Description

Technical Field

[0001] The utility model relates to the technical field of conveying devices, in particular to a silicon dioxide filter cake receiving and conveying device. Background Art

[0002] Silica is an important silicon-based inorganic functional powder material. Most of it is prepared by the traditional precipitation method, which uses sodium silicate solution and sulfuric acid as raw materials. The raw materials are passed into a reactor and the pH value is adjusted at a certain temperature to carry out a synthetic reaction to obtain silica precipitate. The slurry in the reactor is then passed through a pipe into a filter press for filtration and washing to remove sodium sulfate and impurities to obtain a filter cake. The workers then collect the filter cake and send it to a pulper for pulping, so that the filter cake is stirred and liquefied into a paste-like slurry. Finally, it is spray-dried to obtain a silica product. The existing filter cake receiving and conveying device can basically meet daily use needs, but there are still some shortcomings that need to be improved.

[0003] Patent document CN208342898U discloses a filter press filter cake dividing and conveying device, comprising a housing having an inverted trapezoidal cross-section, filter cake dividing knives arranged at intervals in the horizontal and vertical directions within the housing, a conveying auger within the bottom of the housing, the conveying auger comprising an auger shaft, the auger shaft being driven to rotate by a drive device, the auger shaft being provided with forward blades, the ends of the forward blades being coaxially provided with reverse blades, and a discharge port being provided at the intersection of the forward blades and the reverse blades. The filter press filter cake dividing and conveying device described in the utility model has a reasonable structure and can cut the filter cake into smaller pieces for transportation without manual crushing. It also avoids the difficulty and inconvenience of subsequent processing caused by the filter cake falling to the ground and crushing, thereby reducing workload and improving work efficiency.

[0004] As in the prior art of the above-mentioned patent, the filter cake is crushed and conveyed in the receiving and conveying device. Therefore, its conveying structure can usually be in a spiral form. When the spiral structure is a whole surface, its conveying capacity is strong, but it cannot have a good crushing capacity. When the spiral structure is multi-segmented, the crushing capacity can be enhanced, but due to the gaps between the multiple segments, the material is repeatedly stirred and scattered, and the conveying capacity is weakened. Therefore, a silica filter cake receiving and conveying device is urgently needed to solve the above problems. Utility Model Content

Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0032] See also Figure 1-9 The embodiment of the present invention provides a silica filter cake receiving and conveying device, which includes a receiving bin 1, a discharge port 2 is provided at the lower end of the receiving bin 1, and also includes: a roller body 3, which is symmetrically arranged in two in the receiving bin 1 and is rotatably connected to the receiving bin 1, and a plurality of spirally arranged blades 4 are provided on the outer wall thereof, and the blades 4 on the two roller bodies 3 are staggered; a plurality of baffles 5 are evenly arranged on the two opposite inner walls of the receiving bin 1 along the axial direction of the roller body 3, and a gap for the blades 4 to pass through is provided between two adjacent baffles 5; a driving assembly, which is used to drive the roller body 3 to rotate, and the two roller bodies 3 are arranged in opposite rotation directions.

[0033] Specifically, the upper end of the receiving bin 1 is open, and preferably, a container bucket can be provided to more conveniently receive the filter cake; arc-shaped shapes are provided on both sides of the inner bottom surface of the receiving bin 1, which match the area where the roller body 3 drives the blades 4 to rotate, avoiding the formation of conveying dead angles; the roller body 3 is cylindrical, and the axial direction is consistent with the length direction of the receiving bin 1; the two roller bodies 3 are spaced apart, and the spacing distance is consistent with the radial length of the blades 4 extending on the roller body 3; the blades 4 extend radially along the roller body 3; the blades 4 are independent sheets, and adjacent blades 4 have overlapping parts in the axial direction of the roller body 3 to ensure the conveying effect; the baffle 5 is arranged parallel to the radial direction of the roller body 3; the drive assembly can drive the roller body 3 to rotate in the forward and reverse directions, but the two roller bodies 3 always maintain opposite rotation directions. In actual use of this technical solution, the driving component drives the two rollers 3 to rotate, and the two rollers 3 drive the blades 4 to rotate to stir downward at the middle position of the two rollers 3. At this time, the filter cake received by the receiving bin 1 is driven by the blades 4 and crushed between the two rollers 3. Under the spiral motion of the adjacent blades 4, the crushed filter cake is transported in the receiving bin 1 toward the discharge port 2. In addition, when the crushed filter cake is driven upward again by the blades 4, it will be blocked by the baffle 5, and the blade 4 can pass through the gap between the two baffles 5 to maintain circulation, thereby ensuring that the filter cake is stably transported in the receiving bin 1 after being crushed, without repeated stirring or scattering.

