[0002] Sponge copper can be extracted from waste copper and ore. It is a copper material with a porous structure. It has a wide range of applications in many fields due to its high specific surface area, excellent electrical conductivity and thermal conductivity. High-grade sponge copper can be used to refine metallic copper, make raw materials such as cuprous octoate, and can also be used in processes such as die casting.

[0003] Different from direct leaching preparation, extracting sponge copper from metal ore also requires the raw ore to be made into mineral powder through coarse grinding, fine grinding and fine grinding. When the mineral powder particles reach the specifications suitable for leaching, the raw mineral powder needs to be calcined in a calcining furnace. However, during the calcination process, the mineral powder will be blown out by the airflow due to turnover, resulting in the loss of mineral powder, and a large amount of various components will precipitate from the mineral powder. There are many harmful components in these substances. Traditional air filtration equipment is prone to blockage of exhaust components.

[0021] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0022] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0023] A sponge copper calcining device for metal purification provided by some embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0024] Embodiment 1: Combination Figure 1-Figure 11 As shown, a sponge copper calcining device for metal purification provided by the present invention comprises a horizontal calcining furnace 100 and a plurality of discharge pipes 200 arranged at the bottom of the horizontal calcining furnace 100 and used for releasing the calcined ore powder, a furnace top energy supply mechanism 300 arranged on the horizontal calcining furnace 100, a plurality of groups of ore dust collecting mechanisms 400 and a plurality of groups of neutralization and air filtering mechanisms 500 arranged on the furnace top energy supply mechanism 300, and a transfer pipe 600 is arranged between adjacent groups of ore dust collecting mechanisms 400 and neutralization and air filtering mechanisms 500, and an exhaust pipe 700 is arranged in the neutralization and air filtering mechanism 500.

[0025] The horizontal calcining furnace 100 is composed of an outer furnace and a core furnace, and an end pipe with ring teeth is provided at one end of the core furnace, and the end pipe penetrates to the outside of the outer furnace; A plurality of discharge pipes 200 are used to release the calcined ore powder; The furnace top energy supply mechanism 300 is used to provide kinetic energy for dust collection and scale scraping of multiple groups of mineral material dust collection mechanisms 400 and multiple groups of neutralization and air filtering mechanisms 500; The ore dust collecting mechanism 400 includes a base 410 disposed on the air hole at the top of the horizontal calcining furnace 100, a vertical pipe 420 disposed in the base 410, two sets of vibration generating components 430 disposed on the top of the base 410, a dust collecting bin 440 mounted on the vertical pipe 420, and a filter hopper 450 movably mounted on the top of the inner cavity of the dust collecting bin 440; One end of the diversion pipe 600 is mounted on the dust collecting bin 440; The neutralization and air filtering mechanism 500 includes a liquid storage bin 510 disposed on the other end of the transfer tube 600, a separation pad 520 installed inside the liquid storage bin 510, and an annular scraper 590 disposed in the inner cavity of the liquid storage bin 510; The length of the end tube of one end of the transfer tube 600 is the same as the length of the top pipe of the dust collecting bin 440, and the length of the end tube of the other end of the transfer tube 600 is the same as the depth of the inner cavity of the liquid storage bin 510; The deflector pipe 600 and the exhaust pipe 700 are both made of stainless steel, and the inner walls of the deflector pipe 600 and the exhaust pipe 700 are coated with an anti-corrosion coating.

[0026] Calcination is a method of refining ore after multiple grinding after collection. After the ore is coarsely ground, finely ground and finely ground, the finely ground ore powder needs to be put into the calciner for roasting. When a large amount of gas is released from the ore powder due to calcination, the hot steam flow will lift the ore powder up, and the total amount of calcined ore powder will eventually decrease. At the same time, the external airflow will also pollute the working environment. In addition, harmful gases mixed in the hot steam flow will also cause corrosion to the metal exhaust pipe, which will seriously reduce the service life of the equipment.

