Below, we introduce the function of the frame and protective cover for mechanical grates, hoping to provide you with more assistance.

The frame and housing cover of the mechanical grille are welded from stainless steel of appropriate dimensions, forming a rigid support structure. The housing and cover are continuously welded to prevent the leakage of waste water. The equipment frame is internally fitted with a traction chain circular motion guide track. The frame sides are made of stainless steel plates, forming the frame of the rotating mechanical grille, with sufficient cross-sectional dimensions to meet the working load requirements. The gap between the frame sides and the grille well is sealed with rubber plates on the frame sides to prevent waste.

Rotary Mechanical Grate Grating Bars

Mechanical gratings are used in the wastewater treatment of industries such as papermaking, slaughtering, leather processing, sugar production, winemaking, food processing, textile, dyeing, and petrochemicals, to remove suspended solids, floating materials, and sediments. Next up, our editor introduces the grating bars of mechanical gratings:

Grating bars are composed of parallel flat steel, made of stainless steel. The Chongqing rotary grating features tight upper and lower ends with a bar spacing of 20mm. The size of the grating frame corresponds to the width of the channel and is securely fastened with stainless steel bolts to the supports, with the bars mounted on the frame. The grating frame is firmly anchored to the concrete channel, and flexible baffles are used to block gaps between the frame and the channel wall to prevent wastewater from flowing past the grating. The flexible baffles are connected to the frame. Each grating bar has a rectangular cross-section shape. When the rake teeth mesh with the bars, there is a certain angle between the rake teeth and the bars in the vertical direction, to prevent the accumulation of smaller debris within the wastewater. The guide rails on both sides of the grating prevent debris from entering and affecting the operation of the cleaning machine.

1. Upon normal shutdown, the mechanical grate should be left in the correct position as per equipment specifications after the power is cut off. The rotary grate, buttons, and so on should be reset. Use high-pressure water to clean any debris left on various parts of the decontamination machine, and apply lubricant as required.

During the operation of the mechanical grate, if overloading occurs (due to encountering obstacles or tines that cannot be inserted), the hydraulic push rod should be actuated to open and close the guide rail. Repeat the operation to remove the obstacle, or in the event of other malfunctions causing the unit to stop, the automatic alarm system should automatically trigger an alarm or shut down the machine. Operators should immediately report to the site, cut off the power according to the fault condition, promptly rectify the issue, inspect relevant components, and if damaged, repair them in a timely manner.

3. The mechanical grate operates for at least half an hour daily, and lubricants of the specified type are added at the designated points in a timely and measured manner. Additionally, the surface paint of the unit must be kept intact without any debris left behind.
