Improvement of sewage treatment for kitchen garbage truck
The secondary pollution treatment of sanitation vehicles has been a big problem, even if it is a compact garbage truck, slag leakage, air leakage, water leakage has been unable to eradicate. In the sanitation car of the three leakage of the most inadequate treatment is water leakage - garbage truck sewage leakage often constitutes pollution to the road, the city's first road will be made to stink. And the problem of compact garbage trucks is becoming more severe. In order to deal with the sewage treatment problem of compressed garbage truck, it is necessary to find ways to add the volume of sewage tank, and deal with the collection and discharge of sewage.
Increasing the volume of sewage tank is the primary way to deal with sewage outflow. The sewage tank is related to the filling device. When considering the cooperation space between the filling device and the box body, the filling device should not occupy too much space and the increase of the sewage tank volume is restricted. The collection of sewage by the compact garbage truck can be reflected in the planning of the sewage tank.
There are generally two approaches: One is to set the sewage tank in the front lower part of the filling device, which can make better use of the space between the filling device and the lower part of the car body, and also reduce the rear suspension of the vehicle and increase the departure Angle, but the sewage tank volume is small, and the expansion potential is small. The other is to set the sewage tank under the bottom plate of the filling device, discard the space between the filling device and the lower part of the car body, and together increase the rear suspension of the vehicle and reduce the departure Angle.
The capacity of the sewage tank is large and the capacity expansion potential is also large. In the second plan, the capacity expansion method of the sewage tank is to use part of the space of the filling device for sewage collection. For the car about 5t, the previous sewage tank and the filling space of the filler are independent from each other. Without considering the use of filling space, the volume of the sewage tank is only 120L, which cannot fully satisfy the requirements of sewage collection. However, 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 expanded by more than one times, and the pollution collection can be greatly added. In contrast, the sewage tank of the first scheme is limited to a volume of 60 to 80 L, which is often filled with garbage and sewage flow. In order to reduce the leakage during garbage truck cleaning, it is necessary to increase the sewage collection ability, make full use of the existing potential water storage space of garbage truck, and plan temporary water storage equipment.
