Abstract
The utility model relates to a diaphragm assembly of a hydraulic operated diaphragm pump, which comprises a diaphragm, clipping film plates, a liquid suction pipe and connecting bolts, wherein the diaphragm is formed by overlapping an inner membrane and an outer membrane, and the clipping film plates are divided into an inner clipping diaphragm plate and an outer clipping diaphragm plate; the diaphragm is prefabricated to present in a spherical cap shape, and the cross section of the outer edge of the diaphragm presents in a rectangle; the inner membrane and the outer membrane are processed into a whole body at the center and are bonded with an iron core; the clipping diaphragm plate is a circular ring with a rectangular cross section, an annular groove fit with the outer end of the diaphragm is processed on the clipping diaphragm plate, the clipping diaphragm plate clips the outer end of the diaphragm by the annular groove, a plurality of cylindrical connecting holes are processed onthe outer edge of the clipping diaphragm plate, and the connecting holes are provided with bolts; and the bottom of the clipping diaphragm plate is processed into a plane which is drilled with a radial hole, screw threads are processed on the lower end of the radial hole, and the liquid suction pipe is arranged in the radial hole. The utility model has the characteristics of reasonable force supporting during work, small stress, long service life of the diaphragm, slurry mixing avoidance, long service life of a slurry pump, simple structure, convenient replacement of the diaphragm assembly andthe like.
Description
Technical field
The utility model relates to a kind of mining machinery, particularly a kind of diaphragm pump barrier film assembly that surges on the slurry delivery line.
Background technique
The diaphragm pump barrier film assembly that surges is the slurry transfer pump--the critical component on the diaphragm pump that surges, it mainly acts on is that moving element with slurry body and thick fluid pump is kept apart, thereby has avoided the wearing and tearing of relevant parts, the working life of having improved pump greatly.The barrier film assembly of the existing diaphragm pump that surges is the dark butterfly of individual layer, and it mainly is made up of the displacement detector of barrier film that plays buffer action and the commutation of control diaphragm movement.Its shortcoming is: 1, because barrier film is dark butterfly, and stress is bad during motion, cause barrier film short working life, influence is produced; 2, barrier film is an individual layer, in case break, must cause mixing slurry, and this has not only influenced the working life of whole thick fluid pump, has also caused the waste of the energy and the pollution of environment; 3, because the existence of displacement detector causes the replacing of barrier film assembly very inconvenient.
Summary of the invention
The purpose of this utility model provides a kind of diaphragm pump barrier film assembly that surges, and stressed reasonable when this surges the work of diaphragm pump barrier film assembly, stress is little, the barrier film long service life; Can avoid mixing slurry, the life-span of thick fluid pump is long; Simple in structure, the replacing of barrier film assembly is convenient.
The technical solution of the utility model is: a kind of diaphragm pump barrier film assembly that surges, comprise barrier film, collapser, liquid guiding tube and connecting bolt, and wherein, barrier film forms by interior diaphragm and outer membrane are folded mutually, and collapser and outer collapser were two in collapser was divided into.Barrier film is prefabricated into certain shape, is spherical after the expansion, and the transverse section of its outer rim is a rectangle.Interior diaphragm and outer membrane are processed as one in the center, and are bonded together with an iron core.Interior collapser and outer collapser are the annulus of rectangular cross section.Interior collapser and outside process the circular groove that adapts with interior diaphragm and outer membrane outer end on the collapser.Interior collapser and outer collapser utilize this circular groove that interior diaphragm and outer membrane outer end are clamped, interior collapser and outside the outer rim of collapser process the attachment hole of several cylinders shape, these attachment holes are equipped with bolt.Bottom at interior collapser and outer collapser is processed as a plane, is drilled with radial hole on this plane, and the lower end of this radial hole processes screw thread, installation one liquid guiding tube in radial hole.
Compared with prior art, barrier film of the present utility model is domed after launching, and is stressed reasonable during motion, the barrier film long service life; Barrier film is double-deck, has increased abrasion resistance, can avoid mixing the generation of slurry phenomenon; Cancelled displacement detector, made the simple in structure of barrier film assembly, it is convenient to change.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1.
Parts label among the figure is: 1 is interior diaphragm; 2 add lamina membranacea in being; 3 is bolt; 4 for adding lamina membranacea; 5 is outer membrane; 6 is iron core; 7 is liquid guiding tube; 8 is attachment hole.
Embodiment
See Fig. 1 and Fig. 2, the utility model comprises barrier film, collapser, liquid guiding tube 7 and bolt 3, and wherein, barrier film forms by interior diaphragm 1 and outer membrane 5 are folded mutually, and collapser 2 and outer collapser were 4 two in collapser was divided into.Barrier film is prefabricated into certain shape, is spherical after the expansion, and the transverse section of its outer rim is a rectangle.Interior diaphragm 1 and outer membrane 5 are processed as one in the center, and are bonded together with an iron core 6.Interior collapser 2 and outer collapser 4 are the annulus of rectangular cross section.Interior collapser 2 and outside 4 process the circular groove that adapts with interior diaphragm 1 and outer membrane 5 outer ends on the collapser.Interior collapser 2 and outer collapser 4 utilize this circular groove that interior diaphragm 1 and outer membrane 5 outer ends are clamped, interior collapser 2 and outside the outer rim of collapser 4 process the attachment hole 8 of several cylinders shape, these attachment holes 8 are equipped with bolt 3.Bottom at interior collapser 2 and outer collapser 4 is processed as a plane, is drilled with radial hole on this plane, and the lower end of this radial hole processes screw thread, installation one liquid guiding tube 7 in radial hole.
