Description
Technical field
The present invention relates to a kind of material detection device, particularly a kind of material-level detecting device, the material level that is suitable for powder and particulate material detects, and belongs to material detection device field.
Background technology
In powder and particulate material storage and automation course of conveying, all need to install material-level detecting device, thereby obtain the state of material in container, with this, detect information realization monitoring material position and system automation control.Current material-level detecting device is substantially all to adopt photoelectric switch or approach switch etc., but powder and particulate material store and automation course of conveying in use photoelectric switch and approach switch, easily because the dust of feed bin inner chamber covers unrestrained or material, adhere to test surface and cause signal error.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the present invention proposes a kind of level detecting apparatus, and it can not be subject to dust or unrestrained the covering of a small amount of material and affect signal when detecting level of filler material.
Object of the present invention is achieved by the following technical programs:
A material-level detecting device, is characterized in that: it comprises housing, upper loose-leaf, lower loose-leaf, magnetic sensible switch and steel magnetic; A lateral opening of described housing; Described upper loose-leaf and lower loose-leaf are movably set in described shell nozzle and to playing buffer action inside and outside described shell nozzle, described upper loose-leaf top is rotatably connected to the top of described shell nozzle, described upper loose-leaf bottom is connected by hinge with described lower loose-leaf top, the bottom of described lower loose-leaf freely buckles the outside, bottom at described shell nozzle, and the bottom of described shell nozzle is also provided with the inclined-plane of the inside slippage in bottom of being convenient to lower loose-leaf; Described magnetic sensible switch is fixedly installed in described enclosure interior; Described steel magnetic is fixedly mounted on loose-leaf or lower loose-leaf inner side; When upper loose-leaf and lower loose-leaf are not subject to keeping naturally drooping state under Gravitative Loads to the squeese pressure of housing inner chamber, magnetic sensible switch with steel magnetic in the separated state that do not trigger; When upper loose-leaf and lower loose-leaf are subject to driving steel magnetic to move to housing inner chamber to the squeese pressure of housing inner chamber, described magnetic sensible switch and steel magnetic are near triggering state.
Principle of work of the present invention is as follows:
Material-level detecting device at right angle setting must be detected to material bit position in feed bin bulkhead or feed bin.In feed bin, material level is piled up while overflowing to detection position, flowing power and pressure-acting due to powder or particulate material, in promotion, loose-leaf and lower loose-leaf swing to housing inner chamber, the steel magnetic that makes to be fixed on loose-leaf or lower loose-leaf inner side approaches and is fixed on the magnetic sensible switch of housing inner chamber and excites high signal, by magnetic sensible switch, the high signal measuring is passed to electric-control system.And another loose-leaf being connected with the loose-leaf that steel magnetic is installed is also because of the flowing power of powder or particulate material and pressure-acting, to paste shell nozzle bottom crooked along the swaying direction of loose-leaf that steel magnetic is installed, thereby it is inner effectively to stop material to enter this material-level detecting device.
When in feed bin, material level drops to lower than this material-level detecting device, Action of Gravity Field due to the upper and lower loose-leaf itself on material-level detecting device, make upper and lower loose-leaf return to plumbness, thereby the steel magnetic that makes to be fixed on loose-leaf or lower loose-leaf inner side leaves and is fixed on the magnetic sensible switch of housing inner chamber and excites low level signal, by magnetic sensible switch, the low level signal measuring is passed to electric-control system.
The present invention compared with prior art, has the following advantages and effect:
1) use the present invention to detect material level signal stabilization, no longer there is the signal errors causing because of reasons such as the inner adsorbing powder dust of feed bin, a small amount of clouts, and effectively raise device signal accuracy rate, and obviously enhance productivity, for equipment, realize the production automation strong condition is provided;
2) simple in structure;
3) productive costs is low;
4) reliable, failure rate is low, maintenance is little;
5) easy to detect, control easily.
