Description

Technical Field

[0001] The present invention relates to the technical field of aluminum profile surface cleaning equipment, and in particular to a device and method for pre-treating surface dust of raw materials for processing aluminum profiles for doors and windows. Background Art

[0002] Aluminum profiles are formed aluminum materials, manufactured by extrusion to form aluminum tube materials with different cross-sectional shapes. It is widely used in fields such as construction, automobiles, and industrial manufacturing, and is highly regarded for its strength, durability, and corrosion resistance. After the production of aluminum profiles is completed, they will be stored idle, and when it is necessary to manufacture doors and windows, the stored aluminum profiles will be taken out for use. However, before the stored aluminum profiles are used, their surfaces will have oil stains and dust due to long-term placement. When workers manufacture doors and windows, it is inconvenient for welding and surface spraying. Therefore, it is necessary to pre-clean the surface of aluminum profiles in advance when manufacturing doors and windows with aluminum profiles, and then perform surface cleaning and spraying after the doors and windows are manufactured.

[0003] Common pre-cleaning methods before using aluminum profiles mostly place the aluminum profiles inside one end of the cleaning equipment, and the aluminum profiles are moved and conveyed inside the cleaning equipment. The cleaning equipment sequentially soaks, ultrasonically vibrates and cleans, flushes aluminum chips, rinses with clean water, and dries the aluminum profiles, etc. As a result, the overall length of the cleaning equipment is relatively long, occupying a large area, and in order to reduce the equipment occupation area to a certain extent, the cleaning equipment can only briefly perform strong drying on the aluminum profiles, causing the outer wall of the aluminum profiles to be over-dried, while there is still residual moisture inside, and the drying effect of the cleaning equipment is poor. Summary of the Invention

On both sides of the outer wall of the annular filter screen, a number of fixing plates are installed along the length direction. Two adjacent fixing plates on the same side are rotatably connected to each other. On the inner wall of the body near the discharge hole, a second electric rotating shaft is rotatably installed. On the outer wall of the second electric rotating shaft, a rotating roller is installed, and the outer wall of the rotating roller abuts against the inner wall of the filter screen.

[0008] Preferably, a number of baffle plates are installed on the outer wall of the filter screen. The two ends of the baffle plates are respectively installed on the opposite surfaces of the fixing plates on both sides of the outer wall of the filter screen. An inlet hole is provided at one end of the machine cover near the discharge hole.

[0009] Preferably, an ultrasonic transducer is installed on the side of one end of the water storage tank away from the interior of the body. A sewage discharge pipe and a water inlet pipe are installed at one end of the water storage tank away from the body. One ends of the sewage discharge pipe and the water inlet pipe are communicated with the interior of the water storage tank. On both sides of the top of the end of the water storage tank located inside the body, grooves are provided.

[0010] Preferably, flow control valves are installed on the outer walls of the sewage discharge pipe and the water inlet pipe away from the body. The water inlet pipe is located above the sewage discharge pipe. A number of installation holes are provided on one side of the machine cover away from the support hole. Glass plates are slidably installed at both ends of the inner wall of the installation holes.

[0011] Preferably, an air inlet hole is provided at one end of the body away from the discharge hole. The air inlet hole penetrates through the body and the limiting plate. An air heater is installed at one end of the body away from the discharge hole. The air outlet of the air heater is communicated with the air inlet hole.

[0012] Preferably, an installation frame is installed on the top of one end of the machine cover near the air heater. Through holes are provided on both inner walls of the installation frame. Air delivery pipes are installed on both sides of the installation frame. One end of the air delivery pipe is communicated with the through hole, and the other end of the air delivery pipe is communicated with the air inlet of the air heater.

[0013] Preferably, a first electric rotating shaft is rotatably installed on the inner wall of the installation frame. An installation sleeve is installed on the outer wall of the first electric rotating shaft. A number of fan blades are installed on the outer wall of the installation sleeve.

