Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer filtering devices, in particular to a filtering device for producing water-soluble fertilizers. Background Art

[0002] Water-soluble fertilizer is a multi-component compound fertilizer that can be completely soluble in water. It not only has diverse formulas and can be quickly dissolved in water, but also has a high absorption and utilization rate by crops. It can also achieve water-fertilizer integration, thereby achieving the goal of saving water, fertilizer and labor.

[0003] There are solid water-soluble fertilizers and liquid water-soluble fertilizers on the market. Solid water-soluble fertilizers are easier to store and transport, so they have a large application market. When producing solid water-soluble fertilizers, impurities are inevitably produced. Therefore, the solid water-soluble fertilizers need to be filtered. However, due to the water absorption of solid water-soluble fertilizers, they are prone to caking after being damp. These lumps cannot pass through the filtering device smoothly, which will not only hinder the filtration of other solid water-soluble fertilizers, but may even cause blockage. Therefore, a filtering device that can crush lumps is needed. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] See attached Figure 1-3 A filtering device for producing water-soluble fertilizers comprises a round basin 1, a cover plate 2 is detachably mounted on the top surface of the round basin 1, a feed inlet 3 is provided on the cover plate 2, a discharge port 4 is provided in the middle of the bottom surface of the round basin 1, and a supporting assembly is provided on the bottom surface of the round basin 1; a bracket 5 is horizontally fixedly connected to the middle of the inner cavity of the round basin 1, a round flat plate 6 is placed on the bracket 5, a plurality of filter holes 7 are provided on the round flat plate 6, a plurality of protrusions 18 are formed at positions corresponding to the filter holes 7 on the top of the bracket 5, and the protrusions 18 are confined in the filter holes 7; the round flat plate 6 is fixedly connected to the top surface of the circular plate 6 with a plurality of groups of lower comb tooth rows 8, which are arranged circumferentially with the center of the top surface of the circular plate 6 as the reference; the comb teeth in each group of lower comb tooth rows 8 are arranged at equal intervals along the radial direction of the circular plate 6; a motor 9 is fixedly installed in the middle of the top surface of the cover plate 2, and the output shaft of the motor 9 passes through the cover plate 2 from top to bottom and is coaxially fixedly connected to a rotating shaft 10, and a plurality of cross bars 11 are horizontally fixedly connected to the side wall of the rotating shaft 10, and an upper comb tooth row 12 is fixedly connected to the bottom of the cross bar 11, and the upper comb tooth row 12 is staggered with the lower comb tooth row 8.

[0022] The edge of the cover plate 2 is detachably connected to the outer wall of the round basin 1 through a plurality of lock buckles 17. The lock buckles 17 are prior art and are widely used in suitcases. The feed port 3 is used to put water-soluble fertilizer with impurities and agglomerated solids into the round basin 1. The filtered water-soluble fertilizer will flow out from the discharge port 4. The support assembly can lift the round basin 1 off the ground, making it convenient for workers to collect the filtered water-soluble fertilizer under the discharge port 4. The diameter of the circular flat plate 6 is the same as the inner diameter of the round basin 1. The circular flat plate 6 can be placed horizontally in the round basin 1. The bracket 5 can support the circular flat plate 6. At least two protrusions 18 are formed on the top of the bracket 5. When the circular flat plate 6 is placed on the bracket 5, all the protrusions 18 will simultaneously extend into the corresponding filter. The hole 7 is in the middle of the filter 7, which will prevent the circular plate 6 from rotating; the size of the filter hole 7 needs to ensure that it can meet the particle size of the water-soluble fertilizer required for production, and the water-soluble fertilizer that meets the size will pass through the filter hole 7 and fall down, and the large particles of impurities will be intercepted above the circular plate 6; the rotation of the motor 9 will drive the rotating shaft 10 to rotate, the rotating shaft 10 will drive the cross bar 11 to rotate, and the cross bar 11 will drive the upper comb tooth row 12 to rotate, and the upper comb tooth row 12 can pass through the lower comb tooth row 8. For the lumps in the water-soluble fertilizer, the upper comb tooth row 12 and the lower comb tooth row 8 will squeeze and cut the lumps and crush the lumps, so that the solid water-soluble fertilizer can be turned into water-soluble fertilizer that can pass through the filter hole 7, avoiding blockage and ensuring the continuous filtration.

[0023] According to a further optimized solution, a funnel 13 is fixedly connected to the cover plate 2 at the position of the feed inlet 3 .

[0024] The funnel 13 can facilitate workers to add solid water-soluble fertilizer into the round basin 1 through the feed port 3 .

[0025] According to a further optimized solution, a pull ring 14 is fixedly connected to the middle of the top surface of the circular flat plate 6 .

[0026] The pull ring 14 can facilitate workers to take out the round flat plate 6 from the round basin 1 , and should be able to conveniently put the round flat plate 6 into the round basin 1 .

[0027] According to a further optimized solution, a plurality of handles 15 are fixedly connected to the top surface of the cover plate 2 .

[0028] The handle 15 can facilitate workers to pick up the cover plate 2 to perform other operations.

[0029] According to a further optimized solution, the support assembly includes a plurality of legs 16 fixedly connected to the bottom edge of the circular basin 1 .

[0030] The legs 16 are fixedly connected to the bottom edge of the round basin 1 along the circumferential direction, and can support the round basin 1 .

[0031] According to a further optimization scheme, the height of the middle part of the bottom surface of the circular basin 1 is lower than the height of the edge of the bottom surface of the circular basin 1 .

[0032] The middle part of the bottom surface of the round basin 1 is lower than the edge, so that the filtered solid water-soluble fertilizer can automatically gather toward the discharge port 4 and flow out from the discharge port 4 faster.

[0033] When using the utility model, first place a collection container at the bottom of the round basin 1, open the cover 2, put the round flat plate 6 into the round basin 1, and fix it on the bracket 5, cover the cover 2, start the motor 9, and then add solid water-soluble fertilizer to the round basin 1 from the feed port 3, so that the solid water-soluble fertilizer can be filtered, and the filtered water-soluble fertilizer will flow down from the discharge port 4 and fall into the collection container. After all the solid water-soluble fertilizers are filtered, open the cover 2, hold the pull ring 14 by hand, lift the round flat plate 6 out of the round basin 1, and then remove the impurities filtered on it, and then the next filtration can be carried out.
