A gear is provided on the lead screw, and a toothed ring that meshes with the gear is provided on the vertical rod.

[0010] The pneumatic mixing mechanism includes a box body located on the top of the tank. Each side wall of the box body has an air inlet pipe at both the top and bottom, and the other side wall has an air outlet pipe at both the top and bottom. A piston plate is also installed inside the box body. A top rod connected to the piston plate is mounted on the top of the mounting plate. An annular seat, connected to the top of the tank body via a mounting rod, is fitted over a vertical rod between the annular plate and the toothed ring. The vertical rod inside the annular seat has a circular cross-section. An air inlet channel is also arranged around the side wall of the annular seat. The air outlet pipe is connected to the air inlet channel via a flexible hose. Corresponding connecting holes are provided on the inner side wall of the annular seat and the side wall of the vertical rod, connecting the air inlet channel and the connecting channel.

[0011] Preferably, the annular plate is provided with a screw hole for the lead screw to pass through, wherein the lead screw is screwed into the screw hole.

[0021] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0022] A sedimentation-preventing storage tank includes a tank body 1, wherein a feed pipe is provided at the top of the tank body 1 and a discharge pipe is provided at the bottom of the tank body 1.

[0023] The tank 1 is equipped with an agitation mechanism 2, which is provided with a lifting mechanism 3 and a pneumatic mixing mechanism 4.

[0024] The stirring mechanism 2 includes a polygonal vertical rod 22 driven by a motor 21. The bottom end of the vertical rod 22 is provided with a connecting channel 23. The bottom end of the vertical rod 22 is covered with a sleeve 24 with a bottom seal. Various stirring tubes 25 are radially arranged on the inner and outer walls of the sleeve 24. Multiple sets of one-way holes 26 are evenly arranged on the side walls of the stirring tubes 25.

[0025] The lifting mechanism 3 includes a mounting plate 31 set at the top of the sleeve 24. An annular plate 32 is sleeved on the vertical rod 22 above the sleeve 24, and a T-shaped groove 33 is arranged around the bottom edge of the annular plate 32. A T-shaped sliding rod 34 is set at the top of the mounting plate 31 and located in the groove 33. A lead screw 35 is also set on the mounting plate 31 and connected to the inner top wall of the tank 1 through a bearing. A screw hole for the lead screw 35 to pass through is provided on the annular plate 32, and the lead screw 35 is screwed into the screw hole. A gear 36 is set on the lead screw 35, and a toothed ring 37 that meshes with the gear 36 is set on the vertical rod 22.

[0026] The pneumatic mixing mechanism 4 includes a box 41 set on the top of the tank 1. Each side wall of the box 41 has an air inlet pipe 42 at both the top and bottom, and an air outlet pipe 43 at each of the top and bottom of the other side wall. An electromagnetic valve is installed on the air inlet pipe 42, and a check valve is installed on the air outlet pipe 43. A piston plate 44 is also installed inside the box 41. A top rod 45 connected to the piston plate 44 is installed on the top of the mounting plate 31. An annular seat 46, connected to the top of the tank 1 via the mounting rod 47, is fitted over the vertical rod 22 between the annular plate 32 and the toothed ring 37. The vertical rod 22 inside the annular seat 46 has a circular cross-section. An air inlet channel 48 is also arranged around the side wall of the annular seat 46. The air outlet pipe 43 is connected to the air inlet channel 48 via a flexible hose 49. A connecting hole 410, connecting the air inlet channel 48 and the connecting channel 23, is correspondingly provided on the inner side wall of the annular seat 46 and the side wall of the vertical rod 22.

[0027] The size of the vertical rod 22 is adapted to the size of the internal opening of the sleeve 24. A circular tube 5 is provided at the connection between the stirring tube 25 and the internal opening of the sleeve 24. Any two adjacent sets of circular tubes 5 are connected by a connecting rod 6. A spring 7 connected to the lowermost circular tube 5 is provided at the bottom of the sleeve 24. A pressure rod 8 is provided at the top of the uppermost circular tube 5, which abuts against the bottom end face of the vertical rod 22 outside the connecting channel 23.

[0028] The method of using the present invention: When the tank 1 stores some substances that are easy to sink, the motor 21 drives the sleeve 24 and the stirring tube 25 through the vertical rod 22 to stir the substances in the tank 1 to prevent the substances from sinking. During this process, the sleeve 24 will drive the sliding rod 34 to slide in the sliding groove 33 through the mounting plate 31, thereby suspending and fixing the sleeve 24 and the stirring tube 25 without affecting their rotation.

[0029] When the motor 21 agitates the tank 1 through the vertical rod 22, sleeve 24 and stirring tube 25, the rotating vertical rod 22 drives the gear 36 and lead screw 35 to rotate through the toothed ring 37. The lead screw 35 rotates in the screw hole to drive the annular plate 32 to move upward. The upward-moving annular plate 32 will drive the mounting plate 31, sleeve 24 and stirring tube 25 to move upward through the sliding groove 33 and sliding rod 34. When the above components move upward to a certain extent, the motor 21 reverses, which can drive the above components to move downward and reset. Thus, the stirring tube 25 is driven by the motor 21 to rotate clockwise and counterclockwise to agitate the material. At the same time, the stirring tube 25 and other components can be driven to move up and down to agitate the material in different areas of the tank 1.

[0030] Meanwhile, as the annular plate 32 and sleeve 24 move up and down, the annular plate 32 pushes the piston plate 44 to reciprocate up and down within the housing 41 via the push rod 45. When the piston plate 44 moves upward, it opens the lower intake pipe 42 and closes the upper intake pipe 42. At this time, the piston plate 44 will compress the gas entering the housing 41, forcing it to enter the intake channel 48 through the corresponding exhaust pipe 43 and hose 49, and then through the connecting hole 410 into the connecting channel 23. It should be noted that, since the vertical rod 22 inside the annular seat 46 has a circular cross-section and The size of the ring seat opening is matched so that the ring seat 46 does not affect the rotation of the vertical rod 22. When the gas in the intake channel 48 enters the connecting channel 23 through the connecting hole 410, the gas is not easy to overflow through the gap between the ring seat 46 and the outer wall of the vertical rod 22. When the piston plate 44 moves down, the lower intake pipe 42 is closed and the upper intake pipe 42 is opened. At this time, the piston plate 44 will squeeze the gas entering the box 41 to force it to enter the intake channel 48 through the corresponding exhaust pipe 43 and hose 49, and then enter the connecting channel 23 through the connecting hole 410.

[0031] When the sleeve 24 moves upward, the vertical rod 22 abuts against the upward-moving pressure rod 8 and squeezes the cylinder 5 and connecting rod 6, thereby compressing the spring 7, causing the opening of the cylinder 5 and the stirring tube 25 to be misaligned. At this time, the gas entering the sleeve 24 through the connecting channel 23 will enter the stirring tube 25 and be discharged through the one-way hole 26. The one-way hole 26 can be used to discharge the gas in the stirring tube 25, and at the same time, it can prevent the substance or liquid in the tank 1 from entering the stirring tube 25. The substance in the tank 1 is prevented from sinking to the bottom by the above-mentioned pneumatic stirring method. When the sleeve 24 moves down to the original position, the spring 7 pushes the connecting rod 6 and the cylinder 5 to seal the opening of the stirring tube 25.

[0032] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
