DETAILED DESCRIPTION

[0021] In order to deepen the understanding of the utility model, the utility model will be further described below in conjunction with examples, and the present embodiment is only used to explain the utility model, and does not constitute the limitation to the protection scope of the utility model.

[0022] According to Figures 1-5 As shown in the figure, the present embodiment proposes a kind of impurity filtering treatment equipment in water-soluble fertilizer production process, including filter box 1, the front of filter box 1 is equipped with openable protective door, for staff to maintain the components in filter box 1.

[0023] The inside of filter box 1 is equipped with filter cartridge 2 by support, the lower part of filter cartridge 2 is conical cylinder design, and the upper end of filter cartridge 2 is equipped with drain 3, specifically, the upper end of filter cartridge 2 is equipped with water outlet 10, and water outlet 10 is integrally designed with filter cartridge 2, while the inside of water outlet 10 is equipped with annular filter screen 11, and the position of drain 3 is located above annular filter screen 11, when working, drain 3 is connected with external storage container by pipeline.

[0024] The inner side of the filter cartridge 2 is provided with a water guide assembly and an annular water delivery pipe 4, the water guide assembly comprises a hexagonal column 12, the lower end of the hexagonal column 12 is connected with the filter cartridge 2 through a sealing bearing, and the hexagonal column 12 is driven by a servo motor 13, the servo motor 13 is located at the bottom of the filter box 1 and is fixedly connected with the filter box 1 through a support, the position of the hexagonal column 12 corresponds to the middle position of the annular filter screen 11, and a stirring rod 22 is installed on the hexagonal column 12, the stirring rod 22 is provided with a plurality of groups, in the embodiment, the stirring rod 22 is provided with six groups and is distributed in a spiral upward direction, and the stirring rod 22 is concentrated on the lower part of the hexagonal column 12. Meanwhile, the top of the hexagonal column 12 is kept a certain distance from the annular filter screen 11, and the axis of the hexagonal column 12 is on the same vertical line with the center of the annular filter screen 11. When working, the servo motor 13 drives the hexagonal column 12 to rotate, so as to stir the liquid to form a spiral upward flow, thereby pushing the clean liquid to move from the bottom to the top of the filter cartridge, and strengthening the impurity separation effect. Further, in the process of moving of the clean liquid, the liquid is filtered again through the annular filter screen 11, and finally discharged through the drain port 3.

[0025] As to the annular water delivery pipe 4, the upper end (input end) thereof is fixedly connected with the filter cartridge 2, a water collecting tank 5 is installed on the inner side of the filter box 1, and the water collecting tank 5 is connected with the annular water delivery pipe 4 through a connecting pipe 6, an electric control valve is installed on the connecting pipe 6, the water collecting tank 5 is used for collecting the liquid filtered initially, and then the liquid enters the annular water delivery pipe 4 through the connecting pipe 6, and the lower end (output end) of the annular water delivery pipe 4 is directed to the inner wall of the filter cartridge, so that when the liquid enters the filter cartridge through the annular water delivery pipe 4, the liquid forms an annular flow on the inner wall of the filter cartridge, and in the process of annular flow, the larger impurities are gathered to the center of the filter cartridge due to the gravity and centrifugal force and gradually deposited to the bottom of the filter cartridge. The clean liquid is discharged through the water guide assembly. Correspondingly, the annular filter screen 11 is used for intercepting small impurities, and the larger impurities have been separated initially in the process of rotating flow and deposited to the bottom of the filter cartridge 2, so that the filtering burden of the annular filter screen 11 is greatly reduced.

[0026] Further, the inner sides of the water collecting tank 5 and the filter cartridge 2 are provided with liquid level sensors 19, which are responsible for monitoring the liquid level of the liquid in the water collecting tank 5 and the filter cartridge 2, so as to facilitate subsequent control.

[0027] The upper end of the filter box 1 is provided with a guide port 7, the guide port 7 is connected with a water-soluble fertilizer solution supply device through an external pipeline, and then the water-soluble fertilizer solution enters the filter box 1 through the guide port 7. Correspondingly, an arc-shaped filter plate 9 is arranged below the guide port 7, the arc-shaped filter plate 9 is connected with the filter box 1 through a limiting assembly, and the arc-shaped filter plate 9 is located above the water collecting tank 5. In the embodiment, the arc-shaped filter plate 9 is provided with filter holes, and the filter holes are uniformly provided with a plurality of groups, so that when the water-soluble fertilizer solution enters the filter box 1, the arc-shaped filter plate 9 performs initial filtration, part of the particles are retained in the arc-shaped filter plate 9, and the liquid enters the water collecting tank 5 through the filter holes.

[0028] Furthermore, the limiting component includes two sets of symmetrically arranged arc-shaped tracks 14, which are fixedly connected to the arc-shaped filter plate 9. Wheels 15 are distributed on both sides of the arc-shaped tracks 14, and several sets of wheels 15 are provided, distributed as follows: Figure 1 As shown, the distribution of the track wheels 15 follows the curvature of the arc-shaped track 14, which is adapted to the curvature of the arc-shaped filter plate 9. The corresponding track wheels 15 are connected to the filter box 1 via the support frame 16. Figure 3 As shown in this embodiment, two sets of guide wheels 15 are installed on a set of support frames 16, and the cross-section of the arc-shaped track 14 is L-shaped, so its shorter end passes exactly between the two sets of guide wheels 15. Therefore, under the action of the guide wheels 15 and the arc-shaped track 14, the position and movement path of the arc-shaped filter plate 9 can be limited.

[0029] The filter box 1 has an opening 20 at the top, which can accommodate the arc-shaped filter plate 9. The position of the opening 20 corresponds to the position of the arc-shaped filter plate 9. The arc-shaped filter plate 9 is equipped with a hanging ear 21. During use, foreign objects may remain on the arc-shaped filter plate 9, which needs to be cleaned to restore its filtration performance. Therefore, during this process, the staff can use an external traction tool to hook the hanging ear 21 to pull out the arc-shaped filter plate 9 for cleaning, and then put it back.

[0030] Correspondingly, the filter box 1 is provided with two sets of symmetrically arranged baffles 17. A buffer pad 18 is installed on the baffle 17. The buffer pad 18 contacts the arc-shaped filter plate 9. The buffer pad 18 contacts the arc-shaped filter plate 9, which plays a buffering role and can also limit the installation position of the arc-shaped filter plate 9.

[0031] Both sides of the lower part of the filter cartridge 2 are equipped with drain ports 8, and each drain port 8 is also equipped with an electric control valve. Under the control of the staff, foreign objects in the filter cartridge 2 are periodically discharged.
