Description

Mixer

The utility model relates to a kind of material evenly mixing device.

Existing solid material mixing does not have special equipment, mainly is to use existing mixing plant.And these mixing plants are divided into continuous operation and discontinuous operation dual mode.With the double-shaft spiral mixer is the continuous operation mixer of representative, is to utilize the helical axis of two relative motions laterally to place side by side, and material is fed forward while stirring.This mixer can be fit to the streamline of continuous operation, but because the pan feeding direction has bigger inclination angle (vertical) with the helical axis throughput direction, helical axis not only will overcome owing to the gravitional force that pan feeding caused, and changes the direction of motion of material, also will drive static material and stir.Therefore this mixer power consumption is very big, and the mixing effect is also not ideal enough.With the concrete mixer is the batch agitator of representative, be after the rotation of utilize stirring body is carried out the stirring of certain hour to material, shuts down to pack into or draw off material.This mixer is effective to the various materials mixing, but owing to need to shut down the loading and unloading material, influences production efficiency, nor be suitable for the needs of the streamline of continuous operation.

The pluses and minuses of comprehensive above-mentioned two kind equipments, the purpose of this utility model provide that a kind of power consumption is low, and batch mixing is even, is suitable for the special-purpose mixing machine of continuous operation streamline.

For achieving the above object, the utility model is taked following design: a kind of mixing machine, it comprises frame, casing, motor, decelerator and transmission device, described casing is installed on the described frame, described decelerator of described driven by motor and transmission device is characterized in that: it also comprise one have on it at least four even number root handle rod roll cage.Described rolling is provided with one group of deflector that tilts between the per two horizontal rods of cage, the incline direction of the described deflector of two-stage neighboring is opposite, and the described cage that rolls is installed on the described casing by bearing.The top of described casing has feeding mouth, and the bottom of described casing has discharging opening.

Described deflector be shaped as the conical arc surface of part, this taper shape arc surface end face is connected with the described horizontal rod that rolls on the cage.This curved surface material contact back impelling direction is even.

Being shaped as of described deflector is trapezoidal, and its trapezoidal bottom surface is connected with the described horizontal rod that rolls cage.This shape manufacture craft is simple.

Described deflector gap can be divided into even layout and along the water conservancy diversion direction from close to two kinds of thin inhomogeneous layouts.

The utility model is owing to take above design, the kinetic energy and the gravitional force that are produced when reasonably using material to enter mixing machine, direction of motion when mixing just changes the material whereabouts, and do not need to drive static material, therefore only need the low-down power of input just can drive and roll the cage rotation, thereby greatly reduced energy consumption.Simultaneously because the effect of deflector, material is subjected to the transverse cuts of horizontal rod and deflector once even repeatedly rightabout impelling from the feeding mouth to the discharging opening, and the mixing effect is good especially.Feed inlet and outlet is provided with the conveyer belt transmission that is very beneficial for continuous operation in the top and the bottom of casing in addition.It can be widely used in the batching mixing operation of multiple solid materials such as coal blending mixing.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

As shown in Figure 1 and Figure 2, motor 2 is installed at the top of frame 1, and the output shaft of motor 2 connects decelerator 3, connects a minor sprocket 4 on the output shaft of decelerator 3.Casing 5 separated into two parts, lower casing 5 ' are installed on the casing 1, and its bottom has discharging opening 6, and the angle of inclination of discharging opening 6 changes with the incline direction of conveyer belt.Upper casing 5 " be connected with lower casing 5 ' by bolt, its top has feeding mouth 7.Upper and lower enclosure 5 ", 5 ' junction has dead eye, and rolls cage 10 by what two ends of bearing 8 supportings had end plates and an axis 9.Roll on the axis 9 of cage 10 1 ends and fix a hinge wheel 11, be connected a chain 12 between the minor sprocket 4 on hinge wheel 11 and the decelerator 3.As shown in Figure 3, outside the circumference that rolls cage 10,, between two horizontal rods 13, arrange one group of five deflector 14 equably through being welded with the horizontal rod 13 of the six roots of sensation.The shape of deflector 14 is the conical arc surfaces (as Fig. 4, shown in Figure 5) of part, and the end face two ends of conical arc surface are welded on respectively on two horizontal rods 13 (as shown in Figure 3), deflector 14 with roll cage 10 cross sections and have certain angle of inclination.During installation, the angle of inclination of two groups of adjacent deflectors 14 and curved surface bending direction are contrary.

As shown in Figure 6, in the foregoing description, the shape of deflector 14 also can be trapezoidal.Two ends, trapezoidal bottom surface are connected with adjacent two horizontal rods 13 respectively.Deflector 14 between two horizontal rods, along the water conservancy diversion direction of deflector 14 at interval by close to thin non-homogeneous layout.The incline direction of two groups of adjacent deflectors 14 is just in time opposite with interval density.This mainly is to consider, along the water conservancy diversion direction the closer to the material that rolls the cage end plate after diversed plate 14 impellings, by end plate reflect many more, in order further to reduce power attenuation, deflector 14 gaps the closer to end plate are sparse more, even can not establish deflector at last, the material fusion mixing that the material of coming by the opposite side impelling and this side directly fall.

Some structures all can be exchanged in the various embodiments described above, also can evenly arrange such as trapezoidal deflector, and the conical curved guide plate of part also can inhomogeneously be arranged.Evenly its tie point of deflector of arranging also can be on same cross section on same cross section.The shape of deflector can also be a multiple shape such as parabola shaped.Deflector and horizontal rod, horizontal rod with roll cage be connected except that the welding also can take alternate manner.Transmission system also can use belt to carry, or other mode of movement, and this mainly is to determine according to the difference of desired mixt material.
