It is specifically a kind of for the organic molten of liquid crystal display panel manufacturing automatic double surface gluer the present invention relates to industrial technical fieldAgent recyclable device.
Background technique
Currently, in liquid crystal display panel manufacturing automatic double surface gluer, it is common practice to which the organic solvent being precipitated through PR glue is madeFor dangerous waste direct emission；The finely ground particles being mixed in production process in the organic solvent being precipitated through PR glue are again introduced into productionSystem is easy to produce the problems such as product quality is bad.
Existing common practice causes the organic solvent usage amount of automatic double surface gluer big, and the organic solvent after discharge is as dangerUseless processing, not only pollutes environment, but also keeps the production cost of the link high.It is few be suitble to the above feature be suitable for liquid crystalThe filtering type organic solvent recovery device of panel industry automatic double surface gluer.
Summary of the invention
The purpose of the present invention is to provide a kind of organic solvents for liquid crystal display panel manufacturing automatic double surface gluer to recycle dressIt sets, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme:
A kind of organic solvent recovery device for liquid crystal display panel manufacturing automatic double surface gluer, including automatic double surface gluer and main recycling storageTank, the main recycling storage tank end cap portions are reserved with compressed air with interface tube and organic solvent entry/exit interface；Main recycling bottom of storage tankReserve organic solvent discharge outlet in portion；And first level filtering device F1 is installed on main recycling storage tank, end storage tank is two sets, and one with oneThe organic solvent outlet of standby design, main recycling storage tank is connected with the entrance of end tank top by piping, end tank bottomOutlet piping be connected to automatic double surface gluer；And two-stage filter F2 is installed in end tanks portion, the bottom of automatic double surface gluer goes outFor mouth by the entrance of piping connection dry pump, the outlet of dry pump connects condenser, the outlet connection delivery pump of condenser, delivery pump toolThere are two delivery outlet, a delivery outlet connects the first level filtering device F1 on main recycling storage tank, another delivery outlet is directly to arrangePut mouth.
As further technical solution of the present invention: the main recycling storage tank side is equipped with the interface for observing liquid level.
As further technical solution of the present invention: being equipped with high liquid level sensor inside the condenser and low liquid level sensesDevice.
As further technical solution of the present invention: the main recycling tank inside is equipped with liquid level sensor.
As further technical solution of the present invention: the end tank inside is equipped with liquid level sensor.
As further technical solution of the present invention: the main storage tank and end tank inside, which are equipped with, prevents overflow notBecome rusty steel tank.
As further technical solution of the present invention: being equipped with leakage detection sensor in the stainless steel sink.
Compared with prior art, the beneficial effects of the present invention are: the present invention is used for liquid crystal display panel manufacturing automatic double surface gluerOrganic solvent recovery device can solve the direct waste discharge problem of liquid crystal display panel manufacturing automatic double surface gluer organic solvent, structureIt is simple and convenient to operate, guarantees that organic solvent is recycled from direct waste discharge, securely and reliably, reduce dangerous waste treating capacity.Recycling dressIt is compact to set whole design, area occupied is small, simple, convenient safety, and it is good that organic solvent recycles effect.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, completeSite preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based onEmbodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every otherEmbodiment shall fall within the protection scope of the present invention.
Embodiment 1: Fig. 1-3, a kind of organic solvent recycling dress for liquid crystal display panel manufacturing automatic double surface gluer are please referred toIt sets, including automatic double surface gluer and main recycling storage tank, the main recycling storage tank end cap portions are reserved with compressed air with interface tube and organicSolvent entry/exit interface；Main recycling tank bottom reserves organic solvent discharge outlet；Main recycling storage tank side is equipped with for observing liquid levelInterface, and first level filtering device F1 is installed on main recycling storage tank, for being recovered by filtration larger particles in solvent, end storageTank is two sets, the using and the reserved design, and the organic solvent outlet of main recycling storage tank passes through piping phase with the entrance of end tank topEven, the outlet piping of end tank bottom is connected to automatic double surface gluer；And two-stage filter F2 is installed in end tanks portion, it appliesFor the outlet at bottom of gluing equipment by the entrance of piping connection dry pump, the outlet of dry pump connects condenser, the outlet connection of condenserDelivery pump, for delivery pump tool there are two delivery outlet, a delivery outlet connects the first level filtering device F1 on main recycling storage tank, anotherDelivery outlet is direct emission mouth.Main recycling tank inside is equipped with liquid level sensor, and end tank inside is equipped with liquid level sensor, leads toThe liquid level sensor for being installed on main recycling storage tank and end storage tank is crossed, judges the reserves of organic solvent, when after recovery processingOrganic solvent reserves meet produce and use when, device automatically switches to recycling supply model；Otherwise automatically switch to direct confessionTo mode.High liquid level sensor and low liquid level sensor are equipped with inside condenser.
As shown in Figures 2 and 3, the course of work of the invention is as follows:
The organic solvent being precipitated after the coating of PR glue, is pumped into main recycling storage tank, reusing compressed air will be accurate by conveyingFiltered organic solvent is pressed into end storage tank, when automatic double surface gluer provides desired signal, by the organic solvent in the storage tank of endIt is sent into equipment designated position.
When in use, for recyclable device whether according to the liquid level of each storage tank internal solvent, recycling mould can be entered by judging automaticallyFormula.
It is in place of embodiment 2, with the difference of embodiment 1, may be produced in main storage tank, end storage tank, pneumatic control case etc.The position of raw organic solvent leakage, is mounted on the stainless steel sink for preventing overflow, and leakage detection is equipped in stainless steel sinkSensor, once there is a situation where organic solvents to leak, recyclable device is closed, and is automatically switched to organic solvent and is directly fed mouldFormula.Guarantee the safe and reliable operation of system with this.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er QieIn the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matterFrom the point of view of which point, the present embodiments are to be considered as illustrative and not restrictive, and the scope of the present invention is by appended powerBenefit requires rather than above description limits, it is intended that all by what is fallen within the meaning and scope of the equivalent elements of the claimsVariation is included within the present invention.Any reference signs in the claims should not be construed as limiting the involved claims.
