Description

Technical Field

[0001] This utility model relates to the field of titanium dioxide wastewater treatment technology, and in particular to a titanium dioxide wastewater processor. Background Technology

[0002] Titanium dioxide, also known as titanium white, is an important inorganic chemical pigment. Its main component is titanium dioxide, a white solid and powdery amphoteric oxide. There are two main production processes for titanium dioxide: the sulfuric acid process and the chloride process. The sulfuric acid process involves reacting ilmenite with concentrated sulfuric acid to produce titanium oxysulfate, which is then hydrolyzed in hot water to obtain titanium dioxide hydrate. This hydrate is then calcined, ground, and surface-treated to obtain titanium dioxide. The chloride process uses titanium-containing raw materials, such as rutile ore and titanium-rich slag, which are ground and then reacted with chlorine to produce titanium tetrachloride. This is purified by distillation, followed by gas-phase oxidation, rapid cooling, gas-solid separation, washing, and pulverization to obtain titanium dioxide.

[0003] The production of titanium dioxide generates wastewater containing various harmful substances, commonly referred to as titanium dioxide wastewater. This wastewater primarily originates from the acidolysis process during production, where titanium concentrate and slag react with sulfuric acid to produce acidic wastewater containing sulfate, heavy metal ions, and organic matter. Simultaneously, the acidolysis solution undergoes hydrolysis to generate metatitanic acid, which also produces acidic wastewater. Furthermore, the hydrolyzed metatitanic acid requires washing to remove residual acid and impurities, resulting in neutral washing wastewater. Existing titanium dioxide wastewater treatment systems typically employ a process of neutralization followed by impurity precipitation, ultrafiltration membrane filtration, and finally, pressurized removal of inorganic salts. While this approach achieves compliance with standards and boasts a high water recovery rate, the membrane equipment is highly susceptible to scaling, which even scale inhibitors cannot effectively mitigate. This significantly increases maintenance costs, leading to higher treatment costs and reduced practicality. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a titanium dioxide wastewater treatment device, which aims to improve the existing titanium dioxide wastewater treatment device, whose membrane equipment is prone to scaling, and even the use of scale inhibitors cannot effectively alleviate the problem, but instead greatly increases the operation and maintenance costs, leading to increased treatment costs.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a titanium dioxide wastewater treatment device, comprising a base plate, a sludge treatment tank fixedly connected to the top of the base plate, a blower connected to the right side of the inner wall of the sludge treatment tank, a fixed filter cylinder fixedly connected to the inner wall of the sludge treatment tank near the edge, a rotating filter barrel rotatably connected to the bottom of the inner wall of the sludge treatment tank, a drive shaft fixedly connected to the bottom end of the rotating filter barrel, a bevel gear one fixedly connected to the outer wall of the drive shaft, an asynchronous motor fixedly connected to the top of the base plate near the edge, a bevel gear two fixedly connected to the output end of the asynchronous motor, the outer wall of the bevel gear two meshing with the outer wall of the bevel gear one, a second water pump connected to the top of the fixed filter cylinder, a nitrification filter tank connected to the left end of the second water pump, multiple filter plates fixedly connected to the inner wall of the nitrification filter tank, a drain pipe connected to the bottom of the inner wall of the nitrification filter tank, and a cleaning mechanism connected to the front end of the drain pipe, the cleaning mechanism being used for cleaning devices.

[0006] Through the above technical solutions: the drain pipe discharges the purified water from the equipment; the cleaning mechanism can automatically clean the internal components of the equipment, remove impurities attached to the surface, ensure the continuous and stable operation of the equipment, and extend the service life of the equipment; the filter plate adopts a combination of activated carbon and fiber filter material to adsorb and filter harmful substances in the sewage, remove pollutants such as nitrogen and phosphorus from the sewage, and achieve deep purification of sewage; the fixed filter cartridge can effectively intercept large particulate impurities and suspended solids in the sewage.

[0007] As a further description of the above technical solution:

[0008] The cleaning mechanism includes a clean water tank, the rear of which is connected to the front end of a drain pipe. A first water pump is connected to the right side of the clean water tank, and a connecting pipe is connected to the top of the first water pump. A liquid tank is provided in the middle of the inner wall of the sludge treatment tank. A rotating ring is rotatably connected to the inner wall of the liquid tank, and multiple inclined nozzles are connected to the inner wall of the rotating ring.

[0009] Through the above technical solution: the liquid tank can store the liquid transported into it by the connecting pipe, and pressurize it by the continuous inflow of liquid, so as to spray it out from the tilted nozzle. The first water pump can draw the liquid in the first water pump, thereby driving the entire cleaning mechanism to operate.

[0010] As a further description of the above technical solution:

[0011] The top of the water tank is threaded with a sealing plug, and the outer wall of the sealing plug is fixedly connected with a second anti-slip sleeve.

[0012] Through the above technical solution, the second anti-slip sleeve can increase the friction of the outer wall of the sealing plug, making it more convenient for users to use.

[0013] As a further description of the above technical solution:

[0014] A bracket is fixedly connected to the top front side of the base plate, and a valve is connected to the inner wall of the drain pipe.

