Description

Technical Field

[0001] This utility model relates to the field of coal-fired boiler technology, specifically to a coal-fired boiler load regulation and energy-saving device. Background Technology

[0002] A coal-fired boiler is a device that uses coal as fuel to generate heat energy by burning coal. It transfers the heat from the combustion of coal to water or other media (such as thermal oil), thereby producing steam or hot water for industrial production, heating, power generation, and other purposes. Depending on their application, coal-fired boilers can be divided into power plant boilers, industrial boilers, and residential heating boilers. The principle of a coal-fired boiler is that coal burns in the furnace, releasing heat energy. The high-temperature flue gas produced by combustion transfers heat to water or other media through a heat exchanger, and the heated water becomes steam or hot water for subsequent use.

[0003] In the existing technology, when using coal-fired boilers, although they provide heat or steam, the demand is usually fluctuating. Because the amount of coal fed into the coal-fired boiler cannot be well controlled and adjusted according to the actual load demand, the boiler may not be able to meet the actual demand when the demand is high, while the boiler outputs too much heat when the demand is low, which can easily lead to energy waste and is not conducive to energy saving. Therefore, in order to solve the above problems, a coal-fired boiler load regulation and energy saving device is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a load regulation and energy-saving device for coal-fired boilers, in order to solve the problem mentioned in the background art that, due to the inability to effectively control and adjust the coal feed of the coal-fired boiler according to the actual load demand, the boiler may not be able to meet the actual demand when the demand is high, while the boiler outputs too much heat when the demand is low, which easily leads to energy waste and is not conducive to energy saving.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a load regulation and energy-saving device for a coal-fired boiler, comprising a boiler body, a feed cylinder fixedly connected to the surface of the boiler body, a grate fixedly connected to the inner side of the boiler body, a water inlet pipe fixedly connected to the surface of the boiler body, and a drain pipe fixedly connected to the surface of the boiler body.

[0006] An adjustment mechanism is provided on the inner side of the feed cylinder. The adjustment mechanism includes a support plate, which is fixedly connected to the top of the feed cylinder. A screw is movably connected to the inner side of the support plate and moves within the feed cylinder. A first motor is fixedly installed at the top of the support plate. A sleeve is threadedly connected to the surface of the screw, and a connecting block is fixedly connected to the bottom end of the sleeve.

[0007] Preferably, the adjusting mechanism further includes a limiting rod, which is fixedly connected to the inner wall of the feed cylinder, and a limiting groove is formed on the inner side of the sleeve rod.

[0008] Preferably, the screw is fixedly connected to the output end of the first motor, the sleeve is movable inside the feed cylinder, and the limiting rod and the limiting groove are movably connected.

[0009] Preferably, a cleaning mechanism is provided on the inner side of the boiler body. The cleaning mechanism includes a fixed rod, which is fixedly connected to the inner wall of the boiler body. A fixed block is fixedly connected to the end of the fixed rod away from the boiler body. A first rotating rod is movably connected to the inner side of the fixed block. A first conical tooth is fixedly connected to the surface of the first rotating rod. A second motor is fixedly connected to the surface of the boiler body. A second rotating rod is movably connected to the inner side of the fixed block. A second conical tooth is fixedly connected to the bottom end of the second rotating rod. A scraper is fixedly connected to the surface of the second rotating rod.

[0010] Preferably, the first rotating rod is movable inside the boiler body, and the end of the first rotating rod away from the first conical tooth is fixedly connected to the output end of the second motor.

[0011] Preferably, the second rotating rod moves inside the grate, and both the first and second conical teeth move inside the fixed block.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The first motor drives the screw to rotate, which enables the sleeve rod to move the connecting block vertically. This changes the size of the gap between the connecting block and the inner wall of the feed cylinder, thereby regulating and controlling the coal supply. This ensures that the coal supply meets the actual load requirements of the boiler, reducing coal input when the load decreases, preventing over-combustion, and contributing to energy conservation.

[0014] The second motor drives the first rotating rod to rotate, which in turn rotates the first conical tooth and drives the second conical tooth. This, in turn, enables the second rotating rod to drive the scraper to rotate. The rotation of the scraper can scrape the grate, preventing ash from accumulating on the grate and facilitating better ash removal. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-4 One embodiment provided by this utility model:

[0022] The first motor 22 and the second motor 34 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0023] A load regulation and energy-saving device for a coal-fired boiler includes a boiler body 1. A feed cylinder 11 is fixedly connected to the surface of the boiler body 1, a grate 12 is fixedly connected to the inner side of the boiler body 1, a water inlet pipe 13 is fixedly connected to the surface of the boiler body 1, and a drain pipe 14 is fixedly connected to the surface of the boiler body 1. The feed cylinder 11 allows coal to enter the boiler body 1, the grate 12 allows ash to fall off, thus facilitating ash removal, and the water inlet pipe 13 and drain pipe 14 enable water intake and drainage of the boiler body 1.

