Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of reactor structural parts, in particular to a catalyst supporting grid for a reactor. Background Art
[0002] The catalyst support grid of the reactor is a grid structure used to support and fix the catalyst. It is mainly used inside the reactor, especially in the hydrogenation reactor. It can adapt to various harsh working conditions, such as high pressure, high temperature, hydrogen and hydrogen sulfide environment, and has the characteristics of corrosion resistance and wear resistance.
[0003] The catalyst support grid is usually composed of a main beam, a grid and a V-shaped wire mesh. The main beam and the grid are generally made of stainless steel to ensure sufficient strength and rigidity under high temperature and high pressure environments. The V-shaped wire mesh is used to support the catalyst to prevent it from moving or leaking. The catalyst support grid plays a key role in the hydrogenation reactor. It can prevent dirt accumulation on the surface of the filter tube and ensure the effective operation of the catalyst. Its structural design is strong and has a high porosity. It is suitable for liquid filtration in reforming reactors and tanks, and is easy to backwash, has a long service life, and has a low overall cost.
[0004] Currently, the types of catalyst support grids are roughly divided into stainless steel mesh, Johnson mesh and polypropylene filler support grids. The selection and use of these grids depend on the specific industrial application requirements and environmental conditions. Among them, stainless steel mesh catalyst support grids are the most common.
[0005] The support grid structure in the current hydrogenation reactor does not have any obvious drawbacks and can basically meet the normal operation requirements of the hydrogenation reactor. However, the current catalyst support grid does not have an auxiliary reinforcement structure. During the assembly and molding of the catalyst support grid, due to the large number of main beams, calibration and spot welding positioning need to be performed one by one, which takes a lot of time and is not conducive to the efficient assembly operation. In addition, since each main beam is mostly set separately and the industry height error value between the main beams is 0.3mm, during actual use, if some main beams do not bear weight, the force on other load-bearing main beams cannot be effectively transmitted to the non-load-bearing main beams, and the overall force of the grid is easily uneven, which is not convenient for the long-term use of the catalyst support grid.
[0006] In addition, during the "rounding" period of the joints between the grilles, the use of clamps is required to ensure their fit. The welding slag splashes generated during welding can easily cause damage after contact with the clamps, which will cause unnecessary economic burden on the company. Utility Model Content
[0007] The purpose of the utility model is to provide a catalyst support grid for a reactor, which does not require calibration and spot welding of multiple main beams one by one, thereby reducing the working time of assembly personnel. During subsequent use, uneven force on the entire grid is less likely to occur, which facilitates the long-term use of the catalyst support grid, thereby solving the problems raised in the above-mentioned background technology.
[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a catalyst support grid for a reactor, comprising a support grid main body, an auxiliary reinforcement member is provided above the support grid main body, and the auxiliary reinforcement member comprises: two limiting reinforcement beams are provided, and are distributed above the main beams in the plurality of support grid main bodies; a plurality of limiting rods are provided, and are evenly fixed to the side of the limiting reinforcement beam close to the main beam in the support grid main body; a plurality of beam-holding grooves are provided, which are respectively opened on the front and rear sides of the top ends of the plurality of main beams in the support grid main body, and the beam-holding grooves are embedded with the limiting reinforcement beams when in use; a limiting hole is located at the center position of the beam-holding groove, and the limiting hole is opened on the upper surface of the main beam in the support grid main body, and the limiting hole is embedded with the limiting rod when in use.
[0009] Preferably, the end of the limiting rod away from the limiting reinforcement beam is a conical structure.
[0010] Preferably, the depth of the beam-holding groove 1 is the same as the thickness of the limiting reinforcement beam.
[0011] Preferably, a pair of clamping members are provided on the side of the limiting reinforcement beam close to the main beam in the supporting grille body, and the clamping members include: a plurality of clips, which are arranged in pairs and are respectively fixed to the side of the limiting reinforcement beam close to the main beam in the supporting grille body; a plurality of anti-slip convex balls, which are respectively and evenly fixed to the opposite surfaces between the two clips; a plurality of beam-holding grooves are provided, which are respectively opened on the front and rear sides of the top of grille one in the supporting grille body and grille two in the supporting grille body, and beam-holding groove two is embedded with the limiting reinforcement beam when in use.
[0012] Preferably, the top ends of the opposing surfaces between the two clips are provided with an oblique angle.
[0013] Compared with the prior art, the utility model has the following beneficial effects: the catalyst support grid for the reactor has the following advantages over the traditional technology:
[0014] Through the coordination among grille 1, grille 2, wire mesh, main beam, lug, through hole and auxiliary reinforcement, when the assemblers assemble the main beam into grille 1 and grille 2, they first place the limit reinforcement beam inside the beam holding groove 1, and make the limit rod fully inserted into the limit hole. If necessary, they can use a rubber hammer to knock. At this time, the two limit reinforcement beams can limit the multiple main beams. Then, the multiple main beams are placed into grille 1 and grille 2, so that the multiple main beams are evenly distributed inside grille 1 and grille 2. Then, there is no need to calibrate and spot weld the multiple main beams one by one, which has the effect of reducing the working time of the assemblers.
