Description

Technical Field

[0001] The present invention relates to the technical field of transportation, and specifically to a flour production and conveying device. Background Art

[0002] As a light and easily dust - raising powdery material, flour is extremely likely to cause dust pollution during mechanical conveying, affecting the cleanliness of the production environment; the pneumatic conveying system transports flour through closed pipelines and airflows, fundamentally solving these problems and having advantages that cannot be compared with traditional mechanical conveying. By adopting the pneumatic conveying system, flour mills can not only improve production efficiency, reduce costs, but also effectively improve the production environment and ensure product quality.

[0003] Considering that pneumatic conveying is usually used when transporting flour in production, the prior art uses a vacuum pump to suck air during pneumatic transportation, creating a negative pressure in the pipeline and sucking out the flour through the negative pressure to achieve the effect of transporting flour; however, in the prior art, the flour is sucked in a dusty state. At this time, it may generate high temperatures due to the long - time friction of the flour against the pipeline or the long - time use of internal equipment. At the same time, when a device failure causes an open fire, the concentration of dusty flour in the pipeline may be too high, resulting in a dust explosion. Summary of the Invention

An air - inlet pipe is fixedly connected to an outer wall of the air - equalizing disc far from the processing pipe; the air - inlet pipe, the air - equalizing disc, the air - guiding pipes and the processing pipe are all communicated, and the air - inlet pipe is used for inputting helium gas at ten to fifteen degrees Celsius; an outer wall of the air - guiding pipe is fixedly connected to the processing pipe.

[0006] Further, the air guide pipe is arranged obliquely upward from the air equalizing plate to the processing pipe, and an air inlet one-way valve is arranged inside the air guide pipe.

[0007] Further, the suction unit includes an air collecting plate, the air collecting plate is fixedly connected to the outer wall of the processing pipe near the bottom, an air outlet pipe is fixedly connected to the outer wall of the air collecting plate, and one end of the air outlet pipe away from the air collecting plate is connected to a vacuum pump; a filter screen is slidably connected to the outer wall of the air collecting plate in contact with the processing pipe.

[0008] Further, a bracket is fixedly connected to the inner wall of the processing pipe, an impeller is rotatably connected to the bottom of the bracket, and both the impeller and the bracket are located above the filter screen.

[0009] Further, a sliding groove and a reset groove are formed in the inner wall of the processing pipe, the sliding groove is slidably connected to the outer wall of the top of the filter screen, the reset groove is slidably connected to the outer wall of the bottom of the filter screen, and a reset spring is fixedly connected between the reset groove and the filter screen; a pushing block is fixedly connected to the top of the filter screen, and a plurality of stress blocks are fixedly connected to the inner wall of the pushing block; the stress blocks are slidably connected to the sliding groove; a rotating rod is fixedly connected to the outer wall of the bottom of the impeller; the stress blocks are slidably connected to the rotating rod.

[0010] Further, a motor bracket is fixedly connected to the inner wall of the bottom of the processing pipe, a driving motor is arranged on the top of the motor bracket, and a screw conveyor is fixedly connected to the output end of the driving motor, and the screw conveyor is slidably connected to the inner wall of the bottom of the filter screen.

[0011] Further, the filter screen includes two filter membrane frames, and a filter membrane is fixedly connected between the filter membrane frames, and the filter membrane is used for separating flour from air.

[0012] Further, the inner walls of the processing pipe and the conveying pipe are both mirror surfaces.

[0013] The present invention has the following beneficial effects: 1.

When sudden situations such as equipment spontaneous combustion occur, since helium is an inert gas, open flames in the processing pipe can be avoided, thereby increasing the safety of the equipment; since the temperature of the helium introduced into the processing pipe is 10 to 15 degrees Celsius, the temperature in the processing pipe can be reduced, and high temperature in the processing pipe caused by friction or equipment use can be avoided.

[0014] 2. When the present invention encounters caked flour, since the vacuum pump sucks out air, the air in the processing pipe will flow, which can cause the impeller to rotate. Due to the relatively large mass of the caked flour, it will be hit by the impeller and fly out after contacting the impeller, and hit the inner wall of the processing pipe, causing the caked flour to be broken by the impact. When it is broken into small pieces, the moisture can be sucked out through the dryness of helium gas, so that the wet flour can be redried; when the flour is dried, the reproduction of microorganisms can be prevented, thereby prolonging the storage time of the flour.

