[0033] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] like Figures 1-3As shown, one embodiment of the present invention provides a welding machine water supply device for supplying water to a welding machine, including a first filtration mechanism, a transport pipeline and at least one water storage tank 1;

[0035] The first filtration unit has an inlet and an outlet. The inlet of the first filtration unit is used to connect to an external water source, and its outlet is connected to the inlet of the transport pipeline.

[0036] The outlet of the transport pipeline is connected to the inlet of the water storage tank 1, and the outlet of the water storage tank 1 is connected to the nozzle of the welding machine.

[0037] Water storage tank 1 and welding machine correspond one-to-one.

[0038] The first filtration mechanism filters out impurities from the water, allowing high-purity water to be transported through the pipeline to the water storage tank 1. From there, the water is transported to the welding nozzle, preventing the nozzle from clogging. The combination of the first filtration mechanism and the pipeline allows external water to be delivered to the corresponding water storage tank 1 without the need for manual water bucket replacement, saving manpower and improving production efficiency.

[0039] According to one embodiment of the present invention, a second filtration mechanism for filtering clean water is provided between the water storage tank 1 and the nozzle of the welding machine.

[0040] The second filtration mechanism can perform secondary filtration on the water in the water storage tank 1, making the water source purer and less likely to clog the welding machine nozzle.

[0041] According to one embodiment of the present invention, the first filtration mechanism includes a sand filter tank 2, an activated carbon filter 3, a softened water filter 4, a security filter 5, a first water pump 6, and a reverse osmosis membrane filter 7 connected in sequence.

[0042] The transport pipeline includes branch pipe 8;

[0043] Sand filter tank 2 is used to filter large particulate impurities in clean water;

[0044] The outlet of the reverse osmosis membrane filter 7 is connected to the inlet of the water storage tank 1 through the branch pipe 8, and the water storage tank 1 and the branch pipe 8 correspond one-to-one.

[0045] The second outlet of the reverse osmosis membrane filter 7 is used to discharge wastewater.

[0046] The sand filter tank 2 performs preliminary filtration of large particulate impurities in the water. The activated carbon filter 3 adsorbs organic matter, residual chlorine, odors, and some heavy metals from the water, further filtering the water. The security filter 5 effectively intercepts small particulate impurities, preventing damage and protecting the reverse osmosis membrane filter 7. The reverse osmosis membrane filter 7 removes most dissolved salts, small molecule organic matter, bacteria, and viruses from the water, producing high-purity water. This makes the welding nozzle less prone to clogging or corrosion, extending its service life.

[0047] In addition, by using the water storage tank 1, when the external water source is interrupted or the first filter needs to be replaced, the remaining clean water in the water storage tank 1 can continue to supply water, without affecting the normal operation of the welding machine and improving production efficiency.

[0048] The welding machine water supply device also includes a controller. A pressure sensor is installed on the branch pipe 8. When the water supply pressure reaches 2KG, the pressure sensor sends a signal to the controller, which then controls the first water pump 6 to shut down and stop the water supply, thus achieving a rapid water replenishment function and preventing water supply interruption.

[0049] It should be noted that there are multiple welding machines, and the transport pipeline includes a main pipeline and multiple branch pipes 8. After the clean water is transported from the reverse osmosis membrane filter 7, it is delivered to the main pipeline, and the main pipeline transports the water to the multiple branch pipes 8 respectively. The water storage tank 1 is connected to the first filter 9 through a third water pipe, and a second water pump is installed on the third water pipe.

[0050] According to one embodiment of the present invention, the second filtration mechanism includes a first filter 9, a first connecting pipe 10, a filter assembly 11, a second connecting pipe 12, and a second filter 13 connected in sequence.

[0051] The filter assembly 11 includes a housing with an opening at the top. The outlet of the first connecting pipe 10 passes through the opening and is located inside the housing. The inlet of the second connecting pipe 12 passes through the opening and is located inside the housing. The outlet of the first connecting pipe 10 is lower than the inlet of the second connecting pipe 12. A far-infrared sterilizer is installed on the bottom wall of the housing.

[0052] The far-infrared sterilizer can disinfect some bacteria in the water, reduce the amount of bacteria in the water, improve the purity of the water, and prevent bacteria from multiplying and clogging the welding machine nozzle.

[0053] The first filter 9, the second filter 13, and the filter assembly 11 can filter clean water to form pure water, which is then delivered to the welding machine nozzle, thus making the welding machine nozzle less prone to clogging.

[0054] According to one embodiment of this utility model, the second filter 13 is connected to the nozzle of the welding machine via a third connecting pipe 15, and a water quality detector 14 for detecting water quality is installed on the third connecting pipe 15. A third water pump is installed on the third connecting pipe 15. The water storage tank 1 can be placed on the side of the welding machine or on top of the welding machine.

[0055] The water quality detector 14 can detect the purity of the water flowing from the welding machine nozzle. Higher purity indicates better filtration. When the water purity detected by the water quality detector 14 falls below its set threshold, the entire water supply system is shut down, and a new filter is installed. The water quality detector 14 is existing technology and will not be described in further detail.

