混凝土卸料开关设计得是否合理,将影响到混凝土的浇筑速度和工人的劳动强度。通常混凝土立罐和卧罐的弧形卸料门,不管是单开门还是双开门,弧门的回转中心和罐体卸料口曲面中心互相重合,如图1、图2。这样的弧门在开关过程中始终和罐体卸料口互相紧密接触,正因为如此,制作安装上的误差、罐口和密封橡胶板的磨损、以及混凝土的粘结都将严重地影响弧门的正常工作。例如弧门与卸料口之间的间隙如果过大, The reasonable design of the concrete unloading switch will affect the pouring speed of concrete and the labor intensity of workers. Usually, the curved discharge doors of concrete vertical tanks and horizontal tanks, whether they are single-open doors or double-open doors, overlap the curved center of the arc gate and the center of the tank discharge port, as shown in FIGS. 1 and 2 . Such an arc gate is always in close contact with the tank discharge port during the switching process. Because of this, errors in the production and installation, abrasion of the tank port and the sealing rubber sheet, and adhesion of the concrete will all seriously affect the arc gate. The normal work. For example, if the gap between the arc gate and the discharge port is too large,
