Description
Technical Field
The utility model relates to a sewage treatment device technical field, in particular to plate and frame filter press drainage welt.
Background
The special high-pressure plate-and-frame filter press is core equipment for deep dehydration of production sludge, has the characteristics of systematization of production operation, high feeding and squeezing pressure, high production efficiency, good deep dehydration effect and the like, and is also core equipment for deep dehydration and drying projects of the sludge. The method is characterized in that conditioned and tempered sludge is conveyed to a filter cavity of a filter press at a high pressure by a plunger pump, and after a set feeding time is reached, a specially-made variable-cavity filter plate is deeply extruded by a high-pressure oil cylinder, so that the sludge is further dehydrated under a high-pressure condition. In order to maintain the best performance of the equipment, the production operation parameters need to be noticed in the daily production process, and the working condition of the equipment is ensured to be perfect. 1. The filter cloth is kept clean and is not damaged, and the filter cloth of the filter press needs to be washed every day; 2. ensuring the smoothness of the diversion liner, the diversion trench and the diversion hole; 3. the condition of the filter plates is inspected during production every shift, and a certain number of filter plates with broken springs need to be replaced and maintained. Maintenance is required in time for the deformed filter plate. 4. Ensure that the production feeding squeezes enough, the feed time is enough to realize that mud cake production quality is stable up to standard, practice thrift the medicament, and can make high pressure plate and frame filter press keep at better operating condition, extension filter plate life. Each high-pressure plate-and-frame filter press has 50 filter plates, and each filter plate has 2 concave-convex rubber plates. After a period of time, the concave-convex rubber plate is worn and deformed, and the water permeability is reduced, so that the sludge dewatering effect is poor.
The original concave-convex rubber plate size is as follows: diameter of 1200mm projection diameter: number of 6mm projections: 9000 pieces/m 2 The contact area between the convex part of the rubber plate per square meter and the filter cloth is 0.2543m 2 The price of the single chip is higher, and special production is needed.
SUMMERY OF THE UTILITY MODEL
The utility model provides a high-pressure plate frame filter press manganese steel drainage welt to solve the frequent wearing and tearing of unsmooth rubber slab and change among the prior art, the problem that drainage dehydration is inefficiency. In order to achieve the above purpose, the utility model adopts the following technical scheme:
the manganese steel water filtering lining plate of the high-pressure plate-and-frame filter press with high water permeability comprises a filter plate, wherein steel filter screens are arranged on two side surfaces of the filter plate.
Furthermore, the steel filter screen is composed of manganese steel bars which are staggered transversely and vertically.
Furthermore, the diameter of the manganese steel bar is 2mm-5mm.
Further, the diameter of the manganese steel bar is 3mm.
Furthermore, the steel filter screen is woven by 16 transverse manganese steel bars and 16 vertical manganese steel bars per square decimeter to form a water filtering lining plate, and the contact area of the manganese steel net and the filter cloth per square decimeter is 0.048m 2
Further, flange portions are arranged on two sides of the filter plate along the circumference of the filter plate, and the steel filter screen is arranged on the inner side wall of each flange portion.
Further, adopt welding mode to be connected between steel filter screen and the flange portion inside wall, it can to cut the welding part when needing to change the steel filter screen.
Furthermore, the middle part of the filter plate is provided with a through hole, correspondingly, the middle part of the steel filter screen is also provided with a through hole, and the edge of the through hole on the steel filter screen is welded with the filter plate.
The utility model discloses a technical scheme in, the filter screen of weaving with thick manganese steel strip replaces original rubber filter plate, can form the bump in filter plate both sides after thick manganese steel strip interweaves, also can form the aperture simultaneously, all can be used for the drainage to walk the water. Adopt the technical scheme of the utility model the water permeability is better, and the moisture content is lower after the mud cake dehydration, and the single advances mud volume and increases 20% than original, sexual valence ratio is higher. The initial replacement cost is low.
