Background technology
At present; Just towards the direction fast development of indoor stereo formula plantation, in indoor stereo formula implant system, the arrangement of culture medium of edible fungus is very intensive in the production of edible mushroom; In narrow and small relatively growth room, room air can't satisfy the oxygen demand of edible fungi growth.Therefore; Needing to be equipped with air exchange system is that edible fungi growth provides more oxygen; Like publication number is the gas filter system that the patent documentation of CN201783266U discloses a kind of solid growth edible fungi growth chamber, comprises air inlet and dividing plate, in the inboard of air inlet the coarse filtration web plate is set vertically; On dividing plate, be provided with fine filtering web plate and air input unit, the fine filtering web plate is and is horizontally disposed with; The distance on fine filtering web plate and roof, growth room is a 1.2-2 rice; The fine filtering web plate is made up of fine filtering cloth and screen holder, and the coarse filtration web plate is made up of the cheese cloth of framework and wavy setting; The air input unit is made up of blower fan and wind conveying pipe; Through coarse filtration web plate and twice filtration of fine filtering web plate; Effectively the airborne impurity of filtering guarantees that edible mushroom is not contaminated, and air-flow sees through the fine filtering web plate and evenly gets into lower floor planting edible mushroom district; Help the growth of edible mushroom, the fine filtering cloth of coarse filtration web plate is wavy effective filter area that increased that is provided with.But this technical scheme remains deficiency both ways, the one, receive stopping of culture medium of edible fungus rack for placing in the cultivating chamber, and its ventilation is inhomogeneous, and especially the air of middle and lower part is changed poor effect, influences the growth of edible mushroom; The 2nd, because of ventilation causes the change of cultivation indoor air temperature big, be unfavorable for edible fungi growth, also be unfavorable for energy savings.
Summary of the invention
The utility model provides the air exchange system of a kind of edible fungus industrial cultivation chamber, can realize that cultivating chamber evenly takes a breath, and improves scavenging efficiency, improves ventilation effect; Further purpose reduces the amplitude of variation that ventilation causes the cultivation indoor air temperature.
The technical scheme that the utility model adopts is: the air exchange system of a kind of edible fungus industrial cultivation chamber; Comprise between the cultivation that is separated into by a plate and ventilation between; Have between ventilation and lead to outdoor air inlet, the air inlet place is provided with screen pack, to getting into the assorted bacterium of air filtering between ventilation; Ventilation hole is set on the dividing plate, passage is provided for the air between ventilation gets between cultivation; Bottom between cultivation is provided with backwind tube, and backwind tube sucks air, and the heat exchanger entrance in tube connector is sent into air between ventilation; The outlet of heat exchanger connects air exhauster, and air exhauster is extracted air out outdoor.
During work; Air exhauster powers up work; Outdoor fresh air is sucked by air inlet; And through the assorted bacterium of filter screen elimination; Pass through heat exchanger immediately; Heat exchanger makes the air of its inside and outside of flowing through carry out heat exchange, and the fresh air temperature of flows outside is drawn close to the discharged air temperature of internal flow, to reduce energy loss; Fresh air gets between cultivation by the passage on the dividing plate subsequently, and even downwards diffusion is flowed; Original air is sucked by the bottom backwind tube between cultivation, and is inner through the heat exchanger that tube connector is sent between ventilation, carry out heat exchange with the outside fresh air of heat exchanger of flowing through after, pump to outdoor by air exhauster again.In scavenging period; Original air is sucked by the bottom backwind tube between cultivation; Fresh air is then sent into by the ventilation hole at top between cultivating, and between cultivating, forms uniform air flow from top to bottom, and fresh air can spread equably rapidly and flow to each corner between cultivation; Make scavenging efficiency high, effective.
Be uniformly distributed with suction hole on the above-mentioned backwind tube.Equally distributed suction hole can make the air draught zone of backwind tube more evenly broad, can make ventilation effect better.
Above-mentioned backwind tube is around around the bottom surface sections between cultivating.Around the bottom, the discharge efficient of original air was higher between the air draught area distribution of backwind tube was cultivated, and the diffusion effect of fresh air is more outstanding, and ventilation effect is better.
Place the wind-guiding net in the ventilation hole on the aforementioned barriers.The wind-guiding net can adopt common screen cloth, is beneficial to uniform air intake; Also can adopt the style net of tape guide plate, be beneficial to uniform air intake and between cultivating, spread in order all around and flow.
The utility model carries out air draught through the bottom that backwind tube is arranged between cultivation; Make that the scavenging efficiency between cultivating is high; It is effective to change wind, and utilizes heat exchanger that fresh air is carried out the temperature preliminary treatment, has reduced the temperature change amplitude of being brought because of ventilation between cultivating; Help reducing energy resource consumption, save production cost.
Embodiment
Below, be described further in conjunction with the embodiment of accompanying drawing the utility model.
Fig. 1 shows the embodiment of the air exchange system of a kind of edible fungus industrial cultivation chamber; Comprise between the cultivation that is separated into by a plate 11 1 and ventilation between 2; 2 have and lead to outdoor air inlet 21 between ventilation, and air inlet 21 places are provided with screen pack 22, filter assorted bacterium to getting between ventilation 2 fresh air; On the dividing plate 11 ventilation hole is set, places screen cloth 12 on the ventilation hole, 1 passage is provided between cultivating for the fresh airs in 2 between ventilation get into; 1 bottom is provided with backwind tube 13 between cultivation; Backwind tube 13 around between cultivating 1 around; And be uniformly distributed with suction hole 131 on it, backwind tube 13 sucks air, and the heat exchanger of air being sent between ventilation in 2 through tube connector 14 3 enters the mouth; The outlet of heat exchanger 3 connects air exhauster 31, and air exhauster 31 is extracted inhaled air out outdoor.
