Description

Anti-agglomeration mechanism of a screw powder feeder

Technical Field

The utility model belongs to the technical field of powder material conveying equipment, in particular to an anti-agglomeration mechanism of a screw powder conveyor.

Background Art

1. Raw material preparation: prepare the main raw materials for spicy strips, including flour, starch, etc.

2. Dough preparation: Mix flour and starch in a certain proportion, add appropriate amount of water and stir into dough. The dough needs to go through the process of stirring and fermentation to make it have a certain viscosity and ductility.

3. Pressing and molding: The dough is pressed into a certain thickness and shape through an extruder, most commonly in the form of strips or cylinders.

4. Cut into strips: Cut the rolled dough into longer strips, generally the length of spicy strips.

5. Seasoning: According to the ratio, put the corresponding mass of spicy strips and the corresponding mass of seasonings, including seasoning oil and solid seasonings, into a mixing and stirring device. The mixing and stirring device is rotated and stirred to evenly cover the spicy taste and aroma on the surface of the spicy strips.

6. Packaging: The spicy strips need to be packaged after seasoning. It can be packaged automatically by machine or manually.

In the prior art, for the storage and transportation of powders such as flour, the powders are usually stored in a material tank. When the powder is needed, the powder in the material tank enters the screw powder feeder from the discharge port under the action of gravity, and is then sent to the subsequent process. However, during the storage of the powder, the powder in the lower layer is affected by the pressure of the upper layer of powder, as well as static electricity, moisture, etc., and the powder is prone to agglomeration. This not only leads to uneven feeding, but also may block the discharge port of the material tank. Once the discharge port is blocked, the staff needs to clean it, which not only easily causes powder pollution, but also reduces production efficiency. In response to this problem, the prior art, such as the powder discharge device disclosed in the patent of JPS586839A, breaks up the powder by setting a rotating blade inside the material tank. However, since the discharge port and the discharge port of the material tank are arranged in a straight line and the rotation interval of the rotating blade, some of the agglomerated powder fails to contact the rotating blade and directly falls to block the discharge port, or even if it passes through the discharge port, the powder may still remain in a clumped state.

Utility Model Content

The description in this section is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present utility model.

Embodiment 1:

As shown in Figures 1-6, the specific structure of this embodiment is: an anti-agglomeration mechanism of a screw powder feeder, comprising a material tank 1 with an opening at the upper end, a screw powder feeder 2 connected to the interior of the material tank 1 is arranged at the lower end of the material tank 1, a partition 8 adapted to the inner wall of the material tank 1 is arranged in the middle position of the material tank 1, and the material tank 1 is divided into an upper and lower layer by the partition 8, a first rotating blade 6 is rotatably installed at the bottom of the material tank 1, a connecting rod 5 is arranged at the center of the upper end of the first rotating blade 6, and the upper end of the connecting rod 5 passes through the partition 8 and is provided with a second rotating blade The lower end of the second rotating blade 7 is close to the upper end surface of the partition 8, the partition 8 is penetrated by a second through hole 12, the bottom of the material tank 1 is penetrated by a first through hole 10 connected with the screw powder feeder 2, the positions of the first through hole 10 and the second through hole 12 are staggered, a rotating shaft 13 is arranged in the second through hole 12 along the radial direction of the partition 8, and the outer side wall of the rotating shaft 13 is arrayed around its axis with scattering leaves 14, and the distance between the outer end surface of the scattering leaf 14 and the axis of the rotating shaft 13 is greater than the thickness of the partition 8.

Specific working principle: When using this device to convey powder, first start this device and pour the powder into the material tank 1. Driven by the connecting rod 5, the first rotating blade 6 will drive the second rotating blade 7 to rotate synchronously. As the second rotating blade 7 rotates, the powder will be broken up for the first time, and the powder on the upper layer of the partition 8 will fall into the lower layer of the partition 8 through the second through hole 12; during this process, the second rotating blade 7 will touch the breaking blade 14 that is higher than the upper end surface of the partition 8 when rotating, so as to obtain the rotation of the rotating shaft 13. During the rotation of the rotating shaft 13, the breaking blade 14 breaks up the powder at the second through hole 12, and then cuts the powder at the second through hole 12 in multiple directions without increasing the number of driving mechanisms such as motors, so as to further avoid the agglomeration of the powder. A plurality of breaking blades 14 are arranged in a ring around the rotating shaft 13, so as to ensure that there is always an upper end surface of the breaking blade 14 that is higher than the upper end surface of the partition, and the distance between the end surfaces of the breaking blades 14 on the left and right sides of the rotating shaft 13 is less than the inner diameter of the second through hole 12.

Then the powder in the lower layer of the partition 8 will fall into the screw powder feeder 2 from the first through hole 10, and the powder will be transported away by the screw powder feeder 2. During this process, the rotating first rotary blade 6 will cut and break up the agglomeration of the powder for the second time. The positions of the first through hole 10 and the second through hole 12 are staggered to ensure that the powder falling from the second through hole 12 will not directly enter the screw powder feeder 2 through the first through hole 10, but must be cut and broken up by the first rotary blade 6. In the above whole process, the device can completely break up the agglomeration of the powder by layered feeding and multiple cutting when conveying the powder, prevent blockage, and improve production efficiency.
