Not only is the bottom of the grit chamber zone designed to have a two-stage V-shaped structure with certain inclination so as to effectively collect the grit, but also a floating object collecting tank is arranged at the front part of the grit chamber zone so as to effectively collect floating objects through the inclination design of a baffle.
Description
Technical field
The utility model relates to the process field of flushing water in the refuse moisture choosing processing, the setting pot that flushing water was handled during particularly a kind of refuse moisture choosing was handled.
Technical background
In the domestic rubbish disposal process, handle for the flushing water that satisfies after refuse moisture choosing is handled, generally all comprise a setting pot, the setting pot of often using both at home and abroad has four kinds at present: flat flow, vertical-flow, aeration type and cyclone-type sand precipitating pool.
Wherein, traditional rectangular sedimentation tank is simple in structure, and desanding effect is good, and the production domesticization degree height of desanding device, be the main pond type of the setting pot of China municipal sewage plant, but sand setting being carried 15% organic matter secretly in the horizontal-flow grit chamber, is that sand setting subsequent treatment difficulty increases.
Wherein, the vertical sedimentation basin desanding effect is poor, and operational management inconvenience is at home and abroad seldom used.
Wherein, the aeration type sedimentation basin is on the basis of rectangular sedimentation tank, increases air diffuser at side wall, makes sewage produce lateral flow, forms spiral rotation status.The desanding efficiency height, the good separating effect of organic matter and sand, but its maintenance and transformation are relatively more difficult.
Wherein, spiral-flow type sedimentation basin floor space is little, the desanding efficiency height, but this pond type and desanding device are foreign patent, and its key equipment is external product, and cost of investment is bigger.
Summary of the invention
In order to overcome above technological deficiency, when providing one effectively to collect sandstone, effectively collects the utility model the high efficiency setting pot of floating thing.
To achieve these goals, the utility model provides a kind of high efficiency setting pot, it is characterized in that: comprise the setting pot district, described setting pot district is set to have the two-stage V-structure of constant slope, comprise first order slope and slope, the second level, described first slope is arranged at the flow inlet place makes sectional area become big, and slope, the second level is arranged at the end on first slope, and sandstone is flowed in the sand pit of collecting sandstone along described second slope.
Wherein, preferred version is: comprise that also a plate washer is arranged at the front end in setting pot district, can height up and down, and do not have 45 ° of angles but do not touch at the bottom of the pond and with respect to the setting pot flow path wall, it is 50mm that baffle plate immerses the underwater portion optimum depth.
Wherein, preferred version is: comprise that also a feeder places the front end in setting pot district, the import of described baffle plate side and described feeder is communicated with, floating thing in the current is collected in the feeder by the baffle plate shunting of described inclination, described feeder has a grid conveyer belt, be installed in the feeder, the floating thing that described grid conveyer belt is collected described feeder transmits.
Advantage of the present utility model is: not only by angled two-stage " V " the shape structure of setting pot district bottom design, effectively collect sandstone, effectively collect floating thing by the inclined design of baffle plate simultaneously.

The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
With reference to figure 1, Fig. 2, Fig. 3 and Fig. 4, a kind of high efficiency setting pot 10 of the utility model comprises setting pot district 11, baffle plate 12, grid conveyer belt 13, described sand setting district 11 is set to have two-stage " V " the type structure of constant slope, the sand setting district 11 of described " V " type structure has first order slope 111 and slope, the second level 112, described first order slope 111 is arranged at the flow inlet place, its best gradient is 3 °, and first order slope 111 front ends are no less than 4.5m apart from the length of sewage inlet, make floating thing have enough distances and time to float on the water surface; It is big that flow inlet road 111 sectional areas in setting pot district 11 become suddenly, and volume is increased, and flow velocity can reduce before sewage flow to sand setting district 11 like this, slowly entered the setting pot district, was beneficial to sand setting; Described second slope 112 is arranged at 114 places, sand pit in sand setting district 11, and its best gradient is 55 °.
The top in described sand pit 114 also is provided with grid conveyer belt (not shown) in order to the bigger silt of collecting granules, and the less silt of particle then is evacuated in the grit water separator by pump and dewaters.
Before described baffle plate 12 is arranged at setting pot district 11, but height up and down, but do not touch the bottom, it is 50mm that described baffle plate 12 immerses the underwater portion optimum depth, and described baffle plate 12 has 45 ° of angles with respect to the pool wall 113 in setting pot district 11, the floating thing that described 45 ° angle is beneficial in the current is collected in the feeder 121 by the baffle plate 12 of described inclination, be provided with grid conveyer belt 13 in the described feeder 121, the floating thing of described feeder 121 being collected by described grid conveyer belt 13 transmits, described feeder 121 is positioned at the front end in setting pot district 11, has certain slope (not shown) the moisture in the feeder 121 is flowed in the sand pit 114 in sand setting district 11.
The utility model sand setting operation principle is: current are via first slope 111, because first slope 111 makes cross section of fluid channel amass sudden enlargement, flow velocity reduces, and the floating thing in the current utilizes current to be collected in the feeder 121 after baffle plate 12 blocks, and the back is collected by grid conveyer belt 13 and transmitted; Current flow in second slope 112 in sand setting district 11 and utilize the proportion difference of various materials, the silt that proportion is bigger, and rapid precipitation flows in the sand pit 114 naturally through spigot at the bottom of the pond.
Design principle of the present utility model is: the flow design of setting pot 10 is to calculate according to maximum stream flow, is 2250m
3/ d, the design Peak Flow Rate is 0.3m/s, and minimum is 0.15m/s, and the time of staying is 40s.Because angled two-stage " V " the shape structure of setting pot bottom design in setting pot district 11, the gradient on first slope 111 is 3 °, 55 ° of the gradients on second slope 112, the length on first slope 111 (flow inlet place to the settling zone 11 distance) should be no less than 4.5m, so that floating thing has time enough to emerge, the floating thing baffle plate 12 that arranges should not be dark excessively, the degree of depth is underwater 50mm, thereby influence the sand setting effect otherwise can influence water flow velocity, between baffle plate and pool wall certain included angle is arranged so that floating thing can enter in the floating thing feeder smoothly.
Advantage of the present utility model is: not only effectively collect floating thing by the inclined design of baffle plate 12, by angled two-stage " V " the shape structure of setting pot district 11 bottom design, effectively collect sandstone simultaneously.
The above person is the utility model most preferred embodiment only, is not for restriction scope of the present utility model, and all equivalences of doing according to the utility model claim change or modify, and are all the utility model and contain.
