Description

Technical Field

[0001] This utility model relates to the field of prebaked anode calcination technology, specifically a flexible calcination pipe. Background Technology

[0002] Prebaked anodes are anode products with high mechanical strength, strong oxidation resistance and low resistivity obtained by using petroleum coke, a by-product of petrochemicals, as raw material and coal tar pitch, a by-product of coal chemicals, as binder. They are mixed and molded into a green blank of a certain shape, and then heat-treated to carbonize the binder.

[0003] The baking process of prebaked anodes requires the use of an open-loop baking furnace. For example... Figure 13 As shown, an open-loop roasting furnace generally includes multiple fire channels, each fire channel including multiple temperature zones, which are arranged in order of increasing temperature as preheating zone, low temperature zone, volatilization zone, medium temperature zone, sub-high temperature zone and high temperature zone, and the same temperature zone of each fire channel is aligned.

[0004] A flue is a medium connecting the flue and the fire channel, serving to exhaust combustion gases and provide negative pressure to the fire channel. Traditionally, a flue is a rigid component, consisting of a main pipe and branch pipes, with the branch pipes connecting to the exhaust ports in the preheating zone of each fire channel. However, due to the long-term temperature fluctuations during the roasting process in the kiln, the fire channel can deform, and the flue, affected by this deformation, can also deform or crack, thus impacting its exhaust function. Utility Model Content

[0005] To address the aforementioned issues, this application provides a flexible roasting pipe that can adapt to the deformation of the fire channel without deforming or cracking.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A flexible roasting pipe includes a main pipe, on which a plurality of branch components are provided, each corresponding to a fire channel of a roasting furnace.

[0008] The branch component includes a branch pipe that is slidably connected to the main pipe. The main pipe is provided with a communication hole that corresponds to the branch component. The branch pipe is connected to the internal space of the main pipe through the corresponding communication hole. The axial dimension of the communication hole is larger than the inner diameter of the branch pipe.

[0009] The lower end of the branch pipe is connected to the smoke exhaust port of the corresponding fire channel via a smoke exhaust hose;

[0010] A control valve is installed on the branch pipe.

[0011] Furthermore, the branch pipe includes a first pipe body, the upper end of which is provided with a sliding part with an arc-shaped structure. The axial dimension of the sliding part is greater than or equal to the axial dimension of the connecting hole. The main pipe is provided with guide grooves on both sides of the sliding part. The two ends of the guide part are respectively inserted into the guide grooves and form a sliding fit with the guide grooves.

[0012] Furthermore, the lower end of the exhaust hose is provided with a connector, the connector including a connecting plate, the connecting plate having a through hole allowing smoke to pass through, a first connecting cylinder being provided on the upper side of the connecting plate and connected to the lower end of the exhaust hose, and a second connecting cylinder being provided on the lower side of the connecting plate, the outer side of the second connecting cylinder having a tapered structure, and the outer diameter of the second connecting cylinder gradually decreasing in the direction away from the connecting plate.

[0013] Furthermore, a first adjusting drive is provided between the two connected branch pipes, and one of the branch pipes at the end is connected to the main pipe through a second adjusting drive.

[0014] Furthermore, the main pipeline also includes two support frames for supporting the main pipeline.

[0015] Furthermore, a base plate is provided on the lower side of the support frame, a screw is provided on the base plate, the support frame is provided with mounting holes for accommodating the screw, and locking nuts are respectively provided on the upper and lower sides of the mounting holes on the screw.

[0016] Furthermore, a ladder is installed on the main pipeline.

[0017] Furthermore, the main pipeline is provided with several cleaning ports, and the opening end of each cleaning port is provided with a removable and washable cover plate, and the cover plate is provided with a second lifting lug.

[0018] Furthermore, a first lifting lug is provided on the main pipe.

[0019] Furthermore, the opening degree of the control valve is adjusted according to the temperature fed back by the temperature measuring component of the corresponding fire channel.

[0020] The beneficial effects of this utility model are:

[0021] This application provides a flexible roasting pipe that changes the connection method of the branch pipe, replacing the fixed connection between the branch pipe and the main pipe with a sliding connection. Simultaneously, the branch pipe is connected to the exhaust port of the corresponding fire channel via a flexible exhaust hose. In this way, even if the fire channel deforms during the long-term heating and cooling process, it will not affect the pipe head. The pipe can adapt well to the deformation of the fire channel, ensuring smooth exhaust. Attached Figure Description

[0040] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be described in detail below with reference to the accompanying drawings. The described embodiments are merely a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the protection scope of this application.

