Abstract

This utility model discloses a high-efficiency sludge carbonization furnace utilizing waste heat treatment, relating to the field of sludge carbonization furnace technology. The utility model includes a carbonization furnace: the furnace is equipped with a drive assembly, a transmission assembly, a rolling assembly, a dispersing assembly, a feeding assembly, and a discharging assembly. The utility model drives the transmission assembly installed at its output end to rotate by activating the drive assembly, which in turn drives the internally installed rolling assembly to rotate.

This allows the dispersing assembly to disperse the sludge, facilitating uniform heating and improving the carbonization efficiency of the sludge.

Description

Technical Field

[0001] This utility model belongs to the technical field of sludge carbonization furnace, and specifically relates to a high-efficiency sludge carbonization furnace that utilizes waste heat treatment. Background Technology

[0002] Sludge carbonization furnaces are thermochemical conversion devices used to treat municipal or industrial sludge. Under anaerobic or hypoxic conditions, they convert the organic matter in the sludge into carbon-rich solid products through heating, while also producing byproducts such as combustible gas and tar.

[0003] By conveying the dehydrated sludge into the interior of a carbonization furnace and heating it to a specific temperature, the organic matter in the sludge is decomposed, releasing volatile gases, tar, and water, thereby forming sludge char containing fixed carbon from the sludge residue.

[0004] In existing technologies, when heating a carbonization furnace, in order to prevent sludge from clumping and ensure that heat can penetrate evenly into the interior of the sludge, thereby avoiding local overheating or low-temperature dead zones, sludge is generally prevented from clumping by stirring. However, during the stirring process, the stirring device cannot evenly stir and break up the sludge, thereby reducing the carbonization efficiency of the sludge. Utility Model Content

[0005] To prevent sludge from clumping during heating in a carbonization furnace and to ensure that heat penetrates evenly into the sludge, thus avoiding localized overheating or low-temperature dead zones, stirring is generally used to prevent sludge clumping. However, during the stirring process, the stirring device cannot evenly stir and disperse the sludge, thereby reducing the carbonization efficiency of the sludge. This utility model proposes a high-efficiency sludge carbonization furnace that utilizes waste heat treatment to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a high-efficiency sludge carbonization furnace utilizing waste heat treatment, comprising a carbonization furnace:

[0008] The carbonization furnace is equipped with a drive assembly, a transmission assembly, a rolling assembly, a dispersing assembly, a feeding assembly, and a discharging assembly.

[0009] The drive component has its output end fixedly installed inside the transmission component so that the drive component can drive the transmission component to rotate;

[0010] A rolling assembly whose outer surface is fixedly mounted to the interior of a transmission assembly, so that the transmission assembly can drive the rolling assembly to roll when it rotates.

[0011] The dispersing component is fixedly installed on its outer surface and inside the rolling component so that the rolling component drives the dispersing component to disperse the sludge when it rolls.

[0012] The feeding component is internally connected to the interior of the rolling component, so that the feeding component can transport sludge into the interior of the rolling component;

[0013] The feeding component is fixedly connected on one side to the side of the rolling component so that the sludge is driven out of the inside of the feeding component when the rolling component rotates.

[0014] Furthermore, the drive assembly includes a support frame, one side of which is fixedly mounted to one side of the carbonization furnace, and a motor is fixedly mounted on one side of the support frame.

[0015] Furthermore, the transmission assembly includes a drive gear, the interior of which is fixedly mounted to the output end of the motor, and a driven gear is meshed with the surface of the drive gear.

[0016] Furthermore, the rolling assembly includes a sealing plate, one side of which is fixedly connected to one side of the support frame. A roller is rotatably mounted on the outer surface of the sealing plate. The outer surface of the roller is fixedly installed inside the driven gear. An arc-shaped plate is fixedly connected to the inner wall of the roller.

