Abstract
The utility model discloses an air lock feeder for a vertical mill, which comprises a weighing device and a conveyor; wherein, the conveyor, which is positioned under the weighing device, is a belt weigher; which is enclosed by a closed belt weigher shell; and a belt-weigher discharge outlet which is communicated with a vertical-mill feed inlet is arranged on the belt weigher shell. Since the closed belt weigher is mounted at the vertical-mill feed inlet to control the feed speed, feed is uniform, the air lock effect is good, the circulated air flow of the system is increased, the operation of the mill can be kept reliable, the structure is simple, maitenance is convenient, and the fault rate is low.
Description
Technical field
The utility model relates to a kind of device of giving the Vertical Mill feeding.
Background technology
Vertical Mill pan feeding place lock wind is in service at Vertical Mill to be key position, and the lock feeding device major part that the Vertical Mill that most producers use is equipped with is three road gate valve controls, use, and the operating cost height, the fault rate height, maintenance is inconvenient, and the purchasing price costliness.These problems are perplexing many Vertical Mills always and are using producer, are insoluble problems.
The utility model content
Technical problem to be solved in the utility model provide a kind of simple in structure, use Vertical Mill lock feeding device reliable, easy to maintenance.
For solving the problems of the technologies described above, the technical solution of the utility model is: the Vertical Mill lock feeding device, comprise meausring apparatus, be positioned at the conveying device of described meausring apparatus below, described conveying device is a belt conveyer scale, the periphery of described belt conveyer scale is provided with airtight belt conveyer scale housing, and described belt conveyer scale housing is provided with the belt conveyer scale discharging opening that is communicated with the Vertical Mill charging aperture.
As a kind of preferred version, described meausring apparatus comprises airtight weighing tower, and the bottom of described weighing tower is equipped with LOAD CELLS, and the discharging opening of described weighing tower connects the charging aperture of described belt conveyer scale housing.
Owing to adopted technique scheme, the Vertical Mill lock feeding device, comprise meausring apparatus, be positioned at the conveying device of described meausring apparatus below, described conveying device is a belt conveyer scale, the periphery of described belt conveyer scale is provided with airtight belt conveyer scale housing, and described belt conveyer scale housing is provided with the belt conveyer scale discharging opening that is communicated with the Vertical Mill charging aperture; By the closed belt conveyer scale control blanking velocity of installing at the Vertical Mill charging aperture, blanking is even, and lock wind is effective, has increased the systemic circulation air quantity, and operation has had reliable assurance to grinding machine, and simple in structure, easy to maintenance, fault rate is low.
Description of drawings
Accompanying drawing is the structural representation of the utility model embodiment.
The specific embodiment
As shown in drawings, the Vertical Mill lock feeding device, comprise meausring apparatus, be positioned at the conveying device of described meausring apparatus below, described conveying device is a belt conveyer scale 3, the periphery of described belt conveyer scale 3 is provided with airtight belt conveyer scale housing, and described belt conveyer scale housing is provided with the belt conveyer scale discharging opening that is communicated with Vertical Mill charging aperture 4.Described meausring apparatus comprises airtight weighing tower 1, and the bottom of described weighing tower 1 is equipped with LOAD CELLS 2, and the discharging opening of described weighing tower 1 connects the charging aperture of described belt conveyer scale housing.
Belt conveyer scale is known conveying device, is a kind of equipment of belt-like transporter, and a pressure sensor is arranged below belt, and signal is passed to single-chip microcomputer, handles the back by single-chip microcomputer and shows with digital form, and instantaneous delivery and integrated flux are arranged.The motor of belt feeder is a variable-frequency motor, can change feeding speed by frequency conversion.
The operation principle of present embodiment is as follows: LOAD CELLS 2 output signals are imported the motor of belt conveyer scale 3 into by frequency converter, control the rotating speed of belt conveyer scale 3.Material for a long time, greatly then the frequency converter running frequency is low for LOAD CELLS 2 output signals, belt conveyer scale 3 rotating speeds are slow; Material after a little while, LOAD CELLS 2 output signals are little, the frequency converter frequency height, belt conveyer scale 3 rotating speeds are fast, so just realized how many problems of adapting with the blanking speed of Vertical Mill material.After present embodiment came into operation, blanking was even, and lock wind is respond well, has heightened mill output greatly, has increased the systemic circulation air quantity, and operation has had reliable assurance to grinding machine.Simultaneously, present embodiment small investment (only account for three road gate valves 1/10th), operating cost low (having only 3KW), easy to maintenance, fault rate is low, is Vertical Mill lock wind, the even auxiliary facility promoted of blanking, has solved the biggest problem of Vertical Mill lock wind.
