Description

Technical Field

[0001] This utility model relates to the field of sugar boiling and crystallization technology, and in particular to a sampler for a sugar boiling and crystallization tank. Background Technology

[0002] The sugar boiling crystallization tank is one of the core pieces of equipment in the sugar-making process. It is mainly used to supersaturate concentrated sugar syrup under specific temperature, vacuum, and stirring conditions, promoting the precipitation and continuous growth of sucrose crystals. This is a crucial step in achieving sugar crystallization, increasing sugar yield, and controlling crystal particle size. The key to sugar boiling crystallization is maintaining the sugar solution in an appropriate supersaturated state, ensuring continuous crystal growth while preventing excessive spontaneous nucleation that would lead to small crystals and reduced quality. The entire process typically consists of multiple stages, including feeding, heating and evaporation, crystal growth, and discharging. Throughout this process, it is necessary to monitor parameters such as the sucrose content, purity, crystal size, and morphology of the sugar solution in real time to ensure that the crystallization process proceeds stably according to the predetermined process curve.

[0003] In practice, existing technologies generally require manual sampling using a handheld sampling spoon or tube from the top or side of the tank. Since the sugar inside the tank is already in a crystallized state, it is inconvenient to manually remove samples from the hard crystallized sugar, which greatly reduces the sampling rate. Therefore, in view of the many shortcomings of existing technologies, we urgently need an innovative sampler for sugar boiling crystallization tanks to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a sampler for a sugar crystallization tank, which solves the problem that in the prior art, samples are generally taken manually from the top or side of the tank by hand using a sampling spoon or sampling tube. Since the sugar in the tank is already in a crystallized state, it is not convenient to take the sample from the hard crystallized sugar by hand, which greatly reduces the sampling rate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sampler for a sugar boiling crystallization tank includes a support plate, a support plate at the bottom of the support plate, and a first cylinder fixedly connected to one side of the top of the support plate by bolts. The output shaft of the first cylinder passes through the top of the support plate and is fixedly connected to it. Connecting plates are slidably connected to both sides of the bottom of the support plate. A drive motor is fixedly connected to one side of each of the two connecting plates by bolts, and a drill rod is rotatably connected to the other side of each of the two connecting plates. One end of the drill rod passes through the connecting plate and is connected to the output shaft of the drive motor via a bearing sleeve. A second support plate is fixedly connected to the bottom of each of the two connecting plates, and a first support plate is provided on one side of each of the two second support plates. A telescopic belt is fixedly connected between the first support plate and the second support plate, and the telescopic belt is located at the bottom of the drill rod.

[0007] Preferably, a number of elastic rods are fixedly connected to one side of each of the two first support plates, and one end of each elastic rod is fixedly connected to one side of each of the two second support plates.

[0008] Preferably, an electric slider is fixedly connected to the top of each of the two connecting plates, and the two electric sliders are slidably connected to the support plate through a groove.

[0009] Preferably, telescopic rods are fixedly connected to both sides of the top of the support plate, and the top ends of the two telescopic rods are fixedly connected to the bottom of the bearing plate.

[0010] Preferably, the bottom two sides of the support plate are provided with arc-shaped plates, and the top of the two arc-shaped plates are fixedly connected with sliding blocks, and the two sliding blocks are slidably connected to the support plate through sliding grooves.

[0011] Preferably, a second cylinder is fixedly connected to both sides of the support plate, and the output shafts of the two second cylinders pass through one side of the support plate, and one end of the output shafts of the two second cylinders is fixedly connected to one side of the two sliding blocks respectively.

[0012] This utility model has the following beneficial effects:

