In order to make more clearly explanation and illustration, reality introduced below to the technical solution of the utility model and implementation
Several preferred specific embodiments of existing technical solutions of the utility model.Obviously, specific embodiment discussed below is only this
A part of the embodiment of utility model, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's every other embodiment obtained without making creative work belongs to the utility model protection
Range.
Specific embodiment 1.
As shown in Figure 1, provided by the utility model be placed in purification tank washes away buoyancy media filtration device certainly, including
Filter cylinder 210, filter cylinder 210 can be assembled by the plate of metal or organic material, and lower end is open, which is put into purification
After in slot, the sewage in purification tank is entered from the lower end open-mouth of filter cylinder 210 carries out purified treatment in filter cylinder 210.
As shown in Fig. 2, upper filter plate 220 and lower filter plate 230 are fixed at interval in the upper and lower in the inner cavity of filter cylinder 210, upper filter plate
220 and the side wall of lower filter plate 230 and filter cylinder 210 be encircled into a space, be filled with light foam filtrate 240 in the space.
Upper filter plate 220 and lower filter plate 230 are made of nylon or polyurethane material.
The material of light foam filtrate 240 be light foam sphere, radius of sphericity be 2~10mm, density be 0.8~
0.9g/cm3.The loading of light foam filtrate 240 accounts for filter plate 220 and lower filter plate 230 and the side wall of filter cylinder 210 surrounds
At space 40%-70%, such as can be 50%.
The top of the inner cavity of filter cylinder 210 is fixed with an effluent weir pipe 250, and filter cylinder 210 is stretched out in the outer end of effluent weir pipe 250
Side wall.Effluent weir pipe 250 can use tubular structure, and for example, by using round tube, the middle part upper end truncation of effluent weir pipe 250 goes out one
A opening will enter in effluent weir pipe 250, and pass through effluent weir pipe 250 when the water level of filter cylinder 210 is higher than this opening
Output.
The side wall upper part of filter cylinder 210 is equipped with overflow recoil hole 260, and overflow recoil hole 260 is located at the top of upper filter plate 220,
Overflow recoil hole 260 can be set to multiple, be separately positioned on two opposite side walls of filter cylinder 210, and be arranged symmetrically.
The course of work of the utility model is as follows:
It is placed on provided by the utility model in purification tank from washing away buoyancy media filtration device, is installed by fixed frame solid
It is fixed, enable from the extension end of the effluent weir pipe 250 for washing away buoyancy media filtration device with purification tank water outlet is closed is connected.
Sewage in purification tank enters in filter cylinder 210 from the lower end open-mouth of filter cylinder 210, then passes through lower filter plate 230
Into purify cavity, in purify cavity, light foam filtrate 240 is deposited under filter plate 220 under the action of water flow buoyancy
Side, is filtered sewage, after through upper filter plate 220 enter clear water chamber；
When the clear water water level in clear water chamber rises to concordant with the opening on effluent weir pipe 250, flowed through effluent weir pipe 250
Purification tank out, for users to use.
When light foam filtrate 240 has intercepted excessive wadding body and increased filtration resistance, water level will therefore in purification tank
Rise, and be flowed into above upper filter plate in filter cylinder 210 by overflow recoil hole 260, from above planting to light foam filtrate
240 are cleaned, and lower filter plate 230 plays the role of obstruction, prevent light foam filtrate 240 from flowing out filter cylinder 210.
Specific embodiment 2.
In order to improve performance, as shown in Figure 2 and Figure 3, overflow is provided on overflow recoil hole 260 in the present embodiment and is recoiled
Pipe 270, overflow recoil tube 270 are arranged in filter cylinder 210, and one end of overflow recoil tube 270 is connected on overflow recoil hole 260.
In addition, overflow recoil tube 270 can use rectangular bend pipe, upper end is connected on overflow recoil hole 260, lower end
Perpendicular to upper filter plate 220, and the lower end of overflow recoil tube 270 is located at the top of upper filter plate 220.
Recoil water flow can be led to by the middle part of upper filter plate using overflow recoil tube 270, to improve the effect of recoil.And
And by more overflow recoil tubes 270, light foam filtrate 240 can also be made uniformly to be recoiled.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn that the enlightenments in the utility model
Under the structure change made, it is all that there is same or similar technical solution with the utility model, each fall within the utility model
