[0006] The effect achieved by the above components is as follows: When processing titanium dioxide, the workers first send the hydrolyzed titanium dioxide material into the tank through the feed pipe. At this time, hot air is sent into the tank through the heating pipe. The hot air heats the material inside the tank. Then, the hot air inside the tank enters the arc plate in the auxiliary device and heats the area around the tank, making use of waste heat and improving resource utilization.
[0007] Preferably, the heating device further includes a hollow box, which is fixedly connected to the upper surface of the cover plate. One end of the heating main tube is fixedly connected to the hollow box. A motor is fixedly connected to the upper surface of the hollow box.

[0008] The effect achieved by the above components is as follows: When heating the material inside the tank, the operator first turns on the motor, which drives the stirring rod and stirring plate to rotate. Then, the operator sends hot air into the hollow box through the heating main pipe. The hot air enters the stirring rod through the reserved hole on the stirring rod, and finally, the hot air enters the tank through the round hole on the stirring plate. The one-way valve on the stirring plate prevents the material from entering the stirring plate through the round hole. By rotating the stirring plate inside the tank and letting the hot air flow out through the round hole of the stirring plate, the material inside the tank is simultaneously stirred and heated, resulting in a better heating effect for the material inside the tank.

[0012] The effect achieved by the above components is that during the rotation of the stirring rod, the stirring rod rotates along with the fan blades, and the fan blades push the material at the bottom of the tank to the top, thereby improving the stirring effect of the material inside the tank.
[0013] Preferably, the arc surface of the heating main tube is fitted with a fixing ring, wherein the fixing ring is fixedly connected to the cover plate by means of a support rod.
[0014] The effect achieved by the above components is that the stability of the heating main tube is improved by setting the fixing ring, and the heating main tube is prevented from shaking.
[0015] Preferably, the auxiliary device further includes a fixing tube, one end of which is fixedly connected to the cover plate and the other end of which is fixedly connected to the arc plate, the arc plate having a cavity inside.
[0016] The effect achieved by the above components is as follows: when there is a lot of hot air inside the tank, the hot air inside the tank enters the cavity of the arc plate through the fixed pipe. The hot air in the cavity heats the surrounding area of the tank, improving the utilization rate of the waste heat of the hot air. Through the auxiliary device, the effect of utilizing the hot air flowing out of the tank is achieved, thus improving the utilization rate of the waste heat of the hot air.
[0017] Preferably, a pressure relief pipe is fixedly connected to one side of the arc plate, a spring is fixedly connected inside the pressure relief pipe, and a piston is fixedly connected to one end of the spring, wherein the piston slides and adapts to the inside of the pressure relief pipe, and a pressure relief hole is opened on the arc surface of the pressure relief pipe.
[0018] The effect achieved by the above components is as follows: when there is a lot of hot air in the cavity inside the arc plate, the hot air squeezes the piston, and the piston moves away from the arc plate. The pressure relief hole on the pressure relief pipe is exposed, and the hot air flows out through the pressure relief hole. When there is less hot air in the cavity of the arc plate, the piston moves back to its original position under the action of the spring return force.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] When heating the material inside the tank, the operator first turns on the motor, which drives the stirring rod and stirring plate to rotate.

