Description

Technical Field

[0001] This utility model relates to the field of chemical reagents and auxiliaries, specifically a chemical reagent and auxiliary sampling device. Background Technology

[0002] Chemical reagents and auxiliaries are a class of auxiliary chemicals used in chemical experiments, industrial production, and other applications. They are mainly used to promote chemical reactions, improve process conditions, or enhance product performance. Depending on their function, they can be divided into various types such as catalysts, solvents, and surfactants, and are widely used in fields such as medicine, new materials, and electronics.

[0003] However, current sampling methods for chemical reagents and auxiliaries are difficult to quantify and rely on manual operation, which can easily lead to inaccurate sampling amounts. Furthermore, the sampling process requires frequent manual placement of the sample collection tube, which reduces sampling efficiency. To address these issues, we propose a chemical reagent and auxiliary sampling device. Utility Model Content

[0012] The sampling mechanism enables automatic quantitative sampling of chemical reagents and auxiliaries without manual operation, avoiding the sampling deviations that are prone to occur with manual sampling. This provides a reliable sample basis for subsequent analysis or production testing. The geared motor drives the second gear to rotate, which in turn drives the first gear, rotating rod, and turntable to rotate.

[0019] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0020] According to one embodiment of the present invention, in conjunction with the appendix Figure 1-4 As shown.

[0021] A chemical reagent and auxiliary agent sampling device includes a platform 1, a carrier plate 2 fixedly mounted on the upper surface of the platform 1, a photoelectric sensor 3 fixedly mounted on the right side of the carrier plate 2, a sampling mechanism 4 above the carrier plate 2, a bearing 5 fixedly embedded on the upper surface of the platform 1, a rotating rod 6 fixedly connected to the inner ring of the bearing 5, a first gear 7 fixedly connected to the bottom end of the rotating rod 6, a reduction motor 8 mounted on the bottom surface of the platform 1, a second gear 9 fixedly connected to the output end of the reduction motor 8, the first gear 7 and the second gear 9 meshing, a turntable 10 fixedly mounted on the top end of the rotating rod 6, four limiting cylinders 11 fixedly mounted on the upper surface of the turntable 10, two sets of springs 12 fixedly connected to the inner walls of each of the four limiting cylinders 11, eight arc-shaped plates 13 fixedly connected to the ends of the eight sets of springs 12 that are close to each other, and four sample collection cylinders 14 placed on the upper surface of the platform 1, the sides of the eight arc-shaped plates 13 that are close to each other respectively connecting to the four sampling cylinders 14. The outer surfaces of the sample collection tubes 14 are in contact. Through the sampling mechanism 4, chemical reagents and auxiliaries can be automatically and quantitatively sampled without manual operation, avoiding the sampling deviation that is prone to occur in manual sampling. This provides a reliable sample basis for subsequent analysis or production testing. The geared motor 8 drives the second gear 9 to rotate, which in turn drives the first gear 7, the rotating rod 6, and the turntable 10 to rotate. In cooperation with the photoelectric sensor 3, the rotation and positioning of the next sample collection tube 14 can be completed automatically after one sample collection tube 14 is filled. This eliminates the need for frequent manual placement and replacement of sample collection tubes 14, reduces operation interruption time, and improves overall sampling efficiency. In addition, the setting of eight sets of springs 12 and eight arc plates 13 can tightly fix the sample collection tubes 14 through elastic force, avoiding reagent leakage caused by shaking of the sample collection tubes 14 during sampling, and reducing the risk of pollution to the sampling environment.

[0022] In this embodiment, the sampling mechanism 4 includes a metering pump 401. The outer surface of the metering pump 401 is fixedly installed on the upper surface of the carrier plate 2. The input end of the metering pump 401 is fixedly connected to a sampling tube 402, and the output end of the metering pump 401 is fixedly connected to a discharge tube 405. The outer surface of the sampling tube 402 is fixedly connected to a one-way valve 403, and the left end of the sampling tube 402 is fixedly connected to a sampling head 404. By utilizing the setup of the sampling mechanism 4, the metering pump 401 can be started to work. Chemical reagents and auxiliaries can be extracted through the sampling head 404 at the left end of the sampling tube 402. At the same time, the one-way valve 403 on the sampling tube 402 ensures that the reagent flows in one direction and prevents backflow, so that the extracted chemical reagents and auxiliaries are discharged through the discharge tube 405. The metering pump 401 precisely controls the sampling amount according to the set parameters to achieve quantitative sampling.

[0023] In this embodiment, a PLC controller 15 is fixedly installed on the front of the platform 1, and two support plates 16 are fixedly connected to the bottom of the platform 1. A protective cover 17 is installed on the bottom of the platform 1, and a dustproof net 18 is fixedly embedded on the bottom of the protective cover 17. Through the setting of the PLC controller 15, the device can be automatically controlled. By using the protective cover 17 and the dustproof net 18, the internal components can be protected and ventilated to prevent dust.

[0024] Working principle: First, install the device in the designated position and connect it to the power supply. Then, place the four sample collection cylinders 14 into the four limiting cylinders 11 on the turntable 10. The elastic force of the eight sets of springs 12 on the inner wall of the four limiting cylinders 11 is used to drive the eight arc plates 13 to tightly fit the outer surface of the four sample collection cylinders 14, so as to stabilize and fix the four sample collection cylinders 14 and prevent shaking. At the same time, the sampling parameters are set by the PLC controller 15. Then, the quantitative pump 401 is started to extract chemical reagents and auxiliaries through the sampling head 404 at the left end of the sampling tube 402. At the same time, the one-way valve 403 on the sampling tube 402 ensures that the reagents flow in one direction and prevents backflow. The extracted chemical reagents and auxiliaries are quantitatively discharged into the sample collection cylinders 14 below through the discharge tube 405.

[0025] Once a sample collection cylinder 14 has finished collecting samples, the geared motor 8 is started to drive the second gear 9 to rotate, which in turn drives the first gear 7, the rotating rod 6, and the turntable 10 to rotate. At the same time, the photoelectric sensor 3 detects that the next sample collection cylinder 14 has reached the designated position and sends a signal back to the PLC controller 15. The PLC controller 15 then controls the geared motor 8 to stop working and automatically positions the sample collection cylinder 14 for the next sampling. This process is repeated until all four sample collection cylinders 14 have completed sampling.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
