Description

Technical Field

[0001] This utility model relates to the field of pneumatic feed conveying technology, and in particular to a pneumatic feed conveying system. Background Technology

[0002] The traditional way to feed ruminants is to transport pellets and powders to the pasture by truck and then pour them into the feed hoppers of their respective feed inlets.

[0003] For example, pelleted feed flows down the feed hopper onto the scraper conveyor below. The conveyor transfers the feed to the feed inlet of the elevator, which then lifts the feed to a certain height. The feed flows out from the discharge end of the elevator, and the pellets flow onto the conveyor installed on the pellet steel silo, where they enter the silo. Concentrated feed (powdered feed) is similar to pelleted feed. After being lifted to a certain height by the elevator, the concentrated feed is transferred from the discharge outlet to the material distributor via a chute. The distributor distributes the concentrated feed to different silos, and the concentrated feed from the distributor is then transported to the silos via a chute, thus realizing the feed transportation.

[0004] This type of conveying method has the following disadvantages: First, it requires a large investment, including a low-level conveyor (for conveying feed from the feed hopper), two elevators, and elevator towers; second, the equipment is complex and the control system is relatively cumbersome; third, there are many pieces of equipment, which are prone to failure and have high maintenance costs; fourth, because the chain of the scraper conveyor cannot be lubricated with lubricating oil, and the scraper and the bottom plate are dry friction, the lifespan is relatively short. Utility Model Content

[0005] To address the problems of high cost, cumbersome control, and short service life of current scraper conveyor systems, this utility model provides a pneumatic feed conveying system.

[0006] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0007] A pneumatic feed conveying system includes a hopper, with a rotary feeder connected to the hopper's discharge port. The outlet of the rotary feeder is connected to a side wall of a conveying pipe. One end of the conveying pipe is connected to a blower, and the end of the conveying pipe away from the blower is connected to a distributor. The distributor has several discharge ports. One discharge port is connected to a second distributor via a second conveying pipe, and the remaining discharge ports are connected to a pellet silo. The second distributor has several discharge ports, which are connected to a concentrate feed silo. Compared to a scraper conveyor system, this pneumatic feed conveying system reduces the need for large equipment such as low-level conveyors, elevators, and elevator towers. This pneumatic feed conveying system utilizes airflow generated by a blower to convey feed. The blower has relatively low energy consumption, and there are no high-wear parts like those in a scraper conveyor during the conveying process, reducing the increased operating costs caused by frequent component replacements. The blower only requires adjustment of air volume and pressure, the rotary feeder speed can be easily set according to the conveying capacity, and distributor one and distributor two can be switched to corresponding discharge ports one and two. The control system is relatively simple, easy to operate and maintain, reducing the technical threshold and training costs for operators. Under normal airflow conveying conditions, the wear of conveying pipes one and two is far lower than the wear between the scraper and the bottom plate of a scraper conveyor, thus greatly extending the service life of the entire pneumatic feed conveying system, reducing equipment replacement frequency, and lowering long-term operating costs.

[0008] Preferably, the rotary feeder includes a housing; a rotating shaft is rotatably mounted inside the housing; several distribution plates are evenly arranged along the circumference on the outer wall of the rotating shaft; one end of the rotating shaft passes through the housing and is connected to a motor. The housing provides stable protection and a mounting base for the internal components. The rotating shaft can rotate flexibly within the housing, and the several distribution plates evenly arranged along the circumference on it can evenly divide and quantitatively transport the feed falling from the hopper to the conveying pipe during rotation, effectively ensuring the stability and uniformity of feed conveying. The motor is connected to the rotating shaft, providing power for its rotation. By adjusting the speed of the motor, the feed feeding speed can be precisely controlled to meet the feed conveying requirements under different working conditions, thus improving the overall efficiency and reliability of the feed pneumatic conveying system.

[0009] Preferably, a gap is provided between the feed distribution plate and the housing. This gap effectively prevents the feed distribution plate from colliding and rubbing against the housing during high-speed rotation, significantly reducing noise and wear during operation and extending the service life of the rotary feeder. Simultaneously, this gap allows the feed to flow more smoothly under the push of the feed distribution plate, preventing feed jamming due to excessive tightness between the plate and housing, ensuring the stability and continuity of the feeding process, and guaranteeing the stable and efficient operation of the pneumatic feed conveying system.

