Filter-dryer

Abstract

The invention relates to a filter-dryer, in particular to filtering and drying integrated equipment for powdery materials. The filter-dryer comprises a machine body and a material pumping pipe. Proper filter cloth is laid on a supporting frame and fixed, then materials are fed through a feeding pipe, a valve of a vacuumizing pipe is opened for vacuumizing after materials are fed, water in the materials is pumped away through the filter cloth to achieve dryness of the materials, hot water is fed through the feeding pipe for washing, the process is carried out repeatedly, after the materials are washed clean, a valve of a steam pipeline is opened, steam is introduced for drying, and after drying, a valve of the material pumping pipe is opened for vacuum material pumping. The filter-dryer is safe, efficient, low in cost and small in energy consumption, achieves integration of material filtering, washing, drying and discharging, and has great popularization significance.

Description

technical field [0001] The invention relates to a filtering and drying machine, in particular to an integrated filtering and drying equipment for powder materials. Background technique [0002] There are many equipments for solid and liquid filtration, washing and drying in the market. The filtration and washing equipment includes filter press, microporous filter, pressure filter and other equipment, and the drying equipment includes various ovens and dryers. However, most of the existing varieties have the following defects: firstly, the washing, filtering, drying and other processes are carried out separately, which is inconvenient to operate, and at the same time, due to the need for multiple equipment, the cost is high and the energy consumption is high; Medium turnover, the risk of material pollution increases, and the recovery rate of materials is difficult to guarantee, the production efficiency is low, and time and resources are wasted. For example, using a filter ...

Problems solved by technology

However, most of the existing varieties have the following defects: firstly, the washing, filtering, drying and other processes are carried out separately, which is inconvenient to operate, and at the same time, due to the need for multiple equipment, the cost is high and the energy consumption is high; Medium turnover, the risk of material pollution increases, and the recovery rate of materials is difficult to guarantee, the production efficiency is low, and time and resources are wasted

For example, using a filter press to filter and wash, the filtered and washed materials need to be taken out of the filter press, which requires manual work or equipment. At the same time, some materials will inevitably be lost in the process of taking out. After taking out, they need to be loaded into drying equipment. It also requires manpower and equipment, and at the same time, it is inevitable that some materials will be lost. In the process of material turnover, because the materials will come into contact with the outside world, the risk of being polluted by the outside world will increase, which is a waste of manpower and material resources, and the recovery rate of materials cannot be guaranteed. purity
