Description

Technical Field

[0001] The invention relates to the technical field of copper smelting, in particular to a pure oxygen burner provided with a porous regulating structure for a copper smelting anode furnace. Background Art

[0002] Copper is a common metal material, which is widely used in fields such as construction, manufacturing and electronic technology. The rational smelting of copper can promote the development of the copper industry, reduce dependence on imported copper and improve self-sufficiency.

[0003] In the copper smelting process, an anode furnace is needed. When the anode furnace is working, it refines crude copper and high-purity scrap copper into anode copper. When the anode furnace is used, it has the effects of production efficiency and economies of scale, and also has the advantages of reducing energy consumption and reducing production costs. When the anode furnace is used, it needs to be used synchronously with the pure oxygen burner;

[0004] When the pure oxygen burner is in use, pure oxygen is used as a combustion-supporting medium to enable more complete combustion inside the anode furnace. When the anode furnace and the pure oxygen burner are working, the firepower needs to be adjusted according to the actual situation. If the firepower is wrong, it will affect the result of copper smelting.

[0005] In order to overcome the above defects, prior art 1 (application number CN201610276049.9, application date 2016-04-29 Chinese patent) is an adjustable pure oxygen burner, which can adjust the flame length to achieve the best heating effect when the total amount of gas and oxygen remains unchanged, while saving energy and reducing emissions, improving the quality of heating products, ensuring the safety of kiln operation, and increasing the service life of kiln equipment;

[0006] And prior art 2 (application number CN201620521367.2, application date 2016-06-01 Chinese patent) is a porous structure adjustable pure oxygen burner, inside which both gas and oxygen are sprayed and burned through pipes arranged in a ring, and the gas pipe and oxygen pipe are spaced apart, so the combustion process is more thorough, which can effectively reduce the emission of nitrogen oxides, and can effectively realize the flow distribution of gas in the gas pipe and the central gas pipe, and the flame length and width can be adjusted while the gas and oxygen supply remain unchanged, which is simple, reliable and stable. And it has a large adjustment range and good performance;

[0007] During use, if oxygen and fuel are not mixed sufficiently, it will not only lead to a decrease in combustion efficiency, but also increase energy consumption. During use, the device in the above application does not have a good material mixing function, which leads to increased pollution during emissions and affects the quality of the final copper smelting products.

[0008] In view of the above problems, it is urgent to carry out innovative design based on the original pure oxygen burner for copper smelting anode furnace. Summary of the invention

[0009] The purpose of the present invention is to provide a pure oxygen burner with a porous adjustment structure for a copper smelting anode furnace, so as to solve the problem proposed in the above background technology that during use, it does not have a good material mixing function, which leads to increased emission pollution and affects the quality of the final copper smelting product.

[0010] To achieve the above object, the present invention provides the following technical solution: A pure oxygen burner with a porous adjustment structure for a copper smelting anode furnace, comprising a housing and a first bevel gear, a fuel inlet pipe is fixedly connected to the upper surface of the housing, a discharge pipe is fixedly connected to the right side of the housing, and a motor is bolted to the outer wall of the housing;

[0011] The first bevel gear is fixedly connected to the output end of the motor;

[0012] A pure oxygen burner with a porous adjustment structure for a copper smelting anode furnace, further comprising:

[0013] A transition plate, the transition plate is fixedly connected to the lower surface of the shell, a threaded rod is rotatably arranged inside the transition plate, and a limit rod is fixedly connected to the inner wall of the transition plate;

[0014] An oxygen inlet pipe, the oxygen inlet pipe is fixedly connected to the lower surface of the transition plate, and a docking port is provided on the lower surface of the transition plate;

[0015] A discharge pipe, the discharge pipe being fixedly connected to the outer wall of the shell;

[0016] An auxiliary plate, wherein the auxiliary plate is fixedly connected to the inner wall of the shell, and a connecting shaft is rotatably arranged inside the auxiliary plate, and a rotating blade is fixedly connected to the surface of the connecting shaft;

[0017] A fixing plate, the fixing plate being fixedly connected to the inner wall of the shell;

[0018] A knocking block is slidably arranged inside the shell.

[0019] Preferably, the oxygen inlet pipes are distributed at equal intervals on the lower surface of the transition plate, and the oxygen inlet pipes correspond to the docking ports one by one;

[0020] Through the design of the above structure, oxygen can enter the interior of the transition plate through the oxygen inlet pipe and the docking port, and then the oxygen enters the outer shell through the transition plate.

