I. Trapezoidal Dust Removal Frame

Definition and Structure

• Also known as trapezoidal frame or trapezoidal bag cage.
• Features a flat structure with evenly distributed longitudinal reinforcement and anti-support rings, providing sufficient strength.
• Smooth and straight surface, no burrs to prevent damage to filter bags.
• Characterized by uniform welding, rational structure, and durability.
• Lightweight structure facilitates easy installation and maintenance.

Quality Impact

• Directly affects the filtration status and service life of the filter bags.

Manufacturing Process

1. Wire Treatment
   • Steel drawing is used to enhance the strength and appearance quality.
   • Processes include silicone coating, galvanizing, and painting.
   • The coating is strong and corrosion-resistant, preventing rust and bag adhesion after a period of operation.
2. Welding and Grinding
   • Firm welding with a smooth profile.
   • Ensures the strength and appearance quality of the trapezoidal dust removal frame.

II. Spring Frame

Manufacturing and Specifications

• Made from spring steel wire with a diameter of 3mm, wound on a lathe.
• Generally 20 coils/m after stretching, with lengths of 1.5m, 2m, 2.5m, 3m, 4m, etc.
• Used in conjunction with dust bags.

Types

• Hook type, Venturi tube type, and another hook type.

Advantages

1. Flexible Design
   • Easy to transport, store, and maintain.
   • Ensures sufficient rotation and uniform tension.
2. Sturdy and Durable
   • Robust and reliable design structure, long service life.
3. Materials and Treatments
   • Materials: low carbon steel wire, galvanized steel wire, stainless steel wire.
   • Surface treatments: galvanizing, spraying, anti-corrosion, silicone coating, etc.
4. Application Areas
   • Widely used in metallurgy, building materials, power generation, chemical, food, waste incineration, and other industries.

Installation Method

Used on dust collectors with flower plate holes to save installation space.

The dust bag is placed over the outside, with the bottom twisted onto the hook of the spring frame.

The mouth is tied to the Venturi tube on the other side of the spring frame.
