Existing chemical engineering filtration devices still have the following problems in terms of filtration efficiency, impurity removal effect, and intelligent control: (1) In existing chemical engineering filtration devices, when treating chemical engineering wastewater, impurities will gradually accumulate on the surface of the filtration medium, and the filter material is prone to serious clogging problems, resulting in low filtration efficiency; (2) The impurities filtered out by existing chemical engineering filtration devices may be mixed with uncompletely dissolved chemical raw materials, leading to waste of raw materials. Most chemical raw materials are toxic and harmful substances, which will cause environmental pollution; (3) The filter residues generated during the filtration process of existing chemical engineering filtration devices usually contain various chemical substances.

A liquid filtration structure is fixedly installed inside the filtration tank 1, and the liquid filtration structure is used to filter harmful impurities generated in chemical materials. A discharge pipe 3 is fixedly installed at the bottom of the filtration tank 1. The discharge pipe 3 penetrates the filtration tank 1 and the two end ports are respectively located inside and outside the filtration tank 1. Three support legs 5 are fixedly installed at the bottom of the filtration tank 1. An exhaust pipe 6 is fixedly installed at the top of the filtration tank 1. The exhaust pipe 6 penetrates the filtration tank 1 and the two end ports are respectively located inside and outside the filtration tank 1.

Both ends of the connecting rod 10 are respectively connected to the output end of the micro motor 9 and the fan 11. The connecting rod 10 is rotatably connected to the fixed rod 8. The gas filtration layer 7 is fixedly connected to the inner side wall of the exhaust pipe 6. The gas filtration layer 7 is located on the side of the fixed rod 8 away from the filtration tank 1. When the gas filtration structure operates, the fan 11 rotates to generate negative pressure, attracting the harmful gases in the chemical materials and discharging them outward through the exhaust pipe 6. At the same time, the gas filtration layer 7 will filter the harmful gases, making the discharged gas environment-friendly.

An electromagnetic valve 39 is fixedly installed at the bottom of the water storage plate 43 in the inclined direction, and the position of the electromagnetic valve 39 is close to the top of the second filter layer 13 in the inclined direction. When the chemical materials flow through the electromagnetic valve 39 to the second filter layer 13, the chemical materials can flow to the bottom of the second filter layer 13 in the inclined direction according to the gravity, so that the contact area between the chemical materials and the second filter layer 13 is larger during the filtration process, and a better filtration effect can be obtained.

The chemical materials flow out from the flat nozzle water collector 41 and strike the impact blades 23, thereby driving the gas filtration structure and the stirring structure to operate by means of the first transmission mechanism and the second transmission mechanism. At the same time, the chemical materials can reduce their own impact force after striking the blades, enhancing the fluidity and mixing effect of the chemical materials. Then, the chemical materials pass through the first filter layer 12 arranged obliquely, which can filter the chemical materials for the first time and collect the unreacted solid impurities therein through the first impurity discharge pipe 37. The chemical materials continue to enter the water storage plate 43. If the current chemical materials require special reaction conditions, the reaction conditions in the filtration tank 1 can be changed by the electric heater 34. At the same time, the feeding port 42 can also add reagents that react with the chemical materials. After the chemical materials react, the electromagnetic valve 39 is controlled to open, enabling the chemical materials to continue flowing to the second filter layer 13. The second filter layer 13 filters the chemical materials for the second time and collects the solid impurities therein through the second impurity discharge pipe 38. Finally, the drain valve 4 is opened to collect the filtered chemical materials.

Those skilled in the art can make modifications to this embodiment without creative contributions according to needs after reading this specification, but as long as it is within the scope of the claims of the present invention, it is protected by the patent law.
