Abstract
The present invention devises a kind of use for laboratory ultrasonic assistant resistance drying baker, structure includes casing, resistance heating wire, material tray, horn, ultrasonic transducer and ultrasonic signal generator, during work, ultrasonic activation passes to the powder body to be dried in material tray or block material by horn and the material tray of integration, making powder body or block material be in supersonic vibration state in dry run, the liquid in material accelerates diffusion, quickly volatilization and is dried.The present invention can shorten the drying time of powder body and lump material, improves drying efficiency and quality, reduces the reunion of powder material, is particularly suitable for being dried of a small amount of powder body of laboratory or block material.
Description
Technical field
The present invention relates to a kind of resistance drying baker, particularly relate to a kind of use for laboratory and done by ultrasonic activation auxiliary resistance
Dry powder body and the drying baker of block material.
Background technology
Resistance drying baker use Resistant heating, due to equipment be simple and convenient to operate, with low cost, be widely used in reality
Being dried of powder body and block material during testing, but resistance drying baker exists and is dried slow, uneven drying, to dry powder body
The defects such as damage are had with pattern and the character of block material.Ultrasound wave is as a kind of form of energy, the cavitation produced when propagating
Effect, mechanical effect and heat effect can be with the heat and mass transfer processes of fortification substance, the transition process of liquid in acceleration material, the most extensively
General it is applied to the fields such as cleaning, dispersion, emulsifying.Ultrasound wave by vibration at high speed heat and mass transfer enhancement, has quickening in being dried
In rate of drying and reduction material, the effect of residual liquid, can shorten the drying time of material, and can reduce powder material
Reunite, it is ensured that be dried powder body and the character of block material.
Although the patent of invention Shen that the most existing ultrasound wave drying equipment, such as application publication number are CN 104941830 A
Please disclose a kind of ultrasonic activation heat drying apparatus, but the heating of its coated substrates being mainly used in flat faced display is done
Dry, structure is more complicated, is not suitable for being dried of a small amount of powder body of laboratory and block material；Authorization Notice No. is CN
The patent of invention of 101586905 B discloses a kind of ultrasonic hot air combined dryer, its be applicable to large batch of food and
Medicine is dried, and is not suitable for being dried of a small amount of powder body of laboratory and block material.The present invention has and the ultrasound wave announced
Firing equipment or the different structure of ancillary heating equipment, and being dried of powder body and block material be applicable to laboratory.
Summary of the invention
The present invention is directed to existing use for laboratory resistance drying baker exist be dried slow, uneven drying, to dry powder body and
Pattern and the character of block material have the defects such as damage, devise a kind of use for laboratory ultrasonic assistant resistance drying baker, pass through
Ultrasonic activation improves the resistance of powder body and lump material and is dried.Technical scheme is as follows:
A kind of use for laboratory ultrasonic assistant resistance drying baker, including casing, resistance heating wire, material tray, horn,
Ultrasonic transducer and ultrasonic signal generator, it is characterised in that: one side that resistance heating wire is positioned at around box house or
Multiaspect；One end of horn is connected with the bottom of material tray or side, is positioned at box house；Horn passes case by aperture
Body, aperture is positioned at bottom or the side of casing, and the other end of horn is connected with the ultrasonic transducer being positioned at outside casing.
Described use for laboratory ultrasonic assistant resistance drying baker, it is characterised in that: material tray, the material of horn are
Rustless steel, material tray welds together with one end of horn, and the other end of horn and ultrasonic transducer are welded on one
Rise.
Described use for laboratory ultrasonic assistant resistance drying baker, it is characterised in that: the operating temperature range of drying baker is
Room temperature～300 DEG C, dry atmosphere includes that nature resistance is dried, air blast resistance is dried, vacuum resistance is dried or protective atmosphere resistance
It is dried.
Described use for laboratory ultrasonic assistant resistance drying baker, it is characterised in that: the power of ultrasonic activation and loading
Time is controlled by ultrasonic signal generator, ultrasonic transducer produce ultrasonic activation by integration horn and
Material tray passes to the powder body to be dried in material tray or block material, makes powder body or block material locate in dry run
In supersonic vibration state, the liquid in material accelerates diffusion, quickly volatilization and is dried.
The present invention has a following beneficial effect:
(1) ultrasound wave makes material high-speed vibrate, and improves the heat transfer in dry run and mass-transfer efficiency, shortens drying time.
(2) liquid distribution in ultrasonic activation makes material is uniform, makes the homogeneous temperature of material each several part in dry run,
The drying mark of suppression material.
(3) powder material is in supersonic vibration state in dry run, it is to avoid powder body in dry run due to liquid
The reunion that body volatilization causes, makes dried powder material present preferable dispersity.
(4) this equipment is particularly well-suited to need not a small amount of powder body of laboratory of movement or block material in dry run
It is dried.
