Bucket Elevator with Explosion Safety Protection Device

Frankly speaking, it’s really necessary to install safety protection device on bucket elevator so as to ensure normal operation. Now, what is the significant inspection standard for equipment quality is that to minimize or completely eliminate all kinds of risks. According to structure of bucket elevator, there are many kinds of safety protection device. We can divide into the following protection devices based on their function: explosion safety protection device, running deviation safety protection device, overload, speed measurement and reversion protection device.
Here we will mainly introduce the explosion safety protection device. Because working components of bucket elevator and material running speed are relatively fast, also they are running in the sealing casing, if there are many dusts in materials, it will cause high dust contained. In the grain industry, materials always contain many flammable organic dusts, once dust content is too high, it maybe blast when meeting open-flame. Therefore, both design and application of bucket elevator must consider the explosion precaution.
Main measure: Please leave a dust mouth above the bucket elevator head drive. When conveying materials which will cause dust explosion, at this time please open the dust mouth, install dust collector and reduce dust concentration to make it have no necessary explosion conditions.

4 key factors decide the function of bucket elevator

 Bucket elevator can be installed singly or in a system, in order to meet the needs of the site and materials forms. The main parameter of the bucket elevator is according to the handling system, loading and unloading location conditions, production process and the characteristics of transported material,main aspects are as follows:
1. Conveying capacity: it means the amount per hour, usually calculated in weight or volume.
2. Conveying speed: improving the speed can increase the elevating capacity. Especially when use the belt bucket elevator for long distance transporting,it needs to improve the conveying speed, but if use chain bucket elevator you should not, in case of enlarging the burden.
3. Pats dimension: the dimension of parts include belt width, plate width, bucket volume, channel diameters and so on, these dimensions will have an impact on the conveying capacity.
4. Conveying distance: the total distance will have an impact on the total resistance and power.

5 Ways to Solve Bucket Elevator Ash Leakage

(1) Whole Casing flange gasket of bucket elevator damages or no flange gasket, please change new gasket, glue with the sealing glue, retighten the flange bolts.
(2) If material leaks from the head section and bottom base gap, please add a gasket or sealant.
(3) If altitude difference is too large, it will increase material feeding pressure, please change the material feeding method, add a feeding buffer device.
(4) Drive chain occurs idle rotation, please adjust the chain length. 

(5) Casing installation is not straight, please adjust perpendicularity of the casing length. 

Bucket elevator conveyor system equipment

Bucket elevator is one of the most commonly used lifting equipment with the advantages of high throughput, high lift height and smooth running.When using bucket elevator,the cooperation methods between bucket elevator and upstream equipment should be noticed,please see it as follows:
a.Hand feeding: the material in the bag can be fed into the conveying equipment through the feeding port. 
Advantage:The lifting machine can run normally without material blockage.
Disadvantage: Hand feeding required higher physical strength.

b. Feeding through Bin connected with chute: the feeding method saves human cost. Loading machine and vibration hopper are allowed under available working condition, hopper can store material and also brings buffer function, which will avoid overload problem because of too much material.

c. Common feeding and conveying equipment: belt conveyor, screw conveyor, scraper conveyor and so on.
In addition,if you do not know what equipment is suitable to cooperate with the bucket elevator,please feel free to contact our engineer,we will give you a best solution: http://www.pkmachinery.com/

►Introduction

Bucket elevator is designed to transport powder, granular and lump materials, which also can lift abrasive materials, such as fly ash, slag, limestone, cement slurry, cement clinker, cement, coal, dry clay, etc., it has an opening bin below for storing material, when the motor driving the endless plate chain (chain or belt) through the chute, the hopper fixed in the chain of plate (chain or belt) bring the material to the discharging opening, in this way it continuously convey the material.

Ring chain Bucket Elevator is applied in the vertical conveying of abrasive powder, granular and small lump materials, such as grain, coal, cement and crushed ore, etc., and its transportation height can reach to 40m. The bucket chains are characterized by simple structure, stable operation and hybrid or gravity discharge. The wheel rim uses combination sprocket, and it is easy to replace and has been specially treated to ensure a long service life. The underpart is equipped by gravity automatic tensioning device, so that it can maintain a constant tension to avoid slipping off the chain. The material temperature can not exceed 250 °C.
►Features
1. Ring chain bucket elevator with large capacity, high lifting height, running steady, long service life etc advantage;
2.Adopt wrought link chain as the traction components.
3.The outline dimension of cross section is little, installation arrange compact, save space;
4.High lifting height, with better sealing.
5.Customized capacity, height, material and surface treating etc processing technology.
►Advantage

    1. Excellent sealing, less environmental pollution.

    2. Easy Operation and maintenance, less wearing parts.

    3. Energy conservation and less maintenance ensure the machine a very low cost.

    4. Advanced design principle has ensured the reliability of machine operation.

    5. High accuracy. The housing case is of good rigidity and beautiful appearance by the edge folding and intermediate beading.

    6. Small size. Compared with other machines which have the same lifting capacity, size of this machine is smaller.

    7. Transmission capacity. The series hoist NE15 ~ NE800 a variety of specifications. Enhance the volume range of 15 to 800m3 / h.
 

►Working Principle
Hopper scoops up materials from the stone bucket below, then is lifted to the top with the conveyor belt or chain, and next it is downward rolled over bypass the wheel on the top and the materials are dumped into the accept slot now by bucket chain or hoist conveyor, and the whole process is over. The driving band of bucket elevator with driver is commonly made of rubber, and it is installed below or above the drive roller and the divert roller. The chain-drive bucket elevator is generally equipped with two parallel transmission chain, on which above or below is a drive sprocket and a divert sprocket. Continuous Chain or Belt Bucket Elevator for Cement are generally equipped with chassis to prevent the dust flying into the bucket elevator.

►Application
TH series bucket elevator is widely used for transporting material, the density is less than 1.5t/m3, easy to draw out powder, granular, block etc low grinding material. Round link chain bucket elevators are the preferred conveying systems for the transport of hot bulk materials and coarse-grained materials. Such as coal, cement, gravel, sand, fertilizer, grain etc.
►Selection condition
    1. What is the conveying material and its physical characteristics? such as bulk density, feeding size, temperature, mositure content etc.
    2. What is the processing capacity of the elevator?
    3. What is the lifting height of the elevator (distance between inlet and outlet)?
