Description

Technical Field

[0001] This utility model relates to the field of cement production, and more specifically, to a decomposition furnace for cement production. Background Technology

[0002] A cement decomposition furnace is a device used to process waste cement and recycle its resources. It decomposes the organic matter and inorganic impurities in waste cement through high temperature and chemical reaction to produce reusable materials.

[0003] For example, the Chinese utility model patent with publication number CN221147183U has the advantages of uniform mixing and improved reaction efficiency. However, the driving component of its lower stirring structure is located inside the decomposition furnace, which makes it inconvenient to repair when a fault occurs. At the same time, the separate driving of the stirring structures on both sides helps to reduce production and manufacturing costs, but the energy consumption is high. In view of this, we propose a decomposition furnace for cement production. Utility Model Content

[0004] The purpose of this invention is to solve the current problems of BBB.

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a decomposition furnace for cement production, comprising a base plate. Two mounting plates are fixedly connected to the upper surface of the base plate, and a decomposition furnace is disposed between the two mounting plates. Two rotating shafts are fixedly connected to the surface of the decomposition furnace, and the two rotating shafts are rotatably connected to the two mounting plates respectively. A top cover is provided on the upper surface of the decomposition furnace, and a first stirring shaft is disposed on the top cover. The lower end of the first stirring shaft rotatably extends through the lower surface of the top cover. A second stirring shaft is rotatably sleeved inside the first stirring shaft. The upper and lower ends of the second stirring shaft extend out of the upper and lower surfaces of the first stirring shaft. Mounting discs are sleeved on the outer surfaces of both the first and second stirring shafts. Stirring rods are fixedly connected to both mounting discs, and the two sets of stirring rods are arranged in a mirror-like staggered manner. A stirring drive assembly is provided on the top cover.

[0006] As a preferred technical solution of this application, the stirring drive assembly includes a motor mounting plate, which is fixedly connected to the upper surface of the top cover. A motor is mounted on the motor mounting plate, and a first bevel gear is fixedly connected to the output end of the motor. The outer surfaces of the first stirring shaft and the second stirring shaft located on the upper side of the top cover are both fitted with second bevel gears.

[0007] As a preferred technical solution of this application, the two second bevel gears are mirror images of each other, and both second bevel gears are meshed with the first bevel gear.

[0008] As a preferred technical solution of this application, two uprights are fixedly connected to the upper surface of the top cover.

[0009] As a preferred technical solution of this application, the upper ends of the two uprights are fixedly connected to a support plate, and the upper end of the second stirring shaft is rotatably connected to the lower surface of the support plate.

[0010] As a preferred technical solution of this application, a first gear is sleeved on the outer surface of the rotating shaft on the left side, and a second gear is rotatably connected to the left side surface of the mounting plate on the left side.

[0011] As a preferred technical solution of this application, a support rod is fixedly connected to the left side surface of the mounting plate on the left side, a rotating seat is sleeved on the outer surface of the support rod, a hydraulic telescopic rod is fixedly connected to the upper side surface of the rotating seat, and a protrusion is fixedly connected to the eccentric part of the second gear.

[0012] As a preferred technical solution of this application, the outer surface of the protrusion is rotatably fitted with a rotating sleeve, and the output end of the hydraulic telescopic rod is fixedly connected to the rotating sleeve.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In the scheme of this application:

[0015] 1. By moving the drive assembly of the stirring rod to the top cover, the difficulty of maintenance can be reduced and the operating space can be increased. At the same time, a single drive source can be used in conjunction with a bevel gear to synchronously drive the first stirring shaft and the second stirring shaft to rotate in opposite directions, thereby reducing production costs and simultaneously achieving the goal of energy conservation.

