Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of feces suction vehicles, in particular to a negative pressure vacuum feces suction vehicle. Background Art
[0002] Fecal suction trucks are mainly used as special vehicles for cleaning work in environments such as septic tanks, sewage ditches and sewers. Together with sprinkler trucks and garbage trucks, they are known as the three major sanitation vehicle types. They are mainly used for sucking and transporting feces and other sewage for urban and rural sanitation departments. With the advancement of technology, vacuum fecal suction trucks have begun to be used. Their high-pressure automated sewage treatment method can dehydrate the pumped-up sewage, achieve solid-liquid separation, and improve the sewage treatment effect.
[0003] When the fecal suction truck is sucking the waste liquid in the underground sewer, some odor is easy to overflow from the sewer outlet. The traditional fecal suction truck needs to carry special air purification equipment or sealing shielding objects for blocking. Not only is the cost high, but the sealing effect is poor, which still brings many inconveniences to the people around. Moreover, when sealing with external sealing shielding objects, due to the large force easily generated during suction, the pipe fittings are easy to carry the movement of the sealing shielding objects, which requires manual support and stability, and the overall use effect is poor.
[0004] To this end, we propose a negative pressure vacuum fecal suction truck to solve the above problems. Utility Model Content

The ventilation box 8 and the compressed air bag kit 5 are both slidably sleeved on the outside of the liquid guide tube head 9, and the ventilation box 8 and the compressed air bag kit 5 are connected through the air guide connecting pipe 13. An adsorption hole 21 is opened at the bottom of the compressed air bag kit 5. The adsorption hole 21 is mainly to facilitate the adsorption and air guide of the compressed air bag kit 5. The use of the above-mentioned components, the ventilation box 8, the compressed air bag kit 5 and the sealing extrusion rubber ring 10 at the bottom are covered at the sewer opening to form a sealed space. When the fecal suction truck is in suction operation, the vibration generated causes the compressed air bag kit 5 to be continuously compressed, so that the gas is introduced into the ventilation box 8 and is discharged after being filtered by the purification adsorption active layer 12 for odor. This not only saves costs, but also improves the sealing performance and prevents the direct overflow of odor from affecting the outside.

[0038] Specifically, a filter separation layer 15 is installed in the middle of the interior of the vacuum tank body 2. The filter separation layer 15 mainly serves to separate water and feces. The upper and lower layers of the interior of the vacuum tank body 2 are divided into a liquid accumulation layer 18 and a residue storage layer 17 through the filter separation layer 15. The bottom end of the liquid guide pipe head 9 is threadedly sleeved with a liquid extraction pipe 6. The liquid extraction pipe 6 can be easily disassembled and directly extended to the bottom of the sewer for feces water suction operations. The top of the liquid guide pipe head 9 is located inside the residue storage layer 17 and is connected to a liquid guide head 16.
