Detailed description of the invention
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is as the effect of the mutual alignment between the shape of related each member, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present invention, technical scheme.
Known referring to Fig. 1, airslide disintegrating mill mainly comprises source of the gas 1, gas source pipe 2, pulverizing pipeline 3, feed line 4, unidirectional feeding port 5, former pocket fixed mount 6, feed back pipeline 7, disintegrating area 8, pressure gauge 9, former pocket 10 and separates hoop 11.
Known referring to Fig. 2, former pocket 10 is the canvas bag of a tubular, and for taking up the raw material of tentatively having pulverized, former pocket 10 vertically hangs in former pocket fixed mount 6, top is connected with feed back pipeline 7, for detachable, need to add raw material from this, former pocket 10 bottoms are provided with a unidirectional feeding port 5, it is connected with feed line 4, outwards transferring raw material, unidirectional feeding port 5 ensures outwards transferring raw material of this place, not inwardly air blast.Because unidirectional feeding port 5 calibers are less, in the time of transferring raw material, may cause hole to stop up, therefore need to the ceaselessly disturbance in bottom, above former pocket 10 and feed line 4 connectivity ports, be provided with a stirring port 12, and by the stirring port 12 tubular sealing that caved inward stir cover, hand is put in stirring by staff like this, or insert a transit mixer, unimpeded to ensure feeding.Above-mentioned transit mixer is according to this product design, the stirring rod that comprises motor, is connected with machine shaft, stirring rod is installed on the position of departing from machine shaft axis, and under oblique, insert in stirring port 12, according to the size of former pocket 10, it is 10-30 degree that stirring rod departs from machine shaft axis angle.
When raw material conducting powder is broken, conventionally need to repeatedly pulverize, need on the body between former pocket 10 and feed back pipeline 7 and feed line 4 connectivity ports, install one and there is the separation hoop 11 that tightens up former pocket 10 functions, normally in the centre position of former pocket 10, separate after hoop 11 fixing like this, former pocket 10 directly can be separated into two regions, the first half is collected the raw material of pulverizing once, and the latter half is the raw material that need to pulverize.For improving equipment automatization function, separating hoop 11 can be the rope of a rhizosphere around former pocket 10 1 weeks and intersection, this rope one end is fixed, the other end is wound in to be separated on hoop machine shaft, one number of turns becket can be installed on former pocket 10, thereby coordinate rope to fix, rope can tighten up or loosen former pocket 10 with electric machine rotation like this.For whether convenient former pocket 10 bottoms of automatically measuring also have the raw material of not pulverizing, and former pocket fixed mount 6 between be provided with one metering former pocket weight pressure sensor, becket on former pocket 10 can be hung on former pocket fixed mount 6, can avoid so the former pocket 10 of the first half to impact in weight the former pocket 10 of the latter half simultaneously.
Former pocket 10 is communicated with disintegrating area 8 by feed back pipeline 7, it is liner that disintegrating area 8 adopts white corundum, exceed standard so prevent heavy metal from coming off, oppositely extend and pulverize pipeline 3 along the same axis in disintegrating area 8, two pulverizing pipelines 3 are all communicated with source of the gas 1 by gas source pipe 2, two pulverizing pipelines 3 are provided with and are equipped with pressure gauge 9, and whether pipeline 3 is pulverized in monitoring constantly has extremely, avoid accident to occur.Two pulverizing pipelines 3 can be communicated with same source of the gas 1 by three-way pipe, also can be communicated with two sources of the gas 1 respectively.Feed line 4 is connected on two pulverizing pipelines 3 by two arms, like this source of the gas 1 produce air pressure through gas source pipe 2 to pulverize pipeline 3 input, pulverizing pipeline 3 and feed line 4 interfaces generation negative pressure, raw material in former pocket 10 is sucked and pulverizes pipeline 3, and accelerate in inside, and in opposite directions in the positive head-on collision in disintegrating area 8, reaching pulverizing object, the raw material after collision crashing returns to former pocket 10 through feed back pipeline 7 and collects.
This equipment output gas flow adopts homogeneous flow field model in Dual-Phrase Distribution of Gas olid to carry out designing and calculating, in flow Field Design, apply the oblique shock wave boundary-layer backflow duty of LAVAL jet pipe, adopting white corundum is liner, and by specific functions such as inwall feed back, lax jets, what increase powder granule hits probability and equipment grindability certainly.In design, having introduced the pulvis new ideas of fluidized suspension, is that the granularity of material is more carefully more even, can be applicable to the ultra-fine grinding of various dry powders, and fineness scope can be between 43 ~ 1 μ m.Whole crushing process carries out in totally-enclosed environment, can require to adopt according to the difference of comminuting matter to purify air, purify the different gas phases such as inert gas.
In order to improve the automation performance of equipment, can join controller for airslide disintegrating mill, this controller is provided with input, demonstration and alarm equipment, and its output start stop command is to source of the gas 1, transit mixer and separation hoop motor, and accepts pressure gauge 9 and check signal and measuring-signal.Input equipment can be inputted control commands such as pulverizing requirement, and display device can show pressure gauge, pressure sensor monitoring data, and pulverizes the data such as number of times.
Utilize this automation equipment, airslide disintegrating mill control method:
System powers on;
Wait set pulverize number of times, can manually on input equipment, input, with pulverize raw material require self-defined, when set after, equipment according to set pulverizing number of times start working;
Tighten up and separate hoop 11 rear startup source of the gas 1 and transit mixers;
Receive in real time pressure sensor and pressure gauge 9 signals, and data are done following two step decision operation constantly:
Judge 1, A is for the situation of only having a source of the gas 1: compare with safe threshold values respectively with value and difference if two pressure gauges 9 are that measure, shut down alarm if exceed safe threshold values scope, if work within the scope of safe threshold values; B is for the situation that has two sources of the gas 1: the force value that two pressure gauges 9 are measured and safe threshold values are compared, if improve and corresponding source of the gas 1 power of this pressure gauge 9 higher than safe threshold values, if reduce and corresponding source of the gas 1 power of this pressure gauge 9 lower than safe threshold values;
If judge, 2 pressure sensor picked up signal bind round 11 belows without raw material for separating, and close source of the gas 1 and transit mixer, open afterwards after 11 Preset Times are bound round in separation and again draw in, and then start source of the gas 1 and transit mixer, and count pulverizing once;
Be circulated to successively to set and pulverize number of times, close source of the gas 1 and transit mixer.
By reference to the accompanying drawings the present invention is exemplarily described above; obviously specific implementation of the present invention is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present invention design and technical scheme carry out; or without improving, design of the present invention and technical scheme are directly applied to other occasion, all within protection scope of the present invention.
