Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Firstly, in order to facilitate understanding of the water circulation device for spray quenching provided in the embodiments of the present application, an application scenario of the water circulation device for spray quenching in the embodiments of the present application is described, in which a medium is uniformly and stably cooled on a surface of an object by a rotatable water spray ring, and the medium is recycled.

The following describes a water circulation device for spray quenching provided in the embodiments of the present application with reference to the accompanying drawings.

Referring to fig. 1-2 together, fig. 1 is a schematic structural diagram of a water circulation device for spray quenching according to an embodiment of the present invention; the water circulating device for spray quenching in the embodiment of the application comprises: a quenching cylinder 1; this quenching section of thick bamboo 1 is as the quenching household utensils in this application embodiment for the top open end that gets into quenching case through hoist and mount subassembly with the object that waits to quench is cooled down.

This quenching case adopts and sprays the quenching, and current spraying quenching sprays cooling medium and is mostly water column to cause to have the injection contained angle between a plurality of nozzles, make the cooling of object whole body inhomogeneous. Therefore, in the embodiment, the rotating water spraying ring 3 is adopted to uniformly spray the cooling medium under the rotating driving force in the rotating process, so as to cool the whole body of the surface of the object.

Specifically, the top of the quenching cylinder 1 is butted with a water storage sleeve 2, the top of the water storage sleeve 2 is rotatably connected with a water spray ring 3 communicated with the water storage sleeve 2, and the bottom of the water spray ring 3 is provided with an annular hole communicated with the water storage sleeve 2. The inner wall circumference of water spray ring 3 is provided with a plurality of sprinkler bead 7, and a plurality of sprinkler bead 7 are upper and lower layering dislocation set, thereby rotate the in-process at water spray ring 3 and realize evenly spraying the medium. As shown in fig. 2, the water spray ring 3 is rotatably connected to the water storage jacket 2 via a bearing 14, so that the water spray ring 3 can be rotated stably and reliably.

When the water spraying ring 3 is rotated, the present embodiment further includes a driving mechanism; the drive mechanism includes: the gear ring 4 and the driving motor 5 are sleeved on the outer wall of the water spraying ring 3, and a gear 6 meshed with the gear ring 4 is arranged on an output shaft of the driving motor 5. The gear 6 is engaged with the gear ring 4 to rotate by starting the driving motor 5, so that after a medium with set pressure is injected into the water storage sleeve 2, the medium flows into the water spraying ring 3 and is sprayed out by the plurality of water spraying heads 7, and in the rotating process of the water spraying ring 3, the cooling medium sprayed out by the plurality of water spraying heads 7 is uniform and stable and is fully contacted with the surface of an object for cooling.

With continued reference to fig. 2, in addition, the temperature of the medium after contacting the object is high, and the used medium contains a part of impurities, and the recycling of the medium again causes an undesirable cooling effect; therefore, in the embodiment, the quenching device further comprises a filter screen partition plate 12 arranged inside the quenching cylinder 1, a drainage cavity 13 is arranged at the bottom of the filter screen partition plate 12, the drainage cavity 13 is connected with a condenser 9, a water pump 10 is arranged inside the condenser 9, and the water pump 10 is connected with the water storage jacket 2 through a return pipe 11. In the structure, the impurities in the used medium are filtered by the filter screen partition plate 12, the medium is drained to the condenser 9 through the drainage cavity 13 for cooling, and then the medium is pumped into the water storage jacket 2 through the water pump 10, so that the pressure in the water storage jacket 2 is increased, the high-pressure medium enters the water spraying ring 3 and is sprayed out by the plurality of water spraying heads 12, and the object is uniformly cooled.

In addition, during the cooling of the object, a large amount of water vapor is generated, so that the temperature around the object is high, and the quenching process of the object is not easily observed. Therefore, the present embodiment further includes a heat dissipation fan 8, and the heat dissipation fan 8 is located on the top side of the water spraying ring 3. The heat radiation fan 8 absorbs and discharges a large amount of generated water vapor, and reduces the ambient temperature of the object, so that the whole quenching process is clearly shown.

The utility model discloses in, through the rotation of water spray ring 3, make a plurality of sprinkler bead 7 spray even, stable in the medium of a quenching section of thick bamboo 1, do not have the dead angle cooling to the object surface to the medium after heaing up filters the back condensation cooling, makes low temperature medium recycle, strengthens quenching effect, improves the availability factor of the energy.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
