Description

Technical Field

[0001] This utility model relates to the field of liquid alkali mixing pipeline technology, specifically to an anti-corrosion protective sleeve for liquid alkali mixing pipelines. Background Technology

[0002] Liquid alkali mixing pipelines refer to pipeline systems used to transport liquid alkali. They are usually made of corrosion-resistant materials to ensure the stability and safety of liquid alkali during transportation. Liquid alkali, namely sodium hydroxide solution, is highly corrosive, so the mixing pipelines also need to have excellent corrosion resistance. At the same time, when using liquid alkali mixing pipelines, anti-corrosion protective sleeves are also required to further enhance the corrosion resistance of the pipelines and ensure the long-term stable operation of the liquid alkali mixing pipelines.

[0003] Existing patent CN210050462U discloses a pipe protective sleeve, including a first clamping sleeve and a second clamping sleeve. The first clamping sleeve and the second clamping sleeve are interlocked to form an annular sleeve. The first clamping sleeve is a semi-circular toroidal stretched body. A slide rail is provided in the middle of one side of the upper surface of the first clamping sleeve, and a slide rail is provided in the middle of the other side. An inner clamping head is provided at one end of the first clamping sleeve along the inner side of the inner cavity, and an outer clamping head of the same height as the inner clamping head is provided on the outer side of the inner cavity. The inner clamping head and the outer clamping head are integrally formed. This utility model solves the problem that existing pipe protective sleeves are all put on the pipe before the pipe is installed. This will cause inconvenience during pipe installation and inconvenience in removing the protective sleeve during pipe maintenance. By improving the structure of the pipe protective sleeve, the pipe protective sleeve is easy to install and remove, and can be reused, thus improving the service life of the pipe protective sleeve.

[0004] The existing technology has the following problems:

[0005] 1. Existing anti-corrosion protective sleeves for liquid alkali mixing pipelines are prone to insecure fixing as the service time increases. This also leads to the protective sleeves loosening or shifting during long-term use, reducing their effectiveness and practicality.

[0006] 2. The existing anti-corrosion protective sleeves for liquid alkali mixing pipelines do not have anti-collision function. This means that when the pipeline is subjected to external impact force, the protective sleeve cannot play a protective role, which makes the pipeline prone to damage, reduces the service life of the pipeline, and fails to meet the usage requirements. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides an anti-corrosion protective sleeve for liquid alkali mixing pipelines. This solves the problem that existing protective sleeves are prone to loosening or displacement over time due to increased usage. Furthermore, the sleeves lack anti-collision functionality, meaning they cannot protect the pipeline from external impacts, leading to easy damage to the pipeline.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a protective sleeve for a liquid alkali mixing pipeline, comprising an upper sleeve body, an anti-collision component at the top of the upper sleeve body, a first connecting plate at the bottom of one side of the upper sleeve body, a first threaded hole at the top of the first connecting plate, a bolt inside the first threaded hole, a first silicone pad on the inner wall of the upper sleeve body, a positioning hole at one bottom of the upper sleeve body, a positioning block inside the positioning hole, a lower sleeve body at the bottom of the positioning block, a second silicone pad on the inner wall of the lower sleeve body, a second connecting plate at the top of one side of the lower sleeve body, and a second threaded hole at the top of the second connecting plate.

[0009] As a preferred embodiment of this utility model, the anti-collision component includes an elastic sleeve, a telescopic rod is provided inside the elastic sleeve, a buffer spring is provided on the outer surface of the telescopic rod, and a balloon is provided at the top of the telescopic rod.

[0010] As a preferred technical solution of this utility model, the elastic sleeve is generally arched, and there are several groups of elastic sleeves arranged in a circular array.

[0011] As a preferred embodiment of this utility model, the balloon is mounted on the telescopic rod by adhesive connection. The telescopic rod is composed of several sets of movable sleeves, and the size of the telescopic rod is adapted to the size of the buffer spring.

[0012] As a preferred embodiment of this utility model, the positions of the first threaded hole and the second threaded hole are respectively arranged to correspond to each other, and the size of the first threaded hole, the size of the bolt, and the size of the second threaded hole are adapted to each other.

[0013] As a preferred embodiment of this utility model, the first silicone pad is installed on the upper sleeve by adhesive connection, and the second silicone pad is installed on the lower sleeve by adhesive connection, wherein the size of the first silicone pad is adapted to the size of the second silicone pad.

[0014] As a preferred embodiment of this utility model, the positioning block and the lower sleeve are integrally formed, the position of the positioning block corresponds to the position of the positioning hole, there are several groups of positioning holes, and the positioning holes are arranged in a straight line at equal intervals.

[0015] Compared with the prior art, this utility model provides a corrosion-resistant protective sleeve for liquid alkali mixing pipelines, which has the following beneficial effects:

[0016] 1. This anti-corrosion protective sleeve for liquid alkali mixing pipelines is designed with a first threaded hole, bolts, a first silicone pad, a positioning hole, a positioning block, a second silicone pad, and a second threaded hole. During installation, the upper and lower sleeves are first fitted against the surface of the pipeline, and the positioning block is inserted into the positioning hole to position the upper and lower sleeves. Then, the bolts connect the first and second threaded holes to reinforce the connection between the upper and lower sleeves. Finally, the cooperation of the first and second silicone pads ensures that the inner walls of the upper and lower sleeves fit more closely to the pipeline surface, further improving the stability and firmness of the protective sleeve. This design avoids the problem of loosening or displacement of the protective sleeve during long-term use, improves the effectiveness of the protective sleeve, and has strong practicality.

