Description

Technical Field

[0001] This utility model relates to the field of electric furnace technology, specifically to an electric furnace structure. Background Technology

[0002] An electric furnace is a type of equipment that converts electrical energy into heat energy to achieve heating. It is widely used in various scenarios such as industrial smelting, household cooking, and laboratory heating. In the structure of an electric furnace, the dust hood is a collection device designed to collect pollutants such as smoke and dust generated during the heating process. It is usually installed on the top or side of the furnace body and is typically made of high-temperature resistant metal sheet. Its shape is adapted to the furnace opening, and the sealing structure reduces the leakage of pollutants. The dust hood is connected to the exhaust pipe and purification system. During operation, it uses the principle of negative pressure to suck in metal oxide dust, fuel combustion exhaust gas, etc. generated in the furnace, preventing pollutants from spreading into the working environment. This not only protects the health of operators but also reduces pollution to equipment and the surrounding environment. It is an important part of the environmental protection design of industrial electric furnaces.

[0003] A search revealed a Chinese patent (CN219223360U) disclosing a dust collector hood for a medium-frequency electric furnace. The hood includes a main body, a rotating cover, a left-end dust outlet, a connecting box, and an end connecting box. The connecting box is located at the rear end of the main body, with an end connecting box connected to its upper part. The rotating cover is located at the upper part of the main body, with a connecting block connected to its upper end. A sealing gasket is located on the inner side of the rotating cover. The main body has a left-end dust outlet and a right-end dust outlet at its upper part. A fixed connecting block is connected to the upper part of the connecting box. This invention allows the rotating cover to rotate on the upper part of the main body via the connecting block, facilitating maintenance of the main body. Bolt connections allow for the installation and fixing of the flue gas pipes to the upper parts of the left and right-end dust outlets, enabling the discharge of dust from inside the main body.

[0004] The aforementioned patent proposes to detachably connect the dust collector hood to the electric furnace body using bolts, aiming to facilitate disassembly and cleaning. However, in actual use, the dust collector hood of industrial electric furnaces is relatively large in size, designed to fit the furnace body and meet dust collection requirements. When cleaning or replacing the hood, tools must be used to remove the bolts, and each bolt must be unscrewed individually. This process is time-consuming and labor-intensive, and the limited operating space increases the difficulty of disassembly. Industrial production has high requirements for continuity, and this inefficient disassembly will prolong equipment downtime, affect production progress, and cause capacity loss. Therefore, we propose an electric furnace structure. Utility Model Content

[0005] The technical problem to be solved by this application is: how to quickly disassemble the dust collector hood and the electric furnace body. To address the aforementioned technical problems, this application provides an electric furnace structure, including an electric furnace and a furnace cover disposed on the upper side of the furnace. A mounting plate is disposed on one side of the furnace cover, and a dust hood body is disposed on one side of the mounting plate. Two locking mechanisms are disposed between the mounting plate and the dust hood body, and the two locking mechanisms are used to connect the mounting plate and the dust hood body. Each locking mechanism includes a fixing block, which is rotatably mounted on the mounting plate and is used to fix the dust hood body to the mounting plate.

[0006] In some embodiments, a movable block is provided at one end of the fixed block, the movable block is rotatably mounted on the mounting plate, and a connecting shaft is provided at the other end of the fixed block.

[0007] In some embodiments, a shaped groove is provided at one end of the connecting shaft away from the fixing block, the inner wall of the shaped groove is shaped like a cross, and the opening of the shaped groove is shaped like an arc.

[0008] In some embodiments, the dust hood body has a mounting hole on the side near the mounting plate at the position of two fixing blocks opposite each other. The fixing blocks extend through the mounting hole into the interior of the dust hood body. A mounting plate is provided inside the dust hood body at the position opposite to the fixing blocks. A mounting groove is provided on the side of the dust hood body away from the mounting hole. The mounting groove is opposite to the mounting hole.

[0009] In some embodiments, the locking mechanism further includes a drive mechanism mounted on the dust cover body, the drive mechanism being used to drive the fixed block to rotate.

