Abstract
The utility model relates to a material position controlling probe, which is composed of a probe outer shell, a suspension arm, a movable pole, a copper ring, a plastic support stand, etc. The material position controlling probe is characterized in that the movable pole made of rod-shaped metals is suspended at the center of the copper ring of a static pole composed of the plastic support stand and the copper ring. The copper ring and the movable pole are respectively connected with external display screen lines by wires. Because of the push of material, a probe suspended in a bin generates slant; owning to the function of earth gravity, the movable pole contacts to the copper ring which forms the static pole, which enables the node of a display circuit to close; output signals display and indicate the conditions of a hopper.
Description
The utility model relates to a kind of material level control probe.
In production practices, common way with the control volume is controlled the weighing and proportioning of storeroom, and in the coal washery coal bunker of seeing at present as us, capacitance probe commonly used is controlled the following coal amount in the feed bin.Though this capacitance probe that passes through usefulness has certain positive role, in use can see the defective and the deficiency of its existence.Its obvious defects is in this comparatively abominable conveying environment of coal bunker, because the factors vary of aspects such as humidity, dust, temperature variation is under some influence the reliability of probe.
The purpose of the present utility model is to provide a kind of simple in structure, indication reliability height, is subjected to environmental change to influence little material level control probe.
This material level control probe comprises compositions such as probing shell 1, hanger bar 2, moving limit 3, copper ring 4, plastic stent 5, it is characterized in that described hanger bar 2 is spirally connected with probing shell 1 top, the quiet limit of being made up of the copper ring 4 on plastic stent 5 and solid and its top is being set on the probing shell base under the hanger bar 2, described moving limit 3 is a metal bar, and is suspended from the quiet limit of ring-type center; All there is lead to link to each other on the top copper ring 4 of described moving limit 3 and quiet limit simultaneously with external circuit.
According to the material level control probe that above design proposal is made, to compare with electric capacity rope formula material level control probe commonly used at present, its advantage is to be subjected to environmental change to influence little, indication reliability height.
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is user mode figure of the present utility model.
Further describe the utility model below in conjunction with accompanying drawing, and provide embodiment.
Among the figure: 1, probing shell 2, hanger bar 3, moving limit 4, copper ring 5, plastic stent.
This material level control probe is applicable to the usefulness that the solid material volume in hopper or the feed bin is quantitatively controlled.Inner bottom part at its probing shell 1 is provided with a copper ring 4 by plastic stent 5 support fixation; The hanger bar 2 that is being spirally connected on the top of probing shell 1, the center tandem arrangement of this hanger bar 2 lead that links to each other with extraneous pulpit display screen, on the support of lead, is hanging the moving limit 3 that stretches into copper ring 4; Should moving limit make by metal material; All be connected on described moving limit 3 and the copper ring 4 with the external cable lead.
In actual use, this probe is hung in the feed bin, when rising gradually, material is higher than probe during suspension height, because pushing of material makes the run-off the straight of suspension probe, because gravitational effect makes limit 3 contact with the copper ring 4 of forming quiet limit, make the node closure of display circuit, output signal makes and shows indication hopper situation.
Claims (1)
1, a kind of material level control probe is made up of probing shell (1), hanger bar (2), moving limit (3), copper ring (4), plastic stent (5), it is characterized in that described hanger bar (2) and probing shell (1) top are spirally connected, the quiet limit of being made up of the copper ring (4) on plastic stent (5) and solid and its top is being set on the probing shell base under the hanger bar (2); Described moving limit (3) is a metal bar, and is suspended from the center of the quiet limit of ring-type; All there is lead to link to each other on described moving limit (3) and the quiet limit top copper ring (4) simultaneously with external circuit.
