Abstract
The utility model discloses an atomized cement feeding device which comprises a cement tank with a material inlet and a material outlet. A pipe which is communicated with an outer high-pressure air source surrounds an outer peripheral surface of the cement tank. The side wall of the cement tank is provided with air inlets correspondingly with the position of the pipe. A nozzle communicated with the pipe extends from the air inlet into the inner chamber of the cement tank. The pipe is provided at the lower part of the tank body. The air inlets are symmetrically provided at the side wall of the cement tank. The atomized cement feeding device is advantageous in that: the flow state of cement is changed; the cement is descended with high-pressure airflow; the flow speed of the cement in the tank body is increased; the feeding amount of cement can be effectively controlled thereby adjusting the specific gravity of the cement slurry so that the specific gravity of the cement slurry can obtain 1.8-1.9 and the performance is stable; in emergency water blocking, the amount of cement injected in one day can be increased from 435 tons to 634 tons, the construction period is shortened and a highest record in the same industry of the whole country is created.
Description
Technical field
The utility model relates to charging gear, especially relates to the used atomizing cement charging gear in a kind of geology water blockoff aspect.
Background technology
In the characteristics karst collapse col umn grouting for water blocking engineering of colliery, because underworkings caves in, filling aggregate in order to reduce the loss of cement grout, must adopt big pump amount, high specific gravity slurries to carry out slip casting in a large number.In traditional grouting process, cement or by self gravitation decline feed or by the shaker vibration feed or adopt spiral transhipment feed, these feeding methods make the proportion of slurries can only reach about 1.5, if increase proportion again, can only lean on and artificial scrape cement in the ground pot and realize, seriously polluted and working environment is extremely abominable, labor strength greatly and efficient is low, the proportion of slurries is uncontrollable, makes the size performance instability.
The utility model content
The purpose of this utility model is to provide a kind of atomizing cement charging gear that can effectively control cement feeding coal, cement grout stable performance.
For achieving the above object, the utility model can be taked following technical proposals:
Atomizing cement charging gear described in the utility model, comprise the cement tank body that has the charging and discharging mouth, the outer peripheral face of described cement tank body is surrounded with the pipeline that is connected with the external high pressure source of the gas, the spaced apart air inlet port that is provided with on the sidewall of the cement tank body that adapts with described pipeline location, the nozzle that is connected with described pipeline extends in the described cementing tank intracoelomic cavity from described air inlet port place.
Described pipeline is arranged on the bottom of described cement tank body, and described air inlet port symmetry is opened on the cementing tank body sidewall.
Described high-pressure air source is an air compressor machine, is serially connected with by-pass valve control, oil water separator and dryer successively on the pressure-air output pipe of described air compressor machine.
Advantage of the present utility model has been to change the fluidised form of cement, with high pressure draught cement is descended, and has accelerated the flowing velocity of cement in tank body, can effectively control the ash of giving of cement measures, thereby adjust the proportion of cement grout, make the proportion of cement grout can reach 1.8～1.9, and stable performance; When speedily carrying out rescue work water blockoff, a day cementing amount can be brought up to 634 tons by original 435 tons, has shortened the construction period, has created the tidemark of the national same industry.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, atomizing cement charging gear described in the utility model, comprise the cement tank body 1 that has the charging and discharging mouth, the outer peripheral face of described cement tank body 1 bottom is surrounded with the pipeline 2 that is connected with the pressure-air efferent duct of air compressor machine 4, on the pipeline between air compressor machine 4 and the pipeline 2, be serially connected with by-pass valve control 5, oil water separator 6 and dryer 7 successively, oil water separator 6 and dryer 7 can multistagely be provided with, guarantee that the pressure-air that feeds in the cement tank body 1 is pure, to prolong the application life of nozzle 3; Symmetry offers air inlet port on the sidewall of the cement tank body 1 that adapts with pipeline 2 positions, and general air inlet port is offered three and can be satisfied use; The nozzle 3 that is connected with described pipeline 2 extends in described cement tank body 1 inner chamber from described air inlet port place.
During work, cement is poured in the tank body from the upper inlet of vertical cement tank body 1, start air compressor machine 4, air compressor machine 4 output gases at high pressure, through valve 5, oil water separator 6, dryer 7 and by-pass valve control 8, after moisture contained in the pressure-air and oil content removing totally, nozzle 3 from cement tank body 1 bottom ejects, cement in the tank body is atomized, and gases at high pressure have changed the fluidised form of cement in the jar, have accelerated the downward movement velocity of cement, guarantee that cement flows into the spray can 9 from the below outlet as requested, because what can guarantee cement gives the ash amount, the proportion that can make slurries is brought up to 1.8-1.9 from 1.5, has satisfied the requirement of speedily carrying out rescue work.
