Fig. 1 is a schematic structural diagram of an ethanol-free mother powder mixing device, as shown in fig. 1, and referring to fig. 2 to 5, an embodiment of the present invention provides an ethanol-free mother powder mixing device, which includes a first air outlet mechanism 100, a second air outlet mechanism 200, a third air outlet mechanism, and a feeding mechanism.

The first air outlet mechanism 100 is configured to generate an air flow to the right and form a first air curtain 140. The second air outlet mechanism 200 is located below the first air outlet mechanism 100, and is configured to generate a rightward air flow and form a second air curtain 240. The third air outlet mechanism is disposed between the first air outlet mechanism 100 and the second air outlet mechanism 200. The third air outlet mechanism is used to generate a rightward air flow and form a feed air flow 320. The feed mechanism is used to direct the material to be mixed into the feed air stream 320.

Specifically, the material to be mixed is a powdery material. Further, the first air curtain 140 and the second air curtain 240 are air flow walls formed by air flows, which can block the mixed materials, and meanwhile, the air flows of the first air curtain 140 and the second air curtain 240 can fully mix the materials to be mixed.

Further, the space between the first air curtain 140 and the second air curtain 240 is a mixing area, and the materials to be mixed are conveyed rightward under the driving of the feeding airflow 320 in the mixing area, and are fully mixed under the action of the airflows of the first air curtain 140 and the second air curtain 240.

Further, the air flow of the first air curtain 140, the air flow of the second air curtain 240, and the feeding air flow 320 collide with each other during the rightward blowing, so that local vortex or turbulence is generated, thereby enabling the materials to be mixed to be sufficiently mixed.

In operation, the first air outlet mechanism 100, the second air outlet mechanism 200 and the third air outlet mechanism are respectively started, so that the first air outlet mechanism 100 forms a first air curtain 140, the second air outlet mechanism 200 forms a second air curtain 240, and the third air outlet fan is configured to feed air flow 320.

The feeding mechanism guides the materials to be mixed into the feeding airflow 320, and the materials to be mixed are driven by the feeding airflow 320 to convey the materials to the right to the mixing area between the first air curtain 140 and the second air curtain 240. When the material contacts upward with the first air curtain 140, it is blocked by the air flow wall of the first air curtain 140. As the material contacts the second curtain 240 downward, it is blocked by the flow wall of the second curtain 240. The mixed materials are fully fused in the mixing area under the combined action of the air flows of the first air curtain 140 and the second air curtain 240 and the feeding air flow 320.

In some embodiments of the present invention, the ethanol-free mother powder mixing device further comprises a fourth air outlet mechanism and a fifth air outlet mechanism. The fourth air outlet mechanism is used for generating rightward air flow and forming a third air curtain, the third air curtain is vertically arranged and is positioned at the front side of the mixing area, the fifth air outlet mechanism is used for generating rightward air flow and forming a fourth air curtain, and the fourth air curtain is vertically arranged and is positioned at the rear side of the mixing area.

In some embodiments of the present invention, as shown in fig. 1, the ethanol-free master batch mixing apparatus further comprises a collection chamber 600, a return air duct 500, and an air supply device 400. The collecting cavity 600 is disposed on the right sides of the first air outlet mechanism 100, the second air outlet mechanism 200 and the third air outlet mechanism, and is used for receiving the mixed materials. The air supply device 400 is used for delivering air flow into the first air outlet mechanism 100, the second air outlet mechanism 200 and the third air outlet mechanism.

One end of the return air duct 500 is communicated with the collecting cavity 600, and the other end is communicated with the inlet of the air supply device 400, and the return air duct 500 is used for redirecting the air flow in the collecting cavity 600 into the inlet of the air supply device 400.

Specifically, the right ends of the first air outlet mechanism 100, the second air outlet mechanism 200 and the third air outlet mechanism are downstream sides of the feeding airflow 320, and the collecting cavity 600 is communicated with the mixing area, so that the feeding airflow 320 conveys the mixed materials into the collecting cavity 600 for aggregation.

Further, the material continuously enters the collecting chamber 600 along with the feeding airflow 320, and the pressure in the collecting chamber 600 is continuously increased, so that the pressure in the collecting chamber 600 can be balanced by the arrangement of the return air pipe 500. Meanwhile, the air in the collecting cavity 600 enters the return air pipe 500 to generate air flow, and the air flow is reintroduced into the third air supply mechanism along with the return air pipe 500 and enters the mixing area along with the air supply mechanism again, so that the air flow is fused into the feeding air flow 320, and the effect of energy recovery is achieved.

