Description

Technical Field

[0001] This utility model relates to the field of granule production technology, specifically to a granule manufacturing system. Background Technology

[0002] In recent years, ceramsite products have been widely used in many fields such as chemical industry, metallurgy, building materials, aviation and aerospace due to their excellent properties such as heat resistance, corrosion resistance, low thermal expansion and thermal conductivity.

[0003] Ceramsite production is a lightweight aggregate made from clay, shale, sludge, fly ash, and other raw materials through granulation and high-temperature calcination. The core process consists of four main stages: raw material preparation, granulation, calcination, and cooling. The quality of the product is closely related to the cooling method and speed during the sintering process.

[0004] In the existing technology, ceramsite needs to be conveyed by a stainless steel chain conveyor mechanism. At the same time, multiple cold air fans are set at intervals along the conveying path of the conveyor mechanism to cool the ceramsite by blowing cold air. When the ceramsite is conveyed on the conveyor mechanism, only the surface layer of ceramsite can come into contact with the cold air flow, while the inner layer of ceramsite cannot come into contact with the cold air flow. This can easily lead to poor cooling effect of the ceramsite, which is not conducive to the filling and storage of ceramsite. Utility Model Content

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0019] To address the technical problems of low cooling efficiency and poor cooling effect of granules in existing technologies, this solution provides a granule manufacturing system for producing ceramsite, which can improve the cooling efficiency of ceramsite.

[0020] Please see Figures 1-6 , Figures 1-6 According to one embodiment of the present invention, a pellet manufacturing system includes a calcination mechanism 1 and a cooling mechanism 2. The cooling mechanism 2 includes a cylinder 21, an air guide 22, a flow modifier 23, and an air conveying component 24. The cylinder 21 has a cavity. The top and bottom of the cylinder 21 are respectively provided with an inlet end and an outlet end communicating with the cavity. The inlet end is connected to the unloading end of the calcination mechanism 1. The air guide 22 is installed on the cylinder 21 and extends into the cavity. The air guide 22 has multiple air blowing parts extending radially along the cylinder 21. The flow modifier 23 is disposed in the cavity and connected to the air guide 22. The flow modifier 23 and the cylinder 21 enclose a curved channel communicating with the inlet end and the outlet end. The multiple air blowing parts are all located in the curved channel. The air conveying component 24 is connected to the air guide 22.

[0021] In actual use, the raw materials are made into spherical particles by the ceramsite making machine (not shown in the figure). The spherical particles are then transported to the calcining mechanism 1 for sintering. After the calcining mechanism 1 completes the sintering of the ceramsite, it is discharged through the discharge end of the calcining mechanism 1. The ceramsite enters the cavity through the feed end and rolls downward in the curved channel. The air conveying component 24 delivers cold air to the air guide component 22. The cold air is delivered to the curved channel through multiple air blowing parts, so that the cold air can come into contact with the rolling ceramsite and quickly remove the heat from the surface of the particles.

[0022] It should be noted that, in one embodiment, the raw materials are made into spherical particles by a ceramsite pelletizing machine, and the spherical particles are transported to the calcining mechanism 1 for sintering. The calcining mechanism 1 is a rotary kiln, which is a commonly used structure in the prior art and is not subject to any other limitations here.

[0023] In one embodiment, the air guide 22 includes a conduit 221 and a plurality of branch pipes 222. The conduit 221 is coaxially fixed in the cavity. The top of the conduit 221 is connected to the air conveying component 24, and the bottom of the conduit 221 is close to the discharge end. The plurality of branch pipes 222 are spaced apart along the axial direction of the conduit 221, and the branch pipes 222 have a plurality of air outlet holes along the axial direction.

[0024] Understandably, the bottom of the duct 221 is sealed by a cover plate, and the air supply component 24 (cooler) delivers cold air into the duct 221. The cold air can then be output from the air outlet on the branch pipe 222 into the curved channel. It should be noted that the multiple air outlets on the branch pipe 222 are all set towards the bottom of the cylinder.

[0025] It should be noted that the flow-retarding element 23 is not limited to a specific structure. In one embodiment, the flow-retarding element 23 is a first spiral blade fixed on the conduit 221. Specifically, the curved channel enclosed between the first spiral blade and the cylinder 21 is a spiral curved channel. Under its own gravity, the ceramic particles can roll in the curved channel, which can ensure that the surface of the ceramic particles can fully contact the cold airflow.

[0026] In one embodiment, to facilitate the conveying of the ceramic particles output from the calcining mechanism 1 into the cylinder 21, a first conveying mechanism 3 is specifically included. The first conveying mechanism 3 is installed between the unloading end of the calcining mechanism 1 and the feeding end of the cylinder 21. The first conveying mechanism 3 is used to convey the granules sintered by the calcining mechanism 1 into the cavity. It should be noted that the first conveying mechanism 3 can be a high-temperature resistant all-304 stainless steel chain conveyor in the prior art.

