Abstract
Description
Technical Field
[0001] This utility model relates to the field of pre-baked anode technology, and in particular to a dewatering device for a green anode carbon bowl. Background Technology
[0002] The production of prebaked anodes for aluminum consists of three main processes: petroleum coke calcination, green anode manufacturing, and anode baking. Green anode manufacturing, with its numerous locations and wide distribution, is the core process in these factories. During green anode manufacturing, the mixture of calcined petroleum coke and high-temperature pitch is vibrated and shaped to a temperature of approximately 130°C. To prevent deformation or cracking, the green anodes must be promptly immersed in a water tank at approximately 30°C for 40–60 minutes to cool completely. After cooling, water accumulates in the upper carbon bowl of the green anode, which is unacceptable in the downstream anode baking process. Factories typically use compressed air to blow water into the carbon bowl to remove this water.
[0003] Using compressed air to purge water from the green anode carbon cup results in high noise levels (volume greater than 120dB) and high compressed air consumption (compressed air volume greater than 5m³ / s). 3 The high energy consumption ( / h) and the high-speed splashing of water droplets during purging can easily damage electrical equipment. Utility Model Content
[0004] In view of this, the present invention provides a water removal device for a green anode carbon bowl, the main purpose of which is to remove water from the carbon bowl in a low-noise manner and reduce the consumption of compressed air.
[0005] To achieve the above objectives, this utility model mainly provides the following technical solutions:
[0006] This utility model provides a dewatering device for a green anode carbon bowl, which includes: a frame, a lifting mechanism and a dewatering mechanism;
[0007] The frame spans the green anode carbon block conveying working surface. A first transmitting component is installed on one side of the frame, and a first receiving component is installed on the other side of the frame. The first transmitting component and the first receiving component are arranged opposite to each other for monitoring the conveyed green anode carbon block.
[0008] The lifting mechanism includes a crossbeam and two telescopic components. The upper ends of the two telescopic components are respectively connected to the frame, the lower end of one telescopic component is connected to one end of the crossbeam, and the lower end of the other telescopic component is connected to the other end of the crossbeam.
[0009] The dewatering mechanism includes multiple sponge blocks, which are arranged axially in sequence on the crossbeam. Each sponge block corresponds to one of the carbon bowls on the upper surface of the green anode carbon block.
[0010] The first receiving component is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the telescopic component.
[0011] The purpose of this utility model and the technical problems to be solved can be further achieved by the following technical measures.
[0012] Optionally, it also includes two through frames, each of which is fixedly connected to the lower end of one of the telescopic components. The two ends of the crossbeam pass through the through frames respectively. The lower side wall of the crossbeam is fixedly connected to the upper ends of two limiting rods. The two limiting rods are set on opposite sides of the green anode carbon block conveying working surface. The side of the limiting rod facing the green anode carbon block is connected to the first roller.
[0013] Optionally, each of the through frames has a second roller on its top wall and a third roller on its bottom wall, with the crossbeam positioned between the second roller and the third roller.
[0014] Optionally, it also includes two limiting plates, which are respectively fixedly connected to opposite ends of the crossbeam.
[0015] Optionally, it also includes a second transmitting component and a second receiving component. The upper end of the telescopic component is hinged to the frame. The second transmitting component is fixedly installed in the middle of the telescopic component. The second receiving component is fixedly installed in the frame. The second receiving component corresponds to the high point position of the second transmitting component as it swings along the telescopic component. The second receiving component is electrically connected to the input terminal of the controller.
[0016] Optionally, it also includes a limiting plate, the upper end of which is fixedly connected to the frame. The limiting plate extends vertically, and the telescopic component in the vertical state abuts against the limiting plate.
[0017] Optionally, it also includes an electric heating tape, wherein the crossbeam is provided with a plurality of radial through grooves in sequence along the axial direction, the middle part of the sponge block is embedded in the radial through grooves, and the electric heating tape is wrapped around the upper side of the sponge block.
