Technical Field
[0001] This utility model belongs to the field of screening device technology, specifically a rock sugar screening and sorting device. Background Technology
[0002] In the rock sugar production process, rock sugar will produce various particle sizes during the shaping stage. In order to meet the diverse needs of different customers for rock sugar particle size and to improve the quality and market competitiveness of rock sugar products, precise screening and sorting are particularly important. From the purchase of rock sugar by food processing companies for different uses such as cooking and beverages, to the preference of retail market consumers for rock sugar of different particle sizes, rock sugar production companies are required to have efficient and precise screening and sorting capabilities to achieve reasonable grading and classification of rock sugar.
[0003] Currently, the most common rock sugar screening and sorting devices on the market are vibrating screens and drum screens. Vibrating screens typically use a motor to drive an eccentric block to vibrate, causing the rock sugar placed on the screen to be screened under the action of vibration. Its structure is relatively simple, consisting of a screen, a vibrating motor, and a support structure. Drum screens, on the other hand, use a rotating drum to make the rock sugar roll on the surface of the screen inside the drum, thus separating rock sugar of different particle sizes. They generally include components such as a rotating drum, a drive device, and a support frame.
[0004] During operation, existing vibrating screens are prone to loosening of the support structure due to the large impact force generated by the motor vibration. The connection between the screen and the frame may also be displaced or damaged, affecting the normal operation and service life of the equipment. During the rotation of the drum screen, if the rock sugar material is unevenly distributed, the drum will generate a large eccentric load, which will put great pressure on the drive device and support frame, increasing the risk of equipment failure. Utility Model Content
[0005] To overcome the above-mentioned defects, this utility model provides a rock sugar screening and sorting device, which solves the problem that in the operation of existing vibrating screens, the large impact force generated by motor vibration can easily lead to loosening of the support structure, and the connection between the screen and the frame may also be displaced or damaged, affecting the normal operation and service life of the equipment. In addition, in the rotation of the drum screen, if the rock sugar material is unevenly distributed, the drum will generate a large eccentric load, which will put great pressure on the drive device and the support frame.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rock sugar sieving and sorting device, comprising a main body, the main body including a first sieving disc, a second sieving disc, and a third sieving disc, multiple sets of support blocks fixedly installed on the outer side of the second sieving disc, support legs fixedly connected to the bottom of the support blocks, the first sieving disc slidingly connected to the second sieving disc and the third sieving disc, and a collection hopper fixedly connected to the bottom of the third sieving disc, a first connecting plate fixedly connected to the outer side of the bottom of the first sieving disc, and a second connecting plate fixedly connected to the outer side of the top of the third sieving disc, a lifting mechanism provided between the first connecting plate and the second connecting plate, the lifting mechanism including a gas storage tank, an air inlet, a movable rod, and a piston block, the gas storage tank fixed to the outer side of the second sieving disc, and the piston block located symmetrically inside the gas storage tank, the movable rod fixed to both ends of the piston block, the movable rod being fixedly connected to the first connecting plate and the second connecting plate respectively, and the air inlet being opened on the outer side of the gas storage tank.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0022] like Figures 1-6As shown, this utility model provides a technical solution for a rock sugar sieving and sorting device:
[0023] The system includes a main body 1, which comprises a first screening disc 101, a second screening disc 102, and a third screening disc 103. Multiple sets of support blocks 13 are fixedly installed on the outer side of the second screening disc 102, and support legs 2 are fixedly connected to the bottom of each support block 13. The first screening disc 101, the second screening disc 102, and the third screening disc 103 are slidably connected, and a hopper 104 is fixedly connected to the bottom of the third screening disc 103. A first connecting plate 3 is fixedly connected to the outer bottom of the first screening disc 101, and a third connecting plate 2 is fixedly connected to the outer top of the third screening disc 103. The second connecting plate 12 has a lifting mechanism 4 between the first connecting plate 3 and the second connecting plate 12. The lifting mechanism 4 includes an air storage tank 401, an air inlet 402, a movable rod 403, and a piston block 404. The air storage tank 401 is fixed to the outside of the second screening plate 102, and the piston block 404 is located inside the air storage tank 401 in a symmetrical structure. The movable rod 403 is fixed to both ends of the piston block 404. The movable rod 403 is fixedly connected to the first connecting plate 3 and the second connecting plate 12 respectively. An air inlet 402 is opened on the outside of the air storage tank 401.
