Description

Technical Field

[0001] This invention relates to the field of batching equipment technology, and more specifically, to a batching equipment for salt chemical industry. Background Technology

[0002] Salt chemical batching is a crucial step in chemical production, and the uniformity of its batching directly affects the purity, reaction efficiency, and quality stability of subsequent products. Currently, commonly used batching equipment in the salt chemical industry mainly includes a mixing drum, a drive motor, a mixing shaft, and a fixedly installed mixing paddle, which achieves material mixing through the rotation of the mixing paddle.

[0003] Existing equipment typically uses fixed-angle, fixed-position agitators, such as anchor, paddle, or spiral types, which can only achieve circumferential mixing in one direction. This results in significant axial and radial dead zones within the mixing drum, ultimately leading to insufficient uniformity of the batching, affecting the stability of subsequent chemical reactions, or requiring longer mixing times to improve the mixing effect and increasing the batching time. Furthermore, the mixing, unloading, and cleaning functions of existing equipment are mostly independently set up, requiring manual switching or additional devices. For example, after mixing, the machine must be stopped to open the unloading port, relying on the material's own weight or auxiliary pushing devices for unloading, which easily leaves residue. Cleaning requires disassembling the mixing components or manually entering the drum to rinse / scrape away residue, which is not only cumbersome but also poses safety hazards. Therefore, we propose a salt chemical batching equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a salt chemical batching equipment to solve the technical problems of poor batching effect and difficulty in switching between batching, unloading and cleaning modes in the prior art.

[0005] This invention provides a salt chemical batching equipment, including a mixing drum on which a mixing component is installed;

[0006] The lifting assembly includes a hydraulic cylinder mounted on a mixing drum. A support plate is mounted on the output end of the hydraulic cylinder. The support plate is slidably connected to the mixing drum. A sleeve is rotatably connected to the support plate. The sleeve is slidably connected to the output end of the mixing assembly. Two sets of guide rods are mounted on the sleeve. An adjusting rod is mounted on the guide rod.

[0007] The regulating component includes a support tube installed at the output end of the stirring component, an regulating tube rotatably installed inside the support tube, a guide rod inserted into the regulating tube, the outer diameter of the guide rod matching the inner diameter of the regulating tube, several regulating plates installed on the regulating tube, the regulating plates passing through the regulating groove on the support tube, a reversing groove opened on the regulating tube, and a guide groove communicating with the reversing groove opened on the regulating tube at the far end, and the regulating rod sliding in the reversing groove and the guide groove;

[0008] The output end of the hydraulic cylinder drives the adjusting rod to move, which forces the adjusting tube to rotate the adjusting plate, thereby adjusting the different working ranges of the adjusting plate in the material feeding and cleaning modes.

[0009] As a further description of the above technical solution, the stirring assembly includes a geared motor mounted on the stirring drum, and a support shaft rotatably connected to the stirring drum is mounted on the output end of the geared motor. Several spiral plates are mounted on the support shaft.

[0010] As a further description of the above technical solution, the radial distances between the two support tubes and the support shaft are not equal, and the length of the adjustment plate on the proximal adjustment assembly is greater than the length of the adjustment plate on the distal adjustment assembly.

[0011] As a further description of the above technical solution, the guide groove is parallel to the axis of the support shaft, and the circumferential deflection angle of the reversing groove on the far end side is greater than the circumferential deflection angle of the reversing groove on the near end side.

[0012] As a further description of the above technical solution, it also includes an unloading assembly, which includes a connecting block that slides on a support shaft, two sets of support rods are mounted on the connecting block, and a scraper is mounted below the support rods.

[0013] As a further description of the above technical solution, a connecting sleeve is rotatably installed inside the connecting block, and a discharge pipe is slidably connected inside the connecting sleeve. The discharge pipe is connected to the unloading pipe of the mixing drum. A discharge hole is opened on the discharge pipe, and the discharge pipe and the unloading pipe are slidably connected. The output end of the telescopic cylinder installed on the mixing drum is fixedly connected to the discharge pipe.

