Description

Technical Field

[0001] This utility model relates to the field of drying oven technology, and in particular to a hot air drying oven. Background Technology

[0002] With the improvement of living standards and production technology, users have more and more demand for product customization, especially when drying small batches of workpieces. Large drying equipment consumes a lot of energy and can only play its greatest role in mass production lines. Small drying boxes have a small capacity and can only dry one or two workpieces at a time, resulting in low work efficiency. Therefore, it is necessary to design a drying device that can adapt to small batch production under complex conditions to meet the growing demand for flexible manufacturing. Utility Model Content

[0003] In view of this, the purpose of this utility model is to address the shortcomings of the existing technology by providing a hot air drying oven whose capacity can be adjusted according to the number of workpieces, thereby improving the level of flexible manufacturing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A hot air drying oven includes a box body, multiple drying racks, and multiple baffles. An air inlet is opened at the top of the box body and connected to a hot air blower. An air outlet is opened at the bottom of the box body. Multiple partitions are installed inside the box body to divide the interior of the box body into multiple vertical channels. The drying racks slide into each channel from the side of the box body. A sealing plate is provided at the front end of the drying rack. The baffles slide into the top and bottom of each channel from the side of the box body and can block the channel.

[0006] Furthermore, the baffle is a heat insulation board.

[0007] Furthermore, handles are provided on both the baffle and the sealing plate.

[0008] Furthermore, the drying rack has a rectangular frame structure.

[0009] The beneficial effects of this utility model are:

[0010] This invention divides the interior of the drying oven into multiple channels. During use, only some channels need to be opened for hot air circulation based on the number of workpieces, while the remaining channels are blocked with baffles, thus reducing energy loss.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0016] Reference Figures 1-3 The hot air drying oven provided by this utility model includes a box body 1, multiple drying racks 2, and multiple baffles 3. An air inlet is opened at the top of the box body 1, and a hot air blower is connected to the air inlet (the specific structure of the hot air blower is not shown in the attached drawings for ease of observation of the internal structure of the box body 1). An air outlet is opened at the bottom of the box body 1. Hot air first enters the interior of the box body 1 through the air inlet and then exits through the air outlet at the bottom. The drying racks 2 have a rectangular frame structure, which is structurally stable. Suspending the workpiece in the middle of the rectangular frame avoids contact with the inside of the box body 1.

[0017] Multiple partitions 4 divide the interior of the chamber 1 into several vertical channels 101. Each individual channel 101 is used to hold a workpiece to be dried. A drying rack 2 slides into each channel 101 from the side of the chamber 1, suspending the workpiece on the rack. The workpiece is moved into or out of the chamber 1 by pulling the rack 2. A sealing plate 5 is provided at the front end of the drying rack 2 to seal the end of the rack 2 to the side opening of the chamber 1. Baffles 3 slide into the top and bottom of each channel 101 from the side of the chamber 1, and can block the channel 101. The opening and closing of each channel 101 and the air intake can be adjusted by pulling the baffles 3. Because each channel 101 is ventilated independently, workpieces with different drying times can be dried simultaneously. The removal and placement of workpieces does not affect the workpieces in other channels 101, thus broadening its application range.

[0018] The baffle 3 is a heat insulation plate, which can prevent excess heat leakage after sealing the channel 101. Both the baffle 3 and the sealing plate 5 are equipped with handles 6 for easy pulling out of the baffle and the sealing plate.

[0019] In use, pull out the drying rack 2, suspend the workpiece to be dried in the middle of the drying rack 2, and then send the drying rack 2 into the channel 101 of the box 1. Pull out the upper and lower baffles 3 in the channel 101 where there are workpieces, and adjust the pulling length of the baffles 3 according to the air intake requirements to ensure that the upper and lower baffles 3 in the channel 101 where there are no workpieces block the channel 101. Then start the hot air blower, and hot air enters the channel 101 from the air inlet of the box 1 to dry the workpieces inside.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
