Description

Technical Field

[0001] The present invention belongs to the technical field of high-lead-antimony separation, and in particular relates to a high-lead-antimony separation device and method. Background Art

[0002] The production process of antimony white can be divided into two categories: pyrometallurgy and wet metallurgy. Since the pyrometallurgy production process is relatively mature and stable, the production of antimony white generally adopts the pyrometallurgy process. The pyrometallurgy process usually uses refined antimony as raw material and obtains pure antimony white through steps such as melting, oxidation volatilization and rapid cooling.

[0003] Patent publication number CN1382815A discloses an apparatus for producing antimony white from a lead-antimony alloy, comprising an oxidation pot, a closed first reaction zone located above the oxidation pot, a second reaction zone, a cooling zone, a cyclone separator, an induced draft fan, and a dust collection and packaging chamber. This solution starts the induced draft fan to cool the air containing a large amount of antimony oxide generated by the reaction in the oxidation pot. The air is then separated from the trace lead, antimony vapor, and crude antimony oxide in the air by a cyclone separator, and then dust is collected through a bag filter to obtain qualified antimony oxide and antimony white. The resulting antimony white is not only of high purity but also has high production efficiency.

[0004] In the above scheme, trace lead, crude antimony and other impurities in the cooled air are separated by a cyclone separator. The existing cyclone separator mainly includes a conical separation barrel and a material collection box. The material collection box is sealed and connected to the conical separation barrel. When working, air is sucked into the conical separation barrel through the exhaust pipe, and the material is sucked into the conical separation barrel. The material entering the conical separation barrel is separated from the gas and solid particles by centrifugal force, and the solid particles will fall into the material collection box. The air mixed with antimony white dust is discharged from the exhaust pipe. However, during the operation of the cyclone separator, the material collection box cannot be opened. Once the material collection box is opened, the solid particles collected in the material collection box will be sucked away by the exhaust pipe. Therefore, when cleaning the solid particles inside the material collection box, the cyclone separator must be suspended. The suspension of the cyclone separator not only interrupts the continuity of the entire process operation, but also reduces the operating efficiency of the cyclone separator. For this reason, the present invention provides a high-lead-antimony separation device and method. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a high-lead antimony separation method described in the present invention comprises the following steps:

[0007] Step 1: The lead-antimony alloy after impurities removal is put into the oxidation pot through the feeding port to heat and melt, and then the slag is removed through the slag removal port until the lead-antimony melt becomes clean;

[0008] Step 2: Primary air is blown into the lead-antimony melt in the oxidation pot, and secondary air is simultaneously blown above the melt. A large amount of secondary air meets a large amount of volatile antimony formed by the primary air stirring the melt and the melt surface, and an oxidation reaction occurs, producing a large amount of air containing antimony oxide;

[0009] Step 3: Start the dust collecting fan. The air containing antimony oxide in step 2 is cooled and passed through a cyclone separator. The antimony white in the air is separated from other solid particles by the cyclone separator. At the same time, the separated solid particles are pre-stored at the bottom of the cyclone separator. Then, while ensuring the normal operation of the cyclone separator, the solid particles pre-stored in the cyclone separator are transported out through the discharge mechanism on the cyclone separator.

[0010] Step 4: The air mixed with antimony white is discharged from the cyclone separator and enters the dust collecting and packaging room, and finally antimony white that meets the requirements is obtained.

[0011] When the cyclone separator is processing air containing antimony oxide, the bulk particles in the cyclone separator are transported out while ensuring the internal air tightness of the cyclone separator, thereby improving the operating efficiency of the cyclone separator.

