Description
Technical Field
[0001] The utility model relates to the technical field of metal processing and manufacturing, in particular to a cooling device for a sucker rod after quenching. Background Art
[0002] Quenching is a metal heat treatment process that heats the metal workpiece to an appropriate temperature and maintains it for a period of time, and then immerses it in a cooling medium for rapid cooling. The sucker rod is the main force-bearing component in the oil production process of the oil well, and the sucker rod needs to be subjected to medium-frequency quenching during the production process to allow the sucker rod to undergo heat treatment.
[0003] Some equipment on the market generally sprays the cooling medium onto the sucker rod through the water spray hole. The cooling medium in the water spray barrel can completely submerge the rod body, making it evenly cooled and not prone to thermal stress, etc., to prevent the rod body from deformation or insufficient local hardness. The cooling medium flow and flow rate are adjustable and can be applied to products of different specifications and requirements.
[0004] However, during the actual use of the above equipment, when the sucker rod is cooled by the cooling device, its outer surface may cool quickly and produce some debris, which may block the nozzle when being washed down by the cooling medium. In view of this, we propose a cooling device for the sucker rod after quenching. Summary of the invention

[0012] Compared with the prior art, the utility model provides a cooling device for sucker rods after quenching, which has the following beneficial effects:
[0013] 1. In order to prevent the medium nozzle from being blocked by debris and thus slowing down the cooling speed, the cooling medium enters the water spray barrel through the delivery pipe, and the inner wall of the water spray barrel is provided with a nozzle to spray the outer surface of the sucker rod body. During the spraying process of the cooling medium, the filter element will filter the cooling medium and then contact the sucker rod body, which can effectively filter the debris in the cooling medium and prevent the debris from contacting the outer surface of the sucker rod body. After cooling, the outer surface of the sucker rod body will have debris, which will be washed down to the inner wall of the filter element by the cooling medium, effectively preventing the debris on the outer surface of the sucker rod body from falling and blocking the nozzle.
[0014] 2. The cooling device for the sucker rod after quenching is used to prevent the filter device from being blocked by debris during quenching. A large amount of steam will appear on the sucker rod body when it is cooled. The steam moves upward and contacts the baffle. The baffle is set in an inverted U shape, which will cause the filter element to move upward for a certain distance. The pressing plate is pushed by the elastic force of the spring to reset the fixed block, which will cause the filter element to shake. The filter element is set in an hourglass shape, so that when the filter element shakes, the debris inside the filter element will be shaken out of the filter element.
