Description

Technical Field

[0001] This utility model relates to the field of burner technology, and in particular to a burner used in the production of artificial leather. Background Technology

[0002] In the production of artificial leather, surface treatment requires melting and shaping the PVC or PU coating at high temperatures. Traditional processes use electrically heated rollers or hot air circulation systems. Electrically heated rollers suffer from large temperature gradients and high energy consumption, while hot air systems result in poor coating uniformity due to airflow disturbances. In recent years, gas-fired direct-fired burners have gradually replaced traditional methods. These burners use direct flame radiation for heating, improving thermal efficiency by approximately 30%. However, existing burners generally suffer from insufficient flame stability and uneven temperature distribution.

[0003] In the prior art, some devices have a fuel inlet on one side and an air inlet nearby, but they are controlled by only a single check valve and a switching valve. This makes it impossible to control the mixing ratio of fuel gas and air, thus affecting combustion efficiency. Utility Model Content

[0004] This invention proposes a burner for use in the production of artificial leather, aiming to improve the problem in some existing devices where the single fuel gas cannot be mixed with air in a controlled ratio, thus affecting combustion efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A burner for use in the production of artificial leather includes a burner frame, a blower mechanism installed on one outer side of the burner frame, a mixing chamber fixedly connected to the other outer side of the burner frame, a mixing mechanism installed outside the mixing chamber, a sealing assembly disposed inside the burner frame, and an ignition mechanism disposed at the bottom of the burner frame. The mixing mechanism includes a connecting pipe a and a connecting pipe b. The outer side of the connecting pipe a is fixedly connected to the outer side of the mixing chamber, the top of the connecting pipe b is fixedly connected to the bottom of the mixing chamber, a connecting pipe a is installed parallel to the connecting pipe a, an air intake regulating valve a is fixedly connected to the top of the connecting pipe a, and the regulating port of the air intake regulating valve a is disposed inside the connecting pipe a. A connecting pipe b is installed vertically to the connecting pipe b, an air intake regulating valve b is fixedly connected to the outer side of the connecting pipe b, and the regulating port of the air intake regulating valve b is disposed inside the connecting pipe b.

[0007] The above scheme involves a mixing mechanism in the burner used for artificial leather production. Connector a is fixed to the outside of the mixing chamber, and connector b is fixed to the bottom of the mixing chamber. Intake regulating valves a and b are installed on both via connecting pipes a and b, respectively, with the regulating ports located inside the corresponding connecting pipes. This structural design allows for independent and precise flow regulation and control of materials entering from the side and bottom of the mixing chamber via intake regulating valves a and b, ensuring uniform mixing of materials within the mixing chamber. This guarantees stable and efficient combustion within the burner, providing a stable heat source for subsequent artificial leather production, effectively improving the quality and efficiency of artificial leather production while reducing energy consumption.

[0008] As a further description of the above technical solution:

[0009] The burner frame includes an outer shell a, a middle connecting shell fixedly connected to one side of the outer shell a, and a tail nozzle fixedly connected to one side of the middle connecting shell.

[0010] Through the above scheme: the outer shell a can protect and support the internal components of the burner; the middle connecting shell realizes the reliable connection between the outer shell a and the tail nozzle, which facilitates the assembly and disassembly of each component; and the tail nozzle can directionally spray out the heat or airflow generated by combustion. This layered structural design not only enhances the overall structural strength and stability of the burner, but also ensures the smooth transmission of airflow and the reasonable distribution of heat during combustion. It provides structural protection for the stable heat source required in the artificial leather production process, enabling the burner to maintain reliable performance in long-term operation and improving the continuity and quality stability of artificial leather production.

[0011] As a further description of the above technical solution:

[0012] The blower mechanism includes a drive motor, one side of which is mounted on the outside of the housing a. The drive motor is fixedly connected to a drive shaft, and a fan blade worm gear is fixedly connected to the outside of the drive shaft. The fan blade worm gear rotates inside the housing a. A reinforced mounting chassis is provided between the drive motor and the housing a.

