Background
In non-ferrous metal smelting or high temperature chemical engineering, powder materials such as smoke dust, powder or fine solid particles and the like are generated, and the powder materials need to be conveyed and enter the next working procedure. Currently, the main conveying methods of powder substances are: vehicle transportation, scraper blade transportation, auger delivery, belt transportation, gaseous transport specifically as follows:
1. vehicle transportation: the method is characterized in that powder substances such as smoke dust, powder, fine solid particles and the like are loaded into special containers of vehicles such as automobiles, trains, tank trucks and the like, and the powder substances are transported to a destination through transportation of the automobiles, trains and tank trucks; the vehicle transportation has the advantages of flexibility, convenience, close or far distance, more or less quantity and the like, and is particularly suitable for long-distance transportation; however, vehicle transportation is usually performed discontinuously, loading and unloading are required, the working efficiency is low, the labor intensity is high, the working floor area is wide, the field environment is poor, the material loss is high, and the defects are more obvious when the device is particularly applied to short-distance transportation.
2. Carrying out scraper plate transportation: the method comprises the following steps of enabling powder substances such as smoke dust, powder, fine solid particles and the like to enter a scraper conveyor through natural height difference, and then transporting the powder substances to a destination through the transportation of the scraper conveyor; the scraper plate transportation has the advantages of continuous work, high transportation efficiency, low equipment failure, less material loss and the like, and is suitable for medium-distance transportation; but the investment of scraper transportation is large, the occupied area of equipment is large, the power consumption is large, the field noise is large, and the scraper transportation is not suitable for short-distance transportation and long-distance transportation.
3. Carrying out spiral conveying: powder substances such as smoke dust, powder, fine solid particles and the like enter a spiral conveyer through natural height difference and the like, and then the powder substances are conveyed to a destination through the conveyance of the spiral conveyer; the spiral transportation has the advantages of continuous work, low equipment failure, less material loss, good working environment and the like, and is suitable for short-distance transportation; but screw transport is not suitable for medium and long distance transportation.
4. Belt transportation: the method comprises the steps of enabling powder materials such as smoke dust, powder and fine solid particles to enter a belt conveyor through natural height difference, and transporting the powder to a destination through the transportation of the belt conveyor; the belt transportation has the advantages of continuous work, high transportation efficiency, low equipment failure, low power consumption and the like, and is suitable for short-distance and medium-distance transportation; but the belt transportation investment is large, the equipment occupies a large area, the powder flying loss is large, the field environment is poor, and the belt is not suitable for long-distance transportation.
5. Gas transportation: the method comprises the steps of dispersing powder substances such as smoke dust, powder, fine solid particles and the like into flowing gas through corresponding facilities, and then transporting the powder substances to a destination through high-speed flowing of the gas in a pipeline; the commonly used gas is air, and nitrogen, carbon dioxide and other gases are used in certain fields; the gas transportation has the advantages of continuous work, high transportation efficiency, small occupied area, low energy consumption, less material loss, good field environment and the like, and is suitable for medium and long distance transportation; however, the failure rate of gas transportation is high, frequent failures include pipeline blockage, pipeline wearing and the like, and the gas transportation device is not suitable for conveying powder substances with high viscosity and high humidity.
Further, there are two types of conveyance, positive pressure conveyance and negative pressure conveyance, depending on the gas conveyance system. During positive pressure conveying, gas in the conveying pipeline is in a positive pressure state, and an air compressor is adopted to provide compressed gas at the front end of the pipeline; when the pipeline is conveyed under negative pressure, the gas in the conveying pipeline is in a negative pressure state, and vacuum pumping force is provided at the rear end of the pipeline by adopting vacuum equipment such as a water circulation vacuum pump, a rotary vane vacuum pump and the like; in contrast, the positive pressure conveying has stronger adaptability to materials and larger conveying capacity; the negative pressure conveying environment is better, and the loss caused by powder flying does not exist.
In the case of positive-pressure gas delivery, a subdivision is made into steady-state gas delivery and pulsed gas delivery. When the stable gas is conveyed, the supply of the compressed air is stable, the pressure is stable, and the flow is stable; when the pulse gas is conveyed, the supply of the compressed air in the conveying pipeline is unstable and constantly changes along with time, the pressure and the flow rate can also change, and the compressed gas flows to the conveying pipeline in a pulse mode in a 'one shot' manner; in contrast, the power consumed by steady-state gas transportation is small, the mechanical abrasion to the pipeline is small, and the gas-liquid separation device is only suitable for transporting powder substances with small viscosity and light specific gravity; the pulse gas conveying consumes larger power, and has quicker mechanical abrasion to the pipeline, but can convey the powder substance with moderate viscosity and larger specific gravity, and the equipment failure is relatively lower.
In summary, the pulse gas transportation is a powder substance transportation mode suitable for most working conditions; present pulse gas conveying equipment adopts the pressure limiting valve mode more, and the structure is more complicated, and concrete working method is: when the pressure in the air bag is higher than the set pressure, the pressure limiting valve is opened to supply air to the conveying pipeline, and when the pressure in the air bag is lower than the set pressure, the pressure limiting valve is closed, and no air is supplied to the conveying pipeline; the gas supply mode has long pulse period, low pulse frequency and poor pulse effect, so that the equipment has high failure rate when powder substances are conveyed, and the normal production is not facilitated.
