Traditional drilling fluid vibrating sieve is during the liquid phase and solid phase particles of screening drilling fluid, part drilling fluid remains in the sieve aperture on screen cloth, cause the liquid phase in drilling fluid can not flow in screen box, cause running pulp, lose expendable-limited-recoverable drilling fluid liquid phase, not only pollute environment and also add drilling cost.It addition, the drilling fluid remained in sieve aperture not only reduces the treating capacity of drilling fluid vibrating sieve, also result in the load on screen cloth and increase, damage screen cloth.
Summary of the invention
The technical problem to be solved is the shortcoming for tradition drilling fluid vibrating sieve, purpose is to provide drilling fluid regenerating unit, solves traditional drilling fluid vibrating sieve drilling fluid in screening process and causes the problem that in drilling fluid, callable liquid phase runs off, drilling fluid vibrating sieve treating capacity reduces and is easily damaged screen cloth in easily remaining in the sieve aperture on screen cloth.
nullThe present invention is achieved through the following technical solutions: drilling fluid regenerating unit，Including screen box，Vibrating motor it is provided with below screen box，Gripper shoe it is provided with outside screen box，Connect below gripper shoe and have tensioning spring，Tensioning spring lower end connects pillar，Screen box one end be provided above charging aperture，The other end is provided with solid phase discharging opening，Screen frame it is provided with in screen box，Screen cloth it is provided with in screen frame，Screen cloth is gradually lowered to the direction of solid phase discharging opening along charging aperture with the distance of horizontal plane，The liquid phase feed box connected with screen box it is provided with below solid phase discharging opening，Liquid phase feed box is positioned at below screen cloth，Liquid phase discharging opening it is provided with bottom liquid phase feed box，Liquid phase feed box side connects exhaust column，Exhaust column connects air exhauster，Also include blowout prevention plate，Blowout prevention plate is just to charging aperture，The side of blowout prevention plate is vertically connected with splash-back，Splash-back is fixed on screen box，Blowout prevention plate top is provided with top board，Top board is arranged above water inlet pipe，Water inlet pipe top connects water pump，Top board is run through to below top board and just to blowout prevention plate in water inlet pipe bottom，Splash-back has block cover away from connecting on the side of charging aperture，Block cover extends along screen box to solid phase discharging opening.In prior art, traditional drilling fluid vibrating sieve is during the liquid phase and solid phase particles of screening drilling fluid, part drilling fluid remains in the sieve aperture on screen cloth, cause the liquid phase in drilling fluid can not flow in screen box, cause running pulp, lose expendable-limited-recoverable drilling fluid liquid phase, and remain in the drilling fluid in sieve aperture and not only reduce the treating capacity of drilling fluid vibrating sieve, also result in the load on screen cloth to increase, damage screen cloth.In order to solve the problems referred to above, the invention provides a kind of drilling fluid vibrating sieve with exhausting system.This device is provided with liquid phase feed box below solid phase discharging opening, is positioned at the space below screen cloth in liquid phase feed box connection screen box, and the side of liquid phase feed box is connected by exhaust column air exhauster.When using this device, first turn on vibrating motor and air exhauster, until drilling fluid after charging aperture enters to screen cloth, the effect of vibration of drilling fluid motor vibrated, the normal direction along screen cloth is thrown, and then falls and impinges upon on screen cloth, liquid phase in drilling fluid enters in screen box by the sieve aperture on screen cloth, solid phase particles continues to continue vibrated effect above screen cloth and throws and impact screen, when impact screen separates the liquid phase carried, while moving to solid phase discharging opening.Air exhauster makes air-flow enter to below screen cloth by sieve aperture above screen cloth, enters liquid phase feed box afterwards, drains into air eventually through air exhauster.Air-flow is when by sieve aperture, negative pressure is formed between the upper and lower of screen cloth, make drilling fluid after impact screen, the liquid phase departing from solid phase particles is easier to enter to below screen cloth, do not result in blocking screen cloth, not only increase the drilling fluid vibrating sieve treating capacity to drilling fluid, also reduce the load of screen cloth, extend the service life of screen cloth；It addition, air-flow also makes drilling fluid when occurring to clash into screen cloth, the impulse force of shock strengthens so that solid phase particles is easier to separate with liquid phase, improves the yield of liquid phase capable of circulation；Meanwhile, the liquid phase that air-flow can also accelerate in screen box moves to liquid phase feed box, accelerates recovery speed.
