Description

Technical Field

[0001] This invention relates to a double-shell recovery condenser unit for rolling oil. Background Technology

[0002] A condenser is a component of a refrigeration system and a type of heat exchanger. It can convert gas or vapor into liquid and quickly transfer the heat in the condenser tubes to the air near the tubes. The working process of a condenser is an exothermic process, so the temperature of a condenser is always relatively high.

[0003] The heat in the condensate produced by traditional condensers is not effectively utilized again, resulting in a waste of resources and reducing the practicality of the condenser.

[0004] Copper and its alloys, including plates, strips, and foils, are widely used in various industries such as electronics, communications, instrumentation, and military. With the rapid development of the electronics and information industries, the demand for precision copper foil is increasing. Most large domestic copper plate and strip processing enterprises use imported rolling mills, and the rolling oils they use are all imported products specified by the rolling mill equipment suppliers. With the development of China's equipment manufacturing industry, domestically produced rolling mills have also reached a high level of technology, and domestically manufactured rolling oils have partially replaced imported oils. However, in high-quality precision machining, imported brands still dominate.

[0005] Rolling oil typically retains a certain amount of heat after use. Traditionally, the heat in rolling oil is not effectively utilized again, resulting in resource waste and reducing the practicality of the condenser. Furthermore, existing condensers have complex structures and are inconvenient to disassemble and assemble. Therefore, a double-shell recovery condenser unit for rolling oil has emerged. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a double-shell recovery condenser unit for rolling oil.

[0007] A double-shell recovery condenser unit for rolling oil includes a first chamber, a second chamber, and a third chamber. The interiors of the first, second, and third chambers are all hollow structures. The second chamber includes a lower chamber, the inner wall of which is connected to an inner chamber, and the outer wall of which is connected to an outer chamber. The lower surface of the first chamber has an insertion groove for inserting the outer chamber. The third chamber includes an upper chamber, the inner wall of which has an insertion body, and the outer wall of which is connected to a liquid storage pipe. The lower surface of the insertion body is embedded in the upper surface of the inner chamber. Both the upper chamber and the first chamber have liquid inlet pipes on their upper surfaces, and both the first and second chambers have liquid outlet pipes on their side walls. The lower surface of the liquid storage pipe has an oil outlet pipe.

[0008] As a further improvement, the lower surface of the second housing is provided with multiple support feet. The support feet prevent the second housing from directly contacting the ground, while facilitating the drainage of oil from the oil outlet pipe and protecting the entire housing.

[0009] As a further improvement, the inner box, outer box, first box, second box, third box, plug-in body, and plug-in groove are all circular in shape. The special structural design can meet the mutual plug-in connection of multiple boxes, so that the rolling oil temperature can be utilized to the maximum extent, reducing waste and having a certain environmental protection effect.

[0010] As a further improvement, the inner wall of the insertion slot, the inner side wall of the first box, the inner side wall of the second box, and the outer side wall of the second box are all connected with a heat insulation layer, which can better keep the heated liquid warm, reduce energy consumption, and achieve the maximum utilization effect.

[0011] As a further improvement, the outer wall of the first housing is embedded with multiple condenser tube groups arranged in a ring. Each condenser tube group is composed of multiple condenser tubes connected and spliced ​​together. The condenser tubes are U-shaped and the condenser tube groups are arranged in an equidistant array along the vertical direction. The U-shaped sealing end of the condenser tubes is located on the outer wall of the first housing.

[0012] As a further improvement, the outer side wall of the second box is provided with multiple semi-cylindrical locking posts, and the inner side wall of the first box is provided with multiple semi-cylindrical locking slots corresponding to the semi-cylindrical locking posts.

[0013] As a further improvement, inlet and outlet water valves are installed on the liquid outlet pipe, oil outlet pipe, and liquid inlet pipe to control the injection or discharge of liquid or rolling oil.

[0014] As a further improvement, the liquid storage tube is in the shape of an arc. Beneficial effects

[0015] This device adopts a multi-layer design, which can maximize the temperature utilization rate of the rolling oil and, together with the insulation layer, greatly extend the heat preservation of the liquid. By using multiple layers of rolling oil for heating, the heating efficiency of the liquid is improved, which solves the problem that the heat in the traditional rolling oil is not effectively utilized again, reduces resource waste, improves the practicality of the condenser, and has environmental protection effects.

[0016] This device has a simple structure and is easy to install. It uses the gravity of each box to connect the equipment, making disassembly and assembly simple. It is easy to use and maintain. All components can be disassembled and replaced, reducing maintenance costs and solving the problem of complex condenser structure and inconvenient disassembly and assembly in existing technologies.
