Description

Technical Field

[0001] This utility model relates to the field of drying tower technology, and in particular to a drying tower feeding device. Background Technology

[0002] A drying tower is a device used for drying materials. Its core function is to evaporate and remove moisture from materials using heat or other forms of energy. Drying towers are commonly used for grain drying. A grain drying tower mainly includes a drying chamber, a heat emitter, a fan, a feeding conveyor, and a dehumidification pipe. The grain is conveyed upward to the top of the drying chamber by the feeding conveyor. The grain moves from top to bottom under its own gravity and is dried by the hot air inside the chamber during this process, thus achieving the drying purpose.

[0003] The existing feeding conveyor mainly consists of multiple belt conveyors on the ground transporting grain to a vertical elevator, which then moves the grain to a position higher than the feed inlet of the drying silo. The grain is then poured into the feed inlet of the drying silo through an inclined pipe, thus achieving the feeding purpose. During the feeding process, if the feeding speed is too fast, a large amount of grain will accumulate in the drying silo, which can easily cause blockages. At this time, the feeding speed can be adjusted by stopping the feeding conveyor. However, the conveying devices of each section of the existing feeding conveyor are linked. Stopping one section will cause the entire feeding conveyor to stop, which increases the difficulty of control and increases the overall equipment burden of the feeding conveyor. Utility Model Content

[0004] This utility model proposes a feeding device for a drying tower to solve the problem that the conveying devices of each conveying section of the current feeding conveyor are all linked, and stopping one conveying section will cause the entire feeding conveyor to stop, thereby increasing the overall equipment burden of the feeding conveyor.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A feeding device for a drying tower includes an elevator with a feed inlet at its bottom and a discharge pipe at its top. An inclined pipe is connected to the bottom of the discharge pipe, and an extension of the inclined pipe is connected to a storage tank. A guide pipe is provided on one side wall of the top of the storage tank, and an outlet pipe is connected to its extension. Several perforations are opened at the bottom of the outlet pipe. A return outlet is provided on one side wall of the bottom of the storage tank, and a reflux pipe is provided on one side of the return outlet. The extension of the reflux pipe extends above the feed inlet. A liftable support plate is provided inside the storage tank, and a lifting device is provided at the bottom of the support plate.

[0007] Preferably, the elevator includes a housing, with gear shafts provided at both the top and bottom of the housing. A motor is provided outside the housing, with the output shaft of the motor fixed to the gear shaft. A conveyor chain is meshed with the gear shaft. A plurality of hoppers are provided on the outer wall of the conveyor chain. The inner cavity of the discharge pipe communicates with the housing, and a guide plate is provided on the inner wall of the discharge pipe.

[0008] Preferably, the storage tank has an inlet on one side of its top, and the inlet is connected to the extension end of the inclined tube.

[0009] Preferably, a support frame is fixed to the outer wall of the storage tank, and an mounting plate is provided on the support frame near the bottom of the storage tank. The bottom end of the lifting device is connected to the mounting plate, and the telescopic end of the lifting device extends into the interior of the storage tank and is connected to the bottom of the pallet.

[0010] Preferably, a support rod is fixed to the outer wall of the support frame, and the end of the support rod is connected to the return pipe.

