Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to set forth in detail.
Fig. 1 is the worm reduction gear of the embodiment of the invention and the schematic representation that is connected of axle; Fig. 2 is the electronic airtight valve ventilation plant structural representation of the embodiment of the invention.The anticorrosion electronic airtight ventilation plant of the embodiment of the invention, it contains valve plate 2, valve body 3, EPDM sealer 10, axle 8, worm-gear speed reducer 7, explosion-proof closed enclosure 4, electric control box 9, protective net 1, circle connects round interface 5 and clockwise and anticlockwise axial-flow fan special 6 is formed; Valve plate 2 is formed by the mold pressing of PP engineering plastics, and intensity is high, any surface finish, slyness; In wear stainless steel rotatingshaft 8, valve body 3 is to be formed by the mold pressing of PP engineering plastics, beautiful shape, liner EPDM one sealer 10; The PP engineering plastics have stronger acidproof, alkaline resistance properties, and are anti-aging, corrosion-resistant; Axle 8 adopts the 316L stainless steel material to make, and is provided with four roads " O " type sealing, guarantees tightness; Join worm-gear speed reducer 7, security level is IP55, joins the water proof and dust proof motor, and explosion-proof plastics closed enclosure 4 guarantees that motor and spacing control section are not corroded by phosphine gas.Power control line is used explosion-proof pipe joint locking, and integral body has explosion prevention function.Clockwise and anticlockwise axial-flow blower power is 0.55kw, and ventilation is 8000m
3/ h, airtight valve can bear 0.2MP pressure, and tightness is high, satisfies the stifling airtight requirement in warehouse fully.Fig. 3 is the schematic representation of the electric control box of the embodiment of the invention.
The electronic airtight ventilation plant technical parameter performance table of LPDD type is following:
The electronic airtight valve ventilation plant of the present invention working principle: when needing to ventilate in the storehouse; At first start the speed reducer motor, slowly open valve plate, when treating that valve plate becomes 90 ° with valve body; Automatically stop; This moment, valve was opened fully, and then started axial-flow blower, and axial-flow blower can just change also and can reverse as required.Airtight valve and axial-flow blower have adopted interlock, and valve is not opened fully, and axial-flow blower can't start, and axial-flow blower not throttle down can't be closed.This function has been avoided when air door is in less state, and high velocity air and draught fan impeller friction cause the generation of deflagration phenomenon.
(1) the low blast ventilation operating mode of lowering the temperature slowly.
When adopting low blast to lower the temperature the ventilation of ventilation needs slowly in the storehouse, at first open Cang Xiabutongfengkou, the more electronic airtight valve in top is opened; Be opened to 90 at valve plate and stop when spending, axial-flow blower starts, and axial-flow blower can be just to be changeed also and can reverse; Be forced air blast and draw-out type air draught, after the ventilation certain hour reaches the cooling requirement, close blower fan by stop button; After blower fan stops, closing airtight valve again.Be applicable to that also the grain layer is thicker, the occasion that resistance is bigger is ventilated, and in grain heap wind net, the air input end is by storehouse leg space ventilation machine forced draft, and the air output terminal can improve drafting efficiency greatly by 4 the ventilator negative pressure air draught of top, storehouse.
(2) the diffusing gas operating mode of hydrogen phosphide recirculation fumigation rear venting.
After the stifling airtight time reached set time or Expected Results, gas can loose.When needing exhausting in the storehouse, press the axial-flow blower invert button, valve plate is opened to 90 when spending, and axial-flow blower starts, and is effective need stop the time in ventilation, presses stop button, and blower fan stops, and closes airtight valve again.
Though the utility model with preferred embodiment openly as above; But embodiment and accompanying drawing are not to be used for limiting the utility model; Anyly be familiar with this art; In spirit that does not break away from the utility model and scope, work as certainly and can do various variations or retouching, but same within the protection domain of the utility model.Therefore the protection domain of the utility model should with the application claim was defined is as the criterion.
