Abstract
The utility model belongs to the technical field of detection, and relates to a fixture used for testing the filter efficiency of a plane filtering material. The fixture is characterized by consisting of an upper shell (1), a lower shell (2), a support screen plate (3) and a connecting bolt, wherein the inner surface (1a) of the upper shell (1) is provided with a coaxial cylindrical upper shell groove (1d); the lower shell (2) is a round plate with the diameter equal to the diameter of the upper shell (1), an the inner surface (2a) of the lower shell is provided with a lower shell step groove; the support screen plate (3) is a circular plate provided with dense through holes on the surface; and the support screen plate (3) is positioned between the upper shell (1) and the lower shell (2). The fixture can be used for testing the filter efficiency of the plane filtering material, and is simple in structure as well as convenient and fast for use.
Description
Technical field
The utility model belongs to the detection technique field, relates to a kind of anchor clamps that the filtration efficiency of plane filter material is tested.
Technical background
The unit clamp of also the filtration efficiency of filtering material not being tested at present can't be tested the filtration efficiency of filtering material.
Summary of the invention
The purpose of this utility model is: a kind of simple in structure, easy to use, the test fixture that can test the filtration efficiency of plane filter material is provided.
The technical solution of the utility model: plane filter material filtration efficiency test fixture is characterized in that it is made up of upper shell, lower house, support web plate and coupling bolt; Upper shell is a circular slab, a coaxial cylindrical upper shell groove is arranged on the surface within it, bottom land at the upper shell groove has the center to connect threaded hole, port at the upper shell groove has the annular boss that exceeds inside surface, has 3～6 to connect upper shell bolts hole upper shell, that be uniformly distributed along the circumference near the close circumference of upper shell; Lower house is a circular slab with the upper shell equal diameters, a coaxial cylindrical lower house stepped recesses is arranged on the surface within it, in abutting connection with the lower house inside surface is the major diameter groove, in abutting connection with the major diameter groove is the minor diameter groove, bottom land at the minor diameter groove has the center to connect threaded hole, near the close circumference of lower house, connect lower house bolt hole lower house, that be uniformly distributed along the circumference, the quantity of lower house bolt hole is identical with the upper shell bolt hole and the position is corresponding, the external diameter of the annular boss of upper shell and lower house major diameter groove clearance fit; Supporting web plate is the plectane that a surface has intensive through hole, percentage of open area is not less than 80%, support the internal diameter of the external diameter of web plate less than lower house major diameter groove, greater than the internal diameter of lower house minor diameter groove and greater than the internal diameter of upper shell groove, support the port that web plate is sealed on lower house minor diameter groove, the end face of upper shell annular boss will support web plate and compress, and coupling bolt is connected to integral body with upper shell and lower house.
The utility model has the advantages that: can finish the filtration efficiency of plane filter material is tested, simple in structure simultaneously, easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Be in the synoptic diagram of separated position among the figure for each parts, omitted coupling bolt.
Embodiment
Below the utility model is described in further details.Referring to Fig. 1, plane filter material filtration efficiency test fixture is characterized in that, it is made up of upper shell 1, lower house 2, support web plate 3 and coupling bolt; Upper shell 1 is a circular slab, a coaxial cylindrical upper shell groove 1d is arranged on the surperficial within it 1a, bottom land at upper shell groove 1d has the center to connect threaded hole 1e, port at upper shell groove 1d has the annular boss 1b that exceeds inside surface 1a, has 3～6 to connect upper shell bolt hole 1c upper shell 1, that be uniformly distributed along the circumference near upper shell 1 close circumference; Lower house 2 is the circular slabs with upper shell 1 equal diameters, a coaxial cylindrical lower house stepped recesses is arranged on the surperficial within it 2a, in abutting connection with lower house inside surface 2a is major diameter groove 2b, in abutting connection with major diameter groove 2b is minor diameter groove 2d, bottom land at minor diameter groove 2d has the center to connect threaded hole 2e, at lower house 2 near connecting lower house 2 near the circumference, the lower house bolt hole 2c that is uniformly distributed along the circumference, the quantity of lower house bolt hole 2c is identical with upper shell bolt hole 1c and the position is corresponding, the external diameter of the annular boss 1b of upper shell and lower house major diameter groove 2b clearance fit; Supporting web plate 3 is plectanes that a surface has intensive through hole, percentage of open area is not less than 80%, support the internal diameter of the external diameter of web plate 3 less than lower house major diameter groove 2b, greater than the internal diameter of lower house minor diameter groove 2d and greater than the internal diameter of upper shell groove 1d, support the port that web plate 3 is sealed on lower house minor diameter groove 2d, the end face of upper shell annular boss 1b will support web plate 3 and compress, and coupling bolt is connected to integral body with upper shell 1 and lower house 2.
Using method of the present utility model is: plane filter material that at first will be to be tested for example filter paper paving is supporting web plate 3 on the surface of upper shell 1, then anchor clamps are assembled, plane filter material to be tested is between the minor diameter groove 2d of upper shell groove 1d and lower house stepped recesses, the center of upper shell 1 connects threaded hole 1e and is communicated with the upstream of testing table by pipeline, the center of lower house 2 connects threaded hole 2e and is communicated with the downstream of testing table by pipeline, the starting characteristics test platform can carry out the filtration efficiency test of plane filter material.
