Description

Pipeline filter equipment before sour line waste acid pump that rolls Technical Field The utility model belongs to the technical field of steel pickling, and particularly relates to a front pipeline filtering device of a pickling line waste acid pump. Background The cold-rolled strip steel is required to be pickled during production, acid substances are adopted to remove rust on the surface of steel, the pickling solution after use contains a large amount of metal impurities, the discharged waste acid is required to be recycled for protecting the environment and reducing the cost, and the waste acid is pumped to an acid regeneration device for regeneration through a waste acid pump, but in the use process, the waste acid pump and a pipeline are likely to be blocked frequently due to large impurities in the waste acid such as a squeezing roller rubber, so that the waste acid discharge is abnormal, the waste acid pump is frequently disassembled by personnel, and the pump spare parts are abnormally damaged. Disclosure of utility model The utility model aims to provide a pipeline filtering device before an acid rolling line waste acid pump, which can filter waste acid before the waste acid pump. In order to achieve the aim, the technical scheme adopted by the utility model is that the front pipeline filtering device of the acid rolling line waste acid pump comprises a cylinder body and a filtering plate, The side wall of the cylinder body is horizontally communicated with a liquid inlet pipe and a liquid outlet pipe, the liquid outlet pipe is communicated with a liquid inlet of the waste acid pump through a pipeline, the filter plate is vertically arranged inside the cylinder body, and a plurality of filter holes are formed in the filter plate. Preferably, two sliding grooves are vertically formed in the barrel, and two ends of the filter plate are inserted into the sliding grooves. Preferably, the two sides of the filter plate are vertically fixed with reinforcing plates, the reinforcing plates are in contact with the inside of the cylinder body, and the reinforcing plates are arranged above the liquid inlet pipe and the liquid outlet pipe. Preferably, the bottom of the side wall of the filter plate is communicated with a drain pipe, the drain pipe is arranged between the liquid inlet pipe and the filter plate, and a valve is arranged on the drain pipe. Preferably, the top of the cylinder body is connected with a cylinder cover through a flange. Preferably, the top of the side wall of the filter plate is communicated with a cleaning pipe, and the cleaning pipe is arranged between the liquid outlet pipe and the filter plate. Compared with the prior art, the front pipeline filtering device of the acid rolling line waste acid pump has the following advantages: (1) The waste acid before the waste acid pump can be filtered through the cylinder and the filter plate, so that large impurities in the waste acid are prevented from entering the waste acid pump to damage equipment, and the cylinder is small in size and does not occupy space; (2) The filter plate is arranged in the chute, is convenient to detach and clean, (3) The design is simple and the use is easy.
