Spiral salt leaching machine for combined alkali production process

Abstract

The invention relates to the technical field of chemical machinery. The invention further discloses a spiral salt leaching machine for the combined alkali production process. The spiral salt leachingmachine includes a bottom plate, the left side of the top surface of the bottom plate is fixedly connected with a base; a first motor is fixedly connected to the left side of the top surface of the base, an output shaft of the first motor is fixedly connected with the input end of a speed reducer, the speed reducer is fixedly connected to the top surface of the base, a main shaft is fixedly connected to the output shaft of the speed reducer, and a driving wheel is fixedly connected to the main shaft in a sleeving mode. According to the invention, the washing liquid and the crude salt are fullymixed; the sleeve rotates in the feeding hole; the spray head is driven to rotate, washing liquid is sprayed out to be fully mixed with raw salt through rotation of the rotating spray head in the feeding port, the problems that the washing efficiency is low and time is wasted due to the fact that the washing liquid cannot be fully mixed with the raw salt when the washing liquid is sprayed to thesurface of the raw salt are solved, the washing efficiency is improved, and meanwhile time is saved.

Description

technical field [0001] The invention relates to the technical field of chemical machinery, in particular to a spiral salt washing machine for combined alkali production process. Background technique [0002] The soda ash industry is the earliest chemical industry established in my country. It has a solid foundation in basic research, industrial technology, and production scale. In the production process of combined alkali method, the raw salt needs to be washed, and the spiral salt washing machine is a special equipment for washing salt production, which can be used for washing raw salt and medium and coarse salt. The machine consists of three parts: transmission device, shell and spiral belt , when working, feed material at the tail end and add washing liquid, add spray washing liquid at the middle and upper part, the material is washed during transportation, the suspended solids overflow at the overflow weir at the tail, and the sediment is regularly discharged at the bottom...

AI Technical Summary

Problems solved by technology

[0003] In the process of washing raw salt with a spiral salt washing machine, it is necessary to add washing liquid to the raw salt, and the common method of adding is to spray the washing liquid on the surface of the raw salt, so that the washing liquid cannot be fully mixed with the raw salt, resulting in washing Low efficiency and waste of time. At the same time, after the raw salt is cleaned, the suspended solids and sediments of the raw salt are discharged, but there will still be a small amount of fine sand mixed in the raw salt, which cannot be cleaned, resulting in poor quality of the washed raw salt. It will affect the subsequent processing process. In addition, when the spiral blade rotates to make the raw salt rub against the cleaning box, the temperature of the cleaning box will increase, and the cleaning box will produce thermal deformation when working at a continuous high temperature, resulting in a reduction in the service life of the cleaning box and a waste of cost. problem, a spiral salt washing machine for combined alkali production process is now introduced
