A multipurpose machine for filtering, concentrating and washing

Abstract

The invention provides a multipurpose machine for filtration, concentration and washing. The machine comprises a base, a front bracket, a rear bracket, a front support plate, a rear support plate, a hydraulic oil cylinder, an oil cylinder seat, a movable pressure plate, an impeller, a filter plate, a washing filter plate, a center shaft, a reduction gearbox, a motor, a regulation valve, a filtrate branch pipe and a filtrate manifold, wherein the front and rear brackets are arranged on the base; the hydraulic oil cylinder is arranged on the front bracket through the oil cylinder seat; one end of the center shaft is arranged on the movable pressure plate in a sleeving manner, and horizontally penetrates through the impeller, the filter plate, the washing filter plate and a rear support seat in sequence, and the other end of the center shaft is connected with an output shaft of the reduction gearbox; the motor and the regulation valve are arranged on the reduction gearbox. The multipurpose machine is compact in structure; materials can be continuously fed, and filter cakes can be discharged during filtration, so that the machine is high in production efficiency and productivity; the machine automatically runs, so that the operation intensity is low; the machine is convenient to operate and maintain, and low in production cost and has the energy-saving effect, and the consumption is lowered; a cross flow filtration mode is adopted, so that a filter cloth regeneration function is realized; the machine is wide in application range.

Description

technical field [0001] The invention relates to a multi-purpose machine, in particular to a multi-purpose machine for filtering, concentrating and washing. Background technique [0002] Most of the current filtration, fine filtration, microfiltration and press filtration are filter cake filtration methods. The so-called filter cake filtration refers to the liquid-solid separation of the slurry through the filter medium (filter cloth or filter membrane) under the action of vacuum suction or the pressure difference of the slurry pump. When the solid intercepted on the surface of the filter medium increases to a certain thickness (that is, the compactness of the filter cake increases, the air permeability and liquid permeability of the filter cake are lower than the air permeability and liquid permeability of the filter medium), it will be transformed into filter cake filtration. At this time, the filter cloth is only used as a skeleton, and has no filtering effect. As the fi...

Problems solved by technology

[0004] The traditional settling tank thickener has a large processing capacity, but it occupies a large area, the equipment cost is high, and the settling speed is slow. Most of the settling and thickening slurry needs to be added with flocculants, which increases the system investment and production costs. The slurry is difficult to handle in the subsequent liquid-solid separation process, mainly because the jelly of the flocculant can easily block the filter cloth

There are also some slurries with light solid density (specific gravity) and fine particle size, which are difficult to settle and concentrate. Such slurries cannot be separated by a settling tank thickener.
