[0029] Embodiments
[0030] In order to obtain the best sound insulation effect of the quartz ore rod mill, the noise characteristics of the quartz ore rod mill are analyzed. The noise of the quartz ore rod mill is mainly caused by three factors: first, the noise caused by impact is the noise generated by the impact and grinding of the grinding medium (iron rod) on the quartz block during the grinding process of the rod mill on the quartz block. This is the largest source of noise of the rod mill, which is mainly because the quartz block and a large number of iron rods in the rod mill cylinder rotate with the cylinder. On the one hand, the quartz block will be extruded by the iron rod and the quartz block, and on the other hand, the iron rod and the quartz block will be continuously hit to the iron rod and the quartz block below the cylinder under the action of gravity after rotating to a certain height. The quartz block will be continuously crushed and ground under the action of impact force and extrusion force, and the iron rod and the quartz block will produce impact sound and generate huge noise when they hit and collide with the iron rod, the quartz block below and the cylinder wall; the second noise source is the vibration of the rod mill. During the rotation of the rod mill, the iron rod and the quartz block in the rod mill cylinder will impact the support of the rod mill when they impact and collide with each other, so as to produce vibration of the whole rod mill. The support of the rod mill and the fixed support surface will continuously produce impact sound; the third noise source is the noise generated by the rotation of the motor. According to different noise sources and different propagation modes of noise, the present application plans to adopt different noise reduction processing methods.

[0037] Before the design of the above device is specifically carried out, it needs to be explained that: the impact noise is the noise formed by the collision between the materials (iron rods and quartz blocks) in the rod mill cylinder and the cylinder wall, which is mainly propagated through the air. For the impact noise, the utility model mainly considers soundproofing treatment for the noise source (rod mill), and sets a soundproof cover outside the rod mill; since the small rod mill adopts intermittent working mode, the quartz ore blocks and iron rods and other grinding media need to be put into the rod mill cylinder before grinding work (feeding), and the quartz powder and iron rods and other materials need to be discharged from the rod mill cylinder after grinding work (discharging), therefore, the utility model is a movable soundproof cover device, when the rod mill needs to be fed and discharged, the soundproof cover is removed, and when grinding is needed, the soundproof cover is moved outside the rod mill. In order to achieve the ideal soundproof effect, the utility model is a full-sealed soundproof cover, the two side surfaces, top surface and rear end of the soundproof cover are sealed and fixed with soundproof boards, the front end of the soundproof cover is set as a movable door, the movable door is also made of soundproof boards, and the movable door is fixed on the soundproof cover with movable door fasteners; soundproof pads are arranged at the bottom end of the two side panels, rear end panel and movable door of the front end of the soundproof cover, so that the bottom end of the soundproof cover and the fixed support surface (generally the ground) of the rod mill are also in a sealed state, and a sealing ring is arranged between the movable door of the front end and the soundproof cover, that is, a sealing ring matched with the movable door is arranged at the front end of the two side panels and top panel in contact with the movable door, so that the movable door and the soundproof cover main body are in a sealed state. In order to facilitate the movement of the soundproof cover, the utility model sets moving supports below the two side panels of the soundproof cover main body, and the soundproof cover device can be moved with the moving supports as supports by a forklift.
[0038] The vibration noise is the noise formed by the continuous impact between the support of the rod mill and the fixed support surface, which is transmitted through the air on one hand and the fixed support surface on the other hand. The utility model firstly considers fixing the rod mill on a certain support surface to reduce the vibration amplitude of the rod mill, thereby reducing the intensity of the vibration noise, and in order to obtain sufficient fixing adhesion, the support surface must have sufficient rigidity and strength; secondly, the resonance problem between the rod mill and the fixed support surface is considered, if resonance occurs between the rod mill and the fixed support surface, the intensity of the vibration noise will be increased, therefore, resonance between the two must be avoided, the utility model selects fixing the rod mill on a support surface with sufficient volume and weight (such as the ground solidified as a whole), to prevent resonance between the fixed support surface and the support of the rod mill; finally, the problem of reducing the vibration intensity between the support of the rod mill and the fixed support surface is considered, the utility model considers arranging a shock-absorbing pad between the support of the rod mill and the fixed support surface, when the mutual impact of the materials in the barrel of the rod mill causes the support of the rod mill to vibrate, the vibration and impact of the support of the rod mill are first transmitted to the shock-absorbing pad, since the shock-absorbing pad has a certain elasticity, the vibration and impact transmitted by the support of the rod mill are mainly reduced and absorbed by the shock-absorbing pad, that is, the shock-absorbing pad not only reduces the noise caused by the vibration of the support of the rod mill, but also reduces the vibration of the fixed support surface caused by the vibration of the support of the rod mill. At the same time, the utility model arranges the rod mill together with the support in the soundproof cover, after arranging the shock-absorbing pad between the support of the rod mill and the fixed support surface, even if there is vibration noise transmitted through the air, this part of the noise will also be effectively controlled by the soundproof cover.
[0039] The motor noise is caused by the friction and other factors of the motor when the motor drives the rod mill to rotate on one hand, and by the vibration of the motor caused by the unbalanced operation of the rod mill on the other hand, and these noises are all transmitted through the air. For the noise generated by the motor, the utility model mainly considers arranging the motor in the soundproof cover to control the motor noise by the soundproof cover, in order to achieve better soundproof effect, the utility model seals the control circuit of the motor by the soundproof pad below the movable door at the front end of the soundproof cover, that is, the control circuit of the motor of the rod mill is arranged in the orientation of the movable door at the front end of the soundproof cover, and the motor control circuit is seamlessly passed out of the soundproof cover by the appropriate holes arranged on the soundproof pad at the bottom end of the movable door.
[0040] It should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model and not to limit, although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the utility model, which should be covered in the scope of the claims of the utility model.
