Abstract
The utility model relates to a gas-injection variable flow siphon for a suction dredge, which comprises an ascending pipe section, a horizontal pipe section and a descending pipe section. The horizontal pipe section or the descending pipe section is provided with at least one upper gas inlet device communicated with the horizontal pipe section or the descending pipe section by the aid of a connecting pipe. The gas-injection variable flow siphon is reliable in operation and simple in structure without linkage components, can be started directly, and is convenient in equipment maintenance so that production cost is reduced greatly. As the gas-injection variable flow siphon does not contact with sludge, the flow velocity of muddy water in the siphon can be changed only by leading in a small amount of gas, easily damaged components are less, and only a few air inlet regulating valves need to be mounted.
Description
Technical field
The utility model relates to a kind of syphon tube, a kind of suction dredger of saying so accurately air injection type unsteady flow amount syphon tube.
Background technique
The deposition tank of water factory all is end water inlet, the other end water outlet, the impurity in this process in the water precipitates gradually, and it is limpid that water becomes, the distribution of the glar at the bottom of the deposition tank is gradually reduced by feed-water end to waterexit end, and glar then needs with suction dredger mud to be excluded at the bottom of the pond.Usually used suction dredger is provided with 6～8 syphon tubes side by side, and as shown in Figure 3, syphon tube 1 is made up of rising pipeline section 2, horizontal pipeline section 3 and decline pipeline section 4, and siphon power is poor from suction head; But existing syphon tube does not all have unsteady flow amount function, and it is constant that suction dredger moves to its suction mud amount of the other end by an end, very rare at the muddy water of the few section sucking-off of mud, has wasted a large amount of semi-finished product tap water.The hydrocone type suction dredger of some import has at present had been noted that this problem, it inhales the mud amount can be divided into two, three class, inhale the class of mud amount in the automatic conversion of several zoness of different of inhaling mud sump 5, its technological scheme all is to set about from the syphon tube outside, promptly install an electric control valve 7 additional at siphonal mud discharging mouth 6, regulate flow according to this, because general suction dredger all has the mud discharging mouth more than six, a mud discharging mouth need be installed a modulating valve, so just need unify to regulate opening and closing with linking mechanism, the structure more complicated, working medium is a muddy water in addition, rate of fault is higher, and its maintenance cost also can rise thereupon.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, provides a kind of suction dredger with air injection type unsteady flow amount syphon tube, requires its valve body parts few, and no linkage part can solve the problem of suction dredger Flow-rate adjustment.
In order to solve above technical problem, the utility model proposes a kind of suction dredger air injection type unsteady flow amount syphon tube, comprise rising pipeline section, horizontal pipeline section and decline pipeline section, be provided with air inlet system at least one at described horizontal pipeline section or decline pipeline section, the described air inlet system of going up communicates with described horizontal pipeline section or decline pipeline section by taking over, allow air enter, change flow rate of fluid in the syphon tube according to hydromechanical principle by air inlet system on this.
The technological scheme that the utility model further limits is:
Aforesaid suction dredger is arranged on described decline pipeline section upper position with air injection type unsteady flow amount syphon tube, the described air inlet system of going up, and keeps air inlet system can be got final product near the metal line of correspondence.
Further, aforesaid suction dredger air injection type unsteady flow amount syphon tube is characterized in that: described upward air inlet system is tightly connected by adapter by distribution tube and a shared suction valve and forms.
Aforesaid suction dredger is with air injection type unsteady flow amount syphon tube, on corresponding described on its described decline pipeline section the bottom of air inlet system be provided with again one with described on the identical following air inlet system of air inlet system structure.
The utility model is the characteristics of negative pressure according to the syphon tube of suction dredger in horizontal pipeline section and decline pipeline section, in horizontal pipeline section of syphon tube or decline pipeline section, inject air, air has occupied the pipe internal volume on the one hand and has directly reduced the muddy water amount, alleviated the muddy water proportion in horizontal pipeline section or the decline pipeline section on the other hand, reduced the power of siphon, thereby reduced suction mud amount, thereby controlled the size of inhaling the mud amount by the amount of injecting air.The method of injecting air is also simple, because the pressure in horizontal pipeline section or the decline pipeline section is negative pressure, as long as open an aperture at horizontal pipeline section or decline pipeline section, air becomes and can enter automatically.
The beneficial effects of the utility model: the utility model reliable operation, no linking mechanism can directly start simple in structurely, does not contact muddy water; This covering device is cheap in addition thinks that valve is few and the suction valve price is low, the latus rectum of valve is little, because do not contact muddy water, as long as feed a spot of air, and tens times of the passable liquid of the flow velocity of air, a described main valve is much smaller than the volume of a siphonal muddy water valve, and effect is very good.

Embodiment
Embodiment 1
It is a kind of that present embodiment provides, structure as shown in Figure 1, comprise rising pipeline section 2, horizontal pipeline section 3 and decline pipeline section 4, be provided with air inlet system at least one at described decline pipeline section 4, described upward air inlet system is tightly connected by upper connecting tube 10 by last distribution tube 8 and a shared upper inlet valve 9 and forms, the described air inlet system of going up communicates with described decline pipeline section 4 by upper connecting tube 10, and the described air inlet system of going up is arranged on described decline pipeline section 4 upper positions, allows air be entered by air inlet system on this.The bottom of air inlet system is provided with a following air inlet system again on correspondence on the described decline pipeline section 4 is described in addition, and air inlet system comprises lower linking tube 11, following distribution tube 12 and lower inlet valve 13 under it.
Working principle of the present utility model: under suction dredger, connect many top sustained heights with siphonal decline pipeline section all be connected with air inlet system, 500～800 ㎜ places are provided with a following air inlet system again below this device; Because residing height is high more on the decline pipeline section, negative pressure value is just big more so, so the air inflow of last air inlet system is just much larger than following air inlet system.So just, obtained the air inflow of four class, i.e. the suction mud amount of four class, that is exactly: air inlet system complete shut-down---strong, following air inlet system is opened---is inferior strong up and down, and last air inlet system is opened---in, air inlet system standard-sized sheet up and down---a little less than.
In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
