Description

Technical Field

[0001] The invention belongs to the technical field of burners, in particular to a burner with a function of preventing low-temperature flameout. Background Art

[0002] The newly built rotary kiln uses about 900 tons of refractory materials. According to the use characteristics of refractory materials, the refractory materials used in the newly built kiln must be fully baked to completely discharge the moisture in the castables and refractory bricks, so that the temperature of the entire kiln rises to the appropriate temperature for calcining materials. At the same time, the thermal expansion of the refractory brick lining, kiln cylinder, supporting wheels, etc. reaches an appropriate level. In the early stage of kiln ignition, since the ambient temperature of the kiln system is room temperature, the flame is easy to extinguish due to the low ambient temperature after the burner is ignited, which is not conducive to the evaporation of free water in the refractory materials, especially the castables, and affects the service life of the refractory materials.

[0003] The flameout during the kiln baking process has a great impact on the later use of refractory materials, especially after the flameout at the low temperature stage, the moisture in the unburned diesel will drip onto the magnesium-aluminum spinel refractory bricks in the refractory material, and react rapidly with the magnesium in the refractory material, causing greater damage to the refractory material. Therefore, controlling the amount of oil fed is to control the temperature in the combustion chamber, and also to reduce the moisture caused by incomplete combustion of diesel when the amount of oil fed is too much. If this effect is not handled, it will have an adverse effect on the stable operation of the refractory materials in the later kiln system and the normal production of the rotary kiln, resulting in a decrease in the final output and quality of the lime product. According to the above situation, a burner with the function of preventing low-temperature flameout is designed. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems. The present invention provides a burner with the function of preventing low-temperature flameout, which has the advantages of adjustable temperature and saving diesel.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a burner with a function of preventing low-temperature flameout, comprising a combustion chamber, a fan fixedly installed in the middle of the top surface of the combustion chamber, a filter cartridge fixedly connected to the left end of the fan, an air inlet pipe fixedly connected to the right end of the fan, an atomizing nozzle fixedly connected to the bottom surface of the air inlet pipe, an atomizing hood fixedly sleeved at the lower end of the air inlet pipe, a limit sleeve fixedly connected to the lower end of the air inlet pipe, a connecting column fixedly sleeved in the middle of the limit sleeve, a rotating needle fixedly connected to the rear end of the connecting column, a windshield fixedly connected to the front end of the connecting column, an oil supply meter fixedly installed in the middle of the rear side of the combustion chamber, a temperature meter fixedly installed on the left side of the middle of the rear side of the combustion chamber, a combustion chamber door connected to the rear side of the combustion chamber via a hinge, a bearing plate fixedly connected to the right side of the combustion chamber, an oil tank fixedly installed on the top surface of the bearing plate, an oil pipe provided at the lower end of the oil tank, and a valve fixedly installed at the right end of the oil pipe (7).

[0006] The inner side of the rear end of the limiting sleeve is fixedly connected with a second limiting column, the outer side of the front end of the connecting column is fixedly connected with a first limiting column, and the connecting column and the oil supply gauge are movably sleeved.

[0007] The diameter of the wind shield plate is smaller than the cross-sectional diameter of the air inlet pipe, and the wind shield plate can rotate in the air inlet pipe.

[0008] The oil pipe is fixedly connected to the air inlet pipe and the connection of the air inlet pipe is in an "hourglass" shape as a whole.

[0009] A glass observation window is provided on the combustion chamber door, and a handle is fixedly connected to the right end of the combustion chamber door.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The present invention achieves the purpose of adjustable temperature through structures such as connecting columns, wind shields, and limit sleeves. The flame condition and the thermometer are observed through the glass observation window on the combustion chamber door. When the temperature is lower than the required temperature and the flame is flamed out or extinguished, or when the temperature is higher than the required temperature and the flame is flamed out or extinguished, the rotating needle is rotated to rotate the wind shield, thereby increasing the air flow rate in the air inlet pipe, accelerating the diesel being sucked into the air inlet pipe from the oil pipe, increasing the oil output, and thus increasing the diesel atomization amount, ensuring that the torch under the atomizing nozzle head is always in a burning state. When the temperature is higher than the required temperature and has an upward trend and the flame is stable without flamed out, or when the temperature is lower than the required temperature and has an upward trend and the flame is stable without flamed out, the rotating needle is kept stationary, thereby achieving temperature control.

[0012] 2. The present invention achieves the purpose of saving diesel through structures such as an air inlet pipe, an oil pipe, and a wind shield. The state of the connecting column is adjusted in real time by rotating the connecting column. When the wind shield is rotated to a horizontal state, the air-oil mixture will enter the atomizing nozzle from the gap around the wind shield, reducing the amount of diesel atomized by the atomizing nozzle and reducing the flow of air in the upper end of the wind shield. When the wind shield is rotated to a vertical state, the air-oil mixture will increase the amount of entering the atomizing nozzle, thereby increasing the amount of diesel atomized and increasing the flow of air in the upper end of the wind shield. The oil supply amount can be adjusted by adjusting the wind shield, thereby changing the required amount of atomized oil and avoiding unnecessary waste of oil. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The smoke screen is located at the top of the smoke screen, and the smoke screen is located at the bottom of the smoke screen. The smoke screen is located at the top of the smoke screen, and the smoke screen is located at the bottom of the smoke screen.

