[0030] The spray part 18 includes an atomizing nozzle 19; a through hole is opened at one end of the surface of the partition 17, and there are several atomizing nozzles 19, which are arranged at the top of the inner wall of the dust removal shell 6. The number of the atomizing nozzles 19 is 8-12, preferably 10. A tank body 21 is fixedly installed on the top surface of the dust removal shell 6. The top of the atomizing nozzle 19 is connected to the inside of the tank body 21 through a liquid inlet pipe 20. The exhaust pipe 22 is located on the side away from the through hole. A baffle 30 is fixed on the top of the inner wall of the dust removal shell 6 on the side of the exhaust pipe 22.

[0031] See also Figure 4-5 The sealing assembly 24 includes a reset spring 27; a notch is provided at the top of the inner wall of the isolation cover 3 on the front side of the connecting pipe 23, a rotating shaft 26 is arranged inside the notch, both ends of the rotating shaft 26 are rotatably connected to the inner wall of the notch, both ends of the rotating shaft 26 are fixedly connected to the sealing plate 25 through a connecting bracket, the reset spring 27 is sleeved in the middle of the rotating shaft 26, the other end of the reset spring 27 is fixed to the top of the inner wall of the isolation cover 3, the top of the inner wall of the isolation cover 3 is located in front of the sealing plate 25 and a second fixed block 28 is symmetrically fixed thereto, a second spring 29 is fixed on the surface of the second fixed block 28, and the other end of the second spring 29 is fixed to the surface of the sealing plate 25.

[0032] like Figure 1-5 As shown, a bonding silver wire production feeding device of the utility model is used. When in use, the top end of the feeding plate 2 is installed correspondingly to the tail end of the feeding belt, and the silver block falls on the surface of the feeding plate 2 through the feeding mechanism. The silver block slides downward through the inclined setting of the feeding plate 2. When it moves to the position of the sealing component 24, the silver block squeezes the sealing plate 25 and enters the feeding pipeline through the feeding plate 2. Then the feeding port of the melting furnace is opened, and the silver block enters the melting furnace for melting and casting. After the sealing plate 25 rotates, the reset spring 27 and the second spring 29 are stretched. The elastic force of the reset spring 27 and the second spring 29 is used to return the sealing plate 25 to its original position, so that the sealing plate 25 maintains sealing, thereby preventing the high-temperature flue gas inside the melting furnace from leaking into the air when the feeding port of the melting furnace is opened.

[0033] After the silver block enters the melting furnace, it will inevitably squeeze out the high-temperature flue gas inside it, and the high-temperature flue gas can enter the dust removal component 5 through the connecting pipe 23 after escaping. The high-temperature flue gas first enters the cooling part 7 at the bottom end of the dust removal shell 6;

[0034] In the cooling part 7, cooling water enters the water storage tank 8 through the cooling water inlet pipe, then flows into another water storage tank 8 through the heat dissipation pipe 9, and finally is discharged through the cooling water outlet pipe. In this process, the high-temperature flue gas is fully in contact with the heat dissipation pipe 9, and a plurality of heat dissipation fins 10 are sleeved on the surface of the heat dissipation pipe 9. The number of heat dissipation fins 10 is 400-600, preferably 500, which can expand the contact area with the high-temperature flue gas, thereby quickly cooling the high-temperature flue gas.

[0035] After the cooling treatment, the smoke enters the filter part 11, and the smoke first passes through the mobile filter 13 and enters the filter layer 14. The filter layer 14 is filled with a number of activated carbon particles, and the activated carbon particles filter the smoke, thereby absorbing the particles in the smoke. The first fixed block 16 and the first spring 15 enable the mobile filter 13 to always squeeze the filter layer 14, maintain the tightness of the filter layer 14, and reduce the flow rate of the smoke, so as to achieve a better filtering effect.

[0036] After filtering, the flue gas enters the spray part 18 through the through holes on the surface of the partition 17. Since the through holes and the exhaust pipe 22 are respectively located on both sides of the dust removal shell 6, during the flow of the flue gas, a number of atomizing nozzles 19 can atomize the alkali solution stored in the tank body 21 and spray it out, thereby converting harmful substances in the flue gas into harmless substances to purify the flue gas. After purification, the flue gas can be discharged through the exhaust pipe 22.

[0037] It is worth noting that the entire device is controlled by a main control button. Since the device matched with the control button is a common device and belongs to the existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described here.
