Description

Technical Field

[0001] This utility model relates to the field of high-purity copper sputtering and purification technology, and in particular to a high-purity copper sputtering and purification device. Background Technology

[0002] Smelting and purification is a method to remove impurities from metals and improve their purity through melting, stirring, and cooling. It can be used for the purification of high-purity copper targets. Therefore, a continuous feeding smelting device for high-purity copper purification, with publication number CN220398199U, is described. An electric telescopic rod pushes a cover plate, along with a sealing plate, away from the opening of the feed box to feed material into the feed box. After feeding is completed, the cover plate and sealing plate return to their original positions, keeping the feed box sealed. Then, the partition is pulled to allow the raw material entering the feed box to fall into the smelting furnace. After the raw material falls into the smelting furnace, the operator can release the pull on the partition. At this time, the return spring resets, and the partition, with the cooperation of the slider and the slide groove, allows one end of the partition to enter the groove on the inner wall of the feed box, thus re-fixing the partition in the feed box.

[0003] However, during the feeding process, opening the baffle causes some of the heat inside the smelting furnace to enter above the baffle. Even after the baffle is closed after feeding is complete, this heat may still be lost and come into contact with the air or personnel when the cover is opened. In order to maintain the high-temperature environment inside the smelting furnace, additional energy is needed to replenish the lost heat, which not only increases energy consumption but may also lead to an increase in production costs. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing a high-purity copper target smelting and purification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a high-purity copper target smelting and purification device, comprising a smelting furnace body and a feeding box, wherein a screw feeder is provided at the outlet of the feeding box, and a feeding pipe communicating with the furnace cover of the smelting furnace body is provided at the outlet of the screw feeder, the upper opening of the feeding box is located away from the smelting furnace body, and a feeding box is slidably installed inside the feeding box, a piston plate is slidably installed inside the feeding box, and the bottom edge of the side plate of the feeding box near the smelting furnace body is hollowed out, an opening and closing plate is inserted into the hollowed-out part of the feeding box, the feeding box is inclined, and a pneumatic telescopic rod is fixedly installed at the top of the feeding box near the smelting furnace body, the telescopic end of the pneumatic telescopic rod extends into the feeding box and is fixedly installed with a lap strip, the side of the opening and closing plate is inserted into the side plate of the feeding box, and a retaining strip for overlapping with the lap strip is fixedly installed at the top edge of the opening and closing plate.

[0006] Preferably, an electric telescopic rod is fixedly installed through the side of the feeding box away from the smelting furnace body, and the telescopic end of the electric telescopic rod extends into the feeding box and is used to push the feeding box to slide.

[0007] Preferably, an electric push rod is fixedly installed through the side plate of the feeding box away from the smelting furnace body. The telescopic end of the electric push rod is used to push the piston plate to slide, and the cylinder part of the electric push rod is inserted through the surface of the feeding box.

[0008] Preferably, a connecting pipe that is detachably connected to the furnace cover of the smelting furnace is fixedly installed through the middle of the bottom surface of the feed pipe.

[0009] Preferably, the bottom of the feed pipe is sloped on the side near the screw feeder, and the top of the slope is close to the screw feeder.

[0010] Preferably, the bottom of the feed pipe is a flat surface located on the side of the connecting pipe away from the screw feeder, and a piston block is slidably installed thereon.

[0011] Preferably, a baffle is fixedly installed at the bottom of the feed pipe on the side away from the screw feeder at the top of the connecting pipe, and the top edge of the baffle is clearance-fitted with the top edge of the feed pipe.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, a feeding box is set in the feeding hopper to transport the target material, and a piston plate is set in the feeding box. The target material in the feeding box moves towards the open opening plate under the action of gravity and enters the screw feeder. At this time, some of the heat in the melting furnace will enter the feeding box, but it will not leak from the opening of the feeding box. After the target material in the feeding box is unloaded, the piston plate moves in the feeding box, so that the heat in the feeding box can be squeezed out of the feeding box along the open opening plate and re-enter the melting furnace. Then the opening plate closes again, the piston plate resets, and the feeding box resets. That is, no heat loss from the melting furnace is caused during the process.

[0014] 2. In this utility model, the piston block is set up so that when the feeding box moves to the right, the piston block moves to the right under the action of air pressure, thus ensuring that the air pressure inside the smelting furnace remains unchanged. Similarly, when the feeding box moves to the left to reset, the piston block will move to the left, which can also ensure that the air pressure inside the smelting furnace remains constant.

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] like Figures 1-4 As shown, a high-purity copper target smelting and purification device includes a smelting furnace body 1 and a feeding box 4. A screw feeder 3 is provided at the outlet of the feeding box 4. A feeding pipe 2 connected to the furnace cover of the smelting furnace body 1 is provided at the outlet of the screw feeder 3. The target material enters the screw feeder 3 through the feeding box 4, enters the feeding pipe 2 under the transport action of the screw feeder 3, and finally slides into the smelting furnace body 1 through the feeding pipe 2.

