[0083] Further, if Figure 1 , 2As shown in , 5~7, the stirring module also includes: a plurality of groups of guide protrusions 55 and a plurality of groups of air flow channels (not shown in the figure); a plurality of groups of guide protrusions 55 are fixedly arranged on the circumferential inner wall of the furnace body 1, and a plurality of groups of guide protrusions 55 correspond to the positions of a plurality of stirring paddles 53 one by one, and any group of guide protrusions 55 is composed of a plurality of guide protrusions 55, and the tail end of any guide protrusion 55 is inclined toward the bottom wall of the inner cavity of the furnace body 1, so as to guide the stirring paddle 53; a plurality of groups of air flow channels are respectively opened inside the plurality of guide protrusions 55, and the output end of any air flow channel is exposed to the tail end surface of the corresponding guide protrusion 55, and the input end of any air flow channel is connected to the interlayer 12 of the furnace body 1, and the output end of the air inlet interface 2 is connected to the bottom of the inner cavity of the interlayer 12, and the heating device 13 of the furnace body 1 is arranged in the interlayer 12.

[0084] The working principle of this device is as follows:

[0085] Before the operation of the device, the user starts the inert gas generating device, injects inert gas with a density greater than that of air into the interlayer 12 of the furnace body 1 through the air inlet interface 2, and allows the gas to pass through the interlayer 12 of the melting furnace and the air flow channel into the inner cavity of the furnace body 1 in turn. As the amount of inert gas in the inner cavity of the furnace body 1 increases, the air in the inner cavity of the furnace body 1 is discharged through the air outlet valve 3 until the inert gas fills the inner cavity of the furnace body 1. In this process, the inert gas can bring the heat in the interlayer 12 into the inner cavity of the furnace body 1; after the furnace body 1 is filled with the inert gas, the user opens the top cover 11, and puts the alloy powder and antioxidant into the inner cavity of the furnace body 1 through the top port of the furnace body 1; after the user puts the alloy powder and antioxidant into the inner cavity of the furnace body 1, the alloy powder and antioxidant with particle size meeting the standard fall to the bottom of the inner cavity of the furnace body 1 through the sieve holes of the sieve plate 41.

[0086] When the device is running, the motor 4751 of the driving mechanism 475 drives the driving gear 4753 to rotate, so that the driving gear 4753 drives the driven gear 4752 to rotate, and then drives the driving hollow shaft 474 to rotate. Since the bottom end of the driving hollow shaft 474 is fixedly connected to the transmission ring body 472, during the rotation of the driving hollow shaft 474, the driving hollow shaft 474 will drive the transmission ring body 472, the plurality of paddle plates 473 and the bearing ring body 471 to rotate synchronously. During the rotation of the plurality of paddle plates 473, the plurality of paddle plates 473 push the alloy powder and the antioxidant in the gaps between the plurality of paddle plates 473. The agent is displaced on the upper surface of the sieve plate 41, and the agglomerated alloy powder or antioxidant is ground by a plurality of grinding teeth 42 arranged on the upper surface of the sieve plate 41, so that the alloy powder and antioxidant with particle size meeting the standard fall to the bottom of the inner cavity of the furnace body 1 through the sieve holes of the sieve plate 41; in the process of synchronous rotation of the transmission ring body 472 and the plurality of paddle plates 473, the transmission ring body 472 drives the plurality of driven bevel gears 4762 to rotate synchronously, and since the driven bevel gear 4762 is meshed with the active bevel gear 4763, the plurality of driven bevel gears 4762 drives the active bevel gear 4763 to rotate synchronously, and in this process, the ratchet device 4761 rotates idly.

[0087] The user can expand the slit width between the paddle plates 473 by adjusting the deflection angles of the paddle plates 473, so that a larger volume of agglomerated alloy powder or agglomerated antioxidant can pass through the slits between the paddle plates 473 and enter the cavity between the paddle plates 473 and the screen plate 41, and be pushed to move on the upper surface of the screen plate 41 during the rotation of the paddle plates 473, and then be ground by the grinding teeth 42.

[0088] The process of adjusting the deflection angles of the plurality of paddles 473 is as follows: the first driving device 46 drives the first main shaft 44 and the active hollow shaft 474 to rotate in the same direction, and makes the rotation speed of the first main shaft 44 greater than the rotation speed of the active hollow shaft 474. During the rotation of the first main shaft 44, the first main shaft 44 drives the ratchet device 4761 to rotate in the same direction, and the ratchet mechanism is used for power transmission to drive the active bevel gear 4763 to rotate in the same direction. Since the rotation speed of the first main shaft 44 is greater than the rotation speed of the active hollow shaft 474, During the rotation of the active bevel gear 4763, the active bevel gear 4763 drives several driven bevel gears 4762 to rotate, thereby adjusting the deflection angles of several paddle plates 473, and since the bottom end of the first main shaft 44 is threadedly connected to the screw hole, during the rotation of the first main shaft 44, the sieve plate 41 is driven by the first main shaft 44 to move toward the bottom wall of the inner cavity of the furnace body 1, thereby expanding the width of the slit between the paddle plate 473 and the sieve plate 41 for the flipping of several paddle plates 473.

