Abstract
The utility model provides pre-spraying equipment capable of controlling the feeding quantity for dust removing of a coke oven, relates to equipment used for removing dust of the coke oven and conducting ash pre-spraying on a dust removing cloth bag, and solves the problem of the conventional pre-spraying equipment that blanking speed cannot be observed and controlled. The pre-spraying equipment provided by the utility model comprises a pre-spraying bin, a formatted feeder, a motor and an ash spraying pipe, wherein the formatted feeder is arranged at the lower reversely tapered part of the pre-spraying bin; the motor shaft of the motor is connected with the rotating shaft of the formatted feeder; the discharge opening of the formatted feeder is communicated with the ash spraying pipe; the pre-spraying equipment further comprises a hand-operated gate valve; the hand-operated gate valve is arranged at the lower reversely tapered part of the pre-spraying bin above the formatted feeder, so as to control the blanking quantity of material flowing into the inlet of the formatted feeder; and the air inlet of the ash spraying pipe is adjacent to the discharge opening of the formatted feeder. The reformed project is suitable for all coking enterprises adopting ground dust removing equipment; and the utility model has the advantages that the effect of the reformed pre-spraying equipment is obvious, the suction force of a smoke guide vehicle can be trebled, and the fuming phenomenon during coal filling can be eliminated approximately.
Description
Technical field
That the utility model relates to is that a kind of pit kiln dedusting is used, spray the equipment of ash in advance to dust-removal cloth-bag.
Background technology
Present medium-sized pit kiln generally all is the situation of smoldering when adopting ground station for dust removal to handle coal.The ground station for dust removal dust collecting process mainly is by the negative-pressure sucking that the dedusting fan high-speed cruising is produced the raw gas that is produced in the coal process to be drawn onto ground station for dust removal to carry out smoke prevention and dust control, and the carbonic acid gas that produces after the dedusting is discharged.In this technology, dust-removal cloth-bag is the link of most critical, and its ventilation property quality is directly connected to the suction on the smoke guiding bogie on the stove.Breathe freely, suction is just big, just can not smolder during coal.On the contrary, suction is little, and it is just big to smolder, and raw gas will be discharged into contaminate environment in the atmosphere.Guarantee the ventilation property of cloth bag, what have played critical effect again to the upward ash amount of pre-spraying.Because blower fan all is that raw gas that the negative pressure that produces during with high-speed cruising produces during coal is drawn onto ground station for dust removal and carries out smoke prevention and dust control during each coal, in the blower fan superhigh speed, dedusting ash is sent in the form material feeder action of pre-spray position below, compress wind blows to the coke powder ash in the vacuum lines simultaneously, the negative pressure that produces by blower fan is drawn onto the cloth bag surface to dedusting ash again, during coal in the raw gas contained water and tar be isolated in outside the dedusting ash.Whether at present the problem that exists is: stop up and what of the amount of blanking owing to can't observe the form material feeder, also uncontrollable blanking velocity, therefore for dedusting reliably, often many blankings, cause the dedusting ash that sprays to the dust-removal cloth-bag surface more, reduced suction raw gas.
Summary of the invention
The purpose of this utility model provides the pre-spraying equipment that can control feeding coal that a kind of pit kiln dedusting is used, and can't observe and control the problem of blanking velocity to solve the pre existing spraying equipment.It comprises pre-spray position 1, form material feeder 6, electric motor 3 and ash-blowing tube 4, form material feeder 6 is arranged on the following back taper place of pre-spray position 1, the motor shaft of electric motor 3 is connected with the turning axle of form material feeder 6, the discharge port of form material feeder 6 is connected with ash-blowing tube 4, it also comprises manual push-pull valve 7, the following back taper that manual push-pull valve 7 is arranged on the pre-spray position 1 of form material feeder 6 tops is sentenced the blanking amount that control flow into form material feeder 6 inlets, and the discharge port of the blast inlet of ash-blowing tube 4 and form material feeder 6 is adjacent.
One end of ash-blowing tube 4 is as blast inlet, also whether stops up porthole with blanking velocity as observing form material feeder 6 simultaneously.The other end of ash-blowing tube 4 connects the air-vent of blower fan, by the negative-pressure sucking suction that blower fan produces, is delivered to the dedusting ash of pipeline inside during each coal in the pre-spraying pipeline by the form material feeder, can be drawn onto the dust-removal cloth-bag surface by the negative-pressure air-flow of blower fan oneself generation.Manually push-pull valve 7 can be controlled pre-spray material amount.Observe the blanking situation by blast inlet, suitably regulate manual push-pull valve aperture control blanking amount, under the prerequisite that guarantees pre-spray effect, guarantee the dust-removal cloth-bag ventilation property and the blower fan resistance pressure reduction during coal is controlled at minimum, so just can guarantee the suction of blower fan, smolder when stopping coal.This transformation project is applicable to all coal chemical enterprises that use ground dedusting equipment, and it is obvious to transform the back effect, and the suction on the smoke guiding bogie can increase twice, and the phenomenon of smoldering during coal can be stopped substantially.
