Description

Technical Field

[0001] This utility model relates to the field of metal powder recycling technology, specifically a metal powder ejection device. Background Technology

[0002] Metal dust waste generated during the processing of metal composite materials and friction materials (flat grinding, sawing, chamfering, grinding outer arc, grinding inner arc, etc.) is directly treated as garbage without effective separation, recycling, or reuse. Moreover, the metal dust contains a large amount of precious metals such as copper, brass, and steel fibers. Directly treating it as garbage wastes a lot of resources and causes varying degrees of environmental pollution.

[0003] A prior art patent document with publication number CN 110877012 A discloses a powdered metal recycling device. This device uses a filter screen to separate qualified micro-metal particles. These particles fall through the filter screen and accumulate on a collection plate. When a certain amount of metal waste accumulates on the collection plate, pulling the lever to the right pulls the plate out of the housing, thus collecting and recycling the waste. This invention has a simple structure and solves the problem of wasting resources by treating powdered metal as garbage, demonstrating the advantage of effectively recycling powdered metal.

[0004] However, the above technical solution has certain shortcomings. Since the top of the filter screen is horizontal, as the amount of falling metal waste increases, the metal waste particles on the top will also gradually increase, eventually covering the filter and preventing the subsequent metal waste from being screened, resulting in a slow progress in the recycling and processing of metal powder. Therefore, a metal powder ejection device is proposed. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a metal powder ejection device to solve the technical problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a metal powder ejection device, comprising an outer frame, wherein a sieving component for sieving metal powder is assembled inside the outer frame, a feed pipe is provided at the top of the outer frame, a dust outlet is assembled on one side of the outer frame, and a fan for removing dust from the metal powder is assembled on the other side of the outer frame.

[0007] The screening assembly includes a frame that slides inside the outer frame. A filter screen is fitted on the inner wall of the frame. The middle of the frame and the filter screen is convex. Two sets of staggered baffles are fitted on the inclined surface of the filter screen. The bottom of each set of baffles is fixed to the inclined surface of the frame. A driven shaft that rotates on the inner wall of the outer frame is provided laterally at the bottom of the frame. An elliptical disk that contacts the bottom of the frame is fixedly sleeved on the outer wall of the driven shaft. Drop openings are provided on both the front and rear surfaces of the frame. A collection drawer is fitted inside the outer frame below the frame.

[0008] As a preferred technical solution, the fan blade shaft and the driven shaft of the fan are fitted with a belt for transmission, and a pulley is provided at the contact position between the belt and the driven shaft and the fan blade shaft.

[0009] As a preferred technical solution, each end of the frame is provided with two sets of sliders extending into the outer frame, and the inner wall of the outer frame is provided with a stroke groove at the contact position with the slider, and the bottom of the slider is fixed with a spring to the inner wall of the stroke groove.

[0010] As a preferred technical solution, one side of the outer frame is provided with an inlet / outlet for the collection drawer to slide out, and the top of the collection drawer is fixed with a frame below each set of drop openings.

[0011] As a preferred technical solution, the end of the dust outlet away from the outer frame is open, and a mesh is installed at the open position.

[0012] As a preferred technical solution, the end face cross-sections of the frame and the filter screen are triangular, and the baffle plate mounted on the inclined surface of the filter screen is in an inclined state.

[0013] In summary, the present invention has the following main advantages:

[0014] This invention uses a screening component to allow the metal waste to flow along a longer trajectory at the top of the filter screen, achieving a thorough screening effect for metal waste of varying sizes. At the same time, it causes large metal particles to tend to slide to one side, preventing them from clogging the filter screen and affecting the screening purpose. This can indirectly improve the overall processing speed of metal powder. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] A metal powder ejection device, such as Figures 1 to 5 As shown, it includes an outer frame 100, a screening assembly 200 for screening metal powder is installed inside the outer frame 100, a feed pipe 110 is provided on the top of the outer frame 100, a dust outlet 120 is installed on one side of the outer frame 100, and a fan 130 for removing dust from the metal powder is installed on the other side of the outer frame 100.

