[0002] There are many ways to produce copper powder, and each way involves many processes. Among them, screening is an indispensable part of various ways of producing copper powder. However, in the current copper powder screening process, the copper powder is directly scattered on the reference ground after screening. This screening method will produce a large amount of copper dust mist. Long-term and large-scale inhalation of copper smoke can cause metal fume fever. Workers who are exposed to copper dust for a long time often develop contact dermatitis and nasal and eye irritation symptoms, causing sore throat, cough, nasal congestion, rhinitis, etc., and even cause nasal septum perforation. The appearance of copper dust mist in the screening process causes waste of raw materials and affects the health of the operators, indirectly affecting the production efficiency of copper powder.

[0016] Compared with the prior art, the present invention provides a copper powder screening and dust reduction device, which has the following beneficial effects:

[0017] 1. The present invention provides a dustproof bin on the outer cover of the screening bin, and the dustproof bin and the screening bin move synchronously through supporting ribs, so as to follow the screening bin during the screening movement, thereby reducing the diffusion radius of dust and mist after centrifugal movement during the screening process, and forming a closed cabin with the refined screening bin. Through the setting of the transition bin, the diffusion range of dust and mist is further reduced, thereby effectively enhancing the dust reduction effect.

[0018] 2. The present invention performs fine screening through a plurality of sieve holes provided in the filter bin to meet the filtering of diameter particles under the preset standard of copper powder, and performs wrapped screening of the material to be screened by providing a screening and refining bin connected to the dustproof bin, so as to enhance the dust reduction degree of the material to be screened in a closed environment.

[0019] 3. The present invention arranges flipping parts acting on the left and right ends of the screen disc, wherein a clamping head is embedded in the screen disc. The benefit of the present invention is that it can prevent copper powder particles with larger diameters from being filtered and retained on the screen disc after the first stage of operation on the material to be screened, thereby preventing the subsequent operation from causing blockage of the screen holes and even loss of function of the screen disc, thereby effectively enhancing the automatic cleaning degree of the screen disc.

[0020] 4. The present invention realizes the functional drive of the material to be screened by the linkage effect of the polarizing element on the screening bin. On the one hand, the polarizing element realizes the driving of the swinging motion of the screening bin and the screening refinement bin through the linkage effect of the crankshaft and the connecting column. On the other hand, the self-rotation drive of the screening bin and the screening refinement bin is completed through the action of the driving wheel and the synchronous wheel, thereby enhancing the screening effect.

[0021] 5. The present invention arranges a bulk material bin between the coupling component and the screening and refining bin, that is, the bulk material bin is installed at the position where the overall circular motion radius of the equipment is the smallest, and an overflow hole is opened on the annular surface of the bulk material bin to achieve bulking when the bulk material bin rotates. The bulking is carried out through a relatively concentrated position and a constant arc degree, thereby reducing the diffusion radius of the bulking process and thereby reducing the degree of copper dust fog.

[0022] In summary, the present invention enhances the dust reduction effect for copper powder screening by performing a closed transition in the screening process in the screening bin until the material is bulked. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] First, the material enters the screening bin 1 and is left to stand, and the polarizing element 3 is used to continuously screen the screening bin 1 and the screening refinement bin 4, and through a combination of reciprocating and self-rotating methods, the screened material enters the screening refinement bin 4 and is dispersed based on the self-rotating driving force applied by the polarizing element 3, completing the closed dust reduction operation during the screening process.

[0036] Specifically, the coupling component 6 includes a synchronous wheel 61 installed on the base 5, and a first-drive rotary joint 62 is coaxially installed on the synchronous wheel 61, and a second-drive rotary joint 63 is sleeved and installed on the first-drive rotary joint 62, wherein the first-drive rotary joint 62 and the second-drive rotary joint 63 are both constructed in a U-shape, and the first-drive rotary joint 62 and the second-drive rotary joint 63 are uniaxially penetrated at the front and rear ends, and arc contacts 64 are respectively integrally formed on the opposite end surfaces of the first-drive rotary joint 62 and the second-drive rotary joint 63, and the two arc contacts 64 have different diameters, wherein the arc contact 64 of the first-drive rotary joint 62 has a diameter greater than the arc contact 64 of the second-drive rotary joint 63. The diameter of the arc contact 64 is 0.17mm, and the upper and lower arc contacts 64 are connected at a single point, and the arc contact 64 with a larger diameter is located at the lower end, so as to enhance the gravity bearing value and cooperate with the base 5 to install a limiting sleeve 7 mounted on the outside of the coupling component 6.

