Detailed Description
For a further understanding of the invention, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings.
The structure of the present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1 to 3, a settling tank for sewage treatment provided by an embodiment of the present invention includes a tank body 3 having a water inlet 1 and a water outlet 2, and further includes: a settling plate 4 disposed in the box 3 and having an upper layer and a lower layer, and a plurality of receiving areas having a predetermined height are provided between the settling plates 4 (see fig. 3); the sedimentation plate 4 is internally provided with a main channel 5 and a first through hole 6 communicated with the main channel 5, and the first through hole 6 is arranged on the upper surface of the sedimentation plate 4; the main channel 5 is communicated with an openable and closable pipeline 7, and the lower end of the pipeline 7 extends to the outer side of the box body 3.
In this setting, after sewage gets into box 3 from water inlet 1, is separated in a plurality of accommodation area, in each accommodation area, the sediment in the sewage can accomplish the sediment as long as falling to the upper surface of precipitation plate 4, and need not to fall to the diapire of box 3, has consequently shortened the required stroke of sediment, has improved precipitation efficiency. When the sediment impurities on the upper surface of the sediment plate 4 need to be removed, the pipeline 7 is opened, sewage close to the sediment plate 4 flows into the first through hole 6 under the action of gravity, and the sediment impurities on the upper surface of the sediment plate 4 are driven to enter the first through hole 6, then sequentially pass through the main channel 5 and the pipeline 7, finally the box 3 is discharged, and finally the pipeline 7 is closed, so that other sewage is discharged from the water outlet 2 and enters the next treatment procedure. Since the sewage is divided into a plurality of accommodation areas, sediment accumulation in each accommodation area is not excessively high, and thus the discharge of impurities is also facilitated.
Further, as for the settling plates 4, in one embodiment, there may be provided a plurality of settling plates 4, the settling plates 4 being arranged in a single row or a plurality of rows, the settling plates 4 located in the same row being aligned up and down to form a receiving area between the settling plates 4, by which the above object can be achieved.
In another embodiment, referring to fig. 3 and 4, the inner cavity of the box 3 is a cylindrical cavity, the pipe 7 is vertically disposed and coaxially disposed with the inner cavity of the box 3, the shape of the sedimentation plate 4 is spiral, and the sedimentation plate 4 is circumferentially disposed on the pipe 7.
By the arrangement, on one hand, when sewage is injected, the sewage can rotate and move downwards on the sedimentation plate 4, so that the upper surface of the sedimentation plate 4 is cleaned from top to bottom, and each time the sewage is injected, the flushing effect can be realized; on the other hand, this arrangement takes up less horizontal space.
The typical ratio of the pitch to the outer diameter of the precipitation plate 4 is 1:1-2, whereas in the present arrangement the ratio of the pitch and the outer diameter of the sedimentation plate 4 is 1:4-10. When the ratio of pitch to outside diameter is higher than 1:4, at this time, the pitch of the precipitation plate 4 is larger, the inclination of the precipitation plate 4 is larger, and the precipitated impurities on the precipitation plate 4 easily slide down. When the ratio of pitch to outside diameter is below 1:10, at this time, the pitch is too small, so that the height of the accommodation area is small, on the one hand, the time required for precipitation cannot be significantly reduced, and on the other hand, waste is caused in terms of materials, processes and the like of the precipitation plate 4, and in the subsequent setting, the energy consumption for driving the precipitation plate 4 to rotate is increased. The ratio of the pitch to the outer diameter of the precipitation plate 4 is 1:4-10, the height of the receiving area is moderate and the precipitated impurities on the precipitation plate 4 are not easily slipped down.
Further, the edge of the sedimentation plate 4 is attached to the inner wall of the box body 3. If a gap is formed between the sedimentation plate 4 and the inner wall of the box body 3, sediment in the gap can fall to the bottom wall of the box body 3, and the travel is long, so that the sedimentation speed is not improved. Therefore, the adhesion of the edge of the sedimentation plate 4 to the inner wall of the tank 3 can solve this problem. Also, the upper surface of the settling plate 4 may be provided with a matte surface (e.g., a frosted surface) to prevent settled impurities from sliding down.
Referring to fig. 1 and 3, the lower end of the pipe 7 extends out of the tank 3, the lower end of the pipe 7 is connected with an impurity collecting tank 8 through a connecting pipe 71, and the connecting pipe 71 is provided with a valve 9.
