Vacuum self-suction type liquid drainage device

Technical Field

The utility model belongs to the technical field of the drainage, concretely relates to vacuum is from inhaling formula liquid drainage device.

Background

The vacuum drainage device is a common device in the chemical industry, has the function of draining fluid from a low position to a high position by utilizing a vacuum effect, and is particularly suitable for being used under the conditions that the pump filling amount is too large or a bottom valve is inconvenient to install. However, the vacuum drainage device has a closed structure, and when the vacuum drainage device is used for a long time or a fluid contains impurities, dirt is easily accumulated in the vacuum drainage device, and the vacuum drainage device is very difficult to clean.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects existing in the prior art, the utility model provides a vacuum self-suction liquid drainage device.

The utility model provides a vacuum self-suction liquid drainage device, which comprises a shell and a sealing cover detachably connected with the shell; a liquid inlet and a liquid outlet are arranged on the shell; an inner shell is also detachably arranged in the outer shell; the bottom of the inner shell is provided with a drainage hole, and the side wall of the inner shell is provided with an overflow channel; a liquid inlet pipe communicated with the liquid inlet is also arranged in the shell, and one end of the liquid inlet pipe, which is far away from the liquid inlet, extends upwards and is marked as an ascending section; the ascending section passes through the drainage hole from bottom to top and extends into the inner shell.

When the drainage device is used, the liquid inlet pipe connecting pipeline extends into the liquid level, the liquid outlet is usually positioned at the position below the shell, and the liquid outlet is connected with the inlet of the pump. If the pump chosen is a pump without self-priming function, which is often the case, a certain amount of liquid needs to be stored in the housing when the pump is started. After the pump starts, liquid in the shell is discharged gradually, and the liquid level descends gradually in the shell, forms the negative pressure to in continuously sucking the inner shell with liquid from the feed liquor pipe, liquid in the inner shell flows into the shell through overflow channel in, the debris that are mingled with in the liquid are held back in the inner shell. When the interior of the device needs to be cleaned, only the sealing cover needs to be opened, the inner shell is taken out, and sundries in the inner shell are poured out.

Further, the sealing cover is preferably arranged on the top of the shell in a covering mode; a support part is further arranged on the inner wall of the outer shell, and the inner shell is erected on the support part so as to be convenient to lift and take out the inner shell.

Furthermore, the supporting part is a convex ring fixedly arranged along the inner wall of the shell; the inner shell has a top plate, the edge of which exceeds the outer wall of the inner shell, and the edge of the top plate is erected on the supporting part.

Furthermore, a liquid supplementing port is also arranged on the side wall of the outer shell and is positioned above the inner shell; the top plate is provided with a liquid supplementing channel communicated with the inner cavity of the inner shell; the sealing cover is also provided with an air port. When the liquid level in the shell is too low, liquid can be added into the shell through the liquid supplementing port, and the added liquid flows downwards through the liquid supplementing channel to lift the liquid level in the shell. Meanwhile, the gas in the shell is discharged from the gas port, so that the liquid supplement is smoothly carried out.

Furthermore, the top plate is also connected with an air return pipe extending upwards, and the air return pipe is communicated with the inner cavity of the inner shell; the liquid supplementing channel is an arc-shaped hole; the liquid supplementing channel and the air return pipe are transversely staggered with the ascending section of the liquid inlet pipe, so that the ascending section is prevented from facing the liquid supplementing channel or the air return pipe. The position of the mouth of pipe of the gas return pipe is higher than the roof, and when the fluid infusion, the gas below the roof can be discharged through the gas return pipe fast, and the liquid of interpolation flows downwards through the fluid infusion passageway to carry out the fluid infusion fast.

Furthermore, a section of extension pipe is arranged upwards from the drainage hole in the inner shell; the rising section of the liquid inlet pipe is slidably inserted in the extension pipe. The outside of the extension pipe forms a chamber for accommodating sundries, so that the sundries can be prevented from falling off when the inner shell is lifted.

Further, the height of the extension pipe is preferably higher than the lowest position of the overflow passage.

Furthermore, the overflow channel is a group of sieve holes densely distributed on the side wall of the inner shell to filter out impurities.

Further, the sealing cover is pressed against the housing by a set of locking mechanisms to form a good seal.

Furthermore, the bottom of the shell is also provided with a sewage draining outlet. When the interior of the device is cleaned, the produced dirty liquid can be discharged from the sewage outlet.

Has the advantages that: compared with the prior art, the utility model provides a vacuum is from inhaling formula liquid drainage device, rational in infrastructure, convenient to use can upwards drain low-order liquid, debris in can the filtering liquid, and especially, the device's inside washs very conveniently.