[0015] 3. When flour adheres to the filter screen, the auger is rotated by starting the drive motor. When the auger rotates, the flour on the filter screen will be scraped off, so that the filter screen can flow. Since the air flow velocity of the filter screen from which the flour has been scraped off is faster, the flour will also be preferentially adsorbed. At this time, the flour can be scraped off again by the auger, and the scraped-off flour will enter the packaging equipment for storage through the inlet one-way valve; the method of repeatedly scraping off the flour by the auger can not only prevent the flour from blocking the filter screen, but also increase the collection efficiency through the repeated adhesion of the flour.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 8 As shown, the present invention is a flour production and delivery device, including a processing pipe 1. An outer wall in the middle of the processing pipe 1 is fixedly connected with a flow-slowing unit 2. An outer wall of the processing pipe 1 near the bottom is fixedly connected with a suction unit 3. An outer wall at the top of the processing pipe 1 is fixedly connected with a plurality of delivery pipes 11; the delivery pipes 11 and the processing pipe 1 are both communicated. One end of the delivery pipe 11 away from the processing pipe 1 is fixedly connected with a collection unit 12. The delivery pipe 11 can face multiple directions; the collection unit 12 is used for collecting the produced flour, the flow-slowing unit 2 is used for slowing down the flow rate of the flour, and the suction unit 3 is used for sucking the flour; a bottom of the processing pipe 1 is fixedly connected with an inlet one-way valve 4. The inlet one-way valve 4 is used to prevent the backflow of the flour, and the inlet one-way valve 4 is connected to a packaging device; The flow-slowing unit 2 includes an air-distributing plate 21. The air-distributing plate 21 is fixedly connected with an outer wall in the middle of the processing pipe 1. A plurality of air guide pipes 22 are fixedly connected to an outer wall of the air-distributing plate 21 that fits the processing pipe 1. An air inlet pipe 23 is fixedly connected to an outer wall of the air-distributing plate 21 away from the processing pipe 1; the air inlet pipe 23, the air-distributing plate 21, the air guide pipes 22 and the processing pipe 1 are all communicated. The air inlet pipe 23 is used for inputting helium gas at 10 to 15 degrees Celsius; an outer wall of the air guide pipe 22 is fixedly connected with the processing pipe 1.

[0021] In this embodiment, considering that pneumatic conveying is usually used in the production and transportation of flour, the prior art uses a vacuum pump to suck air during pneumatic transportation, creating a negative pressure in the pipeline and sucking out the flour through the negative pressure to achieve the effect of transporting flour. However, in the prior art, the flour is sucked in a dust-like state, and at this time, high temperatures may be generated due to the long-term friction of the flour against the pipeline or the long-term use of internal equipment. At the same time, when a device failure causes an open flame, the concentration of the dust-like flour in the pipeline may be too high, resulting in a dust explosion. During use, a negative pressure is formed in the treatment pipe 1 by starting the suction unit 3, and the high air pressure outside the collection unit 12 drives the flour to move, and the flour moves towards the treatment pipe 1 in the conveying pipe 11, thus achieving the effect of sucking the flour. When the flour enters the treatment pipe 1, the air inlet pipe 23 conveys helium into the air equalizing plate 21, and the helium is evenly transmitted into the air guide pipe 22 through the air equalizing plate 21. At this time, the air guide pipe 22 discharges the helium into the interior of the treatment pipe 1. When the helium enters the treatment pipe 1, it reduces the oxygen concentration in the treatment pipe 1. And during long-term suction, all the air in the pipeline is pumped out, leaving only the helium conveyed by the air inlet pipe 23. When emergencies such as equipment self-ignition occur, since helium is an inert gas and there is a lack of oxygen in the treatment pipe 1, the generation of open flames in the treatment pipe 1 can be avoided, thereby increasing the safety of the equipment. Since helium is introduced into the treatment pipe 1 and the temperature of the helium at this time is ten to fifteen degrees Celsius, the temperature in the treatment pipe 1 can be reduced, and the high temperature in the treatment pipe 1 caused by friction or equipment use can be avoided. Since helium can absorb water molecules, when the flour passes through helium, the moisture in the flour can be sucked out, keeping the flour dry. When the flour enters the packaging equipment, some helium will follow the flour into the interior of the packaging equipment and make the helium come into full contact with the flour when packaging the flour. Even after packaging, some helium can be between the flour. Since helium can effectively prevent oxidation, it can also prevent the flour from spoiling and make the flour last longer. At the same time, the dryness of the flour can prevent the reproduction of microorganisms caused by the dampness of the flour, thereby increasing the shelf life of the flour. Due to the use of multiple conveying pipes 11, the suction efficiency can be increased when sucking flour from the same collection unit 12. At the same time, when the pipeline is blocked, other conveying pipes 11 can be used for transportation to avoid the situation where flour cannot be transported. When sucking flour from different directions, the position and direction of the conveying pipe 11 can also be changed, making it more convenient to suck the flour. The conveying pipe can not only be connected to the collection unit 12, but can be directly connected when it is necessary to extract the flour in a large storage tank, avoiding the dust and pollution generated during manual collection.