[0010] In some embodiments, the driving mechanism includes a mounting block rotatably mounted inside the mounting plate.

[0017] The dust collector hood body 4 has mounting holes 41 and mounting grooves 43, which are positioned opposite each other. A mounting plate 42 is also provided inside the dust collector hood body 4. The mounting holes 41, mounting grooves 43, and mounting plate 42 are all used to install a locking mechanism 5. Installing the locking mechanism 5 allows for easier connection between the mounting plate 3 and the dust collector hood body 4. A mounting plate 3 is placed between the furnace cover 2 and the dust collector hood body 4. A movable block 51 is mounted on the mounting plate 3. A fixed block 52 is rotatably mounted on the mounting plate 3 via the movable block 51. The fixed block 52 can rotate around the movable block 51. The fixing block 52 can lock and unlock the dust collector hood body 4. The dust collector hood body 4 is equipped with a drive mechanism 54, which consists of a knob 541, a fixing plate 542, a mounting block 543, a connecting shaft 544, and a locking block 545. These components are connected to each other to form a whole, which is used to connect with the fixing block 52 and drive the fixing block 52 to rotate. This structure makes the disassembly and assembly of the dust collector hood body 4 simpler and faster, and facilitates the inspection, cleaning and replacement of the dust collector hood body 4, thereby improving work efficiency.

[0018] Example 2: Based on Example 1, such as Figure 5As shown, a movable block 51 is provided at one end of the fixed block 52, and the movable block 51 is rotatably mounted on the mounting plate 3. A connecting shaft 53 is provided at the other end of the fixed block 52. A special-shaped slot 531 is provided at the end of the connecting shaft 53 away from the fixed block 52. The inner wall of the special-shaped slot 531 is shaped like a cross, and the opening of the special-shaped slot 531 is rounded. The locking mechanism 5 also includes a drive mechanism 54 mounted on the dust cover body 4. The drive mechanism 54 is used to drive the fixed block 52 to rotate. The drive mechanism 54 includes a mounting block 543 rotatably mounted inside the mounting plate 42. A knob 541 is provided at one end of the mounting block 543. The knob 541 is placed inside the mounting groove 43. A fixed plate 542 is provided on one side of the knob 541. A connecting shaft 544 is provided at the other end of the mounting block 543. A locking block 545 is provided at the end of the connecting shaft 544 away from the mounting block 543. The outer wall of the locking block 545 is shaped like a cross, and the locking block 545 is engaged with the special-shaped slot 531.

