Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic panel recycling technology, specifically to a power roller cooling device for a photovoltaic panel pyrolysis furnace. Background Technology
[0002] In the recycling and processing of retired photovoltaic panels, in addition to inorganic components such as glass and metal, the treatment of organic materials such as backsheets and encapsulating films is a major challenge. Photovoltaic panel pyrolysis equipment transforms these organic components into recyclable energy or chemical raw materials through high-temperature pyrolysis reactions under a controlled atmosphere, while simultaneously achieving complete separation from inorganic materials, providing key technological support for the resource utilization of photovoltaic panels.
[0003] The pyrolysis furnace body is the core component of the equipment, typically employing a horizontal or vertical structure. It is constructed from high-temperature resistant alloy steel plates and lined with refractory insulation material to minimize heat loss. The furnace body is internally divided into three functional zones: a preheating zone, a pyrolysis zone, and a cooling zone. The preheating zone heats the crushed photovoltaic panel material to 100℃-300℃, removing moisture and low-boiling-point volatile organic compounds. The pyrolysis zone is the core reaction area, with the temperature controlled between 400℃-800℃. Within this range, the polymer materials (such as polyvinyl fluoride and polyester) and encapsulating films (such as EVA) of the backsheet undergo chain scission decomposition, transforming into pyrolysis gas and a small amount of pyrolysis oil. The cooling zone uses a water-cooling or air-cooling system to cool the pyrolysis solid residue (mainly inorganic components such as glass, silicon wafers, and metals) to a temperature suitable for subsequent processing.
[0004] Because the photovoltaic panel pyrolysis furnace operates at high temperatures, heat is transferred along the power roller to the motor side, causing the motor and other components to overheat, affecting the stable operation and service life of these components. Utility Model Content
[0005] This utility model proposes a cooling device for the power roller of a photovoltaic panel pyrolysis furnace, which solves the problem of heat transfer from the power roller of the photovoltaic panel pyrolysis furnace to the motor and other components.
[0006] The technical solution of this utility model is as follows: a power roller cooling device for a photovoltaic panel pyrolysis furnace, comprising bolts, a first roller, a heat-insulating roller, and a second roller. The first roller and the heat-insulating roller have flanges at both ends, and the second roller has a flange at one end and a keyway at the other end. The first roller, the heat-insulating roller, and the second roller are connected by bolts. One end of the first roller is connected to the photovoltaic panel pyrolysis furnace, and one end of the second roller is connected to a reducer.
[0007] Preferably, the heat-insulating roller is a hollow cylinder.
[0008] Preferably, the heat-insulating roller flange has a groove on one side.
[0009] Preferably, the outer edge of the heat insulation roller is fitted with an upper waterproof cover and a lower waterproof cover. One end of the upper waterproof cover and the lower waterproof cover are hinged, and the other end is connected by a buckle. The outer edges of the upper waterproof cover and the lower waterproof cover are close to the groove. A water inlet pipe is connected to the top of the upper waterproof cover, and a drain pipe is connected to the bottom of the lower waterproof cover. A water collection pool is located at the end of the drain pipe, and a water pump is located in the water collection pool. The water pump is connected to the water inlet pipe.
[0010] Preferably, a heat insulation pad is provided between the first roller, the heat insulation roller, and the second roller.
[0011] Preferably, the heat insulation pad is made of ceramic fiberboard.
[0012] Preferably, the first roller, the heat-insulating roller, and the second roller are made of high-manganese alloy steel.
[0013] Preferably, the upper waterproof cover and the lower waterproof cover are made of stainless steel.
[0014] The principle of this invention: The pyrolysis furnace body is internally divided into three functional sections: a preheating zone, a pyrolysis zone, and a cooling zone. The preheating zone heats the crushed photovoltaic panel material to 100℃-300℃, removing moisture and low-boiling-point volatile organic compounds. The pyrolysis zone is the core reaction area, with the temperature controlled between 400℃-800℃. When the pyrolysis furnace is operating, the furnace body rotates. The furnace body is connected to the power unit via a power roller. At this time, the high temperature of the furnace body transfers heat along the power roller to the power unit (motor or reducer). To prevent heat transfer to the power unit, this invention mainly consists of a first roller, a heat-insulating roller, and a second roller. The first roller, heat-insulating roller, and second roller are connected to each other by bolts, facilitating installation, debugging, and regular maintenance. One end of the first roller is connected to the pyrolysis furnace body, and one end of the second roller is connected to the power unit. The heat-insulating roller is a hollow cylinder. The system minimizes heat transfer to the power unit while ensuring stable torque transmission, thus guaranteeing normal operation. A heat-insulating pad between the first roller, the heat-insulating roller, and the second roller further prevents heat transfer to the power unit. Additionally, an upper and lower waterproof cover are fitted around the outer edge of the heat-insulating roller. A water inlet pipe is connected to the top of the upper waterproof cover and is connected to a water pump. The pump pumps cooling water into the inlet pipe, which then sprays cooling water onto the outer edge of the heat-insulating roller, reducing its temperature. Cooling water dripping from the outer edge of the heat-insulating roller is recycled through a drain pipe at the bottom of the lower waterproof cover, ensuring the cooling water can be reused and preventing overflow between the upper and lower waterproof covers. Through these technical solutions, the heat-insulating roller remains at room temperature and effectively blocks heat transfer from the pyrolysis furnace, protecting the power unit from external high temperatures and ensuring stable operation.
[0015] The beneficial effects of this utility model are as follows: A cooling device for the power roller of a photovoltaic panel pyrolysis furnace has a compact structure, low manufacturing cost, convenient installation and maintenance, and is safe and reliable. It can effectively reduce the heat transfer from one side of the pyrolysis furnace to the power unit, protect the power unit from the influence of high external temperatures, and ensure the stable operation of the power unit.

The first roller 101, the heat-insulating roller 102, and the second roller 103 are connected by bolts 106. One end of the first roller 101 is connected to the photovoltaic panel pyrolysis furnace, and one end of the second roller 103 is connected to a reducer. In this embodiment, the bolted connection between the first roller 101, the heat-insulating roller 102, and the second roller 103 facilitates installation and maintenance. The flange 104 on the outside of the first roller 101 connects to the pyrolysis furnace body, and the keyway 108 end of the second roller 103 allows connection to a reducer or a motor, reducing manufacturing and installation difficulties.
[0022] Specifically, the heat-insulating roller 102 is a hollow cylinder. In this embodiment, the heat-insulating roller 102 adopts a hollow cylindrical structure, which reduces the transfer of heat to the power device side while ensuring stable torque transmission, thus ensuring the normal operation of the power device.

In this embodiment, the groove 107 limits the movement of the upper waterproof cover 109 and the lower waterproof cover 110 to prevent cooling water from overflowing and polluting the working environment.
[0025] Specifically, such as Figure 1 As shown, a heat insulation pad 105 is provided between the first roller 101, the heat insulation roller 102, and the second roller 103. In this embodiment, the heat insulation pad 105 further blocks heat from being transferred to the power unit side.
[0026] Specifically, the heat insulation pad 105 is made of ceramic fiber board. In this example, the heat insulation pad 105 made of ceramic fiber board has the advantages of being lightweight, high temperature resistant, having good thermal stability, low thermal conductivity, low specific heat, and resistance to mechanical vibration.
[0027] Specifically, the first roller 101, the heat-insulating roller 102, and the second roller 103 are made of high-manganese alloy steel. In this embodiment, the first roller 101, the heat-insulating roller 102, and the second roller 103 made of high-manganese alloy steel have good impact resistance, extrusion resistance, and wear resistance, and have a long service life.
