Referring to fig. 1 and 2, the embodiment of the present invention discloses an additive auxiliary agent circulation supply recovery device, including a storage bin 1 for storing a welding flux, a separator 2 for recovering and separating the welding flux, a separation bin 3 for storing the separated welding flux, a negative pressure pump set 4 for generating a negative pressure action on the separator 2, and a three-way head 5 for supplying and recovering the welding flux, wherein the three-way head 5 includes a first pipeline 501 for discharging and a second pipeline 502 for returning, the first pipeline 501 passes through the second pipeline 502, the upper end of the second pipeline 502 is sealed with the first pipeline 501, and the lower end face of the first pipeline 501 is higher than the lower end face of the second pipeline 502; the first pipeline 501 is communicated with the storage bin 1, and the second pipeline 502 is communicated with the separator 2; the separator 2 is communicated with the separation bin 3, the separator 2 is communicated with the storage bin 1, a first switch 6 is arranged at the outlet of the separation bin 3, and a second switch 7 is arranged at the outlet of the storage bin 1.

Wherein, the first switch 6 and the second switch 7 are controlled to be opened or closed by a controller (not shown in the figure); the welding torch head passes through the first conduit 501 and is fixed within the first conduit 501.

During surfacing, the first switch 6 is closed, the second switch 7 is opened, and the welding flux in the storage bin 1 continuously flows into the first pipeline 501 to provide the welding flux for the welding gun head; meanwhile, the flux remaining during the build-up welding process (i.e., the flux that has not been welded or the flux that has not reacted) is recovered through the second pipe 502 by the negative pressure pump unit 4. Since the separator 2 and the separation chamber 3 are kept at a negative pressure during the flux recovery process, the second switch 7 needs to be kept in a closed state. Wherein, a filter is arranged in the negative pressure pump group 4 to prevent dust from entering the negative pressure pump group under the action of negative pressure.

When the surfacing welding is not carried out, the controller controls the first switch 6 to be turned on according to the printed line distance; for example, when the actual printed line distance reaches the preset line distance, the controller controls the first switch 6 to be turned on to replenish the flux into the storage bin 1. In order to ensure the normal recovery of the flux, the replenishment of the flux in the storage silo 1 is therefore performed without surfacing, i.e. the first switch 6 is opened without surfacing.

In the embodiment of the present invention, as shown in fig. 2, the second pipeline 502 in the three-way head 5 is disposed outside the first pipeline 501, and the lower end surface of the first pipeline 501 is higher than the lower end surface of the second pipeline 502, so as to avoid affecting the printing of the welding position; moreover, the welding gun head is positioned at the center of the first pipeline 501, so that the second pipeline 502 is positioned around the welding flux, the residual welding flux at the welding position can be better and timely recovered, the welding gun head is very convenient to use, and the residual welding flux can be completely recovered.

Specifically, as shown in fig. 4 and 5, the first switch 6 includes a valve seat 601, a cylinder 602 and a valve cover 603, wherein the valve seat 601 is arranged at the bottom of the separation chamber 3; an outlet cavity 6011 for discharging is arranged in the valve seat 601, and the outlet cavity 6011 penetrates out of the separation bin 3 and is introduced into the storage bin 1; a valve cover 603 is provided at a lower end of the outlet chamber 6011 to seal an outlet of the outlet chamber 6011; a fixing seat 6012 for fixing the air cylinder 602 is arranged above the outlet cavity 6011, a piston rod 6021 of the air cylinder 602 penetrates through the outlet cavity 6011 to be connected with the valve cover 603, and the air cylinder 602 drives the valve cover 603 to lift by driving the piston rod 6021, so that an outlet 60111 of the outlet cavity 6011 is controlled to be opened and closed.

Wherein the cylinder 602 may be controlled by a controller. Specifically, the controller controls the lifting and lowering of the piston rod 6021 in the cylinder 602 by the printed line distance, so as to control the opening and closing of the outlet 60111 of the outlet chamber 6011. For example, when the line distance of the actual printing reaches the preset printing distance, the air cylinder 602 controls the valve cover 603 to descend to open the outlet 60111 of the outlet chamber 6011, and the flux may be replenished from the outlet chamber 6011 into the storage silo 1 to ensure continuous printing.

Further, a conical surface seal is formed between the valve cover 603 and the outlet 60111 of the outlet chamber 6011, wherein the diameter of the conical surface seal is gradually reduced from bottom to top, so that in the process of closing the outlet 60111 of the outlet chamber 6011, the contact surface between the valve cover 603 and the outlet 60111 of the outlet chamber 6011 is gradually narrowed; under the action of a certain sealing force, the specific sealing pressure of the seal is greatly increased, and the sealing effect is easily achieved; therefore, when the valve cover 603 rises, the separator 2 and the separation bin 3 are kept in a negative pressure state under the action of the negative pressure pump group 4, so that the recovery of the welding flux in the printing process is ensured.

In addition, because the conical surface is used for sealing, when the valve cover 603 is used for sealing the outlet cavity 6011, the conical surface can play a guiding role for the valve cover 603; when the valve cover 603 is guided in the outlet chamber 6011, the side thrust of the particulate auxiliary agent received by the valve cover 603 is received by the outlet chamber 6011 instead of the valve cover 603, thereby further enhancing the reliability of the sealing property and the packing sealing property.

Further, a copper ring sleeve 604 is arranged at the lower end of the outlet cavity 6011, and conical surface sealing is achieved between the copper ring sleeve 604 and the valve cover 603. By using the copper collar 604, the sealing between the valve cover 603 and the outlet chamber 6011 is enhanced.

Further, the inlet 60112 of the outlet chamber 6011 is in a funnel shape, and plays a guiding role for the auxiliary agent.

Further, as shown in fig. 3, the separator 2 is provided with an inclined surface 201, and a connection pipe communicating with the second pipe 502 is provided on the inclined surface 201 so that the flux recovered to the separator 2 can have a buffer area.

Wherein, the front of the inclined surface 201 is provided with a baffle 202, and a channel 203 is formed between the baffle 202 and the inclined surface 201; the upper part of the channel 203 is communicated with the negative pressure pump group 4, and the lower part of the channel 203 is communicated with the separation chamber 3. The special airflow channel 203 is formed by the inclined surface 201 and the baffle plate 202, so that the device of the separator 2 can be reduced, the separator 2 can be more compact, and the recovery of the welding flux is ensured.

Further, the side wall of the storage bin 1 is provided with a vent hole 101 to prevent negative pressure from being formed in the storage bin 1 during the flux supply process, thereby affecting the flux supply.

In summary, the three-way head 5 of the present invention comprises a first pipeline 501 for discharging and a second pipeline 502 for returning, wherein the welding gun head passes through the first pipeline 501, so that the flux can be continuously supplied by controlling the second switch 7 during the build-up welding; meanwhile, the residual flux on the surface of the welding part is recovered through the second pipeline 502 under the action of the negative pressure pump set 4, and enters the separation bin 3 after being separated in the separator 2; the flux in the separator 2 can be timely supplemented into the storage bin 1 through the first switch 6, so that the additive manufacturing work of the auxiliary agent can be continuously carried out. The utility model discloses in can guarantee can supply in succession and retrieve the solder flux in the additive manufacturing, simple structure and convenient to use.
