bag 330, and the curved surface on one side of the wedge block 213 facilitates fitting the roller 320 into the rectangular pipe 210.

[0052] like Figure 1 and Figure 2 As shown, in the present embodiment, one end of the rectangular pipe 210 is connected and fixed with a connecting pipe 214 connected and fixed with the liquid outlet pipe 110. The connecting pipe 214 facilitates the transportation of water from the liquid outlet pipe 110 to the rectangular pipe 210 for solid sedimentation and 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 flooding the top opening of the rectangular pipe 210. The other end of the rectangular pipe 210 is connected and fixed with a connecting pipe 215. The connecting pipe 215 facilitates the discharge of water after solid sedimentation and separation.

[0053] As Figure 2 shown, in this embodiment, two door panels 216 are detachably fixed to the outside of the sedimentation separation box 200, and the door panels 216 can be opened to receive the receiving box 600.

[0054] As Figure 6 shown, in this embodiment, a first gear 311 meshing with the first rack 420 is fixed to both ends of the shaft rod 310. When the first gear 311 moves upward to mesh with the first rack 420 for transmission, the upward moving shaft rod 310 will rotate on its own axis, and then the shaft rod 310 will drive the roller 320 to rotate and wind up the filter mesh bag 330, or adjust the orientation of the rectangular hole 321 on the roller 320. Among them, the rectangular hole 321 on the roller 320 is opened through for guiding water into the filter mesh bag 330. A counterweight column 331 fixed to the traction rope is fixed to the inner bottom of the filter mesh bag 330. The counterweight column 331 can press the bottom of the filter mesh bag 330 against the concave area of the rubber sheet 212 of the rectangular pipe 210 by its own gravity. When the roller 320 winds up the filter mesh bag 330, the gravity of the counterweight column 331 can prompt the filter mesh bag 330 to be tightly wound to the outside of the roller 320 to realize squeezing and watering the filter mesh bag 330.

[0055] In this embodiment, both ends of the shaft rod 310 are set in a U-shape. After the shaft rod 310 drives the roller 320 to move downward into the rectangular pipe 210, the position of the rectangular pipe 210 near the end of the shaft rod 310 does not need to be opened at a low position to accommodate the end of the shaft rod 310, and the U-shaped area of the shaft rod 310 is clamped inside the support box 211, so that the roller 320 is stably arranged inside the rectangular pipe 210. Among them, a damping gasket of the prior art is sleeved between the driving block 411 and the shaft rod 310, so that when the shaft rod 310 moves upward and is not in meshing contact with the first rack 420, the shaft rod 310 itself will not rotate on the driving block 411.

[0056] As Figure 3 and Figure 6 shown, in this embodiment, the driving mechanism 400 further includes a sleeve rotatably connected to the top of the lead screw 410, and the sleeve is fixed to the inner top of the sedimentation separation box 200. A first 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 first motor 430 driving the lead screw 410 to rotate forward and backward can drive the driving block 411 to slide up and down along the lead screw 410. When the two relatively arranged lead screws 410 rotate simultaneously, the two driving blocks 411 drive the shaft rod 310 to adjust the position up and down. The first rack 420 is fixedly connected to the inner side of the sedimentation separation box 200, so that when the first gear 311 moves to contact the first rack 420, it will cause the first gear 311 to rotate.

[0057] As Figure 7 and Figure 8 As shown, in this embodiment, one end of the receiving box 600 is arranged with an electric push rod 610 fixedly connected to the rectangular pipe 210, and the output end of the electric push rod 610 is fixedly connected to the receiving box 600. When the roller 320 moves up to the rectangular hole 321 facing downward, the output end of the electric push rod 610 can be extended, so that the receiving box 600 moves to the bottom of the roller 320 to receive impurities falling from the filter bag 330.

