Description

A kind of combined centrifugal filter that removes sand

One, technical field

The utility model relates to water treatment facilities, relates in particular to a kind of combined centrifugal filter that removes sand.

Two, background technology

Water will be handled through the silt impurity of removing in the water usually, could use in producing, living.Centrifugal sand cleaning machine is a kind ofly to be used for removing water greater than the most effective treatment facility of water than heavy substance, because that it has is simple in structure, cost is low, the advantage of easy to maintenance and no energy consumption, and extensive use in water treatment facilities.Conventional centrifugal sand cleaning machine mostly press water flow customization specification, single centrifugal sand cleaning machine filtration, its defective is: bulky, be not easy to other fine filter supporting, the installation and maintenance difficulty.

Three, summary of the invention

It is little that the purpose of this utility model provides a kind of occupation of land space, be convenient to other fine filter supporting, convenient for installation and maintenance, the wide combined centrifugal of the scope of application filter that removes sand.

The utility model combined centrifugal filter that removes sand, be characterized in: it is connected to form by several centrifugal filter elements that remove sand, the single centrifugal filter element that removes sand comprises: water inlet manifold, support, a centrifugal sand cleaning machine, deposit husky jar and outfall sewer, the two ends of water inlet manifold, the two ends of outfall sewer, deposit husky jar two ends the connection groove all is set, described connection groove and groove type pipe connector are suitable, water inlet manifold, outfall sewer, depositing a husky jar three is arranged in parallel, described centrifugal sand cleaning machine is arranged on the arm between water inlet manifold and the outfall sewer, described depositing on husky jar is provided with sand inlet, described sand inlet is connected with the sand output line of described centrifugal sand cleaning machine, water inlet manifold between two unit, outfall sewer with deposit husky jar and be connected water inlet manifold with the groove type pipe connector by the described groove that is connected, outfall sewer and deposit a husky jar of terminal groove blind plate is set.

In the such scheme, in the described centrifugal sand cleaning machine guide ring can be set, described guide ring is the spiral plate of 3/4 circle, the spiral plate inboard links to each other with exit branch, the spiral plate outside links to each other with cylindrical shell, and the initiating terminal of guide ring is over against the water inlet arm, and its height is identical with the diameter of water inlet arm.The advantage of guide ring is: water is passing through the water inlet arm, tangentially enter behind the cylindrical shell because the spirally-guided effect of guide ring, water produces rotation downwards, the backspin current are walked around into water, water inlet are not produced extruding, owing to there is not the interference of water inlet, the water flow velocity of rotation improves greatly, and prolong at cylindrical shell and cylindrical shell awl holdup time, impurity such as water and sand are fully separated.

The utility model workflow is: after former water enters from water inlet manifold, be assigned to each centrifugal sand cleaning machine by arm, behind the prefiltration of centrifugal sand cleaning machine, by the fine filter secondary filter, the water purification after the filtration is discharged by outfall sewer.The isolated sand fallout of centrifugal sand cleaning machine regularly or is regularly opened mud valve depositing in husky jar, and silt is discharged.The air valve of installing on the outfall sewer is used for the air of automatic discharge filter, in case the generation of vapour lock.The water-in and water-out house steward respectively is equipped with a Pressure gauge, and in order to judging the pollution level of fine filter, when two manometric pressure reduction during greater than certain numerical value, the butterfly valve that can cut out the fine filter two ends is so that clean filter core.The advantage of this connection pattern is a compact conformation, it is little to take up an area of the space, can be according to the size of discharge, the serial or parallel connection filter unit enlarges flow, to satisfy client's needs easily, the husky jar of depositing that while is in parallel is collected the interior silt of each sand cleaning machine, can unify discharging easily, supporting with magnetic valve, backwash valve and controller, complete machine can the row's of realization sand, automatically the carrying out of fine filter backwash.
