Description

Technical Field

[0001] This invention relates to the field of rock sugar processing technology, specifically to an integrated production equipment for rock sugar crystallization and molding. Background Technology

[0002] Rock sugar, a common crystalline sucrose product, is widely used in the food and pharmaceutical industries. Its production process mainly includes sugar solution pretreatment, mixing, crystallization, separation, and drying. Traditional rock sugar production equipment typically employs a segmented design, with each process relatively independent. In the sugar solution mixing stage, existing equipment mostly uses a single mechanical stirring device. While this structure can achieve basic mixing, the relatively simple movement of the stirring blades makes it difficult to quickly and evenly distribute the sugar solution, leading to localized concentration differences. This affects the uniform growth of rock sugar crystals, easily resulting in irregular crystal morphology and internal defects. In the sugar solution filtration stage, existing equipment generally uses fixed filter screens. However, this structure is prone to filter clogging, requiring frequent shutdowns for manual cleaning, increasing maintenance costs, reducing production efficiency, and affecting production continuity. Furthermore, existing equipment also has shortcomings in controlling solution concentration and supersaturation, usually relying on manual operation or simple automated control, making precise control difficult, thus affecting the quality of rock sugar crystals and production efficiency. The existence of these problems indicates that there is still room for improvement in the structure and function of existing rock sugar production equipment, and a more efficient, precise and stable production equipment is needed to meet the technological requirements of modern rock sugar production. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides an integrated production equipment for rock sugar crystallization, which solves the problems mentioned in the background section.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an integrated production equipment for rock sugar crystallization, comprising a mounting frame, a crystallization tank fixedly mounted on the inner side of the mounting frame, a drive motor mounted on the top of the crystallization tank, a drive shaft fixedly mounted on the output end of the drive motor, a fixed frame fixedly connected to the outer middle side of the drive shaft, a drive gear fixedly connected to the inner side of the crystallization tank via multiple fixed rods, a mixing shaft movably connected to three protrusions of the fixed frame via bearings, a driven gear fixedly connected to the top of the mixing shaft, mixing blades welded to the bottom end of the mixing shaft, a spraying assembly mounted on the bottom of the drive shaft, the spraying assembly being used to spray solvent into the interior of the crystallization tank, the output end of the drive motor being connected to the spraying assembly via a transmission assembly, and a pretreatment filtration assembly mounted on the outer side of the mounting frame.

[0005] Through the above technical solution, this equipment utilizes a drive motor to rotate the mixing shaft and mixing blades, improving the mixing efficiency of the sugar solution and ensuring uniform solution distribution, thus creating favorable conditions for the uniform growth of rock sugar crystals. Simultaneously, the spraying assembly, driven by the drive motor, operates synchronously, precisely controlling the concentration and supersaturation of the solution to promote optimal rock sugar crystal formation. Furthermore, the pretreatment filtration assembly ensures that the sugar solution entering the crystallization tank is pure and free of impurities, guaranteeing the smooth progress of the subsequent crystallization process.

[0006] Preferably, the pretreatment filtration assembly includes a tank body one fixed to the outside of the mounting frame, a filter box connected to the outside of the tank body one via a pipe, a material pump installed on the outside of the mounting frame, a connecting pipe one fixedly connected to the output end of the material pump, a connecting pipe three fixedly connected to the input end of the material pump, a mounting shell fixedly connected to one end of the connecting pipe three, a connecting pipe two communicating with the outer surface of the mounting shell, and a filter screen detachably connected to the inside of the filter box.

[0007] The above technical solution ensures the purity and absence of impurities in the sugar solution by initially dissolving and filtering the raw materials for rock sugar production, providing a high-quality solution for the subsequent crystallization process and guaranteeing the normal growth of rock sugar crystals. This component utilizes a tank for dissolving and mixing, removes impurities through a filter screen in a filtration box, and uses a pump and connecting pipes to transport and filter the sugar solution, ultimately providing pure sugar solution to the crystallization tank.

