Technical Field

[0001] This utility model relates to the field of chemical equipment technology, and in particular to a reaction tank with highly dispersible feed. Background Technology

[0002] In chemical plants, reaction tanks are commonly used equipment for raw material reactions. Currently, the general situation of reaction tanks is that liquid reaction tanks often suffer from insufficient feed dispersion, leading to frequent product defects. The current feeding method is mainly top feeding, which causes the raw materials to fall onto the liquid surface, failing to disperse quickly and resulting in localized overfeeding. Utility Model Content

[0003] This invention addresses the technical problems in existing reaction tanks where top feeding makes it difficult to quickly disperse raw materials and causes excessive local feeding, by providing a reaction tank with highly dispersible feeding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A reaction vessel with highly dispersible feed includes: a tank body, an end cap, a bottom feed pipe, a motor, a stirring shaft, a first impeller, and a second impeller; The tank body is configured as a semi-enclosed structure with an open top; the end cap is fixed to the upper end of the tank body; the bottom feed pipe is located inside the tank body, and the outlet of the bottom feed pipe is located at the bottom of the tank body; The motor is mounted above the end cover, the stirring shaft is disposed inside the tank, and the stirring shaft is connected to the motor; The first blade and the second blade are mounted on the stirring shaft, with the first blade positioned above the second blade; the first blade is a ZCX three-bladed blade, and the second blade is a YCK propulsion blade.

[0005] Based on the above technical solution, the present invention can be further improved as follows.

[0006] Furthermore, the feed pipe is configured with an "L" shape, with a longitudinal section at the top and a transverse section at the bottom; the longitudinal section of the feed pipe is parallel to the side wall of the tank, and the transverse section of the feed pipe is parallel to the bottom of the tank; the outlet of the feed pipe faces the longitudinal central axis of the tank. The feed pipe is provided with at least two; multiple feed pipes are arranged symmetrically.

[0007] Furthermore, the second blade is disposed in the middle area enclosed by the transverse portions of the plurality of feed pipes.

[0013] Compared with the prior art, the reaction tank with high dispersibility feeding provided by this utility model has the following beneficial effects: This invention provides a highly dispersible feed reaction tank with a semi-enclosed structure with an open top. An end cap is fixed to the upper part of the tank. A bottom feed pipe is located inside the tank, with its outlet at the bottom.