[0018] By employing the above technical solution, this utility model has at least the following advantages:
[0019] When the green anode carbon block reaches the bottom of the frame along with the conveying working surface, the photoelectric signal emitted by the first transmitting component is blocked by the green anode carbon block and cannot be received by the first receiving component. This triggers the first receiving component to send a first electrical signal to the controller. The controller controls the telescopic component to extend, and the telescopic component drives the crossbeam to move downward, thereby causing the sponge block to contact the water in the carbon bowl, achieving the purpose of the sponge absorbing the water.
[0020] When the green anode carbon block moves forward with the conveyor belt and no longer blocks the first transmitting component from transmitting photoelectric signals to the first receiving component, it triggers the first receiving component to send a second electrical signal to the controller. The controller controls the telescopic component to retract, and the telescopic component drives the crossbeam to move upward, thereby moving the sponge away from the green anode carbon block.
[0021] As the green anode carbon blocks are continuously conveyed from the conveying working face, this device repeats the above process to remove moisture from the carbon bowl.
[0022] In the above process, there is no noise generated when compressed air is ejected, but there is also a consumption of compressed air. Attached Figure Description

Detailed Implementation
[0026] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.
[0028] like Figure 1 As shown, an embodiment of the present invention provides a dewatering device for a green anode carbon bowl, which includes: a frame 1, a lifting mechanism and a dewatering mechanism;
[0029] The frame 1 spans the conveying working surface 2 of the green anode carbon block 5. A first transmitting component 3 is installed on one side of the frame 1, and a first receiving component 4 is installed on the other side of the frame 1. The first transmitting component 3 and the first receiving component 4 are arranged opposite to each other to monitor the conveyed green anode carbon block 5.
[0030] The lifting mechanism includes a crossbeam 6 and two telescopic components 7. The upper ends of the two telescopic components 7 are respectively connected to the frame 1, the lower end of one telescopic component 7 is connected to one end of the crossbeam 6, and the lower end of the other telescopic component 7 is connected to the other end of the crossbeam 6.
[0031] The dewatering mechanism includes multiple sponge blocks 8, which are arranged axially in sequence on the crossbeam 6. Each sponge block 8 corresponds to one of the carbon bowls on the upper surface of the green anode carbon block 5.
[0032] The first receiving component 4 is electrically connected to the input terminal of the controller, and the output terminal of the controller is electrically connected to the telescopic component 7.
[0033] The working process of the raw anode carbon bowl dewatering device is as follows:
[0034] When the raw anode carbon block 5 arrives below the frame 1 along with the conveying working surface 2, the photoelectric signal emitted by the first transmitting component 3 is blocked by the raw anode carbon block 5 and cannot be received by the first receiving component 4. This triggers the first receiving component 4 to send a first electrical signal to the controller. The controller controls the telescopic component 7 to extend, and the telescopic component 7 drives the crossbeam 6 to move downward, thereby causing the sponge block 8 to contact the water in the carbon bowl 9, achieving the purpose of the sponge absorbing the water.
[0035] When the green anode carbon block 5 moves forward with the conveyor belt and no longer blocks the first transmitting component 3 from transmitting photoelectric signals to the first receiving component 4, the first receiving component 4 is triggered to send a second electrical signal to the controller. The controller controls the telescopic component 7 to retract, and the telescopic component 7 drives the crossbeam 6 to move upward, thereby moving the sponge away from the green anode carbon block 5.
[0036] As the conveying working face 2 continuously conveys the green anode carbon block 5, the device repeats the above process to remove moisture from the carbon bowl 9.
[0037] In the above process, there is no noise generated when compressed air is ejected, but there is also a consumption of compressed air.
[0038] Specifically, the first transmitting component 3 is an infrared transmitter, and the first receiving component 4 is an infrared receiver.
[0039] Specifically, the conveying working surface 2 is the conveying working surface 2 of the chain conveyor, and the frame 1 spans the width direction of the conveying working surface 2.
[0040] Specifically, the telescopic component 7 is a pneumatic cylinder or a hydraulic cylinder, the cylinder body of the pneumatic cylinder or hydraulic cylinder is connected to the frame 1, and the piston rod of the pneumatic cylinder or hydraulic cylinder is connected to the crossbeam 6.