[0008] Preferably, an impeller is movably connected to the inner side of the mounting housing via a rotating shaft, a drive rod is fixedly connected to the outer side of the impeller, a sliding groove is provided on the top of the filter box, a movable plate is slidably connected to the inner side of the sliding groove, a movable slot is provided on the inner side of the movable plate, the end of the drive rod is protruding and movably disposed inside the movable slot, a second drive gear is rotatably connected to the inner side of the filter box, two rack plates are slidably connected to the outer surface of the filter screen, and a cleaning plate is fixedly connected to the outer side of the rack plates.

[0009] Through the above technical solution, the impeller rotates under the drive of the sugar liquid flow, and drives the moving plate to move back and forth in the slide groove through the drive rod. Then, through the meshing transmission of the rack plate and the second drive gear, the cleaning plate is driven to slide along the outer surface of the filter screen, thereby effectively removing impurities on the filter screen, ensuring filtration efficiency, and reducing the need for manual maintenance.

[0010] Preferably, the inner side of the cleaning plate is in contact with the outer surface of the filter screen, the outer sides of the two rack plates are meshed with the outer side of the second drive gear, and the bottom end of the moving plate is fixedly connected to the top side of the upper rack plate.

[0011] The above technical solution uses a moving plate to drive a rack plate, and the meshing transmission between the rack plate and the second drive gear causes the cleaning plate to slide along the outer surface of the filter screen, thereby achieving automatic cleaning of the filter screen, preventing the accumulation of impurities, and ensuring filtration efficiency.

[0012] Preferably, the spraying assembly includes a reciprocating screw rotatably mounted at the bottom of the drive shaft, a movable plate threadedly connected to the outer side of the reciprocating screw, a limit rod slidably connected to the inner through hole of the movable plate, a rotating seat rotatably mounted on the outer middle side of the reciprocating screw, a plurality of hinge rods hinged to the outer side of the movable plate, a swing rod hinged to the end of the hinge rod, and a spray head mounted on the outer side of the swing rod.

[0013] The above technical solution uses a reciprocating screw to move the movable plate up and down, which is then driven by a hinged rod and a swing rod to enable the nozzle to swing at multiple angles. This ensures that the solvent, antisolvent, or additives sprayed into the tank are evenly distributed, thereby precisely controlling the solution concentration and supersaturation and promoting the uniform growth of rock sugar crystals.

[0014] Preferably, one end of the swing rod is hinged to the outside of the rotating seat, an annular tube is installed on the inside of the swing rod, the outer pipe of the annular tube is connected to the nozzle, and a tank body two is fixedly connected to the outside of the mounting bracket. The outer side of the tank body two is connected to the annular tube through a pipe.

[0015] The above technical solution delivers the solvent, antisolvent, or additives from the second tank to the nozzle via a ring pipe. The hinged design of the swing rod allows the nozzle to spray liquid at multiple angles during swinging, ensuring uniform distribution of the solution within the tank. This enables precise control of the solution properties and promotes uniform growth of rock sugar crystals.

[0016] Preferably, the transmission assembly includes a first synchronous pulley fixedly mounted on the output end of the drive motor, a second synchronous pulley connected to the outer side of the first synchronous pulley via a belt drive, a transmission shaft fixedly connected to the outer side of the second synchronous pulley, a first bevel gear fixedly connected to the bottom end of the transmission shaft, a connecting shaft movably connected to the outer through hole of the crystallizing tank via a bearing, a second bevel gear fixedly connected to both ends of the connecting shaft, and a third bevel gear fixedly connected to the bottom end of the reciprocating lead screw.

[0017] Through the above technical solution, the power of the drive motor is sequentially transmitted to synchronous pulley one, synchronous pulley two, drive shaft and bevel gear one, and then through the meshing transmission of bevel gear two and bevel gear three, it finally drives the reciprocating screw to rotate, realizing the multi-angle spraying function of the spraying component.

