Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and in particular to a sealing and leak-proof device for a coating reaction vessel. Background Technology
[0002] A leak-proof sealing device for a coating reactor is a mechanical component installed at the connection between the stirring shaft and the reactor body to prevent the leakage of coatings, gases, and other media from the reactor, as well as the intrusion of external impurities. It typically consists of a dynamic ring, a static ring, a sealing ring, and a spring. The elastic element compresses the sealing surface to form a dynamic or static sealing structure. Different types of seals, such as packing seals or mechanical seals, can be selected based on the reactor's operating conditions (e.g., pressure, temperature, media characteristics) to ensure the sealing and safety of the reaction process and prevent material leakage that could lead to safety accidents or environmental pollution.
[0003] Existing reaction vessels stir the coatings during processing, which can easily cause the coatings to splash inside the vessel and seep out through the gaps between the sealing cap and the main body of the vessel. The seeping coatings can corrode the reaction vessel and surrounding equipment, shorten the service life of the equipment, pollute the workshop environment, increase cleaning and maintenance costs, and may also clog pipes and valves, affecting the normal operation of the production system. Furthermore, external impurities may enter the vessel through the gaps and contaminate the coatings, affecting the performance of the coatings and the product qualification rate. They may also change the composition of the reaction system, leading to uncontrolled reaction or impure products.
[0004] Therefore, we propose a sealing and leak-proof device for coating reaction vessels to solve the above problems. Utility Model Content

[0022] Reference Figure 1-6 A sealing and leak-proof device for a coating reaction vessel includes a reaction vessel body 1, a sealing ring seat 8 fixedly installed on the inner side of the reaction vessel body 1, a sealing base 12 slidably sleeved on the outer side of the sealing ring seat 8, and the outer side of the sealing base 12 slidingly contacting the inner wall of the reaction vessel body 1; a sealing groove is opened on the top of the reaction vessel body 1, and a sealing cover 4 is provided on the top of the reaction vessel body 1, and the reaction vessel body 1 is connected to the sealing cover 4 flange by bolts.
[0023] In this embodiment, a support 2 is fixedly sleeved on the outside of the reactor body 1, which can enhance the stability of the reactor body 1 when it is placed.
[0024] In this embodiment, an electrically controlled valve 3 is fixedly installed at the bottom of the reactor body 1 to facilitate material discharge.
[0025] In this embodiment, an inflatable rubber ring 5 is fixedly installed on the inner side of the sealing groove, and a connecting pipe 14 is fixedly installed at the air inlet of the inflatable rubber ring 5.
[0026] In this embodiment, an inflation shell 6 is fixedly installed on the outer side of the reactor body 1, and an inflation chamber is opened on the inner side of the inflation shell 6. An air pump 7 is fixedly installed on the inner side of the inflation chamber, and the output end of the air pump 7 is fixedly connected to the other end of the connecting pipe 14 to facilitate inflation of the inflation rubber ring 5.
[0027] In this embodiment, the outer side of the sealing ring seat 8 is provided with an external threaded groove 9, and the top of the sealing base 12 is provided with a threaded hole. The threaded hole is threadedly connected to the external threaded groove 9. Multiple handles 13 are fixedly installed on the top of the sealing base 12 to facilitate the rotation of the sealing base 12 by the operator.
[0028] In this embodiment, a sealing bracket 10 is fixedly installed on the inner side of the sealing ring seat 8, and a conical head 11 is fixedly installed on the top of the sealing bracket 10.
[0029] In this embodiment, a stirring shaft 15 is rotatably mounted on the bottom of the sealing bracket 10. Multiple stirring blades 16 are fixedly sleeved on the stirring shaft 15. A motor slot is opened inside the sealing bracket 10. A servo motor 17 is fixedly mounted on the top inner wall of the motor slot. The output shaft of the servo motor 17 is fixedly connected to the stirring shaft 15, and the stirring shaft 15 can be driven to rotate by the servo motor 17.
[0030] Working principle: During paint processing, after removing the sealing cap 4, the operator rotates the sealing base 12 clockwise using the handle 13. The sealing base 12 rotates and fits onto the sealing ring seat 8. The outer side of the sealing ring seat 8 has an external threaded groove 9, and the top of the sealing base 12 has a threaded hole. The threaded hole is threadedly connected to the external threaded groove 9. Therefore, when the sealing base 12 rotates, it moves axially. The sealing base 12 moves downward along the outer side of the sealing ring seat 8, releasing the seal on the top opening of the sealing ring seat 8. The operator pours the paint particles into the reactor body 1. The paint particles fall onto the conical head 11 and then fall through the sealing ring seat 8 into the internal cavity of the reactor body 1. Then, the operator rotates the handle clockwise... The dynamic sealing base 12 is reset, and after sealing the sealing ring seat 8, the sealing cover 4 is connected to the flange of the reactor body 1 by bolts. Then, the air pump 7 is started, and the air pump 7 generates gas, which is inflated through the connecting pipe 14 to inflate the air-filling rubber ring 5, filling the gap between the sealing cover 4 and the reactor body 1. This prevents external dust, water vapor and other impurities from entering the reactor through the gap, avoiding contamination of the reaction materials and improving the product qualification rate. At the same time, it also prevents the seeping coating from corroding the reactor and surrounding equipment, reducing the frequency of equipment maintenance and replacement. Then, the servo motor 17 is started, which drives the stirring shaft 15 to rotate, and then drives multiple stirring blades 16 to rotate, stirring the coating particles and carrying out the reaction.
[0031] The technological advancements of this invention compared to existing technologies are as follows: By controlling the lifting and lowering of the sealing base 12, the sealing ring seat 8 can be sealed to prevent coating from overflowing. Simultaneously, the inflatable rubber ring 5, which can be inflated using the air pump 7, fills the gap between the sealing cover 4 and the reactor body 1. This prevents external dust, moisture, and other impurities from entering the reactor through the gap, avoiding contamination of the reactants, maintaining the stability of the reaction system composition, ensuring coating performance meets standards, and improving product qualification rates. It also prevents leaked coating from corroding the reactor and surrounding equipment, reducing equipment maintenance and replacement frequency. Furthermore, it prevents coating from clogging pipes and valves, ensuring long-term stable operation of the production system and reducing equipment maintenance costs.
