[0002] Titanium dioxide, chemically known as TiO2, is a white pigment that requires extremely high fineness and purity. Any coarse particles or impurities will severely affect its product quality and application performance. Therefore, efficient and precise screening is a crucial step in the production process.

[0003] Currently, most screening devices used in titanium dioxide production are vibrating screens. These screens are driven by a vibrating motor to vibrate the screen chamber at high speed, and the screens in the chamber can then screen the titanium dioxide material. However, in actual use, there are some functional deficiencies and room for improvement. For example, in current titanium dioxide screening workshops, it is necessary to manually pour the powder into the screen using beakers or other containers. Dust disperses in the screening workshop, which can easily harm the health of workers. The screens also lack the function of automatic feeding to reduce dust dispersion.

[0004] Now, a novel screening device for titanium dioxide production is proposed to solve the above problems. Utility Model Content

[0026] The vertical center lines of the sieve 5 and the sealing cover 12 coincide. The powder pump 15 and the powder outlet 20 are connected by a pipe. The inclined guide plate 18 is symmetrically distributed about the vertical center line of the powder silo 17. The tops of the powder silo 17 and the inclined guide plate 18 are flush. The arc baffle 16 is flush with the left side of the powder silo 17.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the entire bag of powder is placed on the powder hopper 17, and a slit is cut at the bottom of the powder bag. Under the guidance of two sets of inclined guide plates 18, the powder falls into the powder hopper 17 along the trough 19. Under the suction of the powder pump 15, the powder enters the powder pump 15 along the powder outlet 20 and enters the sieve hopper 5 along the powder inlet pipe 14. The sealing cover 12 can prevent dust from escaping. The vibrating motor 11 drives the sieve hopper 5 to vibrate at high frequency.

[0029] Specifically, such as Figure 3 , Figure 4 and Figure 5 As shown, the electric cylinder 21 drives the push plate 22 to make a reciprocating motion, and the cutter 23 cuts open the bottom of the powder bag, allowing the titanium dioxide to flow out, without the need for manual opening of the bag.

[0030] A thermoelectric cooler 24 is fixedly connected to the middle of the bottom of the bottom protective cover 9.

The PLC controller 2, the thermoelectric cooler 24, the first fan 26 and the second fan 28 are electrically connected to help dissipate heat from the motor.

[0031] Specifically, such as Figure 1 and Figure 2As shown, after the semiconductor cooling chip 24 is powered on, the top is the low-temperature surface and the bottom is the heating surface. The first metal heat sink 25, which is on the low-temperature surface, has a lower temperature. The first fan 26 blows the hot air inside the bottom protective cover 9 towards the low-temperature first metal heat sink 25. Through heat exchange, the air temperature inside the bottom protective cover 9 is reduced, and the inside of the bottom protective cover 9 is in a low-temperature state, which can delay the overheating of the vibration motor 11. The second fan 28 continuously blows air to the high-temperature second metal heat sink 27 to dissipate heat and reduce its temperature.

[0032] Working principle: When using this utility model, firstly, the entire bag of powder is placed on the powder hopper 17. As the powder bag is placed on the powder hopper 17, the inclined guide plate 18 supports the bottom of the powder bag. The electric cylinder 21 drives the push plate 22 to make a reciprocating motion. The cutter 23 cuts open the bottom of the powder bag, allowing the titanium dioxide to flow out. There is no need for manual opening of the bag. The powder is guided by the two sets of inclined guide plates 18 and flows into the powder hopper 17 along the trough 19. Under the suction of the powder pump 15, the powder enters the powder pump 15 along the powder outlet 20 and enters the sieve hopper 5 along the powder inlet pipe 14. The sealing cover 12 can prevent dust from escaping. The vibrating motor 11 drives the sieve hopper 5 to vibrate at high frequency. Under the sieving of the screen 6, the fine powder is discharged from the fine powder outlet 8 and the coarse particles are discharged from the coarse particle outlet 7. The entire operation requires little manual intervention and the dust is basically not dispersed. When the semiconductor cooling chip 24 is powered on, the top is the low-temperature surface and the bottom is the heating surface. The first metal heat sink 25, which is on the low-temperature surface, has a lower temperature. The first fan 26 blows the hot air inside the bottom protective cover 9 toward the low-temperature first metal heat sink 25. Through heat exchange, the air temperature inside the bottom protective cover 9 is reduced. The bottom protective cover 9 is in a low-temperature state, which can delay the overheating of the vibration motor 11. The second fan 28 continuously blows air to the high-temperature second metal heat sink 27 to dissipate heat and reduce its temperature.