[0034] Compared with the prior art, the silica filter cake receiving and conveying device proposed in the embodiment of the present invention is provided with spirally arranged blades 4. When the driving component drives the two rollers 3 to rotate in opposite directions, the filter cake received by the receiving bin 1 is driven by the blades 4 and crushed between the two rollers 3. Under the spiral motion of the adjacent blades 4, the crushed filter cake is conveyed in the receiving bin 1 toward the discharge port 2. In addition, when the crushed filter cake is driven upward again by the blades 4, it will be blocked by the baffle 5, and the blade 4 can maintain circulation through the gap between the two baffles 5, thereby ensuring that the filter cake is stably conveyed in the receiving bin 1 after being crushed, without being repeatedly stirred or scattered.

[0035] As the preferred technical solution of this embodiment, the driving component includes a gearbox 6 arranged at one end of the receiving bin 1, the output end of the gearbox 6 is connected to one of the rollers 3, and the input end of the gearbox 6 is installed with a motor 7. A functional bin 8 is provided at the other end of the receiving bin 1, and a linkage component is provided in the functional bin 8 for linking the two rollers 3 and keeping the two rollers 3 in opposite rotation directions. Specifically, the motor 7 drives one of the rollers 3 to rotate through the gearbox 6, and the driven roller 3 drives the other roller 3 to rotate in the opposite direction through the linkage component; the motor 7 can output in both directions under the control of the servo system, so that the rotation direction of the roller 3 can be switched forward and reverse.

[0036] As the preferred technical solution of this embodiment, the linkage assembly includes two mutually meshing transmission gears 9 that are rotatably arranged in the functional bin 8. One end of the rotating shaft of the roller body 3 extends into the functional bin 8 and is provided with a synchronous gear 10 that rotates synchronously. The synchronous gears 10 on the two roller bodies 3 are respectively meshed and connected with the two transmission gears 9. Specifically, the synchronous gear 10 on one roller body 3 is successively transmitted to the synchronous gear 10 on the other roller body 3 through the two transmission gears 9, thereby ensuring that the rotation directions of the two roller bodies 3 are opposite; the rotating shaft of the roller body 3 is connected to the synchronous gear 10 through a sliding keyway, so that the roller body 3 and the synchronous gear 10 maintain synchronous rotation while the rotating shaft of the roller body 3 can move axially relative to the synchronous gear 10.

[0037] In another embodiment of the present invention, a rotary rod 11 is rotatably provided on the side wall of the receiving bin 1, and the baffle 5 is fixedly provided on the rotary rod 11. The side wall of the receiving bin 1 is provided with a receiving groove 12 for the baffle 5 to move. Specifically, the baffle 5 is in the shape of a fan, and the center of the fan is the rotation center of the baffle 5 and is coaxially connected to the rotary rod 11; the baffle 5 can be driven by the rotary rod 11 to rotate to move into the receiving groove 12, thereby scraping off the material attached to the filter cake process below the baffle 5 and leaving it in the receiving bin 1; one end of the rotary rod 11 passes through the functional bin 8 and is provided with a crank.

[0038] As the preferred technical solution of this embodiment, a ring 13 is fixedly provided in the functional bin 8 and is sleeved on the outside of the rotating rod 11. A coil spring 14 is connected between the inner side of the ring 13 and the rotating rod 11. Specifically, the setting of the coil spring 14 limits the rotating axis of the rotating rod 11 by elastic force, and the rotating rod 11 drives the baffle 5 to fully extend into the receiving bin 1 without being affected by external force.

[0039] As the preferred technical solution of this embodiment, the roller body 3 can be axially movable, and an adjusting component for adjusting the axial position of the roller body 3 is provided in the functional bin 8. The adjusting component is automatically triggered when the rotary rod 11 drives the baffle 5 to rotate and completely retract into the receiving groove 12. Specifically, a groove for the roller body 3 to be movable is provided on the inner wall of the receiving bin 1 near the functional bin 8; when the baffle 5 is retracted into the receiving groove 12, part of the scraped material adheres to the inner wall of the receiving bin 1, and most of it is staggered with the rotation range of the blade 4. By setting the roller body 3 to be axially movable, the blade 4 can be adjusted. The rotation range of the blade 4 corresponds to the material adhered to the inner wall of the receiving bin 1 above, and then the rotation direction of the roller body 3 is switched, so that the blade 4 moves from top to bottom close to the inner wall of the receiving bin 1 to scrape the above-adhered material into the receiving bin 1; the adjustment component is automatically triggered when the rotary rod 11 drives the baffle 5 to rotate and is completely retracted into the receiving groove 12, which can match the timing when the baffle 5 is fully retracted and the material is adhered to the inner wall of the receiving bin 1, and then only the roller body 3 needs to be driven to rotate in the opposite direction to enable the blade 4 to clean the material adhered to the inner wall of the receiving bin 1.

