Description

A hierarchical filter equipment for different velocity of flow pipelines

Technical Field

The utility model relates to a hierarchical filter equipment for different velocity of flow pipelines belongs to the clean technical field of flowing water.

Background

The pipeline is very common in our daily life, and the pipeline is all needed in the transport of drinking water, drainage irrigation, laboratory glassware water delivery and drainage, domestic sewage discharge etc. and the water piping that needs to use in hydroelectric power plant is more, in various water conservation water purification links, preliminary filtration is very important, and light impurity, greasy dirt, insoluble impurity are all the part of aquatic impurity.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a can be according to the water velocity size filtration mode of adjusting, filtration light impurity, greasy dirt are preliminary graded to the preliminary stage filtration, with solid insoluble impurity, filter equipment in removable filter screen and activated carbon's the pipeline.

The utility model discloses a following technical scheme realizes:

the utility model provides a hierarchical filter equipment for different velocity of flow pipelines, hierarchical filter equipment includes upper and lower two parallel arrangement's pipeline, and two mutual intercommunications of pipeline are a mouthful font, and the end of intaking of upper tube says and trunk line intercommunication, and the play water end and the trunk line intercommunication of lower tube say, and the end of intaking of upper tube says is provided with preceding valve, and the play water end of lower tube says and is provided with the back valve, has set gradually active carbon and filter screen one along the rivers direction in the upper tube way between preceding valve and the back valve, is provided with filter screen two in the lower tube way between preceding valve and the back valve.

Preferably, a second filter screen and a manual valve are sequentially arranged in a lower pipeline between the front valve and the rear valve along the water flow direction.

The front valve and the rear valve in the pipeline are both in an open state at ordinary times, and the manual valve in the lower pipeline is opened and closed according to the size of water flow.

Preferably, in order to conveniently replace the activated carbon and the first filter screen and clean impurities, an access door is arranged on the pipe wall of the upper pipeline for installing the activated carbon and the first filter screen.

Preferably, in order to conveniently replace the second filter screen and clean impurities, an access door is arranged on the pipe wall of the second lower pipeline installation filter screen.

The method comprises the following steps:

when the water flow is large:

and opening a manual valve of the lower pipeline, opening a front valve and a rear valve, enabling water flow to pass through the upper pipeline and the lower pipeline, depositing heavy insoluble solid impurities at a second filter screen along the water flow, and enabling oil stains and suspended matters with light weight to pass through the activated carbon of the upper pipeline and the first filter screen to achieve the filtering purpose.

When preparing to change and wash filter screen and active carbon, close preceding valve earlier, utilize gravity to discharge water, treat the rivers in the upper tube way after the lower pipeline, close the back valve, later open the access door on upper and lower pipeline, change impurity, filter screen and active carbon and clear up.

When the water flow is small:

and closing a manual valve in the lower pipeline, opening the front valve and the rear valve, depositing solid impurities at a second lower pipeline filter screen along water flow under the condition of low flow rate, and allowing light oil stains and suspended matters to flow to the first filter screen and the activated carbon through the water flow to achieve the purpose of filtering.

The technical effects of the utility model reside in that:

the utility model discloses utilize gravity tentatively part two kinds of impurity and filter respectively to consider water velocity's variation in size, the manual valve who has installed the flow direction additional for abundant filtration and has adjusted handles this problem.

The utility model discloses can carry out preliminary settlement and partial filtration in the pipeline in sewage treatment, can reduce the harm that the moisture brought to the hydraulic turbine in the drain of hydroelectric generation pipe, can the multistage set up this device, carry out a lot of filtration.

Drawings

Fig. 1 shows a specific structure of the present invention.

Detailed Description

As shown in figure 1, a hierarchical filter equipment for different velocity of flow pipelines, a serial communication port, hierarchical filter equipment includes upper and lower two parallel arrangement's pipeline, two pipelines communicate each other and are the mouth font, the end of intaking of upper pipeline and trunk line intercommunication, the play water end and the trunk line intercommunication of lower pipeline, the end of intaking of upper pipeline is provided with front valve 1, the play water end of lower pipeline is provided with back valve 3, activated carbon 4 and filter screen 5 have set gradually along the rivers direction in the upper pipeline between front valve and the back valve, filter screen two 6 and manual valve 2 have set gradually along the rivers direction in the lower pipeline between front valve and the back valve.

Preceding, back valve control trunk line rivers, the top tube has filter screen one and the active carbon of main filtration greasy dirt and suspended solid, can dismantle filter screen one and active carbon for convenient taking out and installation, set up access door 7 that can open on the pipe wall, access door and tube sealing connection, the lower pipeline has the filter screen two of main filtration solid deposition impurity, for convenient taking out and installation filter screen two, also set up the access door 7 that can open on the lower pipeline pipe wall, still be provided with the manual valve 2 of control flow direction under different rivers velocity of flow in the lower pipeline.

Defining normal flow of water flow in the main water flow pipeline, and defining the direction of the water flow in the pressure pipeline as from right to left;

when the water flow is large:

and opening a lower pipeline manual valve 2, opening a front valve 1 and a rear valve 3, enabling water flow to pass through an upper pipeline and a lower pipeline, depositing heavy insoluble solid impurities at a second filter screen along the water flow, and enabling light oil stains and suspended matters to pass through an upper pipeline activated carbon and a first filter screen to achieve the filtering purpose.

When the water flow is small:

and (3) closing the manual valve (2) in the lower pipeline, opening the front valve and the rear valve, and depositing solid impurities at a second lower pipeline filter screen along with water flow under the condition of low flow rate, wherein light oil stains and suspended matters flow to the first lower pipeline filter screen and the activated carbon through the water flow to achieve the purpose of filtering.
