DETAILED DESCRIPTION

[0042] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, and not all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the present application.

[0043] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0044] As shown in Figures 1-8 The present application discloses an environment-friendly manure water heating device, which comprises a manure water storage area and a heating assembly. The heating assembly comprises a focusing unit, which comprises a plurality of first lenses 1. A plurality of refraction zones are arranged on the incident surface and / or the exit surface of the first lenses 1, and the refraction zones are arranged towards the optical axis of the first lenses 1, so that the light rays passing through the refraction zones are deflected towards the optical axis of the first lenses 1, and the light rays after refraction through the refraction zones can converge at a point, thereby realizing focusing of sunlight.

[0045] The heat conduction unit comprises a first pipeline 17 in which a heat transfer medium is stored. The heat transfer medium exchanges heat with the manure water in the manure water storage area through a heat exchange area. The exit surface of the first lenses 1 is arranged towards the first pipeline 17, and the distance between the exit surface of the first lenses 1 and the first pipeline 17 is within a first preset range, so that at least part of the exit light spot of the first lenses 1 is located on the first pipeline 17, which means that part of the area or the whole area of the exit light spot formed after focusing through the first lenses 1 can irradiate on the first pipeline 17, thereby heating the heat transfer medium in the first pipeline 17. The heat transfer medium heated to a required temperature transfers heat to the manure water in the manure water storage area through the heat exchange area, thereby heating the manure water. Whether the heat transfer medium is heated to the required temperature can be determined by an operator according to the heating time, or a temperature sensor in communication with the heat transfer medium in the first pipeline 17 is arranged on the first pipeline 17, and the determination is made by a controller connected with the temperature sensor or the operator according to the feedback of the temperature sensor. It can be seen that, from the perspective of long-term use of the environment-friendly manure water heating device for heating manure water (long-term use can be understood as being used for heating manure water before the environment-friendly manure water heating device is retired), compared with the way of heating manure water by using fuel such as oil or gas in the prior art, the present application does not need to spend cost to purchase fuel such as oil or gas after manufacturing the environment-friendly manure water heating device, but directly uses solar energy to heat manure water. In comparison, the cost of heating manure water by the environment-friendly manure water heating device in the present application is lower, and no waste gas formed by fuel reaction is generated during the heating process of manure water, which is more environmentally friendly.

[0046] And, the sum of the light absorption areas of the first pipes 17 is greater than the sum of the projection areas of the light spots of all the first lenses 1 on the first pipes 17, which means that, in the case that the first pipes 17 storing the heat transfer medium and the exposed heat transfer medium have the same area, compared with directly heating the exposed heat transfer medium by sunlight, the first pipes 17 have a larger light absorption and heating area, and have a higher heating efficiency, which reduces the problem that the sunlight heating of the heat transfer medium is slow, the solar elevation angle or azimuth angle changes frequently, and the first lens 1 needs to be adjusted frequently, which consumes more manpower or material resources;

[0047] Meanwhile, compared with the way of directly heating the exposed heat transfer medium by sunlight, the first pipes 17 reduce the emission of the heat transfer medium, reduce the loss of the heat transfer medium due to the emission, reduce the frequency of supplementing the heat transfer medium, and then reduce the cost of supplementing the heat transfer medium. In summary, the present application reduces the cost of heating organic waste such as manure.

[0048] The environment-friendly type in the environment-friendly manure heating device refers to, compared with the way of heating manure by burning fuel or gas, the present application uses solar energy to heat manure, and there is no waste gas generated by burning fuel or gas in the heating process, which pollutes the surrounding environment less, so the manure heating device in the present application is called "environment-friendly manure heating device". Manure can be understood as excrement after water treatment (water treatment refers to adding a certain amount of water to the excrement to reduce the agglomeration of the excrement), or excrement mixed with urine and digestive juice. The excrement can be livestock and poultry excrement or human excrement.

