Description

Calcium silicate board powder raw material stirring device

Technical Field

The utility model relates to calcium silicate board production technical field, concretely relates to calcium silicate board powder raw material mixing device.

Background

The calcium silicate board is a board made up by using loose short fibre of inorganic mineral fibre or cellulose fibre as reinforcing material and using siliceous-calcareous material as main body cementing material through the processes of pulping, forming and curing reaction in high-temp. high-pressure saturated steam to form calcium silicate gel body.

The production method of the calcium silicate board comprises a static steam-pressing method, a dynamic hydrothermal synthesis method and a secondary reaction method, and currently, the calcium silicate board is mostly produced by adopting a static process in China, namely, raw materials and auxiliary materials are mixed according to a certain proportion, a proper amount of water is added, the mixture is heated to a certain temperature under the stirring condition to carry out gelation, and then the calcium silicate board heat-insulating material product is obtained through molding, steam-pressing maintenance and drying.

When the calcium silicate board is produced, siliceous raw materials, calcareous raw materials and reinforcing fibers are used for preparing slurry, and the slurry is fully stirred and mixed, so that different types of raw materials can be uniformly distributed in the slurry.

The production process of the calcium silicate board production line by using the slurry mainly comprises two processes: the slurry stirring device for calcium silicate board production provided by the Chinese patent CN213254058U can circularly pump the slurry from the bottom of the stirring tank through a pumping pump so as to convey the slurry to the upper part, so that the slurry is uniformly stirred, but for the slurry containing solid particles or with high viscosity, the pumping pump can only re-input the slurry into the stirring tank from one side of the stirring tank, the input slurry can be possibly accumulated on one side of the bottom of the stirring tank, the solid particles can quickly wear a pumping pump body, and the slurry with high viscosity is easy to block the pumping pump.

Meanwhile, in the prior art, an anchor type or frame type stirrer is often used for slurry with high viscosity, for example, a slurry flowing device for preparing a calcium silicate plate, which is provided by Chinese patent CN214026393U, can obtain large shearing force along the wall surface of an inner cylinder when the slurry flows at low speed, so that material settlement and wall surface attachment can be prevented; however, the slurry with high viscosity has high settling speed and is easy to adhere to walls, and under the influence of viscous force, the liquid can only be in a laminar flow state, and particularly, the laminar flow can only be in the vicinity of the blades, and the slurry in the positions far away from the blades is still static, so that the circulating flow of the liquid in the whole container is difficult to form, and stirring dead angles are generated in the container; the improvement type eccentric agitator that china patent CN204193839U provided uses the stirring mode of eccentric formula and high low-speed combination, stirs no dead angle, and stirring effect is good, and can restrict the swing of the (mixing) shaft that causes by the fluid for mix stirring speed, nevertheless can't transport thick liquids from the bottom to the top in its stirring process and realize the stirring of upper and lower reciprocating circulation.
