product description

I. Overview:

主要用于轮船或火车等散装粉体物料的转移,如水泥、粉煤灰、矿粉等散装物料的转移入库或直接装入罐装车运送到使用现场。 Negative pressure suction machine is mainly used for the transfer of bulk powder materials such as ships or trains, such as cement, fly ash, slag powder and other bulk materials.
按承载工具分为:固定式、移动式(导轨式、车载式)、船载式。 Qunsheng (QS type) bulk material negative pressure suction machine is divided into fixed type, mobile type (rail type, vehicle type), and ship type according to the load tool. Which one is used depends on the actual situation on site and user requirements.
后,后续送料方式有:机械输送、正压气力输送、直接装车式。 After the negative pressure suction machine , the subsequent feeding methods are: mechanical conveying, positive pressure pneumatic conveying, direct loading.
1. Direct loading type:
Roots vacuum pump is used as the power of suction, and the materials are sucked from the bulk warehouse to the separator through the suction nozzle and the hydraulic suction arm. The separated material is discharged to the bulk tank or screw conveyor into the material tank of the transporter through the discharge valve. The clean air separated from the material passes through the exhaust pipe from the upper part of the separator, enters the Roots vacuum pump, and then comes from Roots. The air outlet of the vacuum pump is exhausted to the atmosphere.
Direct loading material process:
Bulk Cargo Warehouse— → Suction Nozzle— → Feed Pipe— → Separator— → Unloader— → Bulk Machine (Screw Conveyor) — → Transport Tank Truck
2. Mechanical conveying:
This system uses the Roots vacuum pump as the power of suction. The cement is sucked from the bulk warehouse to the separator through the hydraulic suction arm and the nozzle. Then, a series of processes such as natural settlement, cyclone separation, and bag filtration are used to separate the cement and air. Separation. The separated cement passes the discharge gate valve and the transition bin, enters the gasification chute, and then conveys the cement to the top of the silo through a bucket elevator. Finally, the cement is transported to the gasification chute through the gasification chute arranged on the top of the silo. In multiple silos, the detailed process is shown in the system diagram.
The clean air separated from the material passes through the exhaust pipe from the upper part of the separator, enters the Roots vacuum pump, and is discharged to the atmosphere from the air outlet of the Roots vacuum pump.
Mechanical conveying material flow:
Bulk cargo warehouse— → Nozzle, material tube— → Separator— → Transition warehouse— → Gasification chute— → Bucket elevator— → Warehouse top gasification chute— → Silo— → Bulk machine— → Transport tanker
3. Pneumatic conveying:
This system uses a Roots vacuum pump as the power of suction. The hydraulic suction arm and suction head suck the cement from the bulk cargo warehouse to the separator, and then adopt a series of processes such as natural settlement, cyclone separation, and bag filtration to separate the cement and air. After separation, the separated cement passes through the three-way valve and enters the warehouse pump ①. When the warehouse pump ① is full, the level meter alarms. The three-way valve switches the direction and the cement starts to enter the warehouse pump ②. At the same time, the warehouse pump ① The pressure valve, fluidization valve and discharge valve are opened, and the pressurized feeding is started. The cement is transferred to one or more silos through the switching of the pipeline and the top valve of the storehouse. After the silo pump ① is empty, the silo pump ② When the material is full, the three-way valve is switched, and the warehouse pump ① starts to feed again, and the warehouse pump ② starts to feed. In this way, the two warehouse pumps are rotated and sucked and fed. The clean air separated from the material passes through the upper part of the separator. The air duct enters the Roots vacuum pump, and is discharged to the atmosphere from the air outlet of the Roots vacuum pump.
Pneumatic conveying material flow:
Bulk cargo warehouse— → Nozzle and material pipe— → Separator— → Silo pump 2— → Silo pump 1— → Silo— → Transport tanker— → Bulk machine
Working principle:
利用罗茨鼓风机(真空泵)产生负压,通过吸嘴,将物料与一定量的空气混合后经过吸臂上的输料管送到分离装置内。 Qunsheng bulk material negative pressure suction machine uses Roots blower (vacuum pump) to generate negative pressure. Through the suction nozzle, the material is mixed with a certain amount of air and then sent to the separation device through the feeding pipe on the suction arm. After the material is separated from the air, it falls and enters the conveying machinery or enters the positive pressure conveying equipment. The positive pressure generated by the air compressor passes the feeding pipeline to send the material into the bulk material warehouse (warehouse). The clean air is discharged from the upper part of the separator through the exhaust duct, and is discharged into the atmosphere from the roots of the Roots blower (vacuum pump).
Equipment advantages:
1. It can suck and discharge at multiple points, and the equipment and pipes can be flexibly arranged to save space. The main equipment can be set in the open air.
2. The equipment structure is simple and compact, with few mechanical transmission parts and few wearing parts.
3. As it is transported in a closed pipeline, it can well control the dust out, and the dustproof effect is good. Conducive to environmental protection and improved working conditions.
4. Easy operation, management and maintenance.
5. The degree of automation of the equipment control and the reliability of the electrical appliances have reached the international level of the same industry.
6, can improve labor conditions, improve efficiency, and achieve automation
7, no material scattered, bilge materials are unloaded clean
8, high production efficiency, not affected by climatic conditions
9, the material will not be polluted
