[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1 As shown, the utility model provides a kiln for producing glass fiber yarn, including a kiln body 1, a foot pad 2, an inner furnace door 3, an outer furnace door 4, a combined device 5, a combustion-supporting device 6, a cooling heat recovery device 7 and a temperature measuring device 8, wherein the foot pad 2 is arranged at the bottom of the kiln body 1, and there are 4 of them. The foot pads 2 are evenly distributed at the four corners of the kiln body 1 to improve the structural stability of the kiln body 1; the combined device 5 is arranged between the inner furnace door 3 and the outer furnace door 4, and the combined device 5 is used to connect the inner furnace door 3 and the outer furnace door 4, the outer furnace door 4 is arranged on the outer wall of the kiln body 1, and the inner furnace door 3 is arranged on the inner wall of the kiln body, the inner wall of the outer furnace door 4 and the outer wall of the inner furnace door 3 are adapted through the combined device 5, and the combined device 5 includes a groove 51 and a protrusion 52, the groove 51 is fixed to the outer surface of the inner furnace door 3, and the protrusion 52 is fixed to the inner surface of the outer furnace door 4. When the outer furnace door 4 slides open, it drives the protrusion 52 to slide in the groove 51. As the outer furnace door 4 opens, the protrusion 52 slides from one end of the groove 51 to the other end. When the protrusion 52 contacts the other end of the groove 51, the outer furnace door 4 will drive the inner furnace door 3 to open, shortening the operation steps and reducing the risk of manual operation.

[0025] The combustion-supporting device 6 is disposed on the outer wall of the kiln body 1 and includes an air inlet pipe 61, a natural gas inlet pipe 62, and an exhaust gas outlet pipe 63. The exhaust gas outlet pipe 63 is sleeved on the outside of the air inlet pipe 61, and the natural gas inlet pipe 62 is located above the exhaust gas outlet pipe 63. The air inlet pipe 61, the natural gas inlet pipe 62, and the exhaust gas outlet pipe 63 all pass through the outer wall of the kiln body 1 and communicate with the inner cavity of the kiln body 1. The exhaust gas outlet pipe 63 is sleeved on the outside of the air inlet pipe 61. When the exhaust gas in the kiln body 1 is discharged, the heat brought out will preheat the air in the air inlet pipe 61, allowing the air and the natural gas in the natural gas inlet pipe 62 to burn more quickly and fully in the kiln body 1.

[0026] The cooling heat recovery device 7 is arranged on the outer surface of the kiln body 1. The cooling heat recovery device 7 includes a cooling box 71, a cooling pipe 72, an insulation layer 73, a water outlet 74, and a water inlet 75. The cooling box 71 is arranged on the lower surface of the kiln body 1. A condenser is provided in the cooling box 71. The insulation layer 73 is arranged on the outer surface of the kiln body 1. The cooling pipe 72 is arranged between the insulation layer 73 and the kiln body 1. The cooling pipe 72 is connected to the cooling box 71, and the water outlet 74 is connected to the water inlet 75. The condenser in the cooling box 71 is used to cool the refrigerant circulating in the refrigerant pipe 72. The design of the water outlet 74 and the water inlet 75 can discharge the refrigerant in the refrigerant pipe 72 and the cooling box 71 that has absorbed heat and use it as raw material for the heat recovery device, thereby increasing material utilization and energy-saving cycle efficiency.

[0027] The temperature measuring device 8 is arranged on the upper surface of the kiln body 1; the temperature measuring device 8 includes an electronic thermometer 81 and a display screen 82. One end of the electronic thermometer 81 is connected to the upper surface of the kiln body 1, and the display screen 82 is arranged above the electronic thermometer 81. The electronic thermometer 81 is electrically connected to the display screen 82. The display screen 82 is used to display the temperature of the kiln body 1 monitored by the electronic thermometer 81, so that the operator can more intuitively record and control the temperature inside the kiln body 1.

[0028] Working Principle: During use, hold the handle on the outer furnace door 4 to open it. As the outer furnace door 4 slides outward, the combined device 5 drives the inner furnace door 3 to open, and the raw materials are then placed into the internal cavity of the kiln body 1. This simplifies the operation steps and reduces operational risks. Close the inner and outer furnace doors 3 and 4. Then, the combustion-supporting device 6 allows the raw materials in the kiln body 1 to burn and melt more fully. The external cooling and heat recovery device 7 can also promptly cool the kiln body 1 after the raw materials are melted, and the absorbed heat can be used for recycling, thereby achieving a higher recycling rate.

[0029] Therefore, the use of the above-mentioned kiln for producing glass fiber yarn simplifies the operating steps, reduces the operating risks, and cools the kiln in time, so that the absorbed heat can be used for recycling and processing, thereby increasing the recycling rate.

[0030] This document uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
