Technical Field
[0001] The utility model relates to the technical field of metal alloy powder filtration, and more specifically, to a filtration device for improving the purity of metal alloy powder. Background Technique
[0002] Metal powder refers to a group of metal particles with a size less than 1 mm, including single metal powder, alloy powder, and some refractory compound powders with metallic properties. It is the main raw material for powder metallurgy. During the use of high-metal alloy powder, in order to improve its purity, it is necessary to screen and filter it to remove some impurities inside. At this time, a filtration device, namely a vibrating screen, is needed.
[0003] When the existing filtration device is in use, the metal alloy powder is usually directly added to the inside for vibrating screening, so as to screen and filter it to improve its purity. However, if the metal alloy powder is relatively wet, directly screening and purifying it, the damp part is very likely to be incompletely screened, thus affecting the screening and purifying effect of the metal alloy powder. In view of this, we propose a filtration device for improving the purity of metal alloy powder. Content of the Utility Model
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a filtration device for improving the purity of metal alloy powder, so as to solve the technical problem that the current filtration device has a poor screening and purifying effect on damp metal alloy powder.
[0005] To solve the above technical problems, the utility model provides the following technical solution: A filtration device for improving the purity of metal alloy powder, including a bracket, a vibrating screen is arranged inside the bracket, a box body is arranged on the top of the bracket, a storage bucket is arranged on one side of the top of the box body through a mounting rod, a discharge pipe is arranged at the bottom of the storage bucket, the discharge pipe is communicated with the inside of the box body, a hot air blower is arranged on the top of the box body, an air inlet pipe is arranged on the surface of the discharge pipe, and the output end of the hot air blower is connected to the air inlet pipe through a conduit. An outlet is arranged in the center of the bottom of the box body, and the outlet is connected with a flexible pipe, and the flexible pipe is connected to the input end of the top of the vibrating screen;
[0006] A guiding plate is arranged inside the box body, and the guiding plate is arranged in a horizontal spiral form.
[0007] The utility model designs structures such as a box body, a storage barrel, and a hot air blower. Therefore, when screening and purifying metal alloy powder, the metal alloy powder can be directly added to the storage barrel, and then the metal alloy powder will fall into the interior of the box body through the discharge pipe. At the same time, the hot air blower is controlled to work, and hot air enters the discharge pipe and enters the box body together with the metal alloy powder. During this process, the drying operation of the metal alloy powder can be realized, thereby ensuring the dryness of the metal. The dry metal alloy powder enters the vibrating screen through a hose for vibrating screening and purification, so as to ensure the screening and purification effect of the metal alloy powder. After the hot air enters the box body, under the action of the spiral guide plate, the hot air will move in a spiral motion from the outside to the inside until it reaches the center of the box body. During this process, the hot air will drive the metal alloy powder to move in a spiral motion synchronously, and then be discharged from the center of the box body, which can greatly increase the contact time between the hot air and the metal alloy powder, ensure the drying effect of the metal alloy powder, and during the spiral motion of the metal alloy powder in the box body, it will also be in full contact with the hot air, further improving the drying effect of the hot air on the metal alloy powder, and ensuring the dryness of the metal alloy powder entering the vibrating screen, avoiding the phenomenon of incomplete drying, and at the same time being able to ensure that the dried metal alloy powder quickly enters the vibrating screen.
[0008] Preferably, the bracket includes a bottom plate, the vibrating screen is symmetrically arranged on the bottom plate, support rods are equidistantly arranged around the top of the bottom plate, and a top plate is arranged at the top of the support rods. The box body is symmetrically arranged on the top plate.
[0009] Preferably, a through hole is opened at the center of the top plate, and the diameter of the through hole is larger than the diameter of the discharge port.
[0010] Preferably, the box body includes an open box, a box cover is arranged on the top of the open box, several groups of first welding blocks are equidistantly arranged around the open box, and mounting bolts connected to the first welding blocks are arranged around the top of the box cover.

