Description

Technical Field

[0001] This utility model relates to the field of zinc calcined ore production technology, specifically to a sludge treatment device for zinc calcined ore production. Background Technology

[0002] Zinc calcined ore is a product obtained by roasting zinc concentrate. It is a brown, granular solid. The production of zinc calcined ore generates a large amount of tail gas, which needs to be collected. The large amount of sulfur dioxide in the tail gas can be used in the production of sulfuric acid. Because the tail gas is at a high temperature and contains zinc calcined ore dust particles, it needs to be cooled by spraying before conversion. The spray water used in the spraying process needs to be repeatedly recycled. However, during the recycling process, the dust particle content in the spray water gradually increases. To avoid dust clogging the nozzles, recycling should not continue once the dust content becomes too high, and the water should be directly discharged.

[0003] The discharged wastewater enters the wastewater treatment pond for sedimentation and is reused. The sedimented sludge is scooped out, drained, and mixed with zinc concentrate, and then fed into a fluidized bed furnace for calcination to become zinc calcined sand.

[0004] However, currently, after the sludge is settled and drained, workers need to manually mix the sludge with the raw materials of zinc calcined sand, which is time-consuming and labor-intensive, resulting in low production efficiency of zinc calcined sand.

[0005] To address the aforementioned issues, this application proposes a sludge treatment device for zinc calcined ore production. Utility Model Content

[0006] This utility model aims to provide a sludge treatment device for zinc calcined ore production, which is mainly used to solve the problem that the sludge needs to be manually mixed with the raw materials of zinc calcined ore after sedimentation and water control, which is time-consuming and labor-intensive, resulting in low production efficiency of zinc calcined ore.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A sludge treatment device for zinc roasting production includes a box body with a feeding channel on one side and a discharge port at the bottom. Two symmetrically arranged first rotating rods are rotatably connected inside the box body. Each first rotating rod has a pressing roller fixedly connected to its outer wall. One end of each first rotating rod extends out of the box body and is fixedly connected to a spur gear. The two spur gears mesh with each other. A drive assembly is fixedly connected to one side of the box body. One end of one first rotating rod, away from the spur gear, extends out of the box body and is fixedly connected to the drive assembly. Symmetrical guide blocks are fixedly connected inside the box body between the feeding channel and the pressing roller. A stirring assembly is rotatably connected inside the box body below the pressing roller.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working Principle: When using this device, sludge and zinc calcined ore are fed into the box through the feeding channel. The drive component rotates the first rotating rod, and at the same time, the other first rotating rod rotates in the opposite direction through the engagement of a spur gear. The rolling roller fixed to the first rotating rod can crush the wet dust particles. After being crushed by the rolling roller, the dust particles continue to fall downwards. At the same time as the drive component operates, the stirring component operates, which can mix the sludge and zinc calcined ore evenly. After the sludge and zinc calcined ore are evenly mixed, the threaded cover is rotated to remove it, and the sludge and zinc calcined ore inside the box can be discharged through the discharge port and then fed into the fluidized bed furnace for calcination, becoming zinc calcined ore again.

[0011] 2. Beneficial Effects: During operation, the device uses a crushing roller to crush the dust particles inside the sludge and zinc calcined ore raw material. The crushed sludge and zinc calcined ore raw material fall into the inside of the chamber, where a stirring component mixes them evenly. After the evenly mixed sludge and zinc calcined ore raw material are discharged, they are fed into a fluidized bed furnace for calcination, turning them back into zinc calcined ore. This not only effectively reduces resource waste, but also makes mixing sludge and zinc calcined ore raw material more convenient, thus effectively improving the production efficiency of zinc calcined ore.

