Product display of leading companies in the water conservancy and hydropower industry
1. Product Introduction
The rotary grille decontamination machine is used at the water inlet of the sewage treatment plant and the water intake of the pumping station, as well as the front end of the grit chamber to block the water body Crop rhizomes, municipal solid waste, branches, aquatic plants and other debris in the water to protect the normal operation of the water pump and reduce the processing load of the subsequent processes of sewage treatment.
The width of the grille can be from to according to the flow rate of sewage treatment volume, and the gap between the grilles can be from to according to the requirements of dirt treatment.
2. Structural Principle
The rotary grating is generally composed of a driving mechanism, a chain transmission system, a dirt rake device, a frame, an overload protection mechanism, and an electronic control system.
Working Principle The driving mechanism drives the chain drive system to rotate. The tooth rake system drives the blocked dirt along the grid decontamination machine from bottom to top and lifts the dirt to the pool surface. After turning over, the dirt falls into the collection The device operates repeatedly to achieve solid-liquid separation.
3. Technical Features
The driving mechanism adopts a cycloidal pinwheel reducer, which has a large transmission ratio, high efficiency, resistance to impact loads, reliable operation and long service life.
The chain transmission mechanism adopts Asia-Pacific patented sealing technology to prevent dirt from blocking, winding and breaking the chain, ensuring stable transmission.
The roller has a novel structure, has two-way correction and reset functions, and can effectively prevent the chain from derailing.
The device adopts a unique tooth rake structure, which can remove large debris in the sewage and effectively prevent the sewage from falling back into the pool.
The protection is equipped with double protection of mechanical and electrical appliances, and is equipped with automatic control function, which can realize automatic operation without manual supervision.
Description of supporting products
The electrical control is usually manual control
The electronic control can be equipped with interfaces and can be linked with other equipment for time control and liquid level control. During the shutdown period, if the grille is accidentally blocked, When the water level in front of the grille reaches the set accident high water level, the decontamination machine can be started immediately without being restricted by the cycle. Special reminder can be used to control the liquid level difference. During the shutdown period, if the grille is accidentally blocked, the water level difference before and after the grille reaches the set level. When the value is set, the decontamination machine can work immediately. Users should indicate it when ordering if needed
Instructions for use of forward rotary grille decontamination machine
In order to ensure the normal operation of the equipment and personal safety, before installation and operation This manual should be read carefully. The equipment should be installed and operated by skilled personnel. The manufacturer does not assume any responsibility for accidents or liability caused by the participation of non-professionals. If you have any questions, please contact the company's local office immediately
Equipment Installation Debugging requirements
Before installing the crane, check whether the size of the foundation is consistent with the size of the machine base. After placing the foundation correctly, use steel expansion bolts to fix the equipment. Note: Before turning on the power, use the crank handle to enter the tail of the motor. Inside the square tenon, turn the motor by hand in the direction of rotation indicated by the arrow on the safety cover. There should be no other factors that affect the operation. Go to the safety cover to loosen the tensioned sprocket, remove the chain at the end of the reducer, and test the steering of the reducer with power on. Check whether the tensioning wheel and rake tooth chain are correctly adjusted. Check whether the lubricating oil of the reducer reaches the oil level. If it is insufficient, use mechanical oil to add it to the oil level. Regularly check the oil level. Turn on the power supply and the no-load operation is normal. After that, it is put into load operation. During operation, if there are fibrous debris blocking the rake tooth chain, it should be cleaned in time to avoid affecting the normal operation of the equipment. If the motor is running normally but the rake tooth chain is not running during operation, special reminders will be given. Overload causes the safety pin to cut off, and the overload safety pin must be replaced. The moving bearing should be lubricated with butter and should be refilled regularly
Installation, use and maintenance of the electric control box
The rated voltage for installation is, the grounding resistance is less than 1, and the grounding should be safe and reliable. Open the inner door of the electric control box and close the circuit breaker. Press the button on the door to control it as needed. Please note that when not in use, it is best to separate the circuit breaker and lock the door. The control box is an outdoor type, and the protection level is for special control requirements. Description of the drawings
During maintenance, check the electric control box to see if any contacts are loose. Dust should be removed. If water accidentally gets in, special reminders should stop using it, dry it in time, and have professional personnel perform maintenance and repairs