[0021] Preferably, a slide plate is threadedly connected to the surface of the threaded rod, and a baffle plate is fixedly connected to the lower surface of the slide plate, and the baffle plate corresponds to the docking port one by one.

[0022] Preferably, the limiting rods penetrate the interior of the slide plate, and the limiting rods are symmetrically distributed about the center of the slide plate;

[0023] Through the design of the above structure, when the staff needs to adjust the oxygen intake during use, they can rotate the threaded rod inside the transition plate. At this time, the threaded rod cooperates with the limit rod to make the slide plate and the baffle slide inside the transition plate, thereby adjusting the inlet volume of the oxygen inlet pipe and the docking port, making it convenient for the staff to adjust the firepower according to the actual situation.

[0024] Preferably, a second bevel gear meshing with the first bevel gear is fixedly connected to the end of the connecting shaft, and the second bevel gear is symmetrically distributed about the center of the first bevel gear;

[0025] Through the design of the above structure, when the motor is working, the motor drives the connecting shaft to rotate inside the auxiliary plate through the first bevel gear and the second bevel gear. When the connecting shaft rotates, it will drive the rotating blades to rotate synchronously, so that the fuel and oxygen can be better mixed.

[0026] Preferably, a connecting plate is fixedly connected to the surface of the connecting shaft, and a first magnet is fixedly connected to the surface of the connecting plate, and the first magnets are distributed at equal angles on the surface of the connecting plate;

[0027] Through the design of the above structure, when the connecting shaft rotates, the connecting plate and the first magnet will be driven to rotate synchronously.

[0028] Preferably, a column is fixedly connected to the inner wall of the shell, and a toggle plate is sleeved on the surface of the column, and a vent hole is opened on the surface of the toggle plate. The connecting shaft is rotatably arranged inside the toggle plate, and the connecting shaft does not contact the toggle plate.

[0029] Preferably, a second magnet corresponding to the first magnet is fixedly connected to the surface of the toggle plate, and the magnetic poles corresponding to the first magnet and the second magnet are the same.

[0030] Preferably, a connecting spring having an elastic reset function is fixedly connected to the surface of the toggle plate, and the other side of the connecting spring is fixedly connected to the surface of the fixed plate;

[0031] Through the design of the above structure, during the rotation of the connecting shaft, the connecting plate will be driven to rotate synchronously. When the connecting plate rotates, it will drive the first magnet to intermittently approach the second magnet, and then the toggle plate will make reciprocating linear motion in the vertical direction under the action of the mutually repulsive magnetic force, the connecting spring and the column. At this time, the toggle plate also plays a role in disturbing the airflow, which facilitates the mixing of fuel and oxygen.

[0032] Preferably, a side plate is fixedly connected to the side of the upper toggle plate, and a knocking block corresponding to the discharge pipe is fixedly connected to the upper surface of the side plate, and the knocking blocks are evenly spaced on the upper surface of the side plate;

[0033] Through the design of the above structure, when working, the discharge pipe is closed, and the fuel and oxygen are mixed and discharged through the discharge pipe. When impurities need to be removed, the discharge pipe is closed and the discharge pipe is opened. At this time, the smoke is discharged from the discharge pipe. When the toggle plate at the upper end moves, it will drive the side plate and the knocking block to move synchronously. When the knocking block moves, it will intermittently hit the discharge pipe, so that fewer impurities remain inside the discharge pipe.

[0034] Compared with the prior art, the invention has the following beneficial effects: the pure oxygen burner with a porous adjustment structure for the copper smelting anode furnace adopts a new structural design, and the size of the air intake can be quickly adjusted by a movable baffle, so that the staff can adjust the firepower according to the actual situation. In addition, a material mixing structure is provided, which can fully mix the fuel and oxygen, improve the combustion efficiency, and reduce the generation of debris. At the same time, an auxiliary material discharge structure of the discharge pipe is provided to reduce the residual impurities. The specific contents are as follows:

[0035] (1) The pure oxygen burner with a porous adjustment structure for the copper smelting anode furnace can be used to adjust the oxygen intake during use by rotating the threaded rod inside the transition plate. At this time, the threaded rod cooperates with the limit rod to make the slide plate and the baffle slide inside the transition plate, thereby adjusting the oxygen intake pipe and the docking port inlet volume, which is convenient for the staff to adjust the firepower according to the actual situation;

