Description

Technical Field

[0001] The invention relates to the technical field of sludge drying, and in particular to a sludge drying and reducing device. Background Art

[0002] With the acceleration of urbanization and the rapid development of industrial production, the amount of sewage treatment has increased significantly. As a byproduct of sewage treatment, the amount of sludge produced has also risen sharply. Sludge has the characteristics of high water content, high organic matter content, easy to decompose and stink. If it is discharged directly without proper treatment, it will not only cause serious pollution to the environment, but also waste a lot of resources. Therefore, how to achieve the reduction, harmlessness and resource treatment of sludge in an efficient and environmentally friendly way has become a key issue that needs to be solved in the current environmental protection field.

[0003] As an effective sludge treatment method, sludge drying and reduction technology removes most of the water in the sludge through physical methods, significantly reducing the sludge volume, making it easier to transport, stack and recycle. Among the many sludge drying technologies, the hot air drying system has become one of the mainstream directions of sludge drying technology due to its precise temperature control and no risk of explosion.

[0004] However, in actual application, sludge drying and reduction equipment still faces many technical challenges. Among them, the problem of precise control of the distance between the sludge and the hot air nozzle when it is lifted and turned over is particularly prominent. In the sludge drying process, in order to ensure that the sludge is evenly heated and improve the drying efficiency, it is usually necessary to lift and turn the sludge over to keep a certain evaporation distance from the hot air nozzle. However, the distance between the sludge and the hot air nozzle will be shortened during the lifting process, which can easily lead to sludge gelatinization and may also produce harmful gases.

In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0037] Embodiment 1, referring to Figure 1-2 , which is an embodiment of the present invention, provides a sludge drying and volume reduction device, mainly including:

[0038] A turning assembly 100, which includes a turning part and a lifting part. The turning part is used to turn over the sludge, and the lifting part is used to lift the turning part;

[0039] An evaporation assembly 200, which includes a hot air blower 201, a main pipe 202, a number of fixed hot air drying components and a movable hot air drying component 203 connected to the main pipe 202. The air outlet of the hot air blower 201 is hermetically and slidably connected to the inner part of one end of the main pipe 202;

[0040] A reciprocating movement assembly 300, which is connected to the lifting part and the main pipe 202 and is used to drive the main pipe 202 to move back and forth;

[0041] An evaporation distance adjustment assembly 400, which is connected to the reciprocating movement assembly 300 and the movable hot air drying component 204, and is used to ensure a set evaporation distance when the sludge is turned over by the turning part.

[0042] In this embodiment, in the present invention, the sludge is lifted and turned over by the flipping component 100 to improve the sludge drying efficiency. During the lifting process, the reciprocating moving component 300 can drive the first hot air nozzle 205 and the second hot air nozzle 203-4 to move back and forth, so as to improve the uniformity of sludge drying. In addition, during the process of lifting and turning over the sludge, through the evaporation distance adjusting component 400, the second hot air nozzle 203-4 can be driven to move up synchronously, so as to always ensure an appropriate evaporation distance between the second hot air nozzle 203-4 and the sludge surface, thus effectively avoiding the gelatinization phenomenon caused by the sharp increase in the sludge surface temperature due to too close a distance, and at the same time reducing the risk of generating harmful gases due to local overheating.

[0043] Example 2, refer to Figure 3 , which is an embodiment of the present invention. The difference between this embodiment and the first embodiment is that the flipping component includes a flipping scraper 101, a connecting plate 102 fixedly connected to one end of the flipping scraper 101, and a flipping motor 103 fixedly connected to the connecting plate 102 by bolts. The flipping motor 103 is connected to the lifting component.

[0044] The lifting component includes a fixing plate 104. An elevating cylinder 105 is fixedly installed on the fixing plate 104 by bolts. The piston end of the elevating cylinder 105 is fixedly connected to a support plate 106 by bolts. The support plate 106 is fixedly connected to the flipping motor 103 by bolts.

[0045] In this embodiment, when the sludge is carried on the flipping scraper 101 through the conveying action of the conveyor belt 502, the conveyor belt 502 stops conveying, and then the elevating cylinder 105 drives the support plate 106 to move upward. The support plate 106 drives the flipping scraper 101 to move upward through the flipping motor 103. When the flipping scraper 101 rises to a position sufficient for turning over, the upward movement stops, and then the flipping motor 103 is started. The output end of the flipping motor 103 drives the flipping scraper 101 to rotate, so as to turn over the sludge. After turning over, the elevating cylinder 105 drives the flipping scraper 101 to move downward to reset, and then the sludge is continuously conveyed to the flipping scraper 101 through the conveyor belt 502.

