Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Firstly, in order to facilitate understanding of the horizontal filter for chemical industry provided by the embodiment of the application, an application scenario of the horizontal filter for chemical industry is explained first, the horizontal filter for chemical industry in the embodiment of the application is subjected to multistage filtration, impurities in chemical liquid are precipitated and adsorbed, and meanwhile, high-pressure back flushing is equipped to remove the filtered impurities, so that blockage is avoided.

The following describes the horizontal filter for chemical industry provided in the embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a horizontal chemical filter according to an embodiment of the present invention; horizontal filter for chemical industry in the embodiment of this application includes: a settling tank 1; this gunbarrel 1 is as the supporting body in this application embodiment for pour into the great impurity of sedimentation in gunbarrel 1 with chemical industry liquid, the bottom of this gunbarrel 1 is provided with supporting leg 2 that is used for supporting gunbarrel 1. And be provided with the sediment bottom plate 4 of U-shaped in 1 bottom of gunbarrel, the big impurity that the U-shaped sediment board will deposit and fall is convenient for clear away to be provided with the blow off pipe 5 with sediment bottom plate 4 intercommunication in the bottom of gunbarrel 1, and be equipped with valve 6 on blow off pipe 5.