[0024] Specifically, during use, an external air source device inputs gas into the air storage tank 401 through the air inlet 402. The air storage tank 401 begins to store gas and gradually builds up air pressure, which is the starting point for the operation of the entire device. The continuously increasing air pressure inside the air storage tank 401 drives the internal piston block 404 to move. Since the piston block 404 exists in the air storage tank 401 with a symmetrical structure, the air pressure on both sides is uniform, and it will move synchronously to both ends. The movable rod 403, which is fixedly connected to both ends of the piston block 404, moves with the movement of the piston block 404. The movable rod 403 plays the role of transmitting power. The piston block 404 transmits its linear motion. The two ends of the movable rod 403 are fixedly connected to the first connecting plate 3 and the second connecting plate 12, respectively. Therefore, the movement of the movable rod 403 will cause the first connecting plate 3 and the second connecting plate 12 to move relative to each other, thereby causing the first sieving plate 101 and the third sieving plate 103 to move up and down relative to each other. This up-and-down relative movement of the first sieving plate 101 and the third sieving plate 103 produces a vibration effect, which is used to sieve the rock sugar. Simultaneously, due to the vibration of the first sieving plate 101, the second sieving plate 102, and the third sieving plate 103... There is a connection between the two screens. The second screening disc 102 is also affected by the vibration of the first screening disc 101 and the third screening disc 103, producing a small amplitude vibration, which further assists in the screening of rock sugar. After screening, rock sugar of different specifications falls below through the corresponding screening discs. Finally, the collecting hopper 104, which is fixedly connected to the bottom of the third screening disc 103, collects the rock sugar with different screening results. The vibration generated by the relative up-and-down movement of the first screening disc 101 and the third screening disc 103 can make the rock sugar roll and jump fully on the screening discs, effectively avoiding the sticking and clogging between the rock sugar particles. By plugging the sieve holes, the accuracy and efficiency of sieving are improved, ensuring that rock sugar of different particle sizes can accurately pass through the corresponding sieve holes. The small-amplitude vibration of the second sieve disc 102 can further disperse the aggregated rock sugar, making the rock sugar more evenly distributed during the sieving process, thereby improving the overall sieving effect. By controlling the air intake volume and air intake pressure of the air inlet 402, the lifting amplitude and frequency of the first sieve disc 101 and the third sieve disc 103 can be precisely adjusted. In this way, the vibration intensity and frequency can be flexibly adjusted according to the particle size distribution, shape characteristics, etc. of different batches of rock sugar to achieve the best sieving effect.
[0025] A first filter screen 14, a second filter screen 15, and a third filter screen 16 are fixedly connected to the inner sides of the first screening disc 101, the second screening disc 102, and the third screening disc 103, respectively. A first discharge port 5 for use with the first filter screen 14 is opened on the outer side of the first screening disc 101. A second discharge port 6 for use with the second filter screen 15 is opened on the outer side of the second screening disc 102. A third discharge port 7 for use with the third filter screen 16 is opened on the outer side of the third screening disc 103. A fourth discharge port 105 is opened at the bottom of the collecting hopper 104. The first filter screen 14, the second filter screen 15, and the third filter screen 16 are all in an inclined state, and the filter holes of the first filter screen 14 are larger than the filter holes of the second filter screen 15, and the filter holes of the second filter screen 15 are larger than the filter holes of the third filter screen 16.
[0026] Specifically, the inclined filter screen allows the sieved rock sugar to slide automatically along the surface of the screen towards the outlet under gravity, eliminating the need for an additional power source. This saves energy and equipment costs, while also improving sieve efficiency and making the entire sieve process smoother. It prevents rock sugar from accumulating on the screen, reducing the likelihood of clogging. If the screen is horizontal, material may accumulate in certain areas, causing the screen openings in those areas to be covered by a large amount of material, affecting the sieve effect. The inclined screen allows the material to slide down quickly, keeping the screen openings clear and ensuring continuous and stable sieve operation. The inclined screen also increases the effective sieve area within a limited space compared to a horizontal screen. The inclined filter screen extends vertically, increasing screening capacity without increasing equipment footprint and enabling the equipment to handle larger material flows. The design of the first filter screen 14 (larger apertures than the second filter screen 15), and the second filter screen 15 (larger apertures than the third filter screen 16), allows for multi-stage screening of rock sugar, precisely classifying it according to different particle sizes. The first filter screen 14 first screens out larger particles; those that don't pass through the first filter screen 14 continue screening through the second filter screen 15 to obtain medium-sized particles; and finally, the third filter screen 16 yields smaller particles. This design meets the diverse needs of different users for rock sugar particle sizes.
[0027] The bottom of the support leg 2 is fixedly connected to the base plate 8. Multiple sets of sliders 9 are fixedly installed on the outside of the hopper 104. The support leg 2 has a movable groove 11 that works with the sliders 9. A spring 10 is fixedly connected between the bottom of the slider 9 and the movable groove 11. The bottom of the first screening disc 101, the second screening disc 102 and the third screening disc 103 are all fixedly connected to the protruding rings 17. The top of the first screening disc 101, the second screening disc 102 and the third screening disc 103 are all provided with sliding grooves 18 that work with the protruding rings 17.