[0027] When the hot steam flow of the gear lever carries the mineral powder upward, the mineral powder accumulated on the inner wall of the vertical pipe 420 and the dust collecting bin 440 will fall down due to the wave radiation of the vibration component 430, and the mineral powder rising along the air flow will be captured by the high-frequency lifting filter 450, and finally the mineral powder particles in the hot steam flow can be effectively screened out to avoid the reduction of the total amount of mineral powder in the core furnace; A plurality of evenly distributed ore dust collecting mechanisms 400 are installed on the air holes at the top of the horizontal calcining furnace 100, and a plurality of neutralizing and filtering mechanisms 500 are arranged on the other side of the top of the horizontal calcining furnace 100. When it is necessary to clean a harmful gas unique to the hot steam flow, the following diagram can be used. Figure 1 The plurality of transfer tubes 600 are arranged in a manner; When it is necessary to clean the various components mixed in the hot steam flow, it is necessary to use multiple deflector tubes 600 to connect the multiple liquid storage bins 510 in sequence, and connect the outer end of the deflector tube 600 installed in the latter liquid storage bin 510 to the hole in the previous liquid storage bin 510 where the second pull plate 570 is placed. At this time, the various components in the hot steam flow can be effectively cleaned.

[0028] Embodiment 2: Combination Figure 3-Figure 11 As shown, based on Example 1, the furnace top energy supply mechanism 300 includes a dual-axis motor 330 and four sets of transmission components 340 as well as a first top support 310 and three second top supports 320; The first support 310 is composed of a first arc plate and a chassis, and the second support 320 is composed of a second arc plate and two L-shaped support rods, and the number of the L-shaped support rods is three groups.

[0029] Preferably, the first arc plate and the three second arc plates are used to block the high temperature of calcination to prevent heat energy from radiating to the multiple liquid storage bins 510, ensuring that the reaction of the hot vapor flow with various solutions will not be affected by the heat energy and cause reverse reaction.

[0030] The first arc plate and the second arc plate are both provided with columns 370, and a main clamping ring 380 is installed on the column 370, and a secondary clamping ring 390 is installed on the main clamping ring 380. Combination bolts are arranged in the adjacent ends of the main clamping ring 380 and the secondary clamping ring 390, and the combined main clamping ring 380 and the secondary clamping ring 390 are used to provide sufficient compressive support for the liquid storage tank 510.

[0031] Preferably, two sets of main clamp rings 380 and auxiliary clamp rings 390 are installed on the column 370, and the combined main clamp rings 380 and auxiliary clamp rings 390 are only a way to fix the liquid storage tank 510. According to the stability requirements of the operation of the liquid storage tank 510, the liquid storage tank 510 can be fixed to the arc plate by welding.

[0032] Two sets of transmission components 340 are installed on both ends of the transmission shaft in the dual-axis motor 330, and the remaining three sets of transmission components 340 are respectively arranged on three sets of L-shaped support rods; The four transmission components 340 on one side of the transmission shaft are connected to the first transmission belt 350, and the four transmission components 340 on the other side of the transmission shaft are connected to the second transmission belt 360; The transmission assembly 340 includes a wheel disc 341, an auxiliary shaft 342 is installed in the middle of the inner side of the wheel disc 341, and a bearing is installed inside the auxiliary shaft 342, and the top end of the L-shaped support rod is installed in the bearing; A first pin 343 is installed on the outer side of the wheel disc 341 at a position deviating from the center of the circle.

[0033] Preferably, the first transmission belt 350 and the second transmission belt 360 drive the multiple transmission components 340 in a way of supplying energy. According to the stability of the energy supply, the first transmission belt 350 and the second transmission belt 360 can be set as chains of the same specification. In this case, a ring gear can be welded in the annular groove of the auxiliary shaft 342, and the transmission rod is driven by the meshing of the gear and the chain, thereby ensuring that the evenly distributed multiple wheel discs 341 rotate more smoothly. At the same time, the four transmission components 340 arranged on one side of the transmission shaft can make the filter bucket 450 rise and fall horizontally stably through the operation of the chain drive mode; The four transmission assemblies 340 arranged on the other side of the transmission shaft operate in a chain manner so that the annular scraper 590 exerts a greater thrust on the scale during the lifting and lowering, thereby improving the effectiveness of scale removal.

