Description
Technical field
The utility model relates to a kind of pulping system, especially a kind of pulping system that is applicable to the preventing and extinguishing fire of coal mine of coal-mine fire improvement and coal spontaneous combustion tendency fire incident.
Background technology
It is that loess or flyash, mine tailing etc. are mixed with a certain proportion of water that fire-fighting technique is put in colliery grouting, processes uniform slurries, is transported to fire and intends treatment region anti-fire extinguishing of being in the milk.By the mud solution that loess is processed,, need not handle the ability that can realize long distances to slurries owing to self have good mobility.The slurries that have flyash, mine tailing, sandy soil etc. to process then need add thickening agent and process colloid and carry at a distance.
Want to process qualified slurries, colloid, realize the function that long-distance transportation is respond well with fire extinguishing, wherein the preparation of even chylema liquid is a prerequisite.At present; The pulping process at surface grout injection station mainly contains two kinds: the centrifugal pulp-making method of (1) Zaozhuang Suda Motor Engineering Company utility model; Its shortcoming is: because this kind equipment adopts the method for centrifugal slurrying, the specific yield of slurries is lower, along with being on the increase of Chinese large-sized mine; When also increasing, this kind method should not be used to the requirement of fire extinguishing slurries consumption; Slurries unit energy consumption by centrifugal slurrying produces is also higher, and economy is lower, does not satisfy the requirement of national energy-saving and emission-reduction; This kind scheme deslagging is inconvenient, and sealing effectiveness is bad, and labor strength is bigger like this, and machine run efficient is lower.(2) defective of the pulping process of the gloomy the orchid family trade in Xi'an Co., Ltd utility model is: do not have special-purpose crushing appliance, can't solve the utilization to north frozen soil in winter, cause waste of raw materials; Because on-the-spot used material contains other hard material such as more impurity such as stone; In the preliminary filtration of feeder, also can't be screened this type impurity; Because system does not have crushing appliance, and impurity will directly get into filter inside and carry out screening and filtering, hard here bulk materials and filter screen carry out collision friction simultaneously; Very easily cause the damage of thick worry filter screen, cause the start efficient of complete machine to reduce; When needs prepare colloid; This system is employed in a thickening agent spiral adding machine is housed on two pipelines between the filter; Have mud flow to bring lower floor's filter at this additive, that leans on filter mixes the preparation colloid, because the flow of this equipment is to lean on gravity free-pouring; Gellant material can not be carried out full and uniform mixing after adding lower floor's filter, can't the good colloid of processability.
Summary of the invention
Technical problem: the purpose of the utility model is the weak point that will overcome in the prior art, and a kind of pulping system that is used for preventing and extinguishing fire of coal mine that improves utilization rate of raw materials, slurrying efficient height, service life of equipment length is provided.
Technical scheme: the pulping system that is used for preventing and extinguishing fire of coal mine of the utility model; Mainly form by the oscillating feeder that links to each other with automatic control system, beater, belt conveyor, grinding pulper, double medium filtration machine, glue making machine; Wherein: the front portion of oscillating feeder is provided with hopper; The rear portion of oscillating feeder is connected with beater, and the outlet of beater is provided with the pulp tube that material is sent to belt conveyor, and the grinding pulper is located at belt conveyor outlet below; Grinding pulper and double medium filtration machine link, and the double medium filtration machine is connected with glue making machine by the road.
Described grinding pulper mainly by grinding slurrying tube, be located at turning cylinder on the grinding slurrying tube, the band drive that links to each other with turning cylinder constitutes with the motor that links to each other with the band drive; Be interval with a plurality of rotating disks on the turning cylinder; Be evenly distributed with a plurality of abrasion-proof backing blocks on the rotating disk; Grinding slurrying tube clockwise direction one side lower part is provided with the adjustable friction plate, and grinding slurrying tube clockwise direction opposite side bottom is provided with guide shell; Described double medium filtration machine comprises Inner filter net and the outer leaching net that filters machine barrel, the tapered net of mutual sheathing in filtering machine barrel; Inner filter net and outer leaching net are located at respectively on two bearing supports on the filter support through sleeve; The filtration machine barrel exports an end inboard and is provided with slag-draining device; The filtration machine barrel exports the end outside and is provided with the filter transmission system, filters machine barrel clockwise direction one side lower part and is provided with the pulp tube.
Beneficial effect: owing to adopted technique scheme, plurality of devices is combined, the each several part equipment level is ladder pattern distribution, and the slurries that anterior equipment is processed flow to rear portion equipment through potential energy difference, have practiced thrift the energy so greatly.Adopt quickly preparing cement paste and double-layer leaching net to filter the combination pulping way in addition, improved the slurrying capacity and the efficient of equipment greatly, the slurries unit energy consumption of having avoided centrifugal slurrying to produce is also higher, and economy is lower, the big traditional problem that waits of hand labor.Can realize fragmentation utilization, improve utilization rate of raw materials north frozen soil in winter; To the hard raw-material grinding of little bulk, avoid hard bulk materials and filter screen to carry out collision friction, cause the damage phenomenon of thick worry filter screen, increase the application life of equipment, improve start efficient.
