Description

Technical Field

[0001] This utility model relates to the field of material conveying and feeding technology, specifically an automatic material conveying and feeding device for a heating combustion furnace. Background Technology

[0002] A combustion furnace is an energy converter that uses the heat energy released from fuel combustion or other heat energy to heat the working fluid, water or other fluids, to certain parameters.

[0003] The utility model patent with publication number CN211894797U discloses an automatic conveying and feeding device for a heating combustion furnace. It solves the problems of existing combustion furnaces typically lacking automated feeding mechanisms, requiring significant labor, resulting in high labor intensity and unreliable combustion conditions. The device uses a pusher cylinder to open and close a baffle plate at the outlet of the hopper, feeding and stopping the fuel in the hopper. One end of the conveyor belt has a receiving port located at the bottom of the hopper's outlet for easy receiving. The other end of the conveyor belt is connected to the furnace's inlet via a downwardly angled guide pipe for convenient feeding. While the structure is simple, in actual use, after the baffle plate opens, a large amount of material quickly falls to the top of the conveyor belt without proper material distribution, easily leading to spillage and poor feeding efficiency. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide an automatic conveying and feeding device for a heating combustion furnace, which has the advantage of good feeding effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic conveying and feeding device for a heating combustion furnace, comprising a storage hopper, a guide pipe connected to the bottom of the storage hopper, a conveyor arranged on the right side of the storage hopper, a combustion furnace body arranged on the right side of the conveyor, a feed pipe connected to the left side of the combustion furnace body, the feed inlet of the feed pipe being located below the discharge end of the conveyor, a support frame fixedly connected to the left side of the conveyor, the support frame being fixedly connected to the guide pipe, a baffle slidably connected inside the guide pipe, support rods fixedly connected to the front and rear sides of the left side of the baffle, a rectangular frame fixedly connected to the left side of the support rod, a motor fixedly connected to the left side of the support frame via a bracket, a turntable fixedly connected to the output end of the motor, a round rod rotatably connected to the top of the turntable, the round rod fitting against the inner wall of the rectangular frame, the discharge outlet of the guide pipe being located above the feed end of the conveyor, and a material equalization component fixedly connected to the surface of the conveyor.

[0006] In a preferred embodiment of this invention, the material equalization assembly includes a fixed frame fixedly connected to the surface of the conveyor. Limiting rods are slidably connected to the front and rear sides inside the fixed frame. A material equalization frame is fixedly connected to the bottom of the limiting rods. A threaded rod is rotatably connected to the top of the material equalization frame. The threaded rod is threadedly connected to the fixed frame. The top of the threaded rod extends above the fixed frame and is fixedly connected to a rotating handle.

[0007] As a preferred embodiment of this invention, baffle plates are fixedly connected to both the front and back sides of the top of the conveyor.

[0008] As a preferred embodiment of this utility model, the surface of the barrier plate is rotatably connected to a material distribution roller, and the number of material distribution rollers is several. Each material distribution roller is a cylinder with a small diameter at both ends and a large diameter in the middle.

[0009] As a preferred embodiment of this utility model, the material distribution rack is internally fixedly connected to a bearing, the outer ring of the bearing is fixedly connected to the material distribution rack, the inner ring of the bearing is fixedly connected to the threaded rod, and a sealing shaft cover is provided inside the bearing.

[0010] As a preferred embodiment of the present invention, a reinforcing frame is fixedly connected to the surface of the conveyor, the end of the reinforcing frame away from the conveyor is fixedly connected to a support frame, a connecting frame is fixedly connected to the top of the fixed frame, and the end of the connecting frame away from the fixed frame is fixedly connected to a guide pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model allows the operator to start a motor to rotate a turntable, which in turn rotates a round rod around the turntable's axis, causing a rectangular frame to move back and forth, which in turn causes the support rod and baffle to move back and forth. The material in the storage hopper falls onto the surface of the conveyor through a guide pipe. The left and right reciprocating movement of the baffle, for example, when the baffle moves to the right, can reduce the discharge speed of the guide pipe, preventing the material from falling onto the surface of the conveyor too quickly and causing spillage. The material leveling component can flatten the material falling onto the surface of the conveyor, further preventing spillage. This device has the advantage of good material feeding effect.

[0013] 2. With the addition of a material leveling component, the operator can rotate the threaded rod, which in turn moves the threaded rod up or down, thereby moving the material leveling rack up or down. This allows for adjustment of the distance between the material leveling rack and the conveyor. The material leveling rack can then level the material on the surface of the conveyor, thus preventing the material from spilling off the conveyor. Attached Figure Description

[0019] 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.

