Description

Technical Field

[0001] This utility model relates to the technical field of chain annealing furnaces, specifically to a cooling structure for a chain annealing furnace. Background Technology

[0002] A rapid annealing furnace is a commonly used heat treatment equipment. Its working principle is to anneal materials by heating at high temperatures and cooling them rapidly to improve their properties and microstructure. The cooling stage is an important step in the rapid annealing furnace. After the heating stage, the temperature inside the furnace cavity needs to be rapidly cooled to room temperature to prevent the material from undergoing grain growth and phase transformation again.

[0003] The cooling structure of a chain annealing furnace generally cools the workpiece by spraying. However, water is not easily recycled during spraying, which can easily lead to water waste during the use of the cooling structure. Furthermore, the cooling structure of a chain annealing furnace generally only uses one cooling method to cool the workpiece, which results in a relatively slow cooling rate and a long cooling time required during the use of the cooling structure. Utility Model Content

[0004] The purpose of this invention is to provide a cooling structure for a chain annealing furnace to solve the problems mentioned in the background art, such as the waste of water resources and the long cooling time required.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cooling structure for a chain annealing furnace, comprising a cooling box, a control key installed on the surface of the cooling box, a spray pipe frame fixed to the top of the cooling box by a bracket, a water tank fixed to the bottom of the cooling box, a drain pipe fixed to the bottom of the water tank, a valve installed on the surface of the drain pipe, inlet and outlet openings on both sides of the cooling box, a water circulation mechanism provided inside the cooling box, the water circulation mechanism consisting of a baffle and a water circulation component, and an air cooling mechanism provided on one side of the cooling box, the air cooling mechanism including a discharge rack and air cooling components.

[0006] Preferably, the surface of the cooling box is rotatably connected to a baffle, and the interior of the cooling box is equipped with a water circulation assembly.

[0007] Preferably, the water circulation assembly is internally provided with ice blocks, a filter layer, slots and a water pump. A water pump is installed on one side of the cooling tank. The input end of the water pump is electrically connected to the output end of the control key. One end of the water pump is connected to one end of the spray pipe frame. The other end of the water pump passes through the cooling tank and extends into the interior of the water tank.

[0008] Preferably, ice is placed inside the water tank, and slots are provided on both sides of one end of the water tank. A filter layer is provided inside the slot, and the filter layer is inserted into the slot.

[0009] Preferably, a discharge rack is fixed on one side of the cooling box, the discharge rack is located outside the inlet / outlet, and the surface of the discharge rack is provided with air-cooling components.

[0010] Preferably, the air-cooled component includes a fan, a drain hole, and a water collection tank. The surface of the discharge rack is equipped with a fan, and the input end of the fan cooling structure is electrically connected to the output end of the control key.

[0011] Preferably, a water collection trough is provided at the bottom of the discharge rack, the water collection trough has an inclined structure, and a drain hole is provided on one side of the cooling box, the drain hole being connected to the water collection trough and the water tank respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the cooling structure of the chain annealing furnace not only saves the water resources required for the use of the cooling structure, but also saves the cooling time required for the use of the cooling structure;

[0013] Equipped with a water circulation mechanism, the gate can be opened before use, and then cooling water and ice can be placed into the water tank. During use, the heated workpiece is conveyed through the steel belt of the chain annealing furnace to the inlet and outlet and enters the cooling box. At this time, the control key can be operated to control the water pump. Under the action of the water pump, the cooling water in the water tank is guided to the spray pipe frame. Under the action of the spray pipe frame, the workpiece is sprayed and cooled. The sprayed water falls back into the water tank. The ice can further reduce the water temperature in the water tank. The filter layer can filter the water entering the water pump. At the same time, the filter layer can be pulled out and replaced or cleaned by the insertion and engagement of the filter layer with the slot. This realizes the circulating spray function of the cooling structure, thereby saving the water resources required for the use of the cooling structure.

[0014] With the air-cooling mechanism in place, the workpiece enters the discharge rack via a steel belt. At this time, residual water on the workpiece surface drips into the water collection tank and flows back into the water tank through the drain hole. Simultaneously, the control key can be operated to control the fan to work, blowing cold air onto the workpiece to accelerate its cooling. At the same time, the workpiece surface can also be dried, thus realizing the air-cooling function of the cooling structure and saving the cooling time required for its use.

