Description

An external circulation water filtration device for producing microcapsule suspension

Technical Field

The utility model belongs to the technical field of filtration, and in particular relates to an external circulation water filtration device for producing microcapsule suspensions.

Background Art

Microcapsule suspension is a new type of pesticide formulation. Microcapsule suspension pesticide refers to a pesticide formulation that uses natural or synthetic polymer materials to form a core-shell structure micro-container, encapsulates the pesticide, and suspends it in water. A circulating water filter is a filter that directly intercepts impurities in the water, removes suspended matter and particulate matter in the water, reduces turbidity, purifies water quality, reduces system dirt, algae, rust, etc., to purify water quality and recycle water for reuse. Water enters the self-cleaning filter body from the water inlet. Due to the intelligent design, the system can automatically identify the degree of impurity deposition and send a signal to the sewage valve to automatically discharge sewage.

For example, the patent with publication number CN213760761U discloses an external circulation water filtration device for producing microcapsule suspensions, including a shell, the top and bottom of the shell are respectively connected with an upper cover and a lower cover by bolts, and the upper cover, the lower cover and the interior of the shell are combined to form a closed filter chamber, the bottom of the lower cover is connected with a sewage pipe and a water inlet pipe, and a valve is provided on the sewage pipe, a water outlet pipe is connected to one side wall of the shell, a motor is fixed to the top of the upper cover through a bracket, and a rotating shaft 1 is fixedly connected to the output end of the motor. The utility model is provided with a filter plate, which first roughly filters the circulating water entering the device, and filters large particles in the circulating water under the filter plate, thereby increasing the number of filtration stages, alleviating the working pressure of an original filter screen, and avoiding the problem that the original filter plate is easily blocked, thereby extending its service life and improving the working efficiency of the device.

The existing external circulation water filtration device for producing microcapsule suspension generally requires a motor to drive a scraper to scrape and clean the filter cartridge when in use. However, the filter cartridge needs to be cleaned regularly, which is cumbersome. In view of this, we propose an external circulation water filtration device for producing microcapsule suspension.
