Description
Technical Field
The utility model belongs to the technical field of high-speed filter, concretely relates to high-speed filter leak protection material and sieve welding seam open welding device.
Background
The pot-type high-speed filter is the earliest and most common one in the sewage advanced treatment in the environmental protection field, is particularly suitable for purifying and treating steel rolling in steel enterprises, turbid water in continuous casting and side-filtration treatment in a circulating water system, can ensure the high quality of the effluent water quality under the condition of more raw water suspended matters, and has the advantages of high filtering speed, large treated water amount, small occupied area and the like.
In whole turbid circulating water system, the water after the jar-type high-speed filter mainly uses the system carries out filtration treatment, gets rid of the suspended solid such as impurity in aquatic mainly is iron scale, grease and minute quantity other impurity, improves the quality of water of system, satisfies user's operation requirement.
In the structural design of the tank type high-speed filter, a filter cap sieve plate boundary is divided into an upper filter bin and a lower filtered water collecting bin, the tank type filter is a tank body with the height of 8230 mm and the diameter of 5000 mm, the upper filter bin is a multilayer filler, anthracite, a pebble cushion layer, quartz sand and the like are about 2600 mm thick filter layers, a diameter of 400 mm water inlet pipe is arranged in the middle, raw water flows out from a water inlet at the bottom of the filter tank to the top of the filter material layer of the filter through a central water inlet pipe with the diameter of 400 mm, is filtered through the filter material layer and flows into the filtered water collecting bin at the lower part through the sieve plate filter cap; the lower water collecting bin collects the filtered water discharged from the sieve plate filtering cap and the filtered water enters the cooling tower through the water outlet pipe.
Since the turbid circulating water system of a continuous casting machine of an Angang second smelting and rolling mill runs, the blockage condition of a cooling nozzle of the continuous casting machine is more and more serious along with the further expansion of the production energy, so that great restriction is caused to the production, and main blockage substances are anthracite and quartz sand; a large amount of anthracite and quartz sand are also found in a cooling tower and a turbid circulating water clean water tank, in the whole turbid circulating water system, impurities entering water under normal conditions mainly comprise iron oxide scales, grease and a very small amount of other impurities, and the anthracite, the quartz sand and the like appear in the turbid circulating water at present, which belongs to an abnormal phenomenon mainly caused by material leakage of a high-speed filter.
Through to high-speed filter upper portion manhole to filter material inspection discovery in the filter, the high reduction of filter material is more in the filter, and some inside filter materials of filter appear local pit after normal filtration, clear away the filter material is whole, and the discovery filter plate warp seriously, and the filter cap has the breakage phenomenon, piles up a large amount of anthracites, quartz sand in the sump pit, and the reason that causes high-speed filter material leakage has following several: 1. the sieve plate of the filter with the diameter phi of 5000 mm and the thickness of 25 mm is sunken and deformed; 2. although a seamless pipe with the diameter phi of 108 mm is supported below the sieve plate, the strength is insufficient due to corrosion and a 'pot bottom' slope of a foundation at the bottom of the water collecting bin, and a filter cap is damaged due to deviation and deformation of a filter material; 3. welding seams between the phi 400 mm central water feeding pipe and the sieve plate are welded, and the filter material enters the water collecting bin from the filter material bin; 4. the rib plate at the welding seam of the water feeding pipe tears the pipe wall to cause the filter material to enter the water collecting bin.
The final reason for the four above cases: the sieve plate of the filter cap in the middle of the filter has overlarge area and insufficient strength (the diameter is 5000 mm and the thickness is 25 mm), the weight of the filler of the filter material bin and raw water is about 80 tons, when the filter works, the sieve plate of the filter cap forms a circular pit, and the filter material deviates on the sieve plate to extrude the filter cap to be damaged; meanwhile, the gravity of the filter material and the raw water and the up-and-down reciprocating impact force on the sieve plate during back washing cause the welding seam and the rib plate of the central water feeding pipe and the sieve plate to be torn, and the filter material enters the lower water collecting bin from the filter material bin, so that the material leakage phenomenon is caused. Therefore, the root cause of the leakage is solved, and the deformation of the sieve plate of the filter cap is prevented.
