Description

Technical Field

[0001] This application relates to the field of cyclone technology, and more specifically, to a cyclone preheating and decomposition device. Background Technology

[0002] The cement mill cyclone separator is a key piece of equipment in a cement production line. Its main function is to separate and treat the dust and particulate matter generated inside the cement mill, thereby ensuring that the gas emitted into the atmosphere has a high degree of cleanliness. For example, Chinese Patent CN202420238855.7 discloses a cyclone preheating and decomposition device, which includes a cyclone separator body, an outlet pipe fixedly installed at the outlet end of the cyclone separator body, and also includes an interception box, a gathering cover, a circular block, a screen, a conical block, and a connecting pipe; the interception box is fixedly installed on top of the outlet pipe. The device comprises: a converging cover fixed to the top of the air outlet duct; a circular block whose outer ring wall is fixed in a circular hole by three connecting rods arranged in a ring array; three screens fixed in the circular holes between each pair of connecting rods; a conical block fixed to the bottom side of the circular block; and a connecting pipe fixed to the circular hole on the top side of the interception box. This invention has the advantage that the gas discharged from the air outlet duct and the converging cover diffuses around within the interception box after contacting the conical block, and then the dust particles intercepted by the screens fall into the interception box, without falling back down at the converging cover.

[0003] However, this existing technology has certain limitations in its use. When gas containing dust passes through the screen, some dust particles will gradually adhere to and accumulate on the surface of the screen. Over time, more and more dust accumulates in the pores of the screen, which will eventually cause the screen to be blocked by dust, thus affecting the normal flow of gas. Summary of the Invention

[0004] The purpose of this application is to provide a cyclone preheating and decomposition device, which can solve the technical problem that the prior art has limitations, where dust particles adhere and accumulate when dust-laden gas passes through a screen, clogging the screen over time and affecting gas flow.

[0005] This application provides a cyclone preheating and decomposition device, including a cyclone cylinder body, an air outlet pipe on the cyclone cylinder body, a filter box covered on the air outlet pipe, a filter screen embedded in the filter box, and a wind-driven component and a cleaning component rotatably disposed inside the filter box. The wind-driven component is located at the air outlet of the air outlet pipe, the cleaning component is in contact with the filter screen, and a transmission component is disposed between the wind-driven component and the cleaning component.

[0006] The transmission assembly includes a mounting plate, a first rotating rod, a second rotating rod, a first pulley, a second pulley, and a transmission belt. The mounting plate is fixedly installed inside the filter box. The first rotating rod and the second rotating rod are rotatably mounted on the mounting plate via bearings. The wind-driven component and the first pulley are fixedly connected to the first rotating rod. The cleaning component and the second pulley are fixedly connected to the second rotating rod. The first pulley and the second pulley are connected by the transmission belt.

[0007] The wind-driven component and the cleaning component are provided in multiple quantities, and the number of wind-driven components is the same as the number of cleaning components. The multiple cleaning components are evenly distributed on the filter screen.

[0008] The wind-driven component is a turbine, and the cleaning component is a cleaning brush rod.

[0009] A protective shell is fixedly installed on the mounting plate, and the first pulley, the second pulley, and the transmission belt are all located inside the protective shell.

[0010] The air outlet end of the air outlet pipe is fixedly equipped with a conical cover, and a conical block is fixedly equipped on the filter screen. The conical block corresponds to the opening end of the conical cover.

[0011] The filter box is equipped with a connecting pipe and a ash discharge pipe with a valve.

[0012] The beneficial effects of this utility model are:

[0013] This utility model provides a cyclone preheating and decomposition device. In use, the gas separated by the cyclone body flows into the filter box through the outlet pipe. After being filtered by the filter screen, the gas is discharged. The dust in the gas is intercepted by the filter screen. At the same time, when the gas is discharged from the outlet pipe, it impacts the wind-driven component, causing it to rotate. The wind-driven component drives the cleaning component to rotate through the transmission component. The cleaning component cleans the filter screen, and the removed dust falls to the bottom of the filter box. This device can effectively prevent the filter screen from being blocked by dust, maintain the filter screen's permeability, ensure normal gas flow, and achieve simultaneous filtration and cleaning without the need for downtime maintenance. In addition, it uses gas kinetic energy as a power source, eliminating the need for additional drive equipment. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0027] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to 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 application based on the specific circumstances.

[0031] like Figures 1 to 3 As shown, this application provides a cyclone preheating and decomposition device, including a cyclone body 1, an air outlet pipe 11 on the cyclone body 1, a filter box 2 covered on the air outlet pipe 11, a filter screen 21 embedded in the filter box 2, and a wind-driven component 3 and a cleaning component 4 rotatably arranged inside the filter box 2. The wind-driven component 3 is located at the air outlet of the air outlet pipe 11, the cleaning component 4 is in contact with the filter screen 21, and a transmission component 5 is arranged between the wind-driven component 3 and the cleaning component 4.

[0032] During use, the gas separated by the cyclone body 1 flows into the filter box 2 from the air outlet 11. After being filtered by the filter screen 21, the gas is discharged. The dust in the gas is intercepted by the filter screen 21. At the same time, when the gas is discharged from the air outlet 11, it impacts the wind drive component 3 and makes it rotate. The wind drive component 3 drives the cleaning component 4 to rotate through the transmission component 5. The cleaning component 4 cleans the filter screen 21 and the removed dust falls to the bottom of the filter box 2.

