Embodiment Construction

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-2 As shown, the first rain discarding device of the present invention includes a well body 1 and a water inlet pipe 2, a water outlet pipe 3 and an abandonment pipe 4 arranged in the horizontal direction on the well body, and the water inlet pipe 2 and the water outlet pipe 3 are arranged on the well body 1 The two radial ends of the circumference have corresponding heights. The height of the discarding pipe 4 is lower than that of the water outlet pipe 3 , and the well body 1 is provided with a well cover 12 . The well body 1 is provided with a filter device at the outlet pipe 3. The filter device is a filter cartridge 6. The filter cartridge 6 includes a peripheral wall 7 with an arcuate cross-section, an upper cover 8 and a bottom 9 connected to the upper and lower ends of the peripheral wall, and the arc surfac...

Abstract

The invention discloses a first rain abandonment device, which is characterized in that it is a first rain abandonment device, which is characterized in that it includes a well body and a water inlet pipe, an outlet pipe and an abandonment pipe arranged horizontally on the well body, The height of the jettison pipe is lower than the water outlet pipe, the well body is provided with a filtering device at the water outlet pipe, and the well body is provided with a buoy restrictor valve at the discard pipe; the buoy restrictor valve includes a mounting plate, The pipe cover, the buoy and the rod-shaped connector hinged with the mounting plate, the pipe cover and the buoy are connected to the end of the rod-shaped connector and are located on both sides of the jettison in the initial state, and the two sides of the rod-shaped connector are respectively set There are an initial state regulating device and a closing limit device, and the buoy restrictor valve is connected with the well body through a mounting plate. The invention is simple in structure, easy to install, can complete the automatic discharge of pollutants in the early stage, and filter the collected rainwater in the later stage, without the need for electric devices, and is safe, environmentally friendly, energy-saving and durable.

Description

technical field [0001] The present invention relates to rainwater pretreatment, in particular to a primary rainwater discarding device. Background technique [0002] Research at home and abroad has proved that the pollution of rainwater runoff in the early stage of rainfall is more serious, the initial rainwater is mixed with a large amount of dust and sediment, and the content of organic pollutants is high, and the quality of rainwater is very poor. The technology of recycling is the key. At present, most of the initial rainwater runoff is disposed of by abandoning the flow. The abandoned rainwater should be treated, such as being discharged into the municipal sewage pipe network (or the rain-sewage combined pipe network) for centralized treatment by the sewage treatment plant, etc. . [0003] The Chinese patent CN201334685 automatic capping type primary rain discarding equipment is composed of a fixed shaft, baffles, diversion troughs, heavy objects, water intake pipes, w...
