Description

Technical Field

[0001] This invention relates to the field of graphite insulation cylinder technology, and more particularly to a modular assembled graphite insulation cylinder. Background Technology

[0002] The primary function of graphite insulation cylinders is heat preservation and insulation. In processes requiring the maintenance of high-temperature environments or prevention of rapid heat loss, graphite insulation cylinders, with their excellent insulation properties, can effectively reduce heat transfer and maintain stable internal temperatures. Graphite insulation cylinders are typically made of graphite, which possesses good insulation performance and corrosion resistance, allowing them to maintain stable operating conditions for extended periods.

[0003] When graphite insulation cylinders are partially damaged and lose their effectiveness during actual use, the entire cylinder needs to be replaced, which can easily lead to resource waste. A modular graphite insulation cylinder with detachable and reconfigurable components has emerged, which mainly uses an external support frame to limit movement. However, under prolonged high-temperature use, the length of the external support frame may change, resulting in unrestricted connections between adjacent modules and compromised connection tightness. Summary of the Invention

[0004] This invention discloses a modular assembled graphite insulation cylinder, which aims to solve the technical problem that under long-term high-temperature use, the length of the external support may change, which leads to the connection between adjacent modules being unrestricted and the tightness of the connection cannot be guaranteed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular, assembled graphite insulation cylinder includes a top section, multiple middle sections, and a bottom section. The middle sections are stacked vertically. The top section is connected to the uppermost middle section, and the bottom section is connected to the lowermost middle section. The cylinder also includes: a connecting mechanism comprising multiple connecting frames, each movably embedded in the outer circumferential wall of an adjacent top, middle, and bottom section, for establishing connections between adjacent sections and providing tensile force; an outer support mechanism covering the outer circumferential walls of the top, middle, and bottom sections; and a bottom support mechanism connected to the bottom of the bottom section.

[0007] By incorporating a connecting mechanism, the upper and lower arrow-shaped slots at corresponding positions can form a complete bidirectional arrow-shaped slot. Each connecting frame can be inserted into each bidirectional arrow-shaped slot. Under the rebound action of the V-shaped frame, a continuous compressive force towards the center is provided, thereby ensuring the tightness of the connection between adjacent top, middle, and bottom sections of the cylinder. At the same time, since the connection of the connecting mechanism is mainly distributed on the outer circumference of the graphite insulation cylinder, it will not change the inner structure of the graphite insulation cylinder, thus avoiding any impact on the performance of the graphite insulation cylinder.

[0008] In a preferred embodiment, the combined mechanism further includes: a plurality of upward arrow-shaped grooves, equidistantly arranged around the outer circumference of the top section of the cylinder and the middle sections of the cylinder; a plurality of downward arrow-shaped grooves, equidistantly arranged around the outer circumference of the bottom section of the cylinder and the middle sections of the cylinder, wherein the plurality of upward arrow-shaped grooves and the plurality of downward arrow-shaped grooves on the middle sections of the cylinder are arranged alternately in an alternating manner.

[0009] The combined frame includes: a support rod located between corresponding upper and lower arrow-shaped slots; two V-shaped frames fixedly connected to the top and bottom ends of the support rod, respectively, and having elasticity, with multiple grooves provided on the opposite surfaces of the two V-shaped frames; and metal sheets fixedly connected to one side of the outer wall of the support rod in pairs.

[0010] In a preferred embodiment, the bottom support mechanism includes: multiple sliders, which are fixedly connected to the inner circumference of the sleeve at equal intervals; an inner annular bracket, which is movably fitted to the inner circumference of the bottom section of the cylinder, and whose inner circumference is provided with multiple C-shaped through slots at equal intervals, and the multiple sliders are respectively interference-fitted into the multiple C-shaped through slots; and multiple waist-shaped slots, which are provided through the inner wall of the inner annular bracket.

[0011] By incorporating a bottom support mechanism, the bottom section of the cylinder is supported when it is inside the cylinder, reducing the likelihood of cracks forming at the bottom. When the bottom section extends outwards to serve as a support, the bottom of the graphite insulation cylinder can be raised during storage. The waist-shaped groove ensures ventilation, preventing moisture buildup due to poor air circulation and making the storage of graphite insulation cylinders more convenient.

