Technical Field

[0001] The present invention relates to the technical field of rice impurity removal, and particularly relates to a rice processing air separation impurity removal device. Background Art

[0002] Rice is a finished product made after processes such as cleaning, hulling, milling, and finished product packaging of paddy. There are usually many impurities in rice. The impurities that may be contained in rice mainly include the following types: 1. Sand, granular dust, etc.: These impurities may be mixed in during the processes of planting, harvesting, packaging, and transportation; 2. Plant debris such as rice husks and leaves: These impurities may not be completely removed during the processes of washing, dehulling, and grinding; 3. Other debris, such as small insects and molds.

[0003] The publicly disclosed Chinese patent No. CN208437234U discloses a rice processing air separation impurity removal device, which includes an equipment box, a suction fan, a coarse sieve plate, a fine sieve plate, a rack, a sector gear, a driving motor, a turntable, and a control panel. This device can extract the dust in rice through the suction fan, and screen and remove the remaining impurities through the coarse sieve plate and the fine sieve plate.

[0004] When the above-mentioned prior art uses air separation for impurity removal, mainly when the rice is falling, the air blown by the fan is used to remove impurities from the rice during the falling process. This device has the following problems: Since the impurities in the rice are of various types, including lighter impurities such as rice husks and leaves, although these impurities can be blown out of the rice by the wind during the falling process of the rice, due to the fast falling speed of the rice and the fact that these impurities are sandwiched between the rice grains, the rice has a blocking effect on them, resulting in some impurities not being selected by air separation, and the impurity removal effect is not ideal. Summary of the Invention

[0005] (1) Invention Objectives

[0006] In view of this, the objective of the present invention is to provide a rice processing air separation impurity removal device. The technical problem to be solved is that since the impurities in the rice are of various types, including lighter impurities such as rice husks and leaves, although these impurities can be blown out of the rice by the wind during the falling process of the rice, due to the fast falling speed of the rice and the fact that these impurities are sandwiched between the rice grains, the rice has a blocking effect on them, resulting in some impurities not being selected by air separation, and the impurity removal effect is not ideal.

[0019] As can be seen from the above technical solutions, the present application has the following beneficial effects:

[0020] 1: In the present invention, after some rice accumulates inside the annular baffle and on the filter screen, the blower is started, and the air blown by it is conveyed through the air duct to the impurity removal pipe, and then blown out from above the impurity removal pipe. As a result, the lighter impurities in the rice inside the filter screen, such as leaves and rice husks, are blown out from above the annular baffle. After these lighter impurities are blown out, they will fall into the impurity removal box and finally be discharged from the impurity leakage groove.

[0021] 2: In the present invention, the second motor is started to drive the cylindrical barrel, the cylindrical rod, the L-shaped bracket, the annular baffle, and the filter screen to rotate. When the filter screen rotates and the second hemispherical plate at its bottom abuts against the first hemispherical plate, the filter screen is squeezed and moves upward, driving the annular baffle, the L-shaped bracket, the first motor box, and the cylindrical rod to move upward. When the cylindrical rod moves upward, it squeezes the spring. When the second hemispherical plate and the first hemispherical plate are misaligned, the annular baffle and the filter screen are driven to move downward under the resilience of the spring. Repeating this way makes the rice inside the filter screen and the annular baffle fluctuate and vibrate. During the fluctuation process, the rice and impurities are separated, enabling the lighter impurities, such as leaves and rice husks, to be more easily blown out by the air blown by the blower. Moreover, other impurities, such as sand and granular dust, fall from the filter screen into the rectangular barrel and onto the folding plate.

[0022] 3: In the present invention, when the rice is subjected to air separation, the folding plate is horizontally arranged. At this time, the folding plate seals the rectangular barrel, so that the air blown by the blower will only flow upward after being conveyed through the air duct to the impurity removal pipe, enabling the air to remove the lighter impurities in the rice. At this time, other impurities in the rice, such as sand and dust, will fall from the filter screen onto the folding plate. Then, the fourth motor is started to drive the second rotating rod to rotate. When the second rotating rod rotates, it drives the folding plate to rotate. When the folding plate rotates to an inclined position, the impurities on it will be discharged from the impurity discharge cylinder. At this time, the material distribution plate seals the rice discharge cylinder.

