Description
Technical Field
[0001] The present application relates to the technical field of atomizing discs, and in particular to a wear-resistant centrifugal atomizing disc. Background Art
[0002] At present, the bypass flue evaporation method has become the mainstream process for treating desulfurization wastewater from thermal power plants. The internal working conditions of the drying tower used in the bypass flue evaporation method are highly dusty, and a high-speed rotating centrifugal atomizer disk is usually required. However, during the use of the existing atomizer disk, it was found that the nozzle of the atomizer disk is easily worn. After the nozzle is worn, the atomization particle size of the atomizer disk will become larger, and the droplets will stick to the wall of the drying tower, resulting in the inability to put the desulfurization wastewater zero discharge system into operation.
[0003] Therefore, how to reduce the adverse effect of atomizer disk nozzle wear on its atomization effect has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0004] In order to reduce the adverse effect of atomizing disk nozzle wear on its atomization effect, the present application provides a wear-resistant centrifugal atomizing disk.
[0005] In order to achieve the purpose of the utility model, a wear-resistant centrifugal atomizing disc is provided, comprising:
[0006] housing and atomizing disc nozzles;
[0007] The side wall of the shell is suitable for connecting with the driving shaft of the driving device to rotate with the shaft. The shell is cylindrical, and the rotation axis of the shell coincides with the cylindrical axis of the shell. The cylindrical structure of the shell is provided with a first opening at one axial end for feeding, and the radial side wall of the cylindrical structure of the shell is provided with a discharge port. The feed end of the atomizing disk nozzle is connected with the internal cavity of the shell through the discharge port. The side wall of the feed end of the atomizing disk nozzle is detachably connected with the discharge port side wall of the shell, and the discharge end of the atomizing disk nozzle passes through the shell.
[0008] An outer wall of one end of the shell having the first opening is provided with a wear-resistant protrusion, and there are more than two wear-resistant protrusions, which are distributed circumferentially around the cylindrical axis of the shell.
[0009] Compared with the existing atomizer disc, the nozzle is fixedly connected to the discharge port of the shell and cannot be disassembled. After the nozzle is worn, the atomization particle size of the atomizer disc will become larger, and the droplets will stick to the wall of the drying tower, resulting in the inability to put the desulfurization wastewater zero discharge system into operation. In the wear-resistant centrifugal atomizer disc provided in the present application, the atomizer disc nozzle is detachably connected to the discharge port of the shell. After the atomizer disc nozzle is worn, it can be disassembled and replaced in time to ensure the atomization quality of the atomizer disc nozzle, such as the atomization particle size. By timely disassembling and replacing the worn parts, the influence of the atomizer disc nozzle wear on the atomization effect of the centrifugal atomizer disc is reduced. In addition, compared with the overall replacement of the centrifugal atomizer disc as a whole, the partial replacement of the atomizer disc nozzle, which is a wearable and lossy component, can save more operating and maintenance costs.

