Description

Technical Field

[0001] This utility model relates to the field of sludge treatment technology, and in particular to a drying and roasting device. Background Technology

[0002] Drying and roasting equipment is used for sludge treatment. It primarily removes moisture from the sludge through heating, reducing its water content to facilitate subsequent transportation, storage, and processing. Under high-temperature conditions, the sludge undergoes a series of physicochemical changes, such as the decomposition of organic matter and the transformation of inorganic matter. Tin-containing sludge, after drying and roasting, forms slag particles, which are a raw material for refining precious metals.

[0003] In existing technologies, some drying and roasting equipment typically uses manual packaging and storage after processing sludge into granules. The manual packaging and storage process is not only inefficient, but also easily generates dust. This dust, along with the harmful substances it contains, can pollute the air environment in the workshop, thereby affecting the health of the workers in the workshop. Utility Model Content

[0004] The purpose of this invention is to address the problem that some existing drying and roasting equipment uses manual packaging and storage of sludge particles, which easily generates dust that harms workers' health. This invention proposes a drying and roasting equipment.

The equipment also includes: a drive plate fixedly installed at the end of the discharge hopper away from the drying and roasting machine, and a loading mechanism for quantitatively filling the storage tank on the drive plate; and a conveying mechanism disposed at the bottom of the loading mechanism for conveying the filled storage tank.

[0006] Optionally, the loading mechanism includes a drive plate, a first intercepting plate is fixedly connected to the top of the drive plate, a conveying pipe is fixedly connected to the bottom of the discharge hopper, a intercepting groove is opened at the top of the conveying pipe for the first intercepting plate to insert into, a second intercepting plate is fixedly connected to the bottom of the drive plate to block the bottom of the conveying pipe, and a discharge port is opened at the end of the second intercepting plate near the drive plate.

[0007] Optionally, the loading mechanism further includes a V-shaped bracket fixedly connected to the outer wall of one end of the drying roaster, a support plate fixedly connected to the V-shaped bracket, a cylinder fixedly connected to the upper surface of the support plate, and the piston rod of the cylinder fixedly connected to the middle of the driving plate.

[0008] Optionally, a guide sleeve corresponding to the discharge port is fixedly connected to the lower surface of the second interceptor plate, and the guide sleeve is made of rubber.

[0009] Optionally, the conveying mechanism is connected to the drying roasting machine via a pair of connecting blocks.

[0026] Example

[0027] like Figures 1 to 4As shown, the present invention proposes a drying and roasting equipment, including a drying and roasting machine 1 and a discharge hopper 12 disposed at one end of the drying and roasting machine 1. A support frame is provided at the bottom of the drying and roasting machine 1, and one end of the outer wall of the support frame is fixedly connected to a conveying mechanism 4. A storage tank 5 is provided at the bottom of the discharge hopper 12 away from the drying and roasting machine 1, and a drive plate 2 is fixedly installed at the end of the discharge hopper 12 away from the drying and roasting machine 1. The conveying mechanism 4 is disposed at the bottom of the loading mechanism for conveying the filled storage tank 5. The storage tank 5 is made of stainless steel, which is a corrosion-resistant and well-sealed storage tank. Its main function is to safely and efficiently store sludge particles and prevent contamination or leakage. The conveying mechanism 4 is connected to the drying and roasting machine 1 through a pair of connecting blocks 6.

[0028] Among them, such as Figures 1 to 4 As shown, the drive plate 2 is equipped with a loading mechanism for quantitatively filling the storage tank 5. The loading mechanism includes the drive plate 2, with a first intercepting plate 21 fixedly connected to the top of the drive plate 2. A conveying pipe 13 is fixedly connected to the bottom of the discharge bin 12. The groove inside the conveying pipe 13 for material to slide is inclined, which ensures that the material at the top of the conveying pipe 13 will not slide down before the second intercepting plate 22 completely blocks the bottom of the conveying pipe 13, thus preventing the material at the top of the conveying pipe 13 from falling down before the bottom of the conveying pipe 13 is blocked. The top of the conveying pipe 13 has an intercepting groove 14 for the first intercepting plate 21 to be inserted. The bottom of the drive plate 2 is fixedly connected to a second intercepting plate 22 that blocks the bottom of the conveying pipe 13. The end of the second intercepting plate 22 near the drive plate 2 has a discharge port 23. The material in the conveying pipe 13 will only fall out when the discharge port 23 coincides with the conveying pipe 13.

