Description

Technical Field

[0001] This utility model relates to the field of oven technology, and in particular to an oven that reduces energy consumption. Background Technology

[0002] Drying ovens, as widely used heat processing equipment, are core equipment in many industrial fields such as metallurgy, food, chemical, ceramics, textile, and electronic materials. They are mainly used for drying, curing, and heat treatment processes. However, traditional drying ovens have problems such as poor insulation performance and energy loss due to the direct emission of large amounts of high-temperature exhaust gas during dehumidification, resulting in low thermal energy utilization. Therefore, it is necessary to design a drying oven that reduces energy consumption.

[0003] To address this, patent CN220297624U discloses an oven comprising: an oven body; a switching frame that can enter and exit the oven body; several support layers stacked within the switching frame; several guide rails disposed within the oven body; and several pulleys fixedly mounted on the switching frame and corresponding to the guide rails. The pulleys, by embedding themselves into the corresponding guide rails, drive the switching frame to move along the guide rails. This utility model's independent, operable switching frame maximizes the use of the oven's internal space, thereby increasing the number of products that can undergo high-temperature secondary vulcanization simultaneously. It also eliminates the need to first place products on trays, then use a trolley to push the trays to the oven door, and finally place the trays one by one onto the internal racks. The fixed racks inside the oven are directly transformed into switchable, mobile racks, saving considerable unnecessary working time. Furthermore, the casters on the oven rack allow for easy movement, making product inspection more convenient.

[0004] Although the ovens described above can be easily moved during use, heat tends to dissipate outwards through the outer wall of the oven during operation, resulting in low thermal energy utilization. Therefore, it is necessary to design an oven that reduces energy consumption. Utility Model Content

[0005] The purpose of this invention is to provide an oven that reduces energy consumption, thereby solving the problem that heat in existing ovens easily dissipates outward through the outer wall of the oven, resulting in low thermal energy utilization.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an energy-saving oven, including a cabinet;

[0007] A rotating structure is fixed on the inner wall at the bottom of the box. An inner liner is provided at the top of the rotating structure. Hollow slots are provided on both sides of the top of the inner liner. A top cover is hinged to the top of the box.

[0008] An insulation structure is fixed to the outer wall of the box. The insulation structure includes an adhesive layer fixed to the outer wall of the box, an inner insulation layer fixed to the outer wall of the adhesive layer, an outer insulation layer fixed to the outer wall of the inner insulation layer, and protective blocks fixed to the outer walls of the box at both ends of the adhesive layer.

[0009] A protective structure is provided on the outside of the outer insulation layer.

[0010] Furthermore, a heating component is fixed on the inner wall of the box, and rock wool insulation cotton is installed inside the outer side of the box.

[0011] Furthermore, the rotating structure includes a drive motor, a drive shaft, a limiting ring, a turntable, and a base. The base is fixed to the inner wall of the bottom of the housing. The top of the base is rotatably connected to the turntable. A limiting ring is fixed at the edge of the top of the turntable. The drive motor is fixedly installed at the bottom of the housing, and the output end of the drive motor is fixed to the drive shaft.

[0012] Furthermore, the top end of the drive shaft passes through the housing and base and is fixedly connected to the bottom end of the turntable.

[0013] Furthermore, the heating assembly includes a heating box, a heating chamber, and a heating wire. The heating box is fixed to the inner wall of the box body, and a heating chamber is formed inside the heating box. A heating wire is fixedly installed inside the heating chamber.

[0014] Furthermore, the inner insulation layer is a rock wool layer, and the outer insulation layer is a glass wool layer.

[0015] Furthermore, the protective structure includes a top pressure ring, a fixing bolt, a stacked ring, and a bottom support ring. The bottom support ring is disposed on the outer wall of the bottom protective block of the box, and stacked rings are evenly disposed on the top of the bottom support ring. The top pressure ring is disposed on the outer wall of the top protective block of the box, and stacked rings penetrate the interior of both the top pressure ring and the bottom support ring.

[0016] Furthermore, one end of each fixing bolt extends into the interior of the protective block, and the overlapping rings are evenly distributed above the bottom support ring.

[0017] Furthermore, the inner wall of the bottom of the top pressure ring and the outer wall of the top of the stacked ring abut against each other, and the inner wall of the bottom of the stacked ring and the outer wall of the top of the bottom support ring abut against each other.

[0018] Furthermore, the central axis of the inner liner and the central axis of the turntable are collinear.

[0019] The present invention provides an energy-saving drying oven, the advantages of which are:

[0020] By incorporating an insulation structure, the inner and outer insulation layers form a double insulation layer, optimizing the insulation effect for different temperature ranges. The adhesive layer ensures that the insulation material is tightly bonded to the chamber, and the protective block enhances the edge sealing. The combination of the inner and outer insulation layers takes into account both high temperature resistance and moisture protection requirements, enabling the device to easily insulate the chamber and improving the working efficiency of this energy-saving oven during use.

[0021] By setting up a protective structure, the insulation structure is pressed and fixed to the outer wall of the box by the top pressure ring, the stacked ring and the bottom support ring, which prevents the insulation structure from loosening or falling off. The stacked ring can disperse the external mechanical stress and protect the integrity of the insulation structure. The modular design makes it easy to disassemble and repair the insulation structure. This device has the function of protecting the insulation structure and improves the durability of the energy-saving oven during use.

[0022] By incorporating a rotating structure, the inner chamber and materials are rotated via a turntable, avoiding localized overheating or uneven heating, thus improving drying efficiency. Uniform heating shortens drying time and reduces energy waste. A limiting ring fixes the position of the inner chamber, preventing it from shifting or sliding during rotation and heating. This device facilitates uniform heating of materials, enhancing the convenience and applicability of this energy-saving oven. Attached Figure Description

[0032] When the external power supply is connected, the drive motor 21 is started. After the drive motor 21 is started, it drives the turntable 24 to rotate on the base 25 through the drive shaft 22. The material is inside the inner liner 8. The inner liner 8 rotates synchronously with the turntable 24 and is heated evenly in all directions under the action of the heating component 3.