[0013] The above-described design, which connects the drive end to the drive shaft and drives the fan blade worm gear to rotate inside the housing a, with a reinforced mounting chassis between the drive motor and housing a, allows the drive motor to provide stable power, enabling the fan blade worm gear to rotate efficiently and generate sufficient airflow. The reinforced mounting chassis enhances the stability of the connection between the drive motor and housing a, reducing vibration and noise during operation. This design ensures the stable operation of the blower mechanism itself and provides a continuous and stable airflow to the burner, allowing for thorough mixing of air and fuel during combustion to improve combustion efficiency. This provides a stable and sufficient heat source for artificial leather production and reduces energy consumption. Furthermore, the reinforced mounting chassis extends the service life of the blower mechanism, ensuring long-term reliable operation of the burner.

[0014] As a further description of the above technical solution:

[0015] The sealing assembly includes a sealing plate a and a sealing plate b. The two sides of the sealing plate a are fixedly connected between the outer shell a and the middle connecting shell, and the two sides of the sealing plate b are fixedly connected between the middle connecting shell and the tail nozzle.

[0016] The above solution involves sealing the connections between different components of the burner frame using sealing plates a and b, effectively preventing the leakage of high-temperature gas or fuel gas from the connections during combustion. This ensures the sealing and stability of the combustion environment inside the burner, preventing heat loss and improving combustion efficiency. It also reduces safety hazards caused by gas leakage, enabling the burner to maintain reliable sealing performance under high pressure or high temperature conditions. This, in turn, ensures a stable heat source supply during the artificial leather production process and extends the overall service life of the burner.

[0017] As a further description of the above technical solution:

[0018] The ignition mechanism includes an igniter, the top of which is fixedly connected to the bottom of the middle connecting housing, and a protective conductive tube is fixedly connected to the top of the igniter. The protective conductive tube is disposed inside the tail nozzle.

[0019] The above solution ensures accurate ignition and easy contact between the igniter and the gas mixture in the combustion chamber by securely mounting the igniter at the bottom of the middle connecting housing. The protective conductive tube protects the conductive components of the igniter from the influence of environmental factors such as high temperature and dust on the ignition function. This design not only ensures that the igniter can reliably ignite the gas mixture under complex working conditions, but also improves the safety and durability of the ignition mechanism through the protective conductive tube. This makes the burner start-up process smooth and the combustion state stable, providing continuous and reliable ignition support for artificial leather production and reducing production interruptions caused by ignition failures, thereby improving overall production efficiency and equipment reliability.

[0020] As a further description of the above technical solution:

[0021] An ignition head is fixedly connected to the front end of the protective conductive tube, and multiple metal support frames are fixedly connected to the outside of the protective conductive tube. The outside of the multiple metal support frames is in contact with the inner wall of the tail nozzle.

[0022] The above solution, through a structural design where multiple metal support frames contact the inner wall of the tail nozzle, securely supports the protective conductive tube inside the tail nozzle and maintains the precise position of the ignition head. This prevents the ignition head from shifting or shaking due to airflow impact or equipment vibration. Simultaneously, the contact between the metal support frames and the inner wall of the tail nozzle enhances the stability and reliability of the protective conductive tube installation, ensuring the ignition head maintains good working condition in the high-temperature, high-pressure combustion environment. This guarantees accurate and reliable ignition to quickly ignite the gas mixture, thereby ensuring the stability and continuity of the burner's combustion process.

[0023] As a further description of the above technical solution:

[0024] An air intake pipe is fixedly connected to one side of the bottom of the outer casing a, and a purification mechanism is fixedly connected to the bottom of the air intake pipe.

[0025] The above solution involves introducing external air into the burner through an air intake pipe, where it is filtered by a purification mechanism to effectively remove dust, impurities, and other pollutants. This prevents pollutants from entering the burner and causing wear or blockage to components such as the blower and mixing mechanism. It ensures the cleanliness of the air during combustion, promoting thorough mixing and combustion of fuel and clean air. This not only improves combustion efficiency and reduces energy waste but also lowers the maintenance frequency and wear of internal burner components.