[0012] Preferably, the mixing assembly includes a second rotating rod rotatably connected inside the housing and below the crushing roller. A first bevel gear is fixedly connected to the outer wall of the second rotating rod. One end of the second rotating rod extends out of the housing and is fixedly connected to the drive assembly. A fixed plate is fixedly connected inside the housing below the first bevel gear. A third rotating rod passes through the fixed plate and is rotatably connected to the fixed plate. A second bevel gear is fixedly connected to the upper end of the third rotating rod. The first bevel gear meshes with the second bevel gear. Multiple stirring rods are fixedly connected to the outer wall of the third rotating rod. After being crushed by the crushing roller, the dust particles fall to the lower part of the housing. The second rotating rod rotates when the drive assembly operates. The rotation of the second rotating rod rotates the first bevel gear. Simultaneously, the rotation of the first bevel gear drives the third rotating rod to rotate synchronously through the meshing second bevel gear. The rotation of the third rotating rod, along with the multiple stirring rods on its outer wall, achieves a better mixing effect on the sludge and zinc calcined sand raw material inside the housing.

[0013] Preferably, the drive assembly includes a drive box fixedly connected to one side of the housing, a servo motor fixedly installed inside the drive box, and a drive wheel fixedly connected to the output end of the servo motor. One end of a first rotating rod, away from the spur gear, extends out of the housing and is fixedly connected to the drive wheel. One end of a second rotating rod extends out of the housing and is fixedly connected to a driven wheel. Belts are fitted onto the drive wheel and the driven wheel. When the device operates, the servo motor is powered on and started. The drive wheel drives the first rotating rod to rotate. Simultaneously, the rotation of the first rotating rod, through the engagement of the spur gear, causes another first rotating rod to rotate synchronously in the opposite direction. A crushing roller fixed to the first rotating rod can crush wet dust particles. Simultaneously, the rotation of the drive wheel drives the driven wheel via the belt, causing the driven wheel to rotate synchronously. The rotation of the driven wheel causes the second rotating rod to rotate synchronously. The rotation of the second rotating rod causes the first bevel gear to rotate. Simultaneously, the rotation of the first bevel gear, through the meshing second bevel gear, drives the third rotating rod to rotate synchronously. Simultaneously, the rotation of the third rotating rod, through multiple stirring rods on its outer wall, stirs and mixes the sludge and zinc calcined sand raw material inside the housing.

[0014] Preferably, multiple fixed rods are fixedly connected between the two guide blocks, and the fixed rods are linearly arrayed and equidistantly distributed between the two guide blocks. After the sludge and zinc calcined sand raw materials are added into the box through the feeding channel, the multiple fixed rods set between the two guide blocks can achieve a good screening effect. Small particles of sludge and zinc calcined sand raw materials will continue to fall downwards, while large particles of sludge and zinc calcined sand raw materials will be intercepted above the fixed rods. By activating the electric telescopic rod, the pressure plate can be moved downwards. The pressure plate squeezes the large particles of sludge and zinc calcined sand raw materials on the fixed rods, crushing them. The crushed large particles of sludge and zinc calcined sand raw materials continue to fall downwards and are crushed by the grinding rollers, thus achieving a better pulverization effect on the sludge and zinc calcined sand raw materials.

[0015] Preferably, a guide plate is fixedly connected inside the housing between the crushing roller and the mixing assembly, and the cross-section of the guide plate is inverted V-shaped. Through the guide plate inside the housing, the sludge and zinc calcined ore raw material crushed by the crushing roller falls onto the guide plate. The guide plate can effectively guide the sludge and zinc calcined ore raw material, thus preventing a large amount of sludge and zinc calcined ore raw material from falling onto the mixing assembly, thereby ensuring the normal operation of the mixing assembly inside the device. At the same time, the guide plate can also shield the first and second bevel gears to prevent solid materials from interfering with the operation of the bevel gears.

[0016] Preferably, multiple ventilation holes are provided on both sides of the drive box, and a filter screen is fixedly connected to the inner wall of each ventilation hole. When the servo motor inside the drive box operates, it will generate a certain amount of heat. The multiple ventilation holes on both sides of the drive box can effectively dissipate heat from the servo motor inside the drive box. The filter screens on the inner wall of the ventilation holes can effectively prevent external dust from entering the servo motor through the ventilation holes, thereby effectively ensuring the normal operation of the device.