[0041] The output of the controller is connected to the electromagnetic coil of the electromagnetic two-position valve that controls the cylinder or hydraulic cylinder pipeline. The extension and retraction of the telescopic component 7 are controlled by controlling the valve position of the electromagnetic two-position valve.
[0042] like Figure 1 and Figure 2 As shown, in a specific embodiment, it also includes two through frames 10. Each through frame 10 is fixedly connected to the lower end of one of the telescopic components 7. The two ends of the crossbeam 6 pass through the through frames 10 respectively. The lower side wall of the crossbeam 6 is fixedly connected to the upper ends of two limiting rods 11. The two limiting rods 11 are set on opposite sides of the conveying working surface 2 of the green anode carbon block 5. The side of the limiting rod 11 facing the green anode carbon block 5 is connected to the first roller 12.
[0043] In this embodiment, specifically, the top wall of the through frame 10 is fixedly connected to the lower end of the telescopic component 7, and the two ends of the crossbeam 6 are slidably connected to the through frame 10 respectively. The distance between the first rollers 12 on the two limiting rods 11 is slightly larger than the width of the green anode carbon block 5.
[0044] When the telescopic component 7 moves the crossbeam 6 downward, the two limiting rods 11 move downward along the opposite sides of the green anode carbon block 5, and the first roller 12 rolls downward along the opposite sides of the green anode carbon block 5. If there is a slight misalignment between the horizontal relative positions of the sponge block 8 and the carbon bowl on the crossbeam 6 at the initial position, the limiting rods 11 and the first roller 12 can be used to correct the misalignment in time, so that the sponge block 8 and the carbon bowl correspond one-to-one.
[0045] like Figure 1 and Figure 2 As shown, in a specific embodiment, the top wall of each through frame 10 is provided with a second roller 13, the bottom wall of the through frame 10 is provided with a third roller 14, and the crossbeam 6 is disposed between the second roller 13 and the third roller 14.
[0046] Without the second roller 13 and the third roller 14, the sliding friction between the crossbeam 6 and the inner surface of the through frame 10 would result in a large coefficient of friction. When the telescopic component 7 drives the crossbeam 6 to move downwards, and the first roller 12 contacts the upper side of the green anode carbon block 5 and rolls downwards, the horizontal relative position of the crossbeam 6 and the through frame 10 is not easily changed in time. As a result, the stress between the crossbeam 6 and the limiting rod 11 is very large. After long-term operation, the first roller 12 and the limiting rod 11 are prone to damage.
[0047] However, in this embodiment, a third roller 14 and a second roller 13 are provided. The crossbeam 6 is subjected to rolling friction, and the coefficient of friction is small. The horizontal position of the crossbeam 6 can change in a timely manner, and the limiting rod 11 and the first roller 12 can be used for a longer time.
[0048] like Figure 1 As shown, in a specific embodiment, it also includes two limiting plates 15, which are respectively fixedly connected to the opposite ends of the crossbeam 6.
[0049] In this embodiment, since the second roller 13 and the third roller 14 are provided in the through frame 10, the friction coefficient of the horizontal movement of the crossbeam 6 is small. In order to prevent the horizontal movement of the crossbeam 6 from being too flexible and detaching from the through frame 10, a limiting plate 15 is installed at the opposite ends of the crossbeam 6. The size of the limiting plate 15 is larger than the inner edge size of the through frame 10, so that both ends of the crossbeam 6 are always located within the through frame 10.
[0050] like Figure 1 and Figure 2 As shown, in a specific embodiment, it also includes a second transmitting component 16 and a second receiving component 17. The upper end of the telescopic component 7 is hinged to the frame 1. The second transmitting component 16 is fixedly installed in the middle of the telescopic component 7. The second receiving component 17 is fixedly installed in the frame 1. The second receiving component 17 corresponds to the high point position of the swing trajectory of the second transmitting component 16 with the telescopic component 7. The second receiving component 17 is electrically connected to the input terminal of the controller.
