Description

Technical Field

[0001] This utility model relates to the field of bioengineering equipment technology, specifically a non-fully welded serpentine tube fixing bracket for seed tanks. Background Technology

[0002] In the field of bioengineering, the seed tank is the core equipment for culturing seed bacteria. The fixing structure of its internal coil (used for heating, cooling or media transportation) directly affects the stability of the process and the efficiency of equipment operation and maintenance. Currently, most seed tank coil fixing adopts a fully welded structure.

[0003] While it can meet basic fixing requirements, it has significant limitations: On the one hand, the all-welded structure is prone to weld cracking due to medium corrosion and temperature changes during long-term use, leading to medium leakage. This not only pollutes the cultivation environment but also requires shutdown for disassembly and maintenance, significantly reducing production efficiency. On the other hand, the all-welded design creates a rigid connection between the coil and the fixing components, making it difficult to replace or repair the coil separately during later equipment maintenance. It requires destructive disassembly of the entire structure, increasing equipment maintenance costs and operational difficulty.

[0004] To address the aforementioned issues, developing a seed tank coil holder that requires no full welding, provides reliable fixation, and ensures stable medium circulation has become a key requirement for overcoming the shortcomings of existing technologies. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a non-fully welded serpentine tube fixing bracket for seed tanks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a non-fully welded serpentine tube fixing bracket for seed tanks, comprising: a lower housing; an external component, including an upper housing arranged on the lower housing, and a feed inlet arranged on the upper housing; a fixing component, including a fixing pipe welded inside the lower housing; a circulation component, including a circulation pipe I arranged inside the lower housing, and a protrusion arranged on the circulation pipe I; a first limiting component, including a fixing block arranged inside the lower housing, a sliding post I slidably connected to the fixing block, and a clamping block arranged at one end of the sliding post I; and a second limiting component, including a sliding post II slidably connected to the fixing block, and a limiting groove formed on the sliding post I, wherein the sliding post II and the limiting groove cooperate.

[0007] As a further description of the above technical solution:

[0008] The external component includes a latch, one end of which is disposed on the lower housing and the other end of which is disposed on the upper housing.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes: a water inlet, which is located on one side of the fixing pipe; and a groove, which is located on the fixing pipe and engages with a protrusion.

[0011] As a further description of the above technical solution:

[0012] The circulation assembly includes: a second circulation pipe, arranged inside the lower housing and connected to a first circulation pipe; a retaining ball, slidably connected to a protrusion and cooperating with a fixed pipe; and a first spring, one end connected to the protrusion and the other end connected to the retaining ball.

[0013] As a further description of the above technical solution:

[0014] The first limiting component includes: a second spring, one end of which is connected to a fixed block and the other end of which is connected to a first sliding column.

[0015] As a further description of the above technical solution:

[0016] The second limiting component includes: a spring three, one end of which is connected to the fixed block and the other end of which is connected to the sliding column two.

[0017] As a further description of the above technical solution:

[0018] The first circulation pipe is made of stainless steel.

[0019] This utility model has the following beneficial effects:

[0020] The serpentine coil is stably fixed through the collaboration of multiple components. The lower and upper shells are connected by a locking mechanism to form a stable frame. The first sliding post on the fixing block drives the clamping block to clamp the components. The second sliding post, together with the limiting groove and the third spring, locks the position of the first sliding post. The second spring assists the first sliding post in resetting. At the same time, the protrusion of the circulation pipe engages with the groove of the fixed pipe, and the ball is in close contact with the fixed pipe under the action of the first spring. The multiple structures work together to ensure that the serpentine coil and its internal components are not loose, solving the problem of fixing non-fully welded structures.

[0021] Stainless steel circulation pipe 1, together with circulation pipe 2, forms a complete circulation path. The fixed pipeline inlet provides a medium input channel, and each connection part is sealed with a ball and the components are precisely matched to reduce leakage. This not only improves the medium circulation efficiency, but also extends the service life of the circulation system by taking advantage of the corrosion resistance of stainless steel, ensuring stable and reliable medium transmission in the seed tank process.

[0031] Example 1

[0032] like Figures 1 to 4As shown, this embodiment provides a non-fully welded serpentine tube fixing bracket for seed tanks, comprising: a lower housing 1; an external assembly including an upper housing 2 disposed on the lower housing 1, and a feed inlet 3 disposed on the upper housing 2; a fixing assembly including a fixing pipe 5 welded inside the lower housing 1; a circulation assembly including a circulation pipe 7 disposed inside the lower housing 1, and a protrusion 9 disposed on the circulation pipe 7; a first limiting assembly including a fixing block 13 disposed inside the lower housing 1, a sliding post 15 slidably connected to the fixing block 13, and a clamping block 14 disposed at one end of the sliding post 15; and a second limiting assembly including a sliding post 17 slidably connected to the fixing block 13, and a limiting groove 19 formed on the sliding post 15, wherein the sliding post 17 and the limiting groove 19 cooperate.

