Anti-blocking device for railway vehicle excrement collector

Abstract

The invention provides an anti-blocking device for a railway vehicle excrement collector, and belongs to the technical field of vacuum excrement collectors. An excrement pipe hole is formed in the lower plane of the step along the center line of the front portion of a bottom plate, a vacuum pipe hole is formed in the 45-DEG direction of a second quadrant with the excrement pipe hole as the center,a water tank is arranged on the upper plane of the step on the rear portion of the bottom plate, and a high-pressure air pump is located in a high-pressure air pump box on the right side of the watertank; the water outlet of a flushing supercharger is connected with a vacuum toilet stool through a first water pipe, the tail ends of two vacuum generation devices are connected with silencers and arranged on the upper plane of a horizontal protruding structure side by side, the front ends of the vacuum generation devices are connected with the inlet of an electromagnetic valve through first vacuum pipes, the outlet of the electromagnetic valve is connected with an excrement collecting box through a second vacuum pipe, and the electromagnetic valve is provided with a switch base; an air inlet pipe hole is formed in the upper portion of the excrement discharge pipe of the vacuum toilet stool, and the high-pressure air pump is connected with the air inlet pipe hole through a breather pipe;and a control box is arranged on the back of the vacuum toilet stool. The device is used for preventing the rail vehicle vacuum excrement collector from being blocked.

Description

technical field [0001] The invention belongs to the technical field of vacuum toilets, in particular to an anti-clogging device for a rail vehicle vacuum toilet. Background technique [0002] In recent years, my country's rail transit has made great progress, and the requirements for passenger comfort and environmental protection have become higher and higher. While the speed and safety have been improved, the requirements for passenger ride experience in train operation have also been increasingly recognized by people in the industry. Highly concerned, especially the toilet collection device of the train. According to statistics, in 1416, the cumulative passenger volume of the national railways was about 280 million. Each passenger used the toilet once, excrement was 0.5kg, and the whole road was about 1.4 million tons a year. Causes a lot of pollution, and the vacuum toilet will collect excrement and reduce environmental pollution. [0003] The vacuum toilet is mainly com...
