The twin-screw inert powder conveying mechanism, as a key component of the explosion-proof dust collector, is used to safely and efficiently transport the collected inert powder to the designated location to prevent safety accidents such as explosions caused by powder leakage. It can stably convey powder in a relatively closed environment, ensuring the safety and continuity of the entire production process.

[0003] Existing twin-screw inert powder conveying mechanisms usually adopt a relatively fixed screw installation structure, which is generally fixed to the transmission device by welding, high-strength bolt connection or complex embedded structure. When the screw needs to be replaced due to long-term wear or other reasons, this fixing method will bring many inconveniences. The welding method makes the screw difficult to disassemble, requiring complex operations such as cutting, and is prone to damage to other components; and the high-strength bolt connection structure may cause the bolts to rust and become stuck after long-term operation, making disassembly extremely difficult. These traditional connection structures make the screw replacement process cumbersome, time-consuming and labor-intensive, seriously affecting production efficiency, increasing equipment maintenance costs, and even affecting the normal operation of the entire production system during long-term shutdowns for screw replacement.

Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Referring to Figure 1 , Figure 4 and Figure 5The utility model provides an embodiment: a twin-screw inert powder conveying mechanism for an explosion-proof dust collector, comprising a base 4, an upper surface of the base 4 is slidably connected to a shell 5, the shell 5 provides a relatively closed space for the entire conveying mechanism, effectively preventing dust leakage, ensuring the safety of the conveying process, and meeting explosion-proof requirements, the shell 5 is internally threaded with a screw 22, the outer wall of the screw 22 is threadedly connected to the inside of the base 4, and the shell 5 can be mounted on the upper surface of the base 4 by setting the screw 22, which is convenient for the subsequent installation of the screw 6, and the outer wall of the shell 5 is provided with a support component The support assembly includes a support frame 14. The outer wall of the support frame 14 is fixedly connected to the outer wall of the shell 5. Its main function is to provide a stable support platform for the motor 2 7 to ensure that the motor 2 7 does not shake or displace during operation, thereby ensuring the stability of power transmission. The upper surface of the support frame 14 is fixedly connected to the motor 2 7. The motor 2 7 serves as a driving source to provide power for the rotation of the screw 6. The inner part of the shell 5 is connected to the gear 15. The gear 15 cooperates with the screw 6 to realize the synchronous rotation of the twin screws 6 to ensure the smooth transportation of the material. The gear 15 is fixedly connected to the connecting rod 3 16. The connecting rod The third 16 serves to connect the gear 15 and the screw 6, and transmits the power of the motor 2 7 to the screw 6. A fixing assembly is provided inside the connecting rod 3 16, and the fixing assembly includes an outer mounting block 21. The outer wall of the outer mounting block 21 is fixedly connected to the inner wall of the connecting rod 3 16, which provides a basic connection part for the installation of the screw 6. A connecting block 19 is fixedly connected to the groove of the connecting rod 3 16, and a clamping block 20 is fixedly connected to the side of the connecting rod 3 16 away from the connecting rod 3. By fixing the clamping block 20 to one side of the connecting rod 3 16, it is convenient for the subsequent clamping block 20 to fix the inner mounting block 18. The clamping block 2 The outer wall 20 is slidably connected to the inner mounting block 18, and the outer wall of the inner mounting block 18 is fixedly connected to the screw 6. The inner mounting block 18 and the outer mounting block 21 work together to realize the rapid installation and removal of the screw 6. When the screw 6 needs to be replaced, the outer shell 5 needs to be disassembled first. At this time, the operator only needs to pull the screw 6. One end of the screw 6 is fixedly connected to the clamping block 17, and the outer wall of the clamping block 17 is slidably connected to the inner wall of the outer mounting block 21. The cooperation between the clamping block 17 and the outer mounting block 21 further ensures the stability of the connection between the screw 6 and the connecting rod 3 16, and also facilitates the installation and removal operations of the screw 6.