[0033] Understandable, Figure 1 The diagram only schematically illustrates some of the components included in the snake tube holder; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, the serpentine bracket can also include, compared to Figure 1 More or fewer parts.

[0034] In addition, in this embodiment, the lower shell 1 and the upper shell 2 constitute the main frame of the fixing frame, the feed port 3 is used to input relevant materials; the fixing pipeline 5 provides a fixing foundation inside the shell, the circulation pipeline 7 realizes the internal medium circulation, the protrusion 9 assists the circulation pipeline 7 in cooperating with other components; the fixing block 13 provides an installation foundation for the sliding column 15 and the sliding column 2 17, the sliding column 15 drives the clamping block 14 to move, and the sliding column 2 17 restricts the position of the sliding column 15 by cooperating with the limiting groove 19, forming a non-fully welded snake tube fixing structure for the seed tank, realizing the initial fixing of the snake tube and the construction of the internal medium circulation channel, and the clamping block 14 and the limiting structure initially restrict the position of the components, ensuring the basic function of the fixing frame is realized.

[0035] Specifically, the external component includes a latch 4, one end of which is arranged on the lower housing 1 and the other end of which is arranged on the upper housing 2.

[0036] Specifically, the fixing component includes: a water inlet 6, which is located on one side of the fixing pipe 5; and a groove 10, which is located on the fixing pipe 5 and cooperates with the protrusion 9.

[0037] In a preferred embodiment, the inlet 6 is used to input liquid into the fixed pipe 5. The groove 10 engages with the protrusion 9 on the circulation pipe 7 to achieve a positioning connection between the fixed pipe 5 and the circulation pipe 7, providing a liquid input channel for the fixed pipe 5. At the same time, the cooperation between the groove 10 and the protrusion 9 improves the accuracy and stability of the connection between the fixed pipe 5 and the circulation pipe 7, ensuring a stable medium transmission path.

[0038] Example 2

[0039] Specifically, the circulation assembly includes: a second circulation pipe 8, which is arranged inside the lower housing 1 and connected to a first circulation pipe 7; a retaining ball 11, which is slidably connected to a protrusion 9 and cooperates with a fixed pipe 5; and a first spring 12, which is connected at one end to the protrusion 9 and at the other end to the retaining ball 11.

[0040] In this embodiment, circulation pipe 2 8 is connected to circulation pipe 1 7, extending the medium circulation path; spring 12 provides elastic force, pushing the retaining ball 11 to slide on the protrusion 9, so that the retaining ball 11 is in close contact with the fixed pipe 5, extending the medium circulation path and improving the medium circulation efficiency; through the cooperation of retaining ball 11 and fixed pipe 5 and the elastic action of spring 12, the sealing and stability of the connection between circulation pipe 1 7 and fixed pipe 5 are enhanced, reducing medium leakage.

[0041] Specifically, the first limiting component includes: a second spring 16, one end of which is connected to the fixed block 13, and the other end of which is connected to the first sliding column 15.

[0042] With this configuration, spring 2 16 provides elastic restoring force between fixed block 13 and sliding post 15. When sliding post 15 moves under force, spring 2 16 can drive sliding post 15 to reset, enabling sliding post 15 to have an automatic reset function, ensuring that clamping block 14 continuously and stably clamps and improving the reliability of the first limit assembly in limiting related components.

[0043] Example 3

[0044] Specifically, the second limiting component includes: a spring 18, one end of which is connected to the fixed block 13 and the other end of which is connected to the sliding column 17.

[0045] Among them, spring three 18 provides elastic force between fixed block 13 and sliding column two 17, pushing sliding column two 17 to always maintain a matching state with the limiting groove 19 on sliding column one 15, ensuring that sliding column two 17 and limiting groove 19 are stably matched, avoiding accidental movement of sliding column one 15, enhancing the limiting effect of the second limiting component, and ensuring the stability of the overall structural components.

[0046] Specifically, the material of the circulation pipe 7 is stainless steel.

[0047] In actual use, first open the latch 4 and remove the upper housing 2. Then, the user presses the protrusion 9 at the bottom of the circulation pipe 7 into the groove 10 on the fixed pipe 5. The locking ball 11 compresses the spring 12. When it reaches the groove, the locking ball 11 resets under the action of the spring 12 to achieve connection. Similarly, the connection between the circulation pipe 8 and the circulation pipe 7 is the same. Then, the user pulls the sliding column 17 upward to release the restriction on the limiting groove 19 on the sliding column 15. Under the action of the spring 16, the sliding column 15 slides outward to fix the circulation pipe 7 and the circulation pipe 8. When it is necessary to release, the sliding column 15 can be pulled backward to reach the position of the limiting groove 19 to achieve locking.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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.