[0018] Preferably, the outer side of the second bevel gear on the left is meshed with the outer side of the first bevel gear, and the outer side of the second bevel gear on the right is meshed with the outer side of the third bevel gear.

[0019] Through the above technical solution, bevel gear two and bevel gear three on the right side mesh, driving the reciprocating lead screw to rotate. This design achieves precise power transmission, ensuring stable and efficient operation of the equipment.

[0020] Preferably, one end of the first connecting pipe is connected to the top of the crystallization tank, and one end of the second connecting pipe is connected to the top of the filter box.

[0021] Through the above technical solution, connecting pipe one and connecting pipe two are respectively connected to the crystallization tank and the filter box, forming a sugar solution conveying circuit, ensuring smooth flow of sugar solution, and realizing seamless connection between filtration and crystallization processes.

[0022] Preferably, a placement tray is provided on the inner bottom of the crystallization tank, seed crystals are placed on the inner side of the placement tray, and a discharge port is installed at the bottom of the crystallization tank.

[0023] Through the above technical solution, the placement plate is used to carry the seed crystals, which serve as the initial core for the growth of rock sugar crystals and promote the smooth progress of the crystallization process; the discharge port facilitates the discharge of rock sugar crystals after production is completed, thus achieving continuous and efficient production.

[0024] This invention provides an integrated production equipment for rock sugar crystallization. It has the following beneficial effects:

[0025] 1. This invention incorporates a drive shaft and drive gears within the crystallization tank, allowing the mixing blades to rotate simultaneously with the tank's rotation. This significantly improves mixing efficiency, ensures rapid and uniform distribution of the sugar solution, avoids localized concentration differences, and provides an ideal environment for the uniform growth of rock sugar crystals. Furthermore, the planetary mixing component drives the spraying component to work synchronously. The spraying component can inject solvents, antisolvents, or additives into the tank, achieving precise control over solution concentration and supersaturation. Simultaneously, the constantly changing nozzle angle ensures a more even distribution of the injected substances within the tank, promoting uniform nucleation and growth of rock sugar crystals and effectively preventing irregular morphology and internal defects caused by uneven solution properties.

[0026] 2. This invention achieves efficient filtration of raw sugar solution by adding a filter assembly. Simultaneously, a pump drives an impeller to rotate, cleverly moving a cleaning plate back and forth along the outer surface of the filter screen, achieving self-cleaning of the screen. The entire process requires no additional cleaning equipment, reducing energy consumption, improving filtration efficiency, ensuring production continuity, and enhancing equipment reliability and stability.

[0027] 3. This invention integrates the pretreatment, mixing, crystallization, and feeding of rock sugar raw materials, reducing manual intervention and time loss in process connections. Through the coordinated operation of all components, the footprint of this equipment is reduced, ensuring the continuity of rock sugar production. Attached Figure Description

[0038] The technical solutions in 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 a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, those skilled in the art can understand the concepts without making creative decisions.

[0039] Please see the appendix Figure 1 - Appendix Figure 9 This invention provides an integrated production equipment for rock sugar crystallization, including a mounting frame 1. A crystallization tank 2 is fixedly mounted on the inner side of the mounting frame 1. A drive motor 3 is mounted on the top of the crystallization tank 2. A drive shaft 602 is fixedly mounted on the output end of the drive motor 3. A fixing frame 605 is fixedly connected to the outer middle side of the drive shaft 602. A drive gear 601 is fixedly connected to the inner side of the crystallization tank 2 through multiple fixing rods 603. A mixing shaft 604 is movably connected to the three protrusions of the fixing frame 605 through bearings. A driven gear 606 is fixedly connected to the top of the mixing shaft 604. A mixing blade 607 is welded to the bottom end of the mixing shaft 604. A spraying assembly is mounted on the bottom of the drive shaft 602. The spraying assembly is used to spray solvent into the interior of the crystallization tank 2. The output end of the drive motor 3 is connected to the spraying assembly through a transmission assembly. A pretreatment filtration assembly is mounted on the outer side of the mounting frame 1.