[0015] The above technical solution involves using a valve to control the opening and closing of the drain pipe.

[0016] As a further description of the above technical solution:

[0017] A controller is fixedly connected to the top of the bracket, and the controller is electrically connected to the second water pump, the connecting pipe and the asynchronous motor.

[0018] The above technical solution involves using a bracket to install and support the controller.

[0019] As a further description of the above technical solution:

[0021] Through the above technical solution, the nameplate can display relevant information about the device to the user.

[0022] As a further description of the above technical solution:

[0023] Both the sludge treatment tank and the nitrification filter tank are slidably connected to a top cover, and the left end of the second water pump is connected to the inner wall of the nitrification filter tank.

[0024] The above technical solution is used to protect the top of the sludge treatment tank and the nitrification filter tank, preventing dust from entering from the top and causing pollution.

[0025] As a further description of the above technical solution:

[0026] A handle is fixedly connected to the outer wall of the top cover, and a first anti-slip sleeve is fixedly connected to the outer wall of the handle.

[0027] The above technical solution uses a handle to help users open the top cover.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, wastewater is injected into the space between the inner wall of the sludge treatment tank and the outer wall of the rotating filter barrel. Then, it is digested by microorganisms. Subsequently, the asynchronous motor is started to drive the second bevel gear to rotate, which in turn drives the first bevel gear to rotate. This allows the transmission shaft to drive the rotating filter barrel to rotate along the outer wall of the fixed filter barrel, so that the digested liquid enters the fixed filter barrel. The second water pump is started to extract the liquid in the fixed filter barrel and put it into the nitrification filter tank, where it is filtered by the filter plate. This achieves the purpose of treating wastewater with low operation and maintenance costs, improves practicality, and reduces treatment costs.

[0030] 2. In this utility model, by starting the first water pump, the treated liquid in the clean water tank is introduced into the liquid tank through the connecting pipe. Then, due to water pressure, it is sprayed out from the inclined nozzle. While cleaning the surface, the inclined spray will drive the rotating ring to rotate in the liquid tank, thereby achieving the purpose of uniform cleaning of the entire device, improving practicality and speeding up maintenance efficiency.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Please see the appendix Figure 1 - Appendix Figure 3 This utility model provides an embodiment of a titanium dioxide wastewater treatment device, comprising a base plate 1, a sludge treatment tank 11 fixedly connected to the top of the base plate 1, a blower 7 connected to the right side of the inner wall of the sludge treatment tank 11, the sludge treatment tank 11 being used to dissolve pollutants therein, a fixed filter cartridge 8 fixedly connected to the inner wall of the sludge treatment tank 11 near the edge, a rotating filter barrel 6 rotatably connected to the bottom of the inner wall of the sludge treatment tank 11, a drive shaft 10 fixedly connected to the bottom end of the rotating filter barrel 6, the rotating filter barrel 6 being able to adjust the overlap between its filter holes and those of the fixed filter cartridge 8 by rotation, a bevel gear 9 fixedly connected to the outer wall of the drive shaft 10, and an asynchronous motor 13 fixedly connected to the top of the base plate 1 near the edge. The asynchronous motor 13 provides power to the entire structure. The output end of the asynchronous motor 13 is fixedly connected to the bevel gear 12. The outer wall of the bevel gear 12 meshes with the outer wall of the bevel gear 9. The bevel gear 9 can transmit the rotation of the bevel gear 12 through meshing. The top of the fixed filter cylinder 8 is connected to the second water pump 4. The left end of the second water pump 4 is connected to the nitrification filter tank 3. Multiple filter plates 14 are fixedly connected to the inner wall of the nitrification filter tank 3. The second water pump 4 can extract the liquid that has been digested. The bottom of the inner wall of the nitrification filter tank 3 is connected to the drain pipe 24. The front end of the drain pipe 24 is connected to the cleaning mechanism 2. The cleaning mechanism 2 is used for cleaning the device. The drain pipe 24 is used to discharge the liquid that has been processed.

[0040] Specifically, the sludge treatment tank 11 has a cylindrical structure and the tank body is made of corrosion-resistant stainless steel, which can not only effectively resist the chemical corrosion of sewage and extend the service life of the equipment, but also ensure the safety of the treatment process. The blower 7 is a high-efficiency and energy-saving type, which can continuously deliver high-pressure air into the tank to provide sufficient oxygen for subsequent sludge treatment and promote the oxidation and decomposition of organic matter in the sludge. The outer wall of the second bevel gear 12 meshes with the outer wall of the first bevel gear 9. Through this gear transmission method, the rotational power of the asynchronous motor 13 can drive the rotating filter barrel 6 to rotate.

[0041] Please see the appendix Figure 2 - Appendix Figure 4The cleaning mechanism 2 includes a clean water tank 201. The rear side of the clean water tank 201 is connected to the front end of the drain pipe 24. The clean water tank 201 is used to store the treated liquid. The right side of the clean water tank 201 is connected to a first water pump 202. The top of the first water pump 202 is connected to a connecting pipe 203. A liquid tank 206 is opened in the middle of the inner wall of the sludge treatment tank 11. The first water pump 202 is used to draw liquid from the clean water tank 201 for cleaning. A rotating ring 205 is rotatably connected to the inner wall of the liquid tank 206. Multiple inclined nozzles 204 are connected to the inner wall of the rotating ring 205. The inclined nozzles 204 are used to spray the liquid in the liquid tank 206 out by water pressure.

