Abstract
Description
Technical Field
[0001] This application relates to the field of coke conveying technology, and in particular to an anti-collision device for coke feeding. Background Technology
[0002] In coking plants, dry quenching units or wet quenching systems typically use belt conveyors to transport finished coke. The coke conveyor head chute is a crucial component of the coke conveyor, and its function is to ensure a stable and continuous discharge of coke, thereby ensuring the normal operation of the coke production process. Therefore, the quality of the chute directly affects the stability, economy, and environmental friendliness of the coke conveying system.
[0003] However, during coke transfer and unloading, to ensure smooth transfer and prevent chute blockage during unloading, the chutes between the preceding and following transfer devices must have a sufficient discharge height difference to meet the coke conveying requirements. Due to this height difference, when coke is transferred and unloaded from high to low via the chutes, the coke falling from a high position onto the following transfer devices causes a violent impact. This impact force increases with the amount of coke transported, leading to greater damage to the subsequent transfer devices, reducing their service life, and ultimately affecting the normal operation of the coke conveying process. Furthermore, the increased impact force of falling coke may cause it to break again, generating coke dust. This coke dust deteriorates the coke transport environment, potentially harming the health of workers in that working environment. Utility Model Content
[0004] This application provides an anti-collision device for coke feeding, which solves the technical problems described in the background art above.
[0005] To solve the above-mentioned technical problems, this application adopts the following technical solution:
[0006] This application provides an anti-collision device for coke feeding, comprising:
[0007] The material feeding chute body has an installation opening and its bottom end is at a preset height from the coke metering equipment. A conveying trough is inclined downward through the installation opening, and the high end of the conveying trough is connected to the discharge port of the coke screening equipment.
[0008] A buffer assembly, comprising a plurality of first buffer plates and a plurality of second buffer plates; the plurality of first buffer plates and the plurality of second buffer plates are equally spaced and arranged at an angle downwards and alternately on the inner wall of the material discharge chute body and are all located below the material conveying chute, and are respectively arranged on two opposite inner side walls of the material discharge chute body.
[0009] Wherein, the length of the material conveying trough within the body of the discharge chute, the length of the first buffer plate, and the length of the second buffer plate are all 2 / 3 to 5 / 6 of the inner diameter of the discharge chute body in the first direction.
[0010] Optionally, the installation port is located near the top of the feeding chute body, and the vertical distance between the inner bottom surface of the conveying chute and the inner top surface of the installation port is greater than the coke particle size after being screened by the coke screening equipment.
[0011] Optionally, the preset height is 0.5 to 2 times the coke particle size.
[0012] Optionally, the bottom end of the feeding trough, the bottom end of the first buffer plate, and the bottom end of the second buffer plate are all at a predetermined distance from the inner wall of the feeding chute body opposite to them.
[0013] The preset distance is greater than the coke particle size.
[0014] Optionally, the buffer assembly further includes a plurality of first springs corresponding one-to-one with the plurality of first buffer plates and a plurality of second springs corresponding one-to-one with the plurality of second buffer plates;
[0015] Both ends of each first spring are respectively disposed on a support plate fixedly connected to the inner wall of the discharge chute body and on the lower surface of the first buffer plate; both ends of each second spring are respectively disposed on a support plate fixedly connected to the inner wall of the discharge chute body and on the lower surface of the second buffer plate.
[0016] Each of the first buffer plates and each of the second buffer plates is hinged to the inner wall of the material discharge chute body.
[0017] Optionally, a flexible damping layer of a first preset thickness is provided on the upper surface of both the first buffer plate and the upper surface of the second buffer plate.
[0018] The first preset thickness is 0.3cm to 0.8cm.
[0019] Optionally, the material chute body includes a vertical section and an inclined section;
[0020] Both the vertical section and the inclined section are rectangular in shape. The high end of the inclined section is connected to the bottom end of the vertical section. The angle between the inclined section and the installation port of the coke metering equipment is 15°~45°.
[0021] Optionally, both the vertical section and the inclined section are made of wear-resistant steel plate;
[0022] The inner bottom surface of the inclined section is provided with a wear-resistant layer of a second preset thickness;
[0023] The second preset thickness is 1.5cm to 3.3cm.
[0024] Optionally, an inspection door is provided on the side wall of the vertical section, and the inspection door is provided with a viewing window.
[0025] Optionally, a vibration motor is provided at the connection between the vertical section and the inclined section.
