Abstract
The invention discloses a PIPE coating device, which comprises a sealed container, wherein an air inlet pipe and a liquid outlet pipe are arranged on the sealed container, a filter is arranged on the liquid outlet pipe and a piezometer is also arranged on the liquid outlet pipe. The coating device is high in yield and the utilization rate of PI liquid is high.
Description
Technical field
The present invention relates to LCD production field, be specifically related to a kind of PI apparatus for coating.
Background technology
PI painting process is the indispensable operation of LCD industry; PI liquid required for coating will be carried on coating wheel; some plant equipment extracts PI liquid on coating wheel by corrosion protection pump; due to corrosion protection pump long-term work wearing and tearing; there is granule to be mixed in PI liquid, PI liquid can be made like this to pollute, directly affect yield; corrosion protection pump is rapid wear accessory simultaneously, and cost is high.Also have some producers by draught head PI hydraulic pressure on coating wheel, but preparing PI liquid can produce secondary pollution with conveyance conduit, gas-pressurized, container etc., make product be coated with after have bubble to produce, affect yield.PI liquid recovery utilization rate is low simultaneously, and discharge environmental pollution, does not conform to high efficiency production at present, energy-saving and emission-reduction theory.
Summary of the invention
The object of the invention is to: provide raising PI to be also coated with yield, and improve the PI apparatus for coating of PI utilization rate.
The present invention is achieved by the following technical solutions: a kind of PI apparatus for coating, comprising: airtight container, and described airtight container is provided with air inlet pipe and drain pipe, and described drain pipe is provided with filter; Described drain pipe is also provided with Pressure gauge.
As present invention further optimization scheme, described drain pipe is rubber tube.
As present invention further optimization scheme, during described drain pipe fluid, PI liquid first flows through filter, after flow through Pressure gauge.
As present invention further optimization scheme, described air inlet pipe is rubber tube.
As present invention further optimization scheme, described air inlet pipe is provided with pressure regulator valve.
The present invention has following beneficial effect:
1, apparatus for coating of the present invention, drain pipe is provided with filter, can filter out the impurity in PI liquid, improves the yield of painting process.
2, apparatus for coating of the present invention, air inlet pipe is provided with pressure regulator valve, and drain pipe is provided with Pressure gauge, can regulate and control PI liquid liquid outlet quantity and fluid speed accurately, improves PI utilization rate also, thus reduces costs, and reduces exhaust emission.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of PI apparatus for coating, comprising: airtight container 3, and described airtight container 3 is provided with air inlet pipe 1 and drain pipe 6, and described air inlet pipe 1 and air accumulator 6 are rubber tube.Described drain pipe 6 is provided with filter 4 and Pressure gauge 5, and described air inlet pipe 1 is provided with control valve 2.
PI liquid is gone out by drain pipe defeated 6 by draught head by this device, and the filter 4 on drain pipe 6 is clean by the various contaminant filters in PI liquid, improves coating yield.By the control valve 2 in air inlet pipe 1 and the Pressure gauge on drain pipe 6, can accurate management and control PI liquid liquid outlet quantity, improve the utilization rate of PI liquid, cost-saving.
