Abstract
Description
Technical Field
[0001] This utility model relates to the field of air supply technology for oxidation furnaces, and specifically to an air supply device for oxidation furnaces. Background Technology
[0002] An oxidizing furnace is a piece of equipment used in industrial production to achieve oxidation reactions of materials. It heats materials to induce chemical reactions in an oxygen-rich environment and is widely used in metal surface treatment, chemical synthesis, and other fields. Its core function is to maintain specific reaction conditions, such as temperature and pressure, to ensure the oxidation process proceeds efficiently. The air supply system is an important auxiliary system of the oxidizing furnace. Its main function is to supply air or specific gases into the furnace to provide the necessary oxygen for the oxidation reaction. It works in conjunction with the reaction requirements inside the furnace to help maintain a stable reaction environment and is a key component in ensuring the continuous and controllable progress of the oxidation reaction.
[0003] Current air supply devices have several drawbacks: air supply is prone to concentration, leading to uneven reactions inside the furnace; poor sealing performance often results in air leakage and unstable air volume; insufficient filtration levels allow impurities to enter and affect the reaction; and low air volume adjustment precision makes it difficult to adapt to different working conditions. Utility Model Content
[0004] The purpose of this invention is to provide an air supply device for an oxidation furnace to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an air supply device for an oxidation furnace, comprising an air outlet pipe, the bottom end of which vertically penetrates the middle of the top of the oxidation furnace, an air outlet is provided on one side of the outer wall of the bottom of the oxidation furnace, an air supply nozzle is transversely penetrating the interior of the air outlet, an air supply pipe is connected to the other end flange of the air supply nozzle, a fan is connected to the other end flange of the air supply pipe, a filter box is connected to the air inlet flange of the fan, and a filter mechanism is slidably connected to the inner walls of the left and right sides of the filter box;
[0006] The top center of the filter box extends vertically through the air hood;
[0007] The inner wall of the air outlet is fitted with a sealing mechanism.
[0008] The beneficial effects of this utility model are as follows: the connecting pipe of the air nozzle is connected to the flange of the air supply pipe, which facilitates disassembly and maintenance; the horn tube can increase the air diffusion area, making the air distribution more uniform and improving the fullness of the oxidation reaction; the sealing mechanism is convenient to disassemble and inspect through the screw-connected upper and lower fixing plates; its sealing half ring and sealing silicone layer can enhance the sealing of the air outlet, ensure stable air volume, and reduce losses; the air valve of the air supply pipe can adjust the flow rate to adapt to different reaction requirements, stabilize the furnace environment, and improve efficiency and quality controllability; the double-layer filter plate of the filtration mechanism improves the air purification effect, avoids impurities from affecting the reaction, and the sliding connection facilitates maintenance and ensures stable filtration effect.
[0009] To facilitate quick installation and disassembly, the bell-shaped structure of the bell-shaped tube allows for more even air distribution within the furnace, enabling connection between the air nozzle and the air supply pipe flange.
[0010] The air nozzle is further configured as follows: it is divided into a connecting pipe and a horn pipe, one end of the connecting pipe is flanged and connected to the air supply pipe, and the port of the horn pipe extends laterally through the interior of the air outlet.
[0011] By adopting the above technical solution, the connecting pipe in the air nozzle is connected to the flange of the air supply pipe, which facilitates the quick installation and disassembly of both, and makes it convenient for later maintenance or replacement of parts. The port of its horn tube runs through the air outlet, and its horn-shaped structure can increase the diffusion area when air enters the oxidation furnace, so that the air is more evenly distributed in the furnace, which helps to improve the fullness of the oxidation reaction.
[0012] To facilitate the inspection or replacement of the sealing components, the upper and lower fixed plates in the sealing mechanism are screwed together. The sealing half-ring, in conjunction with the sealing silicone layer on the outer wall, effectively fills the gap between the air outlet and the air nozzle, enhancing the sealing performance.