[0014] A method for using a device for pre-treating surface dust of raw materials for door and window aluminum profiles in the present invention includes the following steps: Step 1: The staff pre - cut the aluminum profiles used for door and window manufacturing in advance, making the aluminum profiles into several aluminum profiles of specified lengths, and placing the aluminum profiles on the outer wall of the internal filter screen of the machine body from above one end of the machine body close to the discharge hole. The baffles on the outer wall of the filter screen separate adjacent aluminum profiles; Step 2: The staff add water and cleaning liquid into the water storage tank near the discharge hole, and add water into another water storage tank. The second electric rotating shaft drives the filter screen and the aluminum profiles on it to move into the machine body through the rotating roller, so that the aluminum profiles on the filter screen pass through the interiors of the two water storage tanks in sequence; Step 3: When the aluminum profiles pass through the water storage tank containing the cleaning liquid, the ultrasonic transducer cooperates with the cleaning liquid to clean the surface of the aluminum profiles. When passing through the interior of another water storage tank, the water inside cleans the surface of the aluminum profiles. And during the movement, the filter screen cooperates with the limit groove to limit and convey the aluminum profiles, so that the aluminum profiles move to the top of the heating plate; Step 4: When the filter screen rotates, the baffles on its outer wall push the aluminum profiles on the top of the heating plate to move. At the same time, the outside air enters the air heater through the mounting frame and the air delivery pipe. The air heater heats the air and blows it towards the aluminum profiles on the top of the heating plate. The air heater and the heating plate are matched to heat - dry the aluminum profiles until the dried aluminum profiles are removed from the machine body through the discharge hole.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the heating plate is located below the water storage tank, and the heating plate and the water storage tank are installed vertically, not at the same height, which can shorten the overall length of the cleaning equipment. And the distance length for drying the aluminum profiles inside is not much different from the overall length for surface cleaning of the aluminum profiles, making the cleaning equipment occupy less area. However, the drying time of the aluminum profiles is longer. And the cleaned aluminum profiles are located between the heating plate and the water storage tank, and the bottom end of the water storage tank is close to the heating plate. The high - temperature air conveyed between the water storage tank and the heating plate can better contact the surface of the aluminum profiles, making the heating - drying effect after surface cleaning of the aluminum profiles better. Moreover, the heating plate is relatively long, and the heating plate and the high - temperature air can heat - dry the surface of the aluminum profiles for a long time, without the situation of uneven drying on the surface of the aluminum profiles.

[0016] In the present invention, when the aluminum profile is conveyed to the top of the heating plate, the heating plate can heat the bottom of the aluminum profile. The water remaining on the surface of the aluminum profile will flow to the bottom outer wall through its outer wall, resulting in more water on the bottom outer wall of the aluminum profile than on its top outer wall. The heating plate heats the bottom of the aluminum profile, which can better heat and evaporate the water at the bottom of the aluminum profile. The hot air blown into the interior of the machine body can flow in the direction of the discharge hole between the heating plate at the bottom of the machine body and the water storage tank, and heat the top surface of the aluminum profile and the inner inner wall of the aluminum profile when flowing. During use, both the hot air blown by the air heater and the heating plate can dry the surface of the aluminum profile, but the drying directions are different. The heating plate mainly heats and dries the water droplets that slide down to the bottom of the aluminum profile surface, while the hot air blown by the air heater mainly dries the water remaining on the top outer wall and the inner wall of the aluminum profile, making the drying of the aluminum profile more thorough, with better drying effect and higher efficiency.

[0017] In the present invention, the baffle on the outer wall of the filter net can push the top of the aluminum profile to move in the direction of the discharge hole on the top of the heating plate, but the bottom end of the baffle will not contact the top of the heating plate, and there is a certain distance between the baffle and the heating plate, which is convenient for the hot air to flow between the heating plate and the filter net. However, several baffles will block and slow down the flow rate of the hot air, making the hot air stay in the machine body between the heating plate and the filter net for a longer time, making the heating time of the hot air on the surface of the aluminum profile longer, and improving the heat utilization rate in the hot air.

[0018] In the present invention, several aluminum profiles are separated from each other by the baffle on the outer wall of the filter net. The baffle can prevent adjacent two aluminum profiles from colliding during use, and can play a certain protective role for the aluminum profiles. At the same time, because the moving track of the top of the filter net is wavy, when the filter net drives the aluminum profiles on it to move and undulate, it can prevent the aluminum profiles from sliding on the top of the filter net. After the surface of the aluminum profile is cleaned, the filter net can drive the aluminum profile out of the water storage tank and move it into the limit groove inside the limit plate. During use, the filter net can cooperate with the inner wall of the limit groove to clamp the aluminum profile, and at the same time, the fixing plates located on both sides of the outer wall of the filter net can protect both ends of the aluminum profile.