[0014] As a further description of the above technical solution, the adjustment plates of the two sets of adjustment components are staggered along the axial direction of the support shaft.

[0015] As a further description of the above technical solution, the radial distance between the centerline of several scrapers and the axis of the support shaft is not equal.

[0016] As a further description of the above technical solution, the height of the discharge hole is less than the height of the connecting sleeve.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0018] 1. In this invention, the adjusting plates of the two sets of adjusting components are staggered along the support shaft and have unequal radial distances. With adjusting plates of different lengths, they respectively contact different radius areas of the inner wall of the mixing drum, which can cover the entire axial / radial area of ​​the mixing drum from the center to the inner wall, eliminating the dead zones of traditional mixing. The adjusting plates are driven by the lifting component and swing around the axis of the adjusting tube in the material feeding mode. Combined with the circumferential rotation of the spiral plate, a radial disturbance flow field is formed. The centerline of the bottom scraper is unequal to the radial distance of the support shaft, covering different radius areas at the bottom, avoiding the deposition of materials at the bottom, and realizing the mixing of materials in the mixing drum without dead zones.

[0019] 2. This invention integrates mixing, unloading, and cleaning functions into one unit. A telescopic cylinder drives the discharge pipe upwards, sealing the discharge hole and disengaging the scraper from the bottom. A hydraulic cylinder drives the adjusting rod upwards, causing the adjusting plate to enter a feeding mode, where the spiral plate, adjusting plate, and scraper work together to mix. When the telescopic cylinder drives the discharge pipe downwards, the discharge hole connects with the mixing drum, and the material is discharged through the discharge pipe. Simultaneously, the scraper moves downwards to contact the bottom, assisting in pushing away residual material and avoiding dead zones during unloading. The hydraulic cylinder drives the adjusting rod downwards, causing the adjusting plate to rotate and contact the inner wall of the mixing drum. The telescopic cylinder drives the scraper downwards to contact the bottom, and the rotation of the support shaft causes the adjusting plate and scraper to move synchronously, removing material adhering to the drum wall and bottom in one go. This prevents residual material from solidifying and caking, thus avoiding contamination during subsequent batching and ensuring the purity of the salt chemical batching.

[0020] 3. The adjusting plate of this invention has a pressure relief hole, which can reduce the positive pressure of the material on the plate surface when rotating; in the feeding mode, the angle between the adjusting plate and the tangent of the support shaft is <45°, and it is located on the opposite side of the rotation direction of the adjusting tube, which reduces the impact resistance of the material; the scraper is located on the opposite side of the rotation direction of the support rod. When stirring, the scraper moves up and does not contact the bottom. The adjusting plate maintains a safe distance from the inner wall, avoiding plate surface deformation or inner wall wear caused by long-term contact, and reducing frictional resistance.

[0033] 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.

[0034] Reference Figures 1 to 11This embodiment discloses a salt chemical batching equipment, including a mixing drum 1. A fixed pipe 11 is fixedly installed on the top of the mixing drum 1, and a discharge pipe 12 is connected to the bottom of the mixing drum 1. A mixing assembly 2 is installed on the mixing drum 1. The mixing assembly 2 includes a reduction motor 21 fixedly installed on the fixed pipe 11. A support shaft 22 rotatably connected to the fixed pipe 11 is fixedly installed at the output end of the reduction motor 21. The support shaft 22 is coaxial with the mixing drum 1. A plurality of spiral plates 23 are fixedly installed on the support shaft 22. The plurality of spiral plates 23 are arranged in a circular array around the axis of the support shaft 22 and are located inside the mixing drum 1. The rotation of the spiral plates 23 can drive the material in the mixing drum 1 to mix, thereby realizing batching.

