Problems solved by technology

However, the sewage collection and discharge effect of this kind of device is not good, and it is easy to discharge the sewage to be treated, which increases the cost of subsequent treatment
However, it is very difficult to adjust the height of the sewage collection pipe of this device on the water surface. Even if the adjustment rod is set to hang on the external fixture, the sewage collection pipe cannot be at the best height to collect sewage, and it is easy to put a large amount of water The water is also discharged from the reaction tank, which greatly increases the workload of the sludge pump, and fails to separate the sewage from the water, reducing the effect of sewage treatment

Embodiment 1

[0036] Such as Figures 1 to 3 The device for collecting floating objects on the water surface in the upgrading of sewage treatment shown in the figure includes a sewage collection and retention tank 1 and a PLC controller (not shown in the figure, which is used to remotely control the first water pump, solenoid valve, inflation and deflation) machines and sewage pumps).

[0037] A filter screen 9 is provided in the sewage collection and retention box 1, and the sewage collection and retention box 1 is respectively connected with the sewage inlet pipe 3 and the return outlet pipe 4, and the sewage inlet of the sewage inlet pipe 3 is located above the filter screen 9 The water inlet of the backflow outlet pipe 4 is located below the filter screen 9 and close to the bottom of the sewage collection and retention tank, and the outlet pipe 4 is connected with the first water pump 41 controlled by the PLC controller, by setting the first water pump and the backflow outlet The water...

Embodiment 2

[0047] Such as Figures 3 to 5 The device for collecting floating objects on the water surface in the upgrading of sewage treatment shown includes a sewage collection and retention tank 1 and a PLC controller (the PLC controller is not shown, and realizes remote control of the first water pump, solenoid valve, second water pump, two-way switch and sewage pump). The difference from Example 1 is:

[0048] The rotating part 51 includes a hose 513 with one end connected to the dirt inlet pipe 3 and a plurality of hard rings 5131 arranged in the hose 513 , and the hose 513 communicates with the dirt inlet part 52 . The head of the hose is made of hard material, and it is connected with the sewage inlet pipe by a flange, which is convenient for subsequent disassembly and installation. The distance between the mass rings is suitable, which can realize the bending of the hose and will not affect the suction of floating objects on the water. In this embodiment, since the hose is eas...

Abstract

The invention discloses a device for collecting water surface floating debris in sewage treatment upgrading and reconstruction. The device includes: a sewage collecting retention box and a PLC, the sewage collecting retention box is internally equipped with a filter screen, and is communicated with a sewage inlet pipe and a reflux outlet pipe, the sewage inlet of the sewage inlet pipe is located above the filter screen, the water inlet of the reflux outlet pipe is located under the filter screen and is close to the bottom of the sewage collecting retention box, and the reflux outlet pipe is connected to a first water pump controlled by the PLC, one end of the sewage inlet pipe outside the sewage collecting retention box is connected to a sewage inlet structure having a liquid level difference to the sewage collecting retention box, the sewage collecting retention box is internally equipped with a collected sewage discharge structure that is located above the filter screen and discharges the collected water surface floating debris, and the sewage inlet structure is movably disposed relative to the sewage inlet pipe. The device provided by the invention has the advantages of: simplestructure, easy collection of water surface floating debris, easy adjustment of water surface floating debris collecting liquid level, easy return of the collected sewage to a sewage pool, easy discharge of the collected water surface floating debris, and easy control and management.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a device for collecting floating objects on the water surface during sewage treatment upgrading and transformation. Background technique [0002] In the existing sewage treatment, the method of removing floating objects on the water surface (floating objects on the water surface refers to floating mud, floating foam, scum, and small floating debris in the sewage treatment tank) is mainly through manual salvage or special extraction. system. The manual salvage method has the problem of low efficiency, but the problem of fast and efficient cleaning is not well solved by using the existing special suction device. [0003] For example, the Chinese utility model patent with the application number CN201720368393.0 discloses a floating mud discharge device with a collection pipe, which includes: a floating mud collection pipe, a first mud discharge pipe, a second mud discharge...