[0089] During the synchronous rotation of the plurality of paddle plates 473, the larger agglomerated alloy powder or antioxidant cannot enter the cavity between the paddle plate 473 and the sieve plate 41 through the slits between the plurality of paddle plates 473, and thus cannot contact the grinding teeth 42 to be ground. For such agglomerated alloy powder, the paddle plate 473 will drive it to move with the paddle plate 473 during the rotation, so that it will be smashed by the stirring short rod 48 arranged between the sieve plate 41 and the top cover 11 during the movement, until its volume meets the requirement of passing through the slits between the plurality of paddle plates 473; in another embodiment of the present invention, the stirring short rod 48 is an elastic member, and each paddle plate 473 continuously moves the bottom ends of the plurality of stirring short rods 48 during the rotation process, so that they undergo elastic deformation. After the paddle plate 473 is separated from the bottom end of the current stirring short rod 48, the stirring short rod 48 resumes its deformation, thereby crushing the agglomerated alloy powder located on the side of the bottom end of the stirring short rod 48.

[0090] While the crushing module of the device is running, the stirring module is running synchronously to mix the alloy powder and the antioxidant that fall between the sieve plate 41 and the bottom wall of the inner cavity of the furnace body 1 evenly. The stirring module includes the following two working modes:

[0091] Working mode one, when the stirring module is running, the third driving device 548 drives the second main shaft 51 to rotate, so that the second main shaft 51 drives the transmission hollow shaft 52 to rotate, and then the transmission hollow shaft 52 drives several stirring paddles 53 to rotate synchronously. During the rotation of the stirring paddles 53, the alloy powder and antioxidant in the cavity between the sieve plate 41 and the bottom wall of the inner cavity of the furnace body 1 are mixed evenly.

[0092] Working mode 2: When the stirring module is running, the second driving device 545 drives the handle to rotate, so that the handle drives the turbine to rotate. During the rotation of the turbine, the threaded assembly relationship between the first thread 5421 and the second thread is used to drive the lifting cylinder 542 to rise along the guide groove 5422, thereby driving the second main shaft 51 and the transmission hollow shaft 52 to rise synchronously, so that the stirring paddle 53 interferes with the guide protrusion 55 during the rotation process. During the rotation of the stirring paddle 53, when the end of the stirring paddle 53 contacts the guide protrusion 55, the stirring paddle 53 is affected. The downward pressure from the guide protrusion 55 drives the transmission hollow shaft 52 to move downward a distance, compressing the reset elastic member 547. After the end of the stirring paddle 53 is separated from the tail end of the guide protrusion 55, the pressure from the guide protrusion 55 on the end of the stirring paddle 53 disappears, and the reset elastic member 547 releases the elastic force, driving the transmission hollow shaft 52 and several stirring paddles 53 to rise, thereby lifting the alloy powder and the antioxidant upward, enhancing the stirring effect of the stirring paddle 53 on the alloy powder and the antioxidant, and allowing the alloy powder to be heated on multiple sides.

[0093] Above, refer to Figures 1 to 7 The alloy powder heat treatment device according to the embodiment of the present invention is described, which has the following beneficial effects:

[0094] 1. The device is connected to an inert gas generating device by arranging an air inlet interface on the furnace body, and an air outlet valve is arranged on the top cover, so that the inert gas generating device can input an inert gas with a density greater than that of air into the inner cavity of the furnace body through the air inlet interface, and discharge the air in the inner cavity of the furnace body through the air outlet valve, thereby reducing the oxygen content in the furnace body during the heat treatment of the alloy powder, so as to solve the technical problem in the prior art that the alloy powder is easily oxidized during the heat treatment of the alloy powder.

[0095] 2. The crushing module of the device is provided with a plurality of pulp plates with adjustable deflection angles, so that it can cooperate with the grinding teeth to crush agglomerated alloy powders and antioxidants of different volumes. In addition, the crushing module of the device is provided with a first main shaft, a transmission mechanism, a guide mechanism and a screw hole, and utilizes the threaded assembly relationship between the first main shaft and the screw hole to enable the first main shaft to drive the transmission mechanism to operate, increase the deflection angle of the pulp plate and drive the screen plate to descend synchronously, thereby providing sufficient deflection space for the plurality of pulp plates, eliminating the need for an additional power device to drive the screen plate to cooperate and move, thereby reducing the assembly volume of the device.

[0096] 3. The stirring module of the device is provided with a driving assembly and a guide module, so that the third driving device drives the stirring paddle to rotate. In the process of stirring the alloy powder, the guiding protrusion presses the stirring paddle downward, so that the reset elastic part can drive several stirring paddles to jump upward in the process of releasing the elastic force, thereby lifting the alloy powder upward and heating multiple sides, further enhancing the heat treatment effect of the device on the alloy powder.