[0041] For ease of description, the coordinate system is defined as follows: Figure 1 As shown, the left and right directions are horizontal, the front and back directions are vertical, and the up and down directions are vertical.

[0042] Example 1

[0043] like Figure 1 , Figure 3 , Figure 5 and Figure 13 As shown, a flexible roasting pipe includes a main pipe, which is open at one end and closed at the other end, and the open end of the main pipe is connected to a flue.

[0044] In one specific embodiment, the main pipeline in this example includes a horizontal section 11. A vertical section 12 is provided at one end of the horizontal section 11. The upper end of the vertical section 12 is connected to the horizontal section 11 via an arc-shaped connecting section 13, and the lower end of the vertical section 12 is an open end. A sealing plate 14 is provided at the other end of the horizontal section 11, and the sealing plate 14 is sealed to the horizontal section 11 of the main pipeline via a flange connection.

[0045] The horizontal section 11 of the main pipeline is provided with a number of branch components 2 along the axial direction. The number of branch components 2 is the same as the number of fire channels 5 of the roasting furnace, and they correspond one-to-one.

[0046] like Figure 12 As shown, the branch component 2 includes a branch pipe 21, the upper end of which is slidably connected to the horizontal section 11 of the main pipe. The branch pipe 21 is capable of reciprocating relative to the main pipe along the axial direction. The main pipe is provided with connecting holes 111 corresponding to the branch components 2. The axial dimension of the connecting hole 111 is larger than the inner diameter of the branch pipe 21. The branch pipe 21 communicates with the internal space of the main pipe through the corresponding connecting hole 111, and the connecting hole 111 determines the travel range of the branch pipe 21 reciprocating relative to the main pipe.

[0047] In one specific embodiment, the connecting hole 111 described in this embodiment is an elongated oval hole with its long axis extending axially.

[0048] As one specific implementation method, such as Figure 4 , Figure 6 and Figure 11 As shown, in this embodiment, the branch pipe 21 includes a first pipe body 2111. The upper end of the first pipe body 2111 is provided with a sliding part 2112 with an arc-shaped structure. The axial dimension of the sliding part 2112 is greater than or equal to the axial dimension of the connecting hole 111. The sliding part 2112 is coaxially arranged with the main pipe and fits against the outer surface of the main pipe. Figure 1 In the coordinate system shown, guide grooves 16 are respectively provided on the left and right sides of the sliding part 2112 on the main pipe. The left and right ends of the guide part are respectively inserted into the guide grooves 16 and form a sliding fit with the guide grooves 16.

[0049] Furthermore, the upper end face of the first tube 2111 has an arc-shaped structure, and the cylindrical surface on which the upper end face of the first tube 2111 is located is the same cylindrical surface as the cylindrical surface on which the upper side face of the sliding part 2112 is located.

[0050] As one specific implementation method, according to Figure 1In the coordinate system shown, in this embodiment, guide plates 151 extending in the front-to-back direction are respectively provided on the outer side of the main pipe on the left and right sides of the branch component 2. The guide plates 151 have an arc-shaped structure that fits against the outer wall of the main pipe and are fixedly connected to the main pipe by welding. The guide plate 151 includes a connecting part 1511, and a supporting part 1512 extending towards the branch component 2 is provided on the side of the connecting part 1511 facing the branch component 2. The supporting part 1512 extends to the lower side of the sliding part 2112 of the branch pipe 21 and supports the branch pipe 21. The guide plates 151 and the outer wall of the main pipe together form the guide groove 16.

[0051] Furthermore, such as Figure 11 As shown, baffles 152 are respectively provided at both ends of the two guide plates 151. The baffles 152 are used to prevent the branch pipe 21 from slipping out of the guide groove 16.

[0052] like Figure 12 As shown, a smoke exhaust hose 22 is provided at the lower end of the branch pipe 21.

[0053] Furthermore, in order to facilitate quick connection with the exhaust port of the flue, the lower end of the exhaust hose 22 is provided with a connector 23.

