Abstract
The powder conveying device comprises a suction bin and a main airflow channel, wherein the suction bin comprises a first bin and a second bin, ventilating cloth is arranged between the first bin and the second bin, a powder inlet is formed in the first bin, a fluidizing airflow inlet is formed in the second bin, the main airflow channel comprises an air inlet pipe and an air outlet pipe, a gap is formed between the air inlet pipe and the air outlet pipe, and the gap is arranged in the first bin. One improvement is that a threaded interface is arranged between the pipe wall of the air outlet pipe and the bin wall of the first bin. Another improvement is that the powder inlet is a plurality of annular slits on the wall of the first bin. The structure is simple, the cost is low, and the processing is easy; the powder can be collected and conveyed from the lower part to the higher part, and can be conveniently placed in any appointed storage area; the suction bin sucks powder through negative pressure, and the powder is conveyed in positive pressure after entering the conveying pipeline, so that the energy-saving dust collector is more energy-saving than a dust collector and other dust collecting equipment.
Description
Technical field
The present invention relates to a kind of powder feedway.
Background technology
Industry such as building materials, metallurgy usually needs in the production process granular material is carried between different production facilitiess, and prior art is to utilize low-pressure air to be blown into the material pipe by breather cloth, makes powder become flow-like, and powder slides to discharging opening by under the gravity.This equipment can only be carried material from high to lower, if desire is delivered to eminence from lower, existing installation can not be realized.In addition, owing to causing granular material, reasons such as powder load transfer device poor sealing, equipment obstruction leak, the material that leaks mostly is finished product or half-blank, if untimely cleaning is reclaimed, not only cause and produce waste, influence the normal operation of equipment, also be unfavorable for plant maintenance and maintenance, dust from flying also can cause contaminated environment, is detrimental to health, and is badly in need of a kind of powder cleaning load transfer device in the production.
Summary of the invention
The problem to be solved in the present invention is to provide a kind of powder feedway, and it is simple in structure, and is easy to operate.
The present invention adopts following technical scheme: comprise suction storehouse and main air flow passage, described suction storehouse comprises first storehouse and second storehouse, be provided with breather cloth between first storehouse and second storehouse, first storehouse is provided with the powder inlet, second storehouse is provided with the fluidized gas inflow entrance, described main air flow passage comprises air inlet pipe and freeing pipe, is provided with the gap between air inlet pipe and the freeing pipe, and described gap is located in first storehouse.
Its principle is: utilize the principle of Venturi tube, and promptly when obstacle is crossed in wind, lower in the backside gas pressure of obstacle, and can produce air flows and adsorption.The air that when air pressure is 40～60KPa sprays into freeing pipe from the air inlet pipe of main air flow passage, to form negative pressure around the gap between air inlet pipe and freeing pipe, promptly this zone has mass air flow and is inhaled in first storehouse from powder inlet, simultaneously, air upwards sprays into first storehouse from the fluidized gas inflow entrance feeding in second storehouse and from breather cloth, the powder that enters first storehouse is promptly upwards blown afloat into the airborne dust state, powder in first storehouse and air promptly form certain mixture ratio, that is be to allow powder reach fluidized state, the continuous like this powder that enters first storehouse, just can be inhaled in the freeing pipe continuously from the gap location between air inlet pipe and the freeing pipe with air-flow, again with air-flow from ducting to the destination, thereby reach the powder that accumulates around this device is cleared up the purpose that reclaims and carry.
A kind of improvement is to be provided with hickey between the bulkhead in the tube wall of described freeing pipe and first storehouse.This structure can be controlled the negative pressure height by the gap clearance of regulating air inlet pipe and freeing pipe, thus the ability of regulating the absorption of suction storehouse and carrying powder.
The another kind of improvement is several annuluss on the bulkhead that described powder inlet is first storehouse.The powder inlet of this structure, layout is even, and pan feeding is effective.
Adopt the present invention to have following advantage: 1, simple in structure, cost is low, and is easy to process; 2, can collect powder it is delivered to eminence by lower, and can put easily to any appointment storage areas; 3, the suction storehouse is by the negative-pressure adsorption powder, enters behind the delivery duct to carry for malleation, and is more energy-conservation than dust collecting fan and other dust collection device.
This equipment is at present by testing usefulness, and test shows, the density of the operational throughput of powder and delivery head and powder is relevant with the air pressure of main air flow passage, in powder density less than 5000Kg/m
3Situation under, the delivery head of powder can reach 50 meters when the air pressure of main air flow passage was 40～60KPa, operational throughput can per hour can be carried 4～6 tons of powders by adjusting the caliber adjusting of air inlet pipe and freeing pipe when the air inlet pipe caliber is 50mm.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
The specific embodiment
As shown in Figure 1, an embodiment of the present invention, comprise suction storehouse 1 and main air flow passage 2, described suction storehouse 1 comprises that being provided with breather cloth 5, the first storehouses 3 between first storehouse 3 and 4, the first storehouses 3, second storehouse and second storehouse 4 is provided with powder inlet 6, second storehouse 4 is provided with fluidized gas inflow entrance 7, described main air flow passage 2 comprises air inlet pipe 8 and freeing pipe 9, is provided with gap 11 between air inlet pipe 8 and the freeing pipe 9, and described gap 11 is located in first storehouse 3.
Its principle is: utilize the principle of Venturi tube, and promptly when obstacle is crossed in wind, lower in the backside gas pressure of obstacle, and can produce air flows and adsorption.The air that when air pressure is 40～60KPa sprays into freeing pipe 9 from the air inlet pipe 8 of main air flow passage 2, to form negative pressure around the gap 11 between air inlet pipe 8 and freeing pipe 9, promptly this zone has mass air flow and is inhaled in first storehouse 3 from powder inlet 6, simultaneously, air upwards sprays into first storehouse 3 from fluidized gas inflow entrance 7 feedings in second storehouse 4 and from breather cloth 5, the powder that enters first storehouse 3 is promptly upwards blown afloat into the airborne dust state, powder and air in first storehouse 3 promptly form certain mixture ratio, that is be to allow powder reach fluidized state, the continuous like this powder that enters first storehouse 3, just can be inhaled into continuously in the freeing pipe 9 from the gap 11 between air inlet pipe 8 and the freeing pipe 9 with air-flow, again with air-flow from ducting to the destination, thereby reach the powder that accumulates around this device is cleared up the purpose that reclaims and carry.
A kind of improvement is to be provided with hickey between the bulkhead in the tube wall of described freeing pipe 9 and first storehouse 3.This structure can be controlled the negative pressure height with gap 11 spacings of freeing pipe 9 by regulating air inlet pipe 8, thus the ability of regulating 1 absorption of suction storehouse and carrying powder.
The another kind of improvement is several annuluss 10 on the bulkhead that described powder inlet 6 is first storehouses 3.The powder inlet of this structure, layout is even, and pan feeding is effective.A kind of example of optimization is that the seam of annulus 10 is wide to be 8～15 millimeters.
The present invention is not limited to the concrete structure of the foregoing description, and the equivalent transformation of other homogeneous structure all falls within protection scope of the present invention.
