Description

TECHNICAL FIELD

[0002] The main purpose of mixing ilmenite with concentrated sulfuric acid is to extract titanium, which is a key step in the production of titanium dioxide by the sulfuric acid method. However, ordinary flow meters are generally not suitable for directly measuring the flow of concentrated sulfuric acid, mainly due to the following reasons:

[0003] (1) Corrosion problem

[0004] Concentrated sulfuric acid (especially with a concentration of ≥70%) is highly corrosive, and the materials of ordinary flow meters (such as carbon steel, copper, or stainless steel that is not resistant to acid) can be corroded, leading to equipment damage, shortened lifespan, and decreased measurement accuracy (such as corrosion of electrodes or sensors).

[0005] (2) Viscosity and flowability

[0006] Concentrated sulfuric acid has high viscosity (especially at low temperatures or high concentrations), which can affect the sensitivity of certain flow meters (such as turbine and vortex types) or cause increased pressure loss.

[0007] (3) Conductivity limitation

[0008] Concentrated sulfuric acid has low conductivity, and ordinary electromagnetic flow meters (which rely on the conductivity of the fluid) may not work.

[0009] For the proportioning of liquid sulfuric acid, although it can be configured by test tube volume, multiple steps are required in each proportioning process to achieve accurate proportioning of sulfuric acid, making the entire operation process tedious and time-consuming, increasing the workload and the possibility of errors. Especially when liquid sulfuric acid is frequently proportioned, the tedious steps not only reduce work efficiency, but also can cause fatigue of the operator, affecting overall production efficiency and accuracy.

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.

[0028] Example 1

[0029] like Figures 1-4 As shown, this utility model provides a technical solution: an adjustable ratio intermittent premixing device for ilmenite-sulfuric acid, such as... Figure 1 As shown, the device includes a housing 1, a transparent storage cavity 4 at the top of the housing 1, a flow divider 9 at the bottom of the storage cavity 4, and two sets of flow holes 12 opposite to each other on the flow divider 9. One set of flow holes 12 is connected to an external sulfuric acid storage container through a curved pipe 11, and the other set of flow holes 12 is connected to the inside of the housing 1 through a connecting pipe 10. The opening and closing of the two sets of flow holes 12 are controlled by a control device, and the opening and closing states of the two sets of flow holes 12 are opposite.

[0030] like Figure 3 As shown, a slide plate 6 is slidably connected to the inner wall of the storage cavity 4, a slide rod 5 is fixedly connected to the top of the slide plate 6, a support groove is opened on the outer periphery of the slide plate 6, a piston ring 7 is fixedly connected to the inner wall of the support groove, and a base plate 8 is fixedly connected to the bottom of the slide plate 6.

[0031] like Figure 2As shown, a fixed plate 3 is provided in the middle of the outer wall of the storage cavity 4. Two hydraulic cylinders 21 are embedded and connected inside the fixed plate 3. The piston rod of the hydraulic cylinder 21 is located above the cylinder. A support plate 20 is fixedly connected between the top ends of the two hydraulic cylinders 21. The bottom of the support plate 20 is fixedly connected to the top end of the slide rod 5.

[0032] like Figure 3 and Figure 4 As shown, the two-part diversion hole 12 includes a first diversion hole and a second diversion hole. The bottom of the first diversion hole is fixedly connected to a connecting pipe 10, and the bottom of the second diversion hole is connected to a curved pipe 11.

[0033] like Figure 1 As shown, multiple support legs 2 are fixedly connected to the top of the device housing 1, and a fixed plate 3 is fixedly connected to the top of the support legs 2.

[0034] The control device includes a controller and two fluoropolymer-lined solenoid valves; the two fluoropolymer-lined solenoid valves are respectively installed on the side of the connecting pipe 10 and the curved pipe 11 near the storage chamber 4, and are respectively connected to the controller in communication.

[0035] Storage chamber 4 is a vinyl ester resin fiberglass container, and the outside of storage chamber 4 is marked with graduations.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that the storage cavity 4 in this embodiment is semi-transparent, and additives are added to the vinyl ester resin.

[0038] Working principle:

[0039] like Figures 1-4 As shown, when concentrated sulfuric acid is injected into the outer casing 1 of the device, the fluoropolymer-lined solenoid valve on the connecting pipe 10 opens, the fluoropolymer-lined solenoid valve on the curved pipe 11 closes, and the hydraulic cylinder 21 drives the slide bar 5 and the slide plate 6 to slide downwards, pushing the concentrated sulfuric acid downwards (the concentrated sulfuric acid has a high viscosity).

[0040] After all the concentrated sulfuric acid in the storage chamber 4 is transferred into the outer shell 1 of the device, the fluoropolymer-lined solenoid valve on the connecting pipe 10 is closed and the fluoropolymer-lined solenoid valve on the curved pipe 11 is opened; at the same time, the hydraulic cylinder 21 drives the slide bar 5 and the slide plate 6 to slide upward until the slide plate 6 moves to the set scale.

[0041] Since the storage chamber 4 is a vinyl ester resin fiberglass container, the level of concentrated sulfuric acid in the storage chamber 4 can be observed through the outer wall of the storage chamber 4. After the set level is reached, the fluoropolymer-lined solenoid valve on the curved pipe 11 is closed.

[0042] 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.
