Description

Technical Field

[0001] This utility model relates to the field of ventilation structure technology, and more specifically, to a factory ventilation structure. Background Technology

[0002] A factory building typically refers to a building used for production or supporting facilities for production. When constructing a factory building, ventilation structures, such as ventilation ducts and exhaust fans, are usually installed on the inner walls of the factory building to improve the subsequent ventilation effect. These ventilation structures improve the efficiency of air circulation within the factory building and enhance the ventilation effect.

[0003] Publication number CN220958769U discloses a ventilation structure for a steel structure workshop. The technical solution includes a ventilation duct, a filter frame inside the ventilation duct, a cooling fan on one side of the filter frame, a clamping plate on both sides of the filter frame, a sealing groove at the top of the ventilation duct, and a sealing block that matches the sealing groove fixedly connected to the top of the filter frame.

[0004] When the above-mentioned technical solution uses a ventilation structure to ventilate the factory, the cooling fan can draw outside air into the ventilation duct, improving the efficiency of air circulation in the factory. At the same time, the filter frame can screen out impurities in the ventilation duct and can also be removed from the ventilation duct for easy cleaning.

[0005] However, the above technical solution does not include a structure for collecting impurities inside the ventilation duct. As a result, when the ventilation duct is used to ventilate the factory, the impurities screened out by the filter frame will accumulate inside the ventilation duct, causing blockage and affecting the ventilation effect.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a factory ventilation structure that solves the problem that when using ventilation ducts to exchange air in a factory, the impurities screened by the filter frame will accumulate in the ventilation duct, causing blockage and affecting the ventilation effect.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a factory ventilation structure, including a ventilation duct and a filter screen located inside the ventilation duct, a support frame fixedly connected inside the ventilation duct, a motor fixedly connected to the support frame, a rotating rod fixedly connected to the output end of the motor, a plurality of fan blades fixedly connected to the rotating rod, a collection frame detachably connected to the bottom of the ventilation duct and communicating with itself, the collection frame being located directly below the filter screen, and a cleaning component for cleaning the surface of the filter screen being provided inside the ventilation duct.

[0009] By adopting the above technical solution, when using ventilation ducts to ventilate the factory, the motor is started, and the output end of the motor drives the rotating rod to rotate. At the same time, the rotating rod drives several fan blades to rotate. The fan blades can draw outside air into the ventilation duct, and filter the impurities in the air through the filter screen, thereby achieving the effect of filtration of the factory. While the filter screen is screening the impurities in the air, the cleaning component can clean the impurities on the filter screen. The cleaned impurities will fall into the collection frame and be collected by the collection frame, thereby achieving the effect of cleaning and collecting impurities on the filter screen, avoiding the accumulation of impurities in the ventilation duct, and avoiding affecting the ventilation effect of the ventilation duct.

[0010] The present invention is further configured such that: the cleaning assembly includes a plurality of cleaning frames one and cleaning frames two respectively rotatably connected to both sides of the filter screen; the rotating rod passes through the filter screen and is rotatably connected to the filter screen; and the cleaning frames one and cleaning frames two are fixedly connected to the rotating rod.

[0011] By adopting the above technical solution, when cleaning both sides of the filter screen, the rotating rod drives the first and second cleaning frames to rotate. With the setting of the first and second cleaning frames, the impurities adhering to the surface of the filter screen can be scraped off, thereby achieving the effect of cleaning both sides of the filter screen.

[0012] The present invention is further configured such that: a connecting rod is rotatably connected inside the cleaning frame, and a plurality of bristles are fixedly connected to the side wall of the connecting rod, and the bristles and the filter screen are in contact with each other.

[0013] By adopting the above technical solution, when cleaning one side of the filter screen in the cleaning frame, the rotating rod drives the cleaning frame to rotate, and the cleaning frame drives the connecting rod and brush bristles to rotate. The brush bristles can clean one side of the filter screen, thereby achieving the effect of cleaning the filter screen. The brush bristles can further improve the cleaning effect of the filter screen in the cleaning frame. At the same time, the rotating rod can drive the brush bristles to rotate and apply centrifugal force to the brush bristles, throwing the impurities adhering to the brush bristles towards the inner wall of the cleaning frame, thereby achieving the effect of cleaning the brush bristles and improving the cleaning effect of the brush bristles on the filter screen.

