The utility model relates to a kind of mixer, belongs to mixing plant technical field.
Mixer is that a kind of blade-carrying axle rotates in cylinder or groove, plurality of raw materials is uniformly mixed, makes it the machine becoming a kind of mixture or suitable denseness.Mixer has been divided into multiple, has forced mixer, single horizontal shaft blender, twin-shaft mixer etc.Mixer is divided into gravity type stirring by agitating mode, forced action type stirs two kinds.Self-dumping mixer is exactly that compound is placed in a mixing drum rotated, and along with the rotation of mixing drum, the blade in drum rises to certain height compound, then freely scatters by deadweight.Carry out so again and again, till mixing thoroughly.The general mixing plasticity of this mixer and semi plastic concrete.Forced mixer is that mixing drum is motionless, and by the blade action of forced stirring that rotating shaft in drum is all put.This mixer mixing quality is good, and production efficiency is high; But power consumption is large, and blade wear is fast, is generally applicable to mixing dry concrete.The agitator tank of prior art utilizes rotating shaft, puddler rotates mixed material, a kind of fodder mixing machine disclosed in a kind of foamed concrete mixer and CN204294143U disclosed in Chinese utility model patent CN204295876U, but, these agitating modes cannot make material especially powder material mix, mixed effect is poor.
Utility model content
Therefore, the technical problems to be solved in the utility model is to improve mixed effect, thus provides one can homogeneous mixture of material, the especially mixer of powder material.
To achieve these goals, a kind of mixer of the present utility model, comprise puddler, agitator tank and rotating shaft, agitator tank comprises upper cover and tank body, on be covered with charge door, rotating shaft is hollow structure, and is communicated with the puddler of hollow in tank body, rotating shaft is connected with air inlet pipe by adpting flange, and air inlet pipe is connected with positive pressure devices; The outer wall of puddler is provided with venthole; Agitator tank is provided with exhaust outlet.
Preferably, described exhaust outlet is provided with filtering plug.
Preferably, described venthole is opened in the side opposed with described agitator tank inwall of described puddler.
Preferably, described rotating shaft is fixed with the fan fin with rotating shaft coaxial rotation.
Preferably, puddler comprises cross bar connected vertically and the vertical side lever arranged with rotating shaft.
Preferably, connecting rod is connected with between rotating shaft and side lever.
Preferably, rotating shaft is coaxial with agitator tank.
Preferably, by air inlet pipe enter agitator tank for inert gas, as helium.
Preferably, described rotating shaft is connected with drive unit by driven gear.
Compared with prior art, the utility model has following beneficial effect:
1. dispel powder material by gas and make it have better mixed effect;
2. fan fin together rotates with hollow axle and causes air-swirl in tank body to drive material fully to mix;
3. for being vented, exhaust outlet ensures that in tank body, pressure can not be excessive;
4. filtering plug avoids powder material to discharge;
5. oxygen in tank is constantly discharged by the helium entering tank body, avoids material oxidized.

Detailed description of the invention
Below by way of the drawings and specific embodiments, the utility model is described in further detail.
The present embodiment provide a kind of can the mixer of homogeneous mixture of material.
As shown in Figure 1, mixer comprises air inlet pipe 1, agitator tank 2 and rotating shaft 3, air inlet pipe 1 is connected with rotating shaft 3 by adpting flange 4, agitator tank 2 comprises upper cover 5 and tank body 6, upper cover 5 is provided with charge door 7, and rotating shaft 3 is coaxial with agitator tank 2, and rotating shaft 3 to be connected with drive unit by driven gear 8 and to insert in tank body 6 through agitator tank upper cover 5, agitator tank upper cover 5 is also provided with exhaust outlet 9, and exhaust outlet 9 is provided with filtering plug 10; Rotating shaft 3 is hollow structure, is communicated with in tank body 6 with the puddler 11 of hollow, the side lever 13 that puddler 11 comprises cross bar 12 connected vertically with rotating shaft 3 and is connected with cross bar 12, and cross bar 12 and the outer wall of side lever 13 are evenly distributed with venthole 14; Connecting rod 15 is connected with between rotating shaft 3 and side lever 13; Rotating shaft 3 is also fixed with the fan fin 16 coaxial with rotating shaft 3.
Operation principle of the present utility model is: after material enters tank body 6 from charge door 7, and motor drives driven perforation 8 to rotate rear drive hollow axle 3 and rotates, and hollow axle 3 rotates and drives fan fin 16 and hollow stirrer bar 11 to rotate; Now, oxygen discharge in tank constantly prevents material oxidized by the helium entered from air inlet pipe 1, and helium blows out through the venthole 14 of hollow axle 3 from cross bar 12 and side lever 13 periphery wall, dispels powder material and makes it have good mixed effect; Meanwhile, fan fin 16 and hollow axle 3 together rotate and cause the air whirl in tank body 6 to drive material fully to mix; The helium entering tank body 6 constantly from exhaust outlet 9 discharge in case in tank body 6 pressure excessive, the filtering plug 10 at exhaust outlet 9 place avoids the discharge of powder material.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to embodiment.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And thus the apparent change of extending out or variation be still among the protection domain that the utility model creates.
