Description

Technical Field

[0001] This utility model relates to the technical field of installation structure for flexible ammonia synthesis devices, and in particular to an installation structure for a flexible ammonia synthesis device. Background Technology

[0002] Traditional ammonia synthesis processes primarily obtain raw materials through fossil fuel-based hydrogen production and air separation-based nitrogen production, synthesizing ammonia in a synthesis tower under the action of a catalyst. However, chemical plants using fossil fuels such as coal and natural gas emit large amounts of carbon dioxide during hydrogen production, exacerbating the greenhouse effect. To reduce carbon dioxide emissions and mitigate global warming and other negative impacts, renewable energy sources such as wind, solar, hydro, and geothermal power can be utilized to generate electricity for water electrolysis to produce hydrogen and synthesize ammonia, thereby reducing the use of fossil fuels.

[0003] In existing technologies, most ammonia synthesis plants employ rigid fixing structures, which are difficult to adapt to installation requirements under different operating conditions. This is especially true in situations requiring frequent relocation or position adjustments. Traditional installation structures suffer from inconvenient assembly and disassembly, low positioning accuracy, and poor stability. Furthermore, most installation devices are only suitable for plants of a single size and cannot be adapted to plants of different sizes. This leads to a significant increase in production costs.

[0030] This utility model provides an installation structure for a flexible ammonia synthesis device. Figures 1 to 2An embodiment of the installation structure for the flexible ammonia synthesis device provided by this utility model.

[0031] Traditional ammonia synthesis plants often use rigid fixing methods, directly welding or bolting the equipment to the base. This fixing method can maintain stability under static conditions, but in new energy power generation scenarios, water electrolysis hydrogen production equipment often vibrates due to the intermittent power supply from renewable energy sources, causing mechanical stress between the ammonia synthesis plant and the base. A coastal wind farm's ammonia production system once experienced a situation where frequent vibrations caused the fixing bolts to break, resulting in equipment displacement and the risk of gas leakage.

[0032] Please refer to the following: Figures 1 to 2 The installation structure 100 of the flexible ammonia synthesis unit includes a mounting base 1, a main body 5 of the ammonia synthesis unit, and at least one fixing structure 4. The main body 5 of the ammonia synthesis unit is placed on top of the mounting base 1. The fixing structure 4 includes a mounting frame 43, a positioning plate 42, and a screw 41. The mounting frame 43 is sleeved on the outside of the main body 5 of the ammonia synthesis unit. The screw 41 is rotatably mounted on the top of the mounting base 1 and threadedly connected to the mounting frame 43 to restrict the movement of the mounting frame 43. The positioning plate 42 is threadedly connected to the screw 41 and located on the lower side of the mounting frame 43 to restrict the position of the mounting frame 43.

[0033] Mounting frame 43 refers to the frame structure surrounding the main body 5 of the ammonia synthesis unit. Specifically, it can be made of segmented steel frames spliced ​​together. Its inner diameter is slightly larger than the outer diameter of the equipment to form a clearance fit. Screw 41 refers to a metal rod with external threads. Specifically, it can be a bi-directional threaded rod. It drives the mounting frame 43 to move in the vertical direction through rotation. Positioning plate 42 refers to a flat plate component with a central through hole. Specifically, it can be a hexagonal steel plate. It forms an adjustable support plane on the screw 41 through thread engagement.

[0034] The mounting frame 43 is fitted onto the exterior of the main body 5 of the ammonia synthesis unit, forming a protective constraint. The screw 41 is vertically mounted on the top of the mounting base 1 and threadedly engages with the mounting frame 43. When the equipment vibrates, the operator can rotate the screw 41 to adjust the vertical position of the mounting frame 43, ensuring adequate contact between the mounting frame 43 and the main body of the equipment. Adjusting the position of the positioning plate 42 on the screw 41 changes the support height of the mounting frame 43, creating a dynamic limiting structure that can adapt to different vibration amplitudes. The clearance between the mounting frame 43 and the screw 41 allows for minute displacement of the equipment within a defined range, thereby dissipating vibration energy.

[0035] Therefore, in the technical solution provided by this utility model, the fixing structure 4 includes a mounting frame 43, a positioning plate 42, and a screw 41. The mounting frame 43 is sleeved on the outside of the main body 5 of the ammonia synthesis unit. The screw 41 is rotatably mounted on the top of the mounting base 1 and threadedly connected to the mounting frame 43 to restrict the movement of the mounting frame 43. The positioning plate 42 is threadedly connected to the screw 41 and located on the lower side of the mounting frame 43 to restrict the position of the mounting frame 43. Through the adjustable screw 41 mechanism and the double limiting structure, reliable fixing of the equipment under dynamic working conditions is achieved. The cooperative design of the mounting frame 43 and the screw 41 allows the equipment to make a small displacement within a controllable range, which avoids stress concentration caused by rigid connection and prevents safety hazards caused by excessive displacement of the equipment.

