Description

Technical Field

[0001] This utility model relates to the field of industrial equipment protection technology, and in particular to a protective component for a heating furnace control box. Background Technology

[0002] The heating furnace control box is the core equipment used to regulate the operation of the heating furnace. It integrates temperature, pressure and other control modules and electrical components to realize the setting of heating parameters, monitoring of operating status and safety protection, and ensure the stable operation of the heating furnace.

[0003] In complex industrial environments such as high temperature, dust, and flammable and explosive environments, protective components for heating furnace control boxes are required to isolate hazardous environments and ensure the stable operation of electronic components inside the control box. Heating furnace control box protective components typically use explosion-proof enclosures to resist explosive impacts, combined with highly efficient heat insulation, dustproof, and moisture-proof materials, thereby effectively preventing high temperature and dust intrusion, avoiding short circuits and component damage, and improving the safety and service life of the control box.

[0004] However, the existing protective components for heating furnace control boxes have the following shortcomings:

[0005] In the prior art, the protective components of the heating furnace control box require a fan to circulate air in the space to dissipate heat and cool down the electrical components. Therefore, a filter component is required to intercept dust. However, in complex industrial environments, the filter component is often blocked by the accumulation of impurities such as metal shavings and high-temperature dust, which greatly reduces the ventilation efficiency, causing the heat inside the box to be unable to be discharged in time. The electrical components age faster due to overheating, and may even cause equipment failure.

[0006] Therefore, we propose a protective component for the heating furnace control box to address the problems mentioned above. Utility Model Content

[0007] The purpose of this invention is to provide a protective component for a heating furnace control box. It utilizes a motor-driven high-speed rotating brush roller to sweep and clean clogged filters, quickly removing surface impurities. Driven by an electric push rod and guided by a sliding component, the cleaning component performs comprehensive reciprocating cleaning along the filter surface. Simultaneously, the electric push rod's drive causes the scraping component to move synchronously, performing deep scraping of the filter and effectively removing stubborn deposits, thus solving the problems mentioned in the background art.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a protective assembly for a heating furnace control box, comprising an explosion-proof box, two exhaust fans fixedly installed on the top of the explosion-proof box, two dust covers fixedly connected to the top of the explosion-proof box, two intake fans fixedly installed on one side of the outer wall of the explosion-proof box, a filter box fixedly connected to one side of the outer wall of the explosion-proof box, a filter screen fixedly connected to the inner surface of the filter box, two sliding grooves formed on the inner surface of the filter box, a sliding frame slidably embedded between the inner surfaces of the two sliding grooves, two bearings fixedly inserted into the inner surface of the sliding frame, a brush roller fixedly inserted between the interiors of the two bearings, a drive motor fixedly connected to one side of the outer wall of the brush roller, two guide rods fixedly connected to the inner surface of the filter box, a movable plate movably sleeved between the outer surfaces of the two guide rods, a set of buffer springs fixedly connected to the inner surface of the movable plate, a scraper fixedly connected between the outer surfaces of the set of buffer springs, and the outer surface of the scraper movably inserted inside the movable plate.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0025] Example 1, as shown in the attached document Figure 1 -Appendix Figure 4 As shown, this utility model provides a technical solution: a protective assembly for a heating furnace control box, including an explosion-proof box 1. Two exhaust fans 2 are fixedly installed on the top of the explosion-proof box 1, and two dust covers 3 are fixedly connected to the top of the explosion-proof box 1. Two intake fans 4 are fixedly installed on one side of the outer wall of the explosion-proof box 1. A filter box 5 is fixedly connected to one side of the outer wall of the explosion-proof box 1. A filter screen 6 is fixedly connected to the inner surface of the filter box 5. Two sliding grooves 7 are formed on the inner surface of the filter box 5. A sliding frame 8 is slidably embedded between the inner surfaces of the two sliding grooves 7. Two bearings 9 are fixedly inserted into the inner surface of the sliding frame 8. A brush roller 10 is fixedly inserted between the interiors of the two bearings 9. The outer surface of the brush roller 10 is... A drive motor 11 is fixedly connected to one side of the filter box 5. Two guide rods 12 are fixedly connected to the inner surface of the filter box 5. A movable plate 13 is movably sleeved between the outer surfaces of the two guide rods 12. A set of buffer springs 14 is fixedly connected to the inner surface of the movable plate 13. A scraper 15 is fixedly connected between the outer surfaces of the set of buffer springs 14. The outer surface of the scraper 15 is movably inserted into the interior of the movable plate 13. An electric push rod 16 is fixedly connected to the top of the filter box 5. The top of the sliding frame 8 is fixedly connected to the top of the electric push rod 16. A linkage frame 17 is fixedly connected between the sliding frame 8 and the top of the movable plate 13. The outer surface of the linkage frame 17 is movably inserted into the interior of the filter box 5.

