Description
Technical field
It is more particularly to a kind of that there is the dry blend conveying dress for weighing function the present invention relates to a kind of solid material conveying equipment
Put.
Background technology
In dry blend transportation art, the filling that dry blend is carried out using hopper is a kind of more conventional feed way,
Because its device structure is simple, facilitate easy-to-use, therefore be widely used in each engineering field.In practical application, lead to
Hopper and its appurtenances structure are relatively simple used by often, and charging process is more extensive, and therefore, it is difficult to meet that some pairs add
The application requirement of the higher occasion of doses accuracy requirement.To solve this problem, some have the relevant conveying for weighing function
Equipment is developed, such as：Publication No. CN204660891U Chinese patent application (hereinafter referred to as CN204660891U) is public
" the weighing type spiral conveying device " opened, Publication No. CN202195867U Chinese patent application are (hereinafter referred to as
CN202195867U) disclosed the cement hopper of precise " can " etc..
However, the existing conveying equipment including the said equipment is remained in certain deficiency.Such as " claiming for CN204660891U
Weight formula helix transporting device ", its hopper blanking part employs the complex one-way spiral lock of structure and rotatory feeder valve etc.,
It is unfavorable for the structure simplification and the lifting of reliability of equipment；Hopper does not use anti-arch camber measure, holds during conveying for dry blend
Arch camber obstruction easily occurs；Used screw(-type) feeder is restricted by material dispersion uniformity etc. factor, therefore knot of weighing
The accuracy and reliability of fruit be not high.The and for example CN202195867U cement hopper of precise " can ", its hopper is not also adopted
Arch camber obstruction easily occurs with anti-arch camber measure, during conveying for dry blend；Because dry blend is solid material, therefore its material
The dry blend of the positions such as bucket, flexible pipe and conveying screw rod inside is easily accumulated so that dry blend forms internal support, notable shadow
Ring the accuracy and reliability of weighing result.
In summary, using the existing dry blend conveying equipment of hopper, there are still the accuracy of such as weighing result and can
It is not high by property；Hopper does not use anti-arch camber measure, and arch camber obstruction easily occurs during conveying for dry blend；The local knot of equipment
The defects of structure is complex.
The content of the invention
To solve, weighing result accuracy existing for the existing dry blend conveying equipment using hopper and reliability be not high, expects
The defects of arch camber obstruction, easily occurs for bucket capacity, and the invention provides a kind of dry-mixed material conveying device for having and weighing function.
There is the dry-mixed material conveying device for weighing function to include hopper body, hopper base, horizontal feed pipeline, level for this
Conveyance conduit support, vertical transport pipeline and vertical transport pipeline support；The hopper body is provided with hopper feed mouth, material
Bucket feed opening, vibrating motor and hopper support plate, hopper body are supported on the hopper base by hopper support plate, hopper
The unlatching of feed opening is controlled with closing by butterfly valve；The hopper base is placed on horizontal feed pipeline support, hopper base and water
Shock absorber is set between flat conveyance conduit support, and the leg of horizontal feed pipeline support has Weighing module；The level is defeated
Send pipeline to be arranged on horizontal feed pipeline support, propeller blade, one end of horizontal feed pipeline are provided with horizontal feed pipeline
Provided with the horizontal drive motor for driving the propeller blade；The other end of horizontal feed pipeline is horizontal conveying pipe way discharging device
Mouthful, horizontal conveying pipe is said material mouth and is connected by expansion joint with vertical transport pipeline charging aperture；On the horizontal feed pipeline
Provided with horizontal feed pipeline charging aperture, horizontal feed pipeline charging aperture is connected by flexible connecting pipe with hopper feed opening；It is described
Vertical transport pipeline is supported using vertical transport pipeline support, and propeller blade, vertical transport pipeline are provided with vertical transport pipeline
Upper end be provided with and be used to drive the vertical driving motor of the propeller blade；Said for vertical tranporter the lower end of vertical transport pipeline
Material mouth.
It is also provided with feeding velar plate on the hopper feed mouth.
It is preferred to be additionally provided with reinforcement on the hopper support plate.
The material of the flexible connecting pipe is preferably canvas or rubber.
The expansion joint is preferably rubber expansion joint.
It is preferred that broken arch gas dish is additionally provided with the hopper body.
Present invention employs the anti-arch camber measures such as vibrating motor are set on hopper body, it effectively prevent dry blend and expecting
The problem of arch camber obstruction occurs in bucket body.However, vibration can interfere significantly with the normal of weighing equipment caused by vibrating motor etc.
Work, hence it is evident that reduce the accuracy and reliability of weighing result.Therefore, the support knot of the invention by the dry-mixed material conveying device
Structure is designed to the two parts being separated from each other, and carries out isolating technique using shock absorber between the two.Practical application shows, the design
The interference of the weighing equipment such as vibrating motor is effectively prevent, achieves good effect.
Another subject matter for running into the design process of dry-mixed material conveying device of the present invention is：Directly to hopper sheet
Body is weighed obtained result and still suffers from the problem of obvious in terms of accuracy and reliability.It has been investigated that cause this
The reason for problem occurs, which is essentially consisted in during dry blend drops down onto horizontal conveying pipe road under by hopper, easily accumulates, and makes
The dry blend for obtaining bottom forms internal supporting role to the dry blend on top, and then causes the accuracy and reliability of weighing result
Significantly deterioration.Therefore, used weighing equipment (i.e. Weighing module) is placed in the lowermost end of supporting structure by the present invention, coordinate soft
The reasonably combined use of the associated components such as property adapter, expansion joint, realize hopper body part and horizontal feed pipeline part
Weigh simultaneously, be inherently eliminated the influence of foregoing problems, it is ensured that the accuracy and reliability of weighing result.
In summary, the dry-mixed material conveying device with weighing function of the invention can be real in dry blend course of conveying
The weighing of existing dry blend, the accuracy and reliability of weighing result are high, have simple for structure, and easily operated, equipment cost is relatively low
The advantages that, it disclosure satisfy that the application demand of weighing accuracy and the higher occasion of reliability requirement.
