Sewage filtering and taking device for sewage source heat pump system

Abstract

The invention relates to a sewage filtering and taking device for a sewage source heat pump system. The sewage filtering and taking device comprises a sinking pump room (30), a water taking well (40), a trunk sewer (50), an outer filter cartridge (1), outer filtering holes (1-1) formed in the outer filter cartridge (1), a water suction pipe (2), inner filtering holes (2-1) formed in the water suction pipe (2), a boss (13), an anchor cone (14), a guide rod (3) and the like; the sewage filtering and taking device further comprising an outer filter cartridge lifting device, an outer filter cartridge decontamination device and an inner filter cartridge decontamination device, wherein the outer filter cartridge lifting device consists of a lifting rope (6), a lifting beam (7), a pulley (8), a winch (10) and a lifting button (11); the outer filter cartridge decontamination device consists of a sweeping ring (5), a sludge scraper (15) and a water cleaning ring (18); the inner filter cartridge decontamination device consists of four arc-shaped sludge scrapers (19) embedded on the inner wall of the outer filter cartridge (1). The sewage filtering and taking device can be directly soaked in a sewage culvert or a main canal, a drainage pool and a buffer pool are not needed to be built, river closure is not needed to be carried out on the sewage, and the sewage filtering and taking device can be installed only by punching on the top of the main canal. The sewage filtering and taking device is convenient to install and maintain, safe in construction and less in investment, is capable of avoiding the sewage source heat pump system being blocked, is stable in water taking, can prevent secondary pollution, and is reliable in filtering quality, rapid in sewage removal and long in service life.

Description

[0001] Technical field: [0002] The invention relates to a filter water intake device, in particular to a sewage filter water intake device used in a sewage source heat pump system. Background technique: [0003] Urban sewage can be used as a low-level cold and heat source for heat pumps, but the water quality of urban sewage is very bad, containing a large amount of solid suspended impurities, which can easily block water pumps, pipelines and heat exchange equipment. Therefore, urban sewage Before entering the heat pump system for heat exchange, coarse filtration is generally required. The existing coarse-effect filtration equipment or processes all have the following problems: 1. The coarse-effect filtration device is installed after the outlet of the sewage pump, represented by various types of "anti-blocking machines", which cannot provide protection for the sewage pump. It is easy to block the sewage pump, and it is necessary to build a drainage pool and a buffer pool...

Problems solved by technology

The existing coarse-effect filtration equipment or processes all have the following problems: 1. The coarse-effect filtration device is installed after the outlet of the sewage pump, represented by various types of "anti-blocking machines", which cannot provide protection for the sewage pump. It is easy to block the sewage pump, and it is necessary to build a drainage pool and a buffer pool; 2. The coarse-effect filter device is installed at the water inlet end of the sewage pump, represented by the "immersion filter device", which requires high flow and water depth in the sewage pipe area. Installation needs interception, maintenance is more troublesome
