Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall also fall within the scope of protection of the present application.

[0024] As Figures 1-5 shown, an embodiment of the present application provides a wheat flour impact loosening machine, which includes a first impact bin 1 and a second impact bin 2. The first impact bin 1 is arranged at a position corresponding to the upper vertical direction of the second impact bin 2, and the two are connected and fixed through a conical pipe 10 in the shape of an inverted cone. The pipe orifice at the lower end of the conical pipe 10 is communicated with the feed pipe 11 at the center of the top surface of the second impact bin 2. A spiral pipe 12 is sleeved on the conical pipe 10. The discharge port 13 at the side end of the first impact bin 1 is communicated with the upper pipe orifice of the spiral pipe 12, and the lower pipe orifice of the spiral pipe 12 is tangentially inserted into the side wall of the conical pipe 10.

[0025] During use, materials enter the interior through the feed pipe 11 on the first impact bin 1, and are first impacted for the first time in the first impact bin 1. After being loosened and pulverized, they are ejected from the discharge port 13 on the first impact bin 1. The materials ejected from the discharge port 13 on the first impact bin 1 enter the conical pipe 10 along the spiral pipe 12, and then enter the second impact bin 2 downward through the feed pipe 11 communicated with the lower pipe orifice, and are impacted and loosened for the second time in the second impact bin 2. The wheat flour materials after being impacted, loosened and pulverized twice are finally discharged from the discharge port 13 at the side end of the second impact bin 2.

[0026] In this embodiment, after the wheat flour material is first impacted in the first impact bin 1, it is discharged along the spiral pipe 12 through the discharge port 13 on the first impact bin 1 into the conical pipe 10, and then enters the second impact bin 2 through the pipe orifice at the lower end of the conical pipe 10 from the feed pipe 11 for secondary impact and loosening. The loosened and pulverized wheat flour material is discharged from the discharge port 13 on the side end of the second impact bin 2. By subjecting the wheat flour material to two impact and powder loosening operations in the first impact bin 1 and the second impact bin 2, the flakes of the wheat flour can be further pulverized, the separation effect between the endosperm and the bran can be enhanced, and the flour yield can be increased.

[0027] In a possible implementation manner, the structures of the first impact bin 1 and the second impact bin 2 are the same, and each is composed of a circular housing 3 and a cover body 4 provided at the upper end. A turntable 5 is rotatably connected to the bottom inside the housing 3, and a plurality of rotors 6 are vertically fixed on the turntable 5. A plurality of stators 7 are vertically fixed at the lower end of the cover body 4. The rotors 6 and the stators 7 are alternately distributed in the circumferential direction, and when the rotor 6 rotates around the center of the turntable 5, it can pass through the gap between the stators 7. The discharge port 13 is tangentially provided at the side end of the housing 3, and the feed pipe 11 is vertically communicated with the center of the top surface of the cover body 4.

[0028] During impact, rotating the turntable 5 can cause the rotor 6 to rotate at a high speed inside the housing 3. The material entering the housing 3 through the cover body 4 from the feed pipe 11 lands on the center of the turntable 5 and is thrown outwards by the centrifugal force generated by the rotation of the turntable 5. During the process of the wheat flour material being thrown from the center to the periphery inside the housing 3, it impacts and loosens with the rotor 6 and the stator 7. The loosened and pulverized material is discharged from the discharge port 13 tangentially provided at the side end of the housing 3.

[0029] In a possible implementation manner, a threaded rod 8 is vertically fixed at the top of the stator 7, and the threaded rod 8 passes through the cover body 4 and is fixed by a nut 9.

[0030] The stator 7 is fixed to the cover body 4 through the threaded rod 8, which is convenient for disassembly and replacement.

[0031] In a possible implementation manner, a motor 14 is installed at the bottom of the second impact bin 2. The rotating shaft 15 vertically fixed on the output shaft of the motor 14 passes through the second impact bin 2 and the conical pipe 10 from the center and extends into the first impact bin 1 to drive the first impact bin 1 and the second impact bin 2.

[0032] By installing a single motor 14 at the bottom of the second impact bin 2, the first impact bin 1 and the second impact bin 2 can be driven to operate, and the entering wheat flour material can be subjected to two impact and powder loosening operations.

[0033] In a possible implementation manner, a separation cover 16 with an opening facing downwards is provided at the upper center inside the conical pipe 10, and the upper end of the separation cover 16 is communicated with an air pipe 17 extending through the side wall of the conical pipe 10.

[0034] The pipe orifice at the lower end of the spiral pipe 12 is tangentially inserted into the side wall of the conical pipe 10. The wheat flour material in the spiral pipe 12 can enter the conical pipe 10 tangentially, and a swirling flow is formed in the conical pipe 10. The swirling wheat flour passes downward along the inner wall of the conical pipe 10 and enters the second impact bin 2 through the feed pipe 11 communicated with the pipe orifice at the lower end. The bran impurities overflowing upward in the center of the conical pipe 10 enter the separation hood 16 and are discharged through the air pipe 17.

[0035] In a possible implementation manner, a blower 18 for pressurizing and feeding into the conical pipe 10 is installed on the spiral pipe 12.

[0036] The blower 18 can pressurize and accelerate the wheat flour material entering the conical pipe 10 tangentially along the spiral pipe 12, enhance the centrifugal action of the wheat flour and impurities in the conical pipe 10, and improve the swirling effect of the wheat flour material after entering the conical pipe 10.

[0037] In a possible implementation manner, blades 19 for increasing the rotation speed are installed on the part of the rotating shaft 15 located in the conical pipe 10.

[0038] The rotating shaft 15 drives the blades 19 to rotate in the direction of the swirling flow, which can further enhance the swirling effect of the wheat flour material in the conical pipe 10 and improve the separation efficiency.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
