technical field

The utility model relates to a mixer, which belongs to the technical field of mixing equipment.

Background technique

A mixer is a machine in which a shaft with blades rotates in a cylinder or a tank to stir and mix a variety of raw materials to form a mixture or a suitable consistency. There are many kinds of mixers, such as forced mixers, single-shaft mixers, twin-shaft mixers, etc. According to the stirring method, the mixer is divided into two types: self-falling stirring and forced stirring. The self-falling mixer is to put the mixture in a rotating mixing drum. With the rotation of the mixing drum, the blades in the drum lift the mixture to a certain height, and then freely scatter it down by its own weight. This goes on over and over again until it is evenly mixed. This kind of mixer generally mixes plastic and semi-plastic concrete. In the forced mixer, the stirring drum does not move, but the blades placed on the rotating shaft in the drum are forced to stir. This kind of mixer has good mixing quality and high production efficiency; but it consumes a lot of power and the blades wear quickly, so it is generally suitable for mixing dry hard concrete. The mixing tank of the prior art utilizes the rotating shaft and the stirring rod to rotate the mixed material, such as a kind of foamed concrete mixer disclosed in Chinese utility model patent CN204295876U and a kind of feed mixer disclosed in CN204294143U. However, these mixing methods cannot make the material especially powder The material is mixed evenly, and the mixing effect is poor.

Utility model content

Therefore, the technical problem to be solved by the utility model is to improve the mixing effect, so as to provide a mixer capable of uniformly mixing materials, especially powder materials.

In order to achieve the above object, a mixer of the present utility model includes a stirring rod, a stirring tank and a rotating shaft. The mixing tank includes a top cover and a tank body. The stirring rod is connected, the rotating shaft is connected with the air inlet pipe through the connecting flange, and the air inlet pipe is connected with the positive pressure device; the outer wall of the stirring rod is provided with an air outlet; the stirring tank is provided with an exhaust port.

Preferably, the exhaust port is provided with a filter plug.

Preferably, the air outlet is opened on a side of the stirring rod opposite to the inner wall of the stirring tank.

Preferably, fan fins rotating coaxially with the rotating shaft are fixed on the rotating shaft.

Preferably, the stirring rod includes a horizontal rod vertically connected to the rotating shaft and a vertically arranged side rod.

Preferably, a connecting rod is connected between the rotating shaft and the side rod.

Preferably, the rotating shaft is coaxial with the stirring tank.

Preferably, the inert gas, such as helium, enters the stirring tank through the inlet pipe.

Preferably, the rotating shaft is connected with the driving device through a driven gear.

Compared with the prior art, the utility model has the following beneficial effects:

1. The powder material is blown away by gas to make it have a better mixing effect;

2. The fan fins rotate together with the hollow shaft to cause the air vortex in the tank to drive the materials to fully mix;

3. The exhaust port is used for exhaust to ensure that the pressure in the tank will not be too large;

4. The filter plug prevents the discharge of powdery materials;

5. The helium gas entering the tank continuously discharges the oxygen in the tank to prevent the material from being oxidized.

detailed description

The utility model is described in further detail below by means of drawings and specific embodiments.

This embodiment provides a mixer capable of uniformly mixing materials.

As shown in Figure 1, the mixer includes an air inlet pipe 1, a mixing tank 2 and a rotating shaft 3, the air inlet pipe 1 is connected to the rotating shaft 3 through a connecting flange 4, the mixing tank 2 includes an upper cover 5 and a tank body 6, and the upper cover 5 is provided with a feeding port 7, the rotating shaft 3 is coaxial with the mixing tank 2, the rotating shaft 3 is connected with the driving device through the driven gear 8 and inserted into the tank body 6 through the upper cover 5 of the mixing tank, and the upper cover 5 of the mixing tank is also provided with an exhaust port 9 to discharge The air port 9 is provided with a filter plug 10; the rotating shaft 3 is a hollow structure, and communicates with a hollow stirring rod 11 in the tank body 6, and the stirring rod 11 includes a cross bar 12 vertically connected with the rotating shaft 3 and a side bar connected with the cross bar 12 13. Air outlet holes 14 are evenly distributed on the outer walls of the cross bar 12 and the side bar 13; connecting rods 15 are connected between the rotating shaft 3 and the side bars 13; fan fins 16 coaxial with the rotating shaft 3 are also fixed on the rotating shaft 3.

The working principle of the utility model is: after the material enters the tank body 6 from the feeding port 7, the motor drives the driven gear hole 8 to rotate and then drives the hollow shaft 3 to rotate, and the rotation of the hollow shaft 3 drives the fan fin 16 and the hollow stirring rod 11 to rotate; Now, the helium gas entering from the intake pipe 1 continuously discharges the oxygen in the tank to prevent the material from being oxidized. It has a good mixing effect; at the same time, the fan fins 16 and the hollow shaft 3 rotate together to cause the gas vortex in the tank 6 to drive the materials to fully mix; the helium entering the tank 6 is continuously discharged from the exhaust port 9 to prevent the tank 6 If the internal pressure is too large, the filter plug 10 at the exhaust port 9 prevents the discharge of powdery materials.

Apparently, the above-mentioned embodiments are only examples for clear description, rather than limiting the implementation. For those of ordinary skill in the art, other changes or changes in different forms can be made on the basis of the above description. It is not necessary and impossible to exhaustively list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the scope of protection of the utility model.
