Description

Technical Field

[0001] This utility model relates to the field of manganese slag-based cementitious material preparation technology, specifically to a multi-stage heat treatment manganese slag-based cementitious material preparation device. Background Technology

[0002] Manganese slag-based cementitious materials often exist in powder or granular form. For example, manganese slag micronized powder can be used as an admixture in cement concrete. Its particle morphology may exhibit a glassy structure or crystalline mineral composition, such as magnesium feldspar and calcium aluminum silicate in ferrosilicon manganese slag. These materials can form auxiliary cementitious materials in composite systems (such as when mixed with sulfur-fixing ash or carbide slag). Their porous microstructure, with pore sizes distributed in the 10-100 nm range, helps to improve the density of concrete.

[0003] In most existing multi-stage heat treatment manganese slag-based cementitious material preparation devices, the manganese slag-based cementitious material is placed directly on the surface of a conveyor belt and transported to the drying oven for heating. However, placing the manganese slag-based cementitious material directly on the surface of the conveyor belt causes it to accumulate, which can easily lead to uneven drying results. Utility Model Content

[0004] The purpose of this invention is to address the problem that most existing multi-stage heat treatment manganese slag-based cementitious material preparation devices directly place the manganese slag-based cementitious material on the surface of a conveyor belt and transport it to the drying oven for heating. However, directly placing the manganese slag-based cementitious material on the conveyor belt causes it to accumulate, which easily leads to uneven drying. Therefore, this invention proposes a multi-stage heat treatment manganese slag-based cementitious material preparation device.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A multi-stage heat-treated manganese slag-based cementitious material preparation device includes a base frame, on which a conveyor belt and an open-bottomed drying oven are mounted. The drying oven is located above the conveyor belt, and a feeding mechanism is installed above the conveyor belt. A motor is installed on one side of the drying oven, and a bevel gear is fixedly mounted on the output end of the motor. A rotating shaft is rotatably mounted on one side of the drying oven, with a bevel gear meshing with the first bevel gear fixed at one end of the rotating shaft, and a fan blade located inside the drying oven fixed at the other end of the rotating shaft. A rotating shaft 1 is fixedly connected to one end of a bevel gear 2 that meshes with a bevel gear 3, and a turntable is fixed to the other end of the rotating shaft 1. A limit rod is fixed to one side of the turntable and is slidably connected to the feeding mechanism. A rotating shaft 4 is fixed to one side of the oven, and a bevel gear 4 that meshes with a bevel gear 3 is fixed to one end of the rotating shaft 4. A belt pulley 1 is fixed to the other end of the rotating shaft 4. A belt pulley 2 is fixed to the drive roller end of the conveyor belt, and a drive belt is frictionally connected between belt pulley 1 and belt pulley 2.

[0007] Preferably, the feeding mechanism is located on the feeding side of the oven.

[0008] Preferably, one end of the base frame is fixed with two symmetrically arranged side plates, and two sliding rods are fixedly mounted between the two side plates. The two sliding rods are arranged in parallel, and the unloading mechanism is slidably connected to the two sliding rods on one side and slidably connected to the limiting rod on the other side.

[0009] Preferably, the feeding mechanism includes a hopper, and a slider is provided on the side of the hopper near the sliding rod, the slider being slidably mounted on the two sliding rods.

[0010] Preferably, a limiting plate is fixed on one side of the hopper, a limiting groove is formed on one side of the limiting plate, and the limiting rod is slidably connected to the limiting groove.

[0011] Preferably, a crushing roller is rotatably mounted on the inner side of the hopper, and the crushing roller is located at the discharge port of the hopper.

[0012] Preferably, one end of the crushing roller is fixed with a second rotating shaft, one end of the second rotating shaft is fixed with a transmission gear, and a rack is also mounted between the two side plates, wherein the transmission gear and the rack mesh with each other.

[0013] Preferably, the top of the oven is also provided with a pair of support seats for supporting the rotating shaft.

[0014] Preferably, the top of the oven is also provided with a pair of support seats 2 for supporting the rotating shaft 4.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The motor drives bevel gear one to rotate, which in turn drives bevel gear three to rotate, which in turn drives bevel gear two to rotate, which in turn drives shaft one and turntable to rotate. The turntable then drives the limiting rod to slide repeatedly within the limiting groove, which in turn drives the limiting plate to slide repeatedly laterally. The limiting plate then drives the hopper to slide repeatedly laterally. This allows the manganese slag-based cementitious material to be evenly spread on the surface of the conveyor belt when it is placed on the conveyor belt, facilitating its drying.

[0017] 2. The motor, while driving the hopper to move laterally repeatedly for adjustment, also drives the transmission gear to move laterally repeatedly. This allows the transmission gear to rotate under the action of the rack, which in turn drives the second rotating shaft and the crushing roller to rotate. The rotation of the crushing roller crushes the manganese slag-based cementitious material, breaking down some of the solidified manganese slag-based cementitious material and preventing hopper blockage. At the same time, the third bevel gear drives the fourth bevel gear it meshes with to rotate, which in turn drives the fourth rotating shaft and the first belt pulley to rotate. The first belt pulley, under the action of the transmission belt, drives the second belt pulley to rotate, which in turn drives the conveyor belt to rotate. Thus, the motor can simultaneously drive the conveyor belt to transport the manganese slag-based cementitious material. Attached Figure Description