[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] 1. The utility model designs structures such as a box body, a storage barrel, and a hot air blower. Therefore, when screening and purifying metal alloy powder, the metal alloy powder can be directly added to the storage barrel, and then the metal alloy powder will fall into the interior of the box body through the discharge pipe. At the same time, the hot air blower is controlled to operate, and hot air enters the discharge pipe and enters the box body together with the metal alloy powder. During this process, the drying operation of the metal alloy powder can be achieved, thereby ensuring the dryness of the metal. The dry metal alloy powder enters the vibrating screen through a hose for vibrating screening and purification, so as to ensure the screening and purification effect of the metal alloy powder, and solve the technical problem that the current filtering device has a poor screening and purification effect on damp metal alloy powder. Therefore, the utility model has the advantage of drying metal alloy powder.
[0015] 2. The utility model also arranges a guide plate inside the box body. The guide plate is arranged in the box body in a horizontal spiral form. Therefore, after the hot air enters the interior of the box body, under the action of the spiral guide plate, the hot air will move in a spiral motion from the outside to the inside until it reaches the center of the box body. During this process, the hot air will drive the metal alloy powder to move synchronously in a spiral motion and then be discharged from the center of the box body. Thus, the contact time between the hot air and the metal alloy powder can be greatly increased, and the drying effect of the metal alloy powder can be ensured. Moreover, during the spiral movement of the metal alloy powder in the box body, it will also be in full contact with the hot air, further improving the drying effect of the hot air on the metal alloy powder, ensuring the dryness of the metal alloy powder entering the vibrating screen, avoiding incomplete drying, and at the same time ensuring that the dried metal alloy powder can quickly enter the vibrating screen.

[0023] As Figures 1 to 5 shown, a filtering device for improving the purity of metal alloy powder according to the present utility model includes a support 1. A vibrating screen 2 is arranged inside the support 1, and a box body 3 is arranged on the top of the support 1. A storage bucket 5 is arranged on one side of the top of the box body 3 through an installation rod 4. A discharge pipe 501 is arranged at the bottom of the storage bucket 5, and the discharge pipe 501 is communicated with the inside of the box body 3. A hot air blower 6 is arranged on the top of the box body 3. An air inlet pipe 502 is arranged on the surface of the discharge pipe 501. The output end of the hot air blower 6 is connected to the air inlet pipe 502 through a conduit. A discharge port 303 is arranged at the center of the bottom of the box body 3, and the discharge port 303 is connected with a hose 304. The hose 304 is connected to the input end of the top of the vibrating screen 2. When screening and purifying the metal alloy powder, the metal alloy powder can be directly added into the storage bucket 5, and then the metal alloy powder will fall into the inside of the box body 3 through the discharge pipe 501. At the same time, control the hot air blower 6 to work, and the hot air enters the discharge pipe 501 and enters the box body 3 together with the metal alloy powder, and then enters the vibrating screen 2 through the hose 304. During this process, the hot air can realize the drying operation of the metal alloy powder, so as to ensure the dryness of the metal alloy powder. The dry metal alloy powder enters the inside of the vibrating screen 2 through the hose 304 for vibration screening and purification, so as to ensure the screening and purification effect of the metal alloy powder.
[0024] Specifically, the support 1 includes a bottom plate 101. The vibrating screen 2 is arranged on the bottom plate 101 in a centrosymmetric manner. A support rod 102 is arranged equidistantly around the top of the bottom plate 101, and a top plate 103 is arranged at the top of the support rod 102. The box body 3 is arranged on the top plate 103 in a centrosymmetric manner. The top plate 103 facilitates the installation of the box body 3, separates the box body 3 from the vibrating screen 2, and avoids the influence of the vibration of the vibrating screen 2 on the box body 3.
[0025] Furthermore, a through hole 104 is opened at the center of the top plate 103, and the diameter of the through hole 104 is larger than the diameter of the discharge port 303. The through hole 104 facilitates the passage of the discharge port 303.
[0026] Furthermore, the box body 3 includes an open box 301. A box cover 302 is arranged on the top of the open box 301. A number of groups of first welding blocks 305 are arranged equidistantly around the open box 301. Mounting bolts 306 connected to the first welding blocks 305 are arranged around the top of the box cover 302. By unscrewing the mounting bolts 306, the box cover 302 can be opened, facilitating regular cleaning of the open box 301 by personnel.
