Description

Technical Field

[0001] This invention relates to the field of oven technology, specifically to a waste heat recovery oven for testing the color fastness of fabric sweat stains. Background Technology

[0002] The oven generates heat by using an electric heating element driven by a power source. The heat is absorbed by the fabric to be tested and converted into thermal energy, which can quickly complete the drying and baking process required for the color fastness of perspiration, meeting the test requirements of high efficiency and stability.

[0003] Currently, conventional ovens used for testing color fastness to perspiration generally lack waste heat recovery mechanisms, resulting in significant heat loss and energy waste during testing. Furthermore, during the drying and high-temperature treatment of the fabric being tested, surface dyes, auxiliaries, and residual finishing agents release volatile harmful gases such as formaldehyde. Direct release of these gases into the environment not only causes air pollution but also negatively impacts the testing environment and the health of operators.

[0004] Therefore, it is necessary to provide a waste heat recovery drying oven for testing the color fastness of fabric sweat stains to solve the above problems. Summary of the Invention

[0005] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is that the existing ovens do not have a waste heat recovery structure, which will cause heat loss and energy waste in the oven.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0022] Reference Figure 1-3 A waste heat recovery drying oven for testing the color fastness of fabric sweat stains includes: a base plate 1; an outer shell 2 fixedly connected to the base plate 1; a reducer 3 fixedly connected to the outer shell 2; a drying assembly 4 fixedly connected to the base plate 1 for drying and heating materials; an inner shell 41 fixedly connected to the base plate 1; two turntables 42 rotatably connected to the side wall of the inner shell 41, the two turntables 42 being arranged parallel to each other, and one of the turntables 42 being fixedly connected to the output end of the reducer 3; a heating plate 43 fixedly connected to the bottom of the inner shell 41; and a connecting rod 44 fixedly connected to the bottom of the inner shell 41. The following components are connected between the two turntables 42: a carrying assembly 45, movably mounted on the connecting rod 44, for carrying the material to be processed; an anti-slip sleeve 451, fixedly connected to the outer circumferential surface of the connecting rod 44; a collar 452, rotatably connected to the anti-slip sleeve 451; a connecting plate 453, fixedly connected to the collar 452; a carrying plate 454, slidably connected to the connecting plate 453, with the two connecting plates 453 and the carrying plate 454 forming an isosceles triangle; and a conversion assembly 5, fixedly connected to the base plate 1, for converting and storing the heat within the drying assembly 4.

[0023] Reference Figure 1 , 4 5. Four parallel support columns 11 are fixedly installed on the base plate 1, and the four support columns 11 are evenly distributed at each corner of the base plate 1. Each support column 11 has an anti-slip plate 12 fixedly installed at its bottom end, and multiple anti-slip ridges 13 are fixedly installed on the lower end surface of the anti-slip plate 12. The support columns 11 installed on the base plate 1 provide support for the device body. By placing each support column 11 at each corner of the base plate 1, it is ensured that each support column 11 can be subjected to uniform force, avoiding damage to the support columns 11 due to uneven force after long-term use. The anti-slip plate 12 and the anti-slip ridges 13 installed on the bottom of the support column 11 increase the friction between the device and the ground, ensuring that the device can operate stably and safely.

[0024] Reference Figure 6-8 A protective door 21 is hinged to the outer casing 2, and a handle 22 is fixedly installed on the outer wall of the protective door 21. A heat-resistant pad is fitted on the handle 22. The protective door 21 on the outer casing 2 ensures that the device will not affect the external environment during operation. The handle 22 on the protective door 21 makes it convenient for staff to open and close the protective door 21. The heat-resistant pad on the handle 22 prevents staff from burning their skin during use.

[0025] Reference Figure 2-4 A vertical plate 4541 is fixedly installed on both ends of the horizontal plate 454. A circular shell 4542 is fixedly installed on the vertical plate 4541. A shaft 45421 is slidably installed inside the circular shell 4542. A circular plate 4543 that fits against the inner wall of the circular shell 4542 is fixedly installed on the outer circumference of the shaft 45421. A spring 4544 is fixedly installed between the circular plate 4543 and the circular shell 4542. A retaining ring 4545 is fixedly installed on the end of the connecting plate 453 near the plate 454. Through the circular shell 4542 installed on the vertical plate 4541, when the staff needs to replace the plate 454, the staff can manually move the shaft 45421 so that the shaft 45421 disengages from the retaining ring 4545. Then, the staff can release the shaft 45421 so that the shaft 45421 returns to its original shape under the action of the spring 4544.

