Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a sampler for a reaction vessel. Background Technology

[0002] A reaction vessel is a container used for physical or chemical reactions. In order to understand the chemical reaction process or the material mixing process inside the reaction vessel, it is often necessary to take samples of the materials inside the reaction vessel for testing at different stages.

[0003] A Chinese patent with publication number CN218167005U discloses a sampler for a polyurethane reactor that facilitates sampling. The sampler includes: a motor, an addition port, a conduit, a reaction chamber, a sampling tube, a rotating shaft, a spiral blade, a stirring blade, a suction tube, a discharge port, a discharge tube, a glue head, and a base. The reaction chamber is located at the lower end of the motor, and the addition port is located at the upper end of the reaction chamber. A conduit is installed on the upper left side of the reaction chamber, and a sampling tube is installed on the right side of the middle position of the reaction chamber. A glue head is installed at the upper end of the sampling tube, and a base is installed at the lower end of the reaction chamber. Compared with the prior art, this invention has the following advantages: by using the spiral blade and stirring blade, the polyurethane can be reacted quickly, thereby ensuring sample quality; by using the glue head and sampling tube, the sample can be taken without contact with the sample.

[0004] The sampler for the aforementioned reactor can only sample from a single location, making it impossible to accurately obtain samples at different depths. Sampling from a single location only reflects the situation in that local area and cannot fully reflect the true state of the materials inside the reactor, leading to misjudgments of the reaction process and making it difficult to accurately determine whether the reaction has reached the expected endpoint, thus affecting the quality of the final product. Therefore, a sampler for the reactor is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a sampler for a reaction vessel.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A sampler for a reaction vessel according to this utility model includes three support legs, which are fitted with a reaction vessel body. Two support blocks are fixed to the outer wall of the reaction vessel body. A pneumatic cylinder is mounted on each of the two support blocks. A pneumatic rod is fitted to the actuating end of each of the two pneumatic cylinders. A lifting plate is fixed to the top of each pneumatic rod. A sampling tube is fixed to the bottom side of the lifting plate, and the sampling tube penetrates the top of the reaction vessel body. Two L-shaped plates are fixed to the top side of the lifting plate. A cylinder is fixed between the two L-shaped plates. A piston is installed inside the cylinder. A movable rod is fixed to the piston. A push-pull plate is installed at the top of the movable rod. A guide pipe is connected between the cylinder and the sampling tube, and a valve is installed on the guide pipe. A liquid outlet pipe is connected to the bottom of the circumferential surface of the cylinder, and a first one-way valve is installed on the liquid outlet pipe. During sampling, two pneumatic cylinders are controlled synchronously by the control panel to move the lifting plate up or down the sampling tube until the sampling tube moves to the specified depth position. This enables precise sampling at different depth positions. By sampling at different depth positions, material samples from different areas inside the reactor can be obtained, which can more comprehensively reflect the true situation of the composition, concentration, temperature and other parameters of the material inside the entire reactor. This allows for more accurate assessment of the reaction progress, ensures precise control of reaction conditions, and improves product quality.

[0007] Preferably, a sealing plate is installed at the bottom port of the sampling tube via a rotating shaft, and a waterproof motor is installed on the outer wall of the sampling tube. The output end of the waterproof motor is connected to one end of the rotating shaft. When adjusting the sampling tube to different depths, the bottom port of the sampling tube is sealed by the sealing plate, which prevents the material from entering prematurely during the movement of the sampling tube, reduces errors caused by premature material entry, and ensures the accuracy of the sampling depth. When the sampling tube reaches the designated depth for sampling, the waterproof motor is started, causing the rotating shaft to drive the sealing plate to rotate from the original horizontal state to the vertical state, thereby opening the bottom port of the sampling tube. After the sampling tube reaches the target depth, the bottom port is opened again for sampling. This reduces the disturbance of the material during the sampling process, making the sample more accurately reflect the properties of the material at that depth.

[0008] Preferably, a protective cover is fixed to the outer circumference of the sampling tube, and the waterproof motor is installed inside the protective cover. When using the device, the protective cover provides physical protection for the waterproof motor, reducing the risk of damage. It also provides additional waterproof protection, reducing the possibility of water entering the motor and ensuring that the motor can work normally in humid environments such as underwater.

[0009] Preferably, an electric motor is installed on the top of the reactor body, and the output end of the electric motor is connected to a stirring shaft. Multiple stirring blades are fixed on the outer surface of the stirring shaft, and a U-shaped scraper is installed at the bottom end of the stirring shaft. When the chemical reaction is carried out, the electric motor is started, causing the stirring blades and the U-shaped scraper to rotate. Through the synergistic action of the stirring blades and the U-shaped scraper, the materials in the reactor body can be fully and uniformly mixed, thereby improving the efficiency of the polymerization reaction and the product quality.

