Improvement of sewage treatment of kitchen garbage trucks
The secondary pollution treatment of sanitation vehicles has been a major problem, even if it is a compact garbage truck, leakage, air leakage, water leakage has been unable to eliminate. In the three leaks of the sanitation vehicle, the most inadequate treatment is water leakage - the sewage leakage of the garbage truck often causes pollution to the road surface, and the main road of the city will be stinked by it. The problem of compact garbage trucks is even more serious. In order to deal with the sewage treatment problem of compact garbage trucks, it is necessary to find a way to add the sewage tank volume and deal with the collection and discharge of sewage.
Adding the volume of sewage tank and increasing the sewage tank is the primary way to deal with sewage outflow. The sewage tank is related to the filler. When considering the cooperation space between the filler and the body, the filler can not occupy too much space and the increase of the sewage tank volume is limited. The collection of sewage by the compact garbage truck can be reflected in the planning of the sewage tank.
There are generally two ways: One is to set the sewage tank in the lower part of the front of the filler, which can make better use of the space between the filler and the lower part of the body, and also reduce the rear suspension of the vehicle and increase the departure Angle, but the volume of the sewage tank is small, and the expansion potential is small. The other is to set the sewage tank under the bottom plate of the filler, abandon the space between the filler and the lower part of the body, and increase the rear suspension of the vehicle and reduce the departure Angle.
The capacity of the sewage tank is large, and the expansion potential is also large. In the second plan, the expansion method of the sewage tank is to use part of the space of the filler to collect sewage. For cars of about 5t, the filling space of the previous sewage tank and the filler is independent from each other. When the use of filling space is not considered, the volume of the sewage tank is only 120L, which cannot fully meet the requirements of sewage collection, but 4 to 5 round holes of about 20mm are opened horizontally at the lowest point of the bottom plate of the filling device.
After connecting the two Spaces, the volume of the sewage tank is more than doubled, and the pollution collection can be greatly added. In contrast, the first type of plan sewage tank volume is limited to between 60 and 80 L, and it is often loaded with garbage while flowing sewage. In order to reduce the leakage during the garbage truck cleaning, it is necessary to increase the sewage collection ability, make full use of the existing possible water storage space of garbage trucks, and plan temporary water storage equipment.
