Description

Technical Field

[0001] This invention relates to the field of wastewater treatment, specifically to a thermal power wastewater treatment device. Background Technology

[0002] While generating electricity from thermal power plants, they also use steam turbines to drive the flow of heated water vapor to provide heating for residents. During the operation of thermal power plants, a large amount of wastewater is generated. This wastewater contains many harmful substances and needs to be treated before it can be discharged.

[0003] The wastewater from thermal power plants contains harmful substances that make it acidic or alkaline. During the wastewater treatment process, it is necessary to add chemicals to stabilize the pH value at around 7. The chemicals react with the substances in the wastewater to produce solids. These solids are then filtered and precipitated to completely separate them from the water, thus completing the wastewater treatment process, as illustrated by a thermal power plant wastewater treatment device with publication number CN115159721A.

[0004] In existing technologies for treating wastewater by settling, the wastewater is first discharged into a container. The wastewater will only settle down and begin the settling process once it has completely entered or filled the container. If there is a large amount of wastewater and the discharge time is long, the entire settling process will be prolonged, thus reducing the efficiency of the settling. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a thermal power wastewater treatment device that automatically initiates a sedimentation process during wastewater injection, eliminating the need to wait for the wastewater to fully fill the container. This shortens the sedimentation time, improves wastewater treatment efficiency, and effectively solves the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a thermal power wastewater treatment device, comprising a treatment tank and a sedimentation tank disposed on one side of the treatment tank, wherein two second partitions of different heights are fixedly provided on the inner wall of the sedimentation tank, and the second partitions divide the interior of the sedimentation tank into three parts: a first sedimentation chamber, a second sedimentation chamber, and a third sedimentation chamber;

[0007] The settling tank is equipped with a discharge assembly at the top. The discharge assembly includes a central pipe and a float plate at the bottom of the central pipe. Multiple second hoses are fixedly provided at the bottom end of the central pipe. A hollow connector is fixedly provided at one end of each second hose. The hollow connector is fixedly provided at the top of the float plate. In the initial state, the float plate is located inside the first settling chamber.

[0008] The central tube is equipped with two insert tubes. One end of each insert tube is movably connected to the inner wall of the central tube through a sealed bearing, and the other end of each insert tube extends to the outside of the central tube and is fixedly provided with a vertical plate.

[0009] The sedimentation tank is fixedly provided with moving channels on both sides. The moving channels are provided with a base plate inside. The bottom end of the base plate is fixedly provided with a plurality of ball bearings that are in contact with the bottom end of the moving channel. The bottom ends of the two upright plates extend into the two moving channels respectively and are fixedly connected to the top of the corresponding base plates.

[0010] Furthermore, the hollow connector has multiple water outlet holes at its outer end, and a layer of gauze covers the outer surface of the hollow connector. The gauze can obstruct the water flow, thereby reducing the impact force of the water flow.

[0011] One end of one of the tubes passes through the vertical plate and is fitted with a sleeve. The vertical plate and the sleeve are movably connected by a sealed bearing. A first flexible tube is fixed on the sleeve, through which wastewater is transported to the discharge assembly.

[0012] Furthermore, a first partition is fixedly provided on the inner wall of the processing box, which divides the interior of the processing box into a mixing chamber and a filtering chamber. One end of the first hose is fixedly connected to the processing box and communicates with the filtering chamber. A second water pump is fixedly provided on the first hose.

[0013] The mixing chamber is equipped with a transfer water pipe. The top of the transfer water pipe bends toward the first partition and passes through the first partition. A first water pump is fixed on the transfer water pipe to transfer wastewater from the mixing chamber to the filtration chamber.

[0014] Furthermore, a mixing assembly is provided on the top of the mixing chamber. The mixing assembly includes a mounting frame, and linear motors are installed on both sides of the processing box. The two ends of the mounting frame are respectively connected to the moving parts of the two linear motors, and the linear motors drive the mixing assembly to reciprocate inside the mixing chamber.

[0015] Two motors are mounted on the top of the mounting frame. The output shaft of the motor passes through the mounting frame and is fixedly mounted on a stirring shaft. The bottom end of the stirring shaft extends into the mixing chamber. Multiple stirring rods are fixedly mounted on the stirring shaft. The stirring shaft drives the stirring rods to rotate, thereby achieving the stirring effect.

