Description

Second grade rough filtration unit for washing and sweeping vehicle and rough filtration unit, sewage treatment unit, sewage energy recovery system and washing and sweeping vehicle with second grade rough filtration unit Technical Field The invention relates to the field of washing and sweeping vehicles, in particular to a secondary rough filtration unit for a washing and sweeping vehicle, a rough filtration unit with the secondary rough filtration unit, a sewage treatment unit, a sewage energy recovery system and a washing and sweeping vehicle. Background At present, the 18-ton pure electric washing and sweeping vehicle on the market fully loads 8 tons of clean water in one operation and can continuously operate for about 1 hour. The chassis battery is about 300 degrees of electric quantity, and can meet the continuous operation of 6 hours. When the clear water is used up, the vehicle needs to return to the parking lot to take water, and when the electric quantity is used up, the operation is stopped and the vehicle returns to charge. Therefore, the total effective operation time of the 18-ton pure electric washing and sweeping vehicle is less than 4 hours. The method mainly increases the battery capacity and the clean water tank capacity to improve the cruising ability. First, increasing the battery power means that the battery becomes large in size and heavy in weight, not only encroaches on the installation space of other systems of the washing and sweeping vehicle, but also the increased battery weight additionally consumes power. Secondly, increasing the volume of the clean water tank increases the volume of the clean water tank, and occupies a larger space, and the increase of the volume of the clean water tank has little effect on increasing the duration of continuous operation. In order to increase the working duration of the washing and sweeping vehicle, a sewage recovery function is added in a conventional treatment mode, and a sewage filtering device is necessarily needed when the sewage recovery function of the washing and sweeping vehicle is used at present, wherein the sewage filtering device generally comprises coarse filtering equipment, and the conventional coarse filtering equipment comprises a fixed filter screen, a vibrating screen or a static filter cylinder and the like. Although the equipment has a simple structure, the surface of the filter screen is extremely easy to be covered and blocked by sundries, so that the filtering efficiency is rapidly reduced, the water inlet pressure is increased, and even the system is stopped. And traditional coarse filtration units are mostly single-stage filtration, and impurities with all sizes are borne by a single filter layer, so that the filter layer is saturated rapidly, frequent cleaning or replacement is needed, and the maintenance cost and the downtime of equipment are increased. The suction device of the washing and sweeping vehicle, the washing and sweeping vehicle and the operation method of the washing and sweeping vehicle disclosed in the prior patent CN 118257223A do not clearly disclose the technical contents for solving the technical problems. Therefore, in order to improve or solve at least one of the above technical problems, a filtering device is needed to assist in recycling the sewage of the washing and sweeping vehicle. Disclosure of Invention The invention aims to provide a secondary rough filtering unit for a washing and sweeping vehicle, which has high screening efficiency and can avoid screen blockage. In order to achieve the aim, the invention adopts the technical proposal that, The secondary coarse filtration unit for the washing and sweeping vehicle comprises a secondary filtration tank, a secondary coarse filtration inner cavity is formed in the secondary filtration tank in a hollow mode, a secondary liquid outlet and a secondary liquid inlet are formed in the secondary filtration tank, a discharge chute is formed in the secondary filtration tank, a rotary filter cartridge is arranged in the secondary filtration tank, the rotary filter cartridge is connected with a driving mechanism capable of driving the rotary filter cartridge to rotate, the secondary liquid inlet is communicated with the rotary filter cartridge, and the rotary filter cartridge is communicated with the discharge chute. The secondary rough filtration inner cavity is internally provided with a separation baffle plate, the separation baffle plate divides the secondary rough filtration inner cavity into a first cavity and a second cavity, the rotary filter cartridge is arranged in the first cavity, the driving mechanism is arranged in the second cavity, the driving mechanism comprises a first motor connected to the secondary filtration box, and the first motor is connected with the rotary filter cartridge through a transmission unit. The rotary filter cylinder comprises a plurality of single filter cylinders, wherein each single filter cylinder is coaxia
