A driven gear that meshes with gears.

The beneficial effects of the utility model

In the double-paddle trough-shaped mixer protected by the utility model, when two or more powder materials or materials with poor fluidity such as slag need to be mixed, the items are put into the top of the U-shaped stirring tank after Cover the upper cover, and then start the stirring shaft driving device to drive the two parallel stirring shafts to rotate in the opposite direction. The inclined connecting section between the installation section and the middle vertical installation section, and the vertical installation sections at both ends of the paddle stirring blade are located on different sides of the stirring shaft, and the ends of the vertical installation sections at both ends and the middle vertical installation section The movable shaft sleeves are respectively installed, and the stirring shaft passes through the movable shaft sleeves at the vertical installation section at both ends and the middle vertical installation section respectively. It ensures the radial, axial and annular movement of the material to form a compound cycle, which can be fully and uniformly mixed in a very short period of time.

After the stirring, the stirring tank motor drives the half shaft of the stirring tank to rotate, so that the U-shaped stirring tank is turned 180°, so that the top opening is facing down, and the material can be quickly poured from the U-shaped stirring tank to the lower container. , Since the stirring tank is U-shaped, the material will not adhere to the inner arm of the stirring tank, and the material will be poured out more cleanly and thoroughly.

Detailed ways

A double-paddle trough mixer, which includes a frame 4, a U-shaped stirring tank 2 with an upper opening and a stirring mechanism, and two opposite and coaxial stirring tank half shafts 5 are installed on the frame, one of which is The half shaft of the stirring tank is driven and rotated by the stirring tank motor 1, and the stirring tank is installed between the two half shafts. After the stirring, the stirring tank motor drives the half shaft of the stirring tank to rotate, which can make the U-shaped stirring tank turn 180°. Keep the top opening facing down to facilitate pouring out. An upper cover 6 is installed on the top of the stirring tank to prevent the material from being ejected from the top opening during the stirring process.

The stirring mechanism includes two parallel stirring shafts installed in the stirring tank, a paddle stirring blade installed on the stirring shaft and a stirring shaft driving device, and the paddle stirring blade includes vertical installation sections 9 at both ends, The middle vertical installation section 10 and the inclined connection section 12 connected between the vertical installation sections at both ends and the middle vertical installation section, and the vertical installation sections at both ends of the paddle stirring blade are located on different sides of the stirring shaft, and both ends The end of the vertical installation section and the middle vertical installation section are respectively installed with movable shaft sleeves 11, and the stirring shaft passes through the movable shaft sleeves at both ends of the vertical installation section and the middle vertical installation section, respectively. The driving device drives the two parallel stirring shafts to rotate in the opposite direction, which can ensure the radial, axial and annular movement of the material to form a compound circulation, so that the material can be mixed quickly and evenly.

Further, the stirring shaft driving device is the stirring motor 3 that is fixedly installed on the frame, and the motor shaft of the stirring motor is connected with the active stirring shaft 15 through the coupling 7, and the motor shaft is sleeved with the driving gear 8, and the passive stirring shaft 13 The upper sleeve is equipped with a passive gear 14 meshing with the driving gear, which makes the operation of the stirring device more stable and reliable, and can drive the two stirring shafts to rotate in the opposite direction through one motor, which reduces the purchase cost and operating cost, and ensures that the two stirring shafts are rotated in the opposite direction. The synchronization of the shaft achieves better coordination, and the stirring is even and there is no dead angle. The motor shaft of the stirring motor is connected with the active stirring shaft through the coupling, which can prevent the oil in the motor box from entering the polluted material in the tank.

When two or more powdery materials or materials with poor fluidity such as slag need to be mixed, put the items from the top of the U-shaped stirring tank into the back cover and cover it, and then start the stirring shaft driving device to drive the two The parallel-arranged stirring shafts rotate in the opposite direction, because the paddle-type stirring blade includes vertical installation sections at both ends, a vertical installation section in the middle, and an inclined connection section connected between the vertical installation sections at both ends and the vertical installation section in the middle. And the vertical installation sections at both ends of the paddle stirring blade are located on different sides of the stirring shaft, the ends of the vertical installation sections at both ends and the middle vertical installation section are respectively installed with movable bushings, and the stirring shaft is vertically installed from both ends. The movable shaft sleeves at the straight installation section and the middle vertical installation section pass through. When the two stirring shafts are rotated in the opposite direction, they can achieve good cooperation to ensure the radial, axial and annular movement of the material. The compound cycle can be fully and uniformly mixed in a very short time.

After the stirring, the stirring tank motor drives the half shaft of the stirring tank to rotate, so that the U-shaped stirring tank is turned 180°, so that the top opening is facing down, and the material can be quickly poured from the U-shaped stirring tank to the lower container. , Since the stirring tank is U-shaped, the material will not adhere to the inner arm of the stirring tank, and the material will be poured out more cleanly and thoroughly.

To sum up, the double-paddle trough mixer protected by the present application can stir materials evenly and thoroughly, with good stirring effect and high stirring efficiency, and at the same time, it is convenient for material to be poured out.