Specifically, the air supply device 400 can supply air to the first air outlet mechanism 100, the second air outlet mechanism 200 and the third air outlet mechanism continuously, so that air flows are generated in the first air outlet mechanism 100, the second air outlet mechanism 200 and the third air outlet mechanism continuously.

In some embodiments of the present invention, as shown in fig. 1 and 2, the sidewall of the collection chamber 600 is provided with a vent 610, and at least the vent 610 is covered with a filter cloth 620. One end of the return air duct 500 communicates with the air discharge hole 610.

Specifically, the arrangement of the filter cloth 620 can filter the material, preventing the material from following the air flow into the return air duct 500.

In some embodiments of the present invention, as shown in fig. 1, a drying mechanism 510 and a humidifying mechanism 520 are disposed in the return air duct 500, and the humidifying mechanism 520 is used to humidify the air flow flowing through the return air duct 500, so as to remove materials entrained in the air flow. The drying mechanism 510 is located on the right side of the humidifying mechanism 520 in the direction of airflow, and is used for drying the airflow.

Specifically, the humidifying mechanism 520 is configured to humidify the air flow in the return air pipe 500, so that the materials in the air flow can be precipitated, and backflow is prevented from entering the mixing cavity along with the air flow.

Further, after the air flow with larger humidity enters the mixing cavity, the humidity of the material to be mixed can be increased, so that the material to be mixed is settled, and the material mixing efficiency is further affected. Therefore, the drying mechanism 510 is configured to dry the air flow, so that the wet air flow can be prevented from entering the mixing cavity to affect the humidity of the material to be mixed, thereby achieving the effect of improving the mixing efficiency of the material.

In some embodiments of the present invention, the inlet of the air supply device 400 is also in controlled communication with the outside to prevent air replenishment when the amount of air is insufficient. The return air pipe 500 is also provided with an exhaust valve to prevent the internal pressure from being too high, and can exhaust redundant gas when the pressure in the return air pipe 500 is too high.

In some embodiments of the present invention, as shown in fig. 1, the air outlet of the first air outlet mechanism 100 and the air outlet of the second air outlet mechanism 200 can be rotatably disposed within a preset angle, so as to change the included angle between the first air curtain 140 and the second air curtain 240, so that the right end of the first air curtain 140 and the right end of the second air curtain 240 are close to or far from each other, or synchronously rotate upwards or synchronously rotate downwards. Similarly, the air outlet of the fourth air outlet mechanism and the air outlet of the fifth air outlet mechanism can be rotatably arranged within a preset angle.

Specifically, in the initial state, the first air curtain 140 and the second air curtain 240 are horizontally arranged, and when the first air outlet mechanism 100 and the second air outlet mechanism 200 rotate, the first air curtain 140 and the second air curtain 240 can be continuously close to or continuously far away from each other, so that the first air curtain 140 and the second air curtain 240 repeatedly extrude the mixed materials, and the mixing efficiency of the materials can be improved.

Further, the right end edge of the first air curtain 140 and the right end edge of the second air curtain 240 are close to each other, so that the mixing cavity can be drawn into a necking structure. The air flow of the first air curtain 140 and the air flow of the second air curtain 240 in the state of the necking structure are more likely to collide with the feeding air flow 320 to generate vortex, and the mixing effect of the materials under the action of the vortex can be further improved. Meanwhile, the necking structure can continuously gather materials in the process that the feeding airflow 320 drives the materials to be conveyed rightwards, so that the mixing effect of the materials is improved.

Further, in some embodiments of the present invention, when the first and second air curtains 140, 240 are proximate to each other, the third and fourth air curtains are distal from each other. When the first and second air curtains 140 and 240 are apart from each other, the third and fourth air curtains approach each other.

Further, the rotational speeds of the first air outlet duct 120 and the second air outlet duct may be set to be different or the same.

Specifically, the first air outlet barrel 120 and the second air outlet barrel reciprocally rotate within a preset angle to perform turbulence in the mixing area, and the turbulence can perform full mixing and stirring on materials.

When the air conditioner works, the first air outlet 120 drives the first air outlet 121 to rotate downwards, and the second air outlet drives the first air outlet 121 to rotate upwards. The first air outlet duct 120 rotates at a speed greater than or less than or equal to the second air outlet duct.

The spiral case of the cross flow fan is rotationally arranged, the rotation axis of the spiral case is coaxial with the axis of the wind wheel, and the installation of the cross flow wind wheel and the motor is not required to be changed, so that the adjustment of the air outlet direction is realized.