[0010] Preferably, the feed distributor includes a housing; several discharge ports are disposed on the housing; a feed inlet is disposed at one end of the housing; a rotating shaft is rotatably disposed inside the housing; several short pipes are fixedly disposed on the rotating shaft along the circumferential direction; the feed inlet can connect to the discharge ports through the short pipes; a motor is connected to one end of the rotating shaft after passing through the housing. The housing, as the main support structure, provides a stable installation space for the feed inlet, discharge ports, and internal rotating components. The rotating shaft rotates flexibly inside the housing, and the several short pipes fixedly disposed on it along the circumferential direction become the key channels for feed diversion. By driving the rotating shaft to rotate through the motor, the connection status between the feed inlet and different discharge ports can be precisely controlled, realizing the diversion of feed to the pellet silo as needed or further flowing to the feed distributor through the conveying pipe, thus providing a solution for the classification, storage, and precise distribution of feed.

[0011] Preferably, the second shell is cylindrical in shape; the first inlet is located at one axial end of the second shell; the other axial end of the second shell has a first outlet; two first outlets are located on the peripheral wall of the second shell; the short pipe includes a straight pipe and two bends; the first inlet can connect to the first first outlet on the axial side of the second shell through the straight pipe; the first inlet can connect to the first first outlet on the peripheral wall of the second shell through the bends. The first inlet being located at one axial end of the second shell facilitates concentrated feed intake. The first outlets located at the other axial end and on the peripheral wall of the second shell, combined with the short pipe structure consisting of a straight pipe and two bends, greatly expand the flexibility of feed distribution. When feed needs to be transported to storage bins in different locations, the rotating shaft is driven by motor two to rotate. The feed inlet one can be connected to the discharge outlet one at the other end of the shaft through a straight pipe, or connected to the discharge outlet one on the circumferential wall through a curved pipe. This accurately and efficiently diverts the feed to multiple discharge outlets one in different directions and locations, fully meeting the diverse feeding needs of the pneumatic feed conveying system and improving the smoothness and efficiency of the entire conveying process.

[0012] Preferably, the feed distributor 2 includes a housing 3; a feed inlet 2 is provided at the middle of one axial end of the housing 3; a connecting pipe is rotatably mounted on the feed inlet 2; a rotating shaft 3 is provided on the side wall of the connecting pipe; the end of the rotating shaft 3 away from the connecting pipe passes through the housing 3 and is connected to a motor 3; a plurality of discharge ports 2 are evenly arranged circumferentially on the side wall of the housing 3 away from the feed inlet 2. The feed inlet 2 is located at the middle of one axial end of the housing 3, which facilitates the centralized input of feed. The connecting pipe rotates on the feed inlet 2, and in conjunction with the rotating shaft 3 driven by the motor 3, the conveying direction of the feed can be flexibly adjusted. When the motor 3 operates, driving the rotating shaft 3 and the connecting pipe to rotate, the feed entering from the feed inlet 2 can be accurately guided to the plurality of discharge ports 2 evenly arranged circumferentially on the side wall of the housing 3 away from the feed inlet 2. This design greatly improves the accuracy and efficiency of distributing concentrate feed to different concentrate feed bins, and can better adapt to the needs of the feed pneumatic conveying system for diversified and precise distribution of concentrate feed, ensuring the high efficiency and stability of the entire system operation.

[0013] Preferably, the centerline of the connecting pipe is set in an S-shaped arc. This effectively buffers the impact force when feed enters, avoiding equipment wear caused by high-speed feed impact and extending the service life of the connecting pipe and the second distributor. During the conveying process, the S-shaped arc design guides the feed to a gentle change direction, making the feed flow more uniform and stable, reducing the risk of blockage, and ensuring that the concentrate feed can be continuously and efficiently conveyed to each discharge port. At the same time, this design helps to reduce the noise generated during feed conveying, optimizes the working environment, and further improves the overall operating quality of the feed pneumatic conveying system.

[0014] Preferably, the outer wall of the housing is provided with support legs to provide stable support for the feeder.

[0015] Preferably, a cyclone separator is installed on the pellet silo; the discharge port is connected to the cyclone separator.

[0016] Preferably, a second cyclone separator is installed on the feed silo; the second discharge port is connected to the second cyclone separator. The first and second cyclone separators efficiently separate the pelleted feed transported by the airflow from the air. The air-feed mixture entering from the first and second discharge ports rotates at high speed within the first and second cyclone separators. Due to its greater weight, the pelleted feed is thrown against the inner wall by centrifugal force and slides into the pellet silo and feed silo, while the air is discharged from the top of the first and second cyclone separators. This not only achieves precise collection and storage of pelleted feed and feed, preventing pelleted feed from escaping with the airflow and causing waste, but also avoids environmental pollution from residual pelleted feed in the air, greatly improving the environmental friendliness and economy of the feed conveying process, and ensuring the high efficiency and stability of the feed pneumatic conveying system.

