Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a wastewater treatment device for a thermal power plant. Background Art

[0002] As global energy demand increases, thermal power plants have become one of the main energy supply methods in many countries. However, the wastewater generated during thermal power generation has a serious impact on the environment and human health. Therefore, thermal power plant wastewater treatment technology has become the key to solving this problem. By adding precipitants and flocculants to the wastewater, the wastewater is separated and precipitated, and the precipitate and wastewater are treated in batches respectively.

[0003] For example, a wastewater treatment device for a thermal power plant with announcement number CN116813054B includes a liquid storage mechanism, a stirring barrel, a sewage pipe fixedly connected to the bottom end of the stirring barrel, and a liquid inlet pipe fixedly connected to the outside of the stirring barrel, a feeding component is arranged on the outside of the stirring barrel, an opening and closing component is arranged inside the stirring barrel, and a supporting component is adapted to be installed on the outside of the stirring barrel; when adding chemical agents, the equipment can not only discharge two chemical agents in sections and control the amount, but also evenly add the chemical agents to the wastewater to ensure the uniformity of the two groups of chemical agents added to the wastewater, and cooperate with two groups of mixing rods that are staggered and reciprocatingly slide to fully stir the wastewater and the chemical agents, further improving the mixing effect of the wastewater and the chemical agents, and the reciprocatingly sliding piston can further improve the uniformity of the chemical agents sprayed through the spraying pipe.

[0004] When using traditional wastewater treatment devices, the wastewater is first put in, and then all the reagents are injected at once. The feeding is irregular, and the reagents and wastewater do not react completely, which not only easily causes some wastewater to be ineffective, but also leads to waste of reagents. In addition, the position of the reagent placement is fixed, and the reagent cannot be distributed in various areas inside the treatment device, which is also one of the reasons why the reagents cannot fully take effect, affecting work efficiency.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The upper cylinder is divided into two areas by a partition, which are used to store wastewater and chemicals respectively. When the first feed cylinder rotates to be connected with the discharge port, the materials in the corresponding area can automatically fall into the wastewater treatment cylinder. Through the cooperation between the first feed cylinder and the discharge port, wastewater and chemicals can be discharged in equal amounts at the same time. Every time the first feed cylinder rotates, wastewater and chemicals will be fed once, and the amount of wastewater will increase slowly, which is convenient for putting the chemicals into various areas inside the device, and the mixing efficiency is high. The device has a simple structure and is easy to use. It integrates feeding, batching and processing, which greatly improves work efficiency.

[0018] 2. After the wastewater is mixed and precipitated by the reagent, the sludge falls to the lower end of the limit plate through the filter port. The wastewater will also be discharged upward through the filter port due to the precipitation of the sludge. In the process of mixing the wastewater with the reagent, it is also difficult to affect the sludge at the bottom of the limit plate, ensuring that the separated sludge has a certain stability. During the rotation of the connecting ring body, it also contacts the mixing rod, which can drive the mixing rod and the mixing fins to rotate, further increasing the mixing effect of the wastewater and the reagent, and further improving the mixing efficiency.

[0019] 3. After the motor is turned on, the gear, the outer gear ring, and the connecting ring body can rotate, providing a driving force for the device. The device is only provided with one driving force, which can be triggered only when the wastewater treatment cylinder and the upper cylinder are closed, and has a certain degree of safety. When the upper cylinder is placed on the upper end of the support column, the bottom of the upper cylinder compresses the second bellows and the first elastic member downward, ensuring the tightness between the second bellows and the upper cylinder, reducing the leakage of wastewater from the connection, and further increasing the safety of material discharge.

[0020] 4. When the second feed barrel rotates, the sliding block slides along the slide groove of the wave ring body. With the cooperation of the two, the position and height of the discharge port are different each time. Especially the discharge of the agent not only floats on the water surface, but also can be discharged into the wastewater, which further increases the mixing rate of the agent and the wastewater. As the agent sinks, the complete effect of the agent and the wastewater is guaranteed to a great extent, the work efficiency is greatly improved, and it is prevented that the agent is put in one place and the effect with the wastewater is not complete.

[0021] 5. With the rotation of the second feed barrel, the scraper rotates along the filter port, which is convenient for expelling the sediment suspended at the bottom of the limit plate into the filter port, so as to play the role of scraping. Under the action of the second elastic member, the scraper is always pressed on the limit plate, so that the sediment can be scraped and passed through the filter port, and the use effect is good.

