Description

Technical Field

[0001] The utility model relates to industrial furnace feeding equipment, in particular to a roasting furnace feeding device and, on this basis, also to a roasting system using the roasting furnace feeding device. Background Art

[0002] Calcination furnaces play a crucial role in industrial production, particularly in the preparation of molecular sieve catalysts. As crucial industrial equipment, calciners primarily calcine and modify the materials being processed at high temperatures to form the desired product. In molecular sieve catalyst production, dried molecular sieve catalyst particles are placed in a calciner, where they are calcined and modified at high temperatures to form the desired molecular sieve catalyst product.

[0003] Currently, roasting furnaces primarily operate by gravity-fed dry powdered material from a vertical cylinder above the roaster head into the furnace cavity. The material is then fed into the roasting cylinder through a chute inside the furnace head. The roaster's tilted design and the rotating cylinder drive the material through the high-temperature atmosphere to the furnace tail, where it is roasted. Because the roaster head cavity is fixed, this method of feeding the material into the furnace cylinder through the chute inside the furnace head prevents the material from being fed into the cylinder quickly and efficiently, causing it to accumulate and leak out. This requires operators to regularly clear the accumulated material and manually push it into the furnace barrel through the observation hole in the furnace head. Opening the observation hole reduces the negative pressure in the furnace and causes material to leak out, disrupting the production process and impacting worker health and the workplace environment. Existing powder feeding devices are complex to assemble and bulky, making them difficult to reliably install within the confined space of the roaster head and effectively feed the material into the furnace barrel, making it difficult to effectively address the problem of material accumulation at the furnace head.

[0004] For this reason, there is an urgent need for a roasting furnace feeding and propelling device that can be installed inside the roasting furnace burner head and that can deliver the material that falls into the burner head into the roasting furnace barrel without generating material accumulation at the burner head. Utility Model Content

The conveying module comprises a main shaft and a spiral blade. One end of the main shaft is located inside the roaster and the other end extends out of the roaster. The spiral blade is disposed on the portion of the main shaft located inside the roaster. The driving module is disposed outside the roaster and is in driving connection with the portion of the main shaft extending out of the roaster.

[0007] Preferably, a fixing plate is provided on the side wall of the roasting furnace, and the main shaft extends horizontally and extends through the fixing plate.

[0008] Preferably, the conveying module further comprises a sealing member, which is provided at a position of the main shaft passing through the fixing plate.

[0009] Preferably, the sealing member is an annular stuffing box provided between the fixed plate and the main shaft. When the main shaft is driven to rotate by the driving module, the main shaft and the stuffing in the sealing member are squeezed and rubbed to maintain the seal.

[0012] Preferably, the driving module includes at least one ratchet, a chain and a motor. The ratchet is fixed to the portion of the main shaft extending out of the roasting furnace, and the ratchet is connected to the motor through the chain.

[0013] Preferably, the driving module includes a coupling and a motor connected to the end of the main shaft extending out of the roasting furnace, and the motor is connected to the main shaft through the coupling.

[0027] The purpose of the utility model is to overcome the problem that the existing feeding device cannot be loaded into the roasting furnace, and the roasting furnace head has material accumulation, which requires regular cleaning.

[0028] In order to achieve the above-mentioned purpose, the present invention provides a roasting furnace feeding device, such as Figure 1 and Figure 2 As shown, it includes a conveying module 100 and a driving module 200. The conveying module 100 includes a main shaft 110 and a spiral blade 111. One end of the main shaft 110 is located inside the roasting furnace 1, and the other end extends out of the roasting furnace 1. The spiral blade 111 is arranged on the portion of the main shaft 110 located inside the roasting furnace 1. The driving module 200 is arranged outside the roasting furnace 1 and is in driving connection with the portion of the main shaft 110 extending out of the roasting furnace 1.

[0029] During the operation of the roasting furnace, the roasting furnace feeding device provided by the present invention is arranged in the furnace head of the roasting furnace 1, directly below the feeding position, wherein the main shaft 110 in the conveying module 100 rotates under the drive of the driving module 200, and the part of the main shaft 110 located inside the roasting furnace is provided with a spiral blade 111, which can transport the material falling thereon to the inside of the roasting furnace 1 when driven to rotate, thereby avoiding a large amount of material accumulation at the feeding position of the roasting furnace 1, that is, the furnace head position, and greatly reducing the frequency of cleaning the accumulated material in the furnace while improving the material utilization rate, thereby preventing harm to the staff and the working environment caused by cleaning the accumulated material in the furnace head of the roasting furnace 1.

[0030] Preferably, the spiral blade 111 is made from multiple circular rings. A straight line passing through the diameter of any one of the circular rings is cut, and the circular sheet is stretched with the cut edges as the ends. Several of the original sheets processed in this way are then joined end to end and welded to the main shaft 110 along their inner edges, thereby forming a spiral-shaped spiral blade 111 on the main shaft 110. The spiral blade 111 made from multiple circular rings can be adjusted in size by changing the size of the circular rings used to adapt to the requirements of different roasting furnaces 1 and different materials for the size of the spiral blade 111.

[0031] Preferably, if Figure 1 As shown, a fixing plate 11 is provided on the side wall of the roasting furnace 1, and a main shaft 110 extends horizontally and extends through the fixing plate 11. The fixing plate 11 fixes the main shaft 110 relative to the roasting furnace 1, and the portion of the main shaft 110 extending out of the roasting furnace 1 can be kept horizontal by the fixing plate 11, thereby ensuring that the main shaft remains horizontal during rotation, allowing the roasting furnace feeding device to function properly.

