technical field

The utility model relates to a ribbon mixer.

Background technique

The mixer in the prior art includes a frame and a mixing barrel fixedly arranged on the frame. A stirring shaft is arranged to rotate in the mixing barrel, and a number of stirring blades are arranged on the stirring shaft. Although the above-mentioned structure adopts stirring blades to carry out Mixing, but the mixing effect is poor, and a larger power drive is required to improve the mixing effect.

Contents of the invention

The purpose of the utility model is to overcome the defects in the prior art and provide a ribbon mixer with good mixing effect.

In order to achieve the above object, the technical solution of the utility model is to provide a ribbon mixer, comprising a supporting frame, a mixing barrel fixedly arranged on the supporting frame, the upper part of the mixing barrel is provided with an advanced Material port, the lower part of the mixing barrel is provided with a discharge port, the discharge port is provided with a discharge device, the upper part of the mixing barrel is rectangular, and the lower part of the mixing barrel is semi-cylindrical, A stirring shaft is arranged to rotate in the mixing barrel, and the stirring shaft is driven to rotate by a power device arranged on the support frame, and a first stirring ribbon and a second stirring ribbon are arranged on the stirring shaft along its length direction. Stirring ribbon, the helical direction of the first stirring ribbon is opposite to the helical direction of the second stirring ribbon, the side wall of the mixing barrel is a hollow structure, and the cavity of the side wall of the mixing barrel Connect to heating or cooling device.

A further improvement is that: the unloading device includes a discharge door slidably arranged at the discharge port, and a discharge cylinder that drives the slide of the discharge door.

A further improvement is: the power device includes a motor arranged on the supporting frame, a speed reducer connected to the motor through a transmission mechanism, the output shaft of the speed reducer is connected to the stirring shaft through a coupling connected.

A further improvement is: the transmission mechanism is a belt pulley transmission mechanism.

A further improvement is that: both ends of the stirring shaft are connected with the supporting frame through rotating bearings.

The advantages and beneficial effects of the utility model are: by adopting the first stirring ribbon with the opposite spiral direction and the second stirring ribbon for mixing and stirring, the material forms more eddy currents during the stirring process, thereby improving the stirring and mixing effect, and Only a small power is needed to achieve strong mixing. In addition, the mixing barrel is set in a U shape to facilitate unloading, so that the material will not form residues in the mixing barrel.

detailed description

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is further described. The following examples are only used to illustrate the technical solution of the utility model more clearly, but not to limit the protection scope of the utility model.

As shown in Figure 1, a kind of ribbon mixer comprises a support frame 1, a mixing barrel 2 fixedly arranged on the support frame 1, the top of the mixing barrel 2 is provided with a feed inlet 3, The bottom of the mixing barrel 2 is provided with a discharge port 4, the discharge port 4 is provided with a discharge device, the upper part of the mixing barrel 2 is rectangular, and the bottom of the mixing barrel 2 is a semi-cylindrical shape, the mixing barrel 2 is provided with a stirring shaft 5 for rotation, and the stirring shaft 5 is driven to rotate by the power device arranged on the support frame 1, and the stirring shaft 5 is provided with a second shaft along its length direction. A stirring ribbon 6 and a second stirring ribbon 7, the helical direction of the first stirring ribbon 6 is opposite to that of the second stirring ribbon 7, and the side wall of the mixing barrel 2 is a hollow structure The cavity of the side wall of the mixing barrel 2 is connected with a heating device or a cooling device, the heating device can be heated by steam or heat transfer oil, and the cooling device can be cooled by circulating water.

Working principle: By using the first stirring ribbon 6 and the second stirring ribbon 7 with opposite helical directions for mixing and stirring, the material will form more eddy currents during the stirring process, thereby improving the mixing effect and requiring only a small The power is to achieve strong mixing. In addition, the mixing barrel 2 is set in a U shape, which is convenient for unloading, so that the material will not form residues in the mixing barrel 2.

In order to facilitate automatic unloading, the unloading device includes a unloading door 11 slidably arranged at the discharge port 4 , and an unloading cylinder 12 that drives the unloading door 11 to slide.

The preferred implementation mode in this embodiment is that the power device includes a motor 8 arranged on the support frame 1, a reducer 9 connected to the motor 8 through a transmission mechanism, and the output of the reducer 9 The shaft is connected with the stirring shaft 5 through a coupling 10 .

A preferred implementation manner in this embodiment is that the transmission mechanism is a belt pulley transmission mechanism.

A preferred implementation manner in this embodiment is that both ends of the stirring shaft 5 are connected with the support frame 1 through rotating bearings.

The above is only the preferred embodiment of the utility model, and it should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the utility model, some improvements and modifications can also be made. And retouching should also be regarded as the protection scope of the present utility model.
