[0001] This utility model relates to the field of hot blast stove technology, specifically a hot blast stove fuel feeding device. Background Technology

[0002] A hot blast stove is a type of thermodynamic machinery mainly used to heat blast air to the required temperature. It is widely used in industrial and civil fields. Hot blast stoves can generate high-temperature hot air by directly burning fuel for heating, drying, or baking materials. Hot blast stoves can burn a variety of fuels, including solid fuels, liquid fuels, and gaseous fuels. Hot blast stoves use solid fuels such as coal and biomass pellets for combustion, and the heat generated is transferred to the air through a heat exchanger, thereby heating the air and generating hot air.

[0003] Currently, most hot blast stoves still use manual methods to feed coal or biomass pellets. This method is time-consuming and labor-intensive, and the feeding amount cannot be fixed or well controlled according to the needs of the hot blast stove.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0011] Preferably, a reinforcing rod is provided between the supporting legs.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By extending the cylinder and using a pusher plate, the fuel is automatically pushed along the feeding chute into the connecting chute and then slides into the hot air furnace, thus completing the feeding process. This saves manpower and resources. Moreover, fuel only needs to be injected into the storage hopper, and the fuel is naturally discharged through the vibration of the vibrating motor. Then, the fuel can be evenly divided into equal portions by the distribution of the transfer chute, which makes it easy to control the feeding amount and ensure the working effect of the hot air furnace.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides a technical solution: including a support leg 1, a workbench 2 connected to the top of the support leg 1, a pad leg 3 connected to the top of the workbench 2, a storage hopper 4 connected to the top of the pad leg 3, a discharge hopper 5 connected to the bottom of the storage hopper 4, and a different height of the pad leg 3 due to the special shape of the discharge hopper 5, a material distribution plate 6 rotatably arranged inside the workbench 2, a drive motor 7 connected to the bottom of the workbench 2, the output end of the drive motor 7 passing through the workbench 2 and connected to the material distribution plate 6, a discharge pipe 8 connected to the bottom of the workbench 2, a feeding trough 9 rotatably arranged on one side of the feeding pipe 8, a cylinder 10 connected between the inner sides of the feeding trough 9, a push plate 11 connected to the output end of the cylinder 10, a guide rod 12 connected to one side of the push plate 11, a connecting rod 13 connected between the support legs 1, an electric push rod 14 rotatably arranged at both ends of the connecting rod 13, the other end of the electric push rod 14 rotatably connected to the discharge pipe 8, and a reinforcing rod 15 connected between the support legs 1;

[0020] Reference Figure 2 As shown, multiple sets of connecting bolts 41 are connected to one side of the inner wall of the storage hopper 4. A traction spring 42 is connected to the top of the connecting bolt 41, and a filter frame 43 is connected to the top of the traction spring 42. A vibration motor 44 is connected to the bottom of the filter frame 43. When fuel material is put into the storage hopper 4, the vibration motor 44 is started periodically to drive the filter frame 43 to move, thereby preventing material from piling up and clogging, and ensuring the feeding effect.

[0021] Reference Figure 3 As shown, the feeding trough 9 is connected to a connecting groove 91 at one end, and a round shaft is connected to the inner side of each groove. The round shaft is rotatably connected to the feeding pipe 8. The extension and retraction of the electric push rod 14 can drive the feeding trough 9 to rotate, thereby adjusting the angle position of the connecting groove 91 to facilitate feeding of hot air furnaces with different feeding port heights. The top of the distribution plate 6 has multiple sets of transfer grooves 61. The top and bottom of the worktable 2 are provided with through holes corresponding to the transfer grooves 61. The feeding pipe 8 and the feeding hopper 5 are connected to the corresponding through holes. The material enters the transfer groove 61 through the feeding hopper 5, and then moves to the top of the feeding pipe 8 as the distribution plate 6 rotates, and falls into the feeding trough 9 through the feeding pipe 8. Since the volume of the transfer grooves 61 is the same, the feeding amount can be controlled.

[0022] Reference Figure 2 As shown, a support frame is connected between the inner sides of the feeding trough 9. The cylinder 10 is fixedly installed on one side of the support frame. The guide rod 12 is slidably connected to the support frame. The extension of the cylinder 10 can push the material falling into the feeding trough 9 to the connecting groove 91 and slide it into the hot air furnace.

[0023] The implementation principle of this application is as follows: When this utility model is in use, the rotation of the feeding trough 9 is adjusted by the extension and retraction of the electric push rod 14 so that the connecting groove 91 is aligned with the feeding port of the hot air furnace. The vibration motor 44 is started, which drives the filter frame 43 to vibrate, shaking the fuel in the storage hopper 4 into the feeding hopper 5 and sliding it into the transfer trough 61. As the distribution plate 6 rotates, the fuel falls into the feeding trough 9 through the feeding pipe 8. Then the cylinder 10 pushes the push plate 11 to push the fuel into the connecting groove 91 and slide it into the hot air furnace.