[0012] In a preferred embodiment, the external support mechanism includes: an inner annular groove, disposed on the inner wall of the top end of the top section of the cylinder; an annular insert, movably inserted into the inner annular groove; and an annular top plate, fixedly connected to the outer wall of the top end of the annular insert, with its bottom end movably fitting against the outer wall of the top end of the top section of the cylinder.

[0013] The external support mechanism also includes: multiple hinge frames, which are fixedly connected at equal intervals to the bottom outer wall of the annular top plate; and multiple external support plates, which are equidistantly and movably attached to the circumferential outer walls of the top section, middle section and bottom section of the cylinder, with hinge rods fixedly connected to their top two sides respectively, and are correspondingly hinged to the multiple hinge frames through the hinge rods.

[0014] The external support mechanism further includes: multiple square through slots, which are staggered and arranged on multiple outer support plates, and multiple metal pieces respectively pass through multiple square through slots; multiple arc-shaped support plates, which are respectively fixedly connected to the bottom outer wall of multiple outer support plates, and each arc-shaped support plate has an external thread on its outer wall, and the outer walls of multiple arc-shaped support plates just form a complete external thread.

[0015] The external support mechanism further includes: a sleeve with an internal thread on its inner circumference and meshing with multiple arc-shaped support plates through the internal and external threads; a second annular insert fixedly connected to the inner wall of one side of the sleeve; and a second inner annular groove provided on the inner wall of the bottom end of the bottom section of the cylinder, with the second annular insert movably inserted into the second inner annular groove.

[0016] By incorporating an external support mechanism, multiple external support plates are attached to the outer circumferential walls of the top, middle, and bottom sections of the cylinder to provide lateral restraint for the graphite insulation cylinder. In addition, each set of metal sheets is split outwards after passing through a square slot and bent to fit against the outer wall of the external support plate. This achieves mutual restraint between the lateral and longitudinal restraint structures, making the lateral and longitudinal restraints more stable. The entire structure is connected without bolts, which simplifies operation and ensures the stability of the external support.

[0017] As described above, a modular assembled graphite insulation cylinder includes a top section, multiple middle sections, and a bottom section. The middle sections are stacked vertically. The top section is connected to the uppermost middle section, and the bottom section is connected to the lowermost middle section. The cylinder also includes: a connecting mechanism comprising multiple connecting frames, each movably embedded in the outer circumferential wall of an adjacent top, middle, and bottom section, for establishing connections between adjacent top, middle, and bottom sections and providing tensile force; an outer support mechanism covering the outer circumferential wall of the top, middle, and bottom sections; and a bottom support mechanism connected to the bottom of the bottom section. The modular assembled graphite insulation cylinder provided by this invention has the advantages of convenient disassembly, easy replacement of modules, and maintaining tightness at the connection points of each module through longitudinal limiting.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0025] The modular assembled graphite insulation cylinder disclosed in this invention is mainly used in scenarios where graphite insulation cylinders are used.

[0026] Reference Figure 1 A modular assembled graphite insulation cylinder includes a top section 2, multiple middle sections 3, and a bottom section 4. The middle sections 3 are stacked vertically. The top section 2 is connected to the uppermost middle section 3, and the bottom section 4 is connected to the lowermost middle section 3. The cylinder also includes:

[0027] The connecting mechanism 6 includes multiple connecting frames, each of which is movably embedded in the outer circumferential wall of the adjacent top section 2, middle section 3 and bottom section 2 of the cylinder, for establishing the connection between the adjacent top section 2, middle section 3 and bottom section 2 of the cylinder and providing tensile force;

[0028] The outer support mechanism 1 covers the outer circumferential walls of the top section 2, the middle section 3, and the bottom section 2 of the cylinder;

[0029] The bottom support mechanism 7 is connected to the bottom of the bottom section 4 of the cylinder.