[0042] Specifically, during the cleaning process, the tilting nozzle 204 can spray the cleaning fluid at a specific angle onto the inner wall of the sludge treatment tank 11 to clean the equipment components without dead angles. At the same time, the special tilting angle can apply a thrust to the rotating ring 205, thereby driving it to rotate along the inner wall of the liquid tank 206. The drain pipe 24 allows the water purified by the processor to flow directly into the clean water tank 201, realizing the recycling of water resources and greatly saving the cost of cleaning water.

[0043] Please see the appendix Figure 3 - Appendix Figure 5 A bracket 21 is fixedly connected to the top front side of the base plate 1. A valve 23 is connected to the inner wall of the drain pipe 24. The valve 23 can adjust the rate at which the drain pipe 24 discharges liquid. A sealing plug 22 is threadedly connected to the top of the water tank 201. A second anti-slip sleeve 16 is fixedly connected to the outer wall of the sealing plug 22. The sealing plug 22 can prevent external dust from entering the water tank 201. A controller 20 is fixedly connected to the top of the bracket 21. The controller 20 is electrically connected to the second water pump 4, the connecting pipe 203 and the asynchronous motor 13 respectively. The bracket 21 is used to support and install the controller 20.

[0044] Specifically, the second anti-slip sleeve 16 greatly increases the friction between the operator's hand and the sealing plug 22, making it easy for staff to unscrew or tighten the sealing plug 22 when maintaining and repairing the water tank 201. The sealing plug 22 can fit tightly against the opening of the water tank 201, effectively preventing external dust and impurities from entering the interior of the water tank 201 and ensuring the purity of the cleaning water. The valve 23 can adjust the rate at which the liquid is discharged from the drain pipe 24 according to actual production needs, achieving precise control of the equipment's water output and ensuring the stable operation of the entire sewage treatment system.

[0045] Please see the appendix Figure 2 - Appendix Figure 4A nameplate 18 is fixedly connected to the outer wall of the sludge treatment tank 11, and a screw 19 is fixedly connected to the outer wall of the nameplate 18. The screw 19 is used to fix the nameplate 18. A handle 17 is fixedly connected to the outer wall of the top cover 5, and a first anti-slip sleeve 15 is fixedly connected to the outer wall of the handle 17. The first anti-slip sleeve 15 can increase the friction of the outer wall of the handle 17. The tops of the sludge treatment tank 11 and the nitrification filter tank 3 are slidably connected to the tops of both. The left end of the second water pump 4 is connected to the inner wall of the nitrification filter tank 3. The top cover 5 can protect the tops of the sludge treatment tank 11 and the nitrification filter tank 3.

[0046] Specifically, the first anti-slip sleeve 15 increases the friction between the hand and the handle 17, effectively preventing operational errors caused by hand slippage, and also reducing operator fatigue. The screw 19 can fix the nameplate 18 in the required position, making it convenient for users to quickly observe the nameplate 18 and learn about the relevant information of the device.

[0047] Working principle: Before wastewater treatment, the asynchronous motor 13 is started to drive the bevel gear 12 to rotate, which in turn drives the transmission shaft 10 to rotate through the bevel gear 9, causing the rotating filter 6 to rotate. The angle of the filter holes between the rotating filter 6 and the fixed filter cylinder 8 is adjusted to ensure that the rotating filter 6 and the fixed filter cylinder 8 are not connected at this time. Then, the wastewater is poured into the space between the outer wall of the rotating filter 6 and the inner wall of the sludge treatment tank 11 for microbial digestion. After the initial purification is completed, the asynchronous motor 13 is started to drive the bevel gear 12 to rotate, which in turn drives the bevel gear 9 to rotate, so that the transmission shaft 10 can drive the rotating filter 6 to rotate, so that the filter holes of the rotating filter 6 and the fixed filter cylinder 8 are aligned. Then, the filtered liquid enters the fixed filter cylinder 8. The second water pump 4 is started to draw the liquid into the nitrification filter tank 3. Through the filter material filled between the filter plates 14, the nitrogen element is converted into nitrogen gas and released, so that the nitrogen content in the wastewater is effectively reduced.

[0048] After filtration is completed in the sludge treatment tank 11, the first water pump 202 is started to draw liquid from the clean water tank 201 and into the connecting pipe 203, which then enters the liquid tank 206 and fills it. The liquid is then sprayed out from the inclined nozzle 204 to clean the sludge treatment tank 11. Since the inclined nozzle 204 is at an angle and the rotating ring 205 can rotate in the liquid tank 206, the high-pressure liquid sprayed from the inclined nozzle 204 pushes the rotating ring 205 to rotate along the liquid tank 206, thereby performing multi-angle cleaning.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
