Description

Technical Field

[0001] The utility model belongs to the technical field of oil coolers, in particular to an explosion-proof oil cooler. Background Art

[0002] The explosion-proof oil cooler is a specially designed cooling equipment. Its main features are its explosion-proof performance and efficient heat dissipation capacity. It is widely used in industrial fields with explosion hazards such as liquid rocket fuel, liquid gas, and other equipment that requires long-term high-speed operation and oil temperature is easy to rise. The explosion-proof oil cooler has stable performance, efficient heat dissipation efficiency and safe and reliable explosion-proof design. It can timely and effectively control the oil temperature within an appropriate range, ensure the normal operation of the equipment, and improve production efficiency.

[0003] During the use of the oil cooler, the condenser plays a vital cooling role to ensure that the oil can circulate within the appropriate temperature range. However, when the oil pipeline in the condenser is installed by welding or using fastening screws, it is difficult for maintenance personnel to thoroughly clean the inside of the pipeline. This installation method makes it difficult to remove oil stains and impurities in the pipeline. Long-term accumulation will cause oil stains to accumulate and clog the pipeline, and even form a hard oil layer. The accumulation of oil stains will not only reduce the heat dissipation efficiency of the condenser, making it impossible for the oil to be effectively cooled, thereby affecting the operation effect of the entire oil cooling system. At the same time, the blocked pipeline will also hinder the normal circulation of the oil, resulting in problems such as insufficient flow and unstable pressure, further increasing the risk of equipment failure. More seriously, the accumulation of oil stains may also pose a threat to the safe operation of the equipment. The formation of an oil stain layer will aggravate the corrosion and wear of the pipeline and shorten the service life of the equipment. In addition, under high temperature and high pressure environments, oil stains may also cause safety accidents such as fires, causing huge losses to personnel and equipment.

[0004] For this purpose, an explosion-proof oil cooler is proposed. Utility Model Content

At the same time, the cooling pipeline 162 circulates the cooling medium and exchanges heat with the oil through the conduction of the heat sink 161, quickly taking away the heat in the oil, thereby achieving effective cooling of the oil. It can not only ensure the stability and efficiency of the oil circulation, but also achieve the ideal cooling effect of the oil in a short time through precise control of the cooling medium.

[0033] In this embodiment, after the bottom of the oil pipeline 165 is clamped in the inner cavity of the connecting pipe 163, the return spring 23 recovers its deformation and extends inward when the force is lost, and drives the guide rod 22 to move inward, the guide rod 22 drives the movable plate 24 to move inward, and the movable plate 24 drives the limit block 25 to move inward, so that the inner side of the limit block 25 is clamped in the limit groove 1654, and the oil pipeline 165 and the connecting pipe 163 are limited, simplifying the installation process and improving the connection effect. At the same time, by pulling the pull plate 28 outward, the pull plate 28 drives the guide rod 22 to move outward, so that the limit block 25 is no longer clamped in the limit groove 1654, which is convenient for connecting the connecting pipe 163 and the oil pipeline 165. It can be quickly separated to facilitate the disassembly of the oil pipeline 165 for cleaning or maintenance. By setting the buckle 164, the stability of the oil pipeline 165 during use can be further improved. By setting the slide groove 26 and the slider 27, the stability of the movable plate 24 during horizontal movement can be effectively improved to avoid displacement of the guide rod 22 and the movable plate 24 during horizontal movement. By setting the clamping block 29 and the clamping groove 210, the pull plate 28 can be fixed, thereby improving the stability of the guide rod 22 during use, thereby improving the clamping effect between the limit block 25 and the limit groove 1654, and by setting the sealing ring 1633, the sealing effect between the oil pipeline 165 and the connecting pipe 163 can be improved.

[0034] When the utility model is working: the pneumatic diaphragm pump 15 sucks the oil in the inner cavity of the oil storage tank 14 and transports it to the inner cavity of the oil pipeline 165 through the connecting pipe 163, and at the same time, the cooling pipeline 162 circulates the cooling medium and exchanges heat with the oil through the conduction of the heat sink 161, quickly taking away the heat in the oil, thereby achieving effective cooling of the oil, which can not only ensure the stability and efficiency of the oil circulation, but also achieve the ideal cooling effect of the oil in a short time through precise cooling medium control, and at the same time, improve the reliability and service life of the equipment, reduce the failure rate and maintenance cost, and the oil after cooling is transmitted to the oil outlet pipe 110 through the first regulating valve 17, the oil circuit distribution valve 18 and the oil filter 19, and the oil outlet pipe 110 transports the oil to the working oil tank, so that the oil temperature of the working machine is maintained;

[0035] When the oil body pipeline 165 needs to be disassembled for cleaning or maintenance, the pull plate 28 is first pulled outward, and the pull plate 28 drives the guide rod 22 to move outward. The guide rod 22 drives the limit block 25 to move outward through the movable plate 24, so that the limit block 25 is no longer stuck in the limit groove 1654, which facilitates the quick separation between the connecting pipe 163 and the oil body pipeline 165, effectively saving manpower;

[0036] When the oil pipeline 165 needs to be installed, first pull the pull plate 28 outward, the pull plate 28 drives the guide rod 22 to move outward, and the guide rod 22 drives the return spring 23 to deform and squeeze outward, then the oil pipeline 165 is clamped into the buckle 164, and the oil pipeline 165 is moved downward, so that the bottoms on both sides of the oil pipeline 165 are respectively clamped into the inner cavities of the connecting pipes 163 on both sides, and the pull plate 28 is released. At this time, the return spring 23 loses its force. The influence of the recovery deformation extends inward and drives the guide rod 22 to move inward, the guide rod 22 drives the movable plate 24 to move inward, the movable plate 24 drives the limit block 25 to move inward, so that the inner side of the limit block 25 is clamped in the limit groove 1654, and the clamping block 29 is clamped in the clamping groove 210 at this time, limiting the position between the oil body pipeline 165 and the connecting pipe 163, simplifying the installation process, and improving the connection effect between the connecting pipe 163 and the oil body pipeline 165.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