[0040] As the preferred technical solution of this embodiment, the adjustment component includes an adjustment plate 15 movably arranged in the functional bin 8, and the roller body 3 extends into one end of the rotating shaft of the functional bin 8 and is rotatably connected to the adjustment plate 15 and moves synchronously with the adjustment plate 15. An elastic member 16 is connected between the adjustment plate 15 and the inner wall of the functional bin 8, and a stopper 17 is provided on the rotary rod 11. A through groove 18 matching the stopper 17 is provided on the adjustment plate 15. The stopper 17 corresponds to the through groove 18 when the rotary rod 11 drives the baffle 5 to rotate and completely retract into the storage groove 12. Specifically, the adjustment plate 15 moves along the axial direction of the roller body 3. , two spaced convex rings are provided at one end of the rotating shaft of the roller body 3 that penetrates deep into the functional warehouse 8, and the two convex rings are clamped on both sides of the adjustment plate 15 to synchronize the axial movement of the adjustment plate 15 and the roller body 3; the elastic member 16 can preferably be a spring, and the elastic member 16 is provided on the side of the adjustment plate 15 close to the inside of the receiving warehouse 1; the elastic member 16 keeps pushing the adjustment plate 15 in the direction away from the inside of the receiving warehouse 1; when the roller body 3 does not move axially toward the functional warehouse 8, the block 17 can block the side of the adjustment plate 15 away from the inside of the receiving warehouse 1, and at this time, the elastic member 16 is compressed and stores elastic potential energy.

[0041] As the preferred technical solution of this embodiment, a lever 19 is hinged on the outside of the functional bin 8, and a top block 20 that can slide through the functional bin 8 is fixedly provided on the adjustment plate 15. The lower end of the lever 19 is arranged corresponding to the protruding end of the top block 20. Specifically, when the roller body 3 moves axially toward the functional bin 8, the synchronously moving adjustment plate 15 drives the top block 20 to extend outward from the functional bin 8; the upper end of the lever 19 is pulled away from the functional bin 8, so that the lower end can push the top block 20 to move.

[0042] In actual use of the above embodiment, when the baffle 5 is to be stored, the crank at the end of the rotary rod 11 is first rotated, and the rotary rod 11 rotates to drive the baffle 5 to be stored in the storage groove 12, and the rotary rod 11 drives the coil spring 14 to twist and store elastic potential energy. At the same time, the rotary rod 11 drives the stopper 17 to rotate and approach the angular position of the through groove 18; when the baffle 5 is completely stored in the storage groove 12, the stopper 17 corresponds to the through groove 18, and the elastic potential energy of the elastic member 16 is released to push the adjustment plate 15, and the adjustment plate 15 drives the roller body 3 to move axially close to the functional bin 8 so that the position of the blade 4 is adjusted to the corresponding material attached to the inner wall of the receiving bin 1. At the same time, the adjustment plate 15 drives the top block 20 to extend outward from the functional bin 8, and the stopper 17 slides into the through groove 18 to limit the rotation of the rotary rod 11, so that the coil spring 14 stores elastic potential energy; Then, the roller body 3 is driven to rotate in the opposite direction through the driving component, so that the material attached to the inner wall of the receiving bin 1 can be cleaned. After the cleaning is completed, the lever 19 is pulled in the direction away from the outside of the functional bin 8, and the lower end of the lever 19 pushes the stopper 17, and the stopper 17 drives the adjusting plate 15 to move, and the adjusting plate 15 drives the roller body 3 to reset. When the adjusting plate 15 moves to the point where the stopper 17 is disengaged from the through slot 18, the elastic potential energy of the coil spring 14 is released, and the rotary rod 11 rotates. On the one hand, it drives the stopper 17 to rotate and stagger the through slot 18 to limit the adjusting plate 15 to the side away from the elastic member 16. On the other hand, the rotary rod 11 drives the baffle 5 to re-extend into the receiving bin 1, and the movement occurs after the roller body 3 is reset to avoid interference. After the stopper 17 limits the adjusting plate 15, the elastic potential energy of the elastic member 16 is maintained and the lever 19 can be released.

[0043] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
