Description

A kind of have the dry blend feedway weighing function
Technical field
The present invention relates to a kind of solid material load transfer device, particularly a kind of have the dry blend feedway weighing function.
Background technology
In dry blend transportation art, the filling adopting hopper to carry out dry blend is a kind of comparatively conventional feed way, because its device structure is simple, facilitates easy-to-use, is therefore widely used at each engineering field.In practical application, usual adopted hopper and appurtenances structure thereof are comparatively simple, and reinforced process is comparatively extensive, are therefore difficult to meet some application requirement to the higher occasion of feeding quantity accuracy requirement.For addressing this problem, some have and weigh relevant load transfer devices of function and be developed, as: publication number be the Chinese patent application (hereinafter referred to as CN204660891U) disclosed " weighing type spiral feedway " of CN204660891U, publication number is the Chinese patent application (hereinafter referred to as CN202195867U) of the CN202195867U disclosed cement hopper of precise " can " etc.
But the existing load transfer device comprising the said equipment remains in certain deficiency.As " the weighing type spiral feedway " of CN204660891U, its hopper blanking parts have employed the comparatively complicated one-way spiral lock of structure and rotatory feeder valve etc., are unfavorable for the designs simplification of equipment and the lifting of reliability; Hopper does not adopt anti-arch camber measure, arch camber easily occurs during conveying for dry blend and blocks; The screw feeder adopted by the restriction of the aspect factors such as material dispersion homogeneity, therefore the accuracy of weighing results and reliability not high.The cement hopper of precise " can " of and for example CN202195867U, its hopper does not adopt anti-arch camber measure yet, during conveying for dry blend, arch camber easily occurs and blocks; Because dry blend is solid material, the dry blend of the positions such as therefore its hopper, flexible pipe and conveying screw rod be inner is easily piled up, and makes dry blend form inner support, significantly affects accuracy and the reliability of weighing result.
In sum, adopt the existing dry blend load transfer device of hopper still to there is the accuracy of such as weighing result and reliability not high; Hopper does not adopt anti-arch camber measure, arch camber easily occurs during conveying for dry blend and blocks; The defects such as the local structure of equipment are comparatively complicated.
Summary of the invention
For solving weighing result accuracy that the existing dry blend load transfer device that adopts hopper exists and reliability is not high, the defects such as arch camber obstruction easily occur hopper, the invention provides and a kind of there is the dry blend feedway weighing function.
This has the dry blend feedway weighing function and comprises hopper body, hopper base, horizontal feed pipeline, horizontal feed pipeline support, vertical transport pipeline and vertical transport pipeline support; Described hopper body is provided with hopper feed mouth, hopper feed opening, vibrating motor and hopper support plate, and hopper body is supported on described hopper base by hopper support plate, and the unlatching of hopper feed opening is controlled by butterfly valve with closed; Described hopper base is placed on horizontal feed pipeline support, arranges Shock absorber between hopper base and horizontal feed pipeline support, and the leg of horizontal feed pipeline support has Weighing module; Described horizontal feed pipeline is arranged on horizontal feed pipeline support, is provided with screw blade in horizontal feed pipeline, and one end of horizontal feed pipeline is provided with the horizontal drive motor for driving this screw blade; The other end of horizontal feed pipeline is horizontal conveying pipe way discharging device mouth, and horizontal conveying pipe way discharging device mouth is connected with vertical transport pipeline inlet point by expansion joint; Described horizontal feed pipeline is provided with horizontal feed pipeline inlet point, and horizontal feed pipeline inlet point is connected with hopper feed opening by flexible connecting pipe; Described vertical transport pipeline adopts vertical transport pipeline stent support, and be provided with screw blade in vertical transport pipeline, the upper end of vertical transport pipeline is provided with the vertical driving motor for driving this screw blade; The lower end of vertical transport pipeline is vertical tranporter way discharging device mouth.
Described hopper feed mouth can also be provided with inlet point cover plate.
It is preferred for described hopper support plate being also provided with reinforced rib.
The material of described flexible connecting pipe is preferably canvas or rubber.
Described expansion joint is preferably rubber expansion joint.
It is preferred for described hopper body being also provided with broken arch gas dish.
Present invention employs and the anti-arch camber measures such as vibrating motor are set on hopper body, effectively prevent the problem that arch camber obstruction occurs dry blend in hopper body.But the vibration that vibrating motor etc. produce significantly can disturb the normal work of weighing equipment, significantly reduces accuracy and the reliability of weighing result.For this reason, the supporting structure of this dry blend feedway is designed to the two parts be separated from each other by the present invention, and between the two, adopt Shock absorber to carry out isolating technique.Practical application shows, this design effectively prevent the interference of the weighing equipment such as vibrating motor, achieves good effect.
Another subject matter that dry blend feedway of the present invention runs in the design process is: directly weigh obtained result to hopper body still exists obvious problem in accuracy and reliability.Find after deliberation, the reason causing this problem to occur mainly is that dry blend is easily piled up in the process being fallen to horizontal feed pipeline by hopper, make the dry blend of bottom form inner support effect to the dry blend on top, and then make the accuracy of weighing result and reliability significantly deteriorated.For this reason, adopted weighing equipment (i.e. Weighing module) is placed in the lowermost end of supporting structure by the present invention, coordinate the reasonably combined use of the associated components such as flexible connecting pipe, expansion joint, weigh while achieving hopper body part and horizontal feed pipeline part, fundamentally eliminate the impact of foregoing problems, ensure that accuracy and the reliability of weighing result.
In sum, of the present invention have the weighing that the dry blend feedway weighing function can realize dry blend in dry blend course of conveying, accuracy and the reliability of weighing result are high, have simple for structure, be easy to operation, the advantages such as equipment cost is lower, can meet the application demand of weighing accuracy and the higher occasion of reliability requirement.
