Description
Technical field
The invention belongs to coal powder metering transportation art, it is related to coal dust conveying, the metering of the industry such as cement plant, limekiln,
More particularly to a kind of Optimal improvements for being exclusively used in coal powder metering induction system.
Background technology
Coal powder metering induction system is mainly used in the conveying, metering and lock wind of coal dust in the industrial factory such as cement plant, limekiln
Problem, accurate continuous data is provided for produced on-site control, management.Coal powder metering induction system is main by Pulverized Coal Bin, coal dust
Meter, injector, transfer pipeline composition.Coal dust is entered by Pulverized Coal Bin, then is sent into by coal powder metering device in injector, passes through spray
Coal dust is sent into transfer pipeline by emitter.According to the rotating speed of gas product flow readjustment coal powder metering device in actual production, so as to realize bio-occlusion
Material.Wherein coal powder metering device is the core of whole system, is related to the accuracy and continuity of coal dust conveying.Original coal
Powder meter uses the structure of helical feed, and this structure has no problem on service precision.But what helical feed was used
It is screw rod structure, length is 1385mm, and single device floor space is big.Meanwhile, elongated screw rod is in machining accuracy and peace
Dress precision is all difficult to ensure.Equipment gross weight is 154Kg, overhauls relatively difficult in limited space.
The content of the invention
The present invention is mainly difficult to ensure that there is provided a kind of new coal to solve above-mentioned coal dust precision in course of conveying
Powder metering conveyor, reduces equipment volume in fact, and speed is efficiently adjustable, greatly reduces fault rate, and tooth can be changed at any time
Wheel, has simplified device structure, it is ensured that overall transportation performance.
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
There is provided a kind of new coal powder metering conveying equipment, it includes feeding storehouse 3 and motor 1, described driving
It is connected with motor and feeding mouth 5 and discharging opening 7 with facing, described driving is provided with drive shaft 6, described feeding storehouse
Axle is inserted into feeding storehouse, is fitted with feeding gear on the driving shaft, the inner chamber shape of the profile of feeding gear just with feeding storehouse
Shape matches, and double helical tooth is carried on the outer wall of feeding gear 4.
Further, feed hopper is connected at the feeding mouth 5 of feeding storehouse.
Further, two bearings are fitted with described drive shaft, drive shaft is erected at feeding storehouse by two bearings
In.
Further, one is provided with feeding storehouse 3 on the inside of each bearing and lets out powder through hole through feeding storehouse.
Further, in addition to reductor 2, described motor is connected with reductor, described drive shaft and deceleration
The output end of machine is connected.
Further, described reductor is cycloidal planetary gear speed reducer.
Further, two bearings are fitted with described drive shaft, each bearing, which is fitted in, is preset in 3 liang of feeding storehouse
On the bearing block at end.
Therefore, the present invention has advantages below：
The problems such as solving big floor space, maintenance difficult, using new structure, the machine conveyed using herringbone gear
Structure.In the case where conveying capacity is constant, using new gear conveying mechanism compared to above-mentioned helical feed, overall length contracting
715mm is kept to, floor space is reduced 49%, feed precision is more accurate.Using herringbone bear structure, equipment gross weight is
75Kg, reduces 52%, is easy in limited space mounting and equipment replacement.Using herringbone bear structure, axle shortens, processing essence
Degree and installation accuracy are more easy to guarantee, and overhaul of the equipments is easier.The mitigation of weight of equipment reduces the cost of equipment.Space structure
Miniaturization, the more lightweight for doing equipment platform reduces the cost of platform.
Conventional screw conveyor is required for being fitted in batch bin, its nacelle narrow space, and overhaul of the equipments is complicated, especially
It is that leading screw can not ensure the precision that residence is needed in process, error, and spiral easily occur because screw rod is longer
Mode of movement conveys for friction-type, and freight volume and the speed of mainshaft are not directly proportional, and transports precision controlling relative difficulty, influences dispensing
Energy.
The herringbone toothing of use so that in use, material can be trapped in V-arrangement teeth groove equipment, passes through height
Axial symmetry design placed in the middle, it is ensured that feeding gear property placed in the middle and then the precision for ensureing feeding gear, takes in feeding gear
With completely enclosed vacuum cavity is realized in the presence of feeding chamber, rely on to extract and send out material with material toggling effect.This equipment is
Constant volume type conveying equipment, it is to avoid the uncertainty in friction-type course of conveying, improves running precision, simplifies electrical equipment
Control mode, and save debug time.
