Abstract
The utility model discloses a forced ventilated system for a box-shaped hatching machine, which comprises an air-out mouth and a forced air-in mouth equipped with a fan; two air-in mouths are symmetrically arranged on the back board; a flow-guide cover is arranged inside the inner side. The air-out mouth is arranged on the top board of the box body; and an air-out canister is arranged on the outer side; the air-out canister is provided with a fan. The utility model has the advantages that: the air amount and the air-exchange ability are much larger, which is about 2-3 times larger than that of the prior art; the flow field is rational so as to be good for the uniformity for the temperature field inside the box body.
Description
Technical field
The utility model relates to hatch machine, particularly a kind of ventilating system of box type hatching machine.
Background technology
The ventilating system of existing box type hatching machine comprises big fan, air inlet 1 and air outlet 5, big fan is contained on the big fan column 10 that is positioned at the hatch machine middle part, air inlet 1 is positioned on the roof box 4, air outlet 5 is positioned on the casing backboard 9, owing to produce between the incubation period from thermal phenomenon, when temperature raise too soon, above-mentioned ventilating system can not be satisfied the demand, and generally will increase forced ventilation system.Existing forced ventilation system is to set up an air inlet 8 and forced draft fan 7 on casing backboard 9, as shown in Figure 2.Open fan 7 where necessary, increase intake from air inlet 8, flow out from air outlet 5 the circulation back in case.The shortcoming of this forced ventilation system is, intake is big inadequately, and the flow field of air intake is unreasonable, and portion of air can directly flow away from air outlet without circulation, thereby has influenced the uniformity of force ventilated effect and the temperature inside the box.
Summary of the invention
The purpose of this utility model provides a kind of forced ventilation system of box type hatching machine of better effects if.
The purpose of this utility model is achieved through the following technical solutions: a kind of forced ventilation system of box type hatching machine, comprise the air outlet and the forced air inlet mouth that are opened on the casing, on the forced air inlet mouth fan is housed, it is characterized in that the forced air inlet mouth is opened on the backboard, quantity is at least two, and kuppe is equipped with in the inboard of this air inlet, and air outlet is opened on the roof box, columnar chimney fan is equipped with in the outside of air outlet, and fan is housed in the chimney fan.
Said forced air inlet mouth and air outlet are symmetricly set on the left and right sides on casing backboard and the top board respectively in the such scheme.
Said kuppe is that profile is the kuppe that lateral opening is arranged of long flat box-like in the such scheme, and the angle that its opening sideline, back and casing vertical direction are installed is the 30-60 degree.
The advantage of this forced ventilation system is, one, because the quantity of forced air inlet mouth increases, and on air outlet, set up chimney fan and fan again, thereby increased intake and ventilation ability significantly, ventilation can thoroughly be carried out; Two,, make the flow field of air in the case be tending towards rationally helping the uniformity in temperature field because air inlet is equipped with kuppe; Three, because inlet and outlet can be equipped with the fan of adjustable power, the user can change force ventilated throughput easily according to environmental temperature and self-heating situation.
Description of drawings
Fig. 1 is the said box type hatching machine forced ventilation system of a utility model structural representation.
Fig. 2 is existing box type hatching machine forced ventilation system structural representation.
Fig. 3 is the kuppe structural representation of the said box type hatching machine forced ventilation system of the utility model.
Embodiment
Embodiment is the forced ventilation system that is used for EI19200 or EI16800 type box type hatching machine, the casing of this hatch machine has top board 4, backboard 9 and left side plate, big fan is equipped with in central authorities in the casing, big fan is contained on the column 10, air inlet 1 and symmetrical two air outlets 5 are arranged on the top board of casing, forced ventilation system comprises the symmetrical air inlet 8 that is opened on the casing backboard 9, be contained in fan 7 and the kuppe 7 that is contained in the air inlet inboard on the air inlet 8, and be contained in the chimney fan 3 in two air outlet 5 outsides and be contained in the interior fan 2 of this chimney fan, as shown in Figure 1.The distance of the center of air inlet 8 at the bottom of the case is 1300-1500mm, distance to box side is 300-350mm, the center of air outlet 5 is 1000-1100mm to the distance of backboard, distance to side plate is 750-850mm, the diameter of chimney fan is Φ 250-300mm, the fan capacity of air inlet and air outlet be the 500-800 cubic meter/hour.According to test, the ventilation ability maximum of this forced ventilation system can reach 2000 cubic metres/hour, is equivalent to 2.5 times of prior art.
Claims (3)
1, a kind of forced ventilation system of box type hatching machine, comprise the air outlet and the forced air inlet mouth that are opened on the casing, on the forced air inlet mouth fan is housed, it is characterized in that the forced air inlet mouth is opened on the backboard, quantity is at least two, and kuppe is equipped with in the inboard of this air inlet, and air outlet is opened on the roof box, columnar chimney fan is equipped with in the outside of air outlet, and fan is housed in the chimney fan.
