Embodiment Construction

[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings, and the following embodiments are given.

[0021] It consists of a dispensing device 6, a backwash system 7, and a lotion recycling system composed of a lotion pool 13, a circulation pump 12, and a lotion water pipeline 5.

[0022] Initial cleaning of the ceramic filter: After the filter is stopped, rinse the material on the tank body 1 and the ceramic plate 2, and discharge it through the discharge valve; add cleaning water through the cleaning water pipeline 4 to submerge the ceramic filter in the tank body 1 Plate 2, start the ultrasonic vibrator box 3 for ultrasonic cleaning; turn on the backwash pump 11, send clean water through the backwash valve 10 and filter 9 into the interior of the ceramic plate for backwashing from the inside to the outside, and at the same time, the metering pump 16 pumps the storage tank 15 The concentrated chemical cleaning agent...

Abstract

The invention belongs to the technical field of filters and in particular relates to a method and a device for cleaning a ceramic filter by recycling cleaning fluid. The cleaning method is characterized in that clear water in the previous steps is replaced by the cleaning fluid in a cleaning fluid pool from the second-time washing to the last-time washing. The device is characterized in that one end of a cleaning fluid pipeline is connected with the cleaning fluid pool through a circulating pump, and the other end of the cleaning fluid pipeline is connected with the upper part of a tank body; one end of a drainage pipeline is connected with the cleaning fluid pool, and the other end of the drainage pipeline is respectively connected with the bottom and top of the tank body through a bottom flow valve and an overflow valve. Compared with the prior art, the invention has the advantages that the using amount of cleaning water can be reduced by over 60 percent, the service life of a ceramic plate is prolonged, the productivity of a filter is improved, the using amount of chemical agents is reduced, the production cost is reduced, and the device has low sewage discharge amount and is energy-saving and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of filters, and in particular relates to a cleaning method and device for recycling a cleaning liquid for a ceramic filter. Background technique [0002] The ceramic filter is a solid-liquid separation equipment designed by using microporous ceramic plates as the filter medium and applying the principle of microporous water-permeable and air-tight capillary effect. It has the characteristics of high efficiency, energy saving, clear filtrate, full utilization of water resources, and high degree of automation. With the increasing shortage of natural resources and the finer grinding of concentrates, the problem of micropore blockage of ceramic filter plates has become more and more prominent, which has become one of the main factors restricting the production capacity of ceramic filters. [0003] Therefore, solving the clogging of the ceramic plate and restoring its regeneration ability has become an important ...