[0016] Furthermore, an extension rod is provided between the two stirring shafts. The extension rod is fixed to the bottom end of the mounting frame, and the bottom end of the extension rod extends into the mixing chamber and is equipped with a pH sensor.

[0017] A controller is mounted on the top of the mounting bracket, and a display screen is mounted on the front of the processing box. The display screen is located at the output end of the controller, and the pH sensor is located at the input end of the controller, so that the specific data of the pH value detection is displayed on the display screen.

[0018] Furthermore, the filter chamber is provided with a filter assembly, the filter assembly including a filter screen, the filter screen being inclinedly arranged inside the filter chamber, and the first hose and the transfer water pipe being located on both sides of the filter assembly;

[0019] The filter screen is fixedly provided with a frame at its outer end, and a rubber pad is fixedly provided at the outer end of the frame. The rubber pad is in contact with the inner wall of the filter chamber, which improves the sealing performance of the filter assembly.

[0020] Furthermore, the filter assembly also includes a fixed shaft located at the top of the processing box, with end blocks mounted on both ends of the fixed shaft via bearings, and the end blocks being fixedly located at the top of the processing box;

[0021] Both ends of the fixed shaft are provided with springs, and the two ends of the springs are fixedly connected to the outer end of the fixed shaft and the end block on the corresponding side, respectively.

[0022] The top of the frame extends to the top of the processing box and is fixedly provided with two connecting plates. The top and bottom of the connecting plates are bolted with clamps, which are fixed to the outer end of the fixed shaft, so that the filter screen can be disassembled and replaced.

[0023] Compared with the prior art, the present invention provides a thermal power wastewater treatment device, which has the following beneficial effects:

[0024] 1. By installing a discharge component at the sedimentation tank and dividing the interior of the sedimentation tank into three independent spaces, when water is injected into the sedimentation tank for sedimentation, once one space is full, the water will automatically flow to the adjacent space, causing the discharge component to move synchronously and inject water into the other space. The space filled with water will then settle and begin sedimentation. In this way, the sedimentation process starts automatically during the injection of wastewater, without waiting for the wastewater to be completely filled, shortening the sedimentation time and improving the efficiency of wastewater treatment.

[0025] 2. A filter assembly is installed inside the filter chamber. Wastewater is injected from one side of the filter assembly and discharged from the other side. During this process, the wastewater passes through the filter assembly for filtration. The filter screen is set at an angle inside the filter chamber, with the side of the filter screen containing impurities facing downwards. Therefore, under the action of gravity, impurities are not easy to adhere to the filter screen, thus avoiding impurities from clogging the filter assembly. Attached Figure Description

[0036] To make the technical means, creative features, and achieved objectives and effects of this invention readily understandable, the invention will be further described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0037] like Figure 1-9As shown, the present invention provides a thermal power wastewater treatment device, including a treatment tank 1 and a sedimentation tank 10 disposed on one side of the treatment tank 1. Two second partitions 9 of different heights are fixedly provided on the inner wall of the sedimentation tank 10. The second partitions 9 divide the interior of the sedimentation tank 10 into three parts: a first sedimentation chamber 1001, a second sedimentation chamber 1002, and a third sedimentation chamber 1003.

[0038] The sedimentation tank 10 is provided with a discharge assembly 8 at the top. The discharge assembly 8 includes a central pipe 801 and a float plate 806 at the bottom of the central pipe 801. A plurality of second hoses 805 are fixedly provided at the bottom end of the central pipe 801. A hollow connector 810 is fixedly provided at one end of each second hose 805. The hollow connector 810 is fixedly provided at the top of the float plate 806. In the initial state, the float plate 806 is located inside the first sedimentation chamber 1001.

[0039] The central tube 801 is provided with two insertion tubes 802. One end of the insertion tube 802 is movably connected to the inner wall of the central tube 801 through a sealed bearing, and the other end of the insertion tube 802 extends to the outside of the central tube 801 and is fixedly provided with a vertical plate 803.

[0040] Both sides of the sedimentation tank 10 are fixedly provided with moving channels 14. The moving channels 14 are provided with a base plate 804. The bottom end of the base plate 804 is fixedly provided with a plurality of ball bearings 808 that are in contact with the bottom end of the moving channels 14. The bottom ends of the two upright plates 803 extend into the two moving channels 14 respectively and are fixedly connected to the top end of the corresponding base plates 804.

