Description

Technical Field

[0001] This utility model belongs to the technical field of resin processing equipment, and specifically relates to a cleaning device for a reaction vessel used in resin processing. Background Technology

[0002] Resin is an organic polymer that can be synthesized from monomers into high molecular weight compounds through chemical reactions. Resins can be classified into thermoplastic resins and thermosetting resins according to their processing behavior. Thermoplastic resins soften when heated and can be repeatedly shaped, returning to a solid state after cooling. Thermosetting resins, on the other hand, solidify when heated, forming an insoluble and infusible hard material. Resin processing reactors are common high-pressure reaction equipment specifically used for resin preparation, catalytic reactions, polymerization reactions, etc. They can withstand high pressure and high temperature conditions while ensuring the safety and stability of the reaction process, and have wide applications in resin synthesis, chemical industry, pharmaceutical industry and other fields.

[0003] The reactor needs to be cleaned promptly after use. If it is not cleaned for a long time, the resin solution adhering to the inner wall of the reactor may solidify and form scale that is difficult to clean. In subsequent use, this scale will not only reduce the heat transfer efficiency of the reactor, thus failing to achieve the required melting effect in the same amount of time, but may also affect product quality, even cause corrosion problems, and shorten the service life of the reactor. If the cleaning method is not chosen properly or the cleaning depth is insufficient, the solidified solution scale may not be completely removed, resulting in dirt residue inside the reactor, forming cleaning dead spots, and leading to poor cleaning quality.

[0004] Therefore, this utility model provides a cleaning device for a reaction vessel used in resin processing. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example: Figures 1-5 The shown is a cleaning device for a resin processing reactor, including a mounting base 1 and a drive shaft 3. A cleaning mechanism 6 is fixedly connected to the lower end of the drive shaft 3. Clamping mechanisms 4 are provided on both sides of the mounting base 1, and a spraying mechanism 5 is provided at the bottom of the mounting base 1. The clamping mechanism 4 includes a set of clamping plates 45 that are slidably connected to the mounting base 1. The spraying mechanism 5 includes a set of nozzles 52 that are fixedly installed at the bottom of the mounting base 1. The cleaning mechanism 6 includes a scraper 62 that is in contact with the inner wall of the reactor. The scraper 62 is an arc-shaped curved surface, and a guide groove 63 is provided on one side of the scraper 62.

[0026] In this embodiment, the equipment is placed on top of the reactor, allowing the scraper 62 to enter the reactor. The scraper 62 is positioned so that the positioning plate 2 at the bottom of the mounting base 1 is in contact with the inner wall of the reactor. At this point, one side of the scraper 62 is completely in contact with the inner wall of the reactor. The screw 43 is rotated, causing the two symmetrical clamping plates 45 on the mounting base 1 to simultaneously move towards the outer wall of the reactor, thus fixing the mounting base 1. The drive motor and sprayer 51 are then turned on. The drive motor causes the scraper 62 to rotate while remaining close to the inner wall of the reactor, and the sprayer 51 causes the nozzle 52 to spray water towards the upper part of the inner wall of the reactor. During the rotation of the scraper 62, dirt on the inner wall is scraped away, and the water sprayed from the nozzle 52 flows downwards. The curved scraper 62, in conjunction with the water sprayed from the nozzle 52, enhances the cleaning effect on the inner wall of the reactor. The guide groove 63 on the scraper 62 guides the water flow and the scraped dirt towards the bottom of the reactor.

[0027] like Figures 1-4As shown, an annular positioning plate 2 is fixedly connected to the bottom of the mounting base 1. The outer wall of the positioning plate 2 is in contact with the inner wall of the reactor. A drive motor is fixedly installed on the top of the mounting base 1. The output end of the drive motor is fixedly connected to the drive shaft 3. The drive shaft 3 rotates through the mounting base 1. A clamping mechanism 4 is assembled to fix the position of the mounting base 1 when the cleaning mechanism 6 is working. The clamping mechanism 4 also includes a set of connecting seats 41 fixedly connected to the outside of the mounting base 1. A sliding groove 42 is opened in the connecting seat 41. A screw 43 is rotatably connected in the sliding groove 42. The screw 43 rotates through the mounting base 1 and the connecting seat 41. Slider 44 is threaded to both ends of the screw 43. The slider 44 is slidably connected to the sliding groove 42. The lower end of the slider 44 is fixedly connected to the clamping plate 45 on the side near the reactor. The side of the clamping plate 45 near the outer wall of the reactor is arc-shaped and equipped with a rubber pad.

