Description

Discontinuous landwaste Quick air drier
Technical field
The present invention relates to geological logging debris dry technologies, specifically discontinuous landwaste Quick air drier.
Background technique
During oil-gas exploration, drilling fluid refers to fluid media (medium) used in drilling process.Drilling fluid can be liquid or Gas, therefore, drilling fluid should definitely be referred to as drilling fluid.In drilling process, the circulation flushing medium used in pit shaft, again Claim drilling fluid.Drilling fluid can be divided into clear water, mud, free clay phase flushing liquor, emulsion, foam and compression by constituent Air etc..Clear water is to be not necessarily to processing using earliest drilling fluid, easy to use, suitable for complete rock stratum and the ground having abundant water resources Area.Mud is widely used drilling fluid, is primarily adapted for use in the wells such as loose, cranny development, easy collapsing and breaking, water-swellable peeling Wall unstable formation.The main function of drilling fluid is: (1) cleaning shaft bottom, cutting carring;(2) cooling and lubrication drill bit and drill string; (3) rock of borehole lateral pressure is balanced;(4) (control) strata pressure is balanced;(5) suspension landwaste and heavy weight additive;(6) it can sink on ground Except sand and landwaste;(7) hydraulic power is effectively transmitted;(8) the part gravity of drilling rod and casing is born;(9) drilled strata is provided Great mass of data;(10) hydraulic fracture rock etc..
Geological logging is one of important function work of oil-gas exploration, and the work of geological logging is be unable to do without to rock landwaste Observation and analysis, this is also the important foundation for carrying out formation evaluation and oil and gas resource evaluation.It is returned to from underground through drilling fluid carrying The landwaste on ground all adhere to drilling fluid it is dirty object, to carry out observation analysis to landwaste just must clean the dirt of attachment with clear water Completely, to restore subsurface rock true qualities, so, landwaste cleaning becomes an important process at geological logging scene.Landwaste cleaning After enter next step process i.e. drying, the storage and analysis of landwaste need dry landwaste condition, so, it is dry to become one Important process process.Currently, the dry mode of landwaste substantially have it is following several: natural drying air-dries, micro-wave oven is dry and roasting Case baking, still, these types of drying mode are improved with the degree of automation of Efficient Exploration rapid drilling, have not caught up with new probing The requirement of technique.
In site operation, geological logging has entered drying program after having cleaned landwaste.There are many modes of dry landwaste, It is air-dried including natural drying, micro-wave oven (light-wave cooker) is dry and electric oven toasts three kinds of important drying modes.But this Several drying modes are all limited in certain specific environment.Natural air drying sunning needs dry atmospheric environment, air Humidity wants low, temperature wants high, and there is certain wind-force and wind direction to blow;The dry limited amount of the dry landwaste of micro-wave oven is done Dry speed is slow, does not catch up with the needs of fast drilling, meanwhile, micro-wave oven is dry to need more artificial controls, otherwise can burned rock Bits influence subsequent analysis;Oven cooking cycle has been prohibited in most construction requirements because the landwaste after oven cooking cycle its primitively Matter state is destroyed, and affects true analysis and judgement.These types of landwaste drying mode has been difficult to adapt to scientific and efficient show Field working stamndard requirement, affects construction quality, occupies man power and material, be summed up, there are asking for the following aspects Topic:
1. occupying labour, cost of labor increases;
2. environmental condition is limited, the natural drying of landwaste air-dries limited;
3. micro-wave oven toasts limited amount, slow drying speed, the analysis requirement of landwaste in fast drilling can not be adapted to;
4. oven cooking cycle speed is slow, while also having destruction to the reset condition of landwaste, applicability is low;
The exhaust gas generated during 5. indoor landwaste is dry can not effective pump drainage, influence the occupational health of operating personnel;
6. landwaste dry mass is low, the landwaste data condition of Efficient Exploration can not be established;
7. manual operation intervention program is more, safety is poor.
So oil-gas exploration scene needs a kind of device for capableing of efficient landwaste drying.
By retrieval, in the dry field of landwaste, only using the devices such as hot-air seasoning or electric roller drying, do not send out The now landwaste drying device similar with the application.
Summary of the invention
The purpose of the present invention is to provide discontinuous landwaste Quick air drier, energy in constructing operation and daily use at the scene It is enough sufficiently to eliminate its above-mentioned a variety of unfavorable factor, the science and standardization of landwaste drying operation are realized, labour has been liberated, is saved Cost of labor has been saved, has ensured the process work fidelity after landwaste is dry.The equipment safety is reliable, facilitates application, automation Degree is high.
In order to achieve the above objectives, present invention employs following technical solution, discontinuous landwaste Quick air drier, including heat Wind drying unit, the hot-air drying unit are air-heater, further include landwaste cup, vibration device, the landwaste cup is placed in vibration On device, cup lid is arranged in landwaste cup upper port, and the landwaste cup outer wall has a grip ring, which is hollow state, grip ring Upper port and lower port are connected to landwaste cup inner cavity, and an air inlet is also opened up in the grip ring, and air inlet passes through hot air pipe Air-heater is connected, the landwaste cup sidewall also opens up a gas outlet.
The vibration device includes bobbing machine, vibration substrate, oscillating plate, and the bobbing machine includes motor, gear drive machine Structure, vibrating wheels, the motor output end connection gear transmission mechanism, gear drive connect the axis of vibrating wheels, vibrating wheels For eccentric wheel, vibrating wheels contact vibration plate lower surface, the motor, gear drive are each attached on vibration substrate, described Spring is set between oscillating plate and vibration substrate, and the oscillating plate upper surface is fixed with cutting ferrule, the landwaste cup bottom setting card Ring, snap ring are fastened in cutting ferrule.
The vibration substrate is fixed on the bracket of lower section by fastening screw.
The bracket side is equipped with saddle, and the air-heater is fixed on saddle.
