Description

Technical Field

[0001] The utility model mainly relates to the technical field of metal heat treatment process, in particular to a filtering device for a water quenching tank. Background Art

[0002] Water quenching is a commonly used cooling method in heat treatment. Its principle is to quickly remove the heat on the surface of the material to achieve rapid cooling. Water quenching can be divided into two methods: beam quenching and immersion quenching. The former is to impact the surface of the material with a high-pressure water beam, while the latter is to cool the material by immersing it in water. However, during the water quenching process, the water-quenched metal will produce water quenching slag that falls into the water.

[0003] Patent No. CN218811841U discloses a water quenching device for slag. The device is achieved through the cooperation of a filter basket, a guide groove and a guide slide in a water pool. When the filter basket is placed into the main frame of the water pool, the guide slides on both sides of the filter basket first contact the upper part of the guide groove, and the guide groove guides the guide slide, and finally brings out the water-quenched slag, solving the problem that the current water quenching method is that the mine car directly pours the slag into the cooling pool, and then the waste slag is taken out from the cooling pool by a forklift or a grab car, but due to the brittle nature of the waste slag, the process of cleaning the waste slag is more troublesome.

[0004] However, the mesh size of the filter is limited. Larger meshes may not be able to completely filter out smaller water-quenched slag, resulting in water-quenched slag still existing in the water, while smaller meshes may become clogged, making subsequent cleaning difficult. Therefore, a water quenching tank filtering device is needed to solve the above problems. Utility Model Content

[0005] The technical solution of the utility model aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. It mainly provides a filtering device for a water quenching tank to solve the technical problems raised in the above background technology.

[0006] The utility model adopts the following technical solution to solve the above technical problems: a filtering device for a water quenching tank, comprising a water quenching tank, wherein the inner ring of the water quenching tank is slidably connected to the outer ring of the slag taking tank, two water guide ports are provided on both sides of the water quenching tank, the water guide ports perpendicular to each other are connected to a water connecting frame tank, the water connecting frame tank is connected and fixed to the water quenching tank, a traction device is arranged at the bottom of the water quenching tank, and the traction device is connected and fixed to the tops of both sides of the slag taking tank.

[0007] Preferably, a filter screen is arranged in the water inlet at the upper end of the water quenching tank, and the water height in the water quenching tank is not higher than the water inlet.

[0008] Preferably, the traction device includes a protective shell, a driving motor is installed in the protective shell, the output end of the driving motor is transmission-connected to three equidistantly arranged circular wheels, a traction rope is respectively arranged in the gap between the circular wheels, one end of the traction rope is connected and fixed to the circular hole opened at the output end of the driving motor through a fixing device, and the other end of the traction rope passes through the protective shell and is connected and fixed to the slag trough.

[0009] Preferably, the gap between the round wheels is the same as the caliber of the traction rope.

[0010] Preferably, the traction rope contacts the outer rings of guide rollers arranged at the top and bottom of the water quenching tank.

[0011] Preferably, the fixing device includes a fixing bolt, which is located at a fixing recessed hole opened at the output end of the driving motor, a threaded hole is opened at the lower end of the fixing recessed hole, the threaded hole is threadedly connected to the fixing bolt, the fixing bolt passes through the threaded hole and is threadedly connected to the arc plate, and the arc plate is in contact with the traction rope.

[0012] Preferably, a thread groove is provided on the arc-shaped plate on one side close to the traction rope.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows: the circular wheel is driven to rotate by the driving motor, and then the output end of the driving motor drives one end of the traction rope, and the other end of the traction rope pulls the slag trough up, thereby facilitating the staff to remove the water-quenched slag and impurities. At the same time, the staff can clean the filter by themselves to ensure that the water quenching tank can be used uninterruptedly.

[0014] The rising of the slag taking trough can cause the water and the water-quenched slag to rise at the same time, and then the water enters the water frame trough through the water guide port and finally flows back to the water quenching trough, thereby avoiding water loss and achieving the effect of recycling. In addition, the slag taking trough is not equipped with a filter screen, so that the water-quenched slag can be completely taken out.