[0036] To address the issue of loosening of the installation structure due to vibration during the operation of an ammonia synthesis unit, a mechanical limiting structure formed by the reinforcing plate 3 and the mounting groove significantly improves the installation stability of the equipment. Specifically, in this embodiment of the invention, a reinforcing plate 3 is provided on the top of the mounting base 1, and a mounting groove is provided on the left side of the reinforcing plate 3. The mounting frame 43 is engaged in the mounting groove to limit the shaking of the mounting frame 43.

[0037] The reinforcing plate 3 is fixed to the top of the mounting base 1 by welding or bolting, and the mounting groove formed on its left side forms a clearance fit with the mounting frame 43. After the mounting frame 43 is fitted onto the outside of the main body 5 of the ammonia synthesis unit, its bottom edge is embedded in the mounting groove, and the lateral displacement is restricted by the contact friction between the groove wall and the side of the mounting frame 43. At this time, after the screw 41 is screwed into the threaded hole of the mounting frame 43, it forms a longitudinal constraint together with the positioning plate 42, so that the main body 5 of the ammonia synthesis unit is stably fixed in three-dimensional space.

[0038] Furthermore, a wear-resistant pad is provided in the mounting groove to prevent the mounting frame 43 from detaching from the mounting groove.

[0039] Wear-resistant pads refer to a buffer material layer set on the inner surface of the mounting groove. Specifically, they can be made of rubber or polyurethane materials and are fixed to the inner wall of the mounting groove by adhesive or snap-fit. Their function is to increase the friction of the contact surface and absorb vibration energy, so as to avoid structural displacement caused by rigid contact between the mounting frame 43 and the mounting groove.

[0040] When the mounting frame 43 is snapped into the mounting groove, the wear-resistant pad is compressed between the outer wall of the mounting frame 43 and the inner wall of the mounting groove. When the ammonia synthesis unit vibrates during operation, the mounting frame 43 is subjected to periodic impact forces. At this time, the wear-resistant pad absorbs the impact energy through elastic deformation, and its high surface friction coefficient increases the static friction between the mounting frame 43 and the mounting groove. For example, when using polyurethane material with a Shore hardness of 60A, the wear-resistant pad can generate a compression of 0.3-0.5mm when subjected to the downward pressure of the mounting frame 43, which can maintain the positioning accuracy of the mounting frame 43 and suppress the vertical displacement of the mounting frame 43 through the material's resilience.

[0041] In order to flexibly adapt to the installation requirements of the main body 5 of ammonia synthesis units of different sizes, and at the same time simplify the maintenance operation process, improve installation efficiency and structural adaptability, in the technical solution of this utility model, the bottom of the reinforcing plate 3 is detachably installed with a limiting block 2, which is slidably connected in the mounting base 1 and is used to adjust the distance between the reinforcing plate 3 and the screw 41.

[0042] The limiting block 2 is slidably embedded in the groove of the mounting base 1. When it is necessary to adjust the distance between the reinforcing plate 3 and the screw 41, the fixing device of the limiting block 2 can be loosened, the limiting block 2 can be moved along the groove to the target position, and then it can be re-fixed. By changing the position of the limiting block 2, the relative distance between the reinforcing plate 3 and the screw 41 changes accordingly, thereby adapting to the installation requirements of the main body 5 of the ammonia synthesis unit of different sizes. For example, when the main body 5 of the ammonia synthesis unit needs to be replaced due to process adjustments, the position of the limiting block 2 can be adjusted to match the size of the new unit without replacing the entire installation structure.

[0043] Furthermore, the limiting block 2 includes a first platform and a second platform, wherein the length or width of the first platform is greater than the length or width of the second platform.

[0044] The limiting block 2 is fixed by a detachable connection between its first part and the bottom of the reinforcing plate 3, while the second part is embedded in a groove inside the mounting base 1. When it is necessary to adjust the distance between the reinforcing plate 3 and the screw 41, the reinforcing plate 3 can be moved laterally by sliding the second part within the groove. The larger size of the first part prevents the limiting block 2 from shifting during sliding, while the smaller size of the second part ensures smooth movement within the groove. Thus, the segmented structure of the limiting block 2 ensures both the adjustability of the distance between the reinforcing plate 3 and the screw 41 and avoids instability of the installation structure due to sliding.

