Abstract
The utility model discloses a filter for producing ethlene diamine tetraacetic acid ferric ammonium salt, which comprises a pore plate, a barrel and an upper cover matched with the barrel, wherein the pore plate is arranged at the upper edge of the barrel; the upper cover is arranged on the pore plate; the barrel, the pore plate and the upper cover are connected through flanges; the barrel wall is provided with a feeding hole; the top of the upper cover is provided with a discharge hole; the bottom of the barrel is provided with a slag hole; a vertically arranged filtering rod is arranged in the barrel; and the upper end of the filtering rod is fixed on the pore plate. The utility model has the advantages that the filter has reasonable structure and can shorten the production time; due to the fact that the recyclable filtering rod is adopted, the production cost is reduced and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of filter, is a kind of production ferric ammonium ethylene diamine tetraacetate salt filter specifically.
Background technology
In the process of producing ferric ammonium ethylene diamine tetraacetate salt, can use a large amount of iron powders, and need the order number of iron powder very little, the intact iron powder of unreacted will remain in the solution like this, need remove by filter unnecessary iron powder, existing method is that unnecessary iron powder can separate with product under the help of filter aid at an easy rate, filter by filter then, when certain pressure and thickness, have very big resistance when quantitatively filter aid has adsorbed the q.s iron powder, time one is long, and filter membrane can't filter once thick.Employed in the conventional method filter is the plate compression device, and what the filtering material in this plate compression device used is disposable, though precision can reach requirement, but can not reuse, the rate of filtration is slow, has increased the production time greatly, and can increase production cost.
The utility model content
Goal of the invention: the purpose of this utility model is in order to overcome the deficiencies in the prior art, provide a kind of rational in infrastructure, can shorten the production time, reduce cost, reusable production ferric ammonium ethylene diamine tetraacetate salt filter.
Technical scheme: in order to solve the problems of the technologies described above, a kind of production ferric ammonium ethylene diamine tetraacetate salt filter described in the utility model, comprise orifice plate, staving and the loam cake that matches with staving, the orifice plate frame is at the upper limb of staving, loam cake be located at orifice plate above, staving, orifice plate and loam cake are connected by flange; Be provided with charging aperture on the bucket wall, be provided with discharging opening at the top of loam cake, be provided with slag notch in the bottom of staving, be provided with the filter stick of vertical placement in staving, the upper end of described filter stick is fixed on the orifice plate.
Described charging aperture is located at the middle and upper part of staving.
Described staving and on cover and be respectively equipped with gauge port, can protect the ability to bear of filter stick so effectively, reduce the damage probability of filter stick, and can in time grasp the time of cleaning filter stick.
Described flange comprises the lower flange that is fixed on the staving outside and is matching used and be fixed on the upper flange in the loam cake outside with lower flange, have the groove that blocks orifice plate on upper flange and lower flange.
Between described orifice plate and groove, sealing gasket is installed.
Beneficial effect: compared with prior art, the utility model has the advantages that rational in infrastructure, can shorten the production time can reusable filter stick owing to used, thus can reduce production costs, improve the efficient of producing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 be among Fig. 1 A-A to structural representation;
Fig. 3 is the partial enlarged drawing at B place among Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 3, a kind of production ferric ammonium ethylene diamine tetraacetate salt filter of the present utility model comprises orifice plate 1, staving 2 and the loam cake 3 that matches with staving 2,1 upper limb at staving 2 of orifice plate, loam cake 3 be located at orifice plate 1 above, staving 2, orifice plate 1 and loam cake 3 are connected by flange 4; Be provided with charging aperture 5 on staving 2 walls, this charging aperture 5 preferably is located at the middle and upper part of staving 2; Be provided with discharging opening 6 at the top of loam cake 3, be provided with slag notch 7 in the bottom of staving 2, be provided with the filter stick 8 of vertical placement in staving 2, filter stick 8 has a plurality of, and the upper end of every filter stick 8 is fixed on the orifice plate 1, is respectively equipped with gauge port 9 on staving 2 and loam cake 3.
Employed flange 4 comprises the lower flange 41 that is fixed on staving 2 outsides and matching used and be fixed on the upper flange 42 in loam cake 3 outsides with lower flange 41 in the utility model, on upper flange 42 and lower flange 41, have the groove 43 that blocks orifice plate 1, between orifice plate 1 and groove 43, sealing gasket 10 is installed.
During use, connect a pump at charging aperture, simultaneously slag notch is closed, to need filtered liquid to enter in the filter by charging aperture under the driving of pump and filter, filtrate enters in the next process by discharging opening then, when the needs filter rinsed, only need to block charging aperture, open slag notch, then at the logical compressed air of discharging opening, like this can be with filter residue on the filter stick by the slag notch discharge filter.
The above only is a preferred implementation of the present utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.