During the processing of titanium dioxide, the worker first feeds the hydrolyzed titanium dioxide material into the tank 1 through the feed pipe 3. At this time, hot air is sent into the tank 1 through the heating main pipe 55. The hot air heats the material inside the tank 1. Then, the hot air inside the tank 1 enters the arc plate 62 in the auxiliary device 6 and heats the area around the tank 1, utilizing waste heat and improving resource utilization.
[0029] Reference Figure 1-6 As shown, the heating device 5 also includes a hollow box 51, which is fixedly connected to the upper surface of the cover plate 2. One end of the heating main pipe 55 is fixedly connected to the hollow box 51. A motor 52 is fixedly connected to the upper surface of the hollow box 51. A hollow stirring rod 53 is fixedly connected to the output end of the motor 52. One end of the stirring rod 53 passes through the hollow box 51 and the cover plate 2 and is located inside the tank 1. Several reserved holes 56 are opened on the arc surface of the stirring rod 53 inside the hollow box 51. Several hollow stirring plates 54 are fixedly connected to the arc surface of the stirring rod 53 inside the tank 1. The stirring plates 54 and the stirring rod 53 are interconnected. A circular hole 57 is opened on the surface of the stirring plate 54. A one-way valve is provided at the circular hole 57 of the stirring plate 54. When heating the material inside the tank 1, the operator first turns on the motor 52, which drives the stirring rod 53 and the stirring plate 54 to rotate. Then, the operator sends hot air into the hollow box 51 through the heating main pipe 55. The hot air enters the stirring rod 53 through the reserved hole 56 on the stirring rod 53. Finally, the hot air enters the tank 1 through the round hole 57 on the stirring plate 54. The one-way valve on the stirring plate 54 prevents the material from entering the stirring plate 54 through the round hole 57. By rotating the stirring plate 54 inside the tank 1 and letting the hot air flow out through the round hole 57 of the stirring plate 54, the material inside the tank 1 is simultaneously stirred and heated, resulting in a better heating effect for the material inside the tank 1.
[0030] Reference Figure 1-6As shown, a guide tube 59 is fixedly connected to the inside of the tank 1 by a bracket, and the guide tube 59 is fitted onto the arc surface of the stirring rod 53. The guide tube 59 improves the rotation effect of the stirring rod 53 and prevents it from shaking. A fan blade 58 is fixedly connected to one end of the stirring rod 53 inside the tank 1. During the rotation of the stirring rod 53, the stirring rod 53 drives the fan blade 58 to rotate, and the fan blade 58 pushes the material at the bottom of the tank 1 to the top, improving the stirring effect of the material inside the tank 1. A fixing ring 510 is fitted onto the arc surface of the heating main pipe 55, and the fixing ring 510 is fixedly connected to the cover plate 2 by a support rod.

One end of the fixing pipe 61 is fixedly connected to the cover plate 2, and the other end is fixedly connected to the arc plate 62. The arc plate 62 has a cavity 63 inside. When there is a lot of hot air inside the tank 1, the hot air inside the tank 1 enters the cavity 63 of the arc plate 62 through the fixing pipe 61. The hot air in the cavity 63 heats the surrounding area of the tank 1, improving the utilization rate of the waste heat. The auxiliary device 6 achieves the effect of utilizing the hot air flowing out of the tank 1, thus improving the utilization rate of the waste heat.

The piston 66 slides within the pressure relief pipe 64, and a pressure relief hole 67 is provided on the arc surface of the pressure relief pipe 64. When there is a large amount of hot air in the cavity 63 inside the arc plate 62, the hot air compresses the piston 66, causing the piston 66 to move away from the arc plate 62. The pressure relief hole 67 on the pressure relief pipe 64 is exposed, and the hot air flows out through the pressure relief hole 67. When there is less hot air in the cavity 63 of the arc plate 62, the piston 66 moves back to its original position under the action of the restoring force of the spring 65.
[0033] Working principle: When processing titanium dioxide, the operator first feeds the hydrolyzed titanium dioxide material into the tank 1 through the feed pipe 3. To heat the material inside the tank 1, the operator first turns on the motor 52. The motor 52 rotates the stirring rod 53 and the stirring plate 54. The fan blades 58 at the bottom of the stirring rod 53 push the liquid at the bottom of the tank 1 to the top, improving the stirring effect of the material inside the tank 1. Then, the operator sends hot air into the hollow box 51 through the heating main pipe 55. The hot air passes through the pre-drilled hole 5 on the stirring rod 53. 6. The material enters the interior of the stirring rod 53. Finally, the hot air enters the interior of the tank 1 through the round hole 57 on the stirring plate 54. The one-way valve on the stirring plate 54 prevents the material from entering the interior of the stirring plate 54 through the round hole 57. After the titanium dioxide in the tank 1 is hydrolyzed, it is sent out of the tank 1 through the discharge pipe 4. The stirring plate 54 in the heating device 5 rotates inside the tank 1 and the hot air flows out through the round hole 57 of the stirring plate 54, achieving the effect of stirring and heating the material inside the tank 1 at the same time, making the heating effect of the material inside the tank 1 better.
[0034] When there is a lot of hot air inside the tank 1, the hot air inside the tank 1 enters the cavity 63 of the arc plate 62 through the fixed pipe 61. The hot air in the cavity 63 heats the surrounding area of the tank 1, improving the utilization rate of the waste heat. When there is a lot of hot air in the cavity 63 inside the arc plate 62, the hot air squeezes the piston 66, and the piston 66 moves away from the arc plate 62. The pressure relief hole 67 on the pressure relief pipe 64 is exposed, and the hot air flows out through the pressure relief hole 67. When there is less hot air in the cavity 63 of the arc plate 62, under the action of the return force of the spring 65, the piston 66 moves back to its original position. Through the auxiliary device 6, the effect of utilizing the hot air flowing out of the tank 1 is achieved, improving the utilization rate of the waste heat.
