Bulk cement machine is a special equipment for bulk cement. It connects the cement silo with the bulk cement transportation tools, and realizes the automatic or semi-automatic transportation of bulk cement through the interlocking action of a series of control devices. According to different unloading methods, it can be divided into bottom bulk cement machine and side bulk cement machine. According to the different modes of transportation, it can be divided into automobile cement bulk machine, train cement bulk machine and marine cement bulk machine.
First, the main equipment of cement bulk machine
1 model, ZSQ- 150ⅱ bulk cement machine;
① ZSQ-150 Ⅱ cement bulk machine is installed on the side of cement silo, which is a special equipment for automobile bulk. It consists of an inflation box, a one-way spiral gate, an electric rotary valve, a connecting chute, a telescopic loader, a material level gauge, a Roots blower or a high-pressure air source, a high-pressure centrifugal blower, a winch driving device, a dust collector and a control system. Use Roots blower or high-pressure air source to fluidize and inflate the cement in the silo, and use high-pressure centrifugal blower to inflate the connecting chute, so as to ensure the chute to discharge quickly. The working principle of bulk loading and unloading is the same as that of ZSQ- 150I bulk cement machine at the bottom of the reservoir.
② Technical parameters of ZSQ-150 Ⅱ bulk cement machine at the reservoir side.
▲ Loading capacity: 150 tons/hour
▲ Lifting adjustment range of loading head: 0 ~ 1 100 mm (it can be increased as required).
▲ Vertical speed of loading head: 0.2 1m/s
▲ Working pressure of micro-pressure level gauge: 7000Pa.
▲ Wind pressure of chute fan: 3.5× 10? protactinium
▲ Exhaust air pressure of bellows in the warehouse: 3× 10? (a=5) Pa
▲ Dust collector treatment air volume: 1200 ~ 1800 m? /h
▲ Dust gas emission ≤8.4m? /minute
▲ Total installed power: 8.26Kw (including 3Kw Roots blower, 2.2Kw dust-collecting blower and 0.25Kw dust-collecting rapping motor).
2. ZSH cement bulk machine:
① ▲ ZSH cement bulk loader is a special equipment for bulk loading and unloading of cement trains, which is mainly composed of casing, hopper, loading head, driving device, lifting device, fan, material level indicating system and electrical control system.
▲ The whole machine has the characteristics of compact structure, large loading capacity, long moving distance, PC program control and simple operation.
▲ When the bulk machine is working, cement or similar materials are sent to the bulk machine through the fixed feed hopper. Because the jacket adopts double-sided chute structure, the left and right lower jackets and the breathable layer form an inflation system. Between the feed hopper and the shell, the pressure belt on the upper shell passes through the feed hopper and covers the shell, sealing the feed hopper and the shell. The material can reach the discharge port in the middle of the shell through the feed hopper and the shell, and be loaded into the tank car through the hose in the charging head. The dusty gas discharged from the tank car is discharged into the system dust collector through the hose outside the loading head and the space above the chute.
▲ The movement of the bulk loader and the lifting of the loading head are completed by the driving mechanism and the small winch respectively, and the air source of the double-sided chute and the material level indicating system is provided by the same fan. When the material is full, the material full indicator signals to stop unloading.
