Abstract
The invention provides a coke oven heat-state pumping grouting construction method. The coke oven heat-state pumping grouting construction method comprises the following construction steps: arranging a slurry mixer on a middle platform or an end platform, arranging a slurry storage box in the front of the slurry mixer, and arranging a vertical slurry pump in the storage box; putting up a support frame with the height of 500 to 600 mm on the top of a furnace, and fixing a main slurry pipeline on the support frame, wherein one end of the main slurry pipeline is connected with the vertical slurry pump; arranging grouting branch pipes at the two sides of the main slurry pipeline at intervals, and arranging stop valves between the grouting branch pipes and the main slurry pipeline; and in the whole grouting process, injecting slurry into each grouting branch pipe all the time, and controlling the stop valve on each grouting branch pipe so as to realize the control on grouting points; and after the periodical grouting is finished, pumping clean water by the vertical slurry pump so as to clean the pipeline. The coke oven heat-state pumping grouting construction method has the advantages that a conventional manual conveying manner is replaced by a manner of conveying the slurry by the pipelines, so that the labor intensity of workers is greatly alleviated, the setting rate of slurry is reduced, the working efficiency is improved, the construction cost is reduced, and the construction period is shortened.
Description
Technical field
The present invention relates to a kind of coke oven grout construction method, specifically the hot pumping grout construction method of a kind of coke oven.
Background technology
In the coke oven construction process, the hot grouting of furnace roof and protecting sheet accounts for 70% of hot construction amount.Coke oven enters hot construction and indicates that coke oven is about to put into operation, and furnace roof and protecting sheet grouting are again the work that must complete before coke oven is gone into operation, and the heat that coke oven distributes is larger, and the mud setting rate is very fast, so the transportation of mud is comparatively arduous.Present transporting method mostly is artificial transportation, and because hot furnace roof and protecting sheet grouting operating ambient temperature is higher, workman's physical consumption is larger, and labour intensity is large, and inefficiency restricts whole construction speed.
Summary of the invention
The present invention be directed to the deficiency that exists in the hot grouting technique of present coke oven, provide a kind of and reduce the mud setting rate, need not manually to transport the hot pumping grout construction method of coke oven of mud.
Realize that the technical scheme that above-mentioned purpose adopts is: the hot pumping grout construction method of a kind of coke oven, construct according to following steps:
A, slurry mixer be arranged on coke oven one side between platform or the end platform on, a mud torage tank is set before slurry mixer, in this torage tank, Veritical mud pump is housed;
B, at the oven top of coke oven scaffolding height, be the bracing frame of 500-600mm, fixing mud main pipe line on bracing frame, an end of this mud main pipe line is connected with Veritical mud pump;
C, at the interval, both sides of mud main pipe line, the slip casting arm is set respectively, is provided with stopping valve between each slip casting arm and mud main pipe line;
D, start Veritical mud pump and be in the milk, in whole filling process, each slip casting arm keeps logical slurry, by controlling stopping valve on each slip casting arm, realizes control to slip casting point;
When e, the end of filling stage property, with Veritical mud pump pumping clear water, pipeline is cleaned.
Adopt the DN50 high-pressure air hose to connect between mud main pipe line and Veritical mud pump.
The mud main pipe line adopts the weldless steel tube of Φ 48.
Every five carbonizing chambers, a slip casting arm is set on the mud main pipe line.
The mud main pipe line is arranged along the horizontal center line of oven top of coke oven.
The slurry output end of each slip casting arm is installed respectively one section steel pipe.
The slip casting arm respectively evenly interval be arranged in the both sides of mud main pipe line, control one-sided slip casting or bilateral slip casting by each stopping valve.
This constructional method disclosed in this invention has substituted traditional artificial transportation with the pipeline slurry conveyed, greatly reduces workman's labour intensity, reduces the setting rate of mud, increases work efficiency, and reduces construction cost, the reduction of erection time.
Description of drawings
Fig. 1 is equipment layout schematic diagram of the present invention.
In figure: a platform 1, slurry mixer 2, mud torage tank 3, Veritical mud pump 4, mud main pipe line 5, slip casting arm 6, stopping valve 7, furnace roof 8, end platform 9.
Embodiment
The present invention will be further described below in conjunction with drawings and Examples.
Referring to accompanying drawing 1, the hot pumping grout construction method of this coke oven disclosed in this invention, construct according to following steps.
A, a platform 1 and end platform 9 are separately positioned on the both sides of coke oven, slurry mixer 2 be arranged on coke oven one side between on platform 1, a mud torage tank 3 is set before slurry mixer 2, the mud torage tank is generally rectangle, its size is according to the service condition field fabrication.Veritical mud pump 4 is housed in mud torage tank 3, and the present embodiment adopts the PNL Veritical mud pump.
B, at oven top of coke oven 8 scaffolding heights, be the bracing frame of 500-600mm, the scaffolding of working-yard gets final product, and fixing mud main pipe line 5 on bracing frame, be fixed on mud main pipe line 5 on bracing frame with web members such as tying up silk.The mud main pipe line is along the horizontal center line layout of oven top of coke oven 8, and an end of mud main pipe line 5 and Veritical mud pump 4 adopt the DN50 high-pressure air hoses to link together, and the mud main pipe line adopts the weldless steel tube of Φ 48.
C, at the interval, both sides of mud main pipe line 5, slip casting arm 6 is set respectively, is provided with stopping valve 7 between each slip casting arm 6 and mud main pipe line 5; Every five carbonizing chambers, a slip casting arm 6 is set on the mud main pipe line, the slurry output end of each slip casting arm 6 is installed respectively one section steel pipe, and is easy to use, and the length of slip casting arm 6 is definite according to having a lot of social connections.The slip casting arm generally adopts sebific duct, convenient mobile slip casting point.
D, start Veritical mud pump and be in the milk, in whole filling process, each slip casting arm keeps logical slurry, by controlling stopping valve on each slip casting arm, realizes control to slip casting point; Pulp absorbing hole at Veritical mud pump is wrapped with gauze, avoids the clod that does not stir to be inhaled into and causes line clogging.In the pumping filling process, if suspend slip casting, valve is turned down, forbid to shut, connect the mud of outflow with liquid dump bailer; If intermittently long-time or stage stops grouting, with Veritical mud pump pumping clear water, pipeline is cleaned, prevent from stopping up.
