Description

Technical Field

[0001] The invention relates to the technical field of drying photovoltaic supporting facilities, and in particular to a photovoltaic solar energy heat pump combined drying system. Background Art

[0002] Against the backdrop of growing global energy demand and increasing awareness of environmental protection, the development and application of new energy technologies have become the focus of global attention.

[0003] Photovoltaic technology, as a technology that directly converts solar energy into electrical energy, has the advantages of being clean, renewable, and pollution-free, and has been widely used around the world. With the continuous advancement of technology, the efficiency of photovoltaic cells has been continuously improved and the cost has been continuously reduced, making photovoltaic power generation competitive in more fields. At the same time, as one of the most abundant renewable energy sources on the earth, solar energy has great potential for utilization, especially in the field of drying. Solar drying technology has shown significant energy-saving and environmental protection effects.

[0004] Photovoltaic modules convert solar radiation into electrical energy and generate heat at the same time. The heat absorber absorbs the heat generated by the photovoltaic modules and transfers it to the heat pump system. The heat pump system uses thermal energy to work and realizes the extraction and transfer of thermal energy through the phase change process of the circulating working fluid. Therefore, when drying some materials, a photovoltaic solar heat pump combined with a drying system can be used to divert heat to the drying equipment to dry the materials and reduce energy consumption. In the prior art, when the drying system dries the materials, the photovoltaic solar heat pump is usually at a long distance from the drying equipment and transports the heat energy through a pipeline. However, part of the heat energy is lost during the transportation process, resulting in the heat energy flowing to the drying equipment failing to reach the specified value, thereby resulting in a low working efficiency of the heat pump combined with a drying system and a slow drying efficiency of the materials. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a photovoltaic solar heat pump combined drying system to solve the problems mentioned in the above background technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The present invention is a photovoltaic solar heat pump combined drying system, which specifically comprises: a photovoltaic component frame and a drying cylinder component, wherein a double-end drive motor is installed on one side of the photovoltaic component frame, and a fixed bracket is installed at the edge position of the rear side of the photovoltaic component frame; a positioning rod is installed on the inner side of the fixed bracket; a guide piece is slidably installed on the outer side of the positioning rod; an adjustment plate is installed on the outer side of the guide piece; a material feed port is provided on the top of the drying cylinder component, and a flow guide cover is provided on the side of the drying cylinder component; a fan is installed on the outer side of the flow guide cover; a collecting cover is installed on the other side of the drying cylinder component; an air pump is installed on the outer side of the collecting cover, and a shunt pipe is installed on the output end of the air pump.

[0008] Furthermore, a front glass plate, a photovoltaic panel assembly and a heat collecting tube assembly are installed on the inner side of the photovoltaic assembly frame; the photovoltaic panel assembly is located on the inner side of the front glass plate; and a rear glass plate is installed on the rear side of the photovoltaic assembly frame.

[0009] Furthermore, guide grooves are provided at the top and bottom of the photovoltaic component frame; two traction sliders are slidably installed inside the guide grooves.

[0010] Furthermore, a cleaning plate is installed between the two traction sliders; a rubber scraper is provided on the inner side of the cleaning plate, and the rubber scraper is installed on the outer sides of the front glass plate and the rear glass plate; a driving rod is installed on the output end of the double-ended driving motor on the side of the photovoltaic component frame.

[0011] Furthermore, transmission wheels are installed at both ends of the top and bottom of the photovoltaic component frame, and conveyor belts are installed on the transmission wheels; the side ends of the driving rod are connected to the transmission wheels at the top and bottom of the photovoltaic component frame; and the outer end of the traction slider is connected to the conveyor belt.

[0012] Furthermore, a reflector is installed on the front side of the adjustment plate; and fixing bolts are installed on the top and bottom of the fixing bracket.

[0013] Furthermore, an upper guide tube is installed on the inner top of the guide cover; an upper guide tube is installed on the top of the heat collecting tube assembly; the side end of the upper guide tube passes through the side of the photovoltaic assembly frame and is connected to the upper guide tube; a lower guide tube is installed on the inner bottom of the guide cover.

[0014] Furthermore, a heat sink is installed between the top of the lower guide tube and the bottom of the upper guide tube.

[0015] Furthermore, a lower guide pipe is installed at the bottom of the thermal collection tube assembly; a return pipe is installed at the side end of the lower guide pipe passing through the side of the photovoltaic assembly frame; a temporary storage and collecting station is installed at the side end of the return pipe; a driving pump is installed at the top of the temporary storage and collecting station, and the output end of the driving pump is connected to the outer end of the lower guide pipe.

