Description

Technical Field

[0001] This utility model relates to the field of vacuum oil quenching furnace technology, and in particular to a cooling device for a vacuum oil quenching furnace. Background Technology

[0002] Vacuum heat treatment furnaces are commonly used industrial casting and heat treatment equipment. However, current vacuum oil quenching furnaces often lack devices to control the temperature of the cooling oil. As a result, uneven cooling rates, insufficient hardness, and sometimes excessively rapid cooling rates can occur during the quenching process. These issues can lead to cracking or excessive deformation of the workpiece.

[0003] A vacuum oil quenching furnace is disclosed in patent application CN 206529503 U. It features an oil inlet and outlet in an oil storage chamber connected by an oil pipeline. This pipeline includes a main oil supply line and parallel cooling and heating branches. A quenching oil cooling device is installed on the cooling branch, and a quenching oil heating device is installed on the heating branch. A temperature sensing element is installed in the oil storage chamber to measure the temperature of the quenching oil in real time. Based on the measured oil temperature and a preset heat treatment process, the quenching oil is directed to either the cooling or heating branch to adjust its temperature, ensuring it meets process requirements. This vacuum oil quenching furnace achieves temperature regulation, improving the quality of processed workpieces.

[0004] However, in the existing technology, the system used to cool quenching oil is relatively complex and requires regular maintenance and upkeep by operators, resulting in a large workload for operators. Utility Model Content

[0005] The purpose of this invention is to provide a cooling device for a vacuum oil quenching furnace, which aims to solve the problem that the existing systems for cooling quenching oil are relatively complex and require regular maintenance and upkeep by operators, resulting in a large workload for operators.

[0006] To achieve the above objectives, this utility model provides a cooling device for a vacuum oil quenching furnace, comprising a furnace body and a cooling mechanism. The cooling mechanism includes a cooling pipe, an inlet pipe, an outlet pipe, a water pump, a storage tank, a cooling component, and a heat insulation cover. The cooling pipe is fixedly connected to the furnace body and located on the outer wall of the furnace body. The inlet pipe is fixedly connected to one end of the cooling pipe and communicates with it. The outlet pipe is fixedly connected to the end of the cooling pipe away from the inlet pipe and communicates with it. One end of the inlet pipe and the outlet pipe extends into the storage tank. The cooling component is disposed in the storage tank. The water pump is disposed on the inlet pipe. The heat insulation cover is fixedly connected to the outer wall of the furnace body, and the cooling pipe is located inside the furnace body.

[0007] The cooling component includes a cooler and a thermometer. The cooler is fixedly connected to the storage box and located inside the storage box, and the thermometer is fixedly connected to the storage box.

[0008] The cooling mechanism further includes a cover plate, which is fixedly connected to the storage tank and located above the storage tank. One end of the liquid inlet pipe and one end of the liquid outlet pipe pass through the cover plate.

[0009] The cooling mechanism further includes a fixing component, which is disposed between the cooling pipe and the liquid outlet pipe.

[0010] The fixing assembly includes a fixing ring, a fastening bolt, and a fastening nut. One end of the liquid outlet pipe and the cooling pipe are located inside the fixing ring. The fastening bolt is threaded to one end of the fixing ring, and the fastening nut is threaded to one end of the fastening bolt.

[0011] This utility model discloses a cooling device for a vacuum oil quenching furnace. When using this device to cool the quenching oil inside the furnace, the water pump is activated, drawing coolant from the storage tank into the inlet pipe. The coolant moves within the cooling pipe, and the insulation cover isolates the cooling pipe from the outside environment, preventing the coolant from absorbing external heat and rising in temperature. This ensures that the coolant only absorbs heat from the furnace body, causing the quenching oil temperature inside the furnace to drop. Simultaneously, the coolant, having absorbed heat from the furnace body, rises in temperature. The heated coolant then enters the storage tank through the outlet pipe, where a cooling component cools it back to an appropriate temperature. This cycle cools the quenching oil inside the furnace. The device has a simple structure and is easy to maintain, thus reducing the workload of operators. Attached Figure Description

[0019] This utility model provides a cooling device for a vacuum oil quenching furnace, including a furnace body 101 and a cooling mechanism. The cooling mechanism includes a cooling pipe 104, an inlet pipe 102, a fixing component, a cover plate 112, an outlet pipe 105, a water pump 103, a storage tank 106, a cooling component, and a heat insulation cover 108. The cooling component includes a cooler 113 and a thermometer 107. The fixing component includes a fixing ring 109, a fastening bolt 110, and a fastening nut 111. The aforementioned solution solves the problem in the prior art that the system for cooling quenching oil is relatively complex and requires regular maintenance and upkeep by operators, resulting in a large workload for operators.