[0023] 4: In the present invention, after the air separation of the rice is completed, the fifth motor is started to drive the third rotating rod to rotate. When the third rotating rod rotates, it drives the material distribution plate to rotate, so that the material distribution plate seals the impurity discharge cylinder. At this time, the rice discharge cylinder opens. Then, the third motor is started to drive the first rotating rod, the connecting disk, the connecting rod, and the annular baffle to rotate. When the second rice discharge slot on the annular baffle rotates to coincide with the first rice discharge slot, the third motor stops working. Then, the second motor is started and its speed is increased, so that the clean rice after air separation on the filter screen falls from the second rice discharge slot and the first rice discharge slot into the impurity removal pipe under the action of centrifugal force, and then falls from the rectangular barrel into the rice discharge cylinder and is discharged.

[0038] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that mutually excludes other embodiments.

[0039] Furthermore, the present invention is described in detail with reference to the schematic diagrams.

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0040] Refer to Figures 1-10 :

[0041] For an embodiment of the present invention, a rice processing air separation and impurity removal device is provided, which includes a main body unit 100 and an impurity removal unit 200. The main body unit 100 includes an impurity removal box 101. A plurality of impurity leakage grooves 102 are formed at the bottom of the impurity removal box 101. A rectangular cylinder 103 is fixed to the bottom of the impurity removal box 101. One end of the rectangular cylinder 103 extending outside the impurity removal box 101 is fixed and communicated with an impurity discharge cylinder 104 and a rice discharge cylinder 105. An impurity removal pipe 106 is fixed and communicated with the top of the rectangular cylinder 103. An air guide pipe 107 is fixed to one side of the impurity removal box 101, and one end of the air guide pipe 107 extending into the impurity removal box 101 is fixed and communicated with the impurity removal pipe 106. A blower 108 is installed inside one end of the air guide pipe 107. Support feet are fixed to the four corners of the bottom of the impurity removal box 101. A feeding assembly is arranged at the top of the impurity removal box 101. The impurity removal unit 200 includes a filter screen 201. An annular enclosing plate 202 is fixed to the outside of the filter screen 201. The filter screen 201 and the annular enclosing plate 202 are located inside the impurity removal pipe 106. A plurality of L-shaped brackets 203 are fixed to the annular enclosing plate 202 at equal intervals along its radial direction. A first motor box 204 is arranged above the annular enclosing plate 202. One end of the L-shaped bracket 203 away from the annular enclosing plate 202 is fixed to the first motor box 204. A control assembly for controlling the up and down vibration of the filter screen 201 is arranged below the annular enclosing plate 202.

[0042] Among them, the feeding assembly includes a rice guiding pipe 111 fixed to the top of the impurity removal box 101, and the discharge port of the rice guiding pipe 111 is located above the filter screen 201. A conical rice cylinder 110 is fixed and communicated with the top of the rice guiding pipe 111. A rice storage cylinder 109 is fixed and communicated with the top of the conical rice cylinder 110. A partition plate 112 is fixed to the bottom of the rice storage cylinder 109. A circular baffle 113 is arranged on the partition plate 112. The circular baffle 113 rotates inside the rice storage cylinder 109. A support plate 117 is fixed to the top of the rice storage cylinder 109. A first motor 118 is installed on the top of the support plate 117. A rotating shaft 116 is fixed to the top of the circular baffle 113. The top of the rotating shaft 116 is fixed to the output end of the first motor 118. A plurality of second feeding holes 115 are formed in the circular baffle 113. A plurality of first feeding holes 114 corresponding to the second feeding holes 115 are formed in the partition plate 112.

[0043] During use, first pour the rice that needs to remove impurities into the rice storage cylinder 109, and then start the first motor 118 to drive the rotation of the rotating shaft 116. When the rotating shaft 116 rotates, it drives the rotation of the circular baffle 113. When the second material discharge hole 115 rotates to coincide with the first material discharge hole 114, the first motor 118 stops working. At this time, the rice in the rice storage cylinder 109 will fall from the second material discharge hole 115 and the first material discharge hole 114 into the conical rice cylinder 110, and then be conveyed from the conical rice cylinder 110 into the rice guiding pipe 111. After that, the rice is conveyed through the rice guiding pipe 111 into the annular baffle 202 and placed on the filter screen 201. After conveying a part of the rice, the first motor 118 works again to drive the circular baffle 113 to rotate again, so that the second material discharge hole 115 and the first material discharge hole 114 are misaligned. At this time, the conveyance of the rice stops. When some rice accumulates in the annular baffle 202 and on the filter screen 201, start the blower 108. When the blower 108 is started, the blown air is conveyed through the air guiding pipe 107 into the impurity removal pipe 106, and then the air blows out from above the impurity removal pipe 106, so that the air blows out the lighter impurities in the rice in the filter screen 201, such as leaves, rice husks, etc., from above the annular baffle 202. After these lighter impurities are blown out, they will fall into the impurity removal box 101 and finally be discharged from the impurity leakage groove 102.

