Polyethylene fiber concrete production device and preparation method thereof

Abstract

The invention discloses a polyethylene fiber concrete production device and a preparation method thereof, belongs to the technical field of squeeze casting, and aims to solve the problems of long stirring time, non-uniform mixing, inconvenience in addition of water in the stirring process, easiness in agglomeration and condensation of part of cement, low production cost and the like due to the fact that various raw materials are poured into a stirring tank together for stirring in the prior art. The proportion of part of raw materials is inconvenient to control; a second bevel gear is driven to revolve around a second rotating shaft when the second rotating shaft rotates, the second bevel gear is in meshed connection with a first bevel gear, and the first bevel gear is fixedly mounted on the inner wall of the tank body through a first fixing rod, so that the second bevel gear rotates while revolving; according to the material mixing device, the material mixing plate reciprocates up and down to extrude the materials and realize material turning, and the stirring effect is improved in cooperation with stirring of the first stirring shaft and the second stirring shaft.

Description

technical field [0001] The invention relates to the technical field of extrusion casting, in particular to a polyethylene fiber concrete production device and a preparation method thereof. Background technique [0002] Polyethylene fiber (ethylene fiber) refers to the fiber material obtained by spinning polyethylene by melt spinning, including short fibers and filaments. The mechanical strength of this fiber can be adjusted through the spinning process parameters, and the wet state The strength and elongation are the same as the dry state. Polyethylene fiber has the advantages of high strength, low density and good insulation, but its low thermal load capacity and cold creep limit its application. It is mainly used to produce various industrial textiles, especially It is a product such as filter material, tarpaulin and mesh belt. Studies have shown that by adding polyethylene fibers to concrete, the concrete is mixed with short fibers distributed in random directions, which ...

AI Technical Summary

Problems solved by technology

[0003] In the production of polyethylene fiber concrete, various raw materials are often poured into the mixing tank for mixing. The mixing time is long and the mixing is not uniform enough, which is easy to affect the quality of the concrete, and it is not convenient to add in the mixing process after the mixing is uniform. water, it is easy to make part of the cement coagulate, and it is not easy to control the proportion of some raw materials when adding raw materials
