The reducer of the scraper is a driving device that adopts a single-stage worm gear reduction transmission. It can be driven by a cycloid pinwheel reducer and a speed regulating motor through a sprocket chain, a V-belt pulley or directly connected. This equipment is a low-speed output transmission device with large output torque, low noise, stable operation and no leakage. It is mainly used as a supporting product for mud removal machinery of water treatment equipment. The reducer has manual lifting and hand-electric dual-use lifting forms. Safety shear pins and spring-type over-torque automatic protection devices can be added according to user requirements to ensure the safe operation of the entire set of equipment.
Detailed introduction of JWZ scraper Scraper is a kind of mud discharge equipment. Components: The scraper is composed of a gantry truck, a scraper rake, a skimming plate, a drive device and an automatic control cabinet. The scraper mainly includes a central drive scraper and a peripheral drive scraper. The central drive scraper is mainly composed of a working bridge, a transmission device, a flow stabilizer, a transmission shaft, a scraper arm, a scraper plate, etc. The machine is equipped with a fixed platform across the pool. When working, the load of the whole machine acts on the center of the working bridge; the sewage flows to the surroundings through the center flow stabilizer of the pool. As the flow area increases and the flow rate decreases, the sediment in the sewage settles at the bottom of the pool. The scraper scrapes the precipitated sludge into the central mud collection pit and discharges it from the sludge pipe by water pressure. The reducer of the scraper adopts worm gear drive, which has stable transmission and large transmission torque, and the structure is reasonably applied to the scraper.
Designed for thickeners and mixing equipment, this reducer can provide stable and efficient power transmission. Its unique worm gear structure not only improves work efficiency, but also greatly extends its service life. Whether it is a sewage treatment plant or a chemical enterprise, it can perfectly cope with various complex working conditions.
When it comes to performance, the 1:1.5 speed ratio of this reducer makes it stand out from similar products. The cast iron material ensures durability, and the four-mode parallel reversing design further enhances the flexibility and stability of operation. Whether in harsh working environments or long-term continuous operation, it can maintain excellent performance.
The specifications of JWZ manual lifting scraper special reducer are mainly JWZ200\JWZ2410\JWZ350\JWZ460, etc. Choose the appropriate worm gear box according to the size of the clarifier. The following data is for reference only:
Diameter 6 meters: choose JWZ200-8-40-ST(DT)
Diameter 8 meters: choose JWZ240-10-40-ST(DT)
Diameter 10 meters: choose JWZ350-10-60-ST(DT)
Diameter 16 meters: choose JWZ460-10-60-ST(DT)
Each of the above models can be equipped with an overload protection device, and manual lifting (ST) or electric lifting (DT) can be customized according to customer needs.
The first-stage reduction motor usually uses a double-machine cycloid pinwheel reducer, and a suitable reduction motor is selected according to different specifications of the worm gear box. The same worm gear reducer is connected by a sprocket chain.
Center drive scraper
