Abstract

The utility model relates to a dual-split-level structure sieve box device of a vibration sieve, which is first-class equipment for carrying out solid-phase control for drilling fluid in an oilfield and overcomes the defects existing in other arts. The sieve box device is formed by connecting a sieve box, a screening system with an adjustment support system, and the screening structure is dividedinto a first-class screening structure, a second-class screening structure, a third-class screening structure and a fourth-class screening structure which are scattered into four upper, middle and lower layers in sequence. The sieve box is connected with a base by the adjustment support system, and the incline angle of the sieve box can be regulated in the range of -1 to +5 degrees. The orderly split-level screening system can increase the conventional separation ability for distributing and processing the drilling fluid in a limited space, effectively increases the area and volume of a fluidpool in the range of width and length, reduces the accumulated sand phenomenon, enlarges the overflow area under the condition of same length and width, effectively enlarges the handling capacity of large drilling fluid and improves work efficiency.

Description

A kind of pair of staggered floor construction vibratory sieve screen box device

One, technical field:

The utility model relates to technology, especially a kind of pair of staggered floor construction vibratory sieve screen box device of a kind of oil drilling liquid-solid phase control first order equipment.

Two, background technology:

Various types of vibratory sieve has been equipped with and has been used in effective separation process of oil well drilling process and drilling fluid and harmful solid phase, but common shortcoming is: the vibratory sieve sieve nest is little to the drilling fluid treating capacity, and dispersibility is not strong, and treatment effect is not good enough, easily stick with paste sieve, cause waste.

Three, summary of the invention:

It is constant that the purpose of this utility model provides a kind of screen box length, increases a kind of pair of staggered floor construction vibratory sieve screen box device of drilling fluid treating capacity, and he has overcome the shortcoming that other technologies exist.The purpose of this utility model is achieved in that it is to be formed by connecting by screen box, screening system, adjustment support system.Screen box is connected by adjusting support system with base, and the screen box tilt adjustable saves in-1～+ 5 degree scope; Screening system is formed by screen box, screening structure, aqueduct, screen cloth support and connection straggly successively; The screening structure is divided into the screening structure first order, the screening structure second level, the screening structure third level and the screening structure fourth stage, and is four layers straggly successively of upper, middle and lower.The screening structure first order is connected with aqueduct, sieve the structure second level and sieve the structure first order and be connected, and vertical range has drop, and horizontal range is straggly overlapping; The screening structure third level is connected with the screening structure second level, and vertical range has drop, the compact connection of horizontal range; The screening structure fourth stage supports with the screening structure third level with screen cloth and is connected, and with the screening structure third level drop is arranged on vertical range, and horizontal range is straggly overlapping; Make screen box under equal length, increase the inflow-rate of water turbine of drilling fluid, after being adjusted to certain inclination angle, vibratory sieve forms liquid pool respectively on screen box both sides and screen box length direction, can more effectively increase the contact area of drilling fluid and the decentralization of raising drilling fluid, thereby improves the treating capacity of drilling fluid.

The beneficial effects of the utility model are, under identical screen box length, effectively increase the oil field drilling fluid high throughput vibratory sieve of sieve nest inflow-rate of water turbine, effective dispersion treatment drilling fluid, be applicable to all kinds of oilfield treatments drilling fluids, especially the situation that the device processes amount is had requirement, can enlarge processing area as far as possible, improve processing speed, save cost.

Four, description of drawings:

Fig. 1 is an a kind of pair of staggered floor construction vibratory sieve screen box apparatus structure schematic diagram, 1, the screening structure first order 2, the screening structure second level 3, the screening structure third level 4, the screening structure fourth stage 5, aqueduct 6, screen cloth support 7, screen box 8, screening system 9, adjust support system

Fig. 2 is the screening system schematic diagram of a kind of pair of staggered floor construction vibratory sieve screen box device, among the figure 1, the screening structure first order 2, the screening structure second level 3, the screening structure third level 4, the screening structure fourth stage

Five, the specific embodiment:

In Fig. 1 and Fig. 2, screen box 7 is connected by adjusting support system with base, and screen box 7 tilt adjustable save in-1～+ 5 degree scope; Screening system 8 is to be supported 6 and be formed by connecting by screen box 7, the screening structure first order 1, the screening structure second level 2, the screening structure third level 3 and the screening structure fourth stage 4, aqueduct 5, screen cloth, the screening structure is divided into the screening structure first order 1, the screening structure second level 2, the screening structure third level 3 and the screening structure fourth stage 4, and is four layers straggly successively of upper, middle and lower.The screening structure first order 1 is connected with aqueduct 5, sieve the structure second level 2 and sieve the structure first order 1 and be connected, and vertical range has drop, and horizontal range has straggly overlapping; The screening structure third level 3 is connected with the screening structure second level 2, and vertical range has drop, the compact connection of horizontal range; The screening structure fourth stage 4 is connected with the screening structure third level 3 with screen cloth support 6, and with the screening structure third level 3 drop is arranged on vertical range, and horizontal range is straggly overlapping; Drilling fluid is at first handled through the screening structure first order 1 after entering screening system, enters the screening structure second level 2 and the third level 3 processing again, enters the screening structure fourth stage 4 at last and handles.
