Description

Technical Field

[0001] This utility model relates to the field of vacuum kiln technology, and more specifically, to a rapid cooling and pressure relief structure for a vacuum kiln. Background Technology

[0002] Vacuum furnaces are widely used in the production and experimentation of ceramics, metallurgy, electronics, glass, chemicals, machinery, refractory materials, new material development, special materials, and building materials. Vacuum furnaces require the introduction of protective gas throughout the heating, holding, and cooling processes. This is primarily to protect the internal insulation electrodes from oxidation due to moisture in the air. During operation, rapid cooling and pressure relief are necessary. Existing rapid cooling and pressure relief structures suffer from fixed water spray positions, resulting in uneven cooling effects across different areas. A suitable water spray adjustment mechanism is lacking. Furthermore, internal mechanisms are prone to malfunction after prolonged use, and a suitable rapid maintenance mechanism is missing. Additionally, the disassembly and assembly efficiency of the maintenance mechanism is low, and a suitable rapid disassembly and assembly mechanism is also lacking. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a rapid cooling and pressure relief structure for a vacuum kiln, which has the following beneficial effects:

[0015] 1. Through the design of the water guide seat, and by setting an adjusting rod driven by an adjusting motor and threadedly connected to the adjusting hole on the water guide seat, precise and automated adjustment of the position of the water guide seat within the cooling shell is achieved. This allows the spray position of the water spray pipe to be dynamically adjusted according to the cooling needs of different areas of the vacuum kiln body, achieving more uniform, efficient, or targeted cooling, significantly improving cooling efficiency, avoiding problems of local overheating or insufficient cooling, and optimizing the utilization rate of cooling water.

[0016] 2. The design of the inspection plates includes inspection slots on both sides of the upper surface of the cooling shell, equipped with removable inspection plates. This provides a convenient access for inspection and maintenance of internal components (such as water guide seats, water guide pipes, water spray pipes, guide rods, etc.). Operators can directly observe the internal condition, troubleshoot, or replace vulnerable parts through the open inspection slots without extensive disassembly of the main equipment. This greatly simplifies the maintenance process, shortens equipment downtime, reduces maintenance costs, and ensures long-term stable operation of the equipment.

[0017] 3. The U-shaped clamping plate, combined with the clamping rod on the maintenance plate and the threaded retaining ring, forms a highly efficient and reliable quick-locking mechanism. This structure eliminates the traditional multi-bolt fixing method; simply tightening or loosening the retaining ring achieves secure locking or quick disassembly of the maintenance plate. This design significantly simplifies the operation, allowing for manual operation without additional tools, greatly improving the convenience and efficiency of maintenance plate assembly and disassembly, and providing significant convenience for daily equipment maintenance.

[0036] In summary, the overall equipment is in use:

[0037] When in the cooling and depressurization state, the control device has a built-in control system that starts the pump body 12 and the regulating motor 19. The regulating motor 19 is fixedly installed on the cooling shell 2 by its own L-shaped plate. The pump body 12 draws water out of the cold water tank 10 through the suction pipe 13 and then delivers it to the water guide pipe 8 and the water guide seat 6 through the water delivery pipe 9. The water is then sprayed outward through multiple spray pipes 7 on the water guide seat 6 to achieve uniform water delivery and cooling at each position. The regulating motor 19 drives the regulating rod 17 to rotate. The regulating rod 17 and the regulating hole 18 are threaded together, and the guide rod 21 and the guide hole 22 cooperate to guide and realize the adjustment of the spray position, so as to facilitate uniform water delivery at each position. Water vapor is easily generated when water is delivered for cooling.

At the same time as the cold water is delivered, the heat dissipation valve 15 of the heat dissipation pipe 14 is opened to improve the internal heat dissipation effect.

[0038] When in maintenance mode, rotate the retaining ring 29. The retaining ring 29 and the retaining rod 28 are threaded together. After removing the retaining ring 29, the U-shaped retaining plate 27 can be disassembled. After removing the U-shaped retaining plate 27, the maintenance plate 24 can be disassembled for maintenance, and the internal parts can be inspected, which facilitates internal maintenance operations.

[0039] When the inspection plate 24 is in the installation state, after the inspection is completed, the positioning rod 25 of the inspection plate 24 is installed and positioned corresponding to the positioning hole 26 of the inspection slot 23. After the initial installation, the U-shaped clamping plate 27 is installed corresponding to the clamping rods 28 of the two inspection plates 24. The retaining ring 29 and the clamping rod 28 are threaded together to achieve installation and locking, which is convenient and quick to install and lock.
