Description

Technical Field

[0001] The utility model relates to the technical field of resin sand production and processing, in particular to a dust removal device for a resin sand production line. Background Art

[0002] Resin sand refers to molding sand or core sand that uses artificial synthetic resin as the binder. After the resin sand is made into a mold or core, the resin undergoes an irreversible cross-linking reaction and solidifies through the action of a curing agent, thus giving the mold or core the necessary strength.

[0003] In modern resin sand, when it is used, the resin sand stored in the sand storage is usually poured directly into the device. However, since the resin sand particles in the sand storage are uneven in size and there is a lot of dust adsorbed on the surface, when it is used in the imported equipment, the smaller resin sand can cause the dust to be raised and float around the device, so that the dust raised when the equipment is working is larger, which is more harmful to the surrounding operators. Utility Model Content

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See Figure 1-3As shown, a dust removal device for a resin sand production line includes a tank body 1, a feed pipe 2 is provided on the top wall of the tank body 1, a discharge pipe 3 is provided on the bottom wall of the tank body 1, a top seat 4 is connected to the outer wall of the tank body 1 by interference fit, a plurality of support legs 5 are provided on the outer wall of the top seat 4, and a base 6 is provided between the bottom ends of the plurality of support legs 5;

[0023] The inner wall of the tank body 1 is provided with an outer cylinder 8 through a plurality of connecting blocks 7. The inner wall of the outer cylinder 8 is provided with a plurality of through holes communicating with the inner cavity. One end of a connecting pipe 16 is provided on the outer wall of the outer cylinder 8, and the other end of the connecting pipe 16 extends out of the tank body 1.

[0024] The inner bottom wall of the tank body 1 is rotatably connected to a rotating rod 10 through a bearing 9. An inner cylinder 11 is provided at the top of the rotating rod 10. A plurality of baffles 12 are provided on the inner wall of the inner cylinder 11. A gear 13 is interference fit connected to the outer wall of the rotating rod 10. A motor 14 is also provided on the inner bottom wall of the tank body 1. The output end of the motor 14 is locked with a gear 2 15 through a coupling.

[0025] Furthermore, the connecting pipe 16, the outer cylinder 8 and the through hole are connected, and the dust generated in the inner cylinder 11 is sucked into the outer cylinder 8 through the through hole by the dust removal fan and discharged through the connecting pipe 16 to realize the dust removal operation.

[0026] Furthermore, the inner cylinder 11 is placed in the outer cylinder 8, and the motor 14 drives the gear 2 15 to rotate, and the gear 1 13 drives the rotating rod 10, the inner cylinder 11 and the baffle 12 to rotate. The rotation of the inner cylinder 11 and the baffle 12 causes the material to be tumbled, stirred and dredged, which can make the material tumble and stir in the inner cylinder 11, shake off the dust on the outer wall, and also dredge the material to prevent blockage.

[0027] Furthermore, the inner cylinder 11 is made of a steel mesh material. By making the inner cylinder 11 of the steel mesh material, the dust that is shaken off can float out of the outer side of the inner cylinder 11, making it convenient for the outer cylinder 8 to absorb it.

[0028] Furthermore, the diameter of gear 2 15 is smaller than that of gear 1 13, and they are meshed with each other. The motor 14 causes gear 2 15 to rotate, and the gear 1 13 drives the rotating rod 10, the inner cylinder 11 and the baffle 12 to rotate through gear 2 15, thereby reducing the load of the motor 14 and extending its service life.
