Abstract
The utility model belongs to an infrared ray charge level detecting indicator to detect the charge level for a storage bin in feedstuff grain processing. Ordinary charge level indicator can not stand long-term press by material, and thereby, to cause out of control or damage. The utility model comprises a sealed infrared ray illuminator (1), an infrared ray receiver (2) and a display controller (3), and the utility model is characterized in that the infrared ray charge level detecting indicator cares nothing for material pressure and dust influence, and the utility model can work in the storage bin for a long time.
Description
The utility model relates to a kind of infrared ray level detector for detection powdery or granular material and is specially adapted to feed and grain processing industry, and material level in the feed bin is detected.
Level detector is a requisite detecting instrument in feed, the grain processing.Although existing multiple level detector occurs, but influence owing to material pressure in the feed bin and dust, cause the work that level detector can not be reliably and with long-term, as the diaphragm type level detector, it makes film produce deformation by the pressure of material to film, for the moving contact output signal, this level detector follows the string easily owing to pressed by material for a long time, causes damage.Other plants main rotating level detector, and motor is worked under stall for a long time, and not only power consumption is bigger, and in the impact process of blanking, and its blade is very fragile and burn motor.As for the tuning-fork type level detector,, make it the tuning fork distortion, thereby lose detectability along with the long-term impact of material.Weight tracking mode level detector, not only the hammer phenomenon also often appears burying in complex structure, can't follow the tracks of detection to making, above-mentioned level detector, its ultimate principle are to utilize to detect original paper, are being subjected under the material institute pressure situation, produce deformation, stop vibration, or displacement comes material is detected.Under long-term and big pressure, they are to be difficult to accomplish work steady in a long-term like this.
For making the work of level detector long-term stability, level detector self should be afraid of long-term pressure, and this is difficult to accomplish to above-mentioned level detector in one's power.
The purpose of this utility model provides and a kind ofly unfavorablely produces distortion or motion and the novel level detector of output signal in material with level detector, and it can stand the long-term big pressure of material.
The utility model is to realize like this.Detect for last material level, an infrared light emission device is installed in the position that feed bin will detect, at infrared receiver of the suitable distance installation of distance infrared light emission device, the infrared ray that sends in order to the receiving infrared-ray illuminator.Like this, along with material enters from material outlet, when the material of piling up rises to the infrared ray that its infrared light emission device is sent and blocks, after infrared receiver just can not receive infrared ray, send signal immediately, thereby know the height (or position) of material, for blanking bin, then work together, just the opposite.Electronic circuit in infrared light emission device and the infrared receiver then is contained in the seal that the shell made by metal or plastics and lens form, and material is long-term does not press so it is afraid of.Remove this, this infrared ray level detector is contained in the material stream passed place in the feed bin.Its lens are washed away by material, and infrared ray has very high penetration power again, and this has just determined steady operation under its place dust state.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
This infrared ray level detector is seen accompanying drawing 1, comprises that one is infrared light emission device (1), infrared receiver (2) and display controller (3) composition of sealing to feed bin.Infrared light emission device (1) is made up of skirt (4), shell (5), printed circuit board (PCB) (6), infrared light emission pipe (7), dustproof cushion rubber (8), dead ring (9) and lens (10).Printed circuit board (PCB) (6) is welded with electronic original part, and its power supply is then drawn through skirt (4) by lead and is connected on the display controller (3).Infrared receiver (2) then is made up of lens (11), the dustproof cushion rubber (13) of dead ring (12), photoelectric cell (14), printed circuit board (PCB) (15), shell (16) and skirt (17), printed circuit board (PCB) is welded with electronic original part on (15), and its power supply and signal are then drawn through skirt (17) by lead and be connected on the display controller (3).Among this embodiment, infrared light emission pipe (7) is outwards launched the recurrent pulse that dutycycle is 1:40～1:60, through lens (10) it is become the lens (11) of parallel beam directive infrared receiver (2), and the directional light that lens (11) will be penetrated focuses on the photoelectric cell (14), convert thereof into electric signal, on display controller (3), send light and voice signal.
Claims (4)
1, a kind of in order to detect the infrared ray level detector of powder shape, granular material, this level detector is made up of infrared light emission device (1), infrared receiver (2) and display controller (3), it is characterized in that infrared light emission device (1) and infrared receiver (2) seal fully to material, the infrared ray that infrared light emission device (1) sends is scioptics (10) directive infrared receivers (2).Infrared receiver (2) then receiving infrared-ray illuminator (1) is penetrated next infrared ray, and scioptics (11) are mapped on the photoelectric cell (14), convert thereof into electric signal.
2, level detector according to claim 1, it is characterized in that infrared light emission device (1) comprises skirt (4), shell (5), printed circuit board (PCB) (6), infrared light emission pipe (7), dustproof cushion rubber (8), tight loop (9) and lens (10) composition.
3, level detector according to claim 1, it is characterized in that infrared receiver (2) comprises lens (11), dead ring (12), dustproof cushion rubber (13), photoelectric cell (14), printed circuit board (PCB) (15), shell (16) and skirt (17) composition.
4, according to claim 1 and 2 described level detectors, infrared light emission device (1) the outwards infrared ray of emission is characterized in that the recurrent pulse parallel rays of dutycycle 1:40～1:60.
