[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances. Example
[0027] A high-speed mixer provided by the embodiment of the utility model is used for automatically discharging materials after the materials are mixed. The discharge is clean and there is no need to tilt the material tank and manual intervention, which is conducive to improving the automatic processing coverage of the equipment. In order to realize the machine structure function, the device is provided here including a frame 1. Specifically, a mixing tank 2 is provided on the frame 1. The internal rotation of the mixing tank 2 is provided with a rotary blade 3. A driving mechanism 4 for driving the rotary blade 3 to rotate is also installed on the frame 1. Figure 3As shown, the driving mechanism 4 is a motor, which indirectly drives the impeller 3 to rotate through a pulley transmission to achieve material stirring. In order to facilitate discharging, a discharge port is provided below or at the bottom of the mixing tank 2, so that after the stirring and mixing action is completed, the material inside the mixing tank 2 can be discharged from the discharge port position by opening the discharge port and the product can be collected. However, due to the design of the impeller 3 and the obstruction inside the mixing tank 2 and the small diameter of the discharge port, it is impossible to completely discharge the powdered material. A certain amount of material will remain in the mixing tank 2 and cannot be completely discharged. Therefore, a number of blowing mechanisms are also provided on the mixing tank 2, such as Figure 6 As shown, the orientation arrangement of several blowing mechanisms satisfies the requirement of having no airflow dead angle during the process from air intake at the air inlet to air discharge at the outlet, that is, the airflow inside the mixing tank 2 will provide a certain air pressure to entrain the powdered material and discharge it from the outlet position of the mixing tank 2. Since there is no airflow dead angle, the residual powdered material inside the mixing tank 2 will be effectively reduced to ensure that the product tends to be in an empty state. For the structural design of the airflow without dead angle of the blowing mechanism, no excessive restrictions are made here, and you can refer to what is described later. When emptying the material in the above manner, the pressure is first used to automatically empty a certain degree of product material, and then the last powdered material is blown out of the mixing tank 2 by blowing. There is no need for manual cooperation and dumping of the mixing tank 2. The equipment structure is simple in design, which reduces the design and production costs, and there is no need for manual cooperation to clean the material tank. The operation is convenient and conducive to automated covering operations.
[0028] A high-speed mixer provided in an embodiment of the utility model specifically provides a blowing method of a blowing mechanism. Specifically, a sealing cover 5 is provided on the top of the mixing tank 2, and a plurality of first air nozzles 7 are arranged in a circular array above the sealing cover 5. The air outlet of each first air nozzle 7 points to the inner wall of the mixing tank 2 and the blowing direction of the first air nozzle 7 is oblique to the vertical direction. Through the above design, the flow convergence expansion diagram of the air path inside the mixing tank 2 is as shown in Figure 6 As shown, the inclination angle between the first air nozzles 7 and the horizontal plane satisfies that when several first air nozzles 7 blow out airflow, an annular airflow convergence area is formed above the bottom of the inner wall of the mixing tank 2. After the airflow forms the convergence area, the powdered material on the side wall is entrained to move to the bottom wall of the mixing tank 2, and finally discharged from the discharge port. The material accumulated inside the mixing tank 2 will also move toward the discharge port along the direction of the airflow, and finally the discharge of the material product is realized.
[0029] A high-speed mixer provided in an embodiment of the utility model takes into account that if the confluence area is located too low inside the mixing tank 2, it may cause a lot of residual powdered materials above, and if the confluence area is too high, it may easily cause the airflow to be unable to fit well with the cylinder wall after being blown downward to discharge the accumulated powdered materials. Therefore, as a preferred embodiment, the highest position of the annular airflow confluence area is set here between one-third and two-thirds of the height of the mixing tank 2.
[0030] A high-speed mixer provided by an embodiment of the utility model has a plurality of second air nozzles 6 arranged in a circular array on the outer peripheral side of the mixing tank 2 in order to further enhance the effect of the airflow on entraining the powder on the inner wall of the mixing tank 2. The air outlet direction of the second air nozzle 6 points to the bottom of the mixing tank 2 and the directional path of the air path does not pass through the central axis of the mixing tank 2, so that the gas blown out by the second air nozzle 6 can also form or tend to form an annular confluence area. It should be noted that the angle between the gas blown out by the second air nozzle 6 and the first air nozzle 7 in the blowing direction is less than ninety degrees to avoid the two air flows from counteracting each other in direction. When designing, it should be noted that the position height of the discharge port needs to be lower than the position height of the second air nozzle 6 to avoid the situation where the material cannot be emptied even if an annular airflow is formed.
[0031] A high-speed mixer provided by an embodiment of the utility model can, if one wants to enhance the effect of the annular convergent gas, set the gas outlet direction of the second gas nozzle 6 to point to the inner wall of the mixing tank 2. However, if one wants to remove the powdered material remaining at the position of the rotary blade 3, set the gas outlet direction of the second gas nozzle 6 to point to the upper surface of the rotary blade 3.
[0032] A high-speed mixer provided by an embodiment of the utility model preferably has a discharge port disposed at the bottom of a mixing tank 2 in order to guide the outflow direction of an annular airflow. Specifically, the bottom surface of the inner wall of the mixing tank 2 gradually decreases in height from the edge position to the discharge port position. By designing in this way, the annular airflow will gradually move closer to the discharge port along the corresponding curved surface. In addition, powdered materials are also more likely to be discharged through the guiding surface.
[0033] A high-speed mixer provided by an embodiment of the utility model, in order to facilitate the collection of powdered materials, a device is provided here also including a material receiving box 8 connected with the material outlet through a connecting pipe 9. Specifically, an on-off valve is provided on the connecting pipe 9, and an air outlet pipe 10 is provided above the material receiving box 8. A dust collecting cloth 11 for closing the air outlet pipe 10 is provided at the position of the air outlet pipe 10. Finer powdered materials are easily lifted up and discharged from the position of the air outlet pipe 10 of the material receiving box 8. The design of the dust collecting cloth 11 can prevent the powdered materials from scattering and flying, and ensure the good collection of materials.
[0034] A high-speed mixer provided by an embodiment of the utility model, in order to enhance the effect of wind force to discharge powdered material products from the discharge port, the blades of the rotary blade 3 are arranged to be inclined to the horizontal plane. Specifically, the rotary blade 3 is designed to be able to rotate counterclockwise through the driving mechanism 4 and cooperate with the blowing mechanism to blow out the remaining material in the mixing tank 2.
[0035] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