Wastewater and agents are respectively put into the wastewater treatment cylinder 11 through the two feed ports 24.

[0028] A supporting mechanism 3 is disposed inside the processing mechanism 1 . The supporting mechanism 3 includes a first clamping plate 31 overlapped and installed on the upper end of the upper cylinder 21 .

[0030] The upper end of the wastewater treatment cylinder 11 is sequentially installed with a first clamping plate 31 and an upper cylinder 21, dividing the wastewater treatment cylinder 11 into three layers. The upper cylinder 21 at the upper end is divided into two areas by a partition 23. The two areas are connected to the wastewater treatment cylinder 11 through two feed ports 24 and a first feed cylinder 43 respectively. The two first feed cylinders 43 are rotatably connected with the first clamping plate 31 and the wastewater treatment cylinder 11 through a connecting ring body 41. When the connecting ring body 41 rotates, the connected mounting ring body 42, the first feed cylinder 43, The first bellows 45 and the second feed barrel 46 rotate together. When the first feed barrel 43 rotates to be connected with the discharge port 47, the materials in the corresponding area can automatically fall into the first feed barrel 43, the first bellows 45 and the second feed barrel 46, and finally are fed into the wastewater treatment barrel 11 through the discharge port 47. The wastewater is mixed with the reagent, and the water and impurities in the wastewater can be separated. The rotation of the first feed barrel 43, the first bellows 45 and the second feed barrel 46 improves the wastewater treatment efficiency and facilitates use.

The size of the discharge port 47 can be opened according to the discharge ratio and discharge speed of wastewater and medicine, so as to ensure that the wastewater and medicine are discharged in equal proportion.

[0032] Through the cooperation between the first feed barrel 43 and the discharge port 47, wastewater and chemicals can be discharged at the same time in equal amounts, and in small amounts and multiple times. Every time the first feed barrel 43 rotates, wastewater and chemicals are fed once, the amount of wastewater increases slowly, and the mixing efficiency is high. The device has a simple structure and is easy to use. It integrates feeding, batching, and processing, and greatly improves work efficiency.

[0033] Example 2: Please refer to Figure 2-Figure 6A support leg 12 is fixedly installed at the lower end of the outer periphery of the wastewater treatment cylinder 11 to support the wastewater treatment cylinder 11. A sewage outlet 13 is opened at the lower end of the wastewater treatment cylinder 11. A valve is provided on the sewage outlet 13. After the valve is opened, the sludge settled at the bottom of the wastewater treatment cylinder 11 can be discharged from here.

[0034] A limiting plate 14 is provided at the lower end of the wastewater treatment cylinder 11, and a plurality of equally spaced filter ports 15 are provided on the limiting plate 14. The filter ports 15 have the lowest slope on the limiting plate 14. After the wastewater is mixed and precipitated by the reagent, the sludge accumulates at the lowest point on the limiting plate 14 and falls to the lower end of the limiting plate 14 along with the filter ports 15. The wastewater will also be discharged upward through the filter ports 15 due to the precipitation of the sludge. The limiting plate 14 is provided at the lower end of the second feed cylinder 46. During the mixing process of the wastewater with the reagent, it is difficult to affect the sludge at the bottom of the limiting plate 14, thereby ensuring that the separated sludge has a certain stability.

[0035] A support rod 16 is fixedly installed on the upper end of the middle part of the limiting plate 14, and a second clamping plate 17 is fixedly installed on the upper end of the supporting rod 16. The second clamping plate 17 and the first clamping plate 31 are arranged on the same horizontal line, and a support column 18 is fixedly installed on the upper end of the second clamping plate 17. The supporting mechanism 3 also includes a limiting ring 32 fixedly installed on the lower end of the first clamping plate 31, and the limiting ring 32 is adapted to the inner wall of the wastewater treatment cylinder 11. A mounting hole 33 is provided in the middle part of the first clamping plate 31. Two connecting ring bodies 41 are clamped on the first clamping plate 31 and the second clamping plate 17 to ensure the stability of the connecting ring body 41. The upper cylinder 21 is arranged at the upper end of the supporting column 18 to ensure the stability and support of the upper cylinder 21 and the wastewater and medicine at its upper end.

[0036] A mixing rod 34 is rotatably mounted on the lower end of the first clamping plate 31, and a mixing fin 35 is fixedly mounted on the outer periphery of the mixing rod 34. The mixing rod 34 is arranged on one side of the connecting ring body 41. The connecting ring body 41 is in contact with the mixing rod 34 during rotation, which can drive the mixing rod 34 and the mixing fin 35 to rotate, further increasing the mixing effect of the wastewater and the reagent, and further improving the mixing efficiency.

