Description

Technical Field

[0001] This utility model belongs to the technical field of stirring devices, specifically a mixing and stirring device for the production and processing of rock sugar. Background Technology

[0002] Mixing and stirring is one of the key steps in the production of rock sugar, and its effect directly affects the quality of rock sugar and production efficiency. With the continuous improvement of consumers' requirements for the quality of rock sugar and the increasing market demand for rock sugar production, higher requirements are also being placed on the performance of mixing and stirring equipment in rock sugar production and processing.

[0003] Currently, most common rock sugar production and processing mixing and stirring devices on the market adopt a single stirring structure, that is, a motor drives a stirring rod to stir. This device can achieve the mixing of sugar raw materials with other additives to a certain extent. Some more advanced existing devices may increase the number of stirring blades or change the shape of the blades in an attempt to improve the stirring effect. In terms of heating method, a heating jacket is usually set on the outside of the mixing tank to heat the material inside the tank through heat conduction.

[0004] The existing stirring device has a relatively simple stirring structure, which makes it difficult for the material to form complex fluid movements during the stirring process. The contact opportunities between sugar molecules and water molecules are limited, resulting in a slow sugar dissolution rate and low production efficiency. In addition, the stirring rod cannot fully adhere to the barrel wall, which makes the material near the barrel wall easy to accumulate and clump. This not only causes material waste but may also affect the production quality of subsequent batches of rock sugar. Furthermore, cleaning the residual material on the barrel wall increases the labor intensity and time cost for workers. Utility Model Content

It solves the problems of the simple mixing structure of existing stirring devices, which makes it difficult for materials to form complex fluid movements during the mixing process. The limited contact opportunities between sugar molecules and water molecules result in slow sugar dissolution and low production efficiency. In addition, the stirring rod cannot fully adhere to the barrel wall, which makes the material near the barrel wall easy to accumulate and clump. This not only causes material waste but may also affect the production quality of subsequent batches of rock sugar. Furthermore, cleaning the residual material on the barrel wall increases the labor intensity and time cost for workers.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing and stirring device for rock sugar production and processing, comprising an outer barrel, an inner barrel fixedly connected inside the outer barrel, a heating tube installed between the outer barrel and the inner barrel, a top plate snapped onto the top of the inner barrel, limit blocks fixedly installed on the top of the top plate in a symmetrical structure, a fixing block connected to the top of the limit block, a motor fixedly connected to the top of the fixing block, a first rotating block coaxially fixedly connected to the output end of the motor, the first rotating block being located between the limit blocks and rotatably connected to the limit blocks, a first transmission rod fixedly connected to the bottom of the first rotating block, a first stirring rod fixedly installed at the bottom of the first transmission rod, and a toothed ring provided inside the first rotating block.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-6 As shown, this utility model provides a technical solution for a mixing and stirring device for rock sugar production and processing:

[0023] The system includes an outer tub 1, an inner tub 4 fixedly connected to the outer tub 1, a heating tube 21 installed between the outer tub 1 and the inner tub 4, a top plate 16 snapped onto the top of the inner tub 4, limit blocks 6 symmetrically fixedly installed on the top of the top plate 16, a fixing block 7 connected to the top of the limit block 6, a motor 8 fixedly connected to the top of the fixing block 7, a first rotating block 9 coaxially fixedly connected to the output end of the motor 8, the first rotating block 9 being located between the limit blocks 6 and rotatably connected to the limit blocks 6, a first transmission rod 22 fixedly connected to the bottom of the first rotating block 9, a first stirring rod 11 fixedly installed at the bottom of the first transmission rod 22, a gear ring provided inside the first rotating block 9, and a second drive gear 25 meshing inside the first rotating block 9. A second driven gear 26 is meshed with the outer side of gear 25. A second rotating block 10 is rotatably connected inside the top plate 16. A gear ring is provided inside the second rotating block 10, and the second driven gear 26 meshes with the gear ring inside the second rotating block 10. The second driving gear 25 and the second driven gear 26 are located inside the first rotating block 9 and the second rotating block 10. A second transmission rod 23 is fixedly connected to the bottom of the second rotating block 10. The second transmission rod 23 is located outside the first transmission rod 22 and is rotatably connected to the first transmission rod 22. A second stirring rod 12 is fixedly connected to the outer side of the second transmission rod 23. The first stirring rod 11 is in contact with the inner wall of the inner barrel 4. The second stirring rod 12 has a spiral structure and is located at the center of the inner barrel 4.

