Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying equipment technology, and in particular to a DC motor drying oven. Background Technology
[0002] A DC motor is a rotary electric machine that converts direct current (DC) electrical energy into mechanical energy (DC motor) or mechanical energy into DC electrical energy (DC generator). It is a motor capable of converting between DC electrical energy and mechanical energy. In the production process of a DC motor, the wound coil needs to be impregnated with insulating varnish. After impregnation, heating is necessary to remove the solvent from the varnish and any moisture that may be present inside the coil / insulation material. More importantly, it is crucial to cure the insulating varnish, forming a strong and dense insulating layer. In existing drying ovens, the items to be dried are typically placed on racks inside the oven. The items remain stationary throughout the process, allowing only one side of the item to be dried, resulting in poor drying uniformity and low drying efficiency. Utility Model Content
[0003] To address the shortcomings of existing technologies, this invention provides a DC motor drying oven, which solves the problem of poor drying uniformity and low drying efficiency.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The drying furnace body is provided with a furnace door at the front, the hot air dryer is located above the drying furnace body and communicates with the interior of the drying furnace body, and an exhaust port is provided at the bottom of the drying furnace body.
[0007] The drying box is installed inside the drying furnace. Rotating rods are fixedly connected to both sides of the drying box. The two rotating rods are coaxially arranged and are rotatably connected to the inner wall of the drying furnace along the axis of the rotating rod.
[0008] The drying oven includes a box body and a door. The box body is provided with several ventilation holes, and several partitions are arranged at intervals along the horizontal direction inside the box body. The two sides of the partitions are set as arc surfaces that are inclined from the center to the surrounding area.
[0009] Preferably, inclined air guide plates are provided at the top of the drying oven body and on both sides of the drying box.
[0010] Preferably, a motor is also provided, in which a rotating rod extends out of the drying oven body and is coaxially fixedly connected to a transmission wheel. The output end of the motor is also coaxially fixedly connected to a transmission wheel, and a transmission belt is used to drive the two transmission wheels.
[0011] Preferably, the partition is perpendicular to the rotating rod.
[0012] Preferably, the door includes a door frame and a mesh panel, with the mesh panel fixed inside the door frame.
[0013] Preferably, one end of the door frame is hinged to one side of the box body, and the other end is provided with a through hole. The other end of the box body is provided with a threaded hole and a bolt is also provided. The bolt's screw can pass through the through hole and be threaded into the threaded hole.
[0014] This utility model has the following beneficial effects:

[0021] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.
[0022] Please see Figures 1 to 3As shown, a DC motor drying oven includes: a drying oven body 1, a hot air dryer 2, and a drying chamber; the drying oven body 1 is provided with an oven door at the front, the hot air dryer 2 is provided above the drying oven body 1 and communicates with the interior of the drying oven body 1, and an exhaust port 11 is provided at the bottom of the drying oven body 1; the drying chamber is provided inside the drying oven body 1, and rotating rods 3 are fixedly connected to opposite sides of the drying chamber, the two rotating rods 3 are coaxially arranged, and the rotating rods 3 are rotatably connected to the inner wall of the drying oven body 1 along the axis of the rotating rods 3; the drying chamber includes a chamber body 4 and a chamber door 5, the chamber body 4 is provided with a plurality of ventilation holes 41, and a plurality of partitions 6 are arranged at intervals along the horizontal direction inside the chamber body 4, the two sides of the partitions 6 are set as arc surfaces inclined from the center to the surrounding area.
[0023] The structure of the hot air dryer 2 can be referenced from existing technology and will not be described here. The hot air dryer 2 delivers hot air into the drying oven body 1 to dry the items inside, such as small DC motors. Specifically, the hot air dryer 2 is positioned directly above the drying oven body 1. The oven door is not shown in the figure. An exhaust port 11 is located at the bottom of the drying oven body 1, and a filter screen is installed inside the exhaust port 11 to expel air. Ventilation holes 41 are provided on the drying chamber, through which hot air enters the drying chamber. The two rotating rods 3 are coaxially arranged, facilitating the rotation of the drying chamber by the rotating rods 3, allowing the items inside the drying chamber to rotate and be dried on multiple sides. Multiple partitions 6 are provided to separate multiple items, and the sides of the partitions 6 are curved surfaces sloping outwards from the center. The center of the partition 6 contacts the items, and the contact area between the partition 6 and the items is small, facilitating drying of the side closest to the partition 6. This device can dry multiple sides of items, improving drying efficiency.
[0024] Furthermore, such as Figure 1 As shown, inclined air guide plates 7 are provided at the top of the drying oven body 1 and on both sides of the drying chamber. The inclined air guide plates 7 change the direction of the hot air blown out from the hot air dryer 2, so that the hot air is concentrated to dry the items in the drying chamber.
[0025] Furthermore, such as Figure 1 As shown, a motor 8 is also provided, with one of its rotating rods 3 extending out of the drying oven body 1 and coaxially fixedly connected to a transmission wheel. The output end of the motor 8 is also coaxially fixedly connected to a transmission wheel, and a transmission belt 9 is connected between the two transmission wheels. The rotating rod 3 is driven to rotate by the motor 8.
[0026] Furthermore, such as Figures 1 to 3 As shown, the partition 6 is perpendicular to the rotating rod 3, allowing items inside the drying oven to be dried simultaneously.
[0027] Furthermore, such as Figure 2As shown, the door 5 includes a door frame 51 and a mesh panel 52, with the mesh panel 52 fixed inside the door frame 51. The mesh panel 52 has several holes, allowing hot air to enter the drying chamber through these holes, thus improving drying efficiency.
[0028] Furthermore, such as Figure 1 and Figure 2 As shown, one end of the door frame 51 is hinged to one side of the box body 4, and the other end is provided with a through hole 511. The other end of the box body 4 is correspondingly provided with a threaded hole 42 and a bolt is also provided. The bolt's shank can pass through the through hole 511 and be threaded into the threaded hole 42. Tightening the bolt will open the box door 5, making it easy to place or take out items.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
