Description

Technical Field

[0001] The utility model relates to the technical field of fuel filling equipment, in particular to a solid fuel filling proportioning device. Background Art

[0002] A fuel dispenser is a device used to add fuel to a device, such as a car, airplane, rocket, etc. The form of the fuel dispenser will vary depending on the type of fuel being added and the device being added.

[0003] The existing fuel fillers are usually filled manually, which leads to a large workload for the staff. In order to reduce the workload of the staff, the existing fuel filling devices will be improved. For example, the existing publication number CN213453710U discloses a fuel filling device for a biomass fuel boiler, which is provided with an inclined surface at the bottom of the storage box, which is used in conjunction with a liftable conical stopper. The biomass fuel particles in the storage box are dropped into the feeding barrel by the lifting of the conical stopper, and finally the feeding screw is driven by a second motor to transport the biomass fuel particles in the feeding barrel to the boiler. In this way, biomass particle fuel can be automatically added to the boiler, reducing the workload of the staff.

[0004] However, when implementing the above-mentioned fuel filling device for the biomass fuel boiler, at least the following problem was found: when the above-mentioned device is transmitting biomass fuel particles, due to the inclined surface of the bottom of the storage box, the biomass fuel particles will inevitably contact the conical plug and remain on the top of the conical plug. In addition, when the biomass fuel particles are transmitted by the feeding screw, some biomass fuel particles will be missed in the feeding barrel during the rotation process, resulting in unnecessary fuel loss during transportation.

[0005] In order to solve the above problems, we proposed a solid fuel filling and proportioning device. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example: See Figures 1 to 4 According to an embodiment of the utility model, a technical solution is provided: a solid fuel filling and proportioning device, comprising a filling slot 1, a feeding slot 2 is fixedly connected to the top of one end of the filling slot 1, an opening is provided on a side of the feeding slot 2 close to the filling slot 1, a discharge slot 3 is provided on the end of the filling slot 1 away from the feeding slot 2, a first conveyor belt 4 is fixedly installed in the filling slot 1, a plurality of distribution plates 5 are distributed at intervals on the first conveyor belt 4, the distribution plates 5 are spoon-shaped and fixedly connected to the first conveyor belt 4, an arc-shaped structure is formed at one end of the filling slot 1 close to the feeding slot 2, a feeding plate 6 is slidably connected to a side of the feeding slot 2 with an opening, and a side of the filling slot 1 close to the bottom of the feeding slot 2 is an inclined surface.

[0027] The proportioning device adopts the above structure, firstly, solid fuel such as coal blocks is stored in the feeding trough 2, and the feeding plate 6 will block the opening of the feeding trough 2 in the initial state to prevent the fuel stored in the feeding trough 2 from sliding into the filling trough 1. After the fuel is added, the feeding plate 6 can be slid to open the opening of the feeding trough 2, and the fuel will slide along the inclined surface at the bottom of the feeding trough 2 into the filling trough 1, and then the first conveyor belt 4 is started. When the first conveyor belt 4 rotates, it will drive the distribution plate 5 to rotate together. The distribution plate 5 with a spoon-shaped structure cooperates with the arc structure of the filling trough 1, and can continuously dig out the fuel in the filling trough 1 and transport it to the discharge trough 3, and deliver the fuel to the target through the discharge trough 3. The utility model is simple and convenient to use, and can continuously clean the inside of the filling trough 1 through the distribution plate 5 during transportation, thereby reducing the occurrence of fuel residue during transportation.

[0028] See also Figures 1 to 3 In this embodiment, a frame 7 is provided at the bottom of the filling tank 1, one side of the filling tank 1 is rotatably connected to the frame 7, and vertical plates 8 are fixedly connected to the two sides of the top of the frame 7. A slider 9 is provided between the two vertical plates 8, and a slide bar 10 is rotatably connected between the slider 9 and the bottom of the filling tank 1. A screw 11 is also rotatably connected between the two vertical plates 8. The slider 9 is threadedly connected to the screw 11. When it is necessary to add fuel to a higher target, the screw 11 can be rotated to drive the slider 9 to move. When the slider 9 moves, it will drive the slide bar 10 to move and support the filling tank 1. With the help of the slide bar 10, the elevation angle of the filling tank 1 can be adjusted to achieve the goal of filling fuel at a higher place.

