The HG series rotary mechanical grille (grille cleaning machine) is a device that can continuously and automatically remove various shapes of debris from fluids, with the purpose of solid-liquid separation. It can be widely used in urban sewage, water supply industry, power plant inlet, as well as in the production processes of textile, food processing, papermaking, leather and other industries. It is currently the solid-liquid separation technology introduced in China

Product Introduction

The advantages of this are high degree of automation, high separation efficiency, low power consumption, no noise, good corrosion resistance, and can ensure continuous and stable operation without supervision. An overload protection device is installed, which will generate sound and light alarms and automatically shut down in the event of a malfunction, thus avoiding overloading work.

It could have adjusted the running interval according to user needs and achieved periodic operation; It can be automatically controlled based on the liquid level difference before and after the grille; And it has manual control function for easy maintenance. Users can choose freely according to different job needs.

Due to the reasonable design of the structure, it has strong self-cleaning ability during operation and will not cause blockage, so the daily maintenance workload is minimal.

The specifications are divided into HG300-1500 types according to the width and size of the machine. If the machine width exceeds 1500mm, it will be made into a parallel unit. The grid gap is divided into various specifications such as 1mm, 3mm, 5mm, 10mm, 20mm, 30mm, 40mm, 50mm, etc. The grid gap is selected based on the water flow rate, lifting height, total solid-liquid separation amount, and the shape and particle size of the separated material. Rake teeth made of materials such as ABS engineering plastic, nylon, and stainless steel can be selected according to user needs; The main frame is made of stainless steel material and carbon steel anti-corrosion material.

working principle
The HG series rotary grille is mainly composed of a driving device, a rake tooth mechanism, a cleaning mechanism, etc. It is assembled into a set of rotary grille chains by one type of rake tooth. Driven by the motor reducer, the rake chain rotates in the opposite direction of water flow.

When the rake chain rotates to the upper part, due to the guidance of the groove wheel and curved rail, relative self-cleaning motion occurs between each set of rake teeth, and the vast majority of solid material falls down by gravity. The other part relies on the reverse movement of the cleaner to clean up the debris stuck to the rake teeth.

Bar screenPurpose: The rotary grid cleaning machine (also known as the "solid-liquid separator") is widely used in urban sewage plants, water plants, pump stations, and power plant water inlets. It continuously and automatically intercepts and removes floating objects in the water to ensure the normal operation of the next process. It can also be used for solid-liquid separation in industries such as textile, printing and dyeing, slaughtering, leather, papermaking, brewing, sugar production, and food. This is a special shaped rake tooth made of ABS engineering plastic, nylon, or stainless steel, assembled in a certain arrangement on the rake tooth shaft to form a closed rake tooth chain, and its lower part is installed in the water body of the inlet channel. When the transmission system drives the sprocket to rotate uniformly and directionally, the entire rake chain moves from bottom to top, carrying solid debris and separating it from the liquid. The fluid flows through the gaps of the rake teeth, and the entire working state continues.

Due to the special structural shape of the rake teeth, when the rake tooth chain carries debris to the end of the turning motion, there is a relative self-cleaning motion between the front and rear rake teeth, which causes the debris to fall off by gravity.
Note: A rotating cleaning brush can be installed at the back to further remove the dirt trapped in the rake teeth. If a cleaning brush is required, it should be specified when ordering.

Electrical Control

The conventional method is manual control.
Electric control can be equipped with PLC interface; Can be linked with other entities; Can be time controlled; Liquid level control can be performed, and during shutdown periods, if the grille is accidentally blocked, causing the water level in front of the grille to reach the set accident high water level, the cleaning machine can immediately start without being limited by the cycle; It can control the liquid level difference. During the shutdown period, if the grille is accidentally blocked and the water level difference before and after the grille reaches the set value, the cleaning machine can immediately start working. Users should indicate their needs when placing an order.

Ordering instructions: When placing an order, the parameters marked with an asterisk in the upper right corner of the technical parameter table should be indicated; The main material to be specified (all carbon steel or all stainless steel or partially stainless steel);

2. Solid liquid separation of industrial wastewater from textile, printing and dyeing, slaughtering, leather and papermaking industries;
3. Solid liquid separation in sugar production, brewing, and food processing.

Key Features:
1. Compact structure, simple electrical control, easy to achieve automation;
2. Good corrosion resistance, low energy consumption, and low noise；

Working Principle:

It is a special shaped rake tooth made of nylon or stainless steel, assembled in a certain order on the rake tooth shaft to form a closed rake tooth chain, and its lower part is installed in the incoming canal water. When the transmission system drives the sprocket to rotate in a uniform direction, the entire rake chain moves from top to bottom and carries solid debris to separate from the liquid, while the fluid flows through the gaps in the rake teeth. The entire working state is continuous.
Due to the special structural shape of the rake teeth, when the rake teeth carry debris to the upper end and move in reverse, there is a relative self-cleaning motion between the front and rear rake teeth, which causes the debris to fall off by gravity. At the same time, a pair of rubber plate brushes are set at the back to ensure that each row of rake teeth can receive * cleaning effect when they move to that position.

According to the direction of water flow, the rake chain is similar to a grille, and the clearance between the rake teeth assembled on the rake chain shaft can be selected according to the usage conditions. When the rake teeth separate solid suspended solids in the fluid, it can ensure smooth flow of water. The entire work process can be continuous or intermittent.

The device'sThe advantages are high degree of automation, high separation efficiency, low power consumption, no noise, good corrosion resistance, and can ensure continuous and stable operation without supervision.

This device can adjust the operating interval of the device according to user needs, achieving periodic operation; It can automatically control the start and stop of the equipment based on the liquid level difference before and after the grille; And it has manual control function for easy maintenance. Users can choose freely according to different job needs.

Due to the reasonable structural design of the device, it has strong self-cleaning ability during operation and will not cause blockage, so the daily maintenance workload is minimal.
