Sizing agent discharging device

Abstract

The invention relates to a slurry feeder, which comprises a barrel body with a material inlet and a material outlet, a gate for adjusting the opening of the material outlet, a rotating shaft of the gate, a turntable and a turntable tightening screw. The discharge port is set on the barrel body through the pitch rotation of the ram shaft, and the turntable is fixed with the ram through the ram shaft. There is an arc-shaped slot on the turntable. physically. A kind of slurry feeder of the present invention, according to the grouting materials of different properties, adjusts the opening of the discharge port by rotating the turntable to drive the shutter, and then fixes the turntable by tightening the screws of the turntable. The angle of the plate is fixed, so as to fix the opening of the discharge port, adjust the flow rate of the grouting material, ensure the flow rate is controllable, and prevent the test from failing due to too fast or too slow feeding. At the same time, the structure of the grout discharger is simple, low cost.

Description

Technical field [0001] The invention relates to a slurry pouring device, in particular to a slurry feeder. Background technique [0002] In the pourability test of concrete crack grouting material, in order to compare the pourability of different grouting materials, it is necessary to pour the grouting material into the simulated cracks, and then compare the fullness of different performance grouting materials in the simulated cracks. , Filling time and other grouting indicators, so as to evaluate the grouting ability. However, if the feeding equipment and operation methods used are not uniform, such as the use of different sizes of funnels or different sizes of shovel for filling and feeding, or the difference in the height of the hopper or the shovel opening due to human factors All directly affect the accuracy of the test results. At the same time, due to the difference in consistency and viscosity of the various grouting materials in the comparison test, different specificat...

Problems solved by technology

However, if the feeding equipment and operation methods used are not uniform, such as using funnels of different sizes or shovels of different sizes for perfusion feeding, or the distance between the mouth of the funnel or the shovel and the simulated crack opening is different due to human factors Both directly affect the accuracy of the test results. At the same time, due to the differences in the consistency and viscosity of the various grouting materials in the comparative test, feeding devices of different specifications are required, which increases the cost and brings inconvenience to the operation.

In addition, it is not easy to grasp how much grouting material needs to be added in the grout feeder. Adding too much will cause waste, adding too little will not fill the simulated cracks, and refilling will cause test errors or even lead to test failure.