Traditional drilling fluid vibrating sieve is being provided with anti-splash device at charging aperture, but the effect of this anti-splash device is to avoid drilling fluid to splash to surrounding when charging aperture enters to screen cloth so that the drilling fluid of screen cloth porch will not spill drilling fluid vibrating sieve during vibrating along screen cloth normal direction.In practice, it has been found that after being affected by pressure due to drilling fluid when fill process from charging aperture impelling to screen cloth, so the screen cloth between drop point and charging aperture that drilling fluid is on screen cloth all can lose sieving actoion.The discharge pressure of drilling fluid is not constant between, change along with pressure, distance between drilling fluid drop point and charging aperture on screen cloth also can change, when running into pressure and increasing suddenly, drilling fluid charging rate is accelerated, from charging aperture ejection distant, the screen cloth making major part all loses sieving actoion, the area that sieves causing drilling fluid reduces, the exit causing part tape-supported adhesive to have the solid particle of drilling fluid liquid phase just to have moved to screen cloth the most not with liquid phase the most separately time is collected, the liquid phase loss that can be recycled in drilling fluid, add the use cost of drilling fluid.In order to solve the problems referred to above, this device is being provided with blowout prevention plate, and the plate face of blowout prevention plate just to charging aperture, connects the upper edge having splash-back, splash-back to be fixed on screen box in the side of blowout prevention plate, blowout prevention plate is arranged above top board, is mutually perpendicular to two-by-two between top board, splash-back, blowout prevention plate.When drilling fluid is under pressure and sprays from charging aperture, drilling fluid impinges upon on blowout prevention plate, in part drilling fluid bounce-back to the screen cloth below charging aperture；Part drilling fluid sticks on blowout prevention plate, by the screen cloth below landing after action of gravity and effect of vibration to blowout prevention plate；Part drilling fluid splashes to surrounding after shock, and inside splash-back and the bottom of top board is it can be avoided that drilling fluid sputters drilling fluid vibrating sieve everywhere after blowout prevention plate and loses clashing into.Pass through said apparatus; not only ensure that drilling fluid can be through bigger screen area; improve the utilization rate of screen cloth; solid particle is avoided just not move to screened outlet with in the case of liquid phase separation; also assures that drilling fluid will not sputter drilling fluid vibrating sieve; remain liquid phase capable of circulation substantially, while reducing the use cost of drilling fluid, also protect environment.
The most also find, in use for some time, on blowout prevention plate, splash-back and screen cloth, meeting adhesion section drilling fluid, does not only result in and have lost part drilling fluid, also increase the weight of the load on screen cloth, the sieve aperture blocked on part screen cloth, cause the separating effect of drilling fluid vibrating sieve to reduce.In order to solve the problems referred to above, this device is provided with some water inlet pipes on top board, and top board is run through and just to blowout prevention plate in water inlet pipe bottom.After drilling fluid vibrating sieve uses a period of time, opening water pump, water pump is by hydraulic pressure to water inlet pipe, current splash after being sprayed on blowout prevention plate and wash away inside splash-back and bottom top board, current drop down onto on screen cloth afterwards, are diluted the drilling fluid on screen cloth, and the drilling fluid after dilution falls into screen box.By said mechanism, not only alleviating the load of screen cloth, extend the service life of screen cloth, the drilling fluid by residual the most as much as possible is mixed in the drilling fluid of circulation after diluting, and reduces drilling fluid use cost.
Owing to screen cloth is obliquely installed, increase along with screen slope angle, drilling fluid is under the effect of vibration by screen cloth normal direction, the vertically distance being cast is the highest, the horizontal range that drilling fluid moves is the most remote, when running into compared with strong and when screen slope angle is slightly larger, the drilling fluid on screen cloth will be cast to solid phase discharge outlet only experiencing collision rift several times, causes the waste of drilling fluid.In order to solve the problems referred to above, this device is provided with block cover, and block cover one end is connected on splash-back and blowout prevention plate, and block cover extends near solid phase discharging opening along edge on screen box, and block cover is positioned at directly over screen cloth.When vibrated effect is tossed on screen cloth for drilling fluid, run into the rebound effect of block cover, the gravity being subject in conjunction with drilling fluid self, again drop down onto on screen cloth and separate, add drilling fluid shock number of times on screen cloth, promote the solid phase particles in drilling fluid and liquid phase separation further, improve the separation efficiency of screen cloth；It addition, block cover is also avoided that drilling fluid will not spatter outside vibrosieve during vibrated effect is cast, it is possible to be recovered to more drilling fluid.