[0035] Reference Figures 1 to 4 A lifting assembly 3 is installed on the fixed pipe 11. The lifting assembly 3 includes a hydraulic cylinder 31 fixedly installed on the fixed pipe 11. A support plate 32 is fixedly installed at the output end of the hydraulic cylinder 31. The support plate 32 is slidably connected to the fixed pipe 11. A sleeve 33 is rotatably connected to the support plate 32. Figure 4 As shown, the sleeve 33 has a toothed groove, and the sleeve 33 is slidably connected to the support shaft 22 through the toothed groove. The sliding direction is the axial direction of the support shaft 22. The sleeve 33 is inserted into the stirring drum 1. Two sets of guide rods 34 are fixedly installed at the bottom of the sleeve 33, and an adjusting rod 35 is fixedly installed on the guide rods 34.

[0036] Reference Figure 2 , Figure 3 , Figures 5 to 8Two sets of adjusting components 4 are installed on the support shaft 22. Each adjusting component 4 includes a support tube 41 fixedly installed on the support shaft 22. The radial distances between the support tubes 41 and the support shaft 22 are unequal. An adjusting tube 42 is rotatably installed inside the support tube 41, and the inner diameter of the support tube 41 matches the outer diameter of the adjusting tube 42 to prevent the mixture from entering the gap between them. A guide rod 34 is inserted into the adjusting tube 42, and the outer diameter of the guide rod 34 matches the inner diameter of the adjusting tube 42. The guide rod 34 can rotate around the axis or slide up and down axially within the adjusting tube 42. Several adjusting plates 43 are fixedly installed on the adjusting tube 42. Each adjusting plate 43 has a pressure relief hole 44 to reduce rotational resistance when it rotates circumferentially with the support shaft 22. Several adjusting grooves 45 are provided on the support tube 41, and the adjusting plates 43 pass through the adjusting grooves 45. The two sets of adjusting components 4... The adjusting plates 43 are staggered along the axial direction of the support shaft 22. Therefore, the adjusting plates 43 on the two sets of adjusting components 4 can achieve stirring coverage in the axial direction of the support shaft 22, thereby reducing the axial stirring dead angle of the mixing drum 1 and improving the mixing effect of the ingredients. The adjusting pipe 42 is provided with a reversing groove 46. The far end (far from the support shaft 22) of the adjusting pipe 42 is provided with a guide groove 47 that communicates with the reversing groove 46. The guide groove 47 is parallel to the axis of the support shaft 22. The adjusting rod 35 slides in the reversing groove 46 and the guide groove 47. The length of the adjusting plate 43 on the near end (closer to the support shaft 22) of the adjusting component 4 is greater than the length of the adjusting plate 43 on the far end of the adjusting component 4. The circumferential deflection angle of the reversing groove 46 corresponding to the longer adjusting plate 43 is greater than the circumferential deflection angle of the reversing groove 46 corresponding to the shorter adjusting plate 43. Therefore, the longer adjusting plate 43 has a larger swing range.

[0037] Reference Figures 6 to 8 When the near-end adjusting rod 35 is located at the bottom of the reversing groove 46 of the adjusting tube 42 and the far-end adjusting rod 35 is located at the bottom of the guide groove 47 of the adjusting tube 42, the longer adjusting plate 43 is in position a and the shorter adjusting plate 43 is in position b. The ends of both sets of adjusting plates 43 are in contact with the inner wall of the mixing drum 1. At this time, it is the cleaning mode. The adjusting plate 43 can be rotated by the support shaft 22 to clean the inner wall of the mixing drum 1, thereby preventing the ingredients from sticking to the inner wall of the mixing drum 1.

[0038] When the distal adjusting rod 35 moves up to the connection between the guide groove 47 and the reversing groove 46, the proximal adjusting rod 35 slides in the reversing groove 46, forcing the adjusting tube 42 to drive the longer adjusting plate 43 to rotate to position c. At this time, the shorter adjusting plate 43 is still in position b.

