Description

A kind of Pneumatic mechanical type liquid distribution trough

[technical field]

The utility model relates to a kind of Pneumatic mechanical type liquid distribution troughs, are transported using the gas of the distributor institute in-line Dynamic driving vane structure rotation, rotary motion of the rotary motion by gear pair transmitting for shaft end distributor, high-speed rotating axis Inner wall of the pipe where this liquid medium from inlet tube is uniformly scattered to the distributor by end distributor, in inner wall of the pipe shape At corrosion liquid medium protective layer, to reduce the corrosion of pipeline where corrosive goods are verified.

[background technique]

In oil refining and chemical plant installations, due to containing corrosive substance in raw material, reacted in order to prevent in following process The corrosion leakage risk of Cheng Zhong, device and equipment, the liquid usually by a certain amount of with anticorrosive property inject reaction process In phase feed medium, play the role of neutralizing the corrosive substance in phase feed medium.Simultaneously higher in corrosion risk Position distributor is set, the inner wall of position pipeline where the liquid of the anticorrosive property of injection is evenly distributed in, in pipeline Inner wall forms corrosion liquid medium protective layer, to achieve the effect that the perishable position of protection.

However, refine oil the mode that straight tube filling is generallyd use with pipeline fluid injection in chemical plant installations at home at present, injection Pipeline where liquid is entered in the form of column or waterline, the direction of the gas flow of phase feed medium is in duct bottom later Gather, trickle, gas-liquid contact effect is very poor, effectively cannot form protective layer in inner wall of the pipe, is unable to reach injection protection and is situated between The technique purpose of matter.

And as the research to neutralization preservative deepens continuously, under the premise of smaller protection medium usage amount, benefit Reach maximum protecting effect with least protective agent, low discharge, high concentration protective agent injection mode under, how to make to protect Agent, which is efficiently mixed with phase feed medium, occurs neutralization reaction, while forming protective layer in inner wall of the pipe, for device section The operation that can be lowered consumption is of great significance to.

[utility model content]

Described in background technology to solve the problems, such as, the utility model devises a kind of Pneumatic mechanical type liquid distribution trough, Using the kinetic energy of the gas medium of high-speed motion in the pipeline of place, drive mechanism drives shaft end distributor high speed rotation, Liquid medium is set uniformly to scatter to inner wall of the pipe where the distributor, protective agent forms protective layer in inner wall of the pipe, to have Protective conduit is imitated, the risk of corrosion leakage is avoided.

To achieve the goals above, the utility model uses following design structure:

A kind of Pneumatic mechanical type liquid distribution trough, including outer inlet tube, interior inlet tube, shell, driving gear, driving shaft axis It holds, vane bar, vane main shaft, driving vane, distributor bearing, band distributor driven shaft and driven gear, in the shell Top is connected with outer inlet tube, interior inlet tube is provided on the shell of the outer inlet tube lower part, in the lower part of the shell Aperture is set, drive shaft bearing is installed, the drive shaft bearing with vane main shaft is concentric is socketed installation, in the vane main shaft Front end connects vane bar, in the front end of vane bar connection driving vane, in the rear end concentric locking collar of the vane main shaft Connect installation driving gear, the shell right side setting aperture install distributor bearing, the axis of the distributor bearing with The axis of drive shaft bearing is vertical, the distributor bearing be socketed installation with distributor driven shaft is concentric, be distributed in the band The rear end of device driven shaft is socketed installation driven gear with one heart, and the driving gear engages with driven gear, formed described in it is pneumatic Mechanical liquid distribution trough.

The Pneumatic mechanical type liquid distribution trough, the driving gear and driven gear are a pair of intermeshing cone tooth Wheel, axis are mutually perpendicular to.

The Pneumatic mechanical type liquid distribution trough, the driving vane quantity are 3-8, are being along with vane main shaft The circumference uniform distribution of axis.

The Pneumatic mechanical type liquid distribution trough, the front end with distributor driven shaft are provided with 5-10 shunting Hole, tap hole is in the front end of distributor driven shaft along the circumference uniform distribution of the axis with distributor driven shaft.

The Pneumatic mechanical type liquid distribution trough, the band distributor driven shaft are hollow core structures, inside it with one heart Inlet tube in installing.

The Pneumatic mechanical type liquid distribution trough, the gas medium driving driving vane of the high-speed motion, thus band Dynamic vane main shaft rotation.

The outer inlet tube carrys out liquid pipe line with outside and connect, and the type of attachment of screw thread or flange can be used.This reality simultaneously With it is novel can integral installation to place pipeline center position, general place and perishable position can be used.

Due to using above-mentioned design structure, the utility model is had the advantages that

1, overall structure is simple, and all parts are easy to process, convenient for whole assembly.

2, pneumatic structure is compact, and drive efficiency is high.

3, dispersion effect is good, and the protection medium of injection can efficiently and uniformly be scattered to inner wall of the pipe, and protective agent uses Ultrahigh in efficiency.

[specific embodiment]

By the following examples can detailed explanation the utility model, open the purpose of this utility model is intended to protect All technological improvements in the scope of the utility model.

A kind of Pneumatic mechanical type liquid distribution trough in conjunction with described in attached drawing 1, attached drawing 2, attached drawing 3, including it is outer inlet tube 1, interior Inlet tube 2, shell 3, driving gear 4, drive shaft bearing 5, vane bar 6, vane main shaft 7, driving vane 8, distributor bearing 9, Band distributor driven shaft 10, driven gear 11 and other accessories and attachment.

At work, Pneumatic mechanical type liquid distribution trough integral installation described in the utility model to place pipeline center position It sets, when the gas medium in pipeline flows through distributor, the gas medium driving vane 8 of high-speed motion drives 7 high speed of vane main shaft Rotation, rotary motion are transferred to band distributor driven shaft 10 by vane main shaft 7, driving gear 4 and driven gear 11.It comes from The liquid medium of outer inlet tube 1 reaches inside the distributor with distributor driven shaft 10 by interior inlet tube 2.Due to band distributor 10 high speed rotation of driven shaft, the liquid medium from interior inlet tube 2 can be moved circumferentially due to inertia, in the circle of distributor There are several apertures on circumferential surface, liquid medium scatters to surrounding along aperture.Axis with distributor driven shaft 10 and place pipeline Axis it is consistent, therefore scatter liquid medium can uniformly be ejected into inner wall of the pipe, inner wall of the pipe formed effective protection aquiclude, To achieve the effect that the perishable position of protection, avoid corrosive pipeline.Simultaneously equally distributed liquid medium also can in pipeline Neutralization reaction occurs for corrosive substance in gas phase media, avoid existing straight tube filling bring gas-liquid contact effect it is very poor, It cannot be effectively the problem of inner wall of the pipe forms protective layer.
