Description

Technical Field

[0001] This utility model relates to the field of pipeline structure technology, specifically a pipeline structure for a fermenter. Background Technology

[0002] The main function of adding sulfuric acid to a fermenter is as a catalyst to promote chemical reactions. For highly corrosive chemical catalysts like sulfuric acid, the sealing of pipe connections requires special attention to prevent leakage. Current technology typically uses two flanges secured with screws, or a sleeve can be fitted over the connection for further tightening. However, both of these connection structures still carry the risk of catalyst leakage. Furthermore, replacing pipes requires unscrewing the fixing screws, making the process cumbersome. To improve the sealing effect at the connections and optimize the assembly process, a new pipe structure for fermenters has been developed. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pipeline structure for a fermenter, comprising a first connecting pipe and a second connecting pipe, wherein a flange is connected to the end of the first connecting pipe, and a sleeve capable of covering the flange is connected to the end of the second connecting pipe, the sleeve and the flange fitting together, a first PTFE sheet is provided between the straight end face of the inner side of the sleeve and the straight end face of the flange, a second PTFE sheet is provided between the circumferential end face of the inner side of the sleeve and the circumferential end face of the flange, a square embedding hole is provided on the outer circumference of the sleeve, and a pin is provided on the square embedding hole, the side of the pin abutting against the end of the flange away from the first PTFE sheet.

[0005] Preferably, the sleeve, flange and first PTFE sheet are respectively provided with a plurality of first through holes, a plurality of second through holes and a plurality of third through holes, and the plurality of first through holes, a plurality of second through holes and a plurality of third through holes are aligned one by one.

[0006] Preferably, the end face of the first PTFE sheet is provided with anti-slip texture.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. This utility model, by setting a flange and a sleeve, with the flange and sleeve fitting together, and the straight end face of the inner side of the sleeve close to the straight end face of the flange, and a first PTFE sheet between them, forms a first sealing structure. The circumferential end face of the inner side of the sleeve fits together with the circumferential end face of the flange, and a second PTFE sheet between them, forms a second sealing structure. The above two sealing structures further improve the sealing effect between the first connecting pipe and the second connecting pipe, preventing the leakage of catalysts such as sulfuric acid.

[0010] 2. By setting a square embedding hole and a pin, the side of the pin abuts against the end of the flange away from the first PTFE sheet. This structure allows the first connecting pipe and the second connecting pipe to be quickly installed or disassembled, optimizing the installation or disassembly steps and further improving the convenience for the operator.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] Please see Figures 1 to 3This utility model provides an embodiment of a fermenter piping structure, including a first connecting pipe 1 and a second connecting pipe 2. The first connecting pipe 1 is connected to a flange 3 at one end, and the second connecting pipe 2 is connected to a sleeve 4 that can cover the flange 3 at one end. The sleeve 4 is cylindrical and fits into the flange 3. The straight end face of the inner side of the sleeve 4 is close to the straight end face of the flange 3, and a first PTFE sheet 5 is provided between them to form a first sealing structure. The circumferential end face of the inner side of the sleeve 4 is close to the circumferential end face of the flange 3, and a second PTFE sheet 6 is provided between them to form a second sealing structure. The above two sealing structures further improve the sealing effect of the first connecting pipe 1 and the second connecting pipe 2, preventing the leakage of catalysts such as sulfuric acid.

[0017] In this embodiment, the outer circumference of the sleeve 4 is provided with at least two square insertion holes 7, and each of the two square insertion holes 7 is provided with a pin 8. The side of the pin 8 abuts against the end of the flange 3 away from the first PTFE sheet 5. This structure can fix the first connecting pipe 1 and the second connecting pipe 2. Moreover, the above structure facilitates the quick installation or disassembly of the first connecting pipe 1 and the second connecting pipe 2. The first PTFE sheet 5 has a certain elastic effect. The first PTFE sheet 5 forms an outward elastic force on the flange 3. This elastic force can make the flange 3 and the side of the pin 8 fit tightly together to achieve a fixing effect.

[0018] Furthermore, the inner circumferential end face of the sleeve 4 and the circumferential end face of the flange 3 are interference-fitted by the second PTFE sheet 6 to improve the connection and sealing effect.

[0019] The sleeve 4, flange 3 and first PTFE sheet 5 are respectively provided with a number of first through holes 11, a number of second through holes 12 and a number of third through holes 13. The number of first through holes 11, a number of second through holes 12 and a number of third through holes 13 are aligned one by one. The corresponding first through holes 11, second through holes 12 and third through holes 13 are locked and fixed by screws and nuts. With the help of the pin part 8 and the square pin hole 7, the connection effect between the first connecting pipe 1 and the second connecting pipe 2 is further improved.

[0020] Furthermore, the first through hole 11, the second through hole 12, and the third through hole 13 are arranged in a uniform circular array.

[0021] In this embodiment, the end face of the first PTFE sheet 5 is provided with anti-slip texture (not shown in the figure). The anti-slip texture is on the flat end face of the first PTFE sheet 5, and the anti-slip texture deforms under the pressure of the compression body, and tightly fits the flange 3 and the sleeve 4 respectively, which can improve the sealing effect between the first connecting pipe 1 and the second connecting pipe 2.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
