Description

Technical Field

[0001] This utility model relates to the field of feed conveying technology, specifically to a feed conveying device with powder separation function. Background Technology

[0002] The work of a feed processing worker includes receiving, cleaning, storing, crushing, batching, mixing, conditioning, expanding, pelleting, extrusion puffing, drying, crushing, screening, liquid addition and spraying, packaging, ventilation and dust removal, pneumatic conveying, etc. The feed needs to be conveyed through conveying devices of different structures to ensure that the feed processing technology can be carried out continuously.

[0003] In the feed preparation and production process, some feed raw materials need to be screened and then transported to the next production point. In this process, both screening and transportation require independent equipment, which results in a large footprint and reduced production efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a feed conveying device with powder separation function, including a hollow outer shell with an inner cavity. The inner wall of the outer shell is fixed with a partition plate with an arc-shaped cross-section. The inner cavity of the outer shell is divided into a first screening chamber and a second screening chamber by the partition plate. A plurality of sieve holes are evenly penetrated through the partition plate. The first screening chamber and the second screening chamber are interconnected through the sieve holes. The top of the outer shell is integrally equipped with a feed pipe that communicates with the first screening chamber and is used for feeding. The bottom of the outer shell is integrally equipped with a first discharge pipe that communicates with the first screening chamber and a second discharge pipe that communicates with the second screening chamber. The first screening chamber is provided with a first conveying component that moves the feed entering through the feed pipe to the first discharge pipe for discharge. The second screening chamber is provided with a second conveying component that moves the feed falling into the second screening chamber through the sieve holes to the second discharge pipe for discharge.

[0005] To achieve the above objectives, feed poured in through the feed pipe enters the first screening chamber and falls onto the partition. Feed particles smaller than the sieve holes pass through the sieve holes and enter the second screening chamber. The feed is screened and separated by the partition. The feed in the first screening chamber is transported to the first discharge pipe by the first conveying component, and the feed in the second screening chamber is transported to the second discharge pipe by the second conveying component. This achieves the function of screening and separating feed during the conveying process, reducing costs and the required floor space, and improving production efficiency.

[0006] Furthermore, the first conveying assembly includes a first connecting shaft disposed within the first screening chamber and rotatably connected to the inner cavity wall of the outer shell. The centerline of the first connecting shaft coincides with the centerline of the partition. A spiral-shaped first conveying blade adapted to the first screening chamber is coaxially fixed to the outer circumferential wall of the first connecting shaft.

[0007] The above technical solution uses an integrated first connecting shaft and a first conveying blade to facilitate the conveying of feed entering the first screening chamber to the first discharge pipe.

[0008] Furthermore, the second conveying assembly includes a second connecting shaft disposed in the second screening chamber and rotatably connected to the inner cavity wall of the housing. The second connecting shaft is located directly below the first connecting shaft. A spiral-shaped second conveying blade adapted to the second screening chamber is coaxially fixed on the outer circumferential wall of the second connecting shaft. The housing is provided with a power assembly for driving the first connecting shaft and the second connecting shaft to rotate.

[0009] Through the above technical solution, the power component provides power to drive the first connecting shaft and the second connecting shaft to rotate. The short shafts of the first connecting shaft and the second connecting shaft will drive the first conveying blade, which is integrated with the first connecting shaft, and the second conveying blade, which is integrated with the second connecting shaft, to rotate, thereby discharging the screened and separated feed through the first discharge pipe and the second discharge pipe respectively.

[0010] Furthermore, one end of both the first connecting shaft and the second connecting shaft extends out of the housing and is rotatably connected to the housing. The power assembly includes a motor fixedly connected to the housing. The output shaft end of the motor is nested with a synchronous pulley A fixed to the motor output shaft. The synchronous pulley A is coaxially fixed to the portion of the second connecting shaft that extends out of the housing. The portion of the first connecting shaft that extends out of the housing is coaxially nested with a synchronous pulley B fixed to the first connecting shaft. The synchronous pulleys A and B are fitted with a synchronous belt that cooperates with the synchronous pulleys A and B.