[0040] Specifically, when the drive motor 3 starts, its output drives the drive shaft 602 to rotate. The rotation of the drive shaft 602 is transmitted through the fixed frame 605, causing the three mixing shafts 604 to revolve. The driven gear 606 at the top of each mixing shaft 604 meshes with the drive gear 601 fixed inside the crystallization tank 2. This meshing causes the mixing shaft 604 to rotate on its own axis while revolving around the center of the crystallization tank. The bottom end of the mixing shaft 604 is equipped with mixing blades 607. The combination of the revolution and rotation of the mixing blades 607 significantly improves the mixing efficiency of the sugar solution, ensuring that the sugar solution can be quickly and evenly distributed in the crystallization tank 2, thereby avoiding local concentration differences and providing an ideal environment for the uniform growth of rock sugar crystals.

[0041] The pretreatment filtration assembly includes a tank 401 fixed to the outside of the mounting frame 1. A filter box 404 is connected to the outside of the tank 401 via a pipe. A material pump 402 is installed on the outside of the mounting frame 1. A connecting pipe 403 is fixedly connected to the output end of the material pump 402. A connecting pipe 406 is fixedly connected to the input end of the material pump 402. A mounting shell 407 is fixedly connected to one end of the connecting pipe 406. A connecting pipe 405 communicates with the outer surface of the mounting shell 407. A filter screen 801 is detachably connected to the inside of the filter box 404. An impeller 807 is movably connected to the inner side of the mounting housing 407 via a rotating shaft. A drive rod 806 is fixedly connected to the outer side of the impeller 807. A sliding groove is provided on the top of the filter box 404. A movable plate 803 is slidably connected to the inner side of the sliding groove. A movable slot is provided on the inner side of the movable plate 803. The end of the drive rod 806 is protruding and movably disposed inside the movable slot. A drive gear 804 is rotatably connected to the inner side of the filter box 404. Two rack plates 805 are slidably connected to the outer surface of the filter screen 801. A cleaning plate 802 is fixedly connected to the outer side of the rack plates 805.

[0042] Specifically, tank 401 is used to dissolve and mix granulated sugar and water to form a sugar solution. Filter box 404 filters the sugar solution to remove impurities and ensure its purity. Pump 402 provides power to pump the sugar solution from tank 401 to filter box 404. Mounting housing 407 mounts and supports impeller 807, ensuring it rotates normally when the sugar solution flows. The impeller 807 rotates when the sugar solution flows, driving drive rod 806 to swing. Rack plate 805 moves under the action of drive gear 804, causing cleaning plate 802 to slide along the surface of filter screen 801, thus cleaning the filter screen 801.

[0043] Sugar and water are added to tank 401 to dissolve and mix, forming a sugar solution. Pump 402 is started, and the sugar solution is pumped to filter box 404. After being filtered through filter screen 801 to remove impurities, the sugar solution enters the subsequent crystallization tank 2 for further processing through connecting pipe 405, connecting pipe 406, and connecting pipe 403.

[0044] When the sugar solution flows from tank 401 to filter box 404, it drives the impeller 807 inside mounting housing 407 to rotate. The rotation of the impeller 807 is transmitted through drive rod 806, driving moving plate 803 to reciprocate within the groove at the top of filter box 404. The movement of moving plate 803, through the meshing of its rack plate 805 with drive gear 804, drives cleaning plate 802 to slide along the outer surface of filter screen 801, achieving self-cleaning of filter screen 801. This process effectively prevents filter screen 801 from clogging, ensuring filtration efficiency.

