Problems solved by technology

According to the principle of atmospheric pressure and the limit value of the vacuum degree that can be realized by the vacuum pump 20, it is generally considered that the limit value of the vacuum degree in the sewage tank 10 is 93%, and then the maximum suction height that can be achieved by the sewage suction pipe 30 during suction is 9.3m, when the position of the suctioned dirt is too low or the actual vacuum degree in the sewage tank 10 is smaller, it is impossible to complete the operation through negative pressure suction
and, if figure 2 As shown, when using a sewage suction truck to s

Abstract

The invention relates to the field of environment sanitation, and discloses suction sewage equipment, a suction sewage truck and a suction sewage method. The suction sewage equipment comprises a sewage tank (10), a vacuum pump (20) for the sewage tank (10), and a suction sewage pipe (30) communicating with the sewage tank (10), wherein a port for controlling the suction sewage pipe (30) and a valve (40) communicating with the sewage tank (10) are arranged on the suction sewage pipe (30). According to the suction sewage equipment disclosed by the invention, the valve is opened when the degree of vacuum in the sewage tank reaches a predetermined value, a large pressure difference is generated at the port of the suction sewage pipe instantly and a strong air flow is formed, so that the sewage is conveyed into the sewage tank by the air flow, and a convey height difference generated in the manner, which is greater than that generated through the negative pressure suction is achieved.

Description

technical field [0001] The invention relates to the field of sanitation, in particular to a sewage suction device, a sewage suction vehicle and a sewage suction method. Background technique [0002] Existing sewage suction vehicles all use negative pressure to suck sewage, specifically, such as figure 1 , The sewage suction truck includes a sewage tank 10, a vacuum pump 20 for the sewage tank 10 (the vacuum pump 20 is connected to the sewage tank 10 through a vacuum tube 70 and discharges the extracted air into the atmosphere through a muffler 80) and a sewage suction tank communicated with the sewage tank 10. Tube 30. During operation, it is necessary to insert the port of the sewage suction pipe 30 under the liquid surface of the liquid sewage L. According to the principle of atmospheric pressure and the limit value of the vacuum degree that can be realized by the vacuum pump 20, it is generally considered that the limit value of the vacuum degree in the sewage tank 10 i...