[0024] Specifically, in use, the sugar raw materials to be processed are first added to the inner barrel 4, and then the motor 8 is turned on. The output end of the motor 8 starts to rotate, driving the first rotating block 9, which is fixedly connected to it on the same axis, to rotate. Since the first rotating block 9 is rotatably connected to the limiting block 6, the limiting block 6 plays the role of supporting and positioning the first rotating block 9, ensuring its stable rotation. When the first rotating block 9 rotates, its internal gear ring drives the second drive gear 25, which meshes with it, to rotate. The second drive gear 25 then drives the second driven gear 26, which meshes with it on the outside, to rotate. The second driven gear 26 meshes with the gear ring inside the second rotating block 10. This drives the second rotating block 10 to rotate. Due to the characteristics of gear transmission, the first rotating block 9 and the second rotating block 10 will rotate in opposite directions. The first transmission rod 22, which is fixedly connected to the bottom of the first rotating block 9, rotates together with the first rotating block 9. The first stirring rod 11 at the bottom of the first transmission rod 22 also rotates accordingly. The first stirring rod 11 is in contact with the inner wall of the inner barrel 4, stirring the sugar raw materials near the inner wall of the inner barrel 4. The second transmission rod 23, which is fixedly connected to the bottom of the second rotating block 10, rotates with the second rotating block 10. The second stirring rod 12 on the outside of the second transmission rod 23 also begins to rotate. 2 is a spiral structure located at the center of the inner barrel 4. It rotates in the opposite direction to the first stirring rod 11, stirring the sugar material at the center of the barrel. During stirring, the heating tube 21 heats the space between the outer barrel 1 and the inner barrel 4, transferring heat to the sugar material in the inner barrel 4 to accelerate the melting of the sugar. A motor 8 provides the driving force. Utilizing the meshing relationship between the first rotating block 9, the second rotating block 10, and the second driving gear 25 and the second driven gear 26, the first stirring rod 11 and the second stirring rod 12 rotate in opposite directions. This reverse rotation stirring method can create a complex... The complex fluid motion allows the sugar raw materials in the inner barrel 4 to be fully mixed under the action of forces in different directions, greatly increasing the contact opportunities between sugar molecules and water molecules, accelerating the dissolution rate of sugar, and improving production efficiency. The first stirring rod 11 is in contact with the inner wall of the inner barrel 4, which can effectively prevent the sugar raw materials from accumulating and clumping on the inner wall, ensuring that the sugar near the wall of the inner barrel 4 can also be fully heated and stirred. The spiral structure of the second stirring rod 12 is located at the center of the inner barrel 4, which can generate axial stirring force, so that the sugar raw materials in the center of the inner barrel 4 can also be fully stirred and mixed, further improving the uniformity of stirring and the melting rate of sugar.

[0025] The outer barrel 1 is rotatably connected to the two sides of the support frame 2. The bottom of the support frame 2 is fixedly installed with the base 3. The outer barrel 1 is fixedly connected to the first driven gear 20. The support frame 2 is rotatably connected to the first driven gear 20. The support frame 2 is fixedly installed to the outside of the support frame 2 and is used in conjunction with the first driven gear 20. The protective shell 13 is fixedly installed to the outside of the support frame 2 and is used in conjunction with the first driven gear 19 and the first driven gear 20. The protective shell 13 is rotatably connected to the outside of the protective shell 13. The rocker wheel 14 is fixedly connected to the rocker wheel 14 and the first drive gear 19. The inner barrel 4 and the top plate 16 are provided with an inlet 18. The top side of the inner barrel 4 is provided with a discharge port 5 that is used in conjunction with the inlet 18.

[0026] Specifically, the outer barrel 1 is rotatably connected to the support frame 2 on both sides. By rotating the outer barrel 1, the tilt angle of the inner barrel 4 can be flexibly adjusted. The operator can rotate the rocker wheel 14 according to the actual production needs. The rotation of the outer barrel 1 can be achieved through gear transmission, which reduces labor intensity. At the same time, the protective shell 13 protects the first drive gear 19 and the first driven gear 20, preventing dust, debris and other objects from entering the gear transmission system, ensuring the stability and reliability of the transmission, and extending the service life of the equipment. It can adjust the distribution of materials during feeding and stirring, or make the materials discharge more smoothly from the discharge port 5 during discharge. This greatly improves the operational flexibility of the device, making the rock sugar production process more efficient and convenient. The inlet 18 and the discharge port 5 are set so that feeding and discharging can be smoother.

[0027] Both the outer barrel 1 and the inner barrel 4 are made of stainless steel. An electrical distribution box 15 for use with the heating tube 21 is fixedly installed on the outside of the outer barrel 1. The bottom of both the outer barrel 1 and the inner barrel 4 are circular. The first stirring rod 11 has chamfers on both sides and contacts the inner wall of the inner barrel 4. A first support block 17 is installed on the top of the top plate 16. The first support block 17 is rotatably connected to the top of the second driven gear 26. A second support block 24 is fixedly installed in the limiting block 6. The second support block 24 is rotatably connected to the bottom of the second drive gear 25. A limiting ring 27 is fixedly connected to the outside of the second rotating block 10. An active groove for use with the limiting ring 27 is opened in the top plate 16.

