Description

Technical Field

[0001] The utility model relates to the technical field of cleaning devices for production equipment of organic chemical product alkyd resin, in particular to a cleaning device for alkyd resin filter plates. Background Art

[0002] In the production process of alkyd resin, vertical blade filters are generally used to filter resin. Since alkyd resin itself is viscous, it will change from a fluid to a solid state when it comes into contact with oxygen in the air in the filter kettle and under the action of a drying agent. After the resin is filtered, the filter plate is blown dry with air. During the resin reaction process, the viscosity of the resin increases and the adhesion becomes stronger, which can easily lead to the blockage of the filter screen of the filter plate in the subsequent filter. At this time, it needs to be cleaned before it can be used again. In the prior art, the cleaning of the alkyd resin filter plate is generally carried out by injecting a solvent into the filter to soak the filter plate for more than 24 hours, then starting a cycle to rinse more than ten times, and finally emptying the solvent to complete the cleaning of the alkyd resin filter plate. The defects of this cleaning method are that the processing time is long and the efficiency is low, and the service life of the filter plate is reduced. Utility Model Content
