Disc filter filtrate steam-water separation device

Abstract

The invention relates to a disc type filtrate steam and water separation device of a filter. The disc type filtrate steam and water separation device comprises an adsorption system, a dehydrating system, an air blowing unloading system and an electric control system; the adsorption system comprises an adsorption liquid discharging tank, an adsorption vacuum pipe, an adsorption vacuum pump, an adsorption vacuum venting pipe, an adsorption liquid discharging pipe and an adsorption flap valve; the adsorption liquid discharging tank is connected with the filter, the dehydrating system comprises a dehydrating liquid discharging tank, a dehydrating vacuum pipe, a dehydrating vacuum pump, a dehydrating vacuum venting pipe, a dehydrating liquid discharging pipe and a dehydrating flap valve; the dehydrating liquid discharging tank is connected with the filter, the air blowing unloading system comprises an air blowing pipe, a gas storage tank and a blower. The air blowing pipe is provided with an air volume control valve, and a blow-down valve is arranged at the bottom of the gas storage tank. Dehydrating and absorption in a filtering process are independently finished, and the difficult problem that the size of a filtrate tank depends on the area of the filter in a traditional process is solved, so that the process configuration is more reasonable, the plant constructing cost is lower, water and electricity cost as well as consumption of devices and spare parts are reduced.

Description

Technical field [0001] The invention belongs to the technical field of mineral processing equipment, and particularly relates to a disc filter filtrate vapor-water separation device. Background technique [0002] The traditional filter auxiliary system completes the collection and delivery of the filter filtrate by means of a filtrate cylinder, a steam-water separator and a filtrate water pump. The filtrate cylinder is a closed metal container with partitions inside to promote the separation of air and filtrate; its side wall is connected with the filter by pipes, and the upper and lower ends are respectively connected with a steam-water separator and a filtrate pump. The upper part of the filtrate tank is equipped with a safety valve to prevent excessive water accumulation in the filtrate tank, causing water to enter the vacuum pump. The size of the filtrate tank depends on the area of ​​the filter used. Corresponding to different filtration areas, there must be a filtrate tan...

AI Technical Summary

Problems solved by technology

Limited by the space of the factory building, if the height difference between the filter platform and the vacuum pump platform is small, less than 10.5 meters, it will cause difficulty in draining the steam-water separator. A centrifugal pump is needed to help the steam-water separator drain. Each filter is equipped with one The centrifugal pump and an 11KW motor not only cause waste of water and electricity, but also increase the consumption of equipment and spare parts

The power consumption of filtration system equipment accounts for 54% of the total power consumption of the whole workshop, which affects the cost accounting and economic benefits of the workshop

In particular, because the effusion in the vacuum pump cannot be removed smoothly, the wear of the impeller, steam leakage and water leakage will aggravate the wear of the impeller, and even lead to the damage of the vacuum pump, forming a vicious circle, which will eventually lead to the water content of the end product concentrate powder exceeding the standard, affecting Filtration quality