[0011] Through the above technical solution, the motor provides power to drive the A synchronous pulley, which is coaxially fixed with the motor output shaft, to rotate. The A synchronous pulley, the synchronous belt, and the B synchronous pulley work together to transmit power, which drives the second connecting shaft, which is coaxially fixed with the A synchronous pulley, and the first connecting shaft, which is coaxially fixed with the B synchronous pulley, to rotate, thereby driving the first conveying blade and the second conveying blade to rotate.

[0012] Furthermore, a number of hard bristles are fixed on the side of the first conveying blade away from the first connecting shaft and the side of the second conveying blade away from the second connecting shaft. The hard bristles fixed to the first conveying blade are in contact with the bottom and wall of the first screening chamber, and the hard bristles fixed to the second conveying blade are in contact with the bottom and wall of the second screening chamber.

[0013] The above technical solution, combined with hard bristles, improves feed conveying efficiency while reducing the possibility of feed clogging the screen holes and extending the service life of the baffle.

[0014] Furthermore, the end of the feed pipe away from the outer shell is integrally equipped with a feed hopper, and the inner wall of the feed hopper is fixed with a slowing plate. The slowing plate is provided with a feeding component to distribute the feed entering the feed pipe to slow down the speed at which the feed enters the first screening chamber.

[0015] By using the above technical solution, a slowing plate is set on the feed hopper, and a distributing component is set on the slowing plate, the speed at which feed enters the first screening chamber is reduced, thus reducing the possibility of too much feed entering the first screening chamber too quickly and affecting the screening and separation effect.

[0016] Furthermore, the material distribution assembly includes several material distribution plates fixed on the buffer plate, and several circular protrusions for guiding the material are also fixed on the buffer plate, and the material distribution plates and circular protrusions are arranged in an array.

[0017] The above technical solution uses a feed distribution plate and circular protrusions to divert the feed poured onto the slowing plate, allowing the feed to be evenly dispersed and enter the first screening chamber.

[0018] In summary, this feed conveying device with powder separation function has the following beneficial effects:

[0019] (1) The feed conveying device with powder separation function is used to feed the feed poured in by the feed pipe into the first screening chamber and fall on the partition plate. The feed with a particle size smaller than the screen hole will pass through the screen hole and enter the second screening chamber. The feed is screened and separated by the partition plate. The feed in the first screening chamber is conveyed to the first discharge pipe by the first conveying component and discharged by the second conveying component. The feed in the second screening chamber is conveyed to the second discharge pipe by the second conveying component, so as to realize the function of screening and separating feed during the conveying process, reduce cost and required floor space, and improve production efficiency.

[0020] (2) The feed conveying device with powder separation function improves feed conveying efficiency and reduces the possibility of feed clogging the screen holes by using hard bristles, thus increasing the service life of the partition.

[0021] (3) The feed conveying device with powder separation function reduces the speed at which feed enters the first screening chamber by setting a slowing plate on the feed hopper and setting a distributing component on the slowing plate, thereby reducing the possibility that too much feed will enter the first screening chamber too quickly and affect the screening and separation effect.

[0029] The technical solution of this utility model will be more clearly and completely explained below with reference to the accompanying drawings and through the description of the preferred embodiments of this utility model.

[0030] like Figure 1-5 As shown, the preferred embodiment of this utility model provides a feed conveying device with powder separation function, comprising a hollow outer shell 1. An arc-shaped partition 2 is fixed in the middle of the inner wall of the outer shell 1. The inner cavity of the outer shell 1 is divided into a first screening chamber 3 and a second screening chamber 4 by the partition 2. A plurality of sieve holes 5 are evenly distributed through the partition 2. The first screening chamber 3 and the second screening chamber 4 are interconnected only through the sieve holes 5. An integrated feed pipe 6, communicating with the first screening chamber 3 and used for feeding, is integrally formed at the top of the outer shell 1. An integrated first discharge pipe, also communicating with the first screening chamber 3, is integrally formed at the bottom of the outer shell 1. 7 and a second discharge pipe 8 connected to the second screening chamber 4. The first discharge pipe 7 passes through the partition 2 and is connected to the first screening chamber 3. The top of the first discharge pipe 7 is flush with the inner wall of the partition 2. The second discharge pipe 8 enters the second screening chamber 4. The top of the second discharge pipe 8 entering the second screening chamber 4 is flush with the bottom of the inner wall of the second screening chamber 4. The first screening chamber 3 is provided with a first conveying component that moves the feed entering through the feed pipe 6 to the first discharge pipe 7 for discharge. The second screening chamber 4 is provided with a second conveying component that moves the feed falling into the second screening chamber 4 through the screen hole 5 to the second discharge pipe 8 for discharge.