[0046] Example 3, refer to Figure 4 , which is an embodiment of the present invention. The difference between this embodiment and the first embodiment is that a plurality of fixed hot air drying components are arranged in an array at one end of the main pipe 202. The fixed hot air drying component includes a first branch pipe 206 fixedly communicated with the main pipe 202, a plurality of fixed hot air shunt pipes 204 fixedly communicated with the first branch pipe 206, and a first hot air nozzle 205 fixedly communicated with one end of the fixed hot air shunt pipe 204.

[0047] A number of movable hot air drying components 203 are arranged in an array at the other end of the shunt pipe 202. The movable hot air drying component 203 includes a second shunt pipe 203-3 fixedly communicated with the main pipe 202, a number of fixed pipes 203-1 fixedly communicated with the second shunt pipe 203-3, a movable pipe 203-2 externally sealed and slidably connected to the fixed pipe 203-1, and a second hot air nozzle 203-4 fixedly communicated with one end of the movable pipe 203-2.

[0048] The movable hot air drying component 203 is arranged at the rear side of the fixed hot air drying component. After being dried by the fixed hot air drying component first, it is further dried by the movable hot air drying component 203. The specific operation is as follows: The hot air blower 201 operates to generate hot air, and the hot air is conveyed through the main pipe 202 into each fixed hot air shunt pipe 204 and the fixed pipe 203-1, and then is sprayed onto the surface of the sludge by the first hot air nozzle 205 and the second hot air nozzle 203-4 to dry the sludge.

[0049] Example 4, referring to Figure 5 , which is an embodiment of the present invention. The difference between this embodiment and the first embodiment is that the reciprocating moving component 300 includes a moving part connected to the main pipe 202 and a driving part connected to the support plate 106. The driving part is connected to the moving part and is used to drive the moving part to move when the support plate 106 is lifted.

[0050] The moving part includes a pair of guiding sliders 301 welded and fixed to the main pipe 202, a first guiding slide bar 302 slidably connected to the pair of guiding sliders 301, a pair of mounting blocks 303 respectively bolted to both ends of the first guiding slide bar 302, and a return spring 304 fixedly connected between the mounting block 303 and the guiding slider 301. The return spring 304 is movably sleeved outside the first guiding slide bar 302. When the main pipe 202 moves in one direction and is not under force, it can move and reset under the action of the return spring 304. Both of the pair of guiding sliders 301 are connected to the driving part.

[0051] The driving part includes a U-shaped plate 305 fixedly connected to the pair of guiding sliders 301, a pair of driving blocks 306 fixedly connected to the U-shaped plate 305, and push rods 307 respectively connected to the pair of driving blocks 306;

[0052] On the same side of the pair of driving blocks 306, inclined surfaces 308 are provided. The tops of the pair of push rods 307 are respectively in active contact with the pair of inclined surfaces 308, and the bottoms of the pair of push rods 307 are both fixedly connected to the support plate 106.

[0053] In this embodiment, when the lifting cylinder 105 drives the support plate 106 to move upward, the support plate 106 synchronously drives the push rod 307 to move upward. The top end of the push rod 307 drives the driving block 306 to move away from the first hot air nozzle 205 through the cooperation with the inclined surface 308. The driving block 306 drives the guiding slider 301 to slide along the first guiding slide rod 302 through the U-shaped plate 305. The guiding slider 301 drives the main flow pipe 202 to move synchronously. The main flow pipe 202 drives the first hot air nozzle 205 and the second hot air nozzle 203-4 to move for drying operation, which can improve the uniformity of sludge drying.

[0054] Embodiment 5, refer to Figure 6 , which is an embodiment of the present invention. The difference between this embodiment and the first embodiment is that the evaporation distance adjustment assembly 400 includes a lifting plate 401 fixedly sleeved outside the movable pipe 203-2, a plate 402 fixedly connected to one side of the lifting plate 401, a second guiding slide rod 403 fixedly connected to the plate 402, and a sliding sleeve 404 slidably engaged with the second guiding slide rod 403. One end of the sliding sleeve 404 is fixedly connected to the push rod 307.

