Description

Quick pulping device

Technical field

The present invention relates to a kind of well-digging auxiliary equipment, particularly a kind of quick pulping device of making well-digging with mud.

Background technology

At present, drilling well all is to adopt earlier the loess piece to be soaked with the preparation of mud, loess after will soaking then utilizes mixer to stir the process of pulping, because the method is soaked required time generally 2 days even longer time, thereby cause long, inefficient problem of pulping time in the process of constructing well.

Summary of the invention

The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of soaking-free is provided, directly carry out pulping, and can be with the quick pulping device of the sandstone filtering in the mud.

For achieving the above object, technical scheme of the present invention is: a kind of quick pulping device, comprise cyclone, slush pump and rack-mounted vertical crusher, the discharging opening that it is characterized in that the vertical crusher lower end links to each other with the charging aperture of blender upper end, on the pulverization cylinder inwall of above-mentioned vertical crusher, be fixed with the shading ring of ring-type, shading ring is between two pendulums on the vertical crusher main shaft, lower end and upper end at blender are separately installed with water inlet pipe and mud efferent duct, above-mentioned water inlet pipe links to each other with the slush pump delivery port, one bye-pass is installed on water inlet pipe, link to each other by triple valve between one end of bye-pass and the water inlet pipe, the other end of bye-pass links to each other with cyclone.

Above-mentioned is the tubular closed container at blender, the charging aperture of blender upper end is connected with the discharging opening of vertical crusher lower end, on the charging aperture in blender tremie pipe is installed, with the tremie pipe corresponding position annular batch mixing chamber is installed in the blender bottom, the water inlet of water inlet pipe is arranged in the annular batch mixing chamber.

It is to adopt to be tightly connected that the discharging opening of above-mentioned vertical crusher lower end links to each other with the charging aperture of blender upper end.

What above-mentionedly be tightly connected by the downward horn-like discharging opening of the microcephaly who is installed in the vertical crusher lower end, be installed in the horn-like charging aperture that major part that blender upper end and above-mentioned horn-like discharging opening match makes progress and be installed in the vertical crusher lower end forms with the concentric annular seal ring of horn-like discharging opening.

It is to adopt matched in clearance that the horn-like charging aperture that above-mentioned horn-like discharging opening and major part make progress matches.

The technical program is to utilize pulverizer that pulping is pulverized with the loess piece, utilizes the loess after blender will be pulverized to mix pulping with water then.Mud can directly use as required, also can enter cyclone separates, purifies, safety, high-quality, efficient, the low consumption of construction have been guaranteed, long, problems such as efficient is low, sandstone content height of present pulping time have been solved, compare with existing pulp making method, on same power of motor basis, increase work efficiency and mud amount of preparation 3-4 times.Rational in infrastructure, easy, the high characteristics of pulping efficient of combination installation that this programme has.

Description of drawings

Accompanying drawing 1 is a structure principle chart of the present invention.

The specific embodiment

As shown in Figure 1, on the frame 5 vertical crusher is installed, in the pulverization cylinder 3 of vertical crusher main shaft 11 is installed, motor pulley 1 is installed on the output shaft of pulverizer motor 2, the main shaft upper end links to each other with motor by belt pulley 12.Be fixed with the shading ring 4 of ring-type in pulverization cylinder, shading ring is between two pendulums on the vertical crusher main shaft.Blender 7 is the tubular closed container, its upper end is connected with the discharging opening 18 of vertical crusher by charging aperture 19, tremie pipe 6 is installed on the charging aperture in blender, with the tremie pipe corresponding position annular batch mixing chamber 8 is installed in the blender bottom, water inlet pipe 9 is installed in the blender bottom, and the water inlet of water inlet pipe is arranged in the annular batch mixing chamber.Mud efferent duct 10 is installed in blender top.

Slush pump is placed in the mud pit, and the mud delivery side of pump links to each other with water inlet pipe 9, and a bye-pass 20 is installed on water inlet pipe, links to each other by triple valve 21 between an end of bye-pass and the water inlet pipe, and the other end of bye-pass links to each other with cyclone 15.Cyclone adopts existing equipment, its inside has agitator, and it mainly acts on is that the sandstone in the mud are separated, purify, and the sandstone after the separation are discharged by the slag-drip opening 16 of cyclone bottom, mud after the purification is discharged by the grout outlet 14 of cyclone upper end, enters mud pit.

Dust when entering in the blender for the loess after reducing to pulverize, being tightly connected between the charging aperture 19 of the discharging opening 18 of vertical crusher and blender upper end is in forming with the concentric annular seal ring 17 of horn-like discharging opening of using by the downward horn-like discharging opening 18 of the microcephaly who is contained in the vertical crusher lower end, be installed in the horn-like charging aperture 19 that major part that blender upper end and above-mentioned horn-like discharging opening match makes progress and be installed in the vertical crusher lower end, is the employing matched in clearance between discharging opening and the charging aperture.

During use, at first triple valve 21 is rotated to and close bye-pass 20, open the position that enters the blender pipeline, starter motor drives main axis rotation, the pulping that needs are pulverized is put into pulverizer with the loess piece by hopper 13, the loess piece is pulverized by the pulverizing hammer that is installed on the main shaft.Because the effect of shading ring makes the loess piece be divided into different layers in the process of pulverizing, under the situation that does not increase pendulum quantity and power of motor, the degree of grinding of loess particle can improve more than 20%.Loess after the pulverizing is entered in the annular batch mixing chamber of blender by the pulverizer discharging opening, by slush pump the mud in the mud pit is squeezed in the annular batch mixing chamber by water inlet pipe, mix formation mud with the loess after pulverizing, mixed mud is directly exported for using by mud efferent duct 10.

After wellbore construction begins, do not need to prepare mud, then triple valve 21 is rotated to and close the pipeline that enters blender, unlatching enters the position of cyclone bye-pass 20, directly squeeze into mud in mud pit in cyclone by slush pump this moment, return mud pit by the mud after the cyclone purification by grout outlet 14, the sandstone that purify are discharged by the slag-drip opening 16 of cyclone bottom.
