Air-tight seal type garbage transfer station rubbish storage case
Technical field
The present invention relates to refuse disposal system, be specifically related to a kind of air-tight seal type garbage transfer station rubbish storage case.
Background technology
Garbage transfer stands in the waste transportation process, rubbish storage case back door is closed, due to rubbish storage case chamber door and casing employing separate type, easily cause sewage to leak outside, the sewage that contains in a large number the objectionable impuritiess such as organic matter, nitrite, sulfide, ferrous salt directly leaks into outside casing, and be showered on ground, enlarge contaminated area, cause the secondary pollution to environment such as road, air; And the casing of prior art and the sealing band hardness between chamber door are excessive, realize that by deflection sealing can't produce a desired effect at all, and, due to work under bad environment, sealing band, because of easily fatigue damage by compression, can't meet seal request.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the shortcoming existed in prior art, providing a kind of can transport the sewage of rubbish and generation thereof together neatly, eliminate the transport process effluent seepage, drench, spill, pollution again to environment, the air-tight seal type garbage transfer station rubbish storage case of minimizing to the environment repeated pollution, the seal request while meeting waste transportation.
Technical matters of the present invention is to realize by following technical scheme.Garbage transfer station comprises casing and chamber door with the rubbish storage case, casing and chamber door top are connected through the hinge, bottom connects by locking device, locking device is comprised of hydraulic ram and connecting arm, piston rod rod end on hydraulic ram and connecting arm one end are hinged on the set pin be positioned on chamber door, the other end and rubbish storage box body are affixed, it is characterized in that casing and chamber door faying face also are provided with sealed air cushion; Sealed air cushion inside is filled with air; Sealed air cushion top has the air cushion sealing.
Beneficial effect of the present invention: air-tight seal type garbage transfer station rubbish storage case, utilization is filled with the deflection of air and realizes sealing, make casing and chamber door in conjunction with rear gap evenly and change little, eradicate the leakage phenomenon of spilling of sewage, eliminate the again pollution of garbage leachate to environment, in transportation, rubbish is all the time in sealing state.
The accompanying drawing explanation
Fig. 1 is structural front view of the present invention;
Fig. 2 is section-drawing of the present invention;
In figure 1, casing 2, chamber door 3, latching device 4, sealed air cushion 5, air cushion sealing 6, hydraulic ram 7, connecting arm 8, hinge 9, set pin.
The specific embodiment
As scheme as shown in l, Fig. 2, garbage transfer station of the present invention rubbish storage case, comprise casing 1 and chamber door 2, casing 1 is connected by hinge 8 with chamber door 2 tops, bottom connects by locking device 3, locking device 3 is comprised of hydraulic ram 6 and connecting arm 7, piston rod rod end on hydraulic ram 6 and connecting arm 7 one ends are hinged on the set pin 9 be positioned on chamber door, the other end and rubbish storage box body 1 are affixed, casing 1 and chamber door 2 faying faces also are provided with sealed air cushion 4, sealed air cushion 4 inside are filled with water, and sealed air cushion 4 tops have air cushion sealing 5.
Garbage transfer station of the present invention is adjustable with rubbish storage case sealed air cushion pressure, be divided into two operation process of opening and closing, opening process: under the effect of pressure oil, pressure oil enters the rodless cavity of hydraulic ram 6, piston rod moves forward, the company's of promotion chamber door 2 conter clockwises rotate up, and chamber door 2 is thrown off and put in place with the faying face of casing 1, and opening process finishes; Closing process: when pressure oil enters the rod chamber of hydraulic ram 6, due to the effect of gravity, chamber door 2 is around its center of gyration clickwise, the rod end of hydraulic ram 6 retraction.Chamber door 2 engages with casing 1, and sealed air cushion 4 is compressed.Garbage transfer station of the present invention is with the rubbish storage case through service testing, and sealing effectiveness is good, has thoroughly solved the secondary environmental pollution problem in the rubbish shipment.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present invention is described; but be not limiting the scope of the invention; one of ordinary skill in the art should be understood that; on the basis of technical scheme of the present invention, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection scope of the present invention.