[0026] The anti-collision device for coke feeding provided in this application, through the arrangement of a feeding chute, multiple first buffer plates, and multiple second buffer plates, allows coke, after being screened by the coke screening equipment, to enter the feeding chute and fall from the bottom of the feeding chute onto the staggered first and second buffer plates arranged sequentially from top to bottom, and then onto the coke metering equipment from the bottom of the feeding chute body. This improves the sealing of the coke conveying process. Furthermore, the arrangement of multiple first and second buffer plates transforms the disordered vertical free fall of coke within the feeding chute body into a process where the coke is buffered sequentially by the staggered and downward-sloping first and second buffer plates arranged sequentially from top to bottom before naturally sliding down to the coke metering equipment from the bottom of the feeding chute body. This extends the path of the coke within the feeding chute body and slows down the falling speed of the coke, reducing the impact force of the coke falling onto the coke metering equipment, thereby reducing the impact and wear of the coke on the coke metering equipment and extending the service life of the coke metering equipment. The reduced speed at which coke falls decreases the likelihood of secondary coke breakage, thereby reducing the amount of coke dust generated. Therefore, this application not only ensures the normal operation of the coke conveying process but also provides a better working environment for workers, reducing the harm caused by coke dust. Furthermore, since the lengths of the conveying chute, the first buffer plate, and the second buffer plate within the chute body are all 2 / 3 to 5 / 6 of the inner diameter of the chute body in the first direction, coke falling from the lower end of the conveying chute can fall onto the first buffer plate, and vice versa. This ensures that the coke falls slowly and stably within the chute body, further reducing the impact and wear on the coke metering equipment. Attached Figure Description

Detailed Implementation
[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.
[0034] refer to Figures 1 to 4 This application provides an anti-collision device for coke feeding, comprising:
[0035] The chute body 100 has an installation port 101 with its bottom end at a preset height from the coke metering device 200. A conveying trough 300 is inclined downward through the installation port 101, and the high end of the conveying trough 300 is connected to the discharge port of the coke screening device 400. The installation port 101 and the conveying trough 300 allow the coke after being screened by the coke screening device 400 to enter the chute body 100 through the conveying trough 300 on the installation port 101. This not only ensures the sealing of the chute body 100, but also improves the smoothness of the coke conveying process due to the downward inclination of the conveying trough 300.
[0036] A buffer assembly 500 includes multiple first buffer plates 501 and multiple second buffer plates 502. The multiple first buffer plates 501 and multiple second buffer plates 502 are equally spaced and arranged diagonally downwards from top to bottom on the inner wall of the feeding chute body 100, all located below the conveying chute 300, and respectively arranged on opposite inner side walls of the feeding chute body 100. The arrangement of the multiple first buffer plates 501 and multiple second buffer plates 502 ensures that the coke flows from a disordered vertical direction within the feeding chute body 100. The free fall is transformed into a process where the coke is buffered by multiple first buffer plates 501 and second buffer plates 502 arranged alternately from top to bottom and inclined downwards before naturally sliding down to the coke metering device 200 from the bottom of the feeding chute body 100. This extends the travel distance of the coke within the feeding chute body 100 and slows down the falling speed, reducing the impact force of the coke falling onto the coke metering device 200. This reduces the impact and wear of the coke on the coke metering device 200, thereby extending the service life of the coke metering device 200.
[0037] Among them, the length of the material conveying trough 300 within the material discharge chute body 100, the length of the first buffer plate 501, and the length of the second buffer plate 502 are all the lengths of the material discharge chute body 100 in the first direction (see [reference]). Figure 1 The inner diameter of the feed chute 300 is 2 / 3 to 5 / 6 of the inner diameter of the feed chute 300. This allows the coke falling from the lower end of the feed chute 300 to fall onto the first buffer plate 501, and the coke falling from the lower end of the first buffer plate 501 to fall onto the second buffer plate 502, and the coke falling from the lower end of the second buffer plate 502 to fall onto the first buffer plate 501. This ensures that the coke can fall slowly and stably within the feed chute body 100, further reducing the impact and wear of the coke on the coke metering device 200.
[0038] The anti-collision device for coke feeding provided in this application, through the arrangement of a conveying trough 300, multiple first buffer plates 501, and multiple second buffer plates 502, ensures that the coke after being screened by the coke screening equipment 400 enters the conveying trough 300 and falls from the bottom of the conveying trough 300 onto the staggered first buffer plates 501 and second buffer plates 502 arranged sequentially from top to bottom, and then falls from the bottom of the feeding chute body 300 onto the coke metering equipment 200. This improves the sealing performance of the coke conveying process, and the arrangement of multiple first buffer plates 501 and multiple second buffer plates 502 further enhances the sealing performance of the coke. The coke, initially falling freely and vertically within the feeding chute 100, is now buffered sequentially by multiple staggered and downward-sloping first buffer plates 501 and second buffer plates 502 before naturally sliding down to the coke metering device 200 from the bottom of the chute body 100. This process extends the coke's descent distance within the chute body 100 and slows its descent speed, reducing the impact force on the coke metering device 200. This, in turn, reduces the impact and wear on the device, thus extending its service life. Furthermore, the reduced descent speed decreases the likelihood of secondary coke breakage, thereby reducing the amount of coke dust generated. Therefore, this application not only ensures the normal operation of the coke conveying process but also provides a better working environment for workers, reducing the harm caused by coke dust to their health.
