[0002] In the biochemical reaction process of wastewater treatment, a packing flow propulsion device is needed to circulate the packing material containing suspended solids, preventing sedimentation and ensuring biodegradation efficiency. However, existing flow propulsion devices suffer from poor motor sealing reliability. Many use submersible motors that directly contact the wastewater, and the dynamic seal at the shaft end is prone to wear and leakage, leading to short circuits and motor damage. Furthermore, they lack protective structures for the fan blades, which are often clogged by fibers and flocculent material, requiring frequent manual disassembly and cleaning, which not only affects flow efficiency but also increases downtime. Therefore, a packing flow propulsion device with reliable sealing and automatic impurity removal capabilities is needed. Utility Model Content

[0003] The main purpose of this invention is to propose a stainless steel packing jet mixer, which aims to solve the problems of poor motor sealing, easy damage, and easy clogging of the fan blades by impurities in existing packing jet mixers.

[0019] 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.

[0020] To achieve the above-mentioned utility model objectives, such as Figure 1-7 As shown, this utility model provides a stainless steel packing flow actuator. First, a sealing box 1 is prepared, and the drive motor 14 is placed in the installation position inside the sealing box 1, ensuring that the output shaft of the drive motor 14 faces the front end of the sealing box 1. The drive motor 14 is fixed inside the sealing box 1 with bolts. The bolts and the sealing box 1 are made of stainless steel to improve corrosion resistance. The waterproof ring 3 is slipped onto one end of the connecting shaft 15, and the waterproof ring 3 is slowly pushed until it reaches the installation position on the connecting shaft 15. Then, the rear end of the connecting shaft 15 is aligned with the shaft hole at the front end of the sealing box 1 and the output shaft of the drive motor 14. The connecting shaft 15 is connected to the output shaft of the drive motor 14 using a coupling. After installation, the connecting shaft 15 is rotated to make the waterproof ring 3 fit tightly against the inner wall of the shaft hole at the front end of the sealing box 1, ensuring that the waterproof ring 3 forms a reliable seal.

[0021] Embed the sealing strip 12 into the mounting opening of the rear door 11 of the sealing box 1. Hinge the door 11 to the rear of the sealing box 1 using a hinge. Close the door 11 and check whether the sealing strip 12 is in good contact with the sealing surface of the sealing box 1. Fix the handle 13 to the front end of the door 11 with bolts. After tightening the bolts, pull the handle 13 to test whether the door 11 moves smoothly. Connect one end of the conduit 2 to the wiring hole on the top of the sealing box 1, and extend the other end of the conduit 2 to the external power supply equipment.

[0022] Remove the protective frame 6 and insert the bearing 16 into the mounting hole at the center of the rear end of the protective frame 6. The bearing 16 and the mounting hole are fitted with a transition fit. Pass the end of the connecting shaft 15 away from the sealing box 1 through the inner hole of the bearing 16 at the rear end of the protective frame 6 until the front end of the connecting shaft 15 extends into the interior of the protective frame 6. At the part of the connecting shaft 15 inside the protective frame 6, fix the fan blade 5 to the outside of the connecting shaft 15 with screws to prevent the fan blade 5 from loosening during operation. Set connecting rods at both ends of the protective frame 6, and connect the other end of the connecting rods to the front end of the sealing box 1 to prevent the protective frame 6 from rotating with the connecting shaft 15. Fix three fixing blocks 20 by welding at the preset installation position on the outer circumference of the front side of the connecting shaft 15. The three fixing blocks 20 are evenly distributed in the circumferential direction and are located on the rear side of the protective frame 6. After welding, insert the mounting strip 8 into the slot inside the fixing block 20, so that the end of the mounting strip 8 away from the connecting shaft 15 is at a suitable distance from the outer wall of the protective frame 6. Then, install the second screws 18 on both the left and right ends of the fixing block 20 to fix the mounting strip 8 to the fixing block 20. Slide the brush 9 into the mounting groove 19 opened at the end of the mounting strip 8 away from the connecting shaft 15 and push the brush 9 until it reaches the preset position. At this time, the bristles of the brush 9 are in contact with the surface of the through hole 7 at the rear end of the protective frame 6. After the screw hole 4 on the upper side of the rear end of the brush 9 is aligned with the screw on the upper side of the rear end of the mounting strip 8, install the first screw 17 to fix the brush 9 to the mounting strip 8. Finally, fix the handle 10 to the end of the brush 9 away from the connecting shaft 15 with screws. The handle 10 is installed to facilitate subsequent disassembly operations.

[0023] The working process of the stainless steel packing flow mixer provided by this utility model is as follows: After the equipment is started, the drive motor 14 runs inside the sealed box 1. The sealed box 1 completely isolates the motor from the external sewage environment, preventing sewage from entering the motor and causing short circuits or damage. The waterproof ring 3 at the point where the connecting shaft 15 passes through the sealed box 1 acts as a seal, preventing sewage from seeping into the sealed box 1 from the gap between the shaft and the box wall. At the same time, the box door 11 at the rear end of the sealed box 1 cooperates with the sealing strip 12 to further enhance the overall sealing performance of the sealed box 1, ensuring that the drive motor 14 is in a dry operating environment. When the drive motor 14 is running, its output shaft drives the connecting shaft 15 to rotate through the coupling. The connecting shaft 15 then drives the fan blade 5 to rotate at high speed inside the protective frame 6. During the rotation of the fan blade 5, the fan blade 5 rotates at high speed. The water in the sewage treatment tank generates thrust, causing the water to flow and propel the packing material containing suspended solids through the biochemical reaction tank, preventing the packing material from settling to the bottom. While the connecting shaft 15 rotates, driving the fan blade 5 to propel the flow, the connecting shaft 15 also drives the mounting strip 8 to rotate synchronously through the fixing block 20. The mounting strip 8 then drives the brush 9 to rotate around the connecting shaft 15. Since the bristles of the brush 9 are in close contact with the surface of the through hole 7 at the rear end of the protective frame 6, the bristles can continuously sweep away the impurities attached to the surface of the through hole 7 during the rotation of the brush 9. The swept-off impurities are carried into the subsequent sewage treatment process by the water flow, preventing the accumulation of impurities on the surface of the through hole 7 and causing blockage of the through hole 7, ensuring the water flow performance of the protective frame 6 and not affecting the propulsion efficiency of the fan blade 5.

[0024] Preferred method: When the brush 9 needs to be replaced after a period of use, hold the handle 10 on the brush 9 with one hand and loosen the first screw 17 on the upper rear end of the mounting strip 8 counterclockwise with the other hand until the first screw 17 is completely disengaged from the screw hole 4 at the rear end of the brush 9; holding the handle 10, slowly pull the old brush 9 out of the mounting groove 19 on the mounting strip 8, take out the new brush 9, and slowly push it into the mounting groove 19 until the new brush 9 reaches the preset installation position. Adjust the position of the new brush 9 to ensure that the screw hole 4 on the upper rear end of the brush 9 is aligned with the screw on the upper rear end of the mounting strip 8, and tighten the first screw 17 clockwise to complete the replacement of the brush 9.
