Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a material conveying device for a cogeneration combustion boiler. Background Technology

[0002] In the field of combined heat and power (CHP), the combustion boiler is a core piece of equipment, and its material conveying efficiency directly affects energy utilization efficiency and production benefits. Bucket conveyors, with their continuous and efficient conveying characteristics, have become one of the commonly used equipment for material transfer in this industry, widely used in the conveying of fuels such as coal and biomass. Existing bucket conveyors mostly use a fixed structure design for their hoppers. This fixed shape of the hoppers cannot flexibly change its shape according to actual production needs. When it is necessary to adjust the material conveying volume, the fixed structure of the hoppers cannot meet the requirements for precise control of the material quantity, resulting in excessive or insufficient material conveying. This not only causes energy waste and increased equipment operating pressure but also affects the stable combustion and production output of the boiler. Therefore, this utility model proposes a material conveying device for a CHP combustion boiler. Utility Model Content

[0003] The purpose of this invention is to address the problem that in the background technology, most hoppers adopt a fixed structure design. This fixed shape of the hopper cannot flexibly change its shape according to actual production needs. When it is necessary to adjust the material conveying volume, the fixed structure of the hopper cannot meet the requirements of precise control of the material volume, resulting in too much or too little material being conveyed. This not only causes energy waste and increased equipment operating pressure, but also affects the stable combustion and production capacity output of the boiler. The invention proposes a material conveying device for cogeneration combustion boilers.

[0004] The technical solution of this utility model is as follows: A material conveying device for a cogeneration combustion boiler includes: a support frame, a set of transmission rollers rotatably arranged between the support frames, and a transmission belt arranged between the transmission rollers; a motor fixedly arranged on one side of the support frame, the output end of the motor being connected to one end of the transmission rollers through a steering gear; and multiple connecting plates fixedly arranged on the outer wall of the transmission belt, with a hopper assembly for material conveying fixedly arranged on one side of each connecting plate.

[0005] Optionally, the hopper assembly includes a first hopper fixedly disposed on one side of the connecting plate, a guide plate fixedly disposed on the inner bottom surface of the first hopper, a guide groove formed on the upper surface of the guide plate, a guide strip slidably disposed inside the guide groove, and a second hopper fixedly disposed on one side of the guide strip.

[0006] Optionally, the hopper assembly further includes a support frame fixedly disposed on the bottom surface of the first hopper, a bidirectional threaded rod rotatably disposed between the support frames, a set of linkage rods threaded onto the outer wall of the bidirectional threaded rods, one end of the linkage rods passing through the support frame and fixedly connected to the second hopper.

[0007] Optionally, support rods are fixedly arranged on both sides of the support frame, and feet are fixedly arranged at the lower ends of the support rods.

[0008] Optionally, a feed hopper is fixedly arranged on one side of the support frame.

[0009] Optionally, the linkage rod is arranged in a "C" - shaped structure.

[0010] In summary, the present application includes at least the following beneficial technical effects:

[0011] Through the structural design of the guide plate, guide groove, guide strip, first hopper, and second hopper in the hopper assembly of the present utility model, the sliding of the second hopper in the first hopper is realized. The volume shape of the hopper can be flexibly changed according to actual production requirements, so as to accurately control the material conveying amount, avoid the situation of too much or too little conveyed material, reduce energy waste, lower the operating pressure of the equipment, and ensure the stable combustion of the boiler and the output of production capacity.

[0012] Furthermore, through the structure of the support frame, bidirectional threaded rod, and linkage rod in the hopper assembly of the present utility model, rotating the bidirectional threaded rod can drive a group of linkage rods to move synchronously, which can conveniently adjust the position of the second hopper in the first hopper, quickly change the accommodation space of the hopper, better meet the requirements of different material conveying amounts, and improve the flexibility and accuracy of material conveying.

[0025] Example

[0026] like Figure 1 As shown, the material conveying device for a cogeneration combustion boiler proposed in this utility model includes: a support 1, two supports 1 are provided and are arranged symmetrically, a support rod 8 is fixedly provided on both sides of the support 1, and a support leg 9 is fixedly provided at the lower end of the support rod 8 to provide stable support for the support 1, a guide hopper 10 is fixedly provided on one side of the support 1, the guide hopper 10 is inclined to guide and convey materials, and facilitate the material to be transferred into the combustion boiler, a set of transmission rollers 2 are rotatably arranged between the supports 1 through a bearing seat, and a transmission belt 3 is arranged between the transmission rollers 2 to enable the transmission rollers 2 to drive the transmission belt 3 to rotate stably.