[0031] like Figure 4Feed poured in through the feed pipe 6 enters the first screening chamber 3 and falls onto the partition plate 2. Feed particles smaller than the sieve holes 5 pass through the sieve holes 5 and enter the second screening chamber 4. The feed is screened and separated by the partition plate 2. The feed in the first screening chamber 3 is transported to the first discharge pipe 7 by the first conveying component and discharged by the second conveying component. The feed in the second screening chamber 4 is transported to the second discharge pipe 7 by the second conveying component. This achieves the function of screening and separating feed during the conveying process, reducing costs and the required floor space, and improving production efficiency.

[0032] like Figure 4 The first conveying assembly includes a first connecting shaft 9 disposed in the first screening chamber 3 and rotatably connected to the inner cavity wall of the outer shell 1. The center line of the first connecting shaft 9 coincides with the center line of the partition 2. A spiral-shaped first conveying blade 10 adapted to the first screening chamber 3 is coaxially fixed on the outer circumference of the first connecting shaft 9. The first conveying blade 10 is close to the partition 2. The first connecting shaft 9 and the first conveying blade 10, which are integrated, cooperate to facilitate the conveying of feed entering the first screening chamber 3 to the first discharge pipe 7 for discharge.

[0033] like Figure 4 The second conveying assembly includes a second connecting shaft 11 disposed in the second screening chamber 4 and rotatably connected to the inner cavity wall of the outer shell 1. The second connecting shaft 11 is located directly below the first connecting shaft 9. A spiral-shaped second conveying blade 12 adapted to the second screening chamber 4 is coaxially fixed on the outer circumferential wall of the second connecting shaft 11. The bottom of the outer shell 1 is arc-shaped and adapted to the second conveying blade 12. The second conveying blade 12 is close to the bottom of the outer shell 1. The outer shell 1 is provided with a power assembly that drives the first connecting shaft 9 and the second connecting shaft 11 to rotate. The power assembly provides power to drive the first connecting shaft 9 and the second connecting shaft 11 to rotate. The short shafts of the first connecting shaft 9 and the second connecting shaft 11 will drive the first conveying blade 10, which is integrated with the first connecting shaft 9, and the second conveying blade 12, which is integrated with the second connecting shaft 11, to rotate, thereby discharging the screened and separated feed through the first discharge pipe 7 and the second discharge pipe 8, respectively.

[0034] like Figure 1 One end of the first connecting shaft 9 and the second connecting shaft 11 both protrude from the outer shell 1 and are rotatably connected to the outer shell 1. The power assembly includes a motor 13 fixedly connected to the outer shell 1. The output shaft end of the motor 13 is nested with a synchronous pulley A 14 fixed to the output shaft of the motor 13. The synchronous pulley A 14 is coaxially fixed to the part of the second connecting shaft 11 that protrudes from the outer shell 1. The part of the first connecting shaft 9 that protrudes from the outer shell 1 is coaxially nested with a synchronous pulley B 15 that is coaxially fixed to the first connecting shaft 9. The synchronous pulley A 14 and the synchronous pulley B 15 are covered with a synchronous belt 16 that cooperates with the synchronous pulley A 14 and the synchronous pulley B 15.

[0035] like Figure 1Power is provided by motor 13, which drives synchronous pulley A 14, which is coaxially fixed with the output shaft of motor 13, to rotate. Through synchronous pulley A 14, synchronous belt 16 and synchronous pulley B 15, power is transmitted to drive the second connecting shaft 11, which is coaxially fixed with synchronous pulley A 14, and the first connecting shaft 9, which is coaxially fixed with synchronous pulley B 15, to rotate, thereby driving the first conveying blade 10 and the second conveying blade 12 to rotate.