[0049] The manure storage area includes a box or a shell, or other structures capable of storing manure. The structure shape and material forming the manure storage area are not limited and can be determined according to the working condition requirements. The structure forming the manure storage area can be made of concrete, plastic, metal or other materials. Figure 1 、 Figure 2 As shown in the drawings, the manure storage area includes a manure chamber 3, the manure chamber 3 has a cavity for storing manure, and the manure chamber 3 is provided with a switch door capable of closing and opening the manure chamber 3.

[0050] The first lens 1 has a plurality of refractive regions symmetrically arranged on the incident surface and / or the exit surface of the first lens 1 with the optical axis of the first lens 1 as the symmetry axis. The refractive regions are arranged towards the optical axis. The symmetric arrangement of the refractive regions on the first lens 1 allows the light received by different refractive regions to be deflected towards the optical axis of the first lens 1, avoiding the problem of lateral dispersion caused by the asymmetric arrangement of the refractive regions on the first lens 1, which deflects the light towards a direction other than the optical axis of the first lens 1. The curvature of all the refractive regions on the first lens 1 gradually increases from the optical axis of the first lens 1 towards the edge of the first lens 1, and the focal length of all the refractive regions on the first lens 1 is the same. This allows the light refracted by all the refractive regions on the first lens 1 to converge at a point, achieving light focusing, avoiding the problem that the light passing through the refractive regions at the edge of the first lens 1 is far from the focal point, and the light passing through the refractive regions close to the optical axis of the first lens 1 is close to the focal point, resulting in the light passing through different refractive regions on the first lens 1 failing to converge at a point. In short, the first lens 1 can focus sunlight.

[0051] The first lens 1 can be a Fresnel lens, a biconvex lens, or a plano-convex lens, or other lenses with light focusing capability. When the first lens 1 is a Fresnel lens, the incident surface of the first lens 1 is a plane, and the exit surface of the first lens 1 is a surface with a plurality of concentric grooves. The refractive region is located on the exit surface, and the refractive region is the groove on the exit surface at this time. When the first lens 1 is a plano-convex lens, the incident surface of the first lens 1 is a convex surface, and the exit surface of the first lens 1 is a plane. When the first lens 1 is a biconvex lens, the incident surface and the exit surface are both refractive regions. The more specific structure of the above-mentioned Fresnel lens, plano-convex lens and biconvex lens and other details are applicable to the prior art. The distance between the exit surface of the first lens 1 and the first pipe within the first predetermined range means that as long as part of the exit spot of the first lens 1 falls on the first pipe, the distance between the exit surface of the first lens 1 and the first pipe at this time is within the first predetermined range, for example, the distance between the exit surface of the first lens 1 and the first pipe can be exactly the focal length of the first lens 1, or the distance between the exit surface of the first lens 1 and the first pipe is less than or greater than the focal length, but at least part of the exit spot of the first lens 1 is located on the pipe. By replacing different types of first lens 1, adjusting the inclination angle of the first lens 1, and replacing different sizes of the first pipe 17, the exit spot of the first lens 1 can be partially or completely irradiated on the first pipe.

[0052] The heating assembly further comprises a reflecting unit, the reflecting unit comprising a plurality of second lenses 5 corresponding to the first lenses 1, the second lenses 5 being arranged towards the first pipe 17 and the exit surface of the corresponding first lens 1 at the same time, the distance between the exit surface of the first lens 1 and the second lens 5 being within a first preset range, so that the exit light spot of any first lens 1 is located within the entrance surface of at least one second lens 5, which makes the second lens 5 receive all or part of the exit light spot of the first lens 1, and the optical performance parameter of the second lens 5 is within a second preset range, the distance between the reflecting surface of the second lens 5 and the first pipe being within a third preset range, so that at least part of the exit light spot of the second lens 5 is located on the first pipe 17, wherein the optical performance parameter of the second lens 5 includes the reflectivity, surface roughness and other parameters of the second lens 5, so as to ensure that the second lens 5 can reflect the received part or all of the light spot to the first pipe 17 after receiving part or all of the exit light spot of the first lens 1. This means that the second lens 5 reflects the sunlight focused by the first lens 1 to the first pipe 17 to heat the heat transfer medium. In the case of the same type of first lens 1, compared with the case without the second lens 5, after the second lens 5 is arranged, because there is a certain distance between the first lens 1 and the second lens 5, and between the second lens 5 and the first pipe 17, the first lens 1 can be arranged at a space farther away from the first pipe 17, at this time, the space for arranging the first lens 1 is larger, and more first lenses 1 can be arranged to increase the area of sunlight irradiated on the first pipe 17; at the same time, this increases the distance between the first lens 1 and the first pipe 17, and reduces the probability of collision between the first lens 1 and the first pipe 17; moreover, the second lens 5 can correct the light path of the first lens 1 to ensure that the sunlight focused by the first lens 1 can irradiate on the first pipe 17 after being reflected by the second lens 5; and when the second lens 5 adopts a lens that can focus, the second lens 5 can focus the sunlight twice to improve the sunlight intensity irradiated on the first pipe 17, thereby accelerating the heating efficiency of the manure water.

