Abstract

The utility model relates to a vortex gravel filter, belonging to the filter class; the utility model is based on the filter, the filter is composed of a housing, a bracket, a blow-off valve, a water inlet pipe, an exhaust valve, a filter plate, and a gravel layer; the housing is the barrel shape, and the blow-off valve is arranged on the bottom face of the housing; the necking circumference of the housing is welded with a vortex cylinder, the cylinder wall of the vortex cylinder is provided with air holes, and the upper port of the vortex cylinder is provided with flanges; the water inlet pipe is welded on the upper part of the housing in tangential direction, the filter plate is an inner filter cup in deep cup shape, and the wall of the inner filter cup is studded with mesh; the upper port of the inner filter cup is provided with flanges, the external circumference on the upper part of the inner filter cup is welded with a flange with the exhaust valve, and the external side of the inner filter cup is provided with the gravel layer; the vortex gravel filter has the functions of first centrifugal separation and secondary filtering, having simple structure, having favorable filtering effect, and having high efficiency; the vortex gravel filter can be continuously or periodically blew-off in operation; the vortex gravel filter has the positive effect of convenient maintenance.

Description

Vortex gravel filter

The utility model belongs to the filter class.

Existing gravel filter is to fix a L shaped water pipe that stretches in the housing in the bottom surface of housing; The filter plate of ring-type is housed in the ring cavity between the standpipe of housing and water inlet pipe, in the ring cavity above the filter plate gravel layer is housed.Water rises to the cavity top of housing through water inlet pipe, and water purification flows out from lower housing portion.The problem of this filter is: the annular filter area is less, and volume is bigger, and resistance is bigger, and efficient is lower; Water inlet only is a disposable filtering through gravel layer and filter plate, impurity is deposited on above the gravel layer and gravel layer, filter plate in the middle of, easily stop up, need often to clean, need stop long journey during cleaning, the maintenance removal of contamination is taken a lot of work bothersome.

Order of the present utility model is: provide a kind of volume little, filter area is big, and resistance is little, and efficient is high, easy to maintenance saving trouble, the eddy flow gravel filter of secondary filter.

Technical measures of the present utility model are: with by housing and support, and blowoff valve, water inlet pipe, air bleeding valve, filter plate, the filter that gravel layer is formed is the basis: housing is barrel-shaped, blowoff valve and housing bottom surface; The top periphery seam of housing has a whirl cylinder; On the wall of whirl cylinder pore is arranged, upper port has ring flange; The tangential seam of water inlet pipe is in the outside on housing top; Filter plate is dark cup-shaped interior filter bowl, is densely covered with mesh on the wall of cup, and upper port has ring flange, and the seam of upper periphery edge has ring flange, on this ring flange air bleeding valve is housed; Be furnished with gravel layer in the interior filter bowl outside.

Filter of the present utility model, water inlet enters housing and produces eddy flow through tangential water inlet pipe, the impurity that quality is bigger in the water precipitates under the effect of centrifugal force and gravity with the bottom emits through blowoff valve, tiny impurity is leached by gravel layer and interior filter bowl, water purification is drawn through interior filter bowl is suitable for reading, and this filter has first-stage centrifugal to separate and the function of cascade filtration; Have simple in structure, good filtration effect, resistance is little, continuous or periodic blowdown, the good effect easy to maintenance of carrying out in service.

Fig. 1 structural representation of the present utility model; Fig. 2 is a vertical view; Fig. 3 is a structural representation of the present utility model.

1 is barrel-shaped housing among the figure, the 8th, and support, blowoff valve 7 is in the bottom of housing 1; Reducing periphery seam on the housing 1 has a whirl cylinder 12, makes the current that tangentially enter narrow chamber in the housing produce eddy flow.On the wall of whirl cylinder 12 pore is arranged, upper port has ring flange.Water inlet pipe 11 tangential seam are on the outer wall on housing 1 top; Make water tangentially enter housing and produce eddy flow, make the impurity that quality is bigger in the water sink to emitting by blowoff valve 7 in the effect lower edge of centrifugal force and gravity inner walls.Filter plate is to adopt dark cup-shaped interior filter bowl 2, is densely covered with mesh on the wall of cup, and upper port has the ring flange that is connected with outlet pipe, and interior filter bowl 2 upper periphery edge seam have the ring flange that is connected with housing 1 upper port, and air bleeding valve 9 is housed on this ring flange.The outside at interior filter bowl 2 is furnished with gravel layer; Gravel layer can be: by interior filter bowl 2 outsides, the loose gravel 4 that fills in the cavity between outer filter bowl 3 meshed, that upper port is connected with the ring flange on interior filter bowl 2 tops and the inside and outside filter bowl that gathers on the wall forms.The gravel layer in interior filter bowl 2 outsides can also be: the gravel layer 4(that pastes knot at interior filter bowl 2 outer walls sees Fig. 3), just will be mixed with the tetrapods that pastes the knot agent and paste knot on the outer wall of interior filter bowl 2.10 is for packing, pour out the seal cover of tetrapods among the figure; For filter bowl 3 in making is better located, but at screw rod 5 of interior filter bowl 2 lower ends outside seam, screw rod 5 sees through the bottom surface of outer filter bowl 3 and strains the location with nut 6.

Claims