[0027] In another embodiment, the first conveying mechanism 3 may also be a guide trough inclined between the feeding end of the calcining mechanism 1 and the cylinder 21, and the ceramic particles output by the calcining mechanism 1 can be transported to the cylinder 21 through the guide trough.

[0028] Based on the above scheme, in order to further cool the ceramsite, a second conveying mechanism 4 is specifically included. The second conveying mechanism 4 includes a conveying cylinder 41, a shaft 42, a second spiral blade 43, a drive motor 44, and a blower 45. The feed inlet at one end of the conveying cylinder 41 is connected to the discharge end of the cylinder 21. The shaft 42 is coaxially and rotatably mounted on the conveying cylinder 41. The second spiral blade 43 is mounted on the shaft 42. The drive motor 44 is fixed at one end of the conveying cylinder 41 and fixedly connected to one end of the shaft 42. The shaft 42 has an air supply channel along the axial direction. The side wall of the shaft 42 has multiple exhaust holes connected to the air supply channel along the axial direction, and the air supply channel is connected to the blower 45.

[0029] Understandably, by blowing cold air into the air delivery channel through the blower 45 (cooler), the cold air can be diffused into the delivery cylinder 41 through multiple exhaust holes, which can further cool the ceramsite.

[0030] In addition, by driving the shaft 42 through the drive motor 44 to rotate the second spiral blade 43, the cooled ceramsite can be discharged from the discharge port at the other end of the conveying cylinder 41.

[0031] It should be noted that, in one embodiment, a dust removal mechanism 5 is also included. The dust removal mechanism 5 includes a dust removal box 51, a plurality of bag cylinders 52, an air extraction component 53, and a back-blowing component 54. The dust removal box 51 is provided with a dust removal chamber and an air blowing chamber. The dust removal chamber is connected to the top of the cylinder 21 via the air extraction component 53. The plurality of bag cylinders 52 are installed in the dust removal chamber. The plurality of bag cylinders 52 can absorb dust in the airflow and guide the airflow into the air blowing chamber. The back-blowing component 54 is installed on the dust removal box 51, and the back-blowing component 54 has a plurality of jet heads that correspond one-to-one with the openings of each of the bag cylinders 52. The back-blowing component 54 can output high-pressure airflow to each bag cylinder 52.

[0032] The dust collector 51 has an air outlet at the top connected to the air blowing chamber, and an ash discharge end at the bottom connected to the dust collection chamber. The ash discharge end is equipped with a control valve that can selectively seal the ash discharge end.

[0033] Understandably, the suction unit 53 draws the airflow inside the cylinder into the dust removal chamber, and the multiple bag cylinders 52 can absorb the dust in the airflow and guide the airflow into the blowing chamber, so that the airflow can be discharged from the outlet.

[0034] The back-blowing component 54 consists of a high-pressure gas storage tank and a jetting component. The high-pressure gas storage tank contains high-pressure gas and is fixed to the outside of the dust collector housing 51. The jetting component is installed in the blowing chamber and connected to the outlet of the high-pressure gas storage tank. The jetting component has multiple jet nozzles. In addition, a pulse control valve is provided on the outlet of the gas storage tank.

[0035] Based on the above solution, in order to avoid the inability to clean the dust on the bag cylinder 52 after the gas in the high-pressure gas storage tank is used up, the dust removal mechanism 5 specifically includes at least one dust shaking component 55. The dust shaking component 55 includes a dust shaking plate 551, a transmission rod 552, a reduction motor 553, and a cam 554. The opposite sides of the dust shaking plate 551 are movably disposed in the dust removal chamber via elastic members. The dust shaking plate 551 has multiple insertion holes 551a, and each bag cylinder 52 is correspondingly inserted into each insertion hole 551a. The reduction motor 553 is fixed to the outside of the dust removal box 51, and its output end is fixedly connected to the cam 554. One end of the transmission rod 552 is fixedly connected to one side of the dust shaking plate 551, and the other end of the transmission rod 552 extends to the outside of the dust removal box 51 and is provided with a rotatable roller 555. The roller abuts against the cam 554.

[0036] It is understandable that by driving the cam 554 through the geared motor 553, the dust shaking plate 551 can be driven to reciprocate in the horizontal direction, thereby driving multiple bag cylinders 52 to shake, which can shake off the dust on the bag cylinders 52.

[0037] It should be noted that some dust will also be generated when the calcination mechanism 1 outputs ceramsite. In one embodiment, the dust removal mechanism 5 further includes a dust suction hood 56, which is located above the first conveying mechanism 3 and is connected to the dust removal chamber via the air extraction member 53.

[0038] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
