Suspended Center Drive Mud Scraper
The suspended center drive mud scraper is mainly composed of deceleration drive mechanism, transmission vertical shaft, scraper arm, underwater bearing and mud collecting tank scraper. The load of the whole mud scraper acts on the center of the working bridge fixed across the pool diameter. The raw water flows radially to the overflow tank around the tank after being simply distributed through the central water distribution. With the decrease of flow rate, the suspended solids in the water body are separated and settled at the bottom of the tank. Through deceleration drive and transmission of suspension components, the sludge is scraped and collected to the central sludge tank by scraper and discharged out of the tank by hydrostatic force or pump.

Peripheral Drive Mud Scraper
The peripheral drive mud scraper is mainly composed of central rotating support, main beam (truss beam, folded plate beam), guide cylinder, mud scraper, slag scraper, power collector, driving mechanism, etc. The raw water flows out from the bottom of the pool through the upper part of the central pier, and after water distribution through the diversion cylinder, it flows radially to the water collecting tank around the pool. With the decrease of radial velocity, the suspended solids in the raw water are separated and settled at the bottom of the pool. The rotating truss takes the central support as the center, and the end walking wheel rotates along the circumference of the tank under the action of the driving device to drive the lower mud scraper to rotate slowly, scrape and collect it to the central mud collecting tank of the sedimentation tank, discharge it out of the tank by hydrostatic pressure or pump, and the upper scum is scraped to the slag bucket by the slag scraper.

Peripheral Drive Mud Scraper Suction Machine
HXB type peripheral drive mud scraper and suction machine mainly includes main beam (truss beam or folded plate beam), overflow weir, transmission device, steady flow cylinder, central mud tank, mud discharge tank, scraper, mud suction device, Scum Collection and removal facilities and power transmission device. The water to be treated enters from the inlet pipe of the central cylinder, flows steadily into the sedimentation tank through the flow stabilizing cylinder, and then diffuses and precipitates around. The clean water flows out of the overflow weir at the side of the tank, in which the sediment is scraped and collected to the mud suction port by the mud scraper. According to the principle of connecting pipe, the sludge at the bottom of the tank is sucked into the sludge discharge tank by using the water level difference; It enters the central cylinder through the siphon and is discharged through the sludge discharge pipe. At the same time, the scum in the tank is collected by the scum scraper and discharged out of the tank through the slag bucket.

Center Driven Tubular Mud Suction Machine
The central transmission single (double) pipe mud suction machine is mainly composed of central transmission device, central vertical frame, mud suction pipe, slag scraping plate, truss, scum scraping and collecting device, working bridge, water retaining skirt, scum bucket, etc. When the sludge mixture enters the water inlet tank, it evenly enters the tank through the water distribution hole pipe at the bottom of the tank. Under the action of the water retaining skirt, the water flows slowly and evenly from the bottom of the surrounding tank to the center of the tank in the state of density flow. At the same time, the sludge begins to settle at the bottom of the tank under the action of gravity to form a high concentration primary sludge layer, The separated clarifier flows to the lower part and returns to the surrounding outlet tanks and is discharged out of the tank through the outlet pipe. Under the action of liquid level difference, the activated sludge on the surface of the tank bottom is collected and discharged out of the tank through the orifice on one side of the sludge suction pipe.

The heavy emotional sludge is scraped to the sludge pit in the center of the tank by the scraper plate and discharged out of the tank through the sludge discharge pipe. The scum on the tank surface is skimmed into the scum bucket through the scraper device Discharge outside the tank.

Skimming (oil) Mud Scraper
Skimming (oil) mud scraper is divided into two types according to process structure and working mode. HGH-T type lifting plate collecting (oil) scraper is an integral device mainly composed of driving reducer, slag skimming mechanism, sludge discharge mechanism, lifting drum and electric control device on the truss frame. Under the command of the electric control device, the slag skimming and mud scraping mechanism runs back and forth along the straight line laid on the pool surface with the truss frame. Lift or lower the scraper when the lifting and falling coil is simply fixed (fixed range), so that the skimming and mud scraping work in one direction respectively, scrape and collect the sludge at the bottom of the tank and the oil residue on the liquid level respectively outside the sludge collecting tank and the oil drain pipe. Hgh-l chain traction skimmer (oil) scraper is mainly composed of deceleration drive device fixed on the pool surface, traction chain with scraper in the pool, transmission chain pair and tensioning device, safety protection device, etc.

Hydraulic Reciprocating Mud Scraper
Working principle of the mud scraper: the gear oil pump provides power to the hydraulic oil cylinder, a group of tripod converts the vertical motion of the oil cylinder into horizontal motion, and finally drives a group of wedge scrapers to make reciprocating motion at the bottom of the rectangular tank; The reciprocating stroke is greater than the spacing of a single scraper, which is equivalent to the sludge transfer from the latter scraper to the front scraper; The forward speed of the scraper group is about half of the backward speed; When moving forward, the concave surface of the wedge-shaped scraper pushes mud to the mud accumulation ditch of the pool; When retreating, a small wedge-shaped acute angle will not drive the sludge to move backward, while the negative pressure generated by the rapidly retreating concave surface will keep the forward inertia of the sludge layer with a certain thickness.

Monorail Underwater Mud Scraper
Monorail underwater mud scraper is applicable to the mud scraping of rectangular sedimentation tank in large water supply plant or sewage treatment plant. The underwater mud scraper scrapes the sludge at the bottom of horizontal sedimentation tank from the water outlet area to the water inlet area, and finally scrapes the sludge to the sludge sump in the water inlet area for centralized discharge, instead of the traditional siphon mud extractor with suction while walking. Composition structure: The mud scraper is mainly composed of traction ring chain, mud scraper trolley mechanism, sprocket and sprocket frame, pool bottom track and fixing device, drive guide sprocket, overload protection device, cable chain tensioning device, forward and reverse control device, driving device protection cover, electrical control cabinet, central deceleration drive device, limit device, etc. The main components of monorail underwater mud scraper are: transmission components, mud scraper trolley components, track components, guide wheel groups at both ends, tensioning device and electric control components.
