Description
Technical field
The present invention relates to a kind of diaphragm pump, especially relate to a kind of diaphragm pump structure that is applicable to carry slurry.
Background technique
Because the abrasion of slurry is stronger, if material contacts with plunger, filler in course of conveying, will cause the wearing and tearing of plunger, filler, working life is shorter, therefore generally adopt diaphragm pump to carry.The flowing hole of at present domestic and international diaphragm pump chamber barrier film confinement plate is the aperture of equal diameter, because barrier film confinement plate chamber is middle high, peripheral low, thereby the flowing hole in the middle of confinement plate is shorter, on-way resistance during overcurrent is little, and fluid mainly concentrates on the middle part of barrier film confinement plate to be passed through; The flowing hole of periphery is longer, and on-way resistance during overcurrent is relatively large, and the flow that fluid passes through from periphery is few; When slurry passes through peripheral aperture, easily generation precipitation obstruction, particularly cavity bottom more easily form the precipitation of granule materials and gather.Current chamber flowing hole is generally the level vertical with the barrier film confinement plate, parallel aperture, due to easily depositing particle, in course of conveying, mainly take and suspending movement, jump movement and rolling as main, and horizontal apertures is unfavorable for motion and the conveying of granule materials; Particularly the aperture of barrier film confinement plate periphery, extended the time of passing through because the degree of depth increases, and on-way resistance increases, and its flow velocity is slowed down, and moving particle can produce deposition because power reduces.Above reason has caused the common diaphragm pump often to occur that when carrying the easily depositing particle medium precipitation, obstruction, bottom the phenomenon such as gather, and causes barrier film local deformation and stress to increase, and causes membrane ruptures, and working life is very short.
So barrier film and one-way valve seat need regularly to change, when particularly high granularity is applied, barrier film and one-way valve seat replacement cycle are short, and maintainability is poor, uneconomical; Affect produced on-site simultaneously.
Summary of the invention
Purpose of the present invention is exactly a kind of operating conditions while improving the application of barrier film slurry is provided in order to overcome the defect that above-mentioned prior art exists, extends barrier film and the diaphragm pump structure that is applicable to carry slurry in one-way valve seat life-span.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of diaphragm pump structure that is applicable to carry slurry, comprise diaphragm pump head, barrier film and one-way valve, described barrier film is located on diaphragm pump head, also comprises medium runner and deposit cavity, described deposit cavity is connected with diaphragm pump head, and described one-way valve is connected with deposit cavity by medium runner;
Open one-way valve operation diaphragm pump, slurry medium enters deposit cavity by medium runner, and slurry medium enters diaphragm pump head in deposit cavity after layering.
Described deposit cavity vertically arranges.
When the media particle density in slurry is greater than medium solution density, deposit cavity arranges vertically downward.
When the media particle density in slurry is less than medium solution density, deposit cavity arranges vertically upward.
Described deposit cavity end is provided with deposited particles drainage plug screw.
Described deposit cavity comprises the first deposit cavity and the second deposit cavity, and described the first deposit cavity is connected with diaphragm pump head, and described the second deposit cavity is connected with one-way valve by medium runner.
Described one-way valve comprises one-way valve seat, and this one-way valve seat is the valve seat that is embedded with Tungsten carbite.
Described diaphragm pump head top is provided with outlet valve.
Compared with prior art, barrier film and not high shortcoming of one-way valve seat life-span while the invention solves the application of diaphragm pump slurry have the following advantages:
1) the present invention, by deposit cavity is set, reduces near the media particle degree of barrier film, improves the operating mode of barrier film operation, thereby reaches the purpose that extends membrane life;
2) the high Tungsten carbite of the embedded hardness of one-way valve seat of the present invention, improve one-way valve seat hardness, strengthen wear-corrosion resistance, thereby improve the one-way valve seat life-span.