[0022] Specifically, the air guide pipe 22 is arranged obliquely upward from the air equalizing plate 21 to the processing pipe 1, and an air inlet check valve is arranged inside the air guide pipe 22.

[0023] In this embodiment, considering that the suction unit 3 will cause the flour in the processing pipe 1 to flow at a high speed, which may cause the flour to reach the position of the suction unit 3 too quickly, resulting in blockage. When the flour enters the processing pipe 1, helium gas is blown upward through the air guide pipe 22, so that the flour collides with the helium gas, thereby slowing down the flow rate of the flour. And because the air guide pipes 22 are all arranged obliquely upward, when blowing out the helium gas, the flour can be gathered towards the center of the processing pipe 1, so that the flour is re-aggregated from the powdery state, reducing the concentration of powdery flour. This can not only make the flour entering the packaging equipment sink to the bottom quickly, but also avoid dust explosion caused by too high dust concentration.

[0024] Specifically, the suction unit 3 includes a gas collecting plate 31, the gas collecting plate 31 is fixedly connected to the outer wall of the processing pipe 1 near the bottom, an air outlet pipe 32 is fixedly connected to the outer wall of the gas collecting plate 31, and one end of the air outlet pipe 32 far from the gas collecting plate 31 is connected to a vacuum pump; a filter screen 35 is slidably connected to the outer wall of the gas collecting plate 31 that fits the processing pipe 1.

[0025] In this embodiment, considering that in the prior art, the vacuum pump is usually directly connected to the packaging equipment, and when sucking, the air in the packaging equipment is sucked and the flour is sucked through the negative pressure in the processing pipe. However, when there is flour in the packaging equipment, it may cause the flour in the packaging equipment to be sucked in, which may cause blockage, and may also cause the flour to be affected by the suction of the vacuum pump and unable to sink to the bottom. When sucking the flour, the air in the gas collecting plate 31 is sucked out through the air outlet pipe 32 by the vacuum pump. At this time, the air in the processing pipe 1 is also sucked out, and a negative pressure is formed in the processing pipe 1, so that the flour can be sucked into the processing pipe 1 through the negative pressure; when the vacuum pump sucks out the air, the flour is blocked by the filter screen 35 from being sucked out; since the air in the processing pipe 1 is sucked out and the setting of the feed check valve 4 can prevent the air in the packaging equipment from being sucked out, the flour in the packaging equipment can remain at the bottom instead of in a suspended dust state, and the dust explosion of the powdery flour in the packaging equipment can be avoided.

[0026] Specifically, a bracket 34 is fixedly connected to the inner wall of the processing pipe 1, and an impeller 341 is rotatably connected to the bottom of the bracket 34. The impeller 341 and the bracket 34 are both above the filter screen 35.

[0027] In this embodiment, considering that when storing flour, since there is a large amount of stored flour, the flour at the bottom may be agglomerated due to long-term extrusion. At the same time, some flour may be produced without being completely dried during production, which may cause the flour to come into contact with water and agglomerate. If not treated, the entry of moisture may cause the reproduction of microorganisms, which may accelerate the deterioration of the flour, thus shortening the storage time of the flour. When encountering agglomerated flour, since the vacuum pump sucks out air, the air in the treatment pipe 1 will flow, which can cause the impeller 341 to rotate. When the impeller 341 rotates, the passing flour can slide down along the impeller 341. When encountering agglomerated flour, since the agglomerated flour has a large mass, it will be hit by the impeller 341 and fly out after contacting the impeller 341, and hit the inner wall of the treatment pipe 1, so that the agglomerated flour is broken by the impact. When broken into small pieces, the moisture can be sucked out by the dryness of helium, so that the wet flour can be dried again. When the flour is dried, the reproduction of microorganisms can be prevented, thus lengthening the storage time of the flour.

[0028] Specifically, a sliding groove 38 and a reset groove 381 are formed in the inner wall of the treatment pipe 1. The sliding groove 38 is slidably connected to the outer wall of the top of the filter screen 35, and the reset groove 381 is slidably connected to the outer wall of the bottom of the filter screen 35. A reset spring 37 is fixedly connected between the reset groove 381 and the filter screen 35. A pushing block 36 is fixedly connected to the top of the filter screen 35, and a plurality of stress blocks 361 are fixedly connected to the inner wall of the pushing block 36. The stress block 361 is slidably connected to the sliding groove 38. A rotating rod 342 is fixedly connected to the outer wall of the bottom of the impeller 341. The stress block 361 is slidably connected to the rotating rod 342.

