[0002] In industrial production, many processes need to be carried out in a clean environment, such as food processing, pharmaceutical production and integrated circuit manufacturing. In order to meet these needs, clean rooms came into being, and the dust removal device in the clean room is performed by the FFU fan filter unit. As the core component of the clean room, the FFU fan filter unit removes dust and particles in the air to provide a clean production environment.

[0003] Existing dust removal devices are mostly composed of a motor, fan blades, filter plates and filters. The motor drives the fan blades to rotate and inhale indoor air. The filter plate performs a preliminary filter on the dust, and then the dust is filtered for a second time through its filter. After filtration, the clean air is evenly delivered at the outlet with a wind force of 0.45m / s.

[0004] When the existing dust removal device is not in use, the filter plate is exposed to the outside. Over time, dust is easily attached to the surface, which increases the workload during subsequent use and causes the dust removal effect to deteriorate. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1 - Figure 4 As shown, a dust removal device for a clean room for industrial production includes a shell 1, a filter table 2 is fixedly connected to the top of the shell 1, a first rotating shaft 3 is arranged inside the filter table 2, a motor is fixedly connected to the bottom end of the first rotating shaft 3, the motor is used to drive the first rotating shaft 3 to rotate, a fan blade 4 is fixedly connected to the outer side of the first rotating shaft 3, a filter plate 5 is fixedly connected to the top of the filter table 2, a baffle 6 is arranged at the top of the filter table 2, a blocking mechanism is arranged on the outer side of the baffle 6, the blocking mechanism is used to block the filter plate 5, the blocking mechanism includes a spur gear 7, a transmission mechanism is arranged on the outer side of the first rotating shaft 3, the transmission mechanism is used to drive the blocking mechanism to operate, the transmission mechanism includes a first sprocket 24, and the first sprocket 24 is fixedly connected to the outer side of the first rotating shaft 3.

[0022] In the initial state, the baffle 6 is located directly above the filter station 2, covering the filter station 2, so that external dust cannot adhere to the surface of the filter plate 5. When the fan blades 4 are running, the motor will first drive the first shaft 3 to rotate, and the first shaft 3 will then drive the fan blades 4 to rotate. During the rotation of the first shaft 3, the first sprocket 24 will be driven to rotate synchronously, and the first sprocket 24 will drive the spur gear 7 to rotate through the transmission mechanism. The spur gear 7 will eventually drive the baffle 6 to move through the blocking mechanism, thereby breaking away from the coverage of the filter station 2 and exposing the filter plate 5. In this way, the normal dust suction work of the dust removal device will not be hindered when the dust removal device is in normal operation.

[0023] like Figure 1 - Figure 4 As shown, the blocking mechanism also includes a rack 8, which is fixedly connected to one side of the baffle 6 close to the spur gear 7, and the rack 8 is meshed with the spur gear 7. A pair of fixed plates 9 are fixedly connected to the top of the shell 1, and a limiting rod 10 is fixedly connected between the pair of fixed plates 9. A connecting plate 11 is slidably connected to the outer side of the limiting rod 10, and the connecting plate 11 is fixedly connected to the outer side of the baffle 6. A spring 12 is fixedly connected between the connecting plate 11 and the fixed plate 9, and the spring 12 is sleeved on the outer side of the limiting rod 10.

[0024] The transmission mechanism drives the spur gear 7 to Figure 3When the viewing angle rotates clockwise, the spur gear 7 drives the rack 8 to move toward the baffle 6. At this time, the baffle 6 gradually breaks away from the coverage of the filter station 2, and drives the connecting plate 11 to move and squeeze the spring 12, so that the spring 12 is deformed to generate elastic potential energy. As the rack 8 continues to move, the rack 8 will break away from the meshing with the spur gear 7, while the spur gear 7 is still in a rotating state. The spring 12 continuously drives the baffle 6 to reset through the connecting plate 11. In the process of the baffle 6 driving the rack 8 to reset, the top of the rack 8 is continuously hit by the spur gear 7, thereby avoiding The rack 8 is reset, thereby preventing the baffle 6 from resetting and blocking the filter plate 5 during the operation of the device. When the operation of the device is completed, the driving force provided by the transmission mechanism to the spur gear 7 is terminated, and the spring 12 is no longer subjected to force at this time, and the elastic potential energy will be released, driving the baffle 6 to reset through the connecting plate 11 to cover the filter plate 5 again. The reset of the baffle 6 will drive the rack 8 to reset, and the process of resetting the rack 8 will drive the spur gear 7 to rotate in the opposite direction. It should be noted that the elastic coefficient of the spring 12 can support the friction force generated when the spur gear 7 and the rack 8 are reset.

