Description

Technical Field

[0001] This utility model relates to the field of screening device technology, specifically a screening device for powdered alloy powder. Background Technology

[0002] Alloy powder is a metal powder formed by the partial or complete alloying of two or more components. Alloy powders are mainly classified by composition into iron alloy powder, copper alloy powder, nickel alloy powder, cobalt alloy powder, aluminum alloy powder, titanium alloy powder, and precious metal alloy powder, etc.

[0003] The production of alloy powder requires multiple screening processes to separate alloy powders of different particle sizes, which can then be classified or subjected to secondary crushing. Existing alloy powder screening devices generally use plate screening, which uses vibration to increase the falling rate of the powder. However, this method is inefficient and cannot process a large number of powders at the same time. Therefore, we propose a screening device for powdered alloy powder with high screening efficiency. Utility Model Content

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A screening device for powdered alloy powder includes: a body assembly and a screening component disposed on the body assembly; the screening component includes a screening mechanism installed in the body assembly, a limiting mechanism disposed in the screening mechanism, and a feeding mechanism disposed at the end of the body assembly; the screening mechanism includes a motor installed at the end of the body assembly, a screening chamber fixed to the drive end of the motor, a screen disposed in the middle of the screening chamber, and an inlet and an outlet opened at both ends of the screening chamber; the limiting mechanism includes a movable frame installed in the middle of the body assembly, a movable machine assembled in the movable frame, an air inlet pipe fixed on the movable machine, an air pump connected to the air inlet pipe, a limiting plate sleeved on the end of the air inlet pipe, a diversion cavity opened in the limiting plate, a sealing ring connected to the side of the limiting plate, and an annular airbag connected to the sealing ring.

[0007] In a preferred embodiment, the present invention can be further configured such that the body component includes a screening tank and a discharge port opened at the bottom of the screening tank.

[0008] In a preferred embodiment, the present invention can be further configured such that the feeding mechanism includes a spring fixed within the body assembly, a mounting bracket fixed to the end of the spring, and a feeding hopper mounted in the middle of the mounting bracket and located on the feed inlet side.

[0009] In a preferred embodiment, the present invention can be further configured such that the feeding hopper has a conical shape.

[0010] In a preferred embodiment, the present invention can be further configured such that the aperture value of the screen gradually increases from the motor side to the moving machine side.

[0013] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] This invention utilizes a screening assembly. A moving machine drives a limiting plate at the end of the air inlet pipe to move, and then an air pump guides the airflow through the air inlet pipe and the diversion chamber into an annular airbag. The annular airbag is then fitted and supported against the inner side of the screen. A motor drives the screening chamber to rotate, which in turn drives the limiting plate to rotate synchronously. This causes the alloy powder inside the screen to be discharged from the screen at the corresponding position during rotation. After all the small particles have been discharged, the limiting plate is moved backward. While moving backward, the air pump continues to inflate the airbag, causing the annular airbag to move against the inner wall of the screen. This multi-stage screening of alloy powder is achieved and has high practicality. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of a powdered alloy powder screening device provided by this utility model.

[0024] Combination Figure 1-2 As shown, the present invention provides a screening device for powdered alloy powder, comprising: a body assembly 100 and a screening component 200 disposed on the body assembly 100, wherein the body assembly 100 includes a screening tank 110 and a discharge port 120 opened at the bottom of the screening tank 110.

[0025] The screening component 200 includes a screening mechanism installed within the body component 100, a limiting mechanism disposed within the screening mechanism, and a feeding mechanism disposed at the end of the body component 100. The screening mechanism includes a motor 210 installed at the end of the body component 100, a screening chamber 220 fixed to the drive end of the motor 210, a screen 230 disposed in the middle of the screening chamber 220, and an inlet 240 and an outlet 250 opened at both ends of the screening chamber 220. The limiting mechanism includes a movable frame 310 installed in the middle of the body component 100, a movable machine 320 assembled within the movable frame 310, an air inlet pipe 330 fixed on the movable machine 320, an air pump 340 connected to the air inlet pipe 330, a limiting plate 350 sleeved at the end of the air inlet pipe 330, and a feeding mechanism disposed within the limiting plate 350. The flow divider 360, the sealing ring 370 connected to the side of the limiting plate 350, and the annular airbag 380 connected to the sealing ring 370 are connected to the screening assembly 200. The limiting plate 350 at the end of the air inlet pipe 330 can be moved by the moving machine 320. Then, the air pump 340 guides the airflow through the air inlet pipe 330 and the flow divider 360 into the annular airbag 380, so that the annular airbag 380 fits and supports the inner side of the screen 230. Then, the motor 210 drives the screening chamber 220 to rotate, and drives the limiting plate 350 to rotate synchronously. The alloy powder inside the screen 230 is discharged from the screen 230 at the corresponding position while rotating. After the small particles are completely discharged, the limiting plate 350 is moved backward. While moving backward, the air pump 340 keeps inflating, so that the annular airbag 380 moves in contact with the inner wall of the screen 230. In this way, multi-stage screening of alloy powder is achieved, which is highly practical.

[0026] Specifically, the feeding mechanism includes a spring 260 fixed inside the body assembly 100, a mounting bracket 270 fixed to the end of the spring 260, and a feeding hopper 280 installed in the middle of the mounting bracket 270 and located on the side of the feed inlet 240. During feeding, the feeding hopper 280 is pushed inward so that the bottom end of the feeding hopper 280 enters the feed inlet 240, and then the material to be screened is fed into the feeding hopper 280 and slides into the screening chamber 220.

[0027] Furthermore, the motor 210 has a conical structure, which allows materials to slide downwards naturally under rotation, facilitating step-by-step screening.

[0028] On the other hand, the aperture value of the screen 230 gradually increases from the motor 210 side to the moving machine 320 side, which can make the material move backward step by step and discharge the compliant alloy powder on the screen 230 at the corresponding position, which is more reasonable.

[0029] Furthermore, the sealing rings 370 are equidistantly distributed on the annular airbag 380. The sealing rings 370 can be used to seal the position of the limiting plate 350 after adjustment, preventing material from leaking backward. The position of the sealing rings 370 after unfolding is the dividing line of the change in the aperture value on the screen 230.

[0030] Furthermore, the limiting plate 350 is fixed with an adapter sleeve 351 connected to the air inlet pipe 330 in the middle, which allows the limiting plate 350 to rotate with the screening chamber 220 without affecting the air supply of the air inlet pipe 330, while the air inlet pipe 330 provides support for the screening chamber 220.

[0031] The working principle and usage process of this utility model are as follows: First, the moving machine 320 drives the limiting plate 350 at the end of the air inlet pipe 330 to move. Then, in conjunction with the air pump 340, the airflow is introduced into the annular airbag 380 through the air inlet pipe 330 and the diversion chamber 360, so that the annular airbag 380 fits and supports the inner side of the screen 230. Then, the feeding hopper 280 is pushed inward so that the bottom end of the feeding hopper 280 enters the feed inlet 240. Then, the material to be screened is fed into the feeding hopper 280. The powder slides into the screening chamber 220, and then the motor 210 drives the screening chamber 220 to rotate, which in turn drives the limiting plate 350 to rotate synchronously. This causes the alloy powder inside the screen 230 to be discharged from the screen 230 at the corresponding position while rotating. After the small particles are completely discharged, the limiting plate 350 is moved backward. While moving backward, the air pump 340 keeps inflating, which causes the annular airbag 380 to move against the inner wall of the screen 230. This achieves multi-stage screening of alloy powder.

[0032] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
