Description

Technical Field

[0001] This utility model relates to the field of air classifier technology, and in particular to a cement air classifier with multi-stage dynamic sorting and intelligent control. Background Technology

[0002] A cement classifier is a device that uses aerodynamics to classify and screen cement particles by size during the cement processing, separating and collecting coarse and fine powder.

[0003] In the operation of existing cement classifiers, the dispersion of cement clinker mainly relies on the centrifugal action of the rotating spreading disc. Specifically, the rotating spreading disc throws cement clinker particles radially out through centrifugal force, causing them to initially disperse inside the classifier cylinder. However, as the particles hit the cylinder wall and fall at a loss of speed, the spreading disc continues to perform centrifugal throwing operations. The newly thrown particles and the already fallen particles are prone to forming small material agglomerates, affecting the classification effect. Summary of the Invention

[0004] In view of this, the purpose of this utility model is to propose a cement classifier with multi-stage dynamic sorting and intelligent control, so as to solve the problem that newly scattered particles and already decelerated falling particles are prone to forming small material agglomerates, which affect the classification effect.

[0005] To achieve the above objectives, this utility model provides a cement classifier with multi-stage dynamic sorting and intelligent control, including a tank body, and further comprising: a feeding assembly disposed at the top of the tank body, a coarse material outlet disposed at the bottom of the tank body, a fine material outlet disposed on the upper side of the tank body, an air inlet pipe disposed at the bottom of the tank body, and a sorting mechanism disposed on the tank body, wherein:

[0006] The sorting mechanism includes a slide rail disposed on the top of the tank, a slider passing through the slide rail and slidably connected to the slide rail, a rotating shaft passing through the slider and rotatably connected to the slider, a material spreading disc disposed in the middle of the rotating shaft, blades disposed at the bottom of the rotating shaft, a first drive mechanism for driving the rotating shaft to rotate, and a second drive mechanism for driving the slider to move up and down. When the material spreading disc spreads material, the second drive mechanism can simultaneously drive the material spreading disc to move upward.

[0007] Optionally, the feeding assembly includes a feeding pipe, a first valve connected in series within the feeding pipe, and a uniform plate disposed within the feeding pipe.

[0008] Optionally, the material leveling plate is snapped into the feed pipe, and the material leveling plate has a plurality of central through holes evenly distributed on it.

[0009] Optionally, the first drive mechanism includes a drive motor, a drive gear disposed on the drive motor, and a driven gear meshing with the drive gear, the driven gear being fixedly disposed on the top of the rotating shaft.

[0010] Optionally, the second driving mechanism includes a concave member disposed at the upper end of the slider, electric cylinders disposed at both ends of the concave member, and a drive motor mounted on the surface of the concave member.

[0011] The electric cylinder extends and retracts to drive the concave part to move vertically. The concave part drives the slider to rise and fall along the slide rail, thereby realizing the synchronous rise or fall of the spreading disc during the rotation process.

[0012] Optionally, the classifier further includes a circulation mechanism, which includes an auger assembly. The feed channel of the auger assembly is connected to the lower end of the tank, and the discharge channel of the auger assembly is connected to the feed pipe. A switch assembly is provided at one end of the feed channel. The switch assembly includes a second valve located at one end of the feed channel. When the second valve is in a vertical position, the coarse material outlet is open and the feed channel is closed. When the second valve is in a horizontal position, the coarse material outlet is closed and the feed channel is open.

[0013] When repeated sorting of coarse material is required, the second valve switches to a horizontal position, closing the coarse material outlet and opening the feed channel. The coarse material enters the auger assembly for cyclic sorting. The auger assembly extracts the coarse material from the bottom of the tank through the feed channel, and after being conveyed, returns to the feed pipe through the discharge channel, thereby improving the adequacy of sorting. When further sorting is not required, the second valve is in a vertical position, closing the feed channel and opening the coarse material outlet, allowing the coarse material to be discharged directly. In this embodiment, coarse material can be repeatedly sorted, improving the adequacy of sorting.

[0014] Optionally, the air inlet pipe is equipped with a filter screen, and the angle between the end of the air inlet pipe located inside the tank and the horizontal plane is designed to be acute.

[0015] When material enters the tank through the feeding assembly, the first drive mechanism drives the rotating shaft to rotate, causing the spreading disc to rotate at high speed. Under the action of centrifugal force, the material is evenly scattered into the tank. At the same time, the blades also rotate, generating an upward airflow that blows the fine material towards the fine material outlet. Simultaneously, the second drive mechanism pushes the slider to slowly rise along the slide rail, causing the spreading disc to achieve a spiral upward motion during rotation. This composite motion forms a three-dimensional sorting space, making it less likely for newly scattered particles and already decelerated falling particles to form small material agglomerates, thereby improving the powder sorting effect. When the predetermined height is reached, the feeding assembly is closed, and the second drive mechanism drives the spreading disc to move downward to the initial position to begin the next powder sorting operation.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0023] like Figure 1As shown, a multi-stage dynamic sorting and intelligent control cement classifier includes a tank 1, and further includes: a feeding assembly disposed at the top of the tank 1, a coarse material outlet 2 disposed at the bottom of the tank 1, a fine material outlet 3 disposed on one side above the tank 1, an air inlet pipe 4 disposed below the tank 1, and a sorting mechanism disposed on the tank 1, wherein:

