Description

Technical Field

[0001] The utility model relates to the technical field of feeding of fluidized bed fuel boilers, and particularly relates to an automatic feeding device for a biomass fluidized bed fuel boiler. Background Art

[0002] The automatic feeding device for a biomass fluidized bed fuel boiler is an advanced and efficient automated fuel supply system specially designed for biomass fluidized bed boilers. Its core function is to ensure that biomass fuel can be continuously and stably supplied to the combustion chamber of the boiler, thereby achieving efficient combustion and optimal conversion of thermal energy.

[0003] During the actual operation of the automatic feeding device for a biomass fluidized bed fuel boiler, we noticed that when too much material accumulates at the connection between the elevator and the boiler, a series of potential problems may occur. Specifically, the excessive accumulation of materials at the connection not only easily causes blockage, reducing the feeding efficiency, but also has a negative impact on the combustion efficiency of the boiler. This not only means a reduction in the thermal energy conversion efficiency, but also may lead to energy waste and an exacerbation of environmental pollution problems.

[0004] In addition, the accumulated materials may also exert unnecessary pressure on the connection structure between the elevator and the boiler, which may cause equipment damage or shorten the service life of the equipment. This not only increases the maintenance cost, but also may affect the overall operation stability and safety of the biomass fluidized bed fuel boiler.

[0005] Therefore, in order to give full play to the performance advantages of the automatic feeding device for a biomass fluidized bed fuel boiler, we need to closely monitor the material accumulation situation at the connection between the elevator and the boiler during daily operation, ensure the continuity and stability of material supply, so as to achieve efficient and environmental protection energy utilization.

[0006] The main purpose of the utility model is to provide an automatic feeding device for a biomass fluidized bed fuel boiler, which can effectively solve the problems put forward in the background art.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0008] An automatic feeding device for a biomass fluidized bed fuel boiler includes an assembled feeding pipeline, a first transmission device, a material cylinder, a second transmission device, a driving device, a discharge port, a chain and a material hopper. A plurality of the assembled feeding pipelines are fixed by bolts. The first transmission device and the second transmission device are installed at the upper and lower ends of the plurality of assembled feeding pipelines.

[0014] In a preferred embodiment of the present utility model, the stirring rod is located at the connection between the connecting pipe and the boiler, so that the material can flow quickly to prevent blockage.

[0015] Compared with the prior art, the present utility model has the following beneficial effects:

[0016] In the present utility model, the automatic feeding device makes the feeding process smoother and more efficient through the design of the connecting pipe. The assembled feeding pipe not only facilitates installation, but also can adjust the length and direction according to actual needs to adapt to different working environments.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] As Figure 1 - Figure 4 shown, an automatic feeding device for a biomass fluidized bed fuel boiler has a delicate structure and comprehensive functions, and mainly includes core components such as an assembled feeding pipeline 1, a first transmission device 2, a material cylinder 3, a second transmission device 4, a driving device 5, a discharge port 6, a chain 7 and a material hopper 8. Through a clever design, this device realizes the automatic and efficient feeding of biomass fuel, providing strong support for the operation of the biomass fluidized bed fuel boiler.

[0026] First of all, the assembled feeding pipeline 1 is an important part of this device. It uses multiple pipeline segments to be fixedly connected by bolts. This design is not only convenient for installation and disassembly but also can flexibly adjust the length and direction of the feeding pipeline according to actual needs. At the same time, the assembled feeding pipeline 1 has good sealing performance, which can effectively prevent the leakage and scattering of materials during transportation.

[0027] At the upper and lower ends of the feeding pipeline, a first driving device 2 and a second driving device 4 are respectively installed. Both of these driving devices are composed of gears, rotating shafts and bearings, and are powered by a driving device 5 to achieve the continuous operation of the chain 7. A plurality of material hoppers 8 are arranged on the chain 7, and these material hoppers 8 move along the feeding pipeline driven by the chain 7, thus realizing the automatic feeding of materials.

[0028] The barrel 3, as a component for storing and supplying materials, the materials inside it enter the assembled feeding pipeline 1 through an appropriate way. When the material hopper 8 on the chain 7 passes under the barrel 3, the material hopper 8 will be automatically filled with materials and continue to move forward with the chain 7, and finally send the materials to the discharge port 6.

[0029] The design of the discharge port 6 also fully considers the actual use requirements. At the opening of the discharge port 6, a connecting pipeline 9 is installed. The connecting pipeline 9 adopts a tee pipe structure, which is convenient for connecting with the boiler. At the same time, a rubber ring is provided between the connecting pipeline 9 and the discharge port 6 to ensure the sealing of the connection.

[0030] In addition, the upper end of the connecting pipeline 9 is also connected with a sealing cover 10, and a servo motor 11 is installed on the sealing cover 10. The output end of the servo motor 11 is connected with a stirring rod 12. When the servo motor 11 is started, the stirring rod 12 will rotate in the connecting pipeline 9, thereby preventing the materials from blocking or caking in the pipeline.

[0031] The design of the stirring rod 12 is also quite ingenious. It adopts a combined structure of a main rod, an arc rod and a sleeve. The arc rod is installed on the main rod through the sleeve. This structure enables the stirring rod 12 to be adjusted according to needs to adapt to different materials and conveying conditions. At the same time, the arc rod is made of an elastic metal rod, which has a certain elasticity and toughness and can better adapt to the flow and change of materials during the stirring process.

[0032] Finally, the stirring rod 12 is located at the connection between the connecting pipeline 9 and the boiler, and its rotational movement can effectively promote the flow of materials in the connecting pipeline 9, prevent the materials from blocking or caking, and ensure that the materials can smoothly enter the boiler for combustion.

[0033] Usage process: First, the user needs to install and fix the assembled feeding pipeline 1 according to actual needs to ensure good sealing at the pipeline connection and prevent material leakage. Next, connect the driving device 5 to the power supply and start it to provide power for the first driving device 2 and the second driving device 4. As the driving device 5 operates, the chain 7 starts to move continuously, driving the material hopper 8 to circulate in the feeding pipeline.

[0034] Before starting the feeding, the user needs to ensure that the barrel 3 has stored a sufficient amount of biomass fuel. When the material hopper 8 on the chain 7 passes under the barrel 3, the material hopper 8 will be automatically filled with biomass fuel.

[0035] As the chain 7 continues to operate, the hopper 8 filled with fuel moves along the feeding pipeline and finally reaches the discharge port 6. At the discharge port 6, the connecting pipeline 9 guides the fuel in the hopper 8 into the boiler.

[0036] To ensure the smooth flow of fuel in the connecting pipeline 9, the user can start the servo motor 11 when needed. The servo motor 11 drives the stirring rod 12 to rotate in the connecting pipeline 9, effectively preventing fuel blockage or caking.
