Abstract
Description
Technical Field
[0001] This utility model belongs to the field of ceramic drying technology, specifically relating to a multi-layer constant temperature drying oven. Background Technology
[0002] Ceramics are non-metallic materials made from inorganic non-metallic minerals such as clay through high-temperature sintering. They possess properties such as high hardness, high-temperature resistance, and corrosion resistance. They are widely used in daily life (tableware, bathroom fixtures), industrial manufacturing (electronic components, mechanical parts), and high-tech fields (aerospace, biomedicine), serving as an important material carrier for combining traditional craftsmanship with modern technology.
[0003] A known patent application with application number 202322931488.7 discloses a constant temperature oven comprising a chamber and a tray. The tray is disposed within the chamber. Multiple guide rails are vertically arranged on the inner wall of the chamber, spaced apart. Each guide rail has a slider, and each slider has a fastener on its side wall. Multiple sliders are arranged at intervals along the length of the same guide rail. The side wall of each slider has a slot for engaging the tray. This invention allows for easy adjustment of the spacing between trays, facilitating the placement of more items within the oven and improving the baking efficiency of the constant temperature oven.
[0004] However, the following problems were found in the implementation of the relevant technology: When rotating, the device adopts a side drying and blowing setting, but the material cannot rotate on its own inside, which causes the outward side and the inward side to not be dried at the same time. The drying speeds on both sides are different, which can easily cause the items to split.
[0005] Therefore, a multi-layer constant temperature oven is proposed to solve the above problems. Utility Model Content
[0006] This invention proposes a multi-layer constant temperature drying oven, which solves the problem in related technologies where, during rotation, the device uses a side drying and blowing setting, but the material inside cannot rotate on its own, resulting in the outward side and the inward side not being dried simultaneously, and the drying speeds on both sides being different, which can easily cause items to split.
[0007] The technical solution of this utility model is as follows: a multi-layer constant temperature drying oven, comprising...
[0008] Outer drum;

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0029] Example 1
[0030] Please see Figure 1 -4, a multi-layer constant temperature oven, comprising:
[0031] Outer bucket 1;
[0032] The support rod 3 is arranged inside the outer barrel 1 and the barrel cover 2 is rotatably connected to the outer barrel 1;
[0033] The inner part of the outer barrel 1 is provided with a limiting sleeve 8, and the top end of the support rod 3 is rotatably connected to the inner wall of the limiting sleeve 8;
[0034] The outer wall of the support rod 3 is provided with multiple sets of connecting rods 6, and each connecting rod 6 is provided with a clamping ring 7 at its end. The inner wall of the clamping ring 7 is fitted with a rotating placement plate 5.
[0035] The outer wall of the support rod 3 has multiple ventilation holes 4;
[0036] The support rod 3 is a hollow structure, and the limiting sleeve 8 is a pipe structure that is connected to the support rod 3.
[0037] Multiple friction rings 20 are arranged inside the support rod 3 of the outer barrel 1, and the position of the friction rings 20 is in contact with the rotating placement plate 5;
[0038] A blower 11 is provided at the top of the outer barrel 1. A connecting pipe 10 is provided at the output end of the blower 11. The connecting pipe 10 is connected to the support rod 3. A heating block 9 is provided on the outside of the connecting pipe 10 to heat the air output by the blower 11.
[0039] A drive motor 16 is provided at the bottom of the outer barrel 1. The output end of the drive motor 16 is fixedly connected to the support rod 3 and is used to drive the support rod 3 to rotate.
[0040] The bottom of the outer bucket 1 is provided with support legs 17, and both the bucket lid 2 and the outer wall of the outer bucket 1 are provided with fixing plates 18. Multiple fixing wrenches 19 are inserted into the inner wall of the fixing plates 18 for sealing the outer bucket 1 and the bucket lid 2.
[0041] The technical solution provided in this embodiment is as follows: In use, first rotate the lid 2 outward to open the lid 2, then place the item on the rotating placement plate 5, and then close the lid 2. After closing, rotate the fixing wrench 19 to seal and fix the outer barrel 1 and the lid 2. Start the drive motor 16 at the bottom of the outer barrel 1 to drive the support rod 3 to rotate. When rotating, the rotating placement plate 5 set on the inner wall of the clamping ring 7 comes into contact with the friction ring 20 on the inner wall of the outer barrel 1. Under the rotation of the support rod 3, the rotating placement plate 5 rotates, causing the item to rotate. At the same time as starting the drive motor 16, start the blower 11 and the heating block 9. The blower 11 injects air from the outer wall into the connecting pipe 10, and the airflow is injected into the inside of the support rod 3 through the connecting pipe 10 and heated by the heating block 9. The hot air inside the support rod 3 is output through the vent 4, causing air convection and temperature rise inside the outer barrel 1, thus drying the item.
[0042] Example 2
[0043] Based on Embodiment 1, in this embodiment: a parallel pipe 12 is provided on the outer wall of the outer tub 1, the input end of the parallel pipe 12 is connected to the inside of the outer tub 1, an air pump 13 is provided on the outer wall of the parallel pipe 12 to drive the air in the parallel pipe 12, and the output end of the parallel pipe 12 is connected to the connecting pipe 10.
[0044] The technical solution provided in this embodiment is as follows: When drying the items inside the outer drum 1, the air pump 13 is started. The air pump 13 extracts the internal air through the parallel pipe 12. The parallel setting can extract the air inside the outer drum 1 more quickly, and then re-inject it into the connecting pipe 10 for reheating and entry into the interior of the outer drum 1. By increasing the air flow and the extracted air having a certain temperature, the heating efficiency of the heating block 9 is higher.
[0045] Furthermore, a fixing sleeve 14 is provided at the inner bottom of the outer barrel 1, and a fixing block 15 is fitted inside the fixing sleeve 14. The fixing block 15 is fixedly connected to the bottom end of the support rod 3.
[0046] Specifically, by setting the fixing sleeve 14 and the fixing block 15, the stability of the support rod 3 during rotation can be increased, preventing the support rod 3 from shaking and causing the item to fall during movement.
[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
