[0002] With the rapid development of China's economic construction and the advancement of the urbanization process, the discharge of domestic sewage in urban communities has increased the burden on sewage treatment plants. Domestic sewage is the wastewater discharged in residents' daily lives, mainly from residential buildings and public buildings, such as residences, government agencies, schools, hospitals, stores, public places, and the toilets of industrial enterprises. The pollutants contained in domestic sewage are mainly organic substances and a large number of pathogenic microorganisms. In addition, the residues in the septic tanks of some living communities will flow directly into the sewage pipe network along with the sewage discharge, causing blockages in the sewage pipes, resulting in sewage overflowing everywhere and affecting the urban sanitation environment.

[0003] To solve this objective situation, the existing technology has developed vehicles with purification devices, which are used to separate sewage and dirt. However, the existing mobile sewage treatment machines are all intermittent in processing, that is, when the sewage tank uses a vacuum pump to pump sewage, the subsequent sewage treatment steps need to stop. When the sewage tank is full, the subsequent operations are started. Moreover, the solid substances in the sewage are also prone to clogging the pipes, resulting in low sewage treatment efficiency.

[0025] Refer to Figure 1, A sewage suction and purification vehicle, comprising a vehicle head 1, a vehicle board 2, a water pumping mechanism 3, a crushing mechanism 4, a separation mechanism 5, and a sewage tank 6. One end of the vehicle board 2 in its length direction is fixedly connected to the vehicle head 1. The water pumping mechanism 3, the crushing mechanism 4, the separation mechanism 5, and the sewage tank 6 are all arranged on the vehicle board 2 and are spaced along the length direction of the vehicle board 2. The water pumping mechanism 3 is arranged at one end of the vehicle board 2 in its length direction and away from the vehicle head 1, and is used for sucking sewage. The crushing mechanism 4 is arranged at one end of the vehicle board 2 close to the water pumping mechanism 3, and is used for crushing solid substances in the sewage. The separation mechanism 5 is arranged on the vehicle board 2 on the side of the crushing mechanism 4 close to the vehicle head 1, and is used for solid-liquid separation of the sewage passing through the crushing mechanism 4. The sewage tank 6 is hollow inside, and the sewage tank 6 is fixedly arranged on the vehicle board 2 on the side of the separation mechanism 5 close to the vehicle head 1, and is used for storing sewage.

[0026] During use, first, the operator moves the purification vehicle to the destination, starts the water pumping mechanism 3 to suck sewage, and then starts the crushing mechanism 4 and the separation mechanism 5, which can crush the solid substances in the sewage and perform solid-liquid separation. Finally, the sewage enters the sewage tank 6 for storage.

[0027] Refer to Figure 1 and Figure 2 , The water pumping mechanism 3 includes a mounting plate 31, a screw 32, a water pumping motor 33, a limiting rod 34, a slider 35, and a sewage suction pump 36. The number of mounting plates 31 is two, and the two mounting plates 31 are symmetrically and fixedly arranged at both ends of the vehicle board 2 in its width direction. The screw 32 is arranged between the two mounting plates 31 along the width direction of the vehicle board 2, and both ends of the screw 32 are rotatably connected to the two mounting plates 31 respectively. The water pumping motor 33 is fixedly arranged on one of the mounting plates 31, and the output shaft of the water pumping motor 33 passes through the mounting plate 31 and is rotatably connected thereto.

[0028] During use, the operator can adjust the position of the sewage pump 36 according to the position of the sewage, and start the pumping motor 33. The pumping motor 33 can drive the screw 32 to rotate. Due to the threaded connection between the slider 35 and the screw 32 and the limiting effect of the limiting rod 34, the slider 35 can only move along the length direction of the screw 32, thereby realizing the adjustment of the position of the sewage pump 36, which is more convenient for sucking sewage.

[0029] Referring to Figure 1 and Figure 3 and referring again to Figure 4 The crushing mechanism 4 includes a crushing box 41, a stirring motor 42, a stirring shaft 43, fixed rods 44, a fixed disk 45, and magnets 46. The crushing box 41 is fixedly arranged on the vehicle plate 2 and is arranged in a cylindrical shape with a hollow interior. One end of the water outlet pipe 38 far from the sewage pump 36 is fixedly connected to and communicates with the crushing box 41.

One end of the fixed disk 45 close to the stirring shaft 43 is inclined downward and is open near the stirring shaft 43, and friction tooth marks 451 meshing with the friction protrusions 441 are fixedly arranged on the fixed disk 45. The magnets 46 are arranged in a circular shape. The number of the magnets 46 is multiple, and the multiple magnets 46 are all fixedly arranged on the bottom surface of the crushing box 41.

The preliminarily pulverized solid matter will fall on the fixed disk 45 and be further ground by the friction protrusions 441. The ground solid matter will enter the bottom of the pulverizing box 41 along one end of the fixed disk 45 close to the stirring shaft 43. At this time, the magnet 46 can also adsorb the iron in the sewage. At the same time, the first water pump 49 is started, and the sewage passing through the pulverizing box 41 can be sucked to the separation mechanism 5 for separation.

[0031] Refer to Figure 1 and Figure 5 As shown in FIGS. 5 and 6, the separation mechanism 5 includes a separation box 51, a first filter plate 52, and a second filter plate 53. The separation box 51 is hollow inside and has an open top, and a cover plate 54 is hinged to the top of the separation box 51.
