Abstract
The utility model provides a shield constructs quick-witted shield tail waste fitting discharging, including soil pick-up pipe, diaphragm pump and sewage case, soil pick-up pipe, diaphragm pump and sewage case communicate in proper order, the intercommunication has a plurality of soil pick-up branch pipes on the soil pick-up pipe, the soil pick-up branch pipe is provided with the soil pick-up mouth. The utility model discloses a set up a plurality of soil pick-up branch pipes that take the soil pick-up mouth on the soil pick-up pipe, enlarged the adsorption sphere of soil pick-up pipe.
Description
Technical Field
The utility model belongs to the shield constructs the machine field, concretely relates to shield constructs quick-witted shield tail waste fitting discharging.
Background
In the shield tunneling construction process, as the flushing pipe sheet can generate sewage, a sewage pump is adopted for pumping and discharging under normal conditions. One is to adopt a common slurry pump which is hung by a chain block, but because the segment of the shield tail is arc-shaped, the slurry pump can not pump and discharge at low liquid level, and the slurry pump can not adopt water cooling, so that the water pump is easy to burn, and the oil cylinder of the shield tail is easy to extrude and damage; the other is to adopt a diaphragm pump, but the sewage suction port of the diaphragm pump is a common round pipe, so that the adsorption range is limited.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model provides a shield tail waste fitting discharging of shield constructs machine to improve the absorption scope of the soil pick-up mouth of diaphragm pump.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a shield constructs quick-witted shield tail waste fitting discharging, includes sewage suction pipe, diaphragm pump and sewage case, sewage suction pipe, diaphragm pump and sewage case communicate in proper order, the intercommunication has a plurality of soil pick-up branch pipes on the sewage suction pipe, the soil pick-up branch pipe is provided with the soil pick-up mouth, the soil pick-up mouth is cylindrical, honeycomb holes are seted up to the bottom of soil pick-up mouth.
Further, be provided with the quick interface that is used for connecting the diaphragm pump on the soil pick-up pipe, be equipped with the stainless steel filter screen in the quick interface.
Compared with the prior art, the beneficial effects of the utility model are that:
the sewage suction pipe is provided with a plurality of sewage suction branch pipes with the sewage suction ports, so that the adsorption range of the sewage suction pipe is expanded.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of a soil suction pipe;
FIG. 3 is a schematic view of the structure of FIG. 2 from another perspective;
in the drawings, the components represented by the respective reference numerals are listed below:
1. sewage suction pipe, 2, diaphragm pump, 3, sewage tank, 4, sewage suction branch pipe, 5, sewage suction port.
Detailed Description
The present invention is further described in detail below with reference to specific embodiments so that those skilled in the art can more clearly understand the present invention.
As shown in fig. 1-3, a shield tail pollution discharge device of a shield machine comprises a sewage suction pipe 1, a diaphragm pump 2 and a sewage tank 3, wherein the sewage suction pipe 1, the diaphragm pump 2 and the sewage tank 3 are sequentially communicated, the sewage suction pipe 1 is communicated with three sewage suction branch pipes 4, and the sewage suction branch pipes 4 are provided with sewage suction ports 5.
The soil pick-up mouth 5 is cylindrical, honeycomb holes are seted up to the bottom of soil pick-up mouth 5, and honeycomb holes can regard as primary filter, filters partly dirt, improves soil pick-up efficiency.
Be provided with the quick interface that is used for connecting diaphragm pump 2 on the soil pick-up pipe 1, be equipped with the stainless steel filter screen in the quick interface, the stainless steel filter screen on the quick interface can be to the sewage filtration that is about to get into the diaphragm pump, the diaphragm life-span of an extension diaphragm pump.
The mechanisms, assemblies and components of the present invention that are not described with respect to specific structures are conventional structures that exist in the prior art. Can be purchased directly from the market.
The above is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
