TECHNICAL FIELD

[0001] The present application relates to the technical field of drying treatment, in particular to an energy-saving drying device. BACKGROUND

[0002] Current drying equipment is mostly designed with a single temperature zone, which cannot accurately control the drying requirements at different stages, resulting in energy waste. There is an increasing demand for high-efficiency and low-energy-consumption drying equipment in the market. Traditional equipment is inconvenient to install and maintain, and is difficult to adapt to modern production line adjustments.

[0003] To improve drying efficiency and reduce energy consumption, the industry has developed improvements such as multi-layer drying bed structure, variable frequency speed fan, and infrared heater. These methods have improved drying efficiency, but also have shortcomings such as increased equipment height and complexity, high cost, difficulty in maintenance, and high power consumption.

[0004] Therefore, the existing drying equipment has high energy consumption and poor flexibility, cannot meet the optimal drying conditions for different materials, resulting in energy waste, high installation and maintenance costs, and is not suitable for modern production line adjustment requirements. There is an urgent need for new drying equipment to improve drying efficiency, reduce energy consumption, and be easy to install and maintain.

[0005] Therefore, the present application proposes an energy-saving drying device. CONTENT OF THE INVENTION

The multi-section structure design allows each drying section to independently control temperature and air volume, achieving more precise control, improving drying uniformity and quality, and greatly reducing installation and maintenance costs of the equipment. The design is easy to install and maintain, facilitating overall layout adjustment of the production line. The automatic and intelligent control system not only simplifies the operation process, but also improves production efficiency and reduces the possibility of manual intervention. The use of waste heat recovery technology significantly reduces energy consumption and meets the requirements of energy saving and environmental protection.

[0007] To achieve the above purpose, the present application adopts the following technical solutions:

[0008] An energy-saving drying device includes a drying chamber, a temperature control system, a hot air circulation system, a sensor, a central control system, and a waste gas collection device. The temperature control system is arranged on both sides of the inside of the drying chamber. The hot air circulation system is arranged at the bottom end of the inside of the drying chamber. The sensor is distributed at the top end of the inside of the drying chamber. The inside of the drying chamber is divided into multiple independent drying sections, each of which is provided with a separate air inlet and air outlet.

[0009] As a preferred embodiment, the sensor includes a temperature sensor and a humidity sensor, and a plurality of temperature sensors and humidity sensors are installed in each drying section.

[0010] The temperature sensors and humidity sensors installed in each drying section are used to monitor the environmental parameters in real time, thereby improving the practicability of the device.

[0011] As a preferred embodiment, the temperature control system is composed of a controller and an electric heating element, the controller is fixedly connected to the exhaust gas collecting device, and the electric heating element is installed on the inside of the drying chamber.

[0012] By setting the controller and the electric heating element, the temperature in each drying section can be automatically adjusted according to the data feedback by the sensors, thereby improving the practicability of the device.

[0013] As a preferred embodiment, the hot air circulation system is composed of centrifugal fans and air ducts, and each centrifugal fan is fixedly connected to the bottom end of the inside of the drying chamber.

[0014] By setting the centrifugal fans and air ducts, it is ensured that the hot air is uniformly distributed in the entire drying section, thereby improving the practicability of the device.

[0015] As a preferred embodiment, the air outlet end of each centrifugal fan is fixedly connected with an air duct, and one end of each air duct is in communication with the corresponding air inlet.

[0016] By starting the hot air circulation system, the centrifugal fan starts to work, and fresh air enters the drying section through the air duct, thereby improving the practicability of the device.

[0017] As a preferred embodiment, the central control system receives data from various sensors, and the temperature control system and the hot air circulation system are controlled by the central control system.

[0018] The central control system receives data from various sensors, calculates the optimal drying parameters through an algorithm, and sends instructions to the temperature control system and the hot air circulation system, thereby improving the practicability of the device.

[0019] As a preferred embodiment, the drying chamber is provided with an exhaust gas collecting device.

[0020] By installing the exhaust gas collecting device around the drying chamber, the exhaust gas is preheated by the heat exchanger and enters the fresh air of the next drying process, thereby improving the practicability of the device.

[0021] The beneficial effects of the present application are:

[0022] 1. This energy-saving drying device is designed such that when the hot air circulation system is started, the centrifugal fan starts working, and fresh air enters the drying section through the air duct. The electric heating element is heated in a controlled manner to make the air reach the set temperature and form a hot air flow. The material is placed on the drying rack and passes through each drying section in sequence, receiving segmented countercurrent drying. The multi-segment structure design allows the temperature and air volume of each drying section to be independently adjusted, achieving more precise control and greatly improving the practicality of the device.

[0023] 2. This energy-saving drying device is equipped with built-in sensors to monitor the temperature and humidity changes of each section in real time. The data is transmitted back to the central control system, which dynamically adjusts the operating parameters of the temperature control system and the hot air circulation system according to the current status to ensure the best drying effect. The exhaust gas is collected and preheated by the heat exchanger to reduce energy consumption. After drying is completed, the system is shut down and the dried material is taken out, which greatly improves the practicality of the device. Attached Figure Description

The controller 21 is fixedly connected to the exhaust gas collection device 6, and the electric heating element 22 is installed on both sides inside the drying chamber 1. By setting the controller 21 and the electric heating element 22, the temperature in each drying section 11 can be automatically adjusted according to the data fed back by the sensor 4, thereby improving the practicality of the device.

[0033] Reference Figures 1-4 The hot air circulation system 3 consists of a centrifugal fan 31 and an air duct 32. Each centrifugal fan 31 is fixedly connected to the bottom of the drying chamber 1. By setting up the centrifugal fan 31 and the air duct 32, the hot air is evenly distributed throughout the drying section 11, thereby improving the practicality of the device.

[0034] Reference Figures 1-4 Each centrifugal fan 31 has a fixed air duct 32 at its outlet, and one end of each air duct 32 is connected to the corresponding air inlet 111. When the hot air circulation system 3 is started, the centrifugal fan 31 starts to work, and fresh air enters the drying section 11 through the air duct 32, thereby improving the practicality of the device.

[0035] Reference Figures 1-4 The central control system 5 receives data from each sensor 4, and both the temperature control system 2 and the hot air circulation system 3 are controlled by the central control system 5. By receiving data from each sensor 4 and calculating the optimal drying parameters through an algorithm, the central control system 5 sends instructions to the temperature control system 2 and the hot air circulation system 3, thereby improving the practicality of the device.

[0036] Reference Figures 1-3A waste gas collection device 6 is installed around the drying chamber 1. Through the waste gas collection device 6 installed around the drying chamber 1, the waste gas is preheated by the heat exchanger and enters the fresh air for the next drying process, thereby improving the practicality of the device.

[0037] Working principle: The central control system 5 is started, and initial drying parameters such as temperature, humidity, and time are set. The hot air circulation system 3 is started, and the centrifugal fan 31 starts working. Fresh air enters the drying section 11 through the air duct 32. The electric heating element 22 is heated in a controlled manner to make the air reach the set temperature and form a hot air flow. The material is placed on the drying rack and passes through each drying section 11 in sequence, receiving segmented countercurrent drying. The built-in sensor 4 monitors the temperature and humidity changes of each section in real time and transmits the data back to the central control system 5. The central control system 5 dynamically adjusts the operating parameters of the temperature control system 2 and the hot air circulation system 3 according to the current status to ensure the best drying effect. The exhaust gas is collected and preheated by the heat exchanger to reduce energy consumption. After drying is completed, the system is turned off and the dried material is taken out.
