Granulated wood is a kind of light, non-combustible and other characteristics of the new building materials, its appearance is white. For example, granulated wood can be used for insulation filler for building walls, fire retardant coating for steel structure buildings. At the same time, granulated wood is a high-quality raw material for all kinds of sound-absorbing board products. In industrial production, there are a variety of transportation forms of granulated wood, which can be divided into air supported conveying and conveyor conveying. For conveyor conveying, it can be divided into horizontal conveying and large inclination conveying.
Corrugated sidewall betl conveyor is a kind of conveying equipment with small area and low investment of mechanical equipment.
As a new type of lifting equipment, the corrugated sidewall belt conveyor is very suitable for conveying granulated wood. Corrugated sidewall belt conveyor has the advantages of simple structure and reliable operation, not only compact structure, occupying less land, and can achieve vertical lifting surface. Corrugated sidewall belt conveyor is widely used in metallurgy, building materials, chemical industry, grain, coal, electric power and other sectors. In this paper, the characteristics of the corrugated sidewall belt conveyor and the bucket elevator are compared through the application in the production line of granulated wood.
The production process of ranulated wood it that: raw materials (slag, coke, silica) by measuring and feeding system. These was sent to the melting furnace in melting. Using high-speed fibre device makes the melt flows to form a fiber and a cotton blanket. Cotton blanket entire to the pelleting machine, trommel screen that made of granular (namely granulated wood), and then sent to package. In order to weigh and package the granulated wood and lift it to a certain height, the granulated cotton packaging system of beixin group adopts a bucket elevator in one set and a wavy side guard belt conveyor in the other.
The structural characteristics of the corrugated sidewall belt conveyor
The structural characteristic of the
corrugated sidewall belt conveyor is to replace the common conveyor belt with the undulatory retaining belt conveyor. Its working principle and structure are similar to the ordinary belt conveyor. Therefore, parts such as drive device, tensioning device, intermediate frame, intermediate leg, tail frame, transmission pulley, reversing roller, idler, empty section sweeper, protection device and other spare parts are can be used with the corresponding parts of the belt conveyor.
Installing guide device to prevent belt deviation
In the production practice, the traditional corrugated sidewall conveyor belt is easy to wear and tear and the base belt is easy to tear. These are because the friction between the belt and the belt roller or the base belt, which reduces the service life of the belt. Therefore, solving this problem can greatly reduce the cost of users, reduce the time spent on repairing or replacing belts, and improve production efficiency. The main reason for the failure is that the traditional sidewall belt conveyor frame adopts welding structure, and the installation accuracy is difficult to meet the design requirements. There are guard and baffle on the belt that can not install self-aligning roller so the belt deviation is large.
Improving the structure and manufacting process
The main structure of the corrugated sidewall belt conveyor is generally channel steel welding parts. The overall quality of the equipment depends on the technical level and installation conditions. In addition, due to the poor overall rigidity of stinger steel structure equipment, it is necessary to add special plover frame and auxiliary support frame to improve the rigidity of the whole machine, resulting in complex equipment structure, long installation cycle and high cost. Therefore, it is necessary to improve the fuselage structure.
After improvement, the whole fuselage is a web structure with overall bending of steel plate. Bolt connection is adopted instead of welding to ensure the rigidity of the whole frame without honing frame and auxiliary support frame.The mounting hole adopts the paired and combined drilling process to ensure the mounting accuracy. The support square steel adopts post-welding iron cutting and combined drilling to eliminate welding cross shape and achieve the best parallelism between the supporting rollers. The frame of
corrugated sidewall belt conveyor is connected with the connecting plate by bolts, which not only avoids welding distortion, but also can be installed quickly. In addition, it is easy to add a dust proof floor to the bracket wall plate for the steel plate bending to improve the working environment.
Control the vibrating sweeper
When the conveying material is not attached, the flap roller can be manipulated to raise its center without contact with the sidewall belt. At this point, as the flap roller is no longer rotating and reduce the rotation of sidewall belt conveyor.
