Description

Technical Field

[0001] This invention relates to the field of chemical solid-liquid separation technology, and in particular to an automatic slag-removing solid-liquid separator. Background Technology

[0002] A solid-liquid separator is a separator based on the principle of centrifugal separation used to separate precipitable solids from liquids. In the production of chemical manufacturing or food processing, the treated mixed raw liquid will contain a large amount of precipitates and floating solids. These solid residues also contain liquid components. It is necessary to separate the mixture into solids and liquids by using a sedimentation device and a solid-liquid separator to extract the liquid and obtain high-purity chemical raw materials or food raw materials.

[0003] Existing solid-liquid separators have the following technical drawbacks: First, relying solely on the filter screen in the separator is insufficient to remove fine residues, and a significant amount of liquid components in the residues are lost, resulting in waste. Second, during centrifugal separation, residues may adhere to the mesh, causing blockages and reducing the efficiency of solid-liquid separation. Third, the discharge of filter residues is generally done manually, with low automation, which is time-consuming and labor-intensive. Furthermore, the inability to effectively remove residues can contaminate subsequent mixtures.

[0004] In summary, considering that existing facilities cannot meet the operational needs, we propose an automatic slag removal solid-liquid separator. Summary of the Invention

[0018] As a preferred embodiment of the automatic slag-removing solid-liquid separator of the present invention, the upper pressure plate and the sealing lower pressure plate move in opposite directions to squeeze the filter residue in the filtrate to form a filter residue agglomerate.

A slag receiving inner seat acting on the slag discharge pad is provided on the outer side of the base. A movable slag removal structure is provided inside the base and on the outside of the slag discharge pad.

[0019] As a preferred embodiment of the automatic slag-removing solid-liquid separator of the present invention, the movable slag removal structure includes sprockets, a drive shaft, a bearing housing, a constant-speed motor, a short shaft, and a drive chain. The sprockets are symmetrically distributed in four groups, with the last two groups connected by the drive shaft. One end of the drive shaft is fixed to the inner wall of the base via the bearing housing. The constant-speed motor is connected to one end of the drive shaft via a coupling and is horizontally fixed inside the base. The last two groups of sprockets are both fitted onto the short shaft, with one end of the short shaft fixed to the inner wall of the base via the bearing housing. Both the front and rear groups of sprockets are connected by the drive chain.

[0020] As a preferred embodiment of the automatic slag removal solid-liquid separator of the present invention, the movable slag removal structure further includes a pusher plate, a connecting block, and cleaning brushes. The pusher plate is located in the middle of two sets of transmission chains. Both ends of the pusher plate are fixed by the connecting block and the outer side of the transmission chain. When the pusher plate moves horizontally, it acts on the filter cake. Several sets of cleaning brushes are installed on the upper and lower end faces of the pusher plate. The cleaning brushes act on the lower end face of the upper pressure plate and the upper end face of the sealing lower pressure plate, respectively.

[0021] In a preferred embodiment of the automatic slag removal solid-liquid separator of the present invention, the liquid receiving container is fixed on the outer side of the base.

[0022] In a preferred embodiment of the automatic slag removal solid-liquid separator of the present invention, the base is provided with an annular connecting groove for bearing installation, and the number of the annular connecting grooves is 2 sets.

[0023] In a preferred embodiment of the automatic slag removal solid-liquid separator of the present invention, the rotating column rotates around the damping bearing.

[0024] In a preferred embodiment of the automatic slag removal solid-liquid separator of the present invention, the linear displacement roller moves linearly within the limiting and shock-absorbing sleeve.

[0025] This invention provides an automatic slag-removing solid-liquid separator, which has the following significant improvements and advantages compared with the prior art:

[0026] Start the servo motor to drive the crank to make circular motion. After rotating twice, the eccentric column traction drive disk rotates 180°. When the eccentric column moves, it contacts the two sets of strip thrust grooves in sequence, so that the rotating column rotates 180°, allowing the first and second top seats to alternate positions. The lifting cylinder and the second hydraulic cylinder work in turn.

