Description

Technical Field

[0001] This utility model relates to the field of cement production technology, specifically to a raw material feeding device for cement production. Background Technology

[0002] Cement is a powdered, hydraulic, inorganic binder. When mixed with water, it forms a paste that hardens in air or water, and effectively binds materials such as sand and stone together. Early mixtures of lime and volcanic ash were very similar to modern lime-volcanic ash cement. Concrete made from this cement, binding crushed stone, not only had high strength after hardening but also resisted erosion from fresh or salt water.

[0003] However, the feeding rate of existing cement raw material feeding equipment cannot be adjusted, which leads to cement accumulation after entering the roller pressing area. This not only affects the roller pressing effect of cement raw materials, but also makes it difficult to control the amount of material entering the mill, thus affecting subsequent cement processing. This utility model designs a raw material feeding device for cement production to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3 A raw material feeding device for cement production, comprising:

[0025] The machine consists of a base 1, a roller press body 2 fixedly connected to the top of the base 1, a feeding hopper 3 fixedly connected to the top of the roller press body 2, a material lifting mechanism 4 at one end of the roller press body 2, a feeding trough 5 at the top of the roller press body 2, a roller pressing chamber 6 inside the roller press body 2, a moving roller 7 and a fixed roller 22 rotatably connected to the inner cavity of the roller pressing chamber 6, a motor 8 fixedly connected to one side of the roller press body 2, an adjusting valve plate 9 through and inclinedly installed in the inner cavity of the feeding trough 5, a proximity switch 10 outside the adjusting valve plate 9, a conical distributing valve 11 fixedly connected to the bottom of the roller pressing chamber 6, a discharge pipe 12 fixedly connected to the bottom of the conical distributing valve 11, distributing ports 14 at both ends of the conical distributing valve 11, and inclined grooves 15 fixedly connected to the bottom of the distributing ports 14, and a dust collection mechanism outside the feeding hopper 3.

[0026] The inner cavity of the feeding hopper 3 is connected to the inner cavity of the feeding trough 5, and the inner cavity of the feeding trough 5 is connected to the roller pressing cavity 6.

[0027] Both the discharge pipe 12 and the inclined chute 15 penetrate the main body 2 of the roller press. The discharge pipe 12 and the inclined chute 15 are centrally symmetrical and face opposite directions.

[0028] Please refer to Figure 2 and Figure 3 The inner cavity of the cone-shaped material distribution valve 11 is fixedly connected with a guide ramp 13, and the inner cavity of the material distribution port 14 is fixedly connected with a guide ramp 16.

[0029] In this embodiment of the present invention, part of the material discharged from the roller pressing chamber 6 into the conical distribution valve 11 will be guided and converged by the first guide slope 13 and discharged into the discharge pipe 12 and then into the mill. The excess part will enter the two side distribution ports 14 and, guided and converged by the second guide slope 16, will enter the inclined trough 15 and then enter the material lifting mechanism 4 to be lifted back into the feed hopper 3 for re-rolling and processing, ensuring that the material can be smoothly discharged to the required position for the next processing and production stage.

[0030] Please refer to Figure 4 and Figure 5 The material lifting mechanism 4 includes a lifting and conveying housing 401 fixedly connected to the top of the base 1. A drive shaft 402 is rotatably connected to the inner cavity of the lifting and conveying housing 401. A spiral blade 403 is fixedly connected to the outer ring of the drive shaft 402. One end of the top of the lifting and conveying housing 401 is inclined and fixedly connected to a return pipe 404.

[0031] The return pipe 404 is connected to both the discharge bin 3 and the lifting and conveying housing 401. The inclined chute 15 is connected to the inner cavity of the lifting and conveying housing 401. A servo motor 405 is fixedly connected to the top of the lifting and conveying housing 401. The output shaft of the servo motor 405 is fixedly connected to the drive shaft 402.

[0032] In this embodiment of the present invention, excess cement material discharged through the feed inlet 14 will all enter the inclined chute 15 and be guided into the lifting and conveying housing 401. At this time, the servo motor 405 is turned on to drive the drive shaft 402 to rotate, which in turn drives the spiral blade 403 to rotate, thereby lifting the material discharged into the lifting and conveying housing 401 upward to be guided and conveyed back to the feed hopper 3 by the return pipe 404 for re-rolling and processing. This improves the rolling effect of the raw material feeding equipment for cement production on the material and ensures the quality of subsequent cement production.

[0033] Please refer to Figure 1 and Figure 4 The dust collection mechanism includes a U-shaped dust collection pipe 17 fixedly connected to the outer ring of the feeding hopper 3. A dust collection head 21 is fixedly connected to the inner ring of the U-shaped dust collection pipe 17. The dust collection head 21 communicates with the inner cavity of the feeding hopper 3. A connecting pipe 18 is fixedly connected to the bottom of the U-shaped dust collection pipe 17. A dust collection box 20 is fixedly connected to one side of the roller press body 2. A dust collection pump 19 is fixedly connected to the top of the dust collection box 20. The dust collection pump 19 is connected to both the connecting pipe 18 and the dust collection box 20.

[0034] In this embodiment of the present invention, dust is generated when cement raw materials are introduced into the feeding hopper 3 and when they are rolled in the roller pressing chamber 6. At this time, the dust pump 19 is turned on, and the connecting pipe 18 is used to create a negative pressure in the U-shaped dust suction pipe 17. The dust is sucked into the dust collection box 20 as much as possible using the dust suction head 21, thereby reducing the amount of cement raw material dust that spills out during the production process and reducing the impact on the health of production personnel and the environment.

[0035] When using this cement production raw material feeding equipment, while adding cement raw materials into the feeding hopper 3, the extension and retraction of the regulating valve plate 9 in the feed trough 5 is controlled according to the current of the roller press body 2 and in conjunction with the proximity switch 10. This controls the rate at which the raw materials are discharged into the roller pressing chamber 6. The cement raw materials guided by the regulating valve plate 9 enter the roller pressing area between the fixed roller 22 and the moving roller 7 in the roller pressing chamber 6. The moving roller 7 is driven by the motor 8 to roll the cement raw materials. After rolling, the material falls into the conical distributing valve 11, and then the flow is controlled according to the cement mill sound. The opening degree of the conical feed valve 11 is adjusted to regulate the amount of material entering the mill, which facilitates the control of the material discharge and the amount entering the mill, avoids the accumulation of cement raw materials, improves the rolling effect of cement raw materials, and ensures the smooth progress of subsequent cement production. A portion of the material discharged through the conical feed valve 11 is discharged through the discharge pipe 12 and enters the mill, while the excess material enters the inclined chute 15 through the feed ports 14 on both sides, and is then lifted back to the discharge bin 3 by the material lifting mechanism 4, and the above process is repeated continuously to process cement raw materials.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit, the scope of which is defined by the appended claims and their equivalents.
