Description
Technical Field
[0001] The present invention relates to the technical field of boiler equipment, and in particular to a high-efficiency energy-saving boiler and a control method thereof. Background Art
[0002] As core thermal energy equipment in industrial production and heating, boilers have always been a focus of industry attention regarding their operating efficiency, energy consumption, and ease of maintenance. Traditional boilers face significant issues with heat transfer and cleaning in the furnace shell over long periods of use. As the core area for combustion and heat exchange, the furnace shell is prone to scaling or dust accumulation on its inner wall after long-term use, increasing thermal resistance and significantly reducing heat transfer efficiency. Maintaining output power requires more fuel, increasing energy consumption and emissions. Traditional cleaning methods rely on manual shutdowns, which are not only time-consuming but may not be thoroughly cleaned due to structural limitations. This leads to high maintenance costs and affects production continuity. Furthermore, traditional boilers often directly inject water through a single pipe, which can easily lead to localized water accumulation, resulting in uneven water temperature distribution within the furnace. Temperatures near the water inlet are relatively low, while areas further away are prone to localized overheating. This not only reduces steam generation efficiency but also accelerates metal fatigue in the furnace shell, shortening equipment life.
[0003] Based on the above problems, the development of a boiler and its control method that can automatically clean the furnace dirt, optimize the water inlet distribution, facilitate maintenance and be highly efficient and energy-saving has become an urgent need for the development of the industry.

[0022] Start the control box 12, preset operating parameters through the control box 12, start the water pump 11 to deliver external water into the body 1 through the water inlet 604 of the connecting column 601, and simultaneously start the second drive motor 6 to drive the spiral dragon conveying blade 605 to rotate, stirring the incoming water and evenly pushing it around the furnace 14; start the burner 4 to burn fuel in the furnace 14 to generate heat, and the heat is transferred to the water medium through the furnace 14 and the threaded smoke pipe 13. The generated steam is output through the main steam valve 15, and the smoke is collected by the front smoke box 2 and discharged from the exhaust pipe 9; The pressure gauge 10 monitors the pressure inside the main body 1 in real time and feeds back to the control box 12. The control box 12 automatically adjusts the fuel supply of the burner 4 according to the pressure data. The temperature sensor monitors the water temperature, and the control box links the water pump 11 to adjust the water flow rate to maintain a stable water temperature. When the boiler runs continuously for a preset period of time or the pressure rises abnormally, the control box 12 automatically starts the first drive motor 5, which drives the reciprocating screw 502 to rotate, and the movable ring 503 makes a reciprocating linear motion along the screw, and drives the scraping ring 505 to slide close to the inner wall of the furnace 14 through the connecting rod 504 to scrape off the scale.

After the pressure in the body 1 drops to a safe value, open the inspection valve 7 to release the pressure. Turn the control block 511 to drive the adjusting screw 510 to rotate, so that the limit screw 513 retracts the column hole 512, and pulls the first drive motor 5 to remove the reciprocating screw 502 and the scraper ring 505 from the furnace 14 to complete the cleaning or replacement of the components.

[0023] In this embodiment, after long-term use of the boiler, dust or scaling is easily accumulated on the inner wall of the furnace 14, affecting the heat conduction efficiency. By starting the first drive motor 5, the reciprocating screw 502 is driven to rotate. The movable ring 503 is threadedly connected to the reciprocating screw 502 and makes reciprocating linear motion along the screw. The cleaning ring 505 is driven by the connecting rod 504 to slide close to the inner wall of the furnace to scrape off the dirt. The limiting device 507 on the flange plate 501 is inserted into the positioning hole 303 of the rear smoke box 3 through the limiting column 508. The rotating control block 511 drives the adjusting screw 510 to rotate, so that the limiting screw 513 extends out and is stuck in the limiting hole 302, fixing the cleaning mechanism to avoid shaking during operation. At the same time, after long-term use of the boiler, the cleaning ring 505 After the inside of the furnace 14 is effectively cleaned, the control block 511 can be turned to drive the adjusting screw 510 to rotate. As the adjusting screw 510 rotates, the limit screw 513 is retracted into the column hole 512, and the first drive motor 5 is pulled at the same time to remove the reciprocating screw 502 and the scraping ring 505 from the inside of the furnace 14, so as to facilitate the cleaning of the reciprocating screw 502, the scraping ring 505 and the inside of the furnace 14. The external water is sent into the boiler through the water inlet 604 of the connecting column 601 by the water pump 11, and the second drive motor 6 drives the spiral dragon conveying blade 605 to rotate, stirring and pushing the incoming water upward, so that the water flow is evenly distributed, avoiding local water temperature imbalance, and improving heat exchange efficiency.
[0024] Working principle: When the water pump 11 delivers external water into the boiler through the water inlet 604 of the connecting column 601, the water inlet pipe adopts a special diversion structure design, and a plurality of evenly distributed diversion holes or diversion branches are set at the water inlet, so that the water can be evenly distributed to various parts of the boiler body 1, avoiding the situation where the local water flow is too large or too small, ensuring that the water temperature in the entire water volume rises evenly, and improving the uniformity and efficiency of heat exchange. The water pump 11 delivers external water into the boiler through the water inlet 604 of the connecting column 601, and the second drive motor 6 drives the spiral dragon conveying blade 605 to rotate, which adjusts the water inlet shape. The combustion engine 4 starts up and burns fuel such as natural gas or oil inside the furnace 14 to generate high-temperature flames and flue gas. The furnace 14, as the main heat-receiving component, directly absorbs the heat of the flame and transfers the heat to the water in the boiler body 1. The flue gas that is not fully utilized enters the threaded flue pipe 13 and connects the front tube plate and the rear tube plate of the combustion chamber. The threaded structure increases the contact area between the flue gas and the tube wall, prolongs the heat exchange time, and further releases heat. Finally, the flue gas is collected by the front smoke box 2 and discharged through the exhaust pipe 9 to reduce heat. Waste, water absorbs heat and heats up to boiling, the generated steam gathers at the top of the body 1, and is output to external equipment through the main steam valve 15, the pressure gauge 10 monitors the pressure in the pot in real time, and the control box 12 adjusts the burner power according to the pressure data to ensure safe operation. After long-term use, the inner wall of the furnace 14 is prone to dust or scaling, which affects the heat conduction efficiency. At this time, the first drive motor 5 is started, driving the reciprocating screw 502 to rotate, and the movable ring 503 is threadedly connected to the reciprocating screw 502, and makes reciprocating linear motion along the screw, and drives the cleaning ring 505 to slide close to the inner wall of the furnace through the connecting rod 504 to scrape off dirt, and the flange plate The limiting device 507 on 501 is inserted into the positioning hole 303 of the rear smoke box 3 through the limiting column 508. The rotating control block 511 drives the limiting screw 513 to rotate, so that the adjusting screw 510 extends and is stuck in the limiting hole 302, fixing the scraping mechanism to avoid shaking during operation. The drain valve 8 regularly discharges the sediment and sewage at the bottom of the pot to prevent impurities from accumulating; the inspection valve 7 is used to empty the medium in the pot when the machine is shut down, which is convenient for internal maintenance. The control box 12 integrates sensor data such as pressure and water temperature, and automatically adjusts the water inlet flow through the water pump and combustion intensity to achieve energy-saving operation. If the pressure is abnormal, the main steam valve 15 can automatically release the pressure.

