Description

Technical Field

[0001] This utility model relates to the technical field of fertilizer filtration devices, specifically to a filtration device for the production of water-soluble fertilizers. Background Technology

[0002] Water-soluble fertilizers are a type of high-efficiency fertilizer widely used in modern agricultural production, and the filtration process during production is crucial for ensuring product quality. During the production of water-soluble fertilizers, the raw materials often contain various impurities and insoluble substances, which need to be effectively separated through filtration devices to ensure the solubility and efficacy of the final product.

[0003] In the production of water-soluble fertilizers, the raw material solution often contains undissolved particles, crystals, and packaging residues, among other solid impurities. Existing filtration equipment mostly uses a single-layer filter structure, which has the following drawbacks: low filtration efficiency: a single mesh size filter cannot simultaneously intercept large particles and remove fine impurities, leading to incomplete filtration or frequent clogging; downtime for cleaning: impurities accumulate and require periodic shutdowns for manual scraping of the filter screen, severely hindering continuous production. Therefore, a filtration device is needed that can filter impurities of different sizes without requiring downtime for cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a filtration device for the production of water-soluble fertilizers to solve the problems mentioned in the background art.

[0006] Furthermore, a vibrator is fixedly installed at both the left and right ends of the coarse filter and the fine filter.

[0007] Furthermore, the upper end of the side wall of the filter housing is provided with symmetrical upper discharge ports, the lower end of the upper discharge ports is provided with symmetrical upper collection troughs fixed to the side wall of the filter housing, the lower end of the side wall of the filter housing is provided with symmetrical lower discharge ports, and the lower end of the lower discharge ports is provided with symmetrical lower collection troughs fixed to the side wall of the filter housing.

[0008] Furthermore, a feeding port is provided through the upper end of the side wall of the filter housing.

[0009] Furthermore, a liquid outlet pipe is provided through the lower end of the side wall of the filter housing.

[0010] Furthermore, the vibrating column includes two sets of spring columns fixed between the upper support block and the coarse filter screen, and also includes four sets of piston columns fixed between the upper support block and the coarse filter screen.

[0011] This utility model has the following beneficial effects:

[0012] The beneficial effects of this utility model are as follows: By setting up a filter structure with two layers of filter screens of different mesh sizes, the coarse filter screen can intercept larger particles of impurities, while the fine filter screen can filter out fine impurities, effectively filtering impurities of different sizes and solving the problem that a single mesh size filter screen cannot simultaneously intercept large particles of impurities and remove fine impurities; the motor-driven rotating shaft drives a soft brush to clean the surface of the filter screen, and the vibrator causes the filter screen to vibrate, causing impurities to be discharged through the upper and lower discharge ports and collected in the upper and lower collection troughs respectively, without the need to stop the machine to clean the impurities, solving the problem of needing to stop the machine periodically to manually scrape off the accumulated impurities on the filter screen in the prior art, which is conducive to achieving continuous production; at the same time, the design of the vibrating column enhances the vibration effect of the filter screen, further improving the impurity removal efficiency and ensuring the continuity and stability of water-soluble fertilizer production.

[0030] A symmetrical lower discharge port 6 is provided through the lower end of the side wall of the filter housing 9. The lower discharge port 6 is located 20 mm below the fine filter screen 3 and is rectangular. A symmetrical lower collection trough 5 is provided below the lower discharge port 6 and fixed to the side wall of the filter housing 9. The lower collection trough 5 is made of stainless steel and is used to collect small particulate impurities after being filtered by the fine filter screen 3.

[0031] A feeding port 18 is provided through the upper end of the side wall of the filter housing 9. The feeding port 18 is used to feed the water-soluble fertilizer raw material to be filtered into the filter device.

[0032] A liquid outlet pipe 4 is installed through the lower end of the side wall of the filter housing 9.

[0035] The working principle of this filtration device for water-soluble fertilizer production is as follows: The water-soluble fertilizer raw material to be filtered is fed into the filtration device through the feed port 18. The raw material first passes through the coarse filter screen 2, which filters out larger impurities. These impurities are discharged through the upper discharge port 8 and collected in the upper collection tank 7. The liquid after being filtered by the coarse filter screen 2 continues to flow downward and undergoes secondary filtration through the fine filter screen 3. The fine filter screen 3 filters out smaller impurities. These impurities are discharged through the lower discharge port 6 and collected in the lower collection tank 5. Finally, the filtered water-soluble fertilizer liquid is discharged through the liquid outlet pipe 4.

[0036] During the filtration process, motor 1 drives shaft 16 to rotate, and the crossbar 15 and soft brush 14 on shaft 16 also rotate accordingly. The soft brush 14 cleans impurities from the surface of fine filter screen 3, preventing clogging. Simultaneously, the vibrator 17 generates vibration, causing both coarse and fine filter screens 2 and 3 to vibrate, accelerating impurity separation and improving filtration efficiency. The spring column 1201 and piston column 1202 in the vibrating column 12 buffer the vibration, preventing excessive vibration from damaging the equipment.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