[0017] The beneficial effects of this utility model are:

[0018] The hopper, equipped with a rotary feeder, accurately and stably delivers feed into the conveying pipe, preventing feed accumulation and blockage. A blower powers the entire system, using airflow to transport feed, resulting in lower energy consumption and smoother operation compared to traditional scraper conveyors. Distributor 1 has multiple outlets, some directly connected to the pellet hopper for rapid distribution and storage of pellets; another outlet connects to distributor 2 via conveying pipe 2, enabling secondary precise distribution of concentrate feed. Distributor 2 connects to various concentrate feed hoppers, ensuring that concentrate feed is delivered as needed. This entire system effectively solves the problems of high cost, cumbersome control, and short service life of traditional scraper conveyor systems, significantly improving feed conveying efficiency, reducing operating costs, and ensuring efficient, stable, and precise feed delivery.

[0028] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1 and Figure 2 As shown, a pneumatic feed conveying system includes a hopper 1, with a rotary feeder 2 connected to the feed inlet of the hopper 1. The outlet of the rotary feeder 2 is connected to the side wall of a conveying pipe 3. One end of the conveying pipe 3 is connected to a blower 4, and the end of the conveying pipe 3 away from the blower 4 is connected to a distributor 5. The distributor 5 has several discharge ports 501. One discharge port 501 is connected to a distributor 7 via a conveying pipe 6, and the remaining discharge ports 501 are connected to a pellet hopper 8. The distributor 7 has several discharge ports 701. The discharge ports 701 are connected to a concentrate feed hopper 9. A cyclone separator 10 is installed on the pellet hopper 8, and the discharge ports 501 are connected to the cyclone separator 10. A cyclone separator 11 is installed on the concentrate feed hopper 9, and the discharge ports 701 are connected to the cyclone separator 11.

[0031] Compared to scraper conveyor systems, this pneumatic feed conveying system reduces the need for large equipment such as low-level conveyors, elevators, and elevator towers. This system utilizes airflow generated by blower 4 to transport feed. Blower 4 has relatively low energy consumption and lacks high-wear parts like those in scraper conveyors, reducing operating costs associated with frequent component replacements. Blower 4 only requires adjustment of airflow and pressure. The rotation speed of rotary feeder 2 can be easily set according to the conveying volume. Distributor 1 5 and distributor 2 7 can be switched to corresponding discharge ports 1 501 and 2 701. The control system is relatively simple, easy to operate and maintain, lowering the technical threshold and training costs for operators. Under normal airflow conveying conditions, the wear on conveying pipes 1 3 and 2 6 is far lower than the wear between the scraper and the base plate of a scraper conveyor, significantly extending the service life of the entire pneumatic feed conveying system, reducing equipment replacement frequency, and lowering long-term operating costs. Shakelon separators 1 10 and 2 11 efficiently separate the pelleted material transported by the airflow from the air. The air-feed mixture entering from outlet 501 and outlet 701 rotates at high speed within cyclone separators 10 and 11. Due to their greater weight, the pellets are thrown against the inner wall by centrifugal force and slide into pellet bin 8 and concentrate bin 9, while the air is discharged from the top of cyclone separators 10 and 11. This not only achieves precise collection and storage of pellets and concentrates, preventing pellets from escaping with the airflow and causing waste, but also avoids environmental pollution from residual pellets in the air, greatly improving the environmental friendliness and economy of the feed conveying process and ensuring the high efficiency and stability of the feed pneumatic conveying system.

[0032] like Figure 3 As shown, the rotary feeder 2 includes a housing 201; a rotating shaft 202 is rotatably disposed inside the housing 201; a plurality of material distribution plates 203 are evenly disposed on the outer wall of the rotating shaft 202 along the circumferential direction; one end of the rotating shaft 202 passes through the housing 201 and is connected to a motor 204. A gap is provided between the material distribution plates 203 and the housing 201.

[0033] The housing 201 provides a stable protection and mounting base for the internal components. The rotating shaft 202 can rotate flexibly within the housing, and several feed distribution plates 203 evenly arranged along its circumference can evenly divide and quantitatively transport the feed falling from the hopper 1 to the conveying pipe 3 during rotation, effectively ensuring the stability and uniformity of feed delivery. The motor 204 connects to the rotating shaft 202, providing power for its rotation. By adjusting the speed of the motor 204, the feed feeding speed can be precisely controlled to meet the feed delivery requirements under different working conditions, thus improving the overall efficiency and reliability of the feed pneumatic conveying system. A gap is provided between the feed distribution plates 203 and the housing 201 to effectively prevent hard collisions and friction between the feed distribution plates 203 and the housing 201 during high-speed rotation, greatly reducing noise and wear during equipment operation and extending the service life of the rotary feeder 2. Meanwhile, the existence of this gap allows the feed to flow more smoothly under the push of the feed distribution plate 203, preventing feed jamming caused by the feed distribution plate 203 and the shell 201 being too tightly attached, ensuring the stability and continuity of the feeding process, and ensuring the stable and efficient operation of the feed pneumatic conveying system.

