Description

Technical Field

[0001] This utility model relates to the field of hydrogenation reactor technology, specifically a sampling device for a hydrogenation reactor. Background Technology

[0002] In a broad sense, a reaction vessel is a container that undergoes physical or chemical reactions. Through structural design and parameter configuration, it achieves the heating, evaporation, cooling, and low-to-high-speed mixing functions required by the process. A reaction vessel is a stainless steel container that undergoes physical or chemical reactions. The structural design and parameter configuration of the reaction vessel are based on different process requirements. The design conditions, processes, inspection, manufacturing, and acceptance must be in accordance with relevant technical standards. A reaction vessel is a comprehensive reaction container, and when using it, it is necessary to sample the liquid inside.

[0003] A search revealed a sampling device for a hydrogenation reactor published in Chinese Patent No. CN212882372U. The key technical point of this device is that it solves the problem that in the production process of existing chemical equipment, sampling requires manual insertion of a long measuring bucket into the inner cavity of the reactor, which is time-consuming and laborious, easily leads to liquid waste, reduces the user's efficiency, and fails to meet the user's needs.

[0004] However, the above-mentioned solutions have found that when sampling liquids, since no quantitative structure is set up, when the liquid is transferred to the measuring cylinder through the drain pipe, even if the sliding stop and the water-proof pad can prevent backflow, the liquid in the drain pipe still exists and will continue to flow into the measuring cylinder, resulting in excessive or insufficient sampling, which easily leads to liquid waste and insufficient dosage. In order to solve the problem of the inability to quantitatively sample in the prior art, which leads to excessive or insufficient sampling, liquid waste and insufficient dosage, this application proposes to set up a liquid level sensing block and a piston block in the device. By adjusting the position of the liquid level sensing block, the lowering of the piston block facilitates quantitative extraction of liquid, and the raising of the piston block facilitates the transfer of liquid to the measuring cup, achieving the effect of quantitative sampling of this device and preventing excessive or insufficient sampling, liquid waste or insufficient sampled liquid dosage. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] The existing technology mentioned above has the shortcomings and defects of not being able to quantitatively sample, which leads to excessive or insufficient sampling, resulting in waste of liquid and insufficient dosage.

[0006] This utility model discloses a sampling device for a hydrogenation reactor, comprising a measuring cylinder and a motor. The output shaft of the motor is fixedly connected to a threaded rod, and a guide rod is threadedly connected to the outer surface of the threaded rod. A piston block is fixedly connected to the top end of the guide rod, and the outer surface of the piston block is slidably connected to the inner wall of the measuring cylinder. A limiting member is fixedly connected to the outer surface of the measuring cylinder, and a threaded rod is rotatably connected to the inner wall of the limiting member. A threaded block is threadedly connected to the outer surface of the threaded rod, and a liquid level sensing block is fixedly connected to the right side of the threaded block. The outer surface of the threaded block is slidably connected to the inner wall of the limiting member.

[0007] Furthermore, a pipe is fixedly connected to the upper surface of the measuring cylinder, and a one-way valve is provided on the outer surface of the pipe. A water outlet pipe is fixedly connected to the outer surface of the measuring cylinder, and a two-way valve is provided on the outer surface of the water outlet pipe.

[0008] Furthermore, a base plate is fixedly connected to the upper surface of the motor, and a set of equidistant limiting rods is fixedly connected to the upper surface of the base plate. The top end of each set of limiting rods is fixedly connected to the bottom surface of the measuring cylinder.

[0009] Furthermore, a limiting plate is fixedly connected to the bottom end of the guide rod, and the outer surface of each limiting rod is slidably connected to the inner wall of the limiting plate.

[0010] Furthermore, the left end of the pipeline is fixedly connected to a reaction vessel, and the bottom surface of the reaction vessel is fixedly connected to a motor.

[0011] Furthermore, the output shaft of the second motor is fixedly connected to a connecting rod, and the outer surface of the connecting rod is fixedly connected to stirring rods arranged at equal intervals.

[0012] Furthermore, a mounting bracket is fixedly connected to the outer surface of the reactor, a mounting base is fixedly connected to the upper surface of the mounting bracket, and a measuring cup is provided on the inner wall of the mounting base.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up components such as a threaded rod, a guide rod, a piston block, a threaded rod, a second threaded rod, a threaded block, and a liquid level sensing block, allows the operator to manually rotate the second threaded rod before hydrogen sampling. This causes the threaded block to move up and down within the limiting component, thereby moving the liquid level sensing block up and down to adjust its position. At this time, motor one is started, causing the threaded rod one to rotate. Through the connection between the threaded rod one and the guide rod, the guide rod descends, causing the piston block to descend within the measuring cylinder, drawing up the sample liquid until it is level with the liquid level sensing block. The liquid level sensing block senses the liquid level and automatically stops motor one, achieving the effect of quantitative sampling and preventing excessive or insufficient sampling, thus preventing liquid waste or insufficient sample dosage.

