Description

Technical Field

[0001] This application relates to the field of fertilizer production, and in particular to a fertilizer filtering and impurity removing mechanism. Background Art

[0002] Chemical fertilizers refer to fertilizers produced by chemical synthesis methods, which provide essential nutrients for plant growth, such as nitrogen, phosphorus, potassium, etc. Due to their high efficiency and quick-acting characteristics, chemical fertilizers are widely used in modern agriculture;

[0003] In the process of producing chemical fertilizers, there will be large raw materials that have not fully participated in the reaction, by-products generated during the production process of chemical fertilizers, and pollutants accidentally mixed in during the production of chemical fertilizers, such as plastic fragments, paper scraps, etc. The presence of these solid impurities will reduce the proportion of the effective components of the chemical fertilizers, resulting in a decrease in the actual nutritional value of the chemical fertilizers. Therefore, it is necessary to filter and remove solid impurities in the chemical fertilizers during production. Traditional chemical fertilizer impurity filtering equipment often filters impurities through a single screening device, which cannot effectively remove impurities of different sizes, which may lead to incomplete removal of impurities and affect the quality of chemical fertilizers. Moreover, due to the uneven size of impurity particles, filtering together with chemical fertilizer particles is likely to cause the screen to become blocked. Frequent blockages will reduce production efficiency and increase the workload of maintenance. Utility Model Content

One side of the baffle 6 is rotatably provided with a rotating plate 9 through a rotating shaft, and the other side of the baffle 6 is slidably provided with a moving plate 7. A first sieve mesh 12 is fixed below the baffle 6. The baffle 6, the moving plate 7, and the rotating plate 9 form a rectangular frame with the same top size as the first sieve mesh 12, so that the chemical fertilizer will not splash outside the first sieve mesh 12 during sieving. There is an impurity removing opening 13 on the impurity removing box 1 for a first inclined plate 14 to pass through, and a first inclined plate 14 is rotatably provided on one side of the first sieve mesh 12. The chemical fertilizer to be impurity removed enters the first sieve mesh 12 in the impurity removing box 1 through the feeding cylinder 24. The swing plate 4 drives the baffle 6 and the first sieve mesh 12 to reciprocate up and down along the vertical direction of the through opening. After one sieving is completed, the rotating plate 9 is rotated to filter out the impurities through the first inclined plate 14.

[0028] Refer to Figure 1 , 2 , A filtering hopper 19 is fixed in the impurity removing box 1. The filtering hopper 19 is located below the first sieve mesh 12. The bottom of the inner wall of the filtering hopper 19 is inclined with a second sieve mesh 20. One side of the filtering hopper 19 corresponding to the inclined low end of the second sieve mesh 20 is provided with a second inclined plate 21. The chemical fertilizer sieved from the first sieve mesh 12 falls onto the inclined second sieve mesh 20 through the filtering hopper 19 for further filtering. The inclined second sieve mesh 20 can accelerate the rolling of the chemical fertilizer on the surface of the second sieve mesh 20. The chemical fertilizer that has passed the filtering on the second sieve mesh 20 is discharged through the second inclined plate 21.

[0029] Refer to Figure 2 , The mesh holes of the first sieve mesh 12 are larger than those of the second sieve mesh 20. The first sieve mesh 12 is used to screen out large particle impurities in the chemical fertilizer, and the second sieve mesh 20 is used to screen out powdery impurities in the chemical fertilizer, removing impurities of different sizes and improving the purity and uniformity of the chemical fertilizer.

[0030] Refer to Figure 1 , 3, 5. There are sliding grooves formed at the tops of both baffles 6.

The scraping plate 17 can accelerate the cleaning of impurities on the surface of the first sieve 12. The rolling of the cleaning roller 18 enables the protrusions thereon to clean the mesh holes of the first sieve 12, avoiding the blockage of the mesh holes, reducing the wear and damage of the first sieve 12, and reducing the frequency of replacement and cleaning.

[0031] Refer to Figure 1 , 4 , two support frames 2 are fixed to the top of the impurity removal box 1.

The guide cone 26 helps to disperse the aggregated chemical fertilizer, reducing the blockage of the first sieve 12 caused by the accumulation of chemical fertilizer. The spiral guide vane 25 can ensure that the chemical fertilizer is evenly distributed on the sieve surface of the first sieve 12, avoiding local overload and improving the impurity filtering efficiency.

[0033] Refer to Figure 5 , a rotating block 10 is fixed to one side of the rotating plate 9. An electric push rod 11 is fixed to one side of the baffle 6.

[0036] The implementation principle of a fertilizer filtering and impurity removing mechanism in an embodiment of the present application is as follows: the chemical fertilizer to be impurity-removed is put into the feeding cylinder 24. Under the combined action of the guiding blades 25 and the guiding cone 26, the chemical fertilizer is evenly distributed on the screen surface of the first screen 12. The motor 1 is started to drive the swinging frame 3 to drive the swinging plate 4 and the first screen 12 to swing, so as to filter impurities from the chemical fertilizer on the first screen 12. After one screening movement is completed, the electric push rod 11 is started to make its telescopic end push the rotating block 10, so that the rotating plate 9 rotates and opens, so that the large-particle impurities screened out are filtered through the first inclined plate 14. At the same time, the motor 8 is started to make the moving plate 7 and the scraping plate 17 and the cleaning roller 18 thereon move towards the rotating plate 9, accelerating the removal of impurities and cleaning the screen surface of the first screen 12 at the same time. The chemical fertilizer sifted from the first screen 12 falls onto the inclined second screen 20 through the filter hopper 19 for further filtration. The qualified chemical fertilizer screened above the second screen 20 flows into the collecting box 22 through the second inclined plate 21, and the debris sifted through the second screen 20 falls into the debris box 23. The box door 27 is opened to process the chemical fertilizer in the collecting box 22 and the debris in the debris box 23.