[0016] Furthermore, the outer sides of the upper guide pipe, the lower guide pipe and the return pipe are all wrapped and installed with a protective pipe; and the side end of the diverter pipe is connected to the outer side of the protective pipe.

[0017] The present invention provides a photovoltaic solar heat pump combined drying system, which has the following beneficial effects:

[0018] When the present invention is in use, the pipeline for conveying heat energy is protected by using a protective tube, so as to reduce the loss of heat energy during the flow process. When the heat pump combined drying system dries the material, the heated heat-conducting oil in the heat-collecting tube assembly flows along the upper guide tube to the upper guide tube, flows through the heat sink to the lower guide tube and the return tube for circulation. During the flow of the heat-conducting oil, the protective tube is located on the outer sides of the upper guide tube, the lower guide tube and the return tube to block the heat, and part of the heat carried by the dried airflow flows to the inside of the protective tube through the diverter tube, slightly heats the outer sides of the upper guide tube, the lower guide tube and the return tube, and reduces the temperature difference between the inside and outside of the pipeline, thereby reducing the problem of heat energy loss during the flow of the heat-conducting oil carrying heat energy, so that the heat energy value flowing into the drying equipment is higher, and the efficiency of the material drying process is improved. The heat-conducting oil is circulated, so that the efficiency of heat collection of the heat-conducting oil is improved, and the heat energy circulation rate is high.

[0019] In addition, by using the reflector on the adjustment plate to reflect and guide the sunlight, the efficiency of heat absorption is improved. When the heat pump combined drying system is drying the material, the position of the adjustment plate is adjusted on the rear side of the photovoltaic module frame so that the adjustment plate drives the reflector to a suitable tilt angle to reflect the oblique sunlight, especially when the sun is rising or setting. The oblique sunlight shines on the reflector and then reflects onto the heat collecting tube assembly, so that the heat collecting tube assembly can fully absorb heat energy, provide sufficient heat for the drying system, and ensure the drying effect of the material.

[0041] In the embodiment of the present disclosure, when the heat pump combined drying system is drying the material, the fixed bracket 101 drives the photovoltaic module frame 1 to be at a suitable tilt angle, and the light is irradiated on the photovoltaic panel assembly 103 through the front glass plate 102 to generate electricity. The heat absorbed by the photovoltaic panel assembly 103 is transferred to the heat collecting tube assembly 104. The heat collecting tube assembly 104 is installed in a certain order, and the heat collecting tube assembly 104 is convenient for absorbing heat. The rear glass plate 105 blocks the rear side of the heat collecting tube assembly 104 to reduce the problem of dust adhering to the heat collecting tube assembly 104.

[0043] Embodiment 3, on the basis of embodiment 1, a material feed port is provided at the top of the drying cylinder assembly 3, and a guide hood 301 is provided on the side of the drying cylinder assembly 3; a fan is installed on the outside of the guide hood 301; a collecting hood 309 is installed on the other side of the drying cylinder assembly 3; an air pump is installed on the outside of the collecting hood 309, and a shunt pipe 3010 is installed on the output end of the air pump; an upper guide pipe 302 is installed on the top of the inner side of the guide hood 301; an upper guide pipe 303 is installed on the top of the heat collecting tube assembly 104; the side end of the upper guide pipe 303 passes through the side of the photovoltaic assembly frame 1 and is connected to the upper guide pipe 302; a lower guide pipe 304 is installed on the bottom of the inner side of the guide hood 301; the top of the lower guide pipe 304 and the upper guide A heat sink 305 is installed between the bottom of the tube 302; a lower guide pipe 308 is installed at the bottom of the heat collecting tube assembly 104; a return pipe 307 is installed at the side end of the lower guide pipe 308 passing through the side of the photovoltaic assembly frame 1; a temporary storage and collecting station 306 is installed at the side end of the return pipe 307; a driving pump is installed on the top of the temporary storage and collecting station 306, and the output end of the driving pump is connected to the outer end of the lower guide pipe 304; the outer sides of the upper guide pipe 302, the lower guide pipe 304 and the return pipe 307 are all wrapped and installed with a protective pipe 3011; the side end of the shunt pipe 3010 is connected to the outer side of the protective pipe 3011. When the heat pump combined drying system is drying the material, the internal storage of the drying cylinder assembly 3 has the material to be dried. The dried material is stored with heat transfer oil in the temporary storage and collecting station 306, the upper guide pipe 302, the heat sink 305, the lower guide pipe 304, the upper guide pipe 303, the return pipe 307, the lower guide pipe 308 and the heat collecting tube assembly 104. The heat transfer oil in the heat collecting tube assembly 104 flows outward along the upper guide pipe 303 after being heated to a certain temperature. The heat transfer oil carries heat energy through the upper guide pipe 302 to the inside of the heat sink 305. The fan outside the guide cover 301 works, and the generated airflow exchanges heat when it contacts the heat sink 305, so that the hot air flows to the inside of the drying cylinder assembly 3 to dry the material. After the heat of the heat transfer oil is lost, it passes through the lower guide pipe 30 4 flows to the temporary storage and collection station 306, and the driving pump on the temporary storage and collection station 306 works to make the heat transfer oil flow to the lower guide pipe 308 through the return pipe 307, so that the heat transfer oil enters the heat collection pipe assembly 104 again for heat storage, so that the heat transfer oil is circulated. The slightly hot airflow after drying in the drying cylinder assembly 3 is collected by the collecting cover 309 and then flows to the inside of the protective pipe 3011 through the air pump and the diverter pipe 3010. The protective pipe 3011 is located on the outside of the upper guide pipe 302, the lower guide pipe 304 and the return pipe 307. The slightly hot airflow heats the outside of each conduit to reduce the temperature difference, so that the heat loss of the heat transfer oil is reduced during the flow process, and the efficient drying treatment of the material is guaranteed.

