The difference between large dip Angle conveyor and bucket elevator

The belt conveyor takes the conveyor belt as the traction force and bearing member, and carries out the material conveying through the movement of the conveying belt bearing the material. Belt conveyors can form complex assembly lines with other conveying equipment. The choice of drum is very important in the design of belt conveyor. The main index of choosing drum is the diameter of drum. Let's take a look at the belt conveyor drum diameter selection method.
1. The maximum or average specific pressure between the conveyor belt and the roller surface.
2, coating and coating deformation.
3. The allowable strength utilization rate of the conveyor belt (that is,  the percentage of the maximum tension of the conveyor belt to the allowable tension of the conveyor belt).
4. The bending frequency of the conveyor belt (related to the winding method, the number of rollers bypassed,  the distance and the speed).
5, the installation site and service conditions of the conveyor (such as: ground, underground, open air, mobile, fixed, etc.)
6. Bending stress of conveyor belt when it bypasses the drum.
The above method is the belt conveyor drum diameter selection method.

There are three main situations of belt conveyor noise: the noise of belt conveyor idler with serious eccentricity, the noise of belt conveyor coupling two axes with different centers, and the abnormal noise of belt conveyor reversing drum and driving drum. The following are the causes and solutions of these three situations to do a specific analysis:
First, belt conveyor roller serious eccentric noise
Abnormal noise and periodic vibration often occur to idlers during the operation of belt conveyors. Especially the return roller, because of its large length, since the weight, noise is relatively large. Noise has two main causes.
1. The wall thickness of the seamless steel pipe used for manufacturing idlers is uneven, resulting in greater centrifugal force. 2. When machining, the deviation between the center of the bearing holes at both ends and the center of the outer circle is large, so that the centrifugal force is too large.
Solution: It can continue to be used under the condition that the bearing is not damaged and noise is allowed.
Two, belt conveyor coupling two axes of different centers of noise
Abnormal noise from the coupling between the motor at the high speed end of the drive and the reducer or the coupling with the brake wheel, This noise is also accompanied by vibrations at the same frequency as the motor turns.
Solution: The position of the motor reducer should be adjusted in time to avoid the fracture of the input shaft of the reducer. 3. Abnormal noise of belt conveyor reversing drum and driving drum
The noise is very small when the reversing cylinder and the driving cylinder work normally. When the abnormal noise occurs, the bearing is generally damaged and the bearing seat makes a rattling sound.
Solution: Replace the bearing.

The conveyor belt of the strong belt conveyor is composed of multiple steel ropes instead of the canvas layer (or other materials) of the common conveyor belt as the core body, so the conveyor belt has high tensile strength.
Difference: Compared with the general belt conveyor, the main feature of the strong belt conveyor is the different structure of the conveyor belt. The conveyor belt of the strong belt conveyor is composed of multiple steel ropes instead of the canvas layer (or other materials) of the common conveyor belt as the core body, so the conveyor belt has high tensile strength. This kind of conveyer can realize single long-distance transport without reprinting, simplify the transport system, improve the transport efficiency.
Technical characteristics: The main technical characteristic parameters of strong belt conveyor are product specifications, conveyor capacity (t/h), conveyor length (m), conveying material type, conveyor belt width (mm), belt strength (N/mm), belt speed (m/s), conveyor belt steel rope core diameter (mm), number of roots, motor model, rated power (kW), rated voltage, reducer specification type Number, brake specifications, brake torque, etc.
Working principle: When the powerful belt conveyor works, the motor rotates through the reducer and coupling to convert the electric energy into the working torque of the driving drum. The movement between the driving drum and the conveyor belt depends on the friction force to drive the conveyor belt. The cargo moves with the conveyor belt on the conveyor belt. The strong belt conveyor generally uses the upper belt to transport the cargo, and it is unloaded at the end. The special unloading device can also be unloaded in the middle.
Specification type: The strong belt conveyor in our coal system use a lot, especially in recent ten years develop very fast. At present, although the strong belt conveyor is not shaped products, but the product series has been standardized.
At present, the strong belt conveyor produced in our country has 7 kinds of bandwidths, 5 kinds of belt speeds and 10 kinds of belt strength, which can form 51 kinds of different specifications of products to choose.
The bearing section and return section of the conveyor belt are supported on the frame idlers to reduce the running resistance of the conveyor belt. And the tension device provides the required tension force for the normal operation of the conveyor belt.
Compared with the general belt conveyor, the strong belt conveyor has the following characteristics:
(1) The conveyor belt of the general belt conveyor uses canvas, polyester, nylon and other fibers as the core layer of the conveyor belt; The conveyor belt of the strong belt conveyor is made of many fine steel ropes as the core layer material.
(2) Due to the limitation of the strength of the conveyor belt, the current maximum length of the general belt conveyor is generally l000 m; The conveyor belt of the strong belt conveyor adopts the silk rope as the core layer, greatly improving the strength of the conveyor belt, and the transport distance can reach 15,000 m.
(3) the general belt conveyor has shaped products, users only need to choose according to the conditions of use; Strong belt conveyor has not been finalized design products, the user needs to put forward conditions, to choose standardized design products.

The high dip Angle wavy guard conveyor belt is composed of three parts: base belt, guard edge and diaphragm. The retaining edge is used to prevent the material from slipping and scattering. In order to facilitate the bypass of the drum, the stop edge is designed to be corrugated; The role of the diaphragm is to support the material, in order to achieve large dip Angle transportation, the use of T type TC type. The baffle and the baffle are connected to the baseband by secondary vulcanization method, which has a high connection strength.
Product features:
1, increase the transmission Angle (30~90 degrees);
2, small area, less investment;
3, large throughput, higher lifting height;
4. Transition from horizontal to inclined (or vertical);
5. It is suitable for conveying powdery, granular, small block, pasty and liquid materials that are easy to scatter;
6, low energy consumption, simple structure, high belt strength, long service life.
Wavy guard conveyor belt (ordinary large dip Angle wavy guard conveyor belt) varieties:
According to the different properties of the covering adhesive, the wavy retaining conveyor belt is divided into ordinary type, heat resistant type, flame resistant type, cold resistant type, acid and alkali resistant type, oil resistant type, etc.
