Description

Technical Field

[0001] This utility model relates to the field of boiler furnaces, specifically to a combustion boiler furnace device. Background Technology

[0002] This utility model patent relates to the field of combustion boilers. As an important heat energy conversion device, combustion boilers are widely used in industrial production, heating, and power generation. During the operation of a combustion boiler, the furnace is its core component, and the rationality and stability of its structure directly affect the boiler's combustion efficiency, service life, and maintenance costs.

[0003] In existing technologies, the structural design of combustion boiler furnace devices often has several problems. Firstly, the support ring and base are mostly fixedly connected, making disassembly and cleaning difficult and increasing maintenance complexity and cost. Secondly, the installation method of the hopper-shaped inner wall may be complex, making it difficult to achieve stable and easily disassembled positioning. This not only limits the replacement and maintenance of the hopper-shaped inner wall but may also shorten the overall service life of the device due to wear or damage from long-term use. Furthermore, existing air preheating methods may not be efficient enough, failing to fully utilize the heat generated during combustion to preheat the air entering the furnace, thus affecting the ignition and combustion efficiency of natural gas and making it difficult to create favorable combustion conditions. Therefore, those skilled in the art have provided a combustion boiler furnace device to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned deficiencies and provide a combustion boiler furnace device that solves the technical problems of inconvenient disassembly and cleaning of the combustion boiler furnace and the impact of low air temperature on natural gas combustion efficiency in the prior art through a quick-release mechanism and preheating of the air.

[0005] The objective of this utility model is achieved through the following means:

[0006] A combustion boiler furnace device includes a base and a support ring. The support ring is disposed on the upper side of the base. An air inlet pipe is connected to the outer end of the support ring, and an air outlet is installed on the inner wall of the support ring. A limit ring is installed at the bottom of the support ring and is inserted into the upper end port of the base. A support ring is installed on the inner wall of the base, and a bucket-shaped inner wall is mounted on the support ring. A discharge port is opened on the bottom side of the bucket-shaped inner wall, and air holes are opened on the periphery of the bucket-shaped inner wall. An annular air duct surrounds the outer periphery of the bucket-shaped inner wall, and the output end of the annular air duct is connected to the air holes. A blower is disposed on the outer side of the base, and an air supply pipe is connected to the output end of the blower. The air supply pipe passes through the base and communicates with the annular air duct. A discharge pipe is connected to one side of the bottom of the base. When combustion occurs inside the bucket-shaped inner wall, excess heat is transferred to the bottom space of the base through the bucket-shaped inner wall and the discharge port at the bottom, thereby preheating the annular air duct. This preheats the air inside the annular air duct, increases the air temperature, and helps the natural gas ignite and burn.

[0007] Furthermore, a first positioning post is installed on the inner wall of the limiting ring, and a first positioning groove is opened on the outer wall of the upper end port of the base. The first positioning post is slidably inserted into the first positioning groove, and the first positioning post is docked with the second positioning groove, thereby stably positioning the support ring and facilitating the disassembly and cleaning of the support ring in the future.

[0008] Furthermore, the support ring is fitted to the outer wall of the inner wall of the bucket shape, and a second positioning groove is provided on the upper side of the support ring. A second positioning post is installed on the outer wall of the inner wall of the bucket shape. The second positioning post is inserted into the second positioning groove to position the inner wall of the bucket shape. Since it is an insertion positioning mechanism, the inner wall of the bucket shape can be disassembled, which facilitates the cleaning of the inner wall of the bucket shape in the later stage.

[0009] Furthermore, an adjustment valve is installed on the intake pipe to adjust the intake volume of the intake pipe.

[0010] Furthermore, a check valve is installed inside the air duct to prevent gas from entering the blower, thus protecting the blower and extending its service life.

[0011] Furthermore, the air inlet pipe is connected to the air outlet, and the air is evenly discharged through the annularly arranged air outlet, so that the natural gas is injected into the furnace at high speed and evenly, forming a fine airflow stream, increasing the contact area between natural gas and air, and improving combustion efficiency.