[0030] Reference Figure 2 In a preferred embodiment, the joint mechanism 6 further includes:

[0031] Multiple upward arrow-shaped grooves 601 are equidistantly arranged around the outer circumference of the top section 2 and multiple middle sections 3 of the cylinder;

[0032] Multiple downward arrow-shaped grooves 603 are equidistantly arranged around the outer circumference of the bottom section 4 and the middle sections 3 of the cylinder. Multiple upward arrow-shaped grooves 601 and multiple downward arrow-shaped grooves 603 on the middle sections 3 of the cylinder are arranged in an alternating manner. The corresponding upward arrow-shaped grooves 601 and downward arrow-shaped grooves 603 can form a complete bidirectional arrow-shaped groove. After aligning the positions of the upward arrow-shaped grooves 601 and downward arrow-shaped grooves 603 with the top section 2, the middle section 3 and the bottom section 4 of the cylinder respectively, each joint frame can be inserted into each bidirectional arrow-shaped groove.

[0033] Reference Figure 3 In a preferred embodiment, the assembly frame includes:

[0034] The support rod 605 is located between the corresponding upper arrow-shaped groove 601 and lower arrow-shaped groove 603;

[0035] Two V-shaped brackets 604 are fixedly connected to the top and bottom of the support rod 605 respectively, and are elastic. Multiple grooves 606 are provided on the opposite surfaces of the two V-shaped brackets 604.

[0036] Metal sheets 602, in pairs, are fixedly connected to the outer wall of one side of the support rod 605. Due to the short length of the support rod 605 and the elasticity of the two V-shaped brackets 604, the grooves 606 of the two V-shaped brackets 604 can be respectively fitted against the inner walls of the upper arrow-shaped groove 601 and the lower arrow-shaped groove 603. To ensure the simultaneous engagement of the two V-shaped brackets 604, the support rod 605 is positioned in the middle of the bidirectional arrow-shaped grooves. The two V-shaped brackets 604 will inevitably extend to both sides. Therefore, under the rebound action of the V-shaped brackets 604, a continuous compressive force towards the center will be provided, thereby ensuring... The tightness of the connection between the adjacent top section 2, middle section 3, and bottom section 2 of the cylinder, and the fact that the rebound force of the V-shaped frame 604 is within a certain range, will not cause squeezing damage to the graphite insulation cylinder. The groove 606 can enhance the friction. At the same time, since the connection of the joint mechanism 6 is mainly distributed on the outer circumference of the graphite insulation cylinder, it will not change the inner structure of the graphite insulation cylinder, thus avoiding affecting the performance of the graphite insulation cylinder. Therefore, this structure can achieve the beneficial effects of easy disassembly, easy replacement of each module, and tightness of the connection between each module through longitudinal limiting.

[0037] Reference Figure 2 , Figure 4 In a preferred embodiment, the external support mechanism 1 includes:

[0038] Inner annular groove 101 is provided on the inner wall of the top end of the top section 2 of the cylinder;

[0039] An annular insert 104 is movably inserted into the inner annular groove 101;

[0040] The annular top plate 102 is fixedly connected to the outer top wall of the annular insert 104, and its bottom end is movably attached to the outer top wall of the top section 2 of the cylinder. The annular insert 104 is inserted into the inner annular groove 101 to establish support with the top section 2 of the cylinder.

[0041] The sleeve 110 has an internal thread 111 on its inner circumference wall, and engages with multiple arc-shaped support plates 109 through the internal thread 111 and the external thread 108.

[0042] The annular insert 112 is fixedly connected to the inner wall of one side of the sleeve 110;

[0043] The inner annular groove 113 is set on the inner wall of the bottom end of the bottom section 4 of the cylinder, and the annular insert 112 is movably inserted into the inner annular groove 113, and then the annular insert 112 is inserted into the inner annular groove 113 to establish support with the bottom section 4 of the cylinder.

[0044] Reference Figure 4 In a preferred embodiment, the external support mechanism 1 further includes:

[0045] Multiple hinged frames 103 are fixedly connected at equal intervals to the bottom outer wall of the annular top plate 102;

[0046] Multiple outer support plates 106 are equidistantly and movably attached to the outer circumferential walls of the top section 2, middle section 3, and bottom section 2 of the cylinder. Hinges 105 are fixedly connected to both sides of the top of the plates, and are correspondingly hinged to multiple hinge frames 103 via the hinges 105. The multiple outer support plates 106 attached to the outer circumferential walls of the top section 2, middle section 3, and bottom section 2 of the cylinder provide lateral restraint for the graphite insulation cylinder.