One end of the rotating shaft 6 is fixed with a bevel gear 7, and the other end of the rotating shaft 6 is fixed with a turntable 8. The bevel gear 5 forms a rotation adjustment structure through the motor 4. The rotating shaft 6, bevel gear 7, and turntable 8 all rotate synchronously. A limit rod 9 is fixed to one side of the turntable 8, and the limit rod 9 is slidably connected to the feeding mechanism. A feeding mechanism is provided on one side of the conveyor belt 2, located on the feeding side of the oven 3. A side plate 10 is fixed to one side of the conveyor belt 2, and a sliding rod 11 is fixed to one side of the side plate 10. Two sliding rods 11 are symmetrically arranged. A slider 12 slides on the outside of the sliding rod 11. The slider 12 is slidably installed on the outside of the two sliding rods 11. One side of the feeding mechanism is slidably connected to the two sliding rods 11, and the other side is slidably connected to the limit rod 9. The feeding mechanism includes a hopper 13, which is fixed to one side of the slider 12. A limiting plate 14 is fixed, and a limiting groove 15 is opened on one side of the limiting plate 14. The limiting rod 9 is slidably connected to the limiting groove 15. The feeding mechanism is used to pour the manganese slag-based cementitious material onto the surface of the conveyor belt 2. A rotating shaft 20 is rotatably mounted on one side of the oven 3. A bevel gear 21 is fixed at one end of the rotating shaft 20, and a fan blade 22 is fixed at the other end of the rotating shaft 20. The fan blade 22 can blow air into the oven 3 to circulate the air inside the oven 3 and improve the drying efficiency. A rotating shaft 23 is rotatably mounted on one side of the oven 3. A pair of support seats 2 are also provided on the top of the oven 3 to support the rotating shaft 23. A bevel gear 24 is fixed at one end of the rotating shaft 23, and a belt disc 25 is fixed at the other end of the rotating shaft 23. A belt disc 26 is fixed at the drive roller end of the conveyor belt 2. A drive belt 27 is frictionally connected between the belt disc 25 and the belt disc 26.

[0027] Motor 4 drives bevel gear 5 to rotate, which in turn drives bevel gear 21, which in turn drives bevel gear 7 and bevel gear 24, which in turn drive shaft 6 to rotate. Shaft 6 then drives turntable 8 to rotate, which in turn drives limit rod 9 to slide repeatedly within limit groove 15. Limit rod 9 then drives limit plate 14 to move laterally repeatedly, which in turn drives hopper 13 to move laterally repeatedly. This allows hopper 13 to evenly spread manganese slag-based cementitious material on the surface of conveyor belt 2, preventing the manganese slag-based cementitious material from accumulating on the surface of conveyor belt 2 and causing uneven drying.

[0028] Example 2

[0029] Please see Figures 1-4 As shown, a crushing roller 16 rotates inside the hopper 13. The crushing roller 16 is located at the discharge port of the hopper 13. A rotating shaft 17 is fixed to one end of the crushing roller 16, and a transmission gear 18 is fixed to one end of the rotating shaft 17. A rack 19 is fixed to one side of the side plate 10. The transmission gear 18 and the rack 19 mesh with each other. The hopper 13 simultaneously drives the transmission gear 18 to move repeatedly, so that the transmission gear 18 can rotate under the action of the meshing rack 19. This allows the transmission gear 18 to drive the rotating shaft 17 and the crushing roller 16 to rotate repeatedly. The repeated rotation of the crushing roller 16 can crush some of the solidified manganese slag-based cementitious materials, avoiding blockage of the hopper 13. The rotating shaft 20, bevel gear 21, and... The fan blades 22 rotate synchronously. Both bevel gear 1 5 and bevel gear 2 7 mesh with bevel gear 3 21. The rotating shaft 4 23 and bevel gear 4 24 rotate synchronously. Bevel gear 4 24 meshes with bevel gear 3 21. The rotating shaft 3 20 and rotating shaft 4 23 rotate synchronously. The belt disc 1 25 and belt disc 26 are connected by a transmission belt 27 to form a synchronous rotation structure. Bevel gear 4 24 can drive rotating shaft 4 23 to rotate, which in turn drives belt disc 1 25 to rotate. Belt disc 1 25 can then drive belt disc 26 to rotate under the action of belt disc 26, which in turn drives conveyor belt 2 to rotate, allowing conveyor belt 2 to transport manganese slag-based cementitious materials.

[0030] In use, this invention involves placing the manganese slag-based cementitious material into the hopper 13, controlling the motor 4 to drive the bevel gear 5 to rotate. The bevel gear 5 then drives the meshing bevel gear 21 to rotate, which in turn drives the meshing bevel gears 7 and 4 to rotate. The bevel gear 7 drives the rotating shaft 6 to rotate, which in turn drives the turntable 8 to rotate. The turntable 8 causes the limiting rod 9 to slide repeatedly within the limiting groove 15, allowing the limiting rod 9 to move laterally repeatedly. This, in turn, causes the limiting plate 14 to move laterally repeatedly, allowing the hopper 13 to evenly spread the manganese slag-based cementitious material onto the surface of the conveyor belt 2. Simultaneously, the hopper 13 drives the transmission gear 18 to move repeatedly, allowing the transmission gear 18 to mesh with the rack 19. Under the action of the transmission gear 18, the shaft 17 and the crushing roller 16 rotate repeatedly. The repeated rotation of the crushing roller 16 can crush some of the solidified manganese slag-based cementitious material, avoiding blockage of the hopper 13. At the same time, the bevel gear 24 can drive the shaft 23 to rotate, which in turn drives the belt pulley 25 to rotate. The belt pulley 25, under the action of the belt pulley 26, drives the conveyor belt 2 to rotate, which in turn transports the manganese slag-based cementitious material to the drying oven 3. The drying oven 3 then performs heat treatment on the manganese slag-based cementitious material. Meanwhile, the bevel gear 21 can drive the shaft 20 and the fan blade 22 to rotate, which blows air into the drying oven 3, improving air circulation and drying efficiency.
