An air-bleeding type stirring and exhausting device

Abstract

The invention relates to an air-entraining type stirring exhaust device which comprises a base structure comprising a base, a support column and an upper top plate. The upper top plate is fixed to thebase through the support column, and the center position of the upper top plate is provided with a small hole; the base is fixedly provided with a slurrying barrel, and a slurry outlet is formed in the position, close to the bottom, of the slurrying barrel and provided with a slurry discharging valve; the stirring exhaust device further comprises a telescopic rod installed at the bottom surface of the upper top plate, and the telescopic rod communicates with a motor on the surface of the upper top plate through a wire penetrating through the small hole; the bottom of the telescopic rod is provided with a fixed head arranged over the slurrying barrel; the stirring exhaust device further comprises a stirring sleeve head for stirring concrete, an exhaust sleeve head for exhausting for the concrete and a pressing sleeve head for transferring the concrete; and the stirring sleeve head, the exhaust sleeve head and the pressing sleeve head are connected to the fixed head at the bottom end ofthe telescopic rod according to different requirements separately. According to the stirring exhaust device, the problems that the bubble removal efficiency of tools, such as a vibrating table and avibrator used in a laboratory, is low and air is mixed in the later material transfer process are solved.

Description

technical field [0001] The invention relates to an air-entraining type stirring exhaust device, which belongs to the field of cement concrete preparation for experiments. Background technique [0002] When using cement concrete materials in indoor tests, it is often chosen to slightly stir the concrete materials by tapping the outer surface of the mold or using a stirrer. Although this method is simple, it can only remove air bubbles inefficiently. [0003] In order to overcome this shortcoming, vibrating tables or vibrating rods are often selected in the laboratory to help the air bubbles in the concrete material to be removed. The resistance received is relatively large, which has a great impact on its removal efficiency, resulting in a long time for vibration and failure to achieve good results. At the same time, the concrete after vibrating in the test needs to be transferred into the mold for the second time. During this process, there will be gas re-entering, which wi...
