[0028] As Figure 1As shown, the embodiment provides a fan impeller cleaning system, which comprises a cylinder 8, a fan 9, a cleaning assembly, an electric valve assembly and a controller. The cylinder 8 is used for the feeding and humidification treatment of tobacco leaves in the tobacco industry to meet the process requirements of subsequent processing. The fan 9 comprises an impeller, which can apply negative pressure to the cylinder 8 when rotating. When working in the cylinder 8, steam-like materials need to be fed by aeration, so exhaust relief equipment is also needed to remove excess steam and other gases for processing, and the removal of gases can be completed when the impeller rotates. The cleaning assembly is used to clean the cylinder 8 and the fan 9, and the cleaning assembly comprises a liquid supply device, a first liquid pipe and a second liquid pipe 3. The first liquid pipe is connected to the cylinder 8 and can communicate the cylinder 8 with the liquid supply device. The second liquid pipe 3 is connected to the fan 9 and can communicate the cylinder 9 with the liquid supply device. The liquid supply device can fill the first liquid pipe and the second liquid pipe 3 with cleaning liquid to clean dust, residual material liquid and the like at the cylinder 8 and the fan 9. The electric valve assembly is arranged in the second liquid pipe 3 and is used to control the on-off of the second liquid pipe 3. The controller is in communication connection with the liquid supply device and the electric valve. When the cylinder 8 and the fan work is completed and cleaning is performed, the liquid supply device starts to work and fills the first liquid pipe and the second liquid pipe 3 with cleaning liquid, and at this time the controller can control the electric valve assembly to make the second liquid pipe 3 communicate, so that the cleaning liquid can enter the fan 9 to clean the impeller.

[0029] When the cylinder 8 and the fan 9 production is completed and the equipment enters the cleaning stage, the liquid supply device supplies liquid to the first liquid pipe. The controller can obtain the working information of the liquid supply device and control the electric valve assembly to make the second liquid pipe 3 communicate or make the second liquid pipe 3 be blocked. That is, the above-mentioned fan impeller cleaning system can automatically open the second liquid pipe 3 to clean the impeller of the fan 9 when the cylinder 8 enters the cleaning stage and the liquid supply device supplies liquid to the first liquid pipe, which avoids manual operation, and can also automatically block the second liquid pipe 3 after cleaning is completed, which avoids the exhaust gas at the fan 9 from entering the liquid supply device and ensures the cleanliness in the liquid supply device.

[0030] Further, in the embodiment, the liquid supply device can be a water pump, a water tank and the like, and the cleaning liquid can be clean water or a mixed liquid with a cleaning agent, which is not limited in the embodiment.

[0031] Specifically, in the embodiment, the electric valve assembly includes an electromagnetic valve 7 and a pneumatic two-way ball valve 2, the controller is in communication connection with the electromagnetic valve 7, a compressed gas pipe 6 is arranged between the electromagnetic valve 7 and the pneumatic two-way ball valve 2, the electromagnetic valve 7 can control the on-off of the compressed gas pipe 6, and the on-off of the compressed gas pipe 6 can control the pneumatic two-way ball valve 2 to block the second liquid pipe 3 or make the second liquid pipe 3 communicate. When the roller 8 and the fan 9 complete the production work and enter the cleaning stage, the controller sends a control signal to the electromagnetic valve 7, the electromagnetic valve 7 makes the compressed gas pipe 6 open, so that the compressed gas pipe 6 is filled with compressed gas, and the kinetic energy of the compressed gas drives the pneumatic two-way ball valve 2 to rotate, so that the second liquid pipe 3 is in a communication state. After cleaning, the controller controls the electromagnetic valve 7 to change the state of the pneumatic two-way ball valve 2, so that the pneumatic two-way ball valve 2 blocks the second liquid pipe 3. In addition, the pneumatic two-way ball valve 2 adopts a pneumatic actuator, has good self-lubricating property, and the cleaning frequency of the roller 8 and the fan 9 is high. Long-term use of the electronic valve and the pneumatic two-way ball valve 2 can make the fan impeller cleaning system have good wear resistance and stability.

[0032] Specifically, in the embodiment, the second liquid pipe 3 is provided with a cleaning nozzle 1 at one end close to the fan 9, and the liquid outlet direction of the cleaning nozzle 1 is towards the impeller. The cleaning nozzle 1 can disperse the liquid column into a spraying surface when the cleaning liquid passes through, and the spraying surface can fully contact and clean the impeller.

[0033] Further, in the embodiment, the fan 9 includes a shell, the cleaning nozzle 1 is located at the top of the shell, and the liquid outlet direction of the cleaning nozzle 1 is downward. When the cleaning liquid cleans the impeller, the liquid can flush the impurities away from the impeller, and then the impurities will flow down with the liquid. The upward and downward spraying can make the upper part of the impeller be cleaned first, and the cleaning liquid flows from top to bottom under the action of gravity to realize the complete cleaning of the impeller, so as to ensure the cleaning effect of the impeller.

