Description
Technical Field
[0001] The utility model belongs to the technical field of cement clinker crushing, and in particular relates to a high-temperature clinker roller crusher. Background Art
[0002] The function of the high-temperature cement clinker roller crusher is to continuously crush the high-temperature cement clinker, decompose it into the required particle size, and achieve crushing and separation. During the crushing process of the high-temperature cement clinker, the crusher is cooled with a water cooling system. The water cooling system usually consists of water pipes, cooling water circulation devices, cooling water pools, etc. The cooling water flows through the hot spots of the crusher through the water pipes, taking away the heat, keeping the equipment within a suitable operating temperature range, and preventing the equipment from overheating or damage.
[0003] However, cement clinker crushers using traditional technology usually only use single-roll or double-roll crushing methods, which have poor crushing effects on materials and cannot achieve continuous and efficient crushing. Due to the low crushing efficiency, crushers using traditional technology need to consume more energy to complete the crushing task, resulting in unnecessary energy waste. Due to the poor crushing effect, crushers using traditional technology find it difficult to crush materials into particle sizes that meet the requirements. Crusher machines are usually not equipped with effective screening systems, resulting in the inability to timely and effectively screen the crushed materials, affecting product quality and production efficiency, resulting in a higher content of coarse aggregate in the product, affecting the quality of the finished cement product.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] The following is combined with Figure 1-4 To further explain this application in detail,
[0030] The embodiment of the present application discloses a high-temperature clinker roller crusher, including a tail roller crusher, the tail roller crusher includes a frame 1, a crushing chamber 2 is provided on the top of the frame 1, a pair of crushing rollers 3 rotating in opposite directions are rotatably provided in the crushing chamber 2, and a crushing tooth plate 4 is provided on the outer sides of the two crushing rollers 3 and penetrates the crushing chamber 2, and the cement clinker is continuously crushed by the cooperation of the two crushing rollers 3 and the cooperation of the crushing rollers 3 and the crushing tooth plate 4;
[0031] A reduction motor 13 is installed on both sides of the frame 1. The output shaft of the reduction motor 13 is connected to the input shaft of the crushing roller 3 through a pulley assembly 14. The reduction motor 13 is fixed on the reinforcing support plates 15 on both sides of the frame 1.
[0032] The output shaft of the reduction motor 13 is connected to the input shaft of the crushing roller 3 through the pulley assembly 14, thereby achieving efficient and smooth transmission and improving the overall working efficiency of the crusher. The reduction motor 13 is fixed on the reinforcing support plates 15 on both sides of the frame 1, thereby enhancing the stability of the entire crusher structure, allowing the equipment to remain stable during high-speed operation and reducing vibration and noise. The design of the pulley assembly 14 makes the connection between the crushing roller 3 and the reduction motor 13 relatively simple, making it more convenient to disassemble and replace parts, thereby helping to reduce maintenance costs. The reduction motor 13 is fixed on the reinforcing support plates 15, which can effectively prevent the motor from being displaced due to vibration and other reasons during operation, thereby improving the safety of the equipment.
[0033] The design of the pulley assembly 14 makes the overall structure of the crusher more compact, saves space, and is beneficial to equipment layout and installation. The transmission through the pulley assembly 14 reduces the wear of the direct connection between the reduction motor 13 and the crushing roller 3, thereby extending the service life of the equipment.
[0034] The top of the crushing chamber 2 is connected to a bucket-shaped feed inlet 16 .
[0035] In the tail roller crusher, the material enters the crushing chamber of the crushing bin 2 through the feed port 16. When encountering hard or unbreakable materials, the tail roller crusher has an automatic retreat function like the double-roll material crusher of traditional technology to avoid damage to the equipment.
[0036] The use of double rollers to continuously crush materials makes the crushing process more complete and improves the crushing efficiency. The tail roller crusher is a double roller crusher. Like the double roller material crushers on the market, it can adjust the roller gap and rotation speed, and can achieve precise control of the material particle size to meet the requirements of different uses. The clinker crushing particle size produced by this technical solution is less than or equal to 25 mm. The cement clinker is continuously crushed by the cooperation of two crushing rollers 3 and the cooperation of the crushing roller 3 and the crushing tooth plate 4. Compared with the traditional technology of only using double roller crushing or single roller crushing, it effectively improves the fine particle size activity effect and filling effect of the clinker, thereby improving the early strength and bonding performance of the cement product, and facilitating its crushing into the required particle size, with less large pieces of material. After crushing, the clinker particles with a particle size less than or equal to 25 mm reach 90%, thereby reducing the clinker particle size and improving the compressive strength of the product.
