Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealed barrel technology, and in particular to a retractable stirring rod for sealed barrels. Background Technology
[0002] A sealed container is a closed container used for storing or handling substances. It typically features airtightness, pressure resistance, and corrosion resistance. It is commonly used in the chemical industry, food and pharmaceutical industries, and laboratories. Some sealed containers have built-in or external stirring rods for mixing materials.
[0003] In chemical production, pharmaceutical processing, and hazardous waste treatment, sealed containers are often used to store viscous, corrosive, or reactive chemicals. To prevent materials from clumping together or stratifying due to standing, stirring rods are usually installed inside the sealed container to periodically mix the materials. However, after completing the mixing task, existing stirring rods need to be removed manually or by external equipment. If the stirring rods are immersed in the chemical medium for a long time, their surface may be damaged due to corrosion, oxidation, or chemical reactions, shortening their service life. At the same time, residual chemicals may adhere to the stirring rods, causing cross-contamination or affecting subsequent operations. In addition, frequent disassembly of the stirring rods not only increases labor costs and operational risks but may also compromise the sealing of the sealed container, leading to leakage of volatile substances or intrusion of external impurities.
[0004] Therefore, there is an urgent need to provide a retractable stirring rod in a sealed container to solve the above problems. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a retractable stirring rod in a sealed container.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a retractable stirring rod in a sealed container, including an air compressor, a feeding roller and a sealed container, wherein a rope is fixedly connected inside the feeding roller, the air compressor is used to drive the feeding roller to rotate, thereby realizing the feeding and rewinding of the rope, and the sealed container is used to store substances, and also includes;
[0007] A fixing block is fixedly installed inside the sealed barrel;
[0008] A stirring mechanism is slidably connected inside the sealed container. The stirring mechanism is used to stir the substances inside the sealed container. The fixing block restricts the stirring mechanism to enable its extension and retraction.
[0009] The present invention is further configured such that: a cylinder is provided inside the air compressor, a piston is slidably connected inside the cylinder, a moving rod is fixedly installed on the surface of the piston, a rack is fixedly installed on the surface of the moving rod, a spring is fixedly connected between the piston and the inner wall of the cylinder, and a transmission mechanism is fixedly installed inside the air compressor, the transmission mechanism including a crankshaft, a connecting rod and an engine.
[0010] Through the above technical solution, the transmission mechanism enables the piston inside the cylinder to move, which in turn pushes the moving rod to move. Through the meshing of the rack and gear, the roller shaft of the wire feeding roller rotates, thereby realizing the wire feeding.
[0011] The present invention is further configured such that: a roller shaft is rotatably connected inside the wire feeding roller, and a gear is fixedly installed at the end of the roller shaft, the gear meshing with a rack.
[0012] Through the above technical solution, the rotation of the gear drives the rotation of the roller shaft, enabling the rope to be unloaded, and further enabling the stirring mechanism to rise and fall inside the sealed tank.
[0013] The present invention is further configured such that: an auxiliary roller is fixedly installed on the surface of the sealed barrel, the rope is slidably connected to the surface of the auxiliary roller, a sealing cover is detachably installed on the surface of the sealed barrel, and a breather valve and a pressure relief valve are fixedly installed on the surface of the sealed barrel.
[0014] Through the above technical solutions, the auxiliary roller makes the rope more stable when sliding and always keeps it in the center line position of the sealed barrel during the sliding process. The sealing cover protects the sealed barrel. The breathing valve balances the pressure inside the barrel and prevents overpressure or collapse due to temperature changes. The pressure relief valve automatically opens under abnormal pressure to ensure safety.
[0015] The present invention is further configured such that: a through hole is provided inside the fixing block, and a guide rod is fixedly connected between the surface of the fixing block and the inner wall of the sealed barrel.
[0016] Through the above technical solution, the through hole restricts the stirring rod. When the stirring mechanism rises inside the sealed tank, the edge of the through hole contacts the stirring rod and squeezes it, causing the stirring rod to rotate and close, thus completing the contraction of the stirring rod.
[0017] The present invention is further configured such that: the stirring mechanism includes a mounting frame, the other end of the rope is fixedly connected to the surface of the mounting frame, a motor is fixedly installed inside the mounting frame, a transmission rod is drivenly connected to the output end of the motor, a plurality of mounting blocks are fixedly installed on the surface of the transmission rod, and a plurality of stirring rods are rotatably connected inside the mounting blocks.
[0018] With the above technical solution, when the wire feeding roller feeds the wire, the rope length increases, the stirring mechanism moves to the bottom of the sealed barrel and starts the motor, the transmission rod rotates, the mounting block follows the rotation and makes the stirring rod stir. When the wire feeding roller retracts the wire, the rope length decreases, the stirring mechanism rises into the through hole, and the stirring rod completes the retraction.
[0019] The present invention is further configured such that: a plurality of rotating grooves are provided on the lower surface of the mounting block; the stirring rod is rotatably connected inside the rotating groove; a rotating shaft is fixedly connected inside the rotating groove; the stirring rod is rotatably connected to the surface of the rotating shaft; a torsion spring is fixedly connected between the surface of the stirring rod and the inner wall of the rotating groove; and symmetrical extension blocks are fixedly installed on the surface of the mounting frame; the extension blocks are slidably connected to the surface of the guide rod.
[0020] With the above technical solution, when the stirring rod descends from the inside of the through hole, the stirring rod loses its compression. Under the action of the torsion spring, the rotating shaft drives the stirring rod to rotate, and the stirring rod gradually unfolds from the closed state, which facilitates the stirring work. The extension block, together with the guide rod, makes the stirring mechanism more stable when it rises and falls inside the sealed barrel, and at the same time ensures that the stirring rod can always be located in the center position of the sealed barrel for stirring work.
[0021] The beneficial effects of this utility model are as follows:
[0022] This utility model is equipped with an air compressor and a wire feeding roller. The air compressor moves the moving rod, which in turn rotates the wire feeding roller, realizing the wire feeding and winding work. This allows the stirring mechanism to extend and retract inside the sealed tank, protecting the stirring rod, thereby extending the service life of the stirring rod, reducing labor costs, and lowering the risk of manual operation.