[0013] The sealing mechanism is further configured such that: the sealing mechanism includes an upper fixing plate, a lower fixing plate is screwed to the bottom end of the upper fixing plate, and a sealing half-ring is provided on the side of the upper fixing plate and the lower fixing plate near the air outlet. The outer wall of the upper and lower sealing half-rings is provided with a sealing silicone layer, and the upper and lower sealing half-rings are laterally engaged with the inner wall of the air outlet.
[0014] By adopting the above technical solution, in the sealing mechanism, the upper fixed plate and the lower fixed plate are screwed together, which is convenient for disassembly and assembly according to actual needs, and facilitates the inspection or replacement of sealing components. The sealing half ring is engaged with the inner wall of the air outlet, and together with the sealing silicone layer on the outer wall, it can effectively fill the gap between the air outlet and the air nozzle, enhance the sealing performance, and at the same time ensure the stability of the air volume entering the oxidation furnace and reduce energy loss.
[0015] To achieve precise control of airflow in the air supply duct by adjusting the opening and closing of the air valve, flexibly adjust the air supply volume, ensure a stable reaction environment inside the furnace, and improve the controllability of reaction efficiency and product quality:
[0016] A further feature is provided: an air valve is provided on the outer wall of the air supply pipe.
[0017] By adopting the above technical solution, an air valve is installed on the outer wall of the air supply duct. The air flow rate in the air supply duct can be precisely controlled by adjusting the opening and closing degree of the air valve. The air supply volume can be flexibly adjusted according to different reaction stages or reaction requirements in the oxidation furnace, ensuring a stable reaction environment in the furnace and improving the controllability of reaction efficiency and product quality.
[0018] To achieve a dual-layer filtration structure consisting of a filter screen and a fine filter plate, the filtration mechanism significantly improves air purification efficiency and prevents impurities from entering the oxidation furnace and affecting the reaction or contaminating the product. The sliding connection allows for quick and easy removal or installation of the filter plates, facilitating regular cleaning and replacement of the filter media.
[0019] The filter mechanism is further configured such that: the filter screen plate is slidably connected to the inner walls of the left and right sides of the filter box, and fine filter plates are slidably connected to the inner walls of the left and right sides of the filter box located directly below the filter screen plate.
[0020] By adopting the above technical solution, the filtration mechanism includes a filter screen and a fine filter plate, both of which are slidably connected inside the filter box. The dual-layer filtration structure can first filter larger impurities in the air through the filter screen, and then filter fine particles through the fine filter plate, which significantly improves the air purification effect and prevents impurities from entering the oxidation furnace and affecting the reaction or contaminating the product. The sliding connection method makes it easy to quickly pull out or install the filter plate, facilitates regular cleaning and replacement of the filter material, reduces maintenance difficulty, and ensures long-term stable filtration effect.

The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.
[0029] Please see Figures 1 to 5 An air supply device for an oxidation furnace includes an air outlet pipe 1, the bottom end of which is vertically inserted through the middle of the top of the oxidation furnace 2. An air outlet 3 is provided on one side of the bottom outer wall of the oxidation furnace 2. An air supply nozzle 4 is horizontally inserted through the air outlet 3. An air supply pipe 5 is connected to the flange at the other end of the air supply nozzle 4. A fan 6 is connected to the flange at the other end of the air supply pipe 5. A filter box 7 is connected to the flange at the air inlet end of the fan 6. Filtering mechanisms 8 are slidably connected to the inner walls on the left and right sides of the filter box 7.
[0030] The top center of the filter box 7 extends vertically through the air shroud 9;
[0031] The inner wall of the air outlet 3 is fitted with a sealing mechanism 10.
[0032] In this embodiment, as Figure 1 and Figure 3 and Figure 5 As shown, the air nozzle 4 is divided into a connecting pipe 401 and a horn pipe 402. One end of the connecting pipe 401 is connected to the air supply pipe 5 by a flange, and the port of the horn pipe 402 extends horizontally through the interior of the air outlet 3.