Through this setting, can control opening and close of pipeline 7 through opening and close of valve 9, after the sediment is accomplished, open valve 9, can make the box 3 reclaimed water drive the sediment impurity on the sediment board 4 enter into first through-hole 6, then in the main channel 5, pipeline 7 and connecting pipe 71 enter into impurity collecting box 8 in proper order, then close valve 9, can accomplish the discharge of impurity. Preferably, the impurity collection bin 8 has a plurality of bins to accommodate more impurities. In practice, the piping 7 and the connection pipe 71 may be communicated by a pump (e.g., a sludge pump), thereby generating suction to the piping 7 to facilitate the discharge of precipitated impurities.
For example, referring to fig. 3 and 4, the first through holes 6 have a plurality of shapes and are arranged in a strip shape, and the plurality of first through holes 6 are arranged in a circular shape at equal intervals. On the one hand, the precipitated impurities on the upper surface of the precipitation plate 4 slide down into the first through holes 6 and further into the main passage 5 even if they slide down. On the other hand, the cleaning mechanism which is convenient for the subsequent setting dials the precipitated impurities on the precipitation plate 4 into the first through hole 6, thereby facilitating the discharge of the precipitated impurities.
Referring to fig. 4 and 5, the lower surface of the sedimentation plate 4 has a plurality of second through holes 10 communicating with the main channel 5, and the plurality of second through holes 10 are equally spaced.
By this arrangement, in one accommodation area, while the precipitated impurities in the sewage are sinking, the floating impurities in the sewage float up to the lower surface of the upper layer of precipitation plate 4, and when the pipe 7 is opened to discharge the precipitate, the water flow can also drive the floating impurities to enter the main channel 5 through the second through hole 10, and then be discharged through the lower end of the pipe 7. Through this setting, not only can get rid of and deposit impurity, can also get rid of floater impurity. And because the floater impurity only need float in holding the interval, the stroke of floating is less, consequently can improve the speed of getting rid of floater impurity.
When the width dimensions of the first through holes 6 and the second through holes 10 are large (the ratio of the length dimension to the width dimension is less than 10:1), the second through holes 10 and the first through holes 6 are staggered or partially misaligned, so that a large amount of precipitated impurities cannot fall into the next accommodation space through the first through holes 6 and the second through holes 10 in sequence, and a large amount of floating impurities cannot float up into the previous accommodation space through the second through holes 10 and the first through holes 6 in sequence, thereby limiting the movement space of the precipitate and the floating matters to the accommodation area.
Of course, when the width dimensions of the first through hole 6 and the second through hole 10 are smaller (the ratio of the length dimension to the width dimension is more than 10:1), for the convenience of processing the first through hole 6 and the second through hole 10, the first through hole 6 and the second through hole 10 can be aligned, because the width dimensions of the first through hole 6 and the second through hole 10 are smaller, the quantity of impurities passing through is within the process requirement, and the operation cannot be influenced.
Further, a gas supply member and/or a liquid supply member (not shown) is/are connected to the upper portion of the pipe 7.
By this arrangement, first, the flocculant after dissolution can be directly injected into each accommodation area through the pipe 7, improving the injection efficiency of the flocculant. Second, the first through-holes 6 and the second through-holes 10 can be backwashed to prevent clogging. Thirdly, the air can be supplied to the pipeline 7 through the air supply member, so that the air is discharged from the first through hole 6, and the floating speed of the floating objects can be improved (the floating objects are suitable for the situation that the precipitated impurities are discharged). In specific implementation, the air supply piece or the liquid supply piece can be independently arranged, or the air supply piece and the liquid supply piece can be arranged and are communicated with the upper end of the pipeline 7 through the switching valve. The air supply member and the liquid supply member may be set to a high pressure or common liquid pump, or an air pump according to the use requirement of the distance, and will not be described herein.
The outer peripheral surface of the pipe 7 is provided with a third through hole 20, the third through hole 20 is provided with a one-way valve, fluid is allowed to flow into the cavity through the pipe 7, the fluid in the cavity is prevented from flowing into the pipe 7, and the gas supply piece and/or the liquid supply piece can supply and discharge gas and/or liquid into the pipe 7, and when the gas and/or the liquid is sprayed out of the third through hole 20, the upper surface and/or the lower surface of the sedimentation plate 4 can be flushed. In particular embodiments, the third through-hole 20 may be inclined in different directions, thereby increasing the cleaning area.
