Rotary grid cleaning machine, reverse fishing rainwater interception equipmentPurpose:

The GSHZ rotary grid cleaning machine (also known as "mechanical grid, trash trap, slag extractor, solid-liquid separator") is widely used in urban sewage treatment plants, water plants, pump stations, and power plant inlets to automatically intercept and remove floating debris in the water, ensuring the normal operation of the next process; It can also be used for solid-liquid separation in textile, printing and dyeing, slaughtering, leather making, papermaking, sugar production, brewing, and food processing.

Rotary grid cleaning machine, reverse fishing rainwater interception equipmentKey Features:

Compact structure, simple electrical control, easy to achieve automation; Excellent corrosion resistance, low energy consumption, and low noise; The decontamination action is continuous, the discharge is clean, and the separation efficiency is high.

Working Principle:

This device is composed ofThe shaped rake teeth made of ABS engineering plastic, nylon or stainless steel are arranged in a certain order on the rake shaft to form a closed rake tooth chain, and the lower part is installed in the inlet canal water. When the transmission system drives the sprocket to rotate uniformly and directionally, the entire rake chain moves from top to bottom, carrying solid debris and separating it from the liquid. The fluid flows out through the clearance between the rake teeth, and the entire working state continues.

Due to the structural shape of the rake teeth, when the rake chain carries debris to the upper end and moves in reverse, a relative self-cleaning motion occurs between the front and rear rakes, which causes the debris to fall off by gravity,A rotating cleaning brush can be installed at the back of the equipment to further remove the dirt trapped in the rake teeth. If you need to place an order, please indicate it.

Technical parameters:

By device widthB grid machine is divided into single unit GSHZ300-1400 and parallel unit GSHZ1400-3000. Selection based on water flow rate and lifting height Depending on the size of the separated debris, different grilles can be selected accordingly.

Installation and Debugging

（1） Preparation before installation

Organize installation personnel to familiarize themselves with the equipment installation diagram, understand the structure, function, characteristics, and relevant technical requirements of the equipment.
A dedicated person should be responsible for unpacking the equipment. After unpacking, the equipment components should be checked for completeness and damage according to the packing list. If necessary, perform maintenance, cleaning, and oiling, then arrange neatly and cover with oilcloth or plastic cloth.
According to the requirements of the process layout diagram and the actual situation on site, check whether the equipment dimensions match the structure.

（2） Installation of equipment

Lift the whole machine into the canal, place it in the correct position, ensure the levelness of the main shaft, equal gap between the frame and both sides of the canal, and reliable sealing of the water seal rubber plate. Then, fix it to the foundation with expansion bolts or weld the frame pad to the foundation embedded steel plate.

（3） Debugging of equipment

Before starting up, the equipment should be thoroughly inspected and oiled. Check that all fasteners are not loose; Adjust the tightness of the transmission chain and rake tooth traction chain; Check the oil level of the gearbox. If there is no oil or insufficient oil, add lubricating oil.
Instantly start the motor and check if the rake teeth are running in the correct direction. The rake teeth run upwards in front of the grille (water inlet). After confirming that there are no abnormal phenomena (no shaking, no jamming, and no abnormal noise), the motor is officially started.
After 2-3 hours of no-load operation, if there are no abnormalities, water test can be carried out.
The rated voltage is 380V, the grounding resistance is less than 4 Ω, and the grounding should be safe and reliable.

6、 Operation and maintenance

During operation, if there are fibers or debris blocking the rake chain, they should be cleaned in a timely manner to avoid affecting the normal operation of the equipment.
If the motor runs normally but the rake chain does not operate during operation, it indicates that overload has caused the safety shear pin to cut off, and the overload safety pin needs to be replaced.
Add the same lubricating grease (2 # calcium based grease) to the rolling bearing once a week, and inject it from the oil nozzle on the bearing seat with a grease gun.
Regarding the maintenance and repair of the gearbox, follow the instruction manual for the gearbox.
