Description

Technical Field

[0001] The utility model belongs to the technical field of chemical production, and specifically relates to a premixing device. Background Art

[0002] The acid hydrolysis process adopts a production process of premixing before reaction. Premixing is carried out by mixing concentrated sulfuric acid and titanium ore. The premixed materials have high specific gravity and high solid content. It is easy to have local reactions, which will cause the discharge port of the premixing tank to be blocked and the materials cannot be discharged. This will affect production at the least and cause production accidents at the worst.

[0003] The existing premixing tank adopts a structure with a cylindrical upper part and a conical lower part. The discharge port uses an upper top valve, and intermittent operation causes the discharge port to be easily blocked. At the same time, the wall of the premixing tank is made of carbon steel, which is prone to produce scabbing material. The falling scabbing material can easily block the discharge port of the premixing tank.

[0004] Therefore, a premix device is needed to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, the utility model provides a premixing device, including a trough body, a rotating shaft, a frame and a driving motor. A discharge port is arranged at the bottom of the trough body, and a dome valve is arranged at the discharge port. The inner wall of the trough body is paved with a first acid-resistant ceramic tile, and the bottom wall of the trough body is provided with a slope composed of acid-resistant concrete, and the slope is paved with a second acid-resistant ceramic tile, and the top surface of the lower end of the second acid-resistant ceramic tile is flush with the bottom of the pipe of the discharge port so as to discharge the material; a trough cover is arranged on the top of the trough body, and a feed port, an acid inlet and an exhaust port are arranged on the trough cover, the rotating shaft is vertically arranged inside the trough body, an agitator is arranged at the bottom of the rotating shaft, and the top end of the rotating shaft passes through the trough cover, the driving motor is fixed above the trough cover through the frame, and the output shaft of the driving motor is connected to the top end of the rotating shaft through a reducer.

[0006] Optionally, a 4-6 mm thick rubber is coated between the first acid-resistant ceramic tile and the inner side wall of the trough body and between the second acid-resistant ceramic tile and the slope of the bottom of the trough body.

[0007] Optionally, the thickness of the first acid-resistant tile is 113 mm, and the thickness of the second acid-resistant tile is 65 mm.

[0008] Optionally, a filter is provided at the exhaust port of the tank cover.

[0009] Specifically, the filter is used to filter the exhausted gas.

[0010] Optionally, a bottom plate is provided below the trough body, and the bottom plate is made of I-beam.

[0011] Optionally, an inspection port and an inspection door are also provided on the shell of the tank body.

[0012] Specifically, the inspection opening and the inspection door facilitate the staff to inspect and repair the equipment inside the tank.

[0013] The utility model also includes other components that enable a premix device to be used normally, which are all conventional technical means in the art. In addition, the devices or components not limited in the utility model all adopt conventional technical means in the art, such as a drive motor and a dome valve.

[0014] The working principle of the utility model is to put titanium ore into the tank body through the feed port, input concentrated sulfuric acid into the tank body through the acid inlet, start the driving motor, drive the rotating shaft to rotate, and then drive the agitator to pre-mix the concentrated sulfuric acid and the titanium ore. After the mixing is completed, open the dome valve and discharge the material from the discharge port.

[0015] The beneficial effects of the utility model are:

[0016] 1. The inside of the tank is first lined with rubber and then acid-resistant tiles are laid to make the inner wall of the tank smooth and not easy to scar.

[0017] 2. The bottom structure of the tank is changed to a slope, and the top valve is changed to a dome valve, which solves the problem that the falling materials easily block the discharge port and valve. BRIEF DESCRIPTION OF THE DRAWINGS
