Description

Technical Field

[0001] This utility model relates to the field of heating furnace technology, specifically a heating furnace device with a heat treatment atmosphere control structure. Background Technology

[0002] A heating furnace is an industrial thermal equipment that heats materials or workpieces by burning fuel or converting electrical energy into heat. Heating furnaces are divided into vertical and horizontal types. In the chemical industry, heating furnaces are mainly used for heating liquid or gaseous raw materials. During operation, a heat source is placed at the bottom of the furnace, raising the temperature of the air inside. Heat-conducting pipes inside the furnace allow the liquid or gas to be heated to flow through them at a certain velocity. The heated air rises, further heating the heat-conducting pipes, ensuring the raw materials are fully utilized and achieving the desired heating effect. Upon investigation, a utility model patent (publication number: CN221685157U) discloses a vertical reaction furnace, which is roughly described as follows: The vertical reaction furnace includes a first heating chamber at the top and a second heating chamber at the bottom. The first heating chamber is equipped with a negative pressure dust suction pipe, an output port, a reaction medium gas pipe, and a catalyst inlet. An output pipe is fitted at the output port. A filter ring and a filter element assembly are installed inside the first heating chamber. Several filter pipes are installed on the bottom side of the filter ring. The filter element assembly includes multiple filter elements that cooperate with the filter pipes. The outer end of the negative pressure dust suction pipe is connected to a vacuum pump. The furnace designed in this utility model is vertical in shape. The reactants entering the furnace fall freely under the action of gravity, which increases the contact area and improves the reaction efficiency of the synthesis reaction, thus solving the problem of low reaction efficiency in existing furnaces.

[0003] In the above technical solution, the reactants are added from the top and fall freely under their own gravity, which increases the contact area and contact time between the reactants and the heat source and catalyst, thereby improving the reaction efficiency and uniformity. However, the atmosphere is prone to uneven distribution during the use of the heating furnace, which affects the heating effect. It is not easy to control the gas temperature if it is too high or too low. Insufficient gas affects the heating effect, and excessive reaction gas can easily lead to gas waste and increase production costs.

[0004] Therefore, this utility model provides a heating furnace device with a heat treatment atmosphere control structure to solve the above problems. Utility Model Content

[0017] 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.

[0018] This utility model provides a heating furnace device with a heat treatment atmosphere control structure, such as... Figure 1 and Figure 4 As shown, the furnace includes a combustion structure 1, which includes a fuel tank 101 and a burner 102. A furnace body structure 2 is installed on the top of the fuel tank 101. The furnace body structure 2 includes a furnace wall 201 and a cover plate 202. An atmosphere control and air intake structure 3 is connected to the outer wall of the fuel tank 101. The atmosphere control and air intake structure 3 includes an air intake pipe 302 and a conversion box 301. One end of the air intake pipe 302 is connected to a diffusion structure. A heating structure 4 is installed inside the fuel tank 101. The heating structure 4 includes an airflow equalization plate 401, a heater 402, and a vortex guide rib 404. A detection component 5 is installed on one side of the outer side of the furnace wall 201. The detection component 5 includes a slide rail 501, a slider 502, and a gas concentration detector 505.

[0019] A burner 102 is fixedly installed inside the fuel tank 101. The burner 102 has multiple sets of nozzles on its top and a control interface is installed at the bottom of the nozzles. A furnace wall 201 is fixedly installed on the top of the fuel tank 101. The furnace wall 201 has multiple sets of nozzles arranged vertically. A cover plate 202 is installed on the top of the furnace wall 201. A through hole is opened in the center of the outer wall of the cover plate 202.

[0020] The air inlet pipe 302 in the atmosphere control air inlet structure 3 is located on both sides of the outside of the furnace wall 201. One end of the air inlet pipe 302 is fixedly installed with a fixing plate, and the other end of the air inlet pipe 302 passes through the inside of the conversion box 301 and extends out of the outer wall.

