Detailed Implementation
[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.
[0031] Reference Figures 1-4 A chemical raw material feeding device for a reaction vessel includes a storage bin 1, a discharge pipe 2 fixedly connected to the bottom of the storage bin 1, a metering feeder 3 fixedly connected to the bottom of the discharge pipe 2, a conveying pipe 4 fixedly connected to the bottom of the metering feeder 3, a reaction vessel 5 fixedly connected to the bottom of the conveying pipe 4, a cover plate 10 threadedly installed on the top of the storage bin 1, a bracket 12 fixedly installed on the top of the cover plate 10, a motor 13 fixedly installed on the top of the bracket 12, a lead screw 14 fixedly connected to the power output shaft of the motor 13, a slider 15 threadedly connected to the outer edge of the lead screw 14, side plates 16 symmetrically installed on both sides of the slider 15, and sliding rods 17 fixedly connected to the bottom of both side plates 16, and push rings 18 fixedly connected to the bottom of both sliding rods 17.
[0032] See Figure 1 and Figure 3 An observation window 11 is fixedly installed on the inner wall of the cover plate 10, so that users can see the condition inside the storage bin 1 without opening the cover plate 10.
[0033] See Figure 2 and Figure 3 An electric butterfly valve 6 is installed on the inner wall of the feed pipe 2, which can be used to control the opening and closing of the inner wall of the feed pipe 2.
[0034] See Figure 2 A filter screen 7 is fixedly installed on the inner wall of the conveying pipeline 4. A flow meter 8 and a pressure sensor 9 are also installed on the inner wall of the conveying pipeline 4. The filter screen 7 can be used to prevent foreign objects from entering the reactor 5 and protect the production equipment. The flow meter 8 and the pressure sensor 9 can be used to detect the state of the material and then dynamically adjust the working state of the quantitative feeder 3 according to the real-time data to ensure the uniformity and stability of the feeding process.
[0035] See Figure 1 The top of the cover plate 10 is fixedly connected to a feeding pipe 19, which can be used to guide and discharge materials into the inner cavity of the storage bin 1.
[0036] See Figure 3 and Figure 4Two sliding rods 17 are slidably connected to the inner wall of the cover plate 10, and the push ring 18 is slidably connected to the inner wall of the storage bin 1. The outer edge of the push ring 18 is in contact with the inner wall of the storage bin 1, so that the movement of the slider 15 can drive the two sliding rods 17 to move up and down on the inner wall of the cover plate 10, and then drive the push ring 18 to move down against the inner wall of the storage bin 1, thereby pushing the material adhering to the inner wall of the storage bin 1 to move down, ensuring the thoroughness of material discharge.
[0037] See Figure 3 and Figure 4 A ring is fixedly installed on the inner bottom of the bracket 12. The bottom end of the lead screw 14 is rotatably connected to the inner wall of the ring. The slider 15 is adapted to slide and connect to the inner wall of the bracket 12, so that it can be used to position the lead screw 14 during the rotation process, ensuring the stability of the lead screw 14 during rotation, ensuring that it will not easily shift or swing in position during rotation, and ensuring that the slider 15 can move stably up and down on the inner wall of the bracket 12.
[0038] Working Principle: First, open the electric butterfly valve 6 at the bottom of the storage silo 1, allowing the raw material to flow into the quantitative feeder 3 through the discharge pipe 2. The motor of the quantitative feeder 3 starts running, and the flow rate of the raw material is controlled by adjusting the speed. After the raw material enters the conveying pipeline 4, it is detected by the flow meter 8 and the pressure sensor 9. Based on the real-time data, the working state of the quantitative feeder 3 is dynamically adjusted to ensure uniform and stable feeding. Finally, the raw material is successfully conveyed into the reaction vessel 5. After reaching the predetermined weight, the system automatically stops running. During the feeding process, the drive motor 13 drives the lead screw 14 to rotate, which in turn drives the slider 15 to move up and down. This, in turn, pushes the push ring 18 against the inner wall of the storage silo 1 downward through the two side plates 16 and the two sliding rods 17, thus pushing the material adhering to the inner wall of the storage silo 1 downward, ensuring thorough feeding and avoiding material residue.
