Description

Technical Field

[0001] The present application relates to the technical field of connection platform structures, and in particular to a connection platform structure for an anaerobic fermentation tank. Background Art

[0002] Anaerobic fermentation tanks are fermentation tanks that eliminate oxygen and prevent oxygen from entering or do not supply oxygen. In factories, there are usually multiple anaerobic fermentation tanks. During the fermentation process, the operator needs to move to the top wall of the anaerobic fermentation tank to observe the inside of the tank in order to understand the fermentation status of the substances in the tank. Or when the anaerobic fermentation tank needs maintenance, the operator needs to move to the top wall of the anaerobic fermentation tank to perform maintenance.

[0003] In the related art, a connecting platform is provided between two adjacent anaerobic fermentation tanks, and the two adjacent anaerobic fermentation tanks are respectively a first tank body and a second tank body. The connecting platform includes a supporting main beam, a pedestrian pedal and a guardrail. The two ends of the supporting main beam are respectively fixedly connected to the first tank body and the second tank body, the pedestrian pedal is provided on the supporting main beam, and the guardrail is fixedly connected to the opposite sides of the supporting main beam.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: the weights of the materials contained in the anaerobic fermentation tanks are different, resulting in different settlement heights of the first tank body and the second tank body, causing the supporting main beam to be displaced in the vertical and horizontal directions as the anaerobic fermentation tanks settle. Due to uneven force, the supporting main beam and the anaerobic fermentation tanks exert pulling or pushing force on each other, causing damage to the structure of the connecting platform itself or the tank body. Summary of the invention

[0005] In order to improve the above problems, the present application provides a connection platform structure for an anaerobic fermentation tank.

[0006] The connection platform structure of the anaerobic fermentation tank provided in this application adopts the following technical solution:

[0007] The connecting platform structure of the anaerobic fermentation tank includes a supporting main beam, a pedestrian pedal and a protective railing. The pedestrian pedal is arranged on the supporting main beam, and the protective railing is arranged on two opposite sides along the length direction of the supporting main beam. One end of the supporting main beam is relatively fixed to the first tank body, and the other end is movably connected to the second tank body.

[0008] By adopting the above technical solution, one end of the supporting main beam is relatively fixed to the first tank body. After the first tank body is filled with materials, it settles under the action of gravity, and the first tank body drives the supporting main beam to move downward synchronously. The other end of the supporting main beam is movably connected to the second tank body, and the supporting main beam moves relative to the second tank body, thereby reducing the pulling force on the second tank body when the supporting main beam moves, and reducing the deformation between the supporting main beam and the anaerobic fermentation tank due to mutual pressure or pulling force during the movement, thereby improving the stability of the connection state between the supporting main beam and the anaerobic fermentation tank, and improving the structural stability of the connecting platform.

[0009] Preferably, it also includes a connecting component, which includes a support base, and the support base is fixedly connected to the anaerobic fermentation tank. One end of the supporting main beam is fixedly connected to the support base, and the other end moves relatively with the support base.

[0010] By adopting the above technical solution, the support seat is fixedly connected to the two adjacent anaerobic fermentation tanks. When any one of the tanks sinks and moves downward, the support seat will be driven to move accordingly. One end of the support main beam is fixedly connected to the support seat, and the support seat supports the support main beam. When the support seat moves, the support main beam also tends to move downward. The other end of the support main beam moves relative to the support seat, reducing the downward pulling force generated by the support seat on the support main beam.

[0011] Preferably, it also includes a supporting inclined beam, one end of which is fixedly connected to the side wall of the anaerobic fermentation tank, and the other end of which is fixedly connected to the support seat.

[0012] By adopting the above technical solution, a triangle-like structure is formed between the supporting inclined beam, the supporting seat and the side wall of the anaerobic fermentation tank, so that the connection between the supporting seat and the anaerobic fermentation tank is more stable. The setting of the supporting inclined beam supports the supporting seat, further improves the supporting force of the supporting main beam, and reduces the deformation of the supporting main beam due to its own gravity.

