Description

Technical Field

[0001] This utility model relates to the field of stator coating technology, and more specifically to a vibrating fluidized bed. Background Technology

[0002] In motor manufacturing, stator insulation coating is one of the key processes to ensure its electrical performance and service life. Common coating methods include immersion, spraying, and fluidized bed coating. Among these, fluidized bed coating technology is widely used in the powder coating process for the outer surface of stators due to its advantages such as uniform coating, strong adhesion, and high material utilization.

[0003] Traditional fluidized bed devices typically use a bottom air distribution plate to introduce compressed air, causing the coated powder to "boil" and form a fluid-like suspension. When the preheated stator is immersed in this fluidized zone, the powder can be adsorbed and initially coated onto its surface, subsequently solidifying at high temperature to form a dense insulating layer. However, in practical applications, traditional fluidized bed devices are static structures, unable to actively stir or disturb the powder, making it difficult to maintain a stable fluidized state over a long period.

[0004] Therefore, it is necessary to propose a vibrating fluidized bed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that traditional fluidizing tanks are static structures, which cannot actively stir or disturb powders and are difficult to maintain a stable fluidization state for a long time.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A vibrating fluidizing tank includes a fluidizing tank body, which is fixedly connected to a vibrating part via flange posts. The vibrating part includes a vibrator, an upper flange of the vibrator, and a lower flange of the vibrator. The upper flange and the lower flange of the vibrator are connected by a vibration spring, and the vibrator is fixedly connected to the bottom of the upper flange of the vibrator.

[0008] Furthermore, multiple spring bases are fixedly connected to the opposite side of the upper flange and lower flange of the vibrator, and the upper and lower ends of the vibration spring are sleeved on the spring bases.

[0009] Furthermore, the fluidizing tank body includes an air collecting plate fixedly connected to the upper end of the flange column, a fluidizing base fixedly connected to the upper end of the air collecting plate, and a fluidizing basin fixedly connected to the upper end of the fluidizing base. The bottom of the air collecting plate is provided with an air inlet hole for ventilation, and a fluidizing plate is fixedly installed inside the fluidizing base from top to bottom.

[0010] Furthermore, the number of fluidizing plates is two.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Please see Figures 1 to 3 A vibrating fluidized bed, comprising a vibrator and a fluidized bed body, for achieving uniform coating on the outer surface of a stator;

[0019] Vibration section: includes a lower flange 1 of the vibrator, a vibrator, an upper flange 3 of the vibrator, and multiple vibration springs 4; multiple vibration springs 4 arranged in a ring array are provided between the lower flange 1 and the upper flange 3 of the vibrator; multiple spring bases arranged in a ring array are fixedly installed on opposite sides of the upper flange 3 and the lower flange 1 of the vibrator, and the number is the same as that of the vibration springs 4; the two ends of the vibration springs 4 are respectively sleeved and abutted against the upper and lower spring bases 2 at corresponding positions; the vibrator is fixedly installed at the bottom of the upper flange 3 of the vibrator.

[0020] A flange post 10 is fixedly installed on the upper surface wall of the upper flange 3 of the vibrator, and the fluidizing tank body is fixedly installed on the top of the flange post 10.

[0021] Fluidized tank body: includes a gas collecting plate 5, an air inlet 6, a fluidized base 7, two fluidizing plates 8 and a fluidized basin 9; the gas collecting plate 5 is fixedly installed on the flange column 10, and the bottom of the gas collecting plate 5 is provided with a through air inlet 6 for ventilation; the fluidized base 7 is fixedly installed on the gas collecting plate 5, and two evenly distributed fluidizing plates 8 are fixedly installed inside the fluidized base 7 from top to bottom; the fluidized basin 9 is fixedly installed on the fluidized base 7.

[0022] Two fluidizing plates 8 are evenly installed from bottom to top on the fluidizing base 7. The fluidizing plates 8 have very small holes. The gas that passes through the air inlet 6 is gathered in the gas collecting plate 5. The gas that passes through the first fluidizing plate 8 evenly and then passes through the second fluidizing plate 8 greatly improves the fluidization effect of the coating powder in the fluidizing basin 9, so as to ensure that the copper wire at the end of the stator can be evenly coated with the coating powder.

[0023] Fluidization process:

[0024] First, an appropriate amount of coating powder is added to the fluidizing basin 9. Air is introduced through the air inlet 6 at the bottom of the air collecting plate 5. The gas enters the air collecting plate 5 and passes through the first fluidizing plate 8 at the bottom of the fluidizing base 7, so that the gas is evenly distributed on the first fluidizing plate 8. The evenly distributed gas then passes through the second fluidizing plate 8 of the fluidizing base 7, further fluidizing the coating powder in the fluidizing basin 9. At the same time, the vibration of the vibrator makes the fluidization height of the coating powder in the fluidizing basin 9 uniform. Then, the stator end (non-crown end) is inserted into the fluidizing basin 9 to achieve coating of the copper wire at the stator end. The vibrator, together with the vibration spring 4, achieves uniform vibration, ensuring that the coating powder can be evenly coated even in the small gaps of the copper wire.