[0022] Furthermore, such as Figure 2 and Figure 4As shown, the cooling tank 1 is equipped with a water circulation mechanism 2, which consists of a baffle 201 and a water circulation assembly 202. The baffle 201 is rotatably connected to the surface of the cooling tank 1. The water circulation assembly 202 is installed inside the cooling tank 1, and contains ice blocks 2021, a filter layer 2022, a slot 2023, and a water pump 2024. The water pump 2024 is installed on one side of the cooling tank 1. The water pump 2024 can be an SLG series model. The input end of pump 2024 is electrically connected to the output end of control key 101. One end of pump 2024 is connected to one end of spray pipe frame 102. The other end of pump 2024 passes through cooling box 1 and extends into the interior of water tank 103. Ice block 2021 is placed inside water tank 103. Slots 2023 are provided on both sides of one end of water tank 103. Filter layer 2022 is provided inside slot 2023. Filter layer 2022 and slot 2023 are interlocked.

[0023] Before use, the baffle 201 can be opened, and then cooling water and ice 2021 can be placed inside the water tank 103. During use, the heated workpiece is conveyed to the inlet / outlet 104 by the steel belt of the chain annealing furnace and enters the cooling box 1. At this time, the control key 101 can be operated to control the water pump 2024 to work. Under the action of the water pump 2024, the cooling water inside the water tank 103 is guided to the spray pipe rack 102. Under the action of 2, the workpiece is sprayed to cool it down. The sprayed water falls back into the water tank 103. Under the action of ice 2021, the water temperature inside the water tank 103 can be reduced. Under the action of filter layer 2022, the water entering the water pump 2024 can be filtered. At the same time, filter layer 2022 can be pulled out and replaced or cleaned by the insertion and cooperation of filter layer 2022 and slot 2023, so as to realize the circulating spray function of the cooling structure.

[0024] Furthermore, such as Figure 3 As shown, a cooling mechanism 3 is provided on one side of the cooling box 1. The interior of the cooling mechanism 3 includes a discharge rack 301 and a cooling component 302. The discharge rack 301 is fixed on one side of the cooling box 1. The discharge rack 301 is located outside the inlet / outlet port 104. The surface of the discharge rack 301 is provided with a cooling component 302. The interior of the cooling component 302 includes a fan 3021, a drain hole 3022 and a water collection tank 3023. The fan 3021 is installed on the surface of the discharge rack 301. The input end of the cooling structure of the fan 3021 is electrically connected to the output end of the control key 101. A water collection tank 3023 is provided at the bottom of the interior of the discharge rack 301. The structure of the water collection tank 3023 is inclined. A drain hole 3022 is provided on one side of the cooling box 1. The drain hole 3022 is connected to the water collection tank 3023 and the water tank 103 respectively.

[0025] In use, the workpiece enters the discharge rack 301 via the steel belt. At this time, the water stains remaining on the surface of the workpiece drip into the water collection tank 3023 and flow back into the water tank 103 through the drain hole 3022. At the same time, the control key 101 can be operated to control the fan 3021 to work. Under the action of the fan 3021, cold air is blown onto the workpiece to accelerate the cooling of the workpiece. At the same time, the surface of the workpiece can also be dried to realize the air cooling function of the cooling structure.

[0026] Working principle: Before use, the damper 201 can be opened, and then cooling water and ice 2021 can be placed into the water tank 103. During use, the heated workpiece is conveyed to the inlet / outlet 104 by the steel belt of the chain annealing furnace and enters the cooling box 1. At this time, the control key 101 can be operated to control the water pump 2024. Under the action of the water pump 2024, the cooling water in the water tank 103 is guided to the spray pipe rack 102. Under the action of the spray pipe rack 102, the cooling water is applied to the workpiece. The workpiece is cooled by spraying, and the sprayed water falls back into the water tank 103. Under the action of ice 2021, the water temperature inside the water tank 103 can be reduced. Under the action of filter layer 2022, the water entering the water pump 2024 can be filtered. At the same time, filter layer 2022 can be pulled out and replaced or cleaned by the insertion and cooperation of filter layer 2022 and slot 2023. This realizes the circulating spray function of the cooling structure, thereby saving the water resources required for the use of the cooling structure.

[0027] Subsequently, the workpiece enters the discharge rack 301 via the steel belt. At this time, the water stains remaining on the surface of the workpiece drip into the water collection tank 3023 and flow back into the water tank 103 through the drain hole 3022. At the same time, the control key 101 can be operated to control the fan 3021 to work. Under the action of the fan 3021, cold air is blown onto the workpiece to accelerate the cooling of the workpiece. At the same time, the surface of the workpiece can also be dried by air to realize the air cooling function of the cooling structure, thereby saving the cooling time required when using the cooling structure, and finally completing the use of the cooling structure.