[0021] The diffusion structure includes a gas box 303 and a diffusion pipe 304. The diffusion pipes 304 are arranged in a ring shape and are connected to each other through the gas box 303 to allow internal airflow. A diffuser extends from inside the gas box 303 and is connected to the inside of the furnace wall 201.

[0022] In operation, fuel is placed inside heater 402, and burner 102 ignites to generate high-temperature flame and flue gas, providing a heat source for the entire system. Multiple nozzles in burner 102 ensure that the fuel is fully atomized and mixed with air. A control interface receives control signals and adjusts the burner 102's flame intensity. Vertically distributed multiple furnace walls 201 effectively insulate against internal high temperatures, reducing heat loss and maintaining furnace thermal stability. A top cover 202 seals the furnace, and its central through-hole provides a passage for exhaust pipe 405 in heating structure 4, allowing combustion exhaust gas to escape to maintain stable furnace pressure and atmosphere renewal. Working gas is supplied from a gas source. The gas is fed into the furnace through the inlet pipe 302. The layout on both sides of the furnace wall 201 facilitates symmetrical gas intake. The fixed plate is used to firmly connect the inlet pipe 302 to the conversion box 301. The gas first enters the gas box 303, which acts as a pressure stabilizing chamber to stabilize the gas pressure and flow rate. Subsequently, the gas is distributed into the annularly distributed diffuser pipe 304. The annular distribution ensures that the gas can be released from the furnace interior in a laminar diffusion manner. The gas enters the interior of the furnace wall 201 at a lower speed and in a dispersed state through the diffuser pipe, avoiding uneven temperature of high-speed airflow. This achieves rapid and uniform diffusion and distribution of the atmosphere in the furnace, improving the uniformity and effect of heating.

[0023] Furthermore, in order to improve the effectiveness of the device, such as Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the airflow equalization plate 401 in the heating structure 4 is installed at the bottom of the burner 102. The outer surface of the airflow equalization plate 401 is uniformly provided with round holes. A heater 402 is vertically installed on the top of the airflow equalization plate 401. A heat-conducting pipe is fixedly installed inside the heater 402. A heat insulation cover 403 is movably sleeved on the outside of the heater 402. An exhaust pipe 405 is installed in the center inside the heater 402. The exhaust pipe 405 extends to the inner wall of the through hole for fitting.

[0024] The heating structure 4 also includes vortex guide ribs 404, which are inclined blades fixedly installed around the outer surface of the heat insulation cover 403.

[0025] In the detection assembly 5, the slide rail 501 is fixedly connected to the outer wall of the furnace wall 201. A slider 502 is slidably connected to the outer wall of the slide rail 501. A connecting plate is fixedly installed on the outer wall of the slider 502. The bottom of the connecting plate is fixedly connected to one end of the lead screw 504. The bottom end of the lead screw 504 is connected to the output shaft of the motor 503. A gas concentration detector 505 is fixedly installed on the top of the connecting plate.

[0026] When in use, the airflow equalization plate 401 is located above the burner 102. The blade angle of the vortex guide fin 404 rotates according to the surrounding rising hot airflow and intake airflow, enhancing the convective heat transfer efficiency between the airflow and the heat source, promoting the uniform distribution of the atmosphere inside the furnace, and ensuring the stability of heating. The exhaust pipe 405 passes through the center of the heater 402, and its upper end extends out of the furnace through the through hole of the cover plate 202, continuously discharging exhaust gas, maintaining the furnace environment, and preventing air from being drawn back into the furnace and disrupting the atmosphere. The motor 503 provides power to drive the lead screw 504 to rotate, converting the rotational motion of the lead screw 504 into linear up-and-down motion. The slider 502 slides along the fixed slide rail 501, ensuring the smoothness of the movement process, so that the gas concentration detector 505 fixed on the top of the connecting plate moves accordingly to perform detection work, measuring the atmosphere concentration at different height levels inside the furnace in real time, and ensuring the overall effectiveness of the heating furnace operation.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
