Crushed Grating

Crushed Grate

Product Overview

The粉碎型格栅除污机is a purification equipment, an optimal solution to mitigate the harm caused by solid particles to environmental protection equipment, and a replacement product for traditional格栅除污机.

Traditional格栅cleaning machines are mostly semi-subterranean, using ordinary格栅cleaning machines to intercept and retrieve suspended and floating matter from wastewater. After the garbage is retrieved, it must be transported out through screw conveyor equipment or manual cleaning, which can cause secondary pollution to the surrounding environment. The construction and operation costs of pump stations are high, and there is a severe odor around the stations, especially in summer when there are many flies, mosquitoes, and pests, contributing to further environmental pollution.

This equipment employs specialized technology to crush medium to large solid particles in wastewater and sludge into fine particles of 8-10mm, which are then processed together with the wastewater in subsequent treatment stages. It eliminates the need for格栅渣滓 removal, creating favorable conditions for an underground, fully enclosed pump station design, saving on construction costs and beautifying the environment. It is applicable in municipal and hydraulic pump station systems; it can replace traditional gratings or be used in conjunction with them. Compared to traditional grating pump stations, the debris is crushed in the water, eliminating the need for waste disposal cleaning; it prevents odor leakage, protects the environment, significantly reduces land area requirements; installation and maintenance are simple, and underwater automatic coupling installation is achievable.

Model Description

Product Alias

Pulverizing Grating Screen Cleaner, also known as Pulverizing Grating or Crushing Grating Machine.

By installation method:

1. Channel-type crushing grating

2. Pipe-type crushing grate.

Working Principle

The粉碎型格栅除污机 consists of a submersible motor, gearbox, side panels, drive shaft, cutting blades, vertical drum, seals, mounting brackets, auxiliary grates, submersible cable, electrical control box, and standby manual grates. Once the motor starts, the blades and vertical drum rotate at different speeds simultaneously. Solid floating matter in the wastewater is intercepted and sent to the cutting area by the rotating grate as it enters the drum zone. The two blades rotating at different speeds quickly perform axial and radial cuts, reducing the matter into fine particles of 8-10mm. The finely crushed particles are then pumped out with the water, effectively preventing pump entanglement and blockage. The auxiliary grate assists in intercepting pollutants during high water levels.

Product Features

1. Integrated design, with a compact and aesthetically pleasing appearance.

2. Flexible structure and installation options, accommodating various channel sizes.

3. Operates at low speed with minimal wear rate and low power consumption. Utilizes a dual-axis differential principle for powerful and squeezing crushing.

4. Special structural design with strong self-cleaning capabilities; no entanglement or accumulation of debris.

5. Consistent head loss, ensuring stable water depth upstream and downstream.

6. A special transmission structure facilitates the replacement of wear items such as blades, simplifies maintenance, and reduces maintenance costs.

7. High-strength alloy or stainless steel blade disk ensures the high efficiency and reliability of the equipment operation.

8. Optimized design for high efficiency and low energy consumption.

9. A reliable protection system that automatically reverses and releases the load when the equipment is overloaded. If it fails to exclude the issue after three retries, the machine will shut down and an alarm will be triggered.

10. Amphibious motor, suitable for both land and water use. The motor operates normally both indoors and outdoors and can adapt to submersion when the water level suddenly rises.

11. Self-coupling installation for easy maintenance. The grid operates underground with an automatic coupling installation, eliminating the need for heavy lifting equipment. During maintenance, the equipment can be completely lifted out of the pool for inspection using lifting rings.

12. Low land occupation, minimal overall investment, fully underground equipment, compact in size, lightweight, no need for a pump house, and low civil engineering costs.

Low equipment investment cost; no need for auxiliary equipment such as screw conveyors, squeezing equipment, deodorization equipment, and waste disposal equipment.

Primary Application

1. For use in submersible pump stations, water intake networks, etc.

2. Used in conjunction with traditional gratings for waste management.

3. Used for sedimentation ponds, digestion ponds, and sludge dewatering systems.

4. Wastewater Collection System

5. Water intake project inlet filtration

6. Canal Entrance Project