[0017] Preferably, support legs are fixedly connected to the four corners of the bottom of the box to support the entire device, so that the discharge port can be easily connected to the fluidized bed combustion furnace of the next stage. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 A sludge treatment device for zinc calcined ore production includes a box body 1. Support legs 2 are fixedly connected to the four corners of the bottom of the box body 1. A feeding channel 3 is provided on one side of the box body 1. When the device is in use, sludge and zinc calcined ore raw materials are added into the box body 1 through the feeding channel 3.

[0025] like Figure 4 As shown, symmetrical first rotating rods 4 are rotatably connected inside the housing 1. Rolling rollers 5 are fixedly connected to the outer walls of both first rotating rods 4. One end of each of the two first rotating rods 4 extends out of the housing 1 and is fixedly connected to a spur gear 6 (e.g., ...). Figure 1 As shown), two spur gears 6 are meshed and connected; a drive assembly is fixedly connected to one side of the housing 1, in which one end of a first rotating rod 4 extends out of the housing 1 away from the spur gear 6 and is fixedly connected to the drive assembly.

[0026] The first rotating rod 4 can be rotated by the operation of the drive component. At the same time, the other first rotating rod 4 can be rotated in the opposite direction through the cooperation of the spur gear 6. The wet dust particles can be crushed by the crushing roller 5 fixed on the first rotating rod 4. Symmetrical guide blocks 7 are fixedly connected inside the box 1 between the feed channel 3 and the crushing roller 5. After the sludge and zinc calcined sand raw materials are added into the box 1 through the feed channel 3, the guide blocks 7 can play a good guiding role for the sludge and zinc calcined sand raw materials, so that the sludge and zinc calcined sand raw materials can fall exactly between the two crushing rollers 5.

[0027] Inside the housing 1, a stirring component is rotatably connected below the crushing roller 5. After being crushed by the crushing roller 5, the dust particles continue to fall downwards. The stirring component operates simultaneously with the driving component, which can mix the sludge and zinc calcined sand raw materials evenly. At the same time, the mixing of sludge and zinc calcined sand can also avoid uneven moisture levels in different parts of the mixed raw materials, which would lead to different combustion degrees in different parts of the mixed raw materials after entering the fluidized bed furnace. This would cause the iron ions in the raw materials to combine with other elements to form zinc ferrite, which is difficult to separate and is not conducive to the subsequent purification of zinc using zinc calcined sand.

[0028] like Figure 4 As shown, a guide plate 24 is fixedly connected inside the housing 1 between the rolling roller 5 and the mixing assembly. The cross-section of the guide plate 24 is set in an inverted V shape. The guide plate 24 can play a good guiding role for sludge and zinc calcined sand raw materials, which can effectively prevent a large amount of sludge and zinc calcined sand raw materials from falling onto the mixing assembly. This can effectively ensure the normal operation of the mixing assembly inside the device.

[0029] The bottom of the box 1 is provided with a discharge port 8. After the sludge and zinc calcined sand raw materials are mixed evenly, they are discharged through the discharge port 8 and then enter the fluidized bed furnace for calcination, where they are transformed into zinc calcined sand.

[0030] like Figure 3As shown, the mixing assembly includes a second rotating rod 10 rotatably connected inside the housing 1 below the rolling roller 5. A first bevel gear 11 is fixedly connected to the outer wall of the second rotating rod 10. One end of the second rotating rod 10 extends out of the housing 1 and is fixedly connected to the drive assembly. A fixing plate 12 is fixedly connected inside the housing 1 below the first bevel gear 11. A third rotating rod 13 passes through the fixing plate 12 and is rotatably connected to the fixing plate 12. A second bevel gear 14 is fixedly connected to the upper end of the third rotating rod 13. The first bevel gear 11 and the second bevel gear 14 are meshed together. Multiple stirring rods 15 are fixedly connected to the outer wall of the third rotating rod 13. After the dust particles are crushed by the crushing roller 5, they fall to the bottom of the box 1. During the falling process, the second rotating rod 10 can be rotated by the operation of the drive component. The rotation of the second rotating rod 10 can cause the first bevel gear 11 to rotate. At the same time, the rotation of the first bevel gear 11 can drive the third rotating rod 13 to rotate synchronously through the second bevel gear 14 that meshes with it. At the same time, the rotation of the third rotating rod 13 can achieve a better mixing effect on the sludge and zinc calcined sand raw material inside the box 1 through the multiple stirring rods 15 on its outer wall.

