Description

Technical Field

[0001] This utility model relates to the field of sintering furnaces, and in particular to a cooling and temperature-reducing device for sintering furnaces. Background Technology

[0002] Sintering furnaces are equipment used in high-temperature sintering processes and are widely used in metal powder metallurgy, ceramic sintering, and electronic component manufacturing. During the sintering process, the interior of the sintering furnace usually needs to maintain a high-temperature environment to ensure that the physical and chemical properties of the material meet the expected requirements. However, after high-temperature sintering is completed, in order to ensure product quality and long-term stable operation of the equipment, the sintering furnace must be cooled down so that the product can be stably formed within a suitable temperature range. At the same time, it is necessary to avoid thermal fatigue, material deformation, or equipment damage caused by the furnace body and internal components being in a high-temperature state for a long time.

[0003] In the existing technology, traditional cooling systems often fail to fully recycle cooling water when cooling sintering furnaces, which can easily lead to resource waste and increased operating costs. In addition, traditional cooling systems are also prone to uneven cooling and low cooling efficiency, which can affect the stability and service life of the equipment.

[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0010] The liquid outlet of the plate heat exchanger is connected to the cooling chamber through the first liquid inlet pipe. The first water pump is installed on the first liquid inlet pipe to return the cooling water cooled by the plate heat exchanger to the cooling chamber.

[0011] The cooling tank is used to store cooling fluid. The cooling tank is connected to the plate heat exchanger through cooling pipes. The cooling tank is used to input cooling fluid into the plate heat exchanger to absorb heat from the cooling water in the plate heat exchanger.

[0013] The cooling and temperature reduction device of the sintering furnace using the above technical solution also includes a circulation pipeline and a second water pump.

[0014] The first end of the circulation pipe is connected to the side wall of the sintering furnace body, and the second end of the circulation pipe is connected to the top wall of the sintering furnace body. The second water pump is installed on the circulation pipe and is used to transport the cooling water at the lower level of the cooling chamber to the higher level.

[0018] In the above technical solution, the cooling and temperature reduction device of the sintering furnace is provided with a flow control valve on the cooling pipe, and the flow control valve is used to adjust the flow rate of the cooling fluid.

[0019] The cooling device for the sintering furnace using the above technical solution also includes a controller. The temperature sensor is electrically connected to the controller, and the controller is used to adjust the operation of the first water pump and the electric valve according to the cooling water temperature detected by the temperature sensor.

[0021] The sintering furnace body of this invention has a cooling chamber inside. A temperature sensor can detect the temperature of the cooling water in the cooling chamber in real time.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1 to 4As shown, this utility model embodiment provides a cooling device for a sintering furnace, including a frame 1, a sintering furnace body 2, a temperature sensor 3, a plate heat exchanger 4, a cooling box 5, a heat exchange tube assembly 6, and a drain pipe assembly 7. The sintering furnace body 2 is mounted on the frame 1, and has a cooling chamber inside. A water supply pipe 21 is provided on the side wall of the sintering furnace body 2, and the water supply pipe 21 communicates with the cooling chamber. The water supply pipe 21 is used to supply cooling water to the cooling chamber. The temperature sensor 3 is located inside the sintering furnace body 2 and is used to detect the temperature of the cooling water in the cooling chamber. The heat exchanger tube assembly 6 includes a first outlet pipe 61, an electric valve 62, a first water pump 63, and a first inlet pipe 64. The bottom of the cooling chamber is connected to the inlet end of the plate heat exchanger 4 via the first outlet pipe 61. The electric valve 62 is mounted on the first outlet pipe 61 and is used to control the opening and closing of the first outlet pipe 61. The outlet end of the plate heat exchanger 4 is connected to the cooling chamber via the first inlet pipe 64. The first water pump 63 is mounted on the first inlet pipe 64 to return the cooling water cooled by the plate heat exchanger 4 to the cooling chamber. The cooling tank 5 is used to store cold water. The cooling tank 5 is connected to the plate heat exchanger 4 via a cooling pipe 51. The cooling tank 5 is used to input cooling fluid into the plate heat exchanger 4 to absorb the heat of the cooling water inside the plate heat exchanger 4. During the cooling process of the sintering furnace, cooling water is input into the cooling chamber inside the sintering furnace body 2 through the water supply pipe 21 to absorb the heat of the sintering furnace body 2 and reduce its temperature. The temperature sensor 3 can detect the temperature of the cooling water in the cooling chamber in real time. When the water temperature rises to a set threshold, the electric valve 62 opens, and the cooling water is transported to the plate heat exchanger 4 through the first liquid outlet pipe 61 at the bottom of the cooling chamber. During the heat exchange process, the heat of the cooling water is transferred to the cooling fluid from the cooling tank 5 through the plate heat exchanger 4, thereby completing the cooling of the cooling water. Subsequently, the first water pump 63 can transport the cooled cooling water back to the cooling chamber through the first liquid inlet pipe 64, thereby realizing the recycling of cooling water. The setting of the cooling tank 5 can avoid the mixing of the two fluids, thereby improving the cooling efficiency of the sintering furnace body 2 and reducing the maintenance difficulty. The entire cooling system can realize the recycling of cooling water, the efficient heat absorption of cooling fluid, and the intelligent control of the cooling process, which not only optimizes the cooling effect, but also saves resources and enhances the reliability and operating efficiency of the equipment.

