Description

Rotary flash evaporation dryer

Technical Field

The utility model provides a drier, a spin flash dryer specifically says so.

Background

When the copper oxide is prepared by the traditional wet method, the wet material of the copper oxide needs to be dried and collected, the wet material is directly dried at high temperature by adopting a drying tower in the traditional method, and the inside is difficult to dry when the outside is dried, so that the drying efficiency of the material is influenced; if the internal material is continuously heated and dried, the external heating temperature of the moisture-containing material is too high, so that the external copper oxide is easily heated to generate high-temperature reaction to generate cuprous oxide, and the quality and the purity of the final product are influenced. The existing wet material of copper oxide is dried by a flash evaporation drying tower, although the drying temperature can be well controlled, the problem that drying efficiency is influenced by unbalanced drying is avoided, high-temperature gas is directly heated and fed by air, and other impurities in the air are introduced to influence the drying quality and purity of the copper oxide; contain the direct feeding of wet material simultaneously, be unfavorable for containing the breaing up of wet material in the tower body to high temperature gas is sent into from the side of tower body, and direct lateral impact contains wet material, and there is the hidden danger of long-pending material tower body bottom, and the gaseous direction of blowing of lateral side is unfavorable for high temperature gas's rising production whirl, and the whirl effect is poor, and is great to the flash drying efficiency influence of breaing up containing wet material.

Disclosure of Invention

To the above problem, the utility model provides a compact structure can compromise drying efficiency, quality, ensures that the wet material of cupric oxide does not have the spin flash dryer of rotten drying.

The utility model adopts the technical proposal that: a spin flash dryer characterized in that: including the main tower, lower air inlet pipeline, air cleaner, air damper, the forced draught blower, a heat exchanger, lower feed line, the feeder hopper, the screw rod charging means, cyclone, the sack cleaner, draught fan and muffler, main tower lower part sets up feeding pipeline and lower air inlet pipeline from top to bottom, lower air inlet pipeline outside-in sets gradually air cleaner down, air damper, the forced draught blower, a heat exchanger, lower feed line connects the screw rod charging means of taking the feeder hopper, main tower upper portion connects cyclone upper portion, cyclone bottom sets up the fan of turning off, the cyclone top is through dust removal union coupling sack cleaner, the sack cleaner bottom sets up ejection of compact butterfly valve, the sack cleaner top connects the exhaust pipeline of taking the draught fan in proper order, the muffler.

Further, the screw feeder is a double-screw feeder.

Further, the cyclone separator is a diffusion type cyclone separator.

Further, the bag-type dust collector is a pulse bag-type dust collector.

Further, the heat exchanger is a superheated steam heat exchanger.

Furthermore, a rotating shaft is vertically arranged at the bottom of the main tower, a fan impeller corresponding to the position of the lower feeding pipeline on the upper interface of the main tower is arranged at the upper part of the rotating shaft, a belt wheel or a speed reducer is externally connected to the lower part of the rotating shaft, and the belt wheel or the speed reducer is connected with an electromagnetic speed regulating motor.

Furthermore, the lower parts of the cyclone separator and the bag-type dust collector are both arranged in a funnel shape.

Furthermore, a material waiting device is arranged below the cyclone separator and the bag-type dust collector.

Adopt above-mentioned technical scheme, the beneficial effects of the utility model are that: when high-temperature gas is fed into the lower part of the main tower, the high-temperature gas is firstly filtered by an air filter to prevent other impurities from being introduced along with the air, the hidden danger of deterioration and impurity increase of chemical reaction is avoided, then the air supply quantity is adjusted by an air damper to adapt to the change requirement of the drying treatment quantity of the main tower, the air supply temperature is ensured to reach 150-, The problem of increase air supply load, the moisture material of copper oxide is through the hot-air flash drying back that fan impeller revolves the drifting, send into diffusion cyclone and pulse bag dust remover branch two-stage after the drying and collect dry copper oxide product, finally discharge hot-blast through the draught fan, combine the muffler to reduce air supply noise.

The utility model discloses simple structure, compactness can evenly, high-efficiently contain wet material to the copper oxide and do not have rotten flash drying, compromise drying efficiency, quality, are fit for the use of industrialization wet process production copper oxide.
