Problems solved by technology

In a working cycle, only the feeding and pressurized filtration processes are in the process of direct solid-liquid separation, and other processes are auxiliary processes, which greatly reduces the efficiency of the filter press; at the same time, if the filter cake is separated from the edge of the plate frame When the solid matter sticks, the filter chamber will be poorly sealed, the pressurized filtration pressure will be insufficient, and the injection of the masterbatch will be affected; overall, the filter press still has intermittent operation, low production efficiency, high labor intensity, and rapid loss of filter cloth , troublesome installation of filter cloth, etc.

Abstract

The invention relates to a solid and liquid separation device for sewage. The solid and liquid separation device comprises a stander, a filter barrel supported by the stander, an upper filter barrel cover which can move in the filter barrel up and down, a lower filter barrel cover, a moving device of the lower filter barrel cover and a filtrate inlet connected to the filter barrel. The solid and liquid separation device has a simple structure, high working efficiency, a good solid and liquid separation effect and high automation degree.

Description

(1) Technical field [0001] The invention relates to a device used for solid-liquid separation of sewage in the environmental protection industry. (2) Background technology [0002] At present, in the current process of industrial sewage treatment, the purpose of rapid separation is mainly achieved through pressure difference; the filter equipment is generally divided into two types: vacuum and pressurized. There are press filter, press, dynamic filter and rotary type etc. [0003] The filter device of the vacuum filter is installed on the hollow shaft by several pieces of filter screen. The cavity of the filter screen is connected with the filtrate hole of the hollow shaft. Drying area, filter cake shedding area. When the filter screen passes through the filter area, the cavity of the filter screen is connected to the vacuum pump. Under the action of the vacuum pump, the inner and outer layers of the filter screen form a pressure difference, the solid and liquid are separa...
