Abstract
The utility model relates to a sulphuric acid conveying system of titanium white powder production, its characterized in that: a liquid outlet pipe (3) at the bottom of the concentrated sulfuric acid metering bin (1) is connected into a mixing tank (5), and a stirrer (6) is arranged in the mixing tank (5); the liquid outlet pipe (3) is connected with an emptying pipe B (4), and the emptying pipe B (4) is fixed on one side of the concentrated sulfuric acid metering bin (1) through a fixing frame (8); be equipped with evacuation pipe A (2) and pneumatic valve F2 on concentrated sulfuric acid metering storehouse (1), the inlet of concentrated sulfuric acid metering storehouse (1) is equipped with flexible coupling (7). Design simple structure through for concentrated sulfuric acid outlet pipe on the line installation evacuation pipe with stabilize the steelframe, with the flexible coupling combined action, eliminated because concentrated sulfuric acid outlet pipe line has improved the security of production because the vibrations that the negative pressure caused.
Description
Technical Field
The utility model belongs to the technical field of chemical production, concretely relates to sulphuric acid conveying system of titanium white powder production.
Background
In the production process of titanium dioxide, ilmenite and concentrated sulfuric acid are used as raw materials, ilmenite and concentrated sulfuric acid are added into a mixing tank and mixed and then are placed into an acidolysis pot, a certain position difference exists between a concentrated sulfuric acid metering bin and the mixing tank in the vertical direction and the horizontal direction, concentrated sulfuric acid in the sulfuric acid metering bin is added into the mixing tank, after the concentrated sulfuric acid is added, vacuum is formed in a concentrated sulfuric acid outlet pipeline, negative pressure is generated, air quickly enters a vacuum pipeline, an air hammer is formed, violent vibration of the concentrated sulfuric acid outlet pipeline is caused, huge sound is generated after the pipeline collides with a wall, and the loose weld of the concentrated sulfuric acid outlet pipeline and the damage to the wall concrete structure contacted with the pipeline are caused in the past for a long time.
Disclosure of Invention
The utility model discloses a not enough of prior art is avoided to the purpose, provides a sulphuric acid conveying system of titanium white powder production.
In order to achieve the purpose, the utility model adopts the technical proposal that: a sulphuric acid conveying system of titanium white production which characterized in that: a liquid outlet pipe at the bottom of the concentrated sulfuric acid metering bin is connected into a mixing tank, and a stirrer is arranged in the mixing tank; the liquid outlet pipe is connected with an emptying pipe B, and the emptying pipe B is fixed on one side of the concentrated sulfuric acid metering bin through a fixing frame; the concentrated sulfuric acid metering bin is provided with an emptying pipe A and a pneumatic valve F2, and a liquid inlet of the concentrated sulfuric acid metering bin is provided with a flexible connection.
The method is characterized in that: and a manual valve F1, a pneumatic valve F2 and a flexible connection are arranged on the liquid outlet pipe.
The top of each of the emptying pipe A and the emptying pipe B is in a semicircular arc shape with a downward opening.
The utility model has the advantages that: design simple structure through for concentrated sulfuric acid outlet pipe on the line installation evacuation pipe with stabilize the steelframe, with the flexible coupling combined action, eliminated because concentrated sulfuric acid outlet pipe line because of the vibrations that the negative pressure caused, reduced the maintenance volume of pipeline and to the damage of wall, improved the security in the production process.
Drawings
FIG. 1 is a schematic view of the present invention;
in the figure: 1-concentrated sulfuric acid metering bin, 2-emptying pipe A, 3-liquid outlet pipe, 4-emptying pipe B, 5-mixing tank, 6-stirrer, 7-flexible connection, 8-fixing frame, F1-manual valve and F2-pneumatic valve.
Detailed Description
Embodiment 1, a sulphuric acid conveying system of titanium white production, its characterized in that: a liquid outlet pipe 3 at the bottom of the concentrated sulfuric acid metering bin 1 is connected into a mixing tank 5, and a stirrer 6 is arranged in the mixing tank 5; the liquid outlet pipe 3 is connected with an emptying pipe B4, and the emptying pipe B4 is fixed on one side of the concentrated sulfuric acid metering bin 1 through a fixing frame 8; the concentrated sulfuric acid metering bin 1 is provided with an emptying pipe A2 and a pneumatic valve F2, and a liquid inlet of the concentrated sulfuric acid metering bin 1 is provided with a flexible connection 7.
And a manual valve F1, a pneumatic valve F2 and a flexible connection 7 are arranged on the liquid outlet pipe 3.
The top of each of the emptying pipe A2 and the emptying pipe B4 is in a semicircular arc shape with a downward opening.
The working process is as follows: concentrated sulfuric acid is added through the flexible coupling 7 of 1 inlet in concentrated sulfuric acid measurement storehouse, gets into mixing tank 5 through drain pipe 3, adds the design volume after, closes pneumatic valve F2 on the drain pipe 3, and concentrated sulfuric acid flows to this pneumatic valve F2 back end pipeline, owing to designed evacuation pipe B4 on this back end pipeline, this part can not form the vacuum, can't form the air hammer, avoids the vibrations of drain pipe 3. The top of the emptying pipe B4 is a semicircular arc with a downward opening, so that rainwater is prevented from entering the sulfuric acid metering bin through the emptying pipe.
