Abstract

The utility model relates to an enforcing wet removing natural air inlet type tobacco leaf curing barn with humiture automatic control. A blind type wet removing blower is mounted at the upper part outer side of a circulating air course built in one side gable of a stove, over against the gable air outlet, and a blind type air inlet is mounted at the middle and lower parts of the circulating air course and near the outside of the circulating fan. When the curing barn carries out intrinsic cycle, the wet removing blower stops working, and an air inlet blind is closed; when the curing barn carries out extrinsic cycle (wet removing), the wet removing blower works, and the air inlet blind is naturally opened depending on the inside and outside pressure difference at the same time.

Description

Force hydrofuge natural air inlet formula barn

Affiliated technical field

The utility model is the tobacco flue-curing facility of a kind of forced ventilation hot air circulation, humiture automatic control, has realized that especially complete automatically forcing to discharge is wet, can normally toast under situation about having a power failure simultaneously and is unlikely and influences baking quality of tobacco.

Background technology

At present, existing common standard gasification stream ascending manner barn is the main barn of China's baking tobacco leaves, account for more than 90% of barn total amount, after setting up humiture robot control system(RCS) and hot air circulation, its hydrofuge control mode has following several: 1. set up air intake blower fan at former barn stove indirect heat wind-tunnel, simultaneously set up wet-emitting blower (or hydrofuge turnover panel) in the barn skylight, air intake and air-out blower fan (or hydrofuge turnover panel) turn round simultaneously and carry out hydrofuge when needing hydrofuge.This hydrofuge control mode control point has 2, the equipment failure rate height, and improvement cost height (2 blower fan or 1 blower fan and 1 hydrofuge turnover panel), if wet-emitting blower is installed in barn top moisture exhausting port simultaneously, repair and maintenance inconvenience, the equipment back of breaking down is difficult for finding; 2. on the circulation canal of building on the barn stove gable on one side, set up the automatic control shutter outward near circulating fan, shutter is opened automatically when needing hydrofuge, relies on manually to open former barn hydrofuge skylight or former barn hydrofuge skylight and open always and carry out hydrofuge.This hydrofuge control mode automaticity low (can only open shutter automatically) does not have the hydrofuge of pressure meaning, and the shutter of automatic control simultaneously fault rate height is controlled dumb; 3. on the circulation canal of building on the barn stove gable on one side, set up automatic control outward near circulating fan and advance the hydrofuge air door, this door is opened automatically and has been blocked up circulation canal when needing hydrofuge, from this hydrofuge suitable for reading and the end opening air intake.This hydrofuge control mode hydrofuge is too fast, and humiture is fluctuated in the barn, influences baking quality of tobacco, and hydrofuge damper faults rate height is advanced in automatic control simultaneously, controls dumb; 4. on the circulation canal of building on the barn stove gable on one side, set up automatic control shutter or air intake blower fan outward by circulating fan, set up moisture exhausting port in barn body of wall appropriate location, the moisture exhausting port place is blocked up with the offset plate of constant weight, automatic control shutter or the automatic air intake of air intake blower fan work when needing hydrofuge, and moisture exhausting port place offset plate is opened voluntarily.If this hydrofuge control mode hydrofuge offset plate kicks the beam, open naturally easily when air is heated in the barn, influence the barn heat and moisture preserving, waste fuel; Overweight, can not open during hydrofuge.Therefore, all there is such-and-such deficiency in existing hydrofuge mode.

Summary of the invention

In order to overcome the deficiency of the existing automatic hydrofuge of barn, the utility model provides a kind of pressure hydrofuge natural air inlet formula barn, and this barn has overcome the deficiency of existing barn hydrofuge, under the minimum situation in hydrofuge control point, has really realized hydrofuge fully automatically.

The technical scheme that its technical problem that solves the utility model adopts is: the circulation air path upper outside of building at gable of stove is installed the venetian blind type wet-emitting blower over against the gable return air inlet, and venetian blind type air inlet (this shutter can only air intake can not air-out) is installed by the circulating fan outside in the circulation air path middle and lower part.Barn carries out interior circulation time, and wet-emitting blower quits work, air intake shutter closure; When barn carries out outer circulation (hydrofuge), wet-emitting blower work, the air intake shutter relies on the inner and outer air pressure difference to open naturally simultaneously.

The beneficial effects of the utility model are 1. to reduce the control point, reduction fault rate, prolongation service life of equipment, reduction power consumption, minimizing cost (the shutter price is lower), the raising of hydrofuge automaticity.2. humiture is stable in the barn, has avoided humiture phenomenon fluctuated to occur, and has reduced the cold air that enters barn, and tobacco leaf dehydrates stable, and the cured tobacco leaf quality improves.3. thermal efficiency height is controlled by wet-emitting blower fully because of the cool air that enters barn, has reduced unnecessary air dielectric waste, still has the portion of hot air to continue circulation when both making hydrofuge, does not directly discharge, and has reduced coal consumption.The humid air water capacity that moisture exhausting port is discharged is big, the humidity height, and hydrofuge is effective.4. barn good airproof performance, the heat and moisture preserving ability is strong.Mending air door because of venetian blind type can only air intake, can not air-out, and wet-emitting blower carries out hydrofuge as required, has effectively controlled intake, has reduced the loss of heat and moisture.5. venetian blind type is mended air door and can effectively be avoided " hydrofuge " phenomenon.6. be easy to after breaking down find, for ease of maintenaince.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the interior air motion schematic diagram of barn under wet-emitting blower and venetian blind type shutter installation site and the interior recurrent state.

Fig. 2 is that barn is at hydrofuge state downstream motion schematic diagram.

1. barn walls among the figure, 2. circulating fan, 3. wet-emitting blower, 4. venetian blind type air inlet, 5. circulation air path, 6. hot air circulation air-flow, 7. stove indirect heat wind-tunnel, 8. return air inlet in the barn.

The specific embodiment

In Fig. 1, when barn is in interior circulation time, the air-flow that circulating fan (2) produces enters barn through stove indirect heat wind-tunnel (7), and the tobacco leaf of flowing through carries out damp and hot exchange after return air inlet (8) once circulates by circulation canal, and so forth ...Wet-emitting blower this moment (3) shuts down, and venetian blind type air inlet (4) is closed.

In Fig. 2, when barn was in outer circulation (hydrofuge), a part of hot blast was proceeded interior circulation; Wet-emitting blower (3) rotates and carries out hydrofuge simultaneously, and venetian blind type air inlet (4) is opened air intake voluntarily naturally under the effect of inside and outside differential pressure, finish hydrofuge and so forth.

Claims

1. force hydrofuge natural air inlet formula tobacco curing barn for one kind, it is characterized in that: the upper outside of building circulation air path on gable of stove is installed the venetian blind type wet-emitting blower over against the gable return air inlet, the venetian blind type air inlet is installed by the circulating fan outside in the circulation air path middle and lower part, sets up hot air circulation blower and humiture robot control system(RCS) and realizes the automatic control of forced ventilation humiture.
