1, overview

Driving type scraping mud machine is applicable to water supply and drainage engineering of the advection type sedimentation tank, the sedimentation in the bottom of the pool of sludge scraping set to the mud collecting groove and the pool surface skimmer to the slag collecting chute. According to the requirements of the user set scum scraper. According to the direction of water flow, can be divided into reverse scraping reverse and reverse scraping with slag to the slag discharge mode. Scraping the mud scraper in the back of the mud scraper all up. When he returned to the starting position when scraping mud, mud scraping rake down, so the cycle of work

2, working principle

Scraping mud machine and walking motor running in their duties, non-interference, mud scraper bottom with water down the walk wheel structure, so as to ensure the running smoothly, two motor driving the synchronous motor, thus ensuring the walk on both sides of the smooth.

3, the main structure

The driving type mud scraper is mainly composed of a transmission device, a driven shaft device, a drive shaft device, an adjusting device, a bracket, an electric control box and other components.

(1) driving device is arranged on the walking wheel brackets, composed of asynchronous induction motor, cycloid pin wheel reducer, gear and machine. The transmission device has high transmission efficiency, large torque, stable running and low noise. A safety shear pin is arranged in the gear wheel of the output shaft of the speed reducer, thereby realizing the mechanical overload protection function. Motor deceleration device has enough output torque, rated torque is greater than the scraper scraping mud torque of 1.25 times, and set the scraper and a pool bottom up and down regulating mechanism, in order to control the distance to the scraper and the bottom of the pool, adjusting range is 0-50mm.

(2) after the installation of the transmission device does not make up and down adjustment, mainly by Qi transmission gear for transmission, the gear meshing clearance is compact and uniform noise free phenomenon.

(3) the scraping mud machine [and running motor in the operation of the requirements without mutual interference phenomenon, the operation of each other without interference.

6, characteristics

1, the peripheral inlet and outlet of the sedimentation tank is designed with the side section, which ensures the uniform distribution of water and the flow out of the periphery of the sedimentation tank.

2, the driving device adopts helical gear reducer and worm gear reducer combination to ensure the output torque and speed, high transmission effect; the speed reducer is equipped with over force torque protection device, safe and reliable operation;

3, when the diameter is less than or equal to 40m, with unilateral Straw, with >40m, with bilateral Straw;

4, the mud suction pipe to the level of the perforated pipe, density flow on pool does not produce without interference, to ensure the water stability.

5, the suction mud on the conical suction pipe on the unique design, the use of variable pitch, from the inside out, from small to large, to ensure that the bottom surface of the entire pool of mud suction, to improve the concentration of sludge, sludge return to save power;

6, there are two ways of skimming: plate skim and tubular skim;

7, the equipment is easy to operate, can be directly on the local / remote control equipment
