Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, and in particular to a pressure-resistant screw conveyor for a reactor. Background Technology

[0002] As a core piece of equipment for material mixing, reaction, and synthesis in industries such as chemical, pharmaceutical, and food, the reactor's supporting material conveying system directly affects production efficiency and product quality. Screw conveyors, with their advantages of compact structure, continuous conveying, and good sealing, have become commonly used for material feeding and discharging in reactors, enabling precise directional material transport. However, existing reactor screw conveyors often use a rigid connection between the screw and the drive motor, lacking an effective pressure-resistant buffering mechanism. When the pressure inside the reactor fluctuates, the high pressure is directly transmitted to the connection between the screw and the motor, causing stress concentration at the connection point. Long-term use can easily lead to screw bending, motor shaft wear, or even breakage, severely affecting the equipment's service life. Therefore, this utility model proposes a pressure-resistant screw conveyor for reactors. Utility Model Content

[0031] Furthermore, a set of support baffles 5 are provided inside the reactor body 1. A pressure sensor 10 is fixedly installed on one side of the support baffles 5, and the pressure sensor 10 is electrically connected to the motor 8 and the external control equipment. A screw rod 6 for conveying materials is movably installed between the support baffles 5, and a sealing ring is provided at the connection between the screw rod 6 and the support baffles 5. A connecting block 7 is fixedly installed at one end of the screw rod 6, and a limiting pressure block 11 is fixedly installed at the other end of the screw rod 6. The limiting pressure block 11 can apply pressure to the pressure sensor 10 through the drive of the screw rod 6, thereby monitoring the pressure of the screw rod 6. Multiple threaded grooves 12 are opened on the outer wall of the connecting block 7.

[0032] Secondly, a guide rod 14 is fixedly installed at one end of the connecting block 7, and a motor 8 is fixedly installed at one end of the conveying pipe 2, which can provide power to the screw rod 6 through the motor 8.

[0033] like Figure 4 and Figure 5As shown, a pressure-resistant assembly for buffering the screw rod is arranged between the screw rod 6 and the motor 8, the pressure-resistant assembly comprises a sleeve block 91 sleeved at one end of the connecting block 7, which can ensure that the sleeve block 91 drives the screw rod 6 to stably rotate between the support baffles 5 through the connecting block 7, a plurality of threaded bolts 13 are arranged through the outer wall of the sleeve block 91 in a threaded manner, and one end of each threaded bolt 13 can be in threaded connection with the threaded groove 12, so that the connecting block 7 and the sleeve block 91 can be stably limited, one end of the sleeve block 91 is fixedly provided with a plurality of sliding rods 92, the sliding rods 92 are arranged in a "convex" shape, one end of each sliding rod 92 is fixedly provided with a collar 93, and the collar 93 is movably sleeved with the linkage block 94, which can limit the sliding rod 92.

[0034] Further, the pressure-resistant assembly further comprises a linkage block 94 fixedly arranged at one end of the motor 8, one end of the linkage block 94 is provided with a guide groove 15, the guide rod 14 is slidably connected with the guide groove 15, which can guide the linkage block 94 to make its movement more stable, the outer wall of the linkage block 94 is provided with a plurality of sliding grooves 95, and the sliding grooves 95 are arranged in a "convex" shape, which can make the sliding grooves 95 stably slidably connected with the collar 93, one end of the linkage block 94 is fixedly provided with a sleeve ring 96, the other end of the linkage block 94 is fixedly provided with a limit collar 97, the limit collar 97 can limit the collar 93, a spring 98 is sleeved between the collar 93 and the linkage block 94, one end of the spring 98 is fixedly connected with the sleeve block 91, the other end of the spring 98 is fixedly connected with the sleeve ring 96, and the spring 98 can provide buffering for the screw rod 6 through its own elastic force, so as to increase the pressure resistance effect.

[0036] During the material conveying process, the reaction force generated by the screw rod 6 pushing the material drives the screw rod 6 to move, the screw rod 6 drives the sleeve block 91 to move through the connecting block 7, and the sleeve block 91 drives the sliding rod 92 to slide inside the sliding groove 95. At the same time, the sleeve block 91 exerts pressure on the spring 98, the spring 98 absorbs pressure impact through its own telescopic deformation, and the collar 93 slides synchronously along the sliding groove 95, which effectively offsets the impact force caused by pressure fluctuation, avoids stress concentration at the connecting part, and prevents the screw rod from bending, or the shaft of the motor 8 from wearing or breaking.

[0037] Next, the other end of the screw rod 6 drives the limiting block 11 to move. The limiting block 11 applies pressure to the pressure sensor 10 on the support baffle 5. The pressure sensor 10 monitors the pressure change of the screw rod 6 in real time and transmits the data to the control equipment. When the pressure is too high, the motor 8 is controlled to avoid the risk of impact and ensure continuous and reliable material conveying.

[0038] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
