Description

Technical Field

[0001] This utility model relates to the technical field of alloy powder screening equipment, specifically a copper-clad iron alloy powder screening device. Background Technology

[0002] Previously, when screening alloys, after the material was poured in through the feed inlet, it would accumulate on the screen, requiring an additional power mechanism to vibrate it to disperse the material, which greatly affected the screening process. Moreover, because the connection between the cylinders was not very tight, some material would leak out.

[0003] Document CN 219092709 U discloses an alloy powder sieving device, including a base, a sieving shell, and an elastic element. The sieving shell is positioned above the base, and the elastic element is fixedly connected to both the base and the sieving shell. A vibrator is installed at the bottom of the sieving shell. Several screen frames are detachably connected to the sieving shell, and these screen frames can be stacked on top of each other and secured with fastening components. Filter screens are detachably connected to the screen frames. Two sliders are slidably connected to the side walls of the filter screens, with the sliding direction of the sliders perpendicular to the installation direction of the filter screens. Compression springs are provided for the sliders and filter screen supports to allow the sliders to be housed within the filter screens. Limiting grooves adapted to the sliders are formed on the side walls of the screen frames, allowing the sliders to engage with the limiting grooves to secure the filter screens. A reset rod is slidably connected to the inner wall of the screen frame, with one end of the reset rod protruding from the screen frame. Although this structure can seal the cylinders, the locking force of the snap-fit ​​is weak, resulting in low sealing strength between the cylinders and making it easy for internal materials to leak.

[0004] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0005] To address the aforementioned problems, this utility model discloses a copper-clad iron alloy powder screening device. This device improves the overall sealing performance of the device and allows the alloy powder to be evenly distributed on the screen without any driving equipment to vibrate it. This ensures that the screen can fully screen the alloy, preventing material accumulation and low screening efficiency. Furthermore, the strong sealing performance prevents material from leaking out, thus improving screening efficiency.

[0006] The technical solution of this utility model is as follows: a copper-clad iron alloy powder screening device, including a screening cylinder, a feed inlet and a discharge outlet. The upper and lower parts of the screening cylinder are respectively equipped with screens. The feed inlet and the discharge outlet are located at the top and bottom of the screening cylinder, respectively. A feed distribution plate is provided below the feed inlet. The diameter of the feed distribution plate is larger than the diameter of the feed inlet. The screening cylinders are fixedly connected by buckles. The buckles are generally in an outward arc shape.

[0007] By adopting the above technical solution, the alloy powder enters the screening cylinder from the feed inlet. After passing through the feed distribution plate, the alloy powder is impacted by the shape of the distribution plate and then ejected to the upper side wall of the screening cylinder, and then falls onto the upper screen for screening. This facilitates the uniform distribution of the alloy powder. The screening cylinder is tightly fixed together by snap fasteners.

[0008] Preferably, the feed distribution disc is connected to the inner wall of the screening cylinder around the feed inlet by a bracket, and the feed distribution disc includes an impact part and a receiving part.

[0009] By adopting the above technical solution, when the alloy powder enters from the feed port and falls downwards, it hits the impact part and is ejected by the impact part.

[0010] Preferably, the impact part is a cone with the tip pointing upwards, the angle of the cone is no more than 45 degrees, the receiving part at the bottom of the impact part is hemispherical, the center of the cone of the receiving part and the center of the feed inlet are on a straight line, and the diameter of the bottom of the impact part and the hemispherical part of the receiving part are both larger than the feed inlet.

[0011] By adopting the above technical solution, after the alloy powder is ejected by the side wall of the screening cylinder, it impacts the receiving part at the bottom of the impact part again, and then is bounced to the bottom screen, so that the alloy powder can be evenly distributed on the screen.

[0012] Preferably, the bottom of the support is located on top of the feed distribution plate, in a V-shape, and the top is welded to the inner wall of the screening cylinder around the feed inlet.

[0013] By adopting the above technical solution, the bracket is used to support the feed distribution disc on the side wall of the screening cylinder.

[0014] Preferably, the bottom of the buckle is connected to the lower part of the adjacent screening cylinder, the buckle is connected to the connecting ear of the lower screening cylinder, and the upper part of the buckle is flipped upward.

[0015] By adopting the above technical solution, the screen cylinder below is connected by a buckle. The buckle flips upward around the side connection of the screen cylinder, which can squeeze the screen cylinder above, making the connection between the two adjacent screen cylinders tighter.

[0016] Preferably, the connecting lugs between the screening cylinders are all inside the arc of the buckle, and the end of the buckle is provided with a fixing lug plate for fixing. The fixing lug plate is fixed to the uppermost one of the adjacent screening cylinders by bolts.

[0017] By adopting the above technical solution, the upper and lower screening cylinders can be tightly connected by using buckles to flip them over and by using bolts to squeeze them.

