Description

Technical Field

[0001] The present invention relates to a baking furnace structure, and in particular to a baking furnace with a turnover function for uniform baking. Background Art

[0002] In many industrial applications, titanium substrates have characteristics such as light weight and corrosion resistance, and are often used as the base materials of electrode plates, which are widely used in the chlor-alkali industry and wastewater treatment. In the processing of electrode plates, in order to further improve the electrochemical performance of the substrates, it is usually necessary to perform a coating treatment on their surfaces to increase the corrosion resistance or improve the electrical conductivity; based on this, our research on coating found that the actual coating process is generally to first coat a solution of iridium chloride on the surface of the titanium substrate, and then transfer the coated electrode plate to a baking furnace for baking. During the baking process, iridium chloride will turn into iridium dioxide under air conditions. However, because the existing baking furnace needs to consider that the surface of the coating cannot be subjected to clamping pressure, the electrode plate is usually placed statically in the furnace for heating. This traditional static baking method is very likely to cause uneven baking. Even in the prior art, by adopting a method of driving the internal hot air flow of the furnace to circulate, so that the hot air flow heated by the heater can be timely diffused to all corners of the furnace body to improve the uniformity of the internal air flow temperature, but also because in actual operation, it is very difficult for people to accurately control the direction of the air flow in the furnace so that the heat can evenly and averagely contact the surface of the electrode plate, so that its baking uniformity is still difficult to meet the higher requirements of people. Summary of the Invention

[0003] In order to solve the above technical problems, the object of the present invention is to provide a baking furnace with a turnover function for uniform baking. By setting the baking furnace body as a column shape, and the electric heating tubes are axially arranged in the furnace wall of the baking furnace body. Therefore, when the baking furnace body is driven by a driving part one to perform a 360° circumferential uniform turnover, the electric heating tubes can also perform a 360° turnover around the electrode plate. At this time, each point on the plate surface will periodically pass through the heat source position for radiation, and the average values of the heat input time and distance will tend to be the same, similar to the "integration effect", so that the heat source can evenly radiate to the coating surface to the greatest extent, so as to ensure the uniformity of the coating baking on the electrode plate to the greatest extent.

[0004] The present invention provides the following technical solutions:

[0005] A baking oven with a flipping function for uniform baking, comprising a group of cylindrical baking oven bodies supported on a base. Electric heating tubes extending axially are also provided on the cylindrical inner walls of the baking oven bodies. The electric heating tubes are arranged as a group or multiple groups arranged side by side circumferentially along the inner wall of the baking oven body. And when the electric heating tubes are arranged as multiple groups, the maximum included angle of the arc surface occupied by the multiple groups of electric heating tubes is less than 90°. Therefore, when the baking oven body is driven by a first driving part to perform a 360° circumferential uniform flip, the electric heating tubes can also perform a 360° flip around the electrode plate, so as to ensure the uniformity of the coating baking on the electrode plate. At the same time, due to the limitation on the number of electric heating tubes arranged side by side, that is, the included angle of the arc surface formed between the two outermost electric heating tubes after being arranged side by side is less than 90°. Therefore, it can avoid the phenomenon of local overheating caused by the continuous heat radiation on one side. A first driving part for driving the baking oven body to rotate uniformly around its axis is installed on the base. One end of the baking oven body in the axial direction is provided with a cover, and the cover is pushed by a push cylinder to be pressed against the end of the baking oven body for sealing. The push cylinder is installed on the side wall of the baking oven body. A group of first supporting members are rotatably installed on the cover. The first supporting members are used to position and support the electrode plate to be dried and move with the cover to extend the electrode plate into the center of the baking oven body. A group of second supporting members are also provided on the opposite side of the first supporting members. The second supporting members are rotatably installed at the other end of the baking oven body in the axial direction and are used for plug-in installation with the end side of the first supporting members extending into the baking oven body, so as to support the electrode plate below in combination with the first supporting members and improve the stability of the support. At this time, during the baking operation, when the baking oven body is driven by the first driving part to perform a 360° flip, the electrode plate is statically placed on the first supporting members, and its center is also at the center of the baking oven body. At this time, it can be regarded as the baking oven body driving the electric heating tubes to perform a 360° uniform flip heating around the electrode plate. At this time, each point on the plate surface will periodically pass through the heat source position for radiation, and the average values of the heat input time and distance will tend to be the same, similar to the "integration effect", so that the heat source can radiate uniformly to the coating surface to the greatest extent, so as to ensure the uniformity of the coating baking on the electrode plate to the greatest extent.