[0027] The scraper is designed so that when the push rod motor is started, the push rod extends downward and drives the linear displacement roller to move downward. During the movement of the linear displacement roller, the telescopic plate, which is originally located in the planar support part, moves relative to the arc part and the inclined groove, causing the telescopic plate to extend outward, driving the connecting rod and scraper to move outward until the scraper contacts the filter screen and stops. On the one hand, multiple scrapers have synchronous telescopicity, which can be adapted to separation cylinders with different inner diameters, thus improving the applicability range. On the other hand, it can achieve the scraping effect on the filter screen, and the scraper will scrape off the residue in time.

[0028] The liquid is thrown outward from the filter screen due to centrifugal force and enters the collection tank with irregular movement, which is the first stage of separation. The liquid is then intercepted and filtered again through the fine filter screen to remove small residues, which is the second stage of separation. During the movement of the upper pressure plate and the sealing lower pressure plate, they merge at the position of the filter screen to squeeze the filter residue between them, which is the third stage of separation. The separation effect is significantly improved through multi-stage solid-liquid separation process.

[0029] Start the first hydraulic cylinder, and the first hydraulic rod extends upward, driving the lower sealing plate into the solid-liquid separation chamber. Since both the upper pressure plate and the lower sealing plate are in contact with the chamber wall, they scrape off the residue on the chamber wall during the movement. During the movement, the upper pressure plate and the lower sealing plate merge at the filter screen position, squeezing the filter residue between them. On the one hand, this further squeezes the liquid in the filter residue, improving the solid-liquid separation effect, and on the other hand, it effectively compresses and shapes the volume of the filter residue, finally forming filter residue clumps, which are convenient for subsequent collection and transportation.

[0030] The design incorporates a movable slag removal structure. A constant-speed motor drives the transmission shaft to rotate, which in turn causes two sets of transmission chains to rotate clockwise, moving a pusher plate. The pusher plate passes between the upper pressure plate and the lower sealing pressure plate, pushing the filter cake into the slag discharge pad. Simultaneously, cleaning brushes on the upper and lower surfaces of the pusher plate act on the lower surface of the upper pressure plate and the upper surface of the lower sealing pressure plate, cleaning any adhering residue. The pusher plate circulates multiple times along the transmission chain, cleaning the upper and lower sealing pressure plates repeatedly, improving cleaning efficiency and thoroughly transferring the filter cake to the slag discharge pad. This achieves automatic slag removal with a high degree of automation, saving time and labor. Attached Figure Description

[0045] 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. Example 1

[0046] like Figure 1-11 As shown, this embodiment provides an automatic slag-removing solid-liquid separator, including a base 1, which serves as a support and bearing. A centrifugal separator seat 2 is installed at the middle of the upper end of the base 1. A separation cylinder 10 is rotatably arranged inside the centrifugal separator seat 2. The upper and lower ends of the outer side of the separation cylinder 10 are connected to the inner wall of the centrifugal separator seat 2 through bearings 11. The separation cylinder 10 rotates around the bearings 11. An annular connecting groove 65 for the bearings 11 is opened inside the centrifugal separator seat 2. A large gear 12 is sleeved on the outer side of the separation cylinder 10.

[0047] Among them, a small gear 13 is meshed on one side of the large gear 12, and the small gear 13 is sleeved on the output shaft of the centrifugal motor 14. The centrifugal motor 14 is installed through the upper end face of the centrifugal separator 2, such as... Figure 2 As shown.

[0048] The separation cylinder 10 has a solid-liquid separation chamber 15 that runs through its interior. A filter screen 16, which is a coarse filter screen, is installed in the middle of the solid-liquid separation chamber 15. Figure 3 As shown.

[0049] Furthermore, a liquid collection inner groove 17 is annularly formed inside the centrifugal separator 2, corresponding to the position of the filter screen 16. The liquid collection inner groove 17 is angled to increase the liquid collection range and prevent leakage. A fine filter screen 18 is installed near the bottom of the liquid collection inner groove 17. Figure 4 As shown.

[0050] Furthermore, two sets of liquid outlets 60 are symmetrically arranged at the bottom of the liquid collection tank 17. A liquid guide pipe 61 is installed at each liquid outlet 60, extending outwards from the centrifugal separator 2. A liquid receiving container 62 is located below the liquid guide pipe 61 and is fixed to the outer side of the base 1. Figure 1 and 4 As shown.

[0051] The bottom of the solid-liquid separation chamber 15 is movably equipped with a sealing lower pressure plate 20. A sealing ring is provided around the outer perimeter of the sealing lower pressure plate 20 to prevent leakage. Figure 3 As shown.

