Crylic acid adhesive reaction still bottom feeding device

The utility model relates to a crylic acid adhesive reaction still bottom feeding device which comprises a feeding pipeline arranged at the bottom of a reaction still and a feeding pump, wherein the feeding pump is connected with the feeding pipeline in series; a one-way valve is arranged in a pipeline at the joint of the feeding pipeline and the reaction still. The crylic acid adhesive reaction still bottom feeding device has the following advantages: a feeding hole is formed in the bottom of the reaction still and the feeding pump is used for feeding material to the bottom of the reaction still, so that the situation that the material enters the reaction still and has premature violent reaction is avoided, and the normal operation of a stirrer is not affected; the one-way valve in the feeding pipeline can prevent material backflow during feeding.