[0012] Preferably, a high-lead antimony separation device is suitable for the above-mentioned high-lead antimony separation method, comprising a separation barrel, an exhaust pipe fixedly connected to the upper end of the separation barrel, two sets of spiral plates fixedly coiled on the exhaust pipe, the outer ring of the spiral plate fits the inner wall of the separation barrel, the upper ends of the two sets of spiral plates are fixedly connected to the air inlet pipe, a collection box is fixedly installed at the lower end of the separation barrel, a discharging mechanism is provided in the collection box, the discharging mechanism comprises a spin-on roller, the spin-on roller is rotatably installed in the separation barrel, a first gear fixedly sleeved on the lower end of the spin-on roller, a second gear meshing with the first gear, and a drive shaft. The second gear is fixedly sleeved on the driving shaft, and the driving shaft is rotatably mounted on the outside of the collecting box, a connecting rod, one end of the connecting rod is hinged to shaft one, shaft one is fixedly mounted on the first gear, and shaft two is hinged to the other end of the connecting rod, a movable discharging block fixedly connected to shaft two, a discharge trough for placing solid particles is provided on the movable discharging block, a discharging nozzle is provided on one side of the lower end of the collecting box, the movable discharging block is movably plugged into the discharging nozzle, a discharge port is provided below the discharging nozzle, the discharge port is fixedly connected to the discharge pipe, a rectangular guide groove is provided in the discharging nozzle, and a feed port is provided on the upper side of the rectangular guide groove;

[0013] When cleaning the solid particles inside the collection box, without stopping the separation of the air containing antimony oxide, as the movable discharge block continuously moves back and forth along the rectangular guide groove, the discharge chute on the movable discharge block will continuously convey the solid particles inside the collection box out, realizing closed cleaning of the solid particles inside the collection box, which not only ensures the continuity of the entire process operation, but also improves the operating efficiency of the cyclone separator.

[0014] Preferably, the spin-joint roller includes a main shaft, which is rotatably mounted in the collection box, and the upper end of the main shaft extends into the separation barrel, and six sets of driven rods are hinged at the upper end of the main shaft at equal angles;

[0015] When solid particles fall into the collection box, they will hit the driven rod. The collision will cause the antimony white powder attached to the solid particles to be vibrated. The vibrated antimony white powder will be sucked away by the exhaust pipe, thereby improving the recovery rate of antimony white powder.

[0016] Preferably, the rotary roller also includes a movable shaft, which is movably mounted in the main shaft, six groups of push rods, and the six groups of push rods are fixedly mounted at equal angles on the movable shaft, a spring sleeved on the movable shaft, fixedly connected to the pressure-bearing shaft at the lower end of the movable shaft, and a sleeve sleeved on one end of the pressure-bearing shaft is rotatably mounted on a first rectangular groove. One end of the push rod is located in the first rectangular groove, and second rectangular grooves are provided on both sides of the first rectangular groove. A pin is fixedly mounted on one end of the push rod, and both ends of the pin are respectively located in the two groups of second rectangular grooves. One end of the spring is fixedly connected to the lower end of the movable shaft, and the other end of the spring is fixedly connected to the inner wall of the main shaft. A striking ball is provided at the end of the driven rod for knocking on the inner wall of the separation barrel, and the sleeve is close to the bottom of the collection box. Six groups of protrusions are provided at equal angles on the bottom of the collection box, and the protrusions are used to push the sleeve;

[0017] There are six groups of bumps at the bottom of the collection box. As the main shaft rotates continuously, the sleeve will be connected and squeezed by the six groups of bumps, so that the inner wall of the separation barrel will be continuously hit by the hitting ball. The continuous impact will cause the separation barrel to vibrate, so that the antimony white powder attached to the inner wall of the separation barrel will be vibrated up. The vibrated antimony white powder will be sucked away by the exhaust pipe, further improving the recovery rate of the antimony white powder.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. When cleaning the solid particles inside the collection box, without stopping the separation of the air containing antimony oxide, as the movable discharge block continuously moves back and forth along the rectangular guide groove, the discharge chute on the movable discharge block will continuously convey the solid particles inside the collection box out, realizing closed cleaning of the solid particles inside the collection box, which not only ensures the continuity of the entire process operation, but also improves the operating efficiency of the cyclone separator.