[0055] In this embodiment, when the push rod 307 moves upward, that is, when the sludge is lifted, the sliding sleeve 404 moves upward following the push rod 307, and the sliding sleeve 404 drives the plate 402, the lifting plate 401, etc. to move upward through the second guiding slide rod 403. The lifting plate 401 drives the movable pipe 203-2 to move upward along the fixed pipe 203-1. The movable pipe 203-2 drives the second hot air nozzle 203-4 to move upward. Thus, when the sludge is lifted, the second hot air nozzle 203-4 can be synchronously moved upward, so as to always ensure an appropriate evaporation distance between the second hot air nozzle 203-4 and the sludge surface, effectively avoiding the gelatinization phenomenon caused by the rapid increase of the sludge surface temperature due to too close distance, and at the same time reducing the risk of generating harmful gases due to local overheating.

[0056] Embodiment 6, refer to Figure 7-8 , which is an embodiment of the present invention. The difference between this embodiment and the first embodiment is that the device further includes a conveying assembly 500. The conveying assembly 500 includes a frame 501, a conveyor belt 502 installed in the frame 501, and an evaporation box 503 fixedly connected to the frame 501. An avoidance groove 504 is opened at the top of one side of the frame 501. The connecting plate 102 is adaptively engaged in the avoidance groove 504. The purpose of such a setting is to block the avoidance groove 504 so that the sludge is not likely to fall to the ground through the avoidance groove 504 during the conveying process. The hot air blower 201 is fixedly connected to the top of the evaporation box 501. The main flow pipe 202 is located inside the evaporation box 501 and above the conveyor belt 502. The fixing plate 104 is fixedly connected to the inner wall of the evaporation box 503.

[0057] In summary, for sludge drying and volume reduction, the sludge is conveyed into the evaporation tank 503 through the conveyor belt 502 and first undergoes drying treatment by the first hot air nozzle 205. When the sludge is conveyed to the flipping scraper 101 and the flipping scraper 101 carries the sludge under the conveyance of the conveyor belt 502, the conveyor belt 502 stops conveying. Then, the lifting cylinder 105 drives the support plate 106 to move upward. The support plate 106 drives the flipping scraper 101 to move upward through the flipping motor 103. When the flipping scraper 101 rises to a position sufficient for flipping, the upward movement stops. Then, the flipping motor 103 is started, and the output end of the flipping motor 103 drives the flipping scraper 101 to rotate, thereby flipping the sludge. After flipping, the lifting cylinder 105 drives the flipping scraper 101 to move downward and reset, and then the sludge is continuously conveyed to the flipping scraper 101 through the conveyor belt 502. When the lifting cylinder 105 drives the support plate 106 to move upward, the support plate 106 synchronously drives the push rod 307 to move upward. The top end of the push rod 307 drives the driving block 306 to move away from the first hot air nozzle 205 through the cooperation with the inclined surface 308. The driving block 306 drives the guiding slider 301 to slide along the first guiding slide rod 302 through the U-shaped plate 305. The guiding slider 301 drives the main flow pipe 202 to move synchronously. The main flow pipe 202 drives the first hot air nozzle 205 and the second hot air nozzle 203 - 4 to move for drying operations, which can improve the uniformity of sludge drying. When the push rod 307 moves upward, that is, when the sludge lifting action is performed, the sliding sleeve 404 moves upward following the push rod 307, and the sliding sleeve 404 drives the plate 402, the lifting plate 401, etc. to move upward through the second guiding slide rod 403. The lifting plate 401 drives the movable pipe 203 - 2 to move upward along the fixed pipe 203 - 1. The movable pipe 203 - 2 drives the second hot air nozzle 203 - 4 to move upward. Thus, when the sludge lifting action is performed, the second hot air nozzle 203 - 4 can be synchronously moved upward, so as to always ensure an appropriate evaporation distance between the second hot air nozzle 203 - 4 and the sludge surface, effectively avoiding the gelatinization phenomenon caused by the sharp increase in the sludge surface temperature due to too close a distance, and at the same time reducing the risk of generating harmful gases due to local overheating.

[0058] It should be noted that: the entire device is controlled by a controller. Since the controller is a commonly used device and belongs to the existing mature technology, the electrical connection relationship and the specific circuit structure thereof will not be elaborated herein.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