[0020] In this embodiment, the cooling pipe 104 is fixedly connected to the furnace body 101 and located on the outer wall of the furnace body 101. The liquid inlet pipe 102 is fixedly connected to one end of the cooling pipe 104 and they are in communication. The liquid outlet pipe 105 is fixedly connected to the end of the cooling pipe 104 away from the liquid inlet pipe 102 and they are in communication. One end of the liquid inlet pipe 102 and the liquid outlet pipe 105 extends into the storage tank 106. The cooling assembly is disposed in the storage tank 106. The water pump 103 is disposed on the liquid inlet pipe 102. The heat insulation cover 108 is fixedly connected to the outer wall of the furnace body 101, and the cooling pipe 104 is located inside the furnace body 101. When using this device to cool the quenching oil inside the furnace body 101, the water pump 103 is started. 3. The coolant in the storage tank 106 is drawn into the inlet pipe 102. The coolant moves within the cooling pipe 104. The insulation cover 108 isolates the cooling pipe 104 from the outside environment, preventing the coolant in the cooling pipe 104 from absorbing external temperature and rising in temperature. This ensures that the coolant only absorbs heat from the furnace body 101, causing the quenching oil temperature in the furnace body 101 to drop. Simultaneously, the coolant absorbs heat from the furnace body 101 and rises in temperature. The heated coolant then enters the storage tank 106 through the outlet pipe 105. The cooling component cools the heated coolant back to an appropriate temperature. This cycle can cool the quenching oil in the furnace body 101. The device has a simple structure and is easy to maintain, thus reducing the workload of operators.

[0021] Furthermore, the cooler 113 is fixedly connected to the storage box 106 and located inside the storage box 106, and the thermometer 107 is fixedly connected to the storage box 106.

[0022] In this embodiment, when using the device to cool the quenching oil inside the furnace body 101, the water pump 103 is started. The water pump 103 draws the coolant from the storage tank 106 into the inlet pipe 102. The coolant moves within the cooling pipe 104. The heat insulation cover 108 isolates the cooling pipe 104 from the outside environment, preventing the coolant in the cooling pipe 104 from absorbing external heat and rising in temperature. This ensures that the coolant only absorbs heat from the furnace body 101, causing the temperature of the quenching oil inside the furnace body 101 to drop. Simultaneously, the coolant absorbs the heat from the furnace body 101. The furnace body 101 is heated to a higher temperature. The heated coolant then enters the storage tank 106 through the outlet pipe 105. The coolant is then cooled back to a suitable temperature by the cooler 113. The thermometer 107 measures the temperature of the coolant in the storage tank 106, and the cooler 113 is switched on and off to maintain the coolant within a suitable temperature range. This cycle can cool the quenching oil in the furnace body 101. The device has a simple structure and is easy to maintain, thus reducing the workload of the operators.

[0023] Furthermore, the cover plate 112 is fixedly connected to the storage tank 106 and is located above the storage tank 106, and one end of the liquid inlet pipe 102 and one end of the liquid outlet pipe 105 pass through the cover plate 112.

[0024] In this embodiment, the cover plate 112 seals the storage tank 106, isolating the outside world from the inside of the storage tank 106, and preventing the coolant temperature from rising.

[0025] Furthermore, the fixing component is disposed between the cooling pipe 104 and the liquid outlet pipe 105.

[0026] Furthermore, one end of the liquid outlet pipe 105 and the cooling pipe 104 are located inside the fixing ring 109, the fastening bolt 110 is threadedly connected to one end of the fixing ring 109, and the fastening nut 111 is threadedly connected to one end of the fastening bolt 110.

[0027] In this embodiment, the fixing ring 109 is located at the connection between the cooling pipe 104 and the liquid outlet pipe 105. The fixing ring 109, the fastening bolt 110 and the fastening nut 111 can enhance the connection strength between the cooling pipe 104 and the liquid outlet pipe 105, ensuring that no coolant will flow out at the connection between the cooling pipe 104 and the liquid outlet pipe 105, thereby improving the structural stability of the device.

[0028] When using this invention to cool the quenching oil in the furnace body 101, the water pump 103 is started. The water pump 103 draws the coolant from the storage tank 106 into the inlet pipe 102. The coolant moves within the cooling pipe 104. The heat insulation cover 108 isolates the cooling pipe 104 from the outside environment, preventing the coolant in the cooling pipe 104 from absorbing external temperature and rising in temperature. This ensures that the coolant only absorbs heat from the furnace body 101, causing the quenching oil temperature in the furnace body 101 to drop. Simultaneously, the coolant absorbs heat from the furnace body 101 and rises in temperature. The heated coolant then enters the storage tank 106 through the outlet pipe 105. The cooling component cools the heated coolant back to an appropriate temperature. This cycle can cool the quenching oil in the furnace body 101. The device has a simple structure and is easy to maintain, thus reducing the workload of operators.
