Description

Technical Field

[0001] This utility model relates to the field of expansion furnace technology, and in particular to an expansion device for perlite production. Background Technology

[0002] Expanded perlite powder is an ultra-lightweight, heat-insulating material made from perlite ore formed by volcanic eruptions. It is produced through preheating and high-temperature roasting, resulting in rapid and instantaneous expansion. It is lightweight, heat-insulating, sound-absorbing, non-combustible, anti-aging, corrosion-resistant, and insect-resistant. It also boasts a pure white color, is non-toxic and odorless, meeting the requirements of green, environmentally friendly, and energy-saving practices.

[0003] In existing perlite production processes, the perlite is calcined by flames after entering the furnace. However, when using a single stirring mechanism, some materials tend to accumulate, affecting the heating area and reducing the quality of the expanded material. Therefore, we propose an expansion device for perlite production. Utility Model Content

[0004] The present invention aims to solve the technical problems existing in the prior art and provide an expansion device for perlite production.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an expansion device for perlite production, comprising a furnace body, a drive roller rotatably disposed inside the furnace body, several sets of mutually cooperating sealing plates installed around the drive roller, a discharge cavity formed between each pair of sealing plates, a connecting plate installed between each pair of sealing plates, an installation groove formed inside the connecting plate, a burner head installed inside the installation groove, a gas pipe cooperating with the burner head pipe passing through the periphery of the drive roller, and a guide plate disposed between each pair of sealing plates. The guide plate has two sets of built-in slots inside, and a telescopic plate is telescopically installed inside the built-in slot. A first spring is fixedly connected to the telescopic plate inside the built-in slot. A sleeve is installed on one side of the guide plate. A telescopic shaft is telescopically installed inside the sleeve. One end of the telescopic shaft is fixedly connected to the connecting plate, and the other end of the telescopic shaft is limited and engaged with the inside of the sleeve through a limiting member. A second spring is provided inside the sleeve and supported and connected to the limiting member. A drive shaft is driven through the bottom of the furnace body and driven and connected to the bottom of the drive roller. One end of the drive shaft is connected and engaged with an external drive motor.

[0006] Preferably, when the drive shaft drives the several sets of packaging clamps around the drive roller to rotate, the material between every two sets of packaging clamps is in a swinging and pressing state against the guide plate by centrifugal force. When the guide plate is elastically reset by the second spring inside the sleeve, the guide plate is in a pushing state against the material between every two sets of packaging clamps.

[0007] Preferably, when the guide plate is pressed and moved by the material, the telescopic plate inside the guide plate is in a corresponding telescopic movement state through the first spring.

[0008] Preferably, a bearing ring is installed on one side of the telescopic plate via a connector, and a round shaft is rotatably connected to the inner side of every two sets of bearing rings. A limiting roller is sleeved on the outside of the round shaft, and a limiting groove is opened on one side of every two sets of encapsulation clamps. The telescopic plate is limited and slidably engaged with the inner side of the limiting groove via the limiting roller.

[0009] Preferably, the bottom of the furnace body is provided with a damping pad sleeved on the outside of the drive shaft. The damping pad itself has deformation characteristics. The bottom of the damping pad has a through groove that penetrates the furnace body. The through groove is connected and cooperates with each pair of encapsulation clamps. The drive shaft is rotatably sleeved with a bushing. A sealing plate for sealing the through groove is installed around the bushing. A control handle is installed around the bushing.

[0010] Preferably, the sealing plate structure is adapted to the shape of the through groove opening. When the sealing plate outside the bushing is rotated away from the through groove by controlling the control handle, the expanded material inside each pair of the encapsulation clamps is in a discharge state.

[0011] This invention provides an expansion device for perlite production. It has the following advantages:

[0012] 1. This is an expansion device for perlite production. In this invention, after the material is fed between two sets of packaging plates, the drive shaft drives the drive roller to rotate via an external motor. The drive roller can cause the material between the two sets of packaging plates to rotate and swing. When the material swings, the centrifugal force can press against the guide plate. As the sleeve moves with the guide plate, it stretches the second spring. After the guide plate is reset and pulled by the characteristics of the second spring, the guide plate will press against the material again. In this way, the guide plate can reciprocate to press against the material, causing the material to swing back and forth. At the same time, multiple sets of flame heads can calcine and heat the material, so that the swinging material is heated evenly, thereby increasing the heating area of ​​the material and improving the expansion quality of the material.

