Ceramic disc type filtering machine

Abstract

The invention provides a ceramic disc type filtering machine. The ceramic disc type filtering machine comprises a white water groove, a ceramic filtering disc, a hollow collecting pipe and a driving device, wherein a part of the ceramic filtering disc is immersed into the white water groove; the ceramic filtering disc is formed by a plurality of sector-shaped ceramic filtering units which are distributed along the circumferential direction; each ceramic filtering disc is hollow; a plurality of micro-filtering holes are distributed in each ceramic filtering unit; the hollow collecting pipe is arranged on the center axis of the ceramic filtering disc in a penetrating manner; a hollow chamber of the ceramic filtering disc is communicated with an inner cavity of the hollow collecting pipe; the driving device is connected with the ceramic filtering disc and drives the ceramic filtering disc to rotate around the axial direction. The ceramic disc type filtering machine provided by the invention has the advantages of good filtering effect, reasonable configuration, stable operation and low cost.

Description

technical field [0001] The invention relates to a white water treatment device in the papermaking industry, in particular to a ceramic disc filter used in the white water treatment device in the papermaking industry. Background technique [0002] With the increasing scarcity of water resources and the increasing demand for industrial water, the recycling of treated wastewater has become an important part of water environmental protection projects. Especially in the field of papermaking, water resources have become a key factor hindering the development of the papermaking industry and a core issue for the survival and development of enterprises. [0003] Since papermaking enterprises are large water users, the amount of circulating white water is large. With the recycling of waste paper, there are more and more fine fibers in the white water, and the turbidity of the white water is increasing. General methods such as coagulation sedimentation and disc filter are used to recov...

Problems solved by technology

[0003] Since papermaking enterprises are large water users, the amount of circulating white water is large. With the recycling of waste paper, there are more and more fine fibers in the white water, and the turbidity of the white water is increasing. General methods such as coagulation sedimentation and disc filter are used to recover White water, with a high concentration of white water, is reused in the production of spray screens, which has a great impact on production and high cost, resulting in a large amount of clean water and a large amount of sewage treatment; especially the low concentration of white water in toilet paper, the amount of white water produced per ton of paper is large, regardless of the use of the above Which method, the treatment cost is high, and the white water treatment effect is not ideal, resulting in excess white water being discharged to the sewage treatment plant, wasting a lot of water resources, and bringing great negative pressure to the environment
