This utility model belongs to the field of filtration device technology, specifically relating to the field of filtration technology for processing nitrogen-containing liquid fertilizer. Background Technology

[0002] Liquid fertilizer, or liquid fertilizer for short, mainly includes clear liquid type and suspension type. In my country, the main type of liquid fertilizer is clear liquid fertilizer. For example, ammonium phosphate solutions of different concentrations are produced by neutralizing liquid ammonia with phosphoric acid, superphosphoric acid, and polyphosphoric acid. This is a very common type of liquid fertilizer. If other nitrogen fertilizers, potassium chloride, and medium and trace elements are dissolved in appropriate proportions, multi-element liquid compound fertilizers can be produced. Some fertilizers need to be fermented by biological enzymes. These liquid fertilizers contain a certain amount of residue, so they need to be filtered during processing. Currently, most filtration devices on the market are prone to poor residue discharge during use, which can easily lead to blockage. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution:

[0019] A filtration device for processing nitrogen-containing liquid fertilizer through bio-enzyme fermentation includes a mounting box 1. A feed inlet 2 is installed at the top of the mounting box 1, and a drain outlet 3 is installed on the side of the mounting box 1. A filter screen 4 is installed inside the mounting box 1 between the feed inlet 2 and the drain outlet 3. Material is added into the mounting box 1 through the feed inlet 2, and the filtrate falls through the filter screen 4 and is then discharged through the drain outlet 3. A slag-guiding mechanism 6 is installed inside the mounting box 1 at a position corresponding to the surface of the filter screen 4 to clean the residue on its surface. A slag outlet 5 is installed on the side of the mounting box 1 at a position corresponding to the slag-guiding mechanism 6. Residue remaining on the surface of the filter screen 4 is discharged through the slag outlet 5 under the action of the slag-guiding mechanism 6, thereby preventing the filter screen 4 from becoming clogged.

[0020] Above the slag discharge port 5 inside the installation box 1, a slag brush 7 is installed to clean the residue on the slag guiding mechanism 6. This allows the slag brush 7 to scrape off the residue on the slag guiding mechanism 6 and then let it fall into the slag guiding pipe 9 through the slag guiding plate 10.

[0021] A switch 8 and a motor 13 are installed on the side of the mounting box 1. The slag guiding mechanism 6 includes a main shaft 14 and a secondary shaft 17 installed inside the mounting box 1. A conveyor belt 15 is sleeved on the outside of the main shaft 14 and the secondary shaft 17. The output shaft of the motor 13 passes through and extends into the interior of the mounting box 1 and is connected to the main shaft 14. Brush bristles 16 are distributed on the outside of the conveyor belt 15. The bottom end of the brush bristles 16 is interference-fitted with the surface of the filter screen 4. The secondary shaft 17 passes through and extends to the outside of the mounting box 1. A gear 23 and a pulley 18 are sleeved on the outside of the secondary shaft 17 outside the mounting box 1. The motor 13 drives the main shaft 14 to rotate, thereby driving the conveyor belt 15 to rotate, which in turn drives the brush bristles 16 to move, thereby cleaning the residue on the filter screen 4, so that the residue can be quickly moved to the position of the slag discharge port 5.

[0022] The brush holder 7 includes a mounting shaft 20 installed inside the mounting box 1. Brush bristles 21 are distributed on the outside of the mounting shaft 20. The mounting shaft 20 extends through and to the outside of the mounting box 1 and is connected to a gear 22. The gear 22 and the gear 23 are meshed and connected, so that when the main shaft 14 rotates, it can drive the gear 23 to rotate. Under the transmission of the gear 22, the mounting shaft 20 is driven to rotate, thereby enabling the brush bristles 21 to rotate, which facilitates the cleaning of the residue carried on the brush bristles 16.

[0023] The filter screen 4 is tilted, with the end of the filter screen 4 near the feed inlet 2 positioned higher. The slag guiding mechanism 6 is equipped with a slag guiding pipe 9 at the lower position of the filter screen 4. A raised platform is provided at the contact point between the filter screen 4 and the slag guiding pipe 9. This not only ensures that the solution can flow smoothly on the filter screen 4, but also prevents the solution from entering the slag guiding pipe 9. The residue can also be easily moved to the slag discharge port 5 by the action of the slag guiding mechanism 6. The slag guiding pipe 9 has an opening at the position corresponding to the slag brush frame 7, and a slag guiding plate 10 is installed at the opening. The residue will splash under the action of the brush bristles 21, and the slag guiding plate 10 will block the splashed residue.

[0024] The slag guide pipe 9 is equipped with a screw conveyor frame 11. The drive shaft inside the screw conveyor frame 11 runs through and extends to the outside of the mounting box 1 and is connected to a pulley 12. The pulley 12 is connected to the pulley 18 via a belt 19. Thus, when the main shaft 14 rotates, the screw conveyor frame 11 is driven to rotate through the pulley 12, belt 19 and pulley 18, thereby facilitating the rapid discharge of residue.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