[0017] Furthermore, the disintegration assembly includes a toothed ring and a mounting cylinder. The outer surface of the toothed ring is fixedly mounted to the inside of the roller. A transmission gear is meshed with the inner surface of the toothed ring. A drive gear is meshed with the surface of the transmission gear. A drive shaft is fixedly mounted inside the drive gear.

[0018] The outer surface of the mounting cylinder is fixedly connected to the inside of the sealing plate. A disintegrating frame is rotatably installed inside the mounting cylinder. A first bevel gear is fixedly installed on the outer surface of the disintegrating frame. A second bevel gear is meshed with the surface of the first bevel gear. The inside of the second bevel gear is fixedly installed on the outer surface of the drive shaft.

[0019] Furthermore, the feeding assembly includes a feeding machine and an exhaust pipe. The discharge end of the feeding machine is fixedly installed on one side of the sealing plate, and an exhaust pipe is wound around the outer surface of the feeding machine. One end of the exhaust pipe is fixedly connected to one side of the sealing plate.

[0020] Furthermore, the feeding assembly includes a limiting block, one side of which is fixedly connected to one side of the sealing plate. A limiting groove is formed on one side of the limiting block, and a baffle is slidably arranged inside the limiting groove.

[0021] This utility model has the following beneficial effects:

[0022] 1. This utility model drives the transmission component installed at the output end of the start-up drive component to rotate, so that the transmission component drives the internally installed rolling component to rotate, so that the rolling component moves the sludge inside upward. As the sludge reaches the highest point inside the rolling component due to its own weight, it falls down. At the same time, when the rolling component rotates, it can drive the internally installed dispersing component to rotate, so that when the sludge falls downward inside the rolling component, it can fall into the rotation range of the dispersing component, so that the dispersing component can disperse the sludge, thereby facilitating uniform heating of the sludge and improving the carbonization efficiency of the sludge.

[0023] 2. This utility model uses a roller to drive an internally installed gear ring to rotate, which in turn drives a transmission gear meshing with the inner surface. Since the transmission gear has an internal support shaft, and one end of the support shaft is fixedly connected to one side of a sealing plate, when the transmission gear rotates, it rotates around the support shaft as its center. This causes the transmission gear to drive a surface-meshing drive gear to rotate, which in turn drives the internally installed transmission shaft to rotate. This allows the transmission shaft to drive a second bevel gear mounted on the outer surface to rotate, which in turn drives a surface-meshing first bevel gear to rotate. When the first bevel gear rotates, it drives an internally installed disintegrating frame to rotate, thus disintegrating the clumped sludge and preventing it from clumping during carbonization.

[0024] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Detailed Implementation

[0034] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0035] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0036] Please see Figures 1-6 As shown, this utility model is a high-efficiency sludge carbonization furnace utilizing waste heat treatment, including a carbonization furnace 1:

[0037] The carbonization furnace 1 is equipped with a drive assembly 2, a transmission assembly 3, a rolling assembly 4, a dispersing assembly 5, a feeding assembly 6, and a discharging assembly 7, respectively.

[0038] The drive component 2 is fixedly installed inside the transmission component 3 at its output end, so that the drive component 2 drives the transmission component 3 to rotate.

[0039] The rolling component 4 is fixedly installed on its outer surface to the interior of the transmission component 3 so that the transmission component 3 drives the rolling component 4 to roll when it rotates.

[0040] The dispersing component 5 is fixedly installed on its outer surface and inside the rolling component 4 so that the rolling component 4 drives the dispersing component 5 to disperse the sludge when it rolls.

[0041] The feeding component 6 is internally connected to the interior of the rolling component 4, so that the feeding component 6 can transport the sludge into the interior of the rolling component 4;

[0042] The feeding component 7 is fixedly connected on one side to the side of the rolling component 4 so that the sludge is driven out of the inside of the feeding component 7 when the rolling component 4 rolls.