Referring to fig. 1 and 3, the device further comprises a rotation driving mechanism for driving the pipe 7 to rotate; the rotation driving mechanism comprises a first motor 11, and the output end of the first motor 11 is in transmission connection with a first gear 12; the second gear 13 is fixedly mounted on the outer peripheral surface of the pipe 7, and the first gear 12 is meshed with the second gear 13.
For example, the output end of the first motor 11 is connected with a first gear 12 in a transmission way, and the arrangement is as follows: the output end of the first motor 11 is connected to the first gear 12 through a gearbox. By this arrangement, on the one hand, the conduit 7 and the sedimentation plate 4 can be driven to rotate, and on the other hand, the upper end of the conduit 7 and the air supply member and/or the liquid supply member are not hindered from being connected by the conduit 7.
The advantage of the rotation of the sedimentation plate 4 is that:
first, the edges of the sedimentation plate 4 may be provided with brushes so that the inner wall of the tank 3 may be cleaned when the sedimentation plate 4 rotates. Referring to fig. 4-6, the upper edge of the sedimentation plate 4 is provided with a first impurity discharging channel 14 communicating with the main channel 5, and when the pipe 7 is opened, the sedimentation plate 4 can discharge the sediment impurities accumulated between the inner wall of the box 3 and the edge of the sedimentation plate 4 when rotating one turn. And impurities on the inner wall of the brush can be conveniently removed. Preferably, the first through hole 6: second through hole 10: the volume ratio of the liquid discharged from the first impurity discharging passage 14 is 4:2:1. With this arrangement, the discharge amount of the sewage can be reduced when various impurities are discharged.
Second, can set up clearance mechanism on box 3 inner wall, through the rotation of precipitation board 4, stir the sediment impurity on the precipitation board 4 and/or the floater under the precipitation board 4 and enter into first through-hole 6 or second through-hole 10. For example:

Further, the inner cavity surface of the box body 3 is provided with a vertical chute, and the sliding block 16 and the sliding rail 15 are arranged in the chute, so that the adhesion of the sedimentation plate 4 and the inner cavity surface of the box body 3 is not hindered.
Referring to fig. 3 and 7, the lower edge of the settling plate 4 is attached to the upper surface of the bottom wall of the box 3, the lower edge of the settling plate 4 has a second impurity discharging channel 19, the second impurity discharging channel 19 is communicated with the main channel 5, impurities on the upper surface of the bottom wall of the box 3 can be discharged by rotating the settling plate 4, and the upper surface of the bottom wall of the box 3 can be cleaned.
Further, referring to fig. 8 and 9, the water outlet 2 is provided with a shutter 21 capable of opening and closing, and when the shutter 21 is closed at the upper end of the water outlet 2, the upper surface of the shutter 21 is flush with the upper surface of the bottom wall of the box 3;

firstly, enabling a water outlet 2 to be in a closed state, opening a water inlet 1, enabling sewage to enter a box body 3 from the water inlet 1, enabling the sewage to slide downwards along a spiral of a sedimentation plate 4 until the sewage is poured into a preset volume of the box body, and separating the sewage into a plurality of containing areas at the moment;
a second step of closing the lower end of the pipe 7 by closing the valve 9, and then pouring a flocculant in a liquid state from the upper end of the pipe 7 into the accommodation area through the first through hole 6, the second through hole 10 and the third through hole 20;
thirdly, precipitation is started, and in each accommodating area, precipitation in sewage can be completed only by falling onto the upper surface of the precipitation plate 4 without falling onto the bottom wall of the box body 3, so that the stroke required by precipitation is shortened, and the precipitation efficiency is improved;
fourth, when the sediment impurities on the upper surface of the sediment plate 4 need to be removed, the pipeline 7 is opened, sewage close to the sediment plate 4 flows into the first through hole 6 under the action of gravity, and the sediment impurities on the upper surface of the sediment plate 4 are driven to enter the first through hole 6, then sequentially pass through the main channel 5 and the pipeline 7, and finally are discharged out of the box body 3;
and fifthly, closing the pipeline 7, opening the water outlet 2, and discharging the precipitated sewage from the water outlet 2.
