Description

Technical Field

[0001] This invention belongs to the field of shock absorber technology and relates to a detachable dust removal and vibration damping buffer device containing a high-strength, crash-resistant buffer structure. Background Technology

[0002] In the field of dust collectors, the distribution plate and shell of a gas dust collector must withstand significant impact loads. Therefore, vibration damping devices are needed between these two components to ensure the normal operation of the dust collector. Existing vibration damping devices primarily use heat-resistant rubber. While rubber has a significant vibration damping effect, under strong loads, the instantaneous high temperature caused by the impact can easily carbonize the rubber, leading to vibration damping failure. After vibration damping failure, the rigid impact between the two components can cause sparks that ignite the gas, resulting in frequent gas leaks and pipeline surges in the dust collector. Furthermore, vibration damping failure can also lead to component damage and noise caused by impacts. When the vibration or impact velocity of the dust collector exceeds a critical value, the existing dust collector vibration damping devices have poor damping effects. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a detachable dust removal and vibration damping buffer device with a high-strength, drop-resistant buffer structure, which has a better vibration damping effect.

[0004] To achieve the above objectives, this invention discloses a detachable dust removal and vibration damping buffer device containing a high-strength, drop-resistant buffer structure, comprising a lower base steel plate and a top plate. A high-strength aluminum foam core layer is installed on the lower base steel plate, and an upper base steel plate is installed on the high-strength aluminum foam core layer. A spring hydraulic vibration damping structure and a central large spring hydraulic vibration damping structure are provided on the upper base steel plate. The upper ends of the spring hydraulic vibration damping structure and the upper ends of the central large spring hydraulic vibration damping structure are connected to the bottom of the top plate. A drop-resistant buffer structure is also provided between the upper base steel plate and the lower base steel plate.

[0005] Furthermore, the upper steel plate of the base is provided with a lower interface of the spring hydraulic vibration damping structure, the lower end of the spring hydraulic vibration damping structure is provided with a lower spring base, the lower spring base is provided with a lower interface of the fixing bolt, and the lower spring base is fixed to the lower interface of the spring hydraulic vibration damping structure. The upper end of the spring hydraulic vibration damping structure is provided with an upper spring base, the upper spring base is provided with an upper interface of the fixing bolt, the top plate is provided with an upper interface of the spring hydraulic vibration damping structure, and the upper spring base is fixed to the upper interface of the spring hydraulic vibration damping structure. The spring hydraulic vibration damping structure includes a spring bracket and a hydraulic rod. The lower end of the hydraulic rod is connected to the lower interface of the fixing bolt by bolts. The spring bracket is sleeved on the hydraulic rod, and the upper end of the hydraulic rod is connected to the upper interface of the fixing bolt by bolts.

[0006] Furthermore, the top plate is provided with an upper interface of the central large spring hydraulic vibration damping structure, and the upper steel plate of the base is provided with a lower interface of the central large spring hydraulic vibration damping structure. The central large spring hydraulic vibration damping structure includes a central large spring bracket and a central large hydraulic rod. The central large spring bracket is sleeved on the central large hydraulic rod. The upper end of the central large hydraulic rod is fixed to the top plate through the upper interface of the central large spring hydraulic vibration damping structure, and the lower end of the central large hydraulic rod is fixed to the upper steel plate of the base through the lower interface of the central large spring hydraulic vibration damping structure.

[0007] Furthermore, there are four spring-hydraulic damping structures, and one central large spring-hydraulic damping structure.

[0008] Furthermore, each spring hydraulic damping structure is located around the central large spring hydraulic damping structure 7.

[0009] Furthermore, the cross-sectional dimensions of the lower steel plate of the base are the same as those of the cross-sectional dimensions of the top plate.

[0010] Furthermore, the height of the lower steel plate of the base, the high-strength aluminum foam sandwich layer, and the upper steel plate of the base is higher than the height of the top plate.

[0011] Furthermore, the four spring hydraulic damping structures on the upper steel plate of the base have completely identical interface sizes and shapes.

[0012] Furthermore, the interfaces of the four spring-hydraulic vibration damping structures on the top plate are completely identical in size and shape.

[0013] Furthermore, the crash-resistant buffer structure is composed of continuous density gradient aluminum foam material, a metal expansion cylinder, and a conical ring. The continuous density gradient aluminum foam material is filled inside the metal expansion cylinder, and the metal expansion cylinder and the conical ring are connected by a shear pin.

[0014] The present invention has the following beneficial effects: The detachable dust removal and vibration damping buffer device with a high-strength, drop-resistant buffer structure described in this invention, in specific operation, achieves multiple vibration damping effects by setting a central large spring hydraulic vibration damping structure, four sets of spring hydraulic vibration damping structures, and a hydraulic rod-shaped conical ring of a drop-resistant buffer structure. This minimizes the vibration impact and provides a good vibration damping effect.

[0015] Furthermore, the combination of a drop-resistant buffer structure and a high-strength aluminum foam sandwich layer effectively absorbs vibration and impact energy, providing safety assurance during dust collector operation.

