The invention can solve the problems of easy blockage of the paint filter screen and low filtering efficiency.
Description
Technical Field
The invention relates to the technical field of oil filtration, in particular to a filter for paint.
Background
Paint is a viscous oily pigment which is generally used for covering the surface of an object for protection, decoration, marking and other special purposes; in the production process of paint, all make paint pass through filtration equipment under the pressurization, and the process of impurity detach wherein, consequently need have the paint filter, current paint filter is including the jar body of dress paint, jar body upper portion has seted up the oil inlet, jar body lower part has seted up the oil-out, be provided with the filter screen between oil inlet and oil-out, paint filters through the filter screen under pressure and self weight effect, this kind of filter has because paint is the thick form and has viscidity to cause the filter screen to block up easily, the problem that filtration efficiency is low.
Disclosure of Invention
The invention aims to solve the technical problem of providing a paint filter, which can solve the problems of easy blockage of a paint filter screen and low filtering efficiency.
In order to solve the problems, the technical scheme adopted by the invention is as follows: the paint filter comprises a shell and a sealing cover arranged on the shell, wherein the shell is internally divided into a first cavity and a second cavity through a filter element, the shell is internally provided with an oil inlet communicated with the first cavity and an oil outlet connected with the second cavity, the paint filter comprises an outer shell and an inner shell, a sprayer controlled by an electromagnetic valve is arranged between the outer shell and the inner shell and penetrates through a nozzle of the inner shell, the sprayer of the filter element faces towards a nozzle of the inner shell, the inner side of the first cavity is provided with a pressure sensor, and the pressure sensor is electrically connected with the electromagnetic valve through a controller.
In the above technical solution, a more specific technical solution may also be: an oil inlet of the oil sprayer is communicated with the first cavity, and a sewage draining outlet is formed in the lower portion of the first cavity.
Due to the adoption of the technical scheme, compared with the prior art, the invention has the following beneficial effects:
1. because be provided with pressure sensor and the shower nozzle through solenoid valve control in the first cavity, when the filter core of first cavity one side blockked up, will produce pressure in the first cavity, when pressure reached pressure sensor's predetermined value, pressure sensor makes the sprayer spray pressure oil to the filter core through solenoid valve and controller and dashes the bottom of first cavity down with the plug on the filter core, avoids the filter screen to be blockked up by the greasy dirt, has improved filterable speed and efficiency.
2. Because the bottom layer of the first cavity is provided with the sewage draining outlet, sewage can be drained regularly.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The invention will be further described in detail with reference to the following examples:
the paint filter shown in fig. 1 comprises a shell and a sealing cover 1 arranged on the shell, wherein a filter element 10 is arranged in the shell, the inner cavity of the shell is divided into a first cavity 3a and a second cavity 3b by the filter element 10, the shell is provided with an oil inlet 2 communicated with the first cavity 3a and an oil outlet 9 connected with the second cavity 3b, and the lower part of the first cavity 3a is provided with a sewage outlet 8; the shell is provided with an outer shell 11 and an inner shell 3, an oil sprayer 7 controlled by an electromagnetic valve 6 is installed on the outer wall of the inner shell 3 corresponding to the first cavity 3a, a spray head of the oil sprayer 7 penetrates through the inner shell 3, a spray opening of the spray head faces to the filter element 10, and an oil inlet 7a of the oil sprayer 7 is communicated with the first cavity 3 a; a pressure sensor 4 is connected to a side wall of the first chamber 3a, and the pressure sensor 4 is electrically connected to a solenoid valve 6 via a controller 5.
During operation, when the filter core of first cavity one side blockked up, will produce pressure in the first cavity, when pressure reached pressure sensor's predetermined value, pressure sensor made the sprayer through solenoid valve and controller to the filter core jet pressure oil with the bottom of the jam filth on the filter core by the first cavity of wash down, avoided the filter screen to be blockked up by the greasy dirt to through the drain that first cavity bottom set up, periodic blowdown has improved filterable speed and efficiency.
Claims (2)
