EMBODIMENT

[0031] The present embodiment provides a furnace cover, referring to Figure 2 , which shows the overall display diagram of the furnace cover, from which it can be seen that it comprises a cover assembly and a frame assembly 6, the frame assembly 6 is used to be connected at the inlet of the sintering furnace, the frame assembly 6 and the inlet of the furnace form communication and are used for the passing of raw materials; the cover assembly is used to be connected on the frame assembly 6 and is used to block the passage of the frame assembly 6.

[0032] Specifically, refer to Figure 3 , as shown in the figure, the cover assembly includes a blocking body 1, the upper side of the blocking body 1 is formed with a first adsorption area 2, the lower side of the blocking body 1 is formed with a shielding part, and four corners of the shielding part are respectively formed with moving feet 3; the first adsorption area 2 is provided with a lifting assembly above, the output end of the lifting assembly is connected with an adsorption block 4, the lifting assembly is used to drive the adsorption block 4 to approach the first adsorption area 2, and the adsorption block 4 and the first adsorption area 2 generate mutual attraction force when approaching; the right end upper surface of the blocking body 1 is provided with a locking mechanism 5.

[0033] Specifically, refer to Figure 4 , as shown in the figure, the frame assembly 6 includes a cylinder body 601, one end of the cylinder body 601 is used to communicate with the feeding furnace opening on the hearth 13, the other end of the cylinder body 601 is connected with a frame 602, the inner side edge of the frame 602 is formed with a circle of grooves 603, the front and rear sides of the upper end of the grooves 603 are respectively formed with two openings 604; the outer edge of the right side of the frame 602 is connected with a locking groove 605.

Note that the adsorption force generated on the adsorption block 4, the first adsorption area 2, the second adsorption area and the third adsorption area is generated by an electromagnet, which is a common prior art on the market, and is not shown in the drawing.

[0035] Refer to Figure 2When the cover assembly and the frame assembly 6 are combined together, the four moving feet 3 of the blocking body 1 are respectively corresponding to the four openings 604 on the trench 603; when the four moving feet 3 are put into the four openings 604, the right end surface of the right end moving foot 3 has a gap with the inner wall surface of the right side of the trench 603; after the four moving feet 3 are put into the four openings 604, due to the difference in the size of the adsorption force generated between the adsorption block 4 and the first adsorption area 2 and the adsorption force generated between the second adsorption area and the third adsorption area, the right side of the trench 603 adsorbs the moving foot 3 to itself; when the second adsorption area on the right side of the moving foot 3 approaches the third adsorption area of the trench 603, the locking mechanism 5 on the blocking body 1 gradually flips to one side of the locking groove 605; after the second adsorption area on the right side of the moving foot 3 approaches the third adsorption area of the trench 603, the locking mechanism 5 is locked with the locking groove 605. After the locking mechanism 5 and the locking groove 605 are locked, the electromagnet can be powered off, and the adsorption force between the adsorption block 4 and the first adsorption area 2 and between the second adsorption area and the third adsorption area does not need to be continuously generated. When the cover needs to be opened, the locking mechanism 5 and the locking groove 605 only need to be unlocked.

[0037] The working principle of the locking mechanism 5 is as follows: Figure 6, it can be seen from the figure that: in the first case, when the cover needs to be closed, the blocking body 1 is close to the adjacent edge of the frame 602 under the action of magnetic attraction (in the a direction), and the blocking body 1 moves in the a direction, which drives the gear 503 to move; under the joint restriction of the blocking body 1 and the toothed plate 8, the gear 503 is flipped in the direction of the locking groove 605 (in the b direction); until the moving foot 3 below the blocking body 1 is attached to the adjacent groove 603, the locking groove 605 is used to lock the horizontal shaft of the curved shaft 501; finally, the electromagnets acting on the second and third adsorption regions are powered off. In the second case, when the cover needs to be opened, the pawl 506 is unlocked from the ratchet wheel 505, the spring 7 pulls the gear 503 to return; the gear 503 moves in the opposite direction of the a direction on the toothed plate 8, and the curved shaft 501 flips and moves in the opposite direction of the a direction; finally, the horizontal shaft of the curved shaft 501 is separated from the locking groove 605, and the blocking body 1 and the moving foot 3 on the blocking body 1 move back to the original position, and the moving foot 3 and the corresponding opening 604 on the groove 603 are re-formed. At this time, the adsorption block 4 is placed in the first adsorption region 2 again by starting the lifting assembly, and the magnetic attraction between the adsorption block 4 and the first adsorption region 2 is generated by using the electromagnet, and the lifting assembly is started to lift the blocking body 1.

[0038] The present application can lock the blocking body 1 on the material inlet furnace mouth by combining the locking mechanism 5 and the locking groove 605; the present application can realize rapid separation and closing between the blocking body 1 and the material inlet furnace mouth by combining the adsorption force between the adsorption block 4 and the first adsorption region 2 and the lifting assembly; the present application can complete the rapid locking action between the locking mechanism 5 and the locking groove 605 by combining the adsorption force between the second adsorption region and the third adsorption region, and the working efficiency is improved; compared with the prior art, the present application can automatically open and close the cover without relying on manpower, which eliminates the problem of scalding of workers and avoids the problem of fatigue of workers.

[0039] Further, to ensure that the pawl 506 and the ratchet wheel 505 can be smoothly unlocked, the present application designs an unlocking mechanism; specifically, Figure 7 , the use state diagram of the gate wire 10 and the gate handle 9 is shown, and it can be seen from the figure that the unlocking mechanism includes the gate handle 9, the gate handle 9 is connected with the gate wire 10, and the free end of the gate wire 10 is connected with the pawl 506. When unlocking is needed, the pressure rod on the gate handle 9 is squeezed in the c direction, so that the gate wire 10 is retracted into the cavity of the gate handle 9, and the pawl 506 is pulled away from the ratchet wheel 505.

[0040] Further, after the lifting assembly removes the blocking body 1 from the charging furnace mouth, the lifting assembly and the blocking body 1 need to be adjusted to other appropriate positions for placement to avoid the cover body from blocking the discharging; therefore, the application designs an adjusting mechanism 11; specifically, as Figure 8 shown in the installation structure diagram of the adjusting mechanism 11, it can be seen from the diagram that the adjusting mechanism 11 comprises a sliding rail 1101, a seat body 1102 is slidingly connected in the sliding channel of the sliding rail 1101, screw holes are formed in the bottom of the seat body 1102, screw rods 1103 are threadedly assembled in the screw holes, and both ends of the screw rods 1103 are connected to both ends of the sliding rail 1101; a pin column 1104 is rotatably connected to the seat body 1102, and a ring frame 1105 for embracing the lifting assembly is connected to the pin column 1104; a servo motor is bolted to the seat body 1102, the output shaft of the servo motor is connected to the pin column 1104 through a belt, and the power generated by the servo motor is transmitted to the pin column 1104 through the belt.