[0016] 2. By replacing the direct-drive motor in the transmission structure with a hydraulic telescopic rod, the need for high torque demand is prevented from directly corresponding to an increase in motor power and size. To output sufficient torque, the motor rotor diameter and stator core length need to be increased simultaneously, resulting in a significant increase in overall size and weight. Simultaneously, the installation space also needs to be increased, increasing the overall load on the equipment. Attached Figure Description

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1

[0028] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A decomposition furnace for cement production includes a base plate 1. Two mounting plates 2 are fixedly connected to the upper surface of the base plate 1. A decomposition furnace 3 is disposed between the two mounting plates 2. Two rotating shafts 4 are fixedly connected to the surface of the decomposition furnace 3. The two rotating shafts 4 are rotatably connected to the two mounting plates 2 respectively. A top cover 5 is disposed on the upper surface of the decomposition furnace 3. A first stirring shaft 6 is disposed on the top cover 5. The lower end of the first stirring shaft 6 rotatably extends through the lower surface of the top cover 5. A second stirring shaft 7 is rotatably sleeved inside the first stirring shaft 6. The upper and lower ends of the second stirring shaft 7 extend out of the upper and lower surfaces of the first stirring shaft 6. Mounting discs 8 are sleeved on the outer surfaces of both the first stirring shaft 6 and the second stirring shaft 7. Stirring rods 9 are fixedly connected to both mounting discs 8. The two sets of stirring rods 9 are arranged in a mirror-like staggered manner. A stirring drive assembly is disposed on the top cover 5. Moving the drive assembly of the stirring rods 9 to the top cover 5 can reduce the difficulty of maintenance, increase the operating space, and at the same time, can use a single drive source to synchronously drive the two sets of stirring rods 9 to rotate, thereby reducing manufacturing costs.

[0029] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the stirring drive assembly includes a motor mounting plate 10, which is fixedly connected to the upper surface of the top cover 5. A motor 11 is mounted on the motor mounting plate 10, and a first bevel gear 12 is fixedly connected to the output end of the motor 11. A second bevel gear 13 is sleeved on the outer surface of the first stirring shaft 6 and the second stirring shaft 7 on the upper side of the top cover 5. The two second bevel gears 13 are mirror images of each other and are meshed with the first bevel gear 12. Two uprights 14 are fixedly connected to the upper surface of the top cover 5, and a support plate 15 is fixedly connected to the upper end of the two uprights 14. The upper end of the second stirring shaft 7 is rotatably connected to the lower surface of the support plate 15.

[0030] Example 2

[0031] The decomposition furnace for cement production provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a first gear 16 is fitted on the outer surface of the left rotating shaft 4, a second gear 17 is rotatably connected to the left side surface of the left mounting plate 2, a support rod 18 is fixedly connected to the left side surface of the left mounting plate 2, a rotating seat 19 is fitted on the outer surface of the support rod 18, a hydraulic telescopic rod 20 is fixedly connected to the upper side surface of the rotating seat 19, a protrusion 21 is fixedly connected to the eccentric part of the second gear 17, a rotating sleeve 22 is rotatably fitted on the outer surface of the protrusion 21, and the output end of the hydraulic telescopic rod 20 is fixedly connected to the rotating sleeve 22. The hydraulic telescopic rod 20 can replace the direct drive of the motor in the transmission structure, reducing the load and failure rate, and preventing the motor from failing due to overload caused by the heavy decomposition furnace.

[0032] Among them, a square tube can be set to extend the volume of the decomposition furnace, improve the combustion efficiency of fuel and the decomposition rate of raw materials, so that the decomposition furnace consumes less coal under the same output, and the two sets of stirring rods 9 have different overall diameters to avoid collisions between them when rotating.

[0033] The decomposition furnace for cement production provided by this utility model is used as follows:

[0034] The first bevel gear 12 is driven to rotate by the motor 11. Since the two second bevel gears 13 are meshed with the first bevel gear 12 and are mirror images of each other, they rotate in opposite directions. This rotation of the two bevel gears 13 drives the first stirring shaft 6 and the second stirring shaft 7 to rotate, respectively. The rotation of the first stirring shaft 6 and the second stirring shaft 7 drives the stirring rod 9 to rotate. At the same time, during discharge, the top cover 5 is removed first, and then the rotating sleeve 22 is moved by the hydraulic telescopic rod 20. Since the rotating sleeve 22 and the protrusion 21 are connected to the eccentric part of the second gear 17, the second gear 17 will rotate synchronously when the hydraulic telescopic rod 20 extends and retracts. The meshing of the second gear 17 with the first gear 16 drives the first gear 16 to rotate. Since the diameter of the second gear 17 is larger than that of the first gear 16, the hydraulic telescopic rod 20 can drive the decomposition furnace 3 to rotate at a large angle with a smaller distance.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; conversely, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model.