[0029] In this embodiment, considering that the filter screen 35 may be blocked due to the adhesion of flour after sucking flour for a long time. When the filter screen 35 is blocked, the subsequent flour cannot be sucked. When the impeller 341 rotates, it will drive the rotating rod 342 to rotate. When the rotating rod 342 rotates, it will come into contact with the stress block 361. When contacting, the rotating rod 342 will push the stress block 361 downward. When the stress block 361 moves downward, it will drive the pushing block 36 downward. At this time, the pushing block 36 will push the filter screen 35 downward and compress the reset spring 37 by the filter screen 35. When the rotating rod 342 does not contact the stress block 361, the reset spring 37 will reset the filter screen 35. Since there are multiple stress blocks 361, each time the rotating rod 342 contacts and separates from the stress block 361, the filter screen 35 will vibrate once, and the flour on the filter screen 35 will be shaken off, thus preventing the filter screen 35 from being blocked by flour.

[0030] Specifically, a motor bracket 33 is fixedly connected to the inner wall of the bottom of the processing pipe 1. A driving motor is arranged on the top of the motor bracket 33. The output end of the driving motor is fixedly connected with an auger 331, and the auger 331 is slidably connected with the inner wall of the bottom of the filter screen 35.

[0031] In this embodiment, considering that when the efficiency of the vacuum pump for sucking flour is too high, the filter screen 35 may shake and the flour cannot be completely shaken off, so that the filter screen 35 is gradually blocked, resulting in a gradual decrease in the efficiency of sucking flour; When flour adheres to the filter screen 35, the driving motor is started to rotate the auger 331. When the auger 331 rotates, the flour on the filter screen 35 will be scraped off, so that the filter screen 35 is unblocked. Through the shaking of the filter screen 35, the flour above the filter screen 35 will slowly fall off. And because the air flow speed of the filter screen 35 from which the flour has been scraped off is faster, the flour will also be preferentially adsorbed. At this time, the flour can be scraped off again by the auger 331, and the scraped-off flour will enter the packaging equipment for storage through the inlet one-way valve 4; the method of repeatedly scraping off the flour by the auger 331 can not only prevent the flour from blocking the filter screen 35, but also increase the collection efficiency through the repeated adhesion of the flour.

[0032] Specifically, the filter screen 35 includes two filter membrane frames 351, and a filter membrane 352 is fixedly connected between the filter membrane frames 351. The filter membrane 352 is used to separate flour and air.

[0033] In this embodiment, considering that the elasticity of the filter membrane 352 is good, when only the filter membrane 352 is used, the filter membrane 352 will deform towards the air collecting disc 31 due to the air flow, so that the auger 331 cannot scrape off the flour on the filter membrane 352; By arranging the filter membrane frame 351 on the outer layer of the filter membrane 352, the deformation of the filter membrane 352 can be avoided. When the vacuum pump sucks air, the filter membrane frame 351 will prevent the filter membrane 352 from deforming, so that the auger 331 can always scrape off the flour.

[0034] Specifically, the inner walls of the processing pipe 1 and the conveying pipe 11 are both mirror surfaces.

[0035] In this embodiment, when the inner walls of the processing pipe 1 and the conveying pipe 11 are mirror surfaces, the friction between the flour and the pipe wall can be reduced, and the residue of the flour at the gaps of the pipe wall can be reduced.

[0036] When in use, First, when sucking flour, the air in the air collecting tray 31 is sucked out through the air outlet pipe 32 by the vacuum pump. At this time, the air in the treatment pipe 1 is also sucked out, and a negative pressure is formed in the treatment pipe 1, so that the flour can be sucked into the treatment pipe 1 by the negative pressure. When the vacuum pump sucks out air, the flour will be blocked by the filter screen 35 from being sucked out. Since the air in the treatment pipe 1 is sucked out and the setting of the inlet one-way valve 4 can prevent the air in the packaging equipment from being sucked out, the flour in the packaging equipment can be kept at the bottom instead of in a suspended dust state, and the dust explosion of the flour in the form of dust in the packaging equipment can be avoided. Since multiple conveying pipes 11 are used, the sucking efficiency can be increased when sucking flour from the same collecting unit 12. At the same time, when the pipeline is blocked, other conveying pipes 11 can be used for conveying to avoid the situation where flour cannot be conveyed. When sucking flour in different directions, the position and direction of the conveying pipe 11 can also be changed, making it more convenient to suck flour. The conveying pipe can not only be connected to the collecting unit 12, but can be directly connected when it is necessary to extract the flour in a large storage tank, avoiding the dust and pollution generated during manual collection.

