2、Product Features:

2.1 Fewer transmission components, simple structure, integrated design, easy to maintain and manage.

2.2 Good corrosion resistance, energy-saving, and low noise.

2.3 ExcludingContinuous dirty action, clean slag removal, and high separation efficiency.

3. Construction and Operating Process:

3.1. The rotary grille cleaner is mainly composed of a reducer, frame, scraper chain, chain, and baffle.Control cabinets and other components.

3.2 Grilles are outdoor type, capable of normal operation in an environmental temperature range of -5 to 40°C, all componentsThe design ensures a long service life in harsh environments.

3.The 3 grates operate intermittently but can also run continuously for 24 hours if necessary.

3.The 4-tined chain consists of several groups of special-shaped tines made of stainless steel or nylon, assembled in a certain order on the tine shaft to form a closed tined chain, with the lower part installed in the water body of the inlet channel. As the drive system rotates the sprocket at a constant speed in a specific direction, the entire tined chain moves from top to bottom, separating solid debris from the liquid. The fluid passes through the gaps between the tines, with the entire working process continuously ongoing.

3.5 Due to the special structure and shape of the tines, it causes the tine chain to carry debris to the top and move in reverse.The relative self-cleaning motion between the front and rear rake teeth promotes debris to fall off due to gravity, while a pair of rubber brush plates are set at the back of the equipment to ensure that each row of rake teeth is thoroughly cleaned when they reach that position.

3.6 Grille supports are securely fastened to both sides of the concrete channel with base bolts, allowing for easy disassembly. GrilleThe grate installation ensures all wastewater in the channel passes through the格栅, with no dead zones and no accumulation of debris at the bottom.

   3.7-bar grille frame can withstand loads from large floating objects; the rated load of the teeth rake is ≥1000N, and inNo significant offset, damage, or deformation during operation with large water level differences.

3.8 grille equipped with mechanical overload protection device; generates an alarm inside the electrical control box upon overload, and automaticallyStart/Stop Machine.

3.The motor drive unit and grille guard are integrated as one, with the motor power supply at 380V, 3-phase, 50Hz.Ingress Protection (IP) rating:IP55, F Class Insulation.

3.10The stainless steel label is securely fastened in a prominent location on the equipment, featuring embossed numbers.Character MarkingAspiration.

Section 3: Equipment Installation and Commissioning Requirements

1. Check if the foundation dimensions match the base size prior to lifting and installation.

2. After verifying the basic dimensions, place the equipment into the foundation, ensuring the equipment's center aligns with the center of the grate channel. The deviation between the centers should not exceed 20mm.

3. Remove the safety cover and loosen the tensioning chain wheel. Remove the chain at the reducer end, then power on and test the reducer's direction to ensure it is correct.

Adjust the tension of the tensioner wheel and the gear rack.

5. After the unit operates normally under no-load with the power connected, then proceed to operate under load.

6. In operation, timely clean any obstructions such as fiber debris from the sprocket chain to prevent interference with the normal operation of the equipment.

7. If the motor operates normally but the gear rack does not, it indicates an overload has caused the safety pin to break. The overload safety pin must be replaced.

8. Lubricate rolling bearings with grease and regularly inspect for oil shortages. Inject grease into the oil nozzle on the bearing housing using a grease gun.

Four、Gearbox Maintenance

1. Lubrication Method:

Table of lubrication methods for helical bevel gear reducers in standard installation form: (see below table)

Note: When using grease for lubricating the reducer, it is recommended to use 2# lithium grease, 2# extreme pressure lithium grease, or 00# reducer grease.

2. The reducer must be lubricated before use. For ease of assembly and transportation, reducers upon shipment are generally not lubricated.

3. The reducers with oil lubrication are pre-filled with lubricating grease before shipment.

4. When the harmonic drive reducer operates under harsh working conditions, frequent start-stop cycles, and high or low temperatures, re-evaluate the lubricant should be considered.

5. When adding lubricating oil, the oil level should not exceed the upper limit of the oil gauge nor fall below the lower limit. During operation, it is essential to frequently check the oil level and promptly replenish with the same brand of lubricant. 

Helical Bevel Gearbox with Standard Installation Type, Oil and Grease Filling:

Note: The amount of oil for the reducer should be measured by the oil level indicator; the parameters in the table are for reference only.

6. Lubricant Replacement System:

DI once, replace after the first 300 hours of operation of the reducer. When replacing, remove any residual oil. Subsequent replacements: for those working continuously for over 10 hours a day, replace every 3 months; for those working less than 10 hours a day, replace every 6 hours.

7. Oil Replacement Schedule: Replace every 6 months.

8. Prior to restarting a reducer that has been unused for a long time, it is mandatory to replace the lubricating oil or grease.

9. No injection of unclean or corrosive lubricants is permitted.

5. Control Box Installation, Usage, and Maintenance

Installation and Usage Instructions:

Rated voltage is 380V, ground resistance less than 4Ω, grounding should be safe and reliable.

1. Turn on the electrical control, and close the circuit breaker inside the box.

2. Control by pressing the button on the box door as needed.

3. Do not use time-delayed circuit breakers and securely lock the box door.

4. This electric control box is an outdoor type with an IP55 protection rating.

Maintenance:

1. The electrical control box should be inspected regularly for loose contacts and dust should be removed.

2. If water accidentally enters, discontinue use and allow it to air dry or dry naturally.

3. Properly manage the electrical control box to prevent unauthorized access and damage.

4. Maintenance and repair should be performed by a qualified electrician.
