Embodiment Construction

[0008] Combine box below figure 1 The implementation steps of the present invention are further illustrated: according to the wet diatomite removal process step of the present invention, the wet diatomite mined from the diatomite mine is first knocked into small fragments of 5-10cm; The broken diatomite is beaten with water; the third step is to use a pump to pump it through the screen for wet sand removal, and the fourth step is to beat the impurity-removed diatomite slurry to the mixing tank for use, and then enter the next step Manufacture of microporous calcium silicate insulation products. The present invention only protects the wet diatomite impurity removal process steps, not the well-known microporous calcium silicate thermal insulation product process steps.

Abstract

The exploited wet diatomite is crushed, beated into 15-20% concentration diatomite pulp by adding water and wet sieved to eliminate sand before pumped into pulping pool to produce porous heat-insulating calcium silicate product. Compared with the available dry process, the wet process of the present invention has greatly reduced production cost, and what is more important, the product has low impurity content, high quality, increased activity, low density and raised bending strength.

Description

(1) Technical field [0001] The invention relates to a process for removing impurities of wet diatomite. (2) Background technology [0002] Usually, the first step in the process of manufacturing microporous calcium silicate thermal insulation products is to make diatomite slurry. The wet diatomite mined from diatomite mines needs to be dried into dry diatomite and then crushed by a pulverizer. After a certain fineness, add appropriate amount of water to make diatomite slurry. This kind of diatomite pulp needs to be dried and crushed from dry diatomite to two steps. The disadvantages are: drying requires manpower, which is often affected by weather and natural conditions, and clay and stone powder are mixed in during the drying process. Such impurities will affect the quality of the product; dry diatomite needs to be ground into powder, causing dust pollution and affecting the health of employees, and it is difficult to remove impurities that will affect the quality of micro...
