Therefore, developing an online monitoring device for fermentation has become an inevitable trend in the industry. This online monitoring device can monitor key parameters in the fermentation process in real time, such as temperature, pH, dissolved oxygen, and pressure, providing strong data support for precise control of the fermentation process.

[0003] However, existing online detection devices for fermentation suffer from leakage problems at the seal between the connecting column and the fermenter, affecting fermentation and data detection. Furthermore, when malfunctions occur during the detection process, the upper and lower shells are difficult to disassemble, hindering timely repairs. Utility Model Content

[0004] This utility model addresses the problems in existing online detection devices for fermentation, such as leakage at the connection point between the connecting column and the fermenter, which affects fermentation and data detection, and the difficulty in disassembling the upper and lower shells and hindering timely repairs when malfunctions occur. The following technical solution is proposed:

[0005] An online detection device for fermentation includes an upper shell, a lower shell fixedly mounted on the bottom surface of the upper shell, a connecting column fixedly mounted at the center of the bottom end of the lower shell, a probe fixedly mounted inside the connecting column, an air bladder provided on the outer ring of one end of the connecting column, a compression ring provided on the top of the air bladder, a guide protrusion provided on the inner ring of the compression ring, and a sealing ring provided on the top of the compression ring.

[0006] The upper housing has height-adjustable ladder components symmetrically fixedly installed on both sides of the interior. A hinge connector is movably installed on one end of each of the two height-adjustable ladder components. A triangular locking rod is movably installed on the outer ring of one end of each hinge connector. A spring is connected to the center of the bottom surface of each of the two triangular locking rods. One end of each spring is welded to the inner wall of the upper housing. Locking fittings are symmetrically fixedly installed on the inner walls of the top of both sides of the lower housing. A button is movably installed on one side of each of the two triangular locking rods at the center of the spring. A rubber sheet is attached to the end face of each of the two triangular locking rods near the locking fitting.

[0007] As a preferred embodiment of the above technical solution, one end of the connecting column is provided with a cylindrical groove.

[0008] As a preferred embodiment of the above technical solution, a threaded groove is provided on the top of the outer surface of the connecting column.

[0009] As a preferred embodiment of the above technical solution, one end of the height-adjustable ladder is threaded with a bolt, and the height-adjustable ladder and the inner wall of the upper shell are fixed together by the bolt.

[0010] As a preferred embodiment of the above technical solution, two holes are symmetrically opened on one end face of the two locking mating parts with the center line as the reference line, and positioning pins are installed in all four holes. The locking mating parts and the lower housing are fixed by the positioning pins.

[0011] As a preferred embodiment of the above technical solution, button holes are provided at both ends of the two upper housings, and the buttons are slidably connected inside the button holes.

[0012] The beneficial effects of this utility model are as follows:

[0013] (1) By rotating the squeezing ring, the guide protrusion on the inner wall of the squeezing ring slides in the threaded groove on the connecting column. The bottom end of the squeezing ring squeezes the air bag downward, closing the gap between the connecting column and the detection port of the fermenter, preventing air leakage from affecting the reaction of the fermented material and the detection of the online device for fermentation.

[0014] (2) When the online detection device for fermentation needs to be maintained, repaired or replaced, the triangular locking device can quickly disassemble the upper and lower shells, making it convenient for staff to operate. No special tools are needed to easily remove the detection device from the fermentation equipment, shortening the maintenance and repair time and improving the availability of the equipment.