[0024] The sorting mechanism includes a slide rail 5 disposed on the top of the tank 1, a slider 6 passing through the slide rail 5 and slidably connected to the slide rail 5, a rotating shaft 7 passing through the slider 6 and rotatably connected to the slider 6, a material spreading disc 8 disposed in the middle of the rotating shaft 7, a blade 9 disposed at the bottom of the rotating shaft 7, a first drive mechanism for driving the rotating shaft 7 to rotate, and a second drive mechanism for driving the slider 6 to move up and down. When the material spreading disc 8 spreads material, the second drive mechanism can simultaneously drive the material spreading disc 8 to move upward.

[0025] When material enters tank 1 through the feeding assembly, the first drive mechanism drives the rotating shaft 7 to rotate, causing the spreading disc 8 to rotate at high speed. Under the action of centrifugal force, the material is evenly scattered into the interior of tank 1. At the same time, the blades 9 also rotate, generating an upward airflow that blows the fine material towards the fine material outlet 3. Simultaneously, the second drive mechanism synchronously pushes the slider 6 to slowly rise along the slide rail 5, so that the spreading disc 8 achieves a spiral upward motion during rotation. This composite motion forms a three-dimensional sorting space, making it less likely for newly scattered particles and already decelerated falling particles to form small material agglomerates, thereby improving the powder sorting effect. When the predetermined height is reached, the feeding assembly is closed, and the second drive mechanism drives the spreading disc 8 to move downward to the initial position to start the next powder sorting operation.

[0026] like Figure 1 As shown, in some embodiments, the feeding assembly includes a feeding pipe 10, a first valve 11 connected in series within the feeding pipe 10 (the first valve 11 may be an electric butterfly valve), and a material distribution plate disposed within the feeding pipe 10. Optionally, the material distribution plate is snapped into the feeding pipe 10, and the material distribution plate has a plurality of centrally located through holes evenly distributed thereon. The material distribution plate forms a honeycomb-shaped flow guiding structure, so that the material is evenly dispersed onto the spreading disc 8.

[0027] like Figure 1 As shown, in some embodiments, the first drive mechanism includes a drive motor 12, a drive gear 13 disposed on the drive motor 12, and a driven gear 14 meshing with the drive gear 13, the driven gear 14 being fixedly disposed on the top of the rotating shaft 7.

[0028] When in operation, the drive motor 12 drives the drive gear 13 to rotate. The drive gear 13 drives the driven gear 14 to rotate through meshing. The driven gear 14 drives the rotating shaft 7 to rotate, thereby driving the spreading disc 8 and the blades 9 to rotate.

[0029] like Figure 1 As shown, in some embodiments, the second driving mechanism includes a concave member 15 disposed at the upper end of the slider 6, electric cylinders 16 disposed at both ends of the concave member 15, and a drive motor 12 mounted on the surface of the concave member 15. The electric cylinders 16 extend and retract to push the concave member 15 to move vertically, and the concave member 15 drives the slider 6 to rise and fall along the slide rail 5, thereby realizing the synchronous rise or fall of the spreading disc 8 during rotation.

[0030] like Figure 2 As shown, in some embodiments, the classifier further includes a circulation mechanism, which includes an auger assembly 17. The feed channel 18 of the auger assembly 17 is connected to the lower end of the tank 1, and the discharge channel 19 of the auger assembly 17 is connected to the feed pipe 10. A switch assembly is provided at one end of the feed channel 18. Optionally, the switch assembly includes a second valve 20 disposed at one end of the feed channel 18. When the second valve is in a vertical state, the coarse material outlet 2 is open and the feed channel 18 is closed. When the second valve 20 is in a horizontal state, the coarse material outlet 2 is closed and the feed channel 18 is open.

[0031] When repeated sorting of coarse material is required, the second valve 20 switches to a horizontal position, closing the coarse material outlet 2 and opening the feed channel 18. The coarse material enters the auger assembly 17 for cyclic sorting. The auger assembly 17 extracts the coarse material from the bottom of the tank 1 through the feed channel 18, and after being conveyed, returns to the feed pipe 10 through the discharge channel 19, thereby improving the adequacy of sorting. When further sorting is not required, the second valve 20 is in a vertical position, closing the feed channel 18 and opening the coarse material outlet 2, allowing the coarse material to be discharged directly. In this embodiment, the coarse material can be repeatedly sorted, improving the adequacy of sorting.

[0032] like Figure 1 As shown, in some embodiments, a filter screen is provided inside the air inlet pipe 4, and the angle between the end of the air inlet pipe 4 located inside the tank body 1 and the horizontal plane is designed to be acute. The filter screen can filter dust, and the acute angle design can reduce the adhesion of powder at the air inlet pipe 4.

[0033] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
