Abstract
A strong sewage-discharging secondary filter net includes a shell; the shell has an upper opening and a lower opening; the shell is provided with a filter core; the filter core is provided with a rotary shaft; the rotary shaft is connected with the rotary drive device arranged outside the shell; the side wall of the shell is provided with a sewage-discharging negative pressure chamber; the outside of the sewage-discharging negative pressure chamber is provided with a sewage-discharging opening; a rubber scraping plate is arranged between the four walls of the inner opening inwards of the sewage-discharging negative pressure chamber and the filter core; the rubber scraping plate on one side of the sewage-discharging negative pressure chamber is provided with a strong sewage-discharging steel wire brush. The steel wire brush is fixed between the rubber scraping plate and the side wall of the sewage-discharging negative pressure chamber and is fixed through a pressing plate. When the clearing of the sewage is reversed, the sewage-discharging opening is opened; then the negative pressure is formed in the sewage-discharging negative pressure chamber; the sewage on the outer wall of the filter core is discharged out through the sewage-discharging opening; the plastic film closely clinging to the filter core is scraped by the steel wire brush and is discharged out of the sewage-discharging opening along with the water flow; the filter core is easy to be cleared to achieve the index of the reversed clearing design; based on a plurality of times of field experiments, the utility model achieves the good effects and overcomes the difficulties that the plastic film is not easy to be cleared.
Description
Technical field
The utility model relates to steam power plant recirculated water is carried out the device that secondary filter purifies, the dirty secondary filter of particularly a kind of forced-ventilated.
Background technology
Secondary filter that steam power plant is used and ball cleaning apparatus are the assurances of operation unit operate as normal, in unit long-time running process, and the easy fouling of the cooling water pipe in its cooling system, and have dirt to stop up water pipe sometimes, cause unit output energy loss.Original secondary filter all is by the rubber slab blowdown; and our country pollutes that the most serious to have a kind of be plastic sheeting now; in plastic sheeting enters secondary filter; under the hydraulic pressure effect; be close on the filter screen, rubber flap is scraped to be got off at all, and the time one is long; directly influence the flow area of secondary filter, cause emergency shutdown sometimes.
Summary of the invention
The technical problems to be solved in the utility model is at the deficiencies in the prior art, has proposed a kind of dirty secondary filter of forced-ventilated that can remove plastic sheeting on the filter screen.
The technical problems to be solved in the utility model is achieved through the following technical solutions, the dirty secondary filter of a kind of forced-ventilated, it is provided with a housing, housing is provided with suitable for reading and end opening, filter core is housed in the housing, filter core is provided with a rotating shaft, the rotating shaft device of rotation driving outer with being located at housing joins, sidewall at housing is provided with blowdown negative pressure chamber, the outside of blowdown negative pressure chamber has sewage draining exit, be fixed with rubber flap between internal orifice wall that blowdown negative pressure chamber is inside and the filter core, be characterized in: the rubber flap place of a side of blowdown negative pressure chamber is provided with the dirty wire brush of forced-ventilated.
The technical problems to be solved in the utility model can also come by the following technical programs further to realize that the dirty wire brush of described forced-ventilated is fixed between rubber flap and the blowdown negative pressure chamber sidewall, and fixes by pressing plate.
The utility model is provided with the dirty wire brush of forced-ventilated at the rubber flap place of a side of blowdown negative pressure chamber, general filter core is for clockwise rotating, then wire brush is located at the left side of blowdown negative pressure chamber, when backwash is removed contamination, open sewage draining exit, then form negative pressure at blowdown negative pressure chamber place, the dirt of filter core outer wall is discharged by sewage draining exit, the plastic sheeting that is close on the filter core is scraped off by wire brush, discharges from sewage draining exit with current.Compared with prior art, the utility model can be cleaned out filter core easily, reaches the index of backwash design, through repeatedly field experiment, has obtained good effect, has overcome the not difficulty of easy-clear of plastic sheeting.

The specific embodiment
The dirty secondary filter of a kind of forced-ventilated, it is provided with a housing 6, housing 6 is provided with suitable for reading 4 and end opening 9, filter core 8 is housed in the housing 6, filter core 8 is provided with a rotating shaft 7, rotating shaft 7 is joined with the device of rotation driving 5 that is located at outside the housing 6, sidewall at housing 6 is provided with blowdown negative pressure chamber 3, the outside of blowdown negative pressure chamber 3 has sewage draining exit 2, be fixed with rubber flap 1 between internal orifice wall that blowdown negative pressure chamber 3 is inside and the filter core 8, the inside rubber flap 1 of blowdown negative pressure chamber 3 walls forms a circle, and suitable distance can be guaranteed to form enough negative pressure in the blowdown negative pressure chamber 3 between rubber flap 1 and the filter core 8, thereby dirt is peeled off from filter core 8.Rubber flap 1 place of one side of blowdown negative pressure chamber 3 is provided with the dirty wire brush 10 of forced-ventilated.The dirty wire brush 10 of forced-ventilated is fixed between rubber flap 1 and blowdown negative pressure chamber 3 sidewalls, and fixing by pressing plate 11.General filter core is for clockwise rotating, then wire brush 10 is located at the left side of blowdown negative pressure chamber 3, when backwash is removed contamination, open sewage draining exit, then form negative pressure at blowdown negative pressure chamber 3 places, the dirt of filter core 8 outer walls is discharged by sewage draining exit, and the plastic sheeting that is close on the filter core 8 is scraped off by wire brush 10, discharges from sewage draining exit with current.
