Description

Technical Field

[0001] This utility model relates to the field of polyester material processing technology, and in particular to a high-temperature processing furnace with a uniform heating structure. Background Technology

[0002] A high-temperature treatment furnace for polyester materials is a device used for heat treatment of polyester materials. It provides a high-temperature environment through heating elements inside the furnace chamber, and hot air circulation is achieved with the help of baffles. This allows polyester chips or products to complete crystallization, drying or modification under the protection of inert gas. A precise temperature control system ensures temperature uniformity and improves the thermal stability and mechanical properties of the material. In order to facilitate the improvement of heating uniformity, a high-temperature treatment furnace with a uniform heating structure is required.

[0003] The high-temperature processing furnace with a uniform heating structure is a device designed by combining multiple sets of staggered heating tube arrays and honeycomb guide plates in the furnace chamber. The heating tubes adopt a combined heating method of radiation and convection, and the guide plates make the hot air flow form a three-dimensional circulating flow field. It is suitable for sintering and annealing of polyester and ceramic materials to improve heating uniformity and process stability.

[0004] Currently available high-temperature processing furnaces with uniform heating structures utilize spiral heating pipe networks and porous flow dividers. During operation, the pipe network radiates heat, and the flow dividers guide the hot airflow to ensure uniform three-dimensional heating of materials. To improve material pretreatment efficiency, existing technologies use grinding roller groups at the feed inlet to pre-cut lumpy materials. To ensure uniform feeding of the cut materials into the furnace, existing technologies use grinding rollers to pre-cut the materials during feeding to improve subsequent heating uniformity. However, this method cannot repeatedly cut insufficiently cut materials and uniformly feed the cut materials into the device, affecting the consistency of material density within the furnace and thus reducing the reliability of the device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0033] Reference Figure 2 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a high-temperature processing furnace with a uniform heating structure, including a heating cylinder 1, a heating ring 4 fixedly connected to the middle of the inner side of the heating cylinder 1, a grinding mechanism 2 provided at the top of the heating cylinder 1, the grinding mechanism 2 being used for pre-cutting during feeding, and a mixing mechanism 3 provided on the inner side of the heating cylinder 1, the mixing mechanism 3 being used to improve the heating uniformity.

[0034] The grinding mechanism 2 includes a feeding hood 21, which is connected to the top right side of the heating cylinder 1. Spring rods 22 are fixedly connected to all four sides of the inside of the feeding hood 21, and a filter screen 23 is fixedly connected to the top of each spring rod 22. Gears 24 are rotatably connected to the front and rear sides of the right side of the inner wall of the feeding hood 21. A grinding roller 25 is fixedly connected to the left side of the gear 24, and a top block 28 is fixedly connected to the left side of the grinding roller 25. A feeding assembly 26 is provided on the rear side of the inside of the feeding hood 21, and a sealing assembly is provided on the top of the feeding hood 21. 27; The feeding assembly 26 includes a rotating rod 261 and a conveyor belt 263. The two rotating rods 261 are rotatably connected to the upper and lower sides of the inner rear end of the feeding hood 21, respectively. The two rotating rods 261 are connected to each other by the conveyor belt 263. The transmission of the rotating rods 261 can drive the conveyor belt 263 to drive. A gear 262 is fixedly connected to the right side of the upper rotating rod 261. The gear 262 meshes with the rear gear 24. When the gear 24 is rotated, it can drive the gear 262 and the rotating rod 261 to rotate.

[0035] Specifically, when adding material to the heating cylinder 1 through the feeding hood 21, the rotating gear 24 drives the grinding roller 25 to rotate and pre-cut the material. At the same time, the rotation of the grinding roller 25 also drives the top block 28 to rotate synchronously. The top block 28 strikes the filter screen 23, and the elasticity of the spring rod 22 causes the cut material to vibrate on the filter screen 23, thereby achieving uniform feeding. Subsequently, because the conveyor belt 263 meshes with the gear 24, it drives the rotating rod 261 to rotate. The rotation of the rotating rod 261 drives the gear 262 on it to drive the transmission, thereby re-conveying the material to achieve multiple grinding.