[0044] In addition, a second rotating rod 223 is rotatably connected inside the rectangular cylinder 103. A folding plate 224 is fixed on the outer side of the second rotating rod 223. The folding plate 224 can seal the rectangular cylinder 103. A second motor box 225 is fixed on the outer side of the rectangular cylinder 103. A fourth motor 226 is installed inside the second motor box 225. One end of the second rotating rod 223 extending outside the rectangular cylinder 103 is fixed to the output end of the fourth motor 226. A third rotating rod 227 is rotatably connected to the bottom of the rectangular cylinder 103. A material distributing plate 228 is fixed on the outer side of the third rotating rod 227. The material distributing plate 228 can seal the impurity discharge cylinder 104 or the cylindrical rod 205. A fifth motor 229 is installed on the outer side of the rectangular cylinder 103. One end of the third rotating rod 227 extending outside the rectangular cylinder 103 is fixed to the output end of the fifth motor 229.

[0045] Specifically, the control component includes an annular sleeve 230. A plurality of sector plates 231 are fixedly arranged at equal intervals along the radial direction on the outer side of the annular sleeve 230. One end of the sector plate 231 away from the annular sleeve 230 is fixed to the inner wall of the impurity removal pipe 106. A first hemispherical plate 232 is fixed to the top of the sector plate 231. A plurality of second hemispherical plates 233 are fixed to the bottom of the filter net 201. A guide post 234 is fixed to the bottom of the filter net 201. The guide post 234 is slidably engaged in the annular sleeve 230. A cylindrical rod 205 is fixed to the top of the first motor box 204. A protection pipe 206 is fixed to the inner wall of the top of the impurity removal box 101. The cylindrical rod 205 penetrates through the protection pipe 206 and is slidably located inside the protection pipe 206. A cylindrical cylinder 207 is rotatably connected to the top of the impurity removal box 101, and the cylindrical cylinder 207 is located inside the protection pipe 206. A second motor 209 is installed on the top of the impurity removal box 101. The top of the cylindrical cylinder 207 is fixed to the output end of the second motor 209.

[0046] It should be noted that due to the arrangement of the annular sleeve 230 and the guide post 234, when the filter net 201 and the annular enclosure 202 fluctuate up and down, the annular sleeve 230 moves up and down accordingly inside the guide post 234. In this process, the guide post 234 plays a role in limiting, enabling the filter net 201 and the annular enclosure 202 to move up and down stably.

[0047] Furthermore, the cylindrical rod 205 is slidably engaged in the cylindrical cylinder 207. A plurality of limit grooves 210 are formed inside the cylindrical cylinder 207. A plurality of limit blocks 211 are fixed to the outer side of the cylindrical rod 205. The plurality of limit blocks 211 are respectively slidably engaged in the corresponding limit grooves 210. A spring 212 is arranged inside the cylindrical cylinder 207. One end of the spring 212 abuts against the inner wall of the cylindrical cylinder 207, and the other end of the spring 212 abuts against the cylindrical rod 205.

[0048] During use, start the second motor 209 to drive the cylindrical barrel 207 to rotate. When the cylindrical barrel 207 rotates, it drives the cylindrical rod 205 to rotate. When the cylindrical rod 205 rotates, it drives the L-shaped bracket 203 to rotate. When the L-shaped bracket 203 rotates, it drives the annular baffle 202 and the filter screen 201 to rotate. When the filter screen 201 rotates and the second hemispherical plate 233 at its bottom abuts against the first hemispherical plate 232, the filter screen 201 is squeezed and moves upward, and drives the annular baffle 202 and the L-shaped bracket 203 to move upward. When the L-shaped bracket 203 moves upward, it drives the first motor box 204 and the cylindrical rod 205 to move upward. When the cylindrical rod 205 moves upward, it will squeeze the spring 212. During this process, the limit block 211 will move in the limit groove 210. When the second hemispherical plate 233 and the first hemispherical plate 232 are misaligned, at this time, the cylindrical rod 205 is driven to move downward by the resilience of the spring 212, and then drives the annular baffle 202 and the filter screen 201 to move downward. After that, when the second hemispherical plate 233 squeezes the first hemispherical plate 232 again, it drives the filter screen 201 to move upward. Repeating this way, the rice in the filter screen 201 and inside the annular baffle 202 fluctuates and vibrates, avoiding the mixing of impurities and rice in the rice, which is not convenient for removal. During the up and down vibration and fluctuation of the rice, the rice and impurities are separated during the vibration and fluctuation process, so that lighter impurities, such as leaves and rice husks, can be more easily blown out by the wind of the blower 108, and other impurities, such as sand and granular dust, fall from the filter screen 201 into the rectangular barrel 103 and onto the folding plate 224.