[0023] The top opening of the feeding box 4 is positioned away from the melting furnace body 1, and a feeding casket 7 is slidably installed inside the feeding box 4. The target material entering the feeding box 4 falls into the feeding casket 7. A piston plate 9 is slidably installed inside the feeding casket 7, and the bottom edge of the side plate of the feeding casket 7 closest to the melting furnace body 1 is hollowed out. An opening and closing plate 12 is inserted into the hollowed-out part of the feeding casket 7. The feeding casket 7 moves within the feeding box 4 until it is offset from the opening of the feeding box 4. This is achieved by installing sealing gaskets around the feeding casket 7. Now that the openings of the feeding box 7 and the feeding hopper 4 are offset, the internal space of the feeding box 7 is independent. After the opening plate 12 moves upward and opens, the target material inside the feeding box 7 moves towards the opened opening plate 12 under the action of gravity and enters the screw feeder 3. At this time, the inside of the feeding box 7 is connected to the screw feeder 3, the feed pipe 2, and the melting furnace body 1. At this time, some of the heat from the melting furnace body 1 will enter the feeding box 7, but it will not leak from the opening of the feeding hopper 4. After the target material is unloaded from the feeding box 7, the piston plate 9 moves within the feeding box 7, allowing the heat inside the feeding box 7 to be expelled along the opened opening and closing plate 12 and re-enter the melting furnace body 1. The feeding box 4 is tilted, and a pneumatic telescopic rod 8 is fixedly installed at the top of the feeding box 7 near the melting furnace body 1. The telescopic end of the pneumatic telescopic rod 8 extends into the feeding box 4 and is fixedly installed with a connecting strip 14. The side of the opening and closing plate 12 is inserted into the side plate of the feeding box 7, and a locking strip 13 for overlapping with the connecting strip 14 is fixedly installed at the top edge of the opening and closing plate 12. After the feeding box 7 moves to a position offset from the opening of the feeding box 4, it continues to move until the locking strip 13 overlaps with the top edge of the connecting strip 14. The pneumatic telescopic rod 8 then retracts, causing the connecting strip 14 to drive the locking strip 13 and the opening and closing plate 12 to rise and open against gravity. When the connecting strip 14 and the locking strip 13 overlap, the opening and closing plate 12 opens and closes with the extension and retraction of the pneumatic telescopic rod 8.

[0024] An electric telescopic rod 5 is fixedly installed through the side of the feeding box 4 away from the melting furnace body 1. The telescopic end of the electric telescopic rod 5 extends into the feeding box 4 and is used to push the feeding box 7 to slide. The telescopic end of the electric telescopic rod 5 is fixedly connected to the side of the feeding box 7.

[0025] An electric push rod 6 is fixedly installed through the side plate of the feeding box 7 away from the melting furnace body 1. The telescopic end of the electric push rod 6 is used to push the piston plate 9 to slide, and the cylinder part of the electric push rod 6 is inserted through the surface of the feeding box 4. The telescopic end of the electric push rod 6 is connected to the side of the piston plate 9 by bolts. In addition, the piston plate 9 in this solution can be made easy to move back and reset when the opening and closing plate 12 closes the cutout of the feeding box 7 by setting a one-way valve on its surface.

[0026] A connecting pipe 15, detachably connected to the furnace cover of the smelting furnace body 1, is fixedly installed through the middle of the bottom surface of the feed pipe 2. The bottom of the feed pipe 2 is sloped on the side near the screw feeder 3, with the top of the slope close to the screw feeder 3. The bottom of the feed pipe 2, on the side away from the screw feeder 3 via the connecting pipe 15, is flat and has a piston block 10 slidably installed thereon. A baffle 11 is fixedly installed inside the bottom of the feed pipe 2 on the side away from the screw feeder 3 via the top of the connecting pipe 15. The top edge of the baffle 11 is clearance-fitted with the top edge inside the feed pipe 2. When the target material flowing out of the outlet of the screw feeder 3 automatically slides down the slope on the left side of the bottom of the feed pipe 2, and... The target material, blocked by the baffle 11, eventually enters the smelting furnace 1 along the connecting pipe 15. The purpose of setting the piston block 10 in this scheme is that when the feeding box 7 moves to the right in the feeding box 4, it will push and compress the air in the feeding box 4. In order to prevent the air pressure in the smelting furnace 1 from increasing as the feeding box 7 moves to the right, the piston block 10 is set up so that when the feeding box 7 moves to the right, the piston block 10 moves to the right under the action of air pressure, thus ensuring that the air pressure in the smelting furnace 1 remains unchanged. Similarly, when the feeding box 7 moves to the left to reset, the piston block 10 will move to the left, which can also ensure that the air pressure in the smelting furnace 1 remains constant.

[0027] The working principle is as follows: the target material is put into the feeding box 7 through the opening of the feeding box 4 until the feeding box 7 is full. Then the feeding box 7 moves to the right and is offset from the opening of the feeding box 4. It continues to move until the top edge of the clamping strip 13 overlaps with the overlapping strip 14. The pneumatic telescopic rod 8 retracts, so that the overlapping strip 14 drives the clamping strip 13 and the opening and closing plate 12 to rise and open against the action of gravity. The target material in the feeding box 7 moves towards the opening and closing plate 12 under the action of gravity and enters the screw feeder 3. Under the transportation action of the screw feeder 3, it enters the feed pipe 2 and finally slides into the melting furnace body 1 through the feed pipe 2.

[0028] The wiring diagrams of the screw feeder 3, electric telescopic rod 5, electric push rod 6, and pneumatic telescopic rod 8 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the screw feeder 3, electric telescopic rod 5, electric push rod 6, and pneumatic telescopic rod 8 will not be explained in detail.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