[0013] The combination of the support plate and the bearing plate enables rapid installation and sealed positioning of the sampling device on the top of the tank, avoiding the problem of limited space for deep sampling that is common with traditional manual hand tools, thus improving the adaptability and stability of the equipment. The support plate, as the main support component, is inserted into the tank, providing a reliable installation foundation for subsequent sampling components. Two connecting plates are slidably connected to the bottom sides of the support plate, and the first plate can be adjusted laterally to fit against the inner wall of the tank, enhancing structural stability during sampling and preventing equipment displacement due to vibration or resistance. The drive motor drives the drill rod to rotate, using mechanical drilling to cut and sample the crystallized hard sugar, overcoming the technical difficulty of manually obtaining samples from hard crystalline layers using a sampling spoon, significantly improving sampling efficiency and feasibility. The continuous drilling capability of the drill rod allows it to penetrate deep into the sugar paste. The device obtains samples at different depths internally, improving the representativeness of the samples and the accuracy of the test data, which helps to more accurately reflect the crystallization state inside the tank. The telescopic belt, located at the bottom of the drill rod and consisting of a first support plate and a second support plate connected by a flexible material, can be deployed simultaneously as the drill rod advances, effectively catching sugar sample debris generated during drilling, preventing samples from falling or remaining, and ensuring the integrity and collectability of the samples. The entire sampling process is mechanically driven, eliminating the need for manual hand placement into the high-temperature, vacuum environment, reducing the risk of burns or inhalation of harmful vapors for operators, and improving operational safety. At the same time, the device can sample without stopping the machine or disrupting the vacuum environment inside the tank, reducing interference with the continuity of the crystallization process, helping to maintain a stable supersaturated state, and avoiding crystallization abnormalities or small crystals caused by frequent opening of the lid for sampling.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Reference Figure 1-5 A sampler for a sugar boiling crystallization tank includes a support plate 1, a support plate 3 at the bottom of the support plate 1, and a first cylinder 2 fixedly connected to one side of the top of the support plate 1 by bolts. The output shaft of the first cylinder 2 passes through the top of the support plate 1 and is fixedly connected to the support plate 3. Connecting plates 6 are slidably connected to both sides of the bottom of the support plate 3. A drive motor 7 is fixedly connected to one side of each of the two connecting plates 6 by bolts. A drill rod 8 is rotatably connected to the other side of each of the two connecting plates 6. One end of the drill rod 8 passes through the connecting plate 6 through a bearing sleeve and is connected to the output shaft of the drive motor 7. A second support plate 10 is fixedly connected to the bottom of each of the two connecting plates 6. A first support plate 9 is provided on one side of each of the two second support plates 10. A telescopic belt 12 is fixedly connected between the first support plate 9 and the second support plate 10. The telescopic belt 12 is located at the bottom of the drill rod 8.

[0023] Place the support plate 1 horizontally at the top opening of the sugar crystallization tank, aligning it with the upper edge of the tank and sealing it tightly. Simultaneously, insert the support plate 3, fixed to the bottom of the support plate 1, vertically into the sugar crystallization tank. The support plate 3 serves as the supporting framework for the sampling structure, extending deep into the tank. Then, adjust the two connecting plates 6, which are slidably connected to the bottom sides of the support plate 3, to move them laterally along the support plate 3. This pushes the first support plate 9, fixed on one side, tightly against the inner wall of the sugar crystallization tank, achieving positioning and fixing of the sampler inside the tank and preventing shaking or displacement during subsequent operations. After positioning, start the two drive motors 7, bolted to the connecting plates 6. The output shafts of the drive motors 7 are connected to the drill rod 8 via bearing sleeves, driving the drill rod 8 to rotate at high speed. This drills and cuts the crystallized sugar paste or hard candy layer inside the tank. During rotation, the drill rod 8 continuously cuts into the sugar crystals, achieving deep penetration. Penetrating sampling: As the connecting plate 6 continues to advance along the support plate 3, the drill rod 8 simultaneously penetrates deeper, continuously pushing the broken sugar sample fragments onto the telescopic belt 12 set at its bottom. The telescopic belt 12 is formed by a flexible connection between the first support plate 9 and the second support plate 10, and can unfold synchronously with the feed action of the drill rod 8 to form a flexible tray for receiving and collecting samples, effectively preventing samples from scattering or adhering to the inside of the equipment. After sampling to the predetermined depth is completed, the drive motor 7 is turned off, and the connecting plate 6 is moved in the opposite direction to make the drill rod 8 exit the crystallization layer. Then, the entire bearing plate 1, together with the support plate 3 and the sampling components connected to it, is vertically extracted from the top of the sugar boiling crystallization tank. After being taken out, the sugar sample on the telescopic belt 12 can be collected for subsequent saturation, purity, or crystal analysis. The entire process does not require personnel to directly contact the high temperature and high viscosity environment, realizing a safe, efficient, and representative sampling operation.