[0049] In addition, an annular baffle 217 is provided inside the annular baffle 202, and the outer side of the annular baffle 217 is fitted to the inner wall of the annular baffle 202. The annular baffle 217 rotates inside the annular baffle 202. A plurality of first rice outlet grooves 216 are equidistantly arranged along the diameter of the annular baffle 202. A plurality of second rice outlet grooves 218 corresponding to the first rice outlet grooves 216 are equidistantly arranged along the diameter of the annular baffle 217. A third motor 222 is installed in the first motor box 204. The bottom of the first motor box 204 is rotatably connected to a first rotating rod 221. The top of the first rotating rod 221 is fixed to the output end of the third motor 222. A connecting disk 219 is fixed to the bottom of the first rotating rod 221. A plurality of connecting rods 220 are equidistantly fixed along the diameter of the outer side of the connecting disk 219, and the end of the connecting rod 220 away from the connecting disk 219 is fixed to the annular baffle 217. The axes of the annular sleeve 230, the guide post 234, the filter screen 201, the annular baffle 202, the first motor box 204, the first rotating rod 221, the cylindrical rod 205, and the cylindrical barrel 207 coincide.

[0050] In use, after the rice winnowing is completed, first start the fifth motor 229 to drive the third rotating rod 227 to rotate. When the third rotating rod 227 rotates, it drives the material dividing plate 228 to rotate, so that the material dividing plate 228 seals the impurity discharge cylinder 104. At this time, the rice discharge cylinder 105 is opened. Then start the third motor 222 to drive the first rotating rod 221 to rotate. When the first rotating rod 221 rotates, it drives the connecting disk 219 and the connecting rod 220 to rotate. When the connecting rod 220 rotates, it drives the annular baffle 217 to rotate. When the second rice outlet groove 218 on the annular baffle 217 rotates to coincide with the first rice outlet groove 216, at this time the third motor 222 stops working. Then start the second motor 209 and increase its speed. It should be noted that initially when winnowing the rice, the second motor 209 rotates slowly, so that the rice on the filter net 201 will not accumulate at the edge of the filter net 201, that is, the rice is basically laid flat on the filter net 201, which is convenient for winnowing the rice. And during this process, the speed of the second motor 209 is increased, so that the clean rice winnowed on the filter net 201 falls into the impurity removal pipe 106 under the centrifugal force from the second rice outlet groove 218 and the first rice outlet groove 216, and then falls into the rice discharge cylinder 105 from the rectangular cylinder 103 and is discharged. It should be noted that there is a conveying pipeline for other rice connected to the rice discharge cylinder 105 to convey the clean rice to a designated storage container to avoid being contaminated again.

[0051] It is worth adding that when winnowing the rice, the folding plate 224 is horizontally arranged. At this time, the folding plate 224 seals the rectangular cylinder 103, so that the wind blown by the fan 108 is only upward after being conveyed to the impurity removal pipe 106 through the air duct 107, so that the wind removes the lighter impurities in the rice. At this time, other impurities in the rice, such as sand, dust, etc. will fall from the filter net 201 onto the folding plate 224. Then start the fourth motor 226 to drive the second rotating rod 223 to rotate. When the second rotating rod 223 rotates, it drives the folding plate 224 to rotate. When the folding plate 224 rotates to an inclined position, the impurities on it will be discharged from the impurity discharge cylinder 104. At this time, the material dividing plate 228 seals the rice discharge cylinder 105.

[0052] It should be noted that the fan 108, the second motor 209, the first motor 118, the second motor box 225, the third motor 222, and the fifth motor 229 in this embodiment are all conventional devices well-known to those skilled in the art and can be purchased on the market. The model can be selected according to actual needs or customized. In this patent, we only use them and do not improve their structures and functions. For those skilled in the art, their setting methods, installation methods, and electrical connection methods only need to be debugged and operated according to the requirements of their user manuals, and will not be elaborated here. Moreover, the fan 108, the second motor 209, the first motor 118, the second motor box 225, the third motor 222, and the fifth motor 229 are all provided with control switches matching them, and the installation positions of the control switches are selected according to actual use requirements, as long as it is convenient for the operator to operate and control.