[0006] Preferably, a group of first supporting platforms are slidably installed on the base. The first supporting members include a cylindrical outer member one for fixedly supporting on the first supporting platform. The cylindrical outer member one is rotatably installed in the cover. A group of horizontal supporting platforms are fixed at one end of the cylindrical outer member one facing the baking oven body to horizontally support the electrode plate to be dried. A group of second supporting platforms are also fixedly installed on the base. The second supporting members include a cylindrical outer member two for fixedly supporting on the second supporting platform. The cylindrical outer member two is rotatably installed at the end of the baking oven body. A group of horizontal insertion plates are fixed at one end of the cylindrical outer member two facing the baking oven body to be inserted and installed at the end of the horizontal supporting platform, so as to support the electrode plate below in combination with the first supporting members and improve the stability of the support.

[0007] Preferably, the middle parts of the cylindrical outer part 1 and the cylindrical outer part 2 are both provided with a connecting port for connecting the inside and outside of the baking oven body, the connecting port is controlled to open and close by an electromagnetic valve, and the connecting port at one end is set as an air inlet, and the connecting port at the other end is set as an air outlet. A group of mounting cavities are also provided in the cylindrical outer part 1, the mounting cavity is open at one end facing the baking oven body, and connected to the connecting port at the end away from the baking oven body, and a driving part 2 for driving the electrode plate to rotate horizontally is installed in the mounting cavity. At this time, in order to be able to remove the moisture from baking in time, an air inlet and an air outlet are also provided. Since the air inlet and the air outlet are set on opposite sides, the air inlet and the air outlet will trigger the flow of hot air flow, affecting the uniformity of baking. At this time, in order to avoid the influence of the air flow direction on the axial temperature, a driving part 2 is added that can drive the electrode plate to rotate horizontally circumferentially in the baking oven body. At this time, the rotation of the electrode plate can reduce the influence of the temperature difference at both ends caused by the guided airflow on the two ends of the electrode plate.

[0008] Preferably, the second driving part is connected to a driving wheel installed in the installation cavity and a driving motor installed outside the cylindrical outer part. A group of circular horizontal plates are also connected to the horizontal support platform. The horizontal plates are circumferentially provided with an outer gear ring that meshes with the driving wheel. The horizontal plates are used to position and support the electrode plates. At this time, because the driving motor is arranged on the outside, it realizes the rotation of the electrode plate by driving the driving wheel located in the furnace body, thereby reducing the impact of high temperature on the driving motor during baking.

[0009] Preferably, in order to more conveniently realize the loading and unloading of the electrode plate, the horizontal support platform is provided to include a horizontal fixed platform and a group of slides, the top surface of the slide is used for transfer installation with the horizontal plate, the horizontal fixed platform is provided with a group of slots opening toward one side, the slide slides from the opening of the slot to the horizontal fixed platform, and is limited by the limit block at the end of the slot when sliding into the slot, the limit block is slidably installed on the horizontal fixed platform, when the slide needs to be slid out, the limit block can be slid to both sides, at this time, the end limit of the slide can be cancelled Position, the slide can slide out from the opening of the slot. At this point, when it is necessary to unload the electrode plate, the push cylinder can push the electrode plate out of the baking furnace body, and then slide out the slide with the electrode plate. When loading is required, the electrode plates are first placed on the slide in batches, and the slide is driven by a conveyor to move to one side of the horizontal fixed table, and then the slide is pushed to the horizontal fixed table by the ejection cylinder. At this time, there is no need to lift and take out the baked electrode plate in the area close to the furnace body. The sliding method is faster than lifting and taking it away, and it also shortens the time for intermediate transitions.

[0010] Preferably, the surface of the horizontal plate is designed with a hollow-out structure, and a positioning groove for inserting the positioning plate is further formed on its top surface. The positioning plate is used to limit the periphery of the electrode plate, so as to limit the electrode plate circumferentially. By inserting the positioning plate into the positioning grooves at different positions, the center positioning of electrode plates with different sizes can be adapted.

[0011] Preferably, the first driving part includes a set of rotating wheels mounted on the base platform and a rotating motor drivingly connected to the rotating shaft at one end of the rotating wheel. The rotating wheel meshes with the toothed ring part arranged outside the baking furnace body.

