Description

Technical Field

[0001] This utility model relates to the field of water circulation cooling technology for quenching furnaces, specifically a circulating cooler for quenching furnaces. Background Technology

[0002] Quenching involves placing the workpiece in a furnace, heating it to a quenching temperature above the critical point, holding it for a period of time, and then quickly removing the workpiece from the furnace and immersing it in a quenching solution (oil or water) for quenching. A circulating cooler for the quenching furnace can extract, cool, and recycle the water used for quenching. For example, Chinese utility model patent CN 218755890U discloses a circulating cooling device for a quenching furnace. This device uses a water pump to guide water from the processing tank through an outlet pipe into a filter box. The water is then filtered by filter plates within the filter box. After filtration, the water is cooled and reintroduced into the processing tank through a return pipe and cooling components installed on the return pipe, thus allowing the quenching water to be recycled.

[0003] However, the circulating cooling device for the quenching furnace has the following problems when it is reused: it uses a water pump to introduce water from the processing tank into the filter box through the outlet pipe, and then filters the water through the filter plate in the filter box. The waste residue in the water can easily cause problems such as impeller jamming and wear of seals inside the water pump. Utility Model Content

The filter cylinder is detachably extended into the inner cavity of the branch pipe from the lower end. The upper end of the filter cylinder has an opening, and multiple filter holes are formed on the outer wall of the filter cylinder, so that the water input through the input pipe flows through the filter cylinder for filtration and is then discharged.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1 A circulating cooler for a quenching furnace may include a circulating input component 10, a water pump 20, a circulating output component 30, and a support 40. The water pump 20 is installed and fixed inside the support 40, and the circulating output component 30 is supported and fixed on the top of the support 40. The circulating input component 10 and the circulating output component 30 are respectively connected to the input and output ends of the water pump 20, and both the circulating input component 10 and the circulating output component 30 are also connected to the water tank used for quenching. This allows the water pump 20 to draw water through the circulating input component 10 and input it into the circulating output component 30. The water is cooled in the circulating output component 30 and then output to the water tank used for quenching.

[0022] See Figure 2The circulating input assembly 10 includes an input pipe 11, a branch pipe 12, a positioning protrusion ring 131, and a filter cylinder 14. The input pipe 11 is a straight pipe, with its end near the water pump 20 connected to the input end of the water pump 20, and its end near the water tank used for quenching connected to the water tank. The branch pipe 12 is an inclined pipe, connected to the lower end of the input pipe 11. The positioning protrusion ring 131 is fixedly connected to the inner cavity of the input pipe 11, facing the inner cavity of the branch pipe 12, and is coaxially distributed with the branch pipe 12. The filter cylinder 14 is detachably inserted into the inner cavity of the branch pipe 12 from its lower end. A fixing part 141 is formed at the lower end of the filter cylinder 14, and the fixing part 141 and the branch pipe 12 can be fixed by a threaded connection or by fasteners such as bolts, allowing the filter cylinder 14 to be disassembled for cleaning. The filter cylinder 14 has an opening at its upper end. A positioning protrusion 131 is formed on the side of the diversion pipe 12. The upper end of the filter cylinder 14 is inserted into the positioning protrusion 131, and the upper end face of the filter cylinder 14 is in contact with the positioning protrusion 131. This allows water from the tank to flow into the input pipe 11 and then into the filter cylinder 14 along the diversion pipe 12. The filter cylinder 14 filters impurities, trapping them in its inner cavity, while the water flows out through the filter holes. The outer diameter of the filter cylinder 14 is smaller than the inner diameter of the diversion pipe 12, creating a channel for water flow between the filter cylinder 14 and the diversion pipe 12. The filtered water can then flow through this channel to the rear end of the input pipe 11 and be pumped by the water pump 20 to the circulation output assembly 30. In addition, the opening diameter at the upper end of the filter cylinder 14 is matched with the inner diameter of the positioning protrusion ring 131 so that the water entering the input pipe 11 can only flow out after being filtered by the filter cylinder 14, thus preventing the water from flowing directly to the rear end of the input pipe 11 through the diversion pipe 12.

[0023] See Figure 3The circulating output assembly 30 includes a cooling chamber 31, a top cover 32, a thermal pad 33, heat dissipation fins 34, a mounting support 35, and a radiator 36. A connecting pipe 311 is formed at the bottom of the cooling chamber 31, connecting to the output end of the water pump 20. An output pipe 312 for discharging water is also connected to the side of the connecting pipe 311, and the output pipe 312 is connected to a water tank. The top cover 32 is detachably installed and fixed to the top of the cooling chamber 31. A monitoring chamber 321 is formed at the bottom of the top cover 32, protruding downwards and extending into the interior of the cooling chamber 31. A temperature sensor is installed in the monitoring chamber 321, and the probe of the temperature sensor extends into the interior of the cooling chamber 31, allowing it to measure the water temperature inside the cooling chamber 31 for monitoring. A thermal pad 33 is disposed between the heat dissipation fins 34 and the upper cover 32. The heat dissipation fins 34 are fixed to the upper cover 32 by fasteners. Both the heat dissipation fins 34 and the upper cover 32 can be made of metal materials with high thermal conductivity. The thermal pad 33 can be made of silicone sheet and fills the gap between the heat dissipation fins 34 and the upper cover 32, allowing the water in the cooling chamber 31 to conduct heat through the upper cover 32, the thermal pad 33, and the heat dissipation fins 34. A mounting support 35 is installed on top of the heat dissipation fins 34 and is used to support the installation of the radiator 36. The radiator 36 can be a cooling fan or a blower, which can accelerate the airflow at the heat dissipation fins 34 for heat dissipation when in use.

[0024] The system of the present invention may further include a control system for controlling the operation of the aforementioned water pump and radiator to perform automatic water circulation and cooling. It should be understood that the control system is not particularly limited and can be implemented using existing control techniques, which will not be elaborated upon here.

[0025] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
