Description

Technical Field

[0001] This utility model relates to the field of air classifier technology, and in particular to a wear-resistant and high-efficiency air classifier. Background Technology

[0002] In the process of classifying powder materials such as cement and lime powder, in order to improve the uniformity and consistency of the powder materials, and also to remove impurities and unqualified particles from the powder materials, workers usually use high-efficiency air classifiers to classify the powder materials. Existing high-efficiency air classifiers are usually composed of a vertical cylinder, drive motor, rotor, feeding disc, air inlet pipe, fine powder discharge pipe and coarse powder discharge pipe.

[0003] For example, utility model application CN202021070162.X discloses a high-efficiency eddy current classifier, specifically including a shell, an air classification chamber, a fine powder collection pipe, and an outer pipe. A coarse powder collection chamber is fixedly installed on the bottom surface of the shell, and a feed pipe is fixedly installed on the top surface of the shell. A motor is fixedly installed on the top surface of the outer pipe, and a gear is fixedly sleeved at the output end of the motor. This utility model uses the motor to drive the gear to rotate, and the meshing of the gear and rack drives the baffle to move to the left, opening the top of the air inlet pipe. At this time, the air inlet pipe sends air into the inner cavity of the coarse powder collection chamber. Through the connecting pipe, the coarse powder in the coarse powder collection chamber is blown into the feed pipe. This achieves the goal of eliminating the need for manual operation during movement and preventing coarse powder from dispersing into the external environment, thus avoiding any impact on the operator's health and increasing the practicality of the device.

[0004] However, in the case of traditional high-efficiency air classifiers, a certain amount of dust and impurities will accumulate on the inner wall of the air inlet pipe during long-term operation. In order to prevent these dust and impurities from gradually increasing and clogging the air inlet pipe, the staff needs to clean the dust and impurities on the inner wall of the air inlet pipe regularly. The operation is relatively cumbersome and makes the labor intensity of the staff relatively high. Utility Model Content

[0005] In view of this, the present invention provides a wear-resistant and high-efficiency air classifier, which has a hollow cleaning frame that can automatically clean the dust and impurities accumulated on the inner wall of the air inlet pipe. During the airflow input process, the drive impeller is driven to rotate, the drive impeller is driven to rotate, the fixed shaft is driven to rotate, the fixed shaft is driven to rotate, the incomplete gear is driven to rotate, the incomplete gear is driven to move back and forth, the reciprocating gear is driven to move back and forth, and the connecting rod is driven to move back and forth. The reciprocating movement of the connecting rod causes the hollow cleaning frame to slide back and forth in the vortex air inlet pipe, thereby cleaning the deposits and agglomerates in the vortex air inlet pipe.

[0006] This utility model provides a wear-resistant and high-efficiency air classifier, specifically comprising: an air classifier cylinder; a feed pipe fixedly connected to the top surface of the air classifier cylinder; four fine powder discharge pipes fixedly connected in a ring array to the upper part of the air classifier cylinder; a vortex air inlet pipe fixedly connected to the lower part of the air classifier cylinder; a coarse powder discharge pipe fixedly connected to the bottom surface of the air classifier cylinder; a drive motor bolted to the center of the top surface of the air classifier cylinder; a drive shaft fixedly connected coaxially to the bottom surface of the drive motor shaft; a rotor fixedly connected to the outside of the drive shaft; the feed pipe and the rotor being aligned; a spreading disc provided at the lower part of the drive shaft; a ceramic sleeve fixedly connected to the top surface of the spreading disc; and four support columns fixedly connected in a ring array to the lower part of the air classifier cylinder.

[0007] Optionally, a guide rod is fixedly connected to the bottom end face of the spreading disc; a fixing frame is fixedly connected to the upper part of the powder selection cylinder; multiple sets of control protrusions are fixedly connected to the top surface of the fixing frame in a circular array; the multiple sets of control protrusions are all aligned with the position of the guide rod.

[0008] Optionally, a guide slide is fixedly connected to the top surface of the spreading disc; the guide slide is slidably connected inside the drive shaft; a fixing spring is fixedly connected to the top surface of the guide slide; and the end of the fixing spring is fixedly connected inside the drive shaft.

[0009] Optionally, a fixed rotating shaft is rotatably connected to the lower part of the powder classifier cylinder; a drive impeller is fixedly connected to the outside of the fixed rotating shaft; the drive impeller is aligned with the vortex air inlet pipe.

[0010] Optionally, two incomplete gears are symmetrically fixedly connected to the outside of the fixed rotating shaft; a reciprocating gear frame is provided on the outside of each of the two incomplete gears; the two reciprocating gear frames mesh with the two incomplete gears respectively.

