Abstract
The utility model discloses a pressure filter for an ammonium molybdate solution, which comprises a bracket. The pressure filter for the ammonium molybdate solution is characterized in that a pressure filter shell is supported on the bracket; the upper end of the pressure filter shell is fixedly connected with a flange seat; a filter element is inserted into the pressure filter shell; a mounting flange is arranged at the upper end of the filter element; the mounting flange is fixedly connected with the flange seat; the mounting flange is fixedly connected with a solution outlet pipe; and a solution inlet pipe is arranged at the lower end of the pressure filter shell. The pressure filter for the ammonium molybdate solution has the advantages that the filtration speed is quick; the work efficiency is high; the filtration speed is more than four times as quick as that of an original suction filtration way; the filtration precision is high; the product quality is good; micro insoluble substances with grain sizes more than 0.2 [mu]m can be completely intercepted; the clarity of a filtrate is good; the service life is long; the service life of the filter element can reach ten years; and filtering cloth and filtering paper do not need to be replaced and only need to be reversely washed periodically, so that the pressure filter is quick and convenient in use.
Description
Technical field
The utility model is particularly related to a kind of ammonium molybdate solution pressure filter.
Background technology
Ammonium molybdate solution is to carry out the preceding body solution that acid is sunk and then produced ammonium molybdate crystal, and its clean level is directly connected to the credit rating of ammonium molybdate crystal product.At present common way is with still aging 48 hours of ammonium molybdate solution, then by being covered with the vacuum suction filter groove suction filtration of filter cloth filter paper in the industry.This method rate of filtration is slow, inefficiency, because the hole of filter paper filter cloth can be out of shape greatly, causes filtering accuracy not high, even usually owing to filter paper damages the filter phenomenon takes place to run, and causes filtrate clarity not enough, and product ammonium molybdate crystal credit rating descends.
Summary of the invention
Technical problem to be solved in the utility model is to provide that a kind of rate of filtration is fast, efficient is high, and filtering accuracy height, good product quality need not to change the ammonium molybdate solution pressure filter of filter cloth filter paper.
The utility model is achieved in that it has a support, in the support upper support pressure filter housing is arranged, be connected with flange seat in pressure filter housing upper end, in the pressure filter housing, be inserted with filter core, be provided with mounting flange in the filter core upper end, mounting flange and flange seat are affixed, are connected with drain pipe on mounting flange, are provided with feed tube in the lower end of pressure filter housing.
Above-mentioned ammonium molybdate solution pressure filter, the bottom of described pressure filter housing are back taper.
Above-mentioned ammonium molybdate solution pressure filter, described filter core are compound porous filter core between titanium aluminium.
Above-mentioned ammonium molybdate solution pressure filter is connected with adpting flange respectively on feed tube and drain pipe.
Above-mentioned ammonium molybdate solution pressure filter is provided with sealing gasket between mounting flange and flange seat, to guarantee the sealing effectiveness of pressure filter housing.
The utility model has the advantages that: the rate of filtration is fast, high efficiency, and the rate of filtration is more than 4 times of original suction filtration mode; Filtering accuracy height, good product quality can be held back the above micro-insoluble matter of 0.2 μ m fully, and filtrate clarity is good; Long service life, filter element life can reach 10 years, need not to change filter cloth filter paper, only needs the periodic reverse flushing to get final product, and is efficient and convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: adpting flange 1, drain pipe 2, mounting flange 3, flange seat 4, filter core 5, pressure filter housing 6, annular gap 7, support 8, feed tube 9, sealing gasket 10.
The specific embodiment
As shown in the figure, the utility model has a support 8, and is affixed and be supported with cylindrical shape pressure filter housing 6 on support 8, is connected with flange seat 4 in pressure filter housing 6 upper ends, the bottom of pressure filter housing 6 is a back taper, is connected with feed tube 9 in the center, lower end of pressure filter housing 6.Be inserted with filter core 5 in pressure filter housing 6, described filter core 5 is a compound porous filter core between titanium aluminium, forms annular gap 7 between filter core 5 and the pressure filter housing 6.Be welded with mounting flange 3 in filter core 5 upper ends, mounting flange 3 is pressed on the flange seat 4 and is affixed by bolt with flange seat 4, is provided with sealing gasket 10 between mounting flange 3 and flange seat 4, to guarantee the sealing effectiveness of pressure filter housing 6.Be connected with drain pipe 2 in mounting flange 3 upper surface centers, on feed tube 9 and drain pipe 2, be connected with adpting flange 1 respectively.
During work, the adpting flange 1 of this pressure filter by feed tube 9 ends is connected with the press filtration pump.Ammonium molybdate solution is squeezed into pressure filter housing 6 via the press filtration pump by feed tube 9 after the ageing, and clear liquid enters filter core 5 by annular gap 7 under the effect of pressure, and the insoluble matter of trace is trapped, and clear liquid is discharged by drain pipe 2 and entered the heavy operation production high-quality ammonium molybdate of acid.
