Detailed Implementation

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figures 1 to 4 As shown in the figure, a sampling and detection device for the preparation of biodegradable geminal quaternary ammonium salt according to an embodiment of the present invention includes a preparation container 1; a fixing frame 11 is fixedly connected to the outer wall of the preparation container 1; a sampling component is provided on the outer wall of the preparation container 1; a shock-absorbing component is provided on the top of the fixing frame 11; a heat-insulating component is provided on the preparation container 1 through the sampling component; and a sample support component is provided at the bottom of the fixing frame 11. During operation, the reaction solution reacts inside the preparation container 1. The sampling component extracts the reaction solution from inside the preparation container 1 and returns it to the preparation container 1 through a pipe. When sampling is required, the sampling component circulates the liquid during the extraction process. The bypass valve of the sampling component is opened for sampling. The sampling container is placed on the sample support component for sampling. The heat preservation component keeps the extracted solution warm, and the shock absorption component buffers and reduces shock for the sampling component. Finally, the product yield of the sampled solution is detected. This step, through the setup of container 1, fixing frame 11, sampling component, shock absorption component, heat preservation component, and sample support component, forms the sampling structure in the preparation process of ester-type geminal quaternary ammonium salt. It realizes the function of sampling and detection without stopping the reaction device, reduces the problem of increased reaction time due to sampling, and simplifies the sampling and detection operation steps.

[0025] like Figure 1 and Figure 2As shown, the sampling assembly includes a suction tube 12, a first ball valve 13, a peristaltic pump 14, a second ball valve 15, a sampling port 16, and a return tube 17. The suction tube 12 is fixedly connected to the side wall of the preparation container 1. Multiple sets of suction tubes 12 are arranged on the side wall of the preparation container 1. The first ball valve 13 is fixedly connected to the end of the suction tube 12 away from the preparation container 1. The peristaltic pump 14 is mounted on the side wall of the mounting frame 11 through a shock-absorbing assembly. The ends of the multiple sets of first ball valves 13 away from the suction tube 12 are connected to the return tube 17 through the peristaltic pump 14. The return tube 17 is inserted into the side wall of the preparation container 1 away from the suction tube 12. The internal pipe of the peristaltic pump 14 is a flexible tube. The second ball valve 15 is fixedly connected to the bottom of the return tube 17 near the peristaltic pump 14. The sampling port 16 is fixedly connected to the bottom of the second ball valve 15. During operation, different first ball valves 13 are opened according to the sampling location to start the peristaltic pump 14. The reaction solution is drawn into the sampling assembly through the suction tube 12 and then pumped back into the preparation container 1 through the return tube 17. During sampling, the second ball valve 15 is opened, and the reaction solution flows out from the sampling port 16 and is collected by the sampling container. After sampling, the second ball valve 15 is closed, while at least one first ball valve 13 remains open. The peristaltic pump 14 remains running, allowing the reaction solution to circulate within the sampling assembly. This step, through the arrangement of the suction tube 12, the first ball valve 13, the peristaltic pump 14, the second ball valve 15, the sampling port 16, and the return tube 17, forms a cyclic sampling structure at different points. This enables sampling at different points without stopping the reaction device, solving the problem of needing to stop the reaction device during sampling, improving the accuracy of sampling and detection data, simplifying the sampling and detection steps, and providing convenience for sampling and detecting the reaction solution.

[0026] like Figure 1 and Figure 4As shown, the sample support assembly includes a support frame 2, a placement plate 21, a sponge block 22, and a handle 23. The support frame 2 is fixedly connected to the bottom of the fixing frame 11 near the sampling port 16. The end of the placement plate 21 is rotatably connected to the middle of the support frame 2. The sponge block 22 is fixedly connected to the top of the placement plate 21. A pair of sponge blocks 22 are provided on the top of the placement plate 21 and are arranged symmetrically. The handle 23 is fixedly connected to the end of the placement plate 21 away from the support frame 2. A collection assembly is provided on the top of the support frame 2 away from the preparation container 1. During operation, when sampling, the handle 23 is held and the placement plate 21 is rotated so that the placement plate 21 faces the sampling port 16, and the sampling container is placed on the placement plate 21. Between the sponge blocks 22 on the top of the plate 21, the sponge blocks 22 clamp and fix the outer wall of the container. The sampling port 16 is opened for sampling. After sampling, the sampled solution is removed. The handle 23 is turned to move the sponge blocks 22 away from the sampling port 16. The reaction solution dripping from the sampling port 16 is collected by the collection component. This step, through the setting of the support frame 2, the placement plate 21, the sponge blocks 22 and the handle 23, forms a sampling container fixing structure, realizes the function of fixing the sampling container during sampling, solves the problem of the sampling container tipping over during sampling, improves the stability of the sampling container during sampling, and reduces the situation of reaction solution overflow causing contamination of other items.

