Abstract

The invention discloses a filtering device used for calcium carbonate, comprising a reaction kettle, wherein a group of feeding holes is formed at the top of the reaction kettle, a discharge hole is formed in the bottom of the reaction kettle, a manhole is formed in the side wall of the reaction kettle; a filter plate is arranged in the middle of the reaction kettle, a clapboard is arranged at the bottom of the reaction kettle, a group of flow dividing devices are arranged on the clapboard, and the clapboard is located above the horizontal position of the discharge hole. The filtering device is reasonable in design and strong in continuous working capability, and can control the fineness of materials respectively through the filter plate, a metal cover, the clapboard and the flow dividing devices, so as to ensure the normal operation of subsequent processes.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a filter device for calcium carbonate. Background technique [0002] Calcium carbonate is usually reacted and synthesized in a reactor, and taken out after the temperature is lowered. However, under heating conditions, calcium carbonate is not very stable, it may react with other substances to generate impurities, and may also generate a certain amount of intermediates due to insufficient reaction, thereby affecting the purity of the product. In the traditional reaction, the raw materials for calcium carbonate synthesis need to be filtered and then reacted to ensure the fineness of the calcium carbonate produced. Contents of the invention [0003] Purpose of the invention: the purpose of the present invention is to provide a kind of filtering device for calcium carbonate for the deficiencies in the prior art. [0004] Technical solution: In order to achieve the ab...
