The sidewall belt conveyor is compact in structure, occupies a small area, runs reliably, can realize vertical lifting, is the ideal equipment for big along Angle delivery. In this paper, the drilling characteristics and application in the production of granular cotton are introduced in detail, and three improvement suggestions are put forward for the belt conveyer with the edge of the belt conveyor with the edge of the belt conveyor with the edge of the belt conveyor with the edge of the belt conveyor with the edge of the belt conveyor with the edge of the belt conveyor with the edge of the belt conveyor with the edge of the quilt: increasing the guiding mechanism to prevent the perspiring of the skin, optimizing the structure of the fuselage and the manufacturing process, so that the vibration cleaner can be manipulated.
Granular cotton is a kind of light, non-combustible and other characteristics of new building materials, its appearance is white, gray or light yellow floc granular: it is widely used in all kinds of buildings of fire prevention, insulation, sound absorption, such as: with granular cotton can do building wall insulation filling, steel structure building fire spraying, at the same time, granular cotton is all kinds of sound absorption board products of high quality raw materials. In industrial production, there are many kinds of conveying forms of granular cotton, which can be divided into pneumatic conveying and conveyor conveying. Because granular cotton contains a certain amount of slag ball. During pneumatic conveying, the inner wall of the air duct is impacted, so that the air duct gradually wears and penetrates. This phenomenon is especially obvious at the elbow of the air duct: For conveyor transportation, and can be divided into horizontal transportation and large dip Angle transportation (vertical transportation), large dip Angle transportation covers an area of small, at the same time reduce the number of mechanical equipment, splatted edge belt conveyor as a new type of lifting equipment, very suitable for granular cotton transportation. · Corrugable belt conveyor has the advantages of simple structure and reliable operation. It is not only compact in structure and covers less area, but also can realize vertical lifting, so it is an ideal equipment for large dip Angle conveying. It can be said that sidewall belt conveyor is a complex of belt conveyor and bucket elevator. The world has produced tens of thousands of sets of wavy edge belt elm conveyor, widely used in gold, building materials, chemical industry, food, coal, electric power and other sectors. From the early 1980s in our country began to produce sidewall belt conveyor and it has produced several thousand of them. In this paper, the characteristics of sidewall belt conveyor and bucket elevator will be compared by the application of sidewall belt conveyor in the grain cotton production line. The grain cotton production process is introduced as follows: raw materials (ore clean, coke, silica) by measuring and feeding system, is sent to the melting furnace to melt. A high speed fiber forming device is used to make the melt flow strands form fibers and cotton felt. The cotton felt is finally made into granular (i.e. granular cotton) by pelleting machine and rolling sieve. Then it is sent to two sets of baling machines for baling and packing. In order to weigh and pack granular cotton, it needs to be raised to a certain height. The other set of conveyor adopts the structural characteristics of sidewall belt conveyor 2.1sidewall belt conveyor. The structural characteristics of sidewall conveyor is to replace the ordinary conveyor with the sidewall conveyor (hereinafter referred to as the sidewall conveyor) : Its working principle and structure composition are similar to that of the belt conveyor. Therefore, the parts such as the tensioning device of the driving device, the middle frame, the middle leg, the tail frame, the transmission roll, the reversing drum, the roller, the unloading funnel, the air cleaner, the protection device can be used with the corresponding parts of the belt conveyor.
The main components are: guard belt roller and belt roller group, cleaner. 2.1.1 Retaining belt Figure 1 is a schematic diagram of retaining belt. It consists of three parts: baseband retaining edge and partition plate. The appearance of baseband is the same as that of ordinary conveyor belt, but it has greater lateral stiffness. The retaining edge is made into wave shape in order to enable the conveyor belt to bypass the rolling and convex, concave and isolated sections, in order to meet the requirements of the transmission line: the shape of the wave can be sine wave, square wave, W-shaped wave, etc. : on the base band between the two retaining edges, there are partitions set according to a certain distance: the partitions can be divided into T type, C type and T type according to their different sections.
2, 1.2 Press belt wheel and press belt lithium group Press belt wheel and press belt roll group have the same function, are pressed on the free side of the working face of the guard belt. Make the retaining belt change the running direction. You can choose one of the two. They are arranged at the return branch of the convex section and the bearing branch of the concave section of the retaining machine. Pressure belt wheel is the most commonly used form, consisting of a compound rim, shaft. The bearing seat is composed (in the form of press belt wheel in the pelletized cotton production line of Beixin Group). The large wheel rim is pressed on the empty edge of the guard belt, while the small wheel rim is gently pressed on the two guard edges. The press belt roller set consists of several cantilever rollers arranged according to a large, common radius of curvature: When the belt speed is large, it can effectively overcome the backward "winnowing" phenomenon when the material passes through the concave arc, but the belt roll produces large inertia force and torque, which is easy to make the material in the convex arc. 2.1.3 The non-working face of the retaining belt of the cleaner adopts the same air section cleaner as that of the general belt type coffin-feeding machine, while the working face is cleaned by vibration cleaner, which can be divided into two categories: dynamic and non-dynamic. The power cleaner uses a motor to drive the rotating roller through the belt pulley, so that the roller beats the non-working surface of the guard side belt and vibrates the materials adhering to it. An unpowered sweeper uses a guard strap to turn a ribbed roller. Make the guard belt vibrate up and down.
2.2 Application in Actual production In actual production, the packaging system is located in the workshop. The equipment layout is relatively compact, the site baler is very close to the conveyor. Moreover, the population height of the baler is relatively high, so the inclined belt cannot be used for conveying, and the vertical lifting scheme is considered.
The "lifting bucket" of sidewall belt conveyor is enclosed by a diaphragm and a guard, and there is no friction loss inside the material. The number of "bucket" per unit length is more than bucket elevator. The throughput is large. Due to the collision between the bucket elevator chain and the slide rail to produce a lot of noise, is not conducive to environmental protection, so the bucket elevator and took some sound insulation measures, so that the cost of the equipment itself. It can be seen that although the bucket elevator also has the characteristics of compact layout and large lifting height, but in the production of granular cotton, compared with the sidewall belt conveyor there are many defects, so it is recommended to use the wavy side conveyor in practical application as far as possible.
