Description

Technical Field

[0001] This utility model relates to the field of spiral sampler technology, specifically a spiral sampler for sampling wheat soaking tanks. Background Technology

[0002] As is well known, the maceration process is a crucial step in beer brewing and barley processing. The collection of liquid samples from the maceration tank is essential for monitoring and ensuring the quality of the final product. However, different production processes require maceration tanks with varying sizes, water levels, and depths. Traditional samplers, due to their fixed design, struggle to adapt to these diverse needs. This means that different sampling equipment must be used for different maceration tank sizes, increasing operational complexity and time costs. Traditional samplers typically rely on manual operation, which is not only labor-intensive but also particularly difficult and inaccurate when collecting samples at high water levels or deep depths. Furthermore, manual operation can lead to sample contamination, affecting the accuracy of subsequent analysis results. To address these challenges, companies often need to purchase and maintain various sizes of sampling equipment to meet different needs, increasing initial investment costs and incurring long-term maintenance and management burdens. Because traditional samplers struggle to precisely control the sampling location, especially the depth, the obtained samples may not fully represent the actual conditions within the maceration tank, thus affecting the effectiveness of quality control. Therefore, it is necessary to propose solutions to this technical problem. Utility Model Content

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a spiral sampler for sampling wheat soaking tanks, which has the following beneficial effects:

[0016] This spiral sampler for wheat soaking tank sampling uses a water level sensor to accurately detect the water level in the soaking tank, ensuring the sampling port is at the optimal height for sampling. This not only improves sample representativeness but also provides reliable data support for subsequent quality control. An electric slider allows the spiral sampler to move linearly along a slide rail, flexibly adjusting its horizontal position. This enables the equipment to be quickly and accurately positioned anywhere above the soaking tank, greatly improving operational flexibility and efficiency. Through the cooperation of an electromagnet with a lifting column and lifting cylinder, the spiral sampler's position can be firmly fixed after adjustment, maintaining stability even during vibrations caused by the spiral mechanism's operation. This not only enhances equipment stability but also reduces wear on components caused by vibration, extending its service life. From moving to the designated position, adjusting the sampling depth, executing the sampling task, to finally retrieving the sample, the entire process is automated, significantly improving work efficiency, reducing errors that may be caused by human operation, and enhancing sampling accuracy and consistency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model relates to a spiral sampler for sampling wheat soaking ponds, comprising a spiral sampler 1 and an installation platform 2. The spiral sampler 1 is provided with a sampling port 3, a spiral mechanism, a water level sensor 4, and a sample storage mechanism. The sampling port 3 is provided with a sealing mechanism. The bottom end of the installation platform 2 is provided with a sliding groove, and a sliding rail 5 is provided on the sliding groove. An electric slider 6 is provided on the sliding rail 5. The bottom end of the electric slider 6 is provided with an adjusting plate 7. A lifting mechanism 8 is provided between the adjusting plate 7 and the top end of the spiral sampler 1. The spiral sampler 1 is provided with an installation plate 9, and a locking mechanism is provided between the installation plate 9 and the adjusting plate 7. The locking mechanism includes a lifting iron cylinder 10 and a lifting column 11. The lifting column 11 is installed on the... The lifting cylinder 10 is installed at the bottom of the adjusting plate 7, with a lifting hole at the bottom of the lifting cylinder 10. The lifting column 11 extends into the lifting hole, and an electromagnet 12 is provided on one side of the lifting column 11. The electromagnet 12 is embedded in the lifting column 11. In this embodiment, the installation platform 2 is assembled and installed with existing transport and mobile equipment, such as on a transport trolley. Common parts such as brackets are used to install and fix the installation platform 2. Then, the installation platform 2 is moved above the soaking tank by the transport trolley. By controlling the electric slider 6 to move linearly on the slide rail 5 of the chute, the position of the spiral sampler 1 can be flexibly adjusted, making it convenient to place the spiral sampler 1. The spiral sampler 1 is moved above the soaking tank and then lowered using the lifting mechanism 8. The spiral sampler 1 enters the soaking tank, and the water level sensor 4 detects the water level of the spiral sampler 1 within the tank, thus determining the height of the sampling port 3. This allows for high-precision adjustment of the sampling water level. During the lifting and lowering movement, the spiral sampler 1 drives the lifting column 11 in the locking mechanism to move linearly up and down through the lifting hole in the lifting cylinder 10, improving the smoothness of the spiral sampler 1's movement. After reaching the designated position, the electromagnet 12 embedded on one side of the lifting column 11 is activated. The electromagnet 12 is then firmly and reliably attracted to the inner wall of the lifting cylinder 10 through the lifting hole, thus securely fixing the spiral sampler. At position 1, during sampling, the sealing mechanism is first used to release the seal, exposing the sampling port 3 to the soaking tank. Then, the liquid in the soaking tank is passed through the spiral sampler 1 into the sample storage mechanism for storage via the spiral mechanism. Even with swaying during spiral operation, the working force attracted by the electromagnet 12 ensures that the spiral sampler 1 remains stably and reliably fixed in position, reducing the impact of swaying forces on the lifting mechanism 8 and thus affecting its service life. After sampling, the spiral mechanism is closed, and then the electromagnet 12 is turned off, controlling the lifting mechanism 8 to retract and move, thereby lifting the spiral sampler 1 out of the water surface for easy sample retrieval using the sample storage mechanism. This structure is fully automated throughout the entire sampling process in the soaking tank.Furthermore, the water level sensor 4 detects the water level to calculate the height of the sampling port 3 in the wheat soaking tank, enabling more precise sampling. The sliding rail 5 and slider work together to automatically move the spiral sampler 1 above the wheat soaking tank, facilitating entry for sampling.