[0012] Preferably, a guide post parallel to the axis is further arranged at one end of the baking furnace body. The cover is guidingly installed outside the guide post, so that when the cover moves away from the baking furnace body, it can move under the guidance of the guide post, thereby improving the stability of the movement.

[0013] Preferably, a slide rail for slidably connecting with the support platform is further arranged on the base platform.

[0014] Preferably, when the electric heating tube is located above the electrode plate coating to radiate heat towards the front of the electrode plate coating, the electrode plate is static at the original position in the center of the baking furnace body. When moisture needs to be removed from the baking furnace body, when the electric heating tube rotates from the front of the electrode plate coating to the back of the electrode plate coating, the air inlet and the air outlet are opened, and at the same time, the second driving part is started to drive the electrode plate to rotate. After the electrode plate rotates at least one week, the electric heating tube returns from the back of the electrode plate coating to the front of the electrode plate coating, and at the same time, the air inlet and the air outlet are closed, and the electrode plate also returns to the original position in the center of the baking furnace body. Thus, the influence on the baking uniformity during moisture removal can be reduced as much as possible.

[0015] The beneficial effects of the present invention are as follows:

[0016] In the present invention, by setting the baking furnace body as a columnar shape and arranging the electric heating tubes axially in the furnace wall of the baking furnace body, therefore, when the baking furnace body is driven by the first driving part to perform a 360° circumferential uniform rotation, the electric heating tubes can also rotate 360° around the electrode plate accordingly. At this time, each point on the plate surface will periodically pass through the heat source position for radiation, and the average values of the heat input time and distance will tend to be the same, similar to the "integration effect", so that the heat source can radiate uniformly to the coating surface to the greatest extent, thereby ensuring the baking uniformity of the coating on the electrode plate to the greatest extent. (Because the baking uniformity is affected by the heat source spacing, quantity, baking time, and the shape, color, conduction material, and air flow of the object to be baked, etc., therefore, what we can do is to maximize the realization of the uniform radiation of baking);

[0017] Moreover, in order to timely remove the water vapor generated during baking, an air inlet and an air outlet are provided. Since the air inlet and the air outlet are arranged on opposite sides, the intake and exhaust of air will cause the flow of hot air. At this time, in order to avoid the influence of the air flow direction on the axial temperature, a second driving part is added to drive the electrode plate to rotate circumferentially within the baking furnace body, so as to reduce the influence of the temperature difference at both ends caused by the air flow on both ends of the electrode plate;

[0018] During the baking process of the present invention, the operations from loading, baking to unloading can be automated, thereby greatly improving the convenience of baking. Brief Description of the Drawings

[0027] Embodiment 1

[0028] As Figures 1-5As shown, a baking oven with a flipping function for uniform baking, in this embodiment, comprises a group of cylindrical baking oven bodies 2 supported on a base 1, and an electric heating tube 3 extending in the axial direction is further provided on the cylindrical inner wall of the baking oven body 2, and the electric heating tube 3 is provided in a group or in multiple groups arranged side by side along the circumferential direction of the inner wall of the baking oven body 2, and when the electric heating tube 3 is provided in multiple groups, the maximum angle of the arc surface occupied by the electric heating tube 3 provided in the multiple groups is less than 90 degrees, so when the baking oven body 2 is driven by the driving part 4 to perform a 360 degree circumferential uniform flip, the electric heating tube 3 can also be rotated along the circumferential direction. It is turned 360 degrees around the electrode plate 10 to ensure the uniformity of the coating baking on the electrode plate 10. At the same time, the number of electric heating tubes 3 arranged side by side is limited, that is, the arc angle formed between the electric heating tubes 3 at the two ends after being arranged side by side is less than 90 degrees. Therefore, it can avoid the local overheating caused by the constant heat radiation on one side. A driving part 4 for driving the baking furnace body 2 to rotate uniformly around its axis is installed on the base 1. A sealing cover 5 is provided at one axial end of the baking furnace body 2. The sealing cover 5 is pushed by the push cylinder 7 to press the end of the baking furnace body 2 to seal it. , the push cylinder 7 is installed on the side wall of the baking furnace body 2, and a group of support members 8 are installed on the cover 5. The support members 8 are used to position and support the electrode plate 10 to be dried, and move with the cover 5 to extend the electrode plate 10 into the center of the baking furnace body 2. A group of support members 2 9 are also provided on the opposite side of the support member 8. The support member 2 9 is installed on the other end of the baking furnace body 2 in the axial direction, and is used to be plugged into the end side of the support member 8 extending into the baking furnace body 2, so as to be combined with the support member 8 to support the bottom of the electrode plate 10, thereby improving the stability of the support. At this time, during the baking operation, When the baking furnace body 2 is driven by the driving part 4 to flip 360°, the electrode plate 10 is stationary on the support 8, and its center is also at the center of the baking furnace body 2. At this time, it can be regarded as the baking furnace body 2 driving the electric heating tube 3 to perform 360° uniform flip heating around the electrode plate 10. At this time, each point on the plate surface will periodically radiate through the heat source position, and the average time and distance of the heat input will tend to be consistent, similar to the "integral effect", so that the heat source can be radiated to the coating surface as evenly as possible, thereby ensuring the uniformity of the coating baking on the electrode plate 10 to the greatest extent.