[0013] Preferably, the connection assembly further comprises a reinforcing rib plate, and the reinforcing rib plate is fixedly connected to both the support seat and the tank top wall of the anaerobic fermentation tank.

[0014] By adopting the above technical solution, the support base improves the connection strength with the top wall of the anaerobic fermentation tank through the reinforcing rib plate, making the connection state between the support base and the anaerobic fermentation tank more stable, reducing the possibility of relative displacement between the support base and the anaerobic fermentation tank when subjected to force, and improving the stability of the relative position between the support base and the anaerobic fermentation tank.

[0015] Preferably, it further comprises a limiting assembly, wherein the limiting assembly comprises a limiting upright plate, wherein the limiting upright plate is fixedly connected to a support seat on the second tank body, and the limiting upright plate is located at opposite sides of the supporting main beam.

[0016] By adopting the above technical solution, the supporting main beam is located on the supporting seat and has one end that can move relatively, the limiting vertical plate is fixedly connected to the supporting seat and is located on opposite sides of the supporting main beam, when the first tank body drives the supporting main beam to move, the limiting vertical plate can limit the movement of the supporting main beam in the width direction of the supporting main beam, and guide the movement of the supporting main beam along its own length direction, which can not only realize the flexibility of the connecting structure but also improve the connection stability of the connecting structure, and reduce the possibility of separation of the supporting main beam and the supporting seat.

[0017] Preferably, the guardrail includes a first cross bar, a second cross bar and a sliding connecting rod, the first cross bar is provided with a connecting sliding groove along its length direction, one end of the sliding connecting rod is fixedly connected to the second cross bar, and one end of the sliding connecting rod away from the second cross bar extends into the connecting sliding groove and slides along the length direction of the connecting sliding groove.

[0018] By adopting the above technical solution, the first cross bar and the second cross bar are connected by a sliding connecting rod. During the fermentation process of the substances in the anaerobic fermentation tank, adjacent anaerobic fermentation tanks will be displaced closer to or away from each other. The sliding connecting rod is located in the connecting sliding groove. Due to the existence of the sliding connecting rod, when the first cross bar and the second cross bar are displaced closer to each other, there is a moving space between the first cross bar and the second cross bar so that they are not squeezed by each other; when the first cross bar and the second cross bar are displaced away from each other, the two can also maintain a connection relationship so as not to move to a state of separation from each other.

[0019] Preferably, one end of the supporting main beam close to the limiting vertical plate is hinged with a main beam hinge part.

[0020] By adopting the above technical solution, the main beam hinge is hinged to the supporting main beam. When the supporting main beam is displaced as the anaerobic fermentation tank settles, the main beam hinge rotates relative to the supporting main beam under the action of the supporting seat's contact force, but always remains connected to the supporting seat, thereby maintaining a relatively stable connection between the supporting main beam and the supporting seat, reducing the possibility of separation between the supporting main beam and the supporting seat.

[0021] Preferably, limiting rods are provided on opposite sides of the hinged portion of the main beam, and limiting holes are provided on the limiting vertical plates, and the limiting holes are for the limiting rods to extend into.

[0022] By adopting the above technical solution, the main beam hinge is located between the two limit plates. When the main beam hinge moves relative to the limit plates, the limit rod always slides in the limit hole, so that the main beam hinge and the limit plates maintain a connection relationship. The limit hole and the limit plates cooperate to limit the movement and rotation of the main beam hinge.

[0023] Preferably, one end of the limiting rod away from the main beam hinge portion is connected to a limiting block, and the limiting block abuts against the plate surface of the limiting vertical plate.

