Description
Technical Field
[0001] This utility model relates to the technical field of gravity separation equipment, specifically a gravity separation equipment for copper powder and resin powder. Background Technology
[0002] After waste circuit boards are crushed, a mixture of copper powder and resin powder is formed, which needs to be separated. This is achieved using a gravity separator to separate particles with significantly different specific gravities from the mixture, removing excessively large and small particles. Currently, wind-powered gravity separators are commonly used for this separation. These separators utilize wind power to blow out lighter particles, thus separating materials with different specific gravities. However, some existing wind-powered separators, due to wind direction and force, cannot blow lighter particles to the discharge port, instead sending them along with heavier particles into another discharge port, thus affecting the separation effect. To address these issues, the inventors have proposed a copper powder and resin powder gravity separator to solve these problems. Utility Model Content
[0003] To address the problem that some existing wind-powered separators fail to blow lighter particles to the discharge port due to wind direction and force, instead sending them along with heavier particles into another discharge port, thus affecting the separation effect, the purpose of this invention is to provide a gravity separation device for copper powder and resin powder.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a copper powder and resin powder specific gravity separation device, including a box body, a feed inlet at the top of the box body, a first discharge outlet and a second discharge outlet distributed vertically on one side of the box body, a third discharge outlet on the side of the box body away from the first discharge outlet, a sliding frame slidably installed inside the box body, a first sorting screen fixedly installed at the top of the sliding frame, a second sorting screen fixedly installed at the bottom of the sliding frame, and the mesh size of the second sorting screen is smaller than that of the first sorting screen, a guide bucket fixedly installed on the lower surface of the first sorting screen, a discharge outlet at the bottom of the guide bucket, a fan unit fixedly installed on the side of the box body with the third discharge outlet, a crankshaft rotatably installed inside the box body, connecting plates hinged to both sides of the bottom end of the sliding frame, and the connecting plates are hinged to the crankshaft, a drive motor fixedly installed on one side of the box body, and the output end of the drive motor is fixedly connected to one end of the crankshaft.
[0005] Preferably, two mirror-distributed sliding strips are fixedly installed on both sides of the sliding frame, and two symmetrically distributed guide grooves are opened on both sides of the inside of the box. The sliding frame slides up and down along the guide grooves through the sliding strips, and a collection box is slidably installed at the bottom inside the box.
[0006] Preferably, baffles are slidably installed inside the first discharge port, the second discharge port, and the third discharge port, and a limit component is installed at one end of each of the three discharge ports. Each of the three limit components includes a fixing frame, and a limit rod is slidably inserted into each of the three fixing frames.
[0007] Preferably, each of the three limiting rods is fitted with a spring, a pull ring is fixedly installed at one end of each of the three limiting rods, and a limiting hole is opened at one end of each of the three baffles, and one end of the limiting rod can be inserted into the corresponding limiting hole.
[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0009] 1. In this utility model, by setting an inverted V-shaped second sorting screen and setting a guide bucket on the lower surface of the first sorting screen, the material after being screened by the first sorting screen falls into the guide bucket and then falls onto the second sorting screen through the discharge port. The second sorting screen can screen and isolate materials that meet the standards. During the falling process, the blower unit can blow the light particles in the material to the light particle discharge area and fall onto the second sorting screen, so that the light particles are discharged through the second discharge port. The heavy particles can fall directly onto the second sorting screen through the heavy particle discharge area, so that the heavy particles are discharged through the third discharge port. This achieves the separation of light and heavy particles in the material and discharges them separately, effectively improving the separation effect.
[0010] 2. In this utility model, by setting a baffle and a limiting component, the baffle is in a closed state during the screening process, which can prevent the material that has not been completely screened from falling out. After screening is completed, the baffle can be removed so that the screened material can be discharged through the discharge port. The limiting component can be used to limit the baffle.

First, the drive motor 6 drives the crankshaft 15 to rotate rapidly. The crankshaft 15 drives the sliding frame 10 to swing back and forth inside the housing 1 through the connecting plates 16. Then, the material to be sorted is put into the housing 1 from the feed port 2 for sorting. The first sorting screen 12 can isolate and screen out large particles in the material that exceed the standard, and can discharge them through the first discharge port 3. The material after being screened by the first sorting screen 12 The material falls into the guide hopper 17 and then onto the second sorting screen 13 through the discharge port 18. The second sorting screen 13 can screen and isolate materials that meet the standards. During the falling process, the blower unit 11 can blow the light particles in the material to the light particle discharge area and onto the second sorting screen 13, so that the light particles are discharged through the second discharge port 4. The heavy particles can directly fall onto the second sorting screen 13 through the heavy particle discharge area, so that the heavy particles are discharged through the third discharge port 7. This achieves the separation of light and heavy particles in the material and discharges them separately, effectively improving the separation effect.
[0023] Two mirror-distributed slide bars 14 are fixedly installed on both sides of the sliding frame 10. Two symmetrically distributed guide grooves 19 are opened on both sides of the inside of the housing 1, and the sliding frame 10 slides up and down along the guide grooves 19 through the slide bars 14.
[0024] By adopting the above technical solution, the sliding frame 10 drives the first sorting screen 12 and the second sorting screen 13 to slide up and down along the guide groove 19 via the slide bar 14.
[0025] A collection box 9 is slidably installed at the bottom of the inside of the box 1.

[0027] Baffles 5 are slidably installed inside the first discharge port 3, the second discharge port 4, and the third discharge port 7.
[0028] By adopting the above technical solution, the baffle 5 is in the closed state during the screening process, which can prevent the material that has not been completely screened from falling out.

[0031] Springs 803 are fitted on each of the three limit rods 802, and pull rings 804 are fixedly installed on one end of each of the three limit rods 802.
[0032] By adopting the above technical solution, the limiting rod 802 can be moved by pulling the pull ring 804, and the limiting rod 802 can be reset by utilizing the rebound force of the spring 803.
[0033] Each of the three baffles 5 has a limiting hole 501 at one end, and one end of the limiting rod 802 can be inserted into the corresponding limiting hole 501.

[0035] Working Principle: In use, the drive motor 6 first drives the crankshaft 15 to rotate rapidly. The crankshaft 15, through the connecting plate 16, drives the sliding frame 10 to reciprocate up and down within the housing 1. Next, the material to be sorted is placed into the housing 1 through the feed inlet 2 for sorting. The first sorting screen 12 isolates and screens out large particles exceeding the standard. After screening, the baffle 5 is opened, allowing the material to be discharged through the first discharge outlet 3. The material after being screened by the first sorting screen 12 falls into the guide hopper 17 and then through the discharge outlet 18 onto the second sorting screen 13. The second sorting screen 13 isolates and screens out materials that meet the standards. During the descent, the blower unit 11 can blow the light particles in the material to the light particle discharge area and drop them onto the second sorting screen 13. After screening, the baffle 5 is opened to allow the light particles to be discharged through the second discharge port 4. The heavy particles can directly drop onto the second sorting screen 13 through the heavy particle discharge area. After screening, the baffle 5 is opened to allow the heavy particles to be discharged through the third discharge port 7. The non-standard fine particles after being screened by the second sorting screen 13 fall into the collection box 9, thereby separating the light particles (resin powder) and heavy particles (copper powder) in the material and discharging them separately, effectively improving the separation effect.
