Description

Technical Field

[0001] The utility model relates to the technical field of chemical reaction kettles, and specifically relates to a feeding device for a chemical reaction kettle. Background Technique

[0002] A chemical reaction kettle is a device used for carrying out chemical reactions, usually used in industrial production. It is a sealed container in which reaction conditions such as temperature, pressure, and stirring can be controlled. Chemical reaction kettles are usually made of corrosion-resistant materials to handle various chemical substances. Chemical reaction kettles are widely used in the fields of pharmaceuticals, chemical industry, petroleum refining, food processing, etc.

[0003] When granular reaction materials are put into the interior of the reaction kettle, some granular reaction materials are prone to agglomeration. If these granular reaction materials containing agglomeration are directly put into the interior of the reaction kettle, the surface area of the reaction materials will be reduced by the agglomerated granular reaction materials, resulting in a reduction in the contact area between the reaction materials and the reaction medium, and it takes a longer time to have an effective reaction, thereby reducing the reaction rate and possibly affecting the reaction result. At present, generally, the staff pre-disperse and grind the agglomerated granular reaction materials in advance and then put them into the reaction kettle, which undoubtedly brings trouble to the staff. In order to solve this problem, we propose a feeding device for a chemical reaction kettle. Content of the Utility Model

[0019] Please refer to Figures 2 - 4 , a plurality of spikes 16 are fixedly connected to the outer wall of the rotating column 15 shown in the figure. The plurality of spikes 16 and the rotating column 15 are of an integrally formed structure; the stability between the plurality of spikes 16 and the rotating column 15 is good.

[0020] Please refer to Figure 3 , the linkage mechanism shown in the figure includes a first bevel gear 13 and a second bevel gear 14. The first bevel gear 13 is fixedly connected to one end of the connecting column 7 close to the rotating column 8, the second bevel gear 14 is fixedly connected to the upper end of the rotating column 8, the first bevel gear 13 and the second bevel gear 14 are meshed with each other, and a covering member is provided between the connecting column 7, the rotating column 8 and the feeding hopper 3.

[0021] Please refer to Figure 2 and Figure 3 , the covering member shown in the figure includes a circular shell 9. The circular shell 9 is located outside the first bevel gear 13 and the second bevel gear 14. The rotating column 8 and the connecting column 7 are both rotatably installed through the inner wall of the circular shell 9. A fixing member is provided between the circular shell 9 and the feeding hopper 3; by providing the circular shell 9, the first bevel gear 13 and the second bevel gear 14 can be covered.

[0022] Please refer to Figure 2 and Figure 3, the fixing members in the illustration include two fixing rods 10, which are symmetrically and fixedly connected to the outer wall of the circular shell 9, and the ends of the two fixing rods 10 away from each other are fixedly connected to the inner wall of the feeding hopper 3 near the upper edge; by arranging the two fixing rods 10, the circular shell 9 can be made more stable.

[0023] Please refer to Figures 1 - 3 , the driving mechanism in the illustration includes an L-shaped plate 6, which is fixedly connected to the outer wall of the feeding hopper 3, and a motor 5 is fixedly connected to the upper end of the L-shaped plate 6, and the rotating shaft end of the motor 5 is fixedly connected to the end of the connecting column 7 away from the rotating column 8.

[0024] Working principle: When using this device to input granular reaction materials with agglomerates, first connect the motor 5 to an external power source. The rotating shaft end of the motor 5 can drive the connecting column 7 to rotate synchronously. The connecting column 7 can drive the first bevel gear 13 to rotate. The first bevel gear 13 can drive the second bevel gear 14 to rotate. The second bevel gear 14 can drive the rotating column 8 to rotate. The rotating column 8 can drive the two cylinders 12 and the two inclined plates 11 to rotate synchronously. The two cylinders 12 can drive the rotating column 15 and the spikes 16 to rotate synchronously; then open the hopper cover 4, and then input the granular reaction materials with agglomerates into the feeding hopper 3. The reaction materials will slide along the feeding hopper 3 into the interior of the feed pipe 2. At this time, the granular reaction materials with agglomerates will slide onto the upper end of the filter screen 17. The unagglomerated granular reaction materials will slide through the pores of the filter screen 17 into the interior of the kettle body 1. Subsequently, the granular reaction materials with agglomerates will get stuck on the upper end of the filter screen 17 and will not fall. Then the rotation of the rotating column 15 and the spikes 16 will hit the granular reaction materials with agglomerates. At this time, the spikes 16 can break the granular reaction materials with agglomerates into small fragments. During the rotation of the two inclined plates 11, the angle between the inclined plates 11 and the filter screen 17 will press on these granular reaction materials in small fragments. Then, with the rotation of the inclined plates 11, these granular reaction materials in small fragments will be crushed by the inclined plates 11. With the continuous rotation of the inclined plates 11, the rotating column 15 and the spikes 16, the granular reaction materials with agglomerates can be broken, and finally the crushed granular reaction materials can fall through the filter screen 17 into the interior of the kettle body 1.

[0025] It should be noted that when using this device to input granular reaction materials with agglomerates, the granular reaction materials with agglomerates can be dispersed and crushed before being input into the kettle body 1, increasing the contact area between the granular reaction materials with agglomerates and the reaction medium, improving the reaction rate, and eliminating the need for manual pre-dispersion and grinding, which brings certain convenience to the staff.
