In our country, the Steep Angle Conveyor is a new type of belt conveyor which was just developed. In foreign country: Germany, Britain, Japan, the former Soviet Union, the United States and so on it was researched and produced in early 1960s. It has produced and used about 40,000 machines in more than 90 countries in the world. The transmission Angle is large (090), the lifting height is high, the single machine is raised up to 200m: 2, a lot of savings are set up each covers an area, save the total investment of the project: 3. Energy consumption hemp, simple structure, less maintenance costs: 4. The material is not the most scattered, conveying powdery material is not easy to fly, the field of light fine auxiliary labor tolerance, reduce environmental pollution: 5. Compared with the belt conveyor of the same specification, the conveying capacity is large, and the conveying capacity is stable when it is used for large-collar Angle conveying. 6. From the level to the skew can be smooth over the quilt: 7. Tape brush enhancement, not easy to run off; 8. Low dryness of the whole machine: 9. Available models: (can be made into 1 type, S type, C type, L type, inverted L type, etc.) 10. Conveying material granularity: So it has been widely used in port, coal, mining, chemical industry, electric power, building materials, gold, light industry, grain, shipbuilding and other industries. In addition, steep angle conveyor can not only transport materials, but also rotate 180 degrees left and right to realize receiving or discharging within 360 degrees. These characteristics are very important in port bulk handling operations. Now combined with port machinery and technology.
This paper introduces the application examples at home and abroad and discusses briefly. 1. Application and discussion of ship unloading process: At present, the cargo receiving ship unloader at home and abroad can be divided into two categories: blow working ship unloader and continuous ship lifting machine. The snatch ship unloader is the main type of intertaking ship unloader, which is a traditional ship bending machine and widely used in ports and inland ports. However, the grab ship unloader has the following disadvantages: large energy consumption, dust pollution, strict noise, heavy, high wharf cost, heavy labor intensity of the driver, large clearance workload, difficult to realize the program operation. Continuous ship unloader mainly includes wavy guard belt type ship unloader (or double belt type), bucket wheel lead unloader, buried scraper ship unloader, chain bucket ship unloader, vertical blasting ship unloader, rope bucket ship unloader, pneumatic ship unloader and self-discharging ship, etc. Steep Angle Conveyor 1.1 Wave-guard belt type unloader (or double-belt type) This type of ship unloader used in port has rotating, tilting and wagon running mechanisms. The material is lifted vertically by the ship unloader from the ship gun and along the frame to the transfer funnel located in the center of rotation by steep angle conveyor or two self-forming loop belt conveyors (double-belt type). The grain unloader introduced by Dalian Port and Tianjin from Smcn-Carves of the UK is double-belt type, with a speed of 4.6m/s and a production efficiency of 600t. h. The material limiting device adopts the horizontal screw feeder. There are professional manufacturers of ship unloader with wave conveyor in foreign countries, such as the Portl type of wave conveyor made by China. The conveyor type is S shaped with a conveyor speed of 3m/s. The feeding load is a shallow bucket rotary drum set in the lower horizontal section of a steep angle conveyor. The designed production efficiency of this machine is 1000t.h(grain unloading) and 8501h(coal unloading). Examples abroad: for example, has installed the wavy guard belt type ship unloader for unloading coal and ore. Main parameters of belt conveyor with shaped guard: bandwidth: 1214mm; Belt speed 3.3m/s: Throughput: 2000mh. The main advantages of the wave-shaped guard type ship unloader are: stable operation, low noise, low energy consumption, low quantity in a variety of ship unloader, small environmental pollution, high efficiency, so it is urgent in our country, especially the specialized port application of the machine. As for small and medium-sized inland ports, it is not ideal to use the above model for small barge unloading ships. For ship types such as deck barge, the model can be quite simple. If the fixed machine shifting type is used (currently the world's inland rivers are mostly used this type), you can omit the track, cart running mechanism, and receiving belt conveyor. The productivity can reach hundreds to thousands of tons per hour. Its working principle: Steep Angle Conveyor the material loading limit will be fine into the shaped guard belt, lifted into the hopper, and then transported by the upper conveyor belt, the forward movement of the material can be completed by the luffing mechanism.
