Multi-layer filtering ceramic filter element and preparation process thereof

Abstract

The present invention provides a multi-layer filtering ceramic filter element and preparation process thereof. The ceramic filter element comprises a structural pipe, wherein an annular ceramic filter element body is fixed to the structural pipe, openings in the upper end and the lower end of the structural pipe communicate with the inner side and the outer side of the ceramic filter element body correspondingly; the upper end and the lower end of the outer side of the ceramic filter element body are sleeved with rotating wheels that are rotationally connected with the ceramic filter element body; a cleaning rod is connected between the upper rotating wheel and the lower rotating wheel, the outer side of the structural pipe and the outer side of the ceramic filter element are wrapped by a sleeve shell, the upper end and the lower end of the sleeve shell are both in threaded connection with the structural pipe, and the sleeve shell can be controlled to move up and down along the structural pipe by rotating the sleeve shell. Herein, the cavities are formed in the upper side and the lower side between the structural pipe and the sleeve shell, so that water flow can be controlled to directly flow out without passing through the filter element or flow out after being filtered by the filter element by adjusting the proportion of the upper cavity and the lower cavity; when the water flow directly flows out, the rotating wheel and the cleaning rod can be driven to clean and scrape the surface of the ceramic filter element, so that the switching between the cleaning effect of the filter element and the filtering function of the filter element on the water flow is realized. The filter element has a good development prospect.

Description

technical field [0001] The invention relates to the technical field of filtration, in particular to a ceramic filter core for multi-layer filtration and a preparation process. Background technique [0002] Filter element is a professional term for the function of filtration and purification. In order to purify the resources of the original fluid and the simple device for separating resources, the filter element is mainly used in the filtration industries such as oil filtration, air filtration, and water filtration. The filter element separates solid particles in liquid or gas, or uses The full contact of different material components can speed up the reaction time, which can protect the normal operation of the equipment or the cleanliness of the air. When the fluid enters the filter element with a certain size filter, the impurities are blocked, and the clean fluid flows out through the filter element. The liquid filter element makes the liquid (including oil, water, etc.) c...

Problems solved by technology

[0003] The filter element is widely used in daily life to filter various liquids, among which the filtration of kitchen water is the most common, through the purification of tap water through the filter element, the quality of drinking water can be improved, and the diseases caused by poor drinking water quality can be reduced, but the traditional filter element is used in During use, since the structure of the filter element filters the water body, it also hinders the flow of the water body, resulting in a reduction in the water output of the faucet. When washing vegetables, dishes, rice, etc., the normal demand for the water output flow is often not met, and with the For the use of the filter element, the surface of the filter element will accumulate filtered impurities, and it needs to be disassembled regularly to clean the filter element. The operation is inconvenient, and it is not very friendly to some women or the elderly with poor hands-on ability. It is often necessary to contact the master for on-site maintenance.
