Description

Technical Field

[0001] The utility model relates to the technical field of steel wastewater filtering, in particular to iron slag filtering equipment in steel production wastewater. Background Art

[0002] The steel industry refers to the industry that produces pig iron, steel, steel products, industrial pure iron and ferroalloys. It is one of the basic industries of all industrialized countries in the world. Economists usually use steel output or per capita steel output as an important indicator to measure the economic strength of various countries. The steel industry is also called the ferrous metallurgical industry. The steel industry is an important basic industrial sector and the material basis for the development of the national economy and national defense construction. A lot of wastewater will be generated in the steel production, and this wastewater contains a certain amount of iron slag.

[0003] At this time, it is necessary to use filtering equipment to filter the iron slag in the wastewater. The filter in the filtering equipment needs to be cleaned after using it for a period of time. However, the existing technology fixes the filter inside the filter tank with bolts. Too many bolts will bring a certain amount of work to the disassembly of the filter, resulting in inconvenient disassembly of the filter, affecting the cleaning efficiency of the filter. Utility Model Content

[0004] The utility model aims to provide an iron slag filtering device in waste water from steel production to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an iron slag filtering device in steel production wastewater, comprising a filter tank, a frame is slidably connected to the inside of the filter tank, a plurality of symmetrically arranged cross plates are fixedly connected to the inner wall of the filter tank, a plurality of cross plates are fixedly connected to the top ends of the plurality of cross plates, a plurality of fixed frames are slidably connected to pressure rods, a plurality of pressure rods are fixedly connected to the ends away from each other with pressure blocks, a plurality of pressure blocks are fixedly connected to springs at positions corresponding to the fixed frames, a plurality of fixed frames are slidably connected to the insides of the plurality of fixed frames, a plurality of filter screens are commonly fixedly connected to the top ends of the plurality of plug rods, a plurality of fixing grooves are provided at positions corresponding to the pressure rods, symmetrically arranged mounting blocks are fixedly connected to the two side walls of the filter tank, a plurality of mounting blocks are commonly fixedly installed with hydraulic cylinders, and a conjoined plate is fixedly connected to the top ends of the output ends of the two hydraulic cylinders.

[0006] Preferably, the springs are all fixedly connected to the outer wall of the fixing frame, and the springs are all in a contracted state.

[0007] Preferably, the pressure-bearing rods are slidably inserted into the fixing grooves at positions corresponding to the internal positions of the fixing frame.

[0008] Preferably, a water outlet is provided on the front wall of the filter pool, and protection boxes are fixedly connected to both side walls of the filter pool, and the hydraulic cylinders are located inside the protection boxes.

[0009] Preferably, the connected plates are respectively fixedly connected to two side walls of the frame.

[0010] Compared with the prior art, the beneficial effects of the utility model are: a hydraulic cylinder, an insertion rod, a frame, a pressure rod and a fixed groove, etc. are set. When the filter needs to be disassembled, it is only necessary to move the frame downward through two hydraulic cylinders. The frame will be retracted to the inside of the outer wall of the filter tank when it moves downward. At the same time, the frame will no longer abut the pressure rod. At this time, each spring will cause the pressure rod to fall out of the fixed groove respectively. At this time, the insertion rod loses its fixation, and the filter can be lifted up for disassembly. Not only is the fixing effect of the filter excellent, but the disassembly and installation of the filter are also very convenient, and it is worthy of popularization and use.
