Abstract
A kind of adjustable grain store ventilating duct, it is characterised in that: it includes being machined with some passages and the ventilation duct of home position observation window on the tube wall being vertically arranged, and is lifted on the intraluminal regulating piston of ventilation duct by winch；Described regulating piston is made up of piston cage, the rubber pneumatic bag that is arranged in piston cage；It is positioned at the air inlet mouth of pipe bottom described rubber pneumatic bag to be connected with source of the gas by air inlet pipe；Stretch out bottom described ventilation duct at the bottom of storehouse, be connected with blower fan.
Description
Technical field
This utility model relates to a kind of vertical grain store ventilation, adjustable grain store ventilating duct of cooling of being suitable for, particularly
Long-term storage field, Li Pu storehouse.
Background technology
Mostly current Li Pu storehouse is the roll-over of grain week, few with ventilating system.With the storehouse of ventilating system, its ventage
System design unreasonable, mainly have following some: ruling on 1 altitude mixture control steel wire rope and measure, inaccurate, labelling is preferably lost；2
Piston starting point is forbidden；3 are difficult to hold with rubber pneumatic bag piston pump pressure, or insufficient pressure, or just air bag are filled quick-fried.
Summary of the invention
The purpose of this utility model provides a kind of adjustable just for the weak point in the presence of above-mentioned prior art
Grain store ventilating duct.This is adjustable, and grain store ventilating duct is suitable for vertical grain store ventilation, cooling, and duct bottom is stretched out at the bottom of storehouse, with
Blower fan is connected, and determines installation radical as required.Particularly application profit Pu steel silo long-term storage.
The purpose of this utility model can be realized by following technique measures:
Adjustable grain store ventilating duct of the present utility model includes being machined with on the tube wall being vertically arranged some passages and former
The ventilation duct of position observation window, is lifted on the intraluminal regulating piston of ventilation duct by winch；Described regulating piston is by piston cage, peace
The rubber pneumatic bag composition being contained in piston cage；It is positioned at the air inlet mouth of pipe bottom described rubber pneumatic bag to be connected with source of the gas by air inlet pipe
Logical；Stretch out bottom described ventilation duct at the bottom of storehouse, be connected with blower fan；Described ventilation duct determines installation radical as required.
This utility model is provided with the height computer that the pull rope with described winch matches on ventilation duct pedestal.Institute
The bottom dead center position stating regulating piston is corresponding with home position observation window position, to confirm piston starting point.
Rubber pneumatic bag described in this utility model is placed on and is made up of in piston cage upper plate, lower plate and vertical rod, prevents air bag
Quick-fried by filling, needed for equilibrium air pressure, and reduction gas shutoff pressure.
Operation principle of the present utility model is as follows:
When needs ventilate to silo, first from observation port, confirm that piston in situ, according to grain layer height in silo, uses winch
Pulling piston, the frictional force of winch cable drives rolling counters forward roller, and piston lifting height is read by enumerator.Arrive and need
After wanting height, being inflated in rubber bag tank by trachea, piston cage prevents air bag from bursting, and equilibrium air pressure, adapts to wider pressure model
Enclose.Then starting blower fan air blast, air is gone to surrounding ease through grain layer by consent in draught tube walls, cooling of drying.When grain layer height
When changing, being exitted by rubber pneumatic bag, adjust height, (described regulation job demand is after closing blower fan to repeat aforementioned process
Carry out again).
The beneficial effects of the utility model are as follows:
1 arranges enumerator display height；
2 set home position observation window, to confirm piston starting point；
3 design piston cages prevent air bag from bursting, equilibrium air pressure, it is possible to decrease operating air pressure.

Detailed description of the invention
This utility model embodiment one:
As shown in Figure 1, 2, if adjustable grain store ventilating duct of the present utility model includes being machined with on the tube wall being vertically arranged
The ventilation duct 1 of dry passage and home position observation window 5, is lifted on the intraluminal regulating piston of ventilation duct by winch 4；Described regulation
Piston is made up of piston cage 2, the rubber pneumatic bag 3 that is arranged in piston cage 2；It is positioned at the air inlet mouth of pipe bottom described rubber pneumatic bag 3
It is connected with source of the gas by air inlet pipe 7；Stretch out at the bottom of storehouse bottom described ventilation duct 1, be connected with blower fan；Described ventilation duct is according to need
Installation radical to be determined.
This utility model is provided with the height computer that the pull rope with described winch 4 matches on ventilation duct 1 pedestal
6.The bottom dead center position of described regulating piston is corresponding with home position observation window 5 position, to confirm piston starting point.
Rubber pneumatic bag 3 described in this utility model is placed on and is constituted piston cage by upper plate 8, lower plate 9 and vertical rod 10 (4)
In 2, prevent air bag from being filled quick-fried, the gas shutoff pressure needed for equilibrium air pressure, and reduction.