[0020] As a preferred technical solution of the present invention, a second limiting column is fixedly connected to the inner side of the rear end of the limiting sleeve, and a first limiting column is fixedly connected to the outer side of the front end of the connecting column. The connecting column and the oil filling gauge are movably connected. The windshield at the front end of the connecting column can be rotated by rotating the needle. The first limiting column and the second limiting column cooperate with each other so that the position of the windshield can remain stable after rotation.

[0021] As a preferred technical solution of the present invention, the diameter of the wind shield plate is smaller than the cross-sectional diameter of the air inlet pipe, and the wind shield plate can rotate in the air inlet pipe. When the wind shield plate rotates to a horizontal state, the wind-oil mixture will enter the atomizing nozzle from the gap around the wind shield plate, thereby reducing the amount of diesel atomization of the atomizing nozzle and reducing the flow of air in the upper end of the wind shield plate. When the wind shield plate rotates to a vertical state, the wind-oil mixture will increase the amount of entering the atomizing nozzle, thereby increasing the amount of diesel atomization and increasing the flow of air in the upper end of the wind shield plate.

[0022] As a preferred technical solution of the present invention, the oil pipe is fixedly connected to the air inlet pipe and the connection of the air inlet pipe is an "hourglass" shape as a whole. When the wind shield plate is rotated from a horizontal state to a vertical state, the air flow above the wind shield plate increases. In addition, due to the design of the shape of the connection, the air flow rate will increase at the oil pipe and valve interface. According to the Venturi effect, the diesel will be sucked into the air inlet pipe from the oil pipe, thereby increasing the oil output. Conversely, when the wind shield plate is rotated from a vertical state to a horizontal state, the air flow rate will decrease at the oil pipe and valve interface, thereby reducing the diesel sucked into the air inlet pipe from the oil pipe, thereby reducing the oil output.

[0023] As a preferred technical solution of the present invention, a glass observation window is provided on the combustion chamber door, and a handle is fixedly connected to the right end of the combustion chamber door. The glass observation window can be used to observe whether the combustion chamber is de-fired or extinguished, thereby facilitating the adjustment of the fuel gauge to control the flame and temperature.

[0024] The present invention provides a burner with a function of preventing low-temperature flameout, comprising a combustion chamber, and the operating steps are as follows:

[0025] 1. Operation adjustment basis

[0026] 1) When the temperature is lower than the required temperature and the flame is out of flame or when the temperature is higher than the required temperature and the flame is out of flame or turns off, turn the needle to increase the air flow rate in the air inlet pipe, thereby increasing the diesel atomization amount to ensure that the torch under the atomizing nozzle is always in a burning state.

[0027] 2) When the temperature is higher than the required temperature and has an upward trend and the flame is stable without flameout, or when the temperature is lower than the required temperature and has an upward trend and the flame is stable without flameout, keep the needle stationary.

[0028] 2. Operation adjustment method

[0029] 1) The inner side of the rear end of the limit sleeve is fixedly connected with the second limit column, and the outer side of the front end of the connecting column is fixedly connected with the first limit column. The connecting column and the oil meter are movably connected. By rotating the needle and the connecting column, the windshield at the front end of the connecting column can be rotated. The first limit column and the second limit column work together to ensure that the position of the windshield remains stable after rotation.

[0030] 2) The diameter of the windshield is smaller than the cross-sectional diameter of the air inlet pipe, and the windshield can rotate in the air inlet pipe. When the windshield rotates to a horizontal state, the air-oil mixture will enter the atomizing nozzle from the gap around the windshield, reducing the amount of diesel atomized by the atomizing nozzle and reducing the flow of air in the upper end of the windshield; when the windshield rotates to a vertical state, the amount of air-oil mixture entering the atomizing nozzle will increase, thereby increasing the amount of diesel atomized and increasing the flow of air in the upper end of the windshield.

[0031] 3) The oil pipe is fixedly connected to the air inlet pipe and the connection of the air inlet pipe is an "hourglass" shape. When the windshield is turned from a horizontal state to a vertical state, the air flow above the windshield increases, and the air velocity increases at the oil pipe and valve interface due to the design of the connection shape. According to the Venturi effect, the diesel will be sucked from the oil pipe into the air inlet pipe faster, thereby increasing the oil output; conversely, when the windshield is turned from a vertical state to a horizontal state, the air velocity decreases at the oil pipe and valve interface, thereby reducing the diesel being sucked from the oil pipe into the air inlet pipe, thereby reducing the oil output.

