Description

Separation device for tin slag reduction machine

technical field

The utility model relates to the technical field of tin slag waste reduction equipment, in particular to a separation device for a fully automatic solder reduction machine.

Background technique

In the manufacturing process of our electronic products, the soldering of electronic components is generally performed with solder. During the welding process, tin slag will inevitably be generated, and the treatment of these tin slags has become a problem. The simplest, most trouble-free, and most wasteful treatment method is to sell the tin slag directly, that is, treat it as waste. If it is to be disposed of by the relevant government departments, the enterprise must bear a certain amount of disposal costs. Most manufacturers directly exchange tin bars with manufacturers, but this gives most of the benefits to the manufacturers who exchange tin bars. Moreover, if leaded and unleaded are accidentally mixed together during storage or transportation, the price will be far apart, and the exchange rate will naturally be very low, which is not conducive to saving costs for its enterprises.

In order to better save the cost of the enterprise, we invented the tin slag reduction machine. The working principle of the tin slag reduction machine is as follows: the tin slag is melted into liquid by heating, and the liquid solder is separated from the oxide by gravity. Oxide is not melted. Generally, the physical reduction method is used. It is impossible for the oxidized tin slag to be physically reduced to tin. We see that the so-called reduced tin is just pure tin mixed in the tin slag. High temperature, pressure and The friction of the reduction machine under working conditions will, on the contrary, re-oxidize the pure tin mixed in the tin slag when it is firmed. Therefore, we need to adopt an antioxidant, which requires non-sticky, non-corrosive properties, and has anti-oxidation and reduction functions.

The utility model patent No. 200520056267.9 filed by Shenzhen Emac Industrial Co., Ltd. on March 12, 2005 discloses a tin slag reducing machine, which includes a melting device 01, a separating device 02 and a motor 03. The melting device 01 includes a hopper and a heater around the hopper. A leak hole is provided at the bottom of the hopper, and the separation device 02 includes a separation cylinder 021 connected below the hopper. The top of the separation cylinder 021 is provided with a feed port 020 communicating with the leak hole of the hopper. The separation cylinder 021 is divided into an upper separation chamber 0211 and a lower separation chamber 0212 arranged side by side up and down and interpenetrating with each other. The first shaft 023 driven by the motor 03 is also arranged horizontally in the separation chamber 0211. The first shaft 023 is provided with several spiral conveying blades 0231 , the bottom edge of the spiral conveying blade 0231 slightly extends into the lower separation chamber 0212, and a first transmission gear 0232 is provided on one end of the first shaft 023; a waste residue outlet is provided at the bottom of one end of the upper separation chamber 0211 024. The second shaft 025 is also arranged horizontally in the lower separation chamber 0212. The second shaft 025 is provided with several crushing and stirring blades 0251, and one end of the second shaft 025 is also provided with a first transmission that can be connected with the first shaft 023. The gear 0232 meshes with the second transmission gear 0252; and the top of one end of the lower separation chamber 0212 is provided with an "n"-shaped guide tube 027, and the liquid inlet nozzle 0271 on one side of the guide tube 027 is located at the lower separation chamber 0212. In the cavity 0212, the liquid outlet nozzle 0272 on the other side is located outside the separation cylinder 021. The outlet pipe 0272 of the guide pipe 027 outside can be connected to a feeding device of a molding machine so that the outflowing pure tin can be directly molded.

When in use, first put the tin slag into the hopper 011 and start the heater to heat and melt the tin slag, then heat and melt the tin slag in the hopper and enter the separation cylinder 021 from the feed port 020 of the separation cylinder 021 through the bottom of the hopper and is accommodated in the lower separation chamber 0212; then the motor 03 drives the first shaft 023 to rotate, and then drives the second shaft 025 and the pulverizing and stirring blades 0252 on it to rotate synchronously to separate the components in the liquid tin slag , pure tin is deposited at the bottom, and various waste residues are floating on the surface of pure tin; the liquid level in the lower separation chamber 0212 rises to a certain height, and when the liquid level is higher than the highest point of the draft tube 027, at this time, the liquid The pure tin in the lower part enters the well of the diversion pipe 027 through the liquid inlet port 0271 of the diversion pipe 027, flows out from its liquid outlet port 0272 and enters the molding machine for molding, and at the same time, the waste residue is pushed to the waste residue outlet by the screw conveying blade 0231 Exit at 024.

The tin slag reduction machine with this structure first melts the tin slag in the melting device 01, and then separates the melted tin slag in the separation device 02, the pure tin deposits at the bottom, and the waste slag floats on the surface of the pure tin; the waste slag is conveyed by a screw The blade 0231 is pushed to the waste residue outlet 024 to be discharged. The separation device of this separation structure lacks an extrusion separation device, the purity of the separated pure tin cannot be guaranteed, and the separated waste residue also contains more tin, which causes a certain degree of waste of tin resources.
