Technical Field

The application relates to the technical field of metallurgy, in particular to a pneumatic lifting device for a sludge pipeline and a sludge treatment system.

Background

At present, most of sludge lifting devices in the domestic metallurgical industry adopt a screw pump, a slurry pump, a pneumatic lifter and the like, in a steelmaking water treatment system, the pneumatic lifting device is adopted for conveying precipitated sludge, compressed air is connected into a pneumatic lifter pipe, and then the lifting and conveying of the sludge are carried out through the pressure difference pulsation of a flexible valve of a sludge conveying pipe. The main equipment system comprises a sedimentation tank, a mud conveying pipe, a flexible valve and a pneumatic lifting device. The system has the following problems in the use process:

the pneumatic lifting device needs to be positioned at the straight pipe section, and because the backflow of the slurry can not be prevented, when the sludge conveying is stopped, part of sludge slurry can be poured into an air pipe of the pneumatic lifting device to form scale, and the air pipe can be blocked at intervals, so that the sludge conveying effect is influenced. The quick cut-off valve of the lifting device is affected by the returned sludge to scale, and the blocking and the failure of the valve body are caused by the blocking, so that the operation of the whole sludge system is affected.

Disclosure of Invention

An object of the application is to provide a mud pipeline air lifting device, it can improve the easy obstructed problem of scale deposit of current air lifting device.

Another object of the present application is to provide a sludge treatment system including the above sludge pipeline air-lifting device, which has all the characteristics of the sludge pipeline air-lifting device.

The embodiment of the application is realized as follows:

the embodiment of the application provides a sludge pipeline air-lift device, including device main part and compressed air pipe, compressed air pipe connect in the device main part, compressed air pipe inlet end is used for connecting the air supply, a part of compressed air pipe stretches into device main part and the end orientation of giving vent to anger the mud mouth of device main part, sludge pipeline air-lift device is still including preventing blockking up the structure, prevent blockking up the structure and include shutoff ball, shutoff support and locating part, the shutoff support includes macrostoma end and microcephaly end, macrostoma end with the end of giving vent to anger is connected, the shutoff ball float settle in microcephaly end just can the shutoff microcephaly end, the locating part connect in the shutoff support just can restrict the home range of shutoff ball.

The pneumatic lifting device of the sludge pipeline changes the caliber of the pipe orifice of the existing compressed air pipe through the plugging support, and plugs the small orifice end by the plugging ball, so that the small orifice end can be plugged rapidly when the sludge stops conveying, and the sludge slurry is prevented from flowing backwards into the compressed air pipe. Because the compressed air pipe can not be filled by the mud poured backwards, the scaling condition can be avoided, and the problem that the rapid cut-off valve is blocked due to the fact that the mud flows smoothly because of the unsmooth air flow in the subsequent work is avoided. The limiting piece can ensure that the sealing ball cannot leave the small opening end too much, so that the sealing ball can timely return to the small opening end and seal the small opening end when slurry stops conveying.

In addition, the pneumatic lifting device for the sludge pipeline provided by the embodiment of the application can also have the following additional technical characteristics:

in an alternative embodiment of the present application, the cross section of the plugging tray is frustum-shaped.

In the optional embodiment of this application, spacing passageway is constructed to the inboard of spacing portion, the shutoff ball can move in the spacing passageway, spacing passageway allows the gas flow, when compressed air pipe blows in gas, the shutoff ball is located the first position of spacing passageway, when compressed air pipe stops blowing, the shutoff ball is located the second position of spacing passageway just will the shutoff of osculum end.

By constructing the limiting channel, the moving path of the blocking ball is basically fixed, and the accidental state is not easy to occur in daily work.

In an alternative embodiment of the present application, the blocking channel is a vertical channel.

The vertical channel can make the switching time of shutoff ball between primary importance, second position shortest, when mud stops to carry, can block off the microcephaly fast end.

In an optional embodiment of the application, the connection position of the connecting part and the plugging tray is located at the connection position of the large opening end and the compressed air pipe.

When the welding device is used for processing, the welding can be carried out together, and the welding can be carried out at one position, so that the whole welding device can be distributed when external acting force is applied, and the fracture of the connecting position can be avoided.
