Description

Technical Field

[0001] The present invention relates to the technical field of paste conveying equipment, and in particular to a paste conveying equipment and method for resource-based production of prebaked anodes. Background Art

[0002] Prebaked anodes are made of petroleum coke and asphalt coke as aggregates and coal tar as binder. They are used as anode materials for prebaked aluminum electrolytic cells and play a dual role of conducting electricity and participating in chemical reactions. They are made of petroleum coke as raw material and coal tar as binder, and are processed through processes such as petroleum coke calcination, medium crushing, screening, fine crushing, asphalt melting, batching, kneading, molding, and roasting. During the kneading process, a paste containing aggregates and binders needs to be added. The paste usually needs to be kept at a certain temperature to maintain its fluidity. This requires that the paste needs to be kept at an appropriate conveying temperature during the conveying of the paste. At present, in the process of conveying the paste by using a chain conveyor in combination with a hopper, the insulation unit of the entire chain conveyor environment is usually adjusted. This causes a temperature difference due to the distance between a single hopper and a heating element, and it is impossible to ensure that the paste in each hopper is always within the appropriate conveying temperature range.

[0003] For example, the paste conveying equipment for resource-based production of prebaked anodes disclosed in Publication No. CN220431404U has the problem of being unable to accurately control the temperature of a single box on the conveying equipment, resulting in the paste in the box being easily hardened due to temperature changes, affecting the processing of prebaked anodes. The carbon anode paste temperature equalization device disclosed in Publication No. CN117184834A, although capable of disturbing the paste in a single hopper to make it evenly heated, does not change the heat generated by the heating element, and the heat transferred to each hopper does not change, resulting in only disturbing the paste in a single hopper, and being unable to ensure that the paste is always within the appropriate conveying temperature range;

[0004] Therefore, a paste conveying device and method for resource-based production of prebaked anodes are proposed. Summary of the Invention

[0024] The present invention provides a paste conveying device and method for resource-based production of prebaked anodes. Compared with the prior art, it has the following advantages:

[0025] (1) The paste conveying equipment and method for resource-based production of prebaked anodes can ensure that the paste maintains the best working condition during the entire conveying process by monitoring the viscosity of the paste in each hopper and adjusting the insulation temperature as needed, avoiding quality problems caused by inappropriate temperature, reducing conveying difficulties or equipment blockage caused by paste solidification or excessive viscosity, thereby improving the operating efficiency of the entire production line. Only the hoppers that need to adjust the temperature are heated instead of heating all the hoppers uniformly. This precise temperature control method can effectively reduce unnecessary energy consumption and achieve energy-saving goals. By maintaining an appropriate temperature range, it can prevent the volatile components in the paste from evaporating excessively, reduce the risk of fire or explosion, and improve the safety of the working environment.

[0026] (2) The paste conveying equipment and method for resource-based production of pre-baked anodes can effectively reduce residues by switching the shape of the flip plate in the detection component using an auxiliary component, ensuring that the paste in the hopper can be discharged quickly and thoroughly, ensuring the consistency of discharge, and providing a more stable supply of raw materials for subsequent processes, thereby improving the reliability of the overall process. By cleaning the hopper in a timely manner, the mechanical load and maintenance frequency of the equipment can be reduced, the service life of the equipment can be extended, and the residual paste in the hopper can be prevented from hardening or agglomerating, which increases the difficulty of cleaning during maintenance.

[0027] (3) The paste conveying equipment and method for resource-based production of prebaked anodes can fully discharge pastes of different viscosities, clean the hopper more thoroughly, and achieve almost "zero residue", thereby further reducing the waste of raw materials. The amount of discharged paste can be more accurately controlled each time the material is discharged, which helps to improve the consistency of the production process and product quality, reduce the need for equipment cleaning, extend the equipment maintenance cycle, reduce maintenance costs, and extend the production time. After the paste is completely discharged from the hopper, the energy required for subsequent heating or insulation will be less, reducing energy consumption, being more green and environmentally friendly, and improving economic benefits.

[0028] Other features and advantages of the present invention will be described in the following description, and part of them will become obvious from the description, or will be understood by practicing the present invention. The purpose and other advantages of the present invention can be realized and obtained by the structures particularly pointed out in the written description and the accompanying drawings.

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0043] In the embodiments of the present application, any device or element referred to or implied must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the embodiments of the present application. In the description of the embodiments of the present application, the meaning of "plurality" is two or more, unless otherwise specifically specified.

