Technical solution to further illustrate the present invention below with reference to the accompanying drawings and specific embodiments.
For make present invention solves the technical problem that, the technical solution that uses and the technique effect that reaches it is clearer, below
The technical solution of the embodiment of the present invention will be described in further detail in conjunction with attached drawing, it is clear that described embodiment is only
It is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those skilled in the art exist
The every other embodiment obtained under the premise of creative work is not made, shall fall within the protection scope of the present invention.
As shown in Figure 1, screw conveyor provided by the invention includes：Driving device, chute feeder 7, feed pipe 9 and feeding spiral shell
Rotation 8, chute feeder 7 and 9 equal gap of feed pipe are set in 8 outside of feeding screw, and 7 rear end of chute feeder is provided with feed inlet, feed pipe 9
It is connected to 7 front of chute feeder, the front end of feed pipe 9 is provided with discharge port；Feeding screw 8 is connect with the output end of driving device,
The screw pitch that feeding screw 8 is located at the part in chute feeder 7 is less than the screw pitch being located in feed pipe 9.The conveying capacity of fine pitch is less than
The conveying capacity of big screw pitch, i.e. material conveying capacity in chute feeder 7 are less than the material conveying capacity in feed pipe 9, can make feeding in this way
Material in pipe 9 is comparatively fast sent out, and is reduced material particles and is excessively compressed and rubbed against and be crushed in feed pipe 9, that is, mitigates
The phenomenon that solid accumulation blocks in feed pipe 9.
Further, feeding screw 8 is arranged diagonally downward from feed end to discharge end, axis and the feeding spiral shell of feed pipe 9
The axis of rotation 8 is arranged in parallel.Screw conveyor further includes feeding equipment, the outlet connection of feed inlet and feeding equipment, feed inlet
It is arranged in the upside of chute feeder 7.Wherein, feeding equipment is hopper 11, and the upper end use of hopper 11 opens flanged joint soon head cover
12.Specifically, it is a circular lid mouth for being evenly equipped with 6 screw holes to open flange soon, is provided on opposite head cover 12 and circular lid
The corresponding through-hole of screw hole on mouth, adjusting screw pass through the through-hole on head cover 12 to be screwed into the screw hole on lid mouth and realize lid
It closes, when needing to open, can easily unscrew adjusting screw and open head cover 12.Further, 7 outside of chute feeder is provided with
Bobbing machine 6.Further, the discharge port of feed pipe 9 is connected with downwards tremie pipe 10.Further, tremie pipe 10 passes through hose
15 connect with storage equipment 16.Feeding screw 8 and feed pipe 9, which are obliquely installed, to be conducive to material and is sent, in addition bobbing machine 6 shakes
Action is used, and material is more open in feed pipe 9, these special design methods greatly reduce material quilt in feed pipe 9
It excessively compresses and rubs against and is crushed, is i.e. accumulated plugging phenomenon, be located at the effect of vibration of the bobbing machine 6 in 7 outside of chute feeder
It can avoid bridging phenomenon of the material between feeding equipment and chute feeder 7.
Specifically, chute feeder 7 is cuboid slot, and the upper end is opening, is connect with the outlet of 11 lower end of hopper.Feeding screw
One section of lateral gap between 8 rear end and chute feeder 7 is arranged with shell 17, and front end and the chute feeder 7 of the shell 17 weld,
Rear end is connect with the axis of feeding screw 8 by sealing bearing.The front end of chute feeder 7 is connected to feed pipe 9 to be welded together, feeding
2-5 times of the diameter of the axis of a diameter of feeding screw 8 of pipe 9, such diameter difference can ensure that material is smoothly exported, and squeeze
Pressure abrasion is smaller.
Further, driving device includes drive motor 1, reduction box 2 and shaft coupling 3, the input shaft of reduction box 2 and driving
Motor 1 connects, and the output shaft of reduction box 2 is connect by shaft coupling 3 with feeding screw 8.Further, screw conveyor further includes
Control device, control device include frequency converter 13, velocity sensor 5 and controller 14, and frequency converter 13 is connect with driving device, speed
Degree sensor 5 is arranged in feeding screw 8 close to one end of driving device, frequency converter 13 and velocity sensor 5 with controller 14
Connection.Wherein, one end of the close driving device of feeding screw 8 is arranged with turntable 4, and velocity sensor 5 is arranged on turntable 4.
Reduction box 2 can control the maximum (top) speed of feeding screw 8, therefore controllable maximum charging rate, while drive motor 1 uses frequency conversion
Device 13 controls, and can make the arbitrary speed governing within the scope of maximum (top) speed of feeding screw 8, and the feeder of 11 top of hopper can appoint as a result,
Speed of anticipating work.The actual speed of feeding screw 8 is detected by the velocity sensor 5 on turntable 4 and by speed feedback signal
To controller 14.When feeding screw 8 is stuck, the signal of velocity sensor 5 becomes 0, and driving is immediately controlled in controller 14
Motor 1 is stopped, and so can avoid feeding screw 8 and is forced the case where torsion to damage even twists off.Tremie pipe 10 passes through
Hose 15 is connect with storage equipment 16, can be transmitted to storage equipment to avoid the vibration of feeder, screw conveyor and bobbing machine 6
On 16.Using flanged joint is opened soon between head cover 12 and hopper 11, facilitate feeding operation.Screw conveyor provided by the invention was both
It can be used for dryness system, the system that also can be used for having certain humidity.
Screw conveyor provided by the invention, before being with material direction of advance, feeding section rear is provided with chute feeder 7, preceding
Side is provided with feed pipe 9, and material enters from the feed inlet of chute feeder 7, is covered on feeding screw 8, when feeding screw 8 rotates
When, material is pushed forward by feeding screw 8 to be sent out by feed pipe 9 from discharge port.Spiral shell of the feeding screw 8 in chute feeder 7
Away from less than the screw pitch in feed pipe 9, the conveying capacity of fine pitch is less than the conveying capacity of big screw pitch, i.e., the material conveying in chute feeder 7
Amount is less than the material conveying capacity in feed pipe 9, the material in feed pipe 9 can be made comparatively fast to send out in this way, reduce material particles and exist
It excessively compresses and rubs against and is crushed in feed pipe 9, that is, alleviate the phenomenon that solid accumulation blocks in feed pipe 9.Feeding spiral shell
Rotation 8 and feed pipe 9, which are obliquely installed, to be conducive to material and is sent, in addition the effect of vibration of bobbing machine 6, material is in 9 internal ratio of feed pipe
Loosely, these special design methods greatly reduce material and are excessively compressed and rubbed against and be crushed in feed pipe 9,
That is accumulated plugging phenomenon, the effect of vibration for being located at the bobbing machine 6 in 7 outside of chute feeder also can avoid material in feeding equipment and feeding
Bridging phenomenon between slot 7.
