What are the selection techniques for sludge conveying screw conveyors

Sludge conveying screw conveyor; What are the selection techniques?

The sludge conveying screw conveyor relies on rotating spiral blades to transport materials, and different materials, output, and other conditions affect the selection of the sludge conveying screw conveyor. Sludge screw conveyor, also known as screw feeder and winch, has different names and functions in different regions and is used for conveying materials. The sludge conveying screw conveyor can also be used for conveying other materials, cement, coal powder, chemical particles, grains, etc.

Precautions for choosing a rotary conveyor:

Sludge conveying screw conveyor; There are numerous types, significant structural differences, and multiple design parameters that are interrelated and constrained, making design and selection complex and difficult.

1. Conveying capacity: The conveying capacity of a screw conveyor refers to the amount of material conveyed per unit time. When transporting bulk materials, calculate based on the mass or volume of the transported material; When transporting finished products, calculate the quantity of materials being transported. When matching vibrating screen equipment such as linear vibrating screen, rotary vibrating screen, vibrating screen, etc., the feeding amount of the vibrating screen should be calculated and the conveying amount should be controlled. Most conveyors need to consider whether they can be used in conjunction with other production equipment before design and production, in order to design the conveyor model reasonably.

2. Length and size: The length and size of the conveyor include the width of the spiral blade, the width of the Flat noodles, the volume of the hopper, the pipe diameter and the container size. The size of these components directly affects the conveying capacity of the screw conveyor.

3. Rotational speed: Increasing the conveying speed can improve the conveying capacity. When the conveyor belt is used as a traction component and the conveying length is large, the conveying speed becomes faster and faster. However, high-speed belt conveyors should pay attention to issues such as vibration, noise, starting, and braking. For conveyors with chains as traction components, the conveying speed should not be too high to prevent an increase in power load. At the same time, the conveying speed of the feeding machine should be determined according to the production process requirements.

4. Conveyor length and inclination angle: The length and inclination angle of the conveyor housing directly affect the total resistance and required power of the conveyor. At present, there are various types of conveyors, including direct parallel feeding and some with inclined angles. Therefore, when choosing a screw conveyor, these usage conditions should be explained.

5. Spiral conveyor motors can be selected from speed regulating motors and ordinary motors to control the conveying speed and capacity.

6. Whether the hopper is added to the feeding port and the size of the feeding hopper.

In addition, besides the sludge conveying screw conveyor, there are other factors that affect the yield. The viscosity and density of the material. The types and materials of spiral blades, solid spiral blades are mainly used for conveying dry, low viscosity small particles or powder materials; Spiral blades are mainly used for conveying blocks or materials with medium viscosity; The spiral surface of the blade is mainly used for conveying tough or compressed materials. The blade helical surface is mainly used for conveying tough or compressed materials.

The output also depends on the model. The tubular screw conveyor is prone to corrosion, with a sanitary length exceeding 13 meters and a pipe wall thickness of 10-15mm. High power motors are selected with an angle greater than 30 degrees. The conveying environment determines the length and connection method of the screw conveyor. When the conveying length is large, the thickness of the pipe wall of the screw conveyor should be 10-15mm, otherwise the screw conveyor is prone to breakage. When the angle of the screw conveyor is large, the motor with higher losses has higher power, and a high-power motor needs to be selected. The motors of screw conveyors include adjustable speed motors and general motors. The function of the motor is to control the transportation speed, so the requirements of the motor should also be clarified when choosing a screw conveyor.

Spiral Conveyor; Suspension bearings are a vulnerable component. In order to prevent materials from entering the bearing and reduce bearing wear, the bushing of the suspension bearing is usually made of iron or aluminum alloy. Meanwhile, the bearings are equipped with sealing and lubrication devices. Lubrication is usually achieved by squeezing grease into an oil cup and installing a sealing ring inside the bearing.

All right! What are the selection techniques for sludge conveying screw conveyors? I have already told you! I hope you can find suitable conveying equipment through the above points. Stainless steel screw conveyors require materials with high production requirements, such as pharmaceuticals, food and other industries, which have high demands for the sealing of the bearing chamber and the grinding degree of the spiral blades of stainless steel screw conveyors.