[0011] Optionally, a connecting rod is fixedly connected to the left side of each of the two reciprocating gears; a hollow cleaning frame is fixedly connected to the end of each of the two connecting rods; the hollow cleaning frame has a U-shaped block structure; the hollow cleaning frame is slidably connected inside the vortex air inlet pipe. Beneficial effects

[0012] During the rotation of the spreading disc, the guide rod continuously contacts the control protrusion, causing the guide rod to drive the spreading disc to reciprocate up and down. This causes the material to vibrate on the spreading disc, accelerating the diffusion speed of the material in the classifier cylinder, improving the uniformity of material dispersion, and resulting in better separation of fine and coarse powders. This effectively improves the practicality of the high-efficiency classifier.

[0013] During the airflow input process, the drive impeller rotates, which in turn drives the fixed shaft to rotate. Subsequently, through a series of transmissions, the connecting rod drives the hollow cleaning frame to slide back and forth inside the vortex air inlet pipe, cleaning the deposits and clumps inside the vortex air inlet pipe and reducing the risk of blockage. At the same time, the sliding action of the sliding ring also helps to remove minor blockages that have already formed in the pipe, effectively improving the convenience of the high-efficiency air classifier and reducing the labor intensity of the workers.

[0028] A guide slide post 109 is fixedly connected to the top surface of the material spreading disc 111; the guide slide post 109 is slidably connected inside the drive shaft 107; a fixing spring 110 is fixedly connected to the top surface of the guide slide post 109; the end of the fixing spring 110 is fixedly connected inside the drive shaft 107.

[0029] A fixed rotating shaft 116 is rotatably connected to the lower part of the powder selection cylinder 1; a drive impeller 117 is fixedly connected to the outside of the fixed rotating shaft 116; the drive impeller 117 is aligned with the position of the vortex air inlet pipe 103.

[0030] Two incomplete gears 118 are symmetrically fixedly connected to the outside of the fixed rotating shaft 116; a reciprocating gear carrier 119 is provided on the outside of each of the two incomplete gears 118; the two reciprocating gear carriers 119 mesh with the two incomplete gears 118 respectively.

[0031] The specific usage and function of this embodiment are as follows: The support column 105 provides support for the powder-selecting cylinder 1. Material is fed into the powder-selecting cylinder 1 through the feed pipe 101. The drive motor 106 is started, causing the drive shaft 107 to rotate. During the rotation of the drive shaft 107, the rotor 108 rotates. The high-speed rotation of the rotor 108 evenly spreads the material onto the spreading disc 111, and the rotation of the spreading disc 111 disperses the material into the powder-selecting cylinder 1. The ceramic sleeve 112 increases the wear resistance of the spreading disc 111, making it less prone to wear. During the rotation of the spreading disc 111, the guide rod 113 rotates. The guide rod 113 continuously contacts the control protrusion 115 during rotation, causing the guide rod 113 to drive the spreading disc 111 to reciprocate, thus accelerating the process. The diffusion speed of the material in the powder classifier cylinder 1 is such that during the reciprocating lifting and lowering of the spreading disc 111, the guide slide column 109 slides within the drive shaft 107 and presses the fixed spring 110. The cooperation between the guide slide column 109 and the fixed spring 110 guides and resets the spreading disc 111. Airflow is input into the powder classifier cylinder 1 through the vortex air inlet pipe 103, causing the airflow to classify the material. Smaller fine powder particles are discharged through the fine powder outlet pipe 102, while larger coarse powder particles are discharged through the coarse powder outlet pipe 104. At the same time, during the airflow input, the drive impeller 117 is driven to rotate. During the rotation of the drive impeller 117, the fixed shaft 116 is driven to rotate. During the rotation of the fixed shaft 116, the incomplete gear 118 is driven to rotate. During the rotation of the incomplete gear 118, the reciprocating gear frame 119 is driven to move back and forth. Example 2:

[0032] Based on Example 1, please refer to Figures 3 to 4 It includes: a connecting rod 120 and a hollow cleaning frame 121. A connecting rod 120 is fixedly connected to the left side of each of the two reciprocating gear frames 119. A hollow cleaning frame 121 is fixedly connected to the end of each of the two connecting rods 120. The hollow cleaning frame 121 is a U-shaped block structure. The hollow cleaning frame 121 is slidably connected inside the vortex air inlet pipe 103.

[0033] The specific usage and function of this embodiment: During the reciprocating movement of the reciprocating gear 119, the connecting rod 120 will be driven to reciprocate. The reciprocating movement of the connecting rod 120 will drive the hollow cleaning frame 121 to slide back and forth in the vortex air inlet pipe 103, thereby cleaning the deposits and clumps in the vortex air inlet pipe 103.