[0026] As a further description of the above technical solution:

[0027] The purification mechanism includes a purifier housing, the top of which is fixedly connected to the bottom of the air intake pipe, the bottom of which is fixedly connected to an air intake port, and the inner wall of which is fixedly connected to multiple activated carbon filter plates.

[0028] The above solution involves forming an independent air filtration chamber through the purifier's outer shell. The activated carbon filter plate's adsorption properties are used to perform multi-layer filtration on the air entering from the purifier's air inlet, effectively removing pollutants such as dust, odors, and harmful gases from the air, thus keeping the air entering the burner clean.

[0029] This utility model has the following beneficial effects:

[0030] 1. In this utility model, a mixing mechanism is adopted, which consists of two parts. Each part is used in conjunction with an air intake regulating valve, so that the ratio of fuel gas and catalytic gas can be precisely controlled. When the ratio is sufficient, the combustion efficiency of the device can be fully utilized.

[0031] 2. In this utility model, a purification mechanism is provided at the bottom of the device, thereby purifying the air at the bottom of the air intake pipe. This mechanism can adsorb impurities and carbon dioxide in the air to a certain extent, preventing impurities from burning and producing dirt on the inner wall of the tail nozzle, and preventing a high proportion of carbon dioxide from affecting combustion efficiency.

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.

[0040] Reference Figures 1 to 3 This utility model provides an embodiment of a burner for artificial leather production, comprising a burner frame 1, a blower mechanism 2 installed on one side of the burner frame 1, a mixing chamber 3 fixedly connected to the other side of the burner frame 1, a mixing mechanism 4 installed on the outside of the mixing chamber 3, a sealing assembly 5 disposed inside the burner frame 1, and an ignition mechanism 6 disposed at the bottom of the burner frame 1. The mixing mechanism 4 includes a connecting pipe a401 and a connecting pipe b404, with the outer side of the connecting pipe a401 fixedly connected to the mixing chamber 3. On the outer side, the top of the connecting pipe b404 is fixedly connected to the bottom of the mixing chamber 3.

An air intake regulating valve b406 is fixedly connected to the outer side of the connecting pipe b405. The regulating port of the air intake regulating valve b406 is located inside the connecting pipe b405.

[0041] Specifically, the intake regulating valves a403 and b406 independently and precisely regulate and control the flow of materials entering from the side connecting pipe a401 and bottom connecting pipe b404 of the mixing chamber 3, respectively. This allows different materials to be uniformly mixed in the mixing chamber 3 according to production requirements, thereby ensuring a stable and efficient combustion process inside the burner frame 1. This provides a continuous and stable heat source for artificial leather production, effectively improving the controllability and stability of heat source supply during artificial leather production and reducing energy loss caused by uneven material mixing.

[0042] The burner frame 1 includes an outer shell a101, a middle connecting shell 102 is fixedly connected to one side of the outer shell a101, and a tail nozzle 103 is fixedly connected to one side of the middle connecting shell 102.

The fan blade worm gear 203 rotates inside the outer shell a101. A reinforced mounting chassis 204 is provided between the drive motor 201 and the outer shell a101.

[0043] Specifically, the burner frame 1 forms a stable overall frame, providing reliable support and protection for the internal mechanisms. In the blower mechanism 2, the drive motor 201 drives the fan blade worm gear 203 to rotate through the drive shaft 202 to generate airflow. The reinforced mounting chassis 204 enhances the stability of the connection between the drive motor 201 and the outer casing a101, reduces vibration and noise during operation, ensures the stable operation of the blower mechanism 2, and provides a continuous and stable airflow to the burner.

[0044] Reference Figure 1 , Figure 4 The sealing assembly 5 includes a sealing plate a501 and a sealing plate b502. The two sides of the sealing plate a501 are fixedly connected between the outer shell a101 and the middle connecting shell 102. The two sides of the sealing plate b502 are fixedly connected between the middle connecting shell 102 and the tail nozzle 103. The ignition mechanism 6 includes an igniter 601. The top of the igniter 601 is fixedly connected to the bottom of the middle connecting shell 102. A protective conductive tube 602 is fixedly connected to the top of the igniter 601. The protective conductive tube 602 is disposed inside the tail nozzle 103. An ignition head 603 is fixedly connected to the front end of the protective conductive tube 602. Multiple metal support frames 604 are fixedly connected to the outside of the protective conductive tube 602. The outside of the multiple metal support frames 604 is in contact with the inner wall of the tail nozzle 103.

