Description

Technical Field

[0001] The utility model relates to the technical field of flux dipping and coating devices, and more specifically to a flux continuous stirring and dipping and coating device. Background Art

[0002] Flux is a granular welding material. During welding, it can melt to form slag and gas, which can protect the molten pool and perform metallurgical treatment. During welding, it can melt to form slag and gas, which can protect the molten metal and perform metallurgical treatment. Submerged arc flux used for submerged arc. At present, most of the welding fluxes for air conditioners and automobile air conditioning systems are applied by spraying or dipping. Dipping is used for products that need to be welded on the inner and outer surfaces of round tubes and the ends of holes. Generally, the flux is placed in a container and the workpiece is dipped in the flux. Because the flux is composed of powder and liquid substances, the solution is easy to precipitate, the composition is uneven, and the flux is easy to stratify, resulting in uneven thickness and weight of the coating, which reduces the welding quality and welding reliability. The temperature of the dip flux is also very important. If it exceeds a certain temperature, the flux will fail. Utility Model Content

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figures 1 to 5 shown, the present utility model provides a flux continuous stirring and dipping device, including a flux pool 1, a motor 2 is fixedly connected to the right side of the flux pool 1, a fixing part 4 is fixedly connected inside the flux pool 1, a submersible pump 3 is fixedly connected inside the fixing part 4, a first conveying pipe 5 is fixedly connected to the rear side of the submersible pump 3, a conveying and reflux four-way assembly 6 is fixedly connected to the upper end of the first conveying pipe 5, a second conveying pipe 7 is fixedly connected to the upper end of the conveying and reflux four-way assembly 6, a nozzle 8 is fixedly connected to the left end of the second conveying pipe 7, a first reflux pipe 9 is fixedly connected to the right end of the nozzle 8, a second reflux pipe 10 is fixedly connected to the lower end of the conveying and reflux four-way assembly 6, a cooling component 11 is fixedly connected to the right end of the second reflux pipe 10, a third reflux pipe 12 is fixedly connected to the right end of the cooling component 11, a reflux liquid level measurement and control device 13 is fixedly connected to the right end of the third reflux pipe 12, and a bottom valve 14 is fixedly connected to the left end of the flux pool 1.

[0021] The flux circulation structure composed of the submersible pump 3, the first conveying pipe 5, the conveying and reflux four-way assembly 6, the second conveying pipe 7, the first reflux pipe 9, the second reflux pipe 10, the cooling component 11, the third reflux pipe 12 and the reflux liquid level measurement and control device 13 ensures that cooling circulation can be carried out during the flux dipping process. The flow of the flux in the circulation structure is beneficial to ensuring that the flux maintains a uniform mixing state, ensuring the consistency and stability of the flux, and the cooling by the cooling component 11 is beneficial to ensuring that the flux will not have too high a temperature resulting in flux instability.

[0022] Among them, the output end of the motor 2 is fixedly connected with three fan blades.

[0023] The fan blades stir the flux inside the flux pool 1 to ensure that the flux maintains a uniform mixing state, ensuring the consistency and stability of the flux.

[0024] Among them, the height value of the reflux liquid level measurement and control device 13 from the internal ground of the flux pool 1 is higher than the height value of the position where the submersible pump 3 is located.

[0025] The reflux liquid level measurement and control device 13 can more effectively ensure the maintenance of the flux amount inside the flux pool 1, ensure the circulation of the flux, and reduce the possibility that the pipeline cannot flow due to the blockage of the reflux liquid level measurement and control device 13 by the flux inside the flux pool 1.

[0026] Among them, the upper and lower ends of the conveying and reflux four-way assembly 6 each have two interfaces, which are respectively connected to the first conveying pipe 5, the second conveying pipe 7, the first reflux pipe 9, and the second reflux pipe 10.

[0027] Ensure the circulation of the flux inside the first conveying pipe 5, the second conveying pipe 7, the first reflux pipe 9, and the second reflux pipe 10, and increase the connectivity of the pipeline.

[0028] Among them, the part of the first conveying pipe 5 leading to the conveying and reflux four-way assembly 6 is a check valve, the part of the second conveying pipe 7 leading to the spray head 8 is a check valve, the part of the first reflux pipe 9 leading to the conveying and reflux four-way assembly 6 is a check valve, and the part of the second reflux pipe 10 leading to the cooling assembly 11 is a check valve.

[0029] It can ensure that there is no reverse flow phenomenon when the flux passes through the conveying and reflux four-way assembly 6 and is sprayed out by the spray head 8, ensure that the fluid flow direction can be controlled, prevent backflow, simplify the pipeline design, and increase the safety of the system.

[0030] Among them, the inner walls at the left and right ends of the cooling assembly 11 are both hollow grooves, which are respectively connected to the second reflux pipe 10 and the third reflux pipe 12. The hollow grooves inside the cooling assembly 11 are connected by a spiral cooling pipe. The upper end of the cooling assembly 11 is fixedly connected with a water inlet, and the lower end of the cooling assembly 11 is fixedly connected with a water outlet.

[0031] Coolant can be added through the water inlet and water outlet holes of the cooling assembly 11, so that the flux can be cooled by the coolant inside the cooling assembly 11 when passing through the hollow grooves and the spiral cooling pipe, ensuring that the flux will not overheat and lose its effect at an appropriate temperature.

[0032] The working principle and usage process of the present utility model:

[0033] When welding is required, it is necessary to dip the flux. First, the flux is prepared inside the flux pool 1. After preparation, the motor 2 is started to continuously stir the flux to ensure its uniform mixing state and guarantee the consistency and stability of the flux. Then, the submersible pump 3 is started. The flux flows through the submersible pump 3 to the first conveying pipe 5 and then to the conveying and reflux four-way assembly 6. Then, it flows through the conveying and reflux four-way assembly 6 to the second conveying pipe 7. After reaching the second conveying pipe 7, it is sprayed through the nozzle 8 to dip the material with the flux. When the dipping stops, the flux will flow through the first reflux pipe 9 to the conveying and reflux four-way assembly 6, then enter the second reflux pipe 10, and then enter the cooling assembly 11. It stays in the hollow groove at the left end of the cooling assembly 11 and is then cooled through the spiral cooling pipe. Then, it enters the third reflux pipe 12 through the hollow groove at the right end and flows to the reflux liquid level measurement and control device 13, and returns to the inside of the flux pool 1. Cooling the flux ensures that the flux will not react due to the accumulated heat during long-term operation and stirring, reducing its activity.
