Conversion type mechanical grille

Zhengyuan Environmental Protection is a professional manufacturer of sewage treatment equipment. The supporting drum type grille machine adopts the new process flow of 2020, with direct selling prices from the manufacturer and one-stop customized production and installation services. It can continuously and automatically remove various shapes of impurities in the fluid to achieve solid-liquid separation. This drum type grille machine can also be widely used in water treatment projects in various industries such as textiles, printing and dyeing, food, aquatic products, papermaking, slaughtering, and leather making.

Conversion type mechanical grid, also known as fine grid filter or spiral grid machine, is a device that integrates fine grid cleaning machine, grid slag spiral elevator, and grid slag spiral press machine. It is an ideal equipment for separating floating, settling, and suspended substances in urban sewage treatment plants and industrial wastewater treatment processes. It is widely used for solid-liquid separation, filter residue cleaning, transportation, and press dewatering in urban domestic sewage plants and industrial wastewater treatment projects.

Conversion typeMechanical grille price:Starting from 7000 yuan, specific prices need to be consulted with customer service.

Working principle of rotary drum grille machine:

The drum type mechanical grille is made of grille plates that form a drum shaped basket according to the gap between the grids. The water to be treated flows in front of the basket, filters through the grille, and flows to the outlet of the water tank. The slag is trapped on the surface of the grille. When the water level difference inside and outside the grille reaches a certain value, the rotating toothed rake installed on the central shaft rotates back to clean the dirt. When the slag cleaning toothed rake collects the dirt to the top of the basket, it begins to unload the slag (the slag that can fall by its own weight is discharged into the slag groove); After each subsequent rotation of 159, the slag adhered to the rake teeth is automatically scraped off by the slag cleaning plate at the top of the basket and discharged into the slag groove. The slag is lifted by the spiral conveyor at the bottom of the groove, and after being pressed and dehydrated in the upper pressing section, it is unloaded onto the conveyor belt or transported outside the garbage truck. After being pressed and dehydrated, the solid content of the filter residue can reach 25% to 45%, which plays an important role in reducing transportation costs and preventing secondary pollution.

The control system implements fully automatic control, which can automatically start and stop according to time. If there is excessive torque, it will give an alarm in a timely manner and automatically stop the machine immediately. Carry out work without supervision.

Characteristics of rotary drum grille machine:

1. Simple structure, smooth operation, easy maintenance, and long lifespan.

2. High filtration capacity and efficiency, with a fiber recovery rate of over 80% for wastewater.

3. Small footprint, low cost, low-speed operation, automatic protection, easy installation.

4. Fully automatic continuous operation, no need for dedicated supervision, with a maximum filtered substance concentration of over 12%.

5. Can replace coarse filtration equipment such as mechanical grilles.

Selection of rotary drum grille machine:

The mechanical grid cleaning machine is customized according to the user's required water volume, as well as the width and depth of the civil canal, and the required rake tooth clearance. The equipment specifications are divided into XRD300-3600 types according to the machine width size. If the machine width exceeds 1800mm, it will be made into parallel units, with the middle part sharing the same wall panel. The clearance of the rake teeth is divided into 1mm, 3mm, 5mm, 10mm, 15mm, 20mm, 30mm, 40mm, 50mm and other required specifications. The selection is based on the amount of water, lifting height, total solid-liquid separation, and the shape and particle size of the separated material. Different materials are also selected. The depth of the equipment trench can be customized by the user according to their needs and actual usage situation. Generally not less than 0.8m and not more than 15m.
