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 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 mud setting rate is very fast, so the transportation of mud is comparatively arduous.Present transporting method mostly is artificial transport, 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 existing in the hot grouting technique of current coke oven, a kind of mud setting rate, hot pumping grout construction method of coke oven without artificial transport mud of reducing is provided.
The technical scheme that realizes above-mentioned purpose employing 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 end platform on, a mud torage tank is set before slurry mixer, in this torage tank, Veritical mud pump is housed;
B, the bracing frame that is 500-600mm at oven top of coke oven scaffolding height are fixed mud main pipeline on bracing frame, and one end of this mud main pipeline is connected with Veritical mud pump;
C, at the interval, both sides of mud main pipeline, slip casting arm is set respectively, between each slip casting arm and mud main pipeline, is provided with stopping valve;
D, startup Veritical mud pump are in the milk, and in whole filling process, each slip casting arm keeps logical slurry, realizes the control to slip casting point by the stopping valve of controlling on each slip casting arm;
When e, filling stage property finish, pipeline is cleaned with Veritical mud pump pumping clear water.
Between mud main pipeline and Veritical mud pump, adopt DN50 high-pressure air hose to connect.
Mud main pipeline adopts the weldless steel tube of Φ 48.
On mud main pipeline, every five carbonizing chambers, a slip casting arm is set.
Mud main pipeline 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 of steel pipe.
Slip casting arm respectively evenly interval be arranged in the both sides of mud main pipeline, by the one-sided slip casting of each stopping valve control or bilateral slip casting.
This constructional method disclosed in this invention has substituted traditional artificial transport by 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.
Brief description of the 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 pipeline 5, slip casting arm 6, stopping valve 7, furnace roof 8, end platform 9.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
Referring to accompanying drawing 1, the hot pumping grout construction method of this coke oven disclosed in this invention, constructs 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, mud torage tank is generally rectangle, its size is according to service condition field fabrication.Veritical mud pump 4 is housed in mud torage tank 3, and the present embodiment adopts PNL Veritical mud pump.
B, the bracing frame that is 500-600mm at oven top of coke oven 8 scaffolding heights, the scaffolding of working-yard is fixed mud main pipeline 5 on bracing frame, mud main pipeline 5 is fixed on bracing frame with web members such as tying up silk.Mud main pipeline is along the horizontal center line layout of oven top of coke oven 8, and one end of mud main pipeline 5 and Veritical mud pump 4 adopt DN50 high-pressure air hose to link together, and mud main pipeline adopts the weldless steel tube of Φ 48.
C, at the interval, both sides of mud main pipeline 5, slip casting arm 6 is set respectively, between each slip casting arm 6 and mud main pipeline 5, is provided with stopping valve 7; On mud main pipeline, every five carbonizing chambers, a slip casting arm 6 is set, the slurry output end of each slip casting arm 6 is installed respectively one section of steel pipe, easy to use, and the length of slip casting arm 6 is definite according to having a lot of social connections.Slip casting arm generally adopts sebific duct, facilitates mobile slip casting point.
D, startup Veritical mud pump are in the milk, and in whole filling process, each slip casting arm keeps logical slurry, realizes the control to slip casting point by the stopping valve of controlling on each slip casting arm; Pulp absorbing hole at Veritical mud pump is wrapped with gauze, and the clod of avoiding not stirring is inhaled into and causes line clogging.In pumping filling process, if suspend slip casting, valve is turned down, forbid to shut, connect the mud of outflow with liquid dump bailer; If long-time intermittently or stage stop grouting, pipeline is cleaned with Veritical mud pump pumping clear water, prevent obstruction.
