Field.
Background technique
Hammer mill is a kind of equipment with impulse form broken material, is divided to single rotor and birotor two kinds of forms.It is
The material that maximum particle size is 600-1800 millimeters is directly crushed to 25 or 25 millimeters of single stage crushing crushers below.Hammer
Crusher is suitable in industrial departments such as cement, chemical industry, electric power, metallurgy being crushed medium-hard material, as lime stone, clinker,
Operation broken and fine crushing in the materials such as coke, coal.In actual use, after a period of work, tup has crusher
Different degrees of abrasion causes material percentage of damage low, at this time with regard to the tup for needing to renew, but since tup abrasion is not easy to examine
Feel, leads to not in time replace tup.
Summary of the invention
To solve technical problem of the existing technology, the present invention provides a kind of structure is simple, easy to detect, Neng Gouzhun
Really judge whether tup wears up to the limit, accuracy high hammer head of hammer crusher wear abrasion alarming device and its alarm method.
To achieve the above object, the technical scheme adopted by the invention is as follows a kind of hammer head of hammer crusher abrasion alarm dress
It sets, including hammer mill and tup, extreme position test point is provided on each tup, the hammer mill
Multiple groups mounting hole is provided on apron plate, mounting hole described in every group is separately positioned on the top of the apron plate of hammer mill under
Portion is separately installed with photoelectric sensor transmitting terminal and photoelectric sensor receiving end, the photoelectric sensor hair in the mounting hole
It penetrates end and photoelectric sensor receiving end to pass through mounting base respectively and be fixed in mounting hole, gas blow pipe is installed in the mounting base,
The photoelectric sensor transmitting terminal and photoelectric sensor receiving end to rays diameter and the tup upper limit position test point
Circus movement trajectory tangential, the gas blow pipe are used to dispel the powder on photoelectric sensor transmitting terminal and photoelectric sensor receiving end
Dirt, the gas blow pipe are connected by tracheae with high pressure gas holder, and control valve, the photoelectric sensor hair are equipped on the tracheae
It penetrates end, photoelectric sensor receiving end and control valve to be connected with controller, timing circuit built in the controller, and controller
On be connected with combined aural and visual alarm.
Preferably, there are two extreme position test points for setting on each tup, and installation hole number described in every group is four
It is a, it is respectively used to two pairs of photoelectric sensor transmitting terminals of installation and photoelectric sensor receiving end.
A kind of hammer head of hammer crusher abrasion alarm method, including above-mentioned warning device, follow the steps below operation,
In crusher idle running, the corresponding photoelectric sensor transmitting terminal of every group of tup sends optical telecommunications to photoelectric sensor receiving end
Number, the controller acquires the photosignal of each photoelectric sensor transmitting terminal and photoelectric sensor receiving end, due to tup
It blocks, photosignal lacks, and the controller calculates the missing time that each tup causes the photosignal, the photoelectricity
The missing time of signal is equal to what each tup blocked photosignal to terminating from starting to block photosignal
Run duration；When tup is normal, the missing time of the photosignal is a；When tup is worn, the photosignal
Missing time be b, and b < a;When tup wears up to extreme position or fractures, the missing time of the photosignal is 0, then
Controller is alarmed by combined aural and visual alarm.
Preferably, by the way that a limit test point is respectively arranged in the two sides of tup, pass through two limit test points of acquisition
The signal deletion time judges that the abrasion of that side of tup than more serious, and is alarmed.
Compared with prior art, the present invention has following technical effect that the configuration of the present invention is simple, easy to use, using
Be equipped on the apron plate of hammer mill for the photoelectric sensor penetrated, using the movement of each tup to photoelectric sensor into
Row blocks, and causes signal deletion, calculates the missing time of the signal, so that it is determined that whether tup wears up to extreme position, in time
It alarms, prompts replacement, using simple, need to only be detected in idle running, accuracy rate is high.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 be in the present invention photoelectric sensor to penetrating schematic diagram.
Fig. 3 is the schematic diagram of tup extreme position test point in the present invention.
Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Accompanying drawings and embodiments are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
Such as a kind of hammer head of hammer crusher wear abrasion alarming device of Fig. 1 to Fig. 3, including hammer mill 1 and tup 2, each
It is provided with extreme position test point 3 on tup 2, multiple groups mounting hole 4, every group of peace are provided on the apron plate of hammer mill 1
Dress hole 4 is separately positioned on the upper and lower part of the apron plate of hammer mill, and photoelectric sensor hair is separately installed in mounting hole 4
End 5 and photoelectric sensor receiving end 6 are penetrated, photoelectric sensor transmitting terminal 5 and photoelectric sensor receiving end 6 pass through mounting base 7 respectively
It is fixed in mounting hole 4, gas blow pipe 8 is installed in mounting base 7, photoelectric sensor transmitting terminal 5 and photoelectric sensor receiving end 6
To the circus movement trajectory tangential of rays diameter and tup upper limit position test point, gas blow pipe 8 is for dispelling photoelectric sensor hair
The dust on end 5 and photoelectric sensor receiving end 6 is penetrated, gas blow pipe 8 is connected with high pressure gas holder 10 by tracheae 9, is pacified on tracheae 9
Equipped with control valve 11, photoelectric sensor transmitting terminal 5, photoelectric sensor receiving end 6 and control valve 11 are connected with controller 12,
Timing circuit built in controller 12, and combined aural and visual alarm 13 is connected on controller 12.
In the use of the present invention, in one or two extreme position test point of the upper selection of tup, then according to limit position
Set the location arrangements photoelectric sensor of test point to position is penetrated, during rotation can be to the letter of photoelectric sensor using tup
It number is blocked, leads to signal interruption, by the time of signal interruption, judge whether tup wears.
For installing five tups on turntable, in crusher idle running, photoelectric sensor transmitting terminal is to photoelectric sensing
Device receiving end sends photosignal, and controller acquires the optical telecommunications of each photoelectric sensor transmitting terminal and photoelectric sensor receiving end
Number, due to blocking for tup, photosignal is lacked, and controller calculates each tup when causing the missing of the photosignal
Between, the missing time of photosignal is equal to each tup from starting to block photosignal to end to photosignal progress
The run duration blocked；When tup is normal, the missing time that controller collects five photosignals is a1 、a2、a3 、a4、
a5；When tup is worn, the missing time of photosignal is b1 、b2、b3 、b4、b5, and b1 、b2、b3 、b4、b5< a1 、
a2、a3 、a4、a5;When tup wears up to extreme position or fractures, the missing time of photosignal is 0, then controller passes through sound
Light crossing-signal is alarmed.
In addition, by the way that a limit test point is respectively arranged in the two sides of tup, by the letter for acquiring two limit test points
Number missing time judges that the abrasion of that side of tup than more serious, and is alarmed.
