Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of fodder pneumatic conveying, particularly relates to a mixed concentrate fodder dense-phase pneumatic conveying system. BACKGROUND

[0002] The traditional feeding mode of ruminant feed is that a truck transports granular material and powder to a pasture and pours them into the feeding hoppers of respective feeding ports. The granular material feed flows into the underlying scraper conveyor along the feeding hopper, the conveyor transmits the feed to the feeding port of the elevator, the elevator lifts the feed to a certain height, the feed flows out of the discharge end of the elevator, the granular material flows to the conveyor installed on the granular material steel silo, and the conveyor enters the steel silo. The concentrate feed (powder feed) is similar to the granular material, the concentrate feed is lifted to a certain height by the elevator, and the concentrate feed is transmitted to the material distributor through the chute from the discharge port, the distributor distributes the concentrate feed to different silos, and the concentrate feed from the distributor is conveyed to the silo through the chute to realize the conveying of the feed.

[0003] Such conveying mode has the following disadvantages: 1. large investment, requiring a low-position (feed discharged from the transmission feeding hopper) conveyor, two elevators, an elevator tower, etc.; 2. complex equipment composition and relatively complicated control system; 3. more equipment, prone to faults, and high maintenance cost; and 4. the chain of the scraper conveyor cannot be lubricated with lubricating oil, and the scraper and the bottom plate rub dryly, resulting in short service life. UTILITY MODEL CONTENT

[0004] In view of the problems of high cost, complicated control, and short service life caused by the current scraper conveying system, the utility model provides a mixed concentrate fodder dense-phase pneumatic conveying system.

[0005] To solve the above problems, the utility model adopts the technical scheme that:

[0006] A dense-phase pneumatic conveying system for mixed concentrate feed includes a concentrate feed silo, a screw conveyor connected to the lower outlet of the concentrate feed silo, a weighing silo connected to the outlet of the screw conveyor, a temporary storage silo connected to the outlet of the weighing silo, a pneumatic conveying pump connected to the temporary storage silo, a silo silo connected to the outlet of the pneumatic conveying pump via a pipeline, and a mixer connected to the outlet of the silo. The screw conveyor, in conjunction with the weighing silo, can precisely control the weight of the feed, ensuring formula accuracy. The temporary storage silo, combined with an electric gate valve, can control the feeding rhythm and prevent feed stagnation, ensuring continuous feeding. The pneumatic conveying pump uses a dense phase conveying method to drive the feed through the pipeline with high-pressure airflow for efficient transmission. Compared with traditional scraper conveyors, it eliminates complex mechanical parts such as elevators and towers, significantly reducing equipment investment and maintenance costs. At the same time, the fully enclosed pipeline conveying reduces dust pollution and improves the system's environmental friendliness. The connection between the silo and the mixer enables temporary storage and uniform mixing of feed. The entire system integrates feeding, weighing, conveying, storage, and mixing processes through intelligent control. It has advantages such as high automation, stable operation, low energy consumption, and long service life, effectively solving the problems of high investment, cumbersome control, frequent failures, and severe wear of traditional conveying methods, and greatly improving the efficiency and economy of ruminant feed preparation.

[0007] Preferably, the weighing bin is mounted on a support; a platform is mounted on the support; a through hole is provided in the middle of the platform; the weighing bin is mounted inside the through hole, and a weighing sensor is mounted on the platform in conjunction with the weighing bin; a butterfly valve is provided at the bottom outlet of the weighing bin; the butterfly valve is located above the temporary storage bin. The support frame ensures the stable installation of the weighing bin, and the through-hole design in the middle of the platform allows for embedded installation. Combined with the weighing sensors on the platform, this forms a precise weight monitoring system, enabling real-time and stable acquisition of feed weight data, providing reliable support for accurate control of feed formulation. The butterfly valve at the bottom outlet of the weighing bin is located above the temporary storage bin. It can be electrically controlled to quickly open or close the unloading channel, precisely controlling the timing and flow of feed release, avoiding the lag or leakage problems of traditional mechanical unloading. At the same time, the compact layout of the butterfly valve and the temporary storage bin shortens the feed transport path, reduces the risk of material stagnation, and improves the continuity and efficiency of the weighing and unloading process. The entire structure is compact and reasonable. Through the integrated design of mechanical support, weight monitoring, and unloading control, it ensures the accuracy of the weighing process and the convenience of the unloading operation, laying a stable foundation for subsequent feed conveying and mixing processes.

