An air inlet 7 is arranged on the shell 1 at the top of the air inlet cavity 5, and an air outlet 8 is arranged at the top of the air outlet cavity 6. An air resistance plate 9 is arranged obliquely in the air inlet cavity 5, the upper end of the air resistance plate 9 is connected with the partition plate 4, and an air vent 10 is arranged between the lower end of the air resistance plate 9 and the shell 1. A flow guide plate 11 is arranged obliquely in the air outlet cavity 6, the lower end of the flow guide plate 11 is connected with the partition plate 4, and an air vent 12 is arranged between the upper end of the flow guide plate 11 and the shell 1. A material outlet pipe 13 is arranged at the bottom of the air outlet cavity 6, and a valve 14 is arranged at the bottom of the material outlet pipe 13. A plurality of baffle plates 15 are arranged on the upper surface of the air resistance plate 9, the baffle plates 15 are arranged obliquely towards the outside of the shell 1, and a material falling port 16 is arranged on the air resistance plate 9 at the side of the partition plate 4 close to the bottom of the baffle plates 15.

[0027] Further improvement, in the embodiment, the baffle plate 15 is an arc structure, which is raised towards the air inlet direction. This arc structure can better guide the airflow. The arrangement of the baffle plate 15 can also make the dust collide on the baffle plate 15 under the action of inertia, and then be discharged from the material falling port, thereby improving the dust collection efficiency.

[0028] Further improvement, in the embodiment, the air inlet 7 is arranged at one end close to the partition plate 4. Such design can make the dust-containing airflow impact on the air resistance plate 9 more directly, fully utilize the inertial force to separate the dust from the airflow, and improve the dust removal effect.

[0029] Further improvement, in the embodiment, the air outlet 8 is arranged at one end away from the partition plate 4. This is conducive to prolonging the discharge path of the purified airflow, prolonging the contact time with the flow guide plate, and thereby improving the dust removal effect.

[0030] Further improvement, in the embodiment, the lower bottom surface of the flow guide plate 11 is arranged with a plurality of baffle plates 17, which are arranged obliquely towards the direction away from the partition plate 4. The baffle plates 17 can further separate the dust still moving with the airflow after being separated by the air resistance plate 9, and improve the thoroughness of dust collection.

[0031] Further improvement, in the embodiment, the air inlet cavity 5, the air outlet cavity 6 and the material falling cavity 3 are all arranged with an inspection port 18.

[0034] The working principle of the above technical solution is as follows:

[0035] In use, the dust-containing airflow enters the air inlet cavity 5 from the air inlet 7 through a fan or other air inlet equipment. Since the air inlet 7 is close to the partition plate 4, the airflow directly impacts on the inclined air resistance plate 9 and maintains the longest contact path. During the impact process, the dust particles decrease kinetic energy due to inertia and continue to move forward and fall into the discharging cavity 3 from the discharging port 16 after colliding with the baffle one 15 on the air resistance plate 9. The airflow continues to flow forward under the guidance of the baffle one 15 and contacts the next baffle one 15 to continue the dust removal work. After the preliminary separation of the airflow by the air resistance plate 9, the airflow enters the exhaust cavity 6 through the air vent one 10. In the exhaust cavity 6, the airflow encounters the inclined guide plate 11. The baffle two 17 on the guide plate 11 performs secondary separation on the dust in the airflow. The dust collides with the baffle two 17 under the action of inertia and then slides to the bottom of the exhaust cavity 6 and is discharged through the discharge pipe 13. As the dust continuously falls into the discharging cavity 3, the dust in the discharge pipe 13 gradually accumulates. The staff can understand the accumulation of dust through the observation window 19 on the discharge pipe 13. When the dust accumulates to a certain extent, the valve 14 at the bottom of the discharge pipe 13 is opened to discharge the dust. At the same time, the inside of the equipment is checked and cleaned through the inspection hole 18 on the air inlet cavity 5, the exhaust cavity 6 and the discharging cavity 3, so as to ensure the normal operation of the equipment.

[0036] The above is only a preferred specific embodiment of the present application; however, the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and improvement concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
