The device has the advantages of simple and compact structure, low cost, reliable performance, simple maintenance, low operation cost and high control performance.
Description
Technical field
The utility model is mainly concerned with the material transfer equipment field, refers in particular to a kind of equipment that is applicable to that powdery or granular material are closely carried.
Background technology
For the conveying of powdery or granular material, the form that generally is configured to common vane feeder cooperation jet dredge pump of existing traditional mode of movement.But, this mode of movement has the following disadvantages: air consumption is big, transfer line gas powder flow rate fast, pipeline serious wear or the like, the air locking of the most key is vane feeder can be bad, will cause the requirement of operational throughput out of reach or not smooth phenomenon occur carrying.
The utility model content
The technical problems to be solved in the utility model just is: at the technical matters that prior art exists, the utility model provides a kind of simple and compact for structure, with low cost, dependable performance, maintenance is simple, over-the-road expense is low, controller performance the is high continuous Pneumatic conveyer of little positive low pressure.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
The continuous Pneumatic conveyer of a kind of little positive low pressure, it is characterized in that: comprise surge bunker and gas-solid feed appliance, described gas-solid feed appliance comprises blending box, the nozzle that mixes expander and link to each other with outside air feed equipment, the feeding end of described mixed expander is connected with the discharge end of blending box, the discharge end of described surge bunker links to each other with the feeding end of blending box, and the outlet side of described nozzle is towards the feeding end that mixes expander.
As further improvement of the utility model:
The discharge end of described surge bunker links to each other with the feeding end of blending box with the electric lorry air valve by manual push-pull valve successively.
Described nozzle be can be in blending box vacuum annular nozzle.
Described surge bunker is provided with freeing pipe.
Described outside air feed equipment is Roots blower or Air compressor.
The feeding end of described blending box up, described surge bunker is installed in the top of blending box.
Compared with prior art, advantage of the present utility model is:
1, the utility model combines negative pressure charging and malleation conveying dexterously by the nozzle of ring-type is set, and when conveying pipeline infeeded, feed appliance played the limit and quickens the effect of conveying simultaneously, and does not have bigger loss of pressure with powder; The utility model can also make in the whole delivery duct material and air-blending than to optimum value, and the fluidised form voltinism is good.Simultaneously,, adopt the science processing technology, more effectively reduced the wearing and tearing of equipment, prolonged the service life of equipment by precise design and calculating.
2, during the utility model feed, Volumetric efficiency is very little with change in rotational speed, and it is wide to adapt to range of speed, and Volumetric efficiency is very little with the variation of running pressure, self adaptation from low pressure to the operating mode scope of pressure; And good seal performance, the revolution air leakage is low.Rotating speed height of the present utility model, rotating speed have been broken through the global problem that feed capacity descends under the high rotating speed up to 60rpm, have increased feed capacity.The utility model adopts proprietary anti-card technique, though under fast state the delivery of particulate material material, also can smooth operation.

The specific embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
As shown in Figure 1, the continuous Pneumatic conveyer of little positive low pressure of the present utility model, comprise surge bunker 1 and gas-solid feed appliance, surge bunker 1 is provided with inlet point 1, the gas-solid feed appliance comprises blending box 4, the nozzle 6 that mixes expander 5 and link to each other with outside air feed equipment 7, the feeding end that mixes expander 5 is connected with the discharge end of blending box 4, and the discharge end of surge bunker 1 links to each other with the feeding end of blending box 4, and the outlet side of nozzle 6 is towards the feeding end that mixes expander 5.
In the present embodiment, the discharge end of surge bunker 1 links to each other with the feeding end of electric lorry air valve 3 with blending box 4 by manual push-pull valve 2 successively.Electric lorry air valve 3 adopts the electric lorry air valve of high-accuracy manufacturing, and dense block gas performance is high, does not leak ash and blanking is smooth and easy.
In the present embodiment, nozzle 6 be can be in blending box 4 vacuum annular nozzle, can produce high vacuum, can not produce turbulent flow again and bring energy loss, and have that the ejection material speed is fast, continuity good, be advantage such as dispersed.
For the powder of different stacking densities, corresponding various forms of gas-solid feed appliances are provided with the surge bunker 1 of special tectonic.Surge bunker 1 is provided with freeing pipe 101, and is smooth and easy to guarantee the powder blanking.
In the present embodiment, outside air feed equipment 7 is Roots blower or Air compressor, is used to provide power gas source, is transported to the destination behind blending box 4, mixed expander 5, delivery duct.
During work, granular material enters surge bunker 1 by inlet point 102, and surge bunker 1 appropriate design is the structure that is easy to blanking.The feed opening place is provided with the usefulness of manual push-pull valve 2 with convenient maintenance; Then, by electric lorry air valve 3 material is advanced in the blending box 4 of gas-solid feed appliance.The gas-solid feed appliance is the principle of Venturi effect, that is: with air-flow from the coarse to fine, to accelerate gas flow rate, make gas form one " vacuum " district at the rear side of exit end, to realize the conveying of powder.By the nozzle 6 that ring-type is set, negative pressure charging and malleation conveying are combined dexterously, when conveying pipeline infeeded, feed appliance played the limit and quickens the effect of conveying simultaneously, and does not have bigger loss of pressure with powder; The utility model can also make in the whole delivery duct material and air-blending than to optimum value, and the fluidised form voltinism is good.Simultaneously,, adopt the science processing technology, more effectively reduced the wearing and tearing of equipment, prolonged the service life of equipment by precise design and calculating.