[0020] 2. When the first gear rotates, the first gear also drives the spin-on roller to rotate, and the spin-on roller will mobilize the six groups of driven rods to rotate together. As the six groups of driven rods rotate, the solid particles will hit the driven rods when they fall into the collection box. The collision will cause the antimony white powder attached to the solid particles to be vibrated, and the vibrated antimony white powder will be sucked away by the exhaust pipe, thereby improving the recovery rate of the antimony white powder.

[0021] 3. In the process of the main shaft and the driven rod rotating together, the main shaft will drive the pressure-bearing shaft and the sleeve to rotate together. As the sleeve rotates, the sleeve will pass through the convex block, and the sleeve will be squeezed by the convex block, so that the sleeve drives the pressure-bearing shaft, the movable shaft, and the push rod to move downward together, and the movable shaft further stretches the spring, and at the same time, the push rod drives the pin shaft to squeeze the inner wall of the second rectangular groove on the driven rod, so that the driven rod rotates downward, and the hitting ball on the driven rod will hit the inner wall of the separation barrel until the sleeve misses the convex block. Under the action of the spring rebound force, the hitting ball will break away from and put into contact with the inner wall of the separation barrel, and at the same time, the sleeve will be close to the bottom of the collection box again. Since there are six groups of protrusions at the bottom of the collection box, as the main shaft continues to rotate, the sleeve will be connected and squeezed by the six groups of protrusions, so that the inner wall of the separation barrel is continuously hit by the hitting ball. The continuous impact causes the separation barrel to vibrate, so that the antimony white powder attached to the inner wall of the separation barrel is vibrated, and the vibrated antimony white powder will be sucked away by the exhaust pipe, further improving the recovery rate of antimony white powder.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0032] Example 1

[0033] A method for separating high-lead antimony, comprising the following steps:

[0034] Step 1: The lead-antimony alloy after impurities removal is put into the oxidation pot through the feeding port to heat and melt, and then the slag is removed through the slag removal port until the lead-antimony melt becomes clean;

[0035] Step 2: Primary air is blown into the lead-antimony melt in the oxidation pot, and secondary air is simultaneously blown above the melt. A large amount of secondary air meets a large amount of volatile antimony formed by the primary air stirring the melt and the melt surface, and an oxidation reaction occurs, producing a large amount of air containing antimony oxide;

[0036] Step 3: Start the dust collecting fan. The air containing antimony oxide in step 2 is cooled and passed through a cyclone separator. The antimony oxide in the air is separated from other solid particles by the cyclone separator. The separated solid particles are stored in the bottom of the cyclone separator. Then, while ensuring the normal operation of the cyclone separator, the solid particles stored in the cyclone separator are transported out through the discharge mechanism 6 on the cyclone separator.

[0037] Step 4: The air mixed with antimony white is discharged from the cyclone separator and enters the dust collecting and packaging room, and finally antimony white that meets the requirements is obtained.

[0038] Furthermore, in order to optimize the high-lead antimony separation method, the embodiment of the present invention improves the cyclone separator and sets the discharge mechanism 6 so that the cyclone separator can transport the body particles in the cyclone separator out while ensuring the internal air tightness of the cyclone separator during the process of separating the air containing antimony oxide, thereby improving the operating efficiency of the cyclone separator.

