Description

Technical Field

[0001] The invention belongs to the technical field of professional shock absorbing equipment, and in particular relates to a shock absorber for a universal pipeline. Background Art

[0002] In the chemical industry, especially in the lithium carbonate production industry, material grinding is one of the important process links in the lithium carbonate preparation process. Therefore, a large number of vibration and screening equipment and powder materials are used in the front-end production process. During the operation of these equipment, special pipe shock absorbers must be used to protect the external connecting pipes to prevent metal fatigue cracking, breakage and other problems caused by long-term severe vibration, so as to meet the process requirements of continuous production.

[0003] At present, conventional pipe shock absorbers on the market are generally made of elastic or flexible materials such as metal woven mesh and bellows. When used in the external pipe vibration isolation condition of such composite vibration equipment, such shock absorbers will quickly experience metal fatigue cracking and breaking due to the inherent characteristics of vibration such as multi-directional, large displacement, long-term and high frequency. In addition, the high temperature transmitted by the material causes the fatigue strength of such shock absorbers to drop to an extremely low level, and even the material cannot withstand high temperatures and directly melts or is damaged. In fact, considering only factors such as load, strength, and vibration displacement, such conventional shock absorbers also require special design, and have certain requirements for installation space, installation position and support bracket load. There are many precautions during on-site installation, and there is no repairable design. Once the elastic material is damaged, the shock absorber must be replaced as a whole. Therefore, it cannot continuously, stably and effectively provide shock absorption and vibration isolation effects under high-frequency composite vibration, and does not have long-term working ability.

The change or adjustment of the relative relationship should also be regarded as the scope of the implementation of the present invention without substantial changes in the technical content. The specific structure can be described with reference to the drawings of the patent application.

[0021] The present invention provides a shock absorber for a universal pipe, Figure 1 , Figure 2 as well as Figure 3 As shown, in this embodiment, it includes a main body 10 for connecting with a universal pipe (not shown in the figure), which includes a cylinder 101 with a accommodating cavity, an upper movable joint assembly flange 102 and a discharge side connecting flange 103; wherein the discharge side connecting flange 103 is connected with the next level process equipment through a pipeline, and this part is the content in the prior art.

[0022] The innovative content of the present invention is that the shock absorber for the universal pipe of the present invention also includes an elastic compensation device 20, which includes a feed side connection flange 201, a cylinder assembly flange 202, an upper movable joint 203, a lower movable joint 204, a first elastic compensation mechanism 205 and a second elastic compensation mechanism 206, wherein the feed side connection flange 201 is embedded in the outer peripheral side wall at the top of the upper movable joint 203, the cylinder assembly flange 202 is screwed with the upper movable joint assembly flange 102 through a plurality of circumferentially distributed screw connectors, the upper movable joint 203 is located above the accommodating cavity, and the lower movable joint 204 extends into the accommodating cavity; both ends of the first elastic compensation mechanism 205 are arranged between the lower surface of the feed side connection flange 201 and the upper surface of the cylinder assembly flange 202 in a quick-detachable manner; both ends of the second elastic compensation mechanism 206 are arranged on the outer side wall of the lower movable joint 204 in a quick-detachable manner; The upper movable joint 203 and the lower movable joint 204 respectively have a matched and ground inner and outer curved ball joints. After being assembled and installed, the connection between the upper movable joint 203 and the lower movable joint 204 forms a surface-sealed movable joint.

[0023] It can be understood that the above-mentioned screw connection member can be a combination of a screw and a nut.

[0024] When using, please combine Figures 1 to 3As shown, the feed side connection flange 201 is used to communicate with the material supply equipment or the input pipeline to input the powder material; the cylinder assembly flange 202 is used to connect with the upper movable joint assembly flange 102 to form the main structural component; the upper movable joint 203 and the lower movable joint 204 respectively have a matching ground inner and outer curved surface ball joint, and after the pair is installed, a face-sealed movable joint is formed, which can be tilted in any horizontal direction while maintaining the seal, and the upper and lower movable joint components also have an axial stroke to compensate for the vibration displacement from the axial direction; the first elastic compensation mechanism 205 and the second elastic compensation mechanism 206 components have compression and elastic reset functions. When the upper movable joint 203 and the lower movable joint 204 are subjected to horizontal vibration displacement forces in any direction from the feed or discharge side, the upper movable joint 203 and the lower movable joint 204 will tilt and swing accordingly. At this time, the first elastic compensation mechanism 205 and the second elastic compensation mechanism 206 form a buffering effect due to the corresponding compression or stretching action to protect the movable joint from damage caused by sudden impact force; when the upper movable joint 203, When the lower movable joint 204 generates downward axial displacement due to vibration, the first elastic compensation mechanism 205 and the second elastic compensation mechanism 206 are compressed and move downward synchronously to generate compression deformation, and convert the external force into potential energy and store it in the elastic body to generate accumulated force. When the axial displacement force disappears, the upper movable joint 203 and the lower movable joint 204 are immediately reset under the push of the reaction force of the first elastic compensation mechanism 205; and the second elastic compensation mechanism 206 also provides sufficient thrust to make the ball joint curved surfaces of the upper movable joint 203 and the lower movable joint 204 always fit together; the elastic compensation device is set in this way, especially through the first elastic compensation mechanism 205 and the second elastic compensation mechanism 206 with surface sealing and elastic compensation mechanism 20, while maintaining sealing, the compensation amount is large, and it has multi-directional displacement compensation functions such as horizontal arbitrary direction and axial vertical, and can realize swinging at any angle in the horizontal direction, which changes the structure of elastic sensitive materials such as bellows and flexible materials used in the prior art, and can continuously, stably and effectively provide shock absorption and vibration isolation effects under high-frequency composite vibration.

