The central drive sludge scraper adopts central drive and suspension type. After the sewage flows into the diversion tube from the inlet pipe under the working bridge and diffuses, it flows out evenly and radially to the periphery. The suspended sludge is deposited on the bottom of the pool after sedimentation. The drive The device drives the central vertical shaft to rotate, and drives the scraper arm and scraper plate to rotate. After scraping the sludge from the periphery of the pool to the central sludge collection tank, it is discharged out of the pool through the sludge discharge pipe based on the hydrostatic pressure in the pool. The skimming device skims toward the edge of the pool, and then scrapes the slag rake into the slag discharge hopper and discharges it out of the pool; while the supernatant liquid overflows into the outlet water tank through the triangular outlet weir plate and is discharged.
Main features of the equipment:
- The driving device adopts a three-stage cycloidal pinwheel reducer, which has stable transmission, compact structure and high mechanical efficiency;
- The lower end of the vertical shaft of the mud scraper is equipped with an underwater support to avoid deflection when the vertical shaft rotates;
- Set up mechanical and electronic double overload protection to ensure safe and reliable operation;
- The equipment is easy to operate and can directly control the operation of the equipment locally/remotely.
The ZBG peripheral transmission mud scraper is mainly composed of a flow stabilizing cylinder, a power collecting device, a central support, a working bridge (main beam), a mud scraping mechanism, a slag discharge mechanism, a driving device, a traveling device and an electric control box.
Peripheral transmission sludge scraper is a sedimentation tank sludge scraping equipment commonly used in urban water plants and urban sewage treatment plants. The middle water inlet, mud discharge, and peripheral drainage are used to ensure uniform water flow. The liquid level difference is used to self-priming mud discharge, and it has a scum scraping and removal device and an overload protection device; the control system can be connected to the computer network according to user requirements.
It mainly consists of a driving mechanism, a main beam, a central rotating support, a guide tube, a mud scraping system, a slag discharge bucket and a flushing mechanism, an articulated scraper rake, a skimming plate, a skimming bucket, a water outlet triangular edge plate, and scum. It is composed of baffle, control box and other components.
The machine is mainly composed of main beam, center support, transmission device, scraper arm, bottom scraper, scum scraper, flow stabilizer, scum funnel and other components. The main beam is supported by the pier in the center of the pool and the wheels running on the edge of the pool. The center of the main beam is hinged with the central support on the central pier, and transmission devices including reducers are installed at both ends. The machine uses the central support on the pier as the axis to rotate along the circumference of the pool. A scraping device is installed at the bottom of the main beam. The scraper at the bottom scrapes the sludge at the bottom of the pool into the mud discharge trough in the center of the pool. The sludge is discharged out of the pool through the mud bucket scraper at the bottom. .
After the sewage diffuses from the water inlet pipe in the center of the pool through the diversion tube, it flows out evenly and radially to the periphery. The suspended sludge is deposited at the bottom of the pool after sedimentation. The supernatant liquid is discharged from the pool through the overflow weir plate and out of the water tank. Outside, the sludge scraper scrapes from the periphery of the pool to the central sludge collecting tank, and is discharged out of the pool through the sludge discharge pipe relying on the water pressure in the pool. Driven by the peripheral driving device, the main beam travels along the top of the pool at a linear speed of 2.0m/min with the central rotating support as the axis. The lower part of the main beam is connected to brackets, sludge scrapers, etc. A scum scraper is installed near the liquid surface, extending along the central flow tube to the hinged scraper rake. When the main beam rotates, the scum scraper skims the scum on the liquid surface from the center of the pool to the periphery of the pool, and collects it in the hinged scraper rake. In the scraper rake area, the collected scum moves with the main machine around the pool to the skimmer hopper. It is scraped into the skimmer hopper through the hinge movement of the scraper rake and discharged outside the pool.
The central support is composed of a fixed support base, a slewing bearing and a frame, and can withstand axial force, radial force and overturning moment at the same time. The current collecting device adopts a slip ring type current collecting device, which is composed of a collecting ring and a brush holder. The floating pool scraper, scum rake plate and scum funnel form a scum discharge mechanism, which can effectively remove scum from the water surface. The working bridge is a large component that connects the central support and the traveling end beam. There are walkway plates and railings on it. The bottom of the steel beam is connected to the mud scraping structure, slag discharging mechanism, etc. The working bridge is driven by the traveling device to complete the mud scraping and slag discharging work. .
The raw water flows out from the bottom of the pool through the upper part of the central pier, and after being distributed through the flow stabilizing tube, it flows radially to the water collection tank around the pool. As the radial flow rate decreases, the suspended matter in the raw water is separated and settles at the bottom of the pool. The working bridge takes the central support as the center of the circle and drives the sludge scraping and slag discharge mechanism. Driven by the driving device, the sludge is scraped and collected into the sludge collecting tank in the center of the sedimentation tank. It is discharged out of the tank by water pressure or a pump. The upper scum is scraped by the sludge scraper. Simultaneously scrape it to the slag discharge bucket and discharge it.
The driving device pushes the working bridge to rotate along the plane of the pool, and the working bridge drives the scraper arm to rotate. The scraper fixed on the scraper arm gradually scrapes the mud from the edge of the pool to the mud collecting bucket in the center of the pool. The curve of the scraper is a logarithmic spiral line. , the force is evenly distributed, and the mud is scraped thoroughly. When there are obstacles at the bottom of the pool, it can automatically rake to protect the machine from damage. The driving device can be equipped with a torque protection device to make the work safer.
main feature:
- The transmission device has been optimized and designed with higher efficiency and more beautiful appearance. It can be equipped with imported reducer or shaft-mounted reducer according to user requirements, which is more beautiful and durable.
- This equipment has a large processing capacity and good sludge scraping effect.
- The equipment has a compact structure, small floor space, and easy operation and maintenance.
- The equipment operates smoothly, scraping mud and scum can be carried out at the same time, saving energy.
The sludge scraper should always check the mud suction machine, the smoothness of the mud suction pipe, and the gas volume of the gas pipe, and adjust them to the best condition. Our company provides one-year warranty and maintenance services, and has a dedicated technical team to support it, so that your mud scraper can work fully and efficiently, saving time and maximizing benefits.