[0034] Embodiment 3: Combination Figure 9-11 As shown, based on Example 1, the mineral dust collection mechanism 400 further includes two sets of traction components 460 disposed in the dust collecting bin 440 and two first covers 470 installed on the dust collecting bin 440; The inner wall of the dust collecting bin 440 is provided with two symmetrically distributed slots; The traction assembly 460 includes a first slide plate 461 disposed in a slot, a second pin 462 mounted on the first slide plate 461, a first pull plate 463 movably mounted on the second pin 462, an anti-slip rod 464 mounted on the top of the first slide plate 461, and a spring 465 disposed outside the anti-slip rod 464; An end plate is disposed on the inner side of the top of the first slide plate 461 , and the two end plates on the inner sides of two adjacent first slide plates 461 are mounted on the filter bucket 450 .

[0035] Preferably, the length of the first slide plate 461 is twice the length of the slot of the dust collecting bin 440. When the first slide plate 461 is pulled up and down regularly by constant pressure, the two adjacent first slide plates 461 can control the filter bucket 450 to rise and fall stably along the inner wall of the dust collecting bin 440. Finally, the airflow rising along the inner cavity of the dust collecting bin 440 and the vertical pipe 420 can be quickly captured by the high-frequency rising and falling filter bucket 450, thereby avoiding the loss of the total amount of mineral powder inside the core furnace.

[0036] The vibration-generating assembly 430 includes a base 431 installed on the top of the base 410, and two brackets on the top of the base 431 are provided with a slideway, and a compression spring 432 and a shaft sleeve 433 are provided in the slideway; A shaft rod 434 is movably mounted in two adjacent shaft sleeves 433 , a suspension 435 is movably mounted outside the shaft rod 434 , and a cushion block 436 is mounted at the bottom end of the suspension 435 ; A limit rod 437 is installed on the base 431, and a slide groove adapted to the limit rod 437 is opened in the plate at the top of the suspension 435; The inner cavity of the vertical pipe 420 is in communication with the inner cavity of the dust collecting bin 440, and the cushion block 436 is used to provide impact waves for the mineral powder accumulated on the inner wall of the cavity.

[0037] Preferably, the limit rod 437 fixed on the base 431 can provide a restraining force to prevent the obliquely lifted suspension 435 from tilting. When the bottom end of the first slide plate 461 extends to the bottom of the dust collecting bin 440, the bottom end of the first slide plate 461 contacts and squeezes the suspension 435, and the cushion block 436 installed at the bottom end of the suspension 435 can cooperate with the two compression springs 432 to provide a resonance force to the dust collecting bin 440 and the vertical pipe 420 as a whole. Finally, the mineral powder attached to the inner wall of the vertical pipe 420 and the dust collecting bin 440 can be effectively shaken away.

[0038] Embodiment 4: Combination Figure 6-Figure 8 As shown, based on Example 1, the neutralization and air filtering mechanism 500 further includes a linkage assembly 560 disposed in the liquid storage bin 510; The linkage assembly 560 includes a second slide plate 561, a third pin 562 installed on the outer side of the top of the second slide plate 561, a clamp 563 installed on the inner side of the top of the second slide plate 561, and a guide rod 580 installed in the clamp 563; The separation pad 520 is composed of a bottom plate and a partition plate, and a gas filter window is provided on one side of the bottom plate, and a sliding sleeve is provided on the other side of the bottom plate, and the guide rod 580 is adapted to penetrate into the sliding sleeve; Preferably, the separation pad 520 is fixed in the inner cavity of the liquid storage tank 510 to provide auxiliary pressure for the lifting rod of the guide rod 580 to ensure that the guide rod 580 does not shake during the pressure applied by the annular scraper 590. At the same time, the partition inside the separation pad 520 can also block the output airflow to avoid mixing of the mixed airflow and the cleaned airflow.

[0039] The annular scraper 590 is mounted on the bottom end of the guide rod 580; The neutralization and air filtering mechanism 500 further includes a second pull plate 570, four second sealing covers 550, and a sewage pipe 530 disposed in the liquid storage bin 510; The top of the sewage pipe 530 is a trumpet-shaped structure, and a sealing head 540 is installed on the threaded section at the outer end of the sewage pipe 530.

