Description
Technical field
The utility model relates to the grain depot apparatus field, is specifically related to a kind of grain depot nitrogen gas recovering apparatus.
Background technology
Known composition of air is made up of 78% nitrogen, 21% oxygen and other impurity of %1; And grain depot need utilize when storing up grain nitrogen production equipment to produce high-purity nitrogen; Through the nitrogen transfer pipeline nitrogen is charged in the good warehouse of air-tightness; Make that nitrogen gas concn remains on higher level for a long time in the storehouse, form a low-oxygen environment that is unfavorable for foodstuff pest, growth of microorganism breeding, thus reach make foodstuff pest stop to endanger grain, can't growth and breeding until death by suffocation; Suppress the grain physiological respiration simultaneously, delay the effect of grain quality ageing, promptly nitrogen is separated through special media in nitrogen making machine by air.When system nitrogen warehouse is inflated, inflate according to the rules because of density unevenness and spare, carry out circulation with convector; Even basically when the warehouse nitrogen gas concn, discharge tail gas, because of inside and outside differential pressure; Need through convector or blower fan tail gas to be discharged by force, nitrogen concentration is higher than airborne ratio in the tail gas, and required special media is that comparison is expensive in system nitrogen process; If just the useless nitrogen in the warehouse obtains utilizing, can reach the purpose of economic environmental protection, energy-saving and emission-reduction.
The utility model content
The utility model technical problem to be solved is to provide a kind of special-purpose nitrogen gas recovering apparatus of grain depot of easy to use, energy-saving and emission-reduction.
The utility model technical problem to be solved adopts following technical scheme to realize:
A kind of grain depot nitrogen gas recovering apparatus; Comprise base and the body of being located at the base top; It is characterized in that: said body comprises the air channel piecing devices that directly are fixed on the base and is located at the air accumulator that piecing devices one side in air channel connects as one through pipeline configuration; Said air channel piecing devices end face opposite side is provided with four air channel air inlets, the top of said air accumulator be provided with outlet and connect tracheae, the bottom is provided with a negative pressure switch.
Said base also comprises four trundles that install the bottom and the manumotive armrest that is positioned at the base top.
Said manumotive armrest be welded on the side that iron sheet outside air accumulator is fixed together with rivet and is positioned at air accumulator.
The top of said air channel piecing devices also is provided with nitrogen gas concn monitoring mouth.
Also be welded with reinforcement between said air channel piecing devices and the air accumulator.
Said air accumulator set inside has cleaner.
During work, four air channel air inlets on the piecing devices of air channel and the air channel exhaust outlet on the warehouse are connected, the tracheae on the air accumulator is connected to the compressor of nitrogen making machine; Form an airtight pipeline, power source comes from nitrogen making machine, starts negative pressure switch; Make the nitrogen making machine air inlet form negative pressure; With the principle of the malleation formation pressure reduction that fills nitrogen warehouse air bag, make a gas distribution, Rose Box, make the useless nitrogen that fills the discharge of nitrogen warehouse obtain utilizing; And availability can improve about 9%, can reach the target of balanced each point concentration simultaneously without machine circulation.
The beneficial effect of the utility model is: the utility model novelty simple in structure; The riding position freedom is unrestricted, and maintaining is convenient, need not independent working power; The nitrogen resource is reclaimed fully, utilizes; Realization can be worked continuously, and has reduced the cost of system nitrogen to a great extent, economic environmental protection, energy-saving and emission-reduction.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with specific embodiment and diagram, further set forth the utility model.
As shown in Figure 1; A kind of grain depot nitrogen gas recovering apparatus; Comprise base 1 and the body 4 of being located at the base top; Body 4 comprises the air channel piecing devices 2 that directly are fixed on the base 1 and is located at the air accumulator 8 that piecing devices 2 one sides in air channel connect as one through pipeline configuration 5; Piecing devices 2 end face opposite sides in air channel are provided with four air channel air inlets 3, and the top of air accumulator 8 is provided with outlet and connects the negative pressure switch 12 that tracheae 7, bottom are provided with a diameter 80mm, and base 1 also comprises four trundles 11 installed the bottom and the manumotive armrest 6 that is positioned at the base top; Manumotive armrest 6 be welded on the side that iron sheet 10 usefulness rivets outside air accumulator are fixed together and are positioned at air accumulator 8; The top of air channel piecing devices 2 also is provided with nitrogen gas concn monitoring mouth 13, also is welded with reinforcement 9 between air channel piecing devices 2 and the air accumulator 8, and air accumulator 8 set inside have cleaner.