[0041] Wastewater requiring sedimentation is fed into the inlet pipe 802, then into the central pipe 801, and subsequently flows downwards along the second flexible hose 805 to the hollow connector 810, where it flows outwards. Since the float plate 806 is initially located in the first sedimentation chamber 1001, the outflowing water enters the first sedimentation chamber 1001, gradually increasing the water level. This causes the float plate 806 to rise. Once the first sedimentation chamber 1001 is full, the water will pass over the second partition 9 and enter the second sedimentation chamber 1002. The float plate 806, floating on the water surface, will also flow into the second sedimentation chamber 1002. The movement of the float plate 806 will pull the central pipe 801... This causes the vertical plate 803 and the bottom plate 804 to move along the moving channel 14. The discharge assembly 8 moves along with the floating plate 806. After the floating plate 806 enters the second sedimentation chamber 1002, it will inject water into the second sedimentation chamber 1002. The water in the first sedimentation chamber 1001 will settle and begin to settle. After the second sedimentation chamber 1002 is full, the floating plate 806 will enter the third sedimentation chamber 1003 in the same way, and then inject water into the third sedimentation chamber 1003. The water in the second sedimentation chamber 1002 will settle and begin to settle. In this way, the sedimentation process starts automatically during the injection of wastewater, without waiting for the wastewater to be completely filled, thereby shortening the sedimentation time and improving the efficiency of wastewater treatment.

[0042] To reduce the impact of water flow on the wastewater inside the first sedimentation chamber 1001, such as Figure 1 , 3 As shown in Figures 8 and 9, the hollow connector 810 has multiple water outlet holes 811 at its outer end. The outer surface of the hollow connector 810 is covered with a layer of gauze 807, which can obstruct the water flow and thus reduce the impact force of the water flow.

[0043] One end of one of the insertion tubes 802 passes through the vertical plate 803 and is fitted with a sleeve 809. The vertical plate 803 and the sleeve 809 are movably connected by a sealed bearing. A first flexible hose 7 is fixedly provided on the sleeve 809, and wastewater is transported to the discharge assembly 8 through the first flexible hose 7.

[0044] A first partition 6 is fixedly provided on the inner wall of the processing box 1. The first partition 6 divides the interior of the processing box 1 into a mixing chamber 4 and a filtering chamber 5. One end of the first hose 7 is fixedly connected to the processing box 1 and communicates with the filtering chamber 5. A second water pump 13 is fixedly provided on the first hose 7.

[0045] The mixing chamber 4 is equipped with a transfer water pipe 15. The top end of the transfer water pipe 15 bends toward the first partition 6 and passes through the first partition 6. A first water pump 11 is fixed on the transfer water pipe 15 to transfer wastewater from the mixing chamber 4 to the filtration chamber 5.

[0046] The wastewater is mixed with the reagent in the mixing chamber 4 and the pH value is adjusted. After the adjustment is completed, the first water pump 11 drives the wastewater in the mixing chamber 4 to flow along the transfer water pipe 15 to the filter chamber 5 for preliminary filtration to remove larger solid impurities. The filtered wastewater flows along the first hose 7 to the sleeve 809 under the drive of the second water pump 13, and then enters the insertion tube 802. The wastewater flowing into the hollow connector 810 flows out through the outlet hole 811. The gauze 807 covers the outside of the hollow connector 810. The flowing water needs to pass through the gauze 807, so the gauze 807 plays a buffering role to avoid the water flow impact being too large and causing the water surface to be difficult to calm.

[0047] Chemicals need to be added to the wastewater to remove harmful substances, such as... Figure 1 , 2 As shown in Figures 3 and 5, a mixing assembly 3 is provided on the top of the mixing chamber 4. The mixing assembly 3 includes a mounting frame 301. Linear motors 2 are installed on both sides of the processing box 1. The two ends of the mounting frame 301 are respectively connected to the moving parts of the two linear motors 2. The linear motors 2 drive the mixing assembly 3 to move back and forth inside the mixing chamber 4.

[0048] Two motors 302 are mounted on the top of the mounting frame 301. The output shaft of the motor 302 passes through the mounting frame 301 and is fixedly mounted on a stirring shaft 303. The bottom end of the stirring shaft 303 extends into the mixing chamber 4. Multiple stirring rods 304 are fixedly mounted on the stirring shaft 303. The stirring shaft 303 drives the stirring rods 304 to rotate, thereby achieving the stirring effect.

