Description

Technical Field

[0001] This utility model relates to the field of drying room technology, and in particular to a structure for airflow guidance and exhaust. Background Technology

[0002] A drying room is a type of drying equipment, which refers to a combination of mechanical devices that use certain technical means to dry the surface of an object of moisture or other liquids. Popular drying technologies mainly include ultraviolet drying, infrared drying, electromagnetic drying, and hot air drying. Each of them has its own characteristics and is widely used in the drying of various mechanical equipment and food. The main heat source for drying in a drying room is dry hot air. Dry hot air is continuously transported into the drying room by a fan to dissipate the moisture in the object being dried, thereby achieving the drying purpose.

[0003] However, in the existing technology, the drying hot airflow in the drying room is supplied by a fan. The airflow input into the drying room by the fan is initially unevenly distributed, resulting in uneven heat distribution inside the drying room and reduced drying efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that the drying hot airflow in the drying room is supplied by a fan. The airflow entering the drying room from the fan is initially unevenly distributed, resulting in uneven heat distribution inside the drying room and reduced drying efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0006] A structure for airflow guidance and exhaust includes an air inlet pipe, one end of which is detachably and fixedly connected to the air outlet of a fan, and the other end of which is fixedly fitted with a flow-concentrating hood. The flow-concentrating hood is horn-shaped, and an air outlet plate is detachably installed on the inner side of the larger end of the flow-concentrating hood. The surface of the air outlet plate is provided with multiple air outlet holes, and a central column is fixed at the center of the surface of the air outlet plate facing the flow-concentrating hood. Multiple flow-dividing plates are provided on the outer side of the central column.

[0007] Preferably, the flow divider includes two vertical right-angled sides and an arc-shaped side. The two right-angled sides of the flow divider are fixed to the central column and the air outlet plate, respectively, and the arc-shaped side of the flow divider is attached to the inner wall of the flow-concentrating hood.

[0008] Preferably, the diverter plates are arranged in a circular array around the axis of the central column, and the air outlets are arranged in a circular array around the center of the air outlet plates.

[0009] Preferably, a flow-guiding ball head is fixed at the end of the central column near the air inlet pipe. The flow-guiding ball head is hemispherical, and the diameter of the ball head is the same as the diameter of the central column.

[0010] Preferably, the number of the diverter plates is twelve, and the included angle between adjacent diverter plates is fifteen degrees.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] A flow-guiding ball is fixed at the end of the central column near the air inlet pipe. The flow-guiding ball disperses the drying hot airflow to the space between adjacent flow dividers. The drying hot airflow is evenly distributed between the adjacent flow dividers and reaches the air outlet. Finally, the drying hot airflow enters the drying chamber from the air outlets that are evenly distributed on the air outlet and form a circular array around the center of the air outlet. This ensures that the drying hot airflow is evenly distributed in the drying chamber, improving drying efficiency. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] like Figure 1 and Figure 2 As shown, a structure for airflow guidance and exhaust includes an air inlet pipe 1. One end of the air inlet pipe 1 is detachably and fixedly connected to the air outlet of a fan. The other end of the air inlet pipe 1 is fixed with a flow-concentrating hood 2, which is trumpet-shaped. An air outlet plate 5 is detachably installed on the inner side of the larger end of the flow-concentrating hood 2. Multiple air outlet holes 6 are provided through the surface of the air outlet plate 5. A central column 3 is fixed at the center of the surface of the air outlet plate 5 facing the flow-concentrating hood 2. Multiple diverting plates 4 are provided on the outer side of the central column 3. The flow-concentrating hood 2 is used to collect the drying hot airflow in a concentrated manner, and the collected drying hot airflow is evenly transported into the drying room through the air outlet holes 6 evenly distributed in a circular array on the surface of the air outlet plate 5.

[0019] As a preferred technical solution in this embodiment, such as Figure 2 and Figure 3 As shown, the flow divider 4 includes two vertical right-angled sides and an arc-shaped side. The two right-angled sides of the flow divider 4 are fixed to the central column 3 and the air outlet plate 5, respectively. The arc-shaped side of the flow divider 4 is attached to the inner wall of the flow hood 2. The flow divider 4 connects the flow hood 2 and the central column 3, so that the airflow between adjacent flow dividers 4 will not interfere with each other.

[0020] In this embodiment, there are twelve diversion plates 4, and the included angle between adjacent diversion plates 4 is fifteen degrees. The diversion plates 4 are arranged in a circular array around the axis of the central column 3, and the air outlets 6 are arranged in a circular array around the center of the air outlet plate 5. The diversion plates 4 arranged in a circular array divide the space between the central column 3 and the flow-concentrating hood 2 into multiple areas with the same capacity. The evenly distributed air outlets 6 can ensure that the airflow enters the drying room evenly from between adjacent diversion plates 4.

[0021] A flow guide ball head 7 is fixed at the end of the central column 3 near the air inlet pipe 1. The flow guide ball head 7 is hemispherical, and the diameter of the flow guide ball head 7 is the same as the diameter of the central column 3. The hemispherical flow guide ball head 7 is used to disperse the airflow entering the air inlet pipe 1, so that the airflow enters the adjacent flow divider plates 4 evenly, ensuring that the drying hot airflow is evenly distributed.

[0022] Working principle: First, connect the fixed end of the air inlet pipe 1 to the airflow output end of the drying fan. Then, turn on the power and start the device. After the fan is powered on, it will transport the drying hot airflow. The drying hot airflow enters the air inlet pipe 1 and flows towards the concentrator hood 2. When the drying hot airflow reaches the inlet of the concentrator hood 2, it first contacts the guide ball head 7. The guide ball head 7 disperses and guides the drying hot airflow, so that the dispersed drying hot airflow enters between the adjacent diverter plates 4. At this time, the drying hot airflow is evenly distributed and flows between the adjacent diverter plates 4. The drying hot airflow finally reaches the air outlet plate 5. After reaching the air outlet plate 5, the drying hot airflow is prevented from flowing out of the concentrator hood 2 through the air outlet plate 5 and the air outlet holes 6 distributed in a circular array. The airflow is evenly introduced into the drying chamber through the evenly distributed air outlet holes 6, so that the heat distribution inside the drying chamber is uniform, improving the drying efficiency and drying effect.

[0023] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and alterations to these embodiments without departing from the principles and spirit of this utility model will still fall within the protection scope of this utility model.