[0010] Preferably, a feed pipe is connected to the top side of the reactor body, and a discharge pipe is connected to the bottom of the reactor body. A second one-way valve is installed on the discharge pipe. When using this device, the feed pipe facilitates the addition of materials into the reactor body, and the discharge pipe facilitates the removal of reaction products.

[0011] Preferably, the outer surface of the reactor body is provided with an observation window and a control panel from bottom to top. The control panel is used to control the start and stop of the pneumatic cylinder, waterproof motor and electric motor. When using the device, the operator can intuitively see the mixing status of the materials, color changes, and the state of the reactants by setting up the observation window. This is very important for judging the reaction progress and whether the reaction conditions need to be adjusted. By setting up the control panel, this centralized control method greatly improves the convenience of operation and reduces the time and labor intensity of the operator to walk back and forth between different equipment.

[0012] The advantages of this utility model are:

[0013] 1. Before sampling, this utility model controls two pneumatic cylinders to operate synchronously via a control panel, causing the lifting plate to move the sampling tube up or down until the sampling tube reaches the specified depth. This enables precise sampling at different depths. By sampling at different depths, material samples from different areas within the reactor can be obtained, providing a more comprehensive reflection of the composition, concentration, temperature, and other parameters of the materials within the entire reactor. This allows for a more accurate assessment of the reaction progress, ensuring precise control of reaction conditions and improving product quality.

[0014] 2. In this invention, when adjusting the sampling tube to different depth positions, the bottom port of the sampling tube is sealed by the sealing plate, which avoids the premature entry of material during the movement of the sampling tube, reduces the error caused by the premature entry of material, and ensures the accuracy of the sampling depth. When the sampling tube reaches the designated depth for sampling, the waterproof motor is started, causing the rotating shaft to drive the sealing plate to rotate from the original horizontal state to the vertical state, thereby opening the bottom port of the sampling tube. After the sampling tube reaches the target depth, the bottom port is opened again for sampling. This reduces the disturbance of material during the sampling process, so that the sample obtained can more accurately reflect the properties of the material at that depth.

[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 scope of protection of the present utility model.

[0023] Please see Figure 1-5As shown, a sampler for a reaction vessel includes three support legs 1, which are fitted with a reaction vessel body 2. Two support blocks 3 are fixed to the outer wall of the reaction vessel body 2. A pneumatic cylinder 4 is mounted on each of the two support blocks 3. A pneumatic rod 5 is fitted to the actuating end of each of the two pneumatic cylinders 4. A lifting plate 6 is fixed to the top of each of the two pneumatic rods 5. A sampling tube 7 is fixed to the bottom side of the lifting plate 6 and extends through the top of the reaction vessel body 2. Two L-shaped plates 8 are fixed to the top side of the lifting plate 6. A cylinder 9 is fixed between the two L-shaped plates 8. A piston 10 is installed inside the cylinder 9. A movable rod 11 is fixed to the piston 10. A push-pull plate 12 is installed at the top of the movable rod 11. A guide pipe 13 connects the cylinder 9 and the sampling tube 7. A valve is installed on the cylinder 13, and a liquid outlet pipe 14 is connected to the bottom of the circumferential surface of the cylinder 9. A first one-way valve is installed on the liquid outlet pipe 14. During operation, before sampling, the two pneumatic cylinders 4 are controlled to work synchronously through the control panel 26, so that the two pneumatic rods 5 drive the lifting plate 6 to move up or down, thereby moving the sampling tube 7 accordingly. When the sampling tube 7 moves to the specified depth position, the pneumatic cylinder 4 stops working, thus enabling precise sampling at different depth positions. By sampling at different depth positions, material samples from different areas inside the reactor can be obtained, which can more comprehensively reflect the true situation of the composition, concentration, temperature and other parameters of the material inside the entire reactor, thereby more accurately assessing the reaction progress, ensuring precise control of reaction conditions, and improving product quality.

[0024] The bottom port of the sampling tube 7 is fitted with a sealing plate 16 via a rotating shaft 15. A waterproof motor 17 is installed on the outer wall of the sampling tube 7, and the output end of the waterproof motor 17 is connected to one end of the rotating shaft 15. During operation, when adjusting the different depth positions of the sampling tube 7, the bottom port of the sampling tube 7 is in a state of being sealed by the sealing plate 16, which avoids the premature entry of materials during the movement of the sampling tube 7, reduces the error caused by the premature entry of materials, and ensures the accuracy of the sampling depth. When the sampling tube 7 reaches the designated depth for sampling, the waterproof motor 17 is started, causing the rotating shaft 15 to drive the sealing plate 16 to rotate from the original horizontal state to the vertical state, thereby opening the bottom port of the sampling tube 7. When the sampling tube 7 reaches the target depth, the bottom port is opened again for sampling. This can reduce the disturbance of materials during the sampling process, so that the sample obtained can more accurately reflect the properties of the material at that depth.