[0049] Untreated wastewater is stored inside the mixing chamber 4. At this time, a chemical is added to the wastewater inside the mixing chamber 4. The chemical reacts with the harmful substances in the wastewater to produce solid impurities, thereby removing the harmful substances. During this process, the motor 302 drives the stirring shaft 303 and stirring rod 304 to rotate, which mixes the chemical and wastewater. At the same time, the linear motor 2 drives the mixing assembly 3 to move back and forth inside the mixing chamber 4, thereby effectively stirring the wastewater in all parts of the mixing chamber 4.

[0050] Removing harmful substances also requires adjusting the pH level, such as... Figure 1 , 5 As shown, an extension rod 305 is provided between the two stirring shafts 303. The extension rod 305 is fixedly installed at the bottom of the mounting frame 301. The bottom end of the extension rod 305 extends into the mixing chamber 4 and is equipped with a pH sensor 306.

[0051] A controller 307 is mounted on the top of the mounting bracket 301, and a display screen is mounted on the front of the processing box 1. The display screen is located at the output end of the controller 307, and the pH sensor 306 is located at the input end of the controller 307, so that the specific data of the pH detection is displayed on the display screen.

[0052] While removing harmful substances, the agent also adjusts the pH value of the wastewater. During the process of adding the agent and stirring, the pH sensor 306 is inserted into the wastewater to detect its pH value in real time. The detected data is directly displayed on the screen through the controller 307, which helps to monitor the pH value of the wastewater in real time until the pH value stabilizes at around 7.

[0053] After the reaction, larger solid impurities in the wastewater need to be separated by filtration, such as... Figure 3 , 6 As shown in Figures 7 and 8, the filter chamber 5 is provided with a filter assembly 12, which includes a filter screen 1204. The filter screen 1204 is inclined inside the filter chamber 5. The first hose 7 and the transfer water pipe 15 are located on both sides of the filter assembly 12.

[0054] The filter screen 1204 is fixedly provided with a frame 1205 at its outer end, and a rubber pad 1206 is fixedly provided at the outer end of the frame 1205. The rubber pad 1206 is in contact with the inner wall of the filter chamber 5, which improves the sealing performance of the filter assembly 12.

[0055] After fully reacting with the reagent, the wastewater is transferred to the filter chamber 5. All wastewater entering the filter chamber 5 is eventually discharged through the first hose 7. The filter assembly 12 is located between the transfer pipe 15 and the first hose 7. Therefore, as the wastewater flows to the first hose 7, it will inevitably pass through the filter assembly 12 and be filtered by the filter screen 1204 to separate larger solid impurities in the wastewater. The filter screen 1204 is inclined inside the filter chamber 5, with the side of the filter screen 1204 where the impurities are located facing downwards. Therefore, under the action of gravity, impurities are not easy to adhere to the filter screen 1204, thus avoiding clogging of the filter assembly 12.

[0056] To facilitate the disassembly and replacement of filter 1204, such as Figure 2 , 3 As shown in Figures 6 and 7, the filter assembly 12 also includes a fixed shaft 1201 disposed on the top of the processing box 1. Both ends of the fixed shaft 1201 are equipped with end blocks 1203 via bearings, and the end blocks 1203 are fixedly disposed on the top of the processing box 1.

[0057] Both ends of the fixed shaft 1201 are provided with spring springs 1202, and the two ends of the spring springs 1202 are fixedly connected to the outer end of the fixed shaft 1201 and the end block 1203 on the corresponding side, respectively.

[0058] The top of the frame 1205 extends to the top of the processing box 1 and is fixedly provided with two connecting plates 1207. The top and bottom of the connecting plates 1207 are both bolted with clamps 1208. The clamps 1208 are fixed to the outer end of the fixed shaft 1201, so that the filter screen 1204 can be disassembled and replaced.

[0059] The filter screen 1204 is detachably installed on the outer end of the fixed shaft 1201. In normal use, the spring force of the spring 1202 drives the fixed shaft 1201 and drives the filter screen 1204, so that the rubber pad 1206 is in close contact with the inner wall of the filter chamber 5. If necessary, the filter screen 1204 can be rotated by rotating the fixed shaft 1201 to remove it from the filter chamber 5 and replace it.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