[0053] The distance between the exit surface of the first lens 1 and the second lens 5 (specifically, the distance between the exit surface of the first lens 1 and the entrance surface of the second lens 5) in the first preset range means that the distance between the exit surface of the first lens 1 and the entrance surface of the second lens 5 is equal to the focal length of the first lens 1; or, in the case of ensuring that the exit spot of the first lens 1 falls at least partially on the entrance surface of the second lens 5, the distance between the exit surface of the first lens 1 and the entrance surface of the second lens 5 can be greater than or less than the focal length of the first lens 1. Similarly, the third preset range means that the distance between the second lens 5 and the first pipe 17 (specifically, the distance between the exit surface of the second lens 5 and the first pipe 17) is equal to the focal length of the second lens 5, or, in the case of ensuring that the second lens 5 can reflect the exit spot of the first lens 1 onto the first pipe 17, the distance between the exit surface of the second lens 5 and the first pipe 17 can be greater than or less than the focal length of the second lens 5. The second preset range means that, when the second lens 5 can reflect part or all of the light spot of the first lens 1 onto the first pipe 17, the reflectivity, surface roughness and other parameters of the second lens 5 are within a certain numerical range.

[0054] The second lens 5 can be a spherical mirror or a parabolic mirror, etc. with reflecting ability or both reflecting and condensing ability. The more specific principles of the first lens 1 and the second lens 5 and other details are applicable to the prior art. It should be noted that when the heating assembly only includes a focusing unit, the settings of the first lens 1 such as the height and inclination angle of the first lens 1 (hereinafter, the settings of the first lens 1 and the second lens 5 include spatial position and inclination angle, etc.) need to ensure that the focused sunlight can be irradiated on the first pipe 17; when the heating assembly includes a focusing unit and a reflecting unit, the settings of the first lens 1 need to ensure that the focused sunlight can be irradiated on the second lens 5, and the settings of the second lens 5 need to ensure that the focused sunlight of the first lens 1 can be reflected onto the first pipe 17.

[0055] The heating assembly further includes an adjusting unit, which includes a rack 2, a first fixing member, and a second fixing member 12. The first lens 1 and the second lens 5 are movably arranged on the rack 2. When the first lens 1 is in the first preset posture, i.e. the required working posture, the first fixing member fixes the first lens 1 on the rack 2; when the second lens 5 is in the second preset posture, i.e. the required working posture, the second fixing member fixes the second lens 5 on the rack 2. This allows the first lens 1 and the second lens 5 to be adjusted according to the changes of the solar azimuth angle and the solar elevation angle, so as to reduce the incident angle of the sunlight irradiated on the first lens 1, improve the light absorption efficiency of the first lens 1, and ensure that the focused sunlight of the first lens 1 can be received by the second lens 5.

[0056] The movably setting of the first lens 1 and the second lens 5 on the frame 2 means that the first lens 1 moves and / or rotates on the frame 2 according to the working condition requirement; similarly, the second lens 5 moves and / or rotates on the frame 2 according to the working condition requirement. For example, the first lens 1 and the second lens 5 can be connected with the frame 2 through the metal shaped hose 10, wherein, because the metal shaped hose 10 can be arbitrarily bent and the direction and posture are determined, which makes the operator can realize the adjustment of the position and the inclination angle of the first lens 1 and the second lens 5 by bending the metal shaped hose 10. The metal shaped hose 10 can also be called a gooseneck pipe, and the specific structure and principle are prior art, which will not be described here; it should be noted that according to the size and weight of the first lens 1 and the second lens 5, different diameters and types of metal shaped hoses 10 are selected, so that the posture of the first lens 1 and the second lens 5 can be maintained unchanged without moving the metal shaped hose 10.