[0039] Example 2

[0040] like Figures 1 to 3 As shown, a high-lead antimony separation device is suitable for the above-mentioned high-lead antimony separation method, including a separation barrel 1, an exhaust pipe 2 is fixedly inserted at the upper end of the separation barrel 1, two groups of spiral plates 3 are fixedly coiled on the exhaust pipe 2, the outer ring of the spiral plate 3 fits the inner wall of the separation barrel 1, and the upper ends of the two groups of spiral plates 3 are fixedly connected to the air inlet pipe 4, a collecting box 5 is fixedly installed at the lower end of the separation barrel 1, and a discharging mechanism 6 is arranged in the collecting box 5, and the discharging mechanism 6 includes a rotary roller 601, the rotary roller 601 is rotatably installed in the separation barrel 1, a first gear 602 fixedly sleeved on the lower end of the rotary roller 601, a second gear 603 meshing with the first gear 602, and a driving shaft 604, and the second gear 603 is fixedly sleeved on the driving shaft 604, driving The movable shaft 604 is rotatably mounted on the outer side of the collecting box 5, the connecting rod 606, one end of the connecting rod 606 is hinged to shaft one 605, shaft one 605 is fixedly mounted on the first gear 602, shaft two 607 is hinged to the other end of the connecting rod 606, a movable discharging block 608 is fixedly connected to shaft two 607, a discharge trough 6081 for placing solid particles is provided on the movable discharging block 608, a discharge nozzle 501 is provided on one side of the lower end of the collecting box 5, the movable discharging block 608 is movably plugged into the discharge nozzle 501, a discharge port 502 is provided below the discharge nozzle 501, the discharge port 502 is fixedly connected to the discharge pipe 505, a rectangular guide groove 503 is provided in the discharge nozzle 501, and a feed port 504 is provided on the upper side of the rectangular guide groove 503.

[0041] Specifically, the collecting box 5 is made of transparent plastic, and the movable discharge block 608 is coated with a rubber layer to enhance the sealing between the movable discharge block 608 and the inner wall of the discharge nozzle 501. The upper end of the exhaust pipe 2 is connected to the air inlet of the induced draft fan, and the air inlet pipe 4 is connected to the pipeline for conveying air containing antimony oxide. In the initial state, the discharge nozzle 501 is blocked by the movable discharge block 608, and the feed port 504 is directly opposite to the discharge trough 6081 on the movable discharge block 608. The slot width of the discharge trough 6081 is smaller than the distance between the feed port 504 and the discharge port 502. When it is necessary to separate the air containing antimony oxide, the induced draft fan is started. , so that the air containing antimony oxide is sucked into the air inlet pipe 4, and the air will rotate downward along the flow channel between the two sets of spiral plates 3. Under the action of centrifugal force, the solid particles in the air are separated from the gas mixed with antimony white powder, and the solid particles flow along the inner cavity of the separation barrel 1 into the collection box 5, so that the solid particles are pre-stored in the collection box 5. At the same time, the gas mixed with antimony white powder is extracted from the inside of the separation barrel 1 by the exhaust pipe 2. As the solid particles accumulate inside the collection box 5, the solid particles will fall into the discharge chute 6081 through the feed port 504. At this time, the second gear 603 is driven to rotate by the motor, and the second gear The wheel 603 drives the first gear 602 to rotate. As the first gear 602 rotates, the first gear 602 cooperates with the connecting rod 606, the shaft 1 605, and the shaft 2 607 to make the movable discharge block 608 reciprocate along the rectangular guide groove 503. During the reciprocating movement of the movable discharge block 608, when the movable discharge block 608 moves toward the outside of the discharge nozzle 501, the solid particles in the discharge chute 6081 are also transported toward the outside of the discharge nozzle 501. At the same time, the discharge chute 6081 will stagger the feed port 504, so that the feed port 504 is blocked by the movable discharge block 608 until the discharge chute 6081 is opened. 81 is facing the discharge port 502, so that the solid particles in the discharge trough 6081 are discharged into the discharge pipe 505 through the discharge port 502. Compared with the prior art, when cleaning the solid particles inside the collecting box 5, without stopping the separation of the air containing antimony oxide, as the movable discharge block 608 continuously moves back and forth along the rectangular guide groove 503, the discharge trough 6081 on the movable discharge block 608 will continuously convey the solid particles inside the collecting box 5 to realize closed cleaning of the solid particles inside the collecting box 5, which not only ensures the continuity of the entire process operation, but also the operation efficiency of the cyclone separator.

