Embodiment 1

[0035] Such as figure 1 and figure 2 As shown, in the present embodiment, a gravity sewage discharge mechanism of a feces collection system for trains is provided, comprising a transfer box 1 and a dirt box 2, the transfer box 1 is placed above the dirt box 2, and the bottom plate 1a of the transfer box 1 is in contact with the dirt box 2. The top plate 2a of the material box 2 is connected through the communication port 3, and the valve 4 for controlling the connection of the communication port 3 is installed at the communication port 3, and the dirt and waste water entering the transfer box 1 are discharged to the lower part by gravity. In the dirt box 2.

[0036] The communication port 3 is formed by docking the opening on the bottom plate 1a of the transfer box 1 and the opening on the top plate 2a of the dirt tank 2, and the transfer box 1 and the dirt tank 2 are fastened by flanges at the corresponding openings. The devices are fixedly connected together, which is con...

Embodiment 2

[0052] Such as image 3 As shown, the top plate 1b of the revolving box 1 is a flat plate structure, and the top plate 1b can be one of circular, square, semicircular, elliptical, fan-shaped, image 3 The top plate 1b shown in the figure adopts a semicircular structure, and the difference from the first embodiment is that in this embodiment, there is a downwardly recessed part on the top plate 1b, and the setting position of the recessed part 10 is not limited, as long as It only needs to be arranged facing the communicating port 3 , and the driving mechanism 5 is installed on the top plate 1 b in the recessed portion 10 . Setting the recessed part 10 on the top plate 1b is beneficial to further reduce the installation height of the driving mechanism 5 on the premise of ensuring the capacity of the transfer box 1 , and it is also beneficial to shorten the stroke of the valve plug 6 .

[0053] The bottom plate 1a of the transfer box 1 is also a conical structure protruding dow...

Embodiment 3

[0055] Such as Figure 4 and Figure 5 As shown, the difference from Embodiment 1 or Embodiment 2 is that in this embodiment, a second opening 11 is provided on the top plate 1b of the transfer box 1, and a closed valve plug cavity is provided above the second opening 11. 12. The valve plug 6 protrudes into the interior of the transfer box 1 when it is in the blocked state, and moves upward to be accommodated in the valve plug cavity 12 when it is in the open state. The driving mechanism 5 is fixed on the housing of the valve plug chamber 12, the valve plug chamber 12 is fixedly connected with the top plate 1b of the transfer box 1 through the second sealing and fixing structure, the second sealing and fixing structure is an annular fixing seat 13, and the fixing seat 13 and the A sealing ring is arranged between the top plates 1b to realize a sealed connection.

[0056] In this structure, the diameter of the second opening 11 matches the diameter of the valve plug 6, and th...

Abstract

The invention relates to a gravity sewage discharging mechanism of a train excrement collecting system and a vacuum excrement collecting system. The gravity sewage discharging mechanism comprises a transfer box and a dirt box, the transfer box is arranged above the dirt box, the transfer box communicates with the dirt box through a communication port, a valve used for controlling on-off of the communication port is installed at the communication port, the valve is a plug valve or a diaphragm valve, and the transfer box discharges dirt into the dirt box through gravity. The integral structure is simple, the caliber of the communication port is not limited, the plug valve or the diaphragm valve is used for replacing a sliding plate valve in the prior art, gravity pollution discharge can be more stable and reliable, and the maintenance cost can be reduced.

Description

technical field [0001] The invention relates to a vacuum feces collection system for trains, in particular to a gravity sewage discharge mechanism of the feces collection system for trains, and belongs to the technical field of railway vehicle manufacturing. Background technique [0002] In recent years, domestic high-speed trains and other vehicles have all been equipped with vacuum toilet collection systems to collect toilet waste and toilet waste water. Among them, the vacuum toilet collection system with the largest equipment volume is the transit vacuum toilet collection system. The transit vacuum toilet collection system has the characteristics of low energy consumption and short waiting time for multiple toilets. Similarly, the transit vacuum feces collection system also has the disadvantages of too many control components, many failure points, and low cost performance of the system. At the same time, because the transfer vacuum defecation collection systems in the p...
