Description

Technical Field

[0001] This utility model relates to the field of reaction vessel equipment technology, specifically a reaction vessel that is easy to clean. Background Technology

[0002] A reaction vessel is a comprehensive reaction container consisting of a vessel body, a vessel lid, a stirrer, and other components. It can precisely control reaction conditions such as temperature, pressure, and stirring speed to achieve various physical and chemical reactions such as synthesis and decomposition. It is widely used in many fields such as chemical industry, pharmaceutical industry, and food industry, and can make reactants fully mixed and react uniformly.

[0003] Existing Chinese patent document CN220803202U discloses a reaction vessel that is easy to clean, comprising a stainless steel vessel body; a self-cleaning vessel lid is snapped onto the top of the stainless steel vessel body, a drive motor is mounted on the top of the self-cleaning vessel lid, a drive gear is connected to the drive shaft at the bottom of the drive motor, a central shaft is rotatably connected to the middle of the self-cleaning vessel lid, and a limit rod is slidably connected to the outer bottom of the self-cleaning vessel lid; this easy-to-clean reaction vessel uses a high-pressure nozzle installed on one side of the water distribution pipe, and when the drive motor drives the central shaft to rotate through the drive gear and rack belt, cleaning liquid is sprayed from the high-pressure nozzle on one side of the water distribution pipe. The nozzle sprays the residue onto the inner wall of the stainless steel vessel, and a stainless steel scraper on one side of the nozzle scrapes away the residue that has been soaked on the inner wall of the stainless steel vessel. However, this easy-to-clean reactor still has shortcomings: reactors are generally equipped with a stirring mechanism to ensure sufficient reaction, but the rotating scraper mechanism inside this equipment may interfere with the stirring mechanism and cannot be used synchronously. Moreover, the scraper and its connecting structure are fixed and cannot be easily replaced. During long-term use, the scraper or rotating shaft itself is prone to wear or damage. The inability to replace the connection reduces the overall durability of the equipment and affects the cleaning efficiency. Utility Model Content

A tension spring 19 is provided at the angle where the cleaning strip 1 13 and the cleaning strip 2 14 are connected.

[0025] Reference Figures 4 to 6 Four sets of main shaft slots 5 are symmetrically opened in four directions on the outer side of the bottom of the rotating shaft 4. When the two sets of connecting semi-ring plates 9 are hinged together and closed, they hold the connection between the rotating shaft 4 and the stirring shaft 6 or the cleaning shaft 7. Four sets of matching shaft slots 8 are symmetrically opened in four directions on the outer side of the top of the stirring shaft 6 and the cleaning shaft 7. The connecting block 10 is compatible with the specifications of the main shaft slots 5 and the matching shaft slots 8. There are eight sets of connecting blocks 10, which are symmetrically arranged inside the two sets of connecting semi-ring plates 9. The two sets of connecting semi-ring plates 9 are fixed in a tight state by the fixing buckle 11 at the end of one set being inserted into the preset fixing groove on the outer side of the other set.

[0026] The above scheme is adopted: four sets of main shaft slots 5 are symmetrically opened in four directions on the outer side of the bottom of the rotating shaft 4, and four sets of matching shaft slots 8 are also symmetrically opened in four directions on the outer side of the top of the stirring shaft 6 or cleaning shaft 7.

When the connecting half-ring pieces 9 are closed, the connecting blocks 10 are respectively inserted into the main shaft slots 5 and matching shaft slots 8. Then, the fixing buckle 11 at the end of one set of connecting half-ring pieces 9 is inserted into the fixed groove on the outer side of the other set, thereby holding the connection between the rotating shaft 4 and the stirring shaft 6 or cleaning shaft 7 tightly, and completing the connection between the two.

[0027] Reference Figure 4 Several sets of stirring blades 12 are symmetrically arranged on the outer side of the stirring shaft 6. The stirring blades 12 are all hinged to the corresponding parts on the outer side of the stirring shaft 6, and there is a certain friction at the connection so that the symmetrically arranged stirring blades 12 can be kept in a horizontally open state with the assistance of centrifugal force during rotation so as to carry out stirring and mixing operations.

[0028] Using the above scheme: the rotating shaft 4 drives the stirring shaft 6 to rotate synchronously, and several sets of stirring blades 12 are symmetrically arranged in four directions on the outside of the stirring shaft 6. With the assistance of friction at the connection with the stirring shaft 6 and centrifugal force during rotation, they are kept in a horizontally open state to stir and mix the materials in the reactor body 1.

[0029] Reference Figure 6 The cleaning strips 13, 14, and 15 are hinged together to form a movable trapezoidal support with the cleaning shaft 7 itself. Each of the cleaning strips 13, 14, and 15 has a brush structure for cleaning on the side facing the inner wall of the reactor body 1. The collar 16 at the end of the cleaning strip 15 is movably sleeved on the outside of the cleaning shaft 7 and engaged between the bottom limiting ring 17 and the top limiting ring 18. There are two sets of each of the cleaning strips 13, 14, and 15 symmetrically arranged on both sides of the cleaning shaft 7. At the angle between the two sets of cleaning strips 14 and 15, there is a tension spring 19 structure for elastically supporting the cleaning strips 14 and 15.