[0012] Furthermore, a motor is installed at the bottom of the base, and a scraper is installed at the output end of the motor facing the inside of the base. The scraper is in contact with the bottom side wall of the base and is arc-shaped. When the motor is started, it drives the scraper to rotate. The scraper can clean the slag at the bottom of the base. Because the scraper is arc-shaped, it can sweep the slag to the edge of the inner cavity of the base during cleaning, and finally discharge the slag from the discharge pipe on one side of the base.

[0013] The beneficial effects of this utility model are as follows: the support ring inside the furnace device is sleeved with the base through the limiting ring, and the inner wall of the bucket shape is supported on the inner wall of the base through the support ring. The two are quick and easy to disassemble and clean in the later stage, which reduces the maintenance difficulty and extends the service life of the device. The blower delivers air to the annular air duct through the air supply pipe. The annular air duct surrounds the inner wall of the bucket shape, and the air holes on the inner wall of the bucket shape are aligned with the annular air duct. During combustion, the heat transferred from the inner wall of the bucket shape and the discharge port to the bottom space of the base preheats the air in the annular air duct, increases the air temperature, helps the ignition and combustion of natural gas, and forms good combustion conditions.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] In this embodiment, refer to Figures 1-4The specific implementation of a combustion boiler furnace device includes a base 1 and a support ring 4. The support ring 4 is disposed on the upper side of the base 1. An air inlet pipe 401 is connected to the outer end of the support ring 4. An air outlet 402 is installed on the inner wall of the support ring 4. A limit ring 404 is installed at the bottom of the support ring 4 and is inserted into the upper end port of the base 1. A support ring 101 is installed on the inner wall of the base 1. A bucket-shaped inner wall 2 is mounted on the support ring 101. A feed port 201 is opened on the bottom side of the bucket-shaped inner wall 2. Air holes 202 are opened on the periphery of the bucket-shaped inner wall 2. An annular air duct 303 surrounds the outer periphery of the bucket-shaped inner wall 2. The output end of the annular duct 303 is connected to the air hole 202. A blower 3 is provided on the outside of the base 1. The output end of the blower 3 is connected to the air supply pipe 301. The air supply pipe 301 passes through the base 1 and communicates with the annular duct 303. A discharge pipe 104 is connected to one side of the bottom of the base 1. When burning in the space inside the bucket-shaped inner wall 102, excess heat is transferred to the bottom space of the base 1 through the bucket-shaped inner wall 102 and the discharge port 201 at the bottom, thereby preheating the annular duct 303. This preheats the air inside the annular duct 303, increases the air temperature, and helps the natural gas to ignite and burn.

[0021] The inner wall of the limiting ring 404 is equipped with a first positioning post 405. The outer wall of the upper end of the base 1 is provided with a first positioning groove 102. The first positioning post 405 is slidably inserted into the first positioning groove 102, and the first positioning post 405 is connected to the second positioning groove 103, thereby stably positioning the support ring 4 and facilitating the disassembly and cleaning of the support ring 4 later. The support ring 101 fits against the outer wall of the funnel-shaped inner wall 2. The upper side of the support ring 101 is provided with a second positioning groove 103. The outer wall of the funnel-shaped inner wall 2 is equipped with a second positioning post 203. The second positioning post 203 is positioned and inserted into the second positioning groove 103, thereby positioning the funnel-shaped inner wall 102. Since it is an insertion positioning mechanism, the funnel-shaped inner wall 102 can be disassembled, thus facilitating the cleaning of the funnel-shaped inner wall 102 later. An adjusting valve 403 is installed on the air inlet pipe 401. The intake volume of the intake pipe 401 is adjusted. A check valve 302 is installed inside the air supply pipe 301 to prevent gas from entering the interior of the blower 3, thus protecting the blower 3 and improving its service life. The intake pipe 401 is connected to the outlet nozzle 402. Gas is evenly discharged through the annularly arranged outlet nozzles 402, so that natural gas is injected into the furnace at high speed and evenly, forming a fine airflow stream, increasing the contact area between natural gas and air, and improving combustion efficiency. A motor 5 is installed at the bottom of the base 1. A scraper 6 is installed at the output end of the motor 5 facing the interior of the base 1. The scraper 6 is in contact with the bottom side wall of the base 1. The scraper 6 is arc-shaped. When the motor 5 is started, it drives the scraper 6 to rotate. The scraper 6 can clean the slag at the bottom of the base 1. Because the scraper 6 is arc-shaped, it can sweep the slag to the edge of the inner cavity of the base 1 during cleaning, and finally discharge the slag from the discharge pipe 104 on one side of the base 1.

