Description

Structure for preventing paper machine crossbeam from accumulating pulp

Technical Field

The utility model relates to a prevent long-pending structure of starching of paper machine crossbeam belongs to papermaking equipment technical field.

Background

Due to the structural design of the paper machine, the cross beam at the bottom layer of the paper machine stretches across the paper web, and in the operation process of the paper machine, water vapor mixed with fine fibers easily forms slurry accumulation on the cross beam, and the slurry accumulation can slide to the mesh surface of the forming net for a long time, so that broken holes are easily formed after the slurry accumulation falls, paper breakage is caused, and production is influenced. The utility model discloses a portion of net high pressure cleaner that application number is CN201820038868.4 forms during the use and sprays high-pressure water column to on the shaping net that is washd, reaches clean effect, and the cleaning unit can make a round trip at the uniform velocity on the installation crossbeam and remove, can carry out the net limit and wash and local washing to realize wasing the mesh of shaping net. But cannot clean the bottom cross beam of the paper machine. The cross beam stretches across the upper part of the bottom paper web, water vapor and fine fibers are easy to attach to the surface of the cross beam, and accumulated materials can be accumulated and slide to the paper web to cause hole breaking and paper breaking.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the utility model provides a prevent structure of long-pending thick liquid of paper machine crossbeam adds spray set for the crossbeam is whole, carries out the crossbeam and washes when changing the book, avoids the thick liquids accumulation, avoids the disconnected paper that the long-pending thick liquids problem of crossbeam caused.

Prevent long-pending structure of starching of paper machine crossbeam, including the crossbeam that is located the forming wire top, be equipped with in the both sides of crossbeam and spray the washing pipeline, spray the washing pipeline and arrange along the length direction of crossbeam, spray the washing pipeline and be equipped with the spout towards the crossbeam on the road.

A spraying cleaning pipeline is additionally arranged above the cross beam, the spraying cleaning cross beam is periodically opened, the attached fine fibers on the cross beam are cleaned, and paper breaking caused by accumulation and sliding is avoided.

Furthermore, the two sides of the cross beam are also provided with air blowing and drying pipelines which are arranged along the length direction of the cross beam, and the air blowing and drying pipelines are provided with nozzles facing the cross beam. After the spraying cleaning, the blowing and drying pipeline is started to accelerate the air drying of the cross beam.

Spray and wash the pipeline and dry pipeline of blowing all can rotate around axis separately, make and spray or the direction of blowing change to the increase sprays or air-dries the area, makes the obtaining of crossbeam furthest rinse, and the washing pipeline that sprays of one side can wash the pipeline of spraying of opposite side and dry pipeline of blowing, thereby avoids the pipeline sizing material that newly adds to pile up.

The end parts of the spraying cleaning pipeline and the blowing drying pipeline are connected with rockers, the ends of the rockers are provided with cranks, the rockers and the cranks are located outside the paper machine, and the spraying or blowing direction can be changed by manually shaking the rockers.

Preferably, the length direction of the rocker is 180 degrees with the nozzle direction, so that the orientation of the spray head of the pipeline in the paper machine can be conveniently and visually known, and the opposite direction of the rocker is the orientation of the spray head.

Preferably, the spraying cleaning pipeline and the blowing drying pipeline are both positioned above the two sides of the cross beam in an inclined manner.

Compared with the prior art, the utility model the beneficial effect who has is:

prevent the long-pending structure of starching of paper machine crossbeam, reasonable in design, the practicality is extremely strong.

1. The paper can be cleaned in time after pulp stacking, paper breaking caused by pulp stacking falling is avoided, the hidden danger of paper breaking is perfectly solved, and the operation efficiency of the paper machine and the product quality are improved;

2. the structure is simple, the cost investment is low, and the installation method is simple.