[0014] The present invention is further configured such that: a through groove is provided on one side of the cleaning frame 2 for impurities to enter, and an opening is provided at the end of the cleaning frame 2 away from the rotating rod.

[0015] By adopting the above technical solution, when the rotating rod drives the second cleaning frame to rotate, the impurities scraped by the second cleaning frame can enter the interior of the second cleaning frame through the through groove. The second cleaning frame then moves the impurities towards the collection frame, while centrifugal force is applied to the impurities. When the impurities are located at the second cleaning frame, they are separated from the second cleaning frame by the centrifugal force and fall into the collection frame. This achieves the effect of the second cleaning frame cleaning the filter screen. By using the above method, the problem of impurities being blown into the ventilation duct by the wind after the second cleaning frame scrapes the impurities off the filter screen can be avoided, thus improving the collection effect of the second cleaning frame on the impurities on the filter screen.

[0016] The present invention is further configured such that: an installation ring is fixedly connected to the bottom of the ventilation duct, a limiting block is fixedly connected to the collection frame, and a limiting groove is provided at the bottom of the installation ring for the limiting block to slide.

[0017] By adopting the above technical solution, it is easy to install and disassemble the collection box and ventilation duct, and it is easy to clean the impurities in the collection box.

[0018] The present invention is further configured such that: a wind baffle is fixedly connected to the ventilation duct near the cleaning frame, and the wind baffle has an arc-shaped longitudinal section.

[0019] By adopting the above technical solution, when the wind blows into the collection frame, the wind will drive the dust to move along the side wall of the collection frame and make the dust come into contact with the wind deflector. At this time, the wind deflector is set with an arc-shaped longitudinal section, which can drive the wind and dust to move along the side wall of the wind deflector and return to the collection frame. This prevents the impurities in the collection frame from being affected by the wind and blown back into the ventilation duct.

[0020] The present invention is further configured such that: a support plate is fixedly connected inside the collection frame, and the support plate and the bottom of the filter screen are in contact with each other.

[0021] By adopting the above technical solution, the support effect of the collection frame on the filter screen can be improved, and the stability of the filter screen can be enhanced.

[0022] In summary, this utility model has the following beneficial effects: when the filter screen screens impurities in the air, the cleaning component can clean the impurities on the filter screen. The cleaned impurities will fall into the collection frame and be collected by the collection frame, thereby achieving the effect of cleaning and collecting impurities on the filter screen, avoiding the accumulation of impurities in the ventilation duct, and avoiding affecting the ventilation effect of the ventilation duct.

[0031] A factory ventilation structure, such as Figures 1-4As shown, the system includes a ventilation duct 1 and a filter screen 2 located inside the ventilation duct 1. A support frame 3 is fixedly connected inside the ventilation duct 1, and a motor 4 is fixedly connected to the support frame 3. A rotating rod 5 is fixedly connected to the output end of the motor 4, and several fan blades 6 are fixedly connected to the rotating rod 5. A collection frame 7, which is in communication with itself, is detachably connected to the bottom of the ventilation duct 1. The collection frame 7 is located directly below the filter screen 2. A cleaning component for cleaning the surface of the filter screen 2 is provided inside the ventilation duct 1. When using the ventilation duct 1 to ventilate the factory, the motor 4 is started, and the rotating rod 5 is rotated through the output end of the motor 4. Simultaneously, the rotating rod 5 drives several fan blades 6 to rotate, which draws outside air into the ventilation duct 1 and filters impurities in the air through the filter screen 2, thereby achieving the effect of filtering the factory building. While the filter screen 2 is screening impurities in the air, the cleaning component can clean the impurities on the filter screen 2. The cleaned impurities will fall into the collection frame 7 and be collected by the collection frame 7, thereby achieving the effect of cleaning and collecting impurities on the filter screen 2, preventing impurities from accumulating in the ventilation duct 1 and avoiding affecting the ventilation effect of the ventilation duct 1.

