Detailed Description
The utility model will be further described with reference to the drawings and examples.
As shown in fig. 1 to 3, the blower 2 for sucking impurities and bran for a rice mill of the present utility model includes a blower housing 21, a main shaft 22, a first centrifugal fan blade 23 and a second centrifugal fan blade 24, and along the axial direction of the blower housing 21, the inner cavity of the blower housing 21 is divided into a feeding chamber 13, a first air chamber 14 and a second air chamber 15 by a first partition 11 and a second partition 12 in sequence. One end of the main shaft 22 penetrates through the second partition plate 12 and is rotatably connected with the second partition plate 12 and extends into the second air chamber 15, and the other end of the main shaft penetrates through the first partition plate 11, passes through the feeding chamber 13 and is rotatably connected with the fan housing 21 and extends out of the fan housing 21. The end of the main shaft 22 extending out of the fan housing 21 may be provided with a belt pulley as required. The first centrifugal fan blade 23 is mounted on the main shaft 22 and is located in the first air chamber 14, and the second centrifugal fan blade 24 is mounted on the main shaft 22 and is located in the second air chamber 15. The first partition plate 11 is provided with an inner feed inlet 111 opposite to the center of the first centrifugal fan blade 23, the side surface of the fan shell 21 is provided with a first feed inlet 16 communicated with the feed chamber 13, a first discharge outlet 17 communicated with the first air chamber 14 and a second discharge outlet 18 communicated with the second air chamber 15, and the end surface of the fan shell 21 is provided with a second feed inlet 19 opposite to the center of the second centrifugal fan blade 24.
Specifically, the first partition 11 and the second partition 12 may be connected to the blower housing 21 by welding or bolting, etc. so as to be disposed in the inner cavity of the blower housing 21.
The principle of the fan for sucking impurities and bran of the rice mill is the same as that of the conventional centrifugal fan, the main shaft 22 is driven to rotate by the driving device, the main shaft 22 drives the first centrifugal fan blade 23 and the second centrifugal fan blade 24 to rotate together in the rotating process, under the action of the first centrifugal fan blade 23, a stream of air flow entering from the inner feed inlet 111 and then being discharged from the first discharge outlet 17 can be generated in the first air chamber 14, and under the action of the second centrifugal fan blade 24, a stream of air flow entering from the second feed inlet 19 and then being discharged from the second discharge outlet 18 can be generated in the second air chamber 15. Since the side surface of the blower housing 21 is provided with the first feeding port 16 communicating with the feeding chamber 13, after the air flow in the first air chamber 14 flows out, the external air flow can enter the inner feeding port 111 from the first feeding port 16 through the feeding chamber 13. Thus, the first inlet 16 can be used for absorbing and separating impurities from rice, while the second inlet 19 can be used for sucking bran.
Because the fan of the rice mill 1 is generally driven by the belt of the driving motor 3 of the rice mill, the fan for sucking impurities and bran of the rice mill needs to be arranged along the axial direction of the driving motor 3 in order to facilitate the driving of the driving motor 3. As shown in fig. 4, if two centrifugal fans 6 are simply connected in series to form a fan 2 for sucking impurities and bran of a rice mill, since an air inlet pipe 5 of the centrifugal fan can only be connected from the end of the fan, a belt pulley 7 for driving the two fans needs to be arranged between the two fans, which causes the problem that the transmission structure of the rice mill is inconvenient to arrange and complicated. In addition, the air inlet pipes are connected from the end of the fan, and the length of the rice mill is increased in the axial direction of the driving motor 3. All of the above factors adversely affect the miniaturization of the rice mill. As shown in fig. 5, the fan for rice husking machine impurity and bran sucking is provided with a first partition plate 11 and a second partition plate 12 in a fan shell 21 to divide the inner cavity of the fan shell 21 into a feeding chamber 13, a first air chamber 14 and a second air chamber 15 in sequence, and a first feeding port 16 communicated with the feeding chamber 13 is arranged on the side surface of the fan shell 21, so that an air inlet pipe 5 for winnowing rice impurities is connected with the fan for rice husking machine impurity and bran sucking from the side surface of the fan shell 21, the fan for rice husking machine impurity and bran sucking can drive a main shaft 22 from one end of the fan for rice husking machine impurity and bran sucking fan, the main shaft 22, a rice husking device 4 and the driving end of a driving motor 3 are conveniently arranged on a vertical line, the rice husking machine is convenient to arrange a driving structure, and the driving structure can be simplified. In addition, the air inlet pipe 5 for winnowing rice impurities can be connected with the fan from the side face of the fan shell 21, so that the length of the fan for sucking impurities and chaff of the rice mill is conveniently shorter, and the rice milling device 4 which is shorter and smaller can be matched. Therefore, the blower for sucking impurities and bran of the rice mill is beneficial to miniaturization of the rice mill.
In the present utility model, the main shaft 22 is rotatably connected to the fan housing 21 and the second partition 12 via bearings, respectively. Of course, the main shaft 22 may be directly rotatably connected to the fan housing 21 and the second partition 12.
The first feed opening 16 and the first discharge opening 17 may be provided at the same side or different sides of the blower housing, and optimally, the first feed opening 16 is provided at one side of the blower housing 21 and the first discharge opening 17 is provided at the other side of the blower housing 21 for convenience of piping arrangement.
As shown in fig. 1, in the embodiment of the present utility model, a bran suction pipe 25 with one end communicating with the second feed inlet 19 is disposed at the second feed inlet 19, the other end of the bran suction pipe 25 is opened to form a rice bran feed inlet 252, and a bran shell feed inlet 251 is disposed on the upper side of the bran suction pipe 25. The bran shell feed inlet 251 is used for extracting bran shells in the rice milling chamber of the rice milling device 4, and the bran feed inlet 252 is used for extracting fine bran in rice.
The utility model also provides a rice mill 1, which adopts the fan for sucking impurities and bran. The first feed inlet 16 of the fan for sucking impurities and bran of the rice mill is connected with the air inlet pipe 5 for winnowing rice impurities of the rice mill, and the second feed inlet 19 is communicated with a rice milling chamber of the rice milling device through a bran sucking pipe 25. After the rice mill adopts the fan for sucking impurities and bran of the rice mill, the main shaft 22, the rice milling device 4 and the driving end of the driving motor 3 are conveniently arranged on a vertical line, so that the rice mill is convenient to arrange a transmission structure, and the transmission structure can be simplified. In addition, the air inlet pipe 5 for winnowing rice impurities can be connected with the fan from the side face of the fan shell 21, so that the length of the fan for sucking impurities and chaff of the rice mill is conveniently shorter, and the rice milling device 4 which is shorter and smaller can be matched. Therefore, the rice mill adopting the above structure can be more compact.
