Grille spiral conveyor

Our company produces and operates a wide variety of products, among which one of the main products is the grid screw conveyor, with the following specifications:

Grid screw conveyor is a device used to transport materials such as grid slag separated by grid cleaning machines, commonly used in industries such as sewage treatment. Here is a detailed introduction about it:

structural composition

It mainly consists of a driving device, head assembly, housing, shaftless spiral body, groove lining plate, feeding port, discharging port, etc. Drive devices often use cycloidal pinwheel reducers or shaft mounted hard toothed gear reducers; The shaftless spiral material is stainless steel or carbon steel; The groove lining plate is generally made of wear-resistant (based on actual reports) plastic plate, rubber plate or cast stone plate; The shell is U-shaped or O-shaped, and a rain cover can be added to the upper part. The material is stainless steel, carbon steel, or fiberglass.

working principle

The driving device transmits power to the shaftless spiral body through a coupling or chain, causing it to rotate stably on the lining. When the spiral rotates, the blade surface exerts a thrust on the material. Because there is no shaft, the material will not entangle. At the same time, under the combined action of its own gravity and spiral thrust, it moves forward along the bottom of the groove until it reaches the discharge port.

feature

Good anti winding performance: The shaftless structure solves the problem of blockage caused by the shaft in traditional screw conveyors, especially suitable for conveying easily entangled slag such as hair and fibers.

Good environmental protection performance: Adopting fully enclosed conveying and easy to clean spiral surface, it can protect environmental hygiene and prevent the conveyed materials from being contaminated or leaking, reducing the emission of odors.

High torque and low energy consumption: Due to the lack of a shaft in the spiral, the material is not easily blocked, and the discharge port will not be blocked. It can run at a lower speed, with smooth transmission and reduced energy consumption. The torque can reach 4000N/m.

Large conveying capacity: The conveying capacity is 1.5 times that of traditional shaft screw conveyors with the same diameter, and the single machine conveying length can reach 60 meters. Long distance conveying can be achieved through multi-stage series connection.

Application scenarios

Environmental protection industry: mainly used for conveying slag at the back end of fine grid cleaning machines in sewage treatment plants, as well as conveying sludge cake in the sludge dewatering section. It can also be used in garbage treatment plants to transport viscous substances in kitchen waste and household waste.

Chemical building materials industry: It can transport high viscosity materials such as resins, adhesives, asphalt, as well as chemical sludge such as desulfurization gypsum and fly ash. It can also be used to transport building materials such as cement raw materials, clinker powder, mineral sand, and white ash.

Food processing industry: suitable for the enclosed transportation of wet garbage such as fruit and vegetable waste, meat and bone residue, as well as the transportation of viscous food raw materials such as sauces and dough. Its stainless steel material meets food hygiene standards, and the spiral surface is easy to clean, which can prevent cross contamination.

We will strictly control every quality control and provide you with high-quality grid screw conveyor products and thoughtful services. Your trust and support are our driving force forward.
