Description

Technical Field

[0001] The utility model relates to the technical field of cement production and processing equipment, in particular to a cement grinding device for cement production. Background Art

[0002] In the process of cement production, raw materials such as limestone, clay, and iron ore need to be ground to reach the fineness required for cement production. Through grinding, the performance of cement, such as strength, setting time, workability, etc., can be better controlled to meet different engineering and construction requirements. The cement grinding device is a key link in the cement production process, which directly affects the quality, production efficiency, and environmental impact of cement products.

[0003] After retrieval, the Chinese patent publication number: CN220803576U2 discloses a cement grinding device for cement production, which relates to the technical field of cement production equipment. The utility model includes a grinding table and grinding rollers. A cross frame is fixedly installed on the top surface of the grinding table. A driving component for driving the grinding rollers is arranged on the top surface of the cross frame. The rotating part of the driving component is rotatably installed with grinding rollers for grinding and crushing the cement in the grinding table. In this utility model, the vertical reciprocating vibration of the grinding rollers is achieved by the contact between the contact rod and the top surface of the annular undulating track under the elastic force of the spring. When the grinding rollers roll over the cement, the synchronous vibration improves the grinding efficiency of the cement. When the rotating part of the driving component and the grinding rollers rotate, the scraper is attached to the bottom of the grinding table through an elastic connecting piece to turn the cement inside the grinding table, and the bristles are used to clean the cement residues on the surface of the grinding rollers.

[0004] During the use of the above equipment, the vertical reciprocating vibration of the grinding rollers is achieved by the contact between the contact rod and the top surface of the annular undulating track under the elastic force of the spring.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0031] Refer to Figure 1 , Figure 2 and Figure 3 , an embodiment provided by the present invention: A cement grinding device for cement production, including a housing 1, a motor cover 2 is fixedly connected to the left side of the middle part of the front end of the housing 1, a fixed motor 3 is arranged inside the motor cover 2, an output end of the fixed motor 3 is fixedly connected to a first rotating shaft 4, a first crushing roller 5 is fixedly connected to the outer side of the middle part of the first rotating shaft 4, a plurality of uniformly distributed first crushing beads 6 are fixedly connected to the outer side of the first crushing roller 5, a main gear 7 is fixedly connected to the rear end of the middle part of the first crushing roller 5, a driven gear 8 is meshed and connected to the right end of the main gear 7, a second rotating shaft 10 is fixedly connected to the middle part of the driven gear 8, a second crushing roller 11 is fixedly connected to the outer side of the middle part of the second rotating shaft 10, a plurality of uniformly distributed second crushing beads 12 are fixedly connected to the outer side of the second crushing roller 11, and a transmission mechanism 9 is arranged at the front end of the second rotating shaft 10; a feeding pipe 13 is communicated with the middle part of the top end of the housing 1, and a feeding port 14 is communicated with the top end of the feeding pipe 13;

[0032] Specifically, on the outer side of the middle part of the first rotating shaft 4, a first crushing roller 5 is firmly fixed. The function of this first crushing roller 5 is to perform preliminary material crushing work to reduce the volume of the material and improve the subsequent processing efficiency. And around the first crushing roller 5, a ring structure composed of a plurality of first crushing beads 6 is cleverly fixed. These first crushing beads 6 are evenly distributed around it. When the material passes by, they will further refine and crush the material, so that the material can meet more refined particle size requirements. In addition, the equipment is also equipped with a second rotating shaft 10, and a second crushing roller 11 with a similar structural design is fixedly connected to the outer side of the middle part of it. The function of this second crushing roller 11 is similar to that of the first crushing roller 5. The whole equipment is surrounded by a tightly sealed casing 1 to prevent material leakage and at the same time protect the internal rotating shaft, crushing beads and other components from being affected by the external environment.

[0033] Referring to Figure 2 , Figure 3 and Figure 4 , the transmission mechanism 9 includes a first runner 901. The first runner 901 is fixedly connected to the front end of the second rotating shaft 10. A transmission belt 902 is rotatably connected to the outer side of the middle part of the first runner 901. The right end of the inner side wall of the transmission belt 902 is rotatably connected to a second runner 903. A connecting rod 904 is fixedly connected to the middle part of the second runner 903. The right end of the casing 1 is fixedly connected to an outer frame 905. The outer side wall of the connecting rod 904 is fixedly connected to an inner frame 906; a feed chute 22 is opened on the left side of the outer frame 905. A screening plate 23 is fixedly connected to the bottom end of the outer frame 905. A plurality of evenly distributed iron beads 24 are arranged inside the inner frame 906; two connecting plates 25 are fixedly connected to the right end of the outer frame 905. The bottom ends of the two connecting plates 25 are both fixedly connected to a first leg 26. Two connecting grooves 27 are opened on the left side of the bottom end of the casing 1. The bottom ends of the two connecting grooves 27 are both fixedly connected to a second leg 28. An observation window 29 is fixedly connected to the left side of the middle part of the casing 1. A control panel 30 is fixedly connected to the top left end of the casing 1. A protective shell 31 is hinged to the top end of the control panel 30;

