Granulator for soda lime and calcium lime and preparing method of granulator

Abstract

The invention relates to the preparation of chemical products, and particularly discloses a granulator for soda lime and calcium lime and a preparation method of the granulator. Compared with the prior art, the granulator and the preparation method has the advantages that the resource and the energy source are effectively saved, the rigidity of obtained grain is high, and the water content of a finished product can be better controlled. The technical scheme disclosed by the invention is that the granulator for the soda lime and the calcium lime comprises an electric motor, a drive shaft, a die and a raw material groove, wherein the drive shaft comprises a main drive shaft and an auxiliary drive shaft, and the die comprises a main die and an auxiliary die. The preparation method of the granulator comprises the following steps of preparation of raw materials, preparation of a semi-finished product and preparation of the finished product.

Description

technical field [0001] The invention relates to the preparation of chemical products, in particular to the preparation of soda lime and calcium lime and the equipment used in the preparation process. Background technique [0002] The existing process and equipment for preparing soda lime and calcium lime have many disadvantages. First, a large amount of waste of resources and energy: the existing extruders for preparing soda lime and calcium lime can only extrude semi-finished soda lime with a water content of more than 50%. When the water content is less than 50%, the extruder will be blocked, causing The machine is damaged, and if the moisture content is too high, it will take too long for the semi-finished product to enter the oven, and the oven needs to be adjusted to a higher temperature to make the moisture content of the final product meet the national standard, thus causing a double waste of energy and resources; Secondly, the hardness of the prepared soda lime and ...

Problems solved by technology

First, a large amount of waste of resources and energy: the existing extruders for preparing soda lime and calcium lime can only extrude semi-finished soda lime with a water content of more than 50%. When the water content is less than 50%, the extruder will be blocked, causing The machine is damaged, and if the moisture content is too high, it will take too long for the semi-finished product to enter the oven, and the oven needs to be adjusted to a higher temperature to make the moisture content of the final product meet the national standard, thus causing a double waste of energy and resources; Secondly, the hardness of the prepared soda lime and calcium lime particles is low: in the existing preparation process, due to the high water content of the semi-finished product entering the oven, large gaps are left after the water evaporates during drying, so that the obtained particles The hardness becomes lower, and the experimental data is 81%. Finally, the water content of the finished product is not well controlled: because the existing extruder needs the water content of the semi-finished product to exceed 50%, the resulting semi-finished product is too viscous, resulting in a It is easy to block, resulting in uneven raw materials in the oven, and cannot evenly dry semi-finished products, which eventually leads to uneven moisture content in the finished product