[0037] Secondly, when the flour enters the treatment pipe 1, the air inlet pipe 23 will convey helium into the air equalizing tray 21, and the helium will be evenly transferred into the air guide pipe 22 through the air equalizing tray 21. At this time, the air guide pipe 22 will discharge the helium into the interior of the treatment pipe 1. When the helium enters the treatment pipe 1, the oxygen concentration in the treatment pipe 1 will be reduced. And during long-term sucking, the air in the pipeline is completely pumped out, leaving only the helium conveyed by the air inlet pipe 23. When emergencies such as equipment spontaneous combustion occur, since helium is an inert gas and there is a lack of oxygen in the treatment pipe 1, the generation of open flames in the treatment pipe 1 can be avoided, thus increasing the safety of the equipment. Since helium is introduced into the treatment pipe 1 and the temperature of the helium at this time is ten to fifteen degrees Celsius, the temperature in the treatment pipe 1 can be reduced, avoiding the high temperature in the treatment pipe 1 caused by friction or the use of the equipment. Since helium can absorb water molecules, when the flour passes through the helium, the moisture in the flour can be sucked out, keeping the flour dry. When the flour enters the treatment pipe 1, the helium is blown upward through the air guide pipe 22, so that the flour collides with the helium, slowing down the flow rate of the flour. And since the air guide pipes 22 are all inclined upward, when the helium is blown out, the flour can be gathered towards the center of the treatment pipe 1, so that the flour is re-aggregated from the dust state, reducing the concentration of the flour in the form of dust. This can not only make the flour entering the packaging equipment sink to the bottom quickly, but also avoid the dust explosion caused by too high dust concentration.

[0038] Then, when encountering caked flour, since the vacuum pump sucks out air, the air in the processing pipe 1 will flow, which can cause the impeller 341 to rotate. When the impeller 341 rotates, the passing flour can slide down along the impeller 341. When encountering caked flour, due to the relatively large mass of the caked flour, it will be hit and fly out by the impeller 341 after contacting the impeller 341, and hit the inner wall of the processing pipe 1, so that the caked flour is broken by the impact. When broken into small pieces, the moisture can be sucked out through the dryness of helium, so that the wet flour can be dried again; when the flour is dried, the reproduction of microorganisms can be prevented, so that the storage time of the flour becomes longer; When the impeller 341 rotates, it will drive the rotating rod 342 to rotate. When the rotating rod 342 rotates, it will contact the force-receiving block 361. When contacting, the rotating rod 342 will push the force-receiving block 361 downward. When the force-receiving block 361 moves downward, it will drive the pushing block 36 downward. At this time, the pushing block 36 will push the filter screen 35 downward and compress the return spring 37 of the filter screen 35; when the rotating rod 342 does not contact the force-receiving block 361, the return spring 37 will reset the filter screen 35. Since there are multiple force-receiving blocks 361, every time the rotating rod 342 contacts and separates from the force-receiving block 361, the filter screen 35 will vibrate once, and the flour on the filter screen 35 will be shaken off, thus preventing the filter screen 35 from being blocked by flour; When flour adheres to the filter screen 35, the auger 331 is rotated by starting the drive motor. When the auger 331 rotates, the flour on the filter screen 35 will be scraped off, so that the filter screen 35 can flow. Through the vibration of the filter screen 35, the flour above the filter screen 35 will slowly fall off. And because the filter screen 35 from which the flour is scraped has a faster air flow speed, the flour will also be preferentially adsorbed. At this time, the flour can be scraped off again by the auger 331. The scraped flour will enter the packaging equipment through the feed check valve 4 for storage; the method of repeatedly scraping the flour by the auger 331 can not only prevent the flour from blocking the filter screen 35, but also increase the collection efficiency through the repeated adhesion of the flour.

[0039] Finally, when the flour enters the packaging equipment, part of the helium will follow the flour into the interior of the packaging equipment and make the helium fully contact with the flour when packaging the flour. Even after packaging, part of the helium can be between the flour. Since helium can effectively prevent oxidation, it can also prevent the flour from spoiling and make the flour can be stored for a longer time; at the same time, through the dryness of the flour, the reproduction of microorganisms caused by the dampness of the flour can be prevented, thus increasing the shelf life of the flour.
