Description
Technical field
The utility model relates to control technology field, thing position, particularly relates to a kind of mechanical type material bit switch that can detect uncovered, the airtight and Pressure Vessel in industrial processes, the material level in feed bin and control.
Background technology
Anti-rotation type material level switch is a kind of device adopting the mode of mechanical rotation to monitor material level, and usually using micro motor as drive unit, transmission shaft is connected with clutch coupling, and axle head is with blade; When material level does not touch material lower than blade, blade, blade rotates under the drive of motor; When material level raise, touch blade time, pick-up unit exports a contact point signal, cuts off the electricity supply simultaneously and blade is stopped operating; When material declines, resistance suffered by blade disappears, and pick-up unit relies on torque spring to return to virgin state again, and blade recovers to rotate.For the material of different specific weight, torque magnitude can regulate.
Contour compared with capacitance charge level switch in the reliability theory of mechanical type material bit switch, but find in actual applications, if in feed bin, dust concentration is large, grain graininess is thin, fine grained easily enters into the gap place of transmission shaft and makes transmission shaft generation stucking phenomena, transmission shaft provides false alarm signal because rotating, and causes monitoring material position malfunctioning.In addition, existing mechanical type material bit switch cannot see instrument mode at the scene intuitively.
Utility model content
The utility model, for the problems referred to above weak point, provides a kind of mechanical type material bit switch, and its antiseize performance is better, work is more reliable, it is more accurate to measure and applicability is wider.
The technical solution of the utility model is achieved in that
A kind of mechanical type material bit switch, it comprises housing, micromachine, microswitch, transmission shaft and detects blade, micromachine and microswitch is provided with in described housing, micromachine is in hull outside one end by adapter sleeve connection for transmission axle, and the other end of transmission shaft connects detection blade by back-moving spring; Described housing is also provided with high brightness dichromatism status indicator lamp, this high brightness dichromatism status indicator lamp indicates connection terminal to be connected with the state in housing.
Preferably, also extension lever is connected with between described adapter sleeve and transmission shaft.
Preferably, connecing the pivot angle detecting blade described in is 25-35 °.
Stuff level switch of the present utility model belongs to electromechanical integration instrument, and its outstanding feature is the sealing of Product checking part and the band lamp display of detecting unit housing parts.Strictly isolate between instrument detecting portion and instrument travelling mechanism, feed bin dust can not enter body, has good high temperature resistant, dust-proof, anticorrosion, shock-resistant and withstand voltage properties; Housing has the bi-colour LED of instrument running status intuitively, user can see instrument mode easily at the scene intuitively, thus learns material level situation in feed bin.Instrument structure is simple, and without numerous and diverse electric wiring, running is very reliable, need not debug after installation, is easy to safeguard, not affected by environment, can long-time running continuously.Be applicable to the wide spectrums such as iron and steel, metallurgy, cement, rubber, chemical fibre, electric power, grain.
Accompanying drawing explanation
Fig. 1 is the first exemplary construction schematic diagram of the present utility model;
Fig. 2 is the second exemplary construction schematic diagram of the present utility model.
In figure: 1, housing; 2, adapter sleeve; 3, back-moving spring; 4, blade is detected; 5, transmission shaft; 6, extension lever.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Example 1
As shown in Figure 1, a kind of mechanical type material bit switch, it comprises housing 1, micromachine, microswitch, transmission shaft 5 and detects blade 4, micromachine and microswitch is provided with in described housing 1, micromachine is by one end of adapter sleeve 2 connection for transmission axle 5 outside housing 1, and the other end of transmission shaft 5 connects by back-moving spring 3 a slice detection blade 4 that pivot angle is 25-35 °; Described housing 1 is also provided with high brightness dichromatism status indicator lamp, this high brightness dichromatism status indicator lamp indicates connection terminal to be connected with the state in housing 1.
Principle of work: micromachine drives the detection blade 4 in feed bin to rotate by transmission shaft 5, when material arrives and measures and detect blade 4 position, prevention is detected blade 4 to rotate, micromachine in housing 1 hangs, produce reaction torque and act on microswitch output signal, make micromachine stall simultaneously.When material decline detection blade 4 is released, back-moving spring 3 is withdrawn into working position micromachine, and initial position got back to by microswitch, and contact output signal is closed.Housing 1 has the high brightness dichromatism status indicator lamp of instrument intuitively, user can see instrument mode easily at the scene intuitively, thus learns material level situation in feed bin.This example 1 is suitable for level and is installed on the side arm of feed bin.
Example 2
As shown in Figure 2, measuring needs, between adapter sleeve 2 and transmission shaft 5, being also connected with extension lever 6 to meet feed bin top, in addition, detecting blade 4 is symmetrical two panels, and other structures are identical with example 1, therefore omits.The principle of work of example 2 is also identical with example 1, therefore omits.
