The gentle base drilling fluid three major types of base drilling fluid, oil base drilling fluid.
In drilling process, drilling fluid enters to bottom by drilling rod, caused useless in after completing its effect with drilling well
Slag is discharged together, and due to drilling fluid, not only price is high but also meeting welding, so should be reclaimed to drilling fluid, solid controlling
System is exactly for reclaiming drilling fluid.Solid controlling system is also called drilling-fluid circulation system and drilling fluid cleaning system.Solid controlling system
System mainly includes the solid control equipments such as drilling fluid vibrating sieve, vacuum degasser, desander, desilter, horizontal spiral centrifuge.These
Solid control equipment realizes purification and the recycling to drilling fluid by layering just as a series of different sieve of sizes, function.
Drilling fluid vibrating sieve is the one-level solid control equipment for circulation of drilling fluid, cleaning system, has oscillation intensity height, sieve
The features such as facet product is big.Drilling fluid vibrating sieve is mainly used in removing bore meal particles larger in drilling fluid, safeguards the property of drilling fluid
Can be equipment most important in solid controlling system with the treatment effect and service life of the solid control equipment after guarantee.
Because drilling fluid is stressed in fill process and cast to screen cloth, the screen cloth close to charging aperture loses
Sieving actoion, and being not constant between due to pressure, when running into pressure and increasing suddenly, drilling fluid charging rate is accelerated,
From the distant of charging aperture ejection, sieving actoion, drilling fluid falling on screen cloth are lost not only near to the screen cloth of charging aperture
One section of screen cloth between point and charging aperture can all lose sieving actoion, due to jetted larger distance, the sieving of drilling fluid
Area reduces, and causes the solid phase particles in drilling fluid not to be in time for also separately just have left screen cloth with liquid phase, enabling recovery
Drilling fluid liquid phase loss, not only pollute environment also add drilling cost.
The content of the invention
The technical problems to be solved by the invention are the shortcomings that being directed to traditional splashing prevention device for drilling fluid vibrating screen, it is therefore intended that
The anti-splash device of drilling process mud reclamation device is provided, solves traditional drilling fluid vibrating sieve solid phase particles in screening process
It is not in time for also separately just have left screen cloth with liquid phase, takes away the recyclable liquid phase in part, causes recyclable liquid phase damage in drilling fluid
The problem of mistake.
The present invention is achieved through the following technical solutions：The anti-splash device of drilling process mud reclamation device, including two phases

Portion is fixed on the second sliding block, and block cover is connected between two metal frames, and the block cover is flexible material.In the prior art, pass
The drilling fluid vibrating sieve of system is being provided with anti-splash device at charging aperture, but the effect of this anti-splash device is to avoid drilling well
Liquid from charging aperture enter on screen cloth when to surrounding splash so that the drilling fluid of screen cloth porch along screen cloth during vibrating
Drilling fluid vibrating sieve will not be spilt.In practice, it has been found that because drilling fluid is from charging aperture in fill process after being under pressure
Cast to screen cloth, so the screen cloth between drop point and charging aperture of the drilling fluid on screen cloth can all lose sieving actoion, and
And because pressure is not constant between, with the change of pressure, between drop point and charging aperture of the drilling fluid on screen cloth away from
From can also change, when running into pressure and increasing suddenly, drilling fluid charging rate is accelerated, from the distance that charging aperture sprays compared with
Far so that the screen cloth of major part loses sieving actoion, causes the sieving area of drilling fluid to reduce, and causes part is glutinous to carry
The exit that the solid particle of drilling fluid liquid phase just has moved to screen cloth when not separated with liquid phase also is collected, and causes to bore
The liquid phase loss that can be recycled in well liquid, add the use cost of drilling fluid；Further, since not only wrapped in drilling fluid liquid phase
Containing decentralized medium such as water, the chemical substances such as inorganic agent are further comprises, deals with and adds drilling fluid use cost, if do not located
Reason drains into the external world, can cause environmental pollution.In order to solve the above problems, the invention provides one kind to be installed on drilling fluid vibration

Just it is moved to screened outlet down, it is ensured that drilling fluid will not sputter drilling fluid vibrating sieve, maximumlly remain recyclable
Liquid phase, environment is also protected while the use cost for reducing drilling fluid.
When inlet amount is larger, drilling fluid is larger to the impact of blowout prevention plate, and its bounce-back is also larger, and drilling fluid is more to surrounding
Splash and rebounded to charging aperture, cause charging aperture to damage, and due to closer to the distance, drilling fluid be sprayed on pressure on blowout prevention plate compared with
Greatly, blowout prevention plate is caused to damage using easy for a long time；When inlet amount is smaller, if blowout prevention plate apart from charging aperture farther out, rise
Less than the effect of blowout prevention, in addition can the vibrated effect of arresting portion and the drilling fluid thrown, make the treating capacity of drilling fluid vibrating sieve
Reduce, because distance is remote, blowout prevention plate can not rebound to drilling fluid, and the drilling fluid for making to cast out from charging aperture is on screen cloth

Bounce-back, it is ensured that the utilization rate of screen cloth.
Usual screen cloth is obliquely installed, and is easy to drilling fluid to be moved while Separation by vibration from charging aperture to discharging opening
It is dynamic, the solid phase particles separated and liquid phase finally are collected in discharging opening, but as the increase at angle of inclination, drilling fluid are vibrating
By the horizontal range increase of screen cloth throwing under effect, when run into vibration it is slightly larger compared with strong and screen slope angle when, on screen cloth
Drilling fluid will be cast to discharge outlet in experience collision rift several times, cause the waste of drilling fluid.It is above-mentioned in order to solve
Problem, the present apparatus are provided with two metal frames, and one of metal frame is connected to side of the splash-back away from charging aperture, another
Metal frame is fixed on the second sliding block, and the second sliding block matches with guide rail, and block cover is provided between two metal frames, and block cover is soft
