[0002] Sewage suction trucks are new sanitation vehicles that collect, transfer, clean and transport sludge and sewage to avoid secondary pollution. They are self-priming and self-draining, with fast working speeds, large capacity, and convenient transportation. They are suitable for collecting and transporting liquid substances such as feces, mud, and crude oil. Sewage suction trucks use the domestically advanced vacuum pumps with strong suction power and long suction range, making them particularly suitable for sucking, loading, and unloading sediment in sewers, especially larger objects such as mud, silt, stones, and bricks. The sewage in the truck must be discharged through the sewage discharge device before the next suction operation can begin.

[0003] However, the current sewage discharge device still has some shortcomings. For example, when the sewage is discharged by the existing sewage suction tank, impurities in the sewage are easily adhered to the inner wall of the sewage suction tank, resulting in residual impurities, that is, incomplete sewage discharge, and certain usage defects.

[0004] Therefore, it is urgent to improve this shortcoming. The utility model is to study and improve the existing structural deficiencies, and provide a sewage discharge device and a sewage suction vehicle. Utility Model Content

[0007] Furthermore, six flushing pipes are arranged in a circular distribution around the center point of the cleaning disk, and the cleaning disk and the interior of the conveying pipe are communicated.

[0008] Furthermore, a base is provided at the bottom of the sewage suction tank, and a vehicle body is provided at the lower end of the base, and a hydraulic cylinder three is provided on the left side of the sewage suction tank.

[0009] Furthermore, a sewage suction pump is installed on the surface of the top side of the sewage suction tank, and a sewage suction pipe is installed on the outer end of the sewage suction pump.

[0010] Furthermore, the interior of the suction tank is provided with an auxiliary component for assisting scraping and cleaning, and the auxiliary component includes a partition plate, a scraper bar and a hydraulic cylinder 2. The scraper bar is installed on the outer surface of the partition plate, and the hydraulic cylinder 2 is installed on the left side of the partition plate.

[0011] Furthermore, the partition plate is in the shape of a circular ring, and the partition plate and the scraper are an integrated structure.

[0012] Furthermore, an adjustment hole is provided in the middle of the partition plate, and the partition plate and the adjustment hole are an integrated structure.

[0021] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0022] like Figure 1 and Figure 2 As shown, a sewage discharge device and a sewage suction vehicle include a sewage suction tank 1 and a tank cleaning component 8. A sewage discharge valve 6 is provided at the right end of the sewage suction tank 1, and a hydraulic cylinder 7 is installed inside the sewage suction tank 1. The hydraulic cylinder 7 telescopically controls the sealing disk 802 to move away from the side of the adjusting hole 10. A base 3 is provided at the bottom of the sewage suction tank 1, and a vehicle body 2 is provided at the lower end of the base 3. A hydraulic cylinder 3 11 is provided on the left side of the sewage suction tank 1, wherein when the hydraulic oil in the hydraulic cylinder 3 11 generates pressure under the action of the hydraulic pump, the hydraulic oil will flow into the hydraulic cylinder or hydraulic motor along the pipeline to push the piston or blade to move. In this process, the hydraulic energy is converted into mechanical energy, so that the sewage suction tank 1 rotates with the rotation of the connection between the right end and the base 3 as the base point. At this time, the sewage suction tank 1 can tend to a tilted state, which promotes sewage discharge while preventing sewage from entering the adjusting hole 10. A sewage suction pump 4 is installed on the surface of the top side of the sewage suction tank 1, and the sewage suction pump 4 A suction pipe 5 is installed at the outer end of the pump 4, and an auxiliary component 9 for assisting scraping and cleaning is provided inside the suction tank 1, and the auxiliary component 9 includes a partition plate 901, a scraper 902 and a hydraulic cylinder 2 903. The outer surface of the partition plate 901 is installed with a scraper 902. While the partition plate 901 serves as a space separator in the suction tank 1, the hydraulic cylinder 2 903 controls the movement of the partition plate 901 by telescoping, and a hydraulic cylinder 2 903 is installed on the left side of the partition plate 901. The hydraulic cylinder 2 903 is always slower than the extension speed of the hydraulic cylinder 1 7, so that the scraper 902 scrapes and cleans the inner wall of the suction tank 1, avoids the residue of stubborn impurities and promotes the discharge of liquid from the inner wall of the tank body. The partition plate 901 is in the shape of a circular ring, and the partition plate 901 and the scraper 902 are an integrated structure. An adjustment hole 10 is opened in the middle of the partition plate 901, and the partition plate 901 and the adjustment hole 10 are an integrated structure.

