Abstract
The utility model relates to a damp discharge and air return device in tobacco parching house, comprising an air duct (1), an exhaust fan (2) connected with the exit end of the air duct (1) and a damp discharge air door (3) connected with the air outlet of the exhaust fan; a plurality of air inlet holes (4) in rows are positioned on the pipe wall of the air duct (1); the air duct (1) is annular or crisscross shaped. The utility model evenly absorbs the damp and hot blast from various directions in the parching house, maintains the balance of the temperature and humidity and keeps even damp discharge or forms even hot-blast circulation in the tobacco parching house, thereby ensures the quality of the parched tobacco. The utility model has the advantages of simple structure and high operation efficiency.
Description
Technical field
The utility model belongs to the tobacco curing barn technical field, mainly is the device that is used for the tobacco curing barn humidity discharging.
Background technology
Existing tobacco curing barn, its ventilation dewetting mode mostly is the humidity discharging of natural airflow ascending manner, promptly relies on the window at barn top to get rid of the interior moisture of barn.In barn, fire tube at first heats the cold air of barn bottom, and the cold air expanded by heating forms thermal current and rises.Thermal current has been passed to tobacco leaf to the heat of self on the one hand in uphill process, temperature descends; On the other hand, tobacco leaf is heated, water evaporates, and the moisture of tobacco leaf is accepted and held to hot-air, increased airborne water content.Because the temperature of rising thermal current descends, moisture increases, and density increases, and the thermal current of rising changes the cold airflow that opposite direction is sunk into.Cold airflow has met the thermal current that rises below again in the process of sedimentation, the intersection at the barn middle part carries out the exchange of moisture and heat, and keeps relative stable state, and this has just formed cold air mass.Because the existence of cold air mass makes that the barn bottom temp is the highest, relative humidity is minimum; Barn middle part temperature is minimum, the relative humidity maximum; The humiture on barn top is placed in the middle.Because the lack of uniformity of temperature, humidity if the hydrofuge of barn and circulating air are inhomogeneous, just will cause the quality of tobacco in the bake process low in the barn.
In recent years, numerous producers has carried out various forms of transformations to old barn, the also newly-built different barns of many forms, hot air circulating system and robot control system(RCS) have been increased to improve humidity discharging, improve baking quality of tobacco, but the moisture discharge device that is adopted mostly is in the barn top window and connects air draught mechanism, this humidity discharging mode can form uneven flow field in barn, especially form the dead angle of air current flow in four corners of barn easily, cause the inhomogeneous of temperature and humidity.Also the someone has designed at " Y " of barn top mounting strap fresh air inlet shape airduct moisture discharge device, but because the asymmetry of " Y " shape airduct structure, be arranged in the comparatively regular barn of four sides wall structure and can not absorb moisture or hot blast equably, make that still temperature and humidity is inhomogeneous in the barn from the barn all directions.Thereby cause the not bright-coloured and generation dust tobacco leaf of tobacco leaf color in the barn baking, thereby quality of tobacco is descended, bring enormous economic loss to the tobacco grower.
Summary of the invention
The purpose of this utility model provides a kind of moisture or hot blast of can absorbing equably from all directions of barn for the deficiency that solves above-mentioned prior art existence just, the harmony that keeps temperature and humidity in the barn, make the interior evenly hydrofuge of barn or evenly form hot air circulation, to guarantee the quality of baking tobacco leaves, and the humidity discharging air-returning device that is applied to tobacco curing barn simple in structure, that operational efficiency is high.
The purpose of this utility model is achieved by the following technical solution.
A kind of humidity discharging air-returning device that is applied to tobacco curing barn, this device comprise airduct, are connected in the air exhauster and the humidity discharging air door that is connected with the air exhauster air outlet of wind tube outlet end, offer fresh air inlet in a row on the tube wall of airduct.Described airduct is air loop duct or cross airduct
Air loop duct described in the utility model is annular or square annular or oval ring; The fresh air inlet of on the tube wall of airduct, offering be opened in airduct the side or above; Between air exhauster air outlet and humidity discharging air door, be provided with the passage that leads to barn circulation airduct.
The utility model is installed on barn top, and when the needs humidity discharging, air exhauster starts, and the moisture in the barn is drawn in the airduct fast, equably by the fresh air inlet that is opened on the air loop duct, and the air door of humidity discharging is simultaneously opened, and moisture is discharged in the atmosphere fast.And when needing hot blast circulation time in barn, close the humidity discharging air door, start air exhauster, by the fresh air inlet on the airduct hot blast in the barn is drawn in the air loop duct equably, the hot blast of extracting out is led to the circulation airduct of barn, make hot blast enter barn again by the passage that is arranged between air exhauster air outlet and the humidity discharging air door, finish the hot air circulation of barn, thereby in an inner uniform flow field, the baking quality of raising tobacco leaf, and the utilization ratio of raising heat energy of forming of barn.Set airduct is symmetrical structure substantially, can be corresponding with the peripheral metope of barn, and make airduct can balancedly suck moisture or hot blast in the barn.Air loop duct of the present utility model can be made into the ring pipe of different shape as required, selects for use conveniently.Fresh air inlet is opened in the side of air loop duct or toply can effectively avoids steam to enter in the air loop duct.
The utility model can make the even hydrofuge of barn and form even hot air circulation, forms uniform hot blast flow field in barn, has guaranteed the uniformity of temperature and humidity, thereby the quality of tobacco of baking is improved.
Further set forth content of the present utility model below in conjunction with Figure of description.
