Description

Technical Field

[0001] The present invention relates to the technical field of galvanized steel pipe processing, and particularly to a processing device for galvanized steel pipes used in the central air-conditioning cooling water circulation system. Background Art

[0002] The central air-conditioning cooling water circulation system is a core component for maintaining the efficient operation of the air-conditioning unit. It transfers heat through circulating water to achieve the refrigeration or heating function. Since the cooling water is in a long-term flowing state and frequently contacts the metal pipes, the system poses strict requirements on the corrosion resistance, strength, and durability of the pipe materials. Galvanized steel pipes have become the mainstream choice in this field because the zinc layer covering their surfaces can effectively isolate the direct contact between water and the steel pipe substrate, significantly delaying the processes of metal oxidation and electrochemical corrosion.

[0003] According to the search, the Chinese patent document with the publication number: CN221501203U discloses a steel pipe galvanizing processing device. By turning on the second electric cylinder, the limiting block drives the first L-shaped block to move, so that the distance between the first bearing column and the second bearing column can be adjusted. Thus, it is convenient to place the steel pipe on the outer walls of the first bearing column and the second bearing column. Then, turn on the second electric cylinder to make the first L-shaped block drive the first bearing column to move towards the direction where the second bearing column is located, and use the end faces of the first L-shaped block and the second L-shaped block that are close to each other to clamp and fix the steel pipe. After that, turn on the first electric cylinder to make the telescopic rod of the first electric cylinder drive the lifting plate to move downward, place the steel pipe into the cleaning tank filled with sufficient water, and turn on the transducer to perform ultrasonic cleaning on the steel pipe, solving the problem of insufficient cleaning treatment of the pipe surface before galvanizing the steel pipe and being unable to fully remove the grease, oxides, and other impurities on the steel pipe surface.

[0004] However, in the actual use process of the above device, the steel pipes cannot be fed step by step before galvanizing.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-5 , a processing device for galvanized steel pipes used in a central air-conditioning cooling water circulation system, including a galvanizing tank 1, a heating plate 2 fixedly connected to the inner wall of the galvanizing tank 1, a resistance heating tube 3 attached to the bottom surface of the heating plate 2, a base 4 fixedly connected to the bottom of the galvanizing tank 1, and further including,

[0028] A feeding assembly 5, which includes a plurality of bent rods 51, connecting plates 52 fixedly connected to both sides of the bent rods 51, vertical support plates 53 fixedly connected to both ends of the connecting plates 52, a horizontal plate 54 fixedly connected to one side of the vertical support plates 53, a vertical support plate 55 fixedly connected to one end of the horizontal plate 54, a transmission rod 56 rotatably connected to the side surface of the vertical support plate 55, and a connecting plate 57 fixedly connected to the side surface of the vertical support plate 55, a vertical baffle 58 fixedly connected to the outer surface of the connecting plate 57, a material distribution plate 59 fixedly connected to the outer surface of the transmission rod 56, and one end of the transmission rod 56 is connected to a driving component 510;

[0029] A discharging assembly 6, which includes two side plates 61, a shaft rod 62 rotatably connected between the two side plates 61, a sprocket 63 fixedly connected to the outer surface of the shaft rod 62, a support plate 64 rotatably connected to the outer surface of the shaft rod 62, a shaft rod 65 rotatably connected to one end of the support plate 64, a sprocket 66 fixedly connected to the outer surface of the shaft rod 65, a chain 67 meshed with the sprocket 66, an L-shaped lever 68 fixedly connected to the outer surface of the chain 67, and one end of the shaft rod 62 is connected to a reduction motor 69.

[0030] Specifically, the feeding assembly 5 further includes a fixing plate 511, one end of the fixing plate 511 is welded to one side of the vertical support plate 55, and the fixing plate 511 is connected to the side surface of the galvanizing tank 1 by bolts.

[0031] Specifically, the driving component 510 includes a motor, the output shaft of the motor is connected to a first belt pulley, the first belt pulley is connected to a second belt pulley through a synchronous belt, and the center of the end face of the second belt pulley is connected to the transmission rod 56 through a coupling.

[0032] Specifically, the number of the material distribution plates 59 is multiple, and the multiple material distribution plates 59 are uniformly distributed along the axial direction of the transmission rod 56, and arc-shaped notches are formed on the outer surface of the material distribution plates 59, the arc-shaped notches fit the outer diameter of the steel pipe, and the steel pipes to be galvanized are placed on the inclined surface of the bent rod 51.

