Abstract
The utility model discloses a sludge scraping and sucking device for a sedimentation tank, belongs to the technical field of sludge discharge in sedimentation tanks in water supply and sewerage works, and aims to overcome the defects that sludge cannot be discharged thoroughly, the discharged sludge has overhigh water content, water is turbid and the like in a suction dredger and a sludge scraper for sludge discharge in the sedimentation tank at present. The sludge scraping and sucking device comprises a support and a sludge sucking pump, wherein the support is connected with a walking system of a crane, and is provided with a sludge scraping plate, a sludge sucking cover and a sludge sucking tube; the sludge sucking cover is arranged above the sludge scraping plate and is connected with the sludge scraping plate, and is communicated with the sludge sucking tube; two ends of the sludge sucking cover are closed, and the front edge of the sludge sucking cover and a scraping edge of the sludge scraping plate form a sludge suction port; and the outlet of the sludge sucking tube is communicated with the sludge sucking pump. The sludge scraping and sucking device is suitable for horizontal flow sedimentation tanks and inclined tube and inclined-plate sedimentation tanks.
Description
Technical field
The utility model relates to the spoil disposal technology of sedimentation basin in a kind of water supply and sewage work, particularly relates to a kind of sedimentation basin mud and scrapes the suction device.
Background technology
No matter be the mud contamination precipitation pond that in sewage disposal, is used for sedimentation separation sewage; Still in the water treatment with the sedimentation basin of sedimentation separation silt particle, algae; In its production technology, a very important job is arranged, must in time get rid of the mud that is sunken at the bottom of the pond exactly.This be because: in sewage disposal, mud contains the sewage that a large amount of organic matters and all kinds of fungi, mould, especially some food processing enterprises, pharmaceutical industry, grain and oil chemical enterprise are discharged; Mud as untimely handle falls at the bottom of the sedimentation basin is got rid of, and will produce anaerobic fermentation, in mud, produces a large amount of gases; To making the mud come-up; Cause the sedimentation basin can't operate as normal, but also the water quality in the processing is further worsened, the BOD value sharply rises; PH value declines to a great extent, and environment space fills the air harmful foul smell.In giving water treatment, contain a large amount of silt particles and algae in the mud, get rid of like the mud that untimely handle falls at the bottom of the sedimentation basin; Under sunlight and action of temperature; Algae can be in the pond a large amount of growing fast, not only influenced effluent quality, road, back water preparation process can't normally be carried out.At present, in the sedimentation basin type, account in most flat flows, the inclined tube ramp type sedimentation basin, the spoil disposal technology that is adopted generally is to adopt the suction dredge absorption or mud is scraped to sludge sump the method for being drained by discharge pipeline again by mud scraper.According to investigation, suction dredge in absorbing the mud process, exist clod stronger and bigger solid particle to be difficult to exhaust to cohesive force and the mud of discharging in the higher deficiency of moisture content; Mud scraper is in when work, can the disturbance water body, and mud is sneaked in the water purification once more, particularly under the thicker situation of sludge blanket, the mud on upper strata is very easily stirred and is sneaked in the upper water.
Summary of the invention
The purpose of the utility model provides a kind of sedimentation basin mud and scrapes the suction device, overcome clear mud that used suction dredge of present sludge from sedimentation tank and mud scraper exist not thoroughly, the moisture content of discharging mud is too high, will disturb deficiency such as muddy water body.
The utility model is achieved through following technical proposals.
The utility model comprises support, dredge pump, and the running gear of said support and driving is connected, and is provided with cleaning shoe, mud sucking cover and dredging tube, and said mud sucking cover is loaded on the top of said cleaning shoe and interconnects also and is communicated with said dredging tube; Said mud sucking cover, its two ends are that the tooth shape of scraping sealing, its front and said cleaning shoe becomes suction mud mouth; The outlet of said dredging tube is communicated with said dredge pump.Clearly, the utility model is that the effective structure in existing suction dredge technology and the mud scraper technology is optimized combination, thereby has produced new technical scheme.The effect of said cleaning shoe is thoroughly to sweep the mud that is deposited at the bottom of the sedimentation basin pond, and the effect of said mud sucking cover is that the mud that sweeps said cleaning shoe can not stirred again and sneaks into water body; Said suction mud mouth can make the water yield that is inhaled into be effectively controlled, and has not only made that to contain in moisture content that the help that is necessary flows but also the mud that can not cause discharge moisture content in the mud that is excluded too high; The shape of said suction mud mouth is preferably used scrak type.
In order to make said dredging tube laterally maintain negative pressure uniformly to said mud sucking cover, the lower end of said dredging tube is connected with inhales the mud transverse tube, in inhaling at least two suction mud arms is housed evenly distributedly on the mud transverse tube, on the said suction mud arm pressure-regulating valve is housed.For make said cleaning shoe and mud sucking cover etc. under water parts can on the sedimentation basin bottom surface, move smooth and easyly, two following ends of said mud sucking cover are equipped with road wheel.
Against existing technologies, the beneficial effect of the utility model is:
Avoid sedimentation basin when spoil disposal is operated to the disturbing of mud, reduce the water content of discharging mud, improve spoil disposal efficient.
Description of drawings
Fig. 1 is the structural representation of the utility model, and Fig. 2 is the A-A cut-away view of Fig. 1, and Fig. 3 is the axonometric drawing of dredging tube, suction mud transverse tube, suction mud arm etc.Among the figure: 1, support, 2, cleaning shoe, 3, mud sucking cover, 4, dredging tube, 5, inhale the mud mouth, 6, inhale the mud transverse tube, 7, inhale the mud arm, 8, pressure-regulating valve, 9, road wheel.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further to describe.
The utility model is applicable to the sedimentation basin of flat flow and inclined tube ramp type water supply and sewage work.Can dock with many prior aries during enforcement, like truss driving, drive unit, transmission device, spoil disposal pipe-line system etc.In the fabrication and installation process, can carry out according to diagram and water supply and sewage work construction technique normalizing.After fabrication and installation were good, the open degree of answering pressure control valve 8 was regulated, and the negative pressure that makes 7 pairs of mud sucking covers 3 of each suction mud arm about equally.When the utility model is implemented operation; Open the running gear and the dredge pump of driving, at this moment, support 1 drive cleaning shoe 2 shovels forward with mud sucking cover 3 scrapes sludge blanket; A large amount of mud is swept and gets into mud sucking cover 3 by shovel, siphoned away through suction mud transverse tube 6, suction mud arm 7 by dredging tube 4.In operation process, there are the current of very small amount to sneak into mud by inhaling mud mouth 5 entering mud sucking covers 3, siphoned away together.It has two effects: the one, remove a small amount of mud that cleaning shoe 2 is stirred when scraping mud, the unlikely water body of sneaking into; The 2nd, mud there is lubrication, help flowing of mud.But from the water yield of inhaling 5 entering of mud mouth is fewer, and this is because cleaning shoe 2 continues to shovel most spaces that the mud that sweeps has occupied mud sucking cover 3, has only the entering of volume permission current seldom, so water content is lower in the mud that can guarantee to discharge.