[0045] Specifically, the sealing structure effectively prevents the leakage of high-temperature gases inside the burner, ensuring a stable combustion environment, improving combustion efficiency, reducing heat loss, and mitigating safety hazards caused by gas leakage. The igniter 601 of the ignition mechanism 6 is fixed at the top to the bottom of the middle connecting housing 102. The protective conductive tube 602 at the top of the igniter 601 is located inside the tail nozzle 103. An ignition head 603 is located at the front end of the protective conductive tube 602. Multiple external metal support frames 604 contact the inner wall of the tail nozzle 103. This ignition mechanism 6, through its stable installation, ensures the precise ignition position of the ignition head 603, preventing ignition effect from being affected by ignition head 603 misalignment. Simultaneously, the protective conductive tube 602 protects the conductive components of the igniter 601, and the metal support frames 604 enhance the stability of the protective conductive tube 602, enabling the ignition mechanism 6 to operate reliably under complex conditions, ensuring the burner can start smoothly and maintain stable combustion.

[0046] Reference Figure 1 , Figure 5 An air intake pipe 7 is fixedly connected to one side of the bottom of the outer shell a101. A purification mechanism 8 is fixedly connected to the bottom of the air intake pipe 7. The purification mechanism 8 includes a purifier shell 801. The top of the purifier shell 801 is fixedly connected to the bottom of the air intake pipe 7. A purifier air inlet 802 is fixedly connected to the bottom of the purifier shell 801. Multiple activated carbon filter plates 803 are fixedly connected to the inner wall of the purifier shell 801.

[0047] Specifically, external air enters the purifier housing 801 through the purifier inlet 802. The activated carbon filter plate 803 performs multi-layer filtration to remove dust, odors, and harmful gases. The purified air then enters the burner frame 1 through the air intake pipe 7, preventing pollutants from entering the burner and reducing wear on components such as the blower mechanism 2 and mixing mechanism 4. This ensures thorough mixing and efficient combustion of air and fuel during combustion, improving combustion efficiency, reducing equipment maintenance costs and frequency, extending burner lifespan, and creating a clean operating environment for the burner. It provides a clean and stable air supply for artificial leather production, ensuring the safety and continuity of the production process. Combined with precise flow regulation and control in the mixing mechanism 4, this further enhances the stability of heat source supply in artificial leather production, effectively reducing production quality problems caused by unclean air.

[0048] Working principle: When the burner is working, external air enters the purifier housing 801 of the purification mechanism 8 through the purifier inlet 802. After being filtered by multiple activated carbon filter plates 803 to remove impurities such as dust, odors, and harmful gases, it enters the housing a101 of the burner frame 1 through the air intake pipe 7. The drive motor 201 of the blower mechanism 2 starts, and the drive end drives the drive shaft 202 to rotate. The drive shaft 202 then drives the fan blade worm gear 203 to rotate inside the housing a101, blowing the purified air into the burner. At the same time, the mixing mechanism 4, through the connecting pipe a401 and The connecting pipe b404 receives materials from the side and bottom of the mixing chamber 3 respectively. The intake regulating valve a403 and intake regulating valve b406 precisely regulate the material flow rate, so that the material is uniformly mixed in the mixing chamber 3 and then enters the burner frame 1. The igniter 601 of the ignition mechanism 6 is activated, and the material-air mixture in the mixing chamber is ignited by the ignition head 603 at the front end of the protective conductive tube 602. Under the action of the sealing plate a501 and sealing plate b502 of the sealing assembly 5, a stable combustion environment is ensured inside the burner. The heat or airflow generated by combustion is directionally ejected through the tail nozzle 103.