[0042] like Figures 4 to 7 As shown, the rotary roller 601 includes a main shaft 6011, which is rotatably installed in the collection box 5, and the upper end of the main shaft 6011 extends into the separation barrel 1, and six groups of driven rods 6012 are hinged at the upper end of the main shaft 6011 at equal angles.

[0043] Specifically, when the air containing antimony oxide is separated as described above, most of the gas mixed with antimony white powder in the air will be extracted by the exhaust pipe 2, and a small amount of antimony white powder will adhere to the solid particles. As the solid particles fall into the collection box 5, another small amount of antimony white powder will adhere to the inner wall of the separation barrel 1. Therefore, when the first gear 602 rotates, the first gear 602 also drives the rotary roller 601 to rotate, and the rotary roller 601 will mobilize the six groups of driven rods 6012 to rotate together. As the six groups of driven rods 6012 rotate, the solid particles will collide with the driven rods 6012 in the process of falling into the collection box 5. The collision will cause the antimony white powder attached to the solid particles to be vibrated, and the vibrated antimony white powder will be extracted by the exhaust pipe 2, thereby improving the recovery rate of antimony white powder.

[0044] Furthermore, the rotary roller 601 further includes a movable shaft 6013, which is movably mounted in the main shaft 6011, six sets of push rods 6014, and the six sets of push rods 6014 are fixedly mounted on the movable shaft 6013 at equal angles, a spring 6015 sleeved on the movable shaft 6013, a pressure shaft 6016 fixedly connected to the lower end of the movable shaft 6013, a sleeve 6017 rotatably sleeved on one end of the pressure shaft 6016, a first rectangular groove 122 is opened on the driven rod 6012, one end of the push rod 6014 is located in the first rectangular groove 122, and the first rectangular groove 122 is provided. 2, a second rectangular groove 123 is formed on both sides thereof. A pin 141 is fixedly mounted on one end of the push rod 6014. Both ends of the pin 141 are respectively located in the two sets of second rectangular grooves 123. One end of a spring 6015 is fixedly connected to the lower end of the movable shaft 6013, and the other end of the spring 6015 is fixedly connected to the inner wall of the main shaft 6011. A striking ball 121 is provided at the end of the driven rod 6012 for striking the inner wall of the separation barrel 1. The shaft sleeve 6017 is closely attached to the bottom of the collection box 5. Six groups of protrusions 506 are provided at equal angles on the bottom of the collection box 5. The protrusions 506 are used to push the shaft sleeve 6017.

[0045] Specifically, the spring 6015 is in a stretched state. When the main shaft 6011 rotates together with the driven rod 6012, the main shaft 6011 will drive the pressure shaft 6016 to rotate together with the sleeve 6017. As the sleeve 6017 rotates, the sleeve 6017 will pass through the bump 506, and the sleeve 6017 is squeezed by the bump 506, so that the sleeve 6017 drives the pressure shaft 6016, the movable shaft 6013, and the push rod 6014 to move downward together, and the movable shaft 6013 further stretches the spring 6015. At the same time, the push rod 6014 drives the pin 141 to squeeze the inner wall of the second rectangular groove 123 on the driven rod 6012, so that the driven rod 6012 rotates downward, and the driven rod 6012 rotates downward. The hitting ball 121 on 012 will hit the inner wall of the separation barrel 1 until the sleeve 6017 is offset from the protrusion 506. Under the rebound force of the spring 6015, the hitting ball 121 will be separated from the inner wall of the separation barrel 1 and put into contact with the inner wall of the separation barrel 1. At the same time, the sleeve 6017 will be close to the bottom of the collection box 5 again. Since six groups of protrusions 506 are provided at the bottom of the collection box 5, as the main shaft 6011 continues to rotate, the sleeve 6017 will be connected and squeezed by the six groups of protrusions 506, so that the inner wall of the separation barrel 1 is continuously hit by the hitting ball 121. The continuous impact causes the separation barrel 1 to vibrate, so that the antimony white powder attached to the inner wall of the separation barrel 1 is vibrated, and the vibrated antimony white powder will be sucked away by the exhaust pipe 2, further improving the recovery rate of the antimony white powder.