[0039] In some embodiments, reference Figure 4 The installation port 101 in this application is opened near the top of the feeding chute body 100, which can extend the travel of coke in the feeding chute body 100, thereby reducing the falling speed of coke and reducing the impact force of coke on the coke metering device 200.
[0040] In addition, the vertical distance between the inner bottom surface of the conveying trough 300 and the inner top surface of the mounting port 101 is greater than the coke particle size after being screened by the coke screening equipment 400. This ensures that the coke after being screened by the coke screening equipment 400 can enter the discharge chute body 100 through the conveying trough 300 and the mounting port 101 and fall from the bottom of the conveying trough 300 onto the first buffer plate 501 or the second buffer plate 502. This ensures the sealing of the discharge chute body 100 while also ensuring the smoothness of the coke conveying process.
[0041] In some embodiments, the preset height in this application is 0.5 to 2 times the coke particle size.
[0042] In the above embodiments, the purpose of the preset height is to ensure that the coke falls smoothly from the bottom of the first buffer plate 501 or the second buffer plate 502 at the bottom of the feeding chute body 100 onto the coke metering device 200 without causing a large impact on the coke metering device 200. The specific value of the preset height can be set according to actual needs, and this application does not make a specific limitation on it here.
[0043] In some embodiments, the bottom ends of the conveying trough 300, the first buffer plate 501, and the second buffer plate 502 are all at a predetermined distance from the inner wall of the opposite discharge chute body 100. The predetermined distance is set to ensure that coke falling from the bottom end of the conveying trough 300 can fall smoothly onto the first buffer plate 501 or the second buffer plate 502, coke falling from the bottom end of the first buffer plate 501 can fall smoothly onto the second buffer plate 502, or coke falling from the bottom end of the second buffer plate 502 can fall smoothly onto the first buffer plate 501.
[0044] In addition, the preset distance is greater than the coke particle size. The value of the preset distance can be set according to actual needs, and this application does not impose a specific limitation on it.
[0045] In some embodiments, reference Figure 2 The buffer assembly 500 in this application further includes a plurality of first springs 503 corresponding one-to-one with a plurality of first buffer plates 501 and a plurality of second springs 504 corresponding one-to-one with a plurality of second buffer plates 502; wherein, the number of first springs 503 and second springs 504 can be set according to the number of first buffer plates 501 and second buffer plates 502, and the number of first buffer plates 501 and second buffer plates 502 can be set according to the height of the discharge chute body 100. Therefore, this application does not further limit the number of first springs 503 and second springs 504.
[0046] Specifically, both ends of each first spring 503 are respectively mounted on a support plate that is fixedly connected to the inner wall of the discharge chute body 100 (see...). Figure 2 On the lower surface of the first buffer plate 501, the two ends of each second spring 504 are respectively disposed on the support plate fixedly connected to the inner wall of the discharge chute body 100 and the lower surface of the second buffer plate 502; wherein each first buffer plate 501 and each second buffer plate 502 are hinged to the inner wall of the discharge chute body 100.
[0047] In the above embodiments, since the first buffer plate 501 is hinged to the discharge chute body 100, the coke falling onto the first buffer plate 501 exerts its own weight on the first buffer plate 501, pressing the first buffer plate 501 downwards. The first buffer plate 501 compresses the first spring 503 to a certain extent, and the first spring 503 overcomes this compression to lift the first buffer plate 501 upwards, thus mitigating the impact force on the first buffer plate 501. Furthermore, since the second buffer plates 502 are also hinged to the discharge chute body 100, the coke falling onto the second buffer plates 502 exerts its own weight on the second buffer plates 502, pressing the second buffer plates 502 downwards. The second buffer plates 502 compress the second spring 504 to a certain extent, and the second spring 504 overcomes this compression to lift the second buffer plate 502 upwards, thus mitigating the impact force on the second buffer plates 502. Therefore, the arrangement of the first spring 503 and the second spring 504, as well as the hinged connection between the first buffer plate 501 and the second buffer plate 502 and the discharge chute body 100, reduces the impact force on the first buffer plate 501 and the second buffer plate 502 caused by coke falling onto them, thereby extending the service life of the first buffer plate 501 and the second buffer plate 502.
[0048] In some embodiments, a flexible damping layer of a first preset thickness is provided on the upper surface of the first buffer plate 501 and the upper surface of the second buffer plate 502 in this application. The flexible damping layer can be made of rubber or silicone, and the specific material can be set according to actual needs; however, this application does not specifically limit its material. The purpose of the flexible damping layer is to reduce the impact force caused by coke falling onto the first buffer plate 501 and the second buffer plate 502, thereby preventing wear and tear on the first buffer plate 501 and the second buffer plate 502 and extending their service life.
