The invention discloses a filtering device for chemical waste treatment, and belongs to the technical field of chemical machinery. The filtering device for the chemical water treatment comprises a bracket, a filtering tank, a filtering screen and an anti-blockage mechanism, wherein the anti-blockage mechanism comprises an aerostatic press and an air delivery pipe; the air delivery pipe comprises an air inlet part and a working pipe; the aerostatic press is communicated with the air inlet part; the working pipe is helically distributed and horizontally arranged; the working pipe is located below the filtering screen and approaches the filtering screen; the working pipe comprises an inner end and an outer end; the inner end is communicated with the air delivery pipe; the working pipe is provided with multiple air outlets which are open upwards obliquely. Air is delivered into the working pipe by using the aerostatic press and is exhausted via the air outlets; as the multiple air outletsare obliquely arranged and the working pipe is helical, chemical water above the working pipe is enabled to do helical ascending motion; the fact that a substance which is larger in particle remainingon the filtering screen cause blockage is prevented; the filtering efficiency can be greatly improved and the filtering effect is improved.

The invention discloses a pipeline connection mechanism used for chemical waste water transportation and capable of preventing leakage. The pipeline connection mechanism used for chemical waste watertransportation and capable of preventing leakage comprises a connection shell, a connection head, a first flange plate and a second flange plate. Connection heads are installed on the left side, the right side, the upper side and the lower side of the connection shell, blocking plates are connected into the connection heads in a threaded mode, partition plates are arranged in the connection shell,the outer sides of the blocking plates are connected with external connection pipes in a threaded mode, moving rings are connected to the outer sides of the external connection pipes in a threaded mode, and outer covers are fixed to the outer sides of the moving rings. According to the pipeline connection mechanism used for chemical waste water transportation and capable of preventing leakage, the moving rings are arranged, and the moving rings are connected with the external connection pipes in a threaded mode, so that through rotation of the moving rings, the outer covers can squeeze a first inflatable airbag body, and air inside the first inflatable airbag body enters a second inflatable airbag body through a communication pipe so as to seal pipelines with different diameters and avoidthe later leakage.
