Abstract
The utility model relates to a ventilation quenching arch breaking device of a cement shaft kiln. The utility model is characterized in that an original air supply pipeline is additionally provided with an air inducing pipe, and the pipe is led to a wind distributor arranged on the middle part of the shaft kiln; the distributor is provided with an annular air pipeline, a plurality of branch air pipes and jet pipes tilted in and led to the kiln, and the jet pipes are correspondingly communicated with branch water pipes on a watercooling supplier. A plurality of air supplying air current and water fog can be sprayed in a room at a high speed through the jet pipes, and thus the aim of ventilation quenching arch breaking at the middle part of the shaft kiln is realized. The device has the advantages of simple structure, strong practicability, coal saving, electricity saving and high production.
Description
The utility model relates to a kind of servicing unit of producing clinker equipment, especially for the ventilation chilling arch breaking apparatus in the mechanized cement shaft kiln.
Usually, in the process of mechanized cement shaft kiln calcination of cement clinker, the air supply device of shaft kiln is made up of blower fan and an air supply line, the weak point of this device is: because the wind-force that airduct road provides is the bottom air feed in kiln by shaft kiln, form shaft kiln middle part wind-force deficiency easily, and the inclined to one side fire of limit wind surplus, wind phenomenon partially cause that caking appears in clinker in the kiln, form the bow member abnormal conditions such as kiln and big block abrading block, fiery piece that do not fall.Particularly because the apoplexy deficiency, cool off bad, limit, middle part portion excessive temperature differentials, and the kiln internal combustion is insufficient, thereby cause that coal consumption in the production process is higher, output is on the low side, quality shakiness etc., not only give and bring unsafe sunken trouble in producing, and influenced the service life of equipment.
The purpose of this utility model is to overcome the deficiency of prior art and provide a kind of improvement machine shaft kiln middle part to ventilate, and avoids occurring in the kiln cement in vertical kiln ventilation chilling arch breaking apparatus of fire, inclined to one side wind phenomenon partially.
Realize that the scheme that this reality has novel purpose to take is: this device is to improve to form on the basis of machine shaft kiln air supply device, mainly by induced duct, the wind distribution device, the water-cooled feeder is formed, its architectural feature is: the place sets up induced duct at air supply line, this pipe leads to the wind distribution device that the shaft kiln middle part is provided with, the wind distribution device is by annular shape airduct road, branch wind pipe, jet pipe is formed, wherein, the air loop duct road is along the shaft kiln circumferential directions, uniform on it a plurality of branch wind pipes are set, identical and the tilting jet pipe that leads in the kiln is housed on each branch wind pipe, be provided with the water-cooled feeder on the top of wind distribution device, be by water pump, the annular water cooled pipeline, branching pipe is formed, be evenly equipped with and the corresponding branching pipe of jet pipe on the circumference of annular water cooled pipeline, and communicate with jet pipe.Its course of work is: the wind-force that blower fan is supplied with is introduced the wind distribution device by the inlet tube of setting up on the airduct road, the puff prot of jet pipe on the wind distribution device, draft is drawn high fast direction kiln center, in air feed, water is passed through annular water cooled pipeline, send into jet pipe with branching pipe, water is under the effect of high speed draft, be dispersed into the droplet shape, puff prot through jet pipe sprays in the kiln, thereby make the clinker quenching of high temperature bulk and hardening crack, realized the broken arch of kiln ventilation chilling.In addition, can be by wind control valve, the Hydraulic-control valves that is provided with in the adjusting device, the air-flow of adjustment air feed air-flow and water-cooled flow distributes, to adapt to the variation of calcining situation in the kiln, to reach the purpose of administering fiery, inclined to one side partially wind.
The cement in vertical kiln ventilation chilling arch breaking apparatus of making according to such scheme, simple in structure, old kiln, new kiln all can be installed, under this device ad hoc structure condition, suitably regulate the expulsion pressure and the water-cooled flow of 4～10 bursts of drafts on the jet pipe, draft is entered form suitable water droplet thick fog field in the kiln, air-flow field and temperature field, become the stable ventilation water-cooled source, center, kiln middle part of introducing, can be to playing good cooling effect in the kiln, simultaneously also prolong the service life of shaft kiln, and can save a large amount of coal consumptions, power consumption has improved output, guaranteed safety.The production experimental result shows: the kiln discharge clinker temperature descends 50 ℃～100 ℃ than original; Grog burns till coal consumption and descends 5%～15%; The shaft kiln unit-hour output increases more than the 0.5t/h, and clinker strength increases by 2～5Mpa.
Utilize accompanying drawing to further describe embodiment of the present utility model below;
Fig. 1 is the utility model structural representation.
Referring to Fig. 1, present embodiment can utilize set up induced duct 4 on blower fan that original shaft kiln 1 uses 2, airduct road 3, the pipeline 3 and be connected with air loop duct road 5 that the shaft kiln middle part is provided with, air loop duct road 5 is along the setting of shaft kiln circumferencial direction, a uniform 4-10 branch wind pipe 6 on it, each branch wind pipe is provided with tilting jet pipe 8, jet pipe 8 is cone-shaped, the front portion is provided with the puff prot of jet-stream wind, and puff prot passes the kiln wall, leads in the kiln.The size of tool certain included angle, angle is to determine according to kiln footpath, kiln height between tributary pipe 6 and the jet pipe 8, also is provided with wind control valve 7 between the two.Be provided with annular water cooled pipeline 10 on the top in air loop duct road 5, be evenly equipped with on the circumference of pipeline 10 and jet pipe 8 corresponding branching pipe 10a, and communicate with jet pipe 8, be provided with Hydraulic-control valves 11 therebetween, label 12 is the water control total valve, is connected (not shown) with the water pump that is provided with.
For preventing that jet pipe 8 from being stopped up by the clinker particle, air outlet place at jet pipe 8 is provided with grid section, the bottom of jet pipe 8 is provided with discloses material pipe 9, be used for the particulate dust that timely removing accumulates in jet pipe 8 side by side, not accumulated powder slagging scorification when jet pipe 8 interior dust-containing air streams are passed through, safe and reliable, can use continuously for a long time.