[0024] An adjustment mechanism is provided inside the feed cylinder 11. The adjustment mechanism includes a support plate 2, which is fixedly connected to the top of the feed cylinder 11. A screw 21 is movably connected to the inside of the support plate 2. The screw 21 moves inside the feed cylinder 11. A first motor 22 is fixedly installed at the top of the support plate 2. A sleeve 23 is threadedly connected to the surface of the screw 21. A connecting block 24 is fixedly connected to the bottom end of the sleeve 23. The operation of the first motor 22 can drive the screw 21 to rotate, thereby enabling the sleeve 23 to drive the connecting block 24 to move vertically. This allows for adjustment of the gap size of the coal falling, thus dynamically adjusting the coal supply according to the load requirements of the boiler body 1, making the boiler body 1 more energy-efficient.

[0025] Furthermore, the adjustment mechanism also includes a limiting rod 25, which is fixedly connected to the inner wall of the feed cylinder 11. A limiting groove 26 is provided on the inner side of the sleeve rod 23. By setting the limiting rod 25 and opening the limiting groove 26, the sleeve rod 23 can be limited, which can prevent the sleeve rod 23 from shifting under the action of the screw 21, and facilitate the sleeve rod 23 to drive the connecting block 24 to move vertically in a stable manner.

[0026] Furthermore, the output end of the screw 21 and the first motor 22 are fixedly connected, the sleeve 23 is movable inside the feed cylinder 11, and the limiting rod 25 and the limiting groove 26 are movably connected. Through the setting of the sleeve 23, when the sleeve 23 moves vertically under the action of the screw 21, it can drive the connecting block 24 to rise and fall, thereby changing the size of the gap between the connecting block 24 and the inner wall of the feed cylinder 11, which can realize the control of the amount of coal entering.

[0027] Furthermore, a cleaning mechanism is provided on the inner side of the boiler body 1. The cleaning mechanism includes a fixed rod 3, which is fixedly connected to the inner wall of the boiler body 1. A fixed block 31 is fixedly connected to the end of the fixed rod 3 away from the boiler body 1. A first rotating rod 32 is movably connected to the inner side of the fixed block 31. A first conical tooth 33 is fixedly connected to the surface of the first rotating rod 32. A second motor 34 is fixedly connected to the surface of the boiler body 1. A second rotating rod 35 is movably connected to the inner side of the fixed block 31. A second conical tooth 36 is fixedly connected to the bottom end of the second rotating rod 35. A scraper 37 is fixedly connected to the surface of the second rotating rod 35. The rotation of the first rotating rod 32 can drive the first conical tooth 33 to rotate, thereby enabling the second conical tooth 36 to rotate under the action of the first conical tooth 33 and drive the second rotating rod 35 to rotate accordingly. This allows the scraper 37 to rotate and clean the grate 12, making it easier for the ash to fall off the grate 12.

[0028] Furthermore, the first rotating rod 32 is movable inside the boiler body 1. The end of the first rotating rod 32 away from the first conical tooth 33 is fixedly connected to the output end of the second motor 34. Through the setting of the second motor 34, when the second motor 34 drives the first rotating rod 32 to rotate the first conical tooth 33, the first conical tooth 33 can transmit power to the second conical tooth 36, thereby enabling the second rotating rod 35 to drive the scraper 37 to rotate accordingly.

[0029] Furthermore, the second rotating rod 35 is movable inside the grate 12, and the first conical tooth 33 and the second conical tooth 36 are both movable inside the fixed block 31. By setting the second rotating rod 35, the rotation of the second rotating rod 35 can drive the scraper 37 to rotate accordingly. In turn, the rotation of the scraper 37 can scrape the grate 12, which can prevent furnace ash and other materials from accumulating on the grate 12.

[0030] Working principle: In use, the first motor 22 is electrically connected to an external power source. The operator starts the first motor 22 by pressing the switch. The first motor 22 drives the screw 21 to rotate. The sleeve 23 is limited by the limiting rod 25 and the limiting groove 26. Under the action of the screw 21, it will move vertically, thereby realizing the movement of the sleeve 23 on the surface of the limiting rod 25 and the movement of the limiting rod 25 in the limiting groove 26. As a result, the connecting block 24 moves vertically, which changes the size of the gap between the connecting block 24 and the inner wall of the feed cylinder 11, thereby adjusting the coal supply.

[0031] The second motor 34 is electrically connected to an external power source. When the operator starts the second motor 34 by pressing the switch, the second motor 34 drives the first rotating rod 32 to rotate. The first conical tooth 33 rotates under the action of the first rotating rod 32, and then the first conical tooth 33 drives the second conical tooth 36 to rotate, so that the second rotating rod 35 rotates under the action of the second conical tooth 36 and drives the scraper 37 to rotate accordingly. The rotating scraper 37 scrapes the surface of the grate 12 to clean the furnace ash and other materials, thereby preventing the accumulation of furnace ash and other materials.

[0032] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the description above. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model.