[0033] In this embodiment, as Figure 1 and Figure 4 As shown, the sealing mechanism 10 includes an upper fixing plate 1001, and a lower fixing plate 1002 is screwed to the bottom end of the upper fixing plate 1001. Both the upper fixing plate 1001 and the lower fixing plate 1002 are provided with sealing half rings 1003 on the side near the air outlet 3. The outer walls of the upper and lower sealing half rings 1003 are provided with a sealing silicone layer 1004, and the upper and lower sealing half rings 1003 are laterally engaged with the inner wall of the air outlet 3.
[0034] In this embodiment, as Figure 1 and Figure 3 As shown, the outer wall of the air supply duct 5 is equipped with an air valve 501.
[0035] In this embodiment, as Figure 1 and Figure 2 As shown, the filtration mechanism 8 includes a filter screen plate 801, which is slidably connected to the inner walls of the left and right sides of the filter box 7. Fine filter plates 802 are slidably connected to the inner walls of the left and right sides of the filter box 7 located directly below the filter screen plate 801.
[0036] The computer software involved in the hardware carriers such as wind turbines in the technical solution is software technology known to those skilled in the art. It is merely applied to the aforementioned hardware carriers. In other words, the computer software portion of the technical solution is an essential technical feature for solving the aforementioned technical problem, constituting a necessary technical feature for the technical problem solved by this application, but it is not a differentiating technical feature or a point of technical improvement. The applicant has not made any technical improvements to the computer software portion involved in the aforementioned related hardware carriers, nor is it a key technical point of the invention.
[0037] Therefore, the "fan" and other components involved in this application are physical functional modules that combine existing computer software programs or protocols with the hardware carrier of this application. The computer software programs involved in these physical functional modules are technologies known to those skilled in the art and are not improvements of this application. The improvement of this application should be the interaction between the various physical functional modules, that is, the improvement of the overall structure of the air supply device of this application, in order to solve the corresponding technical problems to be solved by this application.
[0038] The working process of the air supply device for the oxidation furnace is as follows:
[0039] First, the operator needs to pass the horn tube 402 of the air nozzle 4 horizontally through the air outlet 3 on the outer wall of the bottom of the oxidation furnace 2. Then, the sealing half ring 1003 of the upper fixing plate 1001 and the lower fixing plate 1002 near the air outlet 3 is tightly locked into the inner wall of the air outlet 3. The sealing silicone layer 1004 on the outer wall of the sealing half ring 1003 further enhances the sealing performance to prevent air from leaking from the gap between the air outlet 3 and the air nozzle 4. Then, the upper fixing plate 1001 and the lower fixing plate 1002 are screwed together and fixed.
[0040] Then, the operator can start the fan 6 (model: DJ-SSCF) through the external controller (model: S7-1200) to make it run and generate power, and draw outside air into the filter box 7 through the fan hood 9. In the filter box 7, the air first flows through the filter screen plate 801 of the filter mechanism 8 for preliminary filtration to remove larger impurities in the air. Then, the air that has passed through the preliminary filtration continues to flow downward and passes through the fine filter plate 802 of the filter mechanism 8 for finer filtration to further purify the air.
[0041] After filtration, the clean air will continue to be driven by the fan 6, so that the air is delivered to the air supply pipe 5. At this time, the air flow rate in the air supply pipe 5 can be controlled by manually adjusting the air valve 501 on the air supply pipe 5 to meet the air supply requirements of the oxidizer 2. When the air flows to the end in the air supply pipe 5, it will enter the connecting pipe 401 of the air supply nozzle 4, and then pass through the horn tube 402 of the air supply nozzle 4 horizontally through the air outlet 3 on the bottom outer wall of the oxidizer 2, and finally enter the interior of the oxidizer 2. During the process of the air passing through the air outlet 3, the sealing mechanism 10 that engages on the inner wall of the air outlet 3 will play a sealing role.
[0042] After the air enters the oxidation furnace 2 and participates in the reaction, the gas formed will eventually be discharged from the middle of the top of the oxidation furnace 2 through the air outlet pipe 1.
