Description
Technical field
The utility model relates to a kind of air pump, is specifically related to one and carries sand device air pump assembly.
Background technique
Continuous Flow sand filter is a kind of continuous print filter, and it does not need to shut down rinses or backwash.Water inlet adverse current is upwards by casting bed, and filter sand moves down simultaneously.While filtration, the filter sand of pollution cleans up in sand-washing device, and suspended matter is got rid of via rinse water.
Existing part is carried sand device air pump parts and is formed by stainless steel welded, its heavier-weight, make low precision, rough surface, and processing dimension is uneven; Also have part to carry sand device air pump parts to be made by nylon material lathe, make trouble, do not meet usage requirement.Major part carries sand device air pump parts does not have filter screen, and sand grains can enter air chamber, affects air pump using effect, and maintenance dismounting inconvenience, corrosion-resistant.
Summary of the invention
Goal of the invention: the purpose of this utility model is to overcome deficiency of the prior art, provide a kind of one-body molded, easy installation and removal, uniform air distribution, can effectively prevent sand grains from entering, and corrosion resistantly novelly carries sand device air pump.
Technological scheme: in order to solve the problems of the technologies described above, one described in the utility model is novel carries sand device air pump, it comprises upper connector and lower link, their close-fittings connect, grid filter core is provided with in described upper connector and lower link, described upper connector, lower link and grid filter core composition air pump body, installation passage is provided with in the middle part of described upper connector and lower link, the upper connector upper wall side other at the installation passage of described upper connector is provided with inlet hole, upper filter installation step is provided with in the installation passage of described upper connector, lower filter installation step is provided with in the installation passage of described lower link, the outer side surface of described upper filter installation step and lower filter installation step is established on the same line, described grid filter core is located at the outer side surface place of described upper filter installation step and lower filter installation step.
Described upper connector and lower link are all ABS or nylon or reinforced plastic link.
Described grid filter core is the stainless steel filter core (filter screen) in 0.4-1.0mm gap.
Described air pump body is located at the through hole on ABS or nylon or reinforced plastic straight tube.
The installation channel upper of described lower link is taper type.
The working principle of Continuous Flow sand filter is: former water enters filter by intake pipe and the distribution of eight pawl water-dispensing devices, former water is risen by the mobile casting bed constantly declined, filter liquor is discharged via the effluent pipe mouth above overflow weir and filter, dirty sand rises in the sand-washing device of filter top by the air lift of filter bottom, through the reverse cleaning of upper strata filtrate when then moving down from sand-washing device bellows, clean sand after cleaning falls back on the surface on filter casting bed, again participate in filtering, the washed-out sand water being mingled with suspended solid is discharged through useless outlet.
Air lift is fixed on straight tube, and its suction port is positioned at the bottom of filter.The Liquid level that filter sand is promoted in filter top sand-washing device by air sand extraction pump is indoor, and the filter sand amount pumped into depends on the compressed air require in air lift.Along with the increase of air-flow will take in more filter sands, vice versa.Pressurized air is through air input connector, and special input support tube input flexible pipe and air sparging room enter pump.The mixture of air, sand and water up flows through outlet of air pump and enters Liquid level room.Sand falls back to bottom sand-washing device, is cleaned through filtrate from bottom to top.The impurity that density is less than filter sand by with washed-out sand water from waste water drain get rid of splash-back and splash guard prevent sand from sand-washing device splash and go out, the mixture of sand and water up flows through air pump sand and falls back to bottom sand-washing device, clean through filtrate from bottom to top.
Beneficial effect: the utility model compared with prior art, its remarkable advantage is: the utility model overall structure is simple, described upper connector and lower link by ABS or nylon or reinforced plastic integrated die-casting shaping, oeverall quality is lighter, and size uniform, adopt upper filter installation step and lower filter installation step, filter core is made to install firmly, adopt the grid filter core in 0.4-1.0mm gap, can effectively prevent sand grains from entering air chamber, do not affect the progress of work, and the effect of uniform air distribution can be played, the installation channel upper of described lower link is taper type, larger filtration knockout space is provided, this product maintenance convenient disassembly, corrosion resistance and good, realistic usage requirement.
