Description

Technical Field

[0001] This utility model belongs to the field of phosphate rock processing technology, and in particular relates to a phosphate rock slurry filtration device. Background Technology

[0002] my country has abundant phosphate rock reserves, but high-grade phosphate rock reserves are low and expensive. Most of the phosphate rock used in phosphate chemical production is of medium to low grade.

[0003] The mined phosphate rock needs to be crushed and ground to break large pieces of ore into a suitable size for processing. Then, the ore is ground into finer particles through the grinding process to facilitate the separation of minerals from gangue.

[0004] The crushed phosphate rock is then subjected to flotation. The flotation slurry is then filtered through a filter medium to separate the phosphogypsum and phosphoric acid.

[0005] Existing filtration methods typically involve feeding slurry into a filter box, where it is then filtered through a filter screen. However, small particles of phosphate rock and impurities continuously settle at the bottom of the filter box after filtration, making them difficult to clean. The continuous flow of slurry further impacts these deposited particles, causing them to settle again and further reducing the filtration efficiency. Additionally, the filter screen inside the box cannot be cleaned or replaced promptly.

[0006] Therefore, a phosphate rock slurry filtration device is needed to reduce the secondary impact of deposited particles, while also facilitating the cleaning of the bottom of the filter box and enabling timely replacement of the filter screen. Utility Model Content

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See Figures 1-3 This utility model provides a technical solution:

[0025] like Figures 1-3 As shown, a phosphate slurry filtration device includes a filter box 1 and a filter plate 2 located inside the filter box 1. The bottom of the filter box 1 is provided with a corrugated bottom plate, which includes a plurality of adjacently arranged recesses 11 and protrusions 12. Each protrusion 12 corresponds to a filter plate 2, and the filter plate 2 is inserted into the protrusion 12. The filter box 1 is provided with a liquid inlet pipe 13 at one end perpendicular to the filter plate 2, and a liquid outlet pipe 14 at the other end of the filter box 1.

[0026] Through the above technical solution, a wavy bottom plate is formed by multiple adjacent recesses 11 and protrusions 12. When the slurry enters from the inlet pipe 13, it is filtered through the frontmost filter plate 2. The impurities filtered out at this time will remain in the recesses 11 at the front end of the protrusions 12. At the same time, the sediment in the recesses 11 is unlikely to affect the filter plate 2 located above the protrusions 12, thus ensuring the filtration of the filter plate 2 and reducing secondary filtration of sediment. At the same time, the slurry filtered on one side will undergo a second filtration. Similarly, the impurities filtered out will fall into the recesses 11 at the front end of the filter plate 2, which can effectively collect and deposit the impurities, avoiding affecting the filtration of the upper protrusions 12. When the slurry passes through the last filter plate 2, it will pass through the recesses 11 again. The recesses 11 here have a settling function until the slurry can flow out from the rear discharge pipe.

[0027] The slurry can be effectively filtered by the corrugated bottom plate and multiple filter plates 2 located in the raised part 12. At the same time, it can ensure that the filtered impurities settle into the recessed part 11, reduce the secondary filtration of impurities, and improve the overall filtration effect of the filter box 1.

[0028] Furthermore, the filter box 1 is provided with sliding grooves 17 on the left and right sides corresponding to the filter plate 2, and the protrusion 12 is provided with a slot 16 on the bottom of the filter plate 2. The filter plate 2 is engaged with the filter box 1 through the sliding grooves 17 and the slot 16. The top of the filter plate 2 is provided with a handle 22.

[0029] Through the above technical solution, the filter plate 2 can be easily removed from the slide groove 17 and the slot 16 for cleaning or replacement by lifting the filter plate 2, thereby improving the filtration effect of the filter plate 2.

[0030] Furthermore, the inner wall of the slot 16 is provided with a first snap-fit ​​strip on both sides, and the filter plate 2 is provided with a second snap-fit ​​strip on the upper and lower sides corresponding to the first snap-fit ​​strip.

[0031] Through the above technical solution, the first and second snap-fit ​​strips can be snapped together to ensure the seal between the filter plate 2 and the slot 16. The first and second snap-fit ​​strips can be made of rubber material, and the snap-fit ​​structure can be easily removed or inserted.

[0032] Furthermore, each of the recesses 11 has an inlet 31 on one side and an outlet 32 ​​on the other side.

[0033] The recessed portion 11 can be flushed through the inlet 31, thereby flushing out impurities inside the recessed portion 11 and discharging them from the outlet 32 ​​on the corresponding side, reducing the accumulation of impurities and affecting filtration.

[0034] Furthermore, a flushing port 33 is provided on one side of the card slot 16, and a drain port 34 is provided on the other side of the card slot 16.

[0035] With the above technical solution, after the filter plate 2 is lifted, the groove 16 can be rinsed through the flushing port 33 to remove the impurities remaining in the groove 16, and then discharged from the drain port 34 after rinsing.

[0036] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