[0044] The steps include:

[0045] First, light passes through the front glass plate 102 and irradiates the photovoltaic panel assembly 103 to generate electricity, and the heat is transferred to the heat collecting tube assembly 104;

[0046] Second, the adjustment plate 202 drives the reflector 203 to be at a suitable tilt angle to reflect the light onto the heat collecting tube assembly 104;

[0047] Third, the cleaning plate 108 cleans the outer side of the front glass plate 102 and the outer side of the rear glass plate 105, and the light is irradiated through the clear front glass plate 102 and the rear glass plate 105;

[0048] Fourth, the drying cylinder assembly 3 stores materials to be dried;

[0049] Fifth, after the heat transfer oil is heated to a certain temperature, it flows outward along the upper guide pipe 303, passes through the upper guide pipe 302 and flows into the heat sink 305, and the hot air flows into the drying cylinder assembly 3 to dry the material;

[0050] Sixth, the heat transfer oil flows back to the heat collecting tube assembly 104 to store heat;

[0051] Seventh, the protection tube 3011 is located outside the upper guide tube 302, the lower guide tube 304 and the return tube 307, and the slightly hot airflow heats the outside of each conduit.

[0052] The working principle of this embodiment is as follows: when in use, light is irradiated on the photovoltaic panel assembly 103 through the front glass plate 102 to generate electricity, and the heat absorbed by the photovoltaic panel assembly 103 is transferred to the heat collecting tube assembly 104. The sliding guide 201 on the outer side of the positioning rod 2 drives the adjustment plate 202 to be at a suitable tilt angle, and the adjustment plate 202 drives the reflector 203 to be at a suitable tilt angle. The reflector 203 reflects the light to the bottom of the heat collecting tube assembly 104, and the heat collecting tube assembly 104 fully absorbs the heat energy. The double-end servo motor on the side of the photovoltaic assembly frame 1 regularly drives the driving rod 109 to rotate, and the two ends of the driving rod 109 drive the transmission wheels at the top and bottom ends of the photovoltaic assembly frame 1 to drive the conveyor belt 1010 to reciprocate, and the conveyor belt 1010 drives the traction slider 107 to move along the guide slide 106. The two traction sliders 107 drive the cleaning plate 108 to clean the outside of the front glass plate 102 and the outside of the rear glass plate 105, and the light passes through the clear front glass plate 102 and the rear glass The plate 105 heats the heat transfer oil in the heat collecting tube assembly 104. The drying cylinder assembly 3 stores the material to be dried. After the heat transfer oil in the heat collecting tube assembly 104 is heated to a certain temperature, it flows outward along the upper guide pipe 303 above, flows through the upper guide pipe 302 and flows into the heat sink 305. The airflow generated by the fan outside the guide cover 301 contacts the heat sink 305 for heat exchange. The hot air flows into the drying cylinder assembly 3 to dry the material. The heat transfer oil flows to the temporary storage through the lower guide pipe 304. The collecting station 306 then enters the heat collecting tube assembly 104 through the return pipe 307 and the lower guide pipe 308 to store heat. The slightly hot airflow after drying in the drying cylinder assembly 3 is collected by the collecting cover 309 and then flows into the protective pipe 3011 through the diversion pipe 3010. The protective pipe 3011 is located on the outside of the upper guide pipe 302, the lower guide pipe 304 and the return pipe 307. The slightly hot airflow heats the outside of each conduit to reduce the temperature difference and reduce the heat loss of the heat transfer oil during the flow.