[0039] As the two adjusting rods 35 continue to move upward, the two adjusting tubes 42 can drive the corresponding adjusting plates 43 to rotate. The shorter adjusting plate 43 moves from position b to position e, and the longer adjusting plate 43 moves from position c to position d. This process is the material feeding mode. Therefore, by controlling the adjusting rods 35 to move within the set height range, the shorter adjusting plate 43 can be controlled to swing back and forth within the range be and be, and the longer adjusting plate 43 can be controlled to swing back and forth within the range cd. Thus, during batching, the adjusting plates 43 can rotate around the axis of the adjusting tubes 42 to achieve radial flow and mixing of materials in the mixing drum 1. Moreover, the two sets of adjusting plates 43 can cover different radial positions of the mixing drum 1. Combined with the radial mixing range of the spiral plate 23, the radial flowability of materials in the mixing drum 1 is further improved, and the batching effect is enhanced.

[0040] according to Figure 8 The counterclockwise direction is the working direction of stirring. The adjusting plate 43 is set on the back side of the rotating direction of the adjusting tube 42, thereby reducing the rotational resistance during feeding. The axis of the adjusting tube 42 is taken as the tangent of the rotating direction of the support shaft 22. In the feeding mode, the angle between the adjusting plate 43 and the tangent is less than 45 degrees, thereby reducing the swing resistance of the adjusting plate 43.

[0041] Reference Figure 2 , Figure 3 , Figures 9 to 11 A discharge assembly 5 is installed on the support shaft 22. The discharge assembly 5 includes a connecting block 51 that slides on the support shaft 22. Two sets of support rods 52 are fixedly installed on the connecting block 51. Scrapers 53 are installed obliquely below the support rods 52, which can stir the material at the bottom of the mixing drum 1, thereby improving the mixing effect of the material at the bottom of the mixing drum 1. The radial distance between the center line of several scrapers 53 and the axis of the support shaft 22 is not equal, so that multiple sets of scrapers 53 can cover the radial stirring range of the mixing drum 1, reducing the stirring rotation resistance without reducing the stirring and batching effect of the mixing drum 1. When the support shaft 22 rotates counterclockwise, the scrapers 53 are located on the back side of the rotation direction of the support rods 52, which can reduce the rotation resistance of the scrapers 53. When the connecting block 51 slides to the bottom of the limiting groove of the support shaft 22, the scrapers 53 contact the bottom of the mixing drum 1.

[0042] A connecting sleeve 54 is rotatably installed inside the connecting block 51. A discharge pipe 55 is slidably connected inside the connecting sleeve 54. The sliding direction of the discharge pipe 55 is along the axial direction of the connecting sleeve 54. The bottom of the discharge pipe 55 communicates with the unloading pipe 12. A discharge hole 56 is opened on the discharge pipe 55. A top plate 57 is fixedly installed on the discharge pipe 55. The top plate 57 passes through the unloading pipe 12. The discharge pipe 55 is slidably connected to the unloading pipe 12 through the top plate 57. A telescopic cylinder 6 is fixedly installed on the unloading pipe 12. The output end of the telescopic cylinder 6 is fixedly connected to the top plate 57. The height of the discharge hole 56 is less than the height of the connecting sleeve 54. When the discharge pipe 55 moves upward, the discharge hole 56 can completely enter the connecting sleeve 54, thereby sealing the discharge hole 56. When the discharge pipe 55 moves upward, it can drive the connecting block 51, support rod 52 and scraper 53 to move upward. The scraper 53 is no longer in contact with the bottom of the mixing drum 1, which avoids damage to the bottom of the mixing drum 1 when rotating and mixing, and at the same time reduces the wear of the scraper 53. When the discharge pipe 55 moves downward, the discharge hole 56 is connected to the inside of the mixing drum 1. The mixed material can enter the discharge pipe 55 from the discharge hole 56 and be transported out from the discharge pipe 12 to realize the discharge process. At the same time, when the discharge pipe 55 moves to the bottom, it can pull the connecting sleeve 54, connecting block 51, support rod 52 and scraper 53 downward. At this time, the scraper 53 can contact the bottom of the mixing drum 1. When the scraper 53 rotates, it can clean the bottom of the mixing drum 1. A sealing ring groove can be opened on the inner side of the discharge pipe 12, and an annular sealing ring can be fitted inside the sealing ring groove. The sealing ring groove is located at the bottom of the discharge pipe 12, and the annular sealing ring protrudes from the sealing ring groove by less than one-quarter of its thickness. This ensures the stability of the sealing ring installation while wrapping and squeezing the outer wall of the discharge pipe 55, thereby sealing the joint between the discharge pipe 55 and the discharge pipe 12 and preventing leakage.

