Description

Technical Field

[0001] This invention relates to the field of wastewater treatment and solar thermal water production technology, and particularly to a solar thermal water production device with wastewater purification function. Background Technology

[0002] Solar thermal water treatment technology utilizes solar energy to heat and evaporate wastewater, then collects the freshwater through condensation. This green water treatment technology is widely used in drinking water supply and industrial wastewater resource recovery in water-scarce areas. However, most existing solar thermal water treatment devices directly feed the wastewater into a solar distiller for evaporation and condensation, which has the following drawbacks: First, impurities such as silt and suspended solids in the wastewater easily adhere to the photothermal evaporation surface of the solar distiller, reducing the photothermal conversion efficiency and making cleaning difficult. Second, the lack of a wastewater preheating process means that ambient temperature wastewater enters the distiller directly, requiring a large amount of solar energy to heat it to its boiling point, resulting in low water production efficiency and high energy consumption per unit of water produced. Third, most of the filter components are fixed structures, requiring shutdown and disassembly for cleaning after clogging by impurities, making continuous operation impossible and severely affecting the working efficiency of the device. Summary of the Invention

[0003] The main objective of this invention is to provide a photothermal water production device with wastewater purification function, which can effectively solve the problems of existing photothermal water production devices lacking efficient filtration and self-cleaning functions, having low water production efficiency due to lack of wastewater preheating, and requiring shutdown for impurity cleaning.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A solar thermal water production device with wastewater purification function includes a support frame and a solar distiller, and further includes a support component and an adjustment component with a top of the support frame for precisely adjusting the tilt angle of the solar distiller, a filtration mechanism for multi-stage filtration of impurities in wastewater, and a transmission component. The filtration mechanism includes a filtration component and a sealing component. The filtration component rotates through the transmission component, the support component, and the adjustment component. When rotating, the filtration component cleans impurities on the surface of the filtration components, and at the same time, when rotating 180 degrees, it discharges impurities from the discharge trough opened at the top of the support frame.

[0005] Preferably, the support assembly includes a mounting frame, a fixing frame, a rotating shaft, and two support frames for supporting and mounting the solar distiller. The solar distiller is fixedly mounted inside the mounting frame. The fixing frame is fixedly connected to the mounting frame and fixedly sleeved on the rotating shaft. The rotating shaft is rotatably connected to the two support frames.

[0006] Preferably, the adjustment assembly includes two electric push rods that operate synchronously via a synchronizer to push the mounting frame, an ejector frame, a fixing rod, and a connecting frame fixedly installed at the bottom of the mounting frame. The ejector frame is fixedly connected to the output ends of the two electric push rods, and the fixing rod is rotatably connected to the ejector frame and the connecting frame.

[0007] Preferably, the support assembly further includes a fixed bend, a pointing arrow, a transmission gear, and an angle scale for real-time monitoring of the rotation angle of the mounting frame and the solar distiller. One end of the horizontal section of the fixed bend is fixedly connected to the pointing arrow, and the bent section is fixedly connected to one of the rotating shafts. The transmission gear and the angle scale are both fixedly sleeved on the rotating shafts. The pointing arrow abuts against the surface of the angle scale, and the pointing direction is directly opposite the angle scale value on the surface of the angle scale.

[0008] Preferably, the adjustment assembly further includes two slide rails and two sliding seats for horizontally limiting the two electric push rods. The slide rails are fixedly installed on the top of the bracket, and two guide rods are fixedly installed on their inner walls. The sliding seats are slidably sleeved on the two guide rods and slidably cooperate with the slide rails. The two electric push rods are respectively fixedly installed on the top of the two sliding seats.

[0009] Preferably, the filter assembly includes a filter tank with fixed water pipes fixed at both ends and a plurality of filter screens fixedly installed on the inner wall of the filter tank and arranged in order of filter specifications. The top of the filter tank is provided with a discharge trough. The two fixed water pipes are used for water inlet and water outlet respectively, and are connected to an external water pump through a rotatable hose. The hose at the water outlet end is connected to the solar distiller through the water pump.

[0010] Preferably, the transmission assembly includes a transmission shaft rotatably connected to the rotating shaft, and synchronous pulleys are fixedly adjusted on the outer wall of both the transmission shaft and the fixed water pipe located at the water outlet end. Synchronous belts are sleeved on the two synchronous pulleys. A driven gear that meshes with the transmission gear is also fixedly sleeved on the outer wall of the transmission shaft. The transmission ratio between the driven gear and the transmission gear is 3:1.

[0011] Preferably, the sealing assembly includes two support seats fixedly installed on the top of the bracket and rotatably connected to the filter tank, and an arc-shaped baffle fixedly installed between the two support seats. The arc-shaped baffle is made of borosilicate tempered glass with high light transmittance and high thermal conductivity, which can transmit sunlight to preheat the wastewater in the filter tank. The opening of the arc-shaped baffle is symmetrically arranged with the discharge chute, and the arc-shaped baffle is sealed to the outer wall of the filter tank by high-temperature resistant sealing cotton.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention, through the cooperation of support and adjustment components, can precisely adjust the tilt angle of the solar distiller to adapt to the solar altitude angle at different times, thereby improving the photothermal absorption efficiency. At the same time, the angle is visualized and accurately monitored through the angle scale and directional arrow, ensuring adjustment accuracy. No additional electronic monitoring equipment is required, and the structure is simple and reliable.

