Problems solved by technology

The current sintering furnace generally simply installs valves or pipes at the exhaust hole. Although the gas can be discharged, the amount of exhaust gas cannot be controlled, which often results in excessive exhaust gas, and the pressure in the sintering furnace drops sharply, which is lower than the required pressure. fixed range of

Embodiment 1

[0024] Example 1: Combination figure 1 versus figure 2 A sintering furnace exhaust baffle mechanism 2 with an accurately adjustable opening is shown, which is fixed on the top of the sintering furnace 1 and has a base 4 and a baffle 5, and the base 4 is provided with a row on the top of the sintering furnace 1. The air hole 3 communicates with the through hole 6.

[0025] The core design of the present invention is as follows: the baffle 5 is attached to the surface of the base 4, and the baffle 5 is provided with an adjusting hole 7 that matches the through hole 6 on the base 4. The movement of the plate 5 changes the opening of the through gap with the through hole 6.

[0026] A fixed frame 9 is provided on the baffle 5, and a pull rod 10 is provided on the fixed frame 9. In this embodiment, the baffle 5 is driven by an electric cylinder (not shown in the figure) connected to the pull rod 10 to perform a translational movement on the surface of the base 4. The surface of the b...

Embodiment 2

[0029] Example 2: Such as image 3 The difference between the exhaust baffle mechanism of the sintering furnace shown in Embodiment 1 is that: in this embodiment, there are two through holes 6 on the base 4, and the number of baffles 5 is the same as that of the through holes 6. Correspondingly, there are also two pieces, and the two baffles 5 are fixed on the same fixed frame 9. The center of the fixed frame 9 is connected with a tie rod 10, which is connected to an electric cylinder (not shown in the figure) and is driven by the electric cylinder The two baffles 5 move back and forth synchronously. In addition, the through hole 6 on the base 4 in this embodiment is a conventional round hole. The rest of the design of this embodiment is the same as that of embodiment 1.

Embodiment 3

[0030] Embodiment 3: This embodiment does not give drawings. The difference from Embodiment 1 is that the path groove is an arc-shaped groove, the baffle is provided with a fixed frame, the base is provided with a rotating shaft, and the The rotating shaft and the fixed frame are connected by a connecting piece, and the driving mechanism includes a motor. The output shaft of the motor is connected with the rotating shaft by a gear pair transmission. Therefore, when the motor is started, the output shaft drives the rotating shaft to rotate synchronously, and The rotating shaft drives the baffle to swing back and forth along the arc-shaped groove by the connecting piece, thereby realizing the adjustment of the matching opening between the adjusting hole on the baffle and the through hole on the base. The other design of this embodiment is the same as that of the first embodiment.

Abstract

The invention discloses an exhaust baffle mechanism with the accurately-adjustable opening degree for a sintering furnace. The exhaust baffle mechanism comprises a base and a baffle. A through hole communicating with an exhaust hole in the top of the sintering furnace is formed in the base. The baffle is attached to the surface of the base and driven manually or driven by a driving mechanism to make translational movement, or revolution movement or rotation movement on the surface of the base. An adjusting hole matched with the through hole in the base is formed in the baffle. The matching opening degree of the adjusting hole and the through hole is changed by means of the movement of the baffle. By adopting the exhaust baffle mechanism, the opening degree can be adjusted accurately, accordingly the air displacement of the sintering furnace is controlled accurately, and easy, convenient and labor-saving operation is achieved.

Description

Technical field [0001] The invention belongs to the technical field of the exhaust structure of a sintering furnace, and particularly relates to a sintering furnace exhaust baffle mechanism with an accurately adjustable opening. Background technique [0002] The sintering furnace can sinter various oxide ceramic materials, nitride ceramic materials, carbide ceramic materials and multiphase ceramic materials, which can greatly reduce the firing time, lower the firing temperature, reduce product deformation, increase the yield and save energy Consumption and reduce production costs. In the production process, it is generally necessary to stabilize the temperature and pressure energy parameters in the sintering furnace within a fixed range. However, due to the large amount of gas generated in the high-temperature combustion furnace, the pressure in the furnace continues to increase beyond the fixed range, so the top of the sintering furnace An exhaust hole is provided to discharge ...
