Description

Technical Field

[0002] The sulfuric acid process produces a large amount of waste acid. If it is concentrated and recycled as part of the raw materials, it will not only reduce environmental pollution, but also reduce the consumption of sulfuric acid. At present, most of my country's sulfuric acid process titanium dioxide plants are small in scale. According to the situation of these enterprises, a large amount of waste and by-products are generated in the production of titanium dioxide by sulfuric acid process, and the large amount of waste acid generated by titanium dioxide is a bottleneck problem restricting the clean production of titanium dioxide. Therefore, it is necessary to choose a reasonable large-scale, economical and high value-added way to concentrate on utilization.

[0003] When treating the existing waste acid, it is necessary to first add a neutralizing agent to the waste acid. When the waste acid and the reactant react completely and precipitate, the upper liquid after the reaction is extracted after it is precipitated to a solid-liquid separation state. However, adding the neutralizing agent to the waste acid requires personnel to continuously stir it, which is a large workload and low efficiency. At the same time, when extracting the liquid, some solids are easily extracted together, which is not conducive to subsequent processing by personnel. Based on this, we proposed a ferrous sulfate waste acid regulating tank. Utility Model Content

[0033] Furthermore, the water pump 6, the drive motor 9 and the three-phase asynchronous motor 37 are all electrically connected to an external power source.

[0034] Working principle: When personnel want to process waste acid, they first add waste acid into the stirring tank 1 from the liquid inlet pipe 4, and then add neutralizer into the stirring tank 1 from the liquid inlet pipe 4. At this time, the personnel start the drive motor 9, so that the output shaft of the drive motor 9 drives the stirring shaft 10 to rotate, and the stirring shaft 10 drives the first bevel gear 12 to rotate. The rotation of the first bevel gear 12 drives the second bevel gear 13 meshed with it to rotate around the corresponding rotating shaft 16. Since the second hollow tube 14 is fixedly connected to the peripheral side of the stirring shaft 10, the rotation of the stirring shaft 10 drives the second hollow tube 14 to rotate. At this time, the rotating shaft 16 is on the peripheral side of the second hollow tube 14. The second bevel gear 13 rotates around the stirring shaft 10 and the axis of the rotating shaft 16 at the same time. At this time, the rotating shaft 16 drives the stirring blade 18 in the clamping groove 17 to rotate. The stirring blade 18 rotates around the stirring shaft 10 and the axis of the rotating shaft 16 at the same time. At this time, the stirring blade 18 fully mixes the neutralizer and the waste acid. When the mixing is completed, the personnel turns off the drive motor 9 and stops stirring, so that the mixture of the waste acid and the neutralizer is precipitated in the stirring tank 1. When the precipitation is completed, the personnel starts the water pump 6, so that the water pump 6 extracts the precipitated mixture in the stirring tank 1 from the stirring tank 1. The liquid is discharged from the output end of the second transmission pipe 7 through the first transmission pipe 5 and falls on the filter screen 20. At this time, the solid in the mixture is filtered on the filter screen 20, and the liquid passes through the filter screen 20 and is discharged from the liquid outlet pipe 8, so that the personnel can perform subsequent processing on it. When the personnel want to clean the solid on the filter screen 20, the personnel start the three-phase asynchronous motor 37, so that the output shaft of the three-phase asynchronous motor 37 drives the positive and negative double-headed screw rod 35 to rotate, and the positive and negative double-headed screw rod 35 rotates so that the two adjustment blocks 33 threadedly connected to the positive and negative double-headed screw rod 35 move in opposite directions respectively, and through the second rotating column 32 The corresponding limit rod 30 is driven to move to the same side. At this time, the distance between the two adjustment blocks 33 gradually increases. The limit rod 30 drives the first rotating column 29 to move upward, so that the connecting block 28 drives the first rotating column 29 to move upward, and the connecting plate 27 drives the baffle door 26 to move upward. At this time, the baffle door 26 drives the corresponding sliding block 24 to slide upward in the sliding groove 23. Since the filter screen 20 is arranged at an angle, the solids filtered on the filter screen 20 can slide from the filter screen 20 to the direction of the give way groove 21 and slide out of the give way groove 21 to the outside, which is convenient for personnel to carry out subsequent processing of the separated solids.