[0049] Furthermore, the initial preset thickness is 0.3cm to 0.8cm. If the initial preset thickness is too small, the flexible damping layer may not effectively dampen the first buffer plate 501 and the second buffer plate 502, or it may waste the material of the flexible damping layer. Therefore, the initial preset thickness needs to be within a suitable range. A thickness between 0.3cm and 0.8cm not only ensures that the flexible damping layer provides good cushioning for the first buffer plate 501 and the second buffer plate 502, but also saves on the raw materials used in its production.
[0050] In some embodiments, reference Figures 1 to 4The material chute body 100 in this application includes a vertical section 102 and an inclined section 103. Specifically, both the vertical section 102 and the inclined section 103 are rectangular. The high end of the inclined section 103 is connected to the bottom end of the vertical section 102. The angle between the inclined section 103 and the installation port 101 of the coke metering device 200 is 15° to 45°. The angle between the inclined section 103 and the installation port of the coke metering device 200 can be set according to actual needs, and this application does not specifically limit it.
[0051] In the above embodiment, the inclined section 103 causes the velocity direction of the coke falling vertically from the lower end of the first buffer plate 501 or the lower end of the second buffer plate 502 of the vertical section 102 to change from a first velocity to a second velocity. The second velocity is a component of the first velocity and is less than the first velocity, thereby reducing the impact force of the coke on the coke metering device 200. The angle between the inclined section 103 and the mounting opening 101 of the coke metering device 200 is 15°~45°, which not only reduces the impact force of the coke on the coke metering device 200 but also allows the coke to fall smoothly onto the coke metering device 200, ensuring the smooth operation of the coke conveying process. The angle between the inclined section 103 and the mounting opening of the coke metering device 200 is 15°~45°.
[0052] In some embodiments, the vertical section 102 and the inclined section 103 in this application are both made of wear-resistant steel plate. The wear-resistant steel plate is a sheet material made by bonding a certain thickness of a high-hardness, high-wear-resistance alloy wear-resistant layer to the surface of ordinary low-carbon steel or low-alloy steel with good toughness and plasticity through a welding method. In other words, the vertical section 102 and the inclined section 13 of the feed chute body 100 made of wear-resistant steel plate in this application result in better wear resistance, impact resistance, heat resistance, and corrosion resistance of the feed chute body 100, thereby improving the service life of the feed chute body 100.
[0053] In addition, the inner bottom surface of the inclined section 103 is provided with a wear-resistant layer of a second preset thickness; wherein, the wear-resistant layer can be wear-resistant cast stone, the purpose of which is to improve the wear resistance of the inner bottom surface of the inclined section 103 and improve the service life of the inclined section 103.
[0054] Specifically, the second preset thickness is 1.5cm to 3.3cm. A larger second preset thickness would result in waste of material used to form the wear-resistant layer, while a smaller second preset thickness would lead to poor wear resistance. Therefore, the second preset thickness needs to be within a suitable range. A second preset thickness between 1.5cm and 3.3cm not only ensures the wear resistance of the inner bottom surface of the inclined section 103 but also avoids material waste. The specific value of the second preset thickness can be set according to actual needs, and this application does not impose a specific limitation on it.
[0055] In some embodiments, reference Figures 1 to 3 In this application, an inspection door 600 is provided on the side wall of the vertical section 102, and a viewing window 601 is provided on the inspection door 600.
[0056] In the above embodiments, by opening or closing the inspection door 600, it is convenient to carry out the installation, cleaning and maintenance of the first buffer plate 501 and the second buffer plate 502, and the setting of the viewing window 601 makes it convenient to observe the falling of coke in the vertical section 102, so that the falling process of coke is controllable.
[0057] In some embodiments, reference Figures 1 to 4 In this application, a vibration motor 700 is provided at the connection between the vertical section 102 and the inclined section 103. The specifications and model of the vibration motor 700 can be set according to actual needs, and this application does not impose specific limitations on it.
[0058] In the above embodiment, since there is a certain angle at the connection between the vertical section 102 and the inclined section 103, coke is prone to accumulate at the connection between the vertical section 102 and the inclined section 103. The vibration motor 700 uses the centrifugal force generated by the high-speed rotation of the shaft and the eccentric block to obtain the excitation force, and then transmits the excitation force to the connection between the vertical section 102 and the inclined section 103, thereby breaking up the coke accumulated at the connection between the vertical section 102 and the inclined section 103, avoiding blockage at the connection between the vertical section 102 and the inclined section 103, and ensuring the smoothness of the coke conveying process.
[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