[0024] Furthermore, several elastic rods 11 are fixedly connected to one side of each of the two first support plates 9, and one end of each elastic rod 11 is fixedly connected to one side of each of the two second support plates 10. During the process of the connecting plate 6 driving the first support plate 9 and the second support plate 10 to move towards and fit against the inner wall of the tank, the elastic rods 11 undergo elastic deformation, providing buffering and pre-tightening force, so that the first support plate 9 can fit more tightly and evenly against the inner wall surface of the tank with different diameters or slightly uneven surfaces, enhancing the stability of the sampler in the tank. At the same time, when the equipment is disassembled, the elastic rods 11 return to their original shape, which facilitates quick separation, thereby improving the flexibility, adaptability and reliability of the structural connection.

[0025] Furthermore, electric sliders 4 are fixedly connected to the top of both connecting plates 6, and both electric sliders 4 are slidably connected to the support plate 3 through the slide groove 5. The automatic sliding of the electric sliders 4 in the slide groove 5 realizes the precise and stable movement of the connecting plate 6 along the support plate 3, replacing manual pushing or manual adjustment. This improves the control accuracy and operation convenience of the transverse feed of the connecting plate 6, ensuring that the drill rod 8 can cut into the sugar crystal layer at a uniform speed and stably, avoiding equipment vibration or inconsistent sampling depth caused by uneven manual operation force. At the same time, it facilitates the realization of automated control, achieving the effect of improving the automation level of feed motion and the stability of operation.

[0026] Furthermore, telescopic rods 13 are fixedly connected to both sides of the top of the support plate 3, and the top ends of the two telescopic rods 13 are fixedly connected to the bottom of the bearing plate 1. The telescopic rods 13 work together with the first cylinder 2 to provide auxiliary guidance and structural support when the first cylinder 2 drives the support plate 3 to move up and down, preventing the support plate 3 from swaying or twisting during insertion or withdrawal, enhancing the rigidity and centering of the overall structure, absorbing some vibration stress, protecting the transmission components, and ensuring the reliability of the sampler during repeated lifting and lowering in high-temperature environments, thus achieving the effect of enhancing lifting stability and structural durability.

[0027] Furthermore, both sides of the bottom of the support plate 1 are provided with arc-shaped plates 15, and the top of each of the two arc-shaped plates 15 is fixedly connected with a sliding block 14. The two sliding blocks 14 are slidably connected to the support plate 1 through a sliding groove 17. The arc-shaped plates 15 are used to clamp the outer wall of the sugar boiling crystallization tank to improve the stability of the support plate 1. The curvature of the arc-shaped plates 15 matches the top outer wall of the sugar boiling crystallization tank. When the sliding block 14 slides in the sliding groove 17, it drives the arc-shaped plates 15 to move towards the tank body, thereby clamping and fixing the upper outer wall of the tank body. This firmly anchors the support plate 1 at the tank opening, preventing the support plate 1 from shifting or loosening due to internal resistance or vibration during the sampling process. This improves the overall installation stability and safety of the equipment and achieves the effect of enhancing external support and preventing loosening.

[0028] Furthermore, two second cylinders 16 are fixedly connected to both sides of the support plate 1, and the output shafts of the two second cylinders 16 pass through one side of the support plate 1. One end of the output shaft of the two second cylinders 16 is fixedly connected to one side of the two sliding blocks 14 respectively. After the second cylinders 16 are started, their output shafts push the sliding blocks 14 to slide in the sliding groove 17, thereby driving the arc plate 15 to move automatically towards the tank and clamp its outer wall. This realizes the mechanization and automation control of the clamping action, eliminating the need for manual locking and improving the efficiency of equipment installation and disassembly. At the same time, the clamping force can be precisely controlled to avoid damage to the tank due to excessive tightness or detachment due to excessive looseness, thus achieving the effect of improving the automation level and clamping reliability of the clamping operation.

