Spiral-flow-type automatic mud scraping and filtering system and method

Abstract

The invention relates to a spiral-flow-type automatic mud scraping and filtering system and method. The system comprises a filtering device and a control system, the filtering device comprises a shell, the shell is provided with a water inlet pipe, a water outlet pipe and a mud discharge pipe, and the water inlet pipe is of a diameter varying structure so that inlet water can generate spiral flow;an air inlet pipe is connected to the water outlet pipe, a water inlet electromagnetic valve, a water outlet electromagnetic valve, an air inlet electromagnetic valve and a mud discharge electromagnetic valve are arranged on the water inlet pipe, the water outlet pipe, the air inlet pipe and the mud discharge pipe respectively, and an air pump and all the electromagnetic valves are connected withthe control system separately; the shell is internally provided with a filter and an automatic mud scraping device, the automatic mud scraping device is mainly composed of a mud scraper arranged on the filter, a mud scraper moving track, a signal converter arranged outside the shell and a power driving device used for driving the mud scraper to reciprocatingly scrape mud, and the control system is connected with the power driving device through the signal converter. By means of the system and method, impurities in water can be effectively filtered out, the effect and efficiency of removing accumulated impurities can be improved, and long-term stable running of the filtering device is guaranteed.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a swirl type automatic mud scraping filter system and method. Background technique [0002] Traditional heating methods based on relatively concentrated and large-scale coal-fired boiler heating methods often consume a large amount of coal resources, which is likely to cause environmental pollution and energy waste. In recent years, water source heat pump technology has been widely concerned and applied to heating and cooling inside buildings due to its advantages such as high operating efficiency, low cost, energy-saving friendliness, stable and reliable operation, and significant environmental benefits. The water source heat pump technology is mainly based on the principle of water circulation and heat exchange to achieve continuous cooling and heating. The sand content in the water body is a key factor affecting the heat exchange efficiency, service life and stable ope...
