Abstract
The utility model discloses a filtering plate and relates to filtering equipment. The filtering plate comprises a filtering plate body, wherein the filtering plate body is provided with horn holes; the big hole of each speaker hole faces upwards; pinholes are formed in the lateral surface of each speaker hole and communicated with the lower surface of the filtering plate body; convex ribs are arranged on the inner wall of each speaker hole; the convex ribs are vertically arranged. The filtering plate is simple in structure and reasonable in design; by utilizing the pinholes formed in the speaker holes, the filtering plate can still conveniently take a filtering effect after small impurities block up the speaker holes; the convex ribs take an effect of keeping off impurities, so that gaps are formed between the impurities and the walls of the speaker holes; the filtering plate is convenient to filter a mixture, is simple and practical, avoids the phenomenon that a filter screen is blocked, and has the obvious effects.
Description
Technical field:
The utility model relates to a kind of filter plant, is specifically related to a kind of filter.
Background technology:
Existing filter is to be equipped with hole on a filter plate, and mixture filters by hole, but such filter type often occurs impurity in mixture, blocks filter opening, causes mixture to filter, poor filtration effect.
Utility model content:
Technical problem to be solved in the utility model is to overcome the defect of prior art, provides a kind of simple in structure, a kind of filter of good filtration effect.
Technical problem to be solved in the utility model realizes by the following technical solutions.
, it is characterized in that: comprise a filter plate, filter plate is provided with bellmouth orifice, upward, described bellmouth orifice side is provided with pin hole and passes to filter plate lower surface bellmouth orifice macropore, and described bellmouth orifice inwall is provided with fin, and fin vertically arranges.
Described fin cross section is triangle.
The utility model is simple in structure, reasonable in design, after utilizing pin hole that bellmouth orifice is provided with can facilitate small impurities to block horn mouth, still can play the effect of filtration, impurity is blocked in the effect of fin, make to have gap on impurity and loudspeaker hole wall, facilitate mixture to filter, simple and practical, the situation of having avoided filter screen to block, successful.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model;
Wherein: 1: filter plate; 2: bellmouth orifice; 3: pin hole; 4: fin.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
A kind of filter as shown in Figure 1, comprises a filter plate 1, and filter plate 1 is provided with bellmouth orifice 2, upward, bellmouth orifice 2 sides are provided with pin hole 3 and pass to filter plate 1 lower surface bellmouth orifice 2 macropores, and bellmouth orifice 2 inwalls are provided with fin 4, fin 4 vertically arranges, and fin 4 cross sections are triangle.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
