Air mixer

In order to overcome the traditional mixer's complex structure, small mixing capacity, high energy consumption and other shortcomings, our company and partners recently developed a pulse-typeAir mixer。 The new pulse-type air mixer has the characteristics of high mixing efficiency, fast mixing, large scale, low energy consumption, no dead angle and easy maintenance.

One: Structure

The new type of pulse air mixer mainly consists of filter, silo, mixing head, discharging valve and other main components.

Design Structure Description:

1 Mixer Filter: Used for external pulse dust remover (also can maintain atmospheric pressure with the external atmosphere), when the material through pneumatic conveying to the mixing machine, through the hopper filter will exhaust the excess gas. The filter is equipped with a pulse reverse blow to prevent buildup of material.

2 Filter: Starting Material gas separation function.

3 Feeding port: Reserved for people to feed the station or the use of pipeline transportation.

4 Mixing head: Mixing head and mixer of the spray device, depending on the pulse valve repeatedly cycle alternately to the mixing bin blowing gas, so that the material in the warehouse vulcanization, to achieve the purpose of mixing.

5 discharge valve: A conical valve is installed at the bottom of the mixer, and the cone valve is opened through the cylinder when discharging, and the material flows out from the conical valve. The material can be injected into the storehouse by the mixer blowing device, and the material flow is accelerated so that the material flows out quickly to prevent the aggregate.

6 pressure tester, emptying valve: If the pressure detector detects high pressure in the warehouse (≥5-10KPA) affects the airflow mixing effect, the emptying valve opens the pressure relief.

Two: Features

1) Fast mixing speed

General powder (powder) materials only need to run 3~5 mixing cycle.

A batch of materials mixed evenly in just a few minutes.

2 The mixer has no mechanical transmission parts

No mechanical transmission parts, equipment running without friction heat, no lubricant pollution products, the damage to the material is very small (particle crushing degree ≤1‰), mixing can be very good to protect the properties of the material.

3 Strong Applicability

Materials from dozens of kg to several tons can be quickly mixed evenly mixed, very suitable for large, super large powders for a short time uniform mixing. Suitable for pesticide, medicine, dyestuff, food and other industries powder mixing.

4 Low energy consumption

Unit energy consumption is about 20%~30% 5 of mechanical mixer Unit energy consumption simple

The whole mixing process is controlled by PLC. Remote control is also available on demand. installation, operation, maintenance are very convenient.

Three: Working principle

The equipment has compressed air Station gas supply, air flow in pulse mode through the mixing head nozzle into the silo, compressed gas along the cone-shaped discharge valve cone wall spiral up, the material by the spiral of compressed gas impact, as the compressed gas spiral rise, expansion, and then the material began to settle, a pulse cycle after the end of the second cycle opened, In turn, the flow of compressed gas into the silo, the gas driven material tumbling to make the material evenly mixed. After mixing the gas is processed by the filter to return to the atmosphere. After the mixture is complete, open the cone discharging valve to discharge the material. There is a certain intermittent time between the pulses, the number of pulses and the intermittent time of the pulses are determined by the properties of the materials.

Four: Characteristic parameter

1 Compressed air operating pressure : 0.2~0.6mpa (material-like)

2) Mixing time : 3~5min

3) Load factor : 0.4~0.6

4 working pressure of mixed warehouse : micro-negative pressure

5) Mixing bin emptying valve opening pressure: 5~10kpa

6) Ash cleaning method for mixed warehouse : Pulse Back blow

7) Air source pressure of ash cleaning : 0.3~0.6mpa

8 air consumption of ash-cleaning gas source : 0.15m³/min

9) Material : SUS304

V: General operation

Initialization pulse: After starting the first spray cycle, clear the cone-type valve low aggregate.

Feed end delay: After the feed end, there is no residue in the feed pipeline, delay can make the residual in the pipeline complete release.

Discharge valve interval: On the discharge valve has open state to close, after the time, the release valve opened to ensure that there is no material in the cylinder, the time for the discharge valve interval.

Discharge delay: After the material is finished, the cone-shaped valve has material residue at the bottom, which requires further finishing treatment, which is the time for discharging.

The vibration, intermittent, action times and the above values are specified according to the actual requirements.

Reverse blowing: When discharging, the reverse blowing can accelerate the discharging speed.

Single-Cycle homogenization:

Each pulse valve action time: Each pulse valve opens to the shutdown time.

Interval: The time before the first valve is closed to the second valve opening. (need to be greater than the reverse blow

Set the time, the reverse blow only takes effect)

Frequency of each valve action: In principle 1~9 can be set. For example: When set to 2 o'clock,

1, 2 action → 2, 3 action → 3, 4 action ... →9, 10 action →10, 1 action

(a cycle).

When set to 3 o'clock, 1, 2, 3 action → 2, 3, 4 action → 3, 4, 5 action ...

→8, 9, 10 action →9, 10, 1 action →10, 1, 2 action (one cycle).

Combined homogenization mode:

A total of 10 pulse valves, the action is the first 10 full action, the second Action 1, 2, 3, 4, 5 half of the pulse valve, the third action of the other half pulse valve, the last 10 full action. The first to fourth time of the moving time and interval can be set. (The interval should be greater than the time of the reverse blowing setting, the time interval of the reverse blowing is effective, on the contrary, it does not work.) ）

Combined Homogenization method: The cycle of two sets of cycles is superimposed on the cycle of the method.

Work cycle: is set the number of cycles, in short, there are several cycles running.