[0052] Furthermore, a hydraulic rod 21 is welded to the middle position of the lower end face of the sealing pressure plate 20. The hydraulic rod 21 extends upward from the inside of the hydraulic cylinder 22, which is installed in the middle position inside the base 1. Figure 2 As shown.

[0053] Furthermore, a drive seat 31 is connected to the right side of the base 1 via two sets of connecting arms 30. A rotating groove 32 is provided inside the drive seat 31, and a rotating column 33 is rotatably mounted within the groove 32. The outer side of the rotating column 33 is connected to the rotating groove 32 via a damping bearing 34. The rotating column 33 rotates around the damping bearing 34, and the damping bearing 34 provides damping force, which can overcome the positional displacement caused by the inertia and vibration of the rotating column 33. Figure 5 and 6 As shown.

[0054] Specifically, a drive disk 35 is welded to the lower end of the rotating column 33. Four sets of strip-shaped thrust grooves 36 are symmetrically distributed inside the drive disk 35, and the four sets of strip-shaped thrust grooves 36 are connected by an annular channel. A servo motor 37 is vertically mounted eccentrically below the drive disk 35. The servo motor 37 is fixedly mounted at the bottom of the drive base 31. A crank 38 is mounted on the output shaft of the servo motor 37. An eccentric column 39 is welded to the upper edge of the crank 38. The eccentric column 39 extends upward into the strip-shaped thrust grooves 36 to drive the drive disk 35 to rotate. Figure 6 As shown.

[0055] Furthermore, two sets of symmetrical connecting plates 40 are welded to the portion of the rotating column 33 extending out of the drive seat 31. One set of connecting plates 40 is connected to a first top seat 41, and a lifting cylinder 42 is installed at the middle position of the upper end face of the first top seat 41. Figure 5 and 7 As shown.

[0056] Specifically, a lifting rod is installed downwardly inside the lifting cylinder 42, and a support column 43 is connected to the lower end of the lifting rod. The support column 43 extends downward beyond the lower end face of the first top seat 41, as shown below. Figure 7 As shown.

[0057] Among them, a push rod motor 44 is vertically installed at the upper part of the inside of the support column 43. A push rod 45 extends downward from the inside of the push rod motor 44, and a linear displacement roller 46 is welded to the lower end of the push rod 45. Figure 9 As shown.

[0058] Furthermore, a limiting and damping sleeve 47 is sleeved on the outer side of the linear displacement roller 46. The linear displacement roller 46 moves linearly within the limiting and damping sleeve 47. A limiting opening 64 is provided on the outer side of the limiting and damping sleeve 47, such as... Figure 8 As shown.

[0059] The linear displacement roller 46 has an inclined groove 48 on its surface that acts on the scraper 8. The inclined groove 48 is vertically inclined and has a limiting effect on the telescopic plate 81. A planar support part 49 is provided at the lower end of the inclined groove 48. When the telescopic plate 81 is in the position of the planar support part 49, it is in its initial state. Figure 9 As shown.

[0060] The outer surface of the support column 43 is provided with several sets of guide holes 63, which serve as guides and limiters. A scraper 8 extends outward from each set of guide holes 63, such as... Figure 7 As shown.

[0061] Specifically, the scraper 8 includes a telescopic plate 81, an arc-shaped portion 82, a spring 83, a connecting rod 84, and a scraper 85, such as... Figure 10 As shown.

[0062] In this embodiment, the lower end of the telescopic plate 81 is provided with an arc portion 82 to increase the sliding force during movement. The telescopic plate 81 moves on the inclined sliding groove 48 through the arc portion 82. The limiting port 64 allows the telescopic plate 81 to pass through, which plays a role in limiting and guiding. The inner side of the telescopic plate 81 and the guide hole 63 are connected and fixed by several sets of springs 83. When the springs 83 are compressed, they generate a reset force.

[0063] In this embodiment, a connecting rod 84 is welded to the middle of the telescopic plate 81. The connecting rod 84 extends outward through the guide hole 63. A scraper 85 is installed at the end of the connecting rod 84 away from the telescopic plate 81. The scraper 85 is inclined and attached to the filter screen 16 (an elastic rubber layer can be provided on the scraper 85 to increase the contact area with the filter screen 16). The scrapers 85 of several sets of scrapers 8 act on different annular areas on the filter screen 16. Each set of scrapers 8 scrapes obliquely and corresponds to multiple annular areas from top to bottom in sequence.