[0033] The advantages are as follows: First, multiple steel pipes to be galvanized are placed on the inclined surface of the bent rod 51. The bent rod 51 cooperates with the vertical baffle 58 to prevent the steel pipes from rolling down, enabling multiple steel pipes to be placed at one time. Subsequently, the driving component 510 works. The driving component 510 includes a motor. The output shaft of the motor drives the first pulley to rotate. Through the synchronous belt, the second pulley rotates, and then drives the transmission rod 56 to rotate. A plurality of material dividing plates 59 are fixedly connected to the outer surface of the transmission rod 56 and are evenly distributed along the axial direction. The outer surfaces of the material dividing plates 59 are provided with arc-shaped notches that fit the outer diameter of the steel pipes. As the transmission rod 56 rotates, the material dividing plates 59 rotate accordingly. When the material dividing plate 59 rotates to contact the steel pipes on the bent rod 51, the arc-shaped notches of the material dividing plate 59 catch the steel pipes. Each rotation only drives one steel pipe to move. Due to the continuous rotation of the transmission rod 56, the steel pipes are gradually driven by the material dividing plate 59 from the bent rod 51 and finally fall into the galvanizing tank 1, realizing the function of feeding the steel pipes step by step.

[0034] Specifically, the reduction motor 69 is a variable-frequency reduction motor. The reduction motor 69 is installed on the outer surface of the side plate 61. The number of L-shaped levers 68 is multiple, and the distance between adjacent L-shaped levers 68 is equal.

[0035] Specifically, a temperature sensor is provided in the galvanizing tank 1. The temperature sensor is electrically connected to the control circuit of the resistance heating pipe 3.

[0036] Specifically, the discharging assembly 6 further includes a roller conveyor 610. The bottom of the frame of the roller conveyor 610 is connected to the inclined surface tray 7 by screws.

[0037] The advantages are as follows: When the steel pipes fall into the galvanizing tank 1 for galvanizing treatment, the discharging assembly 6 starts to work. Among them, the reduction motor 69 starts, driving the first shaft 62 to rotate. The first shaft 62 drives the first sprocket 63 to rotate. The first sprocket 63 cooperates with the second sprocket 66 to drive the chain 67 to rotate. The rotating chain 67 drives a plurality of L-shaped levers 68 to rotate. The rotating L-shaped levers 68 will gradually contact the steel pipes and pick them out of the galvanizing tank 1. Subsequently, the galvanized steel pipes will fall onto the roller conveyor 610, and the roller conveyor 610 can convey the galvanized steel pipes to the next drying process.

[0038] Specifically, one side of the inclined surface tray 7 relative to the roller conveyor 610 is welded to the outer surface of the galvanizing tank 1. The outer surface of the galvanizing tank 1 is penetrated with a reflux notch 8.

[0039] The advantages are that after the galvanized steel pipe is sent onto the roller conveyor 610, the zinc liquid remaining on the outer surface of the steel pipe will fall onto the inclined tray 7, and then the zinc liquid will fall into the return trough opening 8 along the inclined surface. Through the return trough opening 8, the zinc liquid can flow back into the galvanizing bath 1. On the one hand, the recycling of the zinc liquid realizes the circular utilization of resources, reduces the waste of zinc liquid, and lowers the production cost. On the other hand, it prevents the random dripping of zinc liquid from polluting the working site, meeting the environmental protection requirements.

[0040] During use, first place multiple steel pipes to be galvanized on the inclined surface of the bent rod 51. The bent rod 51 cooperates with the vertical baffle 58 to prevent the steel pipes from rolling, enabling multiple steel pipes to be placed at one time. Subsequently, start the motor of the driving component 510. The output shaft of the motor drives the first pulley to rotate. Through the synchronous belt, the second pulley rotates, and then drives the transmission rod 56 to rotate. The material distribution plate 59 on the transmission rod 56 rotates accordingly. The arc-shaped notch of the material distribution plate 59 catches one steel pipe each time. As the transmission rod 56 continues to rotate, the steel pipes are gradually driven from the bent rod 51 and fall into the galvanizing bath 1. The temperature sensor in the galvanizing bath 1 monitors the temperature in real time and is electrically connected to the control circuit of the resistance heating tube 3 to ensure that the temperature in the galvanizing bath 1 is appropriate. After the steel pipes are galvanized in the galvanizing bath 1, start the reduction motor 69 of the discharging component 6, which drives the first shaft 62 to rotate. The first shaft 62 drives the first sprocket 63 to rotate. The first sprocket 63 cooperates with the second sprocket 66 to drive the chain 67 to rotate. The rotating L-shaped lever 68 pulls the galvanized steel pipes out of the galvanizing bath 1 and makes them fall onto the roller conveyor 610. Subsequently, the roller conveyor 610 transports the galvanized steel pipes to the next drying process. At the same time, the zinc liquid remaining on the outer surface of the steel pipes falls onto the inclined tray 7 and then flows along the inclined surface into the return trough opening 8, flowing back into the interior of the galvanizing bath 1, realizing the circular utilization of resources and preventing pollution.

[0041] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
