Description

The ceramic wastewater filter for installation

The utility model relates to a kind of filter.

Before the utility model, the existing industrial enterprise of China wastewater treatment equipment, great majority all are to build the natural sedimentation of several ponds, the round-robin that has, the discharging that has.In the process that recycles, there are problems, as Industrial Boiler, now all adopt gallet water curtain dust collector, chain furnace flush slag equipment, dedusting water and flushing cinder water collect in sedimentation basin, do not get off through contamination precipitations such as a lot of dusts of natural sedimentation, it is big to recycle pipe wear, the water pump loss is also big, changes one of pump, and enters gallet water curtain dust collector in three months that have, shower nozzle in the wearing and tearing deduster, cause water smoke not close, dust removing effects is poor, and black graceful son can fall, contaminated environment, discharging does not reach environmental requirement yet naturally.Also have other industrial wastewaters such as colliery mine water, need be treated, still do not reach multiplexing requirement, have only the nature discharging, have to waste water resource so greatly every day from underground water intaking.China is that a people is many, and ground is few, and how the country that water resource lacks solves using water wisely and listed China Party and government schedule example thing in.

The purpose of this utility model just provides a kind of device of effluent filter, thereby has solved the problem of industrial circulate water, has reached water-saving purpose.

Invention main points of the present utility model are that it is made up of three parts: the one, and filter mantle, pore radius is between the 50--100 micron, be suitable for and handle various industrial wastewaters, filter mantle by a headband at the bottom of, opening and two open ends are straight-through to be formed, the filter mantle external diameter is at φ 200-250mm, and internal diameter is at φ 140-180mm, filter mantle length (height) 1000-1100mm; The 2nd, filter through sedimentation basin (just utilizing), filtering ponds, clear water reserviors, pump house, overflow ditch as original, be communicated with steps such as grinding stone water dust scrubber gutter and flushing cinder ditch; The 3rd, filter mantle, band bottom opening pipe and opening straight pipe couple together, and are fixed in the filtering ponds on the prefabricated connection crossbeam, seal filter mantle is strict with special clay, make filter mantle and are connected crossbeam and form an integral body.

Sedimentation basin is generally formed by two to four, and the sedimentation basin degree of depth is 4m, and the sedimentation basin size is by the decision of the industrial enterprise waste water water yield, general 4 * 4m or 6 * 6m, and 8 * 8m, specifically by landform, the water yield and decide, sedimentation basin generally designs to be contained car and digs ash (mud) automatically and install.

Filtering ponds are the rectangle pond, size is handled the water yield according to industrial enterprise and is decided, the degree of depth guarantees on the filter mantle the above water normal pressure of 1m is arranged, filtering ponds are interior by prefabricated fair-faced ditch, reserve on the clear water ditch filter mantle circular hole is installed, fixedly filter mantle connects crossbeam and cleaning sludge sump composition; Connect crossbeam and reserve circular hole connection filter mantle, it is concentric require to reserve on circular hole and time prefabricated fair-faced ditch circular hole, prefabricated reservation circular hole quantity on crossbeam quantity and the crossbeam, decide according to handling the water yield, distance is 800-1000mm with the circular hole center between the crossbeam, is 300-350mm with the circular hole center between the circular hole on the crossbeam; Crossbeam and following clear water ditch platform clear height 900-1000mm, the crossbeam width is 360-410mm, crossbeam thickness is 200-250mm, crossbeam width and following clear water ditch platform symmetry, clear water ditch podium level is 350mm, the sludge sump width is 1000mm, and the degree of depth is 700mm under the clear water ditch platform, and the mud groove tilts 8.75% with the outlet of clear water ditch to the sludge sump direction between the clear water ditch platform.

Clear water reserviors, clear water reserviors are loaded onto valve disc from the filtering ponds clear water output so that later on mechanical backlash wash standby.Valve disc is at the outstanding 150mm of clear water reserviors, height and base plate headroom 350mm.

The design of filtering ponds and clear water reserviors, salable for saving the area, do his usefulness above, also can open wide, but require the clear water reserviors sealing, guarantee water quality.

Advantage of the present utility model is:

1. the natural filtration usefulness that do not cost in service because of it is to be sealed in the filtering ponds by filter mantle, is utilized water normal pressure natural filtration more than 1 meter.

2. the utility model adapts to the various wastewater treatments of industrial enterprise, can handle the crystal's degree and the water yield according to industrial enterprise's requirement, and adjust the micropore size of filter mantle, reaches the quality and the quantity of water.

3. the filtering ponds filter mantle by up and down two be connected on the filtering ponds crossbeam and (promptly go up root and be band bottom opening pipe and following root opening straight pipe), connector through special clay sealing, forms integral body with crossbeam in the middle of crossbeam, there are not bonding mouthful of breakage or solution cavity, solid and reliable.

4. utilize contrast backwash of clear water reserviors hydraulic pressure or the artificial backwash of machinery pressurization, extend working time, shorten wash number.

5. the life-span long, general service life all within 10 years, promptly use 10 years after, filter mantle is saturated, directly changes filter mantle just, need not reinvest other facilities.

6. maintenance cost is few, only need 1 year or longer time cleaning are just, method for cleaning is simple, only need close inlet gate, drain clear water reserviors then, make the exposed back of filter mantle just, make mud, flow into sludge sump naturally along sludge sump with the giant surface washing, take away with slush pump then, after cleaning out, fill clear water reserviors, utilize clear water reserviors contrast recoil filter mantle with running water (clear water), as year number of a specified duration excessively, the method lost efficacy, and adopted 3 kilograms of pressure of machinery again, artificial backwash.

The utility model is suitable for the various wastewater treatments of industrial enterprise, as boiler water by removing dust, flushing cinder water; The colliery mine water is after preliminary treatment, and in-depth is handled; After the preliminary treatment of smelter waste water, in-depth is handled; And other enterprises are through after not reaching multiplexing requirement or emission request, just reaching requirement as long as handle the back through the utility model after the preliminary treatment.