[0058] like Figure 7 and Figure 8 As shown, in the present embodiment, a second motor is fixed inside the movable box 520, and an output end of the second motor is fixedly connected to a winding wheel 521, a second gear 522 is fixed to an outer side of the winding wheel 521, a second rack 530 is fixed to one side of the guide rail 510, and the second rack 530 is meshed with the second gear 522 for transmission. The second motor drives the winding wheel 521 to rotate clockwise to release the traction rope. During the process of the roller 320 rolling up the filter bag 330, the winding wheel 521 can release the traction rope appropriately to meet the requirement of the roller 320 rotating and rolling up the filter bag 330. The second motor drives the winding wheel 521 to rotate counterclockwise to roll up the traction rope. When the filter bag 330 needs to be turned bottom up, the winding wheel 521 can roll up the traction rope.

[0059] In this embodiment, a guide groove is provided on the guide rail 510 for sliding engagement with the moving box 520, both ends of the guide rail 510 are fixedly connected to the two support panels 217 at the top of the rectangular pipe 210, and the guide rail 510 is fixed together with the rack 2 530, thereby fixing the entire traction mechanism 500 inside the sedimentation separation box 200.

[0060] like Figure 8 and Fig. 9 As shown, in this embodiment, electric push rod 1 540 is fixed at the bottom of both ends of rack 2 530, and two tooth blocks 541 are fixed to the output end of electric push rod 1 540. When gear 2 522 moves to the end of rack 2 530, in order to realize that the winding wheel 521 continues to rotate to reel in or release the traction rope, gear 2 522 engages and idles on the upper part of rack 2 530, so that the output end of electric push rod 1 540 can be contracted, so that the connecting block at the output end of electric push rod 1 540 moves downward with the two tooth blocks 541 on the top surface of the connecting block. When the gear 522 leaves the gear 2 522, the gear 2 522 moved to the end of the rack 2 530 is no longer meshed with the rack 2 530. When the gear 2 522 needs to continue to mesh with the rack 2 530 and move to a different position, the output end of the electric push rod 1 540 can be extended to allow the connecting block to re-engage with the tooth block 541 to the outside of the gear 2 522, so that the gear 2 522 can continue to mesh and roll on the rack 2 530. Baffles are fixed at both ends of the rack 2 530 to limit the gear 2 522 from leaving the rack 2 530.

[0061] Embodiment 2. On the basis of Embodiment 1, in order to achieve the depression of the rubber sheet 212 area on the bottom surface of the rectangular pipe 210 when the roller 320 moves down into the rectangular pipe 210, so that the bottom of the filter bag 330 collects impurities in the depressed area.

[0062] As Figure 5 shown, in this embodiment, two sinking mechanisms 700 are provided at the bottom of the rectangular pipe 210. The sinking mechanism 700 includes a support plate 710. Two U-shaped shafts 720 are inserted and fixed in the middle of the support plate 710. A jacking plate 721 is fixed between one ends of the two U-shaped shafts 720. The other ends of the two U-shaped shafts 720 are in contact with the roller 320. Two return springs 730 are fixed between the support plate 710 and the sedimentation separation tank 200.

[0063] Specifically, when the roller 320 moves down into the rectangular pipe 210, the roller 320 abuts against one end of the U-shaped shaft 720 to drive the jacking plate 721 to move down. The rubber sheet 212 is fixed to the jacking plate 721. Thus, the jacking plate 721 drives the rubber sheet 212 to move down, so that the bottom of the filter bag 330 can be placed in the depressed area above the rubber sheet 212. When the roller 320 moves up and leaves the rectangular pipe 210, the roller 320 no longer presses down on the U-shaped shaft 720. Under the action of the compression elastic force of the return spring 730, the support plate 710 drives the U-shaped shaft 720 to move up, and the U-shaped shaft 720 drives the jacking plate 721 to move up, so that the rubber sheet 212 can move up to a position flush with the inner bottom surface of the rectangular pipe 210, preventing water impurities from accumulating in the depressed area of the rectangular pipe 210 where the rubber sheet 212 is located after the filter bag 330 is removed. It is realized that the rubber sheet 212 moves down and depresses only when the roller 320 drives the filter bag 330 to move down, leaving a space for storing the filter bag 330.
