[0018] Now, the present utility model will be further described in detail with reference to the drawings. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0019] Such as Figure 1It is a schematic structural diagram of the present utility model. A dropping and feeding device for a reaction kettle includes a dropping and feeding pipe 1 and a feeding replenishment tank 2.

[0020] The feeding replenishment tank 2 is used to accommodate the spare raw materials. The feeding replenishment tank 2 is fixedly connected to the top surface of the reaction kettle 3, and the feeding replenishment tank 2 is located outside the reaction kettle 3.

[0021] As Figure 1 、 Figure 2 shown, the dropping and feeding pipe 1 is used to accommodate the raw materials and drop the raw materials into the reaction kettle 3. The upper part of the dropping and feeding pipe 1 has a feeding replenishment pipe 11. The tail end of the feeding replenishment pipe 11 extends into the feeding replenishment tank 2 and extends to the bottom inside the feeding replenishment tank 2, so that a constant pressure area 12 is formed inside the dropping and feeding pipe 1. The bottom surface of the dropping and feeding pipe 1 has a dropping pipe 13. The tail end of the dropping pipe 13 extends into the reaction kettle 3. Through the feeding replenishment tank 2 and the design of the pressure in the constant pressure area 12 inside the dropping and feeding pipe 1, the raw materials are attracted into the dropping and feeding pipe 1 through the feeding replenishment pipe 11, realizing automatic feeding replenishment, and can also maintain the raw material storage in the dropping and feeding pipe 1, so that the pressure inside it remains constant, facilitating the accurate dropping of raw materials.

[0022] An inlet 14 is opened on the top surface of the dropping and feeding pipe 1. A sealing plug 15 is arranged in the inlet 14. Thus, the initial raw materials are added into the dropping and feeding pipe 1, and the initial pressure inside the dropping and feeding pipe 1 can be controlled according to the raw materials inside the dropping and feeding pipe 1. After the addition of the raw materials is completed, the dropping and feeding pipe 1 is closed through the sealing plug 15. On the one hand, it is to prevent impurities from entering the dropping and feeding pipe 1, and on the other hand, it is used to maintain the constant pressure of the dropping and feeding pipe 1.

[0023] As Figure 2 shown, a regulating valve 16 is arranged between the dropping and feeding pipe 1 and the dropping pipe 13. The regulating valve 16 is used to control the dropping speed of the dropping and feeding pipe 1. The dropping speed is controlled by rotating the regulating valve 16.

[0024] The dropping and feeding pipe 1 is fixedly connected to the feeding replenishment tank 2 through a fixed bracket, increasing the installation stability of the dropping and feeding pipe 1, so as to ensure the constant-speed dropping of raw materials by the dropping and feeding pipe 1.

[0025] As Figure 2 shown, the dropping and feeding device further includes an adjusting pipe 17. The adjusting pipe 17 is threadedly connected to the dropping pipe 13, and the adjusting pipe 17 is located outside the dropping pipe 13. The adjusting pipe 17 is used to control the depth of the dropped raw materials. The adjusting pipe 17 extends into the reaction kettle 3. For the production requirements of different products, the requirements for the dropping of corresponding raw materials are different. Thus, the raw materials are dropped above or into the slurry in the reaction kettle 3 through the adjusting pipe 13.

[0026] As Figure 2As shown in the figure, the regulating pipe 17 is rotatably connected to the reaction kettle 3 through the collar 18, and the collar 18 is fixedly connected to the reaction kettle 3 to increase the stability of the regulating pipe 17. The connection between the feeding pipe 11 and the dropping feeding pipe 1 is communicated with the constant pressure area 12.

[0027] Since the inside of the dropping feeding pipe 1 is a constant pressure environment, the raw materials in the feeding tank 2 are sucked into the dropping feeding pipe 1 by using the pressure compensation mechanism to maintain the constant pressure.

[0028] Inspired by the ideal embodiments of the present invention described above, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