[0018] Preferably, the screen has an upper screen and a lower screen, with the diameter of the upper screen being larger than the screening diameter of the lower screen.

[0019] By adopting the above technical solution, alloy powders of different diameters can be finely sieved.

[0020] The advantages of this utility model are as follows: 1. By setting a feeding distribution plate below the feed inlet of the screening cylinder, the alloy powder can be ejected and splashed by the feeding distribution plate when the alloy powder is poured in, which can improve the uniformity of the alloy powder distribution.

[0021] 2. This utility model provides an arc-shaped buckle at the connecting lug on the side of the screening cylinder. When the buckle is flipped upward, the upper screening cylinder can be pressed downward, thereby improving the tightness of the connection between the screening cylinders.

[0022] 3. This utility model improves the overall sealing of the device and also allows the alloy powder to be evenly distributed on the upper screen, thereby improving the screening efficiency. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] like Figure 1-4As shown, the copper-clad iron alloy powder screening device includes a screening cylinder 1, an inlet 2, and an outlet 3. The upper and lower parts of the screening cylinder 1 are respectively equipped with screens. The inlet 2 and the outlet 3 are located at the top and bottom of the screening cylinder 1, respectively. A feed distribution plate 4 is provided below the inlet 2. The diameter of the feed distribution plate 4 is larger than the diameter of the inlet. The screening cylinders 1 are fixedly connected by a buckle 5. The buckle 5 is generally arc-shaped outward. The alloy powder enters the screening cylinder 1 from the inlet 2. After passing through the feed distribution plate 4, the alloy powder is impacted by the shape of the distribution plate and then ejected to the upper side wall of the screening cylinder 1, and then falls onto the upper screen 6 for screening. This facilitates the uniform distribution of the alloy powder. The screening cylinders 1 are tightly fixed together by the buckle 5.

[0030] The feed distribution plate 4 is connected to the inner wall of the screening cylinder 1 around the feed inlet 2 via a bracket 403. The feed distribution plate 4 includes an impact part 401 and a receiving part 402. When the alloy powder enters from the feed inlet 2 and falls downward, it hits the impact part 401 and is ejected by the impact part 401.

[0031] The impact section 401 is a cone with the tip pointing upwards, and the angle of the cone is no more than 45 degrees. The receiving section 402 at the bottom of the impact section 401 is hemispherical. The center of the cone of the receiving section 402 and the center of the feed inlet are on a straight line. The diameter of the bottom of the impact section 401 and the hemispherical shape of the receiving section 402 are both larger than the feed inlet 2. After the alloy powder is ejected by the side wall of the screening cylinder, it impacts the receiving section at the bottom of the impact section again, and then is bounced to the bottom screen, so that the alloy powder can be evenly distributed on the screen.

[0032] The bottom of the bracket 403 is located on top of the feed distribution plate 4 and is V-shaped. The top is welded to the inner wall of the screening cylinder 1 around the feed inlet. The bracket 403 is used to support the feed distribution plate 4 on the side wall of the screening cylinder 1.

[0033] The bottom of the buckle 5 is connected to the lower part of the adjacent screening cylinder 1. The buckle 5 is connected to the connecting ear of the lower screening cylinder 1. The upper part of the buckle 5 is flipped upward and connected to the lower screening cylinder 1 through the buckle 5. The buckle 5 is flipped upward around the side connection of the screening cylinder 1, which can squeeze the upper screening cylinder 1, making the connection between the two adjacent screening cylinders 1 tighter.

[0034] The connecting ears 101 between the screening cylinders 1 are all inside the arc of the buckle 5. A sealing ring 102 can also be provided between the connecting ears 101. The end of the buckle 5 is provided with a fixing ear plate 501 for fixing. The buckle 5 on the connecting ear 101 is set at a 60-degree angle with the feed port 2 as the center. The fixing ear plate 501 is fixed to the upper one of the adjacent screening cylinders 1 by bolts. By flipping the buckle 5 inward and pressing it with bolts, the upper and lower screening cylinders 1 can be tightly connected.

[0035] The screen is equipped with an upper screen 6 and a lower screen 7. The diameter of the upper screen 6 is larger than the screening diameter of the lower screen 7, which can finely screen alloy powders of different diameters.

[0036] Alloy powder is introduced into the screening cylinder 1 through the feed inlet 2. Then, the alloy powder is ejected to the side of the screening cylinder by the feed distribution plate 4 and falls onto the upper screen 6. Some of it is ejected onto the screen by the receiving part 402, which effectively improves the uniformity of the alloy powder distribution on the screen and avoids the accumulation of alloy powder in a certain position. The buckle can tightly fix the connecting lug 101 of the screening cylinder 1, improving the sealing degree of the connection between the screening cylinders 1.
