Description
Technical Field
The utility model belongs to the sewage treatment device field, concretely relates to gravity type mud scraper.
Background
A peripheral transmission mud scraper is a common mud scraping device for a sedimentation tank of a municipal water plant and a municipal sewage plant. Its main function is to collect the sediment that subsides on the bottom of the pool to the mud collection hole of bottom of the pool through the mud scraper of mud scraper bottom, prevents the bottom of the pool jam via agitating unit, and the mud pipe of bottom of the pool is outside with sediment discharge pond. The floating slag on the surface of the pool is scraped into a slag discharge hopper through a slag scraping plate and is discharged into a slag floating well outside the pool through the slag discharge hopper. The disturbance to the water flow is very small, and the sludge discharge effect is good.
Because the mud scraper is not working constantly, if the mud scraper is not treated for a long time, the sediment at the bottom of the pool can be increased and thickened, the too thick sediment can cause the mud scraper to be incapable of advancing under the action of the driving device, so that the advancing wheel set at one side of the working axle slides and rotates, namely the driving device drives the complete machine to rotate. If the power of the driving motor is increased, the scraping arm is easy to break under the condition that the mud scraping plate cannot advance. At present, some mud scrapers control the height of the mud scraper through hydraulic pressure to enable the mud scraper to rise to the uppermost layer of the mud, but the hydraulic pressure control can not be carried out manually to accurately control the most proper position of the mud scraper, and the effective scraping of the mud is not facilitated.
Disclosure of Invention
An object of the utility model is to overcome prior art's shortcoming, provide a gravity type mud scraper, solved the scraping arm device fragile that bottom of the pool mud leads to excessively thick and the technical problem that drive arrangement does not drive the complete machine.
In order to achieve the above purpose, the utility model adopts the technical scheme that:
a gravity type mud scraper comprises a sedimentation tank, a driving device, a sewage inlet pipe, a central support, a steady flow cylinder, a scum baffle, a skimming device, a stirring device and a working bridge, wherein the working bridge is driven by the driving device to rotate around the central support; wherein: the gravity type mud scraper also comprises a scraping arm device arranged below the working bridge and a bottom scraping plate arranged below the scraping arm device;
the scraping arm device comprises a plurality of industrial connecting iron chains;
be equipped with two connection iron chains on a set of bottom scraper blade, two the lower extreme of connecting the iron chain respectively with the both ends of bottom scraper blade are connected, two the upper end of connecting the iron chain is connected with the both sides of working bridge width direction respectively, makes a plurality of be parallel to each other just between the bottom scraper blade the contained angle between the projection position of bottom scraper blade and working bridge is the acute angle.
Further, the area of the bottom scraper plate closer to the center of the pool is larger than the dead weight, and a sludge scraping overlapping part is arranged between the adjacent bottom scraper plates.
Furthermore, the lower edge of the bottom scraper is parallel to the pool bottom, and a gap is arranged between the lower edge of the bottom scraper and the pool bottom.
The utility model adopts the above technical scheme to realize the high position of mud scraping device automatic adjustment bottom scraper blade, scrape the arm device and use the connection iron chain to connect the bottom scraper blade, it is rotatory under the drive of work bridge to connect the iron chain, because the flexible action of connecting the iron chain, it extracts the bottom scraper blade from the precipitate of excessive thickness to connect the iron chain, again because the action of gravity of bottom scraper blade, the bottom scraper blade can fall in the superiors of precipitate, every has scraped the round, the bottom scraper blade can continue to fall the superiors of precipitate under the effect of gravity, and then realized striking off layer upon layer to the precipitate, the condition that the bottom scraper blade can't scrape the sediment of moving excessively thick and cause the mud scraper to damage has been avoided.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a top view of fig. 1.
Detailed Description
The present invention will be further explained with reference to the drawings and examples.
As shown in fig. 1 to 2, a gravity type mud scraper in this embodiment includes a sedimentation tank, a driving device, a sewage inlet pipe, a central support, a flow stabilizing cylinder, a scum baffle, a skimming device, a stirring device, and a working bridge, wherein the working bridge is driven by the driving device to rotate around the central support; wherein: the scraper arm device 1 is arranged below the working bridge, and the bottom scraper plate 2 is arranged below the scraper arm device;
the scraping arm device 1 comprises a plurality of industrial connecting iron chains 1-1;
be equipped with two connection iron chains 1-1 on a set of bottom scraper blade 2, two the lower extreme of connecting iron chain 1-1 is connected with the both ends of bottom scraper blade 2 respectively, two the upper end of connecting iron chain 1-1 is connected with the both sides of working bridge width direction respectively, makes a plurality of be parallel to each other just between bottom scraper blade 2 and the projecting position of working bridge contained angle between 2.
Further, the area and the dead weight of the bottom scraping plate 2 which is closer to the center of the pool are larger, and a mud scraping overlapping part is arranged between the adjacent bottom scraping plates 2.
Further, the lower edge of the bottom scraper 2 is parallel to the pool bottom, and a gap is arranged between the lower edge and the pool bottom.
Sewage enters the flow stabilizing cylinder through the sewage inlet pipe above, and precipitates in the sewage fall into the bottom of the tank after water is distributed by the flow stabilizing cylinder. When sediment at the bottom of the tank needs to be removed, the working bridge drives the scum baffle, the skimming device and the scraping arm device 1 by taking the central support as the center of a circle, the sediment is scraped and collected to the central mud collecting groove of the settling tank under the driving of the driving device, the sediment is discharged out of the tank by water pressure or a pump, and the upper scum is synchronously scraped to the scum discharge hopper by the scum baffle and is discharged. Under the condition that the sediment is thick, the upper part of the connecting iron chain 1-1 moves along with the working bridge, the lower part of the connecting iron chain 1-1 drives the bottom scraper blade 2 to pull the bottom scraper blade out of the sediment, the bottom scraper blade 2 falls on the uppermost layer of the sediment to scrape, and when one layer is scraped, the bottom scraper blade 2 can automatically fall on the uppermost layer of the residual sediment, so that the sediment can be scraped layer by layer.