An annular limiting groove 21 is opened on the side surface of the limiting plate 15; the discharge hole 3 can not only be used for discharging the aluminum profiles after cleaning, but also be used for dissipating the heat emitted by the air heater 14 and the heating plate 4 during use. Moreover, the water vapor evaporated when the aluminum profiles are dried and heated can also be dissipated to the outside through the discharge hole 3.

[0025] As a technical optimization scheme of the present invention, one end of the filter screen 16 far from the discharge hole 3 is located inside the limiting groove 21. A number of fixing plates 19 are installed on both sides of the outer wall of the annular filter screen 16 along the length direction. Two adjacent fixing plates 19 on the same side are rotatably connected to each other. A second electric rotating shaft 29 is rotatably installed on the inner wall of the machine body 1 near the discharge hole 3.

[0026] As a technical optimization scheme of the present invention, a number of baffle plates 22 are installed on the outer wall of the filter screen 16. Both ends of the baffle plate 22 are installed on the opposite surfaces of the fixing plates 19 on both sides of the outer wall of the filter screen 16 respectively. A feed hole 7 is opened at one end of the machine cover 2 near the discharge hole 3; during use, the baffle plates 22 can separate a number of aluminum profiles on the filter screen 16 and prevent the aluminum profiles on it from sliding when the filter screen 16 is transported and moved.

[0027] As a technical optimization solution of the present invention, an ultrasonic transducer 8 is installed on the side of one end of the water storage tank 5 far from the inside of the machine body 1. A sewage discharge pipe 9 and a water inlet pipe 10 are installed at one end of the water storage tank 5 far from the machine body 1.

Grooves 23 are provided on both sides of the top of one end of the water storage tank 5 located inside the machine body 1; the staff can discharge the impurities and sewage inside the water storage tank 5 through the sewage discharge pipe 9, which is convenient for the staff to replace the water inside the water storage tank 5.

[0028] As a technical optimization solution of the present invention, flow control valves 24 are installed on the outer walls of the ends of the sewage discharge pipe 9 and the water inlet pipe 10 far from the machine body 1. The water inlet pipe 10 is located above the sewage discharge pipe 9. A plurality of mounting holes 11 are provided on one side of the machine cover 2 far from the support hole 28. Glass plates 12 are slidably installed at both ends of the inner wall of the mounting holes 11; the staff can open and close the sewage discharge pipe 9 and the water inlet pipe 10 through the flow control valves 24.

[0029] As a technical optimization solution of the present invention, an air inlet hole 18 is provided at one end of the machine body 1 far from the discharge hole 3. The air inlet hole 18 penetrates through the machine body 1 and the limiting plate 15. An air heater 14 is installed at one end of the machine body 1 far from the discharge hole 3. The air outlet of the air heater 14 is communicated with the air inlet hole 18; the air heater 14 can heat the outside air and blow it to the surface of the aluminum profile on the top of the heating plate 4. When the aluminum profile is cylindrical or has a more complex shape, the hot air can dry the inner wall of the hole through the top of the aluminum profile and the holes on it.

[0030] As a technical optimization solution of the present invention, a mounting frame 6 is installed on the top of one end of the machine cover 2 close to the air heater 14. Through holes 27 are provided on both inner walls of the mounting frame 6. Air delivery pipes 13 are installed on both sides of the mounting frame 6.

[0031] As a technical optimization solution of the present invention, a first electric rotating shaft 25 is rotatably installed on the inner wall of the mounting frame 6. A mounting sleeve is installed on the outer wall of the first electric rotating shaft 25. A plurality of fan blades 26 are installed on the outer wall of the mounting sleeve; when the fan blades 26 rotate, they can convey the outside air into the inside of the through hole 27. At the same time, the mounting frame 6 can play a good protective role for the fan blades 26.

