[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0022] Example 1: As Figures 1-4As shown, this utility model provides an airflow pulverizing nozzle mechanism, including an air intake main pipe 1. A main nozzle mechanism 3 is fixedly connected to the end of the air intake main pipe 1. The main nozzle mechanism 3 includes a first connector 31, which is fixedly connected to the air intake main pipe 1. A first nozzle 32 is fixedly connected to the end of the first connector 31, and a first nozzle 33 is fixedly connected to the end of the first nozzle 32. An air intake branch pipe 4 is fixedly connected to the side of the air intake main pipe 1. An auxiliary nozzle mechanism 5 is fixedly connected to the end of the air intake branch pipe 4. The auxiliary nozzle mechanism 5 includes a second connector 51, which is fixedly connected to the end of the air intake branch pipe 4. A second nozzle 52 is fixedly connected to the end of the second connector 51, and the second nozzle 52 is fixedly connected to the end of the second connector 51. The main nozzle 32 is fixedly connected to a second nozzle 53. The second nozzle 52 consists of two sections: a straight tube and a horn tube. One end of the straight tube is fixedly connected to a second connector 51, and the other end of the straight tube is fixedly connected to the horn tube. The end of the horn tube is fixedly connected to the second nozzle 53. The first nozzle 32 is provided with rifling 34 inside. There are eight rifling 34 inside the first nozzle 32. The eight rifling 34 are evenly distributed inside the first nozzle 32. Two auxiliary nozzle mechanisms 5 are provided on the side of the main nozzle mechanism 3. The two auxiliary nozzle mechanisms 5 are symmetrically distributed on both sides of the main nozzle mechanism 3. The auxiliary nozzle mechanisms 5 are inclined on the side of the main nozzle mechanism 3. The inclination angle of the auxiliary nozzle mechanisms 5 on the side of the main nozzle mechanism 3 is 30°-45°.
[0023] The specific settings and functions of this embodiment are described in detail below. High-speed airflow is introduced into the first nozzle 32 through the air intake pipe 1. At this time, the rifling 34 inside the first nozzle 32 will cause the airflow introduced into the first nozzle 32 to rotate. At this time, the airflow ejected from the first nozzle 33 will drive the granular material to rotate and collide. The high-speed airflow will pass through the air intake branch pipe 4 and then be ejected through the second nozzle 52 and the second nozzle 53. The second nozzle 52 accelerates the airflow, so that the airflow velocity from the second nozzle 53 and the first nozzle 33 is different. This results in the granular material having different velocities during crushing. At this time, the granular material will collide with each other, improving the efficiency of granular material crushing.
[0024] Example 2: Figure 1 As shown, an electrically controlled valve 2 is installed on the surface of the main intake pipe 1. The electrically controlled valve 2 is located between the connection between the main nozzle mechanism 3 and the main intake pipe 1 and the connection between the intake branch pipe 4 and the main intake pipe 1.
[0025] The overall effect of this embodiment is that the air intake airflow inside the main nozzle mechanism 3 is controlled by the electronically controlled valve 2, thereby adjusting the air intake volume of the air intake branch pipe 4, which facilitates the adjustment of the air intake volume of the main nozzle mechanism 3 and the auxiliary nozzle mechanism 5, and facilitates the control of the airflow speed of the first nozzle 33 and the second nozzle 53, thereby enabling the crushing of different particulate materials.
[0026] The working principle of this utility model is as follows: a high-speed airflow is introduced into the No. 1 nozzle 32 through the air intake pipe 1. At this time, the rifling 34 inside the No. 1 nozzle 32 will cause the airflow introduced into the No. 1 nozzle 32 to rotate. At this time, the airflow ejected from the No. 1 nozzle 33 will drive the particulate material to rotate and collide.
[0027] At the same time, the high-speed airflow will pass through the intake branch pipe 4 and then be ejected through the second nozzle 52 and the second nozzle 53. The second nozzle 52 accelerates the airflow, so that the airflow velocity from the second nozzle 53 is different from that from the first nozzle 33, thus the granular material has different speeds when it is crushed.
[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
