Urban sewage treatment plant Non-metallic chain mud scraper Manufacturer Chain plate slag scraper
The chain type oil scraper is the supporting equipment of the sedimentation tank in the sewage treatment, and is a professional product developed by our company. The chain type oil scraper is specially designed to remove grease, colloid and sludge at the bottom of the tank in industrial and urban sewage. The chain oil scraper has the characteristics of adjusting measures to local conditions, flexible slag removal control, stable operation, convenient operation, simple maintenance and long service life.
Working Principle
1. The chain mud scraper continuously removes the suspended solids floating on the water surface and the sludge at the bottom of the tank, moves along the tank surface and bottom, and pushes the suspended solids from the inlet end of the liquid level to the outlet end. It can be used for skimming and bottom scraping of the inner surface of rectangular primary sedimentation tank and secondary sedimentation tank, as well as skimming of various tank body shapes. It has been widely used in the water treatment industry in recent years.
2. Driven by the peripheral driving device, the main beam is driven along the tank top at a linear speed of 2.0m/min with the central rotating support as the axis, and the lower part of the main beam is connected with the support, sludge scraper, etc. The scum scraper is set near the liquid level and extends along the central stabilizer to the hinged scraper. When the main beam rotates, the scum scraper skims the scum on the liquid level from the center of the pool to the periphery of the pool and collects it in the hinged scraper area. The collected scum moves to the skimming bucket along with the main machine around the pool, scrapes it into the skimming bucket through the hinge of the scraper and discharges it outside the pool.
3. When the scraper moves back and forth, a layer of sludge at the bottom of the tank always moves forward until it falls into the sludge collecting ditch. The reciprocating movement of the scraper also has the function of thickening sludge, which is particularly important in practical applications. When the amount of sewage is equal, the higher the concentration of sludge, the lower the water consumption rate, which also reduces the loss of water and energy.
Product Features
1. Good installation quality, easy maintenance and long service life.
2. Energy saving, plastic parts are light and easy to move, and power consumption is small.
3. The idler wheel (guide wheel) can be adjusted for calibration. The length between chains can also be adjusted according to the chain pitch.
4. The plastic bottom rail mud scraper can prevent derailment and can be adjusted for minor problems.
5. Low energy consumption and low operating cost.