[0013] 2. An expansion device for perlite production, wherein a damping pad is provided at the bottom of the furnace body, and a through groove is opened on the surface of the damping pad corresponding to the inner cavity of each pair of encapsulation clamps. The drive shaft is connected to a sealing plate that closes and seals the through groove through a bushing. When discharging material inside the furnace body, the bushing is rotated by controlling the control handle, and the sealing plate outside the bushing can rotate and separate on the surface of the through groove. The material between the two sets of encapsulation clamps can then be quickly discharged through the open through groove, thereby achieving the effect of convenient material handling.

[0025] Example: An expansion device for perlite production, such as Figures 1-6As shown, the furnace includes a furnace body 1. A drive roller 2 is rotatably mounted inside the furnace body 1. Several sets of two-to-two sealing clamps 3 are installed around the drive roller 2. A material discharge chamber is formed between each pair of sealing clamps 3. A connecting plate 4 is installed between each pair of sealing clamps 3. An installation groove 5 is opened inside the connecting plate 4, and a burner head 6 is installed inside the installation groove 5. A gas pipe 7, which mates with the burner head 6, is passed through the periphery of the drive roller 2. A guide plate 8 is positioned between each pair of sealing clamps 3. Two sets of internal grooves 9 are opened inside the guide plate 8. A telescopic plate 10 is telescopically mounted inside the internal groove 9. A first spring 11, fixedly connected to the telescopic plate 10, is installed inside the internal groove 9. A sleeve 12 is installed on one side of the guide plate 8. A telescopic shaft 13 is telescopically mounted inside the sleeve 12. One end of the telescopic shaft 13 is fixedly connected to the connecting plate 4, and the other end of the telescopic shaft 13 is limited and engaged inside the sleeve 12 by a limiting member 14. A support is provided inside the sleeve 12 that interacts with the limiting member 14. The second spring 26 is connected to the support. A drive shaft 20 is installed through the bottom of the furnace body 1 and is driven to the bottom of the drive roller 2. One end of the drive shaft 20 is connected to an external drive motor. A bearing ring 16 is installed on one side of the telescopic plate 10 through a connector 15. A round shaft 17 is rotatably connected to the inner side of every two sets of bearing rings 16. A limiting roller 18 is installed on the outside of the round shaft 17. A limiting groove 19 is opened on one side of every two sets of sealing clamps 3. A limiting roller 19 is installed on one side of the telescopic plate 10 through a limiting roller. The wheel 18 is in a limiting sliding fit with the inner side of the limiting groove 19. The bottom of the furnace body 1 is provided with a damping pad 21 sleeved on the outside of the drive shaft 20. The damping pad 21 has deformation characteristics. The bottom of the damping pad 21 is provided with a through groove 22 that penetrates the furnace body 1. The through groove 22 is connected and engaged with each pair of encapsulation clamps 3. The drive shaft 20 is rotatably sleeved with a bushing 23. A sealing plate 24 is installed on the outside of the bushing 23 to seal the through groove 22. A control handle 25 is installed on the outside of the bushing 23.

[0026] Furthermore, when the drive shaft 20 drives the several sets of packaging clamps 3 around the drive roller 2 to rotate, the material between each two sets of packaging clamps 3 is in a swinging and pressing state against the guide plate 8 by centrifugal force.

[0029] The working principle of this utility model:

[0030] After the material is fed between two sets of packaging clamps 3, the drive shaft 20 drives the drive roller 2 to rotate via an external motor. The drive roller 2 can cause the material between the two sets of packaging clamps 3 to rotate and swing. When the material swings, the centrifugal force can press against the guide plate 8. When the sleeve 12 moves with the guide plate 8, it will stretch the second spring 26. After the guide plate 8 is reset and pulled by the characteristics of the second spring 26, the guide plate 8 will press against the material again. In this way, the guide plate 8 can reciprocate to press against the material, causing the material to swing back and forth. At the same time, multiple sets of flame heads 6 can calcine and heat the material, so that the swinging material is heated evenly and the material expansion quality is improved.
