[0036] 1 and the same fixed cover movable cover structure 2, only as an example of the structure of the fixed plate, of 2 to Figure 4 Shows a structure, comprising a cover plate body 8 is provided with a pressure relief valve on the cover body 8 and 9 harvesting assembly 10; the cover body 8 includes a square frame 11, mounted on the outer edge of the frame 11 a sealing member 4 and the upper sealing film mounted on the frame 12 and the lower sealing film 13; 11 in addition to the hinge side frame 1a is attached to the outer edge of the rest of the sealing body 4, the sealing member 4 has a shape from a plan view Kan; 4 comprises a sealing member the upper capsule holder 14, is connected with the capsule holder 14 with sealed capsules 15, the capsule holder 16 and the capsule holder 16 is connected with the lower fitting 17 in sealed capsules; sealed capsules on a capsule 15 with the lower seal 17 are arranged vertically, and sealing the capsule 15 and the outer lower edge 17 of sealed capsules in the same vertical line; the sealant 17 is slightly lower than the lower edge of the capsule under the sealing film 13; 13 sealing the entire lower surface of the sealing film frame 11; a sealing film the upper surface 12 of the sealing frame 11; 15 and the lower seal sealed capsules capsules were round cross-section 17, and a connector extending from the outside edge along which the corresponding connecting side of the capsule holder is connected by a locking bolt .
[0037] Follower means 6 includes a skimmer 22 and a current collector assembly oils oil contact assembly 22 through the collector tube 23 is fixed to the cover plate 8; collector tube 23 connected to an external apparatus skimmer; oil collector assembly 22 includes a fixed 11 is connected to frame 8 and cover plate 23 in contact with the collection tank 24 of the collector tube, extending from the catch tank 24 different horizontal length a plurality of link tube 25, the distal end 25 of each tube are connected by connecting elbow has a mounting receiving port 26; receiving port 26 has a wide mouth trumpet-shaped, the opening vertically upwardly, the square opening of the sealing plate 3 is reserved for inhibiting skimmer gap; various different skimmer oil recovery port 26 of the gap. Collector tube 23 in contact with the bottom 24 of the collection tank.
[0038] Close to the hinge plate 1 is fixed at the edge of the 1a is provided with two symmetrically arranged GABLE inner cover plate 11 connected to the frame 18, the connection between the two mating Renzi Jia achieved by a connecting rod 18; 18 symmetrically disposed on both GABLE a pulley 19; lead cables connected with a pulley 19 on the frame 1 and the movable cover 20.
[0039] Figure 1 to 4 Shows a square type enclosed inhibition recessed area cover plate 3 is fixed frame 1 and the movable cover plate 8 provided with elongated body 2 on the upper surface 21 lower than the recessed area 21 the sealing film 12; harvesting assembly 10 is provided in the recessed area 21, the harvesting assembly 10 through the cover body 8; wherein the structure comprises a harvesting assembly 10 connected thereto siphon water bucket and the water conduit is provided with aqueduct in the check valve, although the above-described configuration is not shown in the figures, but the siphon water bucket, and other components are co-ordinated with the mature part, we have a large number of mature product can be used directly purchasing.
[0040] 9 pressure relief valve is a check valve for releasing gas in the sewage tank, the rectangular lid 3 has been sealed against the suppression pool floating on the liquid surface;
[0041] Figure 5 Shows a schematic view of the structure of fitting the cesspool, as shown, to prevent dry sump when the device overall fall down into contact with the bottom of the pool bottom, damage to the device itself, therefore, inhibition of quad seal cover 3 and further a plurality of brackets provided on the inner wall surface of the sewage tank 28 is connected with a plurality of brackets 28 can be suppressed prismatic sealed lid 3 is fixed to the sewage tank horizontally, without contacting with the bottom.
