Description

Technical Field

[0001] This utility model relates to the field of cement processing technology, specifically to a device for cleaning cement bags. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder that forms a paste when mixed with water. It can harden in air or water and firmly bind materials such as sand and stone together. Early mixtures of lime and volcanic ash are very similar to modern lime-volcanic ash cement. Concrete made by binding crushed stone with cement not only has high strength after hardening but also resists erosion from fresh or salt water. For a long time, it has been widely used as an important binder in civil engineering, water conservancy, national defense and other projects.

[0003] A cement bag cleaning device for cement production and processing, as disclosed in Chinese Patent Publication No. CN222519279U, includes: a box body, electric conveyors symmetrically fixedly installed at both ends of the box body, a flipping component located in the middle of the box body, and industrial vacuum cleaners symmetrically fixedly installed on the top of the box body, with a dust suction hood fixedly installed at the air inlet end of the industrial vacuum cleaner, the lower end of the dust suction hood extending into the interior of the box body. This utility model, with its flipping component, cleaning rollers, and industrial vacuum cleaner, cleans one side of the cement bag on one electric conveyor using the cleaning roller at one end of the box body and the dust suction hood at the lower end of the industrial vacuum cleaner. Then, the flipping component flips the cement bag and transports it to the surface of another electric conveyor. The other side of the cement bag is then cleaned by the cleaning roller at the other end of the box body and the dust suction hood at the lower end of the industrial vacuum cleaner, achieving cleaning of both sides of the cement bag and improving the cleaning effect.

[0004] In the process of developing this application, the inventors discovered at least the following problems with the technology: Although the above technical solution can clean both sides of the cement bag and improve the cleaning efficiency, when cleaning the cement bag, the dust on the surface of the cement bag will be swept onto the conveyor belt. Therefore, when the cement bag is transported, the dust on the conveyor belt will stick to the cement bag again and will be carried out. Therefore, further improvements can be made. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides the following technical solution: a cement bag cleaning device, comprising a housing, a flipping assembly located in the middle of the housing, belt conveyors located on both sides of the flipping assembly inside the housing, industrial vacuum cleaners fixedly installed at both ends of the top of the housing, and automatically lifting doors located at both ends of the housing. Photoelectric sensors are also installed at both ends of the housing to detect cement bags and control the lifting doors to open and close. A cleaning assembly is located inside the housing and at the bottom of the belt conveyors. This cleaning assembly is used to clean cement dust adhering to the surface of the belt conveyors. The belt conveyors transport the cement bags into the housing for cleaning. The closing of the lifting doors on both sides creates a sealed environment inside the housing, preventing dust from escaping. The industrial vacuum cleaners collect and absorb the dust generated during cleaning, while the cleaning assembly cleans the dust adhering to the surface of the belt conveyors, preventing dust from re-adhering to the cement bags during flipping.

[0006] As an optimization, the dust removal assembly includes slide rails fixedly installed on the inner wall of the housing, and the slide rails are symmetrically arranged on both sides below the belt conveyor. A reciprocating cleaning plate is slidably connected between the two slide rails. Brushes are provided on the top sides of both sides of the reciprocating cleaning plate. A nozzle is provided in the middle of the top side of the reciprocating cleaning plate. An air inlet pipe for air supply is connected to the bottom side of the reciprocating cleaning plate. It also includes a reciprocating transmission component that drives the reciprocating cleaning plate to move back and forth. The reciprocating transmission component drives the reciprocating cleaning plate to move back and forth, which in turn drives the brushes to clean and remove the dust on the surface of the belt conveyor.

[0007] As an optimization, dust extraction hoods for dust extraction are provided on both the upper and lower sides of the slide rail. The dust extraction hoods are connected to the vacuum pump via hoses to prevent the dust after cleaning from being re-spread onto the cement bag.

[0008] As an optimization, sliders are fixedly installed at both ends of the reciprocating cleaning plate, and the sliders are slidably connected inside the slide rail, so as to limit and support the reciprocating cleaning plate through the sliders on both sides.

[0009] As an optimization, several balls are embedded on both the upper and lower sides of the slider, and slide tracks are opened on the inner walls of both the upper and lower sides of the slide rail. The balls are rolled and connected inside the slide tracks, and the friction is reduced by the balls rolling along the slide tracks.

[0010] As an optimization, the reciprocating transmission component includes a servo motor. A crank is fixedly mounted on the top of the output shaft of the servo motor. A push-pull plate is rotatably connected to the end of the crank. A connecting shaft is rotatably connected between the other end of the push-pull plate and the bottom center of the reciprocating cleaning plate. By starting the servo motor to drive the crank to rotate, the push-pull plate can be used to push and pull the reciprocating cleaning plate, thereby causing the reciprocating cleaning plate to move back and forth for dust removal.

[0011] As an optimization, the nozzle is provided with a fixing ring and a blocking plate inside. The fixing ring is fixedly installed inside the nozzle, and the outer side of the blocking plate has a sealing sleeve that slides tightly against the inner wall of the nozzle. A spring is fixedly installed between the fixing ring and the blocking plate. The spring's own elasticity will cause the blocking plate to block inside the nozzle, thereby preventing external dust from entering.

