Vacuum toilet wastewater collector

Abstract

The invention discloses a vacuum toilet wastewater collector comprising a squatting pan, a vacuum tank, a dirt cache box, a sewage pump, a vacuum pump, a PLC controller, a vacuum switch, a self-priming pump, a flush water temporary storage tank, an air temporary storage tank and an air compressor. The squatting pan is connected with the dirt cache box which is connected with the vacuum tank. The vacuum tank is connected with the vacuum pump. The sewage pump is installed in the dirt cache box. The self-priming pump is connected with the squatting pan. The vacuum switch is arranged between the squatting pan and the dirt cache box. An air and water isolating valve is arranged between the air temporary storage tank and the flush water temporary storage tank. A flush water electromagnetic valve is arranged between the flush water temporary storage tank and the squatting pan. The flush water temporary storage tank is connected with the external part via a pressure release electromagnetic valve. The PLC controller is respectively connected with the air and water isolating valve, the flush water electromagnetic valve, the pressure release electromagnetic valve and a vacuum air valve. The sewage pump in the dirt cache box has cutting and smashing effects so that pipeline blocking can be effectively reduced. The vacuum tank is arranged so that vacuum establishing time is saved and noise is reduced in comparison with existing vacuum toilet wastewater collectors.

Description

technical field [0001] The invention relates to the technical field of toilets, in particular to a vacuum toilets collection device. Background technique [0002] The toilet is an important facility in the toilet, widely used in locomotives, airplanes, public places, etc. In particular, the vacuum toilet collection device is simple to operate, convenient to use, and saves water sources, and is hygienic and environmentally friendly. [0003] Common vacuum closets generally adopt vacuum holding type, online type or push-pull type etc. at present. The vacuum holding type dirt tank keeps vacuum all the time, and the compressed air consumption is large and the noise is louder every time the vacuum is established; the online pipeline requires a fast speed for each vacuum establishment, so the compressed air flow is required to be large and the noise is relatively large; the general push-pull type Positive pressure and negative pressure are required to control the discharge of po...