[0016] Furthermore, disassembly and installation only require the removal and installation of 4 sets of bolt connections, making disassembly and installation simple and facilitating the relocation of the dust collector's vibration damping and buffer device. Attached Figure Description

The lower interfaces 4 of the spring hydraulic vibration damping structure are configured as four groups, and the lower interface 5 of the central large spring hydraulic vibration damping structure is configured as one group. The four groups of lower interfaces of the spring hydraulic vibration damping structure are... Four spring-hydraulic vibration damping structures 6 are installed on port 4. One central large spring-hydraulic vibration damping structure 7 is installed on the lower interface 5 of one group of central large spring-hydraulic vibration damping structures. A top plate 8 is installed on the spring-hydraulic vibration damping structures 6 and the central large spring-hydraulic vibration damping structures 7. The top plate 8 is provided with upper interfaces 17 of the spring-hydraulic vibration damping structures and upper interfaces 18 of the central large spring-hydraulic vibration damping structures. There are four groups of upper interfaces 17 of the spring-hydraulic vibration damping structures and one group of upper interfaces 18 of the central large spring-hydraulic vibration damping structures. The top plate 8 is also provided with four threaded holes 9.

[0028] The upper end of the spring hydraulic vibration damping structure 6 is provided with a spring upper base 13, and the spring upper base 13 is provided with a fixing bolt upper interface 12. The fixing bolt upper interface 12 is provided with a bolt hole 14. The lower end of the spring hydraulic vibration damping structure 6 is provided with a spring lower base 16, and the spring lower base 16 is provided with a fixing bolt lower interface 15. The spring hydraulic vibration damping structure 6 is configured with 4 sets. The spring hydraulic vibration damping structure 6 includes a spring bracket 10 and a hydraulic rod 11. The lower end of the hydraulic rod 11 is connected to the fixing bolt lower interface 15 by bolts. The spring bracket 10 is set. The hydraulic rod 11 is attached to the upper end of which is connected to the upper interface 12 of the fixing bolt by bolts. The central large spring hydraulic vibration damping structure 7 includes a central large spring bracket 71 and a central large hydraulic rod 72. The central large spring bracket 71 is sleeved on the central large hydraulic rod 72. The upper end of the central large hydraulic rod 72 is fixed to the top plate 8 through the upper interface 18 of the central large spring hydraulic vibration damping structure. The lower end of the central large hydraulic rod 72 is fixed to the upper steel plate 3 of the base through the lower interface 5 of the central large spring hydraulic vibration damping structure, thus restricting the horizontal displacement and rotation of the central large spring hydraulic vibration damping structure 7.

[0029] The cross-sectional dimensions of the lower steel plate 1 of the base are the same as those of the cross-sectional dimensions of the top plate 8. The height of the lower steel plate 1 of the base, the high-strength aluminum foam sandwich layer 2, and the upper steel plate 3 of the base is higher than the height of the top plate 8.

[0030] The four spring hydraulic vibration damping structures on the upper steel plate 3 of the base have completely identical lower interfaces 4, and the four spring hydraulic vibration damping structures on the top plate 8 have completely identical upper interfaces 17, and the four threaded holes 9 on the top plate 8 have completely identical sizes and shapes. The vibration damping device and the dust collector are fixedly installed through the threaded holes 9 using bolts.

[0031] A fall-resistant buffer structure 19 is also provided between the upper steel plate 3 and the lower steel plate 1 of the base. The fall-resistant buffer structure 19 is composed of a continuous density gradient aluminum foam material 191, a metal expansion cylinder 192 and a conical ring 193. The continuous density gradient aluminum foam material 191 is filled in the metal expansion cylinder 192. The metal expansion cylinder 192 and the conical ring 193 are connected by a shear pin. The conical ring 193 is designed as a hydraulic rod. The metal expansion cylinder 192 and the continuous density gradient aluminum foam material 191 serve as energy-absorbing structures, and the metal expansion cylinder 192 can also be used as a load-bearing structure. With the shear pin design, when the vibration or impact speed of the dust collector exceeds the critical value, the metal expansion cylinder 192 will be subjected to a large impact load. When the hydraulic rod-shaped cone ring 193 cannot completely reduce the vibration, the impact load shear pin will break, the crushable and crash-resistant section will start to work, the thin-walled metal expansion cylinder 192 will expand radially, and the continuous density gradient aluminum foam material 191 will be compressed by the cone ring 193 to absorb the impact energy.

[0032] During operation, the central large spring hydraulic vibration damping structure 7 and the four sets of spring hydraulic vibration damping structures 6 on the top plate 8 first absorb a portion of the vibration. The vibration is mainly absorbed by the central large spring support 71 and central large hydraulic rod 72 of the central large spring hydraulic vibration damping structure 7 and the spring support 10 and hydraulic rod 11 of the four sets of spring hydraulic vibration damping structures 6. Then, the remaining vibration is transmitted to the upper steel plate 3 of the vibration base to the cone ring 193 in the form of hydraulic rod for final vibration absorption.

[0033] When the vibration or impact speed of the dust collector exceeds the critical value, part of the vibration is first absorbed by the central large spring hydraulic damping structure 7 and the four sets of spring hydraulic damping structures 6. The vibration is mainly absorbed by the central large spring support 71, the central large hydraulic rod 72, the spring support 10, and the hydraulic rod 11. Then, the second part of the vibration is transmitted from the upper steel plate 3 of the base to the cone ring 193 below for vibration absorption. Finally, the vibration energy is absorbed by the continuous density gradient foam aluminum material 191 and the high-strength foam aluminum sandwich layer 2 of the drop-resistant buffer structure 19.