[0017] 2. This anti-corrosion protective sleeve for liquid alkali mixing pipelines utilizes an elastic sleeve, a buffer spring, and a balloon. When the pipeline is subjected to external impact, the elastic sleeve first reduces the force of the impact and prevents the impacting object from directly contacting the protective sleeve. Then, the elastic sleeve compresses the balloon, which in turn compresses the buffer spring. Simultaneously, the compression and deformation of the buffer spring and balloon provide multiple buffering effects, weakening and mitigating the impact force, thereby improving the anti-collision effect of the protective sleeve. This design enables the protective sleeve to have anti-collision functionality, preventing damage to the pipeline from external impacts, extending the pipeline's service life, and meeting usage requirements.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a corrosion-resistant protective sleeve for a liquid alkali mixing pipeline, comprising an upper sleeve 1, an anti-collision component 2 at the top of the upper sleeve 1, a first connecting plate 3 at the bottom of one side of the upper sleeve 1, a first threaded hole 4 at the top of the first connecting plate 3, a bolt 5 inside the first threaded hole 4, a first silicone pad 6 on the inner wall of the upper sleeve 1, a positioning hole 7 at one bottom of the upper sleeve 1, a positioning block 8 inside the positioning hole 7, a lower sleeve 9 at the bottom of the positioning block 8, a second silicone pad 10 on the inner wall of the lower sleeve 9, a second connecting plate 11 at the top of one side of the lower sleeve 9, and a second threaded hole 12 at the top of the second connecting plate 11; the first silicone pad 6 is installed on the upper sleeve 1 by adhesive connection, and the second silicone pad 10 is installed on the lower sleeve 9 by adhesive connection, the size of the first silicone pad 6 and the size of the second silicone pad 10 being adapted to each other;

[0025] Specifically, the interaction between the first silicone pad 6 and the second silicone pad 10 facilitates a closer fit between the inner walls of the upper sleeve 1 and the lower sleeve 9 onto the pipe surface, thereby further improving the stability and firmness of the protective sleeve.

[0026] Reference Figure 1 and Figure 4 The anti-collision component 2 includes an elastic sleeve 201, a telescopic rod 202 is provided inside the elastic sleeve 201, a buffer spring 203 is provided on the outer surface of the telescopic rod 202, and a balloon 204 is provided at the top of the telescopic rod 202; the elastic sleeve 201 is arched in shape, and there are several sets of elastic sleeves 201, which are arranged in a ring array.

[0027] Specifically, when the pipeline is subjected to external impact, the elastic sleeve 201 can reduce the impact force and prevent the impacting object from directly contacting the protective sleeve.

[0028] Reference Figure 1 and Figure 4 The balloon 204 is attached to the telescopic rod 202 by adhesive bonding. The telescopic rod 202 is composed of several sets of movable sleeves. The size of the telescopic rod 202 is adapted to the size of the buffer spring 203.

[0029] Specifically, the cushioning spring 203 and the balloon 204 can be squeezed and deformed, which can play a multiple cushioning role, weakening and reducing the impact force generated during the impact, thereby improving the anti-collision effect of the protective cover.

[0030] Reference Figure 1 , Figure 2 and Figure 3 The positions of the first threaded hole 4 and the second threaded hole 12 are set to correspond to each other. The size of the first threaded hole 4 and the size of the bolt 5 are adapted to the size of the second threaded hole 12. The positioning block 8 and the lower sleeve 9 are integrated. The positions of the positioning block 8 and the positioning holes 7 are set to correspond to each other. There are several sets of positioning holes 7, which are arranged in a straight line at equal intervals.

[0031] Specifically: by inserting the positioning block 8 into the positioning hole 7, the upper sleeve 1 and the lower sleeve 9 are positioned, and at the same time, the bolt 5 is used to connect the first threaded hole 4 and the second threaded hole 12 to reinforce the connection between the upper sleeve 1 and the lower sleeve 9.

[0032] The working principle and usage process of this utility model are as follows: During installation, the upper sleeve 1 and the lower sleeve 9 are first attached to the surface of the pipe, and the positioning block 8 on the lower sleeve 9 is inserted into the positioning hole 7 on the upper sleeve 1 to position the upper sleeve 1 and the lower sleeve 9. Then, the first threaded hole 4 on the first connecting plate 3 and the second threaded hole 12 on the second connecting plate 11 are connected by bolts 5 to strengthen the connection between the upper sleeve 1 and the lower sleeve 9. Finally, the cooperation of the first silicone pad 6 and the second silicone pad 10 makes the inner wall of the upper sleeve 1 and the inner wall of the lower sleeve 9 fit the pipe surface more closely, further improving the stability and firmness of the protective sleeve.

[0033] When the pipeline is subjected to external impact force, the elastic sleeve 201 set in the anti-collision component 2 can first reduce the impact force and prevent the impacting object from directly contacting the protective sleeve. Then, the elastic sleeve 201 squeezes the balloon 204 on the telescopic rod 202, which in turn drives the balloon 204 to squeeze the buffer spring 203. At the same time, the buffer spring 203 and the balloon 204 are deformed by compression, which can play a multiple buffering role, weakening and reducing the impact force generated during the impact, thereby improving the anti-collision effect of the protective sleeve.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