[0015] Through the coordination among Grille 1, Grille 2, wire mesh, main beam, lug, through hole and auxiliary reinforcement parts, after the assemblers stack multiple main beams and two limit reinforcement beams into Grille 1 and Grille 2, they can use electric welding machines to weld and fix multiple main beams to Grille 1 and the grille respectively, and weld and fix the limit reinforcement beams to the main beams. In this way, the limit reinforcement beams can connect multiple main beams. If some main beams do not bear weight, the force on other load-bearing main beams can be effectively transferred to the non-load-bearing main beams through the limit reinforcement beams. During subsequent use, it is not easy for the overall force of the grille to be uneven, which is convenient for the long-term use of the catalyst support grille.
[0016] Through the coordination among Grille 1, Grille 2, wire mesh, main beam, lugs, through holes, auxiliary reinforcements and clamps, the assemblers stack multiple main beams and two limit reinforcement beams into Grille 1 and Grille 2. It should be noted that the limit reinforcement beams need to be partially placed inside the beam holding groove 2, and the anti-skid convex balls on the surface between the clips on both sides will be fully pressed against the fitting surface between Grille 1 and Grille 2. Of course, a rubber hammer can be used to knock when necessary, which can clamp Grille 1 and Grille 2. There is no need to use a clamp for positioning, which avoids the splashing of welding slag generated during welding, which will cause damage to the clamp after contact with the clamp, and will cause unnecessary economic burden on the enterprise.

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] See also Figure 1-7 The utility model provides a technical solution: a catalyst support grid for a reactor, comprising a support grid body, an auxiliary reinforcement member is arranged above the support grid body, and the auxiliary reinforcement member comprises: two limiting reinforcement beams 7 are arranged, and are distributed above the main beams 4 in the multiple support grid bodies; a plurality of limiting rods 8 are arranged, and are evenly fixed to the side of the limiting reinforcement beam 7 close to the main beam 4 in the support grid body; a plurality of beam grooves 9 are arranged, and are respectively opened at the front and rear sides of the top ends of the multiple main beams 4 in the support grid body, and the beam grooves 9 are embedded with the limiting reinforcement beams 7 when in use; a limiting hole 10 is located at the center of the beam groove 9, and the limiting hole 10 is opened on the upper surface of the main beam 4 in the support grid body, and the limiting hole 10 is embedded with the limiting rod 8 when in use.
[0028] It is worth mentioning that the supporting grille body is composed of grille 1, grille 2, wire mesh 3, main beam 4, lug 5 and through hole 6. Grille 2 2 is fixedly connected to both sides of grille 1, wire mesh 3 is fixedly connected to the bottom ends of the inner walls of grille 1 and grille 2, main beams 4 are provided inside grille 1 and grille 2, and there are multiple main beams 4. Multiple lugs 5 are evenly distributed on the edge of the lower surface of wire mesh 3, and the lug 5 is fixedly connected to the contact surface between grille 1 and grille 2, and through hole 6 is opened on the lower surface of lug 5, which passes through lug 5 and wire mesh 3 in sequence.
[0029] In the specific implementation process, it is worth pointing out that the grille 1, the grille 2, the wire mesh 3, the main beam 4, and the lug 5 are all made of stainless steel, which can adapt to various harsh working conditions inside the reactor, such as high pressure, high temperature, hydrogen and hydrogen sulfide environments, and have the characteristics of corrosion resistance and wear resistance. The through hole 6 on the surface of the lug 5 can be used to connect and install the catalyst support grille through bolts or other fasteners. The limiting reinforcement beam 7 and the limiting rod 8 are also made of stainless steel. The outer wall of the limiting rod 8 is fully fitted with the inner wall of the limiting hole 10, and the limiting reinforcement beam 7 can be fully fitted with the inner wall of the beam groove 9.
[0030] Furthermore, the end of the limiting rod 8 away from the limiting reinforcing beam 7 is a conical structure.
[0031] In the specific implementation process, it is worth pointing out that the setting of the conical structure can facilitate the relatively smooth insertion of the limiting rod 8 into the inside of the limiting hole 10, thereby facilitating the smooth progress of the assembly operation.
[0032] Furthermore, the depth of the beam groove 9 is the same as the thickness of the limiting reinforcement beam 7.