[0026] The screening assembly 200 includes a frame 210 slidably disposed inside the outer frame 100. A filter screen 220 is fitted on the inner wall of the frame 210. The middle part of the frame 210 and the filter screen 220 is raised. Two sets of staggered baffles 230 are fitted on the inclined surface of the filter screen 220. The bottom of each set of baffles 230 is fixed to the inclined surface of the frame 210. A driven shaft 260 rotating on the inner wall of the outer frame 100 is provided laterally at the bottom of the frame 210. An elliptical disk 250 that contacts the bottom of the frame 210 is fixedly sleeved on the outer wall of the driven shaft 260. A drop opening 240 is opened on the front and rear surfaces of the frame 210. A collection drawer 140 is fitted inside the outer frame 100 below the frame 210.

[0027] The fan blade shaft inside the fan 130 is fitted with a belt for transmission on the outer wall of the driven shaft 260, and a pulley is provided at the contact position between the belt and the driven shaft 260 and the fan blade shaft.

[0028] Metal powder enters the outer frame 100 through the feed pipe 110, and the blower 130 blows the incoming metal powder. Since the metal particles are heavier than the dust, the dust is blown by the blower 130 towards the dust outlet 120 and discharged to the outside, while the metal particles fall onto the top of the filter screen 220. Small particles fall through the filter screen 220 into the collection tray 140 below, while large metal waste particles flow back along the two sets of baffles 230 at the top of the filter screen 220. The movement of the fan 130 allows it to be more thoroughly screened by the filter screen 220. At the same time, when the fan 130 is working, it will drive the driven shaft 260 to rotate synchronously via the belt. The elliptical disc 250 on its outer wall will continuously vibrate the frame 210 and the internal filter screen 220, causing large metal waste particles to fall out of the filter screen mesh, thus avoiding clogging of the filter screen 220. Finally, the large metal waste particles will enter the frame 141 through the drop outlet 240 and can be removed synchronously with the collection tray 140.

[0029] Please refer to this carefully. Figure 4 and Figure 5 Two sets of sliders 211 extending into the outer frame 100 are provided at both ends of the frame 210. A stroke groove 102 is reserved at the contact position between the inner wall of the outer frame 100 and the slider 211. A spring 212 is fixed to the bottom of the slider 211 and the inner wall of the stroke groove 102.

[0030] The slider can move upward along the travel groove 102 to stretch the spring 212, and the elasticity of the spring 212 allows it to return to its original state, thus causing the filter screen 220 to vibrate.

[0031] Please refer to this carefully. Figure 3 The outer frame 100 has an inlet / outlet notch 101 on one side for the collection drawer 140 to slide out, and the top of the collection drawer 140 is fixed with a frame 141 below each set of drop openings 240.

[0032] Large metal particles that remain at the top of the filter screen 220 are allowed to enter the frame 141 through the drop outlet 240. When external force is applied to the collection tray 140, the frame 141 and the collection tray can be removed through the inlet / outlet notch 101, thereby removing the screened metal powder.

[0033] Please refer to this carefully. Figure 1 and Figure 2 The dust outlet 120 is open at the end away from the outer frame 100, and a mesh is installed at the open position.

[0034] This allows the dust blown by the fan 130 to be discharged from the dust outlet 120, while the mesh protects it from external objects entering, thus ensuring that the top of the internal screening component 200 is kept clean.

[0035] Please refer to the figure carefully. The end face cross-sections of the frame 210 and the filter screen 220 are triangular, and the spoiler 230 mounted on the beveled surface of the filter screen 220 is in an inclined state.

[0036] It serves to guide the incoming metal powder, allowing it to slide along a longer path on the top of the filter screen 220, thus fully separating metal waste particles of different sizes.

[0037] In use, metal powder enters the outer frame 100 through the feed pipe 110, and the blower 130 blows the incoming metal powder. Since the metal particles are heavier than the dust, the dust is blown by the blower 130 towards the dust outlet 120 and discharged to the outside, while the metal particles fall onto the top of the filter screen 220. Small particles pass through the filter screen 220 and fall into the collection tray 140 below, while large metal waste particles flow back and forth along the two sets of baffles 230 at the top of the filter screen 220, so that they are sieved by the filter screen 220. The separation is more thorough. At the same time, when the fan 130 is working, it will drive the driven shaft 260 to rotate synchronously via the belt. The elliptical disk 250 on its outer wall will continuously vibrate the frame 210 and the internal filter screen 220, causing large metal waste particles to fall out of the filter screen mesh, thus avoiding clogging of the filter screen 220. Finally, the large metal waste particles will enter the frame 141 through the drop outlet 240 and can be taken out synchronously with the collection tray 140. The parts of this device not mentioned are the same as or can be implemented using existing technology.
