Description

A drying room with bottom air supply

technical field

The utility model relates to the technical field of drying equipment, in particular to a drying room with air supply from the bottom.

Background technique

As an indispensable process in many industries, drying operation involves a wide range of areas of the national economy. During the processing of many products such as grain, food, fruit, medicinal materials, wood, leather, rubber and ceramics, drying operations have a great impact on the quality and cost of products. The energy consumption of drying operation is relatively high. According to incomplete statistics, 20% to 25% of the world's energy is used for industrial thermal drying; in my country, drying operation is also one of the largest energy consumers, and its energy consumption accounts for 12% of the total energy consumption of the national economy. %about. At present, in the drying process, there are mainly problems such as uneven environmental wind speed and flow field, uneven temperature and humidity, etc., resulting in a passive situation of uneven quality of dried products.

Utility model content

In order to solve the above problems, the utility model provides a drying room with air supply from the bottom, in order to meet the requirements of materials on temperature, humidity and air volume, ensure the drying quality of materials, realize uniform and stable temperature and humidity in the drying room, and uniform wind speed and flow field Reasonable technical effect.

In order to achieve the above object, the technical solution of the utility model is:

A drying room with air supply from the bottom, comprising a drying room, a circulation fan is provided on one side of the bottom of the drying room, a heater is provided on the top of the circulation fan, an air return port is provided on the top of the heater, and the drying The bottom of the room is equipped with an elevated mesh floor to form an air supply channel. The air outlet of the circulation fan is aligned with the air blast at the inlet of the air supply channel. The first air guide plate and the second air guide are evenly distributed in the air supply channel. plate.

Compared with the prior art, the utility model has the beneficial effects of:

The utility model makes the flow field and the temperature and humidity field of the whole drying environment uniform, which determines the stability of the drying quality and the improvement of the production efficiency. At the same time, the temperature and humidity of the drying room are stable, the wind speed is reasonable, the quality of the material is guaranteed, the drying time is shortened, the energy is saved, the drying process of high efficiency and energy saving is realized, and the passive situation of uneven quality of dried products is solved. And further reduce the energy consumption of the drying process, reduce the cost, and have obvious economic benefits.

Detailed ways

The content of the present utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

Example 1:

A drying room with air supply from the bottom is characterized in that it includes a drying room 1 , and a circulation fan 20 is provided on one side of the bottom of the drying room 1 for controlling the air volume in the drying room 1 . The top of the circulating fan 20 is provided with a heater 10 to provide hot air flow for the drying room 1 . The upper part of the heater 10 is provided with an air return port 70, and the bottom of the drying room 1 is provided with an elevated mesh floor 60 to form an air supply channel, and the air outlet of the circulating fan 20 is aligned with the air blast port 30 at the inlet of the air supply channel. The first air deflector 40 and the second air deflector 50 are evenly distributed in the air supply channel.

During the drying process of the material in the drying room 1, the ambient air is heated by the heater 10, then passes through the circulating fan 20, and is sent into the air supply channel by the air blower 30, and the first air deflector 40 installed in the bottom air supply channel is used on the one hand The hot air flow in the front of the air duct is evenly passed through the mesh floor 60 and enters the drying room 1 to reduce the dead angle of temperature and humidity; on the other hand, a uniform hot air flow is provided behind the air supply channel at the bottom. The second air deflector 50 installed in the bottom air supply channel will send the hot air flow over, and the hot air flow at the back of the bottom air supply channel will evenly enter the drying room 1 through the mesh floor 60 through adjustment. Like this, owing to mesh floor 60 has the hole of different caliber according to the front and back position of air channel. Thereby, the flow field of the hot air flow entering the drying room 1 is guaranteed to be uniform, the temperature and humidity field is uniform, and the ventilation rate and the uniformity of the air distribution in the gap between the drying materials are increased at the same time. The material exchanges heat with the hot air in the drying room 1 through convection, and the moisture absorbs heat and evaporates to produce hot and humid air, which is sent to the heater 10 again through the air return port 70, reheated and circulated, and sent to the bottom air supply channel.

The above-mentioned embodiments are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to allow those of ordinary skill in the art to understand the content of the present utility model and implement it accordingly, and cannot limit the protection scope of the present utility model with this . All equivalent changes or modifications made according to the essence of the content of the present invention shall fall within the scope of protection of the present invention.