[0064] Furthermore, another set of connecting plates 40 is connected to a second top seat 50, and a second hydraulic cylinder 51 is vertically mounted at the middle position of the upper end face of the second top seat 50, such as... Figure 11 As shown.

[0065] Specifically, the second hydraulic rod 52 inside the second hydraulic cylinder 51 passes through the lower end face of the second top seat 50. An upper pressure plate 53 is welded to the lower end of the second hydraulic rod 52. The upper pressure plate 53 extends into the solid-liquid separation chamber 15 and fits against the inner wall of the solid-liquid separation chamber 15. A sealing ring is provided around the outer perimeter of the upper pressure plate 53 to prevent leakage. Figure 11 As shown.

[0066] The upper pressure plate 53 and the sealing lower pressure plate 20 move in opposite directions, squeezing the filter residue in the filtrate to form a filter residue agglomerate 66. The filter residue agglomerate 66 has a circular cross-section, the same as the pressure plate. A discharge pad 70 is provided on the outer side of the filter residue agglomerate 66, flush with the sealing lower pressure plate 20. The discharge pad 70 has a through hole in the middle for the sealing lower pressure plate 20 to move up and down. Figure 12 As shown.

[0067] Furthermore, the slag discharge pad 70 extends to the outer surface of the base 1, and the outer side of the base 1 is provided with a slag receiving inner seat 71 that acts on the slag discharge pad 70, such as... Figure 1 As shown.

[0068] In this embodiment, the mixture containing residue is poured into the solid-liquid separation chamber 15 of the separator 10 (the sealing lower pressure plate 20 acts as a liquid-blocking device). Then, the servo motor 37 is started, driving the crank 38 to make a circular motion. After rotating twice, the eccentric column 39 pulls the drive disk 35 to rotate 180° (the eccentric column 39 contacts the two sets of strip thrust grooves 36 in sequence during its movement). This causes the rotating column 33 to rotate 180°, allowing the first top seat 41 to move directly above the separator 10. At this time, the lifting cylinder 42 is started, and the lifting rod drives the support column 43 to move downwards into the solid-liquid separation chamber 15 until several sets of scrapers 8 are all in positions corresponding to the filter screen 16.

[0069] At this time, the push rod motor 44 is started, the push rod 45 extends downward and drives the linear displacement roller 46 to move downward. During the movement of the linear displacement roller 46, the telescopic plate 81, which was originally located in the planar support part 49, moves relative to the arc part 82 and the inclined groove 48, causing the telescopic plate 81 to extend outward, driving the connecting rod 84 and the scraper 85 to move outward until the scraper 85 contacts the filter screen 16 and then stops.

[0070] At this time, the centrifugal motor 14 is started, driving the small gear 13 to rotate at high speed, and through meshing, the large gear 12 rotates as well. The separation cylinder 10 moves at high speed, and the mixed liquid inside undergoes centrifugal motion at the height of the filter screen 16. The liquid is thrown outward from the filter screen 16 due to centrifugal force and enters the liquid collection tank 17 with irregular motion. It is collected in the liquid collection tank 17 and filtered again through the fine filter screen 18 to remove the small residues. The remaining liquid flows from the two sets of liquid outlets 60 into the liquid guide pipes 61 respectively, and after being discharged outward, it flows into the liquid receiving container 62.

[0071] The residue intercepted by the filter screen 16 remains in the solid-liquid separation chamber 15 (when the residue adheres to the filter screen 16, the scraper 85 will scrape off the residue in time due to the relative movement between the filter screen and the scraper 85). After the separation cylinder 10 finishes moving, the push rod 45 drives the linear displacement roller 46 to return upward. Under the reset force of the spring 83, several sets of scrapers 8 are retracted. Then, the lifting rod drives the support column 43 to return upward and leave the separation cylinder 10. At this time, the servo motor 37 is started again, and the rotating column 33 drives the second top seat 50 to rotate 180°, so that the second top seat 50 moves to the top of the separation cylinder 10 (exchanging positions with the first top seat 41). At this time, the second hydraulic cylinder 51 is started, and the second hydraulic rod 52 extends downward, driving the upper pressure plate 53 into the solid-liquid separation chamber 15. Inside the liquid separation chamber 15, hydraulic cylinder 22 is activated simultaneously, and hydraulic rod 21 extends upward, driving the lower sealing plate 20 into the solid-liquid separation chamber 15. Since both the upper pressure plate 53 and the lower sealing plate 20 are in contact with the chamber wall, they scrape off the residue on the chamber wall during the movement. During the movement, the upper pressure plate 53 and the lower sealing plate 20 merge at the filter screen 16, squeezing the filter residue between them. On the one hand, they further squeeze the liquid in the filter residue, and on the other hand, they effectively compress and shape the volume of the filter residue, finally forming a filter residue clump 66. Then, the upper pressure plate 53 and the lower sealing plate 20 hold the filter residue clump 66 and move it downward (the filter residue clump 66 passes through the solid-liquid separation chamber 15), and guide it from the slag discharge pad 70 into the slag receiving seat 71. Example 2