[0013] This invention, by setting up a transmission component linked to the angle adjustment mechanism of the solar still, uses the power of angle adjustment to synchronously drive the filter tank to rotate, realizing automatic scraping of impurities on the filter screen surface and 180-degree rotation for discharge, without the need for machine shutdown and disassembly, effectively improving the continuous operation capability of the device; at the same time, by using multi-stage filter screens arranged in order of increasing filtration precision, it can remove impurities of different particle sizes from wastewater in stages, avoiding contamination of the solar thermal evaporation surface of the solar still and ensuring the photothermal conversion efficiency.

[0014] This invention utilizes an arc-shaped baffle made of high-transmittance and high-thermal-conductivity borosilicate tempered glass. This not only ensures a tight seal between the filter tank and the arc-shaped baffle to prevent wastewater leakage, but also allows sunlight to preheat the wastewater inside the filter tank, increasing the initial temperature of the wastewater before it enters the solar distiller. This reduces the light and heat energy consumption required for distillation and significantly increases the water production per unit time. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-6 As shown, a solar thermal water production device with wastewater purification function includes a support frame 1 and a solar distiller 2. The top of the support frame 1 is provided with a support component 3 and an adjustment component 4. The support component 3 is used to support the solar distiller 2, and the adjustment component 4 is used to drive the support component 3 to rotate to adjust the tilt angle of the solar distiller 2. The top of the support frame 1 is also provided with a filter mechanism 5. The filter mechanism 5 is connected to the support component 3 through a transmission component 6 and can rotate synchronously with the angle adjustment of the solar distiller to achieve self-cleaning and discharge.

[0019] The support assembly 3 includes a mounting frame 301, a fixing frame 302, two support frames 303, and a rotating shaft 304. The solar distiller 2 is fixedly installed inside the mounting frame 301. The fixing frame 302 is fixedly connected to the bottom of the mounting frame 301 and fixedly sleeved in the middle of the rotating shaft 304. The two ends of the rotating shaft 304 are respectively rotatably connected to the two support frames 303. The two support frames 303 are symmetrically fixedly installed on the top of the bracket 1. The support assembly 3 also includes a fixed bend 305, a pointing arrow 306, a transmission gear 307, and an angle scale 308. One end of the horizontal section of the fixed bend 305 is fixedly connected to the pointing arrow 306, and the bent section is fixedly connected to one end of the rotating shaft 304. The transmission gear 307 and the angle scale 308 are both fixedly sleeved on the same end of the rotating shaft 304. The pointing arrow 306 abuts against the surface of the angle scale 308, and the pointing direction is directly opposite the angle scale value on the surface of the angle scale 308. When the rotating shaft 304 rotates, the pointing arrow 306 rotates synchronously with the rotating shaft, and the tilt angle of the solar distiller 2 can be read by the scale value it points to.

[0020] The adjustment assembly 4 includes two slide rails 401, two sliding seats 403, two electric push rods 404, an ejector frame 405, a fixing rod 406, and a connecting frame 407. The two slide rails 401 are symmetrically fixedly installed on the top of the bracket 1. Two parallel guide rods 402 are fixedly installed on the inner wall of each slide rail 401. The sliding seats 403 are slidably sleeved on the two guide rods 402 and slide in cooperation with the inner wall of the slide rail 401. The two electric push rods 404 are respectively fixedly installed on the top of the two sliding seats 403, and the two electric push rods 404 achieve synchronous extension and retraction through a synchronizer. The ejector frame 405 is fixedly connected to the output ends of the two electric push rods 404. The two ends of the fixing rod 406 are rotatably connected to the ejector frame 405 and the connecting frame 407 respectively. The connecting frame 407 is fixedly installed on the bottom of the mounting frame 301. When the electric push rod 404 extends or retracts, it pushes the mounting frame 301 to rotate around the pivot 304 through the ejector frame 405, the fixing rod 406 and the connecting frame 407, thereby adjusting the tilt angle of the solar distiller 2. At the same time, the sliding seat 403 slides along the slide rail 401 to adapt to the horizontal displacement of the electric push rod 404.

[0021] The filtration mechanism 5 includes a filtration assembly and a sealing assembly. The filtration assembly includes a filter tank 501, two fixed water pipes 502, and several filter screens 503. The two fixed water pipes 502 are fixedly installed at both ends of the filter tank 501, serving as the inlet and outlet of water, respectively. Both fixed water pipes 502 are connected to an external water pump via rotatable hoses. The hose at the outlet end is connected to the inlet of the solar distiller 2 via the water pump. Several filter screens 503 are fixedly installed on the inner wall of the filter tank 501 and are arranged sequentially along the water flow direction according to the filtration precision from low to high, enabling graded filtration of impurities such as silt and suspended solids in wastewater. A discharge trough 504 is provided at the top of the filter tank 501 to discharge the impurities intercepted by the filter screens.