[0008] Preferably, the temporary storage compartment is mounted on the mounting plate; the mounting plate is fixedly mounted on the bracket; the outlet of the temporary storage compartment is equipped with a gate valve; the gate valve is connected to a pneumatic conveying pump. The temporary storage bin, fixed to the support frame by a mounting plate, achieves stable connection and efficient coordination with the weighing bin and pneumatic conveying pump. The fixed support of the mounting plate ensures the stable position of the temporary storage bin and precise alignment with the unloading port of the weighing bin above, ensuring smooth feed descent. The gate valve at the outlet of the temporary storage bin is directly connected to the pneumatic conveying pump, and the release rhythm of feed to the pump can be flexibly adjusted by switching it on and off. This facilitates the interruption of the feed flow when the pneumatic conveying system starts or stops, preventing pipe blockage or feed backflow and improving the controllability of the conveying process. In addition, the compact layout of this structure shortens the transmission distance between the temporary storage bin and the pneumatic conveying pump, reducing the residence time of feed in the transfer stage. At the same time, relying on the overall support of the frame, it reduces the impact of equipment vibration on unloading stability. The entire design, through mechanical fixing, valve control, and optimized spatial layout, ensures the continuity, accuracy, and reliability of the feed temporary storage and transfer process, providing key support for the stable operation of the pneumatic conveying system.

[0009] Preferably, the pneumatic conveying pump includes a tank; a valve is provided at the upper end of the tank; the valve is connected to a slide gate valve; an aeration plate is provided at the lower end of the tank; the upper and lower parts of the tank are connected to a compressed air source through pipelines; the lower end of the aeration plate is connected to a compressed air source through a pipeline; and a discharge port is provided on the lower side wall of the tank. The connection between the valve at the top of the tank and the slide gate valve allows for precise control of the feed feeding timing and flow rate, ensuring accurate material filling within the tank. Simultaneous connection of compressed air sources to both the top and bottom of the tank, combined with the design of the lower aeration disc, creates a uniform aeration flow field within the tank. This ensures that feed particles are fully suspended and mixed with the airflow, preventing powdery materials from settling and clumping, and improving material flowability at the initial stage of conveying. The aeration disc, separately connected to a compressed air source, can directionally enhance the aeration effect of the material at the bottom of the tank, preventing material stagnation in dead zones and ensuring complete feed delivery. The discharge port on the lower side wall of the tank, combined with airflow pressure and material gravity, forms a smooth discharge channel, reducing conveying resistance. The entire structure, through multi-source coordinated air supply, optimized flow field of the aeration disc, and precise valve control, achieves efficient fluidization, stable pushing, and continuous unloading of materials in dense-phase pneumatic conveying. This effectively solves the problems of material blockage and low conveying efficiency in traditional conveying methods, improving the system's adaptability to granular and powdery materials and enhancing conveying reliability.

[0010] Preferably, the compressed air source includes a buffer tank and an air compressor; the air compressor outlet is connected to the buffer tank; the buffer tank outlet is connected to the tank body and the vaporization disc via a pipeline. This provides a stable and reliable air source for the pneumatic conveying pump.

[0011] Preferably, a pusher plate is provided on the bottom surface of the temporary storage bin; one end of the pusher plate is fixedly mounted on a rotating shaft; the rotating shaft is rotatably mounted on the bottom surface of the temporary storage bin; the rotating shaft passes through the temporary storage bin and is connected to a motor. The linkage design of the pusher plate, rotating shaft, and motor in the temporary storage bin effectively solves the problems of feed retention and poor feeding: the pusher plate is fixed to the rotating shaft and rotated by the motor, which can form a continuous material pushing force on the bottom surface of the temporary storage bin. When the feed in the bin is insufficient or has high viscosity, the rotation of the pusher plate impeller gathers the residual feed at the bottom towards the outlet, avoiding dead corner retention caused by the accumulation of powdery or granular materials due to gravity.

[0012] Preferably, the pipeline connects two silos via a distributor.