[0032] like Figures 2-4As shown, the cleaning assembly includes several cleaning frames 8 and 9 rotatably connected to both sides of the filter screen 2. A rotating rod 5 passes through the filter screen 2 and is rotatably connected to it. Both cleaning frames 8 and 9 are fixedly connected to the rotating rod 5. When cleaning both sides of the filter screen 2, the rotating rod 5 drives the cleaning frames 8 and 9 to rotate. The arrangement of the cleaning frames 8 and 9 scrapes away impurities adhering to the surface of the filter screen 2, thus achieving the effect of cleaning both sides of the filter screen 2. A connecting rod 10 is rotatably connected inside the cleaning frame 8. Several bristles 11 are fixedly connected to the side wall of the connecting rod 10. The bristles 11 are in contact with the filter screen 2. When the cleaning frame 8 cleans one side of the filter screen 2, the rotating rod 5 drives the cleaning frame 8 to rotate, and simultaneously, the cleaning frame 8 drives the connecting rod 10 and the bristles 11 to move. The bristles 11 clean one side of the filter screen 2, thus achieving the effect of cleaning both sides of the filter screen 2. The cleaning effect is further improved by the bristles 11, which enhances the cleaning effect of the first cleaning frame 8 on the filter screen 2. The second cleaning frame 9 has a channel 12 on one side for impurities to enter, and an opening 13 at the end of the second cleaning frame 9 away from the rotating rod 5. When the rotating rod 5 drives the second cleaning frame 9 to rotate, the impurities scraped by the second cleaning frame 9 can enter the interior of the second cleaning frame 9 through the channel 12. The second cleaning frame 9 then moves the impurities towards the collection frame 7, while applying centrifugal force to the impurities. When the impurities are located at the second cleaning frame 9, they are separated from the second cleaning frame 9 by the centrifugal force through the opening 13 and fall into the collection frame 7. This achieves the cleaning effect of the second cleaning frame 9 on the filter screen 2. By using the above method, the problem of impurities being blown into the ventilation duct 1 by the wind after the second cleaning frame 9 scrapes off the impurities on the filter screen 2 can be avoided, thus improving the collection effect of the second cleaning frame 9 on the impurities on the filter screen 2.

[0033] like Figure 2 , Figure 3 As shown, an installation ring 14 is fixedly connected to the bottom of the ventilation duct 1, and a limiting block 15 is fixedly connected to the collection frame 7. The bottom of the installation ring 14 is provided with a limiting groove 16 for the limiting block 15 to slide, which facilitates the installation and disassembly of the collection frame 7 and the ventilation duct 1, and facilitates the cleaning of impurities in the collection frame 7.

[0034] like Figure 2 , Figure 3 As shown, a baffle plate 17 is fixedly connected to the ventilation duct 1 near the cleaning frame 2 9. The longitudinal section of the baffle plate 17 is arc-shaped. When the wind blows into the collection frame 7, the wind will drive the dust to move along the side wall of the collection frame 7 and make the wind and dust come into contact with the baffle plate 17. At this time, the arc-shaped longitudinal section of the baffle plate 17 can drive the wind and dust to move along the side wall of the baffle plate 17 and return to the collection frame 7. This prevents the impurities in the collection frame 7 from being affected by the wind and blown back into the ventilation duct 1.

[0035] like Figure 2 As shown, a support plate 18 is fixedly connected inside the collection frame 7. The support plate 18 and the bottom of the filter screen 2 are in contact with each other, which can improve the support effect of the collection frame 7 on the filter screen 2 and improve the stability of the filter screen 2.

[0036] The working principle of this utility model is as follows: When using ventilation duct 1 to ventilate the factory, the motor 4 is started, and the output end of the motor 4 drives the rotating rod 5 to rotate. At the same time, the rotating rod 5 drives several fan blades 6 to rotate. The fan blades 6 can draw outside air into the ventilation duct 1 and filter impurities in the air through the filter screen 2, thereby achieving the effect of filtration of the factory. While the filter screen 2 is sieving impurities in the air, the rotating rod 5 drives the cleaning frame 1 8 and the cleaning frame 2 9 to rotate. The cleaning frame 1 8 and the cleaning frame 2 9 can scrape off the impurities adhering to the surface of the filter screen 2. The cleaned impurities will fall into the collection frame 7 and be collected by the collection frame 7, thereby achieving the effect of cleaning and collecting impurities on the filter screen 2, avoiding the accumulation of impurities in the ventilation duct 1 and avoiding affecting the ventilation effect of the ventilation duct 1.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