[0015] 2. This utility model incorporates components such as a pipe, a first check valve, a water outlet pipe, a second check valve, a connecting rod, and a stirring rod. The pipe is positioned with the first check valve on its surface, and the water outlet pipe has the second check valve on its surface. When the piston block descends, the first check valve opens, allowing liquid inside the pipe to be drawn into the measuring cylinder. At this time, the second check valve closes. When the piston block rises, the second check valve opens, and the first check valve closes, allowing liquid inside the measuring cylinder to be discharged through the water outlet pipe to the measuring cup, thus achieving liquid transfer and preventing backflow of the measured liquid. The second motor, connecting rod, and stirring rod facilitate stirring of the liquid inside the reaction vessel. Attached Figure Description

[0027] In a preferred embodiment, a base plate 14 is fixedly connected to the upper surface of the motor 2. The base plate 14 is installed on the upper surface of the motor 2. The motor 2 is a micro motor, and the base plate 14 supports the motor 2. A set of equally spaced limiting rods 15 are fixedly connected to the upper surface of the base plate 14. The limiting rods 15 are installed on the upper surface of the base plate 14 and are fixedly connected to achieve the installation of the limiting rods 15. The top end of each limiting rod 15 is fixedly connected to the bottom surface of the measuring cylinder 1. The top end of the limiting rod 15 is connected to the bottom surface of the measuring cylinder 1 to achieve the installation of the limiting rods 15 and the base plate 14.

[0028] In this embodiment, a limiting plate 16 is fixedly connected to the bottom end of the guide rod 4. The limiting plate 16 is installed at the bottom end of the guide rod 4 and is set as a fixed connection. The outer surface of each limiting rod 15 is slidably connected to the inner wall of the limiting plate 16. The surface of the limiting rod 15 is connected to the limiting plate 16 and is set as a sliding connection. The limiting plate 16 can be limited by the limiting rod 15, thereby limiting the guide rod 4 and ensuring that the guide rod 4 can only slide up and down.

[0029] Combination Figure 1 and Figure 3 The left end of the pipe 10 is fixedly connected to the reactor 17. The reactor 17 is set at the left end of the pipe 10 and connected. The liquid contained in the reactor 17 can be extracted through the pipe 10. The bottom surface of the reactor 17 is fixedly connected to the motor 18. The motor 18 is installed on the bottom surface of the reactor 17 to achieve the positioning and installation effect of the motor 18.

[0030] In a preferred embodiment, a connecting rod 19 is fixedly connected to the output shaft of motor 18. The connecting rod 19 is fixed to the output shaft of motor 18, and the motor 18 can be used to rotate the connecting rod 19. Stirring rods 20 arranged at equal intervals are fixedly connected to the outer surface of the connecting rod 19. The stirring rods 20 are installed on the outer surface of the connecting rod 19, and the connecting rod 19 can be rotated to rotate the stirring rods 20, which facilitates stirring of the liquid inside the reaction vessel 17.

[0031] In this embodiment, a mounting bracket 21 is fixedly connected to the outer surface of the reactor 17.

A groove is opened on the upper surface of the mounting seat 22 to facilitate the placement of the measuring cup 23.

[0032] The implementation principle is as follows: The measuring cup 23 is placed in the groove on the surface of the mounting base 22 to limit the position of the measuring cup 23. At this time, the operator manually rotates the threaded rod 7, causing the threaded block 8 to move up and down on the inner wall of the limiting part 6, which in turn drives the liquid level sensing block 9 to move up and down, thereby adjusting the position of the liquid level sensing block 9. Then, the motor 2 is started, causing the threaded rod 3 to rotate. Through the connection between the threaded rod 3 and the guide rod 4, the guide rod 4 is lowered, which drives the piston block 5 to descend on the inner wall of the measuring cylinder 1. The sampled liquid is drawn through the pipe 10 and the one-way valve 11 until the liquid is level with the liquid level sensing block 9. The liquid level sensing block 9 senses the liquid level and automatically stops the motor 2. Then, the reverse rotation of the motor 2 causes the piston block 5 to rise. At this time, the one-way valve 13 on the surface of the outlet pipe 12 opens, and the liquid is squeezed out of the measuring cylinder 1 and flows into the measuring cup 23 below, achieving the effect of quantitative sampling and preventing waste of liquid due to excessive or insufficient sampling.
