However, it has the following disadvantages: when the device is in use, the filter grid is in a stationary state, and blockage may occur during sludge filtering, thereby reducing the overall treatment effect of the device. Utility Model Content

[0021] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, an ozone disinfection device for a cleaning and suction sewage truck includes a sludge tank 1, which is arranged on the left side of the outer wall of a clean water tank 2, and a sewage suction pipe 3 is fixed to the top surface of the clean water tank 2, and a sewage suction head 4 is fixed to one end of the sewage suction pipe 3. A vacuum pump 5 is provided on the left side of the outer wall of the sludge tank 1, and an air intake pipe 6 is fixed between the vacuum pump 5 and the sludge tank 1. A mounting hole 7 is provided on the top surface of the sludge tank 1, and a filter grille 8 is detachably provided inside the mounting hole 7. A mounting plate 9 is fixed to the top surface of the filter grille 8, and a vibration motor 10 is fixed to the top surface of the mounting plate 9. A sewage pump 11 is provided on the right side of the outer wall of the sludge tank 1, and a first connecting pipe is fixed between the sewage pump 11 and the sludge tank 1. A cyclone 12 is provided on the right side of 11, and a second connecting pipe is fixedly connected between the cyclone 12 and the sewage pump 11, a third connecting pipe is fixedly connected between the cyclone 12 and the clean water tank 2, a sewage pipe 13 is fixedly connected between the sludge tank 1 and the clean water tank 2, a mixing pump 14 is provided below the clean water tank 2, two delivery pipes are fixedly connected between the mixing pump 14 and the clean water tank 2, an ozone generator 15 is provided below the mixing pump 14, a first mounting pipe is fixedly connected between the ozone generator 15 and the mixing pump 14, a high-pressure water pump 16 is provided below the clean water tank 2, a second mounting pipe is fixedly connected between the high-pressure water pump 16 and the clean water tank 2, and a nozzle 17 is fixed at the output end of the high-pressure water pump 16.

[0023] During use, the staff first starts the vacuum pump 5, which quickly draws the inside of the sludge tank 1 into a negative pressure state, and then pushes the suction head 4 deep into the sewer, and uses the negative pressure suction in the sludge tank 1 to smoothly suck the sludge into the sludge tank 1 through the suction pipe 3; after the sludge enters the tank, it is initially filtered by the filter grid 8, and large-sized sludge particles are effectively intercepted and retained in the tank, while fine mixed water continues to flow. At this time, the vibration motor 10 is started, which drives the mounting plate 9 and the filter grid 8 to produce slight vibration, effectively preventing the clogging of the filter grid 8; the filtered mixed water is then extracted by the sewage pump 11 and sent to the cyclone 12 through the first connecting pipe for solid-liquid separation. Under the action of the cyclone 12, the clean water and solid impurities are effectively separated, and the clean water flows into the clean water tank 2 for storage through the third connecting pipe, while the solid impurities are discharged through the sewage tank. The pipe 13 flows back to the sludge tank 1 and continues to participate in the filtration cycle; when the clean water in the clean water tank 2 needs to be disinfected, the staff starts the mixing pump 14, the mixing pump 14 pumps out the clean water in the clean water tank 2 and sends it into the mixing pump 14 through the delivery pipe. At the same time, the ozone generator 15 starts working, and the generated ozone enters the mixing pump 14 through the first installation pipe and is fully mixed with the clean water. The mixed ozone water is then pumped back to the clean water tank 2 through the delivery pipe. When the ozone concentration in the clean water tank 2 reaches the preset disinfection standard, the disinfection process is completed; finally, when cleaning the sewer, the staff starts the high-pressure water pump 16, the high-pressure water pump 16 pumps out the disinfected clean water in the clean water tank 2, and sends it into the high-pressure water pump 16 through the second installation pipe for pressurization. The pressurized clean water is sprayed out through the nozzle 17 in the form of high-pressure water flow to thoroughly clean the sewer.

[0024] The mixing pump 14 and the ozone generator 15 are used to disinfect the clean water, and the mounting plate 9 and the vibration motor 10 can make the filter grid 8 vibrate, thereby preventing blockage during sludge filtering, thereby improving the overall treatment effect of the device.

[0025] like Figure 1 、 Figure 2 and Figure 4 As shown, a check valve 18 is provided between the sludge tank 1 and the air inlet pipe 6 .

[0026] During use, the check valve 18 helps prevent air backflow. After the vacuum pump 5 is turned on, the sludge tank 1 becomes under negative pressure and is sealed by the check valve 18. This not only ensures that the negative pressure state can be quickly formed and maintained inside the sludge tank 1, but also avoids pressure fluctuations and pollution problems in the sludge tank 1 caused by air backflow.

[0027] like Figures 1-4As shown, a fixing hole 19 is provided on the top surface of the sludge tank 1, and a pressure sensor 20 is fixed inside the fixing hole 19. Two threaded grooves 21 are provided on the top surface of the sludge tank 1, and two threaded holes 22 are provided on the top surface of the mounting plate 9. Bolts 23 are respectively threadedly connected in the two threaded holes 22, and the threaded ends of the two bolts 23 are respectively threadedly connected to the inner threads of the two threaded grooves 21.

[0028] During use, the pressure sensor 20 facilitates monitoring of pressure changes within the sludge tank 1, ensuring that the equipment operates within a safe range and preventing equipment failure or safety hazards caused by abnormal pressure. The bolts 23 facilitate the disassembly and assembly of the mounting plate 9, thereby facilitating the disassembly and assembly of the filter grille 8 and the vibration motor 10, thereby improving the ease of disassembly and assembly of the filter grille 8 and the vibration motor 10 and reducing maintenance costs.

[0029] like Figure 1-Figure 3 As shown, a sealing ring 24 is fixed to the bottom surface of the mounting plate 9, and the thickness of the sealing ring 24 is 2.5 cm.

[0030] During use, the sealing ring 24 fits tightly against the contact surface between the mounting plate 9 and the sludge tank 1, effectively preventing leakage of sewage and sludge and ensuring the hygiene and safety of the sludge treatment process. Setting the thickness of the sealing ring 24 to 2.5 cm ensures sufficient elasticity and sealing performance, improving not only the fit between the sealing ring 24 and the contact surface but also its ability to withstand pressure and resist wear.

[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
