Description
Technical field
The present invention relates to a kind of powder conveying apparatus, concrete is a kind of powder conveying apparatus.
Background technology
Existing granular material mode of movement includes: suction and conveying formula, pressure sending type, hybrid and four kinds of forms of fluid delivery type.1, suction and conveying formula is when in conveyance conduit, gas pressure is lower than atmospheric pressure, is called that suction and conveying formula is air conveying.When after fan starting, when reaching certain vacuum in pipeline, air in air is portable is entered pipeline with material by suction nozzle, and is transported to the separator of delivery end along pipeline.In the separator, material separates with air, and isolated material is drawn off by separator bottom, and air is by being discharged in air through blower fan after cleaner unit dedusting.Suction and conveying formula pneumatic transport equipment have the advantages that feeding device is simple, simultaneously from several absorbing materials, can ask that size and location limits unlimited by suction place sky.It major downside is that because the vacuum in pipeline is limited, therefore fed distance is limited；The sealing requirements of device is significantly high；When there is no fine dedusting by the gas of blower fan, blower fan abrasion will be accelerated.2, pressure sending type: when gas pressure is higher than atmospheric pressure in transfer pipeline, be called that pressure sending type is air conveying.Compression air is inputted in loader by blower fan, makes material mix with gas, and the gas material of mixing enters separator through conveyance conduit.In separator, gentle stopping separates material, and material is drawn off by separator bottom, is discharged in air after gas removing dust device dedusting.Pressure sending type Pneumatic conveyer have the advantages that fed distance is farther out；Material can be transported to a few place simultaneously.It major downside is that loader is more complicated；Can only simultaneously by a feed.3, hybrid: hybrid air conveying to be constituted jointly by suction and conveying formula and pressure sending type.Being negative pressure in suction and conveying part, conveyance conduit, material is sucked by suction nozzle, enters separator through pipeline and separates.It is malleation in force feed part, conveyance conduit, separator bottom the material drawn off is sent to separator and is easily separated.Negative pressure in pipeline and the malleation in pipeline are all caused by same Fans.Having the advantages that of hybrid Pneumatic conveyer from several absorbing materials, can be delivered concurrently into a few place material again, and fed distance is farther out.It major downside is that the gas containing material is by blower fan, makes blower fan abrasion accelerate；Whole appliance arrangement is more complicated.4, fluid delivery type: fluid delivery type is air conveying is a kind of deformation type of material suspended conveying, and air conveyer flume is exactly this conveyer device.Its effect high-volume is little for air open close too much lonely L air-permeable layer to be filled in people's granular material, makes material become similar fluid properties, thus can be flowed to low side by the high-end of trough.The conveying of material group is air conveying also referred to as bolt stream, is the material bolt that the material in pipeline is divided into many interruptions by gas pressure, and is carried along pipeline by strength promotion.
Concrete patented technology, a kind of device for pneumatic conveying loose unpacked material especially granular material as disclosed in 101511712A, there is conveyance conduit, conveying gas source and at least one extracting position, this conveyance conduit determines the transport path for loose unpacked material, this conveying gas source be connected on conveyance conduit and along transport path direction input conveying gas, by this extracting position, gas is derived from conveyance conduit.Proposing by the present invention, multiple extracting positions are arranged on conveyance conduit along spaced the turning up the soil of transport path, and described extracting position is able to regulate flow.Thus, present invention achieves from conveyance conduit, controlledly take out excessive gas.Thus can reduce gas velocity so that conveying keeps tranquil and stable.Thus can cancel cross section in order to maintain the required conveyance conduit of tranquil and stable conveying up to now and hierarchically become big along transport path., there is structure complexity in this granular material device, transfer efficiency is low, and the problem easily occurring that dust blocking, blowback, charging are not smooth, revealing.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of powder conveying apparatus, it is possible to overcome the drawbacks described above of prior art.
For reaching above-mentioned purpose, the present invention provides following technical scheme:
A kind of powder conveying apparatus, including pressure fan, feed arrangement, powder material storehouse and transfer pipeline, the entrance of described transfer pipeline seals UNICOM with pressure fan air outlet, the powder charging aperture of described transfer pipeline seals UNICOM with feed arrangement, the discharging opening of described transfer pipeline seals UNICOM with powder material storehouse, described feed arrangement includes barrel, pore mesh screen it is provided with bottom described barrel, described barrel top is provided with feed hopper, described feeding funnel bottom part is provided with discharge nozzle, and described discharge nozzle is arranged in barrel.
Further, described feed hopper top is additionally provided with the sealing lid preventing dust from revealing.
Further, described pressure fan is roots blower.
The beneficial effects of the present invention is: the powder conveying apparatus of the present invention by arrange on transfer pipeline can the feed arrangement of supplies charging so that powder can enter transfer pipeline more smoothly, be also possible to prevent fed material from being blocked simultaneously.
Accompanying drawing explanation
In order to make the purpose of the present invention, technical scheme and beneficial effect clearly, the present invention provides drawings described below to illustrate:
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
