Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically to an apparatus for one-pot synthesis of foaming agents. Background Technology

[0002] Foaming agent (4,4'-oxobisbenzenesulfonyl hydrazine) is an organic compound whose molecular structure consists of two benzene rings connected by oxygen atoms, with one sulfonyl group and one hydrazine group on each benzene ring. It appears as a white or slightly yellow crystalline powder. As a multifunctional organic compound, it has broad application prospects in many fields such as pharmaceuticals, dyes, and polymers. Currently, the synthesis of 4,4'-oxobisbenzenesulfonyl hydrazine requires the use of a reaction vessel.

[0003] The existing patent publication number CN216778795U discloses a reaction vessel that is easy to clean, belonging to the field of reaction vessel technology. It includes: a tank body, a feed inlet, a first motor, a rotating rod, a first stirring blade, a second motor, a water spray unit, a water spray nozzle, a water pipe, and a liquid outlet. This device provides a reaction vessel that is easy to clean. Water is injected into the water spray unit through the water pipe, the second motor operates, and the second output shaft drives the water spray unit to rotate, thereby spraying water around the inner wall of the tank to clean it and prevent residual substances from remaining on the inner wall, which would make the reaction vessel unusable and affect production quality. However, during use, the cleaning nozzles inside this easy-to-clean reaction vessel are fixed in position and cannot be moved, which can lead to incomplete cleaning of certain parts inside the vessel. Therefore, we propose a device for one-pot synthesis of foaming agents to solve the above problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 and Figure 3As shown in the figure, an embodiment of this utility model discloses an apparatus for one-pot synthesis of a foaming agent, comprising a reactor body 1. A mounting frame 17 is fixed to an opening on the front of the reactor body 1. A transparent plate 18 is fixed inside the mounting frame 17, making it easier for operators to inspect the interior of the reactor body 1 from the outside. A reactor lid 2 is mounted on the top of the reactor body 1. The top of the reactor lid 2 is rotatably connected to a rotating shaft 3 and two lead screws 5 via bearings. Both lead screws 5 are made of stainless steel. Because the foaming agent (4,4'-oxobis(benzenesulfonylhydrazine)) has certain... Corrosive, the lead screw 5 is made of stainless steel, thus extending its service life. Blades 4 are equidistantly fixed to the surface of the rotating shaft 3. Hollow annular plates 6 are threadedly connected to the surfaces of the two lead screws 5. Spray nozzles 7 for cleaning the inner wall of the vessel body 1 are fixedly connected in a ring array on the surface of the hollow annular plates 6. A hose 8 is fixedly connected to the water inlet of the hollow annular plates 6. The other end of the hose 8 slides through the vessel body 1 and extends to its outside. An elastic reset component 9 is provided on the outer wall of the vessel body 1 to automatically reset the hose 8 after cleaning and stretching. The surface of the rotating shaft 3 is fixed with… The scraper frame 10, used in conjunction with the nozzle 7, has an inlet pipe 11 and an outlet pipe 12 fixedly connected to the outer wall of the reactor body 1. A cover plate 13 is hinged to the inlet pipe 11, and a valve is installed on the outlet pipe 12. When using this apparatus for one-pot synthesis of foaming agents, after 4,4'-oxobisbenzenesulfonyl is fed into the reactor body 1, the motor is started to drive the rotating shaft 3 to rotate, thereby stirring and synthesizing the raw materials. After the synthesis is completed, when it is necessary to clean the inside of the reactor body 1, one end of the hose 8 is connected and fixed to the water supply pipe, and the cleaning water is sent into the hollow annular plate 6 for cleaning. Water is sprayed out through the annular array of nozzles 7. The motor is started to drive the lead screw 5 to rotate. After the lead screw 5 rotates, it will drive the hollow annular plate 6 to move up and down. At this time, the cleaning water sprayed from the nozzles 7 will be evenly sprayed to the inner wall of the vessel 1 to rinse it. At the same time, the motor can also be started to drive the rotating shaft 3 to rotate. After the rotating shaft 3 rotates, it will drive the scraper frame 10 to clean the inner wall of the vessel 1. Therefore, the inner wall of the vessel 1 can be cleaned more thoroughly. At the same time, this reactor has the function of heating and temperature control. Since it is existing technology, it is not described in detail here.

[0025] like Figure 2 and Figure 4As shown, in some embodiments, the elastic reset assembly 9 includes two connecting plates 901 fixed to the outer wall of the vessel body 1. The hose 8 slides through the two connecting plates 901. A guide rod 902 is fixed between the two connecting plates 901. A moving plate 903 is slidably connected to the surface of the guide rod 902. The hose 8 is fixedly connected to the moving plate 903. A spring 904 is fixed to the top of the moving plate 903. The top of the spring 904 is fixedly connected to the upper connecting plate 901. In use, when the hollow annular plate 6 moves one end of the hose 8 downward, the hose 8 will move and bring... When the movable plate 903 moves upward, it will compress the spring 904. When the hollow annular plate 6 drives the hose 8 to move upward, the stretched hose 8 can automatically reset under the reset force of the compressed spring 904. Thus, when the vessel 1 is being cleaned, the hose 8 will always be in a vertical state when it moves up and down inside, avoiding interference with the blade 4 after bending. The movable plate 903 is limited to slide on the surface of the guide rod 902, so when the movable plate 903 moves, it can only move up and down and will not rotate left and right.

[0026] like Figure 1 As shown, in some embodiments, sprockets 14 are fixed on the surface of the lead screw 5. The two sprockets 14 are connected by a chain 15, so that the two lead screws 5 can be driven to rotate simultaneously under the action of a motor, thereby saving production costs.

[0027] like Figure 3 As shown, in some embodiments, two rubber strips 16 are fixed to the surface of the scraper frame 10. The rubber strips 16 are tightly attached to the inner wall of the vessel body 1. By using the rubber strips 16, the tightness of the attachment between the scraper frame 10 and the inner wall of the vessel body 1 can be enhanced, thereby enhancing the cleaning effect inside the vessel body 1.

[0028] 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 utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
