Abstract
The invention provides a shellfish trapping device which comprises a left shell, a right shell and a filter screen, wherein the left shell is connected with the right shell by a bolt; the filter screen is arranged between the left shell and the right shell; the filter screen is in a cone shape; a center shaft is arranged at the axis of the filter screen; a tapered trapping pipe is arranged under the filter screen and clings to the filter screen; the trapping pipe is fixedly connected with the center shaft by a connecting rod; a blow-off pipe passes through the right shell; a driving device is arranged on the blow-off pipe at the outer side of the right shell; the blow-off pipe is connected with the trapping pipe by a connecting shaft; the blow-off pipe and the center shaft are arranged on the same axis; a press plate is arranged above the filter screen; the press plate is connected with the center shaft by a swing arm and a key; the press plate is provided with a roller wheel which is contacted with the filter screen; and the left shell and the right shell are respectively and internally lined with a layer of rubber. The shellfish trapping device is good in filtering effect and long in service life.
Description
Technical field
The present invention relates to a kind of filter, particularly relate to a kind of shellfish catcher with cleaning and blowdown apparatus.
Background technology
Shellfish catcher is mainly used in the safe service water system of SEC of coastal nuclear power plant, fore filter as the SEC/RRT heat-exchangers of the plate type, be used for filtering biological and other impurity of seashells, in order to avoid shellfish is attached to follow-up equipment and follow-up equipment is caused damage.The employed shellfish catcher in power station mostly adopts the form of strainer filtering at present, and shellfish is attached on the filter screen and grows, and filter screen easily stops up, poor filtration effect, and service life is short.
Summary of the invention
Easily stop up in order to overcome existing shellfish catcher filter screen, poor filtration effect, the deficiency that service life is short the invention provides a kind of shellfish catcher.
The technical solution adopted for the present invention to solve the technical problems is a kind of shellfish catcher, comprise left shell, right shell body, filter screen, left shell and right shell body are bolted, filter screen is installed between left shell and the right shell body, filter screen is taper, 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 with by connecting rod with axis, also have a blow-off pipe to pass right shell body, blow-off pipe in the right shell body outside is equipped with drive unit, and blow-off pipe is connected by 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 by 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 invention has the beneficial effects as follows to adopt filter screen regularly cleaned and blowdown, avoid shellfish to be attached on the filter screen and grow that good filtration effect adopts the structure of casing lining rubber in addition, avoids medium and the direct of housing to contact long service life.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
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 catcher, comprise left shell 1, right shell body 11, filter screen 8, left shell 1 is bolted with right shell body 11, filter screen 8 is installed between left shell 1 and the right shell body 11, filter screen 8 is taper, an axis 9 is equipped with at the axis place of filter screen 8, below filter screen 8, be close to filter screen 8 places the trap tube 6 of taper is housed, trap tube 6 is fixedly connected with by connecting rod 7 with axis 9, also has a blow-off pipe 13 to pass right shell body 11, and the blow-off pipe 13 in right shell body 11 outsides is equipped with drive unit 12, blow-off pipe 13 is connected by 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 by 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, makes medium and left shell 1 and right shell body 11 isolation, the service life of improving equipment.
During use, the water source of filtered enters from the lower end of right shell body 11, and the water purification after filter screen 8 filters enters follow-up equipment through left shell 1 left end, the 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 rushed 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 trap tube 6 synchronous rotaries.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.