[0045] The inner side of the cleaning plate 802 is in contact with the outer surface of the filter screen 801, the outer sides of the two rack plates 805 are meshed with the outer side of the drive gear 804, and the bottom end of the moving plate 803 is fixedly connected to the top side of the upper rack plate 805.

[0046] Specifically, the inner side of the cleaning plate 802 is in close contact with the outer surface of the filter screen 801, and can slide along the surface of the filter screen 801 to clean the filter screen 801, prevent the filter screen 801 from clogging, and ensure filtration efficiency. The outer sides of the two rack plates 805 are respectively meshed with the outer sides of the drive gear. When the rack plates 805 move, they drive the drive gear to rotate. This meshing relationship converts the linear motion of the rack plates 805 into the rotational motion of the drive gear.

[0047] The spraying assembly includes a reciprocating screw 701 rotatably mounted at the bottom of a drive shaft 602. A movable plate 702 is threadedly connected to the outer side of the reciprocating screw 701. A limit rod 703 is slidably connected to the internal through hole of the movable plate 702. A rotating seat 902 is rotatably mounted on the outer side of the reciprocating screw 701. Multiple hinge rods 704 are hinged to the outer side of the movable plate 702. A swing rod 705 is hinged to the end of each hinge rod 704. A nozzle 706 is mounted on the outer side of the swing rod 705. One end of the swing rod 705 is hinged to the outer side of the rotating seat 902. An annular tube 901 is mounted on the inner side of the swing rod 705. The outer pipe of the annular tube 901 is connected to the nozzle 706. A tank 9 is fixedly connected to the outer side of the mounting bracket 1. The outer side of the tank 9 is connected to the annular tube 901 through a pipe.

[0048] Specifically, the reciprocating screw 701 is used to rotate to drive the movable plate 702 to move up and down. The up and down movement of the movable plate 702 drives the nozzle 706 to swing via the hinge rod 704. The limiting rod 703 is used to prevent the movable plate 702 from rotating, ensuring that it moves linearly along the reciprocating screw 701. The hinge rod 704 and the swing rod 705 are used to convert the linear movement of the movable plate 702 into the swing of the nozzle 706. The tank 9 is used to store solvents, antisolvents, or additives to supply the liquid required by the nozzle 706.

[0049] The drive shaft 602 drives the reciprocating screw 701 to rotate, and the movable plate 702 moves up and down along the screw. Through the transmission of the hinge rod 704 and the swing rod 705, the swing angle of the nozzle 706 changes continuously, making the sprayed material more evenly distributed. At the same time, the solvent, antisolvent, or additive in the tank 2 9 is transported to the nozzle 706 through the annular pipe 901 and sprayed into the crystallization tank 2, realizing precise control of the solution properties.

[0050] The transmission assembly includes a first synchronous pulley 501 fixedly mounted on the output end of the drive motor 3. A second synchronous pulley 502 is connected to the outer side of the first synchronous pulley 501 via a belt drive. A drive shaft 503 is fixedly connected to the outer side of the second synchronous pulley 502. A first bevel gear 504 is fixedly connected to the bottom end of the drive shaft 503. A connecting shaft 505 is movably connected to the outer through-hole of the crystallizing tank 2 via a bearing. Both ends of the connecting shaft 505 are fixedly connected to second bevel gears 506. A third bevel gear 507 is fixedly connected to the bottom end of the reciprocating screw 701. The outer side of the left second bevel gear 506 meshes with the outer side of the first bevel gear 504, and the outer side of the right second bevel gear 506 meshes with the outer side of the third bevel gear 507.

[0051] Specifically, when the drive motor 3 starts, its output drives synchronous pulley 501 to rotate. Synchronous pulley 501 transmits power to synchronous pulley 502 via a belt, causing synchronous pulley 502 to rotate synchronously. The rotation of synchronous pulley 502 drives the drive shaft 503, which is fixedly connected to it, to rotate. The bottom end of the drive shaft 503 is fixedly connected to bevel gear 504, so the rotation of the drive shaft 503 further drives the bevel gear 504 to rotate.