[0011] Preferably, a dust suction hood is provided on one side of the feed inlet, a dust suction pipe is connected to one side of the dust suction hood, a dust collector is connected to the end of the dust suction pipe, and a fixing bracket for supporting the dust suction pipe is fixed on the top of the dust collector.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] By installing a storage tank on one side of the elevator, with a liftable pallet inside, the pallet is positioned below the end of the feed pipe inside the storage tank. After the grain enters the storage tank, it can promptly enter the feed pipe and be fed to the discharge pipe. The pallet is located at the bottom of the storage tank, allowing for the storage of a larger amount of grain. In this way, the grain can be properly managed without stopping the feeding conveyor, preventing grain from accumulating inside the drying tower. The feeding conveyor as a whole is easier to control and does not create a burden on the conveying system. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] This utility model provides, for example Figures 1-4The drying tower feeding device shown includes a hoist 1, with a feed inlet 8 at the bottom and a discharge pipe 5 at the top. An inclined pipe 6 is connected to the bottom of the discharge pipe 5. A feed inlet 23 is opened on one side of the top of a storage tank 2, connecting to the extension end of the inclined pipe 6. The extension end of the inclined pipe 6 is connected to the storage tank 2. A guide pipe 3 is provided on one side wall of the top of the storage tank 2, with an extension end connected to a discharge pipe 4. In actual use, the discharge pipe 4 is inserted into the interior of the drying tower for convenient feeding. Several perforations are opened at the bottom of the discharge pipe 4. A return outlet 24 is opened on one side wall of the bottom of the storage tank 2, with a return pipe 7 on one side of the return outlet 24. The extension end of the return pipe 7 extends above the feed inlet 8. A liftable pallet 22 is installed inside the storage tank 2, with a lifting device 12 at the bottom of the pallet 22. Grain is fed from... The feed inlet 23 enters the storage tank 2 and rests on top of the pallet 22. The pallet 22 is located on one side of the end of the guide pipe 3. After the grain accumulates on top of the pallet 22, the grain enters the guide pipe 3 from the end of the guide pipe 3 and flows to the discharge pipe 4. Finally, it is discharged from the drain hole at the bottom of the discharge pipe 4 to the drying tower. After the pallet 22 moves downward and is located above the return outlet 24, the internal space of the storage tank 2 becomes larger. After the grain enters the storage tank 2, a certain amount can be stored, which can alleviate the problem of grain accumulation inside the drying tower. After the pallet 22 moves downward to the position below the return outlet 24, the grain inside the storage tank 2 can be discharged from the return outlet 24 and flow through the return pipe 7 to the feed inlet 8, and then is lifted and conveyed again. During this process, the feeding and conveying device does not need to be stopped, the feeding and conveying is smoother, and there is no need for frequent start-stop control.

[0022] like Figure 1 and Figure 3 As shown, the elevator 1 includes a housing 21. Gear shafts 18 are provided at both the top and bottom of the housing 21. A motor 17 is provided outside the housing 21. The output shaft of the motor 17 is fixed to the gear shaft 18. A conveyor chain 19 is meshed with the gear shaft 18. Several hoppers 20 are provided on the outer wall of the conveyor chain 19. The inner cavity of the discharge pipe 5 is connected to the housing 21, and a guide plate 51 is provided on the inner wall of the discharge pipe 5. During the feeding process to the drying tower, the grain is transported to the feed inlet 8 by an external belt conveyor. After the motor 17 is started, the output shaft of the motor 17 drives the gear shaft 18, which in turn drives the conveyor chain 19. The conveyor chain 19 drives the hoppers 20 to circulate within the housing 21, thereby achieving the purpose of lifting the grain. When the hoppers 20 containing grain reach the top of the housing 21, they reverse direction and flip. The grain in the hoppers 20 falls onto the guide plate 51 and slides into the inner channel of the discharge pipe 5, and then enters the storage tank 2 through the inclined pipe 6.

[0023] like Figure 1 and Figure 2As shown, a support frame 11 is fixed to the outer wall of the storage tank 2. The support frame 11 is used to maintain the stability of the storage tank 2, so that the storage tank 2 is always in a safe state. An installation plate 10 is provided near the lower part of the support frame 11. The bottom end of the lifting device 12 is connected to the installation plate 10. The telescopic end of the lifting device 12 penetrates into the interior of the storage tank 2 and is connected to the bottom of the support plate 22. The lifting device 12 can be a cylinder or an electric push rod. When the telescopic end of the lifting device 12 extends, it pushes the support plate 22 upward.

[0024] A support rod 13 is fixed to the outer wall of the support frame 11. The end of the support rod 13 is connected to the return pipe 7. The support rod 13 stably supports the return pipe 7 to prevent shaking during the process of transporting grain through the return pipe 7, which is conducive to the accurate return of grain to the feed inlet 8.

[0025] like Figure 1 and Figure 2 As shown, a dust suction hood 15 is provided on one side of the feed inlet 8, and a dust suction pipe 14 is connected to one side of the dust suction hood 15. A dust collector 9 is connected to the end of the dust suction pipe 14. A fixing frame 16 for supporting the dust suction pipe 14 is fixed on the top of the dust collector 9. During the process of grain entering the feed inlet 8, the dust in the grain enters the dust suction hood 15 under the suction action of the dust collector 9, and enters the interior of the dust collector 9 through the dust suction pipe 14. The dust collector 9 is existing technology, and the specific dust removal principle will not be elaborated here.

[0026] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
