Abstract
The utility model relates to a kind of sedimentation basin dross skimming device, including sedimentation basin and sewer catch basin, the bottom of the sedimentation basin is equipped with mud-collecting slot, further includes: dross bucket and for adjusting dross bucket in the lifting device of sedimentation basin inner height；The bottom of the dross bucket is connected to by hose and the first valve with sewer catch basin, and the mud-collecting slot is connected to by pipeline and the second valve with sewer catch basin；It is equipped with sewer catch basin level sensing in the sewer catch basin and shows equipment；The utility model can effectively exclude the dross or mud scum of precipitating pool surface, influence of the accumulation of the loss and dross that reduce mud scum to the treatment effect and effluent quality of sedimentation basin, while meet the needs of process operation sludge reflux.
Description
Technical field
The utility model belongs to detention tank processing equipment field, in particular to a kind of sedimentation basin dross skimming device.
Background technique
In sewage treatment process, the setting of sedimentation basin is essential, and the main function of sedimentation basin is mud-water separation, a side
Face guarantees the clarification of water outlet, and on the other hand because of the requirement of process operation, the sludge of precipitating needs to flow back, to guarantee the effect of processing
Fruit.
Sludge or the anaerobic effluent band mud etc. for being directed to corruption easy to ferment can form mud scum or dross in precipitating pool surface
The case where, if do not collected in time to mud scum or dross, it will lead to sedimentation basin surface and accumulate a large amount of mud scums or dross, and more collecting
Thickness, and then influence effluent quality.
In addition to this, the sludge for the corruption easy to ferment that usual sedimentation basin surface is accumulated, is handled, no as dross or rubbish
Be back to front-end process unit, and be formed by mud scum in precipitating pool surface when anaerobic effluent band mud, property substantially with it is heavy
Shallow lake bottom of pond portion sludge quality is similar, and needing to flow back reenters system, can not such as collect, with being constantly lost, final system
Treatment effect can be caused to be deteriorated because of the continuous reduction of sludge concentration.
Utility model content
The technical problem to be solved by the present invention is to fill up the deficiencies in the prior art, providing one kind can a kind of sedimentation basin
Dross skimming device can exclude recycling to dross or mud scum in time, reduce the loss of mud scum and the accumulation of dross to sedimentation basin
Treatment effect and effluent quality influence, while meeting the needs of process operation sludge reflux.
For this purpose, the utility model concrete scheme is as follows:
The bottom of a kind of sedimentation basin dross skimming device, including sedimentation basin and sewer catch basin, the sedimentation basin is equipped with mud-collecting slot,
Further include: dross bucket and for adjusting dross bucket in the lifting device of sedimentation basin inner height；The bottom of the dross bucket passes through
Hose and the first valve are connected to sewer catch basin, and the mud-collecting slot is connected to by pipeline and the second valve with sewer catch basin；The sludge
It is equipped with sewer catch basin level sensing in well and shows equipment.
Further, the lifting device includes the promotion track along precipitating pool wall setting, and is mounted on sedimentation basin top
Loop wheel machine；The dross bucket, which is movably connected on, to be promoted on track and is connect with the suspension hook of loop wheel machine.
Further, first valve and the second valve are manually or electrically valve.
The utility model has the beneficial effects that:
The utility model can precipitate the second valve on bottom of pond portion mud-collecting slot and sewer catch basin connecting pipe by start and stop, with
The mud position in sewer catch basin is controlled, using the liquid level difference of precipitating pool water level and height-adjustable dross bucket, makes dross or mud scum certainly
It is dynamic to enter dross bucket, it then flows into sewer catch basin, so as to effectively exclude the dross or mud scum of precipitating pool surface, reduces floating
The influence of the loss of mud and the accumulation of dross to the treatment effect and effluent quality of sedimentation basin, while meeting process operation sludge and returning
The demand of stream.
Detailed description of the invention
Fig. 1 is the planar structure schematic diagram of the utility model；
Fig. 2 is in Fig. 1 along the face A-A cross-sectional view；
Fig. 3 is in Fig. 1 along the face B-B cross-sectional view；
Fig. 4 is in Fig. 1 along the face C-C cross-sectional view；
Wherein: 1- dross bucket, 2- hose, 3- sewer catch basin, the second valve of 4-, 5- pipeline, the first valve of 6-, 7- promotion are led
Rail, 8- loop wheel machine, 9- sedimentation basin, 10- mud-collecting slot.
Specific embodiment
The utility model is described in further details combined with specific embodiments below.
A kind of sedimentation basin dross skimming device referring to figs. 1 to 4, including sedimentation basin 9 and sewer catch basin 3 are described heavy
The bottom in shallow lake pond 9 is equipped with mud-collecting slot 10.
It further include dross bucket 1 and for adjusting dross bucket 1 in the lifting device of 9 inner height of sedimentation basin.
Lifting device in the present embodiment includes the promotion track 7 along the setting of 9 wall of sedimentation basin, and is mounted on sedimentation basin 9
The loop wheel machine 8 on top, the dross bucket 1, which is movably connected on, to be promoted on track 7 and is connect with the suspension hook of loop wheel machine 8；With the driving of loop wheel machine 8,
Dross bucket 1 will rise or fall along track 7 is promoted, to adjust the liquid level above and below that dross bucket 1 is located in sedimentation basin 9.
The bottom of the dross bucket 1 is connected to by hose 2 and the first valve 6 with sewer catch basin 3, and the mud-collecting slot 10 passes through pipe
Road 5 and the second valve 4 are connected to sewer catch basin 3.First valve 6 and the second valve 4 are using manually or electrically valve.
Meanwhile it being additionally provided with sewer catch basin level sensing in the sewer catch basin 3 and shows that equipment (can refer to existing level sensing
Equipment, the present embodiment are no longer described in detail), sewer catch basin level sensing shows equipment for guaranteeing dross or mud scum and bottom mud-collecting slot 10
Sludge discharge when, sedimentation basin 9 can be normally discharged.
The operating method of the utility model is as follows:
The second valve 4 between mud-collecting slot 10 and sewer catch basin 3 in connecting pipe 5 is closed, the sludge in sewer catch basin 3 is dirty
Dredge pump extraction, reduces the mud position in sewer catch basin 3, then adjusts height of the dross bucket 1 in sedimentation basin 9 by lifting device, makes
Dross bucket 1 is in 9 water level of sedimentation basin hereinafter, using the liquid level difference between the water level of sedimentation basin 9 and the mud position of sewer catch basin 3, precipitates
The dross or mud scum on 9 surface of pond are then automatically flowed into sewer catch basin 3 by the hose 2 that dross bucket 1 is connected with sewer catch basin 3, when not
When needing to be discharged the mud scum on 9 surface of sedimentation basin or having drained mud scum, the first valve 6 that soft road 2 connects is closed, sedimentation basin 9 is prevented
Supernatant enter sewer catch basin 3；So under operation, the dross or mud scum on 9 surface of sedimentation basin can be effectively excluded.
The preferable specific embodiment of the above, only the utility model, but scope of protection of the utility model is not limited to
In this, anyone skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, should be covered within the scope of the utility model.Therefore scope of protection of the utility model is with claim
