Hydrocarbon solution circulation filtering device

Abstract

The invention discloses a hydrocarbon solution circulation filtering device. The hydrocarbon solution circulation filtering device comprises a cleaning tank, a cylindrical filter, a particle concentration detection device, a circulation pump and a filtering assembly, wherein the cleaning tank is used for containing a hydrocarbon solution; the cylindrical filter is connected with an outlet of the cleaning tank, and is used for filtering the hydrocarbon solution; the particle concentration detection device is connected with an outlet of the cylindrical filter, and is used for detecting the content of particles in the primarily filtered hydrocarbon solution; the circulation pump is connected with the outlet of the cylindrical filter, and is used for pressurizing the primarily filtered hydrocarbon solution; the filtering assembly is connected with an outlet of the circulation pump and an inlet of the cleaning tank, and is used for filtering the hydrocarbon solution again. The hydrocarbon solution circulation filtering device has the advantage that by additionally arranging the particle concentration detection device in a hydrocarbon solution circulation filtering pipeline, the contentof particles in the cleaned and recycled hydrocarbon solution can be detected, and then the cleanliness of the hydrocarbon solution in the cleaning tank can be detected, so as to effectively maintainthe solution at the higher purity in the recycling process of the hydrocarbon solution.

Description

technical field [0001] The invention relates to the field of workpiece surface cleaning, in particular to a hydrocarbon solution circulating filter device. Background technique [0002] With the development of economy and technology, mechanical automation has achieved rapid development. At present, due to the high cleaning cost and unsatisfactory cleaning effect of ordinary spray cleaning on workpieces processed by mechanical automation, hydrocarbon solutions are usually used to remove grease, dust and other particles on the surface of workpieces in mechanical automation. As all walks of life have higher and higher requirements for the accuracy of spare parts, the requirements for the particle size of the cleaned workpiece surface are also higher and higher, because the hydrocarbon solution of the cleaned workpiece will be recycled and reused in the cleaning process , but the hydrocarbon solution is only filtered once during recovery and reuse, and the filtered hydrocarbon ...

At present, due to the high cleaning cost and unsatisfactory cleaning effect of ordinary spray cleaning on workpieces processed by mechanical automation, hydrocarbon solutions are usually used to remove grease and dust and other particles on the surface of workpieces in mechanical automation

As all walks of life have higher and higher requirements for the accuracy of spare parts, the requirements for the particle size of the cleaned workpiece surface are also higher and higher, because the hydrocarbon solution of the cleaned workpiece will be recycled and reused in the cleaning process , but the hydrocarbon solution is only filtered once during recovery and reuse, and the filtered hydrocarbon solution is returned to the hydrocarbon cleaning tank. Only by frequently changing the filter element in the circulation pipeline can the high The effect of purity, but in this way we cannot know the content of particle size in the cleaning solution. When high-precision cleaning is required, the effect of high-precision cleaning cannot be achieved if the content of particles in the cleaning agent is slightly high. It is difficult to control the surface of the workpiece after cleaning. Whether the particles are cleaned
