Description

Technical Field

[0001] This utility model relates to the field of V-type air classifiers, and in particular to an energy-saving and consumption-reducing V-type air classifier. Background Technology

[0002] A V-type air classifier is a mechanical device used for powder classification, primarily in the cement, mineral powder, and chemical industries. Its core structure is a V-shaped classification chamber. By adjusting the airflow speed and the angle of the guide plates, centrifugal force and gravity are used to separate powders into coarse and fine particles. Fine powder is discharged and collected with the airflow, while coarse powder falls back for regrinding. This equipment features high classification efficiency, low energy consumption, and a compact structure, optimizing grinding system efficiency and improving finished product quality. It is suitable for closed-loop grinding systems and is one of the key pieces of equipment in modern dry powder processing.

[0003] While existing technologies can achieve certain powder separation in use, they have drawbacks: existing V-type cyclone separators suffer from material agglomeration and disordered airflow trajectory, resulting in excessive energy waste during separation and increased costs. In view of this, we propose an energy-saving and consumption-reducing V-type separator that solves the above problems. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an energy-saving and consumption-reducing V-type air classifier.

[0005] The technical solution of this utility model is as follows: an energy-saving and consumption-reducing V-type air classifier, comprising a box, a hopper, a guide plate, and a channel. The upper end of the box is provided with a hopper, and the hopper is provided with rotating columns with symmetrical design on both sides. The upper end of one side of the box is provided with an air inlet, and the upper end of the other side of the box is provided with an air outlet. The inside of the box is provided with a channel located on the side of the air inlet, and the channel is provided with a guide plate arranged in a linear array.

[0006] When using this device, the material to be screened enters the housing from the hopper. Inside the hopper, a rotating agitator is installed to break up the material, preventing large clumps from entering the housing and making screening impossible. It also prevents small particles from sticking together with large particles, which would result in poor screening and waste of resources. Gas enters from the air inlet and passes through a guide plate 1 inside the channel, ensuring a stable and unbiased airflow. The airflow then passes through guide plates 2 and 3, blowing small particles out of the air outlet and large particles out of the discharge outlet. Compared to previous devices, this device adds an airflow stabilizing guide device to the air inlet, making the airflow more stable. Stable airflow reduces the need for blower stabilization operations, reduces energy consumption, and has high practicality.

[0007] Preferably, the box body is provided with mounting seats on both sides, the lower end of the mounting seat is fixed with a bracket, and the lower end of the bracket is fixed with a base. The rigid connection between the mounting seat, the bracket, and the base enhances the overall stability of the equipment, reduces the interference of vibration on the screening process, and facilitates installation and transportation.

[0008] Preferably, the lower end of the box is provided with a discharge port, the number of channels is three, and a controller is provided on one side of the outer wall of the box. The three channels are designed to expand the airflow coverage and increase the screening capacity. The discharge port is separated from the airflow path to avoid mixing of large and small particles and ensure screening purity.

[0009] Preferably, a second gear is rotatably mounted on one side of the outer wall of the hopper, and a first gear is provided between the second gears. The first gear meshes with the first gear, and the first gear also meshes with the second gears on both sides. The meshing transmission of the first gear and the second gear enables the rotating column to rotate synchronously in opposite directions, so that the material is dispersed more evenly and blockage or wear caused by unilateral force is prevented.

[0010] Preferably, a mounting frame is fixed to one side of the outer wall of the hopper, and a motor is fixed to one side of the outer wall of the mounting frame. The output shaft of the motor is fixedly connected to the rotation center of one side of the gear. The motor drives the stirring frame through the gear set, which has high power transmission efficiency and low noise. The mounting frame fixes the position of the motor to avoid rotational deviation and ensures the continuity and reliability of the stirring action.

[0011] Preferably, the outer wall of the rotating column is provided with a stirring rack arranged in a linear array. The stirring racks on both sides are staggered. The linear array and staggered distribution of the stirring racks generate shear force, which efficiently breaks up agglomerated materials, while reducing dead corners and improving the uniformity of material flow in the hopper.

[0012] Preferably, the interior of the housing is provided with a second air guide plate arranged in a linear array below the air inlet. The second air guide plate performs secondary diversion and guidance of the airflow, balances the air pressure distribution inside the housing, and prevents local turbulence from affecting the separation accuracy of small particles.

[0013] Preferably, one side of the second guide plate is provided with a third guide plate arranged in a linear array. The third guide plate and the second guide plate work together to form a stepped airflow regulation, gradually refine the particle separation, and improve the collection efficiency of small particles at the air outlet.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model effectively breaks up material clumps and improves screening efficiency through the symmetrical rotating column and stirring frame design within the hopper. The cooperation between the air inlet and the first guide plate forms a stable airflow, reducing energy consumption and avoiding uneven screening caused by airflow turbulence. The second and third multi-stage guide plates further refine airflow control, ensuring precise separation of small particles and reducing resource waste.

[0016] II. Based on the first beneficial effect, this device achieves dual optimization of efficient material screening and energy saving through a symmetrical stirring mechanism within the hopper, a multi-channel airflow stabilization system, and a stepped guide plate design. The combination of gear transmission and motor drive ensures operational stability, while the staggered stirring rack and linear guide plate layout significantly improves crushing and separation accuracy, reduces energy consumption, and has high practicality.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The inside of the box 1 is provided with a channel 10 on the side of the air inlet 4, and the channel 10 is provided with a linear array of guide plates 9.

[0030] When using this device, the material to be screened enters the housing 1 from the hopper 3. Inside the hopper 3, there is a centrally rotating stirring rack 14 that can break up the material, preventing large clumps from entering the housing 1 and making them impossible to screen. It can also prevent small particles from sticking together with large particles, which would result in poor screening and waste of resources. Gas enters from the air inlet 4 and passes through the first guide plate 9 inside the channel 10, ensuring a stable and unbiased airflow. Then, the airflow passes through the second guide plate 11 and the third guide plate 13, blowing small particles out from the air outlet 2 and large particles out from the discharge outlet 12. Compared with previous devices, this device adds an airflow stabilizing and guiding device to the air inlet, which makes the airflow more stable. Stable airflow reduces the need for blower stabilization operations, reduces energy consumption, and has high practicality.

[0031] Example 2

[0033] The lower end of the box 1 is provided with a discharge port 12 and three channels 10. A controller 8 is provided on one side of the outer wall of the box 1.

Gear 1 17 meshes with gear 1 17 and gear 1 17 also meshes with gear 2 18 on both sides. The meshing transmission of gear 1 17 and gear 2 18 realizes the synchronous reverse rotation of rotating column 15, so that the material is more evenly dispersed and prevents blockage or wear caused by unilateral force.

[0035] A mounting bracket 16 is fixed to one side of the outer wall of the hopper 3, and a motor 19 is fixed to one side of the outer wall of the mounting bracket 16. The output shaft of the motor 19 is fixedly connected to the rotation center of one side of the gear 17. The motor 19 drives the mixing frame 14 through the gear set, which has high power transmission efficiency and low noise. The mounting bracket 16 fixes the position of the motor 19 to prevent it from shifting during operation and to ensure the continuity and reliability of the mixing action.

[0036] The outer wall of the rotating column 15 is provided with a stirring rack 14 arranged in a linear array. The stirring racks 14 on both sides are staggered. The linear array and staggered distribution of the stirring racks 14 form a shearing force, which efficiently breaks up agglomerated materials, while reducing dead corners and improving the uniformity of material flow in the hopper 3.

[0037] Inside the housing 1, below the air inlet 4, there is a linear array of guide plates 11.