[0027] It is worth noting that a bucket cover 503 is hingedly arranged on the top of the storage bucket 5. A third welding block 505 is arranged on one side of the bucket cover 503. A second welding block 504 symmetrical to the third welding block 505 is arranged on one side of the storage bucket 5. A fixing bolt 506 connected to the second welding block 504 is arranged on the third welding block 505. After the metal alloy powder is added into the storage bucket 5, the bucket cover 503 can be covered, and then the fixing bolt 506 on the third welding block 505 can be screwed into the second welding block 504, thereby fixing the bucket cover 503, that is, realizing the sealing of the top opening of the storage bucket 5.
[0028] It is worth introducing that the air inlet pipe 502 is arranged obliquely, and the port of the air inlet pipe 502 faces in a certain direction. The hot air will enter the inside of the discharge pipe 501 in an obliquely downward blowing direction through the inclined air inlet pipe 502. Thus, the hot air can smoothly enter the box body 3 from the discharge pipe 501, avoiding the phenomenon of hot air blowing upward, and being able to drive the metal alloy powder to smoothly enter the box body 3.
[0029] In the embodiment of the present utility model, a guide plate 7 is arranged inside the box body 3. The guide plate 7 is arranged in a horizontal spiral form. After the hot air enters the box body 3, under the action of the spiral guide plate 7, the hot air will perform a spiral movement from the outside to the inside in the box body 3 until it reaches the center of the box body 3. During this process, the hot air will drive the metal alloy powder to perform a synchronous spiral movement and then discharge from the center of the box body 3. Thereby, the contact time between the hot air and the metal alloy powder can be greatly increased, ensuring the drying effect of the hot air on the metal alloy powder. And during the spiral movement of the metal alloy powder in the box body 3, it will also be in full contact with the hot air, further improving the drying effect of the hot air on the metal alloy powder, ensuring the dryness of the metal alloy powder entering the vibrating screen 2, avoiding the phenomenon of incomplete drying, and at the same time being able to ensure that the dried metal alloy powder quickly enters the vibrating screen 2.
[0030] Working principle: This embodiment provides a filtering device for improving the purity of metal alloy powder. First, when screening and purifying the metal alloy powder, the metal alloy powder can be directly added to the storage bucket 5, and then the metal alloy powder will fall into the interior of the box body 3 through the discharge pipe 501. At the same time, control the hot air blower 6 to work, and the hot air enters the discharge pipe 501 and enters the box body 3 together with the metal alloy powder, and then enters the vibrating screen 2 through the hose 304. During this process, the hot air can perform the drying operation on the metal alloy powder, thereby ensuring the dryness of the metal alloy powder. The dry metal alloy powder enters the interior of the vibrating screen 2 through the hose 304 for vibrating screening and purification, so as to ensure the screening and purification effect of the metal alloy powder;
[0031] Secondly, the hot air enters the interior of the discharge pipe 501 in an inclined downward blowing direction through the inclined air inlet pipe 502, so that the hot air can smoothly enter the box body 3 from the discharge pipe 501, avoiding the phenomenon of hot air blowing upward, and being able to drive the metal alloy powder to smoothly enter the box body 3;
[0032] Finally, after the hot air enters the box body 3, under the action of the spiral guide plate 7, the hot air will perform a spiral movement from the outside to the inside in the box body 3 until it reaches the center of the box body 3. During this process, the hot air will drive the metal alloy powder to perform a synchronous spiral movement and then be discharged from the center of the box body 3. Thereby, the contact time between the hot air and the metal alloy powder can be greatly increased, ensuring the drying effect of the hot air on the metal alloy powder. And during the spiral movement of the metal alloy powder in the box body 3, it will also be in full contact with the hot air, further improving the drying effect of the hot air on the metal alloy powder, ensuring the dryness of the metal alloy powder entering the vibrating screen 2, avoiding the phenomenon of incomplete drying, and at the same time being able to ensure that the dried metal alloy powder quickly enters the vibrating screen 2.

Those of ordinary skill in the art can easily understand the spirit of this utility model based on the above embodiments and make different extensions and changes, but as long as they do not depart from the spirit of this utility model, they are within the protection scope of this utility model.
