Description

Technical Field

[0001] This utility model relates to the field of stirring shaft technology, and in particular to a power-driven oxygen supply stirring shaft. Background Technology

[0002] Currently, most mechanical stirring shafts are cross-shaped, S-shaped, or spiral-shaped, resulting in high noise levels, easy wear on other mechanical parts, energy waste, uneven mixing, and significant residue that is difficult to clean. These manufacturing processes are time-consuming, labor-intensive, and environmentally unfriendly. To address this, a green, environmentally friendly, user-friendly, quiet, non-damaging, energy-saving, and uniformly mixing stirring shaft that is easy to clean and leaves no residue is needed. Application number 201420559603.0 discloses a power-driven oxygen-supplying stirring shaft structure. This stirring shaft is a Y-shaped thick-walled tubular shaft with pre-reserved ventilation holes at the mixing wall connection and connecting shafts at the top and bottom, forming a power-driven oxygen-supplying stirring shaft.

[0003] The existing stirring shaft is inconvenient to use, cannot perform oxygen-supply stirring, and the stirring structure cannot be replaced or repaired after damage, thus failing to meet the usage requirements. Summary of the Invention

[0004] The purpose of this invention is to solve the shortcomings of existing stirring shafts, such as inconvenience in use, inability to perform oxygen-supply stirring, inability to replace the stirring structure, inability to repair after damage, and failure to meet usage requirements. Therefore, a power-driven oxygen-supply stirring shaft is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power-driven oxygen-supplying stirring shaft includes a cylinder with a rotating rod rotatably mounted on it. A fan is installed inside the cylinder on the rotating rod. An air hole is opened at the top of the cylinder. Two U-shaped seats are fixedly mounted at the top of the cylinder, and a fixing mechanism is set between the two U-shaped seats. A motor is mounted on the fixing mechanism. A polygonal rod is fixedly mounted on the output shaft of the motor. A polygonal groove is opened at the top of the rotating rod, and the polygonal rod is adapted to the polygonal groove. Multiple stirring structures are provided on the outer side of the rotating rod.

[0007] Preferably, a dustproof net is provided on the outside of the air hole, and an oxygen supply pipe is provided at the bottom of the cylinder.

[0008] Preferably, the fixing mechanism includes two arc-shaped clamps, each with a rubber pad on its inner side, and two bidirectional screws rotatably mounted on the inner sides of the two U-shaped seats. The two ends of the arc-shaped clamps are threadedly connected to the two bidirectional screws, with the two ends of the bidirectional screws having opposite thread directions. The outer ends of the bidirectional screws extend to the outer side of the U-shaped seats and are fitted with internal hexagon heads.

[0009] Preferably, each of the two U-shaped seats is provided with a guide rod, and the two ends of the arc-shaped clamp are slidably mounted on the outside of the two guide rods.

[0010] Preferably, the stirring structure includes a stirring plate, on which an installation block is fixedly mounted. Multiple installation grooves are provided on the outer side of the rotating rod. The installation block is movably connected to the installation grooves. Multiple bolts are threadedly connected to the outer side of the rotating rod. The ends of the bolts extend into the installation grooves and press against the installation block.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] This solution involves installing a cylinder on the container that needs to be processed and stirred. The motor starts and drives the rotating rod to rotate, which in turn drives multiple stirring plates to stir. The rotating rod also drives the fan to rotate, and outside air enters the container through an oxygen supply pipe.

[0013] When the motor needs to be replaced, use the hex wrench to rotate the corresponding double-ended screw. The double-ended screw will cause the two arc-shaped clamps to move away from each other, which can release the two arc-shaped clamps from fixing the motor. The motor can then be disassembled. During installation, insert the polygonal rod into the polygonal groove and re-fix the motor. The mixing plate can also be disassembled. Loosen the bolts to release the fixing of the mounting block and the mixing plate can be disassembled and replaced. This can be done after the mixing structure is damaged.

[0014] This invention has a simple structure and can simultaneously introduce oxygen while stirring, achieving the goal of simultaneous stirring and oxygen supply. It also allows for easy replacement of the stirring structure. Attached Figure Description

[0023] In this embodiment, the fixing mechanism includes two arc-shaped clamps 4, each with a rubber pad 9 on its inner side. Two bidirectional screws 7 are rotatably mounted on the inner sides of two U-shaped seats 3. The two ends of the arc-shaped clamps 4 are threadedly connected to the two bidirectional screws 7, with opposite thread directions at both ends. The outer ends of the bidirectional screws 7 extend to the outer side of the U-shaped seat 3 and are fitted with hexagonal heads 6. Using a hex wrench, the hexagonal heads 6 rotate, causing the corresponding bidirectional screws 7 to rotate. The bidirectional screws 7 cause the two arc-shaped clamps 4 to move away from each other, releasing the two arc-shaped clamps 4 from the motor 5. The motor 5 can then be disassembled. Reversing the rotation of the hexagonal heads 6 fixes the motor 5.

[0024] In this embodiment, guide rods 8 are provided inside both U-shaped seats 3, and the two ends of the arc-shaped clamps 4 are slidably installed on the outside of the two guide rods 8; the guide rods 8 guide the two arc-shaped clamps 4.

[0025] In this embodiment, the stirring structure includes a stirring plate 12, on which an mounting block 14 is fixedly installed. A plurality of mounting grooves 13 are provided on the outer side of the rotating rod 11. The mounting block 14 is movably connected to the mounting grooves 13. A plurality of bolts 15 are threadedly connected to the outer side of the rotating rod 11. The ends of the bolts 15 extend into the mounting grooves 13 and press against the mounting block 14. By loosening the bolts 15 to release the fixing of the mounting block 14, the stirring plate 12 can be disassembled and replaced. It can be replaced after the stirring structure is damaged.

[0026] Working principle: During use, the cylinder 1 is installed on the container to be processed and stirred. The cylinder 1 is embedded in the container, and the oxygen supply pipe 2 is located inside the container. The power supply and control switch of the motor 5 are turned on, and the motor 5 starts to drive the rotating rod 11 to rotate. The rotating rod 11 drives multiple stirring plates 12 to stir. The rotating rod 11 drives the fan 10 to rotate, and the outside air enters the container through the oxygen supply pipe 2. When the motor 5 needs to be replaced, the hex wrench with the internal hex head 6 is used to drive the corresponding double-ended screw 7 to rotate. The double-ended screw 7 drives the two arc-shaped clamps 4 to move away from each other, which can release the two arc-shaped clamps 4 from fixing the motor 5, and the motor 5 can be disassembled. During installation, the polygonal rod 17 is inserted into the polygonal groove 16 to re-fix the motor 5. The stirring plates 12 can also be disassembled. Loosen the bolts 15 to release the fixing of the mounting block 14, and the stirring plates 12 can be disassembled and replaced. Replacement can be performed after the stirring structure is damaged.

[0027] Example 2

[0028] The difference between Embodiment 2 and Embodiment 1 is that the air hole 18 is replaced with a pipe. The pipe is used to connect the oxygen tank and can directly introduce oxygen into the cylinder 1 to meet the oxygen supply requirements. All structures in this application can be selected in terms of material and length according to actual use. The attached drawings are schematic structural diagrams, and the actual dimensions can be adjusted appropriately.