[0036] like Figure 4 Several hard bristles are fixed on the side of the first conveying blade 10 away from the first connecting shaft 9 and the side of the second conveying blade 12 away from the second connecting shaft 11. The hard bristles fixed to the first conveying blade 10 contact the bottom and wall of the inner cavity of the first screening chamber 3, and the hard bristles fixed to the second conveying blade 12 contact the bottom and wall of the inner cavity of the second screening chamber 4. Through the cooperation of the hard bristles, the feed conveying efficiency is improved, while the possibility of feed clogging the screen holes 5 is reduced, and the service life of the partition 2 is increased.

[0037] like Figure 3 and Figure 5 The feed pipe 6 has an integrated feed hopper 17 at the end away from the outer shell 1. A slowing plate 18 is fixed to the inner wall of the feed hopper 17. The slowing plate 18 is arranged at an angle, and there is a gap between the rear end of the slowing plate 18 and the feed hopper 17. The slowing plate 18 is equipped with a feeding component to distribute the feed entering the feed pipe 6 and slow down the speed at which the feed enters the first screening chamber 3. By setting the slowing plate 18 on the feed hopper 17 and the feeding component on the slowing plate 18, the speed at which the feed enters the first screening chamber 3 is reduced, and the possibility of too much feed entering the first screening chamber 3 too quickly and affecting the screening and separation effect is reduced.

[0038] like Figure 3 and Figure 5 The feeding assembly includes several feeding plates 19 fixed on the buffer plate 18. Several circular protrusions 20 for guiding the feed are also fixed on the buffer plate 18. The feeding plates 19 and the circular protrusions 20 are arranged in an array. By setting the feeding plates 19 and the circular protrusions 20, the feed poured on the buffer plate 18 is diverted, so that the feed falling on the buffer plate 18 is evenly dispersed and enters the first screening chamber 3.

[0039] When in use, connect the power supply and turn on the switch. The operator pours the feed onto the slowing plate 18. The slowing plate 18 is located inside the feed hopper 17. The feed will not be ejected from the feed hopper 17 due to hitting the slowing plate 18. The slowing plate 18 is arranged at an angle. The feed falling on the slowing plate 18 moves towards the distribution plate 19 under the action of gravity. Under the diversion action of the distribution plate 19 and the circular protrusion 20, the feed is evenly dispersed and enters the feed pipe 6 and the first screening chamber 3 through the gap between the slowing plate 18 and the distribution hopper, reducing the possibility of too much feed entering the first screening chamber 3 and affecting the screening and separation effect.

[0040] When motor 13 is turned on, power is provided by motor 13, which drives synchronous pulley A 14, which is coaxially fixed with the output shaft of motor 13, to rotate. The rotation of synchronous pulley A 14 will drive synchronous belt 16, which is sleeved on and cooperates with synchronous pulley A 14, to rotate. The rotation of synchronous belt 16 will drive synchronous pulley B 15, which is set inside and cooperates with synchronous belt 16, to rotate. The rotation of synchronous pulley A 14 will drive second connecting shaft 11, which is coaxially fixed with synchronous pulley A 14, to rotate. The rotation of second connecting shaft 11 will drive second conveying blade 12, which is fixed with second connecting shaft 11, to rotate. The rotation of synchronous pulley B 15 will drive first connecting shaft 9, which is coaxially fixed with synchronous pulley B 15, to rotate. The rotation of first connecting shaft 9 will drive first conveying blade 10, which is fixed with first connecting shaft 9, to rotate.

[0041] The rotation of the first conveying blade 10 will transport the feed entering the first screening chamber 3 toward the first discharge pipe 7 and discharge it through the first discharge pipe 7. Through the action of the partition 2 and the screen hole 5, the feed smaller than the screen hole 5 will pass through the screen hole 5 and enter the second screening chamber 4. The rotation of the second conveying blade 12 will transport the feed entering the second screening chamber 4 toward the second discharge pipe 8 and discharge it through the second discharge pipe 8, so as to realize the screening and separation of feed while it is being transported.

Various modifications, substitutions, and improvements made by those skilled in the art to the technical solutions of the present invention based on the provided description and drawings, without departing from the design concept and spirit of the present invention, should all fall within the scope of protection of the present invention.
