[0002] The mixing device of mechanical stirring will generate heat by friction and also break the product while stirring the mixed material, which will affect the product quality and increase the power loss. The airflow mixer in the prior art solves the above problems. The airflow mixer uses the compressed air sprayed from the bottom as kinetic energy. After entering the mixing bin, the pressure is quickly released to make the material tumble, activate, convect and diffuse to achieve high uniformity mixing. The kinetic energy of the air is cleaned and discharged through the top filter. The airflow mixer is widely used in the production of medicines and food.

[0003] According to the search, the patent with the patent publication number CN212188890U discloses a pulse airflow mixer. The pulse airflow mixer includes a bin, a mixer, a discharge valve and a filter. The top of the bin is provided with an inlet and a filter. The bottom of the bin is conical. The mixer is installed at the bottom end of the bin. The discharge valve is installed below the mixer. The sidewall of the bin is provided with an inlet. The mixer includes a base and multiple air blowers. The base is detachably fixed to the bottom of the bin. The middle of the base is provided with a conical channel penetrating through the upper and lower ends of the base. The conical channel is matched with the bottom of the bin. The multiple air blowers are distributed and installed on the sidewall of the conical channel of the bin. The air outlet of the air blower faces the inside of the bin.

[0029] The inside of discharge gate 2 is fixed with electric telescopic rod 7 through connecting frame, the telescopic end of electric telescopic rod 7 is fixed with pressure reducing cone 6, the lateral wall of pressure reducing cone 6 is sealingly connected with the inner wall of discharge gate 2, the lateral wall of discharge gate 2 is provided with multiple universal air injection heads 8, one end of universal air injection head 8 is connected with the inner wall of discharge gate 2 through telescopic protective sleeve, and one end of universal air injection head 8 is towards pressure reducing cone 6 and has an included angle A with the axis of pressure reducing cone 6, the included angle A is greater than 0 degrees and less than 90 degrees, the lateral wall of discharge gate 2 is provided with drive cavity, the inner wall of drive cavity is rotatably connected with gear ring 10, the other end of multiple universal air injection heads 8 is fixedly connected with gear ring 10, the gear ring 10 is drivingly engaged with gear 11 on one side, and the motor for driving gear 11 to rotate is installed on the lateral wall of discharge gate 2, the electromagnetic valve 9 is installed on one side of discharge gate 2, the air outlet end of electromagnetic valve 9 is communicated with one end of multiple universal air injection heads 8, and the other end of electromagnetic valve 9 is communicated with external air source.

[0030] During mixing, solenoid valve 9 opens, and external gas is sprayed onto pressure reducing cone 6 through universal jet head 8. The gas then rises spirally along the inner wall of mixing tank 1, blowing the raw materials upwards for mixing. Solenoid valve 9 then closes, and the raw materials accumulate at outlet 2 due to gravity, completing one pulse mixing cycle. During mixing, connecting rod 16 can be rotated to move sealing plug 17 away from mixing tank 1. At this time, sampling cylinder 12 is connected to mixing tank 1, allowing raw materials inside mixing tank 1 to enter sampling cylinder 12.

When not sampling, the sealing plug 17 seals the sampling cylinder 12 to prevent the raw material from entering the sampling cylinder 12. In order to better mix different raw materials, the motor drives the gear 11 to rotate, which drives the gear ring 10 to rotate. This allows one end of the universal jet head 8 to rotate around the axis of the decompression cone 6, changing the degree of the included angle A, which can better mix different raw materials.

[0031] With the sampling component 5, sampling can be performed without stopping the machine, which makes it easy to determine the mixing of raw materials. At the same time, the sealing plug 17 can seal the sampling cylinder 12 when sampling is not in progress, preventing raw materials from entering the sampling cylinder 12.

[0032] By setting up the universal jet head 8, the gear ring 10 and the gear 11, the angle A between one end of the universal jet head 8 and the axis of the pressure reducing cone 6 can be adjusted as needed to control the flow path of the airflow and better mix different raw materials.
