Description

Splash-proof device for drainage pipeline of plate-and-frame filter press Technical Field The utility model belongs to the technical field of filter press pipeline systems, and particularly relates to a splash preventing device for a drainage pipeline of a plate-and-frame filter press. Background In the installation process of plate-type filter press blowback systems in various fields of iron and steel, metallurgy, chemical industry, sewage treatment and the like, the connection between a pressure air pipeline of the blowback system and a feeding pipeline and a return water pipeline is not considered. In the operation process of the plate-and-frame filter press, the compressed air pressure of the back-flushing system is high, the water collecting pipeline is not smooth in drainage, and mud in the pipeline is splashed to pollute the operation environment. In the design process of the back-blowing system of the plate-and-frame filter press, the field effect verification is lacking, so that staff can frequently clean the system, the working intensity of the staff is increased, potential safety hazards exist in the aspects of equipment intrinsic safety hazard source identification and risk evaluation, and personal injury accident risks exist in the processes of staff spot inspection and inspection/maintenance operation. In the prior art, after the plate-and-frame filter press stops running, a protective cover is added on one side of a water collecting tank to prevent mud splashing of a pipeline, and the effect verification proves that the mud splashing prevention effect is not ideal. Therefore, a splash-proof device for a drainage pipeline of a plate-and-frame filter press is provided. Disclosure of utility model The utility model aims to provide a splash-proof device for a drainage pipeline of a plate-and-frame filter press, which has the splash-proof function of the drainage pipeline of the plate-and-frame filter press, and solves the problems that in the prior art, the connection between a pressure air pipeline of a back-blowing system and a feed pipeline and a return water pipeline is not considered, and in the operation process of the plate-and-frame filter press, the pressure of compressed air of the back-blowing system is high, the drainage of a water collecting pipeline is not smooth, so that slurry in the pipeline is splashed, and the operation environment is polluted. In order to achieve the above purpose, the utility model provides a splash-proof device for a drainage pipeline of a plate-and-frame filter press, which comprises the plate-and-frame filter press, wherein the front side of the plate-and-frame filter press is connected with a mud inlet pipe, the mud inlet pipe is connected with a back-blowing mud pipe, the rear side of the plate-and-frame filter press is connected with a pressure air back-blowing pipe, the pressure air back-blowing pipe is provided with a pressure air back-blowing valve, two sides of the bottom of the plate-and-frame filter press are provided with water outlets, two sides of the bottom of the plate-and-frame filter press are provided with a first water collecting tank and a second water collecting tank, one side of the first water collecting tank is connected with a drain pipe through a first connecting pipeline, one side of the second water collecting tank is connected with the drain pipe through a second connecting pipeline, the front side of the plate-and-frame filter press is led out of the first water return pipe and the second water return pipe, and the second water return pipe is connected with an angle blowing air inlet pipe.