[0026] Reference Figure 1-3 The three load-bearing components 45 are spaced at the same distance, and the load-bearing plate 454 remains vertically downward in its natural state. By setting the positional relationship between the three load-bearing plates 454, it is ensured that the load-bearing plates 454 will not collide during use.

[0027] Reference Figure 3-5The conversion component 5 includes a liquid storage cylinder 51 fixedly mounted on the base plate 1. The liquid storage cylinder 51 is connected to the inner shell 41 via a gas supply pipe 52. A blower 53 for conveying hot gas flow is fixedly mounted on the inner shell 41. Through the liquid storage cylinder 51 mounted on the base plate 1 and the gas supply pipe 52 connecting the liquid storage cylinder 51 and the inner shell 41, the blower 53 can transfer excess heat to the liquid storage cylinder 51 for conversion and storage during device operation. Furthermore, since the liquid storage cylinder 51 only has an outlet at the connection between its upper end face and the long plate 67, the hot gas flow delivered by the gas supply pipe 52 can heat the solution in the liquid storage cylinder 51 for a long time.

[0028] Reference Figure 5-7 A stirring frame 511 is slidably arranged inside the liquid storage cylinder 51, and a stirring shaft 512 is rotatably arranged between the stirring frames 511. A transmission component 6 is provided on the inner shell 41 to control the up and down movement of the stirring frame 511. By using the stirring frame 511 arranged inside the liquid storage cylinder 51, the mixing degree between the purified liquid and the gas is achieved, thereby improving the purification efficiency of the solution.

[0029] Reference Figure 3-5 The transmission assembly 6 includes a disc 61 fixedly connected to the turntable 42. A limiting post 62 is fixedly installed at an eccentric position on the disc 61. A bracket 63 is fixedly installed on the base plate 1. A sliding groove 64 is opened on the bracket 63. A slider 65 is slidably installed on the sliding groove 64. A limiting frame 66 is fixedly installed in the horizontal direction of the slider 65. The limiting frame 66 is slidably connected to the limiting post 62. The other end of the slider 65 is fixedly connected to the stirring frame 511 through a long plate 67. When the turntable 42 rotates, the disc 61 fixedly connected to the turntable 42 rotates, thereby driving the limiting post 62 to make an eccentric movement. The moving limiting post 62 drives the slider 65 inside it to make up-and-down reciprocating operation through the limiting frame 66, and then drives the stirring frame 511 to make up-and-down reciprocating operation through the long plate 67, thereby improving the stirring efficiency.

[0030] Reference Figure 6-8 A toothed plate 7 is fixedly connected to the side wall of the storage cylinder 51, and a gear 71 that meshes with the toothed plate 7 is fixedly provided on the outer circumferential surface of the stirring shaft 512. During the movement of the stirring frame 511, the toothed plate 7 fixedly provided on the side wall of the storage cylinder 51 drives the gear 71 to rotate, thereby driving the stirring shaft 512 to rotate and stir the solution.

[0031] Reference Figure 6-8 Multiple stirring rods 5121 are fixedly installed on the outer circumferential surface of the stirring shaft 512, and the multiple stirring rods 5121 are evenly distributed among them. When the stirring shaft 512 rotates, the stirring rods 5121 fixedly installed on its outer circumferential surface rotate and stir the solution, thereby improving the working efficiency of the device.

[0032] The specific steps of this solution are as follows: When using the device, the operator first moves it to a suitable position. The support columns 11 on the base plate 1 provide support for the device body. Furthermore, by placing each support column 11 at a corner of the base plate 1, the operator ensures that the support columns 11 are evenly stressed, preventing damage caused by uneven stress after prolonged use. The anti-slip plates 12 and anti-slip ridges 13 on the bottom of the support columns 11 increase the friction between the device and the ground, ensuring stable and safe operation. The operator then places the workpiece to be processed onto the device's loading platform. The starting device on 454, the reducer 3 drives the turntable 42 to rotate and heat the material. When the turntable 42 rotates, the disc 61 fixedly connected to the turntable 42 rotates, thereby driving the limiting column 62 to make an eccentric movement. The moving limiting column 62 drives the slider 65 inside it through the limiting frame 66 to make up and down reciprocating operation. Then, through the long plate 67, it drives the stirring frame 511 to make up and down reciprocating operation, improving the stirring efficiency. Through the liquid storage cylinder 51 set on the bottom plate 1 and the air supply pipe 52 connected between the liquid storage cylinder 51 and the inner shell 41, the exhaust fan 53 can transfer excess heat to the liquid storage cylinder 51 for conversion and storage when the device is operating.