[0043] In use, sludge is poured into the interior of the feeding component 6, and then the feeding component 6 is activated to push the sludge into the interior of the rolling component 4. Then, the drive component 2 is activated to drive the transmission component 3 installed at the output end to rotate, so that the transmission component 3 drives the internally installed rolling component 4 to rotate, so that the rolling component 4 moves the sludge inside upward. As the sludge reaches the highest point inside the rolling component 4 according to its own weight, it falls down. At the same time, when the rolling component 4 rotates, it can drive the internally installed dispersing component 5 to rotate, so that when the sludge falls downward inside the rolling component 4, it can fall into the rotation range of the dispersing component 5, so that the dispersing component 5 can disperse the sludge, which is convenient. By opening the discharging component 7, the carbonized sludge inside the rolling component 4 can be discharged easily.

[0044] This invention drives the transmission component 3 installed at the output end of the drive component 2 to rotate, which in turn drives the internally installed rolling component 4 to rotate. The rolling component 4 causes the sludge inside to move upward, and as the sludge reaches the highest point inside the rolling component 4 due to its own weight, it falls down. At the same time, when the rolling component 4 rotates, it can drive the internally installed dispersing component 5 to rotate, so that when the sludge falls downward inside the rolling component 4, it falls into the rotation range of the dispersing component 5, thereby dispersing the sludge. This facilitates uniform heating of the sludge and improves the carbonization efficiency of the sludge.

[0045] In one embodiment, the drive assembly 2 includes a support frame 201, one side of which is fixedly installed with one side of the carbonization furnace 1, and a motor 202 is fixedly installed on one side of the support frame 201.

[0046] The support frame 201 is designed to support the motor 202 mounted on one side, thereby providing a stable working environment for the motor 202.

[0047] In one embodiment, the transmission component 3 includes a drive gear 301, the interior of which is fixedly installed with the output end of the motor 202, and the surface of the drive gear 301 is meshed with a driven gear 302.

[0048] The starting motor 202 drives the drive gear 301 installed at the output end to rotate, so that the drive gear 301 drives the driven gear 302 that is meshed on the surface to rotate. Since the drive gear 301 is smaller than the driven gear 302, when the drive gear 301 rotates at a faster speed, the driven gear 302 rotates at a slower speed, thereby improving the stability of the driven gear 302 during rotation.

[0049] In one embodiment, the rolling assembly 4 includes a sealing plate 401, one side of which is fixedly connected to one side of the support frame 201. A roller 402 is rotatably mounted on the outer surface of the sealing plate 401. The outer surface of the roller 402 is fixedly installed inside the driven gear 302. An arc-shaped plate 403 is fixedly connected to the inner wall of the roller 402.

[0050] When the driven gear 302 rotates, it drives the internally installed roller 402 to rotate around the interior of the carbonization furnace 1 and the sealing plate 401. The roller 402 can also drive the internally fixed arc plate 403 to perform circumferential motion, so that the arc plate 403 can push the sludge inside the roller 402 to facilitate the discharge of the sludge.

[0051] In one embodiment, the dispersing component 5 includes a toothed ring 501 and a mounting cylinder 502. The outer surface of the toothed ring 501 is fixedly installed with the inside of the roller 402. The inner surface of the toothed ring 501 is meshed with a transmission gear 503. The surface of the transmission gear 503 is meshed with a drive gear 504. The inside of the drive gear 504 is fixedly installed with a transmission shaft 505.

[0052] The outer surface of the mounting cylinder 502 is fixedly connected to the interior of the sealing plate 401. A disintegrating frame 506 is rotatably installed inside the mounting cylinder 502. A first bevel gear 507 is fixedly installed on the outer surface of the disintegrating frame 506. A second bevel gear 508 is meshed with the surface of the first bevel gear 507. The interior of the second bevel gear 508 is fixedly installed on the outer surface of the drive shaft 505.

