[0002] Insulators are special insulating components, typically made of glass, ceramic, or composite materials. They play a crucial role in overhead transmission lines, substations, and electrical equipment. The firing process of insulators is a key factor determining their final performance, and precise temperature control is paramount. Currently, boilers for insulator firing with temperature regulation functions, by incorporating advanced temperature sensors, intelligent controllers, and efficient heating and cooling systems, can adjust the boiler temperature in real time and precisely according to a preset temperature curve, effectively improving the firing quality and production efficiency of insulators.

[0003] However, during the operation of existing boilers, due to the physical characteristics of rising hot air, heat tends to accumulate in the top area of ​​the boiler. The temperature in this area is often higher than in other parts, resulting in uneven heating of the insulators during firing. In addition, existing boilers generally lack effective heat recovery mechanisms, making it impossible to make reasonable use of the heat accumulated at the top, resulting in a great waste of energy and increased production costs. Therefore, we need to propose a boiler for insulator firing with temperature control function. Utility Model Content

By setting a temperature control module and heating wire, precise temperature control is achieved. Heat is recovered by configuring a circulation component and insulation material, and gas is purified by using a collection component. This achieves the effect of ensuring the firing quality of insulators and reducing energy consumption, thereby solving the problems mentioned in the background art.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A boiler for firing insulators with temperature control function includes: a furnace body 1, in which heating wires 2 are fixedly installed; a temperature control module 3 is fixedly installed on the outer wall of the furnace body 1; the heating wires 2 are electrically connected to the temperature control module 3; the furnace body 1 serves as the main container for the entire firing process, providing a firing space for the insulators; the heating wires 2 are evenly distributed inside the furnace body 1, which can quickly and evenly generate heat to meet the temperature conditions required for firing the insulators; the temperature control module 3 has high-precision temperature detection and control functions; through its electrical connection with the heating wires 2, it can regulate the temperature inside the furnace body 1 in real time, and automatically adjust the power of the heating wires 2 according to a preset temperature curve to ensure that the temperature inside the furnace body 1 is always within a suitable range for firing insulators; by setting the precise coordination between the temperature control module 3 and the heating wires 2, the effect of precise control of the furnace temperature is achieved, effectively improving the stability and consistency of the firing quality of the insulators;

[0027] The exhaust pipe 4 is fixedly connected to the outer wall of the furnace body 1, and the bottom of the furnace body 1 is fixedly connected to the inlet pipe 5. A circulation component 6 for heat recovery and utilization is set between the exhaust pipe 4 and the inlet pipe 5. The exhaust pipe 4 allows the hot air at the top of the furnace body 1 to be discharged smoothly, avoiding the accumulation of heat at the top. The inlet pipe 5 provides a channel for the circulating gas to enter the furnace body 1. The function of the circulation component 6 is to recover the hot air discharged from the exhaust pipe 4 and send it back into the inlet pipe 5 to realize the recycling of heat. By setting the exhaust pipe 4, the inlet pipe 5 and the circulation component 6, the excess heat at the top of the furnace is recovered and utilized, and the energy consumption is reduced. At the same time, it also helps to maintain the uniformity of the furnace temperature.

[0028] The housing 7 is electrically connected to the circulation assembly 6. Inside the housing 7 is a collection assembly 8 for filtering impurities in the circulating gas. The circulation assembly 6 includes a first connecting pipe 601, the top end of which is fixedly connected to the outlet pipe 4, and the bottom end of which is fixedly connected to the housing 7. A pump body 602 is fixedly connected to the top of the housing 7, and a second connecting pipe 603 is fixedly connected to the top of the pump body 602. One end of the second connecting pipe 603 is fixedly connected to the bottom end of the inlet pipe 5. The first connecting pipe 601 guides the hot air discharged from the outlet pipe 4 into the housing 7. The pump body 602, as a power source, generates sufficient pressure to transport the gas inside the housing 7 to the inlet pipe 5 through the second connecting pipe 603, allowing the hot air to re-enter the interior of the furnace body 1. By configuring the circulation assembly 6, consisting of the first connecting pipe 601, the pump body 602, and the second connecting pipe 603, efficient gas transportation and heat recovery are achieved, improving energy efficiency.