[0034] Further, in the embodiment, the shell side wall is connected with a moisture discharge pipeline 12 and an exhaust pipeline 10, the moisture discharge pipeline 12 is used to communicate with the drum 8, and the exhaust pipeline 10 is used to communicate with the gas treatment device. It can be understood that the fan 9 is always kept in communication with the drum 8, so as to apply negative pressure to the drum 8 by the fan 9 and to remove the excess steam and other gas in the drum 8. The moisture discharge cover 11 and the moisture discharge pipeline 12 need to be arranged between the drum 8 and the fan 9 to realize the moisture discharge function of the fan 9. After the steam and other gas are sucked into the fan 9 shell by the fan 9, the gas needs to be discharged into the gas treatment device through the exhaust pipeline 10. The gas treatment device will treat the gas, and the treated gas can be discharged into the atmosphere. On the basis that the cleaning nozzle is arranged on the top of the shell to spray downward, the moisture discharge pipeline 12 and the exhaust pipeline 10 are arranged on the shell side wall, so as to avoid that the cleaning liquid is directly sprayed into the moisture discharge pipeline 12 and the exhaust pipeline 10 when the cleaning liquid is sprayed, and to avoid that the cleaning liquid with impurities pollutes the drum 8 and the gas treatment device.

[0035] Further, in the embodiment, the shell bottom is provided with a sewage discharge pipe 5 which can communicate with the outside. The cleaning liquid with impurities will flow to the shell bottom under the action of gravity, and then be quickly discharged from the shell through the sewage discharge pipe 5. The sewage discharge pipe 5 can be connected to a ditch, a waste liquid collector or other liquid collection place, so as to prevent the liquid with impurities from causing pollution.

[0036] Further, in the embodiment, the sewage discharge pipe 5 is provided with a communication valve which can control the opening and closing of the sewage discharge pipe 5. The sewage discharge pipe 5 is connected to a ditch. When the impeller in the fan 9 rotates, negative pressure is generated. If the sewage discharge pipe 5 arranged on the shell bottom is always kept in communication, dirty gas in the ditch is easy to be sent into the fan 9 shell, causing pollution. Therefore, the communication valve blocks the sewage discharge pipe 5 when the fan 9 works to prevent dirty gas from entering, and makes the sewage discharge pipe 5 communicate with the ditch to discharge waste liquid when the fan 9 is cleaned.

[0037] Further, in the embodiment, the communication valve is a manual ball valve 4. The operator can manually rotate the operation handle of the manual ball valve 4, so as to change the opening and closing state of the sewage discharge pipe 5. In some other embodiments, the communication valve can also be an electric control valve which is controlled by the above-mentioned controller. When the drum 8 and the fan 9 start cleaning, the controller controls the electromagnetic valve 7 and the electric control valve to make the second liquid pipeline 3 and the sewage discharge pipe 5 communicate, so that the cleaning liquid can flow into the sewage discharge pipe 5 after cleaning the fan 9.

[0038] Specifically, in the embodiment, the first liquid pipeline, the second liquid pipeline 3 and the sewage discharge pipe 5 are all stainless steel pipelines. The stainless steel pipeline has good structural strength and corrosion resistance, and can avoid dirty corrosion of the pipeline. In some other embodiments, the first liquid pipeline, the second liquid pipeline 3 and the sewage discharge pipe 5 can also be corrosion-resistant pipelines such as PVC pipelines and aluminum plastic pipelines, and the embodiment does not limit this.

[0039] Specifically, in the embodiment, two ends of the first liquid pipe are connected to the liquid supply device and the drum 8 respectively, and two ends of the second liquid pipe 3 are connected to the first liquid pipe and the fan 9 respectively. That is, the second liquid pipe 3 is not directly connected to the liquid supply device, but is connected to the first liquid pipe. At this time, the end of the second liquid pipe 3 only needs to be connected to the first liquid pipe close to the fan 9, the length is reduced, the overall length of the pipeline is reduced, and the production cost is reduced. In some other embodiments, the two ends of the second liquid pipe 3 can also be connected to the liquid supply device and the fan 9 respectively, and the two ends of the first liquid pipe are connected to the second liquid pipe 3 and the drum 8 respectively.

[0040] Further, in the embodiment, the complete working process of the fan impeller cleaning system is as follows: when the drum 8 and the fan 9 enter the equipment cleaning stage after production, the liquid supply device supplies water, and the controller controls the electric valve assembly to make the second liquid pipe 3 communicate, the water in the second liquid pipe 3 washes the impeller through the cleaning nozzle 1, and the sewage after cleaning is discharged into the trench through the sewage pipe 5.

[0041] Obviously, the above-mentioned embodiments of the present application are only examples for clearly illustrating the present application, and are not a limitation on the embodiments of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent substitution and improvement made within the spirit and principle of the present application shall be included in the protection scope of the claims of the present application.
