Technical field
One kind swollen tripe detection means of point interconnection system multi-compartment tube grinding machine and pre-swollen tripe regulation and control method, are related to tube mill detection means
And technical field.
Background technology
Tube mill is fine grinding equipment critically important in the modern industry, is widely used in building materials, metallurgy, ore dressing, electric power and chemical industry
Industry grinding production field.Large-scale tube mill typically has multiple bins, and its production capacity is very high, when with partition panel by grinding mill barrel
When being divided into the bin of two, three or four different lengths, referred to as multi-compartment tube grinding machine.The multi-compartment tube grinding machine ground different with short bobbin grinding machine
Side is only that its length diameter group is big 2-7 times, and the time that material undergoes in tube mill is longer, and product fineness is uniform, crushes
It is bigger.In multi-compartment tube grinding machine, grinding mill barrel is separated into some bins by partition panel, thin according to material in each storehouse
Mill situation coordinates abrasive body, the fine grinding of material is carried out stage by stage by storehouse, thus obtains higher grinding efficiency.
In tube mill production process, most important failure is exactly swollen tripe phenomenon, tube mill is swollen tripe, is referred to because certain is former
Cause(Such as sand return amount is big, raw ore quantitative change is big)Make the material quantitative change for feeding tube mill big, exceeded tube mill allows most in itself
Big handling capacity and do not arrange not come out, the amount for discharging tube mill is less than the inventory into tube mill, mineral aggregate in tube mill by
Gradually accumulate, tube mill is lost ore grinding effect, this phenomenon is referred to as the swollen tripe of tube mill.The harm of tube mill is swollen tripe is very big,
Swollen tripe not only loses tube mill(Or reduce)Milling action to ore, the steady operation of ore grinding is destroyed, and handled swollen
Tripe will also cause the fluctuation of feed ore concentration and fineness to subsequent job, have impact on being normally carried out for subsequent job;It is in addition, serious swollen
Tripe can cause tube mill, ore feeder, sand return case, bearing, gear etc. to be hit load and damage.After tube mill is swollen tripe, typically adopt
Take and stop mineral aggregate supply, increase and handled to the mode of mineral water, when swollen tripe phenomenon than it is more serious when, also to use water under high pressure,
It is artificial to unload the more complicated modes such as mill.Swollen tripe phenomenon has had a strong impact on the production efficiency of tube mill.And if design is a kind of swollen
Tripe detection means, detection of the tube mill before swollen tripe is realized, and factually show the real-time adjustment of tube mill work according to testing number, made
Pre-swollen tripe state of the tube mill real-time working in swollen tripe early stage, the then it is possible to prevente effectively from generation of the swollen tripe failure of tube mill, ensures
Tube mill normal operation, the maximization of tube mill operating efficiency is realized, realize industry energy conservation consumption reduction purpose.

Dress is convenient, without the connection of complexity, simplifies package unit installation procedure, and is rotated without prejudice to tube mill, is to ensure tube mill
The smoothly key device of operating and transmission signal.
It is a kind of to carry out pre-swollen tripe regulation and control method, including following step using the swollen tripe detection means of point interconnection system multi-compartment tube grinding machine
Suddenly:
The first step, equipment installation:Tube mill is installed to operating position, the installation detecting device in the detection mouth of tube mill;
Second step, simulation tube mill work and demarcate the swollen tripe state of tube mill, draw detector under the swollen tripe state of tube mill
The time T0 being in material:A small amount of ballstone is added to tube mill inside, starts variable-frequency motor and drives tube mill with normal work
Speed rotates, and starts mineral aggregate belt conveyor with normal work speed to tube mill delivered inside material, makes tube mill normal work,
Meanwhile operator's personal monitoring's tube mill internal state, mineral aggregate belt conveyor speed is improved if normal operation, mineral aggregate is improved and adds
Acceleration, continue to monitor, until tube mill any of which bin enters swollen tripe state, the detector recorded in each bin is in
Time T0 in material, then T0 is that detector is in material when swollen tripe state occurs when the tube mill is grinding the material
In time;
3rd step, normal work, and rotate a circle the signal of output to tube mill and the time is gathered in real time, record is each
Detector in individual bin is in the time T in material respectively;
4th step, according to T data regulate and control tube mill pre-swollen tripe state operate:It is anti-that control system receives signal processing module
The data signal of feedback, and judge digital time length T, according to time T numerical values recited, send command adapted thereto control mineral aggregate
Belt conveyor and blower fan work, tube mill is set to keep the operating of pre-swollen tripe state.
Any bin enters the method for swollen tripe state including mainly including following several inside operator personal monitoring tube mill
Individual aspect:
1), tube mill Main motor current table indicator current constantly declining;
2), tube mill operating sound it is dull, noise diminishes, and does not almost hear the impact of steel ball with rushing down the sound fallen;
3), tube mill there is ore pulp outwards to overflow to ore deposit end;
4), outlet mineral aggregate start thicker, sand return amount is being gradually increased, and effluent concentration increase, granularity are thicker;
5), flotation froth have a significant change, floating agent effect imbalance, mineralising phenomenon weakens etc..
It is described to regulate and control tube mill according to time T data and be in the method that pre-swollen tripe state operates:
1), when all bins in tube mill time T numerical value be less than the bin T0*80% when, tube mill is less than pre-swollen tripe
State is run, and control system sends instruction, is progressively increased the speed of service of blower fan and mineral aggregate belt conveyor, is progressively increased the first storehouse
The mineral aggregate input of room;
2), when any bin in tube mill time T numerical value be equal to the bin T0*80% when, tube mill keep pre-swollen tripe
State is run, and control system sends instruction, rotation speed of fan is kept stable, and the speed of mineral aggregate travelling belt keeps stable;
3), when any bin in tube mill time T numerical value be more than the bin T0*80% when, tube mill break through pre-swollen tripe
State control system sends instruction, reduces the speed of mineral aggregate travelling belt, gradually reduces the mineral aggregate input quantity of bin, and keep wind
Machine rotating speed is constant;
4), when any bin in tube mill time T numerical value be more than the bin T0*90% when, tube mill will enter swollen
Tripe state, control system control blower fan is rotated with maximal rate, while stops the operation of mineral aggregate travelling belt, stops the first bin
Mineral aggregate input, until time T numerical value is equal to T0*80%, make tube mill in the operation of pre-swollen tripe state.
The time T specific method that record detector is in material is:When no material is applied pressure under detector
During end, detector does not produce displacement, and thimble does not also produce displacement, and jacking block does not contact with battery electrode column, and detection circuit is disconnection shape
State, signal processing module no signal produce;When there is material to apply pressure on the cylinder of detector lower end, detector lower end circle
Pressure is transmitted thimble by cylinder by top conical body, thimble is produced upward displacement, and jacking block contacts with battery electrode column, is detected
Circuit is "on" position, and electric signal is passed to signal processing module and changes into data signal output by detection circuit, is remembered simultaneously
It is T that record, which has the time caused by data signal, then T is the time that detector is in material.