[0020] like Figures 1 to 4 As shown, an automatic conveying and feeding device for a heating combustion furnace includes a storage hopper 1, a guide pipe 2 connected to the bottom of the storage hopper 1, a conveyor 3 arranged on the right side of the storage hopper 1, a combustion furnace body 4 arranged on the right side of the conveyor 3, a feed pipe 5 connected to the left side of the combustion furnace body 4, the feed inlet of the feed pipe 5 being located below the discharge end of the conveyor 3, a support frame 9 fixedly connected to the left side of the conveyor 3, the support frame 9 being fixedly connected to the guide pipe 2, a baffle 6 slidably connected inside the guide pipe 2, support rods 7 fixedly connected to the front and rear sides of the left side of the baffle 6, a rectangular frame 8 fixedly connected to the left side of the support rod 7, a motor 10 fixedly connected to the left side of the support frame 9 via a bracket, a turntable 11 fixedly connected to the output end of the motor 10, a round rod 12 rotatably connected to the top of the turntable 11, the round rod 12 fitting against the inner wall of the rectangular frame 8, the discharge outlet of the guide pipe 2 being located above the feed end of the conveyor 3, and a material equalization component 13 fixedly connected to the surface of the conveyor 3.

[0021] refer to Figure 1 and Figure 2The material equalization assembly 13 includes a fixed frame 14 fixedly connected to the surface of the conveyor 3. The front and rear sides of the fixed frame 14 are slidably connected to limit rods 15. The bottom of the limit rods 15 is fixedly connected to a material equalization frame 16. The top of the material equalization frame 16 is rotatably connected to a threaded rod 17. The threaded rod 17 is threadedly connected to the fixed frame 14. The top of the threaded rod 17 extends to the top of the fixed frame 14 and is fixedly connected to a handle.

[0022] As a technical optimization of this utility model, by setting the material distribution component 13, the operator can rotate the threaded rod 17, thereby driving the threaded rod 17 to move up or down, thereby driving the material distribution frame 16 to move up or down, thereby adjusting the distance between the material distribution frame 16 and the conveyor 3. The material distribution frame 16 can flatten the material on the surface of the conveyor 3, thereby preventing the material from spilling from the conveyor 3.

[0023] refer to Figure 1 Baffle plates 20 are fixedly connected to both the front and back of the top of the conveyor 3.

[0024] As a technical optimization of this utility model, by setting the baffle plate 20, the material on the surface of the conveyor 3 can be blocked and limited, thereby avoiding the phenomenon of material spillage.

[0025] refer to Figure 1 The surface of the barrier plate 20 is rotatably connected to a material distribution roller 21. There are several material distribution rollers 21, and each material distribution roller 21 is a cylinder with a small diameter at both ends and a large diameter in the middle.

[0026] As a technical optimization of this utility model, by setting the material distribution roller 21, the material distribution roller 21 is a column with a large diameter in the middle and a small diameter at both ends, and the diameter decreases from the middle to both ends. When the material touches the material distribution roller 21, the material distribution roller 21 can flatten the material at both ends, thereby preventing the material from spilling from the conveyor 3.

[0027] refer to Figure 1 and Figure 2 The material distribution frame 16 is internally fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to the material distribution frame 16, while the inner ring of the bearing is fixedly connected to the threaded rod 17. A sealing shaft cover is provided inside the bearing.

[0028] As a technical optimization of this utility model, the friction between the material equalizer 16 and the threaded rod 17 can be reduced by setting the bearing, thereby facilitating the rotation of the threaded rod 17.

[0029] refer to Figure 1A reinforcing frame 18 is fixedly connected to the surface of the conveyor 3. The end of the reinforcing frame 18 away from the conveyor 3 is fixedly connected to the support frame 9. A connecting frame 19 is fixedly connected to the top of the fixed frame 14. The end of the connecting frame 19 away from the fixed frame 14 is fixedly connected to the guide pipe 2.

[0030] As a technical optimization of this utility model, the stability of the guide pipe 2, support frame 9 and storage hopper 1 can be improved by setting the reinforcing frame 18 and connecting frame 19.

[0031] The working principle and usage process of this utility model are as follows: When in use, the operator can start the motor 10 to rotate and drive the turntable 11 to rotate, which in turn drives the round rod 12 to rotate around the axis of the turntable 11, which in turn drives the rectangular frame 8 to move back and forth, which in turn drives the support rod 7 and the baffle 6 to move back and forth. The material in the storage hopper 1 falls into the surface of the conveyor 3 through the guide pipe 2. By moving the baffle 6 back and forth, for example, when the baffle 6 moves to the right, the feeding speed of the guide pipe 2 can be reduced, which can prevent the material from falling onto the surface of the conveyor 3 quickly in a short time and causing the material to spill. Through the setting of the material leveling component 13, the material falling onto the surface of the conveyor 3 can be leveled, which can further prevent the material from spilling and improve the feeding effect. The conveyor 3 transports the material into the feed pipe 5 and then into the combustion furnace body 4.

[0032] The aforementioned conveyor 3, combustion furnace body 4, and feed pipe 5 are all similar in principle to the conveyor belt, combustion furnace, and feed pipe mentioned in the utility model patent (publication number: CN211894797U) "An Automatic Conveying and Feeding Device for Heating Combustion Furnace", and achieve the same effect. This application will not elaborate further.
