Abstract
The invention discloses a double-periphery transmission mud scraper, in particular to a double-periphery transmission mud scraper which is suitable for a circular sedimentation tank in the sewage treatment process, and comprises a sedimentation tank, a walkway, a travelling mechanism, travelling wheels, bridge frames, a central support and hinges, wherein two groups of hinges are arranged on the central support, the bridge frames are divided into two sections, one end of each section of bridge frame is connected with the hinge on the central support, the other end of each section of bridge frame is connected with the travelling mechanism, and each section of bridge frame can rotate up and down around the connected hinge.
Description
The technical field is as follows:
the invention relates to the field of environmental protection, in particular to a double-periphery transmission mud scraper which is suitable for a circular sedimentation tank in a sewage treatment process.
Background art:
in the field of sewage treatment, mud scrapers are widely used in sedimentation tanks for discharging sludge settled on the bottom of the tank to the outside of the tank. When the design of the circular sedimentation tank is carried out, the fact that the peripheral walkways of the circular sedimentation tank are smooth and are in the same plane with the top of the central island at the center of the tank can be guaranteed during construction, in the actual construction process, due to the construction process level, the ground subsidence and other reasons, the peripheral walkways of the sedimentation tank are not flat integrally, even in some steel sedimentation tanks, the walkways are wavy, the bridge frame of the mud scraper is an integral steel structural member, the two ends of the bridge frame are respectively provided with the walking mechanisms, and the middle of the bridge frame is connected with the central support on the upper side of the central island through hinges. When mud scraper walked on the sedimentation tank pavement, when the pavement at crane span structure both ends was all high, can make the center support receive extra pulling force, made the life-span of center support shorten, damaged in advance even: when the walkways at two ends or one end of the bridge frame are low, the walking wheels at two ends or one end can be attached to the walkways not tightly, so that the friction force between the walking wheels and the walkways is reduced, the problem that the mud scraper cannot walk due to the resistance of the sludge at the bottom of the sedimentation tank to the mud scraper can not be solved, and if the sedimentation tank is restored to the design requirement, the manufacturing cost of the sedimentation tank can be greatly increased, and the construction period can be delayed.
The invention content is as follows:
the invention aims to design a mud scraper which can adapt to the overall unevenness of a walkway of a circular sedimentation tank.
1. The technical scheme for realizing the purpose of the invention is as follows: the utility model provides a mud scraper is scraped in transmission of double circumference, includes sedimentation tank, pavement, running gear, walking wheel, crane span structure, central support, hinge, its characterized in that central support on arrange two sets of hinges, the crane span structure is two, the one end of every section crane span structure and the hinged joint on the central support, the other end is connected with running gear, every section crane span structure all can be around the hinge that is connected from top to bottom rotating, every group symmetrical arrangement of hinge is 2, leave the clearance that is not less than 50mm between two sections crane span structures.
Compared with the prior art, the invention has the obvious advantages of strong adaptability to the sedimentation tank and long service life.
Description of the drawings:
FIG. 1 is a schematic view of the structure of the present invention
FIG. 2 is a schematic view of the bridge, hinge, center support connection of the present invention (with section view)
FIG. 3 is a side view of the bridge, hinge, center pedestal connection of the present invention
The specific implementation mode is as follows:
in order to solve the defects of high manufacturing requirement and high cost of the existing mud scraper on a sedimentation tank, the invention adopts the following technical scheme that two groups of hinges 6 (two groups of two groups are symmetrically arranged) are arranged on a central support 7, a bridge 5 is made into two sections, one end of each section of bridge is connected with the hinge on the central support, the other end of each section of bridge is connected with a travelling mechanism 4, and each section of bridge can rotate up and down around the connected hinge.
The working principle is as follows: the walking wheels 3 of the walking mechanism of the mud scraper are in contact with the walkway 2 of the sedimentation tank 1, and the friction force between the walking wheels and the walkway is utilized to overcome the resistance of the sludge at the bottom of the sedimentation tank to the mud scraper, so that the mud scraper is driven to rotate along the sedimentation tank, the sludge deposited at the bottom of the tank is scraped to the center of the tank, and then the sludge is discharged out of the tank. When the walking mud scraper walks to a lower place of the walkway of the sedimentation tank, the mud scraper enables the bridge frame of the mud scraper to rotate downwards around the hinge on the central support by means of the self weight, so that the walking wheels are always attached to the walkway, and the mud scraper is driven to normally walk. On the contrary, when the walking wheel walks to a higher place of the sedimentation tank walkway, the bridge frame of the mud scraper rotates upwards around the hinge on the central support, so that the walking wheel can be attached to the walkway, and the mud scraper is driven to normally walk. Because the bridge frame is two-section, the bridge frame can freely rotate around the hinge corresponding to the central support. Therefore, no matter the walkways at one end of the bridge frame are higher or lower, or the walkways at two ends of the bridge frame are simultaneously higher or lower, the travelling wheels can be tightly attached to the walkways, and the normal operation of the mud scraper is ensured.
Claims (3)
