Abstract
The utility model relates to a filtering device of silted acid. The filtering device comprises a groove body with an opening in the top; a liquid discharging hole is formed in the bottom of the rear part of the groove body; the middle part of the groove body is provided with a first filtering plate used for dividing the groove body into a front part and a rear part; filtering holes with the hole diameter being 3-6mm are formed in the first filtering plate; the middle parts of the two side walls of the groove body are provided with first grooves for installing the first filtering plate. By arrangement of the filtering device, large-particle impurities can be intercepted by the filtering plate when the silted acid passes, so that the purification of acid liquor is realized; by adoption of an inserting mode for installing the filtering plate, the operation is very convenient.
Description
Technical field
The utility model relates to a kind of device filtering being delivered to the phosphoric acid,diluted of phosphoric acid,diluted storage tank for Wet-process Phosphoric Acid Production.
Background technology
The source of the raw material phosphoric acid,diluted of MAP mainly contains two kinds, and one is common phosphoric acid,diluted, and a kind of is the silt acid that contains a large amount of large granular impurities.Usually, raw material phosphoric acid,diluted directly enters phosphoric acid,diluted storage tank by pipeline.For the acid of becoming silted up, owing to containing large granular impurity in silt acid, the particle diameter great little ≤6mm of part particle.If easily stop up MAP slip nozzle and subsidiary pipeline for directly producing MAP, cause production system unstable, thereby affect the normal production of MAP, and easily damage the required moving equipment of producing.
Summary of the invention
The purpose of this utility model is to provide a kind of phosphoric acid,diluted filter, can reduce the large granular impurity of what acid, thereby reduces the obstruction of MAP slip nozzle and subsidiary pipeline, improves the stability of production system.
The utility model has adopted following technical scheme: the cell body that comprises upper opening, bottom, cell body rear portion is provided with outage, two-part the first filter plate before and after cell body middle part is provided with cell body is separated into, on the first filter plate, be distributed with the filtering holes of aperture at 3～6mm, the middle part of two sidewalls of cell body is provided with the first slot that the first filter plate is installed.In the time becoming silted up acid process cell body, wherein large granular impurity is held back by the first filter plate, purifies thereby realize acid solution.
Further, the second filter plate that cell body middle part is also provided with the second slot and coordinates with the second slot in the first slot one side, is distributed with the filtering holes consistent with the first filter plate aperture on the second filter plate.By changing filter plate, can realize process units and move continuously, can clean in time the filter plate of obstruction simultaneously, improve filter effect.
The mistake liquid of considering filter plate is unobstructed, and preferred, the aperture of described filtering holes, at 4～5mm, can guarantee that filter plate is crossed liquid unobstructed, can effectively prevent that again bulky grain from entering in the production of MAP.
As shown from the above technical solution, the utility model is by filter is set, and the acid of becoming silted up can be held back by filter plate through out-of-date large granular impurity, purifies thereby realize acid solution.And two filter plate rotations are filtered, and both can realize process units and move continuously, can clean in time again the filter plate of obstruction, improve filter effect.In addition, adopt plug-in mounting mode that filter plate is installed, easy to operate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises that the cell body 1 of upper opening and the first filter plate 4, the second filter plate 5(being arranged in cell body 1 are dotted portion in Fig. 1), cell body 1 is rectangle, and the middle part of two sidewalls of cell body 13,14 is provided with the first slot 6 and the second slot 7 that two filter plates are installed.The first filter plate 4 has the consistent filtering holes in aperture with the second filter plate 5 surface distributed, and the aperture of filtering holes, at 3～6mm, is preferably 4～5mm.First, second filter plate 4,5 height are lower than cell body 10～15cm, and in the time that filter plate is not cleared up, silt acid can not overflow cell body yet, but overflow is to cell body rear portion 12.
The first filter plate 4 shown in Fig. 1 and Fig. 2 is inserted in the first slot 6, and cell body 1 is separated into forward and backward two parts 11,12.12 bottoms, cell body rear portion are provided with outage 3, communicate with phosphoric acid,diluted storage tank by pipeline.Acid inlet tube 2 outlets communicate with cell body front portion 11.The acid of becoming silted up passes into cell body front portion 11 by acid inlet tube 2, and when by the first filter plate 4, large granular impurity can be held back by filter plate, and the silt acid that enters cell body rear portion 12 is entered in the phosphoric acid,diluted storage tank that is arranged on cell body 1 below by outage 3 and pipeline.
In the time that the first filter plate 4 need to clean, first the second filter plate 5 is inserted in the second slot 7, then takes out the first filter plate 4 and clean.Now, the second filter plate 5 will be separated into forward and backward two parts 11,12 by cell body 1, and in Renewal process, in silt acid, large granular impurity is held back by filter plate all the time, does not need to close acid inlet tube, thereby can realize process units and move continuously.