[0033] This device can effectively prevent the filter screen 21 from being clogged by dust, maintain the permeability of the filter screen 21, ensure the normal flow of gas, and achieve simultaneous filtration and cleaning without the need for downtime maintenance. In addition, it uses gas kinetic energy as a power source, eliminating the need for additional drive equipment.

[0034] like Figures 2 to 4 As shown, in this embodiment, the transmission assembly 5 includes a mounting plate 51, a first rotating rod 52, a second rotating rod 53, a first pulley 54, a second pulley 55, and a transmission belt 56. The mounting plate 51 is fixedly installed inside the filter box 2. The first rotating rod 52 and the second rotating rod 53 are rotatably mounted on the mounting plate 51 through bearings. The wind-driven component 3 and the first pulley 54 are fixedly connected to the first rotating rod 52. The cleaning component 4 and the second pulley 55 are fixedly connected to the second rotating rod 53. The first pulley 54 and the second pulley 55 are connected by the transmission belt 56.

[0035] When in use, the gas is discharged from the air outlet 11 and impacts the wind drive component 3, causing it to rotate. The wind drive component 3 drives the first rotating rod 52 to rotate, the first rotating rod 52 drives the first pulley 54 to rotate, the first pulley 54 drives the second pulley 55 to rotate through the transmission belt 56, the second pulley 55 drives the second rotating rod 53 to rotate, the second rotating rod 53 drives the cleaning component 4 to rotate, and the cleaning component 4 cleans the filter screen 21.

[0036] like Figure 2 and 3 As shown, in this embodiment, multiple wind-driven components 3 and cleaning components 4 are provided, and the number of wind-driven components 3 is the same as the number of cleaning components 4. Multiple cleaning components 4 are evenly distributed on the filter screen 21.

[0037] Multiple wind-driven components 3 and cleaning components 4 can expand the cleaning range and ensure uniform gas flow throughout the filter box 2.

[0038] like Figures 2 to 4 As shown, in this embodiment, the wind-driven component 3 is a turbine 31, and the cleaning component 4 is a cleaning brush 41. The turbine 31 serves as the wind-driven component 3. When dust-laden gas impacts the turbine 31, the turbine 31 utilizes the shape and structure of its blades to convert the kinetic energy of the gas into its own rotational kinetic energy, thereby achieving efficient rotation. The cleaning brush 41 serves as the cleaning component 4. Driven by the transmission component 5, its bristles are in close contact with the surface of the filter screen 21. During rotation, the bristles can penetrate deep into the pores of the filter screen 21 to clean out the dust adhering to the pores.

[0039] like Figures 2 to 4As shown, in this embodiment, a protective shell 57 is fixedly installed on the mounting plate 51. The first pulley 54, the second pulley 55, and the transmission belt 56 are all located inside the protective shell 57. The protective shell 57 can prevent dust from entering, avoid dust from interfering with and damaging the transmission component 5, improve the reliability and stability of the transmission component 5, and extend its service life.

[0040] like Figure 2 and 3 As shown, in this embodiment, a conical cover 12 is fixedly installed at the air outlet end of the air outlet pipe 11, and a conical block 22 is fixedly installed on the filter screen 21. The conical block 22 corresponds to the opening end of the conical cover 12.

[0041] In use, the gas separated by the cyclone body 1 flows into the filter box 2 from the outlet pipe 11. The conical shroud 12 at the outlet end of the outlet pipe 11 gathers the gas discharged from the outlet pipe 11 and discharges it. After the discharged gas comes into contact with the tip of the conical block 22, it diffuses around in the filter box 2. The gas is discharged after being filtered by the filter screen 21, and the dust in the gas is intercepted by the filter screen 21. In addition, the conical shroud 12 enables the gas discharged from the outlet pipe 11 to be directed more concentratedly towards the wind drive component 3, improving the rotation efficiency of the wind drive component 3. At the same time, the concave conical shroud 12 can also effectively prevent dust backflow. The conical block 22 can guide the airflow, making the airflow distribution in the filter box 2 more uniform, optimizing the airflow distribution in the filter box 2, and improving the filtration efficiency.

[0042] like Figure 2 As shown, in this embodiment, the filter box 2 is connected to a connecting pipe 23 and a ash discharge pipe 24 with a valve. In use, the gas is filtered by the filter screen 21 and discharged from the connecting pipe 23, flowing to the external environment or subsequent processing equipment. The ash discharge pipe 24 can be connected to an external dust collection device, which can periodically open the valve and suck out the dust particles in the filter box 2 to achieve the purpose of cleaning the ash accumulated in the filter box 2.

[0043] Working principle: When the cyclone preheating decomposition device provided in this application is in use, the gas separated by the cyclone body 1 flows into the filter box 2 from the air outlet pipe 11. The conical cover 12 set at the air outlet end of the air outlet pipe 11 gathers the gas discharged from the air outlet pipe 11 and discharges it together. After the discharged gas comes into contact with the tip of the conical block 22, it diffuses to the surroundings in the filter box 2. After being filtered by the filter screen 21, the gas is discharged from the connecting pipe 23. The dust in the gas is intercepted by the filter screen 21. At the same time, when the gas is discharged from the air outlet pipe 11, it impacts the turbine 31 and makes it rotate. The turbine 31 drives the first rotating rod 52 to rotate. The first rotating rod 52 drives the first pulley 54 to rotate. The first pulley 54 drives the second pulley 55 to rotate through the transmission belt 56. The second pulley 55 drives the second rotating rod 53 to rotate. The second rotating rod 53 drives the cleaning brush rod 41 to rotate. The cleaning brush rod 41 cleans the filter screen 21. The removed dust falls to the bottom of the filter box 2.

[0044] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
