Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In order to solve the technical problem of how to filter the pipeline, please refer to fig. 1-4, the present embodiment provides the following technical solutions:

a drainage pipeline device for municipal works, includes filter tube 1, and water inlet 2 has been seted up to filter tube 1's upper end, and delivery port 3 has been seted up to its lower extreme, and butterfly valve 21 is installed to water inlet 2 department, and water inlet 2 and delivery port 3 all pass through flange dish and municipal works's drainage pipeline sealing connection.

The filter tube 1 is internally provided with a first piston 11, a filter screen 12 and a second piston 13 from right to left in sequence, the first piston 11, the filter screen 12 and the second piston 13 are connected through a piston rod 14, one end of the piston rod 14 penetrates through the filter tube 1 and is connected with a pushing plate 15, side ends of the first piston 11, the filter screen 12 and the second piston 13 are respectively sleeved with a sealing ring 17, and the sealing rings 17 are in fit connection with the inner wall of the filter tube 1.

The sealing ring 17 is provided to effectively seal the first piston 11, the filter screen 12 and the second piston 13 when moving in the filter tube 1, and prevent leakage of waste water, because the sealing ring 17 has elasticity, and radial stress can be generated when moving, so that the edge of the sealing ring is tightly attached to the inner wall of the filter tube 1.

Specifically, when the waste water that city operation and resident life produced gets into filter tube 1 from water inlet 2, because first piston 11 is located the upper end of edulcoration pipe 5 and seals edulcoration pipe 5 for the waste water discharges from the another side, and the waste water can be through the filtration of filter screen 12 certainly this moment, can intercept impurity such as sand grain in the waste water, prevents impurity from discharging from delivery port 3, reduces the risk of pipeline jam.

In order to solve the technical problem of how to remove impurities from a pipeline, referring to fig. 1-4, the present embodiment provides the following technical solutions:

The filter tube 1 is located the side of water inlet 2 and has offered clean mouthful 4, and filter tube 1 outer wall fixed mounting has cylinder 16, and the output and the push plate 15 fixed connection of cylinder 16 still have offered edulcoration pipe 5 in filter tube 1 lower extreme, and edulcoration pipe 5's bottom is sealed and the side has offered and has been arranged miscellaneous mouthful 51, and edulcoration pipe 5 internalization is equipped with pivot 52, and pivot 52 external fixation has helical blade 53, and the one end fixedly connected with motor 54 of pivot 52.

The rotating shaft 52 and the spiral blade 53 are arranged to prevent impurities such as sand particles from being accumulated on the top of the impurity removing pipe 5 to cause blockage.

Specifically, when the impurity at the front end of the filter screen 12 is excessively accumulated, the actuating cylinder 16 drives the pushing plate 15 to move, the pushing plate 15 drives the first piston 11, the filter screen 12 and the second piston 13 to move through the piston rod 14 until the first piston 11 moves away from the upper end of the impurity removing pipe 5, and the second piston 13 moves to the side end of the water outlet 3 to seal the impurity removing pipe, at the moment, the filter screen 12 is positioned at the front end of the cleaning port 4, and the external cleaning equipment is in sealing connection with the cleaning port 4, so that the cleaning equipment can flush the filter screen 12 through the cleaning port 4, sand and other impurities are prevented from being stuck on the filter screen 12, and meanwhile, the impurities such as sand and the like in the front of the filter screen 12 can be flushed into the impurity removing pipe 5 and finally discharged from the impurity discharging port 51.

The working principle is that when the drainage pipeline device for municipal works is used, when wastewater generated by urban operation and resident life enters the filter pipe 1 from the water inlet 2, the first piston 11 seals the impurity removing pipe 5 at the moment, so that the wastewater can only pass through the filter screen 12 to be discharged from the water outlet 3, the filter screen 12 can intercept impurities such as sand particles in the wastewater and prevent the impurities from entering the drainage pipeline to cause blockage, if the impurities in the filter pipe 1 are accumulated excessively, the butterfly valve 21 is closed to prevent the discharge of the wastewater, then the air cylinder 16 is started to drive the pushing plate 15 to move, the pushing plate 15 drives the first piston 11, the filter screen 12 and the second piston 13 to move through the piston rod 14, at the moment, the filter screen 12 can push and concentrate the impurities at the front end of the impurity removing pipe 5 until the water outlet 3 is sealed and the impurity removing pipe 5 is opened, the external cleaning equipment is connected with the cleaning port 4, so that the cleaning equipment can flush clean water from the cleaning port 4 to flush the filter screen 12 into the impurity removing pipe 5, and the starting motor 54 drives the rotating motor 52 and the spiral blade 53 to rotate, so that the sand particles can be automatically transported to the position of the inner part of the impurity removing pipe 51 to be prevented from being blocked.
