Description

[0002] Solar thermal sewage treatment device is an innovative environmental protection equipment. It cleverly uses solar energy, a clean energy, to treat sewage by converting solar energy into heat energy through the principle of photothermal conversion. This device is usually equipped with a special collector that can efficiently absorb solar radiation and heat up the sewage. Under appropriate temperature conditions, it accelerates the decomposition and precipitation of harmful substances in sewage or chemical reactions that are conducive to purification. It can not only effectively reduce the content of pollutants in sewage, including organic matter, pathogens, etc., but also has the advantages of low operating costs and pollution-free emissions, providing a sustainable development solution for sewage treatment, especially suitable for areas with abundant sunshine resources.

DETAILED DESCRIPTION

[0035] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0036] Example 1, using Figure 1-Figure 13 A solar thermal sewage treatment device according to one embodiment of the present invention is described as follows.

[0037] like Figure 1-Figure 2 As shown, a solar thermal sewage treatment device of the present invention comprises a main body box 1, a sewage tank 2 is arranged on the main body box 1, supporting feet 3 are evenly arranged on the bottom of the main body box 1, an extraction unit 4 is fixedly connected to the outer surface of the main body box 1, a cover unit 5 is fixedly connected to the top of the main body box 1, and a solar thermal unit 6 is fixedly connected to the inner wall of the main body box 1;

[0038] When the present invention is working, the sewage is first poured into the sewage tank 2, and then the solar thermal unit 6 absorbs the heat energy in the sunlight and evaporates the sewage. Then the cover unit 5 condenses and collects the evaporated water vapor. Finally, the extraction unit 4 collects the stains generated after the sewage treatment and treats them centrally.

[0039] like Figure 11-Figure 12 As shown, the solar thermal unit 6 includes a liquid storage box 61, the top of the liquid storage box 61 is fixedly connected to a solar thermal collector 62, the bottom of the solar thermal collector 62 is evenly provided with heat conducting rods 63, the bottom of the liquid storage box 61 is fixedly connected to a bent pipe 64, the outer surface of the bent pipe 64 is slidably connected to an outer pipe 65, one end of the outer pipe 65 away from the bent pipe 64 is fixedly connected to a partition 67, a side of the partition 67 close to the outer pipe 65 is symmetrically provided with a telescopic rod 66, one end of the telescopic rod 66 is fixedly connected to the inner wall of the main box 1, the side of the partition 67 away from the telescopic rod 66 is fixedly connected to an evaporation tube 69, and the outer surface of the partition 67 is fixedly connected to a cleaning mechanism 68;

[0040] After the sewage to be purified is poured into the sewage tank 2, the solar energy collector plate will start to work and absorb the heat energy in the sunlight and transfer it to the heat-conducting rod 63 and heat the heat-conducting liquid in the liquid storage tank 61. The evaporation point of the heat-conducting liquid is very high, so it can maintain a very high temperature. The heat-conducting liquid will enter the evaporation tube 69 through the curved pipe 64 and the outer pipe 65, thereby making the temperature of the evaporation tube 69 also very high. After that, the telescopic rod 66 will push the partition 67 and the evaporation tube 69 to move a certain distance, so that the evaporation tube 69 is in the center of the sewage tank 2, which is convenient for the evaporation tube 69 to evaporate the sewage.

[0041] like Fig.13 As shown, the cleaning mechanism 68 includes a support column 681, an end of the support column 681 away from the partition 67 is fixedly connected to a circular ring 682, an outer surface of the circular ring 682 is slidably connected to a sliding block 683, an end of the sliding block 683 close to the evaporating tube 69 is fixedly connected to a second circular rod 686, an end of the second circular rod 686 away from the sliding block 683 is fixedly connected to a scratch plate 687, an end of the sliding block 683 away from the second circular rod 686 is fixedly connected to a first circular rod 684, and an end of the first circular rod 684 away from the sliding block 683 is fixedly connected to a fluid plate 685.

[0042] When the sewage is evaporated in the evaporation tube 69, the sewage at the evaporation tube 69 will be evaporated first, but the stains in the water after evaporation will adhere to the evaporation tube 69, forming a stain layer on the outer wall of the evaporation tube 69. This stain layer will hinder the direct contact between the evaporation tube 69 and the sewage, so that the sewage cannot reach the evaporation temperature. When the water at the bottom of the evaporation tube 69 evaporates, bubbles will be generated. The buoyancy generated by the bubbles floating up will push the fluid plate 685, and then the sliding block 683 will rotate along the ring 682 and drive the scratch plate 687 to scratch the outer wall of the evaporation tube 69, so as to scrape off the attached stains and prevent them from adhering to the evaporation tube 69.