[0028] Specifically, the cooperation between the convex ring 17 and the sliding groove 18 ensures the accurate relative position of the first screening disc 101, the second screening disc 102, and the third screening disc 103 during installation and use, playing a good positioning role. At the same time, when the screening discs vibrate or move relative to each other, the convex ring 17 slides in the sliding groove 18, providing precise guidance for the movement of the screening discs, allowing them to move in a predetermined direction and trajectory, ensuring the stability and reliability of the screening operation. The spring 10 is connected between the slider 9 and the movable groove 11, and can play a good buffering and shock absorption role when the hopper 104 is subjected to vibration or impact. When the vibration of the screening disc is transmitted to the hopper 104, the spring 10 can absorb and consume some energy through compression and extension, reducing the vibration amplitude of the hopper 104, thereby protecting the hopper 104 itself and the components connected to it, and preventing damage or loosening caused by excessive vibration.
[0029] The working principle of this utility model is as follows:
[0030] First, a first filter screen 14, a second filter screen 15, and a third filter screen 16 are fixed to the inner sides of the first screening disc 101, the second screening disc 102, and the third screening disc 103, respectively, and all the filter screens are inclined. The pores of the first filter screen 14 are larger than those of the second filter screen 15, and the pores of the second filter screen 15 are larger than those of the third filter screen 16. When rock sugar is placed on the first screening disc 101, under its own weight and the vibration generated by the operation of the device, the rock sugar rolls and slides on the inclined filter screen. Larger particles of rock sugar are intercepted by the first filter screen 14 and discharged through the first outlet 5. Smaller particles of rock sugar pass through the first filter screen 14 and continue to be screened on the second filter screen 15 of the second screening disc 102. Rock sugar that fits the particle size range of the second filter screen 15 is discharged through the second outlet 6. Similarly, the smallest particles of rock sugar pass through the third filter screen 16 and are discharged through the third outlet 7, achieving multi-stage screening and precise particle size classification of the rock sugar.
[0031] Secondly, a first connecting plate 3 is fixed to the outer bottom of the first screening disc 101, and a second connecting plate 12 is fixed to the outer top of the third screening disc 103. A lifting mechanism 4 is set between the two. The air storage tank 401 of the lifting mechanism 4 is fixed to the outer side of the second screening disc 102. An external air source inputs gas into the air storage tank 401 through the air inlet 402. The gas pressure pushes the piston block 404 in the air storage tank 401 to move to both ends, which drives the movable rod 403 fixed at both ends of the piston block 404 to move. This causes the first connecting plate 3 and the second connecting plate 12 to move relative to each other, causing the first screening disc 101 and the third screening disc 103 to move up and down relative to each other. The resulting vibration is transmitted to the second screening disc 102, so that all three screening discs vibrate. This vibration helps the rock sugar to roll and jump fully on the filter screen, avoiding sticking and clogging of the sieve holes, and improving screening efficiency and accuracy.
[0032] It is worth mentioning that the tops of the first screening disc 101, the second screening disc 102, and the third screening disc 103 are all provided with sliding grooves 18, and the bottoms are all fixedly connected with convex rings 17. The convex rings 17 cooperate with the sliding grooves 18. This design not only provides precise positioning for the installation of the screening discs, but also ensures the accurate relative position of the screening discs during operation, provides guidance for the movement of the screening discs, enhances structural stability, and ensures that the filter screens on each screening disc maintain a relatively fixed position, thereby ensuring the screening effect. Multiple sets of sliding blocks 9 are fixed to the outside of the collecting hopper 104 for support. A movable groove 11 is provided inside the leg 2 to cooperate with the slider 9. A spring 10 is fixedly connected between the bottom of the slider 9 and the movable groove 11. When the vibration of the screening disc is transmitted to the collection hopper 104, the spring 10 plays a buffering and shock-absorbing role, reducing the vibration amplitude of the collection hopper 104 and protecting the collection hopper 104 and its connected parts. At the same time, the slider 9 can move in the movable groove 11. Combined with the elasticity of the spring 10, the collection hopper 104 can adaptively adjust according to the actual situation such as uneven material distribution, improve the stability of equipment operation, and reduce vibration and noise.
[0033] Finally, the rock sugar, after being screened by each screening disc, falls into the collection hopper 104, which is fixedly connected to the bottom of the third screening disc 103. The bottom of the collection hopper 104 is provided with a fourth discharge port 105. The collected rock sugar is discharged from the fourth discharge port 105, completing the entire rock sugar screening and sorting process.
[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.
