Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for the production of chemical products. Background Technology

[0002] In the production of chemical products, reaction vessels are often used as reaction containers. After the reaction is completed, a large amount of material will adhere to the inner wall of the reaction vessel. In order to avoid contamination of the next batch of material, the reaction vessel needs to be cleaned.

[0003] In existing technologies, multiple nozzles are often installed at the bottom of the top cover of a reactor to achieve automated cleaning. However, during the production of chemical products, corrosive acid mists may be generated. Continuous entry of these acid mists into the nozzles can cause corrosion, affecting their lifespan and water spraying efficiency. Furthermore, rust generated inside the nozzles may fall into the materials inside the reactor, contaminating them and adversely impacting the production of chemical products. Utility Model Content

[0004] The purpose of this invention is to provide a reaction vessel for chemical product production. By setting up a shielding device, the nozzle can be blocked, thereby effectively preventing acid mist and other corrosive substances from corroding the nozzle, effectively improving the service life of the nozzle, and preventing the rust from the nozzle from contaminating the materials in the reaction vessel.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A reaction vessel for producing chemical products includes a reaction vessel body, a top cover detachably mounted on the top of the reaction vessel body, two sets of water spray sections mounted on the bottom of the top cover, and a water supply device connected to the water spray sections; each set of water spray sections is detachably mounted with a protective cover with a top opening, and the top of the protective cover is detachably connected to the top cover.

[0007] Preferably, each group of water spray sections includes multiple nozzles, and all the nozzles in the two groups of water spray sections can form a circle at the bottom of the top cover.

[0008] Preferably, each of the protective covers has a sealing end at its top and a closed groove at its bottom that is interference-fitted with the sealing end.

[0009] Preferably, the protective cover is made of acid- and alkali-resistant material.

[0010] Preferably, the water supply device includes a water distribution pipe disposed at the top of the top cover and connected to each of the nozzles, a main water pipe connected to the common water inlet of all the water distribution pipes, and a water tank connected to the water inlet of the main water pipe.

[0011] Preferably, each of the protective covers has at least two handles at its bottom.

[0012] Preferably, a rotating shaft is provided inside the reactor body, and multiple stirring rods are provided outside the rotating shaft. The rotating shaft is fixedly connected to the output end of a motor located at the top of the top cover.

[0013] Preferably, the top cover is connected to an air duct, the air outlet of the air duct is located inside the protective cover, and the air inlet of the air duct is connected to a fan.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By installing two sets of water spray sections at the bottom of the top cover and a water supply device connected to the water spray sections, water can be supplied to the water spray sections after the reaction of the materials in the reactants is completed, and then sprayed along the water spray sections into the reactor body, thereby achieving the purpose of automated cleaning of the reactor body. By installing a protective cover with a top opening on the outside of each set of water spray sections, and making the top cover detachable on the top of the reactor body, the protective cover can be placed over the two water spray sections in advance during the chemical product reaction process to protect the water spray sections. This prevents corrosive acid mist generated during the chemical production process from entering the water spray sections and causing corrosion, which would affect the service life and effectiveness of the water spray. It also prevents rust generated by the water spray sections from falling directly into the materials in the reactor, thus preventing material contamination. Attached Figure Description