[0043] The bottom of the liquid storage box 61 is fixedly connected to the top of the main box 1 , and one end of the support column 681 is fixedly connected to the outer surface of the partition 67 .

[0044] The specific workflow is as follows:

[0045] During operation, after the sewage to be purified is poured into the sewage tank 2, the solar energy collector plate will start to work and absorb the heat energy in the sunlight and transfer it to the heat conducting rod 63 and heat the heat conducting liquid in the liquid storage box 61. The heat conducting liquid will enter the evaporation tube 69 through the curved tube 64 and the outer tube 65, thereby making the temperature of the evaporation tube 69 also very high. Then the telescopic rod 66 will push the partition 67 and the evaporation tube 69 to move a distance so that the evaporation tube 69 is at the center of the sewage tank 2. The high-temperature evaporation tube 69 will evaporate the water in the sewage. When the evaporation tube 69 evaporates the sewage, the sewage at the evaporation tube 69 will evaporate first, but after the evaporation occurs, the stains in the water will adhere to the evaporation tube 69. When the water at the bottom of the evaporation tube 69 evaporates, bubbles will be generated. The buoyancy generated by the bubbles floating up will push the fluid plate 685, thereby causing the sliding block 683 to rotate along the ring 682 and drive the scratch plate 687 to scratch the outer wall of the evaporation tube 69.

[0046] Example 2, using Figure 1-Figure 13 A solar thermal sewage treatment device according to one embodiment of the present invention is described as follows.

[0047] like Figure 3As shown, a solar thermal sewage treatment device of the present invention is based on the first embodiment, and the extraction unit 4 includes a support plate 41, and the support plates 41 are symmetrically arranged at both ends of the main box 1, and the bottom of one of the support plates 41 is fixedly connected to a servo motor 42, and the output end of the servo motor 42 is fixedly connected to a screw rod 43, and the top of the screw rod 43 is rotatably connected to a top plate 44, and the end of the top plate 44 away from the screw rod 43 is fixedly connected to a guide rod 45, and the bottom of the guide rod 45 is fixedly connected to the top of another support plate 41, and the outer surface of the screw rod 43 is threadedly connected to a movable plate 46, and the outer surface of the movable plate 46 is fixedly connected to a dirt containing mechanism 48, and the outer surface of the top plate 44 is fixedly connected to a support rod 47, and the bottom of the support rod 47 is fixedly connected to a limiting plate 49.

[0048] After the evaporation is completed, the servo motor 42 drives the screw 43 to rotate, thereby moving the moving plate 46, the support rod 47 and the entire dirt holding mechanism 48 upward.

[0049] like Figure 4-Figure 6 As shown, the dirt containing mechanism 48 includes a support rod 481, the bottom of the support rod 481 is fixedly connected to a support plate 482, the outer surface of the support plate 482 is rotatably connected to a rotating shaft 483, the end of the rotating shaft 483 away from the support plate 482 is fixedly connected to a dust accumulation plate 484, both sides of the dust accumulation plate 484 are symmetrically provided with slide grooves 485, the inner wall of the slide groove 485 is slidably connected to a sliding block 683, the bottom of the sliding block 683 is evenly provided with a brush 489, the top of the sliding block 683 is fixedly connected to a scratching knife 4810, the top of the dust accumulation plate 484 is fixedly connected to a side plate 486, and the top of the side plate 486 is provided with a slot 487.

[0050] After moving a certain distance, one side of the cover unit 5 and the dust accumulation plate 484 will be supported by the limiting plate 49, so that the rotating shaft 483 and the dust accumulation plate 484 will rotate. After rotating to a certain angle, the gravity of the sliding plate 488 will cause the sliding plate 488 to move downward along the slide groove 485 and cause the brush 489 to scrape the stains on the water accumulation plate out of the water accumulation plate.

[0051] The outer surface of the support plate 1 41 is fixedly connected to both sides of the main box 1 , and one end of the support rod 2 481 is fixedly connected to the top of the moving plate 46 .