The transmission mechanism includes a crankshaft, a connecting rod and an engine.
[0032] In this embodiment: the transmission mechanism enables the piston 12 inside the cylinder 11 to move, further pushing the moving rod 13 to move. Through the meshing of the rack 14 and the gear 22, the roller shaft 21 of the wire feeding roller 2 is rotated, thereby realizing the wire feeding of the rope 23.
[0033] like Figure 2 As shown, a roller shaft 21 is rotatably connected inside the wire feeding roller 2, and a gear 22 is fixedly installed at the end of the roller shaft 21. The gear 22 meshes with the rack 14.

[0035] like Figure 2 As shown, an auxiliary roller 31 is fixedly installed on the surface of the sealed barrel 3, and a rope 23 is slidably connected to the surface of the auxiliary roller 31. A sealing cover is detachably installed on the surface of the sealed barrel 3, and a breather valve and a pressure relief valve are fixedly installed on the surface of the sealed barrel 3.

[0037] A fixing block 4 is fixedly installed inside the sealed barrel 3.
[0038] like Figure 2 As shown, a through hole 41 is provided inside the fixing block 4, and a guide rod 42 is fixedly connected between the surface of the fixing block 4 and the inner wall of the sealed barrel 3.
[0039] In this embodiment: the through hole 41 restricts the stirring rod 55. When the stirring mechanism 5 rises inside the sealed barrel 3, the edge of the through hole 41 contacts the stirring rod 55 and squeezes the stirring rod 55. The stirring rod 55 rotates and closes, completing the contraction of the stirring rod 55.
[0040] A stirring mechanism 5 is slidably connected inside the sealed container 3. The stirring mechanism 5 is used to stir the substance inside the sealed container 3. The fixing block 4 restricts the stirring mechanism 5 to achieve the extension and retraction of the stirring mechanism 5.

After stirring is completed, the air compressor 1 releases air, the moving rod 13 moves backward, and the feeding roller 2 rotates to retract the rope, shortening the length of the rope 23. The stirring mechanism 5 rises into the through hole 41, which restricts the stirring rod 55. When the stirring mechanism 5 rises inside the sealed barrel 3, the edge of the through hole 41 contacts the stirring rod 55 and squeezes it. The stirring rod 55 rotates and closes, completing the contraction of the stirring rod 55.
