Abstract
A water impurity filter is composed of a filter body and a filter core, wherein the front input end of the filter body and the rear output end of the filter core are provided with flanges; the lower part of the filter is provided with a sewer valve; the front input end of the filter body is connected with a front flange pipe through a front brake valve; the rear output end of the filter core is connected with a rear flange pipe through a rear brake valve; the front flange pipe and the rear flange pipe are provided with pressure gauges; a back flushing pipe is connected between the front flange pipe and the output end of the filter core, and is provided with an automatic flushing valve. The water impurity filter is arranged in a pipeline with poor water quality needing filtering. The utility model has the advantages of environmental protection, energy saving, simple structure, reliable control, and convenient operation and popularization.
Description
Technical field:
The utility model relates to a kind of water contaminant filter, is mainly used in the place that water quality inferiority in the colliery, foreign material need water filtration more.
Background technology:
The colliery is in the coal mining process, for the coal dust that reduces silo shearer and boring head is realized safety in production, must use dust prevention sprinkler to spray and reduce coal dust, because the dustproof fog-spray nozzle bore Xiao Yi of high pressure stops up, so must use pure relatively water avoids normally being used by the impurity congestion affects in the water, and after supply channel uses for many years under the general coal mine, the more water quality variation that makes of iron rust and impurity does not reach instructions for use, this just need install the water contaminant filter on water supply line, but does not have a kind of volume little at present, simple in structure and service-strong filter.
Summary of the invention:
The purpose of this utility model provides a kind of water contaminant filter, and is simple in structure, adopts and manually controls the order ground that reaches water filtration, promptly safe and reliable flexible operation again.
The purpose of this utility model realizes as follows: this water contaminant filter, filter is made of filter body and filter core, output is provided with flange behind preceding input of filter body and the filter core, the filter body below is provided with blowoff valve, input connects the forward flange pipe by preceding gate valve before the filter body, output connects the rear flange pipe by the back gate valve behind the filter core, is connected with recoil tube between the output behind forward flange pipe and the filter core, and self-flushing valve is housed on the recoil tube.
On forward flange pipe and the rear flange pipe Pressure gauge is housed.
Gate valve and back gate valve are opened simultaneously before during use, and self-flushing valve and blowoff valve are closed, and water filters by the filter core of filter, the pressure basically identical that front and back two Pressure gauges are shown; When difference appears in front and back two Pressure gauges, close the back gate valve, open self-flushing valve and blowoff valve water backwashing, water impurity is discharged.
The beneficial effects of the utility model are: being installed in water quality inferiority needs in the pipeline of water filtration, this device environmental protection, energy-conservation, simple in structure, control is reliable, be convenient to construction and promote.
Description of drawings:
Accompanying drawing is the structural representation of the utility model water contaminant filter.
Gate valve behind gate valve, 6-snap joint, 7-filter body, 8-filter core, 9-flange, 10-forward flange pipe, 11-rear flange pipe, the 12-before 1-Pressure gauge, 2-self-flushing valve, 3-recoil tube, 4-blowoff valve, the 5-
The specific embodiment:
With reference to accompanying drawing, filter is made of filter body 7 and filter core 8, input and filter core 8 back outputs are provided with flange 9 before the filter body 7, filter body 7 belows are provided with blowoff valve 4, input adopts flange connection to connect forward flange pipe 10 by preceding gate valve 5 before the filter body 7, filter core 8 back outputs adopt flange connection to connect rear flange pipe 11 by back gate valve 12, on forward flange pipe 10 and the rear flange pipe 11 Pressure gauge 1 is housed, be connected with recoil tube 3 by snap joint 6 between forward flange pipe 10 and the filter core 8 back outputs, self-flushing valve 2 is housed on the recoil tube 3.