[0012] The beneficial effects of this utility model are: This cement bag cleaning device uses a servo motor to drive a crank, which in turn drives a push-pull plate to move a reciprocating cleaning plate. This causes the brush on the top side of the reciprocating cleaning plate to clean and remove dust from the surface of the belt conveyor. At the same time, air is sprayed out from the nozzle along the air inlet pipe, which further improves the cleaning effect. The cleaned dust is then extracted from the dust extraction hood, thus preventing the cleaned dust from being re-spread onto the cement bags. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1 A cement bag cleaning device includes a housing 1. A flipping component is located in the middle of the housing 1. Belt conveyors 2 are installed on both sides of the flipping component inside the housing 1. Industrial vacuum cleaners 3 are fixedly installed at both ends of the top of the housing 1. Automatic lifting doors 4 are installed at both ends of the housing 1. Photoelectric sensors are installed at both ends of the housing 1 to detect cement bags and control the lifting doors 4 to open and close. A cleaning component is installed inside the housing 1 and at the bottom of the belt conveyors 2. The cleaning component is used to clean the cement dust adhering to the surface of the belt conveyors 2. The cement bags are transported into the housing 1 by the belt conveyors 2 for cleaning. The lifting doors 4 on both sides are closed to form a sealed environment inside the housing 1 to prevent dust from escaping. The industrial vacuum cleaners 3 absorb and collect the dust generated during the cleaning process. At the same time, the cleaning component cleans the dust adhering to the surface of the belt conveyors 2 to prevent dust from sticking to the cement bags again when flipping the bags. Please see Figure 2-3 The dust removal assembly includes a slide rail 5 fixedly installed on the inner wall of the housing 1, and the slide rail 5 is symmetrically arranged on both sides of the belt conveyor 2. A reciprocating cleaning plate 6 is slidably connected between the two slide rails 5. A slider 10 is fixedly installed at both ends of the reciprocating cleaning plate 6, and the slider 10 is slidably connected inside the slide rail 5. The slider 10 on both sides limits and supports the reciprocating cleaning plate 6, so that the reciprocating cleaning plate 6 keeps sliding horizontally. Several balls 11 are embedded on the upper and lower sides of the slider 10. The upper and lower inner walls of the slide rail 5 are provided with slide rails 12, and the balls 11 are slidably connected inside the slide rails 12. When the slider 10 slides inside the slide rail 5, it will drive the balls 11 to roll along the slide rails 12, thereby reducing friction. Please see Figure 2-3The reciprocating cleaning plate 6 is equipped with brushes 7 on both sides of the top. A nozzle 8 is provided in the middle of the top side of the reciprocating cleaning plate 6. An air inlet pipe 9 for air supply is connected to the bottom side of the reciprocating cleaning plate 6. It also includes a reciprocating transmission component that drives the reciprocating cleaning plate 6 to move back and forth. The reciprocating transmission component drives the reciprocating cleaning plate 6 to move back and forth, which in turn drives the brushes 7 to clean and brush away the dust on the surface of the belt conveyor 2. At the same time, air is supplied along the air inlet pipe 9 and sprayed out from the nozzle 8, which can further improve the dust removal effect. Please see Figure 2-3 Dust collection hoods for dust extraction are provided on both the upper and lower sides of the slide rail 5. The dust collection hoods are connected to the air extraction machine via hoses. By starting the air extraction machine, the cleaned dust can be extracted from the dust collection hoods, preventing the cleaned dust from being scattered back onto the cement bag. Please see Figure 2-3 The reciprocating transmission component includes a servo motor 13. A crank 14 is fixedly mounted on the top of the output shaft of the servo motor 13. A push-pull plate 15 is rotatably connected to the end of the crank 14. A connecting shaft 16 is rotatably connected between the other end of the push-pull plate 15 and the bottom center of the reciprocating cleaning plate 6. By starting the servo motor 13 to drive the crank 14 to rotate, the push-pull plate 15 can push and pull the reciprocating cleaning plate 6, thereby causing the reciprocating cleaning plate 6 to move back and forth for dust removal. Please see Figure 4 The nozzle 8 is equipped with a fixing ring 17 and a blocking plate 18 inside. The fixing ring 17 is fixedly installed inside the nozzle 8. The outer side of the blocking plate 18 has a sealing sleeve 19 that slides tightly against the inner wall of the nozzle 8. A spring 20 is fixedly installed between the fixing ring 17 and the blocking plate 18. The spring 20 will block the blocking plate 18 inside the nozzle 8 by its own elasticity, thereby preventing external dust from entering. When ventilation is applied, the blocking plate 18 will be pushed outward, so as not to hinder the normal dust blowing and cleaning operation.

[0018] In use, the cement bags are first transported to each other by the belt conveyor 2. When they pass the lifting door 4, the photoelectric sensor controls the lifting door 4 to rise, so that the cement bags can be transported into the box 1 for cleaning. At the same time, the lifting door 4 will fall down to seal the inside of the box 1. Then, the industrial vacuum cleaner 3 will suck up the dust floating inside. Finally, the cement bags can be transported out from the belt conveyor 2 on the other side. The servo motor 13 is activated, which drives the crank 14 to rotate. This, in turn, drives the reciprocating cleaning plate 6 to move back and forth via the push-pull plate 15. The brush 7 on the top side of the reciprocating cleaning plate 6 can clean and remove the dust from the surface of the belt conveyor 2. At the same time, air is delivered through the air inlet pipe 9 and sprayed out from the nozzle 8, which can further improve the dust removal effect. The cleaned dust is then extracted from the dust extraction hood to prevent the cleaned dust from being re-spread onto the cement bag.

[0019] In summary, this cement bag cleaning device, by starting the servo motor 13 to drive the crank 14 to rotate, can push and pull the reciprocating cleaning plate 6 through the push-pull plate 15. This will drive the brush 7 on the top side of the reciprocating cleaning plate 6 to clean and brush away the dust on the surface of the belt conveyor 2. At the same time, air is delivered along the air inlet pipe 9 and sprayed out from the nozzle 8, which can further improve the cleaning effect. Moreover, the cleaned dust will be extracted from the dust extraction hood, thereby preventing the cleaned dust from being re-spread onto the cement bag.