[0032] 4) A glass observation window is provided on the combustion chamber door. A handle is fixedly connected to the right end of the combustion chamber door. The glass observation window can be used to observe whether the combustion chamber is de-fired or extinguished, so as to facilitate the adjustment of the fuel gauge to control the flame and temperature.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 5 As shown, the present invention provides a burner with a function of preventing low-temperature flameout, comprising a combustion chamber 1, a fan 9 is fixedly installed in the middle of the top surface of the combustion chamber 1, a filter cartridge 10 is fixedly connected to the left end of the fan 9, an air inlet pipe 11 is fixedly connected to the right end of the fan 9, an atomizing nozzle 16 is fixedly connected to the bottom surface of the air inlet pipe 11, an atomizing hood 13 is fixedly sleeved at the lower end of the air inlet pipe 11, a limiting sleeve 17 is fixedly connected to the lower end of the air inlet pipe 11, a connecting column 14 is sleeved in the middle of the limiting sleeve 17, a rotating needle 12 is fixedly connected to the rear end of the connecting column 14, a windshield plate 15 is fixedly connected to the front end of the connecting column 14, an oil supply meter 3 is fixedly installed in the middle of the rear side of the combustion chamber 1, a temperature meter 2 is fixedly installed on the left side of the middle of the rear side of the combustion chamber 1, a combustion chamber door 4 is connected to the rear side of the combustion chamber 1 through a hinge, a bearing plate 5 is fixedly connected to the right side of the combustion chamber 1, an oil tank 6 is fixedly installed on the top surface of the bearing plate 5, an oil pipe 7 is provided at the lower end of the oil tank 6, and a valve 8 is fixedly installed at the right end of the oil pipe 7.

[0035] Among them, the inner side of the rear end of the limit sleeve 17 is fixedly connected with the second limit column 19, the outer side of the front end of the connecting column 14 is fixedly connected with the first limit column 18, and the connecting column 14 and the oil supply gauge 3 are movably connected. By rotating the needle 12 and the connecting column 14, the windshield plate 15 at the front end of the connecting column 14 can be rotated. The mutual cooperation between the first limit column 18 and the second limit column 19 ensures that the position of the windshield plate 15 can remain stable after rotation.

[0036] Among them, the diameter of the wind shield plate 15 is smaller than the cross-sectional diameter of the air inlet pipe 11, and the wind shield plate 15 can rotate in the air inlet pipe 11. When the wind shield plate 15 rotates to a horizontal state, the wind and oil mixture will enter the atomizing nozzle 16 from the gap around the wind shield plate 15, reducing the diesel atomization amount of the atomizing nozzle 16 and reducing the flow of air in the upper end of the wind shield plate 15. When the wind shield plate 15 rotates to a vertical state, the wind and oil mixture will increase the amount of entering the atomizing nozzle 16, thereby increasing the diesel atomization amount and increasing the air flow in the upper end of the wind shield plate 15.

[0037] Among them, the oil pipe 7 is fixedly connected to the air inlet pipe 11 and the connection of the air inlet pipe 11 is an "hourglass" shape as a whole. When the wind shield plate 15 is rotated from a horizontal state to a vertical state, the air flow above the wind shield plate 15 increases. In addition, the air flow rate will increase at the interface of the oil pipe 7 and the valve 8 due to the design of the connection shape. According to the Venturi effect, the diesel will be sucked into the air inlet pipe 11 from the oil pipe 7 faster, thereby increasing the oil output. Conversely, when the wind shield plate 15 is rotated from a vertical state to a horizontal state, the air flow rate will decrease at the interface of the oil pipe 7 and the valve 8, thereby reducing the diesel sucked into the air inlet pipe 11 from the oil pipe 7, thereby reducing the oil output.

[0038] Among them, a glass observation window is opened on the combustion chamber door 4, and a handle is fixedly connected to the right end of the combustion chamber door 4. The glass observation window can be used to observe whether the combustion chamber is de-fired or extinguished, so as to facilitate the adjustment of the oil supply gauge 3 to control the flame and temperature.

[0039] The working principle and use process of the present invention:

[0040] Observe the flame condition and thermometer through the glass observation window on the combustion chamber door 4. When the temperature is lower than the required temperature and the flame is flamed out or extinguished, or when the temperature is higher than the required temperature and the flame is flamed out or extinguished, rotate the needle 12 to rotate the wind shield plate 15, increase the air flow rate in the air inlet pipe 11, which will accelerate the diesel being sucked into the air inlet pipe 11 from the oil pipe 7, increase the oil output, and thus increase the diesel atomization amount, ensuring that the torch under the atomizing nozzle 16 is always in a burning state. When the temperature is higher than the required temperature and has an upward trend and the flame is stable without flameout, or when the temperature is lower than the required temperature and has an upward trend and the flame is stable without flameout, keep the needle 12 stationary to achieve the control temperature.
