Description

Technical Field

[0001] The utility model relates to the technical field of casting operations, in particular to a movable fume hood for a casting pool. Background Art

[0002] In industry, casting devices are often needed. Take the casting of ferrosilicon or high-purity ferrosilicon as an example. When casting molten iron in the molten iron casting pool, a large amount of high-temperature flue gas will be generated. These high-temperature flue gases need to be purified to meet environmental protection standards before they can be discharged. Therefore, a smoke hood is set directly above the molten iron casting pool to absorb the high-temperature flue gas and then discharge it. However, in the actual production process, there are many casting pools. If the same number of smoke hoods are set accordingly, it will cause unnecessary waste of resources, because not every casting pool needs to be cast, and usually multiple casting pools will not be casting at the same time, so there is no need to set too many smoke hoods. Utility Model Content

[0003] The utility model aims to provide a mobile fume hood for a casting pool, so as to solve the problem that too many fume hoods will cause waste of resources.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A mobile smoke hood for a casting pool comprises an air collecting hood, a smoke duct is connected to the top of the air collecting hood, a condenser is connected to the outlet end of the smoke duct, a telescopic hose is connected to the outlet end of the condenser, a fixed guide rail is provided above the condenser, the top of the condenser is slidably connected to the bottom surface of the fixed guide rail, and a driving mechanism is provided on the side of the condenser.

[0006] A further technical solution is that a movable groove is provided on the bottom surface of the fixed guide rail, both ends of the movable groove are closed ends, the opening size of the movable groove is smaller than the size of the groove bottom, and a connecting block is provided in the movable groove, the cross-sectional shape and size of the connecting block are consistent with the cross-sectional shape and size of the movable groove, and the connecting block is fixedly connected to the top surface of the condenser.

[0007] A further technical solution is that the driving mechanism includes a driving motor, a screw rod is fixedly connected to the output shaft of the driving motor, the axis of the screw rod is parallel to the axis of the movable groove, a connecting plate is threadedly connected to the screw rod, and the end of the connecting plate away from the screw rod is fixedly connected to the condenser.

[0008] A further technical solution is to provide a rock wool layer on the inner walls of the gas collecting hood and the smoke duct.

[0009] A further technical solution is that the telescopic hose is a bellows.

[0010] A further technical solution is that a plurality of movable plates are fixedly connected to the outer wall of the telescopic hose, a guide rod is provided on one side of the telescopic hose, the axis of the guide rod is parallel to the axis of the movable groove, and the plurality of movable plates are slidably connected to the guide rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model can control the position of the smoke hood by means of the driving mechanism provided, so that the smoke hood can be accurately moved to above the casting pool where smoke is generated. When a single smoke hood can process and discharge the smoke in the casting workshop, there is no need to provide more smoke hoods, which can effectively reduce the waste of resources. The movable plate and the guide rod arranged on the outer wall of the telescopic hose can neatly store and shorten the telescopic hose, thereby preventing the telescopic hose from partially falling and being damaged by other components.