[0028] Specifically, the stainless steel inner barrel 4 and its circular bottom structure ensure hygiene and safety during the rock sugar production process, preventing product contamination. During stirring, the first stirring rod 11 fits better against the inner wall of the inner barrel 4, allowing for more thorough mixing. After stirring, the circular bottom facilitates the smooth flow of material to the discharge port 5 under gravity, reducing material residue and facilitating discharge and equipment cleaning. The chamfered design allows the first stirring rod 11 to better scrape the material adhering to the inner wall of the inner barrel 4, preventing material from sticking to the wall and ensuring full participation of the material in the stirring process. This further improves the uniformity and thoroughness of the stirring, helping to accelerate the melting and mixing of sugar. Furthermore, the first support block 17 and the second support block 24 enable the second drive gear 25 and the second driven gear 26 to rotate smoothly. The cooperation between the movable groove and the limiting ring 27 provides good guidance for the rotation of the second rotating block 10, making its rotation smoother, reducing friction and resistance during rotation, improving rotation efficiency, and also helping to reduce equipment energy consumption.

[0029] The working principle of this utility model is as follows:

[0030] First, the operator adds the sugar raw materials to be processed into the inner barrel 4 through the inlet 18 opened between the inner barrel 4 and the top plate 16. Both the outer barrel 1 and the inner barrel 4 are made of stainless steel, which can ensure the hygiene and safety of the rock sugar production process and avoid product contamination.

[0031] Next, the motor 8 is turned on. The output of the motor 8 drives the first rotating block 9, which is coaxially fixed to it, to rotate. The first rotating block 9 is located between and rotatably connected to the limiting blocks 6. The limiting blocks 6 provide support and positioning to ensure the stable rotation of the first rotating block 9. The gear ring inside the first rotating block 9 drives the second driving gear 25, which meshes with it, to rotate. The second driving gear 25 drives the second driven gear 26, which meshes with it on the outside, to rotate. The second driven gear 26 meshes with the gear ring inside the second rotating block 10, driving the second rotating block 10 to rotate. Due to the gear transmission characteristics, the first rotating block 9 and the second rotating block 10 rotate in opposite directions. The first transmission rod 22 at the bottom of the first rotating block 9 rotates with it, driving the first stirring rod 11 at the bottom of the first transmission rod 22 to rotate. The first stirring rod 11 is in contact with the inner wall of the inner barrel 4, stirring the sugar raw materials near the inner wall. The second transmission rod 23 at the bottom of the second rotating block 10 rotates with it, driving the second transmission rod 23 to rotate. The second stirring rod 12 on the outer side rotates. The second stirring rod 12 has a spiral structure and is located at the center of the inner barrel 4. It rotates in the opposite direction to the first stirring rod 11, stirring the sugar raw material at the center of the barrel. The chamfered design on both sides of the first stirring rod 11 can better scrape the material on the wall of the inner barrel 4, preventing it from sticking to the wall and improving the uniformity of stirring. The heating tube 21 is controlled by the electrical distribution box 15 on the outer side of the outer barrel 1. The heating tube 21 heats the space between the outer barrel 1 and the inner barrel 4. The heat is transferred to the sugar raw material in the inner barrel 4, accelerating the melting of the sugar. The first support block 17 on the top of the top plate 16 is rotatably connected to the top of the second driven gear 26. The second support block 24 inside the limiting block 6 is rotatably connected to the bottom of the second drive gear 25, ensuring that the second drive gear 25 and the second driven gear 26 rotate smoothly. The limiting ring 27 on the outer side of the second rotating block 10 cooperates with the movable groove inside the top plate 16 to provide guidance for the rotation of the second rotating block 10, making its rotation smoother and reducing energy consumption.

[0032] It is worth mentioning that the outer barrel 1 is rotatably connected to the support frame 2 on both sides. The support frame 2 has a base 3 at the bottom to provide stable support. The operator rotates the rocker wheel 14 on the outside of the protective shell 13, which drives the first drive gear 19 to rotate through the connecting shaft. The first drive gear 19 drives the first driven gear 20 that meshes with it to rotate, thereby realizing the rotation of the outer barrel 1 and flexibly adjusting the tilt angle of the inner barrel 4. During the feeding and stirring process, the material distribution state can be adjusted, and the material can be discharged more smoothly from the discharge port 5 when discharging. The protective shell 13 protects the gear transmission system and ensures the stability and reliability of the transmission.

[0033] Finally, after mixing, rotate the outer barrel 1 to tilt the inner barrel 4 as needed. Utilizing the circular structure at the bottom of the inner barrel 4, the material flows smoothly to the discharge port 5 under the action of gravity, reducing material residue and facilitating discharge and subsequent equipment cleaning.

[0034] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
