Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that this place
The specific embodiment described, only in order to explain this utility model, is not used to limit this utility model.
Such as Fig. 1, the dredging tube 20 of rectangle second pond of the present utility model is embedded in below at the bottom of concrete sump pond and its upper surface
Equal with concrete sump baseplane, described dredging tube upper surface is provided with multiple mud-suction hole 25, described dredging tube two ends
Closing and be formed with mudhole 24 in upper surface one end, the area of section of described dredging tube is by spoil disposal nose end to the other end progressively
Reduce.
Dredging tube of the present utility model is embedded at the bottom of concrete sump in advance, with plane and the pond of concrete second pond of mud-suction hole
The end, is equal, and dredging tube is internal smooth, and dredging tube cross section draws near relative to mudhole and becomes larger, it is ensured that each section flow velocity phase
When, by the various sizes of mud-suction hole of upper surface, the mud of precipitation at the bottom of pond is extracted out outside pond uniformly, makes pool bottom sludge thickness
Spend uniform and stable, reach the effect that returned sludge concentration is optimal simultaneously.Simultaneously facilitating installation, civil engineering costs saves.
Specifically, described dredging tube includes base plate 21, fixes the biside plate 22 being connected with described base plate, covers
Two described side plate tops also constitute the cover plate 23 of upper surface, described biside plate is contour and spacing from spoil disposal nose end to another
End progressively reduces.Described biside plate includes cant board and is formed at the connection limit outside cant board top and bottom, described
Base plate and side plate and side plate and cover plate rely on bolt to connect respectively.Dredging tube mode with bolts, interior walls be smooth, cuts
Surface current speed is controlled, simple installation, simple in construction, and framework is convenient, reduces construction cost.
As depicted in figs. 1 and 2, the invention also discloses the mud sucking-exhausting device of a kind of rectangle second pond, it includes
It is arranged on the dredging tube bottom described second pond, and the spoil disposal telescoping valve being arranged in mud canal, described turnbarrel
Valve includes being fixed the inner sleeve 1 being connected by the mudhole of bottom adpting flange with described dredging tube, is rotatably set in
Outer sleeve 2 outside inner sleeve, described inner sleeve and the corresponding position of outer sleeve are offered respectively and are equipped with interior mud discharging mouth 3 and outer spoil disposal
Mouth 4, can realize emission flow by the degree of overlapping of hinged interior mud discharging mouth and outer mud discharging mouth.
The relative motion of outer sleeve and inner sleeve is changed into rotary, by mud discharging mouth and the weight of outer mud discharging mouth in changing
Folded degree realizes Flow-rate adjustment, and i.e. when outer sleeve is relative to inner sleeve different rotation angle, the perforate of outer sleeve can in various degree
On block inner sleeve perforated area, thus the fluid flow that regulation is by this perforate, facility simple to operate.
Preferably, described interior mud discharging mouth be shaped as rectangle, described outer mud discharging mouth be shaped as right-angled trapezium, institute
The top margin of the right-angled trapezium stated and base all with the axially vertical setting of outer sleeve.By adjusting different openings shape inner-outer sleeve
Relative angle, changes area of passage, adjusts flow the finest.
Further, for ease of force, also include fixing, with described outer sleeve top, the adjusting rod 5 being connected.And, just

Outer sleeve top be provided with instruction unit, such as instruction pin or indicator board, described indicator board is formed and described instruction
The mark part that portion is corresponding, it is preferable that described instruction unit is 5 aperture instructions.Specifically, indicator board has at 5 and open
Groove indicates as aperture, corresponding 5 different angles, respectively corresponding the 0% of the inner sleeve area that blocks, and 25%, 50%, 75%,
100%, and labelling X respectively on indicator board, 3/4,1/2,1/4,0, thus reach to regulate fast and accurately the purpose of flow.
Described instruction unit is to fix the spacer being connected with described outer sleeve, and described mark part is described for being formed at
Through hole ring week can be matchingly by the described clamped groove therein of spacer.
Wherein, the top of inner sleeve and outer sleeve is not closed, and mud position is highly below inner sleeve and outer sleeve
Top is so that normal spoil disposal, and by the mud discharging mouth spoil disposal of sidepiece, need not seal between inner sleeve and outer sleeve, simplifies knot
Structure reduces cost, improves stability.
Specifically, outer sleeve outer wall is provided with the radially prominent spacer 7 extended, indicator board has 5
Place's groove 8 is as mark part, and both are in sustained height scope, when needs adjust angle, is first slightly mentioned by outer sleeve, makes
Banking stop leaves groove scope, after rotating to need angle, and the putting down again and again of position at the most above-mentioned 5, make banking stop insert groove,
Preventing outer sleeve from rotating freely, outer sleeve does not upwards have spacing, is placed in the adpting flange of inner sleeve after being adjusted in place by its deadweight
On, terminal with compact integral structure operation is convenient, and stability is high, and service life is long.
Telescoping valve of the present utility model is suitable for and is installed on Zhou Jinzhou and goes out the dredging tube of chain mud scraper and combine, reach and
Time, uniformly, effectively pool bottom sludge is discharged, regulate the purpose of sludge back flow quantity accurately, it is ensured that returned sludge concentration and setting
Standby and process the properly functioning of technique, dredging tube makes variable cross-section rectangular duct form, has simple in construction, easy for installation, soil
The advantage building easy cost saving of constructing.Rotary adjustable-flow spoil disposal telescoping valve overcomes former hoisting type telescoping valve regulating time
Long and flow is difficult to accurately control, and has spoil disposal canal civil engineering amount simultaneously and reduces, the advantage that corresponding investment cost reduces.
The above is only preferred implementation of the present utility model, it is noted that general for the art
For logical technical staff, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these change
Enter and retouch and also should be regarded as protection domain of the present utility model.