[0033] In the specific implementation process, it is worth pointing out that it is necessary to prevent the position-limiting reinforcement beam 7 from being too protruding to affect the normal support of the main beam 4, and the position-limiting reinforcement beam 7 can also provide a certain supporting force.
[0034] Furthermore, a pair of clamping members are provided on the side of the limiting reinforcement beam 7 close to the main beam 4 in the supporting grid body, and the clamping members include: a plurality of clips 11, which are arranged in pairs and are respectively fixed to the side of the limiting reinforcement beam 7 close to the main beam 4 in the supporting grid body; a plurality of anti-slip convex balls 12, which are respectively and evenly fixed to the opposite surfaces between the two clips 11; a plurality of beam-holding grooves 13, which are respectively opened on the front and rear sides of the top of the grid 1 in the supporting grid body and the grid 2 in the supporting grid body, and the beam-holding grooves 13 are embedded with the limiting reinforcement beam 7 when in use.
[0035] In the specific implementation process, it is worth pointing out that the clip 11 is made of stainless steel, and the clip 11 is fully welded and fixedly connected to the limiting reinforcement beam 7, so that the anti-skid convex balls 12 on the inner surface of the clip 11 can be completely sealed, and the anti-skid convex balls 12 will not affect the normal reaction inside the reactor. The anti-skid convex balls 12 are made of rubber material and have great flexibility. The inner wall of the beam groove 13 can fully fit and press against the outer wall of the limiting reinforcement beam 7.
[0036] Furthermore, the top ends of the opposite surfaces between the two clips 11 are provided with bevels 14 .
[0037] In the specific implementation process, it is worth pointing out that the bevel 14 can facilitate the two clips 11 to clamp the grid 1 1 and the grid 2 2, and can also increase the welding contact area between the clips 11 and the grid 1 1 and the grid 2 2.
[0038] Working principle:
[0039] Limiting operations for multiple main beams:
[0040] When the assemblers assemble the main beam 4 into the grille 1 and the grille 2, they first place the limiting reinforcement beam 7 into the beam groove 9 and fully insert the limiting rod 8 into the limiting hole 10. If necessary, they can use a rubber hammer to knock. At this time, the two limiting reinforcement beams 7 can limit the multiple main beams 4. Then, the multiple main beams 4 are placed into the grille 1 and the grille 2, so that the multiple main beams 4 are evenly distributed in the grille 1 and the grille 2. Then, there is no need to calibrate and spot weld the multiple main beams 4 one by one, which reduces the working time of the assemblers. In addition, after the limiting reinforcement beam 7 is welded and fixed to the main beam 4, the limiting reinforcement beam 7 can connect the multiple main beams 4. If some of the main beams 4 do not bear weight, the limiting reinforcement beam 7 can be used to effectively transfer the force on the other load-bearing main beams 4 to the non-load-bearing main beams 4. During subsequent use, it is not easy to have uneven force on the entire grille, which is convenient for the long-term use of the catalyst support grille.
[0041] Limiting operation between grille 1 and grille 2:
[0042] When the assemblers stack the multiple main beams 4 and the two limiting reinforcement beams 7 into the grille 1 and the grille 2, it should be noted that the limiting reinforcement beam 7 needs to be partially placed inside the beam holding groove 2 13, and the anti-skid convex balls 12 on the surface between the clamps 11 on both sides will be fully pressed against the fitting surface between the grille 1 and the grille 2. Of course, if necessary, they can also be knocked with the help of a rubber hammer, which can clamp the grille 1 and the grille 2, and then there is no need to use a clamp for positioning, avoiding the splashing of welding slag generated during welding, which will damage the clamp after contact with it, causing unnecessary economic burden on the enterprise.
[0043] Assembly of the overall structure of the catalyst support grid for the reactor:
[0044] When the assemblers assemble the main beam 4 into the grille 1 and the grille 2, they first place the limiting reinforcement beam 7 into the interior of the beam groove 1 9, and fully insert the limiting rod 8 into the interior of the limiting hole 10. If necessary, they can use a rubber hammer to knock. Then, multiple main beams 4 are placed into the grille 1 and the grille 2, so that multiple main beams 4 are evenly distributed in the grille 1 and the grille 2. In this process, the limiting reinforcement beam 7 needs to be partially placed in the interior of the beam groove 2 13, and the anti-skid convex balls 12 on the surface between the clips 11 on both sides will fully press against the fitting surface between the grille 1 and the grille 2. Of course, if necessary, they can use a rubber hammer to knock. Finally, use an electric welder to weld and fix multiple main beams 4 to the grille 1 and the grille 2, weld and fix the limiting reinforcement beam 7 to the main beam 4, weld the limiting reinforcement beam 7 to the grille 1 and the grille 2, and weld the grille 1 and the grille 2. The assembly operation of the overall structure of the catalyst support grille for the device can be completed.
