[0027] It should be noted that the following detailed descriptions are all illustrative and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.
[0028] Embodiment 1
[0029] In a typical embodiment of the present application, a drying furnace for mechanical processing parts is provided, such as Figure 1-4 As shown, it includes a drying furnace main body 1, and an energy-saving mechanism 2 is arranged on the outer side of the drying furnace main body 1. The energy-saving mechanism 2 includes a rotating shaft 206, and the top end of the rotating shaft 206 passes through the drying furnace main body 1 and extends to the inside of the drying furnace main body 1; inside the drying furnace main body 1, the outer surface of the rotating shaft 206 is fixedly connected to multiple groups of cross plates 201, and the multiple groups of cross plates 201 are evenly arranged up and down. In this embodiment, four groups are evenly arranged up and down; each group of cross plates is a structure of two straight plates intersecting vertically, which can be made as a whole, or can be welded and connected to the rotating shaft respectively, and the rotating shaft passes through the center of the cross plate. The outer end of the cross plate 201 extends to the inner wall of the drying furnace, but a certain gap is left with the inner wall of the drying furnace to reduce friction and ensure the smooth rotation of the cross plate. The cross plate divides the drying furnace into four groups of fan-shaped areas, one of which is connected to the external space and is the furnace outer area, such as Figure 1-2 As shown, the two sides of the outer zone of the furnace are main vertical plates, which are integrally processed with the drying furnace body 1 to separate the interior of the drying furnace from the external space, and divide the drying furnace into the inner zone and the outer zone in the circumferential direction, which can avoid the heat loss inside the drying furnace. It is easy to understand that as the rotating shaft drives the cross plate to rotate, the four groups of fan-shaped areas will switch between the inner zone and the outer zone.
[0030] like Figure 1-3 As shown, each group of fan-shaped areas is provided with drying baskets 203 of corresponding shapes, and the drying baskets are fixedly connected to the cross plates by welding, bonding or bolting, so four drying baskets are fixed on each group of cross plates 201, and the drying baskets 203 are arranged in four layers up and down with the cross plates, and the parts to be dried are placed in the drying baskets. The bottom surface of each drying basket 203 is evenly provided with a plurality of identical through holes 204 to ensure that the drying basket spaces in the same vertical line are all connected, and the evaporated steam inside the drying basket below can flow upward to promote the heat circulation in the furnace.
[0031] A bearing 10 is arranged on the top of the rotating shaft 206 , the inner ring of the bearing 10 is connected to the outer circle of the rotating shaft 206 , and the outer ring is connected to the shaft hole opened on the top of the drying furnace body 1 , which can improve the rotation stability of the rotating shaft 206 .
[0032] like Figure 3 As shown, the main vertical plate is provided with four layers of rectangular openings 207 on the upper and lower sides, which can allow the cross plate to drive the drying basket to rotate freely in and out of the drying furnace. The rectangular opening 207 is adapted to the radius of the cross plate 201 and the drying basket 203, ensuring that when the shaft rotates, the cross plate and the drying basket can smoothly rotate through the opening. At the same time, when the rotation stops, when the cross plate and the drying basket are located in the rectangular opening, the gap between the cross plate and the rectangular opening is as small as possible to reduce the heat loss in the furnace. It should be pointed out that Figure 3For the sake of clarity, only part of the drying baskets between each set of cross plates and the main vertical plate on one side of the furnace outer area are shown, which does not represent the actual setting.
[0033] like Figure 1-2 As shown, the energy-saving mechanism 2 is arranged at the bottom of the drying furnace body 1, and the energy-saving mechanism 2 also includes a stepper motor 209, and the output end of the stepper motor 209 is fixedly connected to the rotating shaft 206, so that the rotating shaft 206 is driven by the stepper motor 209 and the rotation speed and frequency are controlled, so that the four groups of drying baskets 203 arranged between the cross plates 201 can be rotated in turn to the outer furnace area exposed on the outside of the drying furnace body 1, and stay for a set time for replacement of parts.