[0024] By adopting the above technical solution, during installation and construction, the supporting main beam and the main beam hinge are connected to the support seat, and then the limit plate is connected to the support seat. The limit rod is rotated to connect the limit rod and the main beam hinge, and then the limit block is connected to the end of the limit rod away from the main beam hinge and abutted against the limit plate. The installation operation is simple and convenient.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Through the arrangement of the support seat, the support inclined beam and the support main beam, the support seat is fixedly connected to the adjacent anaerobic fermentation tank, and the support main beam is connected to the anaerobic fermentation tank through the support seat. One end of the support main beam is fixedly connected to the support seat, and the other end is movably connected to the support seat. When the anaerobic fermentation tank is filled with materials, it is relatively displaced with the adjacent anaerobic fermentation tank under the action of gravity. The support main beam moves with the tank body, and one end of the movably connected reduces the pressure or thrust exerted on each other between the support seat and the support main beam, thereby reducing damage to the connection platform structure. One end of the support inclined beam is fixedly connected to the side wall of the anaerobic fermentation tank, and the other end is fixedly connected to the support seat. A triangular structure is formed between the support inclined beam, the support seat and the anaerobic fermentation tank, thereby improving the connection strength between the support seat and the anaerobic fermentation tank, and thereby improving the connection stability between the anaerobic fermentation tank and the connection platform.

[0027] 2. Through the arrangement of the main beam hinge, the limit plate and the limit block, the main beam hinge is connected to the limit plate through the limit rod and the limit block. When the supporting main beam is displaced, the main beam hinge rotates relative to the supporting main beam under the action of the abutting force of the support seat, thereby reducing the mutual squeezing or pulling force generated between two adjacent anaerobic fermentation tanks, reducing the possibility of damage to adjacent anaerobic fermentation tanks and the connection platform, maintaining a connection between the supporting main beam and the support seat, and improving the stability of the connection platform structure.

[0035] The following is combined with Figure 1-6 This application is described in further detail.

[0036] Embodiment 1:

[0037] The present application embodiment discloses a connection platform structure of an anaerobic fermentation tank, such as Figure 1 As shown, it includes a connecting component 3 and a supporting main beam 4. The supporting main beam 4 is connected to two adjacent anaerobic fermentation tanks through the connecting component 3. The two adjacent anaerobic fermentation tanks are respectively a first tank body 1 and a second tank body 2. The two ends of the supporting main beam 4 are respectively a first end and a second end. The first end of the supporting main beam 4 is fixedly connected to the first tank body 1, and the second end of the supporting main beam 4 is movably connected to the second tank body 2.

[0038] like Figure 1 and 2As shown, the anaerobic fermentation tank includes a tank top wall and a tank side wall, and the tank top wall and the tank side wall are fixedly connected. The connecting assembly 3 includes a connecting pad 31, a connecting vertical plate 32, a support seat 34 and a reinforcing rib plate 33. The plate surface of the connecting pad 31 is attached to and fixedly connected with the tank top wall of the first tank body 1, and the connecting vertical plate 32 is fixedly connected with the connecting pad 31. The support seat 34 is made of angle steel, and the support seat 34 includes a first support seat 341. Two first support seats 341 are fixedly connected to the first tank body 1. Each support seat 34 includes a supporting portion 3412 and a connecting portion 3411. The supporting portion 3412 is fixedly connected to the connecting portion 3411, and the connecting portion 3411 is fixedly connected to the plate surface of the connecting vertical plate 32. The first end of the supporting main beam 4 is fixedly connected to the supporting portion 3412. The reinforcing rib plate 33 is fixedly connected to the side of the connecting vertical plate 32 away from the connecting portion 3411, and is fixedly connected to the connecting pad 31 at the same time.

[0039] like Figure 1 , 2 As shown in FIG. 3 , the support seat 34 further includes a second support seat 342, two second support seats 342 are fixedly connected to the second tank body 2, and further includes a limit assembly 8, the limit assembly 8 includes a limit plate 81, and the limit plate 81 is fixedly connected to the connecting portion 3411 of the second support seat 342. The second end of the support main beam 4 is mounted on the support portion 3412 of the second support seat 342, and the second end of the support main beam 4 moves relative to the support portion 3412 of the second support seat 342. The limit plate 81 limits the support main beam 4 in the width direction thereof.