The high-efficiency energy-saving boiler according to claim 1, characterized in that: A baffle (5021) is fixedly provided on the outer wall of one end of the reciprocating screw (502) away from the first drive motor (5); a ring hole (506) is provided on the inner wall of the movable ring (503); the inner wall of the ring hole (506) is threadedly connected to the outer wall of the reciprocating screw (502); and the outer wall of the scraping ring (505) is slidably connected to the inner wall of the furnace (14) via the first drive motor (5), the reciprocating screw (502), and the movable ring (503).
10. A control method for a high-efficiency energy-saving boiler according to any one of claims 1 to 9, characterized in that: The following steps are involved: The control box (12) is started, and the operating parameters are preset by the control box (12). The water pump (11) is started to deliver external water into the interior of the main body (1) through the water inlet (604) of the connecting column (601). At the same time, the second drive motor (6) is started to drive the spiral dragon conveying blade (605) to rotate, so as to stir the incoming water and evenly push it to the periphery of the furnace (14); the burner (4) is started to burn the fuel in the furnace (14) to generate heat, and the heat is transferred to the water medium through the furnace (14) and the threaded smoke pipe (13). The generated steam is output through the main steam valve (15), and the smoke is collected by the front smoke box (2) and discharged from the exhaust pipe (9); The pressure gauge (10) monitors the pressure inside the main body (1) in real time and feeds back to the control box (12). The control box (12) automatically adjusts the fuel supply of the burner (4) according to the pressure data. The water temperature is monitored by the temperature sensor, and the control box links the water pump (11) to adjust the water flow rate to maintain a stable water temperature. When the boiler runs continuously for a preset time or the pressure rises abnormally, the control box (12) automatically starts the first drive motor (5), the first drive motor (5) drives the reciprocating screw (502) to rotate, the movable ring (503) makes a reciprocating linear motion along the screw, and drives the cleaning ring (505) to slide close to the inner wall of the furnace (14) through the connecting rod (504) to scrape off the scale. During the cleaning process, the limiting device (507) on the flange plate (501) is inserted into the positioning hole (303) of the rear smoke box (3) through the limiting column (508), and the limiting screw (513) is stuck in the limiting hole (302), ensuring the stable operation of the cleaning mechanism; When manual maintenance is required, the burner (4) and the drive motor are turned off, and after the pressure in the body (1) drops to a safe value, the inspection valve (7) is opened to release the pressure; the control block (511) is turned to drive the adjusting screw (510) to rotate, so that the limit screw (513) is retracted into the column hole (512), and the first drive motor (5) is pulled to remove the reciprocating screw (502) and the scraper ring (505) from the furnace (14), completing the cleaning or replacement of the components; the drain valve (8) is opened regularly to discharge the sediment, and after the maintenance is completed, the system is reassembled and started up; If the pressure gauge (10) detects that the pressure exceeds the safety threshold, the control box (12) immediately shuts down the burner (4) and triggers the main steam valve (15) to automatically release the pressure; if the drive motor or transmission components are abnormal, the control box (12) automatically cuts off the power supply to the motor and sends an alarm signal.
