Technical Field

[0001] This utility model relates to the field of pressure vessel technology, specifically to a chemical environmental protection pressure vessel with safety protection. 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. Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical, and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization, and condensation. Examples include reactors, reaction vessels, decomposition vessels, and polymerization kettles. Materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel, Inconel), and other composite materials. Chemical safety reaction vessels are widely used in the chemical industry due to their ease of processing and the high quality of the products they produce. When a chemical safety reaction vessel is in operation, the internal pressure needs to be observed through a pressure gauge on the surface. Currently, there are many types of chemical safety reaction vessels on the market.

Due to the complex working environment of the chemical safety reactor, the pressure gauges are prone to collisions and damage, resulting in low safety. They may also be corroded by splashes of chemical liquids. Therefore, a chemical environmental protection pressure vessel with safety protection is needed to solve the above problems.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1-4 As shown, this utility model provides a technical solution: a chemical environmental protection pressure vessel with safety protection, including a pressure vessel 1, a pressure gauge 2 installed at the top of the pressure vessel 1, a connecting component 3 at the outer end of the pressure gauge 2, a protective component 4 at the top of the connecting component 3, and a limiting component 5 for assembling the connecting component 3 at the side end. Through the cooperative arrangement of the connecting component 3, the protective component 4, and the limiting component 5, the pressure gauge 2 is completely enclosed, thus preventing the pressure gauge 2 from being directly exposed to the outside world and avoiding damage caused by collisions, thereby improving the safety of the pressure gauge 2. At the same time, it can also prevent the pressure gauge 2 from being corroded and damaged by splashes of chemical liquids.

[0021] As one implementation method in this embodiment, such as Figure 2 and Figure 4As shown, the connecting assembly 3 includes two connecting shells 301, both of which are located on both sides of the pressure gauge 2 pipeline. A sealing shell 302 and a sealing shell 306 are fixedly connected to the top of each connecting shell 301. A connecting shell 309 is fixedly connected to the top of both the sealing shell 302 and the sealing shell 306. A socket 303 is provided on the side of the sealing shell 302, and a connecting block 304 is fixedly connected to the side of the sealing shell 302. An installation groove 305 is provided inside the connecting block 304. An insert plate 307 is fixedly connected to the side of the sealing shell 306, and an insertion hole 308 is provided on the side of the insert plate 307, which is compatible with the socket 303. The protective assembly 4 includes a protective shell 401 and a protective shell 404. A sealing ring 402 is fixedly connected to the side of the protective shell 401, and a transparent plate 403 is fixedly connected to the side of the protective shell. The side end of the second protective shell 404 is provided with a sealing groove 405. The sealing ring 402 is adapted to the sealing groove 405. In practice, by clamping the first protective shell 302 and the second protective shell 404 to the outer end of the pressure gauge 2 as a whole, and then clamping the second protective shell 306 and the first protective shell 401 to the outer end of the pressure gauge 2 as a whole, the insert plate 307 is inserted into the insertion port 303, the sealing ring 402 is inserted into the sealing groove 405, and the transparent plate 403 can be inserted into the second protective shell 404. The limiting component 5 realizes the fixation between the first protective shell 302 and the second protective shell 306. At this time, the pressure gauge 2 is completely enclosed, which improves the safety of the pressure gauge 2. The setting of the transparent plate 403 makes it easy for personnel to observe the value of the pressure gauge 2 normally. Therefore, it can avoid the pressure gauge 2 being directly exposed to the outside world, avoid the pressure gauge 2 being damaged by collision, and also avoid the pressure gauge 2 being corroded and damaged by chemical liquid splashes.

[0022] As one implementation method in this embodiment, such as Figure 3 and Figure 4As shown, the limiting component 5 includes a pull head 501, with a round rod 502 fixedly connected to the side end of the pull head 501. The round rod 502 is inserted from the outer end of the connecting block 304 into the interior of the mounting groove 305. A round plate 503 is fixedly connected to the side end of the round rod 502, and an insert rod 504 is fixedly connected to the side end of the round plate 503. A spring 505 is sleeved on the outer end of the round rod 502. One end of the spring 505 is fixedly connected to the inner side end of the mounting groove 305, and the other end of the spring 505 is fixedly connected to the side end of the round plate 503. The insert rod 504 is adapted to the insertion hole 308. In practice, by pulling the pull head 501, the pull head 501 drives the round rod 502, the round plate 503, and the insert rod 504 to move. At this time, the round plate 503 presses against the spring 505 to retract, thereby locking the sealing shell 1 302 and the protective shell 2 404 in place. The outer end of the pressure gauge 2 is then secured with the sealing shell 306 and the protective shell 401. The insert plate 307 is then inserted into the socket 303, the sealing ring 402 is inserted into the sealing groove 405, and the transparent plate 403 is inserted into the protective shell 404. The insertion hole 308 on the side of the insert plate 307 is aligned with the insertion rod 504. After releasing the pull head 501, the spring 505 pushes against the circular plate 503, causing the insertion rod 504 to spring back and move. The insertion rod 504 then inserts into the insertion hole 308 on the side of the insert plate 307, thus fixing the insert plate 307. At this point, the sealing shell 302 and the sealing shell 306 are connected together, and the protective shell 401 and the protective shell 404 can also be connected together. The pressure gauge 2 is now completely enclosed, improving its safety.

[0023] Working principle: By pulling the pull head 501, the pull head 501 drives the round rod 502, round plate 503, and insert rod 504 to move. At this time, the round plate 503 compresses the spring 505 to retract, thereby securing the sealing shell 1 302 and the protective shell 2 404 to the outer end of the pressure gauge 2 as a whole. Then, the sealing shell 2 306 and the protective shell 1 401 are secured to the outer end of the pressure gauge 2 as a whole. At this time, the insert plate 307 is inserted into the socket 303, the sealing ring 402 is inserted into the sealing groove 405, and the transparent plate 403 can be inserted into the protective shell 2 404. At this time, the insertion hole 308 on the side of the insert plate 307 is aligned with the insert rod 504. After releasing the pull head 501, the spring 505 pushes against the round plate 502. 3. The insertion rod 504 is moved back and forth. At this time, the insertion rod 504 is inserted into the insertion hole 308 on the side of the insertion plate 307, thereby fixing the insertion plate 307. At this time, the sealing shell 1 302 and the sealing shell 2 306 are installed and connected together. The protective shell 1 401 and the protective shell 2 404 can also be connected together. At this time, the pressure gauge 2 is completely covered. The transparent plate 403 makes it easy for personnel to observe the value of the pressure gauge 2 normally. Therefore, the pressure gauge 2 is not directly exposed to the outside world, and the pressure gauge 2 is not damaged by collision, which improves the safety of the pressure gauge 2. At the same time, it can also prevent the pressure gauge 2 from being corroded and damaged by splashes of chemical liquids.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
