Embodiment

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to the attached Figures 1-10, an embodiment provided by the present invention: an electric and gas dual-purpose multi-rod heating furnace, including a material rack assembly 1, a furnace body 2, and a combustion chamber 3. The material rack assembly 1 is arranged on one side of the furnace body 2, the combustion chamber 3 is arranged on the top of the furnace body 2, a vibration rod mechanism 4 is arranged inside the furnace body 2, waste heat recovery assemblies 5 are arranged on both sides of the combustion chamber 3, the combustion chamber 3 is connected with a combustion gun 302, and the combustion chamber 3 includes a combustion rack 301, a combustion gun 302, and a heating box 304. The heating box 304 is nested inside the combustion rack 301, and the combustion gun 302 is located on one side of the combustion rack 301. The waste heat recovery assembly 5 is communicated with the combustion chamber 3 inside the furnace body 2. A ladder 6 is also arranged around the furnace body 2 to facilitate climbing onto the furnace body 2 for overhauling the combustion chamber 3, and the fence 7 strengthens the safety of working at heights. The material rack assembly 1 can accommodate and support about multiple aluminum rods 8 at one time for heating, and the material rack assembly 1 is made of high-temperature resistant metal materials. The furnace body 2 is the main component of the heating furnace. The furnace body 2 is a closed space to ensure the heating effect and temperature control, while improving the processing efficiency while saving energy. The combustion chamber 3 is the key heat supply component of the heating furnace, responsible for providing high-efficiency heat energy. It provides two forms of heating effects through the heating box 304 and the combustion gun 302 inside the combustion rack 301. When using natural gas to heat the aluminum rods 8, the combustion gun 302 is responsible for heat supply. When using electricity to heat the aluminum rods 8, the heating box 304 is responsible for heat supply. Through the two heat supply methods, the heating furnace can use electricity as energy to heat during the low electricity consumption period of the peak-valley electricity, and can choose to use natural gas to heat during the peak electricity consumption period, effectively reducing the operation cost of the enterprise and improving the efficiency. The vibration rod mechanism 4 keeps the aluminum rods 8 in a separated state during the heating process through vibration, preventing them from sticking together at high temperatures. The waste heat recovery assembly 5 effectively recovers the waste heat generated during the combustion process and transfers it back into the furnace body 2 for reuse, improving the energy utilization efficiency.

[0019] The material rack assembly 1 includes a storage rack 101, a low-position automatic rod-loading and feeding rack 102, and a discharging rack 103. The low-position automatic rod-loading and feeding rack 102 faces the feeding window 206 of the furnace body 2. The storage rack 101 and the low-position automatic rod-loading and feeding rack 102 are placed at a right angle on one side of it. The number of storage racks 101 is two, one is close to the furnace body 2, and the other is far from the furnace body 2. A discharging rack 103 is arranged at one end of the storage rack 101 far from the low-position automatic rod-loading and feeding rack 102. The discharging rack 103 includes a bracket 10301 and a guiding rack 10302. The bracket 10301 is located between the storage rack 101 and the furnace body 2. The guiding rack 10302 is at a right angle to the storage rack 101 and is placed above the storage rack 101. The low-position automatic rod-loading and feeding rack 102 is provided with a lifting mechanism 10201. The lifting mechanism 10201 is provided with two synchronous rollers 1020102. The two synchronous rollers 1020102 are linked by a first chain 1020103. A number of hooks 1020101 are arranged on the first chain 1020103.

[0020] The rack assembly 1 is used to temporarily store the aluminum bars 8 to be processed, and feed the aluminum bars into the furnace body 2 or receive the processed aluminum bars 8 according to the process requirements. Generally, the aluminum bars are placed on the storage rack 101 by a forklift or a crane, and then the low-position automatic bar loading rack 102 conveys the aluminum bars 8 into the heating furnace. Compared with the traditional method of feeding the bars into the furnace by a forklift, it is relatively safer and more reliable. The low-position automatic bar loading rack 102 faces the feeding window 206 of the furnace body 2 and has an automatic bar loading function, which is specifically implemented by the lifting mechanism 10201. When the two synchronous rollers 1020102 of the lifting mechanism 10201 rotate, they drive the hooks 1020101 on the first chain 1020103. There are two lifting mechanisms 10201 in total on the low-position automatic bar loading rack 102, and the aluminum bars 8 can be evenly stressed and transferred from the storage rack 101 to the low-position automatic bar loading rack 102 under the lifting action of the two groups of hooks 1020101, and then the rollers of the low-position automatic bar loading rack 102 feed the aluminum bars 8 into the feeding window 206. The unloading rack 103 is used to receive the processed aluminum bars 8 at the unloading window 207, and is used to support and guide the movement of the aluminum bars 8 during the unloading process to ensure the smooth and safe unloading of the aluminum bars 8.