[0072] Based on Example 1, the filter cake 66 is typically cleaned manually during discharge, which is time-consuming and labor-intensive. Furthermore, the adhesive residue on the pressure plate cannot be effectively removed, contaminating the subsequent mixture. To address these issues, a movable slag removal structure 9 is installed inside the base 1 and outside the slag discharge pad 70. Figure 12-13 As shown.

[0073] Specifically, the movable slag removal structure 9 includes a sprocket 91, a drive shaft 92, a bearing housing 93, a constant-speed motor 94, a short shaft 95, and a drive chain 96, such as... Figure 13 As shown.

[0074] In this embodiment, there are four sets of sprockets 91 symmetrically distributed. The two sets of sprockets 91 at the rear are connected by a transmission shaft 92. One end of the transmission shaft 92 is fixed to the inner wall of the base 1 through a bearing seat 93, which serves to connect and fix the shaft. One end of the transmission shaft 92 is connected to a constant speed motor 94 through a coupling. The constant speed motor 94 is horizontally fixed inside the base 1.

[0075] In this embodiment, the two rear sets of sprockets 91 are both sleeved on the short shaft 95. One end of the short shaft 95 is fixed by the bearing seat 93 and the inner wall of the base 1. The front and rear sets of sprockets 91 are connected by the transmission chain 96.

[0076] Furthermore, the movable slag removal structure 9 also includes a pusher plate 97, a connecting block 98, and cleaning brushes 99, such as... Figure 13 As shown.

[0077] In this embodiment, the pusher plate 97 is located in the middle of the two sets of transmission chains 96. Both ends of the pusher plate 97 are fixed by the connecting block 98 and the outer side of the transmission chain 96. When the pusher plate 97 moves horizontally, it acts on the filter cake 66. Several sets of cleaning brushes 99 are installed on the upper and lower end faces of the pusher plate 97. The cleaning brushes 99 act on the lower end face of the upper pressure plate 53 and the upper end face of the sealing lower pressure plate 20, respectively.

[0078] Furthermore, in this embodiment, an intermediate receiving groove is provided between the slag discharge pad 70 and the slag receiving inner seat 71 to receive the filter slag clumps 66 falling from the slag discharge pad 70. The position of the intermediate receiving groove is designed not to interfere with the normal movement of the pusher plate 97.

[0079] In this embodiment, before using the movable slag removal structure 9, the second hydraulic rod 52 is moved slightly upward, causing the upper pressure plate 53 to move slightly upward, thus removing the pressure on the filter cake 66. Then, the uniform speed motor 94 is started, driving the transmission main shaft 92 to rotate. This, in conjunction with the four sets of sprockets 91, causes the two sets of transmission chains 96 to move clockwise. During the movement of the transmission chains 96, the pusher plate 97 is driven to move. The pusher plate 97 passes between the upper pressure plate 53 and the sealing lower pressure plate 20, pushing... The filter cake 66 moves, pushing it onto the slag discharge pad 70. At the same time, the cleaning brushes 99 on the upper and lower ends of the pusher plate 97 act on the lower end of the upper pressure plate 53 and the upper end of the sealing lower pressure plate 20, respectively, to clean the sticky residue on their ends. The pusher plate 97 moves cyclically multiple times along the trajectory of the transmission chain 96, cleaning the upper pressure plate 53 and the sealing lower pressure plate 20 multiple times, thereby completely transferring the filter cake 66 onto the slag discharge pad 70 and then pushing it into the intermediate collection tank for collection.
