Abstract
The utility model discloses a composite filter structure for preventing secondary pollution of a medicinal plate-and-frame filter press. The composite filter structure comprises a bracket, a left cover board and a right cover board, wherein the left cover board and the right cover board are fixed on the bracket; a plurality of filter plates and filter frames are arranged between the left cover board and the right cover board; filter cloth is arranged between the filter plates and the filter frames; a liquid inlet is formed in the middle of the upper end of each filter frame; a liquid outlet is formed in the middle part of the lower end of each filter frame; a square sinks in the middle of each filter frame; a convex edge is formed at the periphery of the square; a bump matched with the concave square in the middle of each filter frame is formed in the middle of each filter plate; a concave edge matched with the convex edge is formed at the periphery of the bump; a round filter point and a plurality of support points are arranged on the filter surface of each filter plate; a plurality of pressure-relief vents are arranged between the support points. The filter plates and the filter frames disclosed by the utility model are tightly matched, the displacement when a filter chamber is large in pressure is reduced, secondary pollution is reduced, and the filtering quality is ensured; the support points are added to the filter plates, so that the filter plates can support each other, and are unlikely to deform or damage; the pressure-relief vents are additionally formed, so that the internal stress can be removed; the filtering speed is increased due to the round filter points.
Description
Technical field
The utility model relates to medicinal filter, and what say especially is the combined filtration structure of the medicinal plate and frame filter press of a kind of anti-secondary pollution.
Background technology
Plate and frame type filter-press is filter plant comparatively advanced in current pharmaceutical industry.Plate and frame filter press is the one group of filter chamber consisting of the filter plate of alternative arrangement and filter frame, by hold down gag, clamps sheet frame, by feed pump, suspension is pressed into filter chamber, on filter cloth, form filter residue, until be full of filter chamber, filtrate, through filter cloth and along filter plate trench flow to sheet frame corner passage, is concentrated and is discharged.Existing this plate and frame type filter-press is because the secret room pressure of filter plate and filter frame formation is excessive, the situation that filter frame may be subjected to displacement, so pressure leaks from surrounding, causes secondary pollution, affect filter quality, simultaneously also there is poor filtration effect, the shortcoming such as perishable in filter plate.
Utility model content
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of combined filtration structure of the medicinal plate and frame filter press of anti-secondary pollution of good filtration effect.
Technical approach of the present utility model is to provide the combined filtration structure of the medicinal plate and frame filter press of a kind of anti-secondary pollution, comprise support and be fixed on left cover, the right cover plate on support, between left cover and right cover plate, be provided with several filter plates and filter frame, it is characterized in that: between filter plate and filter frame, filter cloth is housed, described filter frame upper center is provided with inlet, middle part, filter frame lower end is provided with liquid outlet, described filter frame medial recess one square, and form chimb in square surrounding; The middle part of described filter plate is set to a projection matching with the square of filter frame medial recess, forms the concave edge mating with chimb in protruding surrounding, and the filtering surface of filter plate is provided with circular filtered points, some supporting-points, is provided with a plurality of vents between supporting-point.
The utility model has the advantages that: filter plate of the present utility model closely matches with filter frame, the displacement situation that minimizing filter chamber pressure occurs when large, avoids occurring secondary pollution, has guaranteed filter quality; Filter plate increases supporting-point, can mutually support, not yielding, damaged, increases vent, can eliminate internal stress, circular filter point, and the rate of filtration is accelerated.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2 is filter frame structural representation described in the utility model.
Fig. 3 is filter-plate structure schematic diagram described in the utility model.
The specific embodiment
Now by reference to the accompanying drawings, the utility model is further described.
As shown in Figure 1, the combined filtration structure of the medicinal plate and frame filter press of a kind of anti-secondary pollution, comprise support 1 and be fixed on left cover 2, the right cover plate 3 on support 1, between left cover 2 and right cover plate 3, be provided with several filter frames 4 and filter plate 5, it is characterized in that: between filter frame 4 and filter plate 5, filter cloth 6 is housed, described filter frame 4 upper center are provided with inlet 7, filter frame 4 middle parts, lower end are provided with liquid outlet 8, described filter frame 4 medial recess one squares 9, and form chimb 10 in square surrounding; The middle part of described filter plate 5 is set to a projection 11 matching with the square 9 of filter frame 4 medial recess, surrounding in projection 11 forms the concave edge 12 mating with chimb 10, the filtering surface of filter plate 5 is provided with circular filtered points 13, some supporting-points 14, is provided with a plurality of vents 15 between supporting-point 14.
