Specific embodiment
In order to make those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with attached drawing pair
The utility model is further detailed.
As shown in Figure 1, a kind of material provided by the embodiment of the utility model pumps automatic exhaust device, including batch can 1, the material
The bottom of tank 1 is communicated with discharge pipe 2, and bottom valve 3, material pump 4 and first check-valve 5 are disposed on the discharge pipe 2,
The conducting direction of the first check-valve 5 is consistent with the conveying direction of material pump 4, further includes exhaust pipe 6, the exhaust pipe
The one end in road 6 is connected on the discharge pipe 2 between the material pump 4 and first check-valve 5, the other end of the exhaust pipe 6
It is connected to the batch can 1；Lift check valve 7, the conducting direction of the lift check valve 7 are provided on the exhaust pipe 6
It is opposite with the conveying direction of material pump 4；The installation of the lift check valve 7 is configured as: flap can be fallen by gravity
Under.
Specifically, batch can 1 is all kinds of tanks equipped with liquid material, such as storage tank, agitator tank, bottom are connected with discharging
Pipeline 2 has been sequentially arranged bottom valve 3, material pump 4 and first check-valve 5, bottom valve 3 along the direction of material flow on discharge pipe 2
For controlling the opening and closing of discharge pipe 2, material pump 4 is used to provide power, and the feed liquid of batch can 1 is defeated along discharge pipe 2
It sees off, first check-valve 5 is check valve, the preferably check-valves of lift, is used to prevent the feed liquid for transferring to eminence from existing
It flows back under gravity, batch can 1, discharge pipe 2, bottom valve 3, material pump 4 and first check-valve 5 etc. are the prior art, are not repeated.
An exhaust pipe 6 is arranged in the present embodiment, is arranged a lift check valve 7 on exhaust pipe 6, and the one of exhaust pipe 6
End is respectively communicated with the middle and upper part or top of batch can 1, the discharge port of other end connection material pump 4, the specific can be that being connected to material
On pipeline between the discharge port of pump 4, the feed inlet of first check-valve 5 or material pump 4 and first check-valve 5, the present embodiment
In, the circulating direction of first check-valve 5 is identical as material pump 4, and the feed liquid that so material pump 4 pumps out can pass through first check-valve
It 5 and can not flow back, but the circulating direction of lift check valve 7 and material 4 contraries of pump, i.e., the feed liquid that material pump 4 pumps out can not pass through
Lift check valve 7, such feed liquid will not flow back into batch can 1 via exhaust pipe 6.The core innovative point of the present embodiment exists
In the installation of lift check valve 7 is configured as: flap can be fallen by gravity.In general, the valve of lift check valve 7
Valve is driven by the fluid of the conveying in it to open and close, if but by its it is vertical place or the placement of near vertical,
Due to gravity, flap can nature whereabouts.More preferred, the interlude of exhaust pipe 6 is arranged vertically, the lift
Check-valves 7 realizes that flap is fallen by gravity by being arranged on interlude.Lift various sizes of for different model stops
Valve 7 is returned, flap is different by the angle that gravity can be fallen, and can carry out verifying acquisition by simply testing, will
The lift check valve 7 of experiment target is arranged in different tilt angles and is passed through fluid, and observation can be obtained by situation
The result whether flap thoroughly falls.In the present embodiment, when needing to be vented, bottom valve 3, the big content of starting materials in batch can 1 are opened
Under gravity, the gas of discharge pipe 2 squeezes driving by slow to pass through and expect pump 4, and passes through material and pump 4 by lift-type check
Valve 7 flows back into batch can 1, is finally discharged by the exhaust outlet of batch can 1, it is critical that the driving force of gas is original at this time
The gravity of material, material pump 4 will not be damaged by slow transitting through material pump 4, simultaneously as lift check valve 7 is in upside-down mounting shape
State, gravity force flap to fall, and gas can pass through, that is, realize and inversely pass through check valve.And after material pump 4 is opened, expecting
Under the impact of liquid, flap overcomes gravity to be again switched off lift check valve 7 by feed liquid driving, realizes non-return.The same check valve,
By vertical upside-down mounting, the reversible by passing through with irreversible under high-speed case of slow situation is realized.
Material provided by the embodiment of the utility model pumps automatic exhaust device, when needing to be vented, by the weight of material in batch can 1
Power forces air to be slowly automatically again introduced into batch can 1 by material pump 4 and lift check valve 7, is given by the evacuation port of batch can 1
With discharge, lift check valve 7 carries out one-way non-return by gravity, realizes the reverse movement of gas when exhaust using the characteristic,
One-way non-return effect when not influencing normally to convey again simultaneously.
In another embodiment provided by the utility model, it is preferred that the above-mentioned material pumps automatic exhaust device, described
Ball valve 8 is additionally provided on exhaust pipe 6, the ball valve 8 is set between the lift check valve 7 and material pump 4, starting
Ball valve 8 can be closed before material pump 4, is more insured at this time.It is furthermore preferred that above-mentioned material pumps automatic exhaust device, the material pump 4
For centrifugal pump.
In further embodiment provided by the utility model, it is preferred that be located at 3 He of bottom valve on the discharge pipe 2