[0037] Two rectangular through-hole grooves 9 are symmetrically provided on both sides of the crushing bin 2, and a convex edge 10 extending outward is fixedly provided in the rectangular through-hole groove 9, and a plurality of mounting holes 11 are arranged at equal distances on the convex edge 10. The crushing tooth plate 4 is arranged through the rectangular through-hole groove 9 and waist hole grooves 12 corresponding to the mounting holes 11 are arranged at equal distances on the crushing tooth plate 4. The crushing tooth plate 4 is fixed to the convex edge 10 by bolts penetrating the waist hole groove 12 and the mounting holes 11.
[0038] The crushing tooth plate 4 is fixed on the convex edge 10 by bolts penetrating the waist hole groove 12 and the mounting hole 11, so the mounting position of the crushing tooth plate 4 is adjustable, so that the distance between the crushing tooth plate 4 and the crushing roller 3 is adjustable.
[0039] The spacing between the crushing tooth plate 4 and the crushing roller 3 can be achieved by adjusting the installation position of the crushing tooth plate 4 to meet the needs of different materials and crushing effects. The adjustable spacing between the crushing tooth plate 4 and the crushing roller 3 helps to optimize the crushing effect, reduce over-crushing, and make the product particle size more uniform. This design makes the crusher highly adaptable and can cope with production environments with different material characteristics and particle size requirements. On the premise of meeting the crushing effect, adjusting the spacing between the crushing tooth plate 4 and the crushing roller 3 helps to improve the crushing efficiency and reduce energy consumption. By reasonably adjusting the spacing between the crushing tooth plate 4 and the crushing roller 3, the wear of the material on the equipment can be reduced, thereby extending the service life of the equipment. The adjustable spacing between the crushing tooth plate 4 and the crushing roller 3 helps to prevent equipment overload and improve the safety of the equipment.
[0040] A dust cover 5 is fixedly provided on the inner side of the frame 1 and is docked with the discharge port 20 below the crushing bin 2. A vibrating feeder is docked at the bottom of the dust cover 5. The vibrating feeder includes an inclined screen bin 6. An inclined screen 7 is provided in the screen bin 6. The screen 7 is connected to a hard material discharge plate 8.
[0041] A pair of rollers rotating in opposite directions are used to crush the material under high pressure. Compared with traditional crushing technology, the tail roller crushing technology has the characteristics of higher crushing efficiency, energy saving and consumption reduction, uniform particle size, etc. The material is crushed by the extrusion and shearing action of the rollers on both sides and the crushing tooth plate 4. The crushed material is separated by the screen 7 on the vibrating feeder. The material that meets the predetermined particle size requirements falls naturally, while the hard or unbreakable material will automatically exit the crushing chamber through the screen 7 and the hard material discharge plate 8 to avoid damage to the equipment. Due to the use of double roller crushing, the impact and wear of the material during the crushing process are reduced, thereby reducing equipment wear and extending the service life of the equipment.
[0042] A vibration motor 17 is provided at the bottom of the screen bin 6, and a support leg 18 is also installed at the bottom of the screen bin 6. A cement clinker outlet 19 is provided on the screen bin 6 below the screen 7. High-frequency vibration of the screen 7 can be achieved, which effectively improves the screening efficiency, so that the material can pass through the screen 7 quickly and accurately. Through the vibration of the vibration motor 17, the material is effectively layered on the screen 7, and accurate particle separation is achieved. The cement clinker that meets the requirements is discharged from the cement clinker outlet 19 below the screen 7. The vibration of the vibration motor 17 helps prevent the screen hole from being blocked, improves the screening effect, and ensures the quality of the product.
[0043] The working principle of the high temperature clinker roller crusher is as follows:
[0044] 1. Material entry: Material enters the crushing bin 2 through the bucket-shaped feed port 16.
[0045] 2. Material crushing: In the crushing bin 2, the material is squeezed and sheared by a pair of crushing rollers 3 rotating in opposite directions, and at the same time is impacted and sheared by the crushing tooth plate 4, thereby achieving continuous crushing of the material.
[0046] 3. Material separation: After continuous crushing, the material is screened by the high-frequency vibration generated by the vibration motor 17. The material that meets the predetermined particle size requirements falls naturally, while the hard or unbreakable material will automatically exit the crushing chamber through the screen 7 and the hard material discharge plate 8 to avoid damage to the equipment.
[0047] 4. Material output: The screened material is discharged through the cement clinker outlet 19 below the screen 7 to achieve continuous material discharge.
[0048] Compared with traditional crushing technology, this technical solution has the characteristics of higher crushing efficiency, energy saving and consumption reduction, uniform particle size, etc. The design of fixing the reduction motor 13 on the reinforcing support plate 15 improves the stability of the equipment, reduces vibration and noise, and prevents displacement caused by vibration and other reasons during the operation of the motor, thereby improving the safety of the equipment. The high-temperature clinker roller crusher can effectively crush and separate materials through the high-pressure crushing, vibration screening and automatic retreat functions of the double roller wheels, meet the requirements of different particle sizes, and has the advantages of energy saving, high efficiency and safety.
[0049] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
