Product Overview
Pneumatic conveying tank is the most commonly used positive pressure conveying equipment with high cost performance ratio in pneumatic conveying systems. It is usually used in long-distance batch feeding systems. It is suitable for conveying various fragile, abrasive and non abrasive materials under the conditions of high pressure, long distance and high solid gas ratio. Such as quartz sand, plastic particles, etc. The whole conveying system is composed of pressure vessel (pressure tank), electric control system and conveying pipeline.
working principle
During the feeding process, materials are added into the sending tank through double butterfly valves or expansion butterfly valves, and the displaced air is released through the exhaust valve, which makes feeding easier and eliminates the reverse pressure that hinders the flow of materials. When the sending tank is full (90% of the tank volume is displayed by the level gauge), the feed valve and exhaust valve are closed and sealed at the same time, and then compressed air is added to the top of the sending tank through the air inlet valve. The added compressed air is mixed with the material. When the pressure in the tank reaches the set value, the bottom discharge valve is automatically opened. At this time, pressure is applied to the entire transmission pipeline, and then the material is transported in the form of a plunger, Until the material is drained. When the pressure in the sending tank drops to zero, the pneumatic supply is closed, and a small amount of remaining gas is also discharged from the sending tank and the transmission pipeline.
Product features
1. The conveying pressure is high, up to 0.5Mpa, to realize long-distance (100-300m) powder conveying.
2. Low flow rate, high solid gas ratio and low gas consumption.
3. The materials have high adaptability and versatility, and have little impact on the properties of the materials in the process, which can meet the requirements for the transportation of fragile and highly abrasive materials.
4. One point feeding to multiple points can be realized.
5. High ash gas ratio (mixing ratio): the length of the ash conveying pipe can reach more than 1:40-50 within 200 meters, and the air consumption is only 1/3-1/2 of the positive pressure dilute phase system or negative pressure system.
6. The working pressure is low (generally 0.1-0.2Mpa) and the flow rate is low: while improving the transmission efficiency, it effectively reduces the wear of the pipeline and reduces the consumption of compressed air.
7. High degree of automation: the system has high degree of automation, microcomputer control, simple operation, dynamic display of operating conditions, fault alarm, sensitive response, complete processing functions, remote operation and manual functions, flexible, convenient and reliable operation management.
8. The system operates reliably: the bin pump is small in size, light in weight, easy to install and maintain, and can be directly hung under the ash hopper of the dust remover or set up with feet.
The configuration of the system is flexible and convenient. The main moving parts and pipelines are matched. The valves, instruments and meters are standard parts, which are highly interchangeable and easy to operate and maintain.
