2、Product Features:

2.1 Few transmission parts, simple structure, integrated design, easy for maintenance and management.

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

2.3 ExcludingContinuous dirty action, clean slag discharge, high separation efficiency.

3. Construction and Operation Process:

3.1. The rotary格栅cleaning machine 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 in intermittent cycles, but can also run continuously for 24 hours if necessary.

3.The 4-tined chain is composed of several groups of special-shaped tines made of stainless steel or nylon, assembled in a certain sequence on the tine shaft to form a closed tined chain, with the lower part installed in the water body of the inflow channel. As the transmission system drives the sprocket to rotate uniformly and in a fixed 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 unique structural shape of the teeth, the rake chain carries debris to the upper end and moves in reverse.The relative self-cleaning motion between the front and rear rake teeth promotes debris to fall off due to gravity. Additionally, a pair of rubber brush plates is set at the rear of the equipment to ensure that each row of rake teeth is thoroughly cleaned when they reach that position.

3.6 Grill support brackets are securely fastened with base bolts to both sides of the concrete channel, making them easy to dismantle. GrilleThe grate installation ensures that all wastewater in the channel flows through the格栅, eliminating dead zones and preventing garbage from accumulating at the bottom.

   3.7 Mesh Grill Frame can bear the load of large floating objects, with the rated load of toothed rake ≥ 1000N, inOperation under large water level differences results in no significant deviation, damage, or deformation.

3.8-grid configuration equipped with a mechanical overload protection device; an alarm is triggered inside the electrical control box upon overload, and it automaticallyPower on/off.

3.The motor drive unit integrates with the grille shield, powered by a 380V, 3-phase, 50Hz motor supply.Ingress Protection RatingIP55, F Class Insulation.

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

Section 3: Equipment Installation and Commissioning Requirements

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

2. After checking the basic dimensions, place the equipment into the foundation so that the equipment's center aligns with the center of the grille channel, ensuring the deviation between the two centers does not exceed 20mm.

3. Remove the safety cover, loosen the tensioned chain wheel, detach the reducer end chain, and power on to test the reducer's direction for correctness.

Adjust the tension of the tensioner wheel and gear rack.

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

6. During operation, if fiber debris or other obstructions block the toothed chain, they should be cleared promptly to prevent affecting the normal operation of the equipment.

7. If the motor runs normally but the toothed scraper does not, it indicates that an overload has caused the safety pin to break. The overload safety pin must be replaced.

8. Use lubricating grease for roller bearings and regularly check if the bearing is low on oil. Inject the grease into the oil nipple on the bearing housing using a grease gun.

Four、Gearbox Maintenance

1. Lubrication Method:

Table of lubrication methods for spur gear reducer with standard installation form (see below table):

Note: When the reducer is lubricated with grease, it is recommended to use No. 2 lithium-based grease, No. 2 extreme pressure lithium-based grease, or No. 00 reducer grease.

2. The reducer must be lubricated before use; for ease of assembly and transportation, reducers at the factory are generally not lubricated.

3. The gear reducer with oil lubrication has been pre-filled with grease before shipment.

4. In harsh working conditions for the worm gear reducer, such as frequent start-stop and exposure to high or low temperatures, reconsideration of the lubricant should be given.

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's essential to regularly monitor the oil level and promptly replenish with the same brand of lubricant. 

Standard installation form of cycloidal pinion reducer, oil and grease filling amount:

Note: The amount of lubricating oil for the reducer is determined by the oil level indicator; the parameters in the table are for reference only.

6. Lubricant Replacement System:

One-time DI replacement; after the first operation of the reducer for 300 hours, perform a DI replacement. During replacement, remove any remaining waste oil. For subsequent replacements, if the equipment operates continuously for more than 10 hours a day, replace every 3 months; if it operates for less than 10 hours a day, replace every 6 hours.

7. Oil Change System: Change every 6 months.

8. Before restarting a reducer that has not been used for a long time, it is mandatory to replace the lubricating oil or grease.

9. No injection of unclean or corrosive lubricating oil 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 secure the box door.

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

Maintenance:

1. Regular inspections of the electrical control box should be conducted for loose contacts and dust removal.

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 conducted by a qualified electrician.