[0057] When the first lens 1 is only rotationally connected with the frame 2, one end of the first lens 1 is rotationally connected with the frame 2, and the other end is connected with the piston rod of the cylinder, when the inclination angle of the first lens 1 needs to be adjusted, the cylinder is started, the extension length of the piston rod is adjusted, and then the inclination angle of the first lens 1 is adjusted; or, the cylinder can be omitted, and a support rod capable of being supported on the ground is arranged, the other end of the first lens 1 is supported by the support rod, a telescopic rod can be used, and different lengths of the support rod can be replaced according to different rotation angles of the first lens 1. Or, when the first lens 1 can only move relative to the frame 2, a slide rail arranged in a vertical direction or a horizontal direction is arranged on the frame 2, a sliding block matched with the slide rail is arranged on the first lens 1, and a pin hole matched with the sliding block is arranged on the bottom of the slide rail, when the first lens 1 is fixed, the pin rod is sequentially inserted into the pin holes of the sliding block and the bottom of the slide rail (the axis direction of the pin hole is perpendicular to the sliding direction of the sliding block), which makes the first lens 1 unable to move on the frame 2; when the first lens 1 needs to be moved, the pin rod is extracted, the first lens 1 is moved to the required position along the slide rail, after the first lens 1 is moved to the position, the pin rod is sequentially inserted into the pin holes of the sliding block and the bottom of the slide rail again, and the position of the first lens 1 is fixed. Or, when the first lens 1 needs to be rotatable and movable on the frame 2, the first lens 1 is arranged on a sliding seat matched with a slide on the frame 2, a first end of the first lens 1 is rotationally connected with the sliding seat, the sliding seat and the bottom of the slide are also provided with pin holes (the axis direction of the pin hole is perpendicular to the sliding direction of the sliding seat), when the first lens 1 is fixed, the pin shaft is sequentially inserted into the pin holes of the sliding seat and the bottom of the slide, and the position of the first lens 1 is fixed, when the first lens 1 needs to be moved on the frame 2, the pin rod is extracted, after the first lens 1 is moved to the position, the pin rod is inserted into the sliding seat and the bottom of the slide again, and the first lens 1 is fixed; and the sliding seat is also provided with a linear driving device such as a cylinder or a hydraulic cylinder, an output end of the linear driving device is connected with a second end of the first lens 1, the linear driving device is started, the extension length of the output end of the linear driving device is controlled, and the inclination angle of the first lens 1 can be adjusted. Or, according to the working condition requirement, other structures can also be used to realize the rotation and / or movement of the first lens 1 on the frame 2.

[0058] When only the first lens 1 exists, the inclination angle of the first lens 1 is the inclination angle of the first lens 1 relative to the first pipe 17; when both the first lens 1 and the second lens 5 exist, the inclination angle of the first lens 1 is the inclination angle of the first lens 1 relative to the second lens 5, and the inclination angle of the second lens 5 is the inclination angle of the second lens 5 relative to the first pipe 17. Similarly, the second lens 5 can also adopt the arrangement mode of the first lens 1 described above, which will not be described here. It should be noted that the rotation connection and / or sliding first fixing member 14 and second fixing member 12 of the first lens 1 mentioned above include the pin rod described above. When the first lens 1, the second lens 5 and the rack 2 are connected, in order to avoid damaging the first lens 1 and the second lens 5, a lens frame can be wrapped outside the first lens 1 and the second lens 5, and the rack 2 can be connected with the lens frame outside the first lens 1 or the second lens 5.