[0046] Working principle: Start the induced draft fan to suck the air containing antimony oxide into the air inlet pipe 4, and the air will rotate downward along the flow channel between the two sets of spiral plates 3. Under the action of centrifugal force, the solid particles in the air are separated from the gas mixed with antimony white powder, and the solid particles flow along the inner cavity of the separation barrel 1 into the collection box 5, so that the solid particles are pre-stored in the collection box 5. At the same time, the gas mixed with antimony white powder is extracted from the inside of the separation barrel 1 by the exhaust pipe 2. As the solid particles accumulate inside the collection box 5, the solid particles will fall into the discharge chute 6081 through the feed port 504. At this time, the second gear 603 is driven to rotate by the motor, and the second gear 603 drives the first gear 602 to rotate. As the first gear 602 rotates, the first gear 602 cooperates with the connecting rod 606, shaft 1 605, and shaft 2 607. The movable discharge block 608 is made to reciprocate along the rectangular guide groove 503. During the reciprocating movement of the movable discharge block 608, when the movable discharge block 608 moves toward the outside of the discharge nozzle 501, the solid particles in the discharge chute 6081 are also conveyed toward the outside of the discharge nozzle 501. At the same time, the discharge chute 6081 will stagger the feed port 504, so that the feed port 504 is blocked by the movable discharge block 608, until the discharge chute 6081 is directly opposite the discharge port 502, so that the solid particles in the discharge chute 6081 are discharged into the discharge pipe 505 through the discharge port 502. As the movable discharge block 608 continuously reciprocates along the rectangular guide groove 503, the discharge chute 6081 on the movable discharge block 608 will continuously convey the solid particles inside the collection box 5, thereby realizing closed cleaning of the solid particles inside the collection box 5.

[0047] When the first gear 602 rotates, the first gear 602 also drives the rotary roller 601 to rotate, and the rotary roller 601 will mobilize the six groups of driven rods 6012 to rotate together. As the six groups of driven rods 6012 rotate, the solid particles will hit the driven rods 6012 in the process of falling into the collection box 5. The collision will cause the antimony white powder attached to the solid particles to be vibrated. As the main shaft 6011 rotates together with the driven rods 6012, the main shaft 6011 will drive the pressure shaft 6016 to rotate together with the sleeve 6017. As the sleeve 6017 rotates, the sleeve 6017 will pass through the protrusion 506, and the sleeve 6017 is squeezed by the protrusion 506, so that the sleeve 6017 drives the pressure shaft 6016, the movable shaft 6013, and the push rod 6014 to move downward together, and the movable shaft 6013 further stretches the spring 601. 5. At the same time, the push rod 6014 drives the pin 141 to squeeze the inner wall of the second rectangular groove 123 on the driven rod 6012, so that the driven rod 6012 rotates downward, and the hitting ball 121 on the driven rod 6012 will hit the inner wall of the separation barrel 1 until the sleeve 6017 staggers the protrusion 506. Under the action of the rebound force of the spring 6015, the hitting ball 121 will be separated from the inner wall of the separation barrel 1 and put into contact with it. At the same time, the sleeve 6017 will be close to the bottom of the collection box 5 again. Since six groups of protrusions 506 are provided at the bottom of the collection box 5, as the main shaft 6011 continues to rotate, the sleeve 6017 will be continuously squeezed by the six groups of protrusions 506, so that the inner wall of the separation barrel 1 is continuously hit by the hitting ball 121. The continuous impact causes the separation barrel 1 to vibrate, so that the antimony white powder attached to the inner wall of the separation barrel 1 is vibrated, and the vibrated antimony white powder will be sucked away by the exhaust pipe 2.