[0032] A usage method of a device for pre-treating surface dust of raw materials for door and window aluminum profiles in the present invention, the usage method includes the following steps: Step 1: The staff cut the aluminum profiles for door and window manufacturing in advance to make the aluminum profiles into several aluminum profiles of specified lengths, and place the aluminum profiles on the outer wall of the internal filter screen 16 of the machine body 1 from above one end of the machine body 1 close to the discharge hole 3. The baffle 22 on the outer wall of the filter screen 16 separates adjacent aluminum profiles; Step 2: The staff add clean water and cleaning liquid to the inside of the water storage tank 5 near the discharge hole 3, and add clean water to the inside of another water storage tank 5. The second electric rotating shaft 29 drives the filter screen 16 and the aluminum profiles thereon to move into the machine body 1 through the rotating roller 30, so that the aluminum profiles on the filter screen 16 pass through the inside of the two water storage tanks 5 in sequence; Step 3: When the aluminum profile passes through the inside of the water storage tank 5 containing the cleaning liquid, the ultrasonic transducer 8 cooperates with the cleaning liquid to clean the surface of the aluminum profile. When passing through the inside of another water storage tank 5, the clean water inside cleans the surface of the aluminum profile. And when moving, the filter screen 16 cooperates with the limit groove 21 to limit and convey the aluminum profile, so that the aluminum profile moves to the top of the heating plate 4; Step 4: When the filter screen 16 rotates, the baffle 22 on its outer wall pushes the aluminum profile on the top of the heating plate 4 to move. At the same time, the outside air enters the air heater 14 through the mounting frame 6 and the air delivery pipe 13. The air heater 14 heats the air and blows it to the aluminum profile on the top of the heating plate 4. The air heater 14 and the heating plate 4 match to heat and dry the aluminum profile until the dried aluminum profile moves out of the machine body 1 through the discharge hole 3.

[0033] When the present invention is in use, the filter screen 16 for conveying aluminum profiles surrounds the outside of the two water storage tanks 5, and the bottom end of the filter screen 16 is located between the water storage tank 5 and the heating plate 4. When in use, the drying device is not installed flush with the water storage tank at the same height, which can shorten the overall length of the aluminum profile cleaning equipment, and the drying and conveying distance inside it is the same as the overall length of the water storage tank 5 of the surface cleaning device of the aluminum profile, making the cleaning equipment occupy less area, but the drying time of the aluminum profile is longer. The staff divides the aluminum profiles to be used in advance into several specified lengths. At the same time, the staff connects the external water pipe to the water inlet pipes 10 on the two water storage tanks 5, and adds a certain amount of clear water into the two water storage tanks 5 through the flow control valve 24 and the water pipe, and adds a cleaning liquid into the water storage tank 5 near the discharge hole 3. The second electric rotating shaft 29 drives the rotating roller 30 thereon to rotate, and the rotating roller 30 abuts against the inner wall of the filter screen 16 at one end close to the discharge hole 3. When in use, several convex blocks are arranged on the outer wall of the rotating roller 30, so that when the rotating roller 30 abuts against the inner wall of the filter screen 16, the convex blocks are located in the filter holes on the filter screen 16. When in use, the connection between the filter screen 16 and the rotating roller 30 can be made more stable, preventing the rotating roller 30 from slipping when driving the filter screen 16 to move, and making the movement of the filter screen 16 more stable when in use.

[0034] The second electric rotating shaft 29 and the rotating roller 30 drive the filter screen 16 to move slowly. When the filter screen 16 moves, the staff can place the aluminum profiles to be cleaned on the top of the filter screen 16 from one end of the top of the machine body 1 close to the discharge hole 3, so that the aluminum profiles are placed on the top of the filter screen 16 in sequence, and several aluminum profiles are separated from each other by the baffle 22 on the outer wall of the filter screen 16. The baffle 22 can prevent adjacent two aluminum profiles from colliding with each other when in use, and can play a certain protective role for the aluminum profiles when in use. At the same time, because the moving track of the top end of the filter screen 16 is wavy, when the filter screen 16 drives the aluminum profiles thereon to move and undulate, it can prevent the aluminum profiles from sliding on the top of the filter screen 16.

[0035] Several connecting rods 20 are installed on the inner wall of the filter screen 16, and both ends of the connecting rods 20 are movably installed inside the guide grooves 17 on the inner walls of both sides of the machine body 1. When the second electric rotating shaft 29 drives the filter screen 16 to move, the several connecting rods 20 can play a good supporting role for the filter screen 16 through the guide grooves 17, preventing the filter screen 16 from deforming due to the pressure of its own and the weight of the aluminum profiles thereon when in use. At the same time, the connecting rods 20 can play a good guiding role for the movement of the filter screen 16 through the guide grooves 17, and at the same time limit the moving track of the filter screen 16.

