Abstract

The utility model discloses a pipeline filter which comprises a main body, a filter screen, a backwashing pipe, a first valve, a second valve, a third valve and a fourth valve. A water inlet, a water outlet and a water discharging opening are arranged on the main body. The filter screen separates the main body into two sections. The water inlet and the water discharging opening are arranged on one side of the filter screen, and the water outlet is arranged on the other side of the filter screen. The first valve is disposed on a pipeline communicated with the water inlet of the main body, and the second valve is disposed on a pipeline communicated with the water outlet of the main body. The third valve is arranged on a pipeline communicated with the water discharging opening of the main body. One end of the backwashing pipe is communicated with a water inlet pipeline of the first valve, and the other end of the backwashing pipe is communicated with a pipeline of the second valve. The fourth valve is arranged on the backwashing pipe. The pipeline filter is directly arranged on the pipeline of a recycling cooling water system, controls the valves, automatically eliminates sundries in the pipelines of a recycling cooling water system, does not need an additional water quality filter, saves investments of a long-distance pipeline, and is simple in structure and low in cost.

Description

A kind of piping filter

Technical field

The utility model relates to a kind of piping filter.

Background technology

Recirculating cooling water system is indispensable crucial enforcement of each industrial department; And present this circulation mostly adopts open cooling tower; Comprise mechanical-draft cooling tower and large-scale cooling stack, its air inlet all is open, because impurity and environmental factor such as foreign material such as sand and dust, industrial dust, leaf, filler fragment, birds and toy cause the obstruction of circulating water pipeline easily in the water; Then influence industrial efficient; Cause energy waste, increase production cost, need to be resolved hurrily.

The utility model content

The utility model technical problem to be solved provides a kind of piping filter that can remove foreign material in the recirculating cooling water system pipeline automatically, thoroughly solves the clogging of pipeline.

In order to solve the problems of the technologies described above, the technical scheme that the utility model provided is: a kind of piping filter comprises main body, filter screen, backwash tube, first valve, second valve, the 3rd valve and the 4th valve; Said main body is provided with water inlet, delivery port and discharge outlet; Said filter screen is divided into two parts with body interior, and water inlet and discharge outlet are positioned at a side of filter screen, and delivery port is positioned at the opposite side of filter screen; Said first valve is arranged on the pipeline that water inlet was communicated with of main body; Said second valve is arranged on the pipeline that delivery port was communicated with of main body; Said the 3rd valve is arranged on the pipeline that discharge outlet was communicated with of main body; One end of said backwash tube is communicated with the inlet pipeline of first valve, and the other end is communicated with the inlet pipeline of second valve; Said the 4th valve is arranged on the backwash tube.

Said filter screen is arranged on the center of main body.

Be respectively equipped with a Pressure gauge on two parts that said main body is separated out by filter screen.

After having adopted technique scheme; The utlity model has following beneficial effect: the utility model is set directly on the pipeline of recirculating cooling water system, through the control to valve, removes the ducted foreign material of recirculating cooling water system automatically; Do not need to establish in addition water filter; Saved the investment of long-distance pipe, simple in structure, cost is low.

Description of drawings

For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation, wherein below according to specific embodiment and combine accompanying drawing

Fig. 1 is the structural representation of the utility model.

Label in the accompanying drawing is:

Main body 1, water inlet 11, delivery port 12, discharge outlet 13, filter screen 2, backwash tube 3, first valve 4, second valve 5, the 3rd valve 6, the 4th valve 7, Pressure gauge 8.

The specific embodiment

(embodiment 1)

See Fig. 1, the piping filter of present embodiment comprises main body 1, filter screen 2, backwash tube 3, first valve 4, second valve 5, the 3rd valve 6, the 4th valve 7 and Pressure gauge 8.

Main body 1 is provided with water inlet 11, delivery port 12 and discharge outlet 13.Filter screen 2 is arranged on the center of main body 1, and main body 1 inside is divided into two parts, and water inlet 11 and discharge outlet 13 are positioned at a side of filter screen 2, and delivery port 12 is positioned at the opposite side of filter screen 2; On the pipeline that the water inlet 11 that said first valve 4 is arranged on main body 1 is communicated with; On the pipeline that the delivery port 12 that said second valve 5 is arranged on main body 1 is communicated with; On the pipeline that the discharge outlet 13 that said the 3rd valve 6 is arranged on main body 1 is communicated with; One end of said backwash tube 3 is communicated with the inlet pipeline of first valve 4, and the other end is communicated with the inlet pipeline of second valve 5; Said the 4th valve 7 is arranged on the backwash tube 3.Be respectively equipped with a Pressure gauge 8 on two parts that main body 1 is separated out by filter screen 2.

Piping filter is arranged on the pipeline of recirculating cooling water system, and when recirculated water was in normal operating condition, first valve 4 and second valve 5 were opened, and the 3rd valve 6 and the 4th valve 7 are closed.

When needs carried out backwash, first valve 4 and second valve 5 were closed, and the 3rd valve 6 and the 4th valve 7 are opened, and all impurity that filter screen 2 is tackled are promptly discharged from the 3rd valve 6.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