[0029] A group of supports 11 are also slidably installed on the base 1, and the support member 8 includes a cylindrical outer member 81 for fixedly supporting on the support member 11, and the cylindrical outer member 81 is installed in the cover 5. A group of horizontal supports 82 are fixed on the end of the cylindrical outer member 81 facing the baking furnace body 2 to horizontally support the electrode plate 10 to be dried. A group of supports 12 are also fixed on the base 1, and the support member 2 9 includes a cylindrical outer member 91 for fixedly supporting on the support member 12, and the cylindrical outer member 91 is installed in the end of the baking furnace body 2. A group of horizontal plug-in plates 92 are fixed on the end of the cylindrical outer member 91 facing the baking furnace body 2 to be plugged into the end of the horizontal support member 82, so as to be combined with the support member 8 to support under the electrode plate 10, thereby improving the stability of the support.

[0030] Example 2

[0031] A baking oven with a flipping function for uniform baking, in this embodiment, is further defined based on embodiment 1, wherein the middle parts of the cylindrical outer member 1 81 and the cylindrical outer member 2 91 are both provided with a connecting port for connecting the inside and outside of the baking oven body 2, the connecting port is controlled to open and close by a solenoid valve, and the connecting port at one end is set as an air inlet 13, and the connecting port at the other end is set as an air outlet 14, and a group of mounting cavities 83 are further provided in the cylindrical outer member 1 81, the mounting cavity 83 is opened at one end toward the baking oven body 2, and is connected to the connecting port at the end away from the baking oven body 2, and the mounting cavity 83 is installed The driving part 2 is used to drive the electrode plate 10 to rotate horizontally. At this time, in order to be able to remove the water vapor during baking in time, an air inlet 13 and an air outlet 14 are also set. Since the air inlet 13 and the air outlet 14 are set on opposite sides, the air inlet and outlet will trigger the flow of hot air flow, affecting the uniformity of baking. At this time, in order to avoid the influence of the air flow direction on the axial temperature, a driving part 2 is added to drive the electrode plate 10 to rotate horizontally in the baking furnace body 2. At this time, the rotation of the electrode plate 10 can reduce the influence of the temperature difference at both ends caused by the guided airflow on the two ends of the electrode plate 10.

[0032] The second driving part is connected to the driving wheel 84 installed in the installation cavity 83 and the driving motor installed outside the cylindrical outer part 81. A group of circular horizontal plates 85 are also connected to the horizontal support platform 82. The horizontal plate 85 is circumferentially provided with an outer gear ring 86 that meshes with the driving wheel 84. The horizontal plate 85 is used to position and support the electrode plate 10. At this time, because the driving motor is arranged on the outside, it realizes the rotation of the electrode plate 10 by driving the driving wheel 84 located in the furnace body, thereby reducing the impact of high temperature on the driving motor during baking.

