Description

Technical Field

[0001] The utility model relates to the technical field of chemical reactors, in particular to a chemical safety reactor which is convenient for sampling. Background Art

[0002] Reactor is a chemical equipment used for chemical reactions. It is mainly used for heat transfer and material mixing during chemical production. The agitator inside the reactor ensures uniform mixing of materials. Reactors are usually equipped with safety devices, such as pressure gauges, safety valves and temperature sensors, to monitor and control reaction conditions and prevent dangerous situations such as overheating and overpressure. The working principle of the reactor is an important part of chemical engineering. Its safety and efficiency are crucial to the smooth progress of chemical reactions. When the reactor is working, it is necessary to monitor the reaction process, control product quality, optimize reaction conditions, etc. by sampling. Through sampling, we can better understand the reaction process, improve reaction efficiency and product quality, and ensure the safety of the reaction. The existing sampling method usually uses suitable sampling equipment, such as sampling tubes, sampling spoons, etc., to manually insert samples into the reactor through the sampling port, and slowly take out the sample after sampling to avoid splashing or overflowing. After sampling, close the sampling port.

[0003] For some materials with strict requirements or that will react with air, air should be prevented from entering the reactor as much as possible. However, in the above-mentioned sampling process, the sampling port is generally open, and external gas can easily enter the reactor, which can easily reduce the efficiency of chemical production. When sampling, the sampling equipment should be smoothly extended into the reactor to ensure the accuracy of sampling. However, the existing sampling equipment is not easy to control for deeper sampling equipment and has certain operating difficulties. Utility Model Content

A spring 42 is installed at the top of the connection, a piston plug 43 is inserted into the lower half of the lifting rod 41, and a sealing gasket 44 is bonded to the outside of the piston plug 43. The sampling tube 3 is inserted into the reactor body 1 from above the sampling port 2, and the top of the sampling tube 3 blocks the top of the sampling port 2 to prevent external gas from entering the reactor. The bristles 22 inside the sampling port 2 cooperate with the cleaning sleeve 21 to guide and limit the sampling tube 3 when the sampling tube 3 enters the reactor body 1, so as to ensure that the sampling tube 3 enters the reactor body 1 smoothly and quickly. A feeding hole 11 is arranged above the reactor body 1, and a discharge port 12 is connected to the bottom of the reactor body 1, and a discharge valve is installed on the discharge port 12 13. An electric motor 14 is installed on the top of the reactor body 1, and a stirring rod 15 is connected to the bottom of the electric motor 14. When using the device, the feeding hole 11 puts the material into the reactor body 1, and the electric motor 14 drives the stirring rod 15 to stir the material. After the stirring is completed, the discharge valve 13 can be opened to discharge the raw materials quickly through the discharge port 12. The cleaning sleeve 21 and the sampling port 2 are plug-in connected, and the cleaning sleeve 21 and the sampling port 2 are fixed by bolts. The plug-in connection can ensure the airtightness of the connection between the cleaning sleeve 21 and the sampling port 2, and the position of the cleaning sleeve 21 can be reliably fixed by bolts. The upper and lower sides of the cleaning sleeve 21 are set with expansion holes, and the cleaning sleeve 2 set with expansion holes is set with expansion holes. 1 can facilitate the sampling tube 3 to enter the interior of the reactor body 1 through the guidance of the cleaning sleeve 21, and can also guide and limit the sampling tube 3. The lifting rod 41 and the sampling tube 3 form a lifting installation structure through the telescopic motor 4, and the lifting rod 41 and the sampling tube 3 are arranged with an axis overlap. The lifting rod 41 is pulled down by the telescopic motor 4, which can drive the piston plug 43 to separate from the sampling tube 3, and the material enters the sampling cavity inside the sampling tube 3, which can facilitate sampling. The spring 42 and the lifting rod 41 are arranged with an axis overlap. The spring 42 arranged with an axis overlap can drive the lifting rod 41 to rise smoothly, which is convenient for the spring 42 to reset. The sampling tube 3 is provided with a sampling feed hole near the piston plug 43.The feed hole can facilitate the raw materials inside the reactor body 1 to enter the sampling cavity inside the sampling tube 3. The sampling tube 3 is provided with a sampling cavity inside, and the sampling cavity is connected to the connecting airway 35. The vacuum pump 31 can quickly extract the air inside the sampling cavity through the connecting airway 35.

[0035] The working principle of the utility model is as follows: when using the device, the feeding hole 11 puts the material into the reactor body 1, and the electric motor 14 drives the stirring rod 15 to stir the material. Before sampling, the electric motor 14 and the stirring rod 15 are turned off, and then the sampling port 2 is opened, and the sampling tube 3 is inserted into the reactor body 1 from above the sampling port 2. The top of the sampling tube 3 blocks the top of the sampling port 2. At this time, the vacuum pump 31 extracts the air inside the sampling chamber through the connecting airway 35. After the air is extracted, the telescopic motor 4 pulls the lifting rod 41 down, and the lifting rod 41 drives the piston plug 43 and the sealing gasket 44 to separate from the sampling tube 3. The raw materials inside the reactor body 1 enter the sampling chamber inside the sampling tube 3. After sampling, the telescopic motor 4 and the spring 42 drive the lifting rod 41 and the piston plug 43 to rise to sample the sampling tube 3. After plugging, the device is pulled out from the sampling port 2. During the process of pulling out the sampling tube 3, the bristles 22 inside the cleaning sleeve 21 are used to scrape off the raw materials adhered to the sampling tube 3, and then the raw materials in the sampling tube 3 are transferred to the inside of the sample box. After the transfer is completed, the sample can be tested. After the test, the water valve 34 is used to connect with the high-pressure water pipe, and water enters the interior of the sampling tube 3. Through the connecting airway 35, it can reach all parts of the interior of the sampling tube 3, and the sampling cavity inside the sampling tube 3 is comprehensively and reliably cleaned. During the sampling process, the sampling tube 3 can block the sampling port 2 to prevent external gas from entering the interior of the reactor, and the bristles 22 and the cleaning sleeve 21 can be used to guide and limit the sampling tube 3 when the sampling tube 3 enters the interior of the reactor body 1, so as to ensure that the sampling tube 3 enters the interior of the reactor body 1 smoothly and quickly.