[0028] In this embodiment, when placing the device, when the positioning plate 2 at the bottom of the mounting base 1 is in contact with the upper end of the inner wall of the reactor, the knob at the end of the screw 43 is rotated, so that the two sliders 44 threadedly connected to the screw 43 move closer to each other and slide in the groove 42. When the screw 43 can no longer rotate, it means that the two clamping plates 45 are in contact with the outer wall of the reactor and clamp the reactor. The rubber pads on the clamping plates 45 can increase the friction and keep the mounting base 1 stable when the cleaning mechanism 6 is working, avoiding shaking. When disassembly is required, the knob at the end of the screw 43 is rotated in the opposite direction to make the two clamping plates 45 move away from each other and separate from the reactor.

[0029] like Figure 2 , Figure 4 and Figure 5 As shown, the spraying mechanism 5 is assembled to spray water onto the upper part of the inner wall of the reactor through the nozzle 52; the spraying mechanism 5 includes a sprayer 51 fixedly installed on the top of the mounting base 1, the sprayer 51 is fixedly connected to a set of nozzles 52, and the nozzles 52 are fixedly connected to the bottom of the mounting base 1; the cleaning mechanism 6 is assembled to remove dirt from the inner wall of the reactor by rotating the scraper 62; the cleaning mechanism 6 also includes a connecting block 61 fixedly connected to the lower end of the drive shaft 3, and the connecting block 61 is fixedly connected to the top of the scraper 62.

[0030] In this embodiment, after the clamping mechanism 4 is connected to the reactor, the drive motor and sprayer 51 are started. The scraper 62 rotates to scrape off the dirt on the inner wall of the reactor. The nozzle 52 sprays water from the upper part of the inner wall of the reactor, which makes the dirt easier to remove and enhances the cleaning effect. When the scraper 62 rotates, the dirt and water move towards the bottom of the reactor under the guidance of the scraper 62. The angle formed between the scraper 62 and the inner wall of the reactor can reduce the splashing caused when scraping the inner wall. Some of the splashed dirt and water are intercepted by the scraper 62 to avoid splashing onto the already cleaned inner wall. After being intercepted by the scraper 62, the dirt moves downward under the guidance of the guide groove 63. The curved surface of the scraper can also prolong the residence time of water on the inner wall of the reactor, which is conducive to the removal of dirt. The scraper 62 is always in contact with the inner wall of the reactor when it rotates, and at the same time cleans the side wall and bottom of the reactor.

[0031] Working principle: During use, the device is placed on top of the reactor, allowing the scraper 62 to enter the reactor interior. The positioning plate 2 is in contact with the upper end of the reactor's inner wall. Rotating the screw 43 causes the slider 44 to slide within the groove 42, moving the clamping plate 45 closer to the reactor. When the screw 43 cannot rotate, the clamping plate 45 clamps the reactor. The mounting base 1 remains stable while the cleaning mechanism 6 is operating. After the mounting base 1 is fixed, the drive motor and sprayer 51 are started. Water sprayed from the nozzle 52 flows downwards onto the inner wall of the reactor. As the scraper 62 rotates, it scrapes away the dirt adhering to the inner wall of the reactor. The water on the inner wall helps to remove the dirt and enhances the cleaning effect. At the same time, when the scraper 62 rotates, some of the scraped dirt mixed with water splashes and collides with the scraper 62. After being intercepted by the scraper 62, the dirt mixed with water moves towards the bottom of the reactor under the guidance of the guide groove 63, which prevents the dirt from splashing onto the already scraped inner wall after being removed, thus affecting the cleaning effect. When disassembling, the equipment can be separated from the reactor by rotating the screw 43 in the opposite direction.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