[0036] When the filter net 16 drives the aluminum profiles thereon to move into the water storage tank 5 containing the cleaning liquid, the ultrasonic transducer 8 can convert the acoustic energy of the power ultrasonic frequency source into mechanical vibration, and radiate the ultrasonic waves to the cleaning liquid in the water storage tank 5 through the inner wall of the water storage tank 5, so that the microbubbles in the liquid can maintain vibration under the action of the sound waves, and clean the aluminum chips, oil stains generated by cutting on the surface of the aluminum profiles on the filter net 16 and the floating dust falling on its surface during idle time, which is convenient for the staff to use for welding and surface spraying when manufacturing doors and windows with aluminum profiles subsequently.

[0037] After the cleaning liquid in the water storage tank 5 finishes cleaning the surface of the aluminum profiles, the filter net 16 drives the cleaned aluminum profiles to be conveyed into the interior of another water storage tank 5. The clean water in the water storage tank 5 can clean the surface of the aluminum profiles again and clean the residual cleaning liquid on the surface of the aluminum profiles at the same time. After the surface of the aluminum profiles is cleaned, the filter net 16 can drive the aluminum profiles to move out of the water storage tank 5 and move into the limiting groove 21 inside the limiting plate 15. During use, the filter net 16 can cooperate with the inner wall of the limiting groove 21 to clamp the aluminum profiles. At the same time, the fixing plates 19 on both sides of the outer wall of the filter net 16 can protect both ends of the aluminum profiles.

[0038] The filter net 16 drives the aluminum profiles to move to the top of the heating plate 4 at the inner bottom of the machine body 1. The first electric rotating shaft 25 inside the mounting frame 6 drives a plurality of fan blades 26 to rotate through the mounting sleeve, so that the outside air enters the inside of the through hole 27 through the inside of the mounting frame 6, and the air is conveyed to the inside of the air heater 14 through the air conveying pipe 13. The air heater 14 can heat the air and blow it between the heating plate 4 at the inner bottom of the machine body 1 and the water storage tank 5. When the aluminum profiles are conveyed to the top of the heating plate 4, the heating plate 4 can heat the bottom of the aluminum profiles. During use, the water remaining on the surface of the aluminum profiles will flow to the outer wall of the bottom end through its outer wall, resulting in more water on the outer wall of the bottom end of the aluminum profiles than on the outer wall of its top end. The heating plate 4 heats the bottom end of the aluminum profiles, which can better heat and evaporate the water at the bottom end of the aluminum profiles. The hot air blown into the machine body 1 can flow in the direction of the discharge hole 3 between the heating plate 4 at the inner bottom of the machine body 1 and the water storage tank 5, and heat the top surface of the aluminum profiles and the inner wall of the aluminum profiles when flowing. During use, both the hot air blown out by the air heater 14 and the heating plate 4 can dry the surface of the aluminum profiles, but the drying directions of the two are different. The heating plate 4 mainly heats and dries the water droplets sliding down to the bottom end on the surface of the aluminum profiles, while the hot air blown out by the air heater 14 mainly dries the water remaining on the outer wall of the top end of the aluminum profiles and its inner wall, making the drying of the aluminum profiles more thorough, with better drying effect and higher efficiency.

[0039] When drying is carried out on the top of the heating plate 4, the baffle 22 on the outer wall of the filter net 16 can push the top end of the aluminum profile to move towards the discharge hole 3 on the top of the heating plate 4. However, the bottom end of the baffle 22 will not contact the top of the heating plate 4, and a certain distance is reserved between the baffle 22 and the heating plate 4 to facilitate the flow of hot air between the heating plate 4 and the filter net 16. However, several baffles 22 will block and slow down the flow rate of the hot air, so that the hot air is stored between the heating plate 4 and the filter net 16 inside the machine body 1 for a longer time, and the heating time of the hot air on the surface of the aluminum profile is longer, which can improve the heat utilization rate of the hot air. When in use, the top of the heating plate 4 is relatively smooth, reducing the friction between the aluminum profile and the top of the heating plate 4 when the aluminum profile moves on the top of the heating plate 4, and can play a certain role in protecting the aluminum profile.

[0040] When the filter net 16 moves, the baffle 22 on it pushes the top end of the aluminum profile out of the discharge hole 3, and the staff can place a storage box below the side of the discharge hole 3, so that the aluminum profile that moves out of the discharge hole 3 directly falls into the storage box, which is convenient for the staff to take the aluminum profile whose surface has been cleaned and dried. Then, the filter net 16 located below the water storage tank 5 will move above the second electric rotating shaft 29 again, and the staff can place the remaining aluminum profiles on the top of the filter net 16 again, which is convenient for cleaning and drying the surface of the remaining aluminum profiles.

[0041] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