[0044] See also Figures 1 to 9 , the present invention provides the following technical solutions:

[0045] Embodiment 1: A paste conveying device for resource-based production of prebaked anodes, comprising a chain conveyor 1 for conveying paste, a column 11 for providing support for the chain conveyor 1, and a hopper 12 installed on the chain conveyor 1 for holding the paste and having an insulation unit, the hopper 12 being provided with a detection component for detecting the viscosity of the paste, the detection component comprising: a guide rod 2, a drive plate 201, a sliding block 21, a support rod 22, a disturbance plate 23, a flip plate 24, a protrusion 25, a flexible sleeve 26, a sliding rod 27, a limit sleeve 28, and a pressure sensor 29.

[0046] One end of the guide rod 2 is fixedly mounted on the side wall of the hopper 12, the bottom of the driving plate 201 is fixedly mounted on the top of the column 11, and one end of the sliding block 21 is slidably inserted into the guide rod 2. The sliding block 21 can move linearly along the guide rod 2 under the action of external force. The top of the support rod 22 is fixedly mounted on the bottom of the sliding block 21, and the bottom of the support rod 22 is fixedly mounted on the top of the disturbance plate 23. The support rod 22 provides support for the disturbance plate 23. The disturbance plate 23 is slidably mounted in the hopper 12, and the shape of the disturbance plate 23 is adapted to the inner cavity of the hopper 12. The disturbance plate 23 is used to disturb the paste. The flip plate 24 is movably mounted in the disturbance plate 23 through a movable shaft 241. The flip plate 24 flips with the movable shaft 241 as the axis under the squeezing of the paste. The flip plate 24 is used to judge the viscosity of the paste and adjust the temperature of the insulation unit according to the test results.

[0047] The bottom of the protrusion 25 is fixedly mounted on the flip plate 24, and the protrusion 25 moves with the flip plate 24. The protrusion 25 is used to assist in detecting the viscosity of the paste. The bottom of the flexible sleeve 26 is sleeved outside the protrusion 25. The flexible sleeve 26 can move while deforming under the drive of the protrusion 25. The flexible sleeve 26 is made of rubber material, and the part of the flexible sleeve 26 that is deformed under the drive of the protrusion 25 is corrugated. The bottom of the sliding rod 27 is fixedly mounted on the top of the flexible sleeve 26, and the sliding rod 27 moves under the drive of the flexible sleeve 26. The side wall of the limit sleeve 28 is fixed in the disturbance plate 23, and the inner wall of the limit sleeve 28 is slidably sleeved outside the sliding rod 27. The limit sleeve 28 is used to limit the moving direction of the sliding rod 27. One end of the pressure sensor 29 is fixedly mounted in the limit sleeve 28, and the pressure sensor 29 is used to detect the pressure value applied by the sliding rod 27.

[0048] When in use, the paste to be used in the production of pre-baked anodes is loaded into the hopper 12, and the column 11 provides support for the chain conveyor 1. The console controls the chain conveyor 1 to convey the hopper 12 filled with the paste to the vibration forming process. After the paste is vibrated and formed, it undergoes a series of processing steps such as cooling, roasting, cleaning, processing, and packaging to obtain the finished pre-baked anode product.

[0049] In the process of the chain conveyor 1 driving the hopper 12 to move and convey the paste, the paste is kept warm by the heat preservation unit in the hopper 12 so that the paste is at a suitable conveying temperature. At the same time, the column 11 provides support for the driving plate 201, and the hopper 12 provides support for the guide rod 2, dividing the entire chain conveyor 1 into multiple detection zones. In a single detection zone, two driving plates 201 are symmetrically arranged on both sides of the chain conveyor 1. Figure 1 、 Figure 2 As shown;

[0050] When the hopper 12 moves to the position of the driving plate 201, the driving plate 201 and the sliding block 21 are in sliding contact with each other, and the sliding block 21 and the guide rod 2 are in sliding cooperation. As the hopper 12 moves, the driving plate 201 squeezes the sliding block 21, so that the sliding block 21 can move to the other side along the guide rod 2;

[0051] During the movement of the sliding block 21, the sliding block 21 synchronously drives the support rod 22 to move, and the support rod 22 drives the disturbance plate 23 to move, and the disturbance plate 23 drives the flip plate 24 to move synchronously through the movable shaft 241. When the disturbance plate 23 moves linearly along the guide rod 2 under the action of external force, it will disturb the paste in the hopper 12. Since the shapes of the disturbance plate 23 and the inner cavity of the hopper 12 are adapted to each other, only the flip plate 24 is movable, and the paste will squeeze the flip plate 24 and flow through the flip plate 24 to the other side of the disturbance plate 23 opposite to the forward surface. In the process of the paste flowing through the flip plate 24, it will drive the flip plate 24 to flip around the movable shaft 241 as the axis. During the flipping process, the flip plate 24 synchronously drives the protrusion 25 to move, and the protrusion 25 squeezes the flexible sleeve 26 to move, and the flexible sleeve 26 drives the sliding rod 27 to move synchronously. Through the sliding cooperation between the sliding rod 27 and the limiting sleeve 28, the sliding rod 27 can move linearly along the limiting sleeve 28 under the drive of the flip plate 24.