[0054] In one specific embodiment, the connector 23 in this embodiment includes a connecting horizontal plate 231, which has a through hole allowing flue gas to pass through. A first connecting cylinder 232, coaxially arranged with the through hole, is provided on the upper side of the connecting horizontal plate 231. The first connecting cylinder 232 is inserted into the exhaust hose 22 from its lower end and is connected and fixed to the lower end of the exhaust hose 22 by a first clamp (not shown in the figure). For example, the inner diameter of the first connecting cylinder 232 is equal to the diameter of the through hole. A second connecting cylinder 233, coaxially arranged with the through hole, is provided on the lower side of the connecting horizontal plate 231. The outer side of the second connecting cylinder 233 has a tapered structure, and the outer diameter of the second connecting cylinder 233 gradually decreases in the direction away from the connecting horizontal plate 231.

[0055] Furthermore, a control valve 24 is provided on the branch pipe 21.

[0056] In one specific implementation, the control valve 24 described in this embodiment is a pneumatic electromagnetic flap valve.

[0057] In one specific embodiment, the branch pipe 21 in this example further includes a second pipe body 2121. A first connecting flange 2113 is provided at the lower end of the first pipe body 2111, and a second connecting flange 2122 is provided at the upper end of the second pipe body 2121. The control valve 24 is located between the first connecting flange 2113 and the second connecting flange 2122, and is fixedly and sealingly connected to the first connecting flange 2113 and the second connecting flange 2122 via a bolt assembly. The lower end of the second pipe body 2121 is inserted into the exhaust hose 22 from the upper end and is connected and fixed to the upper end of the exhaust hose 22 via a second clamp (not shown in the figure).

[0058] Furthermore, such as Figure 5 As shown, a first adjusting drive 31 is provided between two connected branch pipes 21. The fixed side of the first adjusting drive 31 is connected to one branch pipe 21, and the movable side of the first adjusting drive 31 is connected to the other branch pipe 21. One branch pipe 21 located at the end is connected to the main pipeline via a second adjusting drive 32. The fixed side of the second adjusting drive 32 is connected to the branch pipe 21, and the movable side of the second adjusting drive 32 is connected to the main pipeline. For example, according to... Figure 1 The coordinate system shown is located at the front end of the branch pipe 21, which is connected to the main pipe through the second adjustment drive component 32.

[0059] The reason for this design is that, since the fire channels 5 of the roasting furnace have a long, narrow structure, and the same temperature zones of each fire channel 5 are aligned, the temperature difference along the length of the same fire channel 5 is relatively large. However, for different fire channels 5, the temperature at the same length is similar. Therefore, the deformation produced at a certain position in each fire channel 5 is roughly the same. Figure 1 The coordinate system shown can be bent forward or backward. Thus, when adjusting according to the deformation of the fire duct 5, all branch pipes 21 can be adjusted synchronously using the second adjustment drive 32. Since the lower end of the branch pipe 21 is connected to the smoke exhaust port of the fire duct 5 via the smoke exhaust hose 22, the second adjustment drive 32 can basically meet the adjustment requirements. If some are still not satisfied, the first adjustment drive 31 can be used to fine-tune individual branch pipes 21, thereby improving the adjustment efficiency.

[0060] As one specific implementation method, such as Figure 5 , Figure 8 and Figure 9As shown, in this embodiment, both the first adjusting drive component 31 and the second adjusting drive component 32 are hydraulic cylinders. The fixed side refers to the cylinder body of the hydraulic cylinder, and the moving side refers to the piston rod of the hydraulic cylinder. For ease of understanding and description, the hydraulic cylinder serving as the first adjusting drive component 31 is now named the first hydraulic cylinder, and the hydraulic cylinder serving as the second adjusting drive component 32 is named the second hydraulic cylinder. The cylinder body of the first hydraulic cylinder is hinged to the branch pipe 21 located on the rear side via a first hinge shaft 311, and the rod end of the first hydraulic cylinder is hinged to the branch pipe 21 located on the front side via a second hinge shaft 312. The cylinder body of the second hydraulic cylinder is hinged to the branch pipe 21 located at the front end via a third hinge shaft 321, and the rod end of the second hydraulic cylinder is hinged to the main pipe via a fourth hinge shaft 322.

