Embodiment Construction
[0020] Such as figure 1 As shown, the filter device according to the present invention is a structure of a filter box 100. The specific technical solution is that there is a rectangular box body with a movable cover 101 on the top, a feeding port 102 on one side of the box body, a discharge port 103 on the bottom of the box body, and a filter screen with a certain slope installed inside the box body The net 10 plays a role of separating liquid and solid, and the upper part of the filtering screen 10 is connected to a platform 20 for storing impurities.
[0021] The working principle is that the solution enters the filter box 100 through the feed inlet 102, and flows out of the outlet 103 after being filtered through the filter screen 10, while the impurities remain on the platform 20 of the filter screen. The impurities are caused by the pressure of the feed solution. Flush upwards and accumulate, flush to the platform 20 before cleaning.
[0022] In one embodiment, the filter sc...

The invention discloses a filtering device and a solution filtering method therefor. The filtering device is characterized in that the filtering device comprises a filtering tank with a removable cover; a filter screen is arranged in the filtering tank with the removable cover and divides the filtering tank with the removable cover into an upper filtering space and a lower filtering space; the upper filtering space is communicated with a material inlet located on a side of the filtering tank with the removable cover; the lower filtering space is communicated with a material outlet located on the bottom of the filtering tank with the removable cover; the filter screen comprises a platform part and an inclined part; the inclined part of the filter screen is provided with multiple filtering apertures; at least one part of the filtering apertures have elongated shapes; and a longitudinal symmetric line of each one of the filtering apertures having elongated shapes forms an acute angle with an intersecting line of the filter screen and the side which belongs to the filtering tank with the removable cover and is provided with the material inlet. The filtering device prevents that impurities are stuck in a screen mesh easily, realizes easy removal of impurities, has a simple structure, is convenient for use, avoids that mechanical impurities are introduced by follow-up production processes, and improves product quality.
Description
Technical field [0001] The present invention relates to a filtering device and a solution filtering method. In particular, the present invention relates to a filter box that removes mechanical impurities from the solution before entering the production equipment to separate solid and liquid. Background technique [0002] There are usually large impurity particles in the raw material solution, such as thread ends. Before entering the subsequent production equipment, the solution needs to remove mechanical impurities to separate the solid and liquid, that is, a screen needs to be designed to filter large particles of impurities. [0003] Ordinary filter screens are grid-shaped, and impurities are easily stuck in the screen; and ordinary filter screens are placed horizontally, and impurities cannot be concentrated in one place. Therefore, the cleaning of impurities is inconvenient. Summary of the invention [0004] The purpose of the present invention is to provide a filtering device, ...