[0032] The drain pipe assembly 7 is located at the bottom of the sintering furnace body 2 and is used to drain the cooling water in the cooling chamber. The drain pipe assembly 7 allows for the periodic drainage and replacement of the cooling water in the cooling chamber, preventing impurities, sediments, or other contaminants from entering the cooling water and affecting the cooling effect.

[0033] like Figure 3As shown, further, it also includes a circulation pipe 81 and a second water pump 82. The first end of the circulation pipe 81 is connected to the side wall of the sintering furnace body 2, and the second end of the circulation pipe 81 is connected to the top wall of the sintering furnace body 2. The second water pump 82 is installed on the circulation pipe 81 and is used to transport the cooling water from the lower level of the cooling chamber to the higher level. This arrangement can realize the vertical circulation of cooling water, allowing the cooling water to circulate throughout the entire cooling chamber, improving the fluidity of the cooling water, thereby improving the cooling efficiency and avoiding the problem of local overheating.

[0034] like Figure 1 and Figure 4 As shown, the drain pipe assembly 7 further includes a main drain pipe 71, a third water pump 72, a first drain branch pipe 73, and a second drain branch pipe 74. The main drain pipe 71 is connected to the bottom of the sintering furnace body 2. The first end of the first drain branch pipe 73 is connected to the main drain pipe 71, the second end of the first drain branch pipe 73 is connected to the inlet end of the third water pump 72, and the outlet end of the third water pump 72 is connected to the second drain branch pipe 74. When it is necessary to drain the cooling water in the cooling chamber, the third water pump 72 starts, thereby drawing the cooling water in the main drain pipe 71 through the first drain branch pipe 73 to the second drain branch pipe 74 for discharge. In this embodiment, there are two sets of third water pumps 72. This ensures that if one set of pumps fails, the other set can continue to work as a backup, avoiding interruption of the draining process and improving the operational reliability of the equipment.

[0035] like Figure 4 As shown, the cooling pipe 51 is further equipped with a flow control valve 52, which is used to regulate the flow rate of the cooling fluid. During the heat absorption and cooling process of the cooling water, the flow control valve 52 can adjust its opening based on the information fed back by the temperature sensor 3. When the cooling water temperature is high, the flow control valve 52 can increase the flow rate of the cooling fluid, thereby accelerating heat transfer; when the cooling water temperature is low, it can reduce the flow rate of the cooling fluid to avoid wasting resources. This setting allows the cooling system to dynamically adjust the flow rate according to the operating conditions, thereby improving the adaptability of the cooling system, optimizing resource utilization, and reducing operating costs.

[0036] Furthermore, the system also includes a controller. The temperature sensor 3 is electrically connected to the controller, which adjusts the operation of the first water pump 63 and the electric valve 62 based on the cooling water temperature detected by the temperature sensor 3. When the temperature sensor 3 detects that the cooling water temperature has risen to a set threshold, the controller can increase the opening of the electric valve 62, thereby increasing the discharge flow rate of cooling water at the bottom of the cooling chamber. At the same time, the first water pump 63 is activated to return more cooled cooling water to the cooling chamber to accelerate cooling. This achieves intelligent and automated management of the cooling process, thereby optimizing cooling efficiency and improving the stability of system operation.

[0037] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