[0036] Reference Figure 1 , Figure 3 and Figure 5 The mixing mechanism 3 includes a motor 31, which is fixedly connected to the left side of the heating cylinder 1. The output end of the motor 31 passes through the heating cylinder 1 and is fixedly connected to a rotating frame 34. Starting the motor 31 can drive the rotating frame 34 to rotate. A reciprocating rod 32 is rotatably connected to the inner center of the rotating frame 34. Slide grooves 35 are provided on both the upper and lower sides of the interior of the rotating frame 34. Mixing plates 33 are threadedly connected to the left and right sides of the exterior of the reciprocating rod 32. When the rotating frame 34 rotates, the mixing plates 33 will move left and right along the reciprocating rod 32. The mixing plates 33 are slidably connected to the slide grooves 35. The mixing plates 33 can move stably along the slide grooves 35 on the rotating frame 34. A counterweight assembly 36 is provided on the outer side of the reciprocating rod 32. An observation assembly 37 is provided on the front right side of the heating cylinder 1. A transmission assembly 38 is provided on the outer right side of the heating cylinder 1.

[0037] Specifically, when the motor 31 is turned on, the rotating frame 34 rotates accordingly. As the rotating frame 34 rotates, it meshes with the reciprocating rod 32 on the inner side. During the rotation of the rotating frame 34, it pushes the mixing plate 33 to move left and right along the slide groove 35. The movement of the mixing plate 33 can make the material in the heating cylinder 1 fully and evenly dispersed on the surface of the heating ring 4, which helps to improve the uniformity of material heating and heating efficiency.

[0038] Reference Figure 2 , Figure 3 and Figure 4 The sealing assembly 27 includes a movable door 271, which is located on the upper inside of the feeding cover 21. Hinges 272 are fixedly connected to the top left and right sides of the movable door 271, and the movable door 271 is rotatably connected to the feeding cover 21 through the hinges 272. The grinding mechanism 2 also includes a filter cover 29, which is fixedly connected to the lower inside of the feeding cover 21, and the upper side of the feeding cover 21 is fixedly connected to the spring rod 22.

[0039] Specifically, the hinge 272 can open and close the movable door 271 to allow material to be added to the device when the movable door 271 is opened and closed, while preventing external impurities from entering the device when the movable door 271 is closed. The filter cover 29 can further receive the material that has not been sufficiently ground on the missed side and facilitates its conveyor belt 263 to transport it.

[0040] Reference Figure 1 , Figure 2 and Figure 5 The transmission assembly 38 includes a transmission wheel 381 and a belt 382. The two transmission wheels 381 are respectively located on the right side of the heating cylinder 1 and the feeding hood 21. The right side of the front gear 24 passes through the feeding hood 21 and is fixedly connected to the upper transmission wheel 381. The right side of the reciprocating rod 32 passes through the heating cylinder 1 and is fixedly connected to the lower transmission wheel 381. Both transmission wheels 381 are connected by a belt 382. The transmission wheels 381 driven by the belt 382 can synchronously drive the front gear 24 to rotate when the reciprocating rod 32 rotates. The observation component 37 includes a positioning frame 371, which is located on the front right side of the heating cylinder 1. An observation window 372 is fixedly connected to the inner side of the positioning frame 371, allowing direct observation of the internal operation of the device. The counterweight component 36 includes a mounting block 361, which is fixedly connected to the middle of the outer side of the reciprocating rod 32. A counterweight 362 is fixedly connected to the bottom inner side of the mounting block 361. The counterweight 362 and the mounting block 361 ensure that the reciprocating rod 32 remains stationary when the rotating frame 34 rotates.

[0041] Specifically, the belt 382 drives the two transmission wheels 381 to rotate simultaneously, and as the transmission wheels 381 rotate, the front gear 24 and the reciprocating rod 32 can rotate simultaneously. The internal operation of the device can be observed through the observation window 372 inside the positioning frame 371, so as to facilitate timely operation. Through the mounting block 361 and the counterweight block 362 on it, the position of the reciprocating rod 32 can be kept unchanged during the operation of the device.

[0042] Working principle: Before using the device, when feeding material into the heating cylinder 1 through the feeding hood 21, the rotating gear 24 can drive the grinding roller 25 to rotate and perform preliminary pre-cutting of the material. At the same time, the rotation of the grinding roller 25 will also drive the top block 28 to rotate. Through the impact of the top block 28 on the filter screen 23 and the elasticity of the spring rod 22, the cut material can vibrate on it, so that it can be fed evenly. Then, through the meshing of the conveyor belt 263 and the gear 24, the rotating rod 261 can be driven to rotate. As the rotating rod 261 rotates, it drives the gear 262 on it to drive the material to be re-conveyed for multiple grinding.

[0043] Furthermore, starting the motor 31 can drive the rotating frame 34 to rotate. As the rotating frame 34 rotates and engages with the reciprocating rod 32 on its inner side, it can push the mixing plate 33 to move left and right along the slide groove 35 when the rotating frame 34 rotates, so that the material in the heating cylinder 1 is fully and evenly dispersed on the surface of the heating ring 4, so as to improve the heating uniformity and heating efficiency of the material.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