[0032] Preferably, the fixing plate 11 is detachably connected to the roasting furnace 1. By removing the fixing plate 11, it is convenient to inspect the interior of the roasting furnace 1 and replace its internal parts when it is shut down, and it is also convenient to disassemble and replace the main shaft 110 and other feeding devices of the roasting furnace.

[0033] Preferably, if Figure 1 As shown, the conveying module 100 further includes a seal 112, which is disposed at the position where the main shaft 110 passes through the fixed plate 11. The seal 112 ensures that there is no gap between the main shaft 110 and the fixed plate 11, thereby preventing the high-temperature gas and dust in the roasting furnace 1 from leaking out. While protecting the high-temperature atmosphere inside the roasting furnace 1 from the external environment, it also protects the personnel operating the roasting furnace 1 from being burned by the overflowing high-temperature gas and materials.

[0034] Preferably, the seal 112 is an annular stuffing box disposed between the fixed plate 11 and the main shaft 110. When the main shaft 110 is driven to rotate by the drive module 200, the main shaft 110 and the stuffing in the seal 112 are squeezed and rubbed to maintain a seal. By using the stuffing box, it is possible to squeeze and rub against the main shaft 110, ensuring that the sealing effect of the seal 112 is intact while ensuring that the main shaft 110 can rotate. By using the annular stuffing box, the appropriate stuffing can be selected according to the actual operating conditions of the roasting furnace 1 to achieve a good sealing effect. It also allows for quick and convenient replacement of the stuffing inside the main shaft 110 after disassembly.

[0035] Preferably, if Figure 1 and Figure 2 As shown, the end of the main shaft 110 extending from the roaster 1 is formed with a square cross-section to accommodate the connection of a crank. If material jams occur in the roaster's feeder, a crank can be connected to the end of the main shaft 110 to apply greater torque, thereby resolving the jam. This square cross-section also allows for the connection of a crank for manual cranking in the event of a failure of the drive module 200.

[0036] Preferably, if Figure 1As shown, the roasting furnace feeding device also includes a limiting module 300 arranged outside the roasting furnace 1. The limiting module 300 includes a base 301, at least one bearing seat 302 mounted on the base 301, and a bearing 303 mounted on the bearing seat 302. The bearing 303 is sleeved on the portion of the main shaft 110 extending out of the roasting furnace 1 to support the main shaft 110. The limiting module 300 can support and limit the portion of the main shaft 110 extending out of the roasting furnace 1, thereby ensuring that the portion of the main shaft 110 extending out of the roasting furnace 1 can remain horizontal and be driven to rotate on a horizontal plane, thereby ensuring that the roasting furnace feeding device can operate normally.

[0037] Preferably, if Figure 1 and Figure 2 As shown, the driving module 200 is mounted on a base 301. By being mounted on the base 301, the driving module 200 can keep its driving portion and the main shaft 110 on the same horizontal plane, thereby driving the main shaft 110 to rotate smoothly with less loss.

[0038] Preferably, if Figure 2 As shown, the drive module 200 includes at least one ratchet 201, a chain 202, and a motor 203. The ratchet 201 is fixed to the portion of the main shaft 110 extending out of the roasting furnace 1 and is in transmission connection with the motor 203 via the chain 202. Further preferably, a milled retaining ring groove and threads can be provided on the main shaft 110 to secure the ratchet 201. By driving the ratchet 201 fixed to the portion of the main shaft 110 extending out of the roasting furnace 1, the main shaft 110 can be driven to rotate, thereby driving the conveying module 100 to continuously and without material accumulation into the roasting area of ​​the roasting furnace 1 when the roasting furnace 1 is in operation. Furthermore, the ratchet 201 can rotate freely when the main shaft rotation speed exceeds that of the ratchet 201. This allows the main shaft 110 to be manually driven without being constrained by the chain 202 and motor 203 when the motor 203 is not used.

[0039] Preferably, the drive module 200 includes a coupling and a motor 203 connected to the end of the main shaft 110 extending from the roasting furnace 1. The motor 203 is connected to the main shaft 110 via the coupling. The motor 203 connected to the main shaft 110 via the coupling can drive the main shaft 110 to rotate, thereby driving the conveying module 100 to continuously and without accumulation of materials into the roasting area of ​​the roasting furnace 1 when the roasting furnace 1 is in operation.

[0040] Preferably, if Figure 1 and Figure 2As shown, the driving module 200 also includes a protective cover 204 mounted above it. The protective cover 204 can prevent the operator from coming into contact with the driving module 200 and causing personal injury, and can also ensure that the external environment does not affect the operation of the driving module 200, thereby ensuring the normal operation of the roasting furnace feeding system.

[0041] The second aspect of the present invention provides a roasting system, which includes a roasting furnace 1 and the above-mentioned roasting furnace feeding device, and the roasting furnace feeding device is arranged below the feed port of the roasting furnace 1. Through the roasting furnace feeding device arranged below the feed port, all materials entering the furnace head of the roasting furnace 1 fall on the conveying module 100 of the roasting furnace feeding device and are pushed into the roasting furnace 1 by the spiral blades 111 therein. Due to the spiral structure of the spiral blades 111, the materials that cannot be pushed into the roasting furnace 1 can be completely pushed into the furnace through multiple rotations, thereby avoiding the generation of material accumulation at the furnace head of the roasting furnace 1, improving the utilization rate of the materials in the furnace, reducing the frequency of cleaning the furnace head, and thus reducing the pollution of the roasting furnace 1 to the external environment while reducing the workload of the operators.

[0042] While the preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings, the present invention is not limited thereto. Within the technical concept of the present invention, various simple variations of the technical solution of the present invention may be made, including combining the specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple variations and combinations should also be considered as disclosed in the present invention and fall within the scope of protection of the present invention.