[0047] Reference Figure 4 In a preferred embodiment, the external support mechanism 1 further includes:

[0048] Multiple square through slots 107 are staggered and arranged on multiple outer support plates 106, and multiple metal pieces 602 pass through the multiple square through slots 107 respectively. Each group of metal pieces 602 can pass through the square through slots 107. After passing through, the two metal pieces 602 in each group can be split outward and bent to fit against the outer wall of the outer support plate 106. This can achieve mutual restraint between the lateral limiting structure and the longitudinal limiting structure, making the lateral and longitudinal limiting more stable.

[0049] Multiple arc-shaped support plates 109 are fixedly connected to the bottom outer walls of multiple outer support plates 106, and each arc-shaped support plate 109 has an external thread 108 on its outer wall. The outer walls of multiple arc-shaped support plates 109 form a complete external thread 108. The outer support plates 106 connected by a hinged structure can be folded open to facilitate the insertion of the metal piece 602 during the connection process. The multiple arc-shaped support plates 109 form a complete ring, which is then fully installed by engaging the sleeve 110 with the outside of the ring. The entire structure is connected without bolts, which is simple to operate and ensures the stability of the external support.

[0050] Reference Figure 5 In a preferred embodiment, the bottom support mechanism 7 includes:

[0051] Multiple sliders 702 are fixedly connected at equal intervals to the inner circumference of the sleeve 110;

[0052] The inner annular support 703 is movably fitted to the inner circumferential wall of the bottom section 4 of the cylinder, and multiple C-shaped through slots 701 are equidistantly provided on its inner circumferential wall. Multiple sliders 702 are respectively interference-fitted into the multiple C-shaped through slots 701.

[0053] Multiple waist-shaped grooves 704 are installed through the inner wall of the inner annular support 703. When the slider 702 is interference-fitted into the bottom of the multiple C-shaped through grooves 701, the inner annular support 703 fits perfectly against the inner wall of the bottom section 4 of the cylinder, providing support for the circumferential inner wall of the bottom section 4 of the cylinder. This reduces the possibility of cracks forming at the bottom of the bottom section 4 of the cylinder during use. By rotating and moving the inner annular support 703 up and down, when the slider 702 is interference-fitted into the top of the multiple C-shaped through grooves 701, the inner annular support 703 can extend out of the bottom section 4 of the cylinder as a support. This elevates the bottom of the graphite insulation cylinder when storing it, and the waist-shaped grooves 704 ensure ventilation, thus preventing the graphite insulation cylinder from getting damp due to poor air circulation during storage, making the storage of the graphite insulation cylinder more convenient.

[0054] Working principle: The upper arrow-shaped groove 601 and the lower arrow-shaped groove 603 at corresponding positions can form a complete bidirectional arrow-shaped groove. After aligning the positions of the upper arrow-shaped groove 601 and the lower arrow-shaped groove 603 with the top section 2, the middle section 3, and the bottom section 4 of the cylinder respectively, each combined frame can be inserted into each bidirectional arrow-shaped groove. Due to the short length of the support rod 605 and the elasticity of the two V-shaped frames 604, the grooves 606 sides of the two V-shaped frames 604 can be respectively attached to the inner walls of the upper arrow-shaped groove 601 and the lower arrow-shaped groove 603. To ensure that the two V-shaped frames 604 are inserted simultaneously, the support rod 605 is located in the middle position of the bidirectional arrow-shaped groove, and the two V-shaped frames 604 will inevitably move towards... With both sides extending outwards, the V-shaped frame 604 provides a continuous compressive force towards the center, ensuring the tightness of the connection between the adjacent top section 2, middle section 3, and bottom section 2 of the cylinder. Since the rebound force of the V-shaped frame 604 is within a certain range, it will not cause compression damage to the graphite insulation cylinder. The groove 606 enhances friction. Furthermore, since the connection of the joint mechanism 6 is mainly distributed on the outer circumference of the graphite insulation cylinder, it does not alter the inner structure of the graphite insulation cylinder, thus avoiding any impact on its performance. Therefore, this structure achieves the beneficial effects of easy disassembly, convenient replacement of modules, and maintaining the tightness of the connection between modules through longitudinal limiting.