[0052] Bevel gear 1 504 meshes with bevel gear 2 506 on the left, so the rotation of bevel gear 1 504 drives the rotation of bevel gear 2 506 on the left. Bevel gear 2 506 on the left is fixedly connected to one end of connecting shaft 505, so connecting shaft 505 rotates accordingly. The other end of connecting shaft 505 is fixedly connected to bevel gear 2 506 on the right, which meshes with bevel gear 3 507. Therefore, when connecting shaft 505 rotates, bevel gear 2 506 on the right drives bevel gear 3 507 to rotate. Bevel gear 3 507 is fixedly connected to the bottom end of reciprocating screw 701, ultimately driving reciprocating screw 701 to rotate.

[0053] One end of connecting pipe 403 is connected to the top of crystallization tank 2, and one end of connecting pipe 405 is connected to the top of filter box 404. A placement tray is provided on the inner bottom of crystallization tank 2, and seed crystals are placed on the inner side of the placement tray. A discharge port is installed at the bottom of crystallization tank 2.

[0054] Specifically, connecting pipe 1 (403) and connecting pipe 2 (405) are responsible for transporting the filtered sugar solution from the filter box (404) to the crystallization tank (2). Seed crystals provide the starting nucleus for the growth of rock sugar crystals.

[0055] Working principle: When using this device, first add granulated sugar and water to tank 401 to dissolve and mix them to form a sugar solution. Start the pump 402, and the sugar solution is pumped through the pipeline to the filter box 404. After being filtered by the filter screen 801, the sugar solution enters the crystallization tank 2 through connecting pipe 405, connecting pipe 406, and connecting pipe 403 in sequence.

[0056] When the sugar solution flows from connecting pipe 2 405 into connecting pipe 3 406, it drives the impeller 807 inside the mounting housing 407 to rotate. The rotation of the impeller 807 drives the moving plate 803 to reciprocate within the groove via the drive rod 806. The movement of the moving plate 803 is transmitted through the meshing of the rack plate 805 and the drive gear 2 804, causing the cleaning plate 802 to slide along the outer surface of the filter screen 801, achieving self-cleaning of the filter screen 801 without the need for additional cleaning equipment, reducing energy consumption and improving filtration efficiency.

[0057] After the sugar solution enters the crystallization tank 2, the drive motor 3 is started to drive the drive shaft 602 to rotate. The drive shaft 602 drives the mixing shaft 604 and the mixing blades 607 to revolve via the fixed frame 605. At the same time, the driven gear 606 meshes with the drive gear 601, causing the mixing shaft 604 and the mixing blades 607 to rotate, ensuring that the sugar solution is rapidly and evenly distributed, avoiding local concentration differences, and providing an ideal environment for the uniform growth of rock sugar crystals.

[0058] The drive motor 3 also drives the bevel gear 504 to rotate via synchronous pulley 501, synchronous pulley 502, and drive shaft 503. Bevel gear 504 meshes with bevel gear 506, and through connecting shaft 505 and bevel gear 507, drives the reciprocating screw 701 to rotate. The reciprocating screw 701 drives the movable plate 702 to move up and down, and through hinge rod 704 and swing rod 705, causes the nozzle 706 to swing at multiple angles. The solvent, antisolvent, or additives in tank 2 9 enter the annular pipe 901 through pipes, and are then sprayed out through nozzle 706, precisely controlling the solution concentration and supersaturation to promote uniform nucleation and growth of rock sugar crystals, preventing irregular shapes and internal defects in the crystals due to uneven solution properties.

[0059] Finally, the heating and evaporation system of crystallization tank 2 is activated to evaporate the sugar solution, and the seed crystals on the placement tray are used to promote the crystallization of rock sugar. After crystallization is complete, the discharge port at the bottom of crystallization tank 2 is opened to discharge the rock sugar crystals.
