Description

Technical Field

[0001] This utility model relates to the field of titanium dioxide production technology, and in particular to a device for precisely controlling the concentration of titanium dioxide slurry. Background Technology

[0002] Titanium dioxide, also known as titanium dioxide, is a dye and pigment. The production of titanium dioxide involves a rotary kiln calcination process. After calcination in the rotary kiln, the raw materials produce granular waste, which needs to be pulverized through three stages: roller milling, wet ball milling, and sand milling, before proceeding to the next process.

[0003] After the granular materials from the kiln are initially crushed by a roller mill, the powdered material needs to be pulped with demineralized water for subsequent wet ball milling and sand milling. The purpose of the demineralized water is to adjust the concentration of the pulp. Traditional pulping methods require weighing the powder and demineralized water according to a specific ratio, then pouring them into a mixing device for stirring. After stirring, the pulp is poured out. Then, new powder and demineralized water are weighed for the next pulping operation. However, in a factory's assembly line operation, the powder produced by the roller mill is continuously generated, requiring a large amount of pulp to be prepared. Workers need to periodically start and stop the mixing device, weigh the powder and demineralized water, and pour out the pulp, resulting in low pulping efficiency. Utility Model Content

[0004] In view of the above problems, this utility model provides a device for precisely controlling the concentration of titanium dioxide slurry.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for precisely controlling the concentration of titanium dioxide slurry is provided, comprising a mounting frame, a cylindrical body vertically mounted on the mounting frame, a vertical baffle plate inside the cylindrical body dividing the interior of the cylindrical body into a feeding zone and a discharging zone, a channel forming between the baffle plate and the bottom wall of the cylindrical body, a feeding port at the top of the cylindrical body in the feeding zone, two feed pipes connected to the inner side of the feeding port for supplying powder and demineralized water respectively, a first valve on the demineralized water feed pipe, an overflow port on the side wall of the cylindrical body in the discharging zone, the overflow port being higher than the height of the channel, a stirring roller rotatably mounted inside the cylindrical body, a drive component for driving the stirring roller to rotate on the cylindrical body, and a weighing mechanism for weighing the weight of the cylindrical body on the mounting frame.

[0006] Furthermore, the weighing mechanism includes multiple weighing sensors, and multiple protruding lugs are fixed on the outer wall of the cylinder. The multiple lugs are connected to the mounting frame through each weighing sensor.

[0007] Furthermore, the mounting frame is equipped with multiple limiting blocks, and each limiting block has a limiting groove on the side near the cylinder to accommodate the lugs and the weighing sensor.

[0008] Furthermore, at least two stirring rollers are provided, respectively located in the feeding zone and the discharging zone, with the stirring rollers parallel to the axial direction of the cylinder.

[0009] Furthermore, the stirring roller includes a rotating shaft, a first helical blade, and a second helical blade. The rotating shaft is rotatably disposed inside the cylinder. Both the first and second helical blades are fixed on the outer wall of the rotating shaft, and the second helical blade is located outside the first helical blade. The helical directions of the first and second helical blades are opposite.

[0010] The beneficial effects of this utility model are as follows: The device for precisely controlling the concentration of titanium dioxide slurry can simultaneously feed and discharge the slurry. Through the weighing mechanism and controller, the corresponding first valve can be controlled to adjust the flow rate of demineralized water, thereby dynamically adjusting the concentration of the slurry and maintaining it in a qualified state, which has the effect of improving the slurrying efficiency of titanium dioxide.

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] This application discloses a device for precisely controlling the concentration of titanium dioxide slurry, referring to... Figure 1 , Figure 2 and Figure 3The system includes a mounting frame 1, on which a cylindrical body 2 is vertically mounted. A vertical baffle 3 is welded inside the cylindrical body 2, dividing its interior into a feeding zone 21 and a discharging zone 22. A channel is formed between the baffle 3 and the bottom wall of the cylindrical body 2. A feeding port 23 is located at the top of the cylindrical body 2 in the feeding zone 21. Two feed pipes 6, for supplying powder and demineralized water respectively, are connected to the inner side of the feeding port 23. A first valve 7 is installed on the demineralized water feed pipes 6. An overflow port 24 is located on the side wall of the cylindrical body 2 in the discharging zone 22, and the overflow port 24 is higher than the channel height. A stirring roller 4 is rotatably mounted inside the cylindrical body 2, and a driving component 5 is installed on the cylindrical body 2 to drive the stirring roller 4 to rotate. A weighing mechanism for weighing the cylindrical body 2 is installed on the mounting frame 1.

[0018] In this embodiment, the outlet ends of the two feed pipes 6 are suspended and do not contact the cylinder 2. An external container for collecting the pulping liquid is connected to the overflow port 24, and the overflow port also does not contact the container. Titanium dioxide powder and demineralized water can be injected into the cylinder 2 through the two feed pipes 6, respectively. The volume of the space between the overflow port 24 and the inner bottom wall of the cylinder 2 is fixed. A weighing mechanism can weigh the cylinder 2 itself and the weight of the pulping liquid between the overflow port 24 and the inner bottom wall of the cylinder 2. The weight of the pulping liquid is equal to the fixed volume multiplied by the pulping liquid density. The higher the density of the pulping liquid, the higher the concentration of titanium dioxide.