[0059] The heat transfer medium can be heat-conducting oil or air or other medium capable of transferring heat. The first pipe 17 is made of copper pipe or other material with good heat conductivity. In order to meet the condition that the sum of the light absorption areas of the first pipe 17 is greater than the sum of the projection areas of the focused exit regions of the first lens 1 on the first pipe 17, the first pipe 17 can adopt a spiral pipe or a U-shaped pipe, or a plurality of protrusions or grooves (the protrusions can be fins or other structures) can be arranged on the surface of the first pipe 17 to increase the light absorption area of the first pipe 17. Alternatively, the first pipe 17 can also have other shapes that meet the condition that the sum of the light absorption areas of the first pipe 17 is greater than the sum of the projection areas of the focused exit regions of the first lens 1 on the first pipe 17.

[0060] The heat exchange zone in the present application has various arrangement forms. When the heat exchange zone includes the second pipe 20 arranged in the fecal water storage zone, the second pipe 20 is in communication with the first pipe 17 and in contact with the fecal water in the fecal water storage zone, the second pipe 20 and the first pipe 17 are connected end to end to form a first circulation loop, and a first conveying member for conveying the heat transfer medium is arranged on the first circulation loop, which can be arranged on the first pipe 17 or the second pipe 20. When the operator determines that the heat transfer medium in the first pipe 17 is heated to the required temperature according to experience or through feedback of the temperature sensor arranged on the first pipe 17, the first conveying member is started to convey the heat transfer medium from the first pipe 17 into the second pipe 20 and contact with the fecal water to heat the fecal water; after the heat exchange is completed, the heat transfer medium is conveyed back to the area of the first pipe 17 outside the fecal water zone for the next heating. At this time, the heat exchange between the fecal water and the heat transfer medium is wall heat exchange, and the heat exchange zone is the pipe wall of the second pipe 20.

[0061] And, the heating assembly further comprises a storage area for storing the heat transfer medium, the storage area, the first pipeline 17 and the second pipeline 20 are connected in series to form a first circulation loop. When the manure water is not heated, the heat transfer medium is stored in the storage area, when the manure water chamber 3 needs to be heated, the first conveying device conveys the heat transfer medium to the first pipeline 17, and after the heat transfer medium is heated to the required temperature, the heat transfer medium is conveyed into the second pipeline 20 to exchange heat with the manure water; after the heat exchange is completed, the heat transfer medium is conveyed into the storage area again. The storage area acts as a "transit station" for the heat transfer medium, which can store the heat transfer medium and play a role in relieving pressure and flow fluctuations.

[0062] Alternatively, the heat exchange area comprises a manure water storage area, and the first pipeline 17 directly communicates with the manure water storage area; wherein the manure water storage area is provided with an inlet and an outlet which both communicate with the manure water storage area and the first pipeline 17, the first pipeline 17 and the manure water storage area are connected in series to form a second circulation loop, and the second circulation loop is provided with a second conveying device for conveying the heat transfer medium, and the second conveying device is arranged on the first pipeline 17; after the heat transfer medium in the first pipeline 17 is heated to the required temperature, the second conveying device is started to directly input the heat transfer medium into the manure water storage area, the manure water and the heat transfer medium directly contact, and then the manure water is heated, at this time, the heat exchange area is the manure water storage area, and the manure water and the heat transfer medium exchange heat in the manure water storage area, after the heat exchange is completed, the heat transfer medium is input into the first pipeline 17 area outside the manure water storage area for next time heating; and a filter screen is arranged at the outlet to intercept solid manure to reduce solid manure backflow with the heat transfer medium, at this time, the heat transfer medium can be gaseous heat transfer medium or liquid heat transfer medium. When the heat transfer medium is gaseous heat transfer medium, the first pipeline 17 can only input the heat transfer medium into the manure water storage area, and the manure water storage area is provided with an exhaust port which communicates with the manure water storage area, and the cooling gas of the gaseous heat transfer medium after heating the manure water can be discharged from the exhaust port.