[0037] Example 3: Please refer to Figure 2-Figure 6A motor 25 is fixedly installed at the lower end of the upper cylinder 21, and a gear 26 is installed at the output end of the motor 25. An outer gear ring 44 is fixedly installed on the inner wall of the connecting ring body 41. The upper cylinder 21 is installed at the upper end of the wastewater treatment cylinder 11, and the outer gear ring 44 is meshed with the gear 26. After the motor 25 is turned on, the gear 26, the outer gear ring 44, and the connecting ring body 41 can rotate, so the first feed cylinder 43, the first bellows 45, the second feed cylinder 46, and the mixing rod 34 can rotate in the wastewater treatment cylinder 11, providing a driving force for the device. The device is only provided with one driving force, which can only be triggered when the wastewater treatment cylinder 11 and the upper cylinder 21 are closed, and has a certain safety. The wastewater treatment cylinder 11 is started in a closed environment and has good stability.

[0038] The upper end of the first feed cylinder 43 is connected to a second bellows 48 which is rotatably mounted on the bottom of the upper cylinder 21 . The upper end of the connecting ring body 41 is fixedly mounted with a first elastic member 49 which is arranged on the outer periphery of the second bellows 48 .

[0039] When the upper cylinder 21 is placed on the upper end of the support column 18, the bottom of the upper cylinder 21 compresses the second bellows 48 and the first elastic member 49 downward, ensuring the tightness between the second bellows 48 and the upper cylinder 21, reducing the leakage of waste water from the connection, and further increasing the safety of material unloading.

[0040] Example 4: Please refer to Figure 2-Figure 8 A limiting mechanism 5 is arranged inside the processing mechanism 1, and the limiting mechanism 5 includes a wave ring body 51 arranged on the inner wall of the wastewater treatment cylinder 11. The wave ring body 51 has different upper and lower heights. A slide groove 52 is opened on the wave ring body 51, and a sliding block 53 is slidably installed in the slide groove 52. A connecting rod 54 is fixedly installed at one end of the sliding block 53, and a rotating ring body 55 is fixedly installed at one end of the connecting rod 54. The rotating ring body 55 is rotatably connected to the second feeding cylinder 46 and will not move up and down.

[0041] During the rotation of the second feed barrel 46, the rotating ring body 55, the connecting rod 54, and the sliding block 53 are pulled to rotate, and the sliding block 53 slides along the slide groove 52 of the wave ring body 51. With the cooperation of the two, the second feed barrel 46 will reciprocate up and down during the rotation, and the first corrugated tube 45 will adaptively expand and contract. Therefore, the position and height of the discharge port 47 are different each time the material is discharged, especially the discharge of the medicine, which not only floats on the water surface but also can be discharged into the wastewater, further increasing the mixing rate of the medicine and the wastewater, and greatly improving the work efficiency.

[0042] A support block 56 is fixedly installed at the lower end of the wave ring body 51, and a suspended ring body 57 is fixedly installed at the lower end of the support block 56. The suspended ring body 57 is light and can be suspended on the water surface. The suspended ring body 57, the support block 56 and the wave ring body 51 rise with the increase of the wastewater level. Each time the agent is discharged, it will only be placed on the water surface and shallow water. As the agent sinks, the complete effect of the agent on the wastewater is guaranteed to a great extent, preventing the agent from being placed in one place and causing incomplete effect on the wastewater.

[0043] An extrusion mechanism 6 is arranged inside the processing mechanism 1, and the extrusion mechanism 6 includes a sliding rod 61 slidably installed inside the second feed barrel 46, and a scraper 62 is fixedly installed at the lower end of the sliding rod 61. The center of the scraper 62 is coaxially arranged with the center of the filter port 15, and a second elastic member 63 is installed between the scraper 62 and the second feed barrel 46, and the second elastic member 63 is arranged on the outer periphery of the sliding rod 61.

[0044] As the second feed cylinder 46 rotates, the scraper 62 rotates along the filter port 15, so as to expel the sediment suspended at the bottom of the limiting plate 14 into the filter port 15, so as to play the role of scraping. Under the action of the second elastic member 63, the scraper 62 is always pressed on the limiting plate 14, so as to continuously scrape the sediment and clear it through the filter port 15, and the use effect is good.