[0056] According to one embodiment of the present invention, a water level sensor for detecting the liquid level inside the housing is provided inside the housing, and the water level sensor is located at the outlet end of the first connecting pipe 10. The outlet end of the first connecting pipe 10 includes the outlet of the first connecting pipe 10 and a portion of the pipe body of the first connecting pipe 10 located inside the housing.

[0057] It should be noted that the water level sensor is used to detect the water level inside the casing and keep the water level above the inlet of the second connecting pipe 12, so that the second connecting pipe 12 can always supply water normally.

[0058] According to one embodiment of the present invention, the sand filter tank 2 is a variable diameter sand filter tank. The sand filter tank 2 facilitates the installation of the first fixing ring plate 201 and the second fixing ring plate 205.

[0059] According to one embodiment of the present invention, along the direction from the top to the bottom of the sand filter tank 2, the sand filter tank 2 is provided with at least a first chamber and a second chamber whose diameters decrease sequentially.

[0060] A first fixed ring plate 201 is fixedly connected to the first chamber, and a first filter plate 202 is detachably connected to the first fixed ring plate 201.

[0061] A second fixed ring plate 205 is fixedly connected to the second chamber, and a second filter plate 206 is detachably connected to the second fixed ring plate 205.

[0062] The sand filter tank 2 has an inlet at the top and an outlet on the bottom side wall. The inlet at the top of the sand filter tank 2 is connected to an external water source through a first water pipe, and the outlet at the bottom is connected to the activated carbon filter 3 through a second water pipe.

[0063] Preferably, the sand filter tank 2 may further include a third chamber. The first, second, and third chambers are interconnected. A third fixed ring plate is fixedly connected to the third chamber, and a third filter plate is connected to the third fixed ring plate by locking bolts. The number of chambers in the sand filter tank 2 is the same as the number of layers of filter media inside it. Each filter plate is used to separate the filter media.

[0064] According to one embodiment of the present invention, the diameter of the second filter plate 206 is smaller than the inner diameter of the first fixed ring plate 201 and larger than the inner diameter of the second fixed ring plate 205.

[0065] The filter holes in the first filter plate 202, the second filter plate 206, and the third filter plate all cover the entire plate surface, and the pore sizes of the filter holes in the first filter plate 202, the second filter plate 206, and the third filter plate are all different.

[0066] Of course, in this embodiment, the second filter plate 206 can also be removed in other ways. For example, the second filter plate 206 can also be a first arc plate and a second arc plate that are snapped together. The first arc plate is connected with a snap block, and the second arc plate is provided with a snap groove. After the first arc plate and the second arc plate are placed into the second chamber, the snap block is inserted into the snap groove and they are spliced ​​together to form a circular filter plate. Alternatively, the second filter plate 206 can be installed on the second fixing ring plate 205. Similarly, the third filter plate has the same structure. Its purpose has not deviated from the design concept of this utility model. Therefore, it should fall within the protection scope of this utility model.

[0067] According to one embodiment of the present invention, a first connecting rod 204 is provided inside the sand filter tank 2, and a first groove 203 is symmetrically provided on the first fixing ring plate 201. The two ends of the first connecting rod 204 are respectively located in the first groove 203, and the upper surface of the first connecting rod 204 and the upper surface of the first fixing ring plate 201 are located on the same horizontal plane.

[0068] Of course, in this embodiment, the first connecting rod 204 can also be cross-shaped, and four first grooves 203 are evenly provided around the axis of the first fixing ring plate 201, so that the four ends of the cross-shaped first connecting rod 204 are respectively located in the corresponding first grooves 203, and its support effect is better. Its purpose has not departed from the design concept of this utility model, therefore, it should fall within the protection scope of this utility model.

[0069] The first connecting rod 204 provides better support for the first filter plate 202, making it less likely for the first filter plate 202 to deform downwards due to the filter material. The first groove 203 makes the first connecting rod 204 a detachable rod, which does not affect the subsequent disassembly and assembly of the second filter plate 206 and the third filter plate.

[0070] Furthermore, a limiting groove is provided on the first fixed ring plate 201, and a limiting block adapted to the limiting groove is provided on the first filter plate 202. When the first filter plate 202 is placed on the first fixed ring plate 201, the limiting block is inserted into the corresponding limiting groove for initial positioning. After positioning, it is locked by locking bolts. The limiting block and limiting groove can also prevent the first filter plate 202 from being subjected to force due to filter media and water flow, thus preventing the locking bolts from loosening slightly and improving the connection stability.

[0071] According to one embodiment of the present invention, the first fixing ring plate 201 and the first filter plate 202 are connected by a plurality of locking bolts.

[0072] Specifically, the first fixing ring plate 201 has a screw hole, and the first filter plate 202 has a through hole. The locking bolt passes through the through hole and screws into the screw hole, thereby fixing the first filter plate 202 onto the first fixing ring plate 201.

[0073] It should be noted that the sand filter tank 2 includes a tank body and a tank cover connected by bolts. First, a third connecting rod is installed on the third fixed ring plate. Then, the third filter plate is bolted to the third fixed ring plate and the first type of filter material is laid on the upper side of the third filter plate. Next, a second connecting rod and a second filter plate 206 are installed and the second type of filter material is laid on the second filter plate 206. Finally, a first connecting rod and a first filter plate 201 are installed and the third type of filter material is laid on the first filter plate 201.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0075] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
