Description
Technical field：
The present invention relates to soil's water content Quick testing instrument and assay method.
Background technology：
" soil " is meant that broad sense in current national standard testing regulations, refers to particulate used in civil engineering construction
Soil, cohesive soil, gravel soil, gravelly soil etc..The experiment of regulatory requirements soil's water content has three kinds of methods：Oven drying method, alcohol combustion method
And hydrometer method, oven drying method is to keep 105 ~ 110 DEG C other energy baking ovens, representative particulate using Electric heat oven or temperature
15 ~ 30g of soil sample, drying time must not be less than 8h, and stickiness local product dries 8 ~ 10h, for most of soil generally 16 ~ 24h of drying,
Alcohol combustion method needs to carry out three circulations with alcohol burn and cooling, and 1 part of sampling test needs three alcohol burns, completes examination
30 ~ 40min of the time of taking around is tested, required time is longer, and feedback data is slow, seriously restricts construction speed.
The content of the invention：
It is an object of the invention to provide soil's water content Quick testing instrument and assay method.
Above-mentioned purpose is realized by following technical scheme：
A kind of soil's water content Quick testing instrument, its composition includes：Circuit integrating device, described circuit integrating device respectively with
Actuation means, air draft dehydrating unit, drying unit, display device, printing equipment by connection, described drying unit with
Described air draft dehydrating unit is bolted to connection.
Described soil's water content Quick testing instrument, described drying unit includes microwave drying cavity, described microwave
The side of drying cavity is provided with microwave generator, and described microwave generator and transformer are by connection, and described is micro-
One group of multidigit weighing device is installed, described weighing device passes through connection, institute with weighing sensor in ripple drying cavity body
The circuit integrating device stated passes through connection with described weighing sensor respectively.
A kind of assay method of soil's water content Quick testing instrument, this method comprises the following steps：Sample is placed on baking
On weighing device in equipment for drying, check weighing numerical value is conducted and is stored in circuit integrating device by circuit, synchronous to pass through circuit
Show on the display apparatus, manipulating instrument by actuation means brings into operation, automatic drying is dry after sample is oven-dried dehydration
After constant mass, instrument reads sample dry mass numerical value automatically, goes out moisture content by circuit integrating device logical calculated, and show
On the display apparatus, after dry mass is constant it is automatic close drying unit, related data set by display device simultaneous display, it is necessary to
Printed when being exported to screen display data-printing.
Beneficial effect：
1. the present invention relates to soil's water content Quick testing instrument and assay method, drying unit passes through bolt with air draft dehydrating unit
Connection, it is ensured that moisture is effectively discharged, while promoting hydrofuge, reduces sample temperature, basic guarantee sample maximum heating temperature exists
105 ~ 110 DEG C, meet government test code rated condition.
The actuation means of the present invention mainly carry out overall manipulation to instrument, are grasped, made using interactive touch screen display structure
More convenient, intelligence degree is high.
The display device of the present invention can show that printing equipment uses minitype thermal printer in time to the data of measurement,
Printing is more rapidly, it is possible to achieve human-computer interaction.
The present invention, which completes experimental period, only needs 4 ~ 6min, realizes that effect improves 100 times.Existing testing regulations moisture content is surveyed
The supplement of method for testing, is also the blank for filling up soil's water content test apparatus species.
The present invention shortens the cycle in soil's water content experiment, and microwave drying method is shortened to from electric furnace oven drying method test period 8h
4-6min, improve about 100 times of efficiency, test apparatus is light, removable, realizes that Site Detection directly gives data result,
Realize monommechanization, intellectuality, it is possible to achieve inanimate matter soil's water content is dried, weighed automatically, logical calculated, digital display, printed on
One, simple and fast.
The present invention, which is used, is better than electric dry oven oven drying method, and energy-saving 90%, it is efficiently convenient, it is easy to promote.
Moisture discharge speed of the present invention is fast, and inside remains drying regime, and drying rate is fast, and accuracy rate is high, this
The drying cohesive soil sample velocities of invention are 8 ~ 10 times of alcohol combustion method, 100 times of electric furnace Oven Method, effectively raise examination
Efficiency is tested, can realize that field, job site etc. are tested, not limited by place, improve test efficiency, realize direct guiding construction
Production, plant equipment, personnel are not produced and is delayed work phenomenon, accelerating construction progress, reduce direct cost expenditure.
The measure moisture content error of the present invention is not more than 2%, complies fully with existing national regulation requirement.
Power reguirements of the present invention can exchange AC220 or direct current DC24 or DC12, simply, convenient.