[0030] The above scheme is adopted: cleaning strip 13, cleaning strip 24, and cleaning strip 35 are hinged together to form a movable and extendable trapezoidal support with the cleaning shaft 7 itself, and each of them is provided with a bristle structure on the side facing the inner wall of the reactor body 1. The collar 16 hinged at the end of cleaning strip 35 is movably sleeved on the outside of the cleaning shaft 7 and engaged between the limiting bottom ring 17 and the limiting top ring 18. By adjusting the screw position of the limiting top ring 18 on the outside of the cleaning shaft 7, the cleaning strip 13, cleaning strip 24, and cleaning strip 35 can be adjusted. The trapezoidal support composed of three strips 15 extends to a convenient position for cleaning. The drive motor 3 starts, causing the cleaning shaft 7 to rotate. Cleaning strips 13, 24, and 35 rotate with the cleaning shaft 7, cleaning the inner wall of the reactor body 1. The tension spring 19 set at the angle between the two sets of cleaning strips 24 and 315 provides elastic support for cleaning strips 24 and 315, ensuring that the bristle structure can fit tightly against the inner wall of the reactor body 1, improving the cleaning effect.

[0031] Reference Figure 2 and Figure 3 A mounting lug 20 is fixed to the bottom of the outer side of the drive motor 3. A mounting hole 21 is opened through one end of the mounting tube 2. A mounting bolt 22 structure for fixing the drive motor 3 and the mounting tube 2 passes through the mounting lug 20. The mounting bolt 22 passes through the mounting lug 20 and the mounting hole 21 and is screwed into the matching nut structure.

[0032] Using the above scheme: the bottom outer side of the drive motor 3 is fixedly connected to the mounting tube plate 2 by mounting lug 20 and mounting bolt 22.

[0033] Reference Figure 1 The reactor body 1 is connected to the top of the feed pipe 23 and the bottom of the reactor body 1 is connected to the discharge pipe 24. One end of the discharge pipe 24 is equipped with a control valve 25 to control whether the contents are discharged.

[0034] Using the above scheme: the material enters the reactor body 1 through the feed pipe 23 connected at the top. After the reaction or cleaning is completed, the control valve 25 set at one end of the discharge pipe 24 is opened, and the material in the reactor body 1 is discharged through the discharge pipe 24 connected at the bottom. After cleaning is completed, the cleaning wastewater can also be discharged through the discharge pipe 24.

[0035] The working principle of this utility model is as follows: During use, the material enters the reactor body 1 through the feed pipe 23 connected at the top. The bottom outer side of the drive motor 3 is fixedly connected to the mounting tube plate 2 through the mounting lug 20 and mounting bolt 22. When it is necessary to stir and mix the reaction material, first connect the stirring shaft 6 to the rotating shaft 4. The bottom outer side of the rotating shaft 4 has four sets of main shaft slots 5 symmetrically opened in four directions, and the top outer side of the stirring shaft 6 also has four sets of matching shaft slots 8 symmetrically opened in four directions. The two sets of connecting semi-ring plates 9 are hinged to each other and symmetrically arranged. Eight sets of connecting blocks 10 are fixedly connected to the inner side. Close the connecting semi-ring plates 9 so that the connecting blocks 10 are respectively inserted into the main shaft slots 5 and matching shaft slots 8. Then, through... One set of fixing buckles 11 at the end of the connecting semi-ring 9 is engaged with the pre-set fixing groove on the outer side of the other set of ends, thereby securing the connection between the rotating shaft 4 and the stirring shaft 6, completing the connection between the two. The drive motor 3 starts, and its output end drives the rotating shaft 4 to rotate. The rotating shaft 4 drives the stirring shaft 6 to rotate synchronously. Several sets of stirring blades 12, symmetrically arranged in four directions on the outer side of the stirring shaft 6, are kept in a horizontally open state with the assistance of friction at the connection with the stirring shaft 6 and centrifugal force during rotation, to stir and mix the materials in the reactor body 1. When the reaction is completed and the reactor body 1 needs to be cleaned, the stirring shaft 6 is replaced with a cleaning shaft 7. Similarly, the connecting semi-ring 9 and the connecting clip 10 are used to secure the connection. Block 10 is inserted into the main shaft slot 5 of the rotating shaft 4 and the matching shaft slot 8 at the top of the cleaning shaft 7, fixing the connection between the two. A cleaning strip 13 is hinged to the bottom outer side of the cleaning shaft 7. The cleaning strips 13, 24, and 35 are hinged together with the cleaning shaft 7 to form a movable trapezoidal support. Each of them has a bristle structure on the side facing the inner wall of the reactor body 1. The collar 16 hinged at the end of the cleaning strip 315 is movably sleeved on the outside of the cleaning shaft 7 and engaged between the bottom limiting ring 17 and the top limiting ring 18. By adjusting the screw position of the top limiting ring 18 on the outside of the cleaning shaft 7, the extension range of the trapezoidal support composed of the cleaning strips 13, 24, and 315 can be adjusted. The convenient cleaning structure allows for easy placement and removal of cleaning materials. The drive motor 3 starts, rotating the cleaning shaft 7. Cleaning strips 13, 14, and 15 rotate with the shaft 7, cleaning the inner wall of the reactor body 1. Tension springs 19, located at the angle between the two sets of cleaning strips 14 and 15, provide elastic support, ensuring the brush structure fits tightly against the inner wall of the reactor body 1, improving cleaning effectiveness. After the reaction or cleaning is complete, the control valve 25 at one end of the discharge pipe 24 is opened, allowing the material inside the reactor body 1 to be discharged through the bottom-connected discharge pipe 24. Cleaning wastewater can also be discharged through the discharge pipe 24 after cleaning.