[0027] like Figure 2 and Figure 3 As shown, the shock absorption assembly includes a fixed plate 3, an airbag 31, and a motor frame 32. The motor frame 32 is fixedly connected to the outer wall of the peristaltic pump 14. The fixed plate 3 is fixedly connected to the top of the fixed frame 11 near the peristaltic pump 14. The airbag 31 is fixedly connected to the bottom of the motor frame 32. The bottom of the airbag 31 is fixedly connected to the top of the fixed plate 3. Multiple sets of airbags 31 are set at the bottom of the motor frame 32 and are evenly distributed at the bottom of the motor frame 32. During operation, the fixed plate 3, the airbag 31, and the motor frame 32 fix the peristaltic pump 14 to the outside of the preparation container 1. The vibration generated by the peristaltic pump 14 during operation is transmitted to the airbag 31, and the airbag 31 weakens the vibration transmitted by the peristaltic pump 14. This step, through the arrangement of the fixed plate 3, the airbag 31, and the motor frame 32, forms a shock absorption and buffering structure for the peristaltic pump 14, realizing the function of shock absorption and buffering for the peristaltic pump 14, solving the problem of vibration during operation of the peristaltic pump 14, improving the stability of the peristaltic pump 14 during operation, and reducing the possibility of loosening of pipe connections due to vibration of the peristaltic pump 14.

[0028] like Figure 1 and Figure 2As shown, the insulation component includes insulation cotton 4 and heating tube 41; the insulation cotton 4 is sleeved on the outer wall of the return pipe 17 near the second ball valve 15; the heating tube 41 is wrapped around the outer wall of the return pipe 17 near the preparation container 1; during operation, after the reaction solution is drawn out by the peristaltic pump 14, it enters the preparation container 1 through the return pipe 17. The insulation cotton 4 insulates the middle part of the return pipe 17. When the solution temperature is low, the heating tube 41 is connected to a circulating hot water device to heat the solution entering the preparation container 1. This step, through the setting of insulation cotton 4 and heating tube 41, forms a reaction solution insulation and heating structure, realizing the control of the reaction solution temperature in the return pipe 17, increasing the temperature when the reaction solution flows back into the preparation container 1, and reducing the situation where the reaction rate inside the preparation container 1 decreases due to temperature loss.

[0029] like Figure 1 As shown, a foot plate 5 is fixedly connected to the bottom of the fixed frame 11; multiple sets of foot plates 5 are set at the bottom of the fixed frame 11; during operation, when the fixed frame 11 supports the preparation container 1, the foot plate 5 increases the contact area between the fixed frame 11 and the ground; this step, through the setting of the foot plate 5, forms a support and fixing structure for the fixed frame 11, reducing the problem of the preparation container 1 tipping over during operation and improving the stability of the preparation container 1 when placed.

[0030] like Figure 1 and Figure 4 As shown, the collection component includes a collection box 6; the collection box 6 is fixedly connected to the top of the support frame 2 away from the preparation container 1; during operation, after the placement plate 21 is removed, the collection box 6 is located at the bottom of the sampling port 16, and the residual solution in the sampling port 16 drips down and is collected by the collection box 6; this step, through the setting of the collection box 6, forms a residual solution collection structure, improves the convenience of collecting residual solution, and reduces the possibility of residual solution dripping onto other items and causing damage.

[0031] During operation, the reaction solution reacts inside preparation container 1. The sampling component extracts the reaction solution from preparation container 1 and returns it to preparation container 1 through a pipeline. When sampling is required, the bypass valve of the sampling component is opened during the circulation extraction process. The sampling container is placed on the sample support component for sampling. The heat preservation component keeps the extracted solution warm, and the shock absorption component buffers and dampens the sampling component. Finally, the product yield is tested on the sampled solution. Different first ball valves 1 are opened according to the sampling location. 3. Start the peristaltic pump 14. The reaction solution is drawn into the sampling assembly through the suction tube 12 and then pumped back into the preparation container 1 through the return tube 17. During sampling, open the second ball valve 15, and the reaction solution flows out from the sampling port 16 and is collected using the sampling container. After sampling, close the second ball valve 15, keeping at least one first ball valve 13 open. Keep the peristaltic pump 14 running to circulate the reaction solution within the sampling assembly. During sampling, hold the handle 23 and rotate the placement plate 21 so that the placement plate 21 faces the sampling container. Sampling port 16 is used to place the sampling container between the sponge blocks 22 on top of the placement plate 21. The sponge blocks 22 clamp and fix the outer wall of the container. Sampling port 16 is opened for sampling. After sampling, the sampled solution is removed. The handle 23 is turned to move the sponge blocks 22 away from the sampling port 16. The reaction solution dripping from the sampling port 16 is collected by the collection component. The fixing plate 3, air bag 31 and motor frame 32 fix the peristaltic pump 14 to the outside of the preparation container 1. The vibration generated by the peristaltic pump 14 when it is working is transmitted to the air bag 31. The air bag 31 transmits the vibration of the peristaltic pump 14 to the air bag 31. The vibration is reduced; after the reaction solution is drawn out by the peristaltic pump 14, it enters the preparation container 1 through the return pipe 17. The insulation cotton 4 keeps the middle of the return pipe 17 warm. When the solution temperature is low, the heating pipe 41 is connected to the circulating hot water equipment to heat the solution entering the preparation container 1; when the fixing frame 11 supports the preparation container 1, the foot plate 5 increases the contact area between the fixing frame 11 and the ground; after the placement plate 21 is removed, the collection box 6 is located at the bottom of the sampling port 16. The solution remaining in the sampling port 16 drips down and is collected by the collection box 6.
