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 spray drying for producing pre-mixing agent
Device.
Background technology
Pre-mixing agent refers to the homogeneous mixture of one or more micro constitutents and diluent or carrier composition.By a kind of or many
Kind of medicine and substrate be uniformly mixed for making an addition to feedstuff, for feedstuff medicine interpolation pre-mixing agent.Carrier refers to connect
Being subject to and the raised material of carrying powder active ingredient, trace mineral supplement not only can be played diluting effect by it, moreover it is possible to improves and adds
The mobility of agent, makes additive be easier to be distributed in feedstuff.Powdery pre-mixing agent for the easy moisture absorption weighs, packs carrying out
Need to be dried process before, spray dryer can be used sufficiently to be dried.It is dry that spray dryer is that one has concurrently
With the device of pelletize function, its operation principle is that clean air is through heating, the air distribution at entrance spray dryer top
Device, hot-air is evenly into hothouse.Feed liquid, through the nebulizer of transport pump to tower body top, sprays into tiny vaporific liquid
Pearl, it is with hot-air and flows to contact and is dried rapidly as finished product.Finished product is continuously by bottom exsiccator and follow-up cyclone separator
Middle output, 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 viscous wall in process of production
Phenomenon.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, and purpose exists
In providing a kind of spray dryer for producing pre-mixing agent, it is achieved remove exsiccator inwall bur continuously, keep high-efficient cleaning
Clean state.
The present invention is achieved through the following technical solutions:
A kind of spray dryer for producing pre-mixing agent, including support, cylinder and preheater, described cylinder is fixed on support
On, described preheater is provided with at least two airways, and airway runs through the top of cylinder and UNICOM's preheater and inner barrel, leads
The port of export of trachea is provided with gas distributor, and the top of cylinder is provided with feed pipe, and the port of export of feed pipe is provided with atomizer, cylinder
The bottom of body is provided with discharging opening, and the sidewall of described cylinder is provided with two sound wave clear powder devices, an at least described airway
The port of export near the medial wall of cylinder.
In dry run, dry gas is introduced into preheater and carries out the pre-heat treatment so that the gas derived from preheater
Having uniform temperature, preheated gas is discharged by gas distributor even in the cylinder of exsiccator by airway.With
This simultaneously, feed liquid is imported by feed pipe, and being nebulized by atomizer is contacted with dry gas in drop enters cylinder and reach
The purpose being dried.By installing sound wave clear powder device on the sidewall of cylinder morning, exsiccator dry run starts sound wave clear powder device,
In barrel space, utilize the concussion effect repeatedly of low-frequency sound wave, put on dust, to stretch the circulation change such as extruding, when
When reaching certain cyclic strain number of times, adhere to the bond strength of dust and be destroyed because of repeated strain.Thus can constantly will adhere to
Powder on cylinder inboard wall is removed, it is achieved cylinder inboard wall keeps permanent cleaning.Meanwhile, the dry gas entering exsiccator uses
Many airways are distributed, and the port of export of an at least described airway is near the medial wall of cylinder, and the program makes along interior
The airway high speed air inlet auxiliary sound wave clear powder device dedusting of wall arrangement, improves efficiency of dust collection, ensures that abundant simultaneously
It is dried gas and feed liquid and carries out being fully contacted dry.
Described sound wave clear powder device uses high frequency sound wave, and two sound wave clear powder devices are the most staggered also at the sidewall of cylinder
It is 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 relative to low-frequency sound wave to dry gas and feed liquid and makees
With, and by the most staggered for two sound wave clear powder devices and be distributed in symmetrical both sides, relative cylinder axle center can to increase sound wave clear
Powder device is to dry gas and the perturbation action of feed liquid, thus is conducive to increasing both convective heat-transfer coefficients, can improve dry greatly
Dry efficiency.
The port of export of described feed pipe is provided with distribution plate, and described distribution plate is evenly distributed with at least three atomizer.
By installing distribution plate at feed inlet end, atomizer is evenly spaced on distributing disc, and beneficially feed liquid is with vaporific
Drop is uniformly sprayed in cylinder, contributes to the contact area increasing drop with dry gas, improves heat transfer efficiency.
The present invention compared with prior art, has such advantages as and beneficial effect:
1, a kind of spray dryer for producing pre-mixing agent of the present invention, uses sound wave clear powder device and dry gas purging, can be real
Now continuous clear dust effect, makes exsiccator inwall often keep clean state, does not also have powder and adheres to even high temperature and be charred
Phenomenon, ensured product quality；
2, a kind of spray dryer for producing pre-mixing agent of the present invention, by using the disturbance of the high frequency sound wave of sound wave clear powder device
With mechanical agitation effect, be conducive to improving dry gas and the heat transfer coefficient of feed liquid, greatly improve drying efficiency.