[0034] Specifically, a feed chute 22 is opened on the left side of the outer frame 905. This design allows the material to smoothly enter the equipment. Further, a screening plate 23 is firmly connected to the bottom of the outer frame 905. This screening plate 23 plays an important role in screening and separating the material, ensuring that only the material meeting specific particle size requirements can enter the next process.

[0035] Referring to Figure 2 and Figure 4, a first installation groove 15 is provided on the left side of the front end of the inner side wall of the casing 1, and a second installation groove 16 is provided on the right side of the front end of the inner side wall of the casing 1; a rotating groove 17 is provided at the rear end of the middle part of the inner side wall of the casing 1, and a first bearing 18 is fixedly connected to the front end of the middle part of the first rotating shaft 4, and a second bearing 19 is fixedly connected to the front end of the middle part of the second rotating shaft 10; a first material guiding plate 20 is fixedly connected to the right side of the middle part of the front end of the inner side wall of the casing 1, and a second material guiding plate 21 is fixedly connected to the left side of the middle part of the front end of the inner side wall of the casing 1.

[0036] Specifically: in the middle of the front end of the inner side wall of the casing 1, the right side is firmly fixedly connected by the first material guiding plate 20, and on the left side, the second material guiding plate 21 is also fixedly connected to the middle of the front end of the inner side wall of the casing 1 in the same way. Such a design not only ensures the stability of the first material guiding plate 20 and the second material guiding plate 21, but also optimizes the guiding property of the material during the transmission process. The fixed connection of the first material guiding plate 20 and the second material guiding plate 21 provides a solid foundation for the operation of the entire machine, and at the same time improves the working efficiency and stability of the machine.

[0037] Working principle: When the device is needed to process cement blocks, in the middle of the top of the housing 1, a feed pipe 13 is designed. The function of this feed pipe 13 is to guide the material to smoothly enter the crushing area. The top of the feed pipe 13 is a circular feed inlet 14. The material is sent into the equipment through this feed inlet 14 to start its crushing journey. At the same time, the fixed motor 3 drives the first rotating shaft 4 to drive the first crushing roller 5 to rotate. At the same time, the main gear 7 fixed to the rear end of the first rotating shaft 4 drives the driven gear 8 to rotate, which can drive the second crushing roller 11 to rotate synchronously while the first crushing roller 5 rotates. The function of this first crushing roller 5 is to perform preliminary material crushing work to reduce the volume of the material and improve the subsequent processing efficiency. And around the first crushing roller 5, a ring structure composed of multiple first crushing beads 6 is cleverly fixed. These first crushing beads 6 are evenly distributed around it. When the material passes by, they will further refine and crush the material, so that the material can meet more refined particle size requirements. In addition, the equipment is also equipped with a second rotating shaft 10, and a second crushing roller 11 with a similar structural design is fixedly connected to the outside of the middle part of it. The function of this second crushing roller 11 is similar to that of the first crushing roller 5. At the same time, inside the inner frame 906, a plurality of iron beads 24 with uniform diameters are carefully arranged. These iron beads 24 are evenly distributed in the space of the inner frame 906. Their existence is crucial for the normal operation of the equipment and can provide necessary friction and rolling effects during the material screening process to enhance the screening effect. On the left middle part of the housing 1, an observation window 29 is carefully set. This observation window 29 allows the operator to directly observe the working state inside the equipment, so as to monitor the production in real time and discover problems in time. In addition, on the left top part of the housing 1, a control panel 30 is firmly fixedly connected. This control panel 30 is the operation center of the equipment, integrating various control functions such as start, stop, and adjustment, which is convenient for the operator to precisely control the equipment. In order to further ensure the safety of the operator and the protection of the equipment, a protective shell 31 is cleverly hinged on the top of the control panel 30. This protective shell 31 can effectively prevent accidental touching of the buttons or switches on the control panel 30, ensure the operation safety, and at the same time protect the control panel 30 from the invasion of the external environment such as dust and moisture, and maintain the long-term stable operation of the equipment.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
