Abstract
Description
Technical Field
[0001] This utility model belongs to the field of drying equipment, and in particular relates to a drying shed. Background Technology
[0002] Currently, in many places, coal slime is still dried in the open air. While outdoor drying is simple and inexpensive, it can easily cause environmental pollution. For example, wind can blow the coal slime away, polluting the surrounding environment and wasting resources. If drying equipment such as a rotary dryer is used, although it is more efficient and reduces environmental pollution, the cost will increase significantly. Utility Model Content
[0003] The purpose of this utility model is to provide a drying shed to solve the technical problems of how to reduce environmental pollution, improve drying efficiency, and reduce drying costs.
[0004] To achieve the above objectives, the specific technical solution of this utility model for a drying shed is as follows:
[0005] A drying shed includes a steel structure, walls around the perimeter of the steel structure, a roof at the top of the steel structure, a heat collection device on the outside of the walls of the drying shed, and a superheated pipe at the bottom of the shed, below the ground level. One end of the superheated pipe is connected to the heat outlet of the heat collection device, and the other end of the superheated pipe extends upward into the interior of the drying shed.
[0006] Furthermore, the heat collection device is a solar heat collection tube, which is installed on the outer side of the south-facing outer wall of the drying shed; the roof of the shed is inclined, with the south-facing side of the roof lower than the north-facing side, and the roof is made of plexiglass.
[0007] Furthermore, the superheated pipe includes a hot air inlet pipe located below the heat collection device, and the air inlet of the inlet pipe is connected to the air outlet of the heat collection device through a pipe. Several superheated branch pipes are connected to the inlet pipe, which are evenly distributed at the bottom of the drying shed and are all connected to the inlet pipe. The other end of the superheated branch pipe extends into the interior of the shed.
[0008] Furthermore, the steel structure includes columns, the lower ends of which are buried below ground level, and the columns are fixedly connected by connecting bars.
[0009] Furthermore, the top of the drying shed is equipped with a gas collection hood, one end of which is connected to the top of the shed and the other end is connected to the air inlet of the heat collection device; a blower is installed at the air inlet of the heat collection device.
[0010] The drying shed of this utility model has the following advantages: by using solar energy to heat and dry materials, the drying efficiency is improved, and energy waste and environmental pollution are reduced. In this application, by setting up a heat collection device and superheating pipes, the air is heated by solar energy, and the hot air is heated to the soil at the bottom of the shed through the superheating pipes to achieve heat storage and increase the temperature inside the shed. The soil after heat storage can continuously release heat for heating and drying materials. In addition, the hot air inside the shed continues to flow back to the heat collection device for heating through the air collection hood at the top of the shed, forming a circulation of hot air, which increases the temperature inside the shed, improves the heat utilization rate, and further improves the heating and drying effect of materials.

[0016] To better understand the purpose, structure, and function of this utility model, a drying shed of this utility model will be described in further detail below with reference to the accompanying drawings.
[0017] like Figure 1-4 As shown, the drying shed of this utility model includes a steel structure 1, which includes columns 11. The lower ends of the columns 11 are buried below the ground 2. The columns 11 are fixedly connected by connecting ribs 12, which enhances the connection strength of the steel structure 1. Walls 3 are provided around the steel structure 1, and a roof 4 is provided on the top of the steel structure 1. A heat collection device 5 is provided on the outside of the walls 3 of the drying shed. A superheated pipe 6 is provided at the bottom of the shed, that is, below the ground 2. One end of the superheated pipe 6 is connected to the heat outlet of the heat collection device 5 through a pipe, and the other end of the superheated pipe 6 extends upward into the interior of the drying shed.
