Description

Technical Field

[0001] The utility model relates to the technical field of Portland cement transportation, in particular to a clinker transportation device for Portland cement production. Background Art

[0002] During the growth process of silicate cement, it is necessary to transport the clinker with a temperature of 150°C to 200°C to the next process for processing through a conveying device. The existing conveying device, such as the cement clinker conveying device that is easy to tension disclosed in the Chinese patent application number 202021507465.3, belongs to the technical field of belt conveyors, which includes a support frame, and the support frame includes a first upper support beam and a first lower support beam arranged parallel to each other. Tensioning rollers are respectively provided at both ends of the support frame, and a conveyor belt is provided around the two tensioning rollers. One end of one of the tensioning rollers is equipped with an adjustment device that drives the tensioning roller to move along the length direction of the first upper support beam. The device drives the first slider to rotate by rotating the screw rod to realize the tensioning adjustment of the conveyor belt. However, when the clinker falls on the upper part of the conveying device, the impact force can easily cause the conveyor belt to be tightened. At the same time, when a part of the conveyor belt is stuck, the tensioning adjustment device of the device has no buffering function, which can easily cause the conveyor belt to be subjected to a large impact and be pulled apart. In addition, for some conveyor belts that need to climb slopes, a chain is provided at the bottom of the conveyor belt, and the power unit is connected to the chain through a sprocket to prevent slipping. However, the load on the sprocket is large, and the outer side of the sprocket is easily worn and needs to be replaced regularly. The existing sprockets are mostly one-piece structures, and can only be replaced as a whole after wear, and the replacement cost is high. Therefore, a clinker conveying device for silicate cement production is needed, and its tensioning adjustment device is provided with a spring buffer, which can retract when the conveyor belt is stuck to play a buffering role. At the same time, a new type of sprocket is used, and the tooth blocks can be replaced separately to reduce the use cost. Utility Model Content

[0023] like Figures 1 to 6 As shown, an embodiment of the present invention provides a clinker conveying device for silicate cement production, comprising: a frame 1, a conveyor belt 2, a head mechanism 4, and a tensioning adjustment mechanism 5. The frame 1 is installed on the ground, the head mechanism 4 is installed on the upper end of the frame 1, and the tensioning adjustment mechanism 5 is installed on the lower end of the frame 1. The conveyor belt 2 is arranged along the frame 1, and the two ends of the conveyor belt 2 are respectively wound around the head mechanism 4 and the tensioning adjustment mechanism 5; the tensioning adjustment mechanism 5 includes a tail sprocket 501, a guide rail 50 2. Slider 503, screw 504, guide rail 502 is installed on both sides of the lower end of frame 1, slider 503 is slidably installed on guide rail 502, both sides of tail sprocket 501 are connected to slider 503 through rotating shaft, one end of guide rail 502 is provided with stopper 505, one end of screw 504 is hinged to slider 503, the other end of screw 504 passes through stopper 505, an adjusting nut 506 is provided on screw 504, and a spring 507 is provided between adjusting nut 506 and stopper 505.

[0024] The feeding mechanism delivers the silicate cement clinker to the conveyor belt 2 at the lower end of the frame 1. Driven by the motor 403, the conveyor belt 2 moves upward along the frame 1, thereby driving the silicate cement clinker to move to the upper part of the frame 1, and then discharged into the head box 401, and introduced into the next process through the head box 401. When the conveyor belt 2 is in use, the length of the conveyor belt 2 will be slightly stretched. In order to ensure the smooth movement of the conveyor belt 2, the adjusting nut 506 can be adjusted at this time. After turning the adjusting nut 506, the degree of compression of the spring 507 can be adjusted. When the length of belt 2 changes, the tension of conveyor belt 2 can be adjusted. At the same time, when the feeding flow rate is large, the impact force on conveyor belt 2 is large, or conveyor belt 2 is stuck when running to a certain section. Under the pulling force of conveyor belt 2, slider 503 can overcome the elastic force of spring 507 and slide forward, playing a buffering role, reducing the impact force on conveyor belt 2. At the same time, a magnetic coupler 406 is provided between the motor 403 and the reducer 404. When conveyor belt 2 is stuck, it can run idle to avoid damage to components such as conveyor belt 2, motor 403, and reducer 404.

