Description

Technical Field

[0001] This utility model relates to the field of boiler load adjustment technology, specifically a device for rapidly adjusting boiler load. Background Technology

[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy. The boiler outputs steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. Boiler load refers to the boiler's ability to produce steam per unit time. For example, boiler steam drives a steam turbine, which then performs work. Essentially, the boiler is doing work; the more work done per unit time, the higher the boiler load, and vice versa. For instance, CN221483672U discloses a device for rapidly adjusting boiler load, including a furnace shell, a coal feeding device, and an air regulating device. A boiler is fixedly connected to the upper end of the furnace shell, a coal hopper is located on one side of the furnace shell, a coal feeding device is installed at the upper end of the coal hopper, and an air regulating device is fixedly connected to one side of the coal hopper. The air regulating device is fixedly connected to a blower via a pipe. The coal feeding device and the air regulating device are located on the same side of the furnace shell. This utility model... The coal feed rate can be adjusted by regulating the rotation speed of the screw rod through the servo motor of the coal feeding device, saving time and effort. The air supply volume can be adjusted by rotating the handle of the air regulating device to control the rotation of the circular baffle. The circular baffle is self-locking through the cooperation of the first and second sliders and the first and second ratchet wheels, preventing valve loosening that could lead to unstable airflow regulation and affect boiler load control, thus improving practicality. However, during use, the varying sizes of coal and other fuels inside the boiler result in uneven combustion, affecting overall control. Furthermore, existing gas supply devices cannot deliver sufficient gas for complete combustion, reducing conversion efficiency and increasing production costs. Therefore, there is an urgent need to design a device for rapidly adjusting boiler load to solve these problems. Utility Model Content

[0012] This device is designed to quickly adjust boiler load. It uses an air pump to deliver gas evenly through a square gas supply pipe and then through four sets of conveying pipes into the boiler body to facilitate complete combustion of fuel and improve combustion efficiency. Each of the four sets of conveying pipes is equipped with a solenoid valve for better adjustment and control of the boiler load. The inclined cut inside the feed pipe facilitates the entry of materials into the combustion chamber and improves efficiency.

[0013] This device for quickly adjusting boiler load uses two sets of crushing rollers installed inside the crushing box to uniformly crush the combustible material, facilitating combustion and improving feeding for easier internal load adjustment. The conveying component can uniformly distribute and transport the crushed material, thereby macroscopically controlling the fuel and better regulating the boiler load. The connecting component allows for linkage, facilitating crushing by the crushing rollers during conveying, saving energy consumption and reducing production costs. Attached Figure Description

A feed pipe 11 is installed on the inner left wall of the boiler body 1. A beveled cut 111 is made at the connection between the feed pipe 11 and the interior of the boiler body 1. An air supply mechanism 3 is installed on the front side of the mounting bracket 2. The air supply mechanism 3 includes an air pump 31, a square air supply pipe 32, and four sets of conveying pipes 33. The square air supply pipe 32 is installed at the front end of the air pump 31, and the four sets of conveying pipes 33 are connected to the rear right side of the square air supply pipe 32. Inside the boiler body 1, a conveying mechanism 4 is installed at the top center of the mounting frame 2. The conveying mechanism 4 includes a conveying box 41, a conveying component 42, and a connecting component 43. The conveying component 42 is inserted into the bottom side of the inside of the conveying box 41. The left end of the conveying component 42 is connected to the connecting component 43. A crushing device 5 is installed at the top of the conveying box 41. The crushing device 5 includes a crushing box 51 and a crushing roller 52. The crushing box 51 is installed at the top of the conveying box 41. Two sets of crushing rollers 52 are installed inside the crushing box 51. The left end of the crushing roller 52 is connected to the connecting component 43.

[0022] As a further feature of this invention, four sets of conveying pipes 33 are installed parallel to each other at equal distances on the inner wall of the boiler body 1. All four sets of conveying pipes 33 are made of heat-resistant material and each set of conveying pipes 33 has a solenoid valve 331 installed in the center of the center, which facilitates the complete combustion of fuel and thus improves combustion efficiency.

[0023] Furthermore, a central horizontal tube groove 412 is horizontally formed at the bottom center of the conveyor box 41, and a central vertical tube groove 411 is vertically formed at the top center of the conveyor box 41. The central vertical tube groove 411 is vertically formed on the left side of the top of the central horizontal tube groove 412. The conveying component 42 includes a feeding pipe 421 and an auger 422. The feeding pipe 421 is connected to the central vertical tube groove 411. A fixed circular plate 424 is fixedly installed on the left side inside the feeding pipe 421. A fixed bearing 423 is installed at the center of the fixed circular plate 424. The left side of the fixed bearing 423 is installed on the left side of the auger 422, and the right side of the auger 422 is installed on the right side. The outer wall of the screw conveyor rotates tightly against the inner wall of the feeding pipe 421. A servo motor 425 is installed on the left end of the screw conveyor 422 to drive the rotation and feed material. The linkage 43 includes a lower sprocket set 431 and a rotating shaft 432. The bottom end of the lower sprocket set 431 is installed on the left end of the screw conveyor 422, and the top end of the lower sprocket set 431 is installed on the left end of the rotating shaft 432. The rotating shaft 432 is inserted into the left wall of the conveying box 41. An upper sprocket set 433 is installed on the right side of the rotating shaft 432 to connect to the crushing roller 52. This is beneficial for the uniform proportioning and conveying of the crushed material, thereby macroscopically controlling the fuel and better adjusting the boiler load.

[0024] Furthermore, a trapezoidal guide trough 511 is installed at the bottom of the crushing box 51. The bottom of the trapezoidal guide trough 511 is connected to the top of the central vertical tube trough 411. Triangular inclined plates 512 are installed at the front and back of the top of the crushing box 51. Two sets of crushing rollers 52 are installed inside the crushing box 51. Gears 521 are fixed on the left side of both sets of crushing rollers 52 for meshing. A sprocket set 433 is connected to the left side of each set of crushing rollers 52. This is beneficial for uniformly crushing the combustible material, facilitating combustion, and improving feeding for easier internal load adjustment.

[0025] Working principle: In use, coal and other fuels are placed inside the crushing box 51 through the triangular inclined plate 512 at the top. Then, the servo motor 425 is powered on to drive the auger 422 installed inside the feeding pipe 421 to rotate. When the auger 422 rotates, it drives the rotating shaft 432 to rotate through the connected lower sprocket set 431. The rotation of the rotating shaft 432 drives the crushing roller 52 to rotate through the upper sprocket set 433. The rotation of a single crushing roller 52 drives another crushing roller 52 to rotate through the connected gear 521, thereby crushing the coal and other fuels. The crushed fuels are then fed into the central vertical pipe groove 411 through the trapezoidal guide trough 511 on the bottom side, and then transported into the boiler body 1 through the auger 422. Then, by controlling the opening of the solenoid valve 331, the gas continuously supplied by the air pump 31 into the square air supply pipe 32 is sent into the boiler body 1 through the conveying pipe 33. This is the complete working principle of this utility model.