[0029] See also Figure 3 In this embodiment, a first motor 12 is fixedly connected to the outer side of the vertical plate 8, and the output end of the motor is fixedly connected to one end of the screw 11. Compared with other driving methods, the selection of the first motor 12 has the advantages of easy implementation, low cost, and convenient use.

[0030] See also Figure 4 In this embodiment, a rack 13 is fixedly connected to one side of the feeding plate 6, and a gear 14 meshing with the rack 13 is rotatably connected to one side of the feeding trough 2. A rotating shaft 15 is fixedly connected to the center of the gear 14. A second motor 16 is also provided on one side of the feeding trough 2. The output end of the second motor 16 is fixedly connected to the rotating shaft 15. When it is necessary to open the opening of the feeding trough 2, the motor can be started to drive the gear 14 to rotate. When the gear 14 rotates, it will drive the rack 13 meshing with it to rise or fall, thereby adjusting the rise or fall of the feeding plate 6 and controlling the opening and closing of the feeding trough 2. In addition, the rising degree of the feeding plate 6 can be adjusted by the rack 13, so as to adjust the size of the opening of the feeding trough 2. In this way, the feeding speed of the fuel in the feeding trough 2 can be controlled.

[0031] See also Figures 1 to 3In this embodiment, the top openings of the feeding trough 2 and the discharging trough 3 are both inclined, and the feeding trough 2 and the discharging trough 3 are both fixedly connected to the filling trough 1. By setting the top openings of the feeding trough 2 and the discharging trough 3 as inclined surfaces, when adding fuel to the feeding trough 2, the inclined opening can make it more convenient to add fuel, and the inclined surface of the top opening of the discharging trough 3 can make it more convenient to add fuel to the filling trough 1.

[0032] See also Figure 4 In this embodiment, a second conveyor belt 17 is fixedly installed on the inclined surface of the filling trough 1 near the bottom of the feeding trough 2. After the filling trough 1 adjusts its elevation angle, the feeding trough 2 will also be inclined, so the efficiency of fuel delivery into the filling trough 1 may be reduced. The second conveyor belt 17 is arranged here. Through the rotation of the second conveyor belt 17, the fuel in the feeding trough 2 can be quickly transported to the filling trough 1, so as to increase the fuel delivery speed when the feeding trough 2 is inclined.

[0033] Working principle: When using the above-mentioned proportioning device, firstly store solid fuel such as coal blocks in the feeding trough 2. The feeding plate 6 will initially block the opening of the feeding trough 2 to prevent the fuel stored in the feeding trough 2 from sliding into the filling trough 1. After the fuel is added, the first motor 12 can be started to drive the screw 11 to rotate, drive the slider 9 to move and adjust the elevation angle of the filling trough 1. After the adjustment is completed, the second motor 16 can be started to drive the gear 14 to rotate, and the feeding plate 6 is driven to rise through the rotation of the gear 14. When the feeding plate 6 rises, the opening of the feeding trough 2 is opened, and the fuel will slide along the inclined surface at the bottom of the feeding trough 2 into the filling trough 1. Then the first conveyor belt 4 is started, and the first conveyor belt 4 When rotating, the distribution plate 5 will be driven to rotate together. The distribution plate 5 with a spoon-shaped structure cooperates with the arc structure of the filling groove 1, and can continuously dig out the fuel in the filling groove 1 and transport it to the discharge groove 3, and deliver the fuel to the target through the discharge groove 3. When the inclination angle of the feeding groove 2 is large, resulting in low fuel delivery efficiency, the second conveyor belt 17 can be started. When the second conveyor belt 17 rotates, it will continuously drive the fuel in the feeding groove 2 to move and transport it to the filling groove 1, thereby improving the fuel delivery efficiency. The utility model is simple and convenient to use, and can continuously clean the inside of the filling groove 1 through the distribution plate 5 during transportation, thereby reducing the occurrence of fuel residue during transportation.
