Description

Technical Field

[0001] The utility model provides a flour purifier, which belongs to the technical field of flour processing equipment, and particularly relates to a flour purifier for a flour milling workshop. Background Art

[0002] A flour purifier is a type of grain processing machinery that separates pure and relatively pure endosperm particles from the material ground by a flour mill. It is equipped with air ducts, air chambers, etc., which can loosen the material entering the flour purifier and roughly divide it into three layers according to specific gravity, particle shape, surface properties and aerodynamic characteristics. The light bran is sucked away, and the endosperm with skin is output as the oversize material and sent to the flour mill for recirculation to remove the endosperm particles with skin; the pure and relatively pure endosperm particles enter the flour mill as the undersize material and are further ground into flour.

[0003] After the initial grinding of flour, during the transportation to the flour purifier, flour may become lumpy or sticky, which may result in the flour not being able to be blown away and separated by the fan after entering the flour purifier. The overall distribution may also be uneven, and the light bran may be entrained and unable to be separated with the help of airflow. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] like Figure 1 and Figure 2 As shown, the utility model provides a flour milling workshop powder cleaning machine, comprising a separation bin 1, a plurality of evenly distributed diamond-shaped roller shafts 11 are arranged inside the separation bin 1, a driving motor 15 is connected to the end of the driving shaft 12 away from the connecting frame 14, the driving motor 15 is externally sleeved with an outer shell 16 fixedly connected to the separation bin 1, the roller shaft 11 is internally connected to a fan box 2 arranged on one side of the roller shaft 11 through the driving shaft 12, the driving shaft 12 is externally sleeved with a fixing rod 13 penetrating the roller shaft 11, and the fixing rod 13 is fixedly sleeved with connecting frames 14 penetrated by the driving shaft 12 and fixedly connected on both sides.

[0027] In this embodiment, by setting a roller 11 mounted on a fixed rod 13, when the flour that has been initially processed is put into the separation bin 1 at a uniform speed, the flour falls and washes the diamond-shaped roller 11, causing it to rotate on the fixed rod 13. With the help of the free rotation of multiple rollers 11, the dough blocks are broken up. At the same time, the roller 11 rotates on the drive shaft 12 along with the connecting frame 14, so that the flour is dispersed more evenly, and the blowing separation is achieved with the help of the fan box 2.

[0028] like Figure 3 and Figure 4As shown, a driving gear 21 disposed inside the fan box 2 is sleeved on the driving shaft 12, and the driving gear 21 is connected to a gear groove 23 disposed on the inner side wall of the fan box 2 through a transmission gear 22 evenly distributed around itself, and a plurality of ventilation holes 24 penetrating the fan box 2 are provided on one side of the fan box 2 close to the driving motor 15, and a plurality of evenly distributed fan blades 25 are provided on the other plate of the fan box 2, the fan box 2 penetrates the outer shell 16 and is penetrated by the driving shaft 12, a feeding port 17 corresponding to the roller 11 is provided above the separation bin 1, a first screen 18 penetrating the separation bin 1 is provided at one end of the separation bin 1 away from the fan box 2, and a second screen 19 penetrating the separation bin 1 and corresponding to the position of the feeding port 17 is provided below the separation bin 1.

[0029] In the present embodiment, when the driving motor 15 is started, it drives the driving gear 21 to rotate, thereby driving the transmission gears 22 around it. The transmission gear 22 drives the fan box 2 to rotate with the help of the gear slot 23. The fan blades 25 on the fan box 2 rotate to generate airflow. At this time, the connecting frame 14 and the driving roller 11 are rotating. When flour is put in, the light bran can be separated with the help of the first screen 18. The second screen 19 is used to separate pure and relatively pure endosperm particles.

[0030] When in use, first, turn on the drive motor 15, which will start the operation of the entire device through the drive shaft 12; the flour that has been initially processed is evenly put into the separation bin 1 through the feeding port 17 located above the separation bin 1; the put-in flour will be washed onto the diamond-shaped roller 11 during the falling process. Since the roller 11 is provided on the fixed rod 13, the washing of the flour makes the roller 11 rotate freely on the fixed rod 13, and the dough pieces are broken up by this rotation; the roller 11 rotates on the drive shaft 12 along with the connecting frame 14, and this rotation makes the flour more evenly dispersed; the drive motor 15 simultaneously drives the drive gear 21 located inside the fan box 2 to rotate. The driving gear 21 drives the fan box 2 to rotate via the transmission gear 22 and the gear slot 23; the fan blades 25 on the fan box 2 generate airflow as the fan box 2 rotates, and the airflow is output through the ventilation holes 24 on the fan box 2, which helps to further blow away and separate the flour; in the separation bin 1, as the flour is blown away, the light bran will be screened and separated by the first screen 18; the purer endosperm particles and other heavier parts will continue to fall and be further screened and separated by the second screen 19 arranged below the separation bin 1; the different products after screening (light bran, pure endosperm particles, etc.) will be collected and processed through their respective corresponding outlets.

[0031] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
