Description

Technical Field

[0001] This utility model belongs to the technical field of heat treatment boxes, specifically a ceramic heat treatment box for the surface of cookware spraying lines. Background Technology

[0002] With the continuous development of modern kitchen utensils, consumers have put forward higher requirements for the performance and appearance of cookware. Cookware not only needs to have excellent corrosion resistance, wear resistance and high temperature resistance, but also needs to have a beautiful and easy-to-clean surface. In order to meet these needs, the cookware manufacturing industry has gradually introduced surface ceramicization technology. Surface ceramicization is a technology that coats a ceramic coating on the surface of a metal substrate and performs high-temperature heat treatment to form a composite coating with ceramic properties. It can significantly improve the surface hardness and heat resistance of cookware, while giving it excellent chemical corrosion resistance and anti-adhesion properties. The heat treatment process, through high-temperature sintering, enables the ceramic particles in the coating to form a strong bond with the metal substrate, while eliminating pores and defects inside the coating and improving the density and uniformity of the coating.

[0003] The existing ceramic heat treatment boxes for cookware coating lines have the following main shortcomings:

[0004] The existing ceramic heat treatment chamber on the cookware spraying line is prone to uneven temperature distribution, with some areas having high temperatures and others low temperatures. This results in different degrees of ceramicization in the cookware, leading to inconsistent product performance. Some cookware has a ceramic coating with high hardness while others have low hardness, affecting product quality and yield. As working time increases, dust and impurities in the air easily adhere to the cookware surface, affecting the ceramicization effect and causing defects on the ceramic coating surface. It also has poor adaptability to cookware of different shapes and sizes. For cookware with special shapes, it is difficult to fix and place them well, resulting in uneven heating and affecting the ceramicization effect. Utility Model Content

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] like Figures 1-4 As shown, the present invention provides the following technical solution:

[0024] The cookware spray coating line surface ceramicizing heat treatment box includes:

[0025] The box body 1 has a first heating structure 2 fitted on its inner side wall. Air inlet and exhaust structures 3 are provided at the upper center of one side wall and the lower center of the other side wall. A second heating structure 4 is provided at the center of the first heating structure 2. The first heating structure 2 includes an insulation layer 201, which is fitted on the inner side wall of the box body 1. A placement box 204 is provided at the center of the insulation layer 201. A cavity 202 is provided between the insulation layer 201 and the placement box 204. Electric heating tubes 203 are provided at the center of the cavity 202 on both sides, front and back. The insulation layer 201 provides insulation and reduces heat loss. When the electric heating tubes 203 are energized, they generate heat to heat the cavity 202, bringing the inside of the box to the appropriate temperature required for ceramic heat treatment. The heat is then transferred to the placement box 204, which in turn heats the cookware placed on the second heating structure 4.

[0026] The two air intake and exhaust structures 3 include an air intake frame 301, which is located at the upper center of one side wall of the housing 1. Two sliding boxes 302 are arranged horizontally at the center of the air intake frame 301 on one side. A filter screen 303 is located at the center of the sliding box 302 on one side. An absorbent cotton 304 is located on one side of the filter screen 303 and inside the sliding box 302. An exhaust frame 306 is located at the lower center of the other side wall of the housing 1. One end of each of the two sliding boxes 302 passes through the upper inner wall of the air intake frame 301 and extends to the upper end face of the air intake frame 301. An air intake fan 305 is located at the center of the air intake frame 301 on the other side. An exhaust fan 307 is located at the center of the exhaust frame 306.

[0027] Outside air is drawn in by the intake fan 305 inside the intake frame 301. The air first passes through the filter 303 inside the sliding box 302 on one side, which filters out larger dust particles and other impurities. Then the air passes through the absorbent cotton 304, which further absorbs fine particles and moisture, making the air entering the cavity 202 cleaner. After entering the cavity 202, the clean air is heated by the electric heating tube 203, and the air flows inside the cavity 202. The exhaust fan 307 inside the exhaust frame 306 exhausts the heated air from the cavity 202 outside the box. In this way, the air enters from the intake frame 301 and exits from the exhaust frame 306, forming a circulation inside the cavity 202. This air circulation makes the temperature distribution more uniform in different positions of the placement box 204, avoiding local overheating or underheating, which is conducive to the uniform ceramic heat treatment.