[0052] like Figure 7-Figure 8 As shown, the cover unit 5 includes a top cover 51, the outer surface of the top cover 51 is fixedly connected to a card plate 52, the bottom of the card plate 52 is clamped with a locking pad 53, the inner wall of the top cover 51 is provided with a water storage tank 56, the top of the top cover 51 is fixedly connected to a condensation mechanism 54, the end of the top cover 51 away from the card plate 52 is fixedly connected to a water outlet mechanism 55, and the bottom of the top cover 51 is fixedly connected to a locking column 57.

[0053] As the bubbles generated by the evaporation of sewage at the bottom will drive the stains to fly in the sewage tank 2, some of the stains will float on the surface of the sewage. In order to prevent the stains from floating out of the device due to the bursting of bubbles, a top cover 51 is set to block the stains, and the stains will stick to the bottom of the top cover 51. In the process of the dust accumulation plate 484 moving upward, the positioning column 57 will enter the slot 487 on the side plate 486. Subsequently, the movement of the sliding plate 488 will also drive the scratching knife 4810 to scrape out the stains at the bottom of the top plate 44, and the stains will be processed centrally. At the same time, a water storage tank 56 is set on the top plate 44. After the water vapor evaporates, it will come into contact with the condensation mechanism 54 and condense into clean water and store it in the water storage tank 56. As the water storage tank 56 is subsequently tilted, the clean water will flow out through the water outlet mechanism 55, thereby realizing the treatment of sewage.

[0054] The locking column 57 cooperates with the locking groove 487 , and the bottom of the locking pad 53 is fixedly connected to the top of the main box 1 .

[0055] like Fig. 9 As shown, the condensation mechanism 54 includes a condensation tube 541 , a heat dissipation tube 542 is fixedly connected to the top of the condensation tube 541 , a liquid extraction device 544 is fixedly connected to one end of the heat dissipation tube 542 , and a cold gel body 543 is sleeved on the top of the heat dissipation tube 542 .

[0056] Condensate is stored in the condenser tube 541. When water vapor with a relatively high temperature comes into contact with the condenser tube 541, it will condense into liquid. However, as the condensation continues, the temperature of the condensate will also increase, making the subsequent condensation effect worse. The liquid extraction device 544 will regularly extract the condensate into the heat dissipation tube 542. The cold gel body 543 on the outer wall of the heat dissipation tube 542 will cool the condensate to reduce the temperature of the condensate.

[0057] like Fig.10 As shown, the water outlet mechanism 55 includes a water outlet pipe 551, the inner wall of the water outlet pipe 551 is fixedly connected with a telescopic spring 552, one end of the telescopic spring 552 is fixedly connected with a circular ring plate 553, the inner wall of the circular ring plate 553 is fixedly connected with a support rod three 554, the end of the support rod three 554 away from the circular ring plate 553 is fixedly connected with a thin column 555, and the end of the thin column 555 away from the circular ring plate 553 is fixedly connected with a thick column 556.

[0058] After the top cover 51 is beveled at a certain angle, the gravity of the thick column 556 and the thin column 555 will compress the telescopic spring 552, and the annular plate 553 will move downward along the water outlet pipe 551, so that the thick column 556 cannot block the outflow of water, and the treated water will flow out of the water outlet pipe 551.

[0059] The outer surface of the condenser 541 is fixedly connected to the top of the top cover 51 , the outer surface of the water outlet pipe 551 is fixedly connected to one end of the top cover 51 away from the clamping plate 52 , and the outer surface of the annular plate 553 is slidably connected to the inner wall of the water outlet pipe 551 .

[0060] The specific workflow is as follows:

[0061] During operation, the servo motor 42 will drive the screw rod 43 to rotate, thereby causing the movable plate 46, the support rod 47 and the overall dirt holding mechanism 48 to move upward, so that the dust accumulation plate 484 is engaged with the cover unit 5, and then one side of the cover unit 5 and the dust accumulation plate 484 will be supported by the limit plate 49, so that the rotating shaft 483 and the dust accumulation plate 484 rotate. After rotating to a certain angle, the gravity of the sliding plate 488 will cause the sliding plate 488 to move downward along the slide groove 485 and cause the brush 489 to scrape the stains on the water accumulation plate out of the water accumulation plate. At the same time, the movement of the sliding plate 488 will also drive the scraping knife 4810 to scrape out the stains at the bottom of the top plate 44. The stains will be processed collectively. After the water vapor evaporates, it will come into contact with the condensation mechanism 54 and condense into clean water and store it in the water storage tank 56. As the water storage tank 56 is subsequently tilted, the clean water will flow out through the water outlet mechanism 55, thereby realizing the treatment of sewage.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention.
