Description
Technical field
The utility model relates to a kind of filter, particularly relates to a kind of shellfish trap with cleaning and blowdown apparatus.
Background technology
The shellfish trap is mainly used in the SEC safety service water system of coastal nuclear power plant; Fore filter as the SEC/RRT heat-exchangers of the plate type; Be used to filter biological and other impurity of seashells, in order to avoid shellfish causes damage to follow-up equipment attached to follow-up equipment.The employed shellfish trap in power station mostly adopts the form of strainer filtering at present, and shellfish is attached to growing on the filter screen, and filter screen is prone to stop up, poor filtration effect, and service life is short.
Summary of the invention
Be prone to stop up in order to overcome existing shellfish trap filter screen, poor filtration effect, the deficiency that service life is short, the utility model provides a kind of shellfish trap.
It is a kind of shellfish trap that the utility model solves the technical scheme that its technical problem adopted, and comprises left shell, right shell body, filter screen, and left shell is connected through bolt with right shell body; Filter screen is installed between left shell and the right shell body, and filter screen is taper, and an axis is equipped with at the axis place of filter screen; Below filter screen, be close to the filter screen place trap tube of taper is housed; Trap tube is fixedly connected through connecting rod with axis, also has a blow-off pipe to pass right shell body, on the blow-off pipe in the right shell body outside, drive unit is housed; Blow-off pipe is connected through connecting axle with trap tube, and blow-off pipe and axis are positioned on the same axis.
One pressing plate also is housed above filter screen, and pressing plate is fixedly connected with key through swing arm with axis, and roller is housed on the pressing plate, and roller contacts with filter screen.Left shell and right shell body inner chamber also are lined with one deck rubber.
The beneficial effect of the utility model is to adopt filter screen is regularly cleaned and blowdown, avoids shellfish attached to growing on the filter screen, and good filtration effect adopts housing liner rubber structure in addition, avoids medium and the direct of housing to contact long service life.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Fig. 1 is the structural map of present embodiment
Among the figure: 1. left shell; 2. swing arm; 3. pressing plate; 4. key; 5. roller; 6. trap tube; 7. connecting rod; 8. filter screen; 9. axis; 10. connecting axle; 11. right shell body; 12. drive unit; 13. blow-off pipe; 14. rubber.
The specific embodiment
As shown in Figure 1, a kind of shellfish trap comprises left shell 1, right shell body 11, filter screen 8; Left shell 1 and right shell body 11 are connected through bolt, and filter screen 8 is installed between left shell 1 and the right shell body 11, and filter screen 8 is taper; An axis 9 is equipped with at the axis place of filter screen 8, below filter screen 8, is close to the trap tube 6 that taper is equipped with at filter screen 8 places, and trap tube 6 is fixedly connected through connecting rod 7 with axis 9; Also have a blow-off pipe 13 to pass right shell body 11; On the blow-off pipe 13 in right shell body 11 outsides, drive unit 12 is housed, blow-off pipe 13 is connected through connecting axle 10 with trap tube 6, and blow-off pipe 13 is positioned on the same axis with axis 9.One pressing plate 3 also is housed above filter screen 8, and pressing plate 3 is fixedly connected with key 4 through swing arm 2 with axis 9, and roller 5 is housed on the pressing plate 3, and roller 5 contacts with filter screen 8.Left shell 1 also is lined with one deck rubber 14 with right shell body 11 inner chambers, and medium and left shell 1 and right shell body 11 are isolated, and improves the service life of equipment.
During use, the water source of filtered gets into from the lower end of right shell body 11, and the water purification after filter screen 8 filters gets into follow-up equipment through left shell 1 left end; Foreign material such as shellfish are trapped in the lower surface of filter screen 8; Along with the increase of foreign material, the filtration water yield will be reduced, filtration pressure difference increases.This moment, drive unit 12 drive trap tubes 6 were close to filter screen 8 around axis 9 rotations, and water purification flows to lower surface by the upper surface of filter screen 8, and the foreign material that are attached to filter screen 8 lower surfaces are dashed from filter screen 8, discharges through trap tube 6, connecting rod 7, blow-off pipe 13.Blow-off pipe 13 is positioned at same axis with axis 9, makes pressing plate 3, roller 5 paste filter screen 8 and rotates synchronously with trap tube 6.Pressing plate 3, roller 5 are to guarantee that filter screen 8 does not deform and is shifted because of the scraping of trap tube 6.
