Description

Technical Field

[0001] This utility model belongs to the technical field of organosilicon production, specifically relating to a liquid organosilicon distillation apparatus. Background Technology

[0002] Organosilicon compounds are compounds containing Si-C bonds, with at least one organic group directly bonded to a silicon atom. Conventionally, compounds in which organic groups are bonded to silicon atoms via oxygen, sulfur, nitrogen, or other means are also considered organosilicon compounds. Organosilicon is a commonly used liquid substance in manufacturing, and its production requires a distillation process.

[0003] A search revealed that CN216295247U discloses an organosilicon liquid distillation apparatus, including a heating chamber, a feed inlet, and a base. The feed inlet is located above the heating chamber, and a finished product box is located on the side of the distillation chamber. A mounting frame is installed between the distillation chamber and the finished product box. A condenser tube is fixedly connected to both sides of the distillation chamber and the finished product box, respectively. Because existing organosilicon liquid distillation apparatuses do not heat organosilicon evenly, some raw materials tend to remain at the bottom of the distillation chamber during distillation. This organosilicon liquid distillation apparatus uses a guide plate that swings up and down to transport the raw material uniformly downward through the inclined openings on both sides. The guide plate inside the discharge port is configured with two plates arranged one above the other. When the guide plate rotates, it drives the rotating rods that are arranged crosswise between them to rotate. The rotating rods stir the raw material in the discharge port, making the stirring more uniform during heating and improving the heating efficiency of the raw material, thus increasing the production efficiency of the raw material.

[0004] However, the above-mentioned organosilicon liquid distillation device technology still has the following problems: the distillation process of the above-mentioned organosilicon liquid distillation device needs to be completed in the heating box, distillation box and finished product box. The split design leads to a complex layout of the equipment, which does not meet the practical needs of modern miniaturization and integration. Utility Model Content

[0005] The purpose of this invention is to provide a liquid organosilicon distillation device to solve the problem of complex equipment layout caused by the split design mentioned in the background art.

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.

[0026] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a liquid organosilicon distillation device, including a tank 1 and a motor 2 fixed to the top surface of the tank 1. The tank 1 is provided with a preheating chamber 11, a heating chamber 12 located below the preheating chamber 11, a compression chamber 13 connecting the preheating chamber 11 and the heating chamber 12 vertically, and a collection chamber 14 located outside the compression chamber 13. A heating plate 6 is provided in the bottom cavity of the heating chamber 12. The output end of the tank 1 is connected to a stirring mechanism 3 that can stir the organosilicon raw materials in the preheating chamber 11 and the heating chamber 12. Several heat dissipation plates 5 are fixed on the outside of the tank 1 and distributed in a ring outside the collection chamber 14. A cooling plate group 4 is provided on one side of the tank 1 to pass the liquid condensed by the organosilicon vapor in the tank 1 through the heat dissipation plate 5 into the collection chamber 14.

[0027] Please see Figure 3 and Figure 4 The stirring mechanism 3 includes a main shaft 31, which is fixed to the output end of the motor 2. Several first stirring rods 32 are fixed on the main shaft 31 at the location of the preheating chamber 11, and several second stirring rods 33 are fixed on the main shaft 31 at the location of the heating chamber 12. When the motor 2 is working, the main shaft 31 can drive the first stirring rods 32 and the second stirring rods 33 to rotate in the preheating chamber 11 and the heating chamber 12 respectively, thereby enabling the organosilicon raw materials in the preheating chamber 11 and the heating chamber 12 to be fully heated, thereby improving the heat utilization efficiency.

[0028] Furthermore, a screw conveyor 34 is fixed at the location of the main shaft 31 within the extrusion chamber 13. The upper end of the screw conveyor 34 extends into the preheating chamber 11. During the rotation of the main shaft 31, the screw conveyor 34 can guide the organosilicon raw material at the bottom of the preheating chamber 11 from the extrusion chamber 13 into the heating chamber 12.

[0029] Furthermore, the main shaft 31 is fixed with an extrusion disc 35 at the top of the heating chamber 12. The extrusion disc 35 is conical and eccentrically positioned with the main shaft 31. During the process of the auger 34 guiding the silicone raw material from the bottom of the preheating chamber 11 from the extrusion chamber 13 into the heating chamber 12, the silicone raw material can be rotated and extruded by the eccentrically positioned extrusion disc 35, which further breaks down the granular raw material.

[0030] Please see Figure 1 and Figure 2 The cooling plate assembly 4 includes a spiral tube 41 that spirally penetrates the heat dissipation plate 5. The lower end of the spiral tube 41 is connected to the top cavity of the preheating chamber 11 through an external pipe 42, and the upper end of the spiral tube 41 is connected to the top cavity of the collection chamber 14 through an internal pipe 43. The discharged steam enters the spiral tube 41 through the external pipe 42. During the spiral conduction process in the spiral tube 41, the heat is transferred to the heat dissipation plate 5 and dissipated outward, thereby reducing the temperature and condensing into liquid and entering the collection chamber 14.

[0031] Furthermore, the external pipe 42 is equipped with a check valve 44 that allows steam in the preheating chamber 11 to flow unidirectionally into the collection chamber 14. This valve can prevent the condensate in the cooling plate assembly 4 from flowing out and also facilitates the use of the pressure in the preheating chamber 11 to guide the condensate into the collection chamber 14.

[0032] Furthermore, the top surface of the tank body 1 is provided with a feed inlet 15 leading to the preheating chamber 11 for introducing organosilicon raw materials. During the distillation process, the valve on the feed pipe of the feed inlet 15 is closed, so that the preheating chamber 11 is in a sealed environment.

[0033] Furthermore, a pressure relief valve 16 is provided on one side of the top of the collection chamber 14 to balance the air pressure inside the collection chamber 14.

[0034] Furthermore, a discharge valve 17 is provided on one side of the bottom of the collection chamber 14 for discharging the organosilicon liquid stored in the collection chamber 14.

[0035] Furthermore, a slag removal port 18 is provided on one side of the bottom of the heating chamber 12, which can be opened to clean the residue at the bottom of the heating chamber 12.

[0036] The working principle and usage process of this utility model are as follows: After the organosilicon raw material added to the feed port 15 enters the preheating chamber 11, it is stirred by the first stirring rod 32 and then spirally guided by the auger 34 to the extrusion chamber 13. When passing through the extrusion plate 35, the organosilicon raw material is rotated and extruded by the eccentrically set extrusion plate 35, which further breaks down the granular raw material. Then it enters the heating chamber 12 and is heated by the heating plate 6. The organosilicon raw material is fully heated by the rotation of the second stirring rod 33. The steam generated during the heating process enters the preheating chamber 11 through the extrusion chamber 13, which can preheat the organosilicon raw material in the preheating chamber 11 to improve thermal efficiency. The discharged steam enters the spiral tube 41 through the external pipe 42. During the spiral guidance process in the spiral tube 41, the heat is transferred to the heat dissipation plate 5 and dissipated outward, thereby reducing the temperature and condensing into liquid and entering the collection chamber 14 to realize the collection and storage of organosilicon liquid.