[0029] In summary:

[0030] The support plate 1 is placed at the top opening of the sugar boiling crystallization tank, aligning it with the upper edge of the tank and ensuring a tight fit. The output shaft of the second cylinder 16, fixedly connected to both sides of the support plate 1, drives the sliding block 14 to slide within the sliding groove 17 of the support plate 1. This causes the arc-shaped plate 15, fixed to the top of the sliding block 14, to move towards the outer wall of the tank. The curved surface structure of the arc-shaped plate 15 automatically clamps the outer wall of the sugar boiling crystallization tank, firmly fixing the support plate 1 at the tank opening and preventing displacement during sampling. Simultaneously, the first cylinder 2, bolted to the bottom of the support plate 1, is activated, and its output shaft... The support plate 3 is pushed downwards and vertically inserted into the sugar crystallization tank. Telescopic rods 13 are also provided on both sides of the top of the support plate 3, with their ends connecting the bottom of the bearing plate 1 and the top of the support plate 3 respectively. These rods, along with the first cylinder 2, provide guidance and structural support, ensuring the support plate 3 remains vertically stable during lifting and lowering, preventing swaying or jamming. After the support plate 3 is inserted into place, the connecting plates 6, which are slidably connected on both sides of its bottom, move smoothly laterally along the grooves 5 on the support plate 3 under the drive of the electric slider 4. The electric slider 4 is electrically driven, enabling precise feed control of the connecting plates 6. As the connecting plates 6 move, the fixed drive on one side... The drive motor 7 advances synchronously, and the output shaft of the drive motor 7 is connected to the drill rod 8 through a bearing sleeve, driving the drill rod 8 to rotate at high speed to drill and cut the crystallized sugar paste or hard sugar layer inside the tank. The second support plate 10 fixed on the other side of the connecting plate 6 is connected to the first support plate 9 by a telescopic belt 12, and several elastic rods 11 are also provided between them. During the advancement of the connecting plate 6, the first support plate 9 contacts and fits against the inner wall of the tank. The elastic rods 11 are compressed and generate elastic deformation, providing buffering and adaptive pre-tightening force, so that the first support plate 9 can fit tightly against the tank wall of different diameters or unevenness, enhancing the equipment's stability inside the tank. The lateral stability is ensured; while the drill rod 8 is rotating and drilling, it pushes the broken sugar sample chips onto the telescopic belt 12 below it. The telescopic belt 12 gradually unfolds as the drill rod 8 goes deeper, forming a continuous sample receiving surface, effectively collecting the drilled crystal sample and preventing it from scattering. After sampling is completed, the drive motor 7 stops, the electric slider 4 drives the connecting plate 6 to retract, the drill rod 8 exits the crystal layer, the second cylinder 16 reverses its action to loosen the arc plate 15 from the tank, the first cylinder 2 retracts and drives the support plate 3 and the entire sampling assembly to be vertically extracted from the tank. Then the sample on the telescopic belt 12 can be collected and taken out for analysis.

[0031] The sampler, through the cooperation of the support plate 1, the second cylinder 16, the sliding block 14, the sliding groove 17, and the arc plate 15, achieves automatic clamping and positioning of the equipment at the top of the sugar crystallization tank, improving the stability of the installation and the convenience of operation, and avoiding the unreliability of traditional manual fixing methods. The first cylinder 2 drives the support plate 3 to move up and down, and combined with the auxiliary guidance and structural reinforcement provided by the telescopic rod 13, it ensures that the sampling component can be smoothly and vertically inserted and withdrawn from the high-temperature sealed crystallization tank, improving the reliability and safety of the lifting process. The support plate 3, as the main support structure, provides a stable platform for the subsequent lateral sampling mechanism. The connecting plate 6 slides in the sliding groove 5 through the electric slider 4, realizing the automation and precise control of the lateral feed, replacing manual adjustment, and improving the consistency and controllability of the drill rod 8's cutting depth. The drive motor 7 drives the drill rod 8. The rotating, mechanical drilling method effectively solves the technical challenge of manually sampling from hard crystalline sugar layers, significantly improving sampling efficiency and feasibility. The drill rod 8 penetrates deep into the sugar crystals for penetrating sampling, resulting in more representative samples that help accurately determine the crystallization process. The telescopic belt 12, located at the bottom of the drill rod 8, is flexibly connected by the first support plate 9 and the second support plate 10, and maintains structural stability under the buffering effect of the elastic rod 11. It can be deployed synchronously during drilling to completely receive the sugar sample generated during drilling, preventing sample loss or contamination. The entire sampling process does not require personnel to directly contact the dangerous environment of high temperature, high viscosity, and vacuum, greatly reducing safety risks such as burns and steam inhalation. The equipment can complete sampling without stopping the machine, reducing interference with the vacuum level inside the tank and the stability of the crystallization process, which is conducive to maintaining a continuous and high-quality crystallization process.