[0019] When the flow rate of the powder increases, causing an increase in the concentration of the pulp in the feeding zone 21, this can be detected by the weighing mechanism. At this time, increasing the diameter of the first valve 7 can increase the flow rate of the demineralized water, and the stirring roller 4 can be rotated to stir the pulp, so that the concentration of the pulp in the cylinder 2 returns to a qualified state. While the powder and demineralized water are being injected, the pulp in the discharge zone 22 has been stirred evenly and can be discharged through the overflow port 24. The two feed pipes continuously inject powder and demineralized water into the cylinder 2, and the concentration of the pulp can be dynamically adjusted by the weighing mechanism and the first valve to maintain it within a qualified concentration range.

[0020] The weighing mechanism is connected to a controller (which uses a computer control system), and the controller is connected to the first valve 7 on the feed pipe 6 corresponding to the demineralized water. The granular material falling into the kiln varies in shape, and after initial crushing into powder by the roller mill, the flow rate of this powder injected into the feed zone 21 fluctuates. The weighing mechanism can weigh the cylinder 2 and the pulping material in real time. When the weighing mechanism detects that the weight of the pulping material exceeds the threshold for the qualified concentration, the controller can control the first valve 7 to increase its diameter to increase the flow rate of the demineralized water until the pulping material concentration returns to the qualified state. When the weighing mechanism detects that the weight of the pulping material is lower than the threshold for the qualified concentration, the controller can control the first valve 7 to decrease its diameter to decrease the flow rate of the demineralized water until the pulping material concentration returns to the qualified state.

[0021] This application discloses a device for precisely controlling the concentration of titanium dioxide slurry. The device allows for simultaneous feeding and discharging of the slurry. A weighing mechanism and controller work in conjunction with a first valve 7 to adjust the flow rate of demineralized water, thereby dynamically regulating the concentration of the slurry and maintaining it at a suitable level. This eliminates the need for operators to periodically start and stop the stirring device to discharge the slurry, thus improving the efficiency of titanium dioxide slurry production.

[0022] A discharge pipe 25 is welded to the bottom of the cylinder 2, and a second valve is installed on the discharge pipe 25. After the slurrying operation is completed, feeding can be stopped and the second valve can be opened to discharge the remaining slurry in the cylinder 2. Both the first valve and the second valve are electronic valves.

[0023] Specifically, the weighing mechanism includes multiple weighing sensors 8, and multiple protruding lugs 9 are welded and fixed on the outer wall of the cylinder 2. The multiple lugs 9 are connected to the mounting frame 1 through each weighing sensor 8.

[0024] In this embodiment, multiple weighing sensors 8 are mounted on the mounting frame 1, and multiple lugs 9 are connected to the top of each weighing sensor 8, so that the cylinder 2 and the slurry can be weighed.

[0025] Furthermore, multiple limiting blocks 10 are welded onto the mounting frame 1, and each limiting block 10 has a limiting groove 101 on the side near the cylinder 2 for accommodating the lug 9 and the weighing sensor 8.

[0026] In this embodiment, when the stirring roller 4 rotates and pulps, it will cause the cylinder 2 to vibrate. The limiting block 10 can restrict each lug 9 and the weighing sensor 8 within the limiting groove 101, thereby improving the installation stability of the cylinder 2 on the mounting frame 1.

[0027] To improve the pulping effect, at least two mixing rollers 4 are provided, which are respectively located in the feed area 21 and the discharge area 22. The mixing rollers 4 are parallel to the axial direction of the cylinder 2.

[0028] In this embodiment, the driving component 5 includes a driving motor, which is disposed at the bottom of the cylinder 2, and the output shaft of the driving motor is connected to the stirring roller 4 for transmission.

[0029] Reference Figure 4 The stirring roller 4 includes a rotating shaft 41, a first helical blade 42 and a second helical blade 43. The rotating shaft 41 is rotatably disposed inside the cylinder 2. The first helical blade 42 and the second helical blade 43 are both welded to the outer wall of the rotating shaft 41, and the second helical blade 43 is located outside the first helical blade 42. The helical directions of the first helical blade 42 and the second helical blade 43 are opposite.

[0030] In this embodiment of the application, the rotation of the rotating shaft 41 can cause the first spiral blade 42 and the second spiral blade 43 to rotate synchronously in opposite directions, thereby causing the pulping material near the rotating shaft 41 and the pulping liquid near the inner wall of the cylinder 2 to flow in opposite directions in the vertical direction within the feeding zone 21 and the discharge zone 22, further improving the pulping effect of the pulping material.

[0031] The implementation principle of the device for precisely controlling the concentration of titanium dioxide slurry according to this application embodiment is as follows: Slurry can be fed into and discharged simultaneously inside the cylinder 2. A weighing mechanism and controller can work together to control the corresponding first valve 7 to adjust the flow rate of demineralized water, thereby dynamically adjusting the concentration of the slurry and maintaining it at a qualified level. This eliminates the need for operators to periodically start and stop the stirring device to pour out the slurry, thus improving the efficiency of titanium dioxide slurry production.