[0043] Working principle: The output end of the telescopic cylinder 6 drives the top plate 57 and the discharge pipe 55 to move upward. When the top of the discharge pipe 55 moves upward to contact the top of the connecting block 51, the discharge hole 56 is completely inside the connecting sleeve 54 and is in a blocked state. As the discharge pipe 55 continues to move upward, it will push the connecting block 51 to move upward along the axis of the support shaft 22. The support rod 52, scraper 53 and connecting sleeve 54 will move upward synchronously with the connecting block 51. The scraper 53 will disengage from contact with the bottom of the mixing drum 1.

[0044] The output end of the hydraulic cylinder 31 drives the support plate 32, sleeve 33, guide rod 34 and adjusting rod 35 to rise. The far end of the adjusting rod 35 moves from the bottom of the guide groove 47 to the connection between the guide groove 47 and the reversing groove 46. The near end of the adjusting rod 35 slides in the reversing groove 46. The adjusting rod 35 forces the adjusting tube 42 and the adjusting plate 43 to rotate. At this time, the near end of the adjusting plate 43 is at position c and the far end of the adjusting plate 43 is at position b. The output end of the hydraulic cylinder 31 drives the support plate 32 and the adjusting rod 35 to continue to move upward, so that the near end of the adjusting plate 43 is in the range cd and the far end of the adjusting plate 43 is in the range be, thus entering the feeding mode.

[0045] The output end of the geared motor 21 drives the support shaft 22 and the spiral plate 23 to rotate. The support shaft 22 drives the sleeve 33, guide rod 34, adjusting pipe 42, support pipe 41 and several adjusting plates 43 to rotate around the axis of the support shaft 22. The support shaft 22 drives the connecting block 51, support rod 52 and several scrapers 53 to rotate around the axis of the support shaft 22. After the material is added into the mixing drum 1 through the feed port, the spiral plate 23, adjusting pipe 42, support rod 52 and scraper 53 stir and mix the material.

[0046] The output end of the hydraulic cylinder 31 reciprocates, driving the support plate 32, sleeve 33, guide rod 34 and adjusting rod 35 to move up and down. The adjusting rod 35 forces the adjusting tube 42 to rotate, controlling the adjusting plate 43 at the near end to swing back and forth within the cd range, and controlling the adjusting plate 43 at the far end to swing back and forth within the be range, so as to radially mix the material and further improve the batching effect.

[0047] During unloading, the output end of the telescopic cylinder 6 drives the top plate 57 and the discharge pipe 55 to descend. The discharge hole 56 gradually separates from the connecting sleeve 54 and connects with the inside of the mixing drum 1. The mixture enters the discharge pipe 55 from the discharge hole 56 and is then conveyed out from the bottom of the discharge pipe 12, completing the unloading.

[0048] During cleaning, the output end of the telescopic cylinder 6 drives the top plate 57 and the discharge pipe 55 to descend. The discharge pipe 55 drives the connecting sleeve 54, connecting block 51, support rod 52, and scraper 53 to descend until the end of the scraper 53 contacts the bottom of the mixing drum 1. The output end of the hydraulic cylinder 31 drives the lifting assembly 3 to descend to its maximum position.

[0049] The near-end adjusting rod 35 moves to the bottom of the reversing groove 46, and the far-end adjusting rod 35 moves to the bottom of the guide groove 47. At this time, the near-end adjusting plate 43 rotates to position a, and the far-end adjusting plate 43 rotates to position b. The ends of the two sets of adjusting plates 43 contact the inner wall of the mixing drum 1. The output end of the reduction motor 21 drives the adjusting assembly 4 and the unloading assembly 5 to rotate around the axis of the support shaft 22, so that the adjusting plate 43 and the scraper 53 clean the material adhering to the inner wall of the mixing drum 1.