[0025] like Figure 3 and Figure 4 As shown, the transmission mechanism also includes a second rotating shaft 13, which is fixedly connected to the inside of the spur gear 7, and one end of the second rotating shaft 13 away from the spur gear 7 is rotatably connected to the top of the shell 1, and a second sprocket 14 is fixedly connected to the outer side of the second rotating shaft 13, and a chain 15 is wound between the second sprocket 14 and the first sprocket 24.

[0026] When the first rotating shaft 3 rotates, it drives the first sprocket 24 to rotate. The rotation of the first sprocket 24 drives the second sprocket 14 to rotate through the chain 15. The rotation of the second sprocket 14 eventually drives the spur gear 7 to rotate through the second rotating shaft 13.

[0027] like Figure 1 As shown, two groups of the pair of fixing plates 9 , limiting rods 10 , connecting plates 11 and springs 12 are provided and symmetrically distributed on both sides of the baffle 6 .

[0028] The fixing plate 9, the limiting rod 10, the connecting plate 11 and the spring 12 are provided in two groups, which can limit the two sides of the baffle 6 at the same time, avoiding the situation in which only one group is provided, and the baffle 6 will be stuck when moving, thereby improving the smoothness of the operation of the device.

[0029] like Figure 5 As shown, a plurality of scraper rods 16 are glued to the bottom end of the baffle plate 6, and one end of the scraper rod 16 away from the baffle plate 6 is in contact with the top end of the filter plate 5, and the scraper rod 16 is made of rubber.

[0030] The scraper rod 16 can be set to scrape cotton wool and the like attached to the surface of the filter plate 5 during the movement of the baffle plate 6. The scraper rod 16 is made of rubber material with a certain elasticity and can fit the surface of the filter plate 5.

[0031] Working principle: in the initial state, the baffle 6 is located directly above the filter platform 2, covering the filter platform 2, so that the external dust cannot adhere to the surface of the filter plate 5. When the fan blades 4 are running, the motor will first drive the first shaft 3 to rotate, and the first shaft 3 will then drive the fan blades 4 to rotate. During the rotation of the first shaft 3, the first sprocket 24 will be synchronously driven to rotate, and the first sprocket 24 will drive the spur gear 7 to rotate through the transmission mechanism. The spur gear 7 will eventually drive the baffle 6 to move through the blocking mechanism, thereby breaking away from the coverage of the filter platform 2 and exposing the filter plate 5. In this way, the normal dust suction work of the dust removal device will not be hindered when the dust removal device is in normal operation. The transmission mechanism drives the spur gear 7 to Figure 3 When the viewing angle rotates clockwise, the spur gear 7 will drive the rack 8 to move in the direction of the baffle 6. At this time, the baffle 6 gradually disengages from the coverage of the filter station 2, and drives the connecting plate 11 to move and squeeze the spring 12, causing the spring 12 to deform and generate elastic potential energy. As the rack 8 continues to move, the rack 8 will disengage from the meshing with the spur gear 7, while the spur gear 7 is still in a rotating state, and the spring 12 will continuously drive the baffle 6 to reset through the connecting plate 11. In the process of the baffle 6 driving the rack 8 to reset, the top of the rack 8 is continuously hit by the spur gear 7, thereby avoiding the reset of the rack 8, and then preventing the baffle 6 from resetting during the operation of the device and blocking the filter plate 5. When the operation of the device is completed, the driving force provided by the transmission mechanism to the spur gear 7 ends, and the spring 12 ends at this time, and the elastic potential energy will be released, and the baffle 6 will be driven to reset through the connecting plate 11 to cover the filter plate 5 again, and the reset of the baffle 6 will drive The rack 8 is reset, and the spur gear 7 is driven to rotate in the opposite direction during the reset process of the rack 8. It should be noted that the elastic coefficient of the spring 12 can support the friction force generated when the spur gear 7 and the rack 8 are reset. When the first rotating shaft 3 rotates, it will drive the first sprocket 24 to rotate. The rotation of the first sprocket 24 then drives the second sprocket 14 to rotate through the chain 15. The rotation of the second sprocket 14 will eventually drive the spur gear 7 to rotate through the second rotating shaft 13. The fixed plate 9, the limit rod 10, the connecting plate 11 and the spring 12 are provided with two groups, which can simultaneously limit the two sides of the baffle 6 to avoid the situation that the baffle 6 will be stuck when it moves due to only one group, thereby improving the smoothness of the operation of the device. The scraper rod 16 can be provided to scrape cotton wool and the like attached to the surface of the filter plate 5 during the movement of the baffle 6. The rubber material of the scraper rod 16 has a certain elasticity and can fit the surface of the filter plate 5.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