[0040] like Figure 1 , 2 As shown in Figure 3, the connection assembly 3 also includes an inclined beam connection seat 35 and a reinforcement connecting rod 36, and the connection platform structure also includes a supporting inclined beam 5. Two supporting inclined beams 5 are provided on each anaerobic fermentation tank. One end of the inclined beam connection seat 35 is fixedly connected to the tank side wall of the anaerobic fermentation tank. The end of the inclined beam connection seat 35 away from the tank side wall of the anaerobic fermentation tank is preliminarily connected to the supporting inclined beam 5 by installing bolts. The end of the supporting inclined beam 5 away from the inclined beam connection seat 35 is fixedly connected to the support seat 34. After the connection is completed, the position where the inclined beam connection seat 35 and the supporting inclined beam 5 abut is further reinforced by welding. A triangular structure is formed between the supporting inclined beam 5, the support seat 34 and the anaerobic fermentation tank, making the connection state more stable and increasing the support strength of the supporting main beam 4. The two supporting inclined beams 5 on each anaerobic fermentation tank are fixedly connected by the reinforcement connecting rod 36, reducing the positional offset between the two supporting inclined beams 5 that are close to or away from each other, improving the stability of the installation position of the supporting inclined beam 5, and improving the stability of the connection position between the supporting inclined beam 5 and the support seat 34.

[0041] like Figure 1 and 4As shown, a pedestrian pedal 6 is laid on the support main beam 4, and the pedestrian pedal 6 includes a first pedal 61, a second pedal 62 and a sliding connection plate 63. The first pedal 61 is fixedly connected to the first end of the support main beam 4, and the second pedal 62 is fixedly connected to the second end of the support main beam 4. The sliding connection plate 63 is fixedly connected to the side of the second pedal 62 away from the support main beam 4, and the end of the sliding connection plate 63 away from the second pedal 62 is laid on the first pedal 61, and the first pedal 61 and the second pedal 62 are slidingly connected through the sliding connection plate 63. A guardrail 7 is fixedly connected to the support main beam 4 along the length direction, and the guardrail 7 includes a guardrail 71, a first crossbar 72, a second crossbar 73 and a sliding connection rod 74. The guardrail 71 is fixedly connected to the support main beam 4, the first crossbar 72 is fixedly connected to the guardrail 71 at the first end close to the support main beam 4, and the second crossbar 73 is fixedly connected to the guardrail 71 at the second end close to the support main beam 4. The sliding connecting rod 74 and the second cross bar 73 are fixedly connected at one end close to the first cross bar 72. The first cross bar 72 is provided with a connecting sliding groove along its length direction, and the connecting sliding groove is used for the sliding connecting rod 74 to be placed and slide.

[0042] Within the standard sinking range, when the weight of the first tank body 1 after being filled with materials is greater than the weight of the second tank body 2, under the action of gravity, the first tank body 1 moves downward relative to the second tank body 2, and the first tank body 1 drives the first support seat 341 and the first end of the support main beam 4 to move downward, and under the pulling force of the first tank body 1, the second end of the support main beam 4 moves relative to the second support seat 342. During the movement, the second support seat 342 generates an upward abutting force on the second end of the support main beam 4, so that the second end of the support main beam 4 has a tendency to rotate relative to the second support seat 342. The first pedal 61 and the second pedal 62 are displaced away from each other, but due to the existence of the sliding connection plate 63, the first pedal 61 and the second pedal 62 always maintain a connection relationship and do not move to separate from each other; under the pulling force of the first end of the supporting main beam 4, the first cross bar 72 and the second cross bar 73 also move away from each other, but due to the setting of the sliding connection rod 74 and the connecting sliding groove, when moving, the sliding connection rod 74 slides in the connecting sliding groove, and the first cross bar 72 and the second cross bar 73 do not move to separate from each other and can always maintain a state of being connected to each other. The limiting vertical plate 81 limits the movement of the supporting main beam 4 in the width direction of the supporting main beam 4, reducing the possibility of the supporting main beam 4 and the support seat 34 being separated during the movement.

