Description

[0002] Defoamers, also known as antifoaming agents, are additives used to inhibit the generation of foam or eliminate existing foam. Defoamers are generally made by mixing and reacting multiple ingredients. The raw materials used in their manufacture are generally in the form of solid (sucrose and lard, etc.), oil (silicone oil) and solution (ethylene glycol). During manufacturing, the various ingredients need to be reacted and mixed under certain conditions. In order to ensure the final quality of the defoamer, it is necessary to filter the raw materials after mixing to separate the particulate matter that has not fully reacted.

The two racks 103 are respectively meshed with the two gears 102, and the racks 103 drive the gears 102 to rotate, thereby driving the scraping frames 101 to rotate.

[0042] It also includes a limiting cover 11 , which is fixedly connected to the two rotating plates 62 , and the two sides of the limiting cover 11 are tightly fitted with the inner wall of the inner shell 2 , and the limiting cover 11 is used to limit the raw material on the filter screen 64 .

[0043] Initially, gear 102 and rack 103 are meshed, and the horizontal movement of hollow square tube 65 drives the scraper frame 101 to move horizontally, and the horizontal movement of scraper frame 101 drives the gear 102 to move horizontally. Under the action of rack 103, gear 102 will rotate, and the rotation of gear 102 drives the scraper frame 101 to rotate. The hollow square tube 65 moves in the opposite direction to drive the scraper frame 101 to move in the opposite direction, and the reverse movement of scraper frame 101 drives the gear 102 to move in the opposite direction. Under the action of rack 103, gear 102 will rotate in the opposite direction, and the reverse rotation of gear 102 drives the scraper frame 101 to rotate in the opposite direction. Through the above operation, it is easy to scrape away the accumulated particulate matter, reduce the probability of accumulation of unreacted particulate matter and slowing down the flow rate of raw materials, and further improve the filtration efficiency.

[0044] The limiting cover 11 can limit the raw materials dropped onto the filter screen 64, thereby reducing the probability of the raw materials adhering to and remaining everywhere.