[0023] like Figure 2 and Figure 3As shown, the tank cleaning assembly 8 for cleaning the inner wall of the tank is arranged at the output end of the hydraulic cylinder 7. The hydraulic cylinder 7 gradually extends so that the flushing pipe 804 flushes the inner wall of the suction tank 1 in turn to avoid the existence of dead corners. The tank cleaning assembly 8 includes a connecting block 801, a blocking disk 802, a cleaning disk 803, a flushing pipe 804 and a delivery pipe 805. The end of the connecting block 801 is connected to the blocking disk 802. The connecting block 801 and the cleaning disk 803 are driven by the hydraulic cylinder 7 to extend out of the adjustment hole 10, and the connection A cleaning disc 803 is installed on the outside of the block 801, and a flushing pipe 804 is installed on the right surface of the cleaning disc 803. The annularly distributed flushing pipe 804 flushes out high-pressure water flow to synchronously clean the inner wall of the suction tank 1 to prevent impurities in the sewage from remaining on the tank wall. As the sewage in the suction tank 1 is discharged from the drain valve 6, a delivery pipe 805 is installed on the left surface of the cleaning disc 803. Six flushing pipes 804 are arranged in an annular distribution about the center point of the cleaning disc 803, and the cleaning disc 803 and the delivery pipe 805 are internally communicated.

[0024] A sewage suction truck is equipped with the above-mentioned sewage discharge device. Through the tank cleaning component 8, the sewage suction tank 1 is discharged through the sewage discharge valve 6 to simultaneously flush the inner wall of the tank, so as to prevent impurities in the sewage from adhering to the inner wall of the tank and being unable to be discharged. The auxiliary component 9 assists the tank cleaning component 8 in cleaning the tank wall, that is, scraping off stubborn impurities and promoting the discharge of water stains inside the tank.

[0025] In summary, the sewage discharge device and the sewage suction truck are first based on Figures 1 to 3 In the structure shown in FIG, when discharging sewage, the staff opens the sewage valve 6 to discharge the sewage inside the sewage suction tank 1. When discharging sewage, the base 3 controls the tilt of the sewage suction tank 1 through hydraulic drive, promoting the sewage to approach the sewage valve 6 to promote sewage discharge. When the highest level of sewage does not contact the partition plate 901, the staff controls the hydraulic cylinder 1-7 to extend so that the blocking plate 802 moves away from the side of the adjustment hole 10, controls the connecting block 801 and the cleaning plate 803 to extend out of the adjustment hole 10, and then opens the annularly distributed flushing pipe 804 to flush out the high-pressure water flow to the The inner wall of the sewage suction tank 1 is cleaned synchronously to prevent impurities in the sewage from remaining on the tank wall. As the sewage in the sewage suction tank 1 is discharged from the sewage discharge valve 6, the hydraulic cylinder 1 7 gradually extends so that the flushing pipe 804 flushes the inner wall of the sewage suction tank 1 in turn to avoid the existence of dead corners. At the same time, the hydraulic cylinder 2 903 controls the movement of the partition plate 901 through telescopic control. The hydraulic cylinder 2 903 is always slower than the extension speed of the hydraulic cylinder 1 7, so that the scraper 902 scrapes and cleans the inner wall of the sewage suction tank 1 to avoid the residue of stubborn impurities and promote the discharge of liquid from the inner wall of the tank.