[0013] Preferably, the distributor includes a housing; a circular ring is rotatably disposed within the housing; a straight pipe is fixedly disposed within the circular ring; a right-angle bend is fixedly disposed on one side of the straight pipe; three outlets are disposed on the outer peripheral wall of the housing; two of the outlets are coaxially disposed, and the center line of the remaining outlet is perpendicular to the center lines of the first two outlets; a hinge shaft is fixedly disposed on the outer wall of the straight pipe; the hinge shaft is rotatably disposed on the top surface of the housing; and a drive assembly is connected to the hinge shaft. By controlling the rotation of the hinge shaft through the drive assembly, the position of the circular ring can be quickly switched, so that the straight pipe or the right-angle bend is precisely aligned (coaxially or perpendicularly connected) with the three outlets on the outer periphery of the housing, thereby selecting the "straight-through" or "diversion" mode: when the straight pipe is aligned with the two coaxial outlets, continuous feeding of a single silo can be achieved; when the right-angle bend is aligned with the remaining outlet, the feed can be diverted to another silo, with a short switching response time.

[0014] Preferably, the drive assembly includes a connecting rod that is keyed to a hinge shaft; a hydraulic cylinder is connected to the end of the connecting rod away from the hinge shaft; the cylinder body of the hydraulic cylinder is hinged to the housing. The drive assembly adopts a mechanical linkage design of "connecting rod + hydraulic cylinder," providing stable and reliable power support for the path switching of the distributor.

[0015] Preferably, a cyclone separator is installed in the upper part of the silo; the cyclone separator is connected to an outlet. The design of installing a cyclone separator in the upper part of the silo significantly improves the efficiency of feed air separation and system stability: the cyclone separator can quickly separate the high-speed flowing feed particles from the air in the pneumatic conveying pipeline through centrifugal force. Due to the large centrifugal force, the particles are thrown against the inner wall of the silo and slide down the wall to the bottom of the silo, while the air is discharged through the central outlet of the separator.

[0016] The beneficial effects of this utility model are:

[0017] The screw conveyor, in conjunction with the weighing silo, can precisely control the weight of the feed, ensuring formula accuracy. The temporary storage silo, combined with an electric gate valve, can control the feeding rhythm and prevent feed stagnation, ensuring continuous feeding. The pneumatic conveying pump uses a dense phase conveying method to drive the feed through the pipeline with high-pressure airflow for efficient transmission. Compared with traditional scraper conveyors, it eliminates complex mechanical parts such as elevators and towers, significantly reducing equipment investment and maintenance costs. At the same time, the fully enclosed pipeline conveying reduces dust pollution and improves the system's environmental friendliness. The connection between the silo and the mixer enables temporary storage and uniform mixing of feed. The entire system integrates feeding, weighing, conveying, storage, and mixing processes through intelligent control. It has advantages such as high automation, stable operation, low energy consumption, and long service life, effectively solving the problems of high investment, cumbersome control, frequent failures, and severe wear of traditional conveying methods, and greatly improving the efficiency and economy of ruminant feed preparation.

[0026] The present invention will now be described and explained in detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, a dense-phase pneumatic conveying system for mixed concentrate feed includes a concentrate silo 1, a screw conveyor 2 connected to the lower outlet of the concentrate silo 1, a weighing silo 3 connected to the outlet of the screw conveyor 2, a temporary storage silo 4 connected to the outlet of the weighing silo 3, a pneumatic conveying pump 5 connected to the temporary storage silo 4, a silo 7 connected to the outlet of the pneumatic conveying pump 5 via a pipeline 6, and a mixer 8 connected to the outlet of the silo 7. The pipeline 6 connects to two silos 7 via a distributor 9.

[0029] The screw conveyor 2, in conjunction with the weighing bin 3, can precisely control the weight of the feed, ensuring the accuracy of the formula. The temporary storage bin 4, combined with the gate valve 15, can control the feeding rhythm and prevent feed stagnation, ensuring continuous feeding. The pneumatic conveying pump 5 uses a dense phase conveying method to drive the feed through the pipeline 6 with high-pressure airflow for efficient transmission. Compared with traditional scraper conveying, it eliminates complex mechanical parts such as elevators and towers, significantly reducing equipment investment and maintenance costs. At the same time, the fully enclosed pipeline conveying reduces dust pollution and improves the environmental friendliness of the system. The connection between the silo 7 and the mixer 8 realizes the temporary storage and uniform mixing of feed. The entire system integrates the entire process of feeding, weighing, conveying, storage and mixing through intelligent control. It has the advantages of high automation, stable operation, low energy consumption and long service life. It effectively solves the problems of high investment, cumbersome control, frequent failures and severe wear of traditional conveying methods, and greatly improves the efficiency and economy of ruminant feed preparation.

