Embodiment
A kind of preparation of liquid oxygen includes as shown in figures 1 to 6 air pump 1, air inlet pipe 2, Rose Box 3, sliding rail with air filter
4, sliding block 5, movable plate 6, link block 7, fixed plate 8, PET cotton filter screen 9, HEPA filter screen 10, screen frame 11, active carbon
12, mounting plate 13, motor 14, gear 15, rack gear 16 and escape pipe 17；Escape pipe 17 is fixed in 3 one end of Rose Box, air inlet pipe 2
It is fixed in 3 other end of Rose Box, and air inlet pipe 2 is connected to air pump 1；Two sliding rails 4,6 both ends of movable plate are connected at the top of Rose Box 3
It is slidably connected by sliding block 5 with sliding rail 4；Fixed plate 8 is connect by link block 7 with 6 bottom of movable plate, PET cotton filter screen,
HEPA filter screen 10 and screen frame 11 are successively removably connect with 8 bottom of fixed plate in the horizontal direction, in screen frame 11
It is placed with active carbon 12；Mounting plate 13 is fixed in 4 top of sliding rail, and motor 14 is fixed in 13 top side of mounting plate；Gear 15 with
The transmission connection of 14 output end of motor, rack gear 16 is fixed in 6 top of movable plate, and is sequentially connected through mounting plate 13 and gear 15.
Firstly, air is pumped into Rose Box 3 by booster air pump 1 by air inlet pipe 2；Air successively passes through PET in Rose Box 3
The filtering of cotton filter screen, HEPA filter screen 10 and active carbon 12 passes through escape pipe 17 after having reached the standard for preparing liquid oxygen
Flow into processing district.
When being needed replacing after the 12 long-time use of PET cotton filter screen, HEPA filter screen 10 and active carbon, control electricity
The operating band moving gear 15 of machine 14 operates clockwise, since gear 15 and rack gear 16 are sequentially connected, so transporting upwards with carry-over bar 16
It is dynamic, and rack gear 16 drives connecting plate to move upwards by sliding block 5 along sliding rail 4 so that be fixed in the fixed plate 8 of connecting plate bottom to
Upper movement, after PET cotton filter screen, HEPA filter screen 10 and screen frame 11 remove Rose Box 3, control motor 14 stops fortune
Turn, then can easily replace PET cotton filter screen, HEPA filter screen 10 and active carbon 12, facilitate worker operation, improves
Working efficiency.
Wherein, as shown in Figures 2 and 3, which further includes having sample can 19, piston 20, adopting
Sample pipe 21, T shape connecting rod 22, guide sleeve 24 and the first inserted link 25；Sample can 19 is fixed in 3 top of Rose Box close to the one of escape pipe 17
Side, sampling pipe 21 are fixed in a upper lateral part of the sample can 19 close to escape pipe 17；T shape connecting rod 22 is living through 19 top of sample can
Plug 20 is fixed in 22 bottom of T shape connecting rod, and cooperates with the inserting of gas outlet 18 being provided at the top of Rose Box 3；Guide sleeve 24, which is fixed in, to be adopted
19 top side of sample tank, the first inserted link 25 are slidably connected with guide sleeve 24, and the first jack 23 being provided with 22 top of T shape connecting rod is inserted
Assembly is closed.
Since the long-time use of PET cotton filter screen, HEPA filter screen 10 and active carbon 12 may cause filtering effect
Fruit is deteriorated, so want whether the filtered air of periodic detection meets production standard, moving the first inserted link 25 at this time makes itself and the
One jack 23 is detached from, and pulls T shape connecting rod 22 then up, and band piston 20, which moves upwards, opens gas outlet 18, filtered
Air is discharged into sample can 19, and when piston 20 is located on sampling pipe 21, filtered air is flowed out by sampling pipe 21, worker
It is detected by collecting this portion of air.
After sampling, T shape connecting rod 22 is moved down, so that piston 20 blocks gas outlet 18, is avoided filtered
The case where air is revealed, corresponding first inserted link 25 of this first jack of thing 23, the first inserted link 25 is inserted into the first jack 23,
Can be fixed by T shape connecting rod 22 and piston 20, prevent piston 20 from being opened.
Wherein, as shown in Figure 4 and Figure 5, which further includes having connecting rod 26,29 and of elastic component
Second inserted link 30；6 top both ends of movable plate are connected with connecting rod 26, and the second jack 27 is provided in connecting rod 26；Mounting plate
13 two sides are provided with through-hole 28, and 13 both ends of mounting plate pass through 29 the second inserted link of connector 30 of elastic component, and the second inserted link 30 passes through
13 end of mounting plate is worn to be connected to through-hole 28.
After PET cotton filter screen, HEPA filter screen 10 and screen frame 11 are removed Rose Box 3, worker is carried out more at this time
When changing operation, worker is located at 6 lower section of movable plate, and the situations such as 14 failure of motor cause unexpected fall of movable plate 6 to injure by a crashing object in order to prevent
Worker, so when movable plate 6 moves upwards, after the insertion through-hole 28 of connecting rod 26 touches the second inserted link 30, due to connecting rod
26 tops are inclined-plane, and 30 end of the second inserted link is arc-shaped, so the second inserted link 30 is ejected through-hole 28 by connecting rod 26, when even
After corresponding second inserted link 30 of the second jack 27 on extension bar 26, the second inserted link 30 is inserted into the second jack under the action of elastic component 29
In 27, so the safety of operation can be improved by the fixed movable plate 6 of connecting rod 26.
Wherein, as shown in fig. 6,6 bottom of movable plate is fixed in gasket 31；Gasket 31 by fixed plate 8 and Rose Box 3 it
Between gap blocking, further improve leakproofness.
Wherein, as shown in fig. 6, being equipped with check valve 32 in air inlet pipe 2 and escape pipe 17；It avoids from air factory air inlet pipe 2
It flows back in escape pipe 17, ensure that the air in Rose Box 3 is discharged along escape pipe 17 always.
Using technical solution of the present invention or those skilled in the art under the inspiration of technical solution of the present invention, if
Similar technical solution is counted out, and reaches above-mentioned technical effect, is to fall into protection scope of the present invention.