[0022] The sealing assembly includes two support seats 505 and an arc-shaped baffle 506. The two support seats 505 are symmetrically fixedly installed on the top of the bracket 1, and the two ends of the filter tank 501 are rotatably connected to the two support seats 505 respectively. The arc-shaped baffle 506 is fixedly installed between the two support seats 505 and is located on the outer side of the lower half of the filter tank 501. The opening of the arc-shaped baffle 506 is symmetrically arranged with the discharge trough 504. The arc-shaped baffle 506 is sealed to the outer wall of the filter tank 501 by high-temperature resistant sealing cotton, which can prevent the wastewater in the filter tank 501 from leaking from the discharge trough 504. The arc-shaped baffle 506 is made of borosilicate tempered glass with high light transmittance and high thermal conductivity. Sunlight can pass through the arc-shaped baffle 506 and shine on the lower half of the outer wall of the filter tank 501, thereby preheating the wastewater to be treated in the filter tank 501.

[0023] The transmission assembly 6 includes a transmission shaft 601, two synchronous pulleys 602, a synchronous belt 603, and a driven gear 604. The transmission shaft 601 is rotatably mounted on one of the support frames 303 and is arranged parallel to the rotating shaft 304. The driven gear 604 is fixedly sleeved on one end of the transmission shaft 601 and meshes with the transmission gear 307. The transmission ratio between the driven gear 604 and the transmission gear 307 is 3:1. The two synchronous pulleys 602 are respectively fixedly sleeved on the other end of the transmission shaft 601 and the outer wall of the fixed water pipe 502 at the water outlet end. The synchronous belt 603 is sleeved on the two synchronous pulleys 602. When the rotating shaft 304 rotates, the drive shaft 601 rotates through the meshing of the drive gear 307 and the driven gear 604. Then, the filter tank 501 rotates through the synchronous pulley 602 and the synchronous belt 603. Since the transmission ratio is 3:1, when the solar distiller 2 rotates 60 degrees, the filter tank 501 rotates 180 degrees. At this time, the discharge chute 504 faces downward and is aligned with the discharge chute 101 at the top of the support 1. The impurities intercepted by the filter screen are discharged from the discharge chute 504 and the discharge chute 101 under the action of gravity.

[0024] Working principle: When the device is in use, the wastewater to be treated enters the filter tank 501 through the fixed water pipe 502 at the inlet end. After being filtered by the multi-stage filter screen 503, it is sent to the solar distiller 2 through the fixed water pipe 502 at the outlet end. During this process, sunlight shines through the curved baffle 506 made of borosilicate tempered glass to irradiate the filter tank 501, preheating the wastewater in the tank, increasing the initial temperature of the wastewater and reducing the energy consumption of subsequent distillation.

[0025] Based on the solar altitude angle at different times, the electric push rod 404 is activated. The extension and retraction of the electric push rod 404 drives the lifting frame 405 to rise and fall. Through the fixed rod 406 and the connecting frame 407, the mounting frame 301 is pushed to rotate around the rotating shaft 304, realizing the precise adjustment of the tilt angle of the solar distiller 2, so that the solar thermal surface of the solar distiller 2 faces the sun and maximizes the solar thermal absorption efficiency. The rotating shaft 304 rotates synchronously and drives the transmission gear 307 to rotate. The transmission gear 307 meshes with the driven gear 604, and the two transmit power at a transmission ratio of 3:1, driving the transmission shaft 601 to rotate at an increased speed. The transmission shaft 601 then transmits power to the fixed water pipe 502 at the water outlet through the meshing of the synchronous pulley 602 and the synchronous belt 603, thereby driving the filter tank 501 to rotate around its own axis, realizing the linkage coupling between the angle adjustment power and the rotation power of the filter tank, without the need for an additional drive source.

[0026] During the rotation of the filter tank 501, the arc-shaped baffle 506 and the high-temperature resistant sealing cotton attached to the outer wall of the filter tank 501 form a scraping action, continuously scraping away impurities attached to the surface of the filter screen 503. Constrained by a 3:1 transmission ratio, for every 60 degrees of rotation of the solar distiller 2, the filter tank 501 rotates 180 degrees accordingly. At this time, the discharge chute 504 on the filter tank 501 is precisely facing downwards and is aligned vertically with the discharge chute 101 at the top of the support 1. The scraped and detached impurities are discharged from the outside of the device in sequence through the discharge chute 504 and the discharge chute 101 under the action of gravity, completing the automatic cleaning of the filter components and the discharge of impurities. The entire process does not require stopping the machine for disassembly, ensuring the continuous and stable operation of the device.

[0027] After preheating, the wastewater enters the solar distiller 2 and evaporates rapidly under the action of solar heat to form water vapor. The water vapor is cooled and liquefied by the condensation structure and then collected to obtain clean fresh water, thus achieving efficient wastewater purification and integrated solar heat water production.