[0026] The overall effect of Embodiment 1 is as follows: When the filter screen 6 is clogged due to the accumulation of impurities such as high-temperature dust, the drive motor 11 is first started, and its output end drives the brush roller 10 to rotate at high speed. The brush roller 10 cleans the filter screen 6 by high-speed rotation to remove most of the dust attached to the surface. Then, the electric push rod 16 is started, and its telescopic end drives the sliding frame 8 to rise and fall in the vertical direction. The sliding frame 8 drives the cleaning component to move synchronously, realizing a comprehensive sweeping of the filter screen 6. The movement of the sliding frame 8 is transmitted through the linkage frame 17. Under the guidance and support of the two guide rods 12, the linkage frame 17 drives the moving plate 13 to move down smoothly. The moving plate 13 then drives the scraper 15 to fall synchronously. The scraper 15 performs deep scraping and cleaning of the filter screen 6. Working in conjunction with the cleaning component, it scrapes away stubborn clumps of impurities that are difficult for the brush roller 10 to remove. Through the dual cleaning mechanism, the permeability of the filter screen 6 is ensured, and the smooth airflow is maintained, thereby ensuring efficient heat dissipation of the electrical components inside the explosion-proof box 1.

[0027] Example 2, as Figure 2-4As shown, four first rubber pads 18 are fixedly connected to the bottom of the explosion-proof box 1. Each of the four first rubber pads 18 is fixedly connected to the bottom of an upper protective sleeve 19. Each of the four upper protective sleeves 19 is fixedly connected to the top of its interior. Each of the four dampers 20 has a shock-absorbing spring 21 movably fitted on its outer wall. Each of the four dampers 20 has a lower protective sleeve 22 fixedly connected to its bottom. The outer walls of the four upper protective sleeves 19 are movably inserted into the interior of the four lower protective sleeves 22. Each of the four lower protective sleeves 22 has a second rubber pad 23 fixedly connected to its bottom. Each of the four second rubber pads 23 has a base plate 24 fixedly connected to its bottom.

[0028] The overall effect of Embodiment 2 is as follows: During use, when the heating furnace or other external equipment vibrates, the four dampers 20 first play an energy dissipation role, rapidly absorbing vibration energy through the damping effect of the internal fluid and slowing down vibration transmission; then the four shock-absorbing springs 21 further buffer and dampen the vibration, using elastic deformation to disperse the residual vibration impact force; the four first rubber pads 18 and the four second rubber pads 23, with their good elasticity and flexibility, isolate vibration transmission and effectively prevent vibration from directly acting on the explosion-proof box 1. The multiple shock-absorbing structures work together to ensure that the electrical components inside the explosion-proof box 1 maintain a stable operating state, avoiding problems such as loose connections and component damage caused by vibration, thus significantly improving the reliability of the heating furnace control box, thereby extending the service life of the equipment and reducing the maintenance cost of failures caused by vibration.

[0029] The working principle of the entire equipment is as follows: During use, firstly, the two exhaust fans 2 and two intake fans 4 are started. The exhaust fans 2 generate suction, creating negative pressure inside the explosion-proof box 1. Meanwhile, the intake fans 4 generate a strong airflow, rapidly drawing in cold outside air and creating a circulating convection within the box, thus efficiently cooling the internal electrical components. Simultaneously, the dust cover 3 effectively intercepts external dust and debris, preventing them from falling into the explosion-proof box 1 and the two exhaust fans 2. When the filter screen 6 becomes clogged with dust and impurities, firstly, the drive motor 11 is started, its output driving the brush roller 10 to rotate at high speed. The brush roller 10 cleans the filter screen 6 through high-frequency rotation, initially removing surface impurities. Then, the electric push rod 16 is started, its extension and retraction ends driving the sliding... The vertical lifting of the frame 8 drives the cleaning components to move synchronously, achieving full-area cleaning of the filter screen 6. The displacement of the sliding frame 8 is transmitted through the linkage frame 17, causing the moving plate 13 to move smoothly downward. The moving plate 13 drives the scraper 15 to deeply scrape the filter screen 6, working in conjunction with the cleaning components to scrape away stubborn clumps of impurities that are difficult to remove with a brush, ensuring the permeability of the filter screen 6 and maintaining smooth airflow. In addition, when the heating furnace or external equipment vibrates, the four dampers 20 first absorb the impact energy and slow down the transmission of vibration; the four shock-absorbing springs 21 further buffer the deformation and disperse the residual vibration force; the four first rubber pads 18 and the second rubber pads 23 isolate the transmission of vibration due to their elastic buffering characteristics. The multiple shock-absorbing structures work together to ensure the stable operation of the electrical components inside the explosion-proof box 1.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