[0061] Furthermore, such as Figure 1 , Figure 3 and Figure 5 As shown, the main pipeline also includes two support frames 17 for supporting the main pipeline, and the two support frames 17 are respectively disposed at both ends of the horizontal section 11. The support frame 17 includes a bottom horizontal bar 171, and a plurality of vertical bars 172 extending upward in the vertical direction are disposed on the bottom horizontal bar 171. The upper end of the vertical bar 172 is fixedly connected to the main pipeline by welding, and the lower end of the vertical bar 172 is fixedly connected to the bottom horizontal bar 171 by welding.

[0062] As one specific implementation method, such as Figure 8 As shown, in this embodiment, the piston rod end of the second hydraulic cylinder is hinged to the support frame 17 located on the front side via the fourth hinge shaft 322.

[0063] Furthermore, to facilitate leveling of the main pipeline and adapt to complex installation environments, such as... Figure 7 As shown, a base plate 173 is provided on the lower side of the support frame 17. A screw 1731 extending upward perpendicularly to the base plate 173 is provided on the base plate 173. The support frame 17 is provided with a mounting hole for accommodating the screw 1731. Locking nuts 174 are respectively provided on the upper and lower sides of the mounting hole on the screw 1731.

[0064] In one specific embodiment, the support frame 17 in this embodiment has two base plates 173 on its lower side, and the two base plates 173 are respectively located at the left and right ends of the base frame. The two ends of the bottom horizontal plate are respectively provided with mounting holes for accommodating the screw 1731, and locking nuts 174 are respectively provided on the upper and lower sides of the bottom horizontal bar 171 on the screw 1731.

[0065] Furthermore, a ladder 4 is provided on the main pipeline. In one specific embodiment, the ladder 4 is located at the rear end of the horizontal section 11 of the main pipeline.

[0066] Furthermore, such as Figure 1 and Figure 2 As shown, the upper part of the horizontal section 11 of the main pipeline is provided with a plurality of cleaning ports 112, and the opening end of the cleaning port 112 is provided with a removable and washable cover plate 18.

[0067] In one specific implementation, the horizontal section 11 of the main pipeline in this embodiment is provided with two square cleaning ports 112. The opening end of the cleaning port 112 is provided with a flange plate, and the cover plate 18 is fixedly connected to the flange plate by a bolt assembly.

[0068] Furthermore, the upper part of the main pipe is provided with two first lifting lugs 113, and the two first lifting lugs 113 are arranged symmetrically about the center of the flexible roasting pipe.

[0069] Furthermore, a second lifting lug 181 is provided on the cover plate 18 at the geometric center of the cover plate 18.

[0070] Furthermore, the opening degree of the control valve 24 is adjusted according to the temperature of the low-temperature zone fed back by the temperature measuring component of the corresponding fire channel 5.

[0071] The temperature measuring component is an existing structure of an open-ring roasting furnace, and will not be described in detail here.

[0072] Example 2

[0073] according to Figure 1 In the coordinate system shown, guide rods are respectively provided on the left and right sides of the branch component 2 on the outside of the main pipe. Ear plates are respectively provided at both ends of each guide rod on the outer wall of the main pipe, and the ear plates are fixedly connected to the main pipe by welding. The two ends of the guide rod are respectively fixedly connected to the ear plates. Guide seats are respectively provided on the outer surface of the sliding part 2112 of the branch pipe 21 on the left and right sides of the first pipe body 2111. The guide seats are provided with guide holes that cooperate with the guide rods.

[0074] The rest of the structure is the same as in Example 1.

[0075] Example 3

[0076] The first pipe body 2111 is provided with a first limiting plate and a second limiting plate in an arc shape, arranged sequentially from top to bottom. The first limiting plate is located inside the main pipe, and the second limiting plate is located outside the main pipe. The side wall of the main pipe is clamped between the first limiting plate and the second limiting plate. The outer diameter of the first pipe body 2111 is equal to the dimension of the connecting hole 111 in the left-right direction. In this way, the connecting hole 111 can not only limit the axial sliding range of the branch pipe 21 relative to the main pipe, but also limit the relative swing of the branch pipe 21 around the axis of the main pipe.

[0077] Furthermore, the upper end face of the first tube 2111 has an arc-shaped structure, and the cylindrical surface on which the upper end face of the first tube 2111 is located is the same cylindrical surface as the cylindrical surface on which the upper side of the first limiting plate is located.

[0078] The rest of the structure is the same as in Example 1.
