Description

Technical Field

[0001] The utility model relates to the technical field of mechanical engineering equipment, in particular to a furnace cover opening structure. Background Art

[0002] The design of the furnace cover opening structure is crucial for improving the safety, convenience and efficiency of operation. Through a reasonable opening structure design, it can ensure that the furnace is safer, more efficient and easier to maintain during use, thereby enhancing the overall use experience and economic benefits.

[0003] Although the current technology has many advantages, its disadvantages are that due to the large size of some furnace covers, the area and volume of the furnace cover will correspondingly be larger, which leads to the furnace cover being too heavy. When directly driven by a motor to open the heavy furnace cover, the motor requires a greater torque force, resulting in accelerated wear of the motor and shortening its service life. At the same time, since the furnace cover needs to be opened frequently, the contact surface between the furnace cover and the furnace body often rubs, resulting in an increase in the gap between the furnace cover and the furnace body, leading to poor sealing of the furnace body. The poor sealing causes heat to escape from the furnace body gap, reducing the effective utilization of heat inside the furnace, lowering the thermal efficiency, and in order to maintain the required temperature, the furnace needs to consume more fuel or electricity, increasing the operating cost. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a furnace cover opening structure to solve the problems raised in the above background art.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a furnace cover opening structure, comprising: a fixed frame and a furnace body. A double-shaft motor is fixedly connected to the outer surface of the fixed frame. Two rotating shafts I are arranged on the output shaft of the double-shaft motor. Cam and support block I are fixedly installed on the outer surface of each of the two rotating shafts I. Fixed rods are fixedly connected to the inner surfaces of the two cams. Rotating long rods are fixedly connected to the outer surfaces of the two fixed rods. Rotating shafts II are fixedly installed on the inner surfaces of the two rotating long rods. Support block II is movably sleeved on the outer surfaces of the two rotating shafts II. Two rotating short rods are fixedly installed on the outer surfaces of each of the two rotating shafts II. The multiple rotating short rods are evenly divided into two groups. Rotating shafts III are movably embedded in the inner surfaces of the two groups of rotating short rods. Support block III is movably sleeved on the outer surfaces of the two rotating shafts III. A sealing cover is fixedly connected to the outer surfaces of the two support blocks III. A sealing mechanism is arranged on the outer surface of the sealing cover, reducing the direct load borne by the double-shaft motor and prolonging the service life of the double-shaft motor, and through the lever principle, a smaller power source is used to drive a heavier object.

[0006] As a preferred embodiment, the sealing mechanism includes an airbag. A fixing block is fixedly connected to the top of the airbag, and the fixing block is fixedly connected to the bottom of the sealing cover. A compressed air hose is fixedly connected to the outer surface of the airbag. A notch is formed on one side of the furnace body close to the airbag, which avoids the leakage of heat inside the furnace body, reduces the heat dissipation loss to a certain extent, and improves the energy utilization rate.

[0007] As a preferred embodiment, the furnace body is arranged on the outer surface of the fixing frame. Both of the first support block and the second support block are fixedly connected to the outer surface of the fixing frame. The sealing cover is movably embedded in the inner surface of the furnace body, and the second support block can support the second rotating shaft.

[0008] As a preferred embodiment, the airbag is movably embedded in the inner surface of the notch, and the compressed air hose is movably embedded in the inner surfaces of the sealing cover and the fixing block. The airbag is made of silica gel, which is not only heat-resistant, but also has good chemical resistance, ductility and wear resistance. Under the action of compressed air, the airbag can fill the notch to avoid the leakage of heat inside the furnace body.

[0009] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0010] 1. The present utility model utilizes the lever principle to disperse the driving force of the double-shaft motor to the rotating long rod, and then uses the second rotating shaft as the fulcrum to drive the rotating short rod to open the sealing cover plate, thereby reducing the direct load borne by the double-shaft motor, prolonging the service life of the double-shaft motor, and realizing the driving of a heavier object by a smaller power source through the lever principle, reducing the production cost to a certain extent.

[0011] 2. The airbag used in the present utility model is made of silica gel, which is not only heat-resistant, but also has good chemical resistance, ductility and wear resistance. The airbag expands through compressed air and fills the notch, avoiding the leakage of heat inside the furnace body, reducing the heat dissipation loss to a certain extent, improving the energy utilization rate, and reducing the production cost.

