DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] Reference Figure 1-Figure 5 A filtering device for bismuth alloy powder particles comprises a screening box 1 and a discharge port 3 provided on one side of the screening box 1. A screening component 2 for screening bismuth alloy powder is provided inside the screening box 1. When the device is used, the produced bismuth alloy powder is first put into the screening box 1, and then screened by the screening component 2 provided in the screening box 1, so as to separate unqualified particles therein, thereby ensuring the progress of subsequent work;

[0024] The screening component 2 includes a screening frame 21 slidably mounted inside the screening box 1, a screening filter 22 is provided in the screening frame 21, a screening cavity 23 is formed between the screening filter 22 and the bottom of the screening frame 21, a driving component 24 for controlling the movement of the screening frame 21 is provided at the bottom of the screening box 1, and a blocking component 25 for blocking the screening frame 21 is provided at one end of the screening frame 21. The bismuth alloy powder entering the screening box 1 will first fall into the screening frame 21. In this embodiment, the bismuth alloy powder can be filtered by the screening filter 22 provided on the upper part of the screening frame 21, and the driving component 24 provided inside the screening box 1 can drive the screening frame 21 to move back and forth in the screening box 1, thereby achieving the purpose of promoting the separation of the bismuth alloy powder. Figure 2 As shown, the screening filter 22 is tilted, so the bismuth alloy powder on the screening filter 22 will move downward under the action of its own gravity. When the screening frame 21 moves to a position close to the discharge port 3, the blocking component 25 can be opened to allow the filtered bismuth alloy powder and impurities to be discharged from the two discharge ports 3 respectively, thereby completing the filtering and separation operation of the bismuth alloy powder.

[0025] The driving assembly 24 includes a driving motor 241 fixedly mounted on the bottom of the screening box 1, an eccentric wheel 242 is coaxially fixed to the output end of the driving motor 241, and a driving connecting rod 243 hinged to the screening frame 21 is rotatably mounted on the upper part of the eccentric wheel 242. When this embodiment is implemented, the eccentric wheel 242 can be driven to rotate by starting the driving motor 241. Since the driving connecting rod 243 hinged to the screening frame 21 is provided on the upper part of the eccentric wheel 242, the movement of the eccentric wheel 242 will drive the screening frame 21 to reciprocate in the screening box 1, thereby achieving the effect of promoting the separation and filtration of the bismuth alloy powder.

[0026] Embodiment 2

[0027] Reference Figure 1-Figure 5 This embodiment is basically the same as the first embodiment, and is more optimized in that a vibration assembly 26 for controlling the vibration of the screening frame 21 is provided at the bottom of the screening frame 21, and the vibration assembly 26 includes a vibration gear 261 rotatably installed inside the screening box 1, and a vibration blade 263 that hits the bottom of the screening frame 21 is coaxially fixed to one side of the vibration gear 261, and a vibration rack 262 meshing with the vibration gear 261 is provided at the bottom of the screening frame 21. When the screening frame 21 moves, the vibration rack 262 provided at the bottom thereof will drive the vibration blade 263 to rotate by meshing with the vibration gear 261. When the vibration blade 263 moves, its outer portion will continuously hit the bottom of the screening frame 21, causing the screening frame 21 to vibrate, thereby further improving the filtering effect of the bismuth alloy powder.

[0028] A guide groove 28 is provided on the inner wall of the screening box 1, and guide blocks 27 slidably connected to the guide groove 28 are fixedly installed on both sides of the screening frame 21. The setting of the guide groove 28 and the guide block 27 plays a role in limiting and guiding the movement of the screening frame 21 in the screening box 1, thereby avoiding the probability of the screening frame 21 being offset during movement and improving the stability of the movement of the screening frame 21.

[0029] The blocking assembly 25 includes an operating chamber 251 provided on one side of the screening frame 21, a blocking plate 252 is slidably installed inside the operating chamber 251, a blocking spring 255 is provided on the upper part of the blocking plate 252, one end of which is fixedly connected to the upper part of the operating chamber 251, a sliding chamber 253 communicating with the operating chamber 251 is provided on the outside of the screening box 1, a transmission protrusion 254 fixedly connected to the blocking plate 252 is slidably installed inside the sliding chamber 253, and a cone plate 256 that contacts the transmission protrusion 254 is fixedly installed on the inner wall of the screening box 1 and near the discharge port 3. Under normal conditions, the blocking The blocking plate 252 will block the screening frame 21 under the action of the blocking spring 255 to prevent the bismuth alloy powder and large particles from escaping therefrom. Since the screening filter 22 is arranged at an angle, the separated bismuth alloy powder and large particles are mostly gathered at the blocking plate 252 during the filtration process. When the screening frame 21 moves to the discharge port 3, the cone plates 256 arranged on both sides of the discharge port 3 will drive the blocking plate 252 to rise by squeezing the transmission protrusion 254, so that the bismuth alloy powder and large particles can flow out from the two discharge ports 3 respectively, completing the screening operation.

[0030] How it works

[0031] When the device is used, the produced bismuth alloy powder is first put into the screening box 1, and then screened by the screening component 2 arranged in the screening box 1, so as to achieve the function of separating unqualified particles therein, ensuring the progress of subsequent work. The bismuth alloy powder entering the screening box 1 will first fall into the screening frame 21. In this embodiment, the screening filter 22 arranged on the upper part of the screening frame 21 can filter the bismuth alloy powder. At the same time, the driving component 24 arranged inside the screening box 1 can drive the screening frame 21 to move back and forth in the screening box 1, so as to achieve the purpose of promoting the separation of the bismuth alloy powder. Figure 2 As shown, the screening filter 22 is tilted, so the bismuth alloy powder on the screening filter 22 will move downward under the action of its own gravity. When the screening frame 21 moves to a position close to the discharge port 3, the blocking component 25 can be opened to allow the filtered bismuth alloy powder and impurities to be discharged from the two discharge ports 3 respectively, thereby completing the filtering and separation operation of the bismuth alloy powder. When the screening frame 21 moves, the vibration rack 262 arranged at the bottom thereof will drive the vibration blade 263 to rotate by engaging the vibration gear 261. When the vibration blade 263 moves, its outer portion will continuously hit the bottom of the screening frame 21, causing the screening frame 21 to vibrate, thereby further improving the filtering effect of the bismuth alloy powder. The setting of the guide groove 28 and the guide block 27 plays a role in limiting and guiding the movement of the screening frame 21 in the screening box 1, thereby avoiding the probability of the screening frame 21 being offset during movement and improving the stability of the movement of the screening frame 21.