[0027] Furthermore, a motor 4 is fixedly arranged on one side of the support 1. The output end of the motor 4 is connected to one end of the transmission roller 2 through a steering gear 5. The motor 4 can change the driving direction through the steering gear 5, so that the motor 4 drives the transmission roller 2 to rotate, and the conveyor belt 3 conveys the material.

[0028] As Figure 2 and Figure 3 shown, a plurality of connecting plates 6 are fixedly arranged on the outer wall of the conveyor belt 3. The connecting plates 6 are made of silica gel and have excellent high and low temperature resistance. The working temperature is generally between -60°C and 260°C, ensuring that it can be used in the high temperature environment of the boiler workshop. It is convenient for the conveyor belt 3 to drive the connecting plate 6 to bend at the transmission roller 2. A hopper assembly 7 for conveying materials is fixedly arranged on one side of the connecting plate 6. The hopper assembly 7 includes a first hopper 71 fixedly arranged on one side of the connecting plate 6, and one side of the first hopper 71 is inclined. A guide plate 72 is fixedly arranged on the inner bottom surface of the first hopper 71. A guide groove 73 is formed on the upper surface of the guide plate 72, and the guide groove 73 is arranged in a "convex" shape. A guide bar 74 is slidably arranged in the guide groove 73, and the guide bar 74 is also arranged in a "convex" shape, which can make the guide bar 74 slide stably in the guide groove 73. A second hopper 75 is fixedly arranged on one side of the guide bar 74, and one side of the second hopper 75 is inclined.

[0029] Furthermore, the hopper assembly 7 further includes a support frame 76 fixedly arranged on the bottom surface of the first hopper 71. A bidirectional threaded rod 77 is rotatably arranged between the support frames 76 through bearings. The bidirectional threaded rod 77 is made of high-temperature stainless steel to avoid expansion in a high-temperature environment. The support frame 76 can be blocked by a linkage rod 78, so that the bidirectional threaded rod 77 is sealed inside the support frame 76 to avoid咬死 with the pulverized coal in contact with the bidirectional threaded rod 77. One end of the bidirectional threaded rod 77 penetrates through the support frame 76 and extends to be connected with a rotating cap, which is convenient for driving the bidirectional threaded rod 77 to rotate stably through the rotating cap. A group of linkage rods 78 are threadedly sleeved on the outer wall of the bidirectional threaded rod 77. The linkage rods 78 can move relatively or oppositely through threaded cooperation with the bidirectional threaded rod 77. The linkage rods 78 are arranged in a "U" shape. One end of the linkage rod 78 penetrates through the support frame 76 and is fixedly connected to the second hopper 75, so as to drive the second hopper 75 to move relatively or oppositely in the first hopper 71. A sealing rubber ring is arranged at the connection between the first hopper 71 and the second hopper 75 to avoid leakage of fine materials such as pulverized coal during the movement, thereby changing the hopper volume and adjusting the material conveying amount.

[0030] In this embodiment, when using this material conveying device for a cogeneration combustion boiler, the motor 4 is turned on, and the output end of the motor 4 drives the transmission roller 2 to rotate through the steering gear 5. The transmission belt 3 between the transmission rollers 2 runs accordingly, and the connecting plate 6 and the hopper assembly 7 fixed on the outer wall of the transmission belt 3 also move together, thereby conveying the material from a low place to a high place.

[0031] When it is necessary to adjust the material conveying capacity of the hopper, the bidirectional threaded rod 77 can be rotated. Since a set of linkage rods 78 are threaded onto the outer wall of the bidirectional threaded rod 77, when the bidirectional threaded rod 77 is rotated, the linkage rods 78, under the constraint of the support frame 76, will drive the second hopper 75 to slide within the first hopper 71 along the direction of the guide groove 73. Because of the cooperation between the guide groove 73 on the guide plate 72 and the guide bar 74, the stability and accuracy of the sliding of the second hopper 75 are ensured, thereby flexibly changing the volume and shape of the hopper and accurately controlling the material conveying capacity.

[0032] During material conveying, the drive belt 3 drives the hopper assembly 7 to transport the material to the designated position. The support rods 8 and legs 9 on both sides of the bracket 1 provide stable support for the entire device, ensuring smooth conveying. After the material conveying work is completed, the motor 4 is turned off, and the device stops operating.

[0033] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
