Embodiment
Below in conjunction with implementing illustration, the present invention is more specifically described:
Referring to Fig. 1 and Fig. 2, this device comprises grill unit, slagging-off unit, sand setting unit and desanding unit.
Grill unit is arranged at the top of device, comprises frame trough 1, coarse rack 2 and fine fack 3.It is two-layer that coarse rack 2 and fine fack 3 are divided into the up and down, is contained in frame trough 1, and frame trough 1 top taps into water pipe, and frame trough 1 bottom is communicated with the sand setting unit; Fine fack slightly all is welded on a plate, and the lower end of plate is connected with rotation axis 15, sees Fig. 5, shakes and rotates when taking out, and thickness grid and plate can overturn 180 °.
Referring to Fig. 3, the sand setting unit has cylindrical shell, dividing plate 4, water outlet 6, effluent trough 7, manhole 10, visor 11, wash water valve 12, water inlet deceleration groove 17 and cover plate 20.Dividing plate 4 is arranged on the cylindrical shell middle and upper part, it is made of a vertical plate and two swash plates, vertical plate vertically is separated into two portions space, left and right to the cylindrical shell middle and upper part, two swash plate symmetries are connected to the both sides, bottom of vertical plate, swash plate both sides and cylinder inboard wall welding, base and cylinder inboard wall have the current gaps, and water must just can flow through the opposite side of cylindrical shell through the current gap on swash plate base like this.
Referring to Fig. 4, the position on the upper baffle plate 4 of cylindrical shell arranges water inlet deceleration groove 17 along cylinder inboard wall, and the groove depth of water inlet deceleration groove 17 strengthens to exit end gradually from entrance end, and main like this is to extend the time of flow, is convenient to sediment settlement.Entrance end is communicated with frame trough 1 bottom, and the left half space that the logical cylindrical shell of exit end middle and upper part is separated out by vertical plate, right half space be logical overflow groove 7, and overflow groove picks out the mouth of a river 6; The end of described cylindrical shell is downward tapered bottom, and sewage draining exit and wash water valve 12 are arranged at the bottom, forms the desanding unit.
Be provided with manhole 10 on the wall at cylindrical shell middle part, be provided with visor 11 on the wall of bottom.The purpose that manhole is set is to be convenient to cleaning equipment inside, when the equipment life-time service, possible some mud attached sacrifices consisting of an ox, a sheep and a pig reality, be difficult to remove from wash water valve, at this time can clean up mud from manhole access arrangement inside by manual type.
The slagging-off unit is arranged on the side of grill unit, comprises slag chute 13, bottom activity slagging plate 14 and side activity slagging plate 18; Described slag chute 13 communicates on top with frame trough 1, when the slag on the thickness grid is more, directly be turned to slag chute after 180 ° of grid upsets, just can unload the slag thing (when some fiber-like slag thing remains on grid from activity slagging plate 18, need activity slagging plate from the side artificial to unloading, therefore be provided with side activity slagging plate), then take out out bottom activity slagging plate 14 the slag thing is removed.
Below the working process explanation of this device:
Fs: the rotary grid of sewage through the equipment top filters the laggard aqua storage tank that enters grid equipment, again after the drainage pipeline of grid device bottom enters sand setting equipment, be subject to immediately slowing down into stopping of water deceleration groove, flow into the storage sand launder of bottom, sluggish flow overflow after deceleration is overflowed to the overflow groove of sand setting equipment.
Subordinate phase: the impurity that in sewage, granularity is larger is cumulative in rotary grid top, grid equipment top, and the fine sand that in the sand launder of sand setting device bottom storage simultaneously, granularity is less is also cumulative.
Phase III: when rotary grid top granularity larger impurities accumulation in grid equipment top arrives some amount, close the sewage water inlet pipe road, rotary grid is upwards overturn 180 ° to level attitude, the slag thing is moved in slag chute, the activity slagging plate of opening grid equipment one side bleeds off slag (referring to bottom activity slagging plate 14 and side activity slagging plate 18), then grid is turned to original position.
Quadravalence section: when the silt in sand setting equipment sand launder runs up to certain quantity, close the sewage water inlet pipe road, open the wash water valve of sand setting device bottom, after impurity and silt are cleaned out, close wash water valve, open the sewage water inlet pipe road, whole plant works on.
