一种压滤机大梁板偏载检测报警装置A filter press girder plate eccentric load detection and alarm device

技术领域technical field

本实用新型涉及板框式压滤机领域,具体涉及一种压滤机大梁板偏载检测报警装置。The utility model relates to the field of plate-and-frame filter presses, in particular to an eccentric load detection and alarm device for a girder plate of a filter press.

背景技术Background technique

板框式压滤机是由很多块滤板和滤框叠合组成过滤室,用压力做为过滤推动力的机器,企业常用液压压紧的方式进行压滤,液压压紧是利用液压站经机架上的油缸部件推动压紧板压紧板框。压紧过程中,止推板承受油缸的推力,大梁板连接在止推板和油缸座之间,从而承受一定的拉伸力。当出现滤板底部夹料或者油缸轴心偏移等问题时,大梁板受力不均衡也就是出现偏载,这样会造成滤板合膜不严密,造成跑料、爆水,大梁板断裂的安全事故,是安全生产中需要严格规避的风险。The plate and frame filter press is a filter chamber composed of many filter plates and filter frames, which uses pressure as the driving force for filtration. The oil cylinder part on the frame pushes the pressing plate to press the plate frame. During the pressing process, the thrust plate bears the thrust of the oil cylinder, and the girder plate is connected between the thrust plate and the oil cylinder seat, so as to bear a certain tensile force. When there are problems such as material clamping at the bottom of the filter plate or offset of the cylinder axis, the force of the girder plate is unbalanced, that is, eccentric load occurs, which will cause the filter plate to not tightly seal the film, resulting in material running, water explosion, and girder plate fracture. Safety accidents are risks that need to be strictly avoided in safety production.
