Automatic continuous band solid-liquid segregation apparatus

Abstract

The invention discloses an automatic continuous band solid-liquid segregation apparatus, comprising a blanking system, a conveying system, an unloading system, an air intake system, an induced draft fan system, an air-liquid separation system, an air purification system and a control system. Mixture is paved on a conveyor belt, high-speed flow air generated by an induced draft fan passes through the mixture on the conveyor belt, the solid surface of the mixture rubs with high-speed air to raise temperature, thereby quickly evaporating the liquid state part into gas state which is taken away byhigh-speed air to obtain separated solid phase products, besides, air discharged by the induced draft fan passes through the air-liquid separation system to obtain liquid phase products. The invention has high degree of automation, continuous operation, high work efficiency, wide field of application, low manufacturing and using cost of equipment and pure separated solid state products.

Description

technical field [0001] The invention relates to the field of solid-liquid phase separation machinery, specifically a belt-type device capable of automatically and continuously separating solid-liquid phases, which can be widely used in industries such as chemical industry, environmental protection, coal mines, papermaking, metallurgy, and tanning. Solid-liquid separation. Background technique [0002] At present, the main methods used in solid-liquid separation equipment are centrifugal separation, press filtration, vacuum filtration, etc., but there are generally disadvantages such as inability to work continuously, low efficiency, manual assistance, and incomplete separation. "Fixed Chamber Horizontal Belt Vacuum Filter and Its Development Status" [Nonferrous Metallurgy, 2000 (4): 41~44] announced the DU type horizontal belt vacuum filter, which consists of rubber drainage belt, vacuum box, driving roller, from It is composed of moving roller, feeding device, washing devi...

Problems solved by technology

[0002] At present, the main methods used in solid-liquid separation equipment are centrifugal separation, press filtration, vacuum filtration, etc., but there are generally disadvantages such as inability to work continuously, low efficiency, manual assistance, and incomplete separation.

"Fixed Chamber Horizontal Belt Vacuum Filter and Its Development Status" [Nonferrous Metallurgy, 2000 (4): 41~44] announced the DU type horizontal belt vacuum filter, which consists of rubber drainage belt, vacuum box, driving roller, from It is composed of moving roller, feeding device, washing device, unloading device, filter cloth, filter cloth tape cleaning device, filter cloth tensioning device, filter cloth deviation adjustment device, driving device, frame and other components, and its working process is slurry The feeding device is evenly distributed to the moving filter medium (filter cloth), and the slurry is separated from the solid and liquid under the combined action of gravity and vacuum. The equipment has a narrow application field due to the rubber drainage belt and has high requirements for vacuum. Moreover, the cost of the rubber drainage belt is high, and the separated solid product needs further processing

Chinese patent ZL200610050021X discloses a vacuum belt filter dehydrator, based on the traditional rubber belt vacuum filter, the vacuum chamber is improved to reduce energy consumption; Chinese patent ZL2008201074981 discloses a vacuum belt filter The machine has added a conveying mesh bag, and a filter cloth is arranged above the conveying mesh bag, but it still has not overcome the shortcomings of narrow applicable field, high cost, and further processing of the separated solid product.
