Description

Powdered or granular material unloader

Affiliated technical field

The utility model relates to a kind of device for discharging of Powdered or granular material, the Powdered or granular material (as: chemical fertilizer, salt, carbohydrate, chemical, coal burning synergistic compound etc.) that especially has humidity and viscosity can make these materials effectively quantitative, control the unloader that it evenly flows downward.

Background technology

Have the Powdered or granular object of humidity and viscosity, its main common feature is: the multiple proterties with particle, Powdered, deliquescent, viscosity.It is that certain humidity is arranged, and it has certain viscosity.If it is placed in the container, allow it with the formula of putting of low discharge from the trend current downflow.At this time be to be difficult to flow downward by the weight of self.Because these materials have certain viscosity, therefore have more existing adhesion and do not descend and make somebody a mere figurehead or make mobile shortcomings such as outlet obstruction.If these materials and other different types of Powdered or granular material, the mixed preparing that the mode that flows is proportional, it the heavy handled situation will occur.Patent of invention (01138848.X) coal burning synergistic compound as China.Because do not have preferably, actv. controls its unloader that evenly flows downward, its this coal burning synergistic compound will with the even mixed preparing of coal the time.Can only lean on the way that evenly scatters manually.So just increased the productive costs of enterprise.So its popularization is for many years never approved by vast enterprise.So just restrict the benefit performance of this patent.

Powdered or the granular material that has certain humidity and viscosity at present will make itself and other different types of Powdered or granular material carry out the method for proportional mixed preparing:

1, under the general situation all be several different materials in proportion weighing good after, these several different objects are poured on carry out mechanical agitation in the puddle mixer or be poured in the container mixing manually again.This method is simple and reliable, but labour intensity is big, productive costs is higher, can not operate with the continuous-flow type form.

2, scatter uniformly by manually way and mixing on other the material or on the manufacturing line that flows.Its way is effective, all is to be used for the not high manufacturing line of some proportion requirement generally.(as: on fertilising or other some industrial flow-lines).But its productive costs is also very high, along with the progressively raising of human cost, so its productive costs is also more and more higher.And be difficult to adapt to the production requirement of modern mechanicalization.

3, mechanical vibration method, this method is simple and practical, cost is lower.Not having under the Powdered or granular material situation of humidity and viscosity at some, is actv..If have the Powdered or granular object of humidity and viscosity, particularly in low discharge, this method will be like water off a duck's back.

4, mechanical presses method, existing mechanicalization all are difficult to the effect that reaches desirable.As: spiral extrusion process, piston-type extrusion method.These two kinds of methods can make the Powdered or granular material that has certain humidity and viscosity become bulk and extrude.And complex structure, cost is higher.

5, pressurized air spraying, this method also is a complex structure, cost is higher, and is not strong in some field operability.

6, other some as: automatic fertilizer spreaders all is shortcomings such as complex structure, cost height.As the practical patent of China (CN85102411B), a kind of fertilizer applicator that is fertilizer apparatus.It is to adopt compositions such as mixer, roller and fertilizer regulating control.

Summary of the invention

It is a kind of that the purpose of this utility model is to provide, and structure is single, the automatic machinery of the regulatable Powdered or granular material discharging of flow.

The utility model is realized by following technical scheme: at the upright main shaft of bulk tank central authorities, main shaft is connected with change speed motor on the container cover.Main shaft axially around arrange in the mode of spiral elongated blade be housed, and there is certain included angle during blade installation and the sagittal plane of main shaft.Utilize a plurality of elongated blade rotation that have certain angle of inclination,,, will make material produce the power that flows downward like this so its makes material that a kind of downward pressure be arranged when rotating because blade has certain angle of inclination.Because blade is elongated rigidity object, when so it rotates, can carry out samsara to all materials in the container stir and scrape pressure, and can form lump material to some during elongated blade rotation and smash, so its rotates and scrapes that to press be to make object form bulk.Elongated blade is to be driven by regulatable change speed motor, therefore can be by the variation of motor speed, or other regulatable automation transmission device is controlled the size of its flow.The invention has the beneficial effects as follows:

1, simple in structure, easy to manufacture, easy to maintenance, cheap, so cost is lower.

2, easy to operate, its flow can be controlled by change in rotational speed simultaneously, so can use on the higher manufacturing line of flow control proportion requirement.

3, the present invention is generally as long as with the small-sized change speed motor of tens watts or several hectowatts, just can realize automated production, so energy consumption is lower.

4, can realize the production requirement of modern mechanicalization, and can both be applied in a lot of fields.