[0036] (2) The copper smelting anode furnace uses a pure oxygen burner with a porous adjustment structure. When working, the motor is started, and the motor drives the connecting shaft to rotate through the first bevel gear and the second bevel gear. When the connecting shaft rotates, the rotating blades are driven to rotate synchronously. At this time, the rotating blades play a role in mixing fuel and oxygen, which facilitates the subsequent full combustion of fuel and oxygen;

[0037] Furthermore, during the rotation of the connecting shaft, the connecting plate will be driven to rotate synchronously. When the connecting plate rotates, the first magnet will be driven to approach the second magnet intermittently, and then the toggle plate will make reciprocating linear motion in the vertical direction under the action of the repulsive magnetic force, the connecting spring and the column. At this time, the toggle plate also plays a role in disturbing the airflow, which is convenient for mixing fuel and oxygen.

[0038] Furthermore, on the surface of the toggle plate, air holes are evenly spaced to allow airflow to flow more easily, thereby preventing the airflow from being unsmooth.

[0039] (3) The copper smelting anode furnace uses a pure oxygen burner with a porous adjustment structure. When working, the discharge pipe is closed. At this time, the fuel and oxygen are mixed and discharged through the discharge pipe. When impurities need to be removed, the discharge pipe is closed and the discharge pipe is opened. At this time, the flue gas is discharged from the discharge pipe. When the toggle plate at the upper end moves, it will drive the side plate and the knocking block to move synchronously. When the knocking block moves, it will intermittently hit the discharge pipe, so that fewer impurities remain in the discharge pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] 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.

[0051] Embodiment 1: By setting a movable baffle 9, the area size of the docking port 11 can be adjusted, and then the staff can adjust the oxygen intake according to the actual situation, which improves the flexibility, such as Figure 1-Figure 4 As shown:

[0052] A pure oxygen burner with a porous adjustment structure for a copper smelting anode furnace, comprising a housing 1 and a first bevel gear 13, a fuel inlet pipe 2 is fixedly connected to the upper surface of the housing 1, a discharge pipe 3 is fixedly connected to the right side of the housing 1, a motor 4 is bolted to the outer wall of the housing 1, and the first bevel gear 13 is fixedly connected to the output end of the motor 4;

[0053] A pure oxygen burner with a porous adjustment structure for a copper smelting anode furnace, further comprising:

[0054] A transition plate 5, the transition plate 5 is fixedly connected to the lower surface of the shell 1, and a threaded rod 6 is rotatably arranged inside the transition plate 5, and a limit rod 8 is fixedly connected to the inner wall of the transition plate 5, and an oxygen inlet pipe 7, the oxygen inlet pipe 7 is fixedly connected to the lower surface of the transition plate 5, and a docking port 11 is opened on the lower surface of the transition plate 5;

[0055] A discharge pipe 12, the discharge pipe 12 is fixedly connected to the outer wall of the housing 1, an auxiliary plate 14, the auxiliary plate 14 is fixedly connected to the inner wall of the housing 1, and a connecting shaft 15 is rotatably arranged inside the auxiliary plate 14, and a rotating blade 17 is fixedly connected to the surface of the connecting shaft 15;

[0056] The fixing plate 19 is fixedly connected to the inner wall of the shell 1, the knocking block 27 is slidably arranged inside the shell 1, and the oxygen inlet pipes 7 are evenly spaced on the lower surface of the transition plate 5, and the oxygen inlet pipes 7 correspond to the docking ports 11 one by one.

[0057] The surface of the threaded rod 6 is threadedly connected to the slide plate 10, and the lower surface of the slide plate 10 is fixedly connected to the baffle plate 9, and the baffle plate 9 corresponds to the docking port 11 one by one. The limit rod 8 runs through the interior of the slide plate 10, and the limit rod 8 is symmetrically distributed about the center of the slide plate 10.

[0058] During operation, the shell 1 takes in fuel through the fuel inlet pipe 2, and takes in oxygen through the oxygen inlet pipe 7 and the docking port 11. During the use of the shell 1 and the discharge pipe 3, when it is necessary to adjust the oxygen intake amount, the threaded rod 6 inside the transition plate 5 can be rotated. At this time, the threaded rod 6 cooperates with the limit rod 8 to make the slide plate 10 and the baffle 9 slide inside the transition plate 5, thereby adjusting the inlet amount of the oxygen inlet pipe 7 and the docking port 11, which is convenient for the staff to adjust the firepower according to the actual situation, and the overall flexibility of the device is high.

