Description

Technical Field

[0001] The present application relates to the technical field of quenching oil, and in particular to a quenching oil circulation device for a quenching oil tank. Background Art

[0002] Quenching oil is a cooling medium used in the process of metal heat treatment. Its main function is to quickly reduce the temperature of the workpiece during the quenching process, so as to achieve the required hardness and microstructure. It has a very fast cooling rate, which is faster than that of rapid quenching oil. It is usually used for metal parts with larger cross-sections and deeper hardened layers. The quenching oil can be cooled and filtered through a circulation device during use, and then put into use again. It can reduce the consumption of new oil and the frequency of replacement, reduce the generation of waste oil, and thus reduce production costs. At the same time, a reasonable circulation system design can also reduce energy consumption and improve energy utilization efficiency. The current quenching oil circulation device simply cools the quenching oil, but cannot know the specific cooling situation, and the filter screen is not convenient to disassemble, which may cause blockage, thereby affecting the subsequent circulation efficiency.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, they are further elaborated below in conjunction with specific implementation methods.

[0023] A quenching oil circulation device for a quenching oil tank, see Figures 1 to 5, including a base 1, a delivery pipe 4, a return pipe 5, a filter box 7 and a thermometer 15, the top two sides of the base 1 are fixedly connected with the oil tank 2 and the cooling box 3, the two ends of the delivery pipe 4 are connected with the oil tank 2 and the cooling box 3 respectively, one end of the return pipe 5 is connected with the lower side wall of the cooling box 3, and the other end of the return pipe 5 is located just above the oil tank 2. Two filter tanks 9 are provided on the inside of the filter box 7, and a filter insert 10 is movably inserted into the inside of the filter tank 9. When replacing the filter insert 10, it can be directly pulled out, and the branch pipe 8 is provided to ensure that when one of the filter inserts 10 is replaced, the other filter insert 10 can work normally, thereby ensuring the normal reflux of the quenching oil; the outer wall of the cooling box 3 is fixedly connected with a plug 14, and the outer side of the plug 14 A number of plug-in channels 141 are evenly and vertically opened on the surface, and a thermometer 15 is movably inserted into the inner side of the plug-in channel 141. The thermometer 15 is arranged in multiple layers, so that the temperature of the quenching oil at different heights can be monitored during the descent of the quenching oil, thereby improving the monitoring efficiency. The plug-in channel 141 is connected to the closed channel 17, and the closed channel 17 is opened on the side wall of the insertion strip 14 outside the cooling box 3, and a closing plate 18 is movably inserted into the inner side of the closed channel 17. The closing plate 18 is inserted into the closed channel 17, thereby blocking the plug-in channel 141, and when the quenching oil is cooled and the thermometer 15 is pulled out, the scraper 16 can scrape off the quenching oil on the surface of the thermometer 15 to avoid bringing it out of the cooling box 3, thereby preventing the quenching oil from leaking.

[0024] Specifically, such as Figure 5 As shown, a scraper is fixedly connected to the opening of the plug-in channel 141 inside the cooling box 3. The scraper fits the surface of the thermometer 15. The scraper can scrape off the quenching oil on the surface of the thermometer 15 when the thermometer 15 is pulled out to avoid it being pulled out of the cooling box 3.

[0025] It is worth noting that if Figure 2 As shown, a number of baffles 13 are staggered and fixedly connected to the inner side of the cooling box 3, and the closed channel 17 is located between the upper and lower baffles 13. The baffles 13 can increase the flow path of the quenching oil, so that there is more time for cooling, thereby improving the cooling efficiency.

[0026] It is worth noting that if Figure 4 As shown, both sides of the filter tank 9 are fixedly connected and connected with a branch pipe 8, the return pipe 5 passes through the outer wall of the filter box 7 and is connected with the branch pipe 8, and the surface of the branch pipe 8 is movably connected with a filter valve 801. The filter valve 801 can close the current branch pipe 8 channel to ensure that the quenching oil will not leak when the filter plug-in plate 10 of the current channel is replaced.

[0027] It is worth noting that if Figure 2As shown, a heat exchanger 11 is fixedly connected to the outer wall of the cooling box 3, and the heat exchanger 11 is connected to a water cooling pipe 12. The water cooling pipe 12 is located on the inner side of the cooling box 3 and passes through the baffle 13. The water cooling pipe 12 cools the quenching oil passing through it.

[0028] It is worth noting that if Figure 5 As shown, the outer wall of the closing plate 18 is threadedly connected with a fixing bolt 181, and a corresponding bolt hole is opened on the surface of the inserting strip 14 at the horizontal position of the fixing bolt 181. The fixing bolt 181 ensures the stability of the closing plate 18 and prevents it from slipping out of the closed channel 17.

[0029] It should be noted that the maximum measurement value of the thermometer 15 used in this solution exceeds the upper limit of the maximum temperature of the quenching oil, thereby ensuring that it will not be damaged.

[0030] During actual use, the quenching oil in the oil tank 2 flows along the delivery pipe 4 into the cooling box 3, and after being cooled by the water-cooling pipe 12, it is pumped back to the oil tank 2 by the oil pump 6, so as to be recycled. In this process, the temperature of the oil tank 2 can be monitored by the insertion strip 14, the plug-in channel 141, the thermometer 15 and the closing plate 18. The thermometer 15 is inserted into the plug-in channel 141, and the current temperature can be checked when the quenching oil passes through, so as to know the specific cooling situation. The thermometer 15 can also be directly pulled out, which is convenient for maintenance and care. The thermometer 15 is arranged in multiple layers, so that the temperature of the quenching oil at different heights can be monitored during the descent of the quenching oil, thereby improving the monitoring efficiency. The scraper 16, the closed channel 17 and the closing plate 18 can prevent the quenching oil from leaking. When the front plug-in channel 141 is not in use, the closing plate 18 is inserted into the closing channel 17 to block the plug-in channel 141. Moreover, when the quenching oil is cooled and the thermometer 15 is pulled out, the scraper 16 can scrape off the quenching oil on the surface of the thermometer 15 to avoid it being brought out of the cooling box 3, thereby avoiding leakage of quenching oil to cause pollution and waste. At the same time, the filter box 7, branch pipe 8, filter tank 9 and filter insert 10 can facilitate the removal of the filter net. The filter insert 10 is equipped with a filter net on the inside, which can filter the quenching oil when inserted into the filter tank 9. It can be directly pulled out when replaced. The branch pipe 8 can ensure that when one of the filter inserts 10 is replaced, the other filter insert 10 can work normally, thereby ensuring the normal reflux of the quenching oil and improving the filtering efficiency and practicality of the device.