[0019] A movable block 51 is installed on the mounting plate 3. A fixed block 52 is rotatably installed through the movable block 51. The fixed block 52 has a circular cross-section. A connecting shaft 53 is fixedly installed on one side of the circular cross-section of the fixed block 52. A special-shaped slot 531 is opened at the end of the connecting shaft 53. An mounting plate 42 is provided inside the dust hood body 4. The mounting block 543 is rotatably installed inside the mounting plate 42. That is, the mounting block 543 can rotate around its own axis inside the mounting plate 42. One side of the mounting block 543 is connected to the knob 541. The knob 541 is placed inside the mounting slot 43, and the outer surface of the knob 541 is flush with the outer wall of the dust hood body 4 and does not protrude from the outer wall of the dust hood body 4. A fixed plate 542 is provided at the end of the knob 541 located on the outer wall of the dust hood body 4. The fixed plate 542 can be used as the force point when the operator turns the knob 541, making it easy to apply force to turn the knob 541. The mounting block 543 is located inside the dust collector body 4, and one end is connected to the connecting shaft 544. The end of the connecting shaft 544 is provided with a locking block 545. The shape of the locking block 545 is completely consistent with the shape of the irregular slot 531, which can achieve precise locking fit. The outer extension of the entrance of the irregular slot 531 is set as a smooth arc. This arc design makes the locking block 545 enter the irregular slot 531 more smoothly and reduces jamming. When installing the dust hood body 4, the operator aligns the dust hood body 4 with the mounting plate 3, aligning the two fixing blocks 52 on the mounting plate 3 with the two mounting holes 41 on the dust hood body 4, and pushes the dust hood body 4 closer to the mounting plate 3, causing the connecting shaft 1 53 to gradually approach the connecting shaft 2 544 inside the dust hood body 4, until the locking block 545 is completely submerged in the irregular groove 531, completing the initial positioning and locking. Next, the operator uses the fixing plate 542 as a point of leverage and rotates the knob 541, turning it 90 degrees. During this process, the knob 541 drives the mounting block 543, the connecting shaft 2 544, and the locking block 545 to rotate synchronously. Because the locking block 545 is engaged with the irregular groove 531, the connecting shaft 1 53 and the fixing block 52 will also rotate synchronously with the locking block 545. After activation, the edge of its circular cross-section will tightly press the outer wall of the dust hood body 4 near the mounting plate 3 into the gap between the fixing block 52 and the mounting plate 3, thus firmly fixing the dust hood body 4 to the mounting plate 3. When it is necessary to disassemble the dust hood body 4, the operation steps are reversed from the installation: turn the knob 541 90 degrees in the opposite direction to release the fixing block 52 from pressing the outer wall of the dust hood body 4, and then pull the dust hood body 4 to release the locking block 545 from the irregular locking groove 531, so that the dust hood body 4 can be removed from the mounting plate 3. This structural design makes the disassembly and assembly of the dust hood body 4 without the need for additional tools, and can be completed by manually turning the knob 541. The operation is simpler and faster, and it is convenient to carry out maintenance, cleaning and replacement of the dust hood body 4, thereby effectively improving work efficiency.

[0020] Based on the above embodiments, the following is the complete working principle of the above embodiments: In use, first, the furnace cover 2 on the upper side of the electric furnace 1 is closed. At this time, the mounting plate 3 on one side of the furnace cover 2 provides a base for the installation of the dust hood body 4. When installing the dust hood body 4, the operator needs to align the dust hood body 4 with the mounting plate 3, so that the two fixing blocks 52 on the mounting plate 3 are respectively aligned with the two mounting holes 41 on the dust hood body 4. Then, push the dust hood body 4 closer to the mounting plate 3, allowing the fixing blocks 52 to pass through the mounting holes 41. The hole 41 extends into the interior of the dust collector hood body 4, simultaneously causing the irregular groove 531 on the connecting shaft 1 53 at the end of the fixing block 52 to move closer to the locking block 545 at the end of the connecting shaft 2 544 inside the dust collector hood body 4, until the locking block 545 is completely submerged in the irregular groove 531, completing the initial positioning and locking. Afterwards, the operator uses the fixing piece 542 on the knob 541 as the force point to rotate the knob 541 located in the mounting groove 43, rotating it 90 degrees. The rotation of the knob 541 will drive the mounting block 543 connected to it. The connecting shaft 544 and the locking block 545 rotate synchronously. Because the locking block 545 engages with the irregularly shaped slot 531, the connecting shaft 53 and the fixing block 52 also rotate synchronously. After the fixing block 52 rotates, the edge of its circular cross-section tightly presses the outer wall of the dust collector body 4 near the mounting plate 3 into the gap between the fixing block 52 and the mounting plate 3. Thus, the dust collector body 4 is firmly fixed to the mounting plate 3 through two locking mechanisms 5. When it is necessary to disassemble the dust collector body 4 for inspection, cleaning, or replacement... The operator rotates the knob 54190 degrees in the opposite direction, causing the relevant components to move in the opposite direction, so that the fixing block 52 releases its pressure on the outer wall of the dust collector hood body 4. Then, the dust collector hood body 4 is pulled to allow the locking block 545 to disengage from the irregular groove 531, and the fixing block 52 to exit from the mounting hole 41. The dust collector hood body 4 can then be removed from the mounting plate 3. The entire process does not require any additional tools and can be completed by manually rotating the knob 541, achieving quick and convenient operation and improving work efficiency.
