Embodiment Construction

[0017] Such as figure 1 As shown, the sewage inlet pipe 3, the exhaust hole 5 and the inspection hole 7 are set on the casing 1. A filter chamber 4 and two sewage lifters 2 are arranged in the box body 1 . The intelligent controller 8 is respectively connected with the filter chamber 4, the liquid level controller 6 and the sewage lifter 2 through lines. The filter chamber 4 is made of stainless steel, which is a screen frame mechanism. The bracket welded by angle steel is fixed in the box body 1 with bolts, and a cutting grinder is embedded in it for crushing sundries. The outlet end of the sewage inlet pipe 3 is located in the filter chamber. Above the net, the water inlet end of the sewage water inlet pipe 3 is located outside the casing 1. The sewage lifter 2 is arranged in the casing 1, and it is a kind of anti-clogging pump (commercially available product) with an automatic flushing valve. The discharge pipe 11 of the sewage lifter 2 is provided with a check valve 9 a...

Abstract

The invention relates to a municipal sewage filtering device and method. The municipal sewage filtering device comprises a box body, a sewage lifting device, a filtering chamber, a liquid level controller and an intelligent controller, wherein the sewage lifting device and the filtering chamber are arranged in the box body and are respectively connected with the intelligent controller arranged outside the box body by a circuit; the discharge pipe of the sewage lifting device is provided with a check valve and a gate valve; the filtering chamber is connected with a sewage inlet pipe; one end of the liquid level controller is arranged in the box body, and the other end of the liquid level controller is connected with the intelligent controller by a circuit; in the sewage filtering device, a sediment cutting and crushing machine can be started according to the quantity of the sediments in the filtering chamber; a washing device is started for washing the sediment powder in the filtering chamber according to the level of the liquid in the sewage box body; and the sewage lifting device is started for discharging the sediment powder and sewage. According to the invention, a sewage filter and discharge system can be controlled to carry out automatic collecting, filtering, crushing, washing, lifting, discharging in real time according to the need.

Description

technical field [0001] The invention relates to a sewage filtering device and method, in particular to an intelligent filtering and discharging device and method for urban sewage, especially suitable for environmental protection sites where various types of urban sewage and waste water cannot be discharged to indoor or outdoor drainage pipes by themselves. Background technique [0002] Environmental protection is a basic national policy of our country, and the environmental protection industry is one of the new economic growth points of the national economy. The state encourages and supports environmental protection equipment projects. At present, it is necessary to build storage and lifting equipment in places where the self-discharge of sewage and wastewater cannot be realized. Traditional sewage and wastewater storage and lifting equipment are mostly made of reinforced concrete masonry. In this way, not only the construction period is long and the construction is difficul...
