Technical Field

[0001] The utility model relates to the technical field of ventilation, in particular to a ventilation fan cleaning device for a cement production workshop. Background Technique

[0002] When workers are working in a cement production workshop, in order to avoid the temperature in the workshop being too high, a ventilation fan is usually used to ventilate the workshop. However, after the ventilation fan is used for a period of time, a lot of cement and dust may adhere to the inner wall of the ventilation duct. In order to avoid the ventilation effect of the ventilation fan being affected, it is necessary to clean the cement and dust on the inner wall of the ventilation duct.

[0003] At present, when cleaning the inside of the ventilation fan, usually after the ventilation fan stops running, workers climb into the ventilation duct and then manually wipe the cement and dust on the inner wall of the ventilation duct with a rag. However, the traditional cleaning method requires a large amount of manpower, and because there are many components inside the ventilation duct, during the cleaning process, people's actions will be affected by the components, making it inconvenient for people to carry out the cleaning work.

[0004] In view of the above-mentioned shortcomings, we specifically set up a ventilation fan cleaning device for a cement production workshop that can automatically clean the inner wall of the ventilation duct. Content of the Utility Model

[0020] The utility model will be further described below with reference to the embodiments shown in the drawings.

[0021] Embodiment 1: A ventilation fan cleaning device for a cement production workshop, as Figure 1 , Figure 2 , Figure 3 andFigure 4 As shown in the figure, it includes a ventilation duct 1, a motor 3, a support rod 4, a fan blade 5 and a cleaning component. The support rods 4 are fixedly connected along the circumferential direction on the rear side of the ventilation duct 1. The motor 3 is installed between the rear sides of the support rods 4. The fan blade 5 is connected to the front side of the output shaft of the motor 3. A cleaning component is provided on the output shaft of the motor 3, and the cleaning component can clean the inner wall of the ventilation duct 1.

[0022] As Figure 3 and Figure 5 shown in the figure, the cleaning component includes a brush 10, a connecting rod 11 and a turntable 12. A plurality of connecting rods 11 are fixedly connected along the circumferential direction on both the front and rear parts of the output shaft of the motor 3. The number of turntables 12 is two, and the two turntables 12 are respectively connected between the front connecting rods 11 and between the rear connecting rods 11. The number of brushes 10 is two, and the two brushes 10 are respectively connected between the left parts and the right parts of the two turntables 12. The brush 10 is in contact with the inner wall of the ventilation duct 1, and the brush 10 is a wire brush, so that the cleaning effect of the brush 10 can be improved.

[0023] When the ventilation fan cleaning device in this cement production workshop is in use, first install the ventilation duct 1 on the wall of the workshop through the mounting ring 2, and then turn on the motor 3, so that the output shaft of the motor 3 drives the fan blade 5 to rotate, so as to ventilate the interior of the workshop. After the ventilation duct 1 is used for a period of time, a lot of dust and cement may adhere to the inner wall of the ventilation duct 1. In order to avoid affecting the ventilation effect, it is necessary to clean the dust and cement on the inner wall of the ventilation duct 1. When the output shaft of the motor 3 rotates, the motor 3 will also drive the brush 10 and the turntable 12 to rotate through the connecting rod 11. At this time, the brush 10 will clean the dust and cement adhering to the inner wall of the ventilation duct 1, so that the dust and cement on the inner wall of the ventilation duct 1 can be automatically cleaned, preventing the ventilation effect from being affected. When people do not need ventilation, just turn off the motor 3. In summary, the workshop can be ventilated, and during the ventilation process, the dust and cement on the inner wall of the ventilation duct 1 can be automatically cleaned without manual cleaning by people.

[0024] Embodiment 2: On the basis of Embodiment 1, as Figure 1 , Figure 2 and Figure 3 shown in the figure, it further includes a filter screen 6 and a knocking component. The filter screen 6 is connected to the front side of the ventilation duct 1, and the filter screen 6 can block foreign impurities from the outside. The knocking component is arranged on the front turntable 12.

[0025] As Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the knocking component includes a pressing plate 7, a ram 8, a fixing rod 9, a spring 13 and a slider 14. The fixing rod 9 is connected to the left front side of the front turntable 12. The slider 14 is slidably connected inside the fixing rod 9. The spring 13 is connected between the rear side of the slider 14 and the inner wall of the fixing rod 9. The ram 8 is connected to the front side of the slider 14. The pressing plate 7 is connected to the front side of the upper inner wall of the ventilation duct 1. The pressing plate 7 is arranged from narrow to wide from left to right. The pressing plate 7 is in pressing cooperation with the ram 8.

[0026] As Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, it further includes two mounting rings 2 which are respectively connected to the front and rear parts of the lower side of the ventilation duct 1. The mounting rings 2 can facilitate people to install the ventilation duct 1.

[0027] When people are ventilating, the filter screen 6 will block foreign impurities from the outside to prevent foreign impurities from entering the inside of the ventilation duct 1. At the same time, when the turntable 12 rotates, the front turntable 12 will also drive the ram 8, the fixing rod 9 and the slider 14 to rotate. When the ram 8 rotates to contact the rear side of the pressing plate 7, the pressing plate 7 will press the ram 8 backward. Then the ram 8 drives the slider 14 to move backward, and the spring 13 is compressed. Subsequently, when the ram 8 rotates away from the rear side of the pressing plate 7, under the action of the spring 13, the slider 14 drives the ram 8 to move forward. At this time, the ram 8 will knock on the filter screen 6, so as to prevent the filter screen 6 from being blocked by impurities. Subsequently, when people do not need ventilation and turn off the motor 3 and the turntable 12 stops rotating, the ram 8, the fixing rod 9 and the slider 14 will also stop rotating. In summary, foreign impurities can be prevented from entering the inside of the ventilation duct 1 during the ventilation process.
