Silk is located at clip surrounding, and the two screw thread is connected, and described feeding pipe is located at pipe support inside center, and it is connected with clip close-fitting,
Described sucker is located at pipe support both sides port, and the two glue is even connected, and described vavuum pump is located at pipe support right center, the two
Screw thread is connected, and described suction pipe is located on the left of pipe support inside center, and it is connected with vavuum pump screw thread.
Further, port is additionally provided with guiding set on the left of described suction pipe, and the two glue is even connected.
Further, port is additionally provided with filter screen on the right side of described feeding pipe, and the two glue is even connected.
Further, changeover valve is additionally provided with described pipe support outer wall top center, the two is weldingly connected.
Further, described pipe support outer wall top left side is additionally provided with flowmeter, and the two screw thread is connected.
Further, surrounding is additionally provided with some controllable valves at the top of described sucker, and the two is movably connected.
Compared with prior art, this automatic vacuum feeding device, only Raw material pail and chemical industry need to be placed in when using by pipe support
Between bucket, then by the liquid outlet of two barrels of suction cup sealed, then by vavuum pump and suction pipe the evacuating air in chemical barrel is formed
Vacuum environment, using atmospheric pressure principle, the raw material in Raw material pail enters chemical barrel, the stream of pipe support top left side by feeding pipe
Scale, which can be monitored, takes liquid value, changeover valve need to be only closed when it is completed, then open the controllable valve release of surrounding at the top of sucker
Sucker, the fixed form of feeding pipe is held out against by the lock screw of clip surrounding, when needing cleaning feeding pipe, only
The guiding set of port on the left of lock screw, suction pipe, which need to be unclamped, can strengthen the pull of vacuum raising efficiency of falling liquid, feeding pipe
The filter screen of right side port can carry out filtering to raw material prevents feeding blockage, and the structure function is powerful, utilizes air pressure principle
Complete sealing and take liquid, it is to avoid the traditional method of falling liquid raw material, which is leaked, to be polluted and waste.

Embodiment
Hereinafter, a variety of specific details are elaborated, to provide the saturating of the concept to constituting described embodiment basis
It is thorough to understand.However, it will be apparent to those skilled in the art that described embodiment can be in these no specific details
In it is some or all in the case of put into practice.In other cases, well-known process step is not specifically described.
As shown in Figure 1, Figure 2, Figure 3 shows, including work top 1, Raw material pail 2, chemical barrel 3, pipe support 4, clip 5, lock screw
6th, feeding pipe 7, sucker 8, vavuum pump 9, suction pipe 10, guiding set 101, filter screen 701, changeover valve 702, flowmeter 703, controllable gas
Mouth 801, pipe support 4 is located at the top of Raw material pail 2, and clip 5 is located at the inwall of pipe support 4, and it is several annulus, and the two is weldingly connected, lock
Tight screw 6 is located at the surrounding of clip 5, and the two screw thread is connected, and feeding pipe 7 is located at the inside center of pipe support 4, itself and the close-fitting phase of clip 5
Even, sucker 8 is located at the both sides port of pipe support 4, and the two glue is even connected, and vavuum pump 9 is located at the right center of pipe support 4, the two screw thread
It is connected, suction pipe 10 is located at the left side inside center of pipe support 4, and it is connected with the screw thread of vavuum pump 9, and the left side port of suction pipe 10 is additionally provided with
Guiding set 101, the two glue is even connected, and the right side port of feeding pipe 7 is additionally provided with filter screen 701, and the two glue is even connected, the outer wall of pipe support 4
Changeover valve 702 is additionally provided with top center, the two is weldingly connected, the outer wall top left side of pipe support 4 is additionally provided with flowmeter 703, two
Person's screw thread is connected, and the top surrounding of sucker 8 is additionally provided with some controllable valves 801, and the two is movably connected, this automatic vacuum feeding dress
Put, pipe support 4 need to be only placed in when using between Raw material pail 2 and chemical barrel 3, then two barrels of liquid outlet is sealed by sucker 8, then lead to
Vavuum pump 9 and suction pipe 10 are crossed by the evacuating air formation vacuum environment in chemical barrel 3, using atmospheric pressure principle, in Raw material pail 2
Raw material by feeding pipe 7 enter chemical barrel 3, the flowmeter 703 of the top left side of pipe support 4, which can be monitored, takes liquid value, when it is completed
Only changeover valve 702 need to be closed, then open the controllable valve 801 of the top surrounding of sucker 8 unclamp sucker 8, feeding pipe 7 is consolidated
Determining mode is held out against by the lock screw 6 of the surrounding of clip 5, when needing cleaning feeding pipe 7, only need to unclamp lock screw 6
, the guiding of the left side port of suction pipe 10, which covers 101, can strengthen the pull of vacuum raising efficiency of falling liquid, the right side port of feeding pipe 7
The filter screen 701 at place can carry out filtering to raw material prevents feeding pipe 7 from blocking.
The present invention is not limited to above-mentioned specific embodiment, one of ordinary skill in the art from above-mentioned design,
Without performing creative labour, a variety of conversion made are within the scope of the present invention.
