Detailed Description

The following describes in further detail embodiments of the present invention with reference to the accompanying drawings. The following embodiments are provided to illustrate the present invention, but are not intended to limit the scope of the present invention.

As shown in figure 1, the anti-blocking wall-hung negative pressure collecting well comprises a well body 1, a track cabin 3, a water suction port 4, a floater 5, a negative pressure pipe 6 and a negative pressure meter 7. A plurality of filtering holes are arranged on the side wall of the track cabin 3. And a plug for plugging the opening end of the negative pressure pipe in the track cabin 3 and a floater 5 connected with the plug are arranged in the track cabin 3. A negative pressure meter 7 is arranged on the negative pressure pipe 6 outside the track cabin 3. Oil separating grooves 2 and a track cabin 3 are respectively arranged at two sides in the well body 1, and the middle is separated by a grid mesh 8. The oil separating tank 2 is separated by a partition plate 10, the left side is a filtering side, and the right side is an output side. The weight of oil is lighter than that of water, oil in sewage can slowly rise, and the partition plate 10 is arranged to separate the oil on the upper side of the water surface. The liftable grid frame 9 is arranged on the filtering side, so that the installation space is reduced, impurities in sewage are removed in multiple ways, and the stability of a negative pressure system and rear-end water treatment equipment is ensured; the side plate 17 on the output side is provided with a water outlet pipe 11. The bottom of the water outlet pipe 11 is lower than the pipe orifice of the water outlet pipe 11 and lower than the liquid level in the groove. A water inlet 12 is arranged on the side wall of the well body 1 above the grid frame 9, and a water outlet 13 is arranged on the side wall of the well body 1 at the side of the track cabin 3. The water outlet 13 is connected with a rear-end negative pressure station through a negative pressure pipe, the negative pressure station and the negative pressure pipe are in a vacuum negative pressure state, and the plug of the floater 5 is tightly sucked under the action of negative pressure suction force, so that sewage cannot pass through the water suction port 4 to the rear end of the system. Along with the gradual rise of the liquid level in the negative pressure well, the buoyancy generated in the track cabin 3 is gradually increased, when the buoyancy generated by the floater 5 is larger than the suction force generated by the water suction port 4 to the plug due to the negative pressure, the plug rises along with the floater 5, and the sewage in the well body 1 is conveyed to the rear end under the action of the atmospheric pressure; when the liquid level in the well body 1 reaches the low level again, the water suction port 4 is blocked again under the action of the gravity of the floater 5 and the suction force in the negative pressure pipe 6. The top surface of the well body 1 is provided with an upper cover 14. The well body 1 is of a rectangular or semi-cylindrical structure.

The top of the track cabin 3 is provided with a top plate 18, and the top plate 18 is fixedly connected with the inner wall of the well body 1 through a top plate fixing support 15.

As shown in fig. 2, an angle iron bracket 16 is arranged at the bottom of the well body 1.

As shown in fig. 3, the grill frame 9 is provided with a handle 19 for easy lifting and cleaning.

The working principle is as follows: after impurities such as rice grain residue and hair are removed from sewage entering from the water inlet 12 through the liftable grid frame 9, floating oil is removed from the sewage in the oil separation tank 2 and the sewage is temporarily stored in the negative pressure well. The high water level floater 5 in the well is opened, sewage is discharged from the negative pressure pipe 6 through the water suction port 4, and the low water level in the well, the floater 5 blocks the water suction port 4.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
