Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel sampling and detection technology, specifically to a reaction vessel sampling and detection device. Background Technology
[0002] A reaction vessel is a sealed container, typically made of high-strength materials (such as stainless steel and fiberglass), possessing the characteristics of high temperature and high pressure resistance. It is primarily used to control and promote chemical reactions. By providing appropriate temperature, pressure, and stirring conditions, it allows reactants to undergo chemical changes within a certain time to obtain the desired product. In the petrochemical industry, reaction vessels are widely used in oil refining, ammonia synthesis, polymer production, and other processes. They are also required in the production of oilfield drilling fluid additives. In existing reaction vessels, the raw materials required for the additive are added into the vessel body, then stirred by a stirring device, and heated by a heating device to ferment the raw materials. Biochemical changes occur to form finished additives. During this process, it is necessary to sample the raw materials inside the reactor to analyze their chemical changes and mixing state. This process is often carried out by directly discharging a portion of the raw materials through the discharge pipe for sampling, and then detecting them through an external detection device. Traditional reactors sample and detect raw materials by directly discharging a portion of the raw materials through the discharge pipe. Due to the large internal capacity of the reactor, this sampling method can only collect raw materials at the discharge port and cannot effectively sample raw materials in other parts of the reactor. The single sampling location leads to a large sampling and detection error. Therefore, we propose a reactor sampling and detection device. Utility Model Content

[0022] Sampling mechanism 3 includes a sampling frame 31, a sampling head 32, and an arc-shaped limiting groove 33. The sampling frame 31 is rotatably connected to the middle of the top wall of the vessel body 1. The sampling head 32 is slidably connected to the middle of the inside of the sampling frame 31. The arc-shaped limiting grooves 33 are respectively opened on the left and right sides of the inner wall of the vessel body 1. The arc-shaped limiting grooves 33 are inclined grooves with the rear side higher than the front side. The two arc-shaped limiting grooves 33 are connected end to end to form a limiting slide. The end of the sampling head 32 away from the middle of the vessel body 1 is fitted with the inner wall of the arc-shaped limiting groove 33 to provide a basis for uniform sampling. The sampling mechanism 3 also includes a worm gear 34, a motor 35, and a worm 36. The worm gear 34 is set at the upper end of the sampling frame 31, and the motor 35 is set at the upper front side of the vessel body 1.

[0023] The working principle of the reaction vessel sampling and detection device provided by this utility model is as follows: Raw materials are fed into the reactor body 1 through the feed pipe 2. The microcontroller 9 controls the operation of the second motor 5. The output shaft of the second motor 5 drives the stirring frame 4 to rotate, stirring the surrounding raw materials to fully mix the different raw materials. At the same time, the microcontroller 9 controls the heating wire 6 to work. The heating wire 6 generates heat to heat the mixed raw materials, causing the raw material mixture to undergo a chemical change to form the finished product additive. After a period of time, it is necessary to sample the raw material mixture inside the reactor body 1. The microcontroller 9 controls the operation of the first motor 35. The output shaft of the first motor 35 drives the worm gear 36 to rotate. Because the worm wheel 34 is meshed with the worm gear 36, the worm wheel 34 also rotates, driving the sampling frame 31 to rotate synchronously. As the sampling frame 31 rotates, the sample is collected. The sampling head 32 also deflects. Since the end of the sampling head 32 away from the middle of the vessel body 1 is installed in conjunction with the inner wall of the arc-shaped limiting groove 33, the arc-shaped limiting groove 33 and the sampling frame 31 will simultaneously limit the sampling head 32. The sampling head 32 will move longitudinally with the rotation of the sampling frame 31, and the sampling head 32 will also move vertically along the trajectory of the arc-shaped limiting groove 33. At the same time, the microcontroller 9 controls the suction pump 37 to work. The suction pump 37 can perform sampling work at any position along the path of the sampling head 32 through the connecting pipe. Then, the sample is tested by the external detection device to realize sampling work at different heights and directions, which improves the accuracy of sampling and detection. When the sampling and detection are qualified, the microcontroller 9 controls the solenoid valve 7 to work. The solenoid valve 7 opens, and the finished additive can be quickly discharged.
[0024] It is worth noting that the microcontroller 9 disclosed in the above embodiments is an STM32F103RCT6 microcontroller, motor 35 is a 130ZFMA1-0003CBNM motor, suction pump 37 is a ROP-12A suction pump, motor 5 is a YL90L-61.1KW motor, heating wire 6 is a Ni80Cr20 heating wire, and solenoid valve 7 is a ZCS solenoid valve.
