Description
Technical field
The utility model relates to a kind of stuff level switch, relates in particular to a kind of high temperature resistant shock resistance resistance and revolves stuff level switch.
Background technology
Stuff level switch is mainly used in the effect that shows that material level is put in the feed bin, so stuff level switch requires to have reliability height, long service life characteristics.The blocking rotary type stuff level switch of using at present impacts at high temperature, lump material, use in the environment of dust, therefore need its have than mill run more superior high temperature resistant, do impacts, prevent dust and self-cleaning performance.
The utility model content
The purpose of the utility model be to design a kind of high temperature resistant, do impact, stuff level switch is revolved in dustproof and automatically cleaning resistance; Make it have the advantages that stuff level switch is revolved in common resistance; And can have better high temperature resistant, do impact, dustproof and self-cleaning function, can use having under the bad working environments such as high temperature, piece material, dust.And can use through external circuit and industrial PLC, DCS and electric control loop, can accurately send the material level shows signal, can control the start and stop control of feeder apparatus or blowing equipment again, reach the demand of modern automation production and management.
The utility model adopts following technical scheme to realize:
Stuff level switch is revolved in high temperature resistant shock resistance resistance, in mounting bracket, utilizes bearing to drive transmission shaft 6, and the mounting bracket left end connects cover body 14, and right-hand member connects sheath 10; The left end of transmission shaft 6 is connected with cover body 14 interior micromachines 4, and the right-hand member of transmission shaft is connected with foil detector 13; Establish microswitch 3, spring 18 and wiring board 1 in the cover body 14, it is characterized in that: the two ends of flange-cooled cylindrical shell 8 are provided with the labyrinth and prevent dust 11 for no oily left bearing 7 and no oily right bearing 9 in the sheath 10, and the sealed port bottom of sheath 10 is provided with ash discharging hole 12.
Further, transmission shaft 6 is positioned at sheath 10.
Further, wiring board 1 is established the time delayed signal circuit.
The utility model has the advantages that: adopt the novel designs scheme; Make the product more can be high temperature resistant; The impact of anti-material, labyrinth dedusting and self-cleaning function in the dust atmosphere can adapt to the feed bin of various materials; And can be in lump material, high fall impact, streams power, dust atmosphere reliability service, effect is more superior.
Description of drawings
Fig. 1 is the structural drawing of the utility model.
Embodiment
Shown in figure one: stuff level switch mainly is made up of wiring board 1, motor rotatable lamella 2, microswitch 3, micromachine 4, unitor 5, transmission shaft 6, no oily left end bearing 7, flange-cooled cylindrical shell 8, no oily right-hand member bearing 9, sheath 10, labyrinth dedusting 11, ash discharging hole 12, foil detector 13, cover body 14, first flange 15, cylindrical shell 16, second flange 17, and wherein micromachine 4, microswitch 3, spring 18 and wiring board 1 are formed electric control system.
Sheath 10 can prevent that the stops material directly impacts transmission shaft 6, does not have oily left bearing 7 and constitutes stronger physical strength with no oily right bearing 9 and transmission shaft 6, the power of generation and to the influence of electrical control part when overcoming material and flowing downward.Labyrinth dustproof 11 makes the dust settling that gets in the sheath, and discharges from ash discharging hole 12, plays automatic cleaning action.
Do not have oily left bearing 7 and adopt oilless bearing,, overcome lubricating oil at high temperature degradation and charing to adapt to worst hot case with no oily right bearing 9.Transmission shaft 6 adopts high temperature resistant steel processing and fabricating with sheath 10, prevents mechanical deformation under the high temperature.
When wherein 13 detections of detection sheet are to the material position; Transmission shaft 6 is delivered to micromachine 4 through unitor 5; Micromachine 4 drives motor rotatable lamella 2 and touches microswitch 3 disconnections; As control signal or shows signal, charge level is in more than the sensing point in the expression storehouse signal output for microswitch signal cut micromachine 4 power supplys, wiring board 1.When charge level is reduced to detecting plate when following; Spring pulling motor rotatable lamella 2 lets microswitch 3 reset to be in closure state; Micromachine 4 begin to rotate after electric; Microswitch 3 signals are exported signal as control signal or shows signal through wiring board 1, and expression feed bin material charge level is in below the sensing point.The output signal can be through auxiliary reclay or direct and PLC, DCS or control loop, the start and stop of control conveying equipment.
