Description

Technical Field

[0001] This utility model relates to the field of granulation equipment technology, and in particular to an air outlet device and granulation system for granulation equipment. Background Technology

[0002] In the raw powder granulation process, the granulation tower is the main granulation equipment. Its working principle is that the slurry is fed to the atomizing plate of the granulation tower by the feeder. The slurry is atomized by the rotation of the atomizing plate. The atomized slurry is dried into powder at 200°C in the granulation tower. The larger particles fall directly into the discharge port of the granulation tower.

[0003] The cyclone outlet of the granulation tower is connected in sequence to the air outlet pipe, cyclone tank, bag filter tank, and induced draft fan. The suction force of the induced draft fan draws the water and smaller particles in the slurry into the cyclone tank through the cyclone outlet of the granulation tower for two granulation processes. The granulated powder enters the storage tank through the discharge port of the cyclone tank. The remaining water and smaller particles enter the bag filter tank through the suction force of the induced draft fan for three granulation processes. The granulated powder and water are separated by the filter bags in the bag filter tank. The separated water is discharged by the suction force of the induced draft fan. The granulated powder enters the storage tank through the discharge port of the bag filter tank. All of the above processes are carried out at high temperatures.

[0004] However, during the production process, the air outlet pipe connecting the granulation tower and the cyclone tank often gets blocked, and the granulation powder often sticks and accumulates on the tank walls of the cyclone tank and the bag filter tank, which is very troublesome, time-consuming and labor-intensive to clean.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] The purpose of this invention is to provide an air outlet device and granulation system for granulation equipment to solve the problems existing in related technologies, effectively avoid clogging and accumulation of granulation powder, and improve work efficiency and production capacity.

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figure 1 As shown, this embodiment provides an air outlet device for a granulation equipment, including an air outlet pipe 1, a cyclone tank 2, a bag filter tank 3, and an induced draft fan 4 connected in sequence. The inlet of the air outlet pipe 1 is used to connect with the cyclone outlet of the granulation tower 5. A first striking mechanism 101 is provided on the air outlet pipe 1, which can strike the air outlet pipe 1 to cause the granulation powder on the inner wall of the air outlet pipe 1 to fall off. A second striking mechanism 201 is provided on the cyclone tank 2, which can strike the cyclone tank 2 to cause the granulation powder on the inner wall of the cyclone tank 2 to fall off. A third striking mechanism 301 is provided on the bag filter tank 3, which can strike the bag filter tank 3 to cause the granulation powder on the inner wall of the bag filter tank 3 to fall off.

[0026] Furthermore, the first striking mechanism 101, the second striking mechanism 201, and the third striking mechanism 301 are all pneumatic hammers.

[0027] In this embodiment, the outer wall of the air outlet duct 1 is wrapped with a first heat insulation layer 102.

[0028] In this embodiment, the outer wall of the cyclone tank 2 is wrapped with a second heat insulation layer 202.

[0029] In this embodiment, the outer wall of the bag tank 3 includes a third heat insulation layer 302.

[0030] Furthermore, the first insulation layer 102, the second insulation layer 202, and the third insulation layer 302 are all layered insulation structures; the layered insulation structure includes an insulation cotton layer and a stainless steel protective layer arranged sequentially from the inside to the outside.

[0031] Specifically, taking the installation of a layered heat insulation structure and an air hammer on the air outlet duct 1 as an example, first, a heat insulation cotton layer is installed on the outer wall of the air outlet duct 1, then a stainless steel protective layer is installed. Then, holes are made in the heat insulation cotton layer and the stainless steel protective layer of the air outlet duct 1, and the air hammer is installed at the opening. The same method is used to install the layered heat insulation structure and air hammer on the cyclone tank 2 and the bag tank 3.

[0032] The working principle of the air outlet device of the granulation equipment provided in this embodiment is as follows:

[0033] In use, the inlet of the air outlet pipe 1 is connected to the cyclone outlet of the granulation tower 5. The slurry is fed to the atomizing disc 501 of the granulation tower 5 by the feeder. The slurry is atomized by the rotation of the atomizing disc 501. The atomized slurry is dried into powder at 200°C in the granulation tower 5. The larger particles fall directly into the discharge port of the granulation tower 5. The suction of the blower 4 causes the water and smaller particles in the slurry to enter the cyclone tank 2 through the cyclone outlet of the granulation tower 5 for two granulations. The granulated powder enters the storage tank through the discharge port of the cyclone tank 2. The remaining water and smaller particles enter the bag tank 3 through the suction of the blower 4 for three granulations. The bag 303 in the bag tank 3 separates the granulated powder and water. The separated water is discharged by the suction of the blower 4. The granulated powder enters the storage tank through the discharge port of the bag tank 3. All of the above processes are carried out at high temperature.

[0034] During the granulation process described above, when the granulating powder enters the outlet pipe 1 through the cyclone inlet of the granulation tower 5, the air hammer on the outlet pipe 1 vibrates and strikes the outlet pipe 1 at a certain frequency, causing the granulating powder on the inner wall of the outlet pipe 1 to fall off and not stick to the pipe wall. Similarly, the cyclone tank 2 and the bag tank 3 also have the granulating powder stuck to the tank wall fall off through the vibration of the corresponding air hammer. The addition of air hammers effectively avoids the blockage of the outlet pipe 1 and the accumulation of granulating powder in the cyclone tank 2 and the bag tank 3, thereby improving work efficiency and production capacity. By adding a layered heat insulation structure to the outlet pipe 1, the cyclone tank 2 and the bag tank 3, it not only has the function of heat preservation, but also prevents the outlet pipe 1, the cyclone tank 2 and the bag tank 3 from overheating, avoiding burns to the workers, and effectively reducing the noise generated by the cyclone tank 2 and the bag tank 3 during operation.

[0035] This embodiment also provides a granulation system, including a granulation tower 5 and the above-mentioned granulation equipment air outlet device; a fourth striking mechanism 502 is provided on the granulation tower 5, which is preferably an air hammer. The air hammer strikes the granulation tower 5, causing the granulated powder in the granulation tower 5 to enter the discharge port of the granulation tower 5.

[0036] In this embodiment, the outer wall of the granulation tower 5 is wrapped with a fourth heat insulation layer 503. The fourth heat insulation layer 503 is also preferably a layered heat insulation structure. The layered heat insulation structure includes a heat insulation cotton layer and a stainless steel protective layer arranged sequentially from the inside to the outside, which can play the role of heat preservation, anti-scalding and noise reduction.

[0037] In summary, the granulation equipment air outlet device and granulation system provided in this embodiment have a simple structure. During use, they solve the problem of blockage in the air outlet pipe 1, cyclone tank 2 and bag tank 3, greatly improving work efficiency and production capacity. At the same time, they solve the problem of workers being burned during operation and also have the function of noise reduction.

[0038] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