[0034] A vent pipe 5 is fixed at the top of the drying furnace body 1, and the vent pipe 5 is connected to the inside of the drying furnace body 1. By providing the vent pipe 5, the steam inside the drying furnace body 1 can be discharged through the vent pipe 5, thereby achieving a good auxiliary effect. A baffle 3 is clamped inside the vent pipe 5, and a handle 4 is fixedly connected to the upper surface of the baffle 3. By providing the handle 4 and the baffle 3, the baffle 3 can be pulled out through the handle 4, thereby facilitating the adjustment of the connection state of the vent pipe 5 with the outside world.
[0035] like Figure 2 As shown, the outer surface of the drying furnace body 1 is fixedly connected to a control box 202, the inner wall of the control box 202 is fixedly connected to a controller 205, the left side of the control box 202 is movably hinged with a movable door 7, the left side of the movable door 7 is fixedly connected to a pulling handle 6, and by providing the pulling handle 6 and the movable door 7, the movable door 7 can be opened by pulling the handle 6, so as to facilitate the operation of the controller 205 inside the control box 202; the controller 205 is electrically connected to the stepping motor 209 and the heating wire 208 respectively through wires.
[0036] like Figure 4 As shown, four support columns 9 are fixedly connected to the bottom end of the drying furnace body 1, and a contact pad 8 is fixedly connected to the bottom end of each support column 9. The surface area of the contact pad 8 is larger than that of the support column 9, so that the contact area between the device and the ground is increased through the contact pad 8, making the device stand more stably. In this embodiment, the contact pad is made of rubber material, which can increase the friction between the device and the ground, play an anti-skid role, and further ensure the stability of the drying furnace. In addition, the outer surfaces of two of the support columns 9 are fixedly connected to a fixed plate 11, and the stepper motor 209 is placed on the fixed plate 11, which makes full use of the bottom space of the drying furnace body 1 and makes the entire device have better integrity.
[0037] The working principle of the utility model is: when in use, firstly, the stepper motor 209, the heating wire 208 and the controller 205 are connected to the power supply respectively, and the device can be used normally after the power supply is connected. When working, the mechanical parts to be dried are placed in the drying basket 203 in the furnace outer area exposed outside the drying furnace body 1, and the stepper motor 209 is controlled to run, and the power generated by the stepper motor 209 when running is used to drive the rotating shaft 206 and the cross plate 201 fixed on the outer surface of the rotating shaft 206 to rotate, so that the drying basket 203 exposed outside and equipped with parts can be driven to pass through the rectangular opening 207 and move to the inside of the drying furnace body 1. At this time, with the rotation, another group of adjacent drying baskets 203 are exposed in the furnace outer area, and the mechanical parts to be dried are placed therein. Similarly, the mechanical parts to be dried are placed in the drying baskets in the four groups of areas formed by the cross plate 201 in sequence. At the same time, the controller 205 is used to control the operation of the heating wire 208 in the furnace. The heating wire 208 will generate a large amount of heat during operation, which can ensure that the inside of the drying furnace main body 1 maintains a high temperature to dry the mechanical parts to be dried, so that the mechanical parts in the drying basket in the furnace can be continuously heated during the rotation process until the group of drying baskets rotates to the exposed area outside the furnace, and the dried mechanical parts can be removed and the dried mechanical parts can be placed in the drying basket. This cycle is repeated, which effectively improves the efficiency of drying parts and does not require the drying furnace to be stopped for replacement; and in the process of taking and placing parts, there is no need to open the drying furnace main body 1, just turn out the required drying basket 203, and at the same time, the rectangular opening 207 is adapted to the size of the cross plate 201 and the drying basket 203, while ensuring smooth rotation, the gap formed is small, which can effectively avoid the loss of heat inside the drying furnace when taking out or putting in mechanical parts, and can improve the thermal efficiency of the drying furnace.
[0038] The above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. For those skilled in the art, the utility model may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