[0063] Alternatively, the heat exchange area comprises a heating chamber 6, the heating chamber 6 is provided with the first pipeline 17, and the manure water storage area is connected in series with the heating chamber 6 through a third pipeline to form a third circulation loop, and the third pipeline is provided with a third conveying device; at this time, after the heat transfer medium is heated to the required temperature, the third conveying device is started to input the manure water into the heating chamber 6 to exchange heat with the heat transfer medium, and then the manure water is heated, and then the heated manure water is input back to the manure water chamber 3 for next time heat exchange. And, at this time, the environmentally friendly manure water heating device further comprises a cleaning assembly, the cleaning assembly comprises a plurality of nozzles which are arranged towards the first pipeline 17 and communicate with the heating chamber 6, the nozzles are communicated with a storage tank storing cleaning medium such as water or cleaning liquid through a pipeline, the pipeline is provided with a conveying pump, and the heating chamber 6 is provided with a discharge port, after the environmentally friendly manure water heating device operates for a period of time, the conveying pump is started to spray the cleaning medium to the first pipeline 17 to remove the manure material attached to the first pipeline 17.

[0064] Or, the first pipeline 17 is sleeved outside the fecal water storage area, at this time, the first pipeline 17 is connected end to end, the fourth conveying member is arranged on the first pipeline 17, and the heat exchange area is the pipeline wall of the first pipeline 17 and the fecal water storage area; at this time, the fecal water can directly absorb the heat of the heat transfer medium through the pipeline wall of the first pipeline 17 and the fecal water storage area, so that the time for the heat transfer medium to pass through the first pipeline 17 is saved, and the fecal water is heated more efficiently; the fourth conveying member is started when the fecal water is heated, so that the heat transfer medium continuously flows in the first pipeline 17, and the fecal water storage area is uniformly heated; at this time, the total amount of the heat transfer medium in the first pipeline 17 is less than the capacity of the first pipeline 17, so that the heat transfer medium can flow in the first pipeline 17.

[0065] The first conveying member, the second conveying member, the third conveying member and the fourth conveying member can be pumps or other devices capable of conveying the heat transfer medium. A charging port communicating with the first pipeline 17 can be arranged on the first pipeline 17, and a valve is arranged on the charging port. When the heat transfer medium needs to be added, a storage tank storing the heat transfer medium is connected to the charging port through a pipeline, and a conveying pump on the pipeline is started to add the heat transfer medium into the first pipeline 17; or the valve is directly opened, and the heat transfer medium is manually added by an operator. In addition to the above structure, the heat exchange area can also use other structures to realize heat exchange between the heat transfer medium and the fecal water.

[0066] In addition, the heating chamber 6 is open at the top, and the first pipeline 17 is coated with a heat-absorbing coating. The heat-absorbing coating improves the ability of the first pipeline 17 to absorb sunlight and improves the heating efficiency of the heat transfer medium. The heat-absorbing coating can be a coating with black pigments such as carbon black, iron oxide black and copper oxide as the main filler, or other coatings that can improve the sunlight absorption capacity. The heating chamber 6 is provided with a reflective layer. The reflective layer increases the number of reflections of sunlight in the heating chamber 6, so that more sunlight can shine on the first pipeline 17, further improving the heating efficiency of the heat transfer medium. The reflective layer needs to be arranged to avoid the first pipeline 17. The reflective layer is bonded or welded in the heating chamber 6. The reflective layer can be a mirror or an aluminum foil layer or a silver-plated layer.

[0067] As Figure 1 , Figure 2As shown, the environment-friendly manure water heating device comprises a manure water chamber 3 for storing manure water, a heating chamber 6, a storage area comprising a storage chamber 8, a fourth pipeline 15 arranged in the storage chamber 8, a first pipeline 17 arranged in the heating chamber 6, the first pipeline 17 being a spiral pipeline at this time, a second pipeline 20 arranged in the manure water chamber 3, an air outlet pipe 7 arranged on the manure water chamber 3 and communicating with the manure water chamber 3, a first end of the fourth pipeline 15 communicating with a first end of the first pipeline 17, a second end of the first pipeline 17 communicating with a first end of the second pipeline 20 through a fifth pipeline, a second end of the second pipeline 20 communicating with a first end of a sixth pipeline 18, a second end of the sixth pipeline 18 communicating with a second end of the fourth pipeline 15, a first conveying pump 13 arranged on a region of the fourth pipeline 15 in the storage chamber 8, and a second conveying pump 19 arranged on a region of the sixth pipeline 18 close to the heating chamber 6; when it is needed to heat the manure water, the first conveying pump 13 is started to convey the heat transfer medium into the first pipeline 17, the second conveying pump 19 is started to convey the heat transfer medium into the second pipeline 20 to heat the manure water after the heat transfer medium is heated to a required temperature, and the water vapor generated by the heating is discharged from the air outlet pipe 7; the heat transfer medium after heat exchange is returned to the storage chamber 8 through the sixth pipeline 18.

