Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a multi-channel gas feeding device. Background Technology

[0002] For powdery or granular materials, pneumatic conveying pipes can be used for feeding. Pneumatic conveying systems are characterized by easy maintenance, labor saving, convenient installation, long conveying distance, and low failure rate, making them a highly efficient form of pneumatic conveying. Feeding shrimp in small sheds (multiple ponds per shed), factory-scale fish farming (multiple ponds per factory), and pig farming all require feeding multiple dispersed small sites. Using multiple feeders would be costly and labor-intensive; currently, there is no commercially available device that can provide uniform and controllable feeding to multiple sites using pneumatic conveying pipes.

[0003] Therefore, how to provide a multi-channel gas feeding device that can uniformly feed materials to multiple material-using sites through a single air conveying pipe and flexibly control the feeding is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, this utility model proposes a multi-channel gas feeding device, which aims to solve the technical problem that traditional gas feeding devices cannot conveniently and effectively feed materials evenly and controllably to multiple sites.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: This utility model provides a multi-channel gas feeding device, comprising: A feeding main pipe, one end of which is an air inlet; the outer peripheral wall of the feeding main pipe is provided with a plurality of discharge ports at intervals along the length direction; a feeding port is provided on the feeding main pipe between the air inlet and the discharge ports. An air supply device, wherein the air outlet of the air supply device is connected to the air inlet; Multiple branch feeding pipes, one end of each branch feeding pipe is connected to one of the multiple discharge ports, and the other end of each branch feeding pipe is a discharge connection port. The control component includes a controller and multiple electrically controlled valves; an electrically controlled valve is installed between any two adjacent discharge ports on the main feed pipe; electrically controlled valves are installed on multiple branch feed pipes; the controller is electrically connected to the multiple electrically controlled valves to control their opening and closing states.

[0006] In use, this multi-channel gas feeding device employs an air supply system to input airflow into the main feeding pipe, enabling pneumatic conveying of granular or powdery materials fed in through the inlet. The materials are then distributed and output through branch feeding pipes. Each branch feeding pipe's outlet can be connected to a feeding site or area (e.g., a fishpond, feed trough) via a duct, thus achieving uniform feeding to multiple material-using sites through a single pneumatic conveying pipe. A controller coordinates the opening and closing of multiple electrically controlled valves, allowing for flexible control of the branch feeding pipes' opening and closing status and feeding volume to meet specific feeding needs, achieving both uniform and on-demand feeding.

[0007] As a further improvement to the above technical solution, the gas supply equipment is a fan or an air pump.

[0008] The beneficial effect of the above technical solution is that the blower is used to pressurize the gas into the feeding pipe to provide sufficient airflow power for feeding.

[0009] As a further improvement to the above technical solution, the angle between the feeding direction of the multiple branch feeding pipes and the feeding direction of the main feeding pipe is less than 90 degrees.

[0010] The beneficial effects of the above technical solution are: by designing the inclination angle between the branch feeding pipe and the main feeding pipe, the pneumatic loss can be reduced, and the material accumulation at the discharge port can be avoided, thus affecting the material conveying effect.

[0011] As a further improvement to the above technical solution, the other port of the feeding main pipe is the discharge port two; an electrically controlled valve is provided on the feeding main pipe between the discharge port two and the discharge port one adjacent to the discharge port two.

[0012] The beneficial effects of the above technical solution are: designing the other port of the feeding main pipe as the discharge port two, by opening the corresponding electrically controlled valve, the material can be discharged through the discharge port two. At the same time, opening the discharge port two can realize the function of ventilation and cleaning of the feeding main pipe, thereby preventing pipe blockage.

[0013] As a further improvement to the above technical solution, the main feeding pipe is a straight pipe.

[0014] The beneficial effects of the above technical solution are: the main feeding pipe is designed as a straight pipe, which further improves the efficiency of pneumatic conveying and can effectively prevent blockage.

[0015] As a further improvement to the above technical solution, it also includes a connecting duct; one end of the connecting duct is connected to the air outlet of the air supply equipment, and the other end of the connecting duct is connected to the air inlet.

[0016] The beneficial effect of the above technical solution is that by connecting the air supply equipment through the air duct, it is possible to flexibly arrange the air supply equipment and the feeding main pipe.

[0017] As a further improvement to the above technical solution, the connecting duct is a flexible hose.

[0018] The beneficial effect of the above technical solution is that designing the connecting duct as a flexible hose makes it easy to bend and arrange.

[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a multi-channel gas feeding device, which has the following advantages and beneficial effects.

[0020] This invention enables uniform material feeding to multiple material-using sites through a single pneumatic conveying pipe, and allows for flexible material feeding control, thereby achieving independent control of material feeding at each material-using site. By connecting multiple relatively inclined branch material feeding pipes through a straight main feeding pipe, more uniform material feeding can be achieved. Attached Figure Description

[0031] One end of the feeding main pipe 1 is an air inlet 11; the outer peripheral wall of the feeding main pipe 1 is provided with multiple discharge ports 12 at intervals along the length direction; a feeding port 13 is provided on the feeding main pipe 1 between the air inlet 11 and the discharge ports 12.