Detailed implementation manners

[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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the present invention provides a technical solution: a furnace cover opening structure, including: a fixed frame 1 and a furnace body 2. A biaxial motor 3 is fixedly connected to the outer surface of the fixed frame 1. There are two first rotating shafts 4 on the output shafts of the biaxial motor 3. Cam 6 and first supporting block 5 are fixedly installed on the outer surfaces of the two first rotating shafts 4. Fixed rods 7 are fixedly connected to the inner surfaces of the two cams 6. Rotating long rods 8 are fixedly connected to the outer surfaces of the two fixed rods 7. Second rotating shafts 9 are fixedly installed on the inner surfaces of the two rotating long rods 8. Second supporting blocks 10 are movably sleeved on the outer surfaces of the two second rotating shafts 9. Two rotating short rods 11 are fixedly installed on the outer surfaces of the two second rotating shafts 9. The multiple rotating short rods 11 are evenly divided into two groups. Third rotating shafts 12 are movably embedded in the inner surfaces of the two groups of rotating short rods 11. Third supporting blocks 13 are movably sleeved on the outer surfaces of the two third rotating shafts 12. A sealing cover 14 is fixedly connected to the outer surfaces of the two third supporting blocks 13. A sealing mechanism is arranged on the outer surface of the sealing cover 14, which reduces the direct load borne by the biaxial motor 3, prolongs the service life of the biaxial motor 3, and through the lever principle, realizes driving a heavier object with a smaller power source, and reduces the production cost to a certain extent.

[0019] As Figures 1-3 shown, the sealing mechanism includes an airbag 15. A fixed block 18 is fixedly connected to the top of the airbag 15. The fixed block 18 is fixedly connected to the bottom of the sealing cover 14. A compressed air hose 17 is fixedly connected to the outer surface of the airbag 15. A notch 16 is opened on one side of the furnace body 2 close to the airbag 15, which avoids the leakage of heat inside the furnace body 2, reduces the heat dissipation loss to a certain extent, improves the utilization rate of energy, and reduces the production cost.

[0020] As Figures 1-3As shown in the figure, the furnace body 2 is arranged on the outer surface of the fixing frame 1. Both the first support block 5 and the second support block 10 are fixedly connected to the outer surface of the fixing frame 1. The sealing cover 14 is movably embedded in the inner surface of the furnace body 2. The first support block 5 can support the first rotating shaft 4.

[0021] As Figures 1-3 shown in the figure, the airbag 15 is movably embedded in the inner surface of the notch 16. The compressed air hose 17 is movably embedded in the inner surfaces of the sealing cover 14 and the fixing block 18. The airbag 15 is made of silica gel. Silica gel is not only heat-resistant, but also has good chemical resistance, ductility and wear resistance. It can fill the notch 16 under the action of compressed air, avoid the leakage of heat inside the furnace body 2, and reduce the heat dissipation loss.

[0022] Working principle: This device is a furnace cover opening structure. When opening the furnace cover, start the double-shaft motor 3 on the fixing frame 1. The double-shaft motor 3 drives the first rotating shaft 4 to rotate through the output shaft. The first rotating shaft 4 drives the fixed rod 7 to rotate through the cam 6. The fixed rod 7 drives the second rotating shaft 9 to rotate through the rotating long rod 8. The second rotating shaft 9 drives the third rotating shaft 12 to make an arc rotation with the second rotating shaft 9 as the center. Then, the third rotating shaft 12 drives the sealing cover 14 to make an arc movement with the second rotating shaft 9 as the center through the third support block 13, and then the sealing cover 14 is opened. The second support block 10 can support the second rotating shaft 9, and the first support block 5 can support the first rotating shaft 4. Using the lever principle, connect the rotating short rod 11 with the relatively heavy sealing cover 14, and indirectly connect the rotating long rod 8 with the double-shaft motor 3, so that the double-shaft motor 3 does not need to generate a large torque force and load, and can also open the sealing cover 14, improving the service life of the double-shaft motor 3.

[0023] After closing the sealing cover 14, connect the compressed air hose 17 to the air source, so that compressed air enters the airbag 15 under the fixing block 18, causing the airbag 15 to expand and fill the notch 16 to achieve sealing.

[0024] The above is only a preferred embodiment of the present invention, and does not limit the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