[0068] Moreover, the first support 9a and the second support 9b are arranged on the frame 2 in a spaced manner from top to bottom, the first mounting rack 4a and the second mounting rack 4b are symmetrically arranged on the first support 9a, the focusing unit has three first lenses 1, the first lenses 1 are Fresnel lenses, one of the Fresnel lenses is arranged on the first mounting rack 4a, and the other two Fresnel lenses are arranged on the second mounting rack 4b, three second lenses 5 are arranged on the second support 9b, a plurality of first fixing holes 11 are arranged on the frame 2 in an equidistant manner, the first support 9a and the second support 9b are also provided with the first fixing holes 11, and the first fixing member 14 is a fastening structure such as a bolt (the first fixing hole 11 and the first fixing member 14 are arranged in a matched manner, the first fixing member 14 is a bolt when the first fixing hole 11 is a threaded hole, and the first fixing member 14 is a pin shaft matched with the first fixing hole 11 when the first fixing hole 11 is a pin hole); when it is needed to adjust the height of the first lens 1 and the second lens 5 on the frame 2, the corresponding first fixing member 14 can be unscrewed, the first support 9a or the second support 9b can be moved, and the first support 9a or the second support 9b can be fixed on the frame 2 through the first fixing member 14 after the first lens 1 or the second lens 5 is moved to a corresponding position.

[0069] The Fresnel lens in the middle position is rotatably connected to the first mounting bracket 4a and the second mounting bracket 4b via a rotating shaft 16. The first mounting bracket 4a and the second mounting bracket 4b extend from both ends of the rotating shaft 16. Nuts and other fasteners can be fixed to both ends of the rotating shaft 16. When the Fresnel lens in the middle position needs to be rotated, the nut is loosened, and the rotating shaft 16 is rotated to adjust the tilt angle of the Fresnel lens in the middle position. When the Fresnel lens in the middle position is rotated to its correct position, the nut is tightened onto the rotating shaft 16, and both ends of the rotating shaft 16 are secured to the first mounting bracket 4a and the second mounting bracket 4b respectively. The other two Fresnel lenses are connected to the base frame via a metal-shaped flexible tube 10. The three reflectors are fixed to the second bracket 9b via the metal-shaped flexible tube 10. At this time, the second fixing component 12 is the metal-shaped flexible tube 10, and both ends of the metal-shaped flexible tube 10 are fixedly connected to the second lens 5, the frame 2, or the second bracket 9b respectively. The attitude of the corresponding Fresnel lens and the second lens 5 can be adjusted by bending the metal-shaped flexible tube 10.

[0070] Furthermore, several casters and mechanical latches can be installed at the bottom of the frame 2 to lock the casters. This allows operators to unlock the latches and move the frame 2 according to changes in sunlight or changes in the user's workspace, thus changing the spatial position of the environmentally friendly sewage heating device. Once the environmentally friendly sewage heating device is in the desired position, the latches can be adjusted to lock the casters, preventing accidental movement of the frame 2. The casters and locking mechanisms are existing technologies and will not be described in detail here.

[0071] like Figure 8 As shown, this is a schematic diagram of the temperature change of the heat transfer medium exposed to sunlight and the heat transfer medium heated by the first lens 1 through the first pipe 17. It can be seen that the heat absorption efficiency is low when the heat transfer medium absorbs sunlight by itself, while the temperature rises faster when the heat transfer medium is heated by the first pipe 17. At this time, the heat transfer medium is heat transfer oil and the first pipe 17 is a copper pipe.