[0025] Reference Figures 1-3The upper surface of the shell 5 is fixedly connected to a hopper 1, and the hopper 1 is used to store the inert powder to be transported. The input end thereof is fixedly connected to a bracket 2, and the bracket 2 provides an installation position for a motor 3. The upper surface of the bracket 2 is fixedly connected to a motor 3, and the motor 3 serves as the power source of the stirring device in the hopper 1. The output end of the motor 3 is fixedly connected to a connecting rod 8, and the connecting rod 8 transmits the power of the motor 3 to the agitator 12 and the brush 9. The outer wall of the connecting rod 8 is fixedly connected to a connecting rod 2 11, and the connecting rod 2 11 serves to connect the fixed ring 10 and the connecting rod 8, so that the fixed ring 10 can rotate with the connecting rod 8. The connecting rod 2 11 is fixedly connected to the fixing ring 10 at one end away from the connecting rod 8, and the fixing ring 10 provides an installation base for the brush 9 to ensure that the brush 9 will not deviate during the rotation process. The outer wall of the fixing ring 10 is fixedly connected to the brush 9, and the outer wall of the brush 9 is slidingly connected Connected to the inner wall of the hopper 1, driven by the connecting rod 18, the brush 9 slides along the inner wall of the hopper 1. On the one hand, it sweeps off the dust attached to the inner wall of the hopper 1 during the mixing process, ensuring the effective volume of the hopper 1 and the normal falling of the material; on the other hand, it cleans the inner wall of the hopper 1, reduces dust residue, and reduces the risk of explosion. The outer wall of the connecting rod 8 is fixedly connected to the stirrer 12, and the outer wall of the stirrer 12 is rotatably connected to the inside of the hopper 1. The stirrer 12 rotates at high speed under the drive of the motor 3, which can effectively break up the agglomerated dust, so that the material maintains good fluidity, avoids accumulation and blockage of the material in the hopper 1, ensures smooth material discharge, and improves the conveying efficiency. The outer wall of the hopper 1 is fixedly connected to the bracket 2 13, and the lower surface of the bracket 2 13 is fixedly connected to the upper surface of the shell 5. The bracket 2 13 strengthens the connection between the hopper 1 and the shell 5, so that the hopper 1 is more firmly installed on the shell 5.

[0026] Working principle: When operating the conveying device, the screw 6 needs to be replaced first. First, screw the screw 22 to disassemble the shell 5. After the shell 5 is disassembled, the operator only needs to pull the screw 6 outward with force to make the block 17 at one end of the screw 6 disengage from the inner wall of the outer mounting block 21, and at the same time, the block 20 slides out from the inner mounting block 18, and the connection between the block 17 and the outer mounting block 21 and the block 20 and the inner mounting block 18 is released. The screw 6 can be easily taken out from the connecting rod 3 16 for replacement. When installing the new screw 6, it is only necessary to align the block 17 with the inner wall of the outer mounting block 21 and insert it, and at the same time make the block 20 slide into the inner mounting block. By installing the block 18, the screw 6 can be quickly installed. This unique fixed component design greatly facilitates the replacement operation of the screw 6. Compared with the traditional screw 6 installation structure, it significantly shortens the replacement time of the screw 6, reduces the difficulty of maintenance, reduces the equipment downtime, effectively improves the production efficiency, reduces the equipment maintenance cost, and ensures the stable operation of the production system. When the screw 6 is installed, the material can be transported, the motor 3 starts to work, and its output end drives the connecting rod 8 to rotate. The agitator 12 fixedly connected to the connecting rod 8 rotates at high speed inside the hopper 1 as the connecting rod 8 rotates. The blades stir the inert powder in the hopper 1. The strong stirring force can effectively break up the dust that may be agglomerated, destroy the adhesion between the dust particles, and restore the material to good fluidity, thereby avoiding the accumulation of materials in the hopper 1 to form a blockage, ensuring that the material can smoothly enter the shell 5 from the hopper 1, providing a guarantee for the subsequent conveying process, and improving the material conveying efficiency of the entire conveying mechanism. In addition, the rotation of the connecting rod 8 can drive the brush 9 to scrape the inner wall of the hopper 1, and the dust on the inner wall can be cleaned by the sliding of the brush 9. During transportation, the dust stuck to the inner wall of the hopper 1 can be removed. Scrape it down to prevent dust accumulation. After the transportation work is completed, the hopper 1 can be cleaned by sliding the brush 9, which is convenient for cleaning. The broken material is transported to the inside of the shell 5 through the output end of the hopper 1. At this time, the screw 6 is driven to rotate by the motor 2 7, and its output end drives the connecting rod 3 16 to rotate. Since the gear 15 is fixedly connected to the connecting rod 3 16, the gear 15 rotates together, and the gear 15 and the screw 6 cooperate with each other. Under the rotation action of the gear 15, the two screws 6 are synchronously rotated in the shell 5, and the dust entering the inside of the shell 5 is squeezed, and a second breakup is performed to facilitate transportation.
