Integral non-negative-pressure water purifying-supplying equipment

Abstract

The invention discloses integral non-negative pressure water purifying-supplying equipment. The integral non-negative pressure water purifying-supplying equipment comprises a non-negative-pressure tank, a purifier, a back flushing system and a control device, wherein the water inlet of the non-negative-pressure tank is connected with a raw water tube; the water outlet of the non-negative-pressure tank is communicated with the water inlet of the purifier in three paths; the water outlet of the purifier is connected with a water supply pipeline; a filtering element is arranged in the purifier; a drain outlet is formed in the bottom of the purifier; a drain valve is arranged on the drain outlet; the water outlet of the purifier is arranged on the side wall or the top of the purifier; the height difference between the water outlet of the purifier and the bottom drain outlet is taken as a sewage falling back-flushing pressure; the water supply pipeline which is connected with the water inlet of the purifier is connected with a bypass pipe; a back-flushing valve is arranged on the bypass pipeline. By adopting the integral non-negative-pressure water purifying-supplying equipment, a water purifying function is provided on the basis of supplying water, an automatic back-flushing function is formed by means of the height difference and an electric control device, automatic back flushing is realized through the filtering element, and replacement and overhauling are avoided.

Description

technical field [0001] The invention relates to the field of sewage purification, in particular to a water supply device with integrated water supply without negative pressure. Background technique [0002] The non-negative pressure water supply equipment is a product of the 1970s and has a history of 40 to 50 years. According to the speed of urban development and the outdated public supporting facilities, it can no longer keep up with the current development needs, and because the current waterworks are mostly from the previous Old-fashioned technology in the 1960s and 1970s, according to relevant national data reports, tap water in more than half of China's cities is not up to standard. According to the current secondary water supply, there are many community reservoirs and water tanks that are exposed, and the microorganisms seriously exceed the standard, especially some water. The property management of the district cannot keep up, and the reservoirs and water tanks have...
