Abstract

The invention discloses a screw feeder. The screw feeder comprises a support, a feeding pipeline, a feeding hopper and a discharging port. The feeding hopper and the feeding pipeline are connected through a discharging pipe. The section, close to the feeding pipeline, of the discharging pipe is an arc pipe. A screw shaft is arranged in the feeding pipeline. One end of the screw shaft is connected with a motor, and the other end of the screw shaft is connected with a water inlet hopper. The discharging port is connected with a material distributing port through a rotating shaft. The side wall of the material distributing port is connected with a piston of an air cylinder. The screw feeder is simple in structure, high in conveying capability, capable of finishing conveying of materials of various particle sizes, and wide in application range. The materials can be prevented from being excessively abraded in the conveying process through the arc pipe, and the service life of the screw feeder is prolonged; and the blockage is not likely to happen during conveying.

Description

A kind of feeding screw
Technical field
The present invention relates to a kind of feeding screw.
Background technology
Conveying worm is from the angular divisions of conveying material direction of displacement, and conveying worm is divided into Horizontal-type screw conveyer Type big with vertical screw conveyor two.Wanting of the spirochetal rotating ratio normal spiral conveyer of vertical screw type conveyer Height, the material of addition under the influence of centrifugal force, and creates frictional force between casing, this frictional force stops material with helical blade Rotate and overcome the gravity that material declines together, it is achieved thereby that the vertical transport of material.This machine conveying capacity is little, delivery head Little, rotating speed is higher, and energy consumption is big.The powder and granule shape material that particularly suitable flow behavior is good, is mainly used in improving material, hoisting depth It is generally no greater than 8 meters.When material adds in fixing trough, due to material gravity and and trough between friction masterpiece With, the material being deposited in trough bottom does not rotates with spirillum, and only moves forward under the helical blade rotated promotes, as It is the same that non-rotary nut makees translational motion along the screw rod rotated, and reaches to carry the purpose of material.This machine is easy to multiple spot charging With discharging, course of conveying can complete mixing, stirring or refrigerating function simultaneously.To overload sensitivity, easily block;Material is had broken Loss, the simple in construction of horizontal screw conveyer, it is simple to install and keep in repair and troubleshooting.
Existing conveying worm in course of conveying, due to charging aperture great majority connect loading hopper, loading hopper with Without associated buffer structure between charging aperture, to the helical blade within conveying worm and helical axis bring powerful impulsive force or Person's pressure, easily causes the abrasion of material or helical blade or helical axis;Helicla flute (machine due to helical blade Yu conveying worm Body shell) between gap be fixing, this gap width is too small, and material then can not smooth and easy pass through, then between material may be stuck in In gap, owing to the dissection of storeroom friction, extruding and helical blade is by causing the rising of the percentage of damage of material, it is unfavorable for Subsequent reactions process or the control of progress;If gap width is excessive, then the material in gap under the effect of internal friction by axle To movement;So, in order to make, material energy granulate is smooth and easy to be passed through, and when design, helical blade cannot be less than with spiral fluted gap width The full-size of material.But, in actual use, owing to the gap between helical blade and the helicla flute of conveying worm is Fix, and conveying worm it is frequently necessary to transport the material that some hardness are relatively big and particle diameter process is uneven, such as material particular diameter Approximate or time slightly below wherein partial material particle diameter is only slight beyond above-mentioned gap width, under gravity so that Gather substantial amounts of material bottom spiral fluted, add the pressure that a large amount of materials within loading hopper produce, the most then make spiral The resistance that blade produces when rotated increases so that the load of motor increases, and equipment energy consumption improves;Heavy then make helical blade Easily by material card master, getting lodged in inside helicla flute, cause equipment to be worn, service life of equipment reduces;And some materials are the easiest Caused material to be worn by the frictional force of helical blade with helicla flute or the interaction of storeroom, crush.
Sodium sulfide production process can produce a lot of waste material, containing a large amount of sulfide in waste material, by screw feeding track Delivering to waste tank process, existing technique is first waste material to be sent into treatment trough, delivers to give up through feeding screw again after the stirring that adds water Material pond;In feeding screw works, waste material is easily dried and condenses, thus results in blockage,.
Summary of the invention
It is an object of the invention to provide a kind of feeding screw, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: a kind of feeding screw, including support, feed pipe Road, loading hopper and discharging opening, be connected by tremie pipe between described loading hopper and charging line, the nearly feed pipe of tremie pipe One section of road is curved pipe;Being provided with helical axis in charging line, one end of helical axis is connected with motor, and the other end is with water inlet bucket even Connect;Described discharging opening is connected with cloth mouth by rotating shaft, and cloth mouth sidewall is connected with the piston of cylinder.
Preferably, described charging line is connected air vent, is provided with exhaust fan in air vent.
Preferably, the axis of described helical axis and bucket UNICOM of intaking, helical axis is provided with apopore.
Compared with prior art, the invention has the beneficial effects as follows: present configuration is simple, conveying capacity is strong, can complete many Planting the conveying of particle diameter material, purposes scope is wide;Utilize curved pipe that material can be avoided by too much abrasion when conveying, improve equipment Service life;When conveying, being not susceptible to blocking, implementation result is good.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Fig. 2 is to send out big figure in Fig. 1 at 4.
In figure: 1 loading hopper, 2 tremie pipes, 3 charging lines, 4 helical axis, 5 motors, 6 water inlet buckets, 7 cloth mouths, 8 aerofluxuss Mouthful, 9 cylinders, 10 rotating shafts, 11 discharging openings, 12 supports, 21 curved pipes, 81 exhaust fan, 41 apopores.
