Description
Technical field
The utility model relates to a kind of industrial shaping coal drying oven.
Background technology
Existing industrial shaping coal drying oven is cellar for storing things, tunnel, the dry cellar for storing things of the row's of returning formula, and the cellar for storing things is mixed for changeing in the cellar for storing things, tunnel, and long 50m-80m goes into dry back the tunnel, cellar for storing things with cellar for storing things car dress moulded coal from feeding gate and goes out the cellar for storing things from discharge door, and be 4-6 hour drying time, adopts power 20-30kw.At present most widely used is the dry cellar for storing things of the row's of returning formula, and the XH98-3 that designs as China Mining University returns the dry cellar for storing things of row's formula.By per hour dry 10 tons be example, generally be designed to layer 2-4, long 40m-80m adopts power to add up to 40-70kw 2-4 hour drying time, above-mentioned two class industrial shaping coal drying oven floor spaces are big, invest greatly, power consumption is many, drying efficiency is low.
Summary of the invention
In order to overcome the deficiency that existing industrial shaping coal drying oven floor space is big, investment is big, drying efficiency is low, the utility model provides a kind of small investment, floor space is little, drying efficiency is high industrial shaping coal drying oven.
The technical scheme that the utility model is taked mainly is to have adopted vertical body of heater or inclination body of heater.Utilize in the process that the deadweight of moulded coal slides from the top down downslide limit, limit evaporation moisture content and do solid sclerosis in body of heater, when sliding at the bottom of the body of heater under the moulded coal enough bearing capacities are arranged, and it is broken pure to bear up the pressure of top moulded coal fully.Do not have the moving component that transports moulded coal in the body of heater, saved the power that in body of heater, transports moulded coal.A large amount of hot blasts in the row of the returning formula drying oven stove not work done and the phenomenon of wasting have been overcome, not only floor space is little, simple in structure but also the power consumption sum is few, and the employing cross section is the body of heater of rectangle, realize that not only total cross-section ventilates, drying efficiency obviously improves, and is convenient to be assembled into bigger combination body of heater.
The utility model comprises body of heater, bearing, bearing is fixed under the body of heater, body of heater has charging aperture, discharging opening, air inlet, drier, the moulded coal chamber, drier is arranged in the body of heater, drier is outward the moulded coal chamber, drier communicates with wind channel outside being arranged on body of heater through air inlet, fixing the infundibulate shell under the body of heater, the infundibulate shell is up big and down small, the lower end of infundibulate shell is a discharging opening, it is characterized in that, said body of heater is vertical body of heater or inclination body of heater, the inclination angle on body of heater and ground is 30 °-90 °, the cross section of body of heater is a rectangle, and drier is distributed in the body of heater with the moulded coal chamber is parallel with the symmetry axis of body of heater, in the sidewall of the drier blowhole that distributing, the upper end in moulded coal chamber is a charging aperture, and the lower end is a blanking port; 1-3 cloth triangle body is being set on the charging aperture at body of heater top, and the cloth triangle body is that upward sharp wide one-tenth cross section down is leg-of-mutton three stripe board that are fixed as one, and the cloth triangle body is installed on two end-stopping plates that are fixed on the body of heater top; Equal flitch is installed under the moulded coal chamber on the discharging opening in the infundibulate shell, and all flitch is to go up point two stripe board of wide one-tenth dihedral angle down, with the acting in conjunction of infundibulate shell the moulded coal in each moulded coal chamber is evenly fallen.
It is that the board-like drier effect of rectangle is better that the drier of body of heater can be arranged to cross section, and board-like drier and moulded coal chamber distribute alternately successively in body of heater, and the width that the width of board-like drier is generally 10-20cm, moulded coal chamber is generally 20-40cm.
The tube drier that the drier of above-mentioned body of heater can constitute with round steel pipe, tube drier is divided into plurality of rows and is arranged in the body of heater, the sidewall of the tube drier blowhole that distributing, tube drier is the moulded coal chamber of mutual UNICOM outward, there is horizontal how logical wind channel the upper end of every row's round steel pipe, connections that link of the upper end of round steel pipe and many logical wind channels, the two ends that lead to wind channel are air inlets more.
Above-mentioned body of heater also can adopt the inclination body of heater with upright the best.The inclination body of heater can reduce between the moulded coal piece the particularly pressure between lower floor's moulded coal.
For the ease of discharging dry good moulded coal, under the discharging opening of industrial coal stove, discharge device is set, discharge device can adopt the vibration discharge device, and the vibration discharge device has one to be " well " type vibrating grid, and the vibrator that has motor is installed on the vibrating grid.Flat board with the corresponding fixed-site of discharging opening on the vibrating grid greater than discharging opening, have between flat board and the discharging opening at interval, fixing installing plate, installing plate at the column of bearing wears the through hole of bolt, vibrating grid and is enclosed within on the bolt, the turret head of bolt down, overlapping spiral compression spring on the bolt, the through hole of vibrating grid is enclosed within on the spiral compression spring.Dried moulded coal drops on the flat board from discharging opening, and plate vibration shakes moulded coal to fall on the conveyer belt under the vibrating grid and sees off.
Discharge device of the present utility model also can adopt mechanical push-and-pull discharge device, the striker plate big or small and horizontal that discharging opening adapts promptly is installed under discharging opening, have between striker plate and the discharging opening at interval, striker plate connects with eccentric wheel and coupling bar pushing mechanism, but the translation of the striker plate left and right sides, striker plate retaining stops moulded coal to fall in discharging opening following time, when striker plate was removed, moulded coal was fallen the conveying rubber strip of belt conveyor from discharging opening.Discharge device of the present utility model also can adopt slip chute discharge device, a rotating chute promptly is articulated and connected under discharging opening, regulate the level angle between chute and the discharging opening, the size that can regulate the discharging cross section of chute and discharging opening, the speed of control discharging.
