Description

Technical Field

[0001] The utility model relates to the technical field of filtering equipment, in particular to a municipal drainage filtering equipment. Background Art

[0002] Municipal administration refers to the various administrative management work of the city, and also refers to market trade affairs. Urban management work includes industry and commerce, transportation, public security, culture and education, environment, sanitation, and infrastructure. Municipal drainage is the treatment and discharge of rainwater and sewage in the city. The rainwater and sewage generated in the city are generally collected and discharged through sewers.

[0003] The existing municipal drainage sewers are equipped with manhole covers, but in order to ensure the drainage volume and avoid water accumulation, the water inlet on the manhole cover is set very large, which causes a lot of garbage to enter the sewer. After a long period of accumulation, the garbage accumulates in the sewer, causing sewer blockage and leading to problems in the drainage system. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art by providing a municipal drainage filtration device, which is realized by the following technical solutions:

[0005] A municipal drainage filtration device comprises a ground, a manhole cover and a sewer pipe, wherein the ground is sunken to form a cavity, the manhole cover is arranged at the top of the cavity and is flush with the ground, the sewer pipe is opened at the bottom of the cavity, a filter tank is installed in the cavity, the filter tank is in the shape of a tank with an opening at the top, a filter screen is installed in the middle of the filter tank, and the sewer pipe is located directly below the filter screen. The utility model is further configured as follows: an opening inclined downward is opened on one side of the filter tank, a dirt collection box is placed at the bottom of the opening, and the dirt collection box is placed on the bottom wall of the cavity on one side of the sewer pipe.

[0006] The utility model is further configured as follows: a piston impact vibrator and a fixing seat fixed to the bottom of the vibrator are installed on one side of the bottom of the filter tank, and the fixing seat is fixed on the bottom wall of the cavity on the side of the sewer pipe away from the dirt collecting box.

[0007] The utility model is further configured as follows: the side wall of the dirt collecting box close to the sewer pipe is configured as a mesh structure, the bottom wall of the dirt collecting box is configured to be inclined downward toward the mesh structure, and lifting handles are fixedly installed on the tops of all side walls of the dirt collecting box except the mesh structure.

[0008] The utility model is further configured as follows: a shield is fixedly installed on one side of the bottom of the filter tank close to the vibrator, and the length of the shield is greater than the height of the vibrator.

[0009] The utility model is further configured as follows: the manhole cover is provided with a plurality of water inlets located just above the filter screen.

[0010] In summary, the beneficial technical effects of the utility model are:

[0011] The garbage that passes through the manhole cover is collected through the filter trough, and the rainwater and sewage fall into the sewer through the filter screen, avoiding the blockage of the sewer caused by garbage entering the sewer, thereby ensuring the normal operation of the drainage system; by setting an opening, the garbage accumulated in the filter trough will fall into the sewage collection box, thereby avoiding excessive accumulation of garbage on the filter screen affecting the filtration efficiency; the filter trough is vibrated by a vibrator to vibrate the garbage attached to the filter trough into the sewage collection box; the sewage in the sewage collection box is discharged through the mesh structure; and by setting a shield, the sewage is prevented from soaking the vibrator, thereby ensuring the normal operation of the vibrator.

[0017] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0018] Example

[0019] like Figure 1-4 As shown, a municipal drainage filtering device disclosed by the utility model comprises a ground, a manhole cover 1 and a sewer pipe 2, wherein the ground is sunken to form a cavity 3, the manhole cover 1 is arranged on the top of the cavity 3 and is flush with the ground, the sewer pipe 2 is opened at the bottom of the cavity 3, a filter tank 4 is installed in the cavity 3, the filter tank 4 is in the shape of a tank with an open top, a filter screen 5 is installed in the middle of the filter tank 4, and the sewer pipe 2 is located directly below the filter screen 5.

[0020] An opening 401 inclined downward is formed on one side of the filter tank 4 , a dirt collecting box 6 is placed at the bottom of the opening 401 , and the dirt collecting box 6 is placed on the bottom wall of the cavity 3 on one side of the sewer pipe 2 .

[0021] A piston impact vibrator 7 and a fixing seat 8 fixed to the bottom of the vibrator 7 are installed on one side of the bottom of the filter tank 4. The fixing seat 8 is fixed to the bottom wall of the cavity 3 on the side of the sewer pipe 2 away from the dirt collecting box 6.