[0017] In addition, in order to better illustrate the present application, numerous specific details are given in the following specific embodiments. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, components and circuits well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.
[0018] The present application provides a wear-resistant centrifugal atomizing disk, comprising: a shell and an atomizing disk nozzle 400. The side wall of the shell is suitable for connecting with the driving shaft of the driving device to rotate with the shaft, the shell is cylindrical, the rotation axis of the shell coincides with the cylindrical axis of the shell, the cylindrical structure of the shell is provided with a first opening 110 at one axial end for feeding, the cylindrical structure of the shell is provided with a discharge port 210 at the radial side wall, the feed end of the atomizing disk nozzle 400 is connected with the internal cavity of the shell through the discharge port 210, the feed end side wall of the atomizing disk nozzle 400 is detachably connected with the discharge port 210 side wall of the shell, and the discharge end of the atomizing disk nozzle 400 passes through the shell; the outer wall of one end of the shell with the first opening 110 is provided with a wear-resistant protrusion 300, there are more than two wear-resistant protrusions 300, and the more than two wear-resistant protrusions 300 are distributed around the cylindrical axis of the shell.
[0019] The present application opens a first opening 110 in the housing, and the material to be atomized and sprayed enters the inner cavity of the housing through the first opening 110. The orientation during installation is adjusted so that the first opening 110 at one end of the housing rotation axis faces upward to prevent the material from flowing out. Driven by an external drive device, the housing and the material inside the housing rotate at high speed, and the material is sprayed out through the discharge port 210 on the axial side wall of the housing under the action of centrifugal force. The present application sets an atomizing disc nozzle 400 at the housing discharge port 210, and the material passing through at high speed is sprayed out in a mist form under the action of the atomizing disc nozzle 400.
[0020] Compared with the existing atomizer disc, the nozzle is fixedly connected to the discharge port 210 of the shell and cannot be disassembled. After the nozzle is worn, the atomization particle size of the atomizer disc will become larger, and the droplets will stick to the wall of the drying tower, resulting in the inability to put the desulfurization wastewater zero discharge system into operation. In the wear-resistant centrifugal atomizer disc provided in the present application, the atomizer disc nozzle 400 is detachably connected to the discharge port 210 of the shell. After the atomizer disc nozzle 400 is worn, it can be disassembled and replaced in time to ensure the atomization quality of the atomizer disc nozzle 400, such as the atomization particle size. By timely disassembling and replacing the wear parts, the influence of the wear of the atomizer disc nozzle 400 on the atomization effect of the centrifugal atomizer disc is reduced. In addition, compared with the overall replacement of the centrifugal atomizer disc as a whole, the partial replacement of the atomizer disc nozzle 400, which is a wearable and lossy component, can save more operation and maintenance costs.
[0021] In addition, during the use of the existing atomizer disc, the axial end of the housing with the first opening 110 is usually facing upward, and the upward end is arranged adjacent to the static side wall of the installation environment. The centrifugal atomizer disc rotates at high speed during the atomization process, and a slight imbalance may also cause the tilt vibration of the housing. Therefore, the upward end of the housing is prone to slight tilt and wear, and the accumulated wear after long-term use will aggravate the rotational imbalance of the centrifugal atomizer disc, which is dangerous. Therefore, the present application sets a wear-resistant protrusion 300 on the outer wall of this end of the housing, and uses the wear-resistant protrusion 300 to isolate the housing from the static side wall of the installation environment, reducing the risk of the housing being worn by contact with it, and the wear-resistant protrusion 300 is made of a material with good wear resistance, and even if it is worn, it is not easy to produce deformation loss, so as to maintain the balance of the wear-resistant centrifugal atomizer disc during high-speed rotation and ensure work safety.
[0022] In a possible implementation, the wear-resistant protrusion 300 is in the shape of a long strip, with one end of the wear-resistant protrusion 300 facing the cylindrical axis of the shell, and the other end of the wear-resistant protrusion 300 facing the cylindrical radial outer edge of the shell. The wear-resistant protrusion 300 is located on the circular radius of one axial end of the shell. The wear-resistant protrusion 300 is made of wear-resistant material and welded to the outer wall of one axial end (top end) of the shell.
[0023] In a possible implementation, a second opening 220 is provided on the side wall of one end of the housing away from the first opening 110, the first opening 110 and the second opening 220 are both circular holes, the first opening 110 and the second opening 220 are both coaxially arranged with the cylindrical cavity of the housing 200, the diameter of the first opening 110 is greater than the diameter of the second opening 220, the rotating shaft of the driving device is suitable for sequentially passing through the first opening 110 and the second opening 220 and connecting with the side wall of the housing 200, and the material is added to the cylindrical cavity of the housing 200 through the gap between the first opening 110 and the rotating shaft. Furthermore, a third sealing ring is provided on the inner wall of the second opening 220 to improve the sealing performance of the connection between the rotating shaft and the second opening 220.

[0026] In a possible implementation, a discharge end of the atomizing disk nozzle 400 protrudes out of a radial side wall of the cylindrical structure of the housing.
[0027] In a possible implementation, along the radial direction of the cylindrical structure of the shell, the discharge end of the atomizing disk nozzle 400 protrudes out of the side wall of the shell by a preset length A, and the preset length A is 5 to 10 mm, preferably 8 mm.

During the centrifugal atomization process of the wear-resistant centrifugal atomizing disc, the shell needs to rotate at a high speed, so the components of the shell must all consider the rotation balance to prevent the risk of falling off and vibration caused by imbalance and reduce the wear caused by imbalance and tilt. Therefore, more than two atomizing disc nozzles 400 should be consistent, the number of discharge ports 210 and atomizing disc nozzles 400 should be consistent and connected one by one, more than two atomizing disc nozzles 400 should be consistent, and the thread depth of more than two atomizing disc nozzles 400 should be consistent.

The outer wall on this side can be in the shape of a flat plate, with the second opening 220. It can also be provided with an outer convex arc surface 231 that matches the inner concave arc surface 231 of the truncated cone protrusion 230.
[0033] In a possible implementation, the cover 100 is fixedly connected to the open end of the housing 200 by bolts. A first sealing ring 410 is provided between the cover 100 and the open end of the housing 200, and the first sealing ring 410 is coaxially arranged with the cylindrical cavity of the housing 200, and the sealing performance between the cover 100 and the open end of the housing 200 is maintained by the first sealing ring 410.