During specific use, the crankshaft 33 rotates by the drive motor, and then moves synchronously with the connecting column 32 connected to the screening bin, so that it swings in the left and right directions, thereby realizing reciprocating screening of the material placed in the screening bin on the screening disc 11. At the same time, when the synchronous wheel 61 rotates, it engages with the driving wheel 34, causing the coupling component 6 to drive the screening bin 1 and the screening and refining bin 4 to rotate, and carry out subsequent bulking. A conical table is installed in the inner cavity of the bulk bin 43, so that the material can gather toward the inner ring wall of the bulk bin 43 after entering the bulk bin 43, which is convenient for centrifugal bulking.

[0038] Specifically, a bin opening is opened at the lower end of the screening bin 1, and a conical flexible rubber tube is installed between the clamping plate 35 and the port of the screening bin 1. In the present embodiment, the flexible rubber tube and the clamping plate 35 are movably installed through a T-slot clamp, so as to cooperate with the swing and rotation movement of the screening bin 1, wherein the dustproof bin 2 is provided with a conformal cover outside the screening bin 1, and support ribs are installed at a distance from the dustproof bin 2 for synchronous movement, and a screening material plate 11 is rotatably installed on the lower end surface of the screening bin 1.

The diameter of the sieve hole is smaller than the diameter of the sieve hole of the sieve plate 11.

A plurality of overflow holes are opened on the annular surface of the bulk bin 43, and the overflow holes pass through the inner cavity of the bulk bin 43 for overflow. A rubber buffer pad is laid on the lower end surface of the bulk bin 43. In specific use, the screened material passing through the screening bin 1 is scattered in the filter bin 41, and then the inclination setting of the lower end surface of the filter bin 41 satisfies the further refinement of the material screening and the collection of copper particles. The transition bin 42 tightens the material diffusion surface and then enters the bulk bin 43 for bulking. The bulk bin 43 is cylindrical, so that the scattering surface of the material is scattered in a small range and is easy to collect. In actual operation, the material is collected by wrapping a collection bag on the outer annular surface of the bulk bin 43 to complete the operation.

[0040] Embodiment 2

[0041] like Figure 6-Figure 7As shown, this embodiment is established on the basis of embodiment 1, and preferably, flip members 12 are installed on both side ends of the screening plate 11 for action, wherein the flip members 12 are symmetrical with respect to the central axis of the screening plate 11 as the baseline, and the two flip members 12 are respectively installed at the left and right ends of the screening plate 11, and the single flip member 12 includes a clamping head 121 partially embedded in the annular surface of the screening plate 11, and the clamping head 121 is installed with a connecting plate 122 that rotates away from the end surface of the screening plate 11, wherein the connecting plate 122 is eccentrically installed on the clamping head 121, and a driving motor is coaxially installed on the clamping head 121, and a bottom plate 123 is installed on the upper end surface of the connecting plate 122, and the bottom plate 123 is installed on the annular outer side wall of the screening bin 1, and a driving screw coaxially installed with a driving motor is installed on the bottom plate 123 and is screwed to the connecting plate 122 to realize the displacement of the connecting plate 122 in the vertical direction, and the two clamping heads 121 can control the screening plate 11, the action surfaces of the two clamping heads 121 are parallel, and the action points of the two clamping heads 121 are staggered, wherein the embedded point of the clamping head 121 located on the left side of the screening disc 11 is lower than the clamping head 121 located on the right side of the screening disc 11. In specific use, after completing the screening of the material in the screening bin within a preset time, the driving motor is driven by the main controller to realize the rotation of the driving screw, thereby realizing the displacement of the connecting plate 122 in the vertical direction, and after the driving screw rotates for a preset time, the two driving motors acting on the relative clamping heads 121 are driven in opposite directions to realize the rotation drive of the clamping heads 121, thereby driving the two clamping heads 121 to clamp and rotate the screening disc 11, thereby realizing that the material with larger diameter falls from the screening disc 11 to the screening and refining bin 4, preventing the copper powder particles with larger diameter from being unable to clean themselves after the screening is completed, resulting in the clogging of the screen and the loss of structural functionality.
