Description

Technical Field

[0001] The utility model relates to an unpowered intensive tobacco curing barn intelligent distribution and feeding system, belonging to the technical field of tobacco curing equipment. Background Art

[0002] Flue-curing barns are an essential piece of infrastructure in flue-cured tobacco production. After being cured and tempered in the flue-cured barn, the tobacco develops its unique color, aroma, flavor, and shape, becoming a high-quality raw material that meets the needs of the tobacco industry. Therefore, the sophistication of the flue-curing barn directly affects the quality of the finished flue-cured tobacco.

[0003] During traditional tobacco curing, burners burn fuel to provide heat within the flue-curing barn, serving as the heat source for the tobacco leaves. However, the tobacco curing cycle is long, typically lasting 7-8 days. This requires a continuous fuel supply to maintain the required heat. Curing facilities are large, with some boasting over 100 flue-curing barns. The actual burner hopper capacity is small, requiring frequent manual loading. Curing in each flue-curing barn does not start and end at the same time, and inconsistent curing times result in inconsistent fuel consumption. A biomass bag weighs approximately 25 kg, and four bags fill a bucket. A bucket of 25 x 4 = 100 kg. A flue-curing barn consumes approximately 50 bags per curing cycle, or 50 x 25 = 1250 kg. This requires at least 12.5 manual loadings (1250 / 100 = 1250 / 100 = 12.5 times). All of the above results in a huge workload for manual loading, and the staff need to pay attention to the supply of fuel at all times, and replenish the fuel in time when the fuel is insufficient to ensure the normal baking work. The staff are often required to replenish the fuel at night, which increases manpower and material resources. If the fuel is insufficient, it will have a huge impact on the baking of tobacco leaves, seriously endangering the quality of the tobacco leaves after baking and causing property losses.

[0004] Patent document CN 220229247 U discloses a biomass fuel feeding mechanism for a dense baking room, comprising a storage box, an igniter disposed below the storage box, and a second fixed plate. The top outer wall of the second fixed plate is fixedly connected to a first motor, the output end of the first motor is fixedly connected to a first auger, the top outer wall of the second fixed plate is fixedly connected to a reinforcing column, one end of the reinforcing column is fixedly connected to the first fixed plate, and the circumferential inner wall of the first fixed plate is fixedly connected to a storage barrel. This device can automatically replenish biomass fuel without the need for manual addition by staff, reducing the staff's filling intensity. However, when the burner is working, it requires the use of multiple motors to complete the feeding, which has problems such as high cost, excessive weight, inability to transmit over long distances, and difficulty in maintenance.

[0030] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1-4 As shown, the first embodiment of the present invention provides a non-powered intensive baking room intelligent distribution and feeding system, comprising:

[0032] The storage device 1 is connected to the biomass fuel storage device through the feeding mechanism 2;

[0033] A feed pipe group 3, one end of which is connected to the storage device 1, and the other end of which is arranged obliquely downward in the direction of the intensive baking room 4 away from the storage device 1, and the feed pipe group 3 is provided with a plurality of feeding ports connected to the burner 5 of the intensive baking room;

[0034] The elastic connecting frame 13 is arranged at intervals between multiple dense baking rooms, and the elastic connecting frame 13 gradually lengthens in the direction of the dense baking room 4 away from the storage device 1, so that the feed pipe group 3 is connected to the concentrated baking room 4 through the elastic connecting frame 13.

[0035] The feed pipe group 3 includes a main feed pipe 301, the feed end of which is connected to the storage device 1, and a plurality of feed branch pipes 302 are provided at the discharge end. The arrangement of the feed branch pipes 302 corresponds to the plurality of row curing barn groups. The feed branch pipes 302 are provided with a plurality of feed ports connected to the burners 5 of the intensive curing barns. The main feed pipe 301 and the feed branch pipes 302 are arranged to be inclined downwardly in the direction of the intensive curing barns 4. Preferably, the inclination angle of the main feed pipe 301 and the feed branch pipes 302 can be 10-30 degrees.

[0036] The elastic connecting frame 13 includes a sleeve 1301 adapted to the outer diameter of the feed branch pipe 302. The sleeve 1301 is connected to the top of the densely packed curing rooms 4 via a spring connecting rod 1302. Multiple elastic connecting frames 13 are spaced along each row of curing rooms. The spring connecting rods 1302 gradually lengthen from the material storage device 1 toward the curing room cluster, allowing the main feed pipe 301 and the feed branch pipe 302 to be installed downwardly and tilted toward the densely packed curing rooms 4. Because the elastic connecting frame 13 has a certain elastic expansion margin, it facilitates the downwardly and tilted arrangement of the main feed pipe 301 and the feed branch pipe 302 along the densely packed curing rooms 4, and is highly convenient to install.