[0043] When the first tank body 1 and the second tank body 2 move toward each other, the first support seat 341 and the first end of the support main beam 4 move with the first tank body 1 toward the second tank body 2, and the first support seat 341 drives the first end of the support main beam 4 to generate thrust on the second support seat 342 and the second end of the support main beam 4. Since the second end of the support main beam 4 is slidably connected to the second support seat 342, the second end of the support main beam 4 slides toward the side away from the first support seat 341, releasing the thrust generated by the first end of the support main beam 4, so that no mutual squeezing force is generated between the first tank body 1 and the second tank body 2, reducing the damage caused to each other by the connection platform structure, the first tank body 1 and the second tank body 2 during thermal expansion and contraction, and improving the connection stability and safety of the connection platform structure.

[0044] The implementation principle of the connection platform structure of the anaerobic fermentation tank in Example 1 of the present application is:

[0045] When the first tank 1 drives the first support seat 341 and the first end of the support main beam 4 to move, the first support seat 341 generates a pulling force on the second end of the support main beam 4, so that the second end of the support main beam 4 slides relative to the second support seat 342. During the movement, the first pedal 61 and the sliding connection plate 63 slide relative to each other, and the first cross bar 72 and the sliding connection rod 74 slide relative to each other. The setting of the sliding connection plate 63 and the sliding connection rod 74 improves the flexibility of the connection platform structure while also improving the connection stability of the connection platform structure.

[0046] Embodiment 2:

[0047] The difference between the second embodiment and the first embodiment is that:

[0048] like Figure 5 and 6As shown, the second end of the supporting main beam 4 is hinged with a main beam hinge part 41, the main beam hinge part 41 is in contact with the second support seat 342, and the main beam hinge part 41 is fixedly connected with a hinge pedal 64 on the side away from the second support seat 342. The limiting assembly 8 also includes a limiting rod 82, which passes through the opposite sides of the main beam hinge part 41 and both ends extend out of the main beam hinge part 41, and the limiting vertical plate 81 is provided with a limiting hole 811 for the limiting rod 82 to pass through and move, and the limiting hole 811 is a waist-shaped hole, and the length direction of the waist-shaped hole is consistent with the length direction of the supporting main beam 4. One end of the limiting rod 82 away from the main beam hinge part 41 is threadedly connected to a limiting block 83, and the limiting block 83 is in contact with a plate surface of the limiting vertical plate 81 on one side away from the main beam hinge part 41. During installation, first, the limiting plate 81 is fixedly connected to the second support seat 342, and then the supporting main beam 4 and the main beam hinge 41 are connected to the first support seat 341 and the second support seat 342. After the supporting main beam 4 and the main beam hinge 41 are connected, they are located between the two limiting plates 81. Then, the limiting rod 82 is passed through the limiting hole 811 and screwed into the main beam hinge 41, and finally the limiting block 83 is connected to the limiting rod 82 to complete the installation.

[0049] The implementation principle of the connection platform structure of the anaerobic fermentation tank in Example 2 of the present application is:

[0050] When the first tank body 1 sinks and moves downward relative to the second tank body 2, the first tank body 1 drives the first support seat 341 and the first end of the supporting main beam 4 to move downward synchronously, and the second end of the supporting main beam 4 drives the main beam hinge 41 to have a downward movement trend, and the second support seat 342 generates an upward abutment force on the main beam hinge 41, so that the main beam hinge 41 rotates counterclockwise relative to the supporting main beam 4. Even when the main beam hinge 41 and the second support seat 342 tend to be relatively separated, the cooperation of the limit rod 82, the limit hole 811 and the limit block 83 can also keep the main beam hinge 41 and the limit vertical plate 81 connected. The same applies when the second tank body 2 sinks and moves downward relative to the first tank body 1. While improving the flexibility of the connecting platform structure, it also improves the connection stability of the connecting platform structure, reduces the mutual squeezing or pulling force generated between the anaerobic fermentation tank and the connecting platform, and reduces the possibility of the connecting platform structure being damaged.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