[0053] When the drum 402 rotates, it drives the internally mounted gear ring 501 to rotate, which in turn drives the inner surface meshing transmission gear 503 to rotate. Since the transmission gear 503 has an internal rotating support shaft, and one end of the support shaft is fixedly connected to one side of the sealing plate 401, when the transmission gear 503 rotates, it can rotate around the support shaft as the center, thereby driving the surface meshing drive gear 504 to rotate. This, in turn, drives the internally mounted transmission shaft 505 to rotate, so that the transmission shaft 505 drives the outer surface mounted second bevel gear 508 to rotate, which in turn drives the surface meshing first bevel gear 507 to rotate. When the first bevel gear 507 rotates, it drives the internally mounted disintegrating frame 506 to rotate, so that the disintegrating frame 506 can break up the clumped sludge, thereby preventing the sludge from clumping together during carbonization.

[0054] In one embodiment, the feeding assembly 6 includes a feeding machine 601 and an exhaust pipe 602. The discharge end of the feeding machine 601 is fixedly installed on one side of the sealing plate 401. An exhaust pipe 603 is wound around the outer surface of the feeding machine 601. One end of the exhaust pipe 602 is fixedly connected to one side of the sealing plate 401.

[0055] By pouring sludge into the feeder 601, the feeder can be started to push the sludge through the sealing plate 401 into the drum 402 for carbonization. The exhaust gas inside the drum 402 is discharged through the exhaust pipe 602, and one end of the exhaust pipe 602 and the exhaust pipe 603 are fixedly installed through an external pipe. The other end of the exhaust pipe 603 is installed with an extension pipe, so that the exhaust gas inside the exhaust pipe 602 can enter the exhaust pipe 603. Since the exhaust pipe 603 is connected to the inside of the feeder 601, the residual heat of the exhaust gas can be transferred to the inside of the feeder 601 through the exhaust pipe 603, thereby preheating the sludge inside the feeder 601.

[0056] In one embodiment, the feeding component 7 includes a limiting block 701, one side of which is fixedly connected to one side of the sealing plate 401. A limiting groove 702 is formed on one side of the limiting block 701, and a baffle 703 is slidably disposed inside the limiting groove 702.

[0057] By pulling the baffle 703 upward, it moves upward along the direction of the limiting groove 702, thereby connecting the outside world with the inside of the drum 402. As the drum 402 rotates, the carbonized sludge inside can be discharged.

[0058] Through the above technical solution, 1. The drive component 2 drives the transmission component 3 installed at the output end to rotate, so that the transmission component 3 drives the internally installed rolling component 4 to rotate, so that the rolling component 4 drives the sludge inside to move upward. As the sludge reaches the highest point inside the rolling component 4 according to its own weight, it falls down. At the same time, when the rolling component 4 rotates, it can drive the internally installed dispersing component 5 to rotate, so that when the sludge falls downward inside the rolling component 4, it can fall into the rotation range of the dispersing component 5, so that the dispersing component 5 disperses the sludge, thereby facilitating uniform heating of the sludge and improving the carbonization efficiency of the sludge.

[0059] 2. The roller 402 drives the internally installed gear ring 501 to rotate, which in turn drives the inner surface meshing transmission gear 503 to rotate. Since the transmission gear 503 has an internal rotating support shaft, and one end of the support shaft is fixedly connected to one side of the sealing plate 401, when the transmission gear 503 rotates, it can rotate around the support shaft as the center, thereby driving the surface meshing drive gear 504 to rotate. This, in turn, drives the internally installed transmission shaft 505 to rotate, so that the transmission shaft 505 drives the outer surface installed second bevel gear 508 to rotate, which in turn drives the surface meshing first bevel gear 507 to rotate. When the first bevel gear 507 rotates, it drives the internally installed disintegrating frame 506 to rotate, so that the disintegrating frame 506 can break up the clumped sludge, thereby preventing the sludge from clumping together during the carbonization process.