[0040] Preferably, the sewage pipe 530 and the liquid storage tank 510 are assembled structures. In this case, the sewage pipe 530 serves as a carrier of scale. When the number of mechanisms increases, there is some corrosive scale that will not directly contact the bottom of the inner cavity of the liquid storage tank 510. At this time, the bottom of the liquid storage tank 510 can provide sufficient compressive support for the sewage pipe 530. When the annular scraper 590 is reciprocatingly lifted, the scale on the inner wall of the liquid storage tank 510 can enter the inner cavity of the sewage pipe 530 and be stored at the moment of scraping and crushing under pressure, so as to reduce the obstruction of the crushing mechanism to the output airflow of the annular scraper 590.

[0041] The working principle and use process of the present invention: As a calcination method for preparing sponge copper, the collected ore needs to be finely processed by grinding equipment in advance, and the fine ore powder obtained after fine processing needs to be put into the calcination furnace for calcination, and the calcined product can react better with the subsequent leaching compound; When the horizontal calcining furnace 100 is erected, the end hole of the gear pipe at one end of the horizontal calcining furnace 100 will be connected to the hopper. As the ore powder is put into the hopper, the ore powder will eventually be stored in the core furnace inside the horizontal calcining furnace 100 for calcination. During the calcining process, the sulfur component substance or other component substances in the ore powder will evaporate and be discharged from the air holes at the top of the horizontal calcining furnace 100 along with the hot steam flow. Finally, the sulfur component substance and other component substances will enter the inner cavity of the dust collecting bin 440 from the vertical pipe 420; As the dual-axis motor 330 starts and runs, its internal transmission shaft will simultaneously drive two of the transmission components 340, and the three transmission components 340 arranged on the other three second top supports 320 can be jointly driven by the first transmission belt 350 and the second transmission belt 360. At this time, the four transmission components 340 evenly distributed on one side of the transmission shaft will simultaneously drive the multiple first pull plates 463 to reciprocate and extend, and the first pull plates 463 will pull the second pin 462, the first slide plate 461 and the filter bucket 450 to reciprocate and rise. The filter hopper 450 can collect the mineral powder dust floating up with the airflow, and finally sink under the action of high-frequency lifting vibration. At the same time, after the first slide plate 461 drops to the bottom of the dust collecting bin 440, the bottom of the first slide plate 461 will hit the suspension 435 at high frequency. With the cooperation of the base 431 and the limit rod 437, the suspension 435 and the cushion block 436 can hit the fan-shaped plate at the bottom of the dust collecting bin 440. At this time, the core furnace can be prevented from rotating, causing the hot airflow to entrain and discharge the mineral powder; After the mineral powder in the upward airflow is cleaned, the remaining airflow will be transferred from the transfer pipe 600 to the solution in the inner cavity of the liquid storage bin 510. When the sulfur component gas passes through the alkaline solution in the liquid storage bin 510 for filtration and reaction, the sulfur component in the hot steam flow can be adsorbed and removed. The remaining airflow can be discharged outward from the exhaust pipe 700; The evenly distributed multiple transfer pipes 600 in the attached drawings of the specification are only the arrangement for adsorbing the sulfur component in the hot steam flow. When it is necessary to adsorb the other components in the hot steam flow, the evenly distributed multiple liquid storage bins 510 can be connected in sequence by using the multiple transfer pipes 600. At this time, the inner cavities of the multiple liquid storage bins 510 need to be injected with corresponding neutralizing solutions according to the different components to be adsorbed. As the hot steam flow passes through the multiple transfer pipes 600 and the multiple liquid storage bins 510 in sequence, the various components mixed in the hot steam flow can be completely cleaned. At the same time, the multiple transmission components 340 evenly distributed on the other side of the transmission shaft will simultaneously drive the multiple second pull plates 570 to reciprocate and extend, and the other end of the second pull plate 570 will drive the third pin 562, the second slide plate 561, the clamp 563 and the guide rod 580 to reciprocate and rise and fall. At this time, the annular scraper 590 of the mounting rod at the bottom end of the guide rod 580 can remove the scale deposited on the inner wall of the liquid storage tank 510, and the head 540 can be taken out during the timing period, so that the deposited scale can be quickly removed; The above two methods of treating hot steam both involve adsorption of harmful components.

[0042] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
