Description

Multiple spot continous way on-line vibration sieve amplitude detecting appearance
Technical field
The utility model relates to the adjustment technology field of industrial vibratory screening apparatus, relates in particular to industrial vibratory screening apparatus amplitude detecting technical field.
Background technology
Current; Industrial vibration sieve use field is extensive; The screening of raw material such as colliery, mine all needs vibratory screening apparatus to accomplish, and amplitude is the important technology index in the vibratory screening apparatus manufacturing process, and it directly has influence on the screening efficiency of vibratory screening apparatus and to raw-material screening quality.
The amplitude detecting method that present stage adopts generally has two kinds: a kind of is easy groove method, utilizes groove through the visual inspection amplitude, and precision is lower; Another kind method is to adopt the hand-held amplitude measuring instrument; In the vibratory screening apparatus running, carry out the detection of amplitude; Though this method detection method degree of accuracy is very high, the position and the numerical value that need detect owing to a vibratory screening apparatus are a lot, need back and forth constantly to change check point; Obtaining total data, thereby very inconvenience.For the enterprise that makes vibratory screening apparatus, though second kind of way precision is higher, for the amplitude of detection vibratory screening apparatus, adjust and reach final designing requirement and just seem pretty troublesome.In addition, in the process of amplitude adjustment, the variation of a point can have influence on the amplitude of other several points simultaneously.So, preferably detect 10 points simultaneously, like this, need 10 such instruments, investment is big, and is loaded down with trivial details and not directly perceived.
The utility model content
The purpose of the utility model is to provide a kind of multiple spot continous way on-line vibration sieve amplitude detecting appearance, and is simple in structure, be convenient to install, and confirms the position of amplitude adjustment, increase and decrease counterweight fast, and image data is continuous, but recording storage.
For reaching said purpose, the utility model discloses a kind of multiple spot continous way on-line vibration sieve amplitude detecting appearance, comprise detecting unit, signal sampler, control system, it is characterized in that:
Vibratory screening apparatus compass screen surface both sides are provided with a pair of detecting unit to collect the compass screen surface amplitude signal;
After the signal collection that signal sampler is collected every pair of detecting unit is handled, transfer to control system;
Control system comprises industrial computer, the printer of being with display screen.
Preferably, said detecting unit is the magnetic force amplitude sensor.
Preferably, said signal sampler is 16 passage vibration signals collecting appearance.
Through said structure, the multiple spot continous way on-line vibration of the utility model sieve amplitude detecting appearance is realized following technique effect:
(1) simple in structure, be convenient to install; Detecting unit is arranged on compass screen surface relevant position on the vibratory screening apparatus sidewall, just can accomplishes installation;
(2) position of definite fast amplitude adjustment, increase and decrease counterweight; The signal that signal sampler is collected detecting unit is passed to industrial computer, is handled by industrial computer, can confirm the position of amplitude adjustment, increase and decrease counterweight fast;
(3) image data is continuous, stored record; Gather at detecting unit per minute interval once, and industrial computer is stored data and curve plotting figure when handling;
(4) detect whether there is mechanical fault; The utility model reflects whether there is mechanical fault through the electric current that detects shaker vibration source motor.
The detailed content of the utility model can through after explanation and the institute's accompanying drawing stated obtain.
Description of drawings
Fig. 1 is the utility model circuit diagram.
Embodiment
Below in conjunction with accompanying drawing, the preferred embodiment of the utility model is described further.
Shown in accompanying drawing 1, the utility model discloses a kind of multiple spot continous way on-line vibration sieve amplitude detecting appearance, comprise detecting unit, signal sampler, control system, it is characterized in that:
Vibratory screening apparatus compass screen surface both sides are provided with a pair of detecting unit to collect the compass screen surface amplitude signal;
After the signal collection that signal sampler is collected every pair of detecting unit is handled, transfer to control system;
Control system comprises industrial computer, the printer of being with display screen.
Detecting unit described in the present embodiment is the magnetic force amplitude sensor.
Signal sampler described in the present embodiment is 16 passage vibration signals collecting appearance.
In the actual production, vibratory screening apparatus is after the structure manufacturing is accomplished, and most important operation is the test and the adjustment of amplitude; The amplitude that reaches designing requirement can satisfy the requirement of production run output and quality; The whole machine body structure is not produced destructive influences; Particularly,, just stricter to the requirement of amplitude owing to vibratory screening apparatus is installed on 20 meters high structural members for the pitch facilities of mix storied building.Otherwise excessive amplitude can produce harmful effect to whole building body.
Because structural member is made the error in the assembling process, the amplitude of every vibratory screening apparatus is different in different positions, so, adjust after tested, make it reach the value range of designing requirement.When adjusting at some, the amplitude of other diverse location point will be followed and done corresponding variation in adjustment, and what originally adopt is the mode of spot measurement; Can not reflect the variation of other points intuitively, make troubles for debugging work, repetitive work is a lot; After adopting the multiple spot continuous coverage, can see very intuitively that turn-off far away begins to this change procedure of stabilized amplitude, and through planning as a whole adjusting; Debug time is significantly reduced, and the adjustment precision significantly improves.
Present embodiment is selected state-of-the-art 16 passage vibration signals collecting appearance and magnetic force vibration transducer for use; Through signal sampler computing machine is handled and be uploaded to the vibration signal of each passage; Through relevant process software; On the display screen of computer, demonstrate the vibrating numerical of every bit, simultaneously, according to per minute once the interval image data and store and the figure that runs a curve.Its automatic recording storage and preservation are no less than 48 hours vibration data.In addition, the utility model also shows the electric current of shaker vibration source motor, thereby can reflect whether there is mechanical fault.The utility model is applied to the test in the production debugging of vibratory screening apparatus, can debug time be reduced to 1/8 of original spot measurement, and efficient increases substantially.
It is obvious that, and above description and record only are to give an example rather than disclosure, application or use in order to limit the utility model.Though described and be described in the drawings embodiment in an embodiment; But the optimal mode that the utility model does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present is with the specific examples of the instruction of implementing the utility model, and the scope of the utility model will comprise any embodiment of the instructions that falls into the front and appended claim.
