Description

Technical Field

[0001] This utility model relates to the technical field of reactor feeding devices, and in particular to a reactor feeding device. Background Technology

[0002] In chemical production processes, the feeding device of a reactor is a critical piece of equipment affecting production efficiency and operational safety. Traditional reactor feeding devices mostly use fixed inlets, which have low positioning accuracy and insufficient sealing. Especially under high temperature and high pressure conditions, sealing failure during feeding can easily lead to internal gas or material leakage, resulting in energy waste and potential safety hazards. Furthermore, existing devices lack flexible positioning adjustment functions, making it difficult to adapt to changes in the position of the feeding inlet in different reactors. Manual adjustment or shutdown for calibration is often required, severely impacting the efficiency of continuous production. Although some improvement solutions attempt to introduce movable feeding structures, these often rely on complex external drive mechanisms, resulting in bulky equipment, cumbersome operation, and gaps still exist in the dynamic fit between the sealing cover and the feeding inlet, failing to effectively isolate internal pressure fluctuations.

[0003] Therefore, we propose a reactor feeding device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a reactor feeding device. When using this device, a sliding positioning block and a positioning screw linkage mechanism are used to achieve rapid and accurate alignment between the feed inlet and the reactor feeding port, significantly improving feeding efficiency. The high-temperature resistant hose and electric push rod work together to ensure the sealing cover dynamically fits the feeding port during feeding, effectively preventing leakage of internal high-pressure gas and ensuring operational safety. The integrated design of the lower pressure block and conveying pipe, combined with the spring rod structure of the lifting cover, automatically opens the cover and completes material conveying during feeding, simplifying the operation process and avoiding material waste caused by multiple adjustments in traditional devices. The overall structure is compact, requiring no complex drive components, reducing manufacturing costs and improving the reliability and adaptability of the equipment, thus solving the problems mentioned in the background art.

[0016] 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.

[0017] Please see Figure 1-4A reactor feeding device includes a reactor body 1, a positioning platform 2 fixedly installed on the upper end of the reactor body 1, a slot 3 is opened on the surface of the positioning platform 2, a positioning block 4 is slidably embedded in the inner wall of the slot 3, the upper end of the positioning block 4 is connected to the feed inlet 5, a conveyor 6 is installed on the upper end of the feed inlet 5 for conveying materials, and sliding grooves 15 are provided on both sides of the positioning block 4, a positioning screw 13 is installed in the inner wall of the sliding groove 15, the positioning screw 13 is connected to the inside of the positioning block 4 by threads, and by rotating the positioning screw 13, the positioning block 4 can move laterally along the slot 3, thereby accurately adjusting the alignment of the feed inlet 5 with the feeding port 14 at the upper end of the reactor body 1; The bottom end of the positioning block 4 is fixedly connected to the high-temperature resistant hose 7. The high-temperature resistant hose 7 is made of flexible high-temperature resistant material and can adapt to the high-temperature environment inside the reactor. The inner wall of the high-temperature resistant hose 7 is fixedly installed with the pressure block 10. The two sides of the pressure block 10 are symmetrically connected with the conveying pipe 11. The upper end of the conveying pipe 11 passes through the hollow inner wall of the positioning block 4 and is connected to the feed port 5. The bottom end of the high-temperature resistant hose 7 is fixed with the sealing cover 8. The upper end of the sealing cover 8 is installed with the electric push rod 9. The top end of the electric push rod 9 is fixed on the lower surface of the positioning block 4. When the positioning block 4 moves to the target position, the electric push rod 9 is activated and pushes the sealing cover 8 vertically downward to make it tightly fit the feed port 14 of the reactor body 1, forming a dynamic seal and effectively isolating the leakage of internal high-pressure gas. A lifting cover 12 is installed on the inner wall of the feeding port 14. The size of the lifting cover 12 is slightly larger than that of the feeding port 14. Its two sides are connected to the inner wall of the feeding port 14 through spring rods. The lower pressure block 10 has an electric push rod built in. When feeding, the electric push rod drives the lower pressure block 10 to move downward, which drives the conveying pipe 11 to move downward synchronously. After the bottom end of the conveying pipe 11 contacts the lifting cover 12, the spring rod is compressed and retracts, and the lifting cover 12 opens accordingly. The conveying pipe 11 extends into the reactor through the opening. At this time, the conveyor 6 starts, and the material is directly conveyed to the reactor through the feed port 5 and the conveying pipe 11. No manual intervention is required throughout the process. After feeding is completed, the electric push rod of the lower pressure block 10 resets, the feeding pipe 11 rises, and the lifting cover 12 automatically closes under the elastic force of the spring rod. The electric push rod 9 then drives the sealing cover 8 to disengage from the feeding port 14, completing a single feeding cycle. The high-temperature resistant hose 7 flexibly deforms during the extension and retraction of the electric push rod 9 to ensure the dynamic fit between the sealing cover 8 and the feeding port 14. The precise adjustment function of the positioning screw 13 combined with the automatic control of the electric push rod 9 achieves both rapid positioning and reliable sealing.

[0018] The main body 1 of this utility model is the main base of the entire device. During use, all the devices are arranged around the main body 1. A crushing cylinder 2 is provided at the upper end of the main body 1. Two sets of crushing rollers 5 are provided inside the crushing cylinder 2. The upper crushing roller 5 crushes the larger pieces of heparin sodium into smaller pieces, which then fall to the lower crushing roller 5 for further crushing into even smaller pieces. At the upper end of the crushing cylinder 2 is a connecting cylinder 3, which is used to connect to the feeding cylinder 4. After the heparin sodium is poured in from the opening at the upper end, it will slide on the inner wall of the feeding cylinder 4. The inner wall is provided with a heating inner wall 6. The heparin sodium is dried by sliding. A drain 7 is provided at one end of the heating inner wall 6 to recover the undried water into the lower outer pipe 8 to prevent it from accumulating there. After the sodium heparin falls, it will be crushed in the crushing cylinder 2 through the connecting cylinder 3, and then fall to the discharge port 9 set on the inner wall of the main body 1, where it will be recycled by the receiving plate 10.
