Abstract

The utility model relates to a drying box of a host blast stove. A dehumidifying box is arranged between a left drying box and a right drying box; the left and the right ends of the left and the right drying boxes are provided with equilibrium hot blast boxes; the top of the dehumidifying box is provided with a waste heat recovery box in which a tube type heat exchanger is arranged, and the bottom of the waste heat recovery box is communicated with the dehumidifying box; the front end of the tube type heat exchanger is a fresh air suction hole, and the rear end thereof is provided with an air collection box; the end part of the air collection box is connected with an air inlet of a centrifugal fan, and an air outlet of the centrifugal fan is connected with an air inlet of the hot blast stove; and the top of the waste heat recovery box is opened, and is used as a dehumidifying hole. The drying box of a host blast stove effectively changes the flowing mode of hot blast to generate low air resistance, so that a relatively smaller fan can be selected, not only the electricity is saved, but also the temperature in the drying box is uniform, the drying quality is improved, and a large amount of heat energy is recovered from wet hot air discharged; therefore, the energy is saved.

Description

The hot-blast stove drying box

Affiliated field:

The utility model relates to a kind of drying device, Uniform Ventilation in the drying box especially, and upper and lower temperature difference is little and can reclaim the hot-blast stove drying box of suitable part heat energy

Background technology:

At present, known agricultural byproducts drying equipment, its structure is in the left and right sides of hot-blast stove drying box to be set.Hot-blast stove is sealing around, the square chest that the top is opened wide, combustion furnace places the below of square chest, one axial flow blower is set above combustion furnace, the dividing plate below adjacent with left and right sides drying box is provided with an air inlet, force air is flowed, and air is heated the back through combustion furnace and enters the below of left and right sides drying box from above-mentioned air inlet, passes in the drying box 15-20 layer with the material bed discharge of screen cloth splendid attire.The weak point of this technology is that the drying box temperature difference up and down is big, and the windage of hot-air is big, and flow velocity is slow, and the material that the middle part occurs is by the phenomenon of boiling, and rate of drying is slow, and arid cycle is long, the poor quality of the material that is dried, energy consumption height.

The utility model content:

In order to overcome the above-mentioned defective that existing agricultural byproducts drying equipment exists, the utility model provides a kind of hot-blast stove drying box, this drying box can improve the hot blast wind speed of flowing through material bed effectively, not only windage is little, and wind speed is even, avoided material in dry run by the phenomenon of boiling, thereby arid cycle can not only be shortened, improve the quality of dry materials, return ashamed case and reclaimed quite a few heat energy, reduced energy consumption owing to set up waste heat at moisture exhausting port.

The technical scheme that its technical problem that will solve the utility model adopts is: drying box and hot-blast stove are complete two independent parts, be provided with the hydrofuge case in the centre of two drying boxes, the utility model at least by about two drying boxes integrated, end is provided with balanced hot bellows about the drying box of the left and right sides respectively, be provided with the waste heat recovery case at the top of hydrofuge case, described waste heat returns ashamed case, be by constituting with wide ` square hydrofuge case of drying box and the tubular heat exchanger that is arranged in this case, the bottom of waste heat recovery case and hydrofuge case connect, the tubular heat exchanger front end is new wind suction inlet, there is an air collecting box rear end, this case end is connected with the air inlet of centrifugal blower, the centrifugal blower air outlet is connected with the air inlet of hot-blast stove, and the waste heat recovery box top is opened wide, and is moisture exhausting port.The beneficial effects of the utility model are, have effectively changed the mode that hot blast flows, and make windage little, can select relatively little blower fan for use, not only economize on electricity but also dry the temperature inside the box are even, have improved dry mass, in the damp-heat air of discharging, regain quite a few heat energy, saved the energy.

Description of drawings:

Embodiment below in conjunction with accompanying drawing further specifies the utility model:

Fig. 1 is a front view of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Fig. 3 is the vertical view of Fig. 1.

The specific embodiment:

Referring to Fig. 1,2,3, among the figure, 1. left drying box, 2. right drying box, 3. left balanced hot bellows, 4. right balanced hot bellows, 5. hot-blast stove, 6. hot-blast outlet, 7. left hot blast efferent duct, 8. right hot blast efferent duct, 9. left hot-flow flue, 10. right hot-flow flue, 11. dividing plate, 12. waste heat recovery casees, 13. tubular heat exchangers, 14. new wind suction inlets, 15. centrifugal blower, 16. hydrofuge casees, 17. balanced fresh air inlets, 18. air collecting box, 19. airduct, 20. moisture exhausting ports, 21. hot-blast stove air inlet .22. centrifugal blower air inlets.

Left side drying box 1 and right drying box 2 are separately positioned on the left and right sides of hydrofuge case 16, left end at left drying box 1 is provided with balanced hot bellows 3, right-hand member at right drying box 2 is provided with balanced hot bellows 4, be provided with waste heat recovery case 12 at the top of hydrofuge case 16, described waste heat recovery case 12 is by constituting with wide ` rectangular box of drying box and the tubular heat exchanger 13 that is arranged in this case, waste heat recovery case 12 bottoms and hydrofuge case 16 connect, tubular heat exchanger 13 front ends are new wind suction inlets 14, there is an air collecting box 18 rear end, this case end is connected with the air inlet 22 of centrifugal blower 15 through airduct 19, centrifugal blower 15 air outlets are connected with the air inlet 21 of hot-blast stove 5, the waste heat recovery box top is opened wide and is moisture exhausting port 20, top at left drying box 1 and right drying box 2 is respectively equipped with, left side hot-flow flue 9 and right hot-flow flue 10, and be respectively equipped with left hot blast efferent duct 7, right hot blast efferent duct 8 thereafter.

Its hot air circulation principle of the utility model is, when starting running, hot-blast stove 5 starts from flow fan 15, new wind promptly sucks from new wind suction inlet 14, absorbed the waste heat that hydrofuge case 16 is discharged through tubular heat exchanger 13, suck centrifugal blower 15 through air collecting box 18 and airduct 19, blast the hot-blast stove heating through this blower fan again, enter left hot blast efferent duct 7 respectively through hot-blast outlet 6 then, right hot blast efferent duct 8, then enter left hot-flow flue 9 and right hot-flow flue 10 and arrive left balanced hot bellows 3 and right hot blast equalizing box 4 respectively, balanced fresh air inlet 17 on dividing plate 11 imports in the drying boxes among the material, after carrying out dry run, hot blast carries a certain amount of water vapour and enters hydrofuge case 16, pass through shell and tube heat exchanger 13 then after, the moisture exhausting port 20 from waste heat recovery case 12 tops enters atmosphere.