[0052] By moving the sliding rod 27 along the limiting sleeve 28, the sliding rod 27 can contact the pressure sensor 29 in the limiting sleeve 28, thereby detecting the pressure. The viscosity of the paste is judged by the pressure value obtained by the detection. The larger the pressure value, the greater the resistance to the flip plate, and therefore the thicker the paste. Conversely, the smaller the pressure value, the smaller the resistance to the flip plate, and therefore the thinner the paste. The temperature of the heat preservation unit is thereby adjusted so that the paste in each hopper 12 can be maintained at an appropriate conveying temperature, and the problem of the paste becoming too viscous, increasing the difficulty of conveying, or the loss of volatile components, which may cause safety risks, will not occur.

[0053] In another embodiment different from the above embodiment, the detection assembly further includes: a driven slider 210, a spring 211, a driven plate 212, and a displacement sensor 213;

[0054] The bottom of the driven slider 210 slides against the top of the sliding rod 27, and the driven slider 210 moves under the drive of the sliding rod 27. One end of the spring 1 211 is fixedly installed in the disturbance plate 23, and the bottom of the driven plate 212 is fixedly installed on the top of the driven slider 210. The side wall of the driven plate 212 is fixedly connected to the other end of the spring 1 211. When there is no external force, the driven plate 212 can be reset under the elastic force of the spring 1 211. The bottom of the displacement sensor 213 is fixedly installed on the side wall of the sliding block 21 through the mounting plate. The displacement sensor 213 is located directly above the driven plate 212. By detecting the displacement of the driven plate 212, the viscosity of the paste can be assisted in judging.

[0055] Not only is the pressure sensor 29 used for conveying detection, but the sliding rod 27 can also squeeze the driven slider 210 to move simultaneously, so that the driven slider 210 drives the driven plate 212 to move upward. The displacement sensor 213 is used to detect the position change of the driven plate 212. Based on the dual comparison of the position change and the pressure value, the temperature control accuracy of the heat preservation unit is further improved.

[0056] The spring 1 211 provides the elastic force required for the reset of the driven plate 212 , so that when the disturbance plate 23 does not move, the driven plate 212 can be reset to the initial state under the action of the elastic force.

[0057] In another embodiment different from the aforementioned embodiment, a set of detection components can be set at both flip plates 24 within a single disturbance plate 23, and the detection values obtained at the two flip plates 24 can be compared with each other to further improve the accuracy of the detection results, thereby improving the accuracy of the temperature control of the insulation unit.

[0058] See also Figure 6 、 Figure 7 and Figure 10 , the present invention provides the following technical solutions:

[0059] In this embodiment, the technical solution different from the above-mentioned embodiment includes: an auxiliary component for changing the shape of the detection component to assist in discharging is provided on the hopper 12, and the auxiliary component includes: a power motor 3, a threaded rod 31, a power plate 32, a sliding plate 33, a second spring 34, an extrusion rod 35, a fixed rod 36, a third spring 37, an insertion rod 38, and a clamp 39; the bottom of the power motor 3 is fixed to the top of the sliding block 21 through the motor box, and the threaded rod 31 is fixed to the output end of the power motor 3 through a coupling, the power plate 32 is threadedly sleeved on the outside of the threaded rod 31 and threadedly matched with the threaded rod 31, and the power plate 32 can move under the drive of the threaded rod 31, one end of the sliding plate 33 is slidably penetrated in the disturbance plate 23, one end of the second spring 34 is fixedly installed at the bottom of the sliding plate 33, and the other end of the second spring 34 is fixedly installed in the disturbance plate 23 The top of the clamp 39 is fixedly mounted on the bottom of the fixing rod 36, and the clamp 39 is stuck outside the flip plate 24 under the drive of the fixing rod 36. The clamp 39 is used to assist the insertion rod 38 in fixing the position of the flip plate 24.

[0060] When the hopper 12 is in use, it moves to the unloading end under the drive of the chain conveyor 1, and the power motor 3 is started by controlling the console to control the threaded rod 31 to rotate. The threaded rod 31 and the power plate 32 are threadedly matched, and the power plate 32 and the support rod 22 are slidably matched, so that the power plate 32 can move linearly along the support rod 22 under the drive of the threaded rod 31, and the sliding plate 33 is synchronously squeezed by the power plate 32 when moving. The sliding plate 33 and the disturbance plate 23 are slidably matched, so that the sliding plate 33 can move linearly under the drive of the power plate 32, and the extrusion rod 35 is driven by the sliding plate 33 to move, and the extrusion rod 35 squeezes the fixed rod 36 to move, and the fixed rod 36 and the disturbance plate 23 are slidably matched, so that the fixed rod 36 can only move linearly under the squeezing of the extrusion rod 35, and the fixed rod 36 drives the insertion rod 38 to move synchronously, so that the insertion rod 38 can be inserted into the flip plate 24, so that the flip plate 24 remains Figure 6 In the state shown, a driving element is used to drive the sliding block 21, the support rod 22, and the disturbance plate 23 from one end of the hopper 12 to the other end, and the disturbance plate 23 and the flip plate 24 are used to scrape the paste in the hopper 12 to assist in discharging the paste from the hopper 12;

