Description
Technical field
The present invention relates to a kind of material detection device, more particularly to a kind of material-level detecting device, be suitable for powder and
The material-level measure of pellet, belongs to material detection device field.
Background technology
During powder and particulate material reservoir and Automatic Conveying, it is required for that material-level detecting device is installed, so as to obtain
State of the material in container, realizes that monitoring material position and system automation are controlled with this detection information.Current material-level measure dress
Put and be substantially using optoelectronic switch or proximity switch etc., but used during powder and particulate material reservoir and Automatic Conveying
Optoelectronic switch and proximity switch, easily because the dust of feed bin inner chamber covers unrestrained or material sticks test surface and caused by signal slip up.
The content 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 is in detectable substance
It will not be overflow during material material position by dust or a small amount of material and cover and influence signal.
The purpose of the present invention is achieved by the following technical programs：
A kind of material-level detecting device, it is characterised in that：It includes housing, upper loose-leaf, lower loose-leaf, magnetic sensible switch and steel magnetic；
One lateral opening of the housing；The upper loose-leaf and lower loose-leaf are movably set in the shell nozzle and to the housing
Buffer action is played inside and outside opening, the upper loose-leaf top is rotatably connected to the top of the shell nozzle, the upper work
Page bottom is connected with the lower loose-leaf top by hinge, and the bottom of the lower loose-leaf is freely buckled in the shell nozzle
Basolateral, the bottom of the shell nozzle is additionally provided with the inclined-plane for being easy to the bottom of lower loose-leaf inwardly to slide；The magnetic sensible switch
It is fixedly installed in the enclosure interior；The steel is magnetically fixed to be arranged on the inside of upper loose-leaf or lower loose-leaf；When upper loose-leaf and lower loose-leaf
It is not affected by the extruding force of housing cavity when keeping naturally drooping state under Gravitative Loads, magnetic sensible switch and steel magnetic are in point
From non-triggering state；When upper loose-leaf and lower loose-leaf are driven steel magnetic to be moved to housing cavity by the extruding force to housing cavity
When, the magnetic sensible switch is in close to triggering state with steel magnetic.
The operation principle of the present invention is as follows：
Material-level detecting device, which is installed vertically in feed bin bulkhead or feed bin, must detect the position of material position.When material position in feed bin
Accumulation is when overflowing test position, because the mobility and pressure of powder or particulate material are acted on, and loose-leaf and lower loose-leaf are to shell in promotion
Intracoelomic cavity is swung, and is made to be fixed on the steel magnetic on the inside of loose-leaf or lower loose-leaf and is excited close to the magnetic sensible switch for being fixed on housing cavity
High signal, electric-control system is passed to by magnetic sensible switch by the high signal measured.And with being provided with what the loose-leaf of steel magnetic was connected
Another loose-leaf is also because the mobility and pressure of powder or particulate material are acted on close to shell nozzle bottom along the work for being provided with steel magnetic
The swaying direction bending of page, so as to effectively prevent material from entering inside this material-level detecting device.
When material position drops below this material-level detecting device in feed bin, due to the upper and lower loose-leaf on material-level detecting device
The Action of Gravity Field of itself, makes upper and lower loose-leaf return to plumbness, so that being fixed on the steel magnetic on the inside of loose-leaf or lower loose-leaf
Leave the magnetic sensible switch for being fixed on housing cavity and excite low level signal, the low level signal measured is passed into electricity by magnetic sensible switch
Control system.
The present invention compared with prior art, with advantages below and effect：
1) it is stable using present invention detection level signals, no longer occur because of the original such as adsorbing powder dust, a small amount of clout inside feed bin
The signal errors caused by, and effectively raise device signal accuracy, hence it is evident that production efficiency is improved, is that equipment realizes production
Automation provides strong condition；
2) it is simple in construction；
3) production cost is low；
4) reliable, fault rate is low, and maintenance is small；
5) easy to detect, control is easy.
