Description

A hot air circulation drying oven

technical field

The utility model relates to drying equipment, in particular to a hot air circulation drying box.

Background technique

As a drying equipment, the hot air circulation drying oven is widely used in many fields such as pharmaceuticals and chemicals. The existing hot air circulation drying box mainly consists of a box body and a circulating fan, a heater, and a material chamber for holding materials to be dried are installed in the box body. The surface of the box body is provided with an air inlet connected to the box body. , the air entering the box is heated by the heater, and then circulates in the box under the action of the circulating fan, and enters the material room through the air inlet of the material room to dry the material to be dried. The air inlets of the material chamber of this hot air circulation drying box are mostly fixed-shaped vents, and their sizes cannot be adjusted, which makes it difficult to adjust the air volume of the material chamber. Although the temperature of the box and the material room can be monitored by sensors, the drying of the material is not only related to the temperature, but also directly related to the wind speed and air volume. Therefore, the existing structure is difficult to control the drying time of the dried materials, resulting in low production efficiency and waste of manpower due to the long drying time. Another situation is that the drying is uneven, which causes some materials to be dried too dry, while some materials cannot meet the drying requirements, which affects the drying quality of the materials.

Utility model content

In order to solve the above problems, the utility model patent provides a hot air circulation drying box, which can adjust the size of the air inlet of the material room by setting louvers on the side wall of the material room and adjusting the angle of the louver blades, so as to control the air entering the material room. The air volume is large, and the circulating hot air is converted into a smooth and uniform air flow through the louvers through the drainage channel and enters the material chamber to improve the drying efficiency and the consistency of material drying.

In order to achieve the above object, the technical scheme that the utility model takes is:

A hot air circulation drying box, which includes a box cavity formed by a box body, an air inlet is arranged on the box body, a filter is installed on the air inlet, and a Circulating fan and heater, the lower side of the inner cavity of the box is equipped with a material room for holding materials to be dried, and at least one louver for adjusting the air volume entering the material room is arranged on the side wall of the material room, and each louver Drainage channels formed by drainage plates are installed on the outside of the tank.

The drainage channel includes a vertical channel and a horizontal channel, one end of the horizontal channel communicates with the shutter, and the other end communicates with the vertical channel extending to the upper side of the box cavity.

The box body includes an inner wall, an outer wall located on the periphery of the inner wall, and an insulating layer located between the inner wall and the outer wall.

Compared with the prior art, the utility model has the following advantages:

1. The utility model adjusts the size of the air inlet of the material chamber by setting louvers on the side wall of the material chamber and adjusting the angle of the louver blades, so as to control the air volume entering the material chamber, and convert the circulating hot air into a stable air flow through the drainage channel. Uniform airflow enters the material chamber through the louvers, improving drying efficiency and improving the consistency of material drying.

2. An insulation layer is set on the box body to ensure a constant temperature of the box body and avoid energy waste caused by heat loss in the box body.

detailed description

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

Example

Please refer to Figure 1, a hot air circulation drying box, which includes a box body, the box body is composed of an inner wall 7, an outer wall 8 located on the periphery of the inner wall 7, and an insulating layer 9 located between the inner wall 7 and the outer wall 8, the insulating layer 9 can be realized by adopting thermal insulation material or thermal insulation material. A box inner cavity 1 is formed in the box body, an air inlet connected with the box inner cavity 1 is arranged on the box body, a filter 6 is installed outside the air inlet, and a circulating fan 5, heating container 2 and a material chamber 3 for holding materials to be dried. In order to adjust the air volume and wind speed uniformity entering the material chamber 3, in a preferred embodiment of the present utility model, at least one louver 4 for adjusting the air volume entering the material chamber 3 is provided on the side wall of the material chamber 3, A drainage channel formed by a drainage plate 10 is installed on the outside of each louver 4 . The drainage channel includes a vertical channel and a horizontal channel. One end of the horizontal channel communicates with the louver 4 , and the other end communicates with the vertical channel extending toward the upper side of the box cavity 1 . The vent size of the material chamber 3 can be adjusted by adjusting the rotation angle of the louver 4 blades, and the drainage channel converts the circulating hot air into a smooth and uniform air flow, and enters the material chamber 3 through the louver 4 . More preferably, the width (square) or radius (cylindrical) of all drainage channels can be set to be consistent.
