Abstract
Description
Technical Field
[0001] This utility model relates to the field of air classifier technology, specifically to a V-shaped air classifier flow guide structure. Background Technology
[0002] The V-type classifier breaks up the finished material coming out of the roller press and then separates the qualified fine powder from the broken material. This is beneficial to the stable operation of the roller press, increases the system output, and also has a drying function.
[0003] The existing reference is Chinese utility model patent with announcement number CN201618692U, which discloses an adjustable guide plate for a V-type air classifier, which consists of a cylinder, a fixed guide plate, a rotating guide plate, an ear plate, an adjusting connecting rod, a clamping screw, a rotating shaft, a conical pin, a fixed plate, an adjusting plate, a guide key, a support cover, and a locking nut. Inside the classifier cylinder, a fixed guide plate and a rotating guide plate are connected. The rotating guide plate is connected to a rotating shaft via a conical pin. The rotating shaft is supported by a support cover on the side plate of the cylinder and a fixed plate. An adjusting plate is located on the outside of the fixed plate. The adjusting plate is connected to the rotating shaft by a guide key. The mating end faces of the fixed plate and the adjusting plate have the same radial tooth profile. Rotating the adjusting plate can adjust the rotating guide plate to the required working position. The position of the rotating guide plate is fixed by a locking nut. Above the rotating guide plate is a tie rod assembly consisting of an ear plate, an adjusting connecting rod, a clamping screw, and a nut, which reinforces the position of the rotating guide plate. The position of the rotating guide plate can be easily adjusted outside the cylinder, that is, the air volume passing through the guide plate can be adjusted to meet the requirements of different working conditions and achieve high-efficiency and high-quality classification.
[0004] The existing flow guiding structure has a fixed position of the flow guide plate during use, and the material will continuously fall into the fixed position of the air classifier. The material may accumulate in the fixed position and cause caking, which will affect the feeding of the air classifier. At the same time, the existing flow guide plate needs to limit the material discharge speed, and the material may block the top of the flow guide plate. Utility Model Content

The reducer is symmetrically installed on the left and right sides of the limiting tube with the center of the unloading shaft as the reference. The baffle can drive the material to rotate.
[0011] As a preferred embodiment of this utility model, the shaft of the drive motor is connected to the reducer, and the drive motor is fixedly connected to the limiting tube through a connecting frame; the drive motor can drive the reducer.
[0012] As a preferred technical solution of this utility model, the limiting bearing is symmetrically installed on the left side of the front and rear sides of the limiting tube with the center of the limiting tube as the reference, and the transmission shaft is rotatably connected to the limiting tube through the limiting bearing; the limiting bearing facilitates the rotation of the transmission shaft.

[0015] Compared with the prior art, this utility model provides a V-type air classifier flow guiding structure, which has the following beneficial effects:
[0016] 1. This utility model uses a limiting plate, the width of which is less than the width of the inner cavity of the limiting tube. The left end of the limiting plate has a chamfered structure and is fitted with the bottom surface of the guide plate. The limiting plate is rotatably connected to the limiting tube via a drive shaft, a limiting bearing, and a stepper motor symmetrically mounted at both ends of the drive shaft with the center as the reference. The stepper motor can drive the drive shaft to rotate the limiting plate clockwise and counterclockwise by the same angle, thereby adjusting the position of the end of the limiting plate. Under the action of the baffle, the material will fall above the guide plate and slide to the top of the limiting plate under the guidance of the guide plate, and finally slide down from the end of the limiting plate. This method can control the falling position of the material by rotating the limiting plate, avoiding the accumulation of material.
[0017] 2. This utility model, through the setting of the discharge shaft, forms a rotating connection between the discharge shaft and the limiting tube via a connecting bearing. The baffle is installed in a ring around the outside of the discharge shaft with the center as the reference, and the end of the baffle does not contact the wall of the limiting tube. The reducer is symmetrically installed on the left and right sides of the limiting tube with the center of the discharge shaft as the reference. The two ends of the discharge shaft are connected to the output end of the reducer. The reducer is driven by a drive motor, which drives the reducer to rotate the discharge shaft. When the discharge shaft rotates, the outer baffle will move the material, so that the material rotates from above to below the discharge shaft and slides down above the guide plate under the restriction of the baffle. This method can control the material discharge speed while avoiding material blockage at the top, thus preventing the material from entering the classifier normally. Attached Figure Description

[0027] The connecting bearing 11 is symmetrically installed on the left and right sides of the limiting tube 1 with the center of the limiting tube 1 as the reference. The unloading shaft 12 is rotatably connected to the limiting tube 1 through the connecting bearing 11. The baffle 13 is installed in a ring shape on the outside of the unloading shaft 12 with the center of the unloading shaft 12 as the reference, and the end of the baffle 13 does not contact the tube wall of the limiting tube 1.

[0029] A limiting bearing 2 is fitted inside the limiting tube 1. A drive shaft 21 is inserted inside the limiting bearing 2. A limiting plate 22 is inserted at the center of the drive shaft 21. A guide plate 23 is fixedly installed inside the limiting tube 1. Stepper motors 24 are fixedly installed at both ends of the drive shaft 21.
[0030] The limiting bearing 2 is symmetrically installed on the left side of the front and rear sides of the limiting tube 1 with the center of the limiting tube 1 as the reference. The transmission shaft 21 is rotatably connected to the limiting tube 1 through the limiting bearing 2. The width of the limiting plate 22 is smaller than the width of the inner cavity of the limiting tube 1. The left end of the limiting plate 22 is provided with a chamfer structure, and the left end of the limiting plate 22 is fitted with the bottom surface of the guide plate 23. The top surface of the guide plate 23 is a sloping structure. The rotating shaft of the stepper motor 24 is fixedly connected to the transmission shaft 21 by inserting it.

Under the action of the baffle 13, the material will fall above the guide plate 23 and slide above the limiting plate 22 under the guidance of the guide plate 23, and finally slide down from the end of the limiting plate 22. This method can control the position of the falling material by rotating the limiting plate 22, avoiding the accumulation of material.
