Production equipment for formaldehyde-free leather auxiliary agent and production process for formaldehyde-free leather auxiliary agent

Abstract

The invention discloses production equipment for a formaldehyde-free leather auxiliary agent and a production process for the formaldehyde-free leather auxiliary agent. The production equipment comprises a base, wherein the top of the base is fixedly provided with a mounting frame; the top of the base is fixedly provided with a stirring tank; the stirring tank comprises a feeding pipe and a discharging pipe; the discharging pipe is fixedly provided with a discharging valve; a stirring shaft is arranged in and rotatably connected with the stirring tank; a plurality of stirring blades are fixedly mounted on the stirring shaft; a driving motor is fixedly mounted on the mounting frame; the driving end of the driving motor is fixedly connected with the top end of the stirring shaft; a plurality of nozzles are fixedly mounted on the inner top wall of the stirring tank at equal intervals; a connecting pipe is fixedly mounted on the spray head; and an opening allowing the connecting pipe to penetrate through is formed in the top of the stirring tank. The invention relates to the technical field of production and preparation of leather auxiliary agents, and the production equipment is simple in structure, convenient to operate, convenient to clean stirring equipment, capable of uniformly distributing powder and beneficial to production of the auxiliary agent.

Description

technical field [0001] The invention relates to the technical field of production and preparation of leather auxiliary agents, in particular to a production equipment and a production process of formaldehyde-free leather auxiliary agents. Background technique [0002] Leather auxiliaries refer to the chemicals needed in the whole process of making leather from raw animal hides. In the processes of dyeing, fatliquoring, and finishing, it has the functions of wetting, diffusing, emulsifying, auxiliary tanning, color fixing, anti-dyeing, and anti-mildew. Softeners, pickling agents, tanning agents, leather dyes, leather additives, fatliquor and finishing agents, etc. In the modern leather industry, various auxiliaries are used at each stage, although the amount varies. Large, but because of its special properties different from other chemical materials, and its use can not only improve the quality and performance of leather products, but also simplify the production process, sh...

Problems solved by technology

[0005] However, the equipment still has the following problems: the mixing tank cannot clean itself after stirring, resulting in that the inner wall of the mixing tank cannot be cleaned in time, which directly affects the subsequent storage and use of the mixing tank, and it is not easy to use the powder directly. Wetting, not easy to disperse, easy to form agglomerates and other defects, for this reason, we propose a production equipment for formaldehyde-free leather auxiliaries to solve the above problems
