Description
Technical field
The utility model belongs to weighing-appliance technical field, in particular to a kind of indirect Weighing type level-sensing device.
Background technique
For a long time, liquid, powdery, granular material are stored, enclosed drum magazine is typically used, that is, expects
Storehouse.In this way, in feed bin material number, be exactly important information concerned by people, in order to know this information, just produce material position
Instrument.
Existing frequently-used level-sensing device can be divided into the type of continuously displaying and interruption display type, and continuously displaying type, there are commonly radio frequencies
Admittance type, direct weighing type and sensor special.Interruption display type mainly has mechanical measurement type and damp type.
Radio frequency admittance type major defect is that its display precision and effect are usually influenced by material properties and environmental factor, can
It is poor by property, it is often required to silo roof installation maintenance, so installation maintenance difficulty is big.
Direct weighing type is that large-scale weighing sensor is installed in support device, and advantage is that display is accurate, and disadvantage is exactly shadow
Support device structure safety is rung, while weighing and being limited by sensor capability.
The shortcomings that sensor special type be it is at high cost, limit the range of stress of support device, it is difficult to promote and apply.
Mechanical measurement type is to drive weight measurement charge level height with mechanical device to calculate inventory, silo roof installation.Disadvantage
It is installation maintenance inconvenience, failure is more, and the service life is short, cannot continuously display.
Damp type level-sensing device is to be inferred installation point either with or without material, bulkhead peace according to the rotary resistance size of measurement motor
Dress.The disadvantage is that installation maintenance is inconvenient, the service life is short, cannot continuously display.
The utility model patent of application number 201721695264.9 discloses a kind of indirect Weighing type level-sensing device, and transmission rod is not
It can well and interfacial contact, error are big.
The advantages of in order to retain the above various modes, produces this level-sensing device at the shortcomings that overcoming the above various modes.
Utility model content
To solve existing level-sensing device, structure is complicated, and installation maintenance is difficult, adaptability and poor reliability, and failure more service life are short etc.
Deficiency, the utility model provide a kind of indirect Weighing type level-sensing device.
The purpose of this utility model adopts the following technical solutions realization: a kind of indirect Weighing type level-sensing device, including original
The support device of feed bin is equipped with upper bracket and undersetting on the vertical direction of the side of support device, passes through on upper bracket
Fixing screws are fixed with general weighing sensor, install coupling piece by adjusting nut between weighing sensor and undersetting,
Coupling piece upper and lower side is screw-rod structure, and upper end is connected with weighing sensor, the signal wire connection universal weighing instrument of weighing sensor
Table.
Preferably, it is coated between the coupling piece and raw material cabin support device and couples cream.
Technique effect and advantage:
This level-sensing device scheme is convenient for installation and maintenance without mechanical movement compared with resistance rotation type and mechanical type level-sensing device, uses
Service life is long, continuously displays, high reliablity.
This level-sensing device scheme is compared with radio frequency admittance level-sensing device, and advantage is not influenced by environment and material properties, property
It can stablize, the service life is long, not upper silo roof installation, and installation maintenance is more convenient.
Compared with sensor special level-sensing device, advantage is to use general purpose transducer and facilitates adjusting this level-sensing device scheme
Coupling chip architecture, the scope of application is wider, draw materials it is easier for installation, be easier to promote the use of.
This level-sensing device scheme is compared with direct weighing type level-sensing device, and advantage is not influence support device structure safety, no
Scope limitation is weighed by sensor, it is at low cost, it is easier to promote.
The utility model using coupling piece can well with interfacial contact, reduce error, title it is more acurrate.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the indirect Weighing type level-sensing device of the utility model.
Specific embodiment
Technical solutions of the utility model are discussed in detail with reference to the accompanying drawing.
As shown in Figure 1, present embodiment discloses a kind of indirect Weighing type level-sensing devices, in the support device 1 of raw material cabin,
Upper bracket 3 and undersetting 7 are fixed, fixes general weighing sensor 4 with fixing screws 2 on upper bracket 3, is passed in weighing
Coupling piece 6 is installed with adjusting nut 8 between sensor 4 and undersetting 7,6 upper and lower side of coupling piece is screw-rod structure, and upper end and weighing pass
Sensor 4 is connected, the signal wire connection universal weighing instrument 5 of weighing sensor 4.
Working principle:
According to Hooke's law, when how much material changes in feed bin, stress suffered by support device 1 can occur to become accordingly
Change, so that the support device position between upper bracket 3 and undersetting 7, can generate corresponding deformation, the deformation is then by coupling piece
6, it is accurately transferred to weighing sensor 4, weighing sensor 4 then issues corresponding signal, weighed instrument 5 to weighing instrument 5
Processing just accurately shows the variation that material is how many in discharging bin, realizes the purpose of real-time display material position.
Adjusting nut 8 is both used for fixed coupling piece 6, is also adjusted for zero point.
The characteristics of this level-sensing device technical solution:

Tonnage material.
3, this level-sensing device scheme is applicable in the support device of the various ranges of stress using the coupling chip architecture of variable length.
4, this level-sensing device scheme adjusts zero point using adjusting nut, measures relatively reliable.
5, the characteristics of this level-sensing device scheme, is reasonably to use general weighing sensor and instrument, support and coupling piece
Effective combination.
6, the characteristics of this level-sensing device scheme be used in coupling plate shape kissed substantially with raw material cabin support device shape
It closes.
7, this level-sensing device Scheme Characteristics, which are to be coated between coupling piece and raw material cabin support device, couples cream.
This level-sensing device scheme is suitable for doing each plant feed bin of support device using the material (such as steel) of uniform material,
Such as cement bin, coal ash storehouse, feed bin, silo and various wet tanks are used.
The technical program had both been suitble to new feed bin to use, and was also suitable old material storehouse add-assembly.
Compared to the utility model patent of application number 201721695264.9, can be connect well with interface using coupling piece
Touching, reduce error, title it is more acurrate.
