Description

Technical Field

[0001] The utility model relates to the field of drying-related equipment, in particular to a photovoltaic drying box. Background Art

[0002] In the traditional flue-curing process, the control of temperature and humidity may not be accurate enough, resulting in unstable tobacco quality and prone to over-curing or under-curing. The use of solid fuels (such as firewood and coal) for combustion will produce a large amount of soot and harmful gas emissions, causing pollution to the atmospheric environment. Open-fire flue-curing has a certain fire risk, especially when the operation is improper or the equipment is aging. Long-term exposure to the smoke and harmful substances during the flue-curing process may pose a potential threat to the health of the staff. In addition, the existing flue-curing equipment has a low degree of automation and there are still defects in the internal structure. It is impossible to accurately understand the temperature and humidity inside, and basically operates by experience. The temperature and humidity inside are also uneven, which will affect the control of the quality of tobacco leaves. Therefore, a photovoltaic drying box is needed. Content of the Utility Model

Detailed Embodiments

[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments:

[0021] As Figure 1 shown, a photovoltaic drying box includes a box body 1 with a hollow cavity structure. An air source heat pump host 2 is correspondingly provided in the box body 1. The air source heat pump host 2 is powered by an external photovoltaic panel (not shown in the drawings, and its power supply principle and related connection structure are well-known technologies and will not be elaborated here). A box door 3 is correspondingly provided on one side of the box body 1, and a circulation air duct 4 is correspondingly provided on the other side of the box body 1. The air outlet of the air source heat pump host 2 and the circulation air duct 4 are arranged on the same side of the box body 1. The air source heat pump host 2 adopts frequency conversion technology, which is energy-efficient, pollution-free, and safe and reliable in operation. The related connection structure, principle, and working process of the air source heat pump host are well-known technologies and will not be elaborated here.

[0022] In this embodiment, the photovoltaic drying box is used for baking tobacco leaves. The photovoltaic drying box uses an air source heat pump host as the main component to provide load. The temperature and humidity during the drying process are automatically controlled, fully simulating the principle of natural air drying. The tobacco leaf baking is a continuous processing process. Whether it is the change of tobacco leaves or the regulation of baking process conditions, they are all progressive processes that are related to each other before and after, without distinct boundaries and stages. However, for the convenience of process operation, according to the differences in the characteristics before and after during the change process of tobacco leaves, as well as the different requirements for industrial conditions during the change process of tobacco leaves, in the actual working process of this application, the baking process is divided into several stages or periods: (1) yellowing stage (2) color fixing stage (3) stem drying stage. By dividing the stages, the process parameters in different stages are adjusted targeted to improve the drying efficiency and enhance the quality of tobacco leaves.

[0023] As Figures 2 - 4 shown, the circulation air duct 4 includes a symmetrically arranged first circulation air duct 41 and a second circulation air duct 42. The first circulation air duct 41 and the second circulation air duct 42 are respectively arranged at the left and right ends on a certain side of the box body 1. The first circulation air duct 41 and the second circulation air duct 42 are both arranged on the box body 1 on the side opposite to the box door 3. The first circulation air duct 41 and the second circulation air duct 42 are both composed of a plurality of horizontal grid-shaped air outlets, and the air outlets are evenly spaced on one side of the box body 1. Air is blown out from the air source heat pump host 2 and circulates through the first circulation air duct 41 and the second circulation air duct 42. By using air circulation, the drying time is short, and nearly half of the time can be saved. It also overcomes the disadvantages of high energy consumption and low thermal efficiency of traditional drying equipment.

[0024] One end of the box door 3 is correspondingly connected to the box body 1 through a hinge 5, and a door lock 6 is correspondingly arranged at one end of the box door 3. The detachable connection is carried out through the hinge 5 and the door lock 6, which is convenient for the entry and exit of tobacco leaves and improves work efficiency. A plurality of legs 7 are correspondingly arranged at the bottom of the box body 1.

[0025] A touch screen controller 8 is correspondingly provided inside the box body 1, and several temperature and humidity sensors 9 are also correspondingly provided inside the box body 1. The touch screen controller 8 is correspondingly electrically connected to the air source heat pump host 2 and the temperature and humidity sensors 9. The temperature and humidity sensors 9 are multiple ones arranged on the inner wall of the box body 1. In this embodiment, the touch screen controller 8 strictly monitors the temperature and humidity of the box body 1 through the temperature and humidity sensors, and timely adjusts the power of the air source heat pump host 2. The tobacco leaf drying process can be controlled throughout the whole process, the quality of the tobacco leaves is stable and uniform, and the finished product has a good color. Moreover, it can also reduce energy consumption, save energy, be hygienic and environmentally friendly. The internal circuit structure of the touch screen controller 8, its connection relationship with other components, as well as its working process and principle are well-known technologies and will not be elaborated here. In this embodiment, the touch screen controller 8 adopts an industrial-grade PLC touch screen controller, which is simple to operate, can turn on and off the machine and standby at a fixed time, set the temperature, etc., and can meet the drying requirements of different dried materials, and runs fully automatically and intelligently.

[0026] In this embodiment, the size of the photovoltaic drying box is: L 2.7m * D 1.6m * H 2.05m, the floor area is about 5 - 6 ㎡, and the installation is simple and convenient; the total power consumption of the photovoltaic drying box is at most about 9KW, and the oven volume is about 4.5 - 6m 3 , and 150 - 250 kg of tobacco leaves can be processed each time.

[0027] Although the technical solutions of the present invention have been described in detail and listed, it should be understood that for those skilled in the art, making modifications to the above embodiments or adopting equivalent alternative solutions are obvious to those skilled in the art. These modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
