Abstract
What the utility model discloses a kind of thermal power generation uses water filtering device, the conical screen comprising tank body, be located at the motor transmission mechanism outside described tank body and be located in described tank body, the large awl end of described conical screen is provided with blow-off pipe, the conelet end of described conical screen is provided with down blow pipe, the axis of described conical screen is provided with a shaft driven by described motor transmission mechanism, and the two ends of described shaft are bearing on the sliding bearing at described upper and lower blowdown pipe end place respectively.The utility model can blowdown easily automatically, and adopts the sliding bearing of high strength, and corrosion-resistant, smooth surface, can play lubrication well.
Description
Technical field
The utility model belongs to a kind of filter plant, is particularly useful for the filter plant in thermal power generation service water system.
Background technology
In system for application condenser equipment such as thermal power generation; all exist in water and have foreign material blocking pipe thus the problem that normally works of influential system; and existing sliding bearing in use can produce small wear particle; these wear particles can play lubrication to sliding bearing; but in heat-engine plant circulating water; under current constantly souring, wear particle can be flushed away, and does not therefore have lubrication to sliding bearing.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provide one can filtering contaminants, ensure water circulation system normal thermal power generation water filtering device.
For achieving the above object, the utility model adopts following technical proposals:
The use water filtering device of thermal power generation, the conical screen comprising tank body, be located at the motor transmission mechanism outside described tank body and be located in described tank body, the large awl end of described conical screen is provided with blow-off pipe, the conelet end of described conical screen is provided with down blow pipe, the axis of described conical screen is provided with a shaft driven by described motor transmission mechanism, and the two ends of described shaft are bearing on the large awl end of described conical screen and the sliding bearing at conelet end place respectively.
Described sliding bearing adopts YG series alloy steel, and its Rockwell hardness is 82 to 84.
Also comprise scraping plate mechanism, the side of described scraping plate mechanism is connected on described shaft, and opposite side is close to the wire side of described conical screen.
After adopting technique scheme, the utility model compared with prior art, tool has the following advantages: the utility model can blowdown easily automatically, and the foreign material being conducive to filtering are discharged rapidly, and adopts the sliding bearing of high strength, rigidity is strong, corrosion-resistant, do not have abrasion of particles and get off, smooth surface, lubrication can be played well, be mainly used in field of thermal power.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged diagram at the bearing place of sliding place at the A place of Fig. 1;
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figures 1 and 2, the use water filtering device of thermal power generation, the conical screen 3 comprising tank body 1, be located at the motor transmission mechanism 11 outside tank body 1 and be arranged in tank body 1, the large awl end of conical screen 3 is provided with blow-off pipe 15, the conelet end of conical screen 3 is provided with down blow pipe 4, the axis of conical screen 3 is provided with a shaft driven by motor transmission mechanism 11 13, one end of shaft 13 is bearing on the sliding bearing 16 of the large awl end of conical screen 3, and the other end of shaft 13 is bearing on the sliding bearing 5 of conical screen 3 conelet end.
Also be provided with scraping plate mechanism 12 in conical screen 3, the side of scraping plate mechanism 12 is connected on shaft 13, and opposite side is close to the wire side of conical screen 3.
During utility model works, it is inner that recirculated water enters conical screen 3 from the import of tank body 1, foreign material in recirculated water are blocked in the inner surface of conical screen 3, water is flowed out by the mesh of conical screen 3, when foreign material gather some at conical screen 3 inner surface, mesh eyes on conical screen 3 reduces, in filter screen, the pressure differential in outside increases, when pressure differential reaches predetermined value, motor 11 starts, scraping plate mechanism 12 is driven to rotate by transmission mechanism, the wire side of conical screen 3 is cleared up, it scrapes the foreign material assembled in wire side, and discharge respectively by upper blow-off pipe 15 and down blow pipe 4.
Because the utility model runs under specific application scenario, continue to use the problem that traditional sliding bearing can bring fretting wear serious, this is because traditional sliding bearing is generally the Rockwell hardness that surface is 20, the particle got off by wearing and tearing forms break-in oil film, if but in the alkalescence being used in seawater or the utility model thermal power generation or sour environment, current can wash away the particle worn and torn, and make surface form lubricating film, do not have lubrication.
Therefore the material of sliding bearing 5,16 of the present utility model adopts YG20 wolfram steel, and Rockwell hardness is 82-84HRC, and its hardness is high, is not easy wearing and tearing, can keeps smooth surface, therefore can play lubrication well, can also ensure that microorganism cannot grow simultaneously.
Sliding bearing rigidity of the present utility model is strong, and corrosion-resistant, intensity is high, does not have abrasion of particles and gets off, be mainly used in field of thermal power.
The above; be only the utility model preferably detailed description of the invention; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain of claim.
