Description
Technical field
The utility model patent relates to a kind of sieve damaged detection technique, particularly a kind of automatic detection device of pulverizer sieve sheet of pulverizer.
Background technology
Pulverizer is one of most important equipment in Feed Manufacturing process, and the uniformity of the fineness of materials that it pulverizes out has directly determined quality and the culture efficiency of feed.Cereals raw grain accounts for the overwhelming majority at animal and fowl fodder formula, and ratio generally meets or exceeds 60%, and animal and fowl fodder is exactly the pulverizing of cereals raw grain by the main working tasks of pulverizer, and the quality of its pulverizing has determined feed quality simultaneously.The cereals raw grain of pulverizing by pulverizer at present, cause second-rate because the condition such as storing up, conventionally contain some stones, iron is assorted etc., the cleaning product of front-end process configuration can not complete 100% clean out stone and iron is assorted, cause participating in pulverizing together with cereals raw grain in its pulverizing chamber that enters into work by pulverizing drawing-in device, pulverizing under the strike of hammer leaf, stone and iron is assorted generally can be broken up pulverizer sieve sheet and fly out, cereals raw grain is after the strike of hammer leaf, not reaching the fineness needing will fly out from sieve breakage, become bulky grain.Oarse-grained modified weak effect under the equal modified time, after granulating, quality and outward appearance are all poor, affect perception and the culture efficiency of feed.The damaged following problem that generally all exists that detects of existing pulverizer sieve sheet:
1, current feed engineering does not generally have the sieve damage detection device of pulverizer, feed factory general with manually at set intervals deallocation feed bin top sample and see whether in material, whether have bulky grain to differentiate pulverizer sieve sheet has breakage, see while having bulky grain, in batch bin, material pollutes, cannot judge pollutant number, cause whole storehouse material normally to use.
2, use the breakage of manually observing pulverizer sieve sheet in the sampling of batch bin top, because of the time interval long, generally meet or exceed half an hour, thereby can not accomplish that system responds fast, the while can not meet the requirement of Feed Manufacturing engineering automation control.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, a kind of automatic detection device of pulverizer sieve sheet is provided, automatically whether damagedly detect pulverizer sieve sheet, response time is shorter, avoid large granular materials to enter batch bin, the disadvantage that elimination artificial judgment is brought also can meet the automation control requirement of Feed Manufacturing factory simultaneously.
For achieving the above object, the technical scheme that the automatic detection device of the utility model pulverizer sieve sheet adopts is:
A kind of automatic detection device of pulverizer sieve sheet, comprise screening plant, for screening materials carrying, screening plant is arranged on the discharging opening of pulverizer, described screening plant comprises screen cloth, the pore size of this screen cloth is suitable with the aperture of pulverizer sieve sheet, above screen cloth, remain with large granular materials, this screen cloth and horizontal plane have certain angle, minimum point at screen cloth is provided with discharge gate, be provided with the long-pending assorted cylinder of accepting material at discharge gate place, large granular materials on screen cloth enters long-pending assorted cylinder under vibration and Action of Gravity Field, bottom at long-pending assorted cylinder is provided with sensor, sensor is for detection of whether having material in long-pending assorted bucket.Material after pulverizing enters screening plant, under the filtration of screen cloth, material after pulverizing enters below screen cloth, do not have pulverized large granular materials to stay screen cloth upside, under the effect of vibration of gravity and screen cloth, flow to discharge gate and enter long-pending assorted cylinder, sensor detects the material alarm in long-pending assorted cylinder, has the sieve of large granular materials explanation pulverizer to have damage to need to repair in time.Also sensor can be connected with the control circuit of pulverizer, realize and automatically control pulverizer, be the automated production basis that facilitates.
Also comprise take out device, described take out device enters screening plant from the drawing mechanism feeding of pulverizer by mass transport.
Below described screen cloth, being provided with material channel is connected with the drawing mechanism of pulverizer.Material after the pulverizing of sieving out drains to below screen cloth and collects into drawing mechanism along material channel.
This sensor is connected with the control circuit of pulverizer.
The cylinder end of described long-pending assorted cylinder, is provided with open-and-close mechanism, can open and close.Open-and-close mechanism is convenient to remove the large granular materials in long-pending assorted cylinder, for detect and provide convenience next time.
Described sensor is photo-electric or blocking rotary type sensor.Sensor is photo-electric or blocking rotary type sensor, also can adopt vibrating sensor to be arranged on long-pending assorted cylinder bottom, detects the impact shock of large granular materials to bottom.
The utility model compared with prior art, has the following advantages:
Response time is short, the damaged device of automatic detection grinding screen plate is set at pulverizer discharging opening place, in the time that sensor detects while there is bulky grain in comminuting matter sample automatic alarm, bypass is beaten in the threeway that this Plant arrangement can be entered to batch bin at elevator, the material that has bulky grain not pulverize is got to other batch bins automatically, do not affect the use of material in former batch bin; At pulverizer discharging materials sealing spiral conveyer discharging opening, place arranges this device, its automatic sampling, and interval time is adjustable continuously, sampling interval is little, greatly promote the reaction time of system, the alarm signal that the utility model sends simultaneously can be transferred to Feed Manufacturing engineering electric-control system, is convenient to the automation control of engineering.
Brief description of the drawings
Fig. 1 is the structural representation of the automatic detection device of pulverizer sieve sheet.
Wherein, 1 crusher discharger, 2 take out devices, 3 screening plants, 4 long-pending assorted cylinders, at the bottom of 5,31 screen clothes, 32 material channels, 33 discharge gates, 6 sensors.