[0029] In addition, such as Figure 1 As shown, the loading mechanism also includes a V-shaped bracket 3 fixedly connected to the outer wall of one end of the drying roaster 1. When the driving plate 2 moves towards the V-shaped bracket 3 and abuts against it, the V-shaped bracket 3 cannot completely disengage the first intercepting plate 21 from the intercepting slide 14. This ensures that the first intercepting plate 21 is stuck in the intercepting slide 14 to provide additional support for the piston rod of the cylinder 32. A support plate 31 is fixedly connected to the V-shaped bracket 3, and a cylinder 32 is fixedly connected to the upper surface of the support plate 31. The piston rod of the cylinder 32 is fixedly connected to the middle part of the driving plate 2.

[0030] It is worth noting that, such as Figures 2 to 3 As shown, a guide sleeve 24 corresponding to the discharge port 23 is fixedly connected to the lower surface of the second interceptor plate 22. The guide sleeve 24 is made of rubber and is a thin layer of rubber. When in use, it is completely inserted into the top opening of the storage tank 5. Its function is to block the dust caused by sludge particles falling into the storage tank 5.

[0031] Furthermore, such as Figure 1As shown, a ramp 41 is fixedly connected to the end of the conveying mechanism 4 away from the storage tank 5. The ramp 41 allows the storage tank 5 to slide downwards under the action of gravity. A plastic plate is provided on the ramp 41 to reduce friction and prevent the storage tank 5 from being unable to slide on the ramp 41.

[0032] Furthermore, such as Figure 2 As shown, the drying roasting machine 1 has a feeding hopper 11 at the end away from the discharge hopper 12. The end of the first intercepting plate 21 inserted into the intercepting slide 14 is designed with an axe-shaped structure. The axe-shaped structure ensures that when the first intercepting plate 21 is inserted into the conveying pipe 13, it can easily cut off the sludge that has accumulated together. At the same time, the first intercepting plate 21 will tightly abut against the inner wall of the conveying pipe 13, thereby ensuring that the material is completely intercepted.

[0033] In this embodiment, when using a drying and roasting device, such as Figure 1 As shown, sludge is first poured into the feed hopper 11, then processed into granules by the drying and roasting machine 1, and discharged from the discharge hopper 12. The processed sludge granules flow into the conveying pipe 13 under gravity, but are temporarily stored in the discharge hopper 12 by the blockage of the first intercepting plate 21. At this point, the cylinder 32 on the pallet 31 is activated. The piston rod of the cylinder 32 moves the plate 2, which in turn moves the first intercepting plate 21 and the second intercepting plate 22 until the second intercepting plate 22 blocks the bottom of the conveying pipe 13, preventing material from falling out. Simultaneously, the first intercepting plate 21 disengages from the intercepting chute 14, and the material in the discharge hopper 12 falls into the conveying pipe 13 under gravity until the conveying pipe 13 is full. Then, the cylinder 32 is activated again to... Figure 2 The process returns to the original state of the drying and roasting machine 1. Finally, the first intercepting plate 21 is inserted into the intercepting chute 14 to cut off the material at the top of the conveying pipe 13, while the bottom of the conveying pipe 13 coincides with the discharge port 23. As a result, all the material in the conveying pipe 13 falls into the storage tank 5 through the discharge port 23 and the guide sleeve 24 under the action of gravity. Then, the conveying mechanism 4 is started to transport the filled storage tank 5 to the ramp 41, and the ramp 41 is tilted to allow the storage tank 5 to slide slowly to the next process.

[0034] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
