Abstract
The invention relates to a paint filtering device with an alarm function, wherein a cylindrical shell with an inner ring welded on the lower part of the inner wall is in threaded connection with a groove-shaped end cover, a filter screen bracket provided with a filter screen is welded on a base plate of the end cover, the filter screen is tightly pressed on the lower part of the inner ring of the shell through an annular elastic body arranged between the shell and the end cover, and a pressure sensor connected with an external alarm is arranged on the shell. The effective filtering area is adjusted by changing the height of the shell and the diameter of the cylinder, so that the production requirement of the coated steel plate is met. The surface area of the filter screen arranged in the filter screen is large, and even if impurities are accumulated on the side surface, the upper part of the filter screen can still be filtered. When the pressure increases, the pressure sensor drives the alarm to give an alarm, so that the problem is timely treated, the problem of paint splashing caused by the collapse of the filter screen is avoided, the floating color phenomenon generated in a paint tray in the production process of a coated steel plate is improved, and the surface quality of the coated plate is improved.
Description
Technical field
The invention belongs to cold-strip steel coating process equipment field, relate in particular to a kind of device that the used colour-wash of cold rolling coated steel sheet is filtered.
Background technology
Coating directly is driven in batea through pipeline by paint feeding pump by charging basket in the production process of cold rolling color painted steel strip, batea has overfall, part coating is through being coated with the roller transfer of coating to the operation belt steel surface, another part then is back in the bucket through overflow pipe by overfall, and circulation has constituted paint circulation system and so forth.The coating type that color painted steel strip uses is more, and common have a plurality of kinds such as fluorocarbon coating, conventional polyester coating, high durable polyester and silicon modified coating, the diluent and the solvent of middle use be the extremely active chemical agent of chemical property.Because coating material production, transportation, stir, have bad luck, link such as use, be subjected to pollution in various degree inevitably, especially in the application production process of coated steel sheet.Simultaneously, solvent in the coating and diluent all cause corrosion and aging to the pump housing and pipeline, seal gasket to some extent, enter in the coating thereby some impurity on the pipeline or the pump housing or the broken end of dissolved gum pad are washed away.If above-mentioned these impurity without effective filtration, will be coated to the color painted steel strip surface by being coated with the machine system, and then cause the blemish of filming, can't satisfy user's quality requirement.
Existing coating induction system is taked to roll filtration in the measure that the port of export of coating pipeline is simply helped to prick filter screen, because the sectional area of pipeline is less, makes the effective filtration area of filter screen can not do very greatly.Will occur like this causing pipeline port of export coating pressure to increase on foot, when serious even filter screen takes place collapse out, also can produce sometimes and splash owing to impurity blocks filter screen.If can not in time find, will cause the colored steel behind the coating mass defect to occur, even lead to parking stopping production accident, therefore not only cause the serious waste of raw material and coating, and meaningless having increased clean manpower and the time that is coated with machine and batea, and what influence was produced carries out smoothly.
Chinese patent application numbers 2006200493762 provides a kind of " filter that is used for the silicon steel coat system ", its filtering bodies is a cylindrical shell, the joint that can be connected with pipeline is equipped with the bottom in top at cylindrical shell, the upper side of cylindrical shell has the pipeline inlet, the lower side of cylindrical shell has the discharge of pipes mouth, on the middle hypomere inwall of cylindrical shell the oblique draw-in groove that runs through cylindrical shell is housed, oblique draw-in groove direction is along the lower pipeline floss hole, and screen pack is housed in the draw-in groove.Though this device is simple in structure, and is easy to operate, can clean filter at any time, reduced the obstruction of coat system pipeline.But, since this filter still to exist sectional area little, pile up more for a long time when impurity, occur impurity easily and block filter screen and cause the coating not smooth problem that flows, though can clear up, need increase manually and the time, even have influence on ordinary production.
Summary of the invention
The object of the present invention is to provide a kind of actual needs that can produce according to coated steel sheet, adjust the effective filtration area and the various impurity that filter out in the coating of screen pack, strengthen the homogeneity of paint viscosity, improve the clad plate surface quality, and have the coating filtering device of warning function.
For this reason, the technical solution that the present invention taked is:
A kind of coating filtering device with warning function comprises housing, screen pack and short tube, it is characterized in that, contains end cap, filter screen bracket, pressure sensor, alarm and elastic washer; The upper end is connected to short tube, lower ending opening, inwall bottom and is welded with the cylindrical housings of inner ring and is threaded with the flute profile end cap employing that connects short tube down, be provided with elastic washer between housing lower edge and the end cap chassis, the filter screen bracket of screen pack is installed in welding on the end cap chassis, and the pressure sensor that connects with the external alert device is installed on the housing.
Described screen pack be by be installed in annular elastomeric between housing and the end cap be pressed on the housing inner ring below; Annular elastomeric is the material of coating resistant solvent.
Described pressure sensor openend is provided with elastic sealing film, is filled with pressure transmission medium in the elastic sealing film; Pressure transmission medium is a paint solvent.
Described pressure sensor is installed on the housing outer wall.
Because filter of the present invention can be adjusted the effective filtration area of this device by changing the size of housing height and body diameter, thereby can adapt to the needs that coated steel sheet is produced.In screen pack upper surface and the circumferential section established the therefore corresponding filter area that increased, and behind side accumulation impurity, top still can be filtered is arranged entirely.When impurity accumulates to a certain degree, certainly will build-up of pressure increase, reach certain numerical value after, pressure sensor will drive alarm and be reported to the police, and make it can access timely processing, avoid screen pack to collapse opening the coating that the causes problem of splashing.And the shell of this filter is divided into housing and end cap two parts, backs out screw thread and just two parts can be separated, and the impurity of screen pack and accumulation is cleared up, and the impurity burden is big, can reduce clearing times.Because filter filters out the various impurity in the coating effectively, alleviated the stirring problem of coating to a certain extent, the corresponding uniformity consistency that strengthens paint viscosity, improve the flooding phenomenon that produces in the batea in the coated steel sheet production process simultaneously, for preventing that the surperficial color spot that defective such as coated steel sheet surface foul line and loose colour cause has good effect, thereby improve the surface quality of clad plate.
