Description

Technical Field

[0001] The utility model relates to the technical field of casting equipment, in particular to a dust removal device of a sand falling machine. Background Art

[0002] The sand dropping of castings is one of the important processes in the sand casting production process. Sand dropping is to break the casting mold after the casting mold is poured and cooled to a certain temperature, so that the casting mold is separated from the sand box, and the casting is separated from the molding sand. In recent years, although the sand dropping equipment has developed to a certain extent, its mechanization degree lags far behind the development of molding mechanization. Therefore, how to further improve the mechanization and automation degree of sand dropping cleaning is a very urgent task. At present, the sand dropping method commonly used in casting production is the vibration method (impact method), that is, the sand dropping is achieved by the collision between the casting mold and the sand dropping machine. The sand dropping machine is divided into mechanical vibration type and electromagnetic vibration type according to the method of generating vibration. In the process of vibration sand dropping, a large amount of high-temperature and high-concentration dust will be generated, which will pollute the environment and also harm the health of on-site workers.

[0003] Application number: CN202021406852.8 discloses a dust removal device used for a vibrating sand-falling machine. It is characterized in that: a dustproof shell is placed outside the vibrating sand-falling machine, sound insulation cotton is fixed inside the dustproof shell, a strong magnet is fixedly connected to the end face of the dustproof shell, a feeding door is magnetically attracted to the strong magnet, the top of the feeding door is hinged to the dustproof shell through a rotating shaft, a feeding door handle is fixedly connected to the surface of the feeding door, a dust bag fixing ring is inserted in the ash discharge pipe, a dust bag frame is fixed at the lower end of the dust bag fixing ring, a clamping column is inserted in the buckle, and a spring is sleeved on the clamping column. By adding a dustproof shell, the dust generated by the vibration will not be emitted into the air to pollute the air, and under the action of the centrifugal fan, the dust will enter the ash collection bag along the ash discharge pipe, so that the dust will be collected and will not spread into the air or be inhaled into the body by the operator.

[0004] However, the above device does not take into account the impact of high temperature sand dust on the device when used. High temperature sand dust can easily cause safety hazards and is not conducive to the stable operation of subsequent sand processing links. Therefore, it is necessary to propose a dust removal device for a sand falling machine. Utility Model Content