[0045] To address the issue of lateral displacement of the reinforcing plate 3 due to vibration during dynamic operation of an ammonia synthesis unit, in the embodiment provided by this utility model, a plug-in assembly 6 is provided inside the reinforcing plate 3. The plug-in assembly 6 includes a locking block 61 that is plugged into the mounting frame 43, and the locking block 61 is slidably installed inside the reinforcing plate 3 to restrict the left and right movement of the reinforcing plate 3.

[0046] After the mounting frame 43 is embedded in the mounting groove of the reinforcing plate 3, the locking block 61 is pushed into the corresponding groove on the side wall of the mounting frame 43 via the sliding mechanism. At this time, the inclined side of the locking block 61 contacts the mounting frame 43 to form a wedge fit. When the device vibrates during operation, the contact surface between the locking block 61 and the mounting frame 43 generates a counterforce, effectively counteracting the tendency of lateral displacement. The slide rail structure inside the reinforcing plate 3 allows the locking block 61 to move in a direction parallel to the axis of the screw 41, facilitating adjustment of the locking depth according to the position of the mounting frame 43.

[0047] By cooperating with the plug-in component 6 and the movable slot, the stability of the reinforcing plate 3 is maintained while the functions of quick unlocking and automatic reset are realized, which significantly improves the installation efficiency and reduces the operation difficulty. Specifically, the reinforcing plate 3 is provided with a movable slot, and the plug-in component 6 also includes a pull plate 62 and an elastic element 63. The pull plate 62 is located at the end of the locking block 61 away from the mounting frame 43 and is slidably connected in the movable slot. One end of the elastic element 63 is installed at the bottom of the movable slot, and the other end is located at the bottom of the pull plate 62.

[0048] When the position of the reinforcing plate 3 needs to be adjusted, the pull plate 62 can be pulled upwards to slide along the movable groove. At this time, the elastic element 63 is compressed, and the locking block 61 is disengaged from the mounting frame 43, releasing the restriction on the reinforcing plate 3. After the adjustment is completed, the pull plate 62 is released, and the elastic element 63 releases its stored elastic potential energy, pushing the pull plate 62 to drive the locking block 61 to re-insert into the mounting frame 43, thereby restricting the left and right movement of the reinforcing plate 3. During this process, the movable groove guides the sliding path of the pull plate 62 to ensure the insertion accuracy of the locking block 61 and the mounting frame 43.

[0049] In order to achieve a fast and stable insertion effect, and at the same time extend the service life of the locking block 61 and the screw 41, in the embodiment of this utility model, the locking block 61 is inclined to the side facing the screw 41.

[0050] When the screw 41 rotates to adjust the position of the mounting frame 43, the inclined surface of the locking block 61 contacts the outer wall of the screw 41. The inclined surface guides the locking block 61 to slide axially along the screw 41, thus smoothly inserting it into the mounting frame 43. During this process, the contact area between the inclined surface and the screw 41 is optimized, avoiding localized stress concentration caused by right-angled edges, while ensuring a uniform distribution of locking force between the locking block 61 and the mounting frame 43.

[0051] In this utility model, a cushioning pad is provided on the top of the mounting base 1.

[0052] The anti-slip properties of the cushioning pad prevent accidental displacement of the device, improving installation stability and operational safety. The thickness of the cushioning pad can range from 5mm to 20mm, such as a 10mm medium-hardness silicone pad, which provides sufficient shock absorption space while preventing insufficient support due to excessive compression. The edge of the cushioning pad can extend to the side wall of the mounting base 1 to form a covering structure, further preventing pad displacement.

[0053] Relying solely on a single threaded connection to fix the positioning plate 42 can easily lead to loosening of the threaded pair under long-term vibration. In order to ensure that the positioning plate 42 can maintain its positional stability when subjected to dynamic loads, in this utility model, a positioning nut is threadedly connected to the screw 41, and the positioning nut is located on the lower side of the positioning plate 42.

[0054] After the mounting frame 43 is fitted onto the outside of the main body 5 of the ammonia synthesis unit, the mounting frame 43 is driven to move vertically by rotating the screw 41, thus clamping and fixing the mounting frame 43 to the main body 5 of the ammonia synthesis unit. The positioning plate 42 is pre-screwed into the screw 41 and abuts against the bottom of the mounting frame 43. At this time, the positioning nut is screwed from the lower end of the screw 41 to the lower side of the positioning plate 42, and tightened with a tool to form a rigid contact between the positioning plate 42 and the mounting frame 43. When the main body 5 of the ammonia synthesis unit is subjected to external vibration or impact, the positioning nut can prevent the positioning plate 42 from sliding downward along the screw 41, thereby maintaining the clamping force of the mounting frame 43 on the main body 5 of the ammonia synthesis unit.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the concept of the present utility model and using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