[0022] The working principle of this device is as follows: A support ring 4 is provided on the base 1. An air inlet pipe 401 is connected to the outer bottom side of the support ring 4. An regulating valve 403 is provided on the air inlet pipe 401. The air intake of the air inlet pipe 401 can be adjusted by the regulating valve 403. Then, the gas is evenly discharged through the annularly arranged gas outlets 402, so that the natural gas is injected into the furnace in a high-speed and uniform manner, forming a fine airflow jet, increasing the contact area between natural gas and air, and improving combustion efficiency.

[0023] A limiting ring 404 is installed on the bottom side of the support ring 4. A first positioning post 405 is installed on the inner wall of the limiting ring 404. A first positioning groove 102 is opened on the outer wall of the upper end port of the base 1. The support ring 4 is sleeved with the base 1 through the limiting ring 404. During the sleeved connection, the first positioning post 405 is engaged with the second positioning groove 103, thereby stably positioning the support ring 4 and facilitating the disassembly and cleaning of the support ring 4 later.

[0024] A support ring 101 is installed on the inner wall of the base 1. A bucket-shaped inner wall 102 is mounted on the support ring 101. A second positioning post 203 is installed at the upper end of the bucket-shaped inner wall 102. When the bucket-shaped inner wall 102 is supported by the support ring 101, the second positioning post 203 is inserted into the second positioning groove 103 on the inner wall of the base 1 port for positioning, thereby positioning the bucket-shaped inner wall 102. Since it is an insertion positioning mechanism, the bucket-shaped inner wall 102 can be disassembled, which facilitates the cleaning of the bucket-shaped inner wall 102 in the future.

[0025] A blower 3 is provided on one side of the base 1. The output end of the blower 3 is connected to an air supply pipe 301, and the other end of the air supply pipe 301 is connected to an annular air pipe 303. The annular air pipe 303 is located inside the base 1 and surrounds the periphery of the inner wall 102 of the bucket shape. Since the inner wall 102 of the bucket shape is connected to the second positioning groove 103 through the second positioning post 203, the air hole 202 on the inner wall 102 of the bucket shape is aligned with the annular air pipe 303. When the combustion occurs in the space inside the inner wall 102 of the bucket shape, the excess heat is transferred to the bottom space of the base 1 through the inner wall 102 of the bucket shape and the bottom discharge port 201, thereby preheating the annular air pipe 303. This preheats the air inside the annular air pipe 303, increases the air temperature, and helps the natural gas to ignite and burn, thus creating good combustion conditions. A check valve 302 is installed on the air supply pipe to prevent the gas from entering the interior of the blower 3, protecting the blower 3 and improving its service life.

[0026] The discharge port 201 on the bottom side of the inner wall 102 of the bucket is used to discharge the slag during the combustion of natural gas. After the slag falls to the bottom of the base 1, the motor 5 at the bottom of the base 1 starts and drives the scraper 6 inside the base 1 to rotate. The scraper 6 can clean the slag at the bottom of the base 1. Since the scraper 6 is arc-shaped, it can sweep the slag to the edge of the inner cavity of the base 1 during cleaning, and finally discharge the slag from the discharge pipe 104 on one side of the base 1.

[0027] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