[0034] like Figure 4 and Figure 5 As shown, the feeder 5 includes a housing 502; several discharge ports 501 are provided on the housing 502; a feed inlet 503 is provided at one end of the housing 502; a rotating shaft 504 is rotatably provided inside the housing 502; several short pipes are fixedly provided on the rotating shaft 504 along the circumferential direction; the feed inlet 503 can be connected to the discharge port 501 through the short pipes; a motor 507 is connected to one end of the rotating shaft 504 after passing through the housing 502. The second housing 502 is generally cylindrical; the first inlet 503 is located at one end of the second housing 502 along the axial direction; the other end of the second housing 502 along the axial direction is provided with a first outlet 501; two first outlets 501 are provided on the peripheral wall of the second housing 502; the short pipe includes a straight pipe 505 and two bent pipes 506; the first inlet 503 can be connected to the first outlet 501 along the axial direction of the second housing 502 through the straight pipe 505; the first inlet 503 can be connected to the first outlet 501 on the peripheral wall of the second housing 502 through the bent pipes 506.

[0035] The housing 502 serves as the main support structure, providing stable installation space for the feed inlet 503, the discharge outlet 501, and internal rotating components. The rotating shaft 504 rotates flexibly within the housing, and several short pipes fixed along its circumference form key channels for feed distribution. Driven by the motor 507, the rotation of the rotating shaft 504 allows for precise control of the connection between the feed inlet 503 and different discharge outlets 501, enabling feed to be distributed as needed to the pellet hopper 8 or further to the distributor 7 via the conveying pipe 6. This provides a solution for the classified storage and precise distribution of feed. The feed inlet 503 is located at one axial end of the housing 502, facilitating concentrated feed entry. Discharge outlets 501 are located at the other axial end of the housing 502 and on its circumferential wall, working in conjunction with a short pipe structure consisting of a straight pipe 505 and two bent pipes 506, greatly expanding the flexibility of feed distribution. When feed needs to be transported to storage bins in different locations, the rotating shaft 504 is driven by the motor 507 to rotate. The feed inlet 503 can be connected to the discharge outlet 501 at the other end of the shaft through the straight pipe 505, or to the discharge outlet 501 on the circumferential wall through the bent pipe 506. This accurately and efficiently diverts the feed to multiple discharge outlets 501 in different directions and locations, fully meeting the diverse feeding needs of the pneumatic feed conveying system and improving the smoothness and efficiency of the entire conveying process.

[0036] like Figure 6 and Figure 7 As shown, the feeder 2 7 includes a housing 3 702; a feed inlet 2 703 is provided at the middle of one axial end of the housing 3 702; a connecting pipe 704 is rotatably mounted on the feed inlet 2 703; a rotating shaft 3 705 is provided on the side wall of the connecting pipe 704; the end of the rotating shaft 3 705 away from the connecting pipe 704 passes through the housing 3 702 and is connected to a motor 3 706; several discharge ports 2 701 are evenly arranged circumferentially on the side wall of the end of the housing 3 702 away from the feed inlet 2 703. The center line of the connecting pipe 704 is arranged in an S-shaped arc. Support legs 707 are provided on the outer wall of the housing 3 702.

[0037] Feed inlet 2 703 is located at the middle of one axial end of housing 3 702, facilitating centralized feed input. Connecting pipe 704 rotates on feed inlet 2 703, cooperating with rotating shaft 3 705 driven by motor 3 706 to flexibly adjust the feed conveying direction. When motor 3 706 rotates, driving rotating shaft 3 705 and connecting pipe 704, the feed entering from feed inlet 2 703 is precisely guided to several discharge outlets 2 701 evenly distributed circumferentially on the side wall of housing 3 702 away from feed inlet 2 703. This design greatly improves the accuracy and efficiency of distributing concentrate feed to different concentrate feed bins 9, better adapting to the needs of pneumatic feed conveying systems for diversified and precise concentrate feed distribution, ensuring the high efficiency and stability of the entire system. The reasonable setting of the centerline of connecting pipe 704 effectively buffers the impact force when feed enters, avoiding equipment wear caused by high-speed feed impact, and extending the service life of connecting pipe 704 and distributor 2 7. During the conveying process, the S-shaped arc design guides the feed to a gentle turn, making the feed flow more uniform and stable, reducing the risk of blockage, and ensuring that the concentrate feed can be continuously and efficiently delivered to each discharge port. At the same time, this design helps reduce the noise generated during feed conveying, optimizes the working environment, and further improves the overall operational quality of the feed pneumatic conveying system.
