Abstract

A separation type spiral sand conveyer, pertaining to the field of oil well fracturing construction device. The utility model comprises a liquid motor, a coupling, sand conveyer shells, a sliding sleeve, sand hopper, a gearing base, an oil cylinder with the left and the right separated, a screw conveyor, a hoist cylinder, an expansion pipe, a fixed base, a rotation axis and a sand outlet. The sand conveyer adopts two sand conveyer shells and a screw conveyor to realize sand feeding of two sand carriers simultaneously and continuously and to meet the technical need of continuous sand feeding of fracturing trucks in construction. The utility model solves the problems that integrated spiral sand conveyers can only serve one sand carrier once in sand feeding, a intermission period occurs when the first sand carrier leaves the sand blender after sand feeding, and then the second sand carrier takes position and continues sand feeding. As a result, the sand containing proportion of the mixed liquid in a mixed tank can not meet the technical requirement of continuous sand feeding in construction because of the intermission of sand feeding so that the quality of oil well fracturing construction is affected terribly. The utility model is extensively used in oil well fracturing construction of oil field sites.

Description

The separation type screw conveyer

A kind of screw conveyer, particularly a kind of separation type screw conveyer belongs to wellfracturing construction operation device field.

In the wellfracturing construction operation in oil field, sand deliverer is a necessaries with the sand feeding blending equipment of sanding vehicle, the sand deliverer of existing employing is the one-piece auger sand deliverer of a sand hopper always continuing to use for many years, but the one-piece auger sand deliverer can only once be fed sand for a sanding vehicle.In the on-the-spot wellfracturing construction operation, after having fed sand, first sanding vehicle leave blending equipment, continue to feed sand to second sanding vehicle back in place, between produced the intermittent time of feeding sand, at this moment, contain the sand ratio in the mixing can in the mixing material, because of sanding vehicle feed sand intermittently the out of reach construction add the technological requirement of sand continuously, have a strong impact on the operation quality of wellfracturing construction.

The purpose of this utility model, be to provide a kind of sand deliverer is designed to about the screw conveyer of two independent sand hoppers, and can about 30 ° of angles rotations, both kept the performance of one-piece auger sand deliverer, again can about separate, fully satisfy the requirement of oil field compression fracture camp site.Can be applicable to that all kinds of blending equipments of the various discharge capacities in domestic oil field, density and sand ratio carry out the pressure break sediment transport, the separation type screw conveyer that can cooperate simultaneously for the uninterrupted continuously sand of feeding of two sanding vehicles with all kinds of not isometric mixing cans.

The utility model is to realize its above-mentioned purpose by following technical solution.

This separation type screw conveyer is by hydraulic motor 1, coupler 2, sand deliverer shell 3, sliding sleeve 4, sand hopper 5, bearing seat 6, about separate oil cylinder 7, auger 8, hoist cylinder 9, telescopic pipe 10, permanent seat 11, S. A. 12, sand export 13 is formed, it is fixed on the blending equipment by permanent seat 11, it is characterized in that: telescopic pipe 10 is welded on the permanent seat 11, sliding sleeve 4 is installed on the permanent seat 11, hydraulic motor 1, coupler 2, sand deliverer shell 3, sand hopper 5, bearing seat 6 assemblings become a whole back and are connected with S. A. 12, and two sand deliverer shells 3 are installed in two sliding sleeves 4, be fixed with an auger 8 by bearing seat 6 in the sand deliverer shell 3, the upper end of sand deliverer shell 3 is shaped on a sand export 13, hoist cylinder 9 two ends are separately fixed on S. A. 12 and the telescopic pipe 10, separate oil cylinder 7 two ends about in the permanent seat 11 to be connected and fixed seat 11 and sliding sleeve 4 respectively.

The utility model has changed existing one-piece auger sand deliverer after first sanding vehicle fed sand, continue to feed sand to second sanding vehicle, produce an intermittent time, the out of reach pressing crack construction adds the problem of the technological requirement of sand continuously, two sand hoppers independently about employing, and can about separate rotation, both kept the performance of one-piece auger sand deliverer, can fully satisfy the requirement of oil field compression fracture camp site simultaneously for the uninterrupted continuously sand of feeding of two sanding vehicles again.

That the utility model will be further described is as follows below in conjunction with accompanying drawing:

Accompanying drawing 1 is the front view of separation type screw conveyer;

Accompanying drawing 2 is the birds-eye view of separation type screw conveyer;

Accompanying drawing 3 is separated into the structural representation of 30 ° of angles for the separation type screw conveyer;

Accompanying drawing 4 is that A is to view;

Accompanying drawing 5 is the B-B view.

The effect of this separation type screw conveyer is: according to the wellfracturing construction operation mixing material is contained the requirement of sand ratiometric, in the blending equipment auger tank, import the sand of some uninterruptedly, and mix with chemical liquid additive, dry powder additive and water, by sand pump the mixed liquor of mixing and stirring is flowed to fracturing truck and finish the wellfracturing construction operation.

This separation type screw conveyer is by hydraulic motor 1, coupler 2, sand deliverer shell 3, sliding sleeve 4, sand hopper 5, bearing seat 6, about separate oil cylinder 7, auger 8, hoist cylinder 9, telescopic pipe 10, permanent seat 11, S. A. 12, sand export 13 is formed, it is fixed on the blending equipment by permanent seat 11, telescopic pipe 10 is welded on the permanent seat 11, sliding sleeve 4 is installed on the permanent seat 11, hydraulic motor 1, coupler 2, sand deliverer shell 3, sand hopper 5, bearing seat 6 is assembled into whole and S. A. 12 links together, and two sand deliverer shells 3 are installed in two sliding sleeves 4, when moving up and down: hoist cylinder 9 two ends are separately fixed on S. A. 12 and the telescopic pipe 10, S. A. 12 is under the telescopic action of hoist cylinder 9, move up and down along telescopic pipe 10, thereby the parts that drive two sand deliverer shells 3 and fit together move up and down, and two sand deliverer shells 3 slide up and down in sliding sleeve 4 respectively simultaneously.During left rotation and right rotation: be installed in the permanent seat 11 about separate oil cylinder 7 two ends and be connected with sliding sleeve 4 with permanent seat 11 respectively, by about separate the flexible of oil cylinder 7 and make sliding sleeve 4 sway on permanent seat 11, thereby drive two sand deliverer shells 3 and the parts that fit together rotate on S. A. 12.

During work, start hoist cylinder 9, sand deliverer shell 3, sand hopper 5 are descended along sliding sleeve 4, when sand hopper 5 will be near ground, separate oil cylinder 7 about startup, make sand deliverer shell 3, sand hopper 5 after S. A. 12 rotates to 30 ° of angles, drop down onto ground.

Hydraulic motor 1 drives auger 8 by coupler 2 and rotates, make sand in the sand hopper 5 along with auger 8 rotates, spiral inner wall along sand deliverer shell 3 rises, in sending into auger tank on the blending equipment from sand export 13, mix with chemical liquid additive, dry powder additive and water, formation necessarily contains sand ratiometric mixing material.Rotating speed by regulator solution motor 1 reaches the control mixing material and contains the sand ratio.

This separation type screw conveyer realized adding continuously sand, solved the oil field for many years in the wellfracturing construction operation because of the technical barrier that sand interrupts influencing the pressing crack construction quality occurring adding.