[0029] The outer walls of both the first connecting pipe 601 and the second connecting pipe 603 are covered with insulation material. The insulation material can effectively reduce the heat loss of hot air during the transmission process and ensure that the circulating gas maintains a high temperature when it enters the furnace body 1. This achieves the effect of reducing heat transmission loss and improving heat recovery and utilization rate, and further enhances the energy-saving performance of the boiler.

[0030] The insulation material is aluminum silicate fiber cotton, which is a fibrous insulation material made from hard clay clinker as raw material, melted in an electric resistance furnace, sprayed or spun into fibers. Aluminum silicate fiber cotton has a low thermal conductivity, which can effectively reduce the heat loss of hot air during transmission and ensure that the circulating gas maintains a high temperature when entering the furnace body 1. Its insulation effect is particularly outstanding in high-temperature environments, which can greatly improve the heat recovery and utilization rate.

[0031] The collection assembly 8 includes a filter screen 801 and a collection box 802. The filter screen 801 is fixedly installed inside the box 7, and the collection box 802 is inserted into the box 7. The filter screen 801 can intercept impurities in the circulating gas and prevent impurities from entering the furnace 1 and affecting the firing quality of the insulators. The collection box 802 is used to collect the impurities intercepted by the filter screen 801 for subsequent processing. By setting up the collection assembly 8 composed of the filter screen 801 and the collection box 802, the effect of filtering impurities in the circulating gas and keeping the furnace clean is achieved, thereby improving the firing quality of the insulators.

[0032] The filter plate 801 is set as a double-layer stainless steel filter. The double-layer stainless steel filter has high filtration accuracy and strength, which can effectively intercept impurities of different particle sizes. At the same time, it has good corrosion resistance and high temperature resistance, and can work stably for a long time in harsh firing environments.

[0033] A through groove 9 adapted to the collection box 802 is provided on one side wall of the box body 7. The collection box 802 is inserted into the inside of the box body 7 through the through groove 9. A push-pull handle 10 is fixedly connected to one side wall of the collection box 802. The design of the through groove 9 allows the collection box 802 to be easily inserted into and pulled out of the box body 7, which is convenient for cleaning the collected impurities. The push-pull handle 10 provides operational convenience, allowing the operator to easily move the collection box 802. By setting the through groove 9 and the push-pull handle 10, the effects of convenient installation and disassembly of the collection box 802 and convenient cleaning of impurities are achieved, thereby improving operational efficiency.

[0034] Positioning blocks 11 are fixedly connected to one side wall of the collection box 802 and the box body 7. Positioning pins 12 are inserted into the two sets of positioning blocks 11. The cooperation of positioning blocks 11 and positioning pins 12 can ensure that the collection box 802 remains stable after installation, preventing it from shaking or shifting during operation, which would affect the filtration effect and normal operation of the equipment.

[0035] The top of the furnace body 1 is open, and a cover plate 13 is hinged to the top of the furnace body 1. The opening design of the top of the furnace body 1 facilitates the installation and removal of the insulator. The cover plate 13 is hinged to the furnace body 1 through the hinge, which can be opened and closed flexibly. It plays a sealing role during the firing process to prevent heat loss and external impurities from entering the furnace body 1.

[0036] Working principle: The insulator to be fired is placed into the furnace body 1, and the cover plate 13 is closed. The temperature control module 3 controls the heating wire 2 to heat up according to the preset temperature curve, thus firing the insulator in the furnace body 1. The hot air at the top of the furnace body 1 enters the first connecting pipe 601 through the air outlet pipe 4. Since the outer wall of the first connecting pipe 601 is covered with heat insulation material, heat loss is reduced. After the hot air enters the box body 7, it is filtered by the filter screen plate 801. Impurities are intercepted and fall into the collection box 802. The pump body 602 pumps the filtered gas through... The second connecting pipe 603 delivers heat to the inlet pipe 5 and then into the bottom of the furnace body 1, realizing the recycling of heat. When it is necessary to clean the impurities in the collection box 802, the positioning pin 12 is pulled out, and the collection box 802 is pulled out from the through groove 9 by pushing and pulling the handle 10. After cleaning, it is reinserted and the positioning pin 12 is inserted to fix it. Through the above working principle, the boiler realizes the precise firing of insulators, the recovery and utilization of heat, and the filtration and collection of impurities, which effectively improves the firing quality of insulators and reduces energy consumption and production costs.
