Product Overview of Large Tilt Angle Belt Conveyor (Edge Belt Conveyor):

　　The DJ large angle belt conveyor, also known as the edge blocking belt conveyor, has a structure in which rubber wave shaped vertical "skirts" that can be freely extended and retracted are glued on both sides of a parallel rubber conveyor belt. Between the skirts, there are horizontal partitions with certain strength and elasticity to form a box shaped hopper, allowing materials to be continuously transported in the hopper.

　　Large angle belt conveyors are widely used in coal, grain, building materials, chemical, hydropower, and metallurgical sectors. They transport various bulk materials with a specific gravity of 0.5-2.5t/m3 in the ambient temperature range of -19 ℃ to+40 ℃. For materials with special requirements for transportation, such as high temperature, materials with acidic, alkaline, oily substances or organic solvents, special edge blocking conveyor belts are required, so they are called edge blocking belt conveyors.

　　Characteristics and application scope of high inclination conveyor:

　　1. This series of products is a continuous conveying equipment for bulk materials, using a conveyor belt with wavy edges and horizontal partitions. Therefore, it is particularly suitable for high angle conveying.

　　2. Widely used in industries such as coal, grain, building materials, chemical, hydropower, and metallurgy, it can transport various bulk materials with a bulk density of 0.5-2.5t/m3 within an ambient temperature range of -19 ℃ to+40 ℃, and can also be called a grain conveyor.

　　3. The upper limit of the inclined angle conveyor is 90 °, and the upper limit of the particle size of the conveyed material is 300mm.

　　4. For materials with special requirements for transportation, such as high temperature or materials with acidic, alkaline, oily substances or organic solvents, special material corrugated edge conveyor belts should be used.

　　Large angle belt conveyor (edge belt conveyor) overall layout form:

　　To achieve better loading and unloading conditions, this machine adopts a "Z" - shaped layout. There are upper horizontal section, lower horizontal section and inclined section, and the material is received in the lower horizontal section and discharged in the upper horizontal section. A convex arc-shaped frame is used to connect the upper horizontal section and the inclined section, and a concave arc-shaped frame is used to connect the lower horizontal section and the inclined section to achieve a smooth transition of the conveyor belt.

　　1. Upper horizontal section: In order to meet the requirements of different unloading heights, the head frame is divided into a lower head frame (head frame height H0=1000mm), a middle head frame (head frame height H0=1100-1500mm), and a high head frame (head frame height H0=1600-2000mm). Correspondingly, the upper horizontal section is equipped with a low convex arc section frame and a low middle frame support leg (with a head frame height H0=1000mm), a Chinese convex arc section frame and a Chinese middle frame support leg (with a head frame height H0=1100-1500mm), and a high convex arc section frame and a high middle frame support leg (with a head frame height H0=1600-2000mm).

　　2. Tilt section: Regardless of whether the upper horizontal section uses low, medium, or high middle frame legs, the tilt section uses low middle frame legs. When the inclination angle of the conveyor is greater than or equal to 45 °, it is recommended to use Type II low middle frame support legs.

　　3. Lower horizontal section: The lower horizontal section adopts a low middle frame support leg.

Cleaning knowledge about swing screening machine - flat rotary screen
　　Swing screen, also known as swing vibrating screen, is a screening equipment that imitates manual screening actions. This series of equipment has good screening effect on cylindrical, elongated, and irregularly shaped materials without damaging the characteristics and shape of the materials themselves, meeting the requirements of modern people for screening materials: high efficiency and high precision. At present, swing screens are widely used in industries such as chemistry, food, medicine, and fertilizers.　　Do not stack any other debris around the swing screen machine, and the surrounding environment should also be kept clean. The price of the MSG swing screen should not be contaminated with other dust as much as possible to avoid the influence of other debris and prevent inaccurate screening of grains after screening. Before starting up and using the swing screen, it is necessary to check whether there are any debris in the machine compartment. The price of the glass bead swing screen should be cleaned to prevent different debris from mixing together and affecting the accurate screening of grains.　　Swing screens can be cleaned using bouncing balls, which is simple to use and easy to maintain. It is suitable for most granular materials, and ultrasonic cleaning is also a widely used cleaning method. It not only cleans the screen mesh, but also significantly improves production capacity. Suitable for most fine, high-yield, and difficult to screen materials, it improves work efficiency and time.　　Overall, China's swing vibration equipment is constantly improving and upgrading, and the market is showing a thriving trend. In the context of the continuous expansion of the food and drug market, domestic vibrating screen equipment should strengthen innovative technology, integrate market requirements, seize industry trends, and continuously meet the needs of more industries.

Internal factors causing noise in screening machines
　　1. Noise source　　The noise mainly comes from the operation of gears and rolling bearings. The main source of gear noise is gear collision caused by manufacturing errors such as smooth contact. The noise radiated through the shell to the connected structure also promotes the total sound power to be increased at resonance frequency, especially for large diameter gears, whose noise pollution is more serious.　　The noise of rolling bearings is often caused by the impact of the rolling elements in the raceway and the impact and vibration of the retainer inside the bearing. Therefore, it is related to the stiffness and smoothness of the vibrator shaft.　　2. Diffusion　　Resonance diffusion. Due to resonance between the frequency of the noise source and the vibration noise caused by the excitation of the screen, crossbeam, pipe, etc. In addition, resonance occurs when the natural frequency of the component is a multiple of the operating frequency of the sieve. It can be said that there must be resonance phenomenon in the center where strong noise is generated by the mechanical vibrating screen. Related to area. The diffusion noise is proportional to the area. From the characteristics of acoustics, it is difficult for low-frequency sounds to form noise without large-scale vibrations. Therefore, many inherent vibrations of large-scale vibrations are fundamentally in the low-frequency region. From this, it can be seen that there is a relative relationship between the area of the vibrating body and the generation of noise. The sieve, as a vibrating body, generates low-frequency noise due to the large-scale vibration of components such as the sieve plate and frame.　　3. Connect　　Poor connection (looseness) can cause impact, such as the screen frame and screen mesh colliding and the screen body components becoming loose. Due to rigid connections, there is significant noise.