[0033] In order to more conveniently realize the loading and unloading of the electrode plate 10, a horizontal support platform 82 is provided, including a horizontal fixed platform 821 and a set of slides 822. The top surface of the slide 822 is used for connecting and installing with the horizontal plate 85. A set of slots 823 opening toward one side are provided on the horizontal fixed platform 821. The slide 822 slides from the opening of the slot 823 to the horizontal fixed platform 821, and is limited by the limit block 824 at the end of the slot 823 when sliding into the slot 823. The limit block 824 is slidably installed on the horizontal fixed platform 821. When the slide 822 needs to be slid out, the limit block 824 can be slid to both sides. At this time, the end of the slide 822 can be cancelled. The slide 822 can slide out from the opening of the slot 823. At this point, when it is necessary to unload the electrode plate 10, the push cylinder 7 can push the electrode plate 10 out of the baking furnace body 2, and then slide out the slide 822 with the electrode plate 10. When loading is required, the electrode plates 10 are first placed in batches on the slide 822, and the slide 822 is driven by a conveyor to move to one side of the horizontal fixed table 821, and then the slide 822 is pushed onto the horizontal fixed table 821 by the ejection cylinder. At this time, there is no need to lift and remove the baked electrode plate 10 in the area close to the furnace body. Sliding removal is faster than lifting removal, and the intermediate transition time is also shortened.

[0034] The surface of the horizontal plate 85 is hollowed out, and a positioning groove for inserting the positioning plate 87 is provided on its top surface. The positioning plate 87 is used to limit the periphery of the electrode plate 10, so as to limit the circumferential position of the electrode plate 10. By providing positioning grooves at different positions to insert the positioning plate 87, the center positioning of electrode plates 10 of different sizes can be adapted.

[0035] The driving part 1 4 includes a set of rotating wheels 41 mounted on the base 1 and a rotating motor 42 drivingly connected to a rotating shaft at one end of the rotating wheel 41 . The rotating wheel 41 is engaged with a gear ring 43 externally arranged outside the baking oven body 2 .

[0036] One end of the baking oven body 2 is also provided with a guide column 6 parallel to the axial direction, and the cover 5 is guided and installed outside the guide column 6 so that the cover 5 can move under the guidance of the guide column 6 when it is away from the baking oven body 2, thereby improving the stability of the movement.

[0037] The base 1 is further provided with a slide rail 15 which is slidably mounted on the support.

[0038] When the electric heating tube 3 is located above the coating of the electrode plate 10 to radiate heat towards the front of the coating of the electrode plate 10, the electrode plate 10 is static at the original position in the center of the baking furnace body 2. When it is necessary to dehumidify the baking furnace body 2, when the electric heating tube 3 rotates from the front of the coating of the electrode plate 10 to the back of the coating of the electrode plate 10, the air inlet 13 and the air outlet 14 are opened, and at the same time, the driving part two is started to drive the electrode plate 10 to rotate. After the electrode plate 10 rotates at least one week, the electric heating tube 3 returns from the back of the coating of the electrode plate 10 to the front of the coating of the electrode plate 10, and at the same time, the air inlet 13 and the air outlet 14 are closed, and the electrode plate 10 also returns to the original position in the center of the baking furnace body 2. Thus, the influence on the baking uniformity during dehumidification can be reduced as much as possible.

[0039] The working principle of the present invention is as follows: in the present invention, the electrode plates 10 can be batchwise placed on the sliding tables 822 in one-to-one correspondence. When feeding is required, the sliding tables 822 can be driven by the conveyor to move to one side of the horizontal fixed table 821, and then the sliding tables 822 can be pushed onto the horizontal fixed table 821 by the ejector cylinder on one side of the conveyor. Then, the push cylinder 7 is started to drive the electrode plate 10 into the baking furnace body 2 through the sealing cover 5 and the support member one 8. After the sealing cover 5 seals the baking furnace body 2, the driving member can be started to make the baking furnace body 2 rotate around the electrode plate 10 for baking. When it is necessary to dehumidify the baking furnace body 2, when the electric heating tube 3 rotates from the front of the coating of the electrode plate 10 to the back of the coating of the electrode plate 10, the air inlet 13 and the air outlet 14 are opened, and at the same time, the driving part two is started to drive the electrode plate 10 to rotate. After the electrode plate 10 rotates at least one week, the electric heating tube 3 returns from the back of the coating of the electrode plate 10 to the front of the coating of the electrode plate 10, and at the same time, the air inlet 13 and the air outlet 14 are closed, and the electrode plate 10 also returns to the original position in the center of the baking furnace body 2. Thus, the influence on the baking uniformity during dehumidification can be reduced as much as possible. After baking is completed, the push cylinder 7 is started again to push out the sealing cover 5, and then the sliding table 822 is slid onto the conveyor, waiting for the next group of sliding tables 822 to drive the electrode plate 10 to slide in.

Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
