Description

Technical Field

[0001] This utility model belongs to the field of shot blasting machine technology, specifically relating to a modification device for reducing the noise of shot blasting machines. Background Technology

[0002] A shot blasting machine is a device that uses a shot blaster to propel shot at high speed onto the surface of a workpiece for cleaning, strengthening, and other purposes. During operation, the high-speed rotation of the shot blaster and the collisions between the shot and the workpiece and internal components generate significant noise. This noise can damage the hearing of operators and negatively impact the surrounding environment. Prolonged exposure to high noise levels can lead to a range of health problems and also violates environmental regulations. While some methods exist for reducing shot blasting machine noise, most have limited effectiveness and fail to address the root cause of excessive noise.

[0003] Therefore, it is very important to design a modification device that can effectively reduce the operating noise of shot blasting machines. Utility Model Content

[0004] This invention aims to overcome the limitations of existing methods for reducing shot blasting machine noise, which are insufficient to fundamentally solve the problem of excessive noise. It provides a modification device for reducing shot blasting machine noise, offering significant sound insulation, good shock absorption, effective buffering and noise reduction, and outstanding noise reduction capabilities.

[0005] To achieve the above-mentioned objectives, this utility model adopts the following technical solution:

[0006] A modification device for reducing the noise of a shot blasting machine includes a shot blasting machine body, with a sound insulation layer provided on the outside of the shot blasting chamber of the shot blasting machine body; a shock-absorbing base is installed at the bottom of the motor of the shot blasting machine; a buffer liner is provided on the inner wall of the shot blasting chamber; the modification device for reducing the noise of the shot blasting machine also includes a shot recovery pipe for noise reduction.

[0007] Preferably, the sound insulation layer is composed of multiple layers of materials, consisting of a sound-absorbing cotton layer, a damping steel plate layer, and a sound-insulating felt layer from the inside out.

[0008] Preferably, the shock-absorbing base includes an upper fixed plate, a lower fixed plate, and a plurality of shock-absorbing springs and shock-absorbing rubber columns disposed between the upper fixed plate and the lower fixed plate.

[0009] Preferably, the damping springs and damping rubber columns are staggered.

[0010] Preferably, the buffer liner is made of an elastic rubber material.

[0011] Preferably, the surface of the buffer liner is provided with multiple irregularly distributed grooves.

[0012] Preferably, the inner wall of the projectile recovery pipe is provided with a sound-absorbing spiral plate.

[0013] Preferably, the silencing spiral blade has multiple silencing holes.

[0014] Compared with the prior art, the advantages of this utility model are: (1) Significant sound insulation effect: By setting a sound insulation layer composed of a sound-absorbing cotton layer, a damping steel plate layer and a sound insulation felt layer outside the shot blasting chamber, noise can be blocked and absorbed from three aspects: sound absorption, vibration reduction and sound insulation, effectively reducing the noise transmitted to the outside during the operation of the shot blasting machine; (2) Good vibration reduction performance: The vibration damping base at the bottom of the shot blasting machine motor can significantly reduce the vibration generated during the operation of the motor through the synergistic effect of the vibration damping spring and the vibration damping rubber column, thereby reducing the noise generated by the vibration and also helping to extend the service life of the motor; (3) Effective buffering and noise reduction: The buffer liner of the shot blasting chamber is made of elastic rubber material and has grooves, which can effectively buffer the impact force of the shot, reduce the noise generated by the collision between the shot and the shot blasting chamber wall, and the irregularly distributed grooves further enhance the noise reduction effect; (4) Outstanding sound reduction function: The sound reduction spiral plate and sound reduction hole in the shot recovery pipe can guide the shot to move smoothly, and absorb the noise generated by the shot moving in the pipe, further reducing the overall operating noise of the shot blasting machine.

[0021] To more clearly illustrate the embodiments of this utility model, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0022] Example:

[0023] like Figure 1 and Figure 2 As shown, this utility model provides a modification device for reducing the noise of a shot blasting machine, including a shot blasting machine body, with a sound insulation layer 1 provided on the outside of the shot blasting chamber of the shot blasting machine body; a shock-absorbing base is installed at the bottom of the motor of the shot blasting machine; a buffer liner 2 is provided on the inner wall of the shot blasting chamber; the modification device for reducing the noise of the shot blasting machine also includes a shot recovery pipe 3 for noise reduction.

[0024] Among them, such as Figure 3 As shown, the sound insulation layer is composed of multiple layers of materials, consisting of a sound-absorbing cotton layer 5, a damping steel plate layer 6, and a sound insulation felt layer 7, from the inside out. By setting a sound insulation layer composed of the sound-absorbing cotton layer, the damping steel plate layer, and the sound insulation felt layer outside the shot blasting chamber, noise can be blocked and absorbed from three aspects: sound absorption, vibration reduction, and sound insulation, effectively reducing the noise transmitted outward during the operation of the shot blasting machine.

[0025] Furthermore, such as Figure 4 As shown, the vibration damping base includes an upper fixed plate 8, a lower fixed plate 9, and multiple damping springs 10 and damping rubber columns 11 disposed between the upper and lower fixed plates; the damping springs and damping rubber columns are staggered. The vibration damping base at the bottom of the shot blasting motor, through the synergistic effect of the damping springs and damping rubber columns, can significantly reduce the vibration generated during motor operation, thereby reducing noise caused by vibration and also helping to extend the service life of the motor.

[0026] Furthermore, the buffer liner is made of elastic rubber material. The surface of the buffer liner has multiple irregularly distributed grooves 4. The buffer liner of the shot blasting chamber wall, made of elastic rubber material and with grooves, effectively buffers the impact force of the shot, reduces noise generated by the collision between the shot and the chamber wall, and the irregularly distributed grooves further enhance the noise reduction effect.

[0027] Furthermore, the inner wall of the shot blasting recovery pipe is provided with a sound-absorbing spiral plate 12. The sound-absorbing spiral plate has multiple sound-absorbing holes 13. The sound-absorbing spiral plate and sound-absorbing holes inside the shot blasting recovery pipe can guide the shot to move smoothly, while absorbing the noise generated by the shot moving within the pipe, further reducing the overall operating noise of the shot blasting machine.

[0028] The specific setup process of this utility model is as follows:

[0029] The modification device for reducing noise in shot blasting machines includes a sound insulation layer installed on the exterior of the shot blasting chamber. This layer consists of a 5cm thick polyester fiber sound-absorbing cotton layer, a 2mm thick damping steel plate layer, and a 3mm thick sound insulation felt layer, arranged from the inside out. A vibration damping base is installed at the bottom of the motor. This base includes an upper fixed plate, a lower fixed plate, and four vibration damping springs and four vibration damping rubber columns positioned between them. The springs have an elastic coefficient of 10N / mm, and the rubber columns have a Shore hardness of 50. The springs and rubber columns are staggered. A buffer liner made of elastic rubber is installed on the inner wall of the shot blasting chamber. This liner has multiple irregularly distributed grooves, each 1cm deep and 0.5cm wide, on its surface. A silencer spiral is installed on the inner wall of the shot recovery pipe. The spiral has a pitch of 10cm, a height of 2cm, and multiple silencer holes.

[0030] The above description is only a detailed explanation of the preferred embodiments and principles of this utility model. For those skilled in the art, there may be changes in the specific implementation methods based on the ideas provided by this utility model, and these changes should also be considered within the protection scope of this utility model.