[0037] The main feed pipe 301 and branch feed pipe 302 are formed by splicing together several pipes. The pipe sleeve 1301 is a flange structure or a flexible hose. The joint between the main feed pipe 301 and branch feed pipe 302 can be rigidly connected by a flange structure, or flexibly connected by a flexible hose. A flexible connection is preferably used, as it not only improves connection reliability but also facilitates pipe arrangement.

[0038] Furthermore, a guide plate 14 is provided in the feed branch pipe, near the lower end of the feed port. The guide plate 14 separates the feed port of the feed branch pipe from the logistics channel. When the material flows in the feed branch pipe, part of it enters the baking room burner 5 from the feed port, and the other part flows into the next feed port through the logistics channel. The guide plate 14 guides the flow, making fuel distribution more convenient.

[0039] The storage device 1 includes a support truss 101, with a storage bin 102 located on top of the support truss 101. The inlet of the storage bin 102 is connected to the feeding mechanism 2, and the outlet is connected to the main feed pipe 301 of the feed pipe group. The height of the support truss 101 is slightly higher than the intensive curing room 4, which makes it easier to arrange the main feed pipe 301 and the feed branch pipe 302 obliquely downward along the direction of the intensive curing room 4.

[0040] The feeding mechanism 2 can be a feeding belt, a spiral lifting and feeding device, etc. Through the feeding mechanism 2 , the biomass fuel in the biomass fuel storage device can be lifted and added into the storage bin 102 .

[0041] During use, the feeding mechanism 2 adds the fuel in the biomass fuel storage equipment into the storage device 1. Since the feed main pipe 301 and the feed branch pipe 302 are arranged to be inclined downward along the direction of the dense baking room 4, the fuel in the storage device 1 can be transmitted to the burner 5 of the dense baking room under the action of gravity. This structure can reduce the problems of high cost, excessive weight, inability to transmit over long distances, and difficult maintenance caused by the complex design structure of the equipment.

[0042] The system also includes an intelligent distribution and feeding system, which consists of a main control valve 6 installed at the inlet end of each feed branch pipe 301 and a sub-control valve 7 installed at each feed inlet on the feed branch pipe. The main control valve 6 and the sub-control valve 7 are connected to the controller 8 of the intensive curing room. The main control valve 6 is used to control the flow between the main feed pipe 301 and each feed branch pipe 302, while the sub-control valve 7 is used to control the amount of fuel released into the burner 5 in each curing room. The main control valve 6 and the sub-control valve 7 can be butterfly valves.

[0043] Example 2

[0044] Based on Example 1, the intelligent distribution and feeding system further includes a first height limiter 10, located on the storage hopper of each barn burner 5. This first height limiter 10 is connected to the controller 8 and measures the material accumulation depth. When the accumulation depth falls below a lower limit, it provides a signal to the burner that refueling is required. If no refueling is required in any barn, the entire intelligent distribution and feeding system is inactive. This first height limiter 10 can be an infrared sensor or a material level meter using ultrasonic, radar, capacitance, or nuclear radiation.

[0045] Example 3

[0046] Based on Examples 1 and 2, the intelligent distribution feeding system further includes a pressure sensor 9 provided at the bottom of the storage bin 102. The pressure sensor 9 is connected to the controller 8 of the intensive baking room and is used to measure the fuel load in the storage bin.

[0047] A second height limiter 12 is also provided in the storage bin 102. This second height limiter 12 can be a camera or a material level meter using ultrasonic, radar, capacitance, or nuclear radiation. The second height limiter 12 is connected to an alarm 11 via the controller 8 of the intensive baking room. The alarm 11 can be a three-color buzzer that provides upper and lower limit warnings. When the fuel level in the storage bin 102 is below the preset lower limit, the three-color buzzer sounds and illuminates red. When the fuel level in the storage bin 102 is above the preset upper limit, the three-color buzzer sounds and illuminates yellow. When the fuel level in the storage bin 102 is between the upper and lower limits, the three-color buzzer only illuminates green and does not sound. This serves to remind staff to replenish materials in a timely manner.

[0048] The above description is only a preferred embodiment of the present invention and does not constitute any form of confidentiality restriction on the present invention. Any simple modification, equivalent change and modification of the above embodiment made based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
