Embodiment Construction
[0039] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0040] 3 and 4 are cross-sectional views of examples of the self-cleaning filter system according to the present invention, showing the overall structure of the system, wherein Fig. 3 shows a normal operating state, Fig. 4 shows a cleaning operating state, and Fig. 5 6 is a sectional view showing only the filter element alone, and FIG. 6 is a perspective view showing the second cleaning element assembly installed outside the filter element.
[0041] The self-cleaning filter system of the present invention is similar to the traditional self-cleaning filter system, including: a housing 1, which is provided with a waste water inlet 1a and a filtered water outlet 1b, and its interior is divided into waste water entering through a disc-shaped partition 11. Space 1A and filter space 1B; filter screen 2, which is installed inside the waste water inlet...

The present invention relates to a self-cleaning filtering system which can solve clogging in a filter without separate operation and dismantling of the devices after detecting the clogging in the filter. According to the present invention, entire inside and outside walls of the filter element can be advantageously cleansed through a simple construction, by means of relative rotational and reciprocal linear movement of the filter element itself with regard to the nozzle in the cleansing member at the state in which the cleansing member is secured to the inside and outside of the filter element. Accordingly, troublesome works such as cleansing the outside wall of the filter element by injecting high pressure water from the outside after completely dismantling the devices can be removed, although the devices are used under bad conditions, so that labor and maintenance costs can be economized, and filtering efficiency can be enhanced because cleansing operation of the inside and outside walls in the filter element can be performed automatically without stopping the filtering operation of the devices.
Description
technical field [0001] The present invention relates to a self-cleaning filter system, and more particularly to a self-cleaning filter system capable of resolving a blockage in a filter after detection of the blockage without interrupting operation and without dismantling equipment. Background technique [0002] Wastewater discharged by industry (for example, factory wastewater or livestock wastewater) should be discharged with purification until it meets the prescribed standards listed in several regulations, so as to maintain the water quality in public waters. Wastewater treatment includes several treatments such as chemical treatment and biological treatment, and further mainly includes a filtration process to separate minute solid matter and suspended matter contained in waste water. [0003] Generally, a filtration process is performed by passing waste water including solid matter through a filter element provided with a plurality of fine pores through which solid matt...