[0031] like Figure 2 and Figure 3 As shown, the drive assembly includes a drive box 16 fixedly connected to one side of the housing 1. A servo motor 17 is fixedly installed inside the drive box 16. Multiple ventilation holes 25 are provided on both sides of the drive box 16, and filters are fixedly connected to the inner walls of the ventilation holes 25. A drive wheel 18 is fixedly connected to the output end of the servo motor 17. One end of a first rotating rod 4, away from the spur gear 6, extends out of the housing 1 and is fixedly connected to the drive wheel 18. One end of a second rotating rod 10 extends out of the housing 1 and is fixedly connected to a driven wheel 19. A belt 20 is fitted onto the drive wheel 18 and the driven wheel 19. When the device is in operation, the servo motor 17 is powered on, and after the servo motor 17 is started, the first rotating rod 4 can be rotated through the drive wheel 18. While the first rotating rod 4 rotates, the other first rotating rod 4 can rotate synchronously in the opposite direction through the engagement of the spur gear 6. The rolling roller 5 fixed to the first rotating rod 4 can crush the wet dust particles. While the driving wheel 18 rotates, the driven wheel 19 can be driven through the belt 20, so that the driven wheel 19 rotates synchronously. When the driven wheel 19 rotates, the second rotating rod 10 can rotate synchronously. The rotation of the second rotating rod 10 can cause the first bevel gear 11 to rotate. While the first bevel gear 11 rotates, it can drive the third rotating rod 13 to rotate synchronously through the second bevel gear 14 meshing with it. While the third rotating rod 13 rotates, the sludge and zinc calcined sand raw materials inside the box 1 can be stirred and mixed through the multiple stirring rods 15 on its outer wall.

[0032] like Figure 4As shown, multiple fixing rods 26 are fixedly connected between the two guide blocks 7, and the fixing rods 26 are distributed in a linear array at equal intervals between the two guide blocks 7. After the sludge and zinc calcined sand raw materials are added into the box 1 through the feeding channel 3, the multiple fixing rods 26 set between the two guide blocks 7 can preferentially disrupt the clumps of sludge and zinc calcined sand raw materials and improve the degree of mixing.

[0033] As can be seen from the above, the specific embodiments of this utility model are as follows:

[0034] When using this device, first connect the power supply, then add the sludge and zinc calcined sand raw materials into the housing 1 through the feed channel 3. Small particles of sludge and zinc calcined sand raw materials will be distributed by the fixed rod 26 and continue to fall downwards. After starting the servo motor 17, the first rotating rod 4 can be rotated through the drive wheel 18. At the same time as the first rotating rod 4 rotates, the other first rotating rod 4 can be rotated in the opposite direction synchronously through the cooperation of the spur gear 6. The crushing roller 5 fixed on the first rotating rod 4 can crush the wet dust particles. After being crushed by the crushing roller 5, the dust particles will continue to fall downwards. At the same time as the drive wheel 18 rotates, the driven wheel 19 can be driven through the belt 20, thereby... The driven wheel 19 rotates synchronously, which causes the second rotating rod 10 to rotate synchronously. The rotation of the second rotating rod 10 causes the first bevel gear 11 to rotate. At the same time, the rotation of the first bevel gear 11 can drive the third rotating rod 13 to rotate synchronously through the second bevel gear 14 meshing with it. At the same time, the rotation of the third rotating rod 13 can beat, stir and mix the sludge and zinc calcined sand raw materials inside the box 1 through the multiple stirring rods 15 on its outer wall. After the sludge and zinc calcined sand raw materials are evenly mixed, the sludge and zinc calcined sand raw materials are discharged through the discharge port 8 and then enter the fluidized bed furnace for calcination, which turns them into zinc calcined sand. This can effectively improve the production efficiency of zinc calcined sand.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
