Material weighing and feeding device for metal working fluid production

Abstract

The invention relates to a material weighing and feeding device for metal working fluid production, which comprises an electronic platform scale, a raw material pump, a pipeline and the like. The electronic platform scale, a one-way valve and the raw material pump are respectively connected with a control electric box, and the control electric box is connected with an external power supply. A groove is arranged on the electronic platform scale, a raw material barrel is arranged in the groove, and a material pumping pipe is placed in the raw material barrel. A subtraction feeding method is adopted, material weighing and feeding equipment is additionally arranged, transformation of old equipment is omitted, the production process is simplified, labor is saved, and the working efficiency is improved. The one-way valve is installed on the material pumping pipe, when feeding is stopped, raw materials in the material pumping pipe cannot flow back into the raw material barrel, the raw materials remaining in the pipeline are counted in the feeding amount due to subtraction, the raw materials can be jacked into a stirring kettle when a next raw material is weighed, and due to the fact that all the raw materials are raw materials for producing machining liquid, even if the materials are mixed, the problem of pollution of the material pumping pipeline does not exist.

Description

technical field [0001] The invention relates to the field of metalworking fluid production, in particular to a weighing and feeding device for metalworking fluid production. Background technique [0002] Metalworking fluids are mainly liquids for metalworking, mainly for lubrication and cooling, and also for rust prevention and cleaning. General metalworking fluids include cutting fluids, cutting oils, emulsions, stamping oils, quenching agents, high temperature oils, extreme pressure cutting fluids, grinding fluids, antirust oils, cleaning agents, blackening agents, deep drawing oils, etc. Metalworking fluids are usually mixed and reacted by various chemical liquids to obtain a liquid with stable form. Only by reasonable procedures in the production process of metalworking fluids can high-quality products be obtained quickly and effectively. [0003] Since there are many kinds of raw materials in the metalworking fluid formula, and the formula unit is calculated by weight,...

Problems solved by technology

[0003] Since there are many kinds of raw materials in the metalworking fluid formula, and the formula unit is calculated by weight, it is impossible to use a volumetric pump to measure. The traditional production method is that the workers get the production process sheet, and according to the weight of each raw material on the list, the raw materials packed in 200L iron drums are used. The drum dumper is lifted up and down, poured into the raw material bucket placed on the electronic platform scale for weighing, and then the weighed raw materials are transported to the second-floor production platform by elevator, and put into the stirring tank from the feeding port in order. This method is more complicated and cumbersome, and inconvenient to operate;

[0004] In the new production line, the weighing module can be placed on the support feet of the stirring tank, and the raw materials can be fed in an additive way, which saves the transfer weighing tank, but if the raw materials are fed by pipelines and pumps, each raw material needs a separate feeding pipeline. To avoid cross-contamination of raw materials and residual raw materials in the pipeline entering the stirring tank, if it is manually added, the 200L raw material barrel needs to be transported to the second-floor platform, and there is no transfer during manual feeding. Once there is a mistake in excessive dosage, it is easy to produce waste products. Greatly increased the difficulty of work

Moreover, this additive feeding process is difficult to use in the transformation of old production lines, and the transformation cost is also high