[0030] In the above configuration, the weighing chamber 3 is mounted on the support 10; a platform 11 is mounted on the support 10; a through hole is provided in the middle of the platform 11; the weighing chamber 3 is placed inside the through hole, and a weighing sensor 12 is mounted on the platform 11 in conjunction with the weighing chamber 3; a butterfly valve 13 is provided at the bottom outlet of the weighing chamber 3; the butterfly valve 13 is positioned above the temporary storage chamber 4. The temporary storage chamber 4 is mounted on the mounting plate 14; the mounting plate 14 is fixedly mounted on the support 10; a slide gate valve 15 is provided at the outlet of the temporary storage chamber 4; the slide gate valve 15 is connected to the pneumatic conveying pump 5.

[0031] The bracket 10 ensures the stable installation of the weighing bin 3. The through-hole design in the middle of the platform 11 allows the weighing bin 3 to be embedded and installed. Together with the weighing sensor 12 on the platform 11, a precise weight monitoring system is formed, which can obtain feed weight data in real time and stably, providing reliable support for the precision control of formula feeding. The butterfly valve 13 at the bottom outlet of the weighing bin 3 is located above the temporary storage bin 4. It can be quickly opened or closed by electric control, accurately controlling the timing and flow of feed release, avoiding the lag or leakage problems of traditional mechanical unloading. At the same time, the butterfly valve 13 and the temporary storage bin 4 are compactly arranged, shortening the feed transmission path, reducing the risk of material retention, and improving the continuity and efficiency of the weighing and unloading process. The entire structure is compact and reasonable. Through the integrated design of mechanical support, weight monitoring and unloading control, the accuracy of the weighing process and the convenience of unloading operation are ensured, laying a stable foundation for the subsequent feed conveying and mixing processes. The temporary storage bin 4 is fixed to the bracket 10 by the mounting plate 14, achieving stable connection and efficient coordination with the weighing bin 3 and the pneumatic conveying pump 5. The fixed support of the mounting plate 14 ensures that the temporary storage bin 4 is in a stable position and is precisely aligned with the discharge port of the weighing bin 3 above, ensuring the smooth flow of feed. The slide valve 15 at the outlet of the temporary storage bin 4 is directly connected to the pneumatic conveying pump 5, and the release rhythm of feed to the pump body can be flexibly adjusted by the switch control, which can cut off the material flow when the pneumatic conveying starts and stops, avoid pipeline blockage or feed backflow, and improve the controllability of the conveying process. In addition, the compact structure shortens the transmission distance between the temporary storage bin 4 and the pneumatic conveying pump 5, reduces the residence time of feed in the transfer link, and reduces the impact of equipment vibration on the unloading stability by relying on the overall support of the bracket 10. The whole design, through mechanical fixation, valve control and spatial layout optimization, ensures the continuity, accuracy and reliability of the feed temporary storage and transfer process, and provides key support for the stable operation of the pneumatic conveying system.

[0032] like Figure 3 and Figure 4 As shown, the pneumatic conveying pump 5 includes a tank 501; a valve 502 is installed at the upper end of the tank 501; the valve 502 is connected to a slide gate valve 15; an aeration plate 503 is installed at the lower end of the tank 501; the upper and lower parts of the tank 501 are connected to a compressed air source through pipelines; the lower end of the aeration plate 503 is connected to the compressed air source through pipelines; and a discharge port is provided on the lower side wall of the tank 501. The compressed air source includes a buffer tank 504 and an air compressor 505; the air outlet of the air compressor 505 is connected to the buffer tank 504; the air outlet of the buffer tank 504 is connected to the tank 501 and the aeration plate 503 through pipelines, which can provide a stable and reliable air source for the pneumatic conveying pump 5. A pusher plate 401 is installed on the bottom surface inside the temporary storage bin 4; one end of the pusher plate 401 is fixedly installed on a rotating shaft; the rotating shaft is rotatably installed on the bottom surface of the temporary storage bin 4; and the rotating shaft passes through the temporary storage bin 4 and is connected to a motor 402.