[0061] After the paste in the hopper 12 is discharged, the power motor 3 is controlled by the console to reverse, so that the power plate 32 is reset to the initial state. After the sliding plate 33 loses the squeezing force, the sliding plate 33 is reset under the action of the second spring 34. At the same time, the third spring 37 also applies elastic force to the fixing rod 36, so that the fixing rod 36 is reset to the initial state. Figure 7 shown.

[0062] See also Figure 6 、 Figure 7 、 Figure 11 and Figure 12 , the present invention provides the following technical solutions:

[0063] The technical solution of this embodiment is different from the previous embodiment in that: the hopper 12 is provided with a reinforcement component for changing the completeness of discharge, and the reinforcement component includes: an air storage bag 4, a pressure plate 41, a guide column 42, a magnet 43, an electromagnet 44, an air pipe 45, and a telescopic member 46;

[0064] The bottom of the air storage bag 4 is fixedly mounted on the top of the disturbance plate 23, and the air storage bag 4 is used to store gas. The bottom of the pressure plate 41 is fixedly mounted on the top of the air storage bag 4. The pressure plate 41 moves under the driving of external force, and the pressure plate 41 is used to transfer the gas in the air storage bag 4. The bottom of the guide column 42 is fixedly mounted on the disturbance plate 23, and the other end of the guide column 42 slides out from the pressure plate 41. The guide column 42 is used to limit the moving direction of the pressure plate 41. The side wall of the magnet 43 is fixedly mounted on the side wall of the pressure plate 41. The bottom of the electromagnet 44 is fixedly mounted on the top of the disturbance plate 23. The electromagnet 44 and the magnet 43 are magnetically matched. The electromagnet 44 is used to change the position of the pressure plate 41. One end of the air supply pipe 45 is connected to the air storage bag 4, and the side edge of the telescopic member 46 is fixedly mounted on the disturbance plate 23 and the flip plate 24. One of the side walls of the telescopic member 46 is connected to the other end of the air supply pipe 45, and the deformation part of the telescopic member 46 is raised under the action of external force.

[0065] The control console controls the auxiliary component to fix the position of the flip plate 24, and the control console synchronously controls the enhancement component to start. By switching the magnetic conversion after the electromagnet 44 is energized, the electromagnet 44 and the magnet 43 are magnetically attracted to each other, so that the magnet 43 drives the pressure plate 41 to move toward the side where the disturbance plate 23 is located, and the disturbance plate 23 provides a supporting force to the guide column 42, which guides the pressure plate 41 so that the pressure plate 41 can only move in a straight line along the guide column 42 when moving. In the process of the movement of the pressure plate 41, the pressure plate 41 squeezes the air bag 4, causing the air bag 4 to deform and the internal gas to be transported to the telescopic member 46 through the air supply pipe 45, so that the telescopic member 46 at the disturbance plate 23 and the flip plate 24 expands, thereby convexing, so that when the sliding block 21 is driven by the driving element to move from one end of the hopper 12 to the other end, the disturbance plate 23 and the flip plate 24 scrape the paste in the hopper 12, and the scraping effect of the paste is better.

[0066] After the paste is discharged, the control console is used to control the magnetic conversion of the electromagnet 44 after it is energized, so that the electromagnet 44 and the magnet 43 magnetically repel each other, so that the magnet 43 drives the pressing plate 41 to return to the Figure 11 The initial position shown is waiting for the next use.

[0067] Furthermore, a return spring can be added between the pressure plate 41 and the disturbance plate 23, so that the return spring provides an elastic force to the pressure plate 41 away from the side where the disturbance plate 23 is located, so that when the telescopic member 46 is not required to expand and bulge, the pressure plate 41 can be reset to the side under the combined action of the elastic force and the repulsive force. Figure 11 Status shown.

[0068] The embodiment of the present invention also provides a method for conveying paste conveying equipment suitable for resource-based production of prebaked anodes, comprising the following steps:

[0069] S1, the paste to be transported is loaded into the hopper 12, the paste is kept warm by the insulation unit, and the chain conveyor 1 is controlled by the console to drive the hopper 12 to feed the material;
