Description

Technical Field

[0001] This utility model relates to the field of drying-related equipment, and in particular to a photovoltaic drying system. Background Technology

[0002] Tobacco drying systems are used to transform freshly harvested tobacco leaves into processable and usable tobacco products. This process promotes the fermentation and drying of tobacco leaves by controlling temperature, humidity, and other environmental factors, thereby developing the unique flavor and color of tobacco. Existing tobacco drying systems often require large amounts of firewood or coal as fuel, which is not only costly but also has a significant environmental impact. Tobacco drying systems and their related equipment (such as heating systems) require regular maintenance to ensure their proper operation, which also adds to the costs.

[0003] The steel support structure used in flue-cured tobacco is mainly used inside the tobacco drying system as a supporting structural component. Compared with ordinary steel structures, the high temperature during the tobacco drying process may cause thermal expansion and deformation of the steel. Moreover, the stability of the support structure may be affected under high temperature and heavy load. Therefore, a photovoltaic drying system is needed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, a photovoltaic drying system is provided.

[0005] This utility model is achieved through the following solution:

[0006] A photovoltaic drying system includes a steel frame support, a photovoltaic panel is correspondingly installed on the top of the steel frame support, a tobacco curing box and a power system are correspondingly installed inside the steel frame support, the power system includes an energy storage battery and a diesel generator, and the energy storage battery is electrically connected to the diesel generator and the photovoltaic panel respectively.

[0007] The steel structure support includes multiple columns connected to the ground, with a crossbeam corresponding to the top of each column, and a photovoltaic panel canopy corresponding to the top of each crossbeam.

[0008] The bottom of the column is provided with a T-shaped connecting base, which is connected to the concrete connecting column, and the bottom of the concrete connecting column is connected to the ground.

[0009] Several diagonal braces are provided between the columns, and the diagonal braces are arranged between each column.

[0010] The upper part of the photovoltaic panel canopy is provided with multiple photovoltaic panel connecting blocks, which are detachably connected to the photovoltaic panels.

[0011] The multiple columns are evenly arranged, and the steel structure support is divided into a tobacco curing box placement area, a power system placement area, a finished product placement area, and a raw material placement area.

[0012] The tobacco curing box and the power system are respectively installed in the tobacco curing box placement area and the power system placement area.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model discloses a photovoltaic drying system that uses photovoltaic panels as energy for drying, which is green, environmentally friendly and energy-saving. When the photovoltaic panels cannot provide enough power, a diesel generator is activated to ensure that the system can operate normally and production can continue.

[0015] 2. This application provides a reinforced steel support structure design for a photovoltaic drying system, ensuring sufficient strength and rigidity, and adding components such as diagonal braces and connecting bases to improve the stability of the structure.

[0016] 3. The photovoltaic drying system of this application has a photovoltaic panel connecting block on the top of the steel structure support, which detachably connects the photovoltaic panel to the top, making it easy to disassemble and clean. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figure 1 As shown, a photovoltaic drying system includes a steel frame 3, a photovoltaic panel 1 is correspondingly provided on the top of the steel frame 3, a tobacco curing box 4 and a power system 2 are correspondingly provided inside the steel frame 3, the power system 2 includes an energy storage battery 21 and a diesel generator 22, and the energy storage battery 21 is electrically connected to the diesel generator 22 and the photovoltaic panel 1 respectively.

[0023] In this embodiment, the photovoltaic panel 1 is a 12KWp photovoltaic device; the tobacco curing box 4 is a 9KW device, which can process 150-250kg at a time; the energy storage battery 21 is a 10.34KWh high-voltage lithium iron phosphate battery pack; and the diesel generator is a 10KW (3-phase 380V) device.

[0024] When the photovoltaic panels generate electricity, the electrical energy is converted into AC power through the inverter (in this embodiment, the inverter and the energy storage battery are integrated together) to first meet the needs of the tobacco curing box operation. If the needs are not met, the energy storage battery will assist in discharging to ensure its normal operation. If there is a power surplus for the operation of the tobacco curing box, the energy storage battery will be charged. When the photovoltaic panels do not generate electricity, the diesel generator is started to supply power. The power supply circuit is switched to ensure the normal operation of the tobacco curing box. If there is a power surplus during operation, the energy storage battery will be charged.

[0025] The specific working process of photovoltaic panels, the process of storing electricity in energy storage batteries, the process and principle of energy storage batteries supplying power to external devices, and related circuit structures are all well-known technologies and will not be elaborated here.

[0026] like Figure 2 , 3 As shown, the steel structure support 3 includes multiple columns 31 connected to the ground. A crossbeam 32 is provided on the top of the column 31 (the specific structure of the crossbeam 32 is known technology and will not be described in detail here). A photovoltaic panel canopy 33 is provided on the top of the crossbeam 32.

[0027] The bottom of each column 31 is provided with a T-shaped connecting base 37, which is connected to a concrete connecting column 36, the bottom of which is connected to the ground. Several diagonal braces 35 are provided between each column 31. The diagonal braces 35 ensure sufficient strength and rigidity, and the concrete connecting columns 36, inserted into the ground, provide sufficient grip for the system.

[0028] The upper part of the photovoltaic panel canopy 33 is provided with multiple photovoltaic panel connecting blocks 34 (the specific structure of the photovoltaic panel connecting blocks is known technology and will not be described in detail here). The photovoltaic panel connecting blocks 34 are detachably connected to the photovoltaic panels 1. During the tobacco curing process, soot and other residues may accumulate, affecting the cleanliness and service life of the system. The photovoltaic panel connecting blocks are set to detachably connect the photovoltaic panels to the top, which is convenient for disassembly and cleaning.

[0029] Multiple evenly spaced columns 31 divide the steel support frame 3 into a tobacco curing box placement area 38, a power system placement area 39, a finished product placement area 310, and a raw material placement area 311. A tobacco curing box 4 and a power system 2 are respectively installed in the tobacco curing box placement area 38 and the power system placement area 39. The complex structure may require professional installation and adjustment, increasing cost and time. This application simplifies the installation process by designing modular and standardized components such as the tobacco curing box placement area 38, the power system placement area 39, the finished product placement area 310, and the raw material placement area 311.
