Description

Technical Field

[0001] This utility model relates to the field of sintering furnace technology, specifically a continuous energy-saving sintering furnace device. Background Technology

[0002] A sintering furnace is a furnace used to bond the solid particles of a green material at high temperatures, causing grain growth, reducing porosity (pores) and grain boundaries, and through mass transfer, shrinking the overall volume and increasing the density, ultimately resulting in a dense polycrystalline sintered body with a specific microstructure. It has wide applications in industries such as powder metallurgy and lithium battery manufacturing. The sintering process generally involves heating, holding, and cooling; therefore, horizontal sintering furnaces typically require a transfer device to sequentially pass through the heating, holding, and cooling sections.

[0003] A search revealed that patent application number 201820700817.3 discloses an energy-saving continuous sintering furnace, including a furnace body and a conveying device. The furnace body is equipped with a heating zone, a holding zone, and a cooling zone. The conveying device transports products sequentially through the heating zone, holding zone, and cooling zone. The conveying device is divided into a front conveying device that passes through the heating and holding zones and a rear conveying device that passes through the cooling zone. The rear conveying device operates independently of the front conveying device. A centralized cooling zone is located on the conveying path of the rear conveying device within the cooling zone. After the product is transferred from the front conveying device to the rear conveying device, the rear conveying device quickly moves the product into the centralized cooling zone. This utility model's rear conveying device can quickly bring the product to the centralized cooling zone for rapid cooling, simplifying the cooling mechanism and improving energy efficiency.

[0004] The aforementioned application documents achieve workpiece conveying and subsequent fully automated sintering processing through the setting of multiple sets of conveying components. However, traditional sintering furnaces and their conveying components are all separate structures, resulting in external conveying components at the ends. Firstly, the sealing performance of the sintering furnace is limited. Secondly, traditional conveying components are placed under high temperature conditions for a long time, which reduces their service life.

[0005] Therefore, we propose a continuous energy-saving sintering furnace device. Utility Model Content

[0015] As a preferred embodiment of this utility model, the gap between adjacent conveying plates in the conveying assembly is adapted to the specifications of the teeth on the rotating drum, and the entire conveying assembly is located inside the sintering furnace.

[0016] The gaps between the conveyor plates facilitate the transmission of the outer conveyor components by the rotation of the drum, ensuring the effective conveying of the workpiece.

[0017] As a preferred embodiment of this utility model, the sintering furnace body is composed of a heating zone, a heat preservation zone and a cooling zone that are connected to each other, and a control panel base is also provided on the outside of the sintering furnace body.

[0019] As a preferred embodiment of the present invention, the geared motor is assembled from a drive motor and a reducer on its output end;

[0020] The geared motor, including the drive motor and the reducer, allows for real-time adjustment of the conveying efficiency of the conveying components, enabling them to remain in the heating, holding, and cooling zones for varying durations, thereby further ensuring the sintering process effect.

[0021] This utility model provides a continuous energy-saving sintering furnace device. It has the following beneficial effects:

[0022] This continuous energy-saving sintering furnace device, through the setting of a geared motor on the outside of the sintering furnace body, can install a rotating drum inside, and at the same time, the conveying components are installed inside to ensure the overall sealing effect of the sintering furnace body, further ensuring the sintering effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-5 This utility model provides a technical solution: a continuous energy-saving sintering furnace device, including a sintering furnace body 1 and a conveying assembly 5 assembled inside it. An end cover 2 is sealed at the end of the sintering furnace body 1, and the bottom of the sintering furnace body 1 is stably supported by a bracket 4. A reduction motor 3 is fixedly installed on the outer wall of the sintering furnace body 1, and a rotating drum 6 is mounted on the output shaft of the reduction motor 3 on the inner side of the sintering furnace body 1. Four sets of rotating drums 6 are arranged in opposite positions on the inner side of the sintering furnace body 1, and the conveying assembly 5 is meshed between the four sets of rotating drums 6.

[0031] The continuous energy-saving sintering furnace device, through the setting of the geared motor 3 on the outside of the sintering furnace body 1, can install the rotating drum 6 internally, and at the same time, the conveying component 5 is internally assembled on it, ensuring the overall sealing effect of the sintering furnace body 1, and further ensuring the sintering effect. The setting of the conveying component 5 can use its transmission to transport the workpiece to each furnace body inside the sintering furnace body 1, ensuring the sintering processing effect, and solving the problem that the existing external conveying causes poor sealing of the sintering furnace body 1 and low sintering efficiency.

[0032] Example 2:

[0033] The output shaft of the geared motor 3 is a rotating shaft 31, and the outer end of the rotating shaft 31 of the geared motor 3 passes through the sintering furnace body 1 and is fixedly connected to a rotating drum 6. The geared motor 3 can drive the rotating drum 6 inside the sintering furnace body 1 to rotate through the rotating shaft 31, thereby driving the transmission component 5 inside it to transmit the workpiece to each furnace body inside the sintering furnace body 1.

[0034] The rotating cylinder 6 is a cylindrical seat, and the outer wall of the outer end of the rotating cylinder 6 is provided with a ring of teeth 61; the rotating cylinder 6 is made of ceramic material, and the rotating cylinder 6 is clamped to the inner side of the conveying component 5 by the teeth 61, so as to ensure that it does not deform under high temperature, thereby ensuring its subsequent working state.

[0035] The main body of the conveying component 5 consists of conveying plates 51 arranged at intervals. The inner sides of the conveying plates 51 are connected by a conveying chain 52. Both the conveying plates 51 and the conveying chain 52 are made of silicon carbide material. The use of silicon carbide material ensures that the conveying component 5 does not melt under high temperature, thus ensuring the subsequent conveying effect.

[0036] The gaps between adjacent conveyor plates 51 in the conveying assembly 5 are adapted to the specifications of the toothed teeth 61 on the rotating drum 6, and the entire conveying assembly 5 is located inside the sintering furnace body 1; the gaps between the conveyor plates 51 are designed to facilitate the transmission of the conveying assembly 5 on its outer side by the rotation of the rotating drum 6, ensuring the conveying effect on the workpiece.

[0037] The sintering furnace body 1 consists of a heating zone 11, a heat preservation zone 12, and a cooling zone 13 that are connected to each other. A control panel base 14 is also provided on the outside of the sintering furnace body 1. The arrangement of the heating zone 11, the heat preservation zone 12, and the cooling zone 13 facilitates efficient sintering of the workpieces inside by changing the temperature. The arrangement of the control panel base 14 facilitates fully automatic control and ensures the effect of automated sintering.

[0038] The geared motor 3 is assembled from a drive motor and a reducer on its output end; the drive motor and reducer in the geared motor 3 can adjust the transmission efficiency of the transmission component 5 at any time, so that it stays in the heating zone 11, the heat preservation zone 12 and the cooling zone 13 for different durations, thereby further ensuring the sintering process effect.

[0039] The working principle and usage process of this utility model are as follows: When the device needs to work, the external geared motor 3 drives the built-in rotating drum 6 to rotate, which in turn drives the transmission component 5 mounted on the rotating drum 6 to move, thereby driving the workpiece on it to move inside the sintering furnace body 1. The change of speed of the geared motor 3 can make the workpiece stay in each furnace body inside the sintering furnace body 1 for a corresponding period of time, ensuring the sintering processing effect.
