[0002] As an important inorganic chemical product, titanium dioxide has excellent whiteness, hiding power and weather resistance, and is widely used in many fields such as coatings, plastics, papermaking, and inks. In modern industrial production, the quality and output of titanium dioxide play a vital role in the development of related industries. After searching, the Chinese patent authorization number CN221656575U discloses a hydrolysis device for titanium dioxide production, which relates to the technical field of titanium dioxide production devices, including a tank body, a feed pipe 1, a feed pipe 2, a pressure relief valve, a steam main pipe, a steam branch pipe, a motor, a stirring device and a discharge port; the feed pipe 1, the feed pipe 2, the pressure relief valve and the steam main pipe are arranged at the top of the tank body, and the discharge port is arranged at the lower part of the tank body. The steam main pipe is annular, and the steam branch pipes are evenly vertically arranged in the tank body and connected to the steam main pipe. Each steam branch pipe is evenly provided with an air outlet, the motor is installed at the top of the tank body, and the stirring device is connected to the power output end of the motor. The present application can solve the problem that the titanium liquid in the upper and lower areas of the existing hydrolysis device is unevenly heated to cause temperature difference, and that stirring with straight blades evenly stirs and breaks up the secondary agglomerates while also easily destroying the primary agglomerates, thereby reducing the performance of titanium dioxide.

[0003] The above-mentioned patent discloses a hydrolysis device for titanium dioxide production, which has the following shortcomings: the steam input through the steam main pipe in this solution can evenly contact and heat the titanium liquid, solving the problem that the existing steam will cool down during the movement from bottom to top, resulting in uneven heating of the titanium liquid in the upper and lower areas. Although this solution can heat titanium liquids at different heights, the steam main pipe is fixed and the titanium liquid is only heated by stirring the titanium liquid with a stirring rod. The heating efficiency needs to be improved. For this purpose, a hydrolysis production device for titanium dioxide is designed. Utility Model Content

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] Reference Figure 1-Figure 5, a hydrolysis production equipment for titanium dioxide, including a tank body 1, an air inlet pipe 5 is sleeved on the top of the tank body 1, a circular hole adapted for the air inlet pipe 5 is opened on the top of the tank body 1, a control valve 501 is fixedly installed on the top of the air inlet pipe 5, and a rotary joint 10 is fixedly connected to the bottom of the air inlet pipe 5, and an air guide cylinder 11 is fixedly connected to the bottom of the rotary joint 10, and three L-shaped guide tubes 7 are fixedly connected to the outer surface of the circumference of the air guide cylinder 11 at equal distances, each L-shaped guide tube 7 is provided with a plurality of air outlet pipes 701, and each air outlet pipe 701 is facing the central axis of the tank body 1, and a driven disk 8 is fixedly connected to the bottom of the air guide cylinder 11 through a connecting column, and two blocks 801 are symmetrically fixedly connected to the two ends of the bottom of the driven disk 8. Through the rotation of the three L-shaped guide tubes 7, the raw materials located at any position inside the tank body 1 can be exposed to heat at the first time.

[0023] In this embodiment, a motor 6 is fixedly connected to the bottom of the tank body 1 near the center, and the top output end of the motor 6 passes through the tank body 1 and is fixedly connected to a rotating rod 601. The top of the rotating rod 601 is fixedly connected to a turntable 9. An arc-shaped notch 901 is provided on the turntable 9, and the arc-shaped notch 901 is adapted to the block 801.

[0024] In this embodiment, the motor 6 is located on the circumferential surface inside the tank body 1 and three stirring rods 602 are fixedly connected at equal distances. The outer wall of the tank body 1 is fixedly connected to the insulation layer 2.

[0025] In this embodiment, a discharge pipe 104 is fixedly connected to one side of the bottom of the tank body 1 , and a valve 105 is fixedly connected to the discharge pipe 104 .

[0026] In this embodiment, a pressure relief valve 103 is provided on one side of the top of the tank body 1. The pressure relief valve 103 can prevent the internal pressure of the tank body 1 from being too high. A temperature detector 4 is fixedly installed on the other side of the top of the tank body 1, and the probe of the temperature detector 4 is located inside the tank body 1. The temperature detector 4 can detect the internal temperature of the tank body 1, and then control the amount of steam entering in real time.

[0027] In this embodiment, the top of the tank body 1 is further fixedly connected to a first feeding pipe 101 and a second feeding pipe 102 , and the bottom of the tank body 1 is fixedly connected to a supporting leg 3 .

[0028] Working principle: When in use, connect the air inlet pipe 5 with the steam pipe, add bottom water, titanium liquid and crystal seeds into the tank body 1 through the first feed pipe 101 and the second feed pipe 102, and seal the top of the first feed pipe 101 and the second feed pipe 102 through the cover, turn on the motor 6 and the control valve 501, and stir the rotating rod 601 to make the raw materials evenly mixed. The steam enters the tank body 1 through the air inlet pipe 5, the air guide cylinder 11, the L-shaped conduit 7 and the air outlet pipe 701, so that the titanium liquid at all heights can be in contact with the high temperature to achieve uniform heating. At the same time, when the rotating rod 601 rotates with the rotating rod 601, the rotating rod 601 drives the turntable 9 When the arc-shaped notch 901 is engaged with a block 801, the air guide tube 11 and the three L-shaped tubes 7 will rotate along the edge of the tank body 1. When the block 801 rotates half a circle, since the driven disk 8 and the turntable 9 are not coaxial, the block 801 will gradually move away from the arc-shaped notch 901. At this time, the L-shaped tube 7 will no longer rotate. When the turntable 9 continues to rotate, the arc-shaped notch 901 will contact another block 801, and so on. When the motor 6 rotates, the L-shaped tube 7 performs intermittent deceleration motion, so that the titanium liquid at any position inside the tank body 1 can be in contact with the high-temperature steam, achieving more uniform heating and improving the efficiency of hydrolysis.
