[0023] Embodiment 1

[0024] The present embodiment is a granular filtering device for chemical production, which is used for separating the granules and impurities carried by the granules in chemical production, hereinafter referred to as granules.

[0025] From the structure, the core structure of the present embodiment is a containing cylinder 1, and the separation and filtering of the granules and impurities are carried out in the containing cylinder 1. Specifically, the containing cylinder 1 of the present embodiment includes a cylinder body, an air inlet pipe 4, a feed pipe 5 and a discharge pipe are installed on the cylinder body. As a more specific embodiment, the air inlet pipe 4 and the feed pipe 5 can use the same inlet, and the air inlet pipe 4 and the feed pipe 5 are connected together through a three-way pipe. An upper filter plate is installed on the upper end of the cylinder body, and a lower filter plate is installed on the lower end of the cylinder body. The pore size of the lower filter plate is smaller than the diameter of the granules, and the pore size of the upper filter plate is also smaller than the diameter of the granules. From the material, the cylinder body of the present embodiment is of metal material, and the filter plate material is also different according to the different granule materials, for example, PP plastic granules can be matched with PP plastic filter plate. In addition, a valve is installed on the discharge pipe, which is closed when the air is inhaled to avoid the leakage of the granules from the discharge pipe. In addition, when discharging or unloading, the valve is opened, and the granules are blown out of the discharge pipe by a stronger airflow. It should be noted that the amount of granules fed into the containing cylinder 1 is one-half to two-thirds of the volume of the containing cylinder 1, which ensures that more than half of the granules are blown out when discharging.

[0026] As the airflow related structure for cleaning away the impurities, the upper end of the containing cylinder 1 of the present embodiment is provided with an air inlet channel 10, and the lower end of the containing cylinder 1 is provided with an air outlet channel. From the flow direction, the airflow flow direction of the air inlet channel 10 of the present embodiment is perpendicular to the airflow flow direction of the air inlet pipe 4. From the structure, the air inlet channel 10 is in the shape of a cone or a circular truncated cone, and the upper end cross-sectional area of the air inlet channel 10 is smaller than the lower end cross-sectional area of the air inlet channel 10.

[0027] As a connecting structure, the embodiment is provided with an upper connecting plate 6 between the containing cylinder 1 and the air inlet channel 10, and a lower connecting plate 8 between the containing cylinder 1 and the air outlet channel. The upper end of the cylinder body is provided with an upper wing plate 2, and the lower end of the cylinder body is provided with a lower wing plate 3. The upper wing plate 2 is fixedly connected with the upper connecting plate 6, and the lower wing plate 3 is fixedly connected with the lower connecting plate 8. The fixed connection scheme adopts bolted connection. The connecting plate has a sealing function, so as to avoid air leakage at the connection. In addition, according to different requirements, the connecting plate can also have some functions, for example, dense nylon nets are installed on the lower connecting plate 8, and impurities are gradually hung on the nylon nets, so as to collect the impurities.

[0028] As a sealing structure of the connecting plate, the upper end and the lower end of the upper connecting plate 6 are provided with upper sealing strips 7. The upper end of the air inlet channel 10 and the upper end of the cylinder body are provided with grooves, and the upper sealing strips 7 are arranged in the grooves. The upper end and the lower end of the lower connecting plate 8 are provided with lower sealing strips 9. The lower end of the air outlet channel and the lower end of the cylinder body are provided with grooves, and the lower sealing strips 9 are arranged in the grooves.

[0029] The principle of the filtration of the embodiment is as follows: the filtration of particles generally has two schemes. The first scheme is to use a vibrating screen or the like to screen, but it is difficult to remove the impurities on the surface of the particles. The second scheme is water washing, but the particles need to be dried after water washing, which takes a long time and uses a large amount of water. In the embodiment, the airflow of the air inlet pipe 4 blows the particles in the feeding pipe 5 into the containing cylinder 1, the airflow of the air inlet pipe 4 blows the particles to move and separates the particles from the impurities. Under the action of the airflow of the air inlet channel 10, the impurities are carried out along the air outlet channel, and the particles are blocked by the filter plate on the cylinder body, so as to separate the particles from the impurities.

[0030] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0031] The above describes the specific embodiments of the present application in combination with the drawings, but is not a limitation on the protection scope of the present application. Those skilled in the art should understand that various modifications or changes made on the basis of the technical solutions of the present application without creative labor are still within the protection scope of the present application.