[0018] The heat collection device 5 is a solar collector tube, which converts solar energy into heat for heating the air. This device is installed on the outer side of the south-facing exterior wall of the drying shed, which facilitates better absorption and conversion of solar energy. The heated air from the collector 5 enters the superheated pipe 6 through a pipe, transferring heat to the soil at the bottom of the shed. The soil acts as both a heat storage and release material. The hot air in the superheated pipe 6 heats the soil at the bottom of the shed. The coal sludge to be dried is then placed inside the drying shed. The soil at the bottom continuously releases heat, drying the coal sludge. Because the soil at the bottom stores a large amount of heat, it can continuously heat and dry the coal sludge even at night, and also collects heat... Device 5 continuously provides heat to the soil during the day, ensuring uninterrupted heating and drying of the coal slime in the drying shed, both day and night. Furthermore, before the coal slime is placed in the drying shed, the heat collection device 5 and the superheated pipe 6 can preheat the soil at the bottom, storing heat. After the coal slime is placed in the drying shed, heat is continuously provided for drying. Additionally, the outlet of the superheated channel extends into the shed, allowing hot air to enter and increasing the temperature inside, further improving drying efficiency. This application utilizes solar energy for heat generation and drying, employing environmentally friendly and clean energy, making it both environmentally friendly and efficient. Simultaneously, drying within the shed avoids environmental pollution caused by the coal slime.
[0019] The roof 4 of the greenhouse is inclined, with the south side of the roof 4 being lower than the north side. This allows the roof 4 to receive sunlight over a larger area for a longer period of time. At the same time, the roof 4 is made of plexiglass, which allows sunlight to pass through and provide heat to the inside of the greenhouse. The plexiglass can both allow sunlight to pass through and has a certain degree of heat preservation, further increasing the temperature inside the drying greenhouse, which is beneficial for the drying of coal slime.
[0020] The superheated pipe 6 includes a hot air inlet pipe located below the heat collection device 5. The inlet of the inlet pipe is connected to the outlet of the heat collection device 5 via a pipe. Several superheated branch pipes are connected to the inlet pipe. The superheated branch pipes are evenly distributed at the bottom of the drying greenhouse and are all connected to the inlet pipe. The other end of the superheated branch pipes extends into the greenhouse. Hot air flows into the inlet pipe through the pipe and then flows to the superheated branch pipes through the inlet pipe. The superheated branch pipes suddenly exchange heat with the surrounding soil, heating the soil at the bottom of the greenhouse. The air enters the greenhouse through the outlet of the superheated branch pipe.
[0021] To better utilize the heat generated by the heat collection device 5, a heat insulation layer is installed at the bottom of the superheated pipe 6. This insulation layer prevents heat from being transferred downwards and wasted. In addition, insulation layers are installed on the surrounding walls 3 of the drying greenhouse to improve the greenhouse's insulation effect and maintain a consistently high temperature inside the greenhouse.
[0022] In addition, to further utilize the heat, a gas collecting hood is installed on the top of the drying shed. The gas collecting hood is located at a high position on the shed roof 4. One end of the gas collecting hood is connected to the top of the shed, and the other end is connected to the air inlet of the heat collection device 5. The gas collecting hood can continue to return the hot air in the drying shed to the heat collection device 5 for further heating. The hot air heated by the heat collection device 5 continues to flow to the superheated pipe 6 and the drying shed, thus forming a circulation, which improves the heat utilization rate and the drying efficiency of the coal slime. In addition, a blower 7 is installed at the air inlet of the heat collection device 5, which can quickly blow the heated air in the heat collection device 5 to the superheated pipe 6 and the drying shed, forming a circulation of hot air.
[0023] In addition, exhaust vents are installed on the top of the drying shed to remove water vapor from the shed. In actual use, a conveyor belt can also be installed in the drying shed to transport coal slime, which can improve the drying efficiency of the material.
[0024] This application discloses a drying shed that utilizes solar energy to heat and dry materials, improving drying efficiency and reducing energy waste and environmental pollution. The shed is equipped with a heat collection device 5 and a superheated pipe 6, which heats the air using solar energy. This heated air is then passed through the superheated pipe 6 to heat the soil at the bottom of the shed, achieving heat storage and raising the internal temperature. The stored soil can continuously release heat for material drying. Furthermore, the hot air inside the shed is returned to the heat collection device 5 via air collection hoods on the shed roof 4, creating a hot air circulation system that increases the temperature inside the shed, improves heat utilization, and further enhances the material drying effect.
