A kind of manufacturing method of the rotary cutting device of high viscosity polymer gel

Abstract

The invention discloses a manufacturing method of a high-viscosity polymer gel rotary cutting device. (1) Make the connecting rod, 2-4 concave blades and the electric driver; the upper end of the connecting rod is a hexagonal column with an outer diameter of 8-10mm and a length of 350-450mm; the specifications of the concave blades are the same, and the expanded length is 120-150mm. The width is 20mm, the thickness is 1.5mm, and the concave blades are bent upward or downward from the center 1 / 2-3 / 5, and the bending angle is 30-60°; (2) 2-4 concave blades Cross-welding to form a superimposed concave blade; when multiple concave blades are superimposed, there are three bending directions at both ends: simultaneous upward bending, simultaneous downward bending or some upward bending and some downward bending; connecting rods The lower end is threaded in the center of the concave blade. (3) Fix the electric driver on the upper end of the connecting rod, and the electric driver itself is used as the driving device. The device of the invention has a simple structure, the concave design of the blades improves the axial shearing effect of the device, and the overlapping design of the concave blades further strengthens the shearing effect.

Description

technical field [0001] The invention belongs to the technical field of building material engineering, in particular to a manufacturing method of a high-viscosity polymer gel rotary cutting device. Background technique [0002] With the acceleration of my country's industrialization process, the demand for concrete and other building materials is increasing day by day. The annual demand and production volume both exceed 2 billion cubic meters, and are still growing at a certain speed. As a new type of concrete admixture, internal curing agent has gradually become an important admixture in the concrete industry because of its good inhibitory effect on high-strength and high-performance concrete cracking and hydration promotion. There are two types of existing internal curing agents, gel and powder, both of which have their own advantages and disadvantages in terms of construction convenience and price. On the one hand, concrete is a Bingham fluid, and its fluidization charact...

AI Technical Summary

Problems solved by technology

At present, most of the rotary cutting (shearing) devices used for high-viscosity fluid materials only have a stirring function, and the shearing function is extremely weak. They cannot efficiently cut polymer gels with flexible networks and reduce the degree of cross-linking of the network; However, although some devices with shearing function can shear gel, they cannot effectively stir the crushed gel solution, and cannot fully and uniformly disperse the crushed gel. In addition, some shearing and stirring devices need to be equipped with high-power power devices ,higher cost

In general, the current traditional rotary cutting device has a single type and incomplete functions, and cannot better meet the needs of disintegrating high-viscosity polymer gels.
