Abstract
The utility model is related to a kind of pump pressure back flush type filters, cyclone above including tank body and in the middle part of tank body, the cyclone has water inlet, slag notch and water outlet, sewage is after water inlet entrance, it is acted on through cyclone, big solid residue is discharged from slag notch, and flow enters from water outlet in tank body to be discharged after filtering.By the way that cobble bed course is arranged below filter layer, it ensure that filter effect, prevent the loss of filtering material, and it is not sealed above filter layer, filtering material can be made fully to expand when backwash, improve the effect of backwash, the sparge pipe group being arranged below filter layer can be in backwash quickly by filtering material rapid expanding in tank body, the time for reducing backwash, improve efficiency.
Description
Technical field
The utility model is related to filter device field, specifically a kind of pump pressure back flush type filter.
Background technology
Back flush type filter is widely used at present, and with filtering accuracy height, filter area is big, both keeps
High flow, and there is the low pressure loss；Easy to operate, cleaning thoroughly, need not install bypass to dismantle blowdown, Wu Xuren
Work carries out cleaning filter core；The advantages of being not required to shut down, is truly realized online blowdown.Prior art CN107497157 A are disclosed
A kind of backwash filter for drip irrigation system realizes that positive filtering, reverse side are rinsed by the structure of filtering net cylinder, existing
Have and mostly use such structure in technology and be filtered, but have the disadvantage that, since the filter material in filtering net cylinder compresses
To ensure filter effect, the expansion of filter material is can not achieve in backwash, flushing is not thorough, and effect is filtered after long-time use
Fruit can substantially reduce, and wash tub pipe is only arranged in flushing process, to reach to mix filter material and wash away in water
Effect, washing time is long, affects service efficiency.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of pump pressure back flush type filters, to solve existing skill
Defect present in art.
The technical solution that the utility model solves above-mentioned technical problem is as follows：
A kind of pump pressure back flush type filter, including tank body and the cyclone positioned at tank body middle part top, the cyclone
With water inlet, slag notch and water outlet, sewage acts on after water inlet entrance through cyclone, and big solid residue is from slagging tap
Mouth discharge, flow enter from water outlet in tank body, are equipped with filter layer in the middle part of tank body, filter layer is located on cobble bed course, flow
It is discharged after filtering by the discharge outlet of tank base；Sparge pipe group, water distribution are equipped between the filter layer and cobble bed course
It is equipped with rotational flow flushing device above pipe group, for being backwashed；
Further, the side of the tank body is provided with visor window and manhole pedestal, be respectively used to observation inner case and
Filter is repaired；
Further, the rotational flow flushing device includes rinsing main pipe and rinsing branch pipe, and spray is provided on the flushing branch pipe
Mouth, the main pipe of rinsing pass through the bend pipe water supply across tank body；The bend pipe is supplied water by external pump, the flushing branch
Pipe is arranged radially.
The utility model has the beneficial effects that：By the way that cobble bed course is arranged below filter layer, it ensure that filter effect, prevent
The loss of filtering material is stopped, and has not been sealed above filter layer, when backwash can be such that filtering material fully expands, and improve
The effect of backwash, the sparge pipe group being arranged below filter layer can be quickly quick by filtering material in tank body in backwash
Expansion, reduces the time of backwash, improves efficiency.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model rotational flow flushing device side view；
Fig. 3 is the utility model rotational flow flushing device vertical view；
Specific implementation mode
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining this practicality
It is novel, it is not intended to limit the scope of the utility model.
As shown in Figs. 1-3, a kind of pump pressure back flush type filter, including tank body and the cyclone positioned at tank body middle part top
1, there is the cyclone 1 water inlet 3, slag notch 4 and water outlet 2, sewage to be acted on through cyclone 1 after the entrance of water inlet 3,
Big solid residue is discharged from slag notch 4, and flow enters from water outlet 2 in tank body, and filter layer 5 is equipped in the middle part of tank body, filters
Layer 5 is located on cobble bed course, and flow is discharged by the discharge outlet of tank base 8 after filtering；The filter layer 5 and cobble bed course
Between be equipped with sparge pipe group 7, rotational flow flushing device 6 is equipped with above sparge pipe group, for being backwashed；
Further, the side of the tank body is provided with visor window 9 and manhole pedestal 10, is respectively used to observation inner case
It is repaired with to filter；
Further, the rotational flow flushing device 6 includes rinsing main pipe 61 and rinsing branch pipe 62, is set on the flushing branch pipe 62
It is equipped with nozzle 63, the main pipe 61 of rinsing passes through the bend pipe water supply across tank body；The bend pipe is supplied water by external pump,
The flushing branch pipe 62 is arranged radially.
Operation principle：When filtering, flow enters from water inlet, is acted on through cyclone, solid is discharged by slag-drip opening, flow
Enter filter from water outlet to be filtered, and be discharged by the discharge outlet of bottom, when being backwashed, first passes through sparge pipe
Group water filling so that filtering material fully expands, and flow is then pumped into rotational flow flushing device by water pump, nozzle rinses upwards, makes
The flow containing impurity screening such as oil, slag is obtained to be discharged through slag-drip opening by water outlet.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
