Abstract
The utility model discloses a level indicator. The level indicator comprises a protective box, a rocker arm and a shaft, which is characterized in that: the shaft is arranged in the protective box and vertically fixed with the rocker arm, a touch head is arranged on the upper end of the rocker arm and rotates along the shaft together with the rocker arm; after the touch head rotates to contact with a switch contact, the opening and closing operation is achieved; the lower end of the rocker arm is arranged outside the protective box and the bottom of the rocker arm is connected with an inclined baffle which is arranged in a material bin. The level indicator has features of simple structure, reliability, stability, low cost and basically zero maintenance, and solves the problems of the prior art that the existing level indicator cannot stably and reliably prove accurate signals and the complex to maintain. The level indicator can be applied to detecting the charging level of similar alloy bins.
Description
Technical field
The utility model relates to a kind of level-sensing device, belongs to the Automatic Measurement Technique field.
Background technology
Large-scale metallurgical enterprise can add various alloy materials automatically according to institute's steelmaking kind and molten steel composition in ironmaking, steelmaking process, automatical feeding system has become the important process link that intelligence is smelted, wherein, the whether accurate interlocking to automatic system of material level detection signal is enabled, is stopped playing a crucial role.The level-sensing device that uses at present is substantially as condenser type, blocking rotary type etc., though capacitance level meter is highly sensitive, the material powder of feeding process generation can be attached on level-sensing device, sends the rub-out signal false alarm, and causing can not material loading; Though the blocking rotary type level-sensing device can accurately reflect the feed bin situation, because of its complicated in mechanical structure, the frequent use makes spring stress tired, and trouble spot is many, and equipment must periodic replacement.
Under the abominable working environment of high pollution, high dust, accurate signal can not be stablized, be provided reliably to above level-sensing device, and complex structure must provide 220V or 24V working power, and trouble spot is many, to maintenance, brings difficulty.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of level-sensing device, solve level-sensing device under any working environment and can not stablize, provide reliably accurate signal, the complex structure trouble spot is many, the difficult problems such as 220V or 24V working power must be provided, met and carried out the detection of alloy feed bin material loading position in automatical feeding system, can measure steady in a long-term, reliably bulk or piece, the mixed alloy material material level of powder, sent detection signal accurately.
The technical solution adopted in the utility model is: a kind of level-sensing device, comprise the protection box; rocking arm; axle, it is characterized in that: be provided with axle in described protection box, axle is vertical with rocking arm fixing; the rocking arm upper end is provided with meets and discusses; meet and discuss and rotate along axle with rocking arm, contacts with switch contact after the rotation of meeting and discussing, and realizes opening and closing operations; The rocking arm lower end is positioned at outside the protection box, and the rocking arm bottom connects baffle plate, and baffle plate is obliquely installed, and is positioned at feed bin.
Described rocking arm is 60 ° along the maximum angle of axle rotation.
Described meeting and discussing met and discussed for magnetic.
Described protection box bottom is opening.
This level-sensing device is fit to be arranged on the appropriate location at feed bin top.
The utility model is a kind of simple and practical upper material-level detecting device of making according to lever principle.When reinforced, in feed bin, alloy material is piled up, material level rises, and when rising to certain altitude, it is stressed that alloy material promotes baffle plate, baffle plate moves up, drive rocking arm and rotate along axle, magnetic is met and discussed near switch contact, output signal to PLC after the opening and closing points closure, interlocking system is enabled, and automatical feeding system stops material loading; In feed bin, the alloy material material level descends, and makes catch lose support, and magnetic is met and discussed and left switch contact, and opening and closing points disconnects, and automatical feeding system allows reinforced.
The beneficial effect that the level-sensing device that the utility model provides brings:
⑴ this device realizes that principle is simple, it is convenient to implement, and, without any electric, machinery control, installs simply non-maintaining;
⑵ coming into operation of this material-level detecting device, can provide the material level detection signal for a long time, accurately, reliably, reaches the serviceable life of extension device, reduce equipment failure, reduce costs, liberation labour's purpose, be particularly useful for the abominable raw material systems of environment such as metallurgy industry.
Below in conjunction with drawings and Examples, the utility model is described further.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 is the protection box, and 2 for meeting and discussing, and 3 is axle, and 4 is rocking arm, and 5 is baffle plate, and 6 is switch contact.
Embodiment
Embodiment:
As shown in Figure 1, a kind of level-sensing device, comprise protection box 1, Rocker arm 4, axle 3 is characterized in that: be provided with axle 3 in described protection box 1, axle 3 is vertical with Rocker arm 4 fixing, and the Rocker arm 4 upper end is provided with meets and discusses 2, meet and discuss 2 with Rocker arm 4 along axle 3 rotation, contact with switch contact 6 after 2 rotations of meeting and discussing, realize opening and closing operations; The Rocker arm 4 lower end is positioned at outside protection box 1, and the Rocker arm 4 bottom connects baffle plate 5, and baffle plate 5 is obliquely installed, and is positioned at feed bin.
Described Rocker arm 4 is 60 ° along the maximum angle of axle rotation.Described meeting and discussing 2 met and discussed for magnetic.Described protection box 1 bottom is opening.
Concrete method for making is: (1) the utility model material-level detecting device by the protection box, meet and discuss, axle, rocking arm, baffle plate, switch contact form; (2) meet and discuss and select magnetic to meet and discuss, the baffle plate that rocking arm connects is selected lighter weight, baffle plate that lifting surface area is larger; (3) detecting core apparatus is that plug-in type is installed with the protection box, and the protection box is without bottom surface, can laying dust affect the normal operation of pick-up unit; Feasibility while (4) considering the material-level detecting device installation, should keep certain distance with charge door during installation, damaged by alloy material while avoiding reinforced.
Implementation method is: when reinforced, in feed bin, alloy material is piled up, material level rises, and when rising to certain altitude, it is stressed that alloy material promotes baffle plate, baffle plate moves up, drive rocking arm and rotate along axle, magnetic is met and discussed near switch contact, output signal to PLC after the opening and closing points closure, interlocking system is enabled, and automatical feeding system stops material loading; In feed bin, the alloy material material level descends, and makes catch lose support, and magnetic is met and discussed and left switch contact, and opening and closing points disconnects, and automatical feeding system allows reinforced.