[0024] The sealing mechanism described above can be any type of sealing device. In order to facilitate sealing the sampling port 3, in this solution, the sealing mechanism includes a telescopic mechanism 13 and a sealing arc plate 14. The telescopic mechanism 13 is installed at the bottom end of the mounting plate 9. A connecting plate is provided between the output end of the telescopic mechanism 13 and the sealing arc plate 14. The sealing arc plate 14 abuts against the side of the spiral sampler 1 and is located above the sampling port 3. By controlling the output end of the telescopic mechanism 13 to move the connecting plate linearly, the connecting plate drives the sealing arc plate 14 to seal or move away from the sampling port 3, thereby realizing automatic control of the sealing state of the sampling port 3.

[0025] The above-mentioned sample storage mechanism can be any type of sample storage device. In order to facilitate sample storage, in this solution, the sample storage mechanism includes a sample storage box 15. A connecting pipe is provided between the sample storage box 15 and the spiral sampler 1. A drain pipe 16 is provided on one side of the sample storage box 15. Both the drain pipe 16 and the connecting pipe are equipped with electric valves 17. By opening the electric valve 17 on the connecting pipe, the sample transported by the spiral mechanism can enter the sample storage box 15 through the connecting pipe for storage. Then, the electric valve 17 on the connecting pipe is closed, thereby sealing the sample in the sample storage box 15. When it is necessary to remove the sample, the sample can be discharged through the drain pipe 16 by opening the electric valve 17 on the drain pipe 16.

[0026] To facilitate sampling through sampling port 3, in this design, the spiral mechanism includes a drive motor 18 and a spiral shaft 19. The drive motor 18 is installed at the top of the spiral sampler 1, and the spiral shaft 19 is located inside the spiral sampler 1. The output end of the drive motor 18 is connected to the spiral shaft 19. By controlling the output end of the drive motor 18 to rotate the spiral shaft 19, the spiral shaft 19 can transport the liquid near the sampling port 3 into the spiral sampler 1 through the spiral, thereby facilitating the sampling operation.

[0027] To further improve the rotational stability of the spiral shaft 19, in this design, a bearing seat 20 is provided between the spiral shaft 19 and the inner bottom end of the spiral sampler 1. The bearing seat 20 can improve the stability of the spiral shaft 19 during rotation.

[0028] In order to further securely and reliably lock the height position of the spiral sampler 1, in this solution, multiple locking mechanisms are provided and symmetrically arranged. The lifting iron cylinder 10 is attracted by the electromagnets 12 in two locking mechanisms, which can further improve the fixing reliability of the spiral sampler 1.

[0029] The lifting mechanism 8 and the telescopic mechanism 13 mentioned above can be any type of telescopic device. In order to further improve the control accuracy and stability, in this solution, the lifting mechanism 8 and the telescopic mechanism 13 are both electric telescopic rods. By using electric telescopic rods, electric telescopic rods have the characteristics of high movement accuracy and good stability, thereby improving the control accuracy and stability.

[0030] To improve waterproof performance, in this design, the drive motor 18 is a brushless DC motor. Brushless DC motors have the characteristic of good sealing, thus making them suitable for sampling operations in wheat soaking tanks.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