[0025] In a specific embodiment, Figure 4As shown, the screw 504 is parallel to the long direction of the guide rail 502. When the conveyor belt 2 is stuck, the conveyor belt 2 can drive the tail sprocket 501 and the slider 503 to slide on the guide rail 502, reducing the tension of the conveyor belt 2 and playing a buffering role.

[0026] In a specific embodiment, two adjusting nuts 506 are provided on the screw rod 504 , and the two adjusting nuts 506 are in close contact with each other. The two adjusting nuts 506 are in close contact with each other to prevent the adjusting nuts 506 from loosening, thereby ensuring that the spring 507 is in a compressed state.

[0027] In a preferred embodiment, Figure 2 、 Figure 3 As shown, the head mechanism 4 includes a head box 401, a driving sprocket 402, a motor 403, a reducer 404, and a main shaft 405. The head box 401 is installed at the upper end of the frame 1, and the main shaft 405 is installed in the head box 401 through a bearing seat. The driving sprocket 402 is installed on the main shaft 405. One end of the main shaft 405 passes through the head box 401 and is connected to the output shaft of the reducer 404. The motor 403 is connected to the input shaft of the reducer 404. The power of the motor 403 is transmitted to the main shaft 405 through the reducer 404, and then drives the driving sprocket 402 to rotate through the main shaft 405, thereby pulling the conveyor belt 2 to run on the frame 1.

[0028] In a specific embodiment, a magnetic coupling 406 is provided between the motor 403 and the input shaft of the reducer 404. The magnetic coupling 406 plays a protective role and can idle when the conveyor belt 2 is stuck to prevent the motor from burning. A coupling 407 is provided between the output shaft of the reducer 404 and the main shaft 405. When the reducer 404 and the main shaft 405 are offset, smooth transmission can be guaranteed.

[0029] In a specific embodiment, Figure 5As shown, the driving sprocket 402 and the tail sprocket 501 are both composed of a wheel body 6 and a tooth block 7. The wheel body 6 is provided with a positioning hole and a threaded hole, the inner side of the tooth block 7 is provided with a positioning protrusion 8, and the middle part of the tooth block 7 is provided with a step hole. The tooth block 7 is installed on the outside of the wheel body 6 through the positioning protrusion 8 and bolts. The tooth blocks 7 are spliced ​​together and surround the outer periphery of the wheel body 6. Since the conveyor belt 2 is loaded with a large load when transporting silicate cement clinker, the driving sprocket 402 and the tail sprocket 501 wear faster. After a period of use, when the driving sprocket 402 and the tail sprocket 501 need to be maintained, the bolts can be loosened, and then the tooth block 7 that needs to be replaced can be removed, and then the new tooth block 7 can be placed on the wheel body 6 so that the positioning protrusion 8 is inserted into the positioning hole, and then the bolts are tightened to complete the replacement. The positioning protrusion 8 and the positioning hole can realize the positioning of the tooth block 7, thereby improving the installation accuracy. When maintaining the driving sprocket 402 and the tail sprocket 501 , the tooth block 7 can be replaced separately without removing the wheel body 6 from the shaft body, thereby reducing maintenance costs and difficulty.

[0030] In a specific embodiment, Figure 6 As shown, a chain 9 is provided on the inner side of the conveyor belt 2, and the conveyor belt 2 is connected to the driving sprocket 402 and the tail sprocket 501 through the chain 9. The connection between the chain 9 and the sprocket is not easy to slip, which can ensure the smooth operation of the conveyor belt 2 when overloaded.

[0031] Of course, the present invention may have many other implementations. Based on this implementation, other implementations obtained by ordinary technicians in this field without any creative work are all within the scope of protection of the present invention.
