Double liquid high pressure filling machine

Abstract

The invention relates to equipment for filling double-component materials into building cracks by high pressure, i.e. a double-fluid high-pressure filling machine. The hopper of a conventional filling machine is upon the suction inlet, so the conventional filling machine belongs to gravity-flow feeding. The defects are great power consumption and easy material gasification; the ordinary filling machine has only one set of pressure and flow parameters, however the requirements of on-site construction situations on pressure and flow are quite different. Two sets of crank slider mechanisms are driven by a driving gear shaft, two sets of grout cylinder units and suction and discharge valve banks are driven by the two sets of crank slider mechanisms, and thereby double-fluid filling is realized; by replacing the grout cylinder units, the suction and discharge valve banks and a hand drill on site, pressure, flow and proportion can be regulated; the effects of convenience, high efficiency and the like of on-site construction are particularly obvious.

Description

technical field [0001] The invention relates to a device for high-pressure pouring two-component chemical preparations into narrow spaces such as building cracks, in particular to a two-liquid high-pressure pouring machine. Background technique [0002] In the waterproof and plugging industry of buildings, single-component materials, such as polyurethane materials, are generally used at present, and injected into the gaps of buildings through ordinary filling machines. Due to the large viscosity coefficient and poor fluidity of such materials, it is difficult to reach very fine If the crack is deep, the plugging effect is poor. Due to the poor fluidity of the material, the ordinary filling machine adopts the method of vacuum suction. When the plunger starts the suction stroke, no material enters the plunger cavity, forming a certain degree of vacuum. When the plunger moves to the suction port, it is forced The material is sucked into the plunger chamber, then enters the fil...

AI Technical Summary

Problems solved by technology

The disadvantages of this method or structure are: high power consumption, because a vacuum space is formed when the material is sucked; and because of the vacuum space, the material is easily vaporized, which affects the performance of the material; and because an ordinary filling machine only has one set of pressure and flow parameters, but the construction conditions on site vary widely, some require large flow, and some require high pressure, it is impossible for the construction team to be equipped with all types of ordinary pouring machines and bring them to the site. The top of the feed port belongs to self-flow feeding, and the height of the hopper must be higher than the suction port
