Description

Technical Field

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

[0002] Cement grinding unit is one of the key equipment used in cement production, usually located at the end of cement production line. Its main function is to grind clinker (a semi-finished product formed by high-temperature calcination of raw materials such as limestone and clay) into cement powder. This process is also called cement grinding or finishing grinding.

[0003] After searching, a cement grinding device for cement production with announcement number CN219314838U includes: a processing box, the inner side and top of the processing box are respectively installed with a cement production grinding mechanism and a drying mechanism; the grinding mechanism includes a partition installed horizontally on the upper inner side of the processing box and evenly provided with leakage holes, and two transmission motors installed symmetrically on the top of the partition, and the output end of the transmission motor passes through the top of the partition and is connected to a grinding roller, a support shell is arranged on the outer side of the two grinding rollers, a filter is nested and installed at the bottom of the support shell, a linear reciprocating motor with an output end connected to the bottom of the filter is installed at the center of the inner bottom of the processing box, and the drying mechanism includes a mounting shell installed on the top of the processing box and a hot air blower installed on the outer wall of one side of the mounting shell. The cement grinding device for cement production can grind the clinker multiple times to make the grinding result more delicate and uniform, and can dry the clinker more comprehensively.

[0004] Based on the above patent, after the clinker is added to the inner side of the processing box, it will be immediately ground by two grinding rollers. After grinding, the clinker with qualified particle size will fall through the filter, and the rest will move up and down repeatedly with the supporting shell and be ground by the grinding rollers for many times until most of the clinker falls through the filter.

[0032] Embodiment 1: A cement grinding device for producing uniformly ground cement comprises a crushing bin 1, a first motor 2 is fixedly connected to the right end of the crushing bin 1, a first crushing wheel 3 is fixedly connected to the driving end of the first motor 2, the first crushing wheel 3 is connected to the second crushing wheel 4 through a transmission gear set, a grinding bin 5 is fixedly connected to the bottom end of the crushing bin 1 and penetrates through it, a second motor 6 is fixedly connected to the right end of the grinding bin 5, a transmission rod 8 is connected to the driving end of the second motor 6 through a grinding assembly, a support table 7 is connected to the discharging assembly at the bottom end of the grinding bin 5, a controller 10 is fixedly connected to the outer wall of the front end of the grinding bin 5, a first gear 9 is fixedly connected to the left end of the first crushing wheel 3 and a second gear 24 is fixed to the left end of the second crushing wheel 4, the first gear 9 and the second gear 24 are meshedly connected, the raw materials are put into the crushing bin 1 and the controller 10 is used to control the first motor 2 to start, so that the first motor 2 makes the first crushing wheel 3 rotate relatively with the cooperation of the first gear 9 and the second gear 24, so that the first crushing wheel 3 and the second crushing wheel 4 perform preliminary crushing.

[0033] Embodiment 2: The left end of the transmission rod 8 is fixedly connected to a reciprocating screw rod 11, and a slider 12 is installed on the outer wall of the reciprocating screw rod 11. The outer wall of the slider 12 is fixedly connected to a connecting plate 13. The four sides of the outer wall of the right end of the connecting plate 13 are fixedly connected to a plurality of pusher plates 14. When the pusher plates 14 move, the amplitude is not high and will not affect the rotation of the grinding rod 15. The driving end of the second motor 6 is connected to the grinding rod 15 through the grinding gear set. When the second motor 6 is started, the second motor 6 drives the main planetary gear 16 through the transmission rod 8 to make the auxiliary planetary gear 17 The grinding rod 15 is driven to rotate and grind the cement. When the transmission rod 8 rotates, it drives the reciprocating screw 11 to rotate, so that the reciprocating screw 11 drives the slider 12 to move back and forth along the inside thereof, so that the connecting plate 13 pushes the push plate 14, and the push plate 14 turns over the raw materials in the grinding bin 5, so that the cement is kept at the grinding rod 15, so that the cement can be fully ground, and the uniform and fine grinding can ensure a reasonable distribution of cement particle size, which helps to improve the strength and stability of the cement and ensure better construction performance and durability.

[0034] Embodiment 3: The discharging assembly includes a feed bin 18 fixedly connected to the top of the support platform 7, push plates 20 are slidably connected to the left and right sides of the rear end of the inner wall of the support platform 7 through a first spring 19, and movable plates 22 are slidably connected to the four sides of the bottom end of the inner wall of the support platform 7 through a second spring 21, and a material box 23 is installed on the top of the movable plate 22. After the cement is ground, it passes through the grinding bin 5 and falls into the material box 23 along the feed bin 18. The weight of the material box 23 gradually increases, so that the weight of the material box 23 exceeds the elastic force of the second spring 21, causing the movable plate 22 to move downward. When the material box 23 completely falls off from the feed bin 18, the elastic force of the first spring 19 pushes the push plate 20, so that the push plate 20 pops out the material box 23, thereby facilitating the removal of the ground cement, thereby reducing the loading and unloading time, thereby improving production efficiency, and completing production tasks faster.

The outer wall of the right end of the connecting plate 13 is slidably connected to the left end of the grinding bin 5 and penetrates through it. The rear end of the first spring 19 is respectively fixedly connected to the left and right sides of the rear end of the inner wall of the support platform 7, and the front end of the first spring 19 is respectively fixedly connected to the left and right sides of the rear end of the push plate 20.

When the material box 23 completely falls off from the feeding bin 18, the elastic force of the first spring 19 pushes the push plate 20, so that the push plate 20 ejects the material box 23.

[0036] Working principle: First, put the raw materials into the crushing bin 1, and use the controller 10 to control the first motor 2 to start, so that the first motor 2 makes the first crushing wheel 3 rotate relatively with the cooperation of the first gear 9 and the second gear 24, so that the first crushing wheel 3 and the second crushing wheel 4 perform preliminary crushing. When the second motor 6 is started, the second motor 6 drives the main planetary gear 16 through the transmission rod 8 to drive the secondary planetary gear 17 to drive the grinding rod 15 to rotate and grind the cement. When the transmission rod 8 rotates, it drives the reciprocating screw rod 11 to rotate, and the reciprocating screw rod 11 drives the slider 12 to move back and forth along the inside thereof, so that the connecting plate 13 pushes the push plate 14, and the push plate 14 turns the raw materials in the grinding bin 5, so that the cement is kept on the grinding rod 1 5, so that the cement can be fully ground, and the uniform and fine grinding can ensure that the cement particle size distribution is reasonable, which is helpful to improve the strength and stability of the cement, and ensure better construction performance and durability. After the cement is ground, it passes through the grinding bin 5 and falls into the material box 23 along the feeding bin 18. The weight of the material box 23 gradually increases, so that the weight of the material box 23 exceeds the elastic force of the second spring 21, so that the movable plate 22 moves downward. When the material box 23 is completely separated from the feeding bin 18, the elastic force of the first spring 19 pushes the push plate 20, so that the push plate 20 ejects the material box 23, thereby facilitating the removal of the ground cement, achieving the effect of reducing the loading and unloading time, thereby improving production efficiency, completing production tasks faster, and at the same time reducing the labor intensity of workers and reducing personal safety risks.
