Description

Technical Field

[0001] The utility model relates to the technical field of exhaust structures, and particularly relates to an exhaust gas regulating device for a sintering furnace. Background Art

[0002] A sintering furnace is a special device that enables powder compacts to obtain the required physical and mechanical properties as well as microstructures through sintering. The sintering furnace is used to dry the slurry on the silicon wafer, remove the organic components in the slurry, and complete the sintering of the aluminum back field and grid lines. The exhaust structure of the sintering furnace mainly includes an exhaust system, which is one of the important components of the sintering furnace and is designed to discharge the flue gas and waste gas generated in the furnace chamber to ensure the stability of the atmosphere in the furnace chamber. The design and implementation of the exhaust system are crucial for the success of the sintering process because it directly affects the control of the oxygen content during the sintering process, thereby affecting the product quality. The basic composition of the exhaust system includes an exhaust pipe, which is connected to the exhaust pipe of the sintering furnace and is internally provided with cylindrical filter bags. These filter bags are used to capture and filter the particulate matter in the flue gas to prevent environmental pollution and also protect the normal operation of the sintering furnace.

[0003] In the prior art, a regulating valve is generally provided at the outlet of the exhaust system. Adjusting the opening degree of the regulating valve requires personnel to climb to the top of the furnace body for adjustment. The temperature at the top of the furnace body is very high, the personnel operating environment is extremely harsh, and the work at height is very dangerous. At the same time, the regulating valve generally has no scale indication for showing the opening degree of the regulating valve, and it is impossible to accurately adjust the exhaust gas volume of the sintering furnace, resulting in inaccurate control of the atmosphere in the furnace and thus affecting the product quality. Aiming at solving the problems existing in the prior art, an exhaust gas regulating device for a sintering furnace is proposed. Content of the Utility Model

[0023] The following combines specific embodiments to further elaborate on the content of the present utility model:

[0024] In the description of the utility model, it should be understood that the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the utility model.

[0025] As Figure 1 、 Figure 2 shown, an exhaust gas regulating device for a sintering furnace includes: an exhaust chimney 1 installed at the top of the sintering furnace and an exhaust gas regulating mechanism for controlling the flow rate of the gas discharged from the exhaust chimney 1; there can be multiple exhaust chimneys 1, and multiple exhaust chimneys 1 converge to the furnace body exhaust main pipe 2; an exhaust gas regulating mechanism for controlling the flow rate of the discharged gas is provided in each exhaust chimney 1.

[0026] As Figure 3 、 Figure 4As shown in the figure, the exhaust gas regulating mechanism includes a sluice valve installed on the exhaust chimney 1. The sluice valve includes a valve plate 3 and a valve body, and the movement of the valve plate 3 inside the valve body is controlled by a driving assembly. The driving assembly includes a gear-rack module and an adjusting handle. The gear-rack module includes a gear 4 and a rack 5 meshing with the gear 4, and the adjusting handle drives the gear 4 to rotate in place. A dial 6 is sleeved on the outer periphery of the adjusting handle to indicate the rotation angle of the adjusting handle, and a pointer 7 is fixedly installed on the adjusting handle. The adjusting handle includes a connecting rod 8 fixedly connected to the gear 4 and a handle part 12 connected to the connecting rod 8. The connecting rod 8 is installed on a base 9 through a bearing. Further, the dial 6 is sleeved on the outer periphery of the connecting rod 8 (there is no connection relationship between the dial 6 and the connecting rod 8), and the dial 6 and the pointer 7 are located at one end of the connecting rod 8 where the adjusting handle is located. A frame 10 is installed on the side of the sintering furnace in the width direction. A support frame 11 is installed on the frame 10. The connecting rod 8 is erected on the support frame 11, and the dial 6 is fixed on the support frame 11. The setting of the frame 10 is to match the length of the connecting rod 8. The connecting rod 8 is as long as possible, so that the worker can be as far away from the sintering furnace as possible when turning the handle part 12, avoiding scalding or being baked by high temperature. The pointer 7 is located between the support frame 11 and the handle part 12 and in front of the dial 6. This setting facilitates the worker to see the angle of rotation of the pointer 7 relative to the dial 6 when turning the handle part 12. The rack 5 is installed on the bottom surface of the valve plate 3, and the rack 5 is located above the gear 4. The length direction of the rack 5 is perpendicular to the axial direction of the connecting rod 8, and the axial direction of the connecting rod 8 is the same as the axial direction of the gear 4; the axial direction of the connecting rod 8 is parallel to the width direction of the sintering furnace; this setting greatly saves the installation space of the exhaust gas regulating mechanism on the sintering furnace.

[0027] The working principle of an exhaust gas regulating device for a sintering furnace in the present utility model is as follows: when it is necessary to adjust the flow rate of the exhaust gas discharged from the exhaust chimney 1, turn the handle part 12, which drives the gear 4 to rotate in place. Since the gear 4 meshes with the rack 5, the gear 4 rotates in place and drives the rack 5 to move along its length direction, and then drives the valve plate 3 fixed on the rack 5 to move inside the valve body, thereby realizing the adjustment of the flow rate of the exhaust gas discharged from the exhaust chimney 1; at the same time, the pointer 7 rotates with the connecting rod 8, and the flow rate of the exhaust gas discharged from the exhaust chimney 1 can be accurately controlled by the angle of rotation of the pointer 7 relative to the dial 6.

[0028] The above embodiments are only for illustrating the technical concept and features of the present utility model, and the purpose is to enable those who are familiar with this technology to understand the content of the present utility model and implement it accordingly. It is not intended to limit the protection scope of the present utility model.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
