The utility model proposes a kind of methods for preventing the fluffy knot of material in feed bin, comprising:

Broken arch device is set in feed bin；The broken arch device is broken arch device described in one of claim 1-2；

Timing vibrating: according to preset time interval, broken arch apparatus main body is jacked up, is stopped between the preset time After two, arch apparatus main body is retracted brokenly.

The technical concept of the utility model is:

The bottom of the feed bin is located on the conveyer belt, slightly above conveyer belt, when so that conveyer belt being run, feed bin bottom Portion does not rub conveyer belt, and when conveyer belt is static, gap between the feed blocking feed bin and conveyer belt of bin bottom, material will not Outflow；Door is arranged in running direction of conveyor belt in feed bin, and material is gone out by this door；The size control opened by control door The speed of material discharging bin processed；

Conveyer belt revolving speed is adjustable, and revolving speed is faster, and blanking velocity is faster；When needing fast blanking, conveyor belt high-speed operation is needed When wanting accurate blanking, conveyer belt slow running；

The striker plate is set above the conveyer belt, when the striker plate is closed, material can only be flowed out by crossing material mouth, Most of material on conveyer belt is stopped by the striker plate；Blanking velocity is slower, is used for degree of precision blanking；It needs under high speed When material, the striker plate is opened, and material is unobstructed, quickly through.

When just starting charging, the door is opened to utmostly, and the conveyor belt high-speed rotation, the striker plate is beaten It opens；When material is added to ratio one (such as 80%), ratio two (such as 94%), be successively reduced or switched off the door, reduce it is described defeated It send with revolving speed (being reduced or switched off the door, the sequence of the reduction conveyer belt revolving speed can be used interchangeably)；Material is further When being added to ratio three (such as 97%), the striker plate is closed；When material is further added to setting weight (such as 99.8%), stop institute State the rotation (material that conveyer belt stopping reaction process being taken out of, so that the finally obtained material essence of the weigh hopper of conveyer belt Really close to setting weight).

When accurate charging, the striker plate above the conveyer belt falls, and can intercept big on the conveyer belt The discharging of partial width, only small part, which discharge, to be moved ahead under the drive of the conveyer belt by the material mouth excessively, continuation, The weigh hopper is fallen to, thus accurate measurement.

When charging starts next time, the door is opened, and the striker plate on the conveyer belt fully opens, described Conveyer belt quick rotation, the material that the striker plate intercepts accumulation when last accurate charging are quickly delivered to the weighing and expect Bucket.Sequence cycle operation according to this.

The technical concept of broken arch device is: the material in feed bin, in timing, on the whole under it is loose in the case where, fluffy knot is existing As that can mitigate significantly, it is conducive to blanking.

The present apparatus is suitable for, and metallurgy, chemical industry, the industries such as food need rapid loading precision metering equipment, production line, improves Its production performance.It, can be faster using the equipment of the stop gauge or quick high accuracy proportioner or broken arch device, production line Fast, more accurate ingredient, production.

Beneficial effect

Quick high accuracy proportioner described in the utility model, the unlatching size of the discharge port by adjusting feed bin, comes The discharging speed of feed bin is controlled, ingredient speed, precision are controlled.

By controlling the speed of service of conveyer belt, to control the rate of conveyer belt outputting material, ingredient speed, essence are controlled Degree.

Pass through, when ingredient initial stage, the discharge port of feed bin significantly opened, conveyor belt high-speed operation, controls high speed blanking, real Now high speed ingredient.

When ingredient reaches the middle and later periods of this ingredient, the discharge port by controlling feed bin opens amplitude and becomes smaller, and controls defeated Send band slow running, close the measures such as striker plate, to reduce the rate of conveyer belt outputting material, realize material at a slow speed, miniflow The accurate measurement control in ingredient latter stage is realized in amount conveying.

Quick high accuracy proportioner described in the utility model, by the high speed blanking of ingredient early period, mid-term, the later period by Blanking velocity is gradually reduced, latter stage blanking at a slow speed realizes high speed (time is short), the high-precision of ingredient overall process.

Quick high accuracy proportioner described in the utility model is kept away by the way that a discharge port is only arranged in a feed bin When having exempted from a feed bin has two discharge ports, the fluffy material phenomenon that is easy to appear between two discharge ports.

Quick high accuracy proportioner described in the utility model uses a set of quick high accuracy proportioner, Neng Goushi Existing rapid loading, middling speed charging, slow-addition, accurate charging；Charging precision is high, speed it is fast (at 10 kilograms of charging, charging precision It can reach within 0.1% error, used time 5-7 second)；It is suitable for solid-granular material, powder, cementability mixture；It repeats to control Accuracy error processed is small；Not fluffy material.Charging rate and control precision are superior to the quick high-precision of existing double helix and Dual-conveying tall band Spend proportioner.

Broken arch device described in the utility model can effectively realize brokenly arch, prevent fluffy material, and structure is simple, cost Cheap, failure rate is low.

Quick high accuracy proportioner described in the utility model, failure rate is low, and manufacturing cost is low, easy to operate.

The present apparatus is suitable for, and metallurgy, chemical industry, the industries such as food need rapid loading precision metering equipment, production line, improves Its production performance.

The utility model proposes a kind of quick high accuracy distributions, can control quick high accuracy proportioner and carry out fastly The high-precision dispensing operation of speed.

The utility model proposes a kind of method for preventing the fluffy knot of material in feed bin, the object in loose silo that can be automated Material, prevents the fluffy knot of the material in feed bin.