[0022] Example 1

[0023] A reaction vessel for the production of a chemical product, such as Figure 1 and Figure 2 As shown, the reactor includes a reaction vessel body 1, a top cover 2 detachably mounted on the top of the reaction vessel body 1, two sets of water spray sections mounted on the bottom of the top cover 2, and a water supply device connected to the water spray sections; each set of water spray sections is detachably equipped with a protective cover 3 with a top opening, and the top of the protective cover 3 is detachably connected to the top cover 2. Further, as... Figure 3 As shown, each group of water spray sections includes multiple nozzles 4. All the nozzles 4 in both groups of water spray sections can form a circle at the bottom end of the top cover 2, so that the nozzles 4 are evenly distributed at the bottom end of the top cover 2, for the purpose of uniformly spraying water into the reactor body 1. The direction of the nozzles 4 can be adjusted arbitrarily according to actual conditions, so as to achieve uniform water spraying into the reactor body 1. Furthermore, as... Figure 1 and Figure 3 As shown, a rotating shaft 10 is installed inside the reactor body 1, and multiple stirring rods 11 are installed outside the rotating shaft 10. The rotating shaft 10 is fixedly connected to the output end of a motor 12 located at the top of the top cover 2. Figure 3 As shown, two protective covers 3 are respectively set on both sides of the rotating shaft 10. Compared with directly setting the protective cover 3 as a closed ring, setting two protective covers 3 makes it easier to disassemble and install. They can be disassembled individually without having to penetrate the stirring rod 11, making the operation more convenient. Furthermore, as... Figure 4 and Figure 5 As shown, the water supply device includes a water distribution pipe 7 located at the top of the top cover 2 and connected to each of the nozzles 4, a main water pipe 8 (the main water pipe 8 is a flexible hose) connected to the common inlet end of all the water distribution pipes 7, and a water tank connected to the inlet end of the main water pipe 8. A water pump is also installed on the main water pipe 8. The water pump and the water tank are existing technologies and are not shown in the figure. Furthermore, a support leg is provided at the bottom of the reactor body 1, and a discharge port is provided on the bottom wall of the reactor body 1. Since the support leg and the discharge port are existing technologies, they are not shown in the figure.

[0024] Working principle: When producing chemical products, two protective covers 3 are installed at the bottom of the top cover 2 in advance. Then, the top cover 2 is placed on the top of the reactor body 1. Locking can be done using a latch or other existing technology. After that, production is carried out according to existing technology. Because of the protective covers 3, corrosive substances generated by chemical products can be blocked, preventing them from directly escaping into the nozzle 4, thus effectively protecting the nozzle 4. This also prevents corrosive acid mist generated during the chemical production process from entering the nozzle 4 and causing corrosion, which would affect the service life and water spraying efficiency. It also prevents rust generated by the nozzle 4 from falling directly into the material in the reactor and causing material contamination. After the reaction is complete, the material is removed from the discharge port. Then, the top cover 2 is opened and the two protective covers 3 are removed from the bottom of the top cover 2. The top cover 2 is then replaced and the water pump is turned on so that the water in the water tank is fed into the nozzle 4 along the main water pipe 8 and the branch water pipe 7, and then sprayed into the reactor body 1 along the nozzle 4 to flush down the material remaining in the reactor body 1, thereby achieving the purpose of cleaning the reactor body 1.

[0025] Furthermore, to further improve the installation firmness and sealing performance of the protective cover 3, each of the protective covers 3 is provided with a sealing end at its top (i.e., a sealing ring, etc., in the prior art, not shown in the figure), such as... Figure 3 As shown, the bottom end of the top cover 2 is provided with a closed groove 6 that is interference-fitted with the sealing end. During specific installation, the sealing end is interference-fitted into the closed groove 6 to achieve the purpose of firmly installing the protective cover 3 in the closed groove 6. Because the sealing end and the closed groove 6 are interference-fitted, the sealing end can be firmly installed in the closed groove 6.

[0026] Furthermore, in order to reduce the corrosion of the protective cover 3 by corrosive substances generated during the production of chemical products, the protective cover 3 is made of acid and alkali resistant materials with certain high temperature resistance, such as polytetrafluoroethylene resin, in actual use.

[0027] Furthermore, to facilitate the installation and removal of the protective cover 3, such as... Figure 1 and Figure 2 As shown, each of the protective covers 3 is provided with at least two handles 9 at its bottom. In this solution, by providing handles 9, workers can hold the handles 9 during installation or disassembly, improving the ease of operation.

[0028] Furthermore, after the reactor body 1 is cleaned, its interior is damp. Allowing it to dry naturally takes a long time, affecting subsequent reactions. In addition, it may breed bacteria and cause corrosion of internal components. Therefore, if... Figure 4As shown, the top cover 2 is connected to an air duct 13. The air outlet of the air duct 13 is located inside the protective cover 3, so that the protective cover 3 protects the air duct 13 and prevents corrosive substances generated during the chemical production process from adversely affecting the air duct 13. The air inlet of the air duct 13 is connected to a fan 14. In addition, in actual implementation, a heating wire can also be installed inside the air duct 13 to improve the drying speed. During drying, the fan 14 is turned on to allow air to quickly enter the reactor body 1 to achieve the purpose of rapid drying.