[0051] In this embodiment, when the telescopic component 7 moves the crossbeam 6 downward to the lowest point of the crossbeam 6's movement trajectory, the sponge is flattened and fully embedded in the carbon bowl 9. At the same time, the green anode carbon block 5 moves forward with the conveying working surface 2. At this time, the crossbeam 6 at the lower end of the telescopic component 7 inevitably moves forward a small distance with the green anode carbon block 5. The telescopic component 7 then swings upward a certain amplitude with the upper hinge point as the center. When the telescopic component 7 swings upward to the maximum angle, the second transmitting component 16 reaches the high point position. The second receiving component 17 corresponds to the second transmitting component 16, thereby triggering the second receiving component 17 to send a second electrical signal to the controller. The controller controls the telescopic component 7 to retract, causing the sponge block 8 to detach from the carbon bowl. The telescopic component 7 and the crossbeam 6 lose the traction force for forward swinging, and the telescopic component 7 swings in the opposite direction. The length of the telescopic component 7 also retracts to the initial length.
[0052] Specifically, the second transmitting component 16 is an infrared transmitter, and the second receiving component 17 is an infrared receiver.
[0053] In this embodiment, instead of the first receiving component 4 sending an electrical signal to the controller, the second receiving component 7 sends an electrical signal to the controller to control the retraction component 7 to retract. This eliminates the need for the green anode carbon block to be completely removed from the signal transmission area of the first transmitting component 3. The timing of the retraction of the retraction component 7 is more timely, allowing for better connection to the water absorption work of the next green anode carbon block carbon bowl.
[0054] like Figure 2 As shown, in a specific embodiment, a limiting plate 18 is also included. The upper end of the limiting plate 18 is fixedly connected to the frame 1. The limiting plate 18 extends in the vertical direction, and the telescopic component 7 in the vertical state abuts against the limiting plate 18.
[0055] In this embodiment, specifically, when the telescopic component 7 swings in the opposite direction and abuts against the limiting plate 18, the telescopic component 7 returns to the vertical position and abuts against the limiting plate 18, consuming the kinetic energy of the telescopic component 7 and preventing the telescopic component 7 from swinging back and forth, thus preparing the sponge block 8 to absorb the carbon bowl water of the next green anode carbon block 5.
[0056] Specifically, it also includes a mounting plate 19, one end of which is fixedly connected to the middle of the limiting plate 18, and the other end extends in the swing direction of the telescopic member 7 (the conveying direction of the working surface). The second receiving member 17 is fixed to the other end of the mounting plate 19, so that the second transmitting member 16 and the second receiving member 17 are opposite each other during the forward swing of the telescopic member 7.
[0057] Specifically, it also includes a rubber pad 20, which is fixedly connected to the side of the limiting plate 18 to buffer the impact force of the telescopic component 7 swinging in the opposite direction.
[0058] like Figure 1 As shown, in a specific embodiment, it also includes an electric heating tape 21. The crossbeam 6 is provided with a plurality of radial through grooves in sequence along the axis. The middle part of the sponge block 8 is embedded in the radial through grooves, and the electric heating tape 21 is wrapped around the upper side of the sponge block 8.
[0059] In this embodiment, specifically, the radial channel extends vertically, the middle part of the sponge block 8 is adhered to the side wall of the radial channel, the heating tape 21 is wrapped around the upper axial side of the sponge block 8, the lower end of the sponge block 8 absorbs water from the carbon bowl, the upper part of the sponge block 8 is heated by the heating tape 21, the water evaporation rate at the upper end of the sponge block 8 is accelerated, thereby forming a humidity gradient from bottom to top in the sponge block 8, the lower end of the sponge block 8 has high humidity and the upper end has low humidity, thereby causing water to diffuse from the lower end of the sponge block 8 to the upper end, so that the water content at the lower end of the sponge block 8 is always unsaturated, and it continues to absorb water.
[0060] Specifically, the electric heating tape 21 uses a pipe-type antifreeze electric heating tape. The heat it emits causes the water on the upper part of the sponge block 8 to evaporate continuously, thereby causing the water absorbed at the lower end of the sponge block 8 to continue to diffuse upwards, maintaining the water absorption capacity of the lower end of the sponge block 8.
[0061] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
