Further, being horizontally disposed on the lower section inner wall of the liquid seal trough has annular conduit, on the annular conduit Evenly distributed to be equipped with several nozzles, the nozzle is to the liquid seal trough bottom angled；Connect in the water inlet of the annular conduit Logical to be provided with high-pressure hydraulic pump, the water inlet of the high-pressure hydraulic pump is connected with water source by pipeline, the high-pressure hydraulic pump and the control Device processed electrically connects.

The advantages of the utility model：Above-mentioned fluid-tight system structure is simple, easily realize, controller timing controlled high-pressure hydraulic pump and Pump startup is cycled, liquid seal trough bottom is rinsed and by the solid matters such as the filtrate of fluid-tight trench bottom and red mud pump to filtrate receiver, has Preventing the deposition of the solid matters such as red mud, blocking liquid sealing pipe for effect, ensure that liquid sealing pipe is unobstructed, improves the filtering of red mud rotary drum The production capacity of machine, while liquid seal trough is cleared up without stopping production, it ensure that the normal operation of equipment.

Description of the drawings：

Fig. 1 is the overall structure diagram of the utility model embodiment.

Fig. 2 uses schematic diagram for the utility model.

Filtrate receiver 1, liquid seal trough 2, discharge outlet 21, liquid sealing pipe 3, circulating pump 4, water level detector 5, controller 6, annular conduit 7, nozzle 8, high-pressure hydraulic pump 9, water source 10, underflow pump 11.

Specific embodiment：

Below in conjunction with attached drawing, by embodiment, the utility model is described in further detail.

As shown in Figure 1, a kind of new fluid-tight system, including filtrate receiver 1, liquid seal trough 2, liquid sealing pipe 3, circulating pump 4, water level Detector 5 and controller 6；Liquid seal trough 2 is fixed on 1 inner wall of filtrate receiver, the top of liquid seal trough 2 is less than the top of filtrate receiver 1, Liquid sealing pipe 3 is inserted in liquid seal trough 2, the liquid outlet of liquid sealing pipe 3 is located at the bottom of liquid seal trough 2, in the sidewall bottom of liquid seal trough 2 Discharge outlet 21 is offered, discharge outlet 21 is connected with the water inlet of circulating pump 4 by pipeline, water outlet and the filtrate receiver 1 of circulating pump 4 Water inlet connected by pipeline；Water level detector 5 is provided with above 2 inner wall of liquid seal trough, for detecting the water in liquid seal trough 2 Position；Circulating pump 4 and water level detector 5 are electrically connected respectively with controller 6.

Being horizontally disposed on the lower section inner wall of liquid seal trough 2 has annular conduit 7, if evenly distributed on annular conduit 7 be equipped with A dry nozzle 8, nozzle 8 is to 2 bottom angled of liquid seal trough；High-pressure hydraulic pump 9, high pressure are provided with and communicated in the water inlet of annular conduit 7 The water inlet of water pump 9 is connected with water source 10 by pipeline, and high-pressure hydraulic pump 9 is electrically connected with controller 6.
