Description

Technical Field

[0001] This utility model relates to the field of centrifugal atomization technology, specifically a centrifugal atomizer with anti-clogging function. Background Technology

[0002] Centrifugal atomizers are devices that use the centrifugal force generated by a high-speed rotating disc to atomize liquid medicine. However, in actual use, the nozzles often become clogged due to impurities in the solution, coking caused by high temperatures, and other reasons, affecting the atomization effect and the normal operation of the equipment. Therefore, how to effectively prevent nozzle clogging has become an urgent problem to be solved in the field of centrifugal atomization technology. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a centrifugal atomizer with anti-clogging function, which also has cooling and coking dissolution functions, thus overcoming the shortcomings of existing technologies.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a centrifugal atomizer with anti-clogging function is provided, including a turntable, a slurry channel, a cooling system, and a control system. The cooling system includes a solvent supply system and a solvent input channel. The slurry channel and the solvent input pipe are arranged above the turntable and communicate with the turntable. The edge of the turntable is provided with a toothed structure and a nozzle. The control system is connected to the cooling system and the turntable.

[0005] The nozzle has a cooling channel inside, and the solvent input channel is connected to the cooling channel.

[0006] The cooling system is used to provide the cooling medium.

[0007] A drive shaft is provided in the middle of the turntable, and the drive shaft is connected to the control system. The control system is used to control the rotation speed of the turntable and the liquid inlet interval of the slurry channel and the cooling system. The liquid inlet times of the slurry channel and the cooling system are staggered.

[0008] In another embodiment, the cooling channel is disposed outside the nozzle for receiving solvent, and the wall of the cooling channel is perforated at a position opposite to the nozzle.

[0009] The above technical solution has the following beneficial effects:

[0010] 1) Anti-clogging function: By adding an auxiliary input pipe, the turntable and nozzle are flushed with a cleaning solution or a low-temperature solution, which effectively prevents blockage caused by impurity deposition and coking.

[0011] 2) Cooling effect: The nozzle is equipped with a cooling channel, and the cooling system provides circulating cooling medium to reduce the nozzle temperature, further preventing the dry blockage of the nozzle caused by the evaporation of water due to high temperature.

[0012] 3) Improved atomization efficiency: The toothed structure on the edge of the turntable and the optimized design of the nozzle enhance the atomization effect and improve the uniformity and fineness of the droplets. Attached Figure Description

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a mechanical connection or an electrical connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Example 1, refer to Figure 1 A centrifugal atomizer with anti-clogging function includes a turntable 2, a slurry channel 5, a cooling system, and a control system. The cooling system includes a solvent supply system and a solvent input channel for providing a cooling medium, which can be water or an organic solvent, for cooling the nozzle 1 and dissolving impurities deposited and coking on the nozzle 1.

[0020] The slurry channel 5 and the solvent input pipe are located above the turntable 2 and are connected to the turntable 2. The turntable 2 is provided with a toothed structure and a nozzle 1 on its edge. The toothed structure can enhance the atomization effect, and the nozzle 1 is used to further atomize the ejected solution.

[0021] The cooling system is connected to the solvent input pipeline. The nozzle 1 is equipped with a cooling channel 3. The solvent input channel is connected to the cooling channel 3. The nozzle temperature is reduced by circulating cooling medium to reduce coking and blockage of the slurry at the nozzle due to high temperature. The cooling medium can also dissolve the coking formed at the nozzle.

[0022] The turntable 2 is connected to the control system via the drive shaft 4. The control system is used to control the rotation speed of the turntable 2 and the liquid inlet interval between the slurry channel 5 and the cooling system, so that the liquid inlet time of the slurry channel and the cooling system is staggered. The slurry is first centrifuged and atomized, and then the cooling medium is introduced for cleaning. After cleaning, the slurry is introduced again for centrifugation and atomization, and then the cooling medium is introduced again for cleaning, and so on.

[0023] The specific process is as follows:

[0024] S1, the slurry enters the turntable from the slurry channel. The turntable rotates and causes the slurry to be thrown outward by centrifugal force. The slurry collides with the toothed structure on the edge of the nozzle and is atomized. The atomized droplets come into contact with the high-temperature gas, and the solvent in the droplets evaporates, forming small particles or powder. At this time, coking is also more likely to form in the nozzle and block the nozzle.

[0025] S2, the slurry supply stops, and the cooling medium enters the cooling channel from the solvent input pipe. The cooling medium cools the nozzle and dissolves the coke in the nozzle, thereby cleaning the nozzle.

[0026] S3, repeating S1 and S2.

[0027] Example 2, refer to Figure 2 The cooling channel 3 is located outside the nozzle and is used to receive the cooling medium. At the same time, the solvent input channel is located above the cooling channel. The cooling system supplies the cooling medium to the cooling channel through the solvent input channel. The cooling channel wall 31 and the outer wall of the nozzle form a narrow cooling channel 3. When the cooling medium enters the cooling channel 3, it adheres to the outer wall 11 of the nozzle and flows down naturally. When it passes through the nozzle 1, it dissolves the coke formed on the nozzle 1 and cools the nozzle 1. The cooling channel wall 31 in the cooling channel 3 is provided with a perforation 32, which can effectively prevent the droplets sprayed from the nozzle 1 during the atomization process from being blocked by the cooling channel wall 31. Other steps are the same as in Embodiment 1.

[0028] Although embodiments of the present invention have been shown and described, those skilled in the art should understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents. Improvements made without inventive effort should be included within the protection scope of the present invention.