[0025] A protective cover 18 is fixed to the outer circumference of the sampling tube 7, and the waterproof motor 17 is installed inside the protective cover 18. When the device is in operation, the protective cover 18 can provide physical protection for the waterproof motor 17, reduce the risk of damage, and provide additional waterproof protection, reduce the possibility of water entering the motor, and ensure that the motor can work normally in humid environments such as underwater.

[0026] Please see Figure 3 As shown, a motor 19 is installed on the top of the reactor body 2. The output end of the motor 19 is connected to a stirring shaft 20. Multiple stirring blades 21 are fixed on the outer surface of the stirring shaft 20. A U-shaped scraper 22 is installed at the bottom end of the stirring shaft 20. A feed pipe 23 is connected to the top side of the reactor body 2, and a discharge pipe 24 is connected to the bottom of the reactor body 2. A second one-way valve is installed on the discharge pipe 24. During operation, when a chemical reaction is carried out, the motor 19 is started, which causes the stirring shaft 20 to drive the stirring blades 21 and the U-shaped scraper 22 to rotate. Through the synergistic effect of the stirring blades 21 and the U-shaped scraper 22, the materials in the reactor body 2 can be fully and evenly mixed, thereby improving the efficiency of the polymerization reaction and the product quality.

[0027] Please see Figure 1 As shown, the outer surface of the reactor body 2 is provided with an observation window 25 and a control panel 26 from bottom to top. The control panel 26 is used to control the start and stop of the pneumatic cylinder 4, the waterproof motor 17, and the electric motor 19. When using the device, the operator can intuitively see the mixing of materials, color changes, and the state of reactants through the observation window 25. This is very important for judging the reaction progress and whether the reaction conditions need to be adjusted. By setting up the control panel 26, this centralized control method greatly improves the convenience of operation and reduces the time and labor intensity of the operator to walk back and forth between different devices.

[0028] Working Principle: Existing reactor samplers can only sample from a single location, failing to accurately obtain samples at different depths. Single-location sampling only reflects the condition of that local area and cannot comprehensively reflect the true state of the materials inside the reactor, leading to misjudgments of the reaction process and difficulty in accurately determining whether the reaction has reached the expected endpoint, thus affecting the quality of the final product. Therefore, a reactor sampler is proposed to address these issues. Before sampling, the control panel 26 controls two pneumatic cylinders 4 to operate synchronously, causing two pneumatic rods 5 to move the lifting plate 6 up or down, thereby moving the sampling tube 7 accordingly. When the sampling tube 7 moves to the designated depth, the pneumatic cylinders 4 release their pressure. When the moving cylinder 4 stops operating, it enables precise sampling at different depths. By sampling at different depths, material samples from different areas within the reactor can be obtained, providing a more comprehensive picture of the composition, concentration, temperature, and other parameters of the materials within the reactor. This allows for a more accurate assessment of the reaction progress, ensuring precise control of reaction conditions and improving product quality. When adjusting the sampling tube 7 to different depths, the bottom end of the sampling tube 7 is sealed by the sealing plate 16, preventing premature material entry during the movement of the sampling tube 7. This reduces errors caused by premature material entry and ensures the accuracy of the sampling depth.

[0029] When the sampling tube 7 reaches the designated depth for sampling, the waterproof motor 17 is first started, causing the rotating shaft 15 to drive the sealing plate 16 to rotate from the original horizontal state to the vertical state, thereby opening the bottom port of the sampling tube 7. Then, the valve on the guide pipe 13 is opened, and the push-pull plate 12 is pulled upward, causing the movable rod 11 to drive the piston 10 upward, thereby extracting the reactants at the designated depth inside the reactor body 2 into the cylinder 9. After extraction, the valve on the guide pipe 13 is closed, the first one-way valve on the liquid outlet pipe 14 is opened, and the push-pull plate 12 is pressed downward, thereby allowing the sampling liquid in the cylinder 9 to flow into the sampling bottle through the liquid outlet pipe 14, thus completing the sampling operation. By opening the bottom port for sampling only after the sampling tube 7 reaches the target depth, the disturbance of the material during the sampling process can be reduced, making the sample more accurately reflect the properties of the material at that depth.