[0059] Embodiment 2: Different from Embodiment 1, the fuel and oxygen can be mixed by the rotating blades 17, and a toggle plate 20 for reciprocating linear motion is also provided to optimize the mixing effect. Figure 5-Figure 9 As shown:

[0060] The end of the connecting shaft 15 is fixedly connected to a second bevel gear 16 meshing with the first bevel gear 13, and the second bevel gear 16 is symmetrically distributed about the center of the first bevel gear 13, the surface of the connecting shaft 15 is fixedly connected to a connecting plate 18, and the surface of the connecting plate 18 is fixedly connected to a first magnet 22, and the first magnet 22 is distributed at equal angles on the surface of the connecting plate 18, a column 24 is fixedly connected to the inner wall of the outer shell 1, and the surface of the column 24 is sleeved with a toggle plate 20, and the surface of the toggle plate 20 is provided with an air vent 21, the connecting shaft 15 is rotatably arranged inside the toggle plate 20, and the connecting shaft 15 does not contact the toggle plate 20.

[0061] A second magnet 26 corresponding to the first magnet 22 is fixedly connected to the surface of the toggle plate 20, and the magnetic poles corresponding to the first magnet 22 and the second magnet 26 are the same. A connecting spring 23 that plays an elastic reset role is fixedly connected to the surface of the toggle plate 20, and the other side of the connecting spring 23 is fixedly connected to the surface of the fixed plate 19.

[0062] When the housing 1 is working, the motor 4 is started, and the motor 4 drives the connecting shaft 15 to rotate inside the auxiliary plate 14 through the first bevel gear 13 and the second bevel gear 16. When the connecting shaft 15 rotates, it drives the rotating blades 17 to rotate synchronously. At this time, the rotating blades 17 play a role in mixing fuel and oxygen, which is convenient for the full combustion of fuel and oxygen. During the rotation of the connecting shaft 15, the connecting plate 18 is driven to rotate synchronously. When the connecting plate 18 rotates, it drives the first magnet 22 to intermittently approach the second magnet 26 on the surface of the toggle plate 20. When the first magnet 22 approaches the second magnet 26, the toggle plate 20 moves under the action of the mutually repelling magnetic force. The toggle plate 20 moves in the direction of squeezing the connecting spring 23 (the toggle plate 20 cooperates with the fixed plate 19 to compress the connecting spring 23). When the first magnet 22 moves away from the second magnet 26, the toggle plate 20 returns to its original position under the action of the connecting spring 23, and the above process is repeated. Under the action of the mutually repulsive magnetic force, the connecting spring 23 and the column 24, the toggle plate 20 makes reciprocating linear motion in the vertical direction. At this time, the toggle plate 20 also plays a role in disturbing the airflow, which is convenient for mixing fuel and oxygen. On the surface of the toggle plate 20, air holes 21 are evenly spaced to make it easier for the airflow to pass through, so that the airflow will not flow smoothly.

[0063] Embodiment 3: Different from Embodiment 2, the side plate 25 and the knocking block 27 are provided to hit the outer wall of the discharge pipe 12, so that the discharge pipe 12 can discharge gas better, and thus no impurities remain inside the discharge pipe 12, such as Fig. 9 Said:

[0064] A side plate 25 is fixedly connected to the side of the upper toggle plate 20 , and a knocking block 27 corresponding to the discharge pipe 12 is fixedly connected to the upper surface of the side plate 25 , and the knocking blocks 27 are evenly spaced on the upper surface of the side plate 25 .

[0065] During operation, the discharge pipe 12 is closed. At this time, the fuel and oxygen are mixed and discharged through the discharge pipe 3. When impurities need to be removed, the discharge pipe 3 is closed and the discharge pipe 12 is opened. At this time, the smoke is discharged from the discharge pipe 12. When the toggle plate 20 at the upper end moves, it will drive the side plate 25 and the knocking block 27 to move synchronously. When the knocking block 27 moves, it will intermittently hit the outer wall of the discharge pipe 12, so that the discharge pipe 12 is in a state of intermittent vibration, so that fewer impurities remain inside the discharge pipe 12.

[0066] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
