Environment-friendly knock-out barrel

Abstract

The invention discloses an environment-friendly knock-out barrel. The environment-friendly knock-out barrel comprises a base, support bases are arranged in the middle of the upper end of the base at intervals, a roller is arranged over the support bases, the inner wall of the roller is provided with an inner thread, a driving mechanism used for driving the roller to rotate is arranged at the upperend of the base, and sand outlet holes are formed in the portion, on one side of the discharging end, of the side wall of the roller; the support bases are arranged at the upper end of the base, an outer pipe with the two open ends is arranged at the upper ends of the support bases, the roller is arranged in the outer pipe, the outer wall of the roller is provided with an outer thread, and a sanddischarging hole is formed in the portion, on the far side of the discharging end, of the bottom wall of the outer pipe; and brackets are arranged on the portions, on the two sides of the open ends of the outer pipe, of the upper end of the base, a ventilation pipe is arranged between the brackets on the two sides, sprayer heads are arranged on the portions, in one section of the roller, of the side wall of the ventilation pipe, a dust removing device is arranged at the upper end of the outer pipe, and a feeding device is arranged on the portion, on one side of the feeding end, of the base. According to the environment-friendly knock-out barrel, feeding is easy; and meanwhile, the dust removing device is arranged in the middle section of the roller, and then it is guaranteed that dust cannot overflow.

Description

technical field [0001] The invention relates to the field of casting equipment, in particular to an environment-friendly drum shakeout machine. Background technique [0002] Casting is a commonly used metal thermal processing process, that is, the metal is smelted into a liquid and then poured into a mold made of molding sand. After the liquid metal is cooled and solidified in the cavity in the mold, in order to obtain the casting, the molding sand needs to be removed from the casting. The surface is separated. The existing method is to use the vibration and impact generated by the shakeout machine to complete the shakeout. Compared with the vibrating shakeout machine, the drum shakeout machine has the advantages of easy noise control and good working conditions, so the application More and more widely, the existing drum shakeout machine is equipped with a dust removal fan at the inlet and outlet of the drum to collect the dust overflowing from the outlet of the drum, but be...

The existing method is to use the vibration and impact generated by the shakeout machine to complete the shakeout. Compared with the vibrating shakeout machine, the drum shakeout machine has the advantages of easy noise control and good working conditions, so the application More and more widely, the existing drum shakeout machine is equipped with a dust removal fan at the inlet and outlet of the drum to collect the dust overflowing from the outlet of the drum, but because the amount of dust is too large, the dust will still diffuse into the air, which is not conducive to environmental protection; at the same time When the mold is heavy and ready to enter the drum shakeout machine, it still has a certain temperature, so it is difficult to put the mold into the drum shakeout machine
