Background technology
Along with the raising of living standards of the people, the output of rubbish is increasing, and simultaneously urban land is nervous, rubbish terminal processes place far from city more and more away from, so need to set up refuse transfer station, transport with transfer car(buggy) after the rubbish of collection is compressed.The rubbish container of transfer car(buggy) is provided with the back door of discharging, usually has rubber strip to seal between back door and casing, but due to following several respects reason cause sealing difficulty:
1) manufacturing reason causes the binding face of sealing band to be uneven, thus causes poorly sealed;
2) mechanism kinematic that back door is closed makes sealing band wear and tear;
3) binding face of sealing band is made to be mingled with foreign matter when discharging or rubbish vanning;
4) component of refuse is complicated, and sealing band is perishable, seriously aging after using a period of time.
The poorly sealed meeting of sealing arrangement causes rubbish in transport process, have Leachate site water clock, cause the secondary pollution to environment, the smell pollution air that Leachate site produces, road needs cleaning, virtually too increase the labour intensity of sanitationman, waste limited resources.
At present, sealing device for refuse vehicle mainly contains following two schemes:
Mode one:
As depicted in figs. 1 and 2, be embedded with individual layer sealing band between back door of rubbish bin 1 and casing 2, arrange water receiving tank 3 below back door 2, the sewage collecting of drippage is transported to foul water tank 5 bottom car by distribution tube 4 by water receiving tank 3.
There is following defect in this mode:
1) although water receiving tank 3 has stopped sewage, avoid sewage water clock on road, water receiving tank is exposed, and sewage foul smell distributes still contaminated environment, and the water receiving tank that spot is full of stains or spots also affects attractive in appearance;
2) water receiving tank 3 is high with foul water tank 5 drop, thus foul water tank 5 must be arranged rearward, limits the position of foul water tank 5, decreases the volume of foul water tank 5;
3), during rubbish vanning, compressor docks with transfer car(buggy), and water receiving tank 3 together need open and close along with back door, easily damages; Further, distribution tube 4 and foul water tank 5 need to disconnect, and in the opening process of back door, sewage remaining in water receiving tank 3 is easily dropped in impact station environment in transfer point.
Mode two:
The faying face at casing and back door is provided with double-layer seal rings to realize bilge water resisting seepage.
There is following defect in this mode:
The setting of double-layer seal rings, fundamentally can not eliminate the seepage of sewage, and between two seals circle, sewage residual quantity increases, and after hydraulic pressure reaches certain value, sewage still has seepage, can not really effectively seal.