[0021] The furnace body 2 includes a frame 201, a material supporting frame 202, and a feeding roller assembly 203. A number of frame members 20201 are arranged inside the frame 201, and the frame members 20201 are arranged equidistantly and parallelly inside the frame 201. One end of the frame member 20201 is connected to the front turning oil cylinder 208, and the other end is connected to the rear turning oil cylinder 209. The feeding roller assembly 203 includes a number of rollers 20302, and the rollers 20302 penetrate the frame 201, and a bearing 20301 is provided at one end exposed outside the frame 201. A number of rollers 20302 are linked by a second chain 20303.

[0022] An unloading window 207 is provided on the frame 201. The unloading window 207 and the feeding window 206 are on the same side of the frame 201. The unloading window 207 faces the bracket 10301. Temperature measuring elements 205 and probe elements 204 are respectively provided on both sides of the frame 201. The middle part of the frame member 20201 is a cross bar 2020101, and the two sections of the cross bar 2020101 are respectively hinged with a first vertical bar 2020102 and a second vertical bar 2020103. The first vertical bar 2020102 is connected to the front turning oil cylinder 208, and the second vertical bar 2020103 is connected to the rear turning oil cylinder 209.

[0023] The equidistant parallel arrangement of the frame member 20201 provides uniform support points for the aluminum rod 8, increasing the overall stability of the heating furnace. The front tilting oil cylinder 208 and the rear tilting oil cylinder 209 are connected to both ends of the frame member and are used to control the front and rear tilting operations of the frame member 20201. The aluminum rod 8 enters the furnace body 2 through the feeding roller assembly 203 after passing through the feeding window 206. The front tilting oil cylinder 208 controls the frame member 20201 to transfer the aluminum rod 8 from the feeding roller assembly 203 to the material receiving rack 202. After the aluminum rod 8 is heated, the rear tilting oil cylinder 209 then transfers the aluminum rod 8 from the material receiving rack 202 to the feeding roller assembly at the discharging window 207, and sends it out of the furnace body 2 for recycling, completing the heating process.

[0024] The combustion chamber 3 includes a combustion rack 301, a combustion gun 302, and a heating box 304. A blower 303 is arranged at a position on one side of the combustion rack 301 facing the combustion gun 302. The blower 303 penetrates through the combustion rack 301, and the heating box 304 is located on both sides of the air outlet of the blower 303.

[0025] The heating box 304 is composed of a number of heating rods 30401, and the heating rods 30401 are detachably nested in the heating box 304.

[0026] The combustion chamber 3 is responsible for providing heat sources to heat the aluminum rod 8. Specifically, the combustion rack 301 uses two heat sources, namely the combustion gun 302 and the heating box 304. The combustion rack 301 is the main support structure of the combustion chamber 3. The combustion gun 302 uses natural gas as a raw material and is used to spray fuel and regulate the combustion process. By controlling the spraying and mixing of fuel, it ensures good fuel combustion effect in the combustion chamber 3. There are a number of detachable heating rods 30401 in the heating box 304. The heating box 304 generates heat using electricity, and the heating rods 30401 can be conveniently installed and replaced.

[0027] The blower 303 penetrates through the combustion rack 301 and is used to provide the oxygen and wind required for combustion. Whether the combustion gun 302 or the heating box 304 is selected to generate heat, the blower 303 can provide the required oxygen and wind to the corresponding components, improving the utilization efficiency of the blower 303.

[0028] The vibrating rod mechanism 4 includes a fixed bracket 401, a supporting rod 402, and a ejector rod 403. The vibrating rod mechanism 4 is arranged on one side of the material receiving rack 202. The fixed bracket 401 is connected to the furnace body 2, the supporting rod 402 is connected to the middle oil cylinder, and the ejector rod 403 is linked with the second vertical rod 2020103 through a transverse rotating shaft.

