The invention discloses an airflow type atomization feeding spray dryer which comprises a support, a barrel and an airflow type atomizer. Two acoustic wave dust removers are mounted on the side wall of the barrel. The airflow type atomizer comprises a shell. An air inlet pipe is arranged on the side wall of the shell. The airflow type atomizer comprises a feed liquid inlet pipe. The feed liquid inlet pipe penetrates the top of the shell to be inserted in the shell. A plurality of branch pipes are continuously spirally distributed in the feed liquid inlet pipe from the top to the bottom in a clockwise or anticlockwise manner. A baffle is continuously spirally distributed in a cavity from the top to the bottom of the shell in a clockwise or anticlockwise manner, wherein the cavity is formed by the inner wall of the shell and the outer wall of the feed liquid inlet pipe. The effect of continuous dust removing can be achieved through the acoustic wave dust removers; through the adoption of disturbance of high-frequency acoustic waves of the acoustic wave dust removers and the mechanical stirring function, the heat transfer coefficient of dry air and feed liquid is increased easily, and drying efficiency is improved; and atomization treatment on powder high in viscosity or large in grain size is achieved through the airflow type atomizer.
Description
Technical field
The present invention relates to a kind of pre-mixing agent manufacturing and processing equipment, be specifically related to a kind of air-blast atomization feed spray exsiccator.
Background technology
Pre-mixing agent refers to the homogeneous mixture of one or more micro constitutents and diluent or carrier composition.By one or more medicines and substrate be uniformly mixed for making an addition to feedstuff, for feedstuff medicine interpolation pre-mixing agent.Carrier refers to accept and the raised material of carrying powder active ingredient, and trace mineral supplement not only can be played diluting effect by it, moreover it is possible to improves the mobility of additive, makes additive be easier to be distributed in feedstuff.Powdery pre-mixing agent for the easy moisture absorption needed to be dried process before carrying out weighing, packing, and spray dryer can be used sufficiently to be dried.Spray dryer is that a kind of having concurrently is dried and the device of pelletize function, and its operation principle is that clean air passes through heating, enters the air distributor at spray dryer top, and hot-air is evenly into hothouse.Feed liquid, through the nebulizer of transport pump to tower body top, sprays into tiny vaporific liquid pearl, and it is with hot-air and flows to contact and is dried rapidly as finished product.Finished product is exported with in follow-up cyclone separator by bottom exsiccator continuously, and waste gas is emptied by air-introduced machine.
Due to the character particularity of powdery pre-mixing agent, existing spray drying technology is susceptible to wall sticking phenomenon in process of production.Material glues wall and operates not only bad for collecting, and as time went on, the material of heat sensitivity is apt to deteriorate, becomes defective material.And, adhesion time is long, needs to shut down special cleaning exsiccator inwall, and process is numerous and diverse.
Summary of the invention
The technical problem to be solved is that powdery pre-mixing agent easily occurs viscous wall in spray-drying process, it is therefore intended that provide a kind of air-blast atomization feed spray exsiccator, it is achieved remove exsiccator inwall bur continuously, keep the state of high-efficiency cleaning.
The present invention is achieved through the following technical solutions:
A kind of air-blast atomization feed spray exsiccator, including support, cylinder and pneumatic atomizer, described cylinder is fixed on support, the bottom of cylinder is provided with discharging opening, equipped with two sound wave clear powder devices on the sidewall of described cylinder, described pneumatic atomizer includes housing, the housing sidewall near top is provided with air inlet pipe, the bottom of housing is provided with atomisation outlet, pneumatic atomizer also includes feed liquid inlet pipe, feed liquid inlet pipe runs through the top of housing, insert enclosure interior, and the outlet ends of feed liquid inlet pipe is positioned at housing, it is placed with at least two arms in feed liquid inlet pipe by top to bottom continuous helical in the way of clockwise or counterclockwise, in the cavity that inner walls and feed liquid inlet pipe outer wall are constituted, it is placed with baffle plate with counterclockwise or clockwise mode continuous helical by case top to bottom.
When using spray dryer to be dried powder, higher particularly with viscosity or that granularity is bigger powder is difficult to use pressure-type spray day with fog to process, therefore the present invention carries out atomization process by pneumatic atomizer to feed liquid.Feed liquid has feed liquid inlet pipe to be pressed into, and the straight tube arranged by dense helical is with downward spiral by the way of turning clockwise or rotating counterclockwise, so that feed liquid is more dispersed at the feed liquid pipe port of export, and derives with eddy current shape.In the cavity that inwall and the feed liquid inlet pipe outer wall of housing are constituted, by the bottom continuous helical arrangement baffle plate at the top of housing to housing, the gas passage of downward spiral is constituted by inner walls, helical baffle and feed liquid inlet pipe outer wall, and in opposite direction with the direction of counterclockwise or clock-wise fashion, i.e. downward spiral and feed liquid downward spiral of spiral way.Now it is dried gas to be pressed into by air inlet pipe, it is dried gas and forms air whirl by helical duct downward spiral, and at the end outlet of feed liquid inlet pipe with vortex feed liquid generation strong collision, mix and then form spraying, enter in cylinder finally by atomisation outlet and carry out contact drying more fully.By installing sound wave clear powder device on the sidewall of cylinder, sound wave clear powder device is started in exsiccator dry run, in barrel space, utilize the concussion effect repeatedly of low-frequency sound wave, put on dust, with circulation change such as stretching extruding, when reaching certain cyclic strain number of times, the bond strength of adhesion dust is destroyed because of repeated strain.Thus can constantly the powder sticked on cylinder inboard wall be removed, it is achieved cylinder inboard wall keeps permanent cleaning, has higher efficiency of dust collection.
Described sound wave clear powder device uses high frequency sound wave, and two sound wave clear powder devices are the most staggered and are distributed in the both sides that relative cylinder axle center is symmetrical.
The high frequency sound wave of sound wave clear powder device has higher mechanical agitation effect relative to low-frequency sound wave to dry gas and feed liquid, and two sound wave clear powder device both sides that are the most staggered and that be distributed in relative cylinder axle center symmetrical can be increased sound wave clear powder device to dry gas and the perturbation action of feed liquid, thus be conducive to increasing both convective heat-transfer coefficients, drying efficiency can be improved greatly.
The inwall of described housing is provided with electric heating layer.
By arranging electric heating layer on the inwall of pneumatic atomizer housing, the dry gas that air inlet pipe imports can be heated to uniform temperature, from without arranging gas-heating apparatus specially, simplify structure.Meanwhile, the more convenient utility steam of electric heating layer is set as dry gas, advantageously reduces cost.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, one air-blast atomization feed spray exsiccator of the present invention, uses sound wave clear powder device, can realize the most clear dust effect, make exsiccator inwall often keep clean state, also do not have powder and adhere to the phenomenon that even high temperature is charred, ensured product quality；
2, one air-blast atomization feed spray exsiccator of the present invention, by disturbance and the mechanical agitation effect of the high frequency sound wave of sound wave clear powder device, is conducive to improving dry gas and the heat transfer coefficient of feed liquid, greatly improves drying efficiency；
3, one air-blast atomization feed spray exsiccator of the present invention, the atomization that can be realized higher to viscosity or that granularity is bigger powder by pneumatic atomizer is processed, and improves its drying efficiency, reduces cost.
