Description

A kind of full-automatic back washing sandrock filter
Technical field
This utility model relates to agricultural filter plant field, particularly relates to a kind of full-automatic back washing sandstone Filter.
Background technology
Sandrock filter is also known as quartz filter, sand filter, and it is by particle diameter quartz sands such as homogenizing Form casting bed and carry out the filter of three-dimensional in-depth filtration as filtration supports, be usually used in single filter.Its Mainly use sandstone as media filtration.
The one that prior art discloses Application No. 201220567011.4 washes sandrock filter, by sky Chamber cylinder tank body, the main sewer being arranged on outside tank, water inlet manifold, be divided into two Room by tank inner chamber Vertical baffle, be laid in tank the horizontal net eye plate of bottom for mainly comprising, main sewer, water inlet House steward is connected with the tank body upper wall at place, each room by pipeline respectively, and pipeline is respectively equiped with butterfly valve, and two Above room, on tank skin, each connection is equiped with water pressure gauge, air bleeding valve, on the tank skin of middle part, has manhole. Dividing plate periphery is connected with inner tank wall and horizontal net eye plate, is respectively inserted with tower cap in the mesh of horizontal net eye plate, Above horizontal net eye plate to tower cap, mating formation and have quartz sand layer, the connection of bottom, tank body one end is equiped with out Water pipe.But backwash is not thorough, can affect being carried out continuously of drip irrigation, and the dirt deposited is difficult to clearly Remove.
Utility model content
For the problems referred to above, this utility model provides a kind of full-automatic back washing sandrock filter, solves Backwash of having determined is thorough, can affect being carried out continuously of drip irrigation, and the asking of the dirt deposited not easy-clear Topic.
For solving above-mentioned technical problem, this utility model be the technical scheme is that a kind of Full-automatic reverse Rinsing sandrock filter, its structure includes housing, sand loading mouth, stock solution import, filtrate outlet and row Dirty mouth, described housing is connected to described sand loading mouth, and described housing is connected with switch air valve by pipeline, Described switch air valve is connected by pipeline and first air inlet and exhaust valve table, and described surface of shell connects pressure Watch and open bolt soon, described housing is provided with sealing gasket, and described lower housing portion is connected to exhaust-valve, described Housing back is connected to backwash import, backwash outlets and is just washing import.
Further, it is respectively equipped with 2 about described switch air valve, is connected by pipeline.
Further, described housing is connected to bottom bracket.
Further, described housing bottom is connected by pipeline and second air inlet and exhaust valve table.
Further, described backwash import, described backwash outlets and described just washing import and all pass through pipeline Connect.
From the above-mentioned description to this utility model structure, compared to the prior art, this utility model Have the advantage that
This utility model product has automatic back-flushing function, can realize uninterrupted water supply, and tank bottoms Leave sewage draining exit, at any time the tank bottoms dirt that may deposit is removed from bottom.
Accompanying drawing explanation
The accompanying drawing of the part constituting the application is used for providing being further appreciated by of the present utility model, this The schematic description and description of utility model is used for explaining this utility model, is not intended that this reality With novel improper restriction.In the accompanying drawings:
Fig. 1 is the structural representation of this utility model a kind of full-automatic back washing sandrock filter;
Fig. 2 is the backwash structural representation of this utility model a kind of full-automatic back washing sandrock filter;
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with Drawings and Examples, are further elaborated to this utility model.Should be appreciated that this place is retouched The specific embodiment stated, only in order to explain this utility model, is not used to limit this utility model.
Embodiment 1
With reference to Fig. 1 and Fig. 2, a kind of full-automatic back washing sandrock filter, its structure include housing 2, Sand loading mouth 3, stock solution import 9, filtrate outlet 8 and sewage draining exit 4, described housing 2 is connected to described Sand loading mouth 3, described housing 2 is connected with switch air valve 1 by pipeline, and described switch air valve 1 is by pipe Road and first air inlet and exhaust valve table 13 connect, and described housing 2 surface connects Pressure gauge 11 and opens spiral shell soon Bolt 12, described housing 2 is provided with sealing gasket 10, and described housing 2 bottom is connected to exhaust-valve 6, described Housing 2 back is connected to backwash import 15, backwash outlets 14 and is just washing import 16, described switch gas Valve about 1 is respectively equipped with 2, is connected by pipeline, and described housing 2 is connected to bottom bracket 5, It is connected by pipeline and second air inlet and exhaust valve table 7 bottom described housing 2, described backwash import 15, Described backwash outlets 14 and described just washing import 16 and all connected by pipeline.This utility model product has There is automatic back-flushing function, can realize uninterrupted water supply, and tank bottoms leave sewage draining exit, at any time by tank The dirt that the end may deposit is removed from bottom.
When the most normally working, the water that need to filter reaches dielectric layer by stock solution import 9, the biggest portion Divide pollutant to be trapped within medium upper surface, tiny dirt and other Organic substances floated to be trapped within Inside dielectric layer, to ensure the interference of the most contaminated thing of production system, the work that energy is good.After operation, When impurities in water and various float reach a certain amount of time, this filtration system can be controlled by pressure reduction Device detects inlet outlet pressure differential in real time, and when pressure reduction reaches setting value, automatically controlled PLC can give and control system Threeway hydraulic control valve in system sends signal, and threeway hydraulic control valve can automatically control it by water route The three-way valve of corresponding filter element, allows it close intake channel and opens sewage draining exit 4 simultaneously, at this moment due to Drain outlet pressure is less, and the water of other filter elements can be filtered by by this under the pressure effect of water The entrance filtrate outlet 8 of unit, and the dielectric layer of this filter element of continuous erosion, thus reach to clean The effect of medium, the sewage after flushing is entered by the sewage draining exit 4 of this filter element under the effect of hydraulic pressure Blow-off line, completes a blowdown process.
The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality Type, all any amendment, equivalent and improvement made within spirit of the present utility model and principle Deng, within should be included in protection domain of the present utility model.
