Beating refining kettle for crude product of p-aminobenzoic acid

Abstract

The invention discloses a beating refining kettle for a crude product of p-aminobenzoic acid. The kettle comprises a supporting bottom plate; the upper surface of the supporting bottom plate is provided with two supporting plates, and a second beating outer shell is connected between the upper ends of the two supporting plates through bolts; and the middles of two ends of the interior of the second beating outer shell are each connected with a triangular support through a short shaft. According to the kettle disclosed by the invention, a second rotating shaft can be driven by a second motor torotate, a second beating column can be driven by the second rotating shaft to rotate, so that raw materials are subjected to longitudinal beating; and through connection of a sector gear and a corresponding connecting gear, one corresponding triangular support can be driven to swing, the triangular supports can drive material shifting columns and connecting rods to swing, so that raw materials located at the bottom surface of the interior of the second beating outer shell can be shifted, and material shifting is more convenient; and the beating refining kettle for the crude product of the p-aminobenzoic acid disclosed by the invention has a simple structure, is convenient to operate, and can perform beating from multiple directions, thereby making the beating more uniform and improving the beating efficiency.

Description

technical field [0001] The invention relates to the technical field of aminobenzoic acid production, in particular to a beating and refining kettle for crude p-aminobenzoic acid. Background technique [0002] P-aminobenzoic acid is widely used in the production of dyes such as reactive red M-80, reactive red M-10B, reactive red violet X-2R and the drug p-carboxybenzylamine. It has broad market prospects and improves the quality of p-aminobenzoic acid. During the production process The crude product should be beaten and refined. There are many problems in the conventional tank reactor, such as slow stirring will affect the beating effect, fast stirring will break the material crystallization, the appearance of the material after beating is uneven, and beating can only be done from one direction, so the beating efficiency Slow and inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing ...
