Description

Piping filter

Technical field

The utility model relates to water treatment engineering technology field, especially a kind of piping filter.

Background technique

Filter is indispensable a kind of device on pumped (conveying) medium pipeline, is typically mounted at the input end of pipeline, is led to Normal filter is the filter cylinder for being equipped with strainer, and when flowing through filter cylinder, impurity is blocked pumped (conveying) medium, reaches the mesh of filtering 's.

For example contain the relatively small sundries of particle in sewage, and it should not be intercepted and be fished for equipment such as grid, grid, pipeline mistake Filter can then intercept these lesser sundries, mitigate the load of subsequent treatment process.

For the prior art, filter is difficult to remove in sewage currently on the market relatively small miscellaneous containing particle Object, and take up an area face and very much not can solve practical problem.So how to develop a kind of higher filter pipeline of practicability Device is the direction to be studied of this field staff.

Utility model content

In view of the defect of the above-mentioned prior art, the purpose of this utility model is that: provide in a kind of removal sewage containing The relatively small sundries of grain, and the piping filter that occupied area is small.

The technical solution of the utility model is: a kind of piping filter, including water inlet, filter housing, filtering Device inner casing and water outlet, the filter housing, filter inner casing both ends corresponding position be respectively provided with and communicate with external water pipe Multiple filter hole, the filter inner casing is arranged in water inlet and water outlet, the filter inner casing on the side wall of water outlet Bottom setting drain outlet simultaneously extends to outside filter housing, and blowdown lock is arranged on the drain outlet outside the filter housing Valve.

In above-mentioned piping filter, the filter inner housing inner is provided with the filter screen of tilt angle.

In above-mentioned piping filter, access hole is set on the filter housing.

In above-mentioned piping filter, the water inlet, water outlet and external water pipe are connected by connecting flange.

In above-mentioned piping filter, at least one fixed frame is set on the outer surface of the filter inner casing, at least One fixed frame is contacted with the inner surface of the filter housing, makes the axle center of the filter inner casing and the filter The axle center of shell is overlapped.

In above-mentioned piping filter, outer surface and the mistake of the length of the fixed frame for the filter inner casing The radial distance of the inner surface of filter shell.

In above-mentioned piping filter, the bracket to play a supportive role is arranged in the bottom of the filter housing.

The beneficial effects of the utility model are:

It is dirty by being evenly arranged a certain number of filter hole of go-no-go on side wall of the filter inner casing close to water outlet Water will be intercepted by Shi Shuizhong sundries；Keep filter effect more preferable by the way that filter screen is arranged again in filter inner housing inner；It will The filter screen is obliquely installed, and slows down the impact force of water flow, and making filter screen, the service life is longer；Through after a period of time to pipe After interior accumulation certain amount sundries, after setting blowoff gate valve, openable water outlet blowoff gate valve, which utilizes, manages interior natural stream networks, Dirt is removed, outside discharge filter；By the way that access hole is arranged, observation is facilitated to repair, the normal use of to maintain equipment；It can basis The actual conditions such as bore, volume select vertical or horizontal filter.

Specific embodiment

For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing Unrestricted feature description is as follows:

As shown in Figure 1 to Figure 2, a kind of piping filter, including water inlet 110, filter housing 100, filter inner casing 200 and water outlet 120, filter housing 100, filter inner casing 200 both ends corresponding position be respectively provided with and communicated with external water pipe Water inlet 110 and water outlet 120, multiple filter hole 210 are arranged in filter inner casing 200 on the side wall of water outlet 120, lead to It crosses and is evenly arranged a certain number of filter hole 210 of go-no-go on the side wall of water outlet 120 in filter inner casing 200, it is dirty Water will be intercepted by Shi Shuizhong sundries.

200 bottom of filter inner casing setting drain outlet 300 simultaneously extends to outside filter housing 100, in filter housing Blowoff gate valve 310 is set on the drain outlet 300 outside 100.After setting blowoff gate valve 310, openable water outlet blowdown lock Valve 310, which utilizes, manages interior natural stream networks, removing dirt, outside discharge filter.

Preferably, in the utility model, the filter screen 220 of tilt angle is also provided with inside filter inner casing 200. Keep filter effect more preferable by the way that filter screen 220 is arranged again inside filter inner casing 200, and filter screen 220 is obliquely installed, subtracts The impact force for having delayed water flow, making filter screen 220, the service life is longer.

It is worth noting that, filter screen 220 should be set to after drain outlet 300, be designed in this way can be only achieved it is practical The novel purpose for removing filtering foreign.

Specifically, access hole 130 is arranged on filter housing 100, access hole 130 is set as filtering in the utility model On the upper surface of device shell 100, observation is facilitated to repair, the normal use of to maintain equipment.

It is convenient disassembly, strong specifically, water inlet 110, water outlet 120, which pass through connecting flange with external water pipe, connect 140 Degree height, good seal performance.

In the utility model will at least one fixed frame 230 be set on the outer surface of filter inner casing 200, at least one is solid Determine frame 230 to contact with the inner surface of filter housing 100, makes the axle center of filter inner casing 200 and the axle center of filter housing 100 It is overlapped.

Specifically, the length of fixed frame 230 is the outer surface of filter inner casing 200 and the inner surface of filter housing 100 Radial distance.

Fixed frame 230 is made to support filter inner casing 200 and support filter housing 100 on same central axis Water filter preferably operates.

Preferably, fixed frame 230 can be made of angle steel or band steel, set three for fixed frame 230 in the utility model It is a, so that structure is more stable.

Preferably, the bracket 400 to play a supportive role is arranged in the bottom of filter housing 100, and bracket 400 can increase as needed Add.

According to the needs of actual conditions, vertical or horizontal filter can be selected according to actual conditions such as bore, volumes, Horizontal pipeline.

Many advantages, such as piping filter of the utility model has structure simple to operation, and occupied area is small is real With the high filter plant of property.

Certainly, the above is only the preferred embodiments of the present utility model only, and therefore, it does not limit the patents of the utility model Range, all with the utility model specification and schema content institute, simply modification and equivalent structure change for it, should all similarly wrap Within scope of patent protection contained in the utility model.