[0028] The second heating structure 4 includes a base 401, which is located at the lower center of the placement box 204. Multiple support rods 402 are arranged in a ring on the end face of the base 401. A retaining ring 403 is located at the center of the upper end face of each support rod 402. Multiple hooks 404 are arranged in a ring on the upper center of the inner side wall of the retaining ring 403. A placement rack 407 is located at the center of the upper end face of the retaining ring 403. Placement plates 408 are located at both the upper and lower center of the interior of the placement rack 407. The upper end face of the retaining ring 403 is arranged in a ring... Four locking blocks 405 are provided. The lower end face of the placement frame 407 is provided with four locking slots 406 arranged in a ring. The four locking slots 406 are respectively adapted to the four locking blocks 405. The upper end face of the placement frame 407 is provided with four lifting hooks 409 arranged in a ring. The outer wall of the placement frame 407 is provided with four bolts arranged in a ring. One end of the four bolts passes through one side wall of the four locking slots 406 and one side wall of the four locking blocks 405 respectively and leads to the inside of the four locking blocks 405. The ends are all threaded and rotatably connected to the inside of the four locking blocks 405.

[0029] The cookware to be processed can be placed on the rack 407 of the second heating structure 4. The rack 408 inside the rack 407 can support the cookware. Furthermore, small parts can be hung or the cookware can be further secured by the hook 404 on the snap ring 403. The snap ring 403 and the rack 407 are engaged by the snap block 405 and the snap groove 406 and secured with bolts to ensure that the rack 407 is installed securely. The lifting hook 409 on the rack 407 facilitates the hoisting and retrieval of cookware by the staff.

[0030] The working principle of this utility model is as follows: the cookware to be processed can be placed on the placement rack 407 of the second heating structure 4. The placement plate 408 inside the placement rack 407 can support the cookware. Furthermore, small parts can be suspended or the cookware can be further fixed by the hook 404 on the retaining ring 403. The retaining ring 403 and the placement rack 407 are engaged by the retaining block 405 and the retaining groove 406 and fixed with bolts to ensure that the placement rack 407 is installed firmly. The lifting hook 409 on the placement rack 407 facilitates the hoisting and retrieval of the cookware by the staff. After the cookware is placed inside the box 1, the heat loss to the outside is reduced by the heat insulation layer 201 to maintain the stable temperature inside the box. The electric heating tube 203 uses the thermal effect of the current to convert electrical energy into heat energy, which raises the temperature of the air in the cavity 202 and can be transferred to the placement box 204, thereby creating a suitable high-temperature environment for the ceramic heat treatment of the cookware.

[0031] Air circulation is achieved through the coordinated operation of the air intake and exhaust structure 3. The intake fan 305 generates suction, drawing outside air into the intake frame 301. The air first passes through the filter 303 within the sliding box 302, removing larger dust particles and impurities. Then, it passes through the absorbent cotton 304, which further absorbs fine particles and moisture, resulting in clean air that enters the cavity 202. In the cavity 202, the clean air is heated by the electric heating element 203. The heated air then flows naturally within the cavity 202. Simultaneously, the exhaust fan 307 draws the hot air out... The exhaust rack 306 discharges air outside the box, thus forming a continuous and stable air circulation flow, making the temperature around the placement box 204 more uniform, eliminating local temperature differences, and ensuring the consistency of heat treatment effect. When the cookware reaches the predetermined ceramic heat treatment time and temperature, the electric heating tube 203 is turned off, and the air intake fan 305 and exhaust fan 307 continue to run for a period of time to gradually reduce the temperature inside the box. At the same time, the residual high-temperature exhaust gas is discharged from the box 1. The processed cookware is lifted out of the placement rack 407 by using the lifting hook 409 to complete the unloading process.

[0032] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