[0033] The connection between valve 502 at the upper end of tank 501 and slide gate valve 15 allows for precise control of feed feeding timing and flow rate, ensuring accurate material filling within tank 501. Compressed air sources are simultaneously connected to both the upper and lower parts of tank 501. Combined with the design of the lower aeration disc 503, this creates a uniform aeration flow field within the tank, ensuring feed particles are fully suspended and mixed with the airflow, preventing powdery materials from settling and clumping, and improving material flowability at the initial stage of conveying. The aeration disc 503, connected separately to a compressed air source, can directionally enhance the aeration effect of materials at the bottom of the tank, preventing… To prevent material stagnation in dead corners and ensure complete feed delivery within the tank, the discharge port on the lower side wall of tank 501, combined with air pressure and material gravity, forms a smooth discharge channel, reducing conveying resistance. The entire structure, through multi-source coordinated air supply, flow field optimization of the aeration plate 503, and precise control of valve 502, achieves efficient fluidization, stable pushing, and continuous unloading of materials in dense phase pneumatic conveying, effectively solving the problems of material blockage and low conveying efficiency in traditional conveying methods, and improving the system's adaptability to granular and powdery materials and its conveying reliability. The linkage design of the pusher plate 401, rotating shaft, and motor 402 in the temporary storage bin 4 effectively solves the problems of feed retention and poor feeding: the pusher plate 401 is fixed to the rotating shaft and driven to rotate by the motor 402, which can form a continuous material pushing force on the bottom surface of the temporary storage bin 4. When the feed in the bin is insufficient or has high viscosity, the impeller of the pusher plate 401 rotates to gather the residual feed at the bottom towards the outlet, avoiding dead corner retention caused by the accumulation of powder or granular material due to gravity.

[0034] like Figure 5 and Figure 6 As shown, the distributor 9 includes a housing 901; a circular ring 902 is rotatably disposed within the housing 901; a straight pipe 903 is fixedly disposed within the circular ring 902; a right-angle bend 904 is fixedly disposed on one side of the straight pipe 903; three outlets 905 are disposed on the outer peripheral wall of the housing 901; two of the outlets 905 are coaxially disposed, and the center line of the remaining outlet 905 is perpendicular to the center lines of the first two outlets 905; a hinge shaft 906 is fixedly disposed on the outer wall of the straight pipe 903; the hinge shaft 906 is rotatably disposed on the top surface of the housing 901; the hinge shaft 906 is connected to a drive assembly. The drive assembly includes a connecting rod 907 keyed to the hinge shaft 906; a hydraulic cylinder 908 is connected to the end of the connecting rod 907 away from the hinge shaft 906; the cylinder body of the hydraulic cylinder 908 is hinged to the housing 901. A cyclone separator 701 is disposed in the upper part of the silo 7; the cyclone separator 701 is connected to the outlet 905.

[0035] By controlling the rotation of the hinge shaft 906 through the drive assembly, the position of the ring 902 can be quickly switched, ensuring precise alignment and coaxial or perpendicular docking of the straight pipe 903 or right-angle bend 904 with the three outlets 905 on the outer periphery of the shell 901. This allows selection of either a "straight-through" or "diversion" mode: when the straight pipe 903 is aligned with two coaxial outlets 905, continuous feeding of a single silo 7 can be achieved; when the right-angle bend 904 is aligned with the remaining outlet 905, feed can be diverted to another silo 7, with a short switching response time. The drive assembly adopts a mechanical linkage design of "connecting rod 907 + hydraulic cylinder 908," providing stable and reliable power support for the path switching of the distributor 9. The design of a cyclone separator 701 installed in the upper part of the silo 7 significantly improves the efficiency of feed air separation and system stability: the cyclone separator 701 can quickly separate the feed particles flowing at high speed in the pneumatic conveying pipeline from the air through centrifugal force. Due to the large centrifugal force, the particles are thrown towards the inner wall of the silo 7 and slide down the wall to the bottom of the silo, while the air is discharged through the central outlet of the separator.
