After continuous research, design, and repeated prototype production and improvement, this utility model with real practical value has finally been created.
[0040] Please refer to Figure 1 This utility model provides an impurity collection device, including a discharge pipe section 1, an impurity collection tank 2, and an air blowing device.
[0041] The powder equipment outputs powder material through the discharge pipe section 1; the impurity collection tank 2 is installed on one side of the bottom of the discharge pipe section 1 to form a collection space 201; the opening of the impurity collection tank 2 is connected to the discharge pipe section 1, and the collection space 201 is lower than the discharge pipe section 1; the air blowing device is connected to the collection space 201 through the air pipe 31, and the air outlet end of the air pipe 31 is lower than the lowest point of the discharge pipe section 1.
[0042] In the actual production process, the powder material falls into the collection space 201 of the impurity collection tank 2 along the discharge pipe section 1. The air pipe 31 blows air into the collection space 201, so that the powder material is blown out of the collection space 201 and continues to be discharged into the discharge pipe section 1. Heavier impurity particles are not easily blown out, causing metal particles and other impurities to fall into the impurity collection tank 2.
[0043] The impurity collection device in this embodiment can effectively collect impurity particles such as metal particles and sand particles, effectively reduce the magnetic metal content of powder materials, and improve the purity of the output.
[0044] Optionally, the discharge pipe section 1 includes a vertical pipe 11 and a horizontal pipe 12, which are connected to form an L-shaped structure; the impurity collection tank 2 is located at the bottom end of the vertical pipe 11, and the opening of the impurity collection tank 2 is directly opposite the inner hole of the vertical pipe 11.
[0045] Specifically, the vertical pipe 11 is positioned directly opposite the impurity collection tank 2, allowing powder materials to fall directly into the impurity collection tank 2. Furthermore, powder materials blown out of the impurity collection tank 2 are less likely to be blown back into the manufacturing equipment from the vertical pipe 11. The vertical pipe 11 and the horizontal pipe 12 are connected to form an L-shaped structure, which better collects heavier impurity particles and improves the purity of the powder materials.
[0046] Optionally, the impurity collection tank 2 has a horizontal air inlet hole 202 on its wall, and the air pipe 31 is connected to the horizontal air inlet hole 202. It should be further noted that the airflow is blown horizontally into the impurity collection tank 2 along the horizontal air inlet hole 202, thereby reducing the possibility of blowing up the impurity particles at the bottom of the impurity collection tank 2, which helps to better prevent the impurity particles from re-entering the vertical pipe 11.
[0047] It should also be noted that the airflow is blown out horizontally along the horizontal air inlet 202, which can better agitate the powder material, making it easier for impurity particles to fall onto the bottom wall of the impurity collection tank 2.
[0048] It should be further noted that the airflow along the horizontal air inlet 202 should generally have a low velocity, ideally enough to move the powder material upwards but not to move impurity particles upwards. Generally, the airflow velocity along the horizontal air inlet 202 should not exceed 0.1 m / s.
[0049] Optionally, at least three horizontal air inlet holes 202 are arrayed on the wall of the impurity collection tank 2. All horizontal air inlet holes 202 are arranged in a circumferential array around the center line of the impurity collection tank 2, and the center lines of all horizontal air inlet holes 202 are located on the same horizontal plane. This allows the powder material to float more effectively and enter the discharge pipe section 1 with the airflow, moving in the discharge direction. The presence of multiple horizontal air inlet holes 202 can prevent the possibility of some powder material remaining in the dead corner of the impurity collection tank 2 without being blown away.
[0050] Alternatively, please refer to Figure 2 The material collection space 201 is divided into an upper space 2011 and a lower space 2012 located on one side of the bottom of the upper space 2011. A screen 2013 for supporting powder materials is provided between the upper space 2011 and the lower space 2012.
[0051] Specifically, impurity particles can pass through the mesh of screen 2013 and fall into the lower space 2012, while the powder material, due to its relatively large volume, will remain above screen 2013, thus preventing the floating powder material from re-adhering to impurity particles.
[0052] Optionally, the horizontal air inlet 202 is higher than the screen 2013 to avoid blowing out impurity particles.
[0053] Optionally, the blowing device includes a nitrogen storage unit and a control valve assembly connected to the nitrogen storage unit; the gas pipe 31 is connected to the control valve assembly. The nitrogen storage unit supplies nitrogen, and the control valve assembly controls the nitrogen outlet rate.
[0054] It should be noted that the gas blown out by the blowing device is an inert gas such as nitrogen to avoid oxidation-reduction reaction between the gas and the powder material.
[0055] Optionally, the bottom end of the vertical pipe 11 is connected to a first flange, and the impurity collection tank 2 is provided with a second flange for sealing connection with the first flange, thereby maintaining the sealing effect in the discharge pipe section 1 and reducing the possibility of oxidation of powder materials.
[0056] Optionally, the impurity collection tank 2 is detachably connected to the discharge pipe section 1. Therefore, the impurity collection tank 2 can be directly removed during maintenance, allowing for better removal of impurity particles.
[0057] Alternatively, please refer to Figure 3 The closer the collection space 201 is to the discharge pipe section 1, the larger the opening, so that the powder material can flow along the slope to the discharge pipe section 1 and eventually flow to the discharge pipe section 1. Preferably, the slope of the slope should not be too small, as this will easily cause impurity particles to accumulate on the slope, thereby affecting the collection effect of impurity particles and making it difficult to improve the discharge purity of the powder material.
[0058] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
