Description

Technical Field

[0001] The invention relates to the technical field of flour processing equipment, in particular to a drying device for flour processing. Background Art

[0002] Flour is an important staple food in people's lives. During its processing and production, bagged flour needs to be stored in a dry and ventilated environment. However, due to long-term storage and changes in the storage environment, the flour at the bottom often becomes damp. At present, for damp flour, workers often use sieves to separate it first, remove larger lumps, and manually remove the coagulated and moldy parts, and then crush and dry the small pieces of flour again for recycling. However, the process is relatively complicated and relies on manual operation, which greatly reduces the screening efficiency and is not conducive to the processing operations of enterprises. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a drying device for flour processing in response to the above-mentioned technical deficiencies. Relying on airflow and separation adsorption parts, the device can quickly complete flour screening and recovery without manual operation in the middle, greatly improving the screening efficiency, simplifying the construction process, and being able to meet large-scale processing needs and promote the normal development of the enterprise.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention includes:

[0005] A chassis is provided with a guide channel on the top of the chassis, two jet sources are symmetrically arranged below the guide channel, a feeding assembly is arranged in the middle of the guide channel, a flippable tray is arranged below, and a separation adsorption component is arranged at the discharge end of the tray.

[0009] Preferably, a second hydraulic cylinder connected to the chassis is provided under the tray, the interior of the tray is a hollow structure, the surface is made of a flexible material, and the interior is filled with a medium.

[0010] Preferably, the separation adsorption component includes a bottom plate, an upper box body and a pressure plate; the bottom plate is tilted and fixed on the chassis and is located below the discharge end on the right side of the tray, and a plurality of air injection holes are evenly arranged on the bottom plate; the upper box body is slidably connected to the chassis and is arranged parallel to the bottom plate, and a third hydraulic cylinder is provided above the upper box body; the upper surface of the pressure plate is connected to the third hydraulic cylinder and forms an exhaust cavity with the upper box body, and the exhaust cavity is connected to the powder outlet of the guide channel, and a plurality of suction holes and a flexible tentacle structure are evenly arranged on the pressure plate.

[0011] Preferably, the bottom plate is provided with evenly distributed tentacle structures.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] 1. The upward thrust is generated by the airflow, which can separate the flour and the powder blocks at one time. After falling, the powder blocks are rubbed by the separation adsorption parts to crush the small powder blocks and remove the harder powder blocks, thus avoiding the pollution of the original flour by the unusable part. The structure is reasonable and reliable.

[0017] 2. The overall screening efficiency is greatly improved through the cooperation between the jet source and the separation adsorption component, and the feeding component is used for automatic feeding, without manual participation in the middle, which reduces the labor intensity and is easy to promote in the factory area;

[0018] 3. During the kneading process, the separation adsorption part generates negative pressure adsorption capacity, and cooperates with the air blowing on the bottom plate to recycle the crushed flour again, and connects with the guide channel to achieve centralized storage and utilization, with a reasonable layout;

[0019] 4. The feeding component slowly pushes the incoming flour out of the storage box by pulling, and cooperates with the jet source to effectively separate the powder and the lumps. Compared with the traditional vibration screening, it avoids the damage of moldy powder lumps and affects the overall recovery quality;

[0020] 5. The tray surface forms a flexible support, which can greatly reduce the damage of the powder blocks when they fall, so that the kneading operation can be carried out again as needed, which is safe and reliable;

[0021] 6. The circulating drying component dries the recovered flour and automatically completes the collection and utilization, saving labor. It can better match the screening structure part to form a complete processing production line. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] A preferred embodiment, combined with Figure 4 and Figure 5 As shown, the feeding assembly 3 includes a material storage box 301 and a first hydraulic cylinder 302; the material storage box 301 is fixed in the middle area of ​​the guide channel 101, and a feeding pipe 303 connected to the outside is provided on one side; the first hydraulic cylinder 302 is fixed on the top of the chassis 1, and a lifting member 304 is provided on the push rod of the first hydraulic cylinder 302, and the lifting member 304 is in the shape of a rectangular strip and has a certain height; when feeding, the first hydraulic cylinder 302 pushes the upper surface of the lifting member 304 close to the lower surface of the material storage box 301, thereby reserving a volume space for flour to slide out of the feeding pipe 303, and when feeding is needed, the first hydraulic cylinder 302 pulls upward to drive the internal flour to fall from the top of the material storage box 301, thereby realizing feeding.

[0038] A preferred embodiment, combined with Figure 4 As shown, the bottom of the lifting member 304 has an arc-shaped surface, which reduces the interference with the airflow below when the guide channel 101 is cleared.

[0039] A preferred embodiment, combined with Figure 1 and Figure 5 As shown, a second hydraulic cylinder 401 connected to the chassis 1 is provided under the tray 4 for controlling the tilt angle of the tray 4. Meanwhile, the right side of the tray 4 is connected to the chassis 1 by a rotating shaft. The interior of the tray 4 is a hollow structure filled with gas or liquid.

The exhaust cavity 801 is connected to the powder outlet of the guide channel 101 through a pipeline. A plurality of suction holes 802 and a flexible tentacle structure 803 are evenly arranged on the pressing plate 8. After the flour reaches the bottom plate 6, the third hydraulic cylinder 701 pushes the pressing plate 8 to move so that the tentacle structure 803 contacts the flour block. During the downward pressing process, the flour block that is not seriously affected by moisture can be punctured and broken, while the moldy part will not be damaged.
