Description

Technical Field

[0001] This utility model belongs to the technical field of high-temperature purification furnace door, specifically referring to a furnace door opening and closing moving device for a high-temperature purification furnace. Background Technology

[0002] High-temperature furnaces are widely used in sintering processes in ceramics, metallurgy, electronics, glass, chemicals, machinery, refractory materials, new material development, special materials, and building materials. Especially with the expanding range of applications, the use of large-capacity furnaces has become an inevitable trend in order to further reduce unit energy consumption and increase single-furnace output.

[0003] Common high-temperature furnaces have horizontally opening doors, but this occupies a lot of floor space. A search revealed a furnace door opening and closing moving device for a high-temperature purification furnace, which enables the furnace door to be opened by rotation. However, it still has shortcomings in use: it cannot guarantee a tight seal between the furnace door and the high-temperature furnace, and the rotation opening still occupies a certain amount of floor space. Therefore, improvements are needed. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the opening method of the furnace door in the existing high-temperature purification furnace occupies ground space, and the furnace door cannot guarantee a good seal when it is closed with the furnace body.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: A furnace door opening and closing moving device for a high-temperature purification furnace includes a high-temperature purification furnace. The upper end of the high-temperature purification furnace is provided with a fixed plate. A top groove is provided in the fixed plate. A slider is slidably provided in the top groove. A sealing and pushing device is provided in the slider and the top groove. A furnace door is provided on one side of the high-temperature purification furnace and is connected to the sealing and pushing device. A rotating device is provided on the slider and the furnace door. The rotating device includes a hinge seat. The hinge seat is provided on the lower end face of the slider. A hydraulic cylinder is hinged to the hinge seat. A vertical groove is provided in the furnace door. A sliding seat is slidably provided in the vertical groove. The output end of the hydraulic cylinder is hinged to the sliding seat. By pulling the sliding seat with the hydraulic cylinder, the furnace door can be rotated, thereby enabling the furnace door to open upward and reducing the space occupied on the ground.

[0006] Furthermore, the sealing push device includes a second hydraulic cylinder, which is located in the top groove and its output end is connected to the slider. The slider is provided with a vertical plate, and a connecting plate is rotatably provided in the vertical plate via a shaft. The connecting plate is fixedly connected to the furnace door. When the second hydraulic cylinder pulls the slider, the furnace door can be pressed against the end face of the high-temperature purification furnace to achieve sealing and closure.

[0007] Preferably, the slider is provided with ear plates on both sides, and the ear plates slide in the side wall of the top groove. The ear plates can prevent the slider from falling out of the top groove.

[0008] Preferably, the sliding seat is slidably attached to the vertical groove.

[0009] Preferably, the length of the top groove is sufficient to ensure that the furnace door fits against the high-temperature purification furnace when the slider slides in the top groove.

[0010] Preferably, two sets of vertical plates are symmetrically arranged on the slider, and the distance between the two sets of vertical plates is equal to the width of the connecting plate.

[0011] The beneficial effects achieved by adopting the above-described structure are as follows:

[0012] 1. This utility model, by setting a rotating device, allows the hydraulic cylinder to pull the sliding seat to slide in the vertical groove, while the base of the hydraulic cylinder rotates on the hinge seat, thereby enabling the furnace door to be pulled and rotated, allowing the furnace door to rotate upward and open, reducing the space occupied.

[0013] 2. This utility model uses a sealing and pushing device. The hydraulic cylinder pulls the slider to slide in the top groove. The slider drives the furnace door to move closer to the high-temperature purification furnace until it is tightly sealed on the high-temperature purification furnace. Attached Figure Description

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Therefore, they should not be construed as limitations on this utility model.

[0021] like Figure 1-4 This utility model discloses a furnace door opening and closing moving device for a high-temperature purification furnace, comprising a high-temperature purification furnace 1, a fixed plate 2 at the upper end of the high-temperature purification furnace 1, a top groove 3 in the fixed plate 2, a slider 4 slidably disposed in the top groove 3, ear plates 15 on both sides of the slider 4, the ear plates 15 sliding in the side wall of the top groove 3, the ear plates 15 are provided to prevent the slider 4 from falling out of the top groove 3, the length of the top groove 3 is sufficient to ensure that the furnace door 6 is attached to the high-temperature purification furnace 1 when the slider 4 slides in the top groove 3, a sealing and pushing device 5 is provided in the slider 4 and the top groove 3, a furnace door 6 is provided on one side of the high-temperature purification furnace 1 and is connected to the sealing and pushing device 5, and a rotating device 7 is provided on the slider 4 and the furnace door 6.

[0022] like Figure 1-3 The rotating device 7 includes a hinge seat 8, which is located on the lower end face of the slider 4. A hydraulic cylinder 9 is hinged to the hinge seat 8. The furnace door 6 has a vertical groove 10 inside, and a sliding seat 11 slides in the vertical groove 10. The sliding seat 11 slides in the vertical groove 10 in a snap-fit ​​manner. The output end of the hydraulic cylinder 9 is hinged to the sliding seat 11. By pulling the sliding seat 11 with the hydraulic cylinder 9, the furnace door 6 can be rotated, thereby enabling the furnace door 6 to open upward and reducing the space occupied on the ground.

[0023] like Figure 1 , 2 4. The sealing push device 5 includes a second hydraulic cylinder 12, which is located in the top groove 3 and its output end is connected to the slider 4. The slider 4 is provided with a vertical plate 13, and a connecting plate 14 is rotatably provided in the vertical plate 13 via a shaft. Two sets of vertical plates 13 are symmetrically arranged on the slider 4, and the distance between the two sets of vertical plates 13 is equal to the width of the connecting plate 14. The connecting plate 14 is fixedly connected to the furnace door 6. When the second hydraulic cylinder 12 pulls the slider 4, the furnace door 6 can be pressed against the end face of the high-temperature purification furnace 1 to achieve sealing and closure.

[0024] In practical use, when it is necessary to open the furnace door 6, firstly, the slider 4 is pushed by the hydraulic cylinder 2 12 to slide in the top groove 3. The slider 4 drives the furnace door 6 to move away from the high temperature purification furnace 1. After moving to a certain distance, the hydraulic cylinder 1 9 is activated. The hydraulic cylinder 1 9 pulls the sliding seat 11 to slide in the vertical groove 10. The connecting plate 14 at the upper end of the furnace door 6 will rotate in the vertical plate 13. In this way, the furnace door 6 will flip up and open, which will save the space occupied on the ground.

[0025] When closing the furnace door 6, first rotate the furnace door 6 to a vertical position, and then use hydraulic cylinder 2 12 to pull the slider 4 closer to the high-temperature purification furnace 1 until the furnace door 6 is tightly fitted onto the high-temperature purification furnace 1, thus achieving a sealed closure of the furnace body.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto.