[0025] It can be understood that the shock absorber of the present invention has a compact structure and a large compensation amount; the shock absorber of the present invention is suitable for isolating the vibration source of high-frequency, composite vibration polishing grinders, centrifuges, vibrating screens and other equipment, and the aforementioned applications are only some examples and cannot be exhaustive. After the shock absorber inlet and outlet side connection flanges are connected to the equipment and pipelines, it can be put into use automatically without adjustment, and is easy to install and operate.

[0026] Specifically, in this embodiment, the upper movable joint 203 has a smooth outer curved surface, and the lower movable joint 204 has a smooth inner curved surface, and the outer curved surface and the inner curved surface are tightly fitted together to form a good surface contact type sealing pair. In this embodiment, the outer curved surface and the inner curved surface are respectively processed and manufactured by a surfacing process.

[0027] In this example, please refer to Figure 1 and Figure 3 As shown, the first elastic compensation mechanism 205 includes a plurality of first springs distributed along the circumferential direction, one end of the first spring is connected to the lower surface of the feed side connection flange in a quick-detachable manner, and the other end is arranged on the upper surface of the cylinder assembly flange 202 in a quick-detachable manner; The first spring provides a moving space for compensating the axial vibration displacement, and the second elastic compensation mechanism 205 also provides a thrust for closely fitting the ball joint curved surface of the lower movable joint 204 to the ball joint curved surface of the upper movable joint 203. The above structure, especially the quick detachable structure design, is adopted to facilitate the maintenance and replacement of the wearing parts in the later stage.

Through the above design, the surfaces of the upper movable joint 203 and the lower movable joint 204 can be reassembled and ground, so that the formed sealing surface has extremely high smoothness and hardness, and its flexibility, wear resistance and corrosion resistance are strong, which can effectively improve the service life of the movable joint. In special circumstances, when the sealing surface of the movable joint has severe wear or defects, it can be repaired by surfacing and grinding processes, thereby greatly extending the service life of the equipment.

[0029] In this example, please refer to Figure 1 and Figure 3 As shown, the second elastic compensation mechanism 206 includes at least one second spring distributed along the circumferential direction, and both ends of the second spring are arranged between two extension plates extending along the radial direction of the outer side wall of the lower movable joint 204 in a quick-detachable manner.

[0030] It should be noted that the shock absorber of the present invention realizes flexible compensation by elastic elements (first spring and second spring) instead of conventional structures such as metal bellows and flexible materials. The pressure reducer will not be broken or damaged due to metal fatigue, high temperature, material pressure and the like. The shock absorber can continuously, stably and effectively provide a vibration isolation environment for a long time under high-frequency composite vibration. Due to its structural characteristics, even if some elastic compensation elements fail, it will not cause large-scale leakage of materials. The compensation failure cycle can be completely avoided or slowed down by regular inspection and replacement of elastic elements.

[0031] In this embodiment, a replaceable high-temperature resistant soft filling material (not shown in the figure, the same below) is also included. The high-temperature resistant soft filling material is filled in the spacing cavity formed between the lower movable joint 204 and the cylinder 101.

[0032] In this example, please refer to Figure 1 and Figure 3 As shown, positioning slots are symmetrically provided between the lower movable joint 204 and the cylinder 101, and the positioning slots are used to control the moving direction of the lower movable joint 204 to be vertical axial movement, and to protect the second elastic compensation mechanism 206 from distortion and deformation that affects use.

[0033] In this embodiment, the first elastic compensation mechanism 205 is made of high-strength and high-temperature resistant thickened material. With the above design, each component is connected and fixed in a reliable manner, and the whole has extremely high strength and stiffness shock absorber, and there are no high-speed rotating or violently moving parts inside, so the device has an extremely long service life.

[0034] In this embodiment, the second elastic compensation mechanism 206 is made of high-strength and high-temperature resistant thickened material. With the above design, each component is connected and fixed in a reliable manner, and the whole has extremely high strength and stiffness shock absorber, and there are no high-speed rotating or violently moving components inside, so the device has an extremely long service life.

[0035] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.

[0036] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
