Description

Filtration formula municipal drainage structures

Technical Field

The utility model belongs to the technical field of the municipal drainage pipe, a filtration formula municipal drainage structure is related to.

Background

A large amount of sewage flows into the urban underground drainage pipe, and a filter screen is usually installed in the drainage pipe to prevent the drainage pipe from being blocked.

For example, chinese patent literature discloses a municipal drainage pipe capable of preventing clogging [ application No.: 201610398070.6, respectively; authorization notice number: CN105840918A ], the concrete structure of which comprises a tubular pipe body and a filter pipe transversely fixed in the pipe body and in a conical shape, the diameter of the filter pipe gradually increases from left to right, the right end of the filter pipe is provided with a circular flange, the outer side wall of the flange is attached to the inner side wall of the pipe body, and the flange penetrates through a plurality of water through holes along the axial direction of the pipe body.

In foretell municipal drainage pipe that can prevent blockking up, this filter tube is transversal installs in the body of drain pipe alone, and the dirt that is blockked down by the drain pipe like this can remain on the filter tube, needs often clear up the filter tube just can keep unobstructed of drain pipe, and it is troublesome and with high costs to maintain, and a large amount of filter tubes need consume a large amount of manpower and materials in a city.

Disclosure of Invention

The utility model aims at the above-mentioned problem that exists among the prior art, provide a simple structure, not only can prevent that the drain pipe from blockking up still make things convenient for the filtration formula municipal drainage structure of dirt emission.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a filtration formula municipal drainage structure, is the drainage import including the drain pipe that is vertical setting and the upper end of this drain pipe, the outer wall at the middle part of drain pipe on have and be radial setting and the outlet pipe joint that is linked together with the drain pipe, its characterized in that, the lower tip of drain pipe have the circulation pipeline, drain pipe and circulation pipeline between have the break-make structure, the drain pipe in be provided with filter equipment, drainage import and outlet pipe connect and pass through filter equipment intercommunication.

The filter type municipal drainage structure mainly has an on-off structure between the drainage pipe and the circulation pipeline, and the drainage pipe and the circulation pipeline are communicated or separated by the on-off structure; when dirt needs to be discharged, the on-off structure enables the drain pipe to be communicated with the circulation pipeline, the circulation pipeline can be used for discharging the dirt, the discharging is simple, and the maintenance cost is low; when the water-saving device is normally used, the on-off structure can separate the drainage pipe from the circulation pipeline; be provided with filter equipment in the drain pipe, this filter equipment prevents that the drain pipe from blockking up, makes things convenient for the emission of drain pipe, can keep the unobstructed of drain pipe.

In foretell municipal drainage structures of filtration formula, the break-make structure include the partition panel, the partition panel level be located between drain pipe and the circulation pipeline, partition panel and drain pipe fixed coordination. When the water-saving valve is used at ordinary times, the on-off structure is used for blocking the circulation of the water drainage pipe and the circulation pipeline.

In foretell municipal drainage structures of filtration formula, the lower tip of drain pipe have the intercommunication portion that is the back taper, the drain pipe pass through the intercommunication portion and communicate with the runner pipe way, the edge of partition panel be the back taper face, the partition panel pass through the intercommunication portion of back taper face and drain pipe and lean on fixed coordination. The purpose of this arrangement is to stabilize the fixed fit structure of the partition panel in the communication portion of the drain pipe.

In foretell municipal drainage structures of filtration formula, the middle part position of partition panel have the flip board that is the rectangle form, flip board pass through on the articulated partition panel of round pin axle. Pile up on the partition panel and when influencing the drain pipe filter clogging, will overturn the apron and overturn to vertical state on the partition panel, during the dirt flow direction circulation pipeline, take away the dirt circulation by the circulation pipeline, make things convenient for the dirt clearance.

In foretell municipal drainage structures of filtration formula, filter equipment include that filter and both ends are the filter vat of opening form, the same axial of filter vat wear to locate in the drain pipe, the section of thick bamboo wall of filter vat on set up a plurality of and cross filtration pore one, every crosses filtration pore homogeneous phase and is in outlet pipe joint relatively, the filter set up in the bucket mouth department of the upper end of filter vat, the filter on the equipartition have filtration pore two, every crosses in the bucket mouth of two homogeneous phases of filtration pore relatively being in the upper end of filter vat, the filter vat under the tip have the joint portion of back taper, the filter vat pass through the intercommunication portion screens cooperation of joint portion and drain pipe, when the filter vat is in the drain pipe, and the joint portion and the partition panel of this filter vat lean on the cooperation. The second filtering hole on the filtering plate is used for initial filtering, the first filtering hole on the filtering barrel is used for delicate filtering, the filtering effect is good, and the blocking of the drain pipe can be effectively prevented.

In the above filtering municipal drainage structure, an elastic rubber gasket is arranged between the filter plate and the filter barrel. The elastic rubber gasket plays a role of elastically leaning against buffering and energy absorption.

Compared with the prior art, this filtration formula municipal drainage structure's advantage does: simple structure, the filter effect is better, and when the dirt impurity of aquatic is piled up on the partition panel, the upset effect through the flip board enables dirt impurity flow direction circulation pipeline and takes away the dirt circulation by the circulation pipeline, makes things convenient for dirt impurity clearance, convenient to use, and the maintenance cost is lower, need not consume a large amount of manpower and materials.