[0029] The vibrator mechanism 4 vibrates the aluminum rod 8, and vibrates once every time the rod is turned over, so that the adhesion of the aluminum rods 8 caused by high temperature is shaken off. The fixed bracket 401 provides a stable support point for the vibrator mechanism 4. The support rod 402 is connected to the middle oil cylinder and plays a role in bearing and transmitting force. The middle oil cylinder realizes the control and adjustment of the vibrator mechanism 4 by controlling the lifting movement of the support rod 402; the ejector rod 403 is linked with the second vertical rod 2020103 through a horizontal rotating shaft, so as to realize the synchronization of rod turning and vibration.

[0030] The waste heat recovery component 5 includes a base 501, a pipeline valve group 502, and a stainless steel small square pipe 504. The base 501 is fixedly connected to the frame 201. The stainless steel small square pipe 504 is located above the frame 201. The pipeline valve group 502 is located at the bottom of the base 501. The outside of the stainless steel small square pipe 504 is wrapped by an outer sealing plate 503. Air inlets 505 and air outlets 506 are arranged at the lower edges on both sides of the outer sealing plate 503.

[0031] The pipeline valve group 502 includes a cylinder 50201 and a valve flap 50202. The valve flap 50202 is matched with the air holes of the base 501, and the valve flap 50202 is connected to the cylinder 50201 through a reversing connecting rod.

[0032] Furthermore, the waste heat recovery component 5 is used to recover the waste heat generated by combustion and reuse it. The base 501 is fixedly connected to the frame 201, providing support and stability for the waste heat recovery component 5, ensuring the overall airtightness and avoiding heat loss. The pipeline valve group 502 is used to control whether the gas generated by combustion enters the stainless steel small square pipe 504 for waste heat recovery. The pipeline valve group 502 includes a cylinder 50201 and a valve flap 50202. The valve flap 50202 is matched with the air holes on the base. Through the connection of the cylinder 50201 and the reversing connecting rod, the control of the valve flap 50202 is realized, and then the on-off state of the smoke exhaust pipeline of the base 501 is controlled. The stainless steel small square pipe 504 absorbs the waste heat generated by combustion during the smoke exhaust process. The dense stainless steel small square pipes 504 can absorb a large amount of heat. When the fan 303 blows air, the heat of the stainless steel small square pipes 504 re-enters the furnace body 2 through the air inlets 505, supplementing the heat required during the heating process of the aluminum rod 8, achieving the purpose of improving energy efficiency and reducing fuel consumption. The outer sealing plate 503 wraps the outside of the stainless steel small square pipe 504, playing a role in protection and heat insulation.

[0033] The specific working mode of this heating furnace is as follows: The aluminum bars 8 are arranged on the storage rack 101, fed into the low-position automatic bar-feeding rack 102, and enter the furnace body 2 through the feeding window 206, and are heated through the combustion chamber 3. There are two heating methods in the combustion chamber 3. One is to burn natural gas in the combustion chamber 3 through the combustion gun 302, and the other is to make the heating box 304 generate heat through electricity. Enterprises can choose a suitable heating method according to the peak and valley time of electricity. After the aluminum bars 8 enter the furnace body 2, the bearing rack 202 transfers the aluminum bars 8 from the feeding roller assembly 203 to the rack member 20201 for formal heating. During the heating process, the bearing rack 202 and the bar-shaking mechanism 4 can realize the flipping and shaking of the aluminum bars 8 to avoid the aluminum bars 8 from sticking due to high temperature, which affects the appearance and performance of the aluminum bars 8. In addition, the combustion chamber 3 is provided with a waste heat recovery component 5, which can return the waste heat generated by the combustion chamber 3 to the furnace body 2 for reuse. After the heating is completed, the bearing rack 202 transfers the aluminum bars 8 to the feeding roller assembly 203 on one side of the discharging window 207 and sends them out of the furnace body 2, and they are recycled by the discharging rack 103 to complete the entire heating process.

[0034] Through the above work process, the heating furnace can realize the rapid heating and processing of aluminum bars, improve production efficiency and product quality, and is safe and reliable; at the same time, through waste heat recovery, it can maximize the use of energy and achieve the goal of energy conservation and environmental protection.