[0020] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0021] Example 1: This utility model provides an online detection device for fermentation, such as... Figures 1 to 4 As shown, it includes an upper shell 1, a lower shell 2 fixedly installed on the bottom surface of the upper shell 1, a connecting column 3 fixedly installed at the bottom center of the lower shell 2, a probe head 16 fixedly installed inside the connecting column 3 for detecting the inside of the tank, an air bladder 5 is provided on the outer ring of one end of the connecting column 3, a compression ring 4 is provided at the top of the air bladder 5, a guide protrusion 7 is provided on the inner ring of the compression ring 4, and a sealing ring 6 is provided at the top of the compression ring 4;

[0022] Height-adjustable ladder components 9 are symmetrically fixedly installed on both sides of the upper housing 1. Hinges 13 are movably installed on one end of each height-adjustable ladder component 9. Triangular locking rods 10 are movably installed on the outer ring of one end of each hinge 13. Springs 12 are connected to the center of the bottom surface of each of the two triangular locking rods 10. One end of each spring 12 is welded to the inner wall of the upper housing 1. Locking mating components 11 are symmetrically fixedly installed on the inner walls of the top of both sides of the lower housing 2. Buttons 8 are movably installed on one side of each of the two triangular locking rods 10 at the center of each spring 12. Rubber sheets 15 are attached to the end face of each of the two triangular locking rods 10 near the locking mating component 11. When the triangular locking rods 10 are locked onto the side of the locking mating component 11, the rubber sheets 15 are located between the two, making the locking more stable and preventing the triangular locking rods 10 from loosening.

[0023] like Figure 2 and 3 As shown, a cylindrical groove is provided at one end of the connecting column 3 to provide installation space for the airbag 5 and the compression ring 4, so that the airbag 5 and the compression ring 4 can be stably installed on the connecting column 3.

[0024] like Figure 2 and 3 As shown, a threaded groove is provided on the top of the outer surface of the connecting column 3. The threaded groove provides a clear sliding path for the guide protrusion 7, restricts the movement direction of the guide protrusion 7, and effectively prevents the guide protrusion 7 from being misaligned or offset.

[0025] like Figure 1 and 4 As shown, one end of the height-adjustable ladder component 9 is threaded with a bolt, and the height-adjustable ladder component 9 and the inner wall of the upper housing 1 are fixed together by the bolt, which serves to fix the height-adjustable ladder component 9, effectively prevent the height-adjustable ladder component 9 from shifting, and facilitate the installation and disassembly of the height-adjustable ladder component 9.

[0026] like Figure 1 and 4As shown, two holes are symmetrically opened on one end face of the two locking mating parts 11 with the center line as the reference line. Positioning pins 14 are installed in each of the four holes. The locking mating parts 11 and the lower housing 2 are pressed and fixed by the positioning pins 14, which serves to fix the locking mating parts 11, increase the stability of the locking mating parts 11 after installation, and prevent the locking mating parts 11 from moving or misaligning during use.

[0027] like Figure 1 and 4 As shown, both ends of the two upper housings 1 are provided with button holes. The button 8 is slidably connected inside the button hole. The button hole can limit the button 8 without hindering its movement, thereby preventing the button 8 from shifting and ensuring the operational stability of the button 8.

[0028] Working principle: First, insert the probe 16 of the connecting column 3 into the detection port of the fermentation tank. Then, rotate the squeezing ring 4. The guide protrusion 7 on the inner wall of the squeezing ring 4 slides downward in the threaded groove on the connecting column 3, causing the squeezing ring 4 to rotate downward. Then, the squeezing ring 4 squeezes the air bladder 5 at the bottom. The air bladder 5 expands under pressure, sealing the gap between the connecting column 3 and the detection port of the fermentation tank, preventing air leakage from affecting the fermentation reaction and the detection of the online device for fermentation. By pressing down on the upper housing 1, the sealing ring 6 at the top of the squeezing ring 4 is deformed, increasing the sealing between the connecting column 3 and the lower housing 2. When the online detection device for fermentation malfunctions, press the buttons 8 at both ends. The buttons 8 cause the hinge connector 13 to rotate. The rotation of the hinge connector 13 causes the triangular locking rod 10 to lift outward. The triangular locking rod 10 causes the spring 12 to deform. When the triangular locking rod 10 is lifted higher than the locking engagement 11, the triangular locking rod 10 and the locking engagement 11 disengage. At this time, pull the upper housing 1 outward to complete the disassembly of the upper housing 1 and the lower housing 2.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
