Abstract
The invention discloses a method for preventing a pumping waste rock filling system from being jammed. The invention is mainly characterized in that an iron removal device is arranged at a waste rock discharge belt; the grate structure of the crusher is changed into a snaillike structure; and the working pressure of the hydraulic system, all the parameters of the pipelines and the slump of the waste rock slurries are controlled. Due to the above measures, the invention guarantees the smoothness during the conveying of the waste rocks such that the filling operation can be carried out smoothly.
Description
Technical field
The present invention relates to waste filling system under the coal mine.
Background technology
Cover for the coal seam that the condition of depositing is poor, the mine of balk, in opening driving, can produce a large amount of spoils.In order to digest spoil, realize spoil not gug, do not go up a hill, directly pulverize spoil in the down-hole in the colliery that has, and utilizes the gangue delivery pump will carry waste filling to the goaf.Through the industry operation, the plugging phenomenon often takes place, run duration needs detaching pipelines to handle.Therefore need explore the method that waste rock pumping and filling system prevents the plugging technology.
Summary of the invention
The objective of the invention is to propose a kind of method that prevents the plugging of filling pipeline at spoil plugging problem.
For reaching the purpose that prevents plugging, the present invention by the following technical solutions:
1. the discharge refuse belt is installed tramp iron separator, and crushing engine bamboo comb structure changes snail type into by van-type, and the assurance spoil is fully pulverized,
2. the hydraulic system of spoil delivery pump need be 16～20Mpa with operating pressure, outlet pressure 8～12Mpa.
3. adopting wall thickness is the ultra-high pressure pipeline of 10mm, diameter 159mm, ensures the antiknock ability of pipeline.30Mpa high pressure pipe clamp and high-pressure seal ring are adopted in the connection of pipeline enclosure, prevent that liquid from extruding from the pipe clamp gap, guarantee that sealing is permanent reliable.
4. when arranging pipeline, reduce bend as far as possible and shorten length of pipeline.
5. stir after adding water, make the slump of spoil slurry be controlled at 180-200mm.
6. first pump water before the pumping spoil, the part that the grain bucket of the moistening pump of water, pump chamber, conveyance conduit etc. contact with spoil; Add sponge ball behind the pump water, spoil material and water are isolated, avoid spoil material segregation.
7. can cause pipeline to produce vibration when the pressure of spoil delivery pump raises suddenly, adopt positive and negative pump crawl to handle.
The present invention has guaranteed that spoil is not stifled in carrying owing to adopt above measure, and filling operation is carried out smoothly.
Description of drawings
Fig. 1 is a pumping spoil treatment system process chart.
Among the figure: 1-feeder, 2-discharge refuse belt, 3-crushing engine, 4-charging belt, 5-mixer, 6-delivery pump, 7-carrier pipe, 8-waste bin, 9-tramp iron separator, 10-slide cash skewed slot.
The specific embodiment
The present invention is further described with reference to accompanying drawing:
Digging gangue is transported to exploiting field waste bin 8, spoil by feeder 1 through discharge refuse belt 2 with slip cash skewed slot 10 to crushing engine, by entering charging belt 4 after crushing engine 3 fragmentations, wherein on the discharge refuse belt 2 tramp iron separator 11 is installed, the bamboo comb of removing the impurity crushing engine 3 in the spoil adopts snail type, spoil is fully pulverized, unload to mixer 5 by charging belt 4, simultaneously in mixer 5, inject water, water injection rate should guarantee that the slump of spoil slurry is controlled between the 180-200mm, delivery pump 6 is gone in the back slide that stirs, and is filled to the goaf by delivery pump 6 through carrier pipe 7; Wherein to adopt wall thickness be the ultra-high pressure pipeline of 10mm, diameter 159mm for carrier pipe 7, ensures the antiknock ability of pipeline, and 30Mpa high pressure pipe clamp and high-pressure seal ring are adopted in the connection of pipeline enclosure, prevents that liquid from extruding from the pipe clamp gap, guarantees that sealing is permanent reliable; The hydraulic system working pressure 16-20Mpa of delivery pump 6, outlet pressure 8-12Mpa.In addition before the pumping spoil, should first pump water, it is fully moistening that every pump chamber that contacts with spoil, hopper, conveyance conduit are carried out, and moistening back adds sponge ball, pumping spoil again.When the pressure of spoil delivery pump 6 raises suddenly, can cause pipeline to produce vibration, adopt positive and negative pump crawl to handle.
Claims (1)
