Description

Technical Field

[0001] This application relates to the sampling technology of fermenters, and particularly to a sampling device for fermenters. Background Art

[0002] A fermenter is a commonly used device for microbial fermentation. When microorganisms ferment in a fermenter, in order to ensure the fermentation effect of the microorganisms, it is necessary to sample and detect the fermentation broth at regular intervals.

[0003] Currently, in order to improve the detection effect, it is necessary to sample at multiple liquid levels of the fermenter. However, when the existing sampling device samples, it can often only sample at one position of the fermenter and cannot sample at multiple points simultaneously. Therefore, when sampling, a fermenter needs to be sampled multiple times, which not only makes the operation complex but also has low sampling efficiency. Utility Model Content

A spring is connected between the valve core and the valve body, and a mounting seat is fixed on the valve body, and the mounting seat is connected with the mounting rod;

[0008] When the spring is in a free state, the valve core blocks the valve body;

[0009] The driving structure can drive all the valve cores to move, so that all the valve bodies are in an open state.

[0010] Optionally, the driving structure includes a vertical rod, which is parallel to the mounting rod and simultaneously penetrates through all the mounting seats and is slidably connected with all the mounting seats;

[0026] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts also belong to the scope of protection of the present application.

[0027] As Figures 1-4 shown:

[0028] A sampling device for a fermentation tank provided by an embodiment of the present application includes a mounting rod 1 that can be vertically inserted into the fermentation tank 9. A plurality of one-way valves 2 are provided on the mounting rod 1 and are distributed along the axial direction of the mounting rod 1. The liquid outlet of the one-way valve 2 is detachably and sealingly connected to a sampling cylinder 3.

[0029] Further, the axial direction of the one-way valve 2 is parallel to the axial direction of the mounting rod 1, and the liquid outlet of the one-way valve 2 is located at the lower end of the one-way valve 2. When the one-way valve 2 enters the fermentation liquid and the one-way valve 2 is only subjected to the pressure of the fermentation liquid, the one-way valve 2 is in a closed state, so that when the fermentation liquid moves and does not reach the sampling position, the fermentation liquid will not enter the sampling cylinder 3.

[0030] A drive structure 4 is provided on the mounting rod 1, and the drive structure 4 can simultaneously open all the one-way valves 2.

[0031] In this embodiment, the sampling cylinder 3 is a hollow structure with an open upper end. The open end of the sampling cylinder 3 is detachably and sealingly connected to the liquid outlet of the valve body 201 through a threaded structure.

[0032] During use, first open the sampling port 901 of the fermentation tank 9, insert the mounting rod 1 into the fermentation tank 9. When the mounting rod 1 contacts the bottom of the fermentation tank 9, stop inserting the mounting rod 1. At this time, a plurality of sampling cylinders 3 are located at different liquid levels of the fermentation liquid. Then operate the drive structure 4 to open all the one-way valves 2. After the one-way valves 2 are opened, the fermentation liquid at each position of the one-way valve 2 flows into the sampling cylinder 3 through the one-way valve 2 for sampling. After sampling is completed, operate the drive structure 4 to close all the one-way valves 2. Finally, pull out the vertical rod 401 from the fermentation tank 9, remove the sampling cylinder 3, and transfer the sampling cylinder 3 containing the sample to the detection position for detection work.

[0033] The sampling device for the fermenter provided in this embodiment is equipped with a plurality of one-way valves 2 distributed along the axial direction of the mounting rod 1 on the mounting rod 1. The liquid outlet of the one-way valve 2 is detachably and sealingly connected to a sampling cylinder 3. A driving structure 4 is provided on the mounting rod 1. The driving structure 4 can simultaneously keep all the one-way valves 2 in an open state, so that when sampling the fermentation liquid in the fermenter 9, sampling can be carried out at multiple different liquid levels simultaneously, which not only makes the sampling process simpler and more convenient, but also improves the sampling efficiency.

[0034] In some embodiments of the present application, the one-way valve 2 includes a valve body 201. Inside the valve body 201, there is a valve core 202 that can block the valve body 201 and can move along the axial direction of the valve body 201. A spring 203 is connected between the valve core 202 and the valve body 201. The valve body 201 is fixed with a mounting seat 204, and the mounting seat 204 is connected to the mounting rod 1;

[0035] When the spring 203 is in a free state, the valve core 202 blocks the valve body 201;

[0036] The driving structure 4 can drive all the valve cores 202 to move, so that all the valve bodies 201 are in an open state.

[0037] During use, the staff presses down the driving structure 4 with their hand, that is, makes the driving structure 4 move downward relative to the mounting rod 1. After the driving structure 4 moves downward, the driving structure 4 simultaneously pushes all the valve cores 202 downward. After the valve cores 202 move downward a certain distance, the valve body 201 is completely opened, and the spring 203 is compressed. At this time, the fermentation liquid flows into the valve body 201 and then into the sampling cylinder 3 for sampling. During sampling, it is necessary to keep the driving structure 4 in a pressed state all the time. After sampling is completed, the staff releases the driving structure 4, and the spring 203 resets, pushing the valve core 202 upward to close the valve body 201.

[0038] In some embodiments of the present application, the driving structure 4 includes a vertical rod 401. The vertical rod 401 is parallel to the mounting rod 1, and the vertical rod 401 simultaneously passes through all the mounting seats 204 and is slidably connected to all the mounting seats 204.

[0039] The vertical rod 401 is provided with pushing members 402 that are equal in number to and in one-to-one correspondence with the one-way valves 2. Each pushing member 402 is fixedly connected to the valve core 202 corresponding to it.

[0040] During use, when the vertical rod 401 is pressed down, the vertical rod 401 drives all the pushing members 402 to move downward synchronously. After each pushing member 402 moves downward, it pushes the valve core 202 connected to it downward, making the valve body 201 in an open state.

[0041] In some embodiments of the present application, the mounting seat 204 is sleeved on the mounting rod 1 and slidably connected to the mounting rod 1, and the mounting seat 204 is detachably and fixedly connected to the mounting rod 1. The pushing member 402 is detachably and fixedly connected to the vertical rod 401. Thus, the position of the one-way valve 2 and the position of the pushing member 402 can be adjusted. Not only can the position of the one-way valve 2 be adjusted according to the fermentation broth at different liquid levels, but also the number and position of the one-way valves 2 can be adjusted according to actual sampling requirements.

[0042] In some embodiments of the present application, a first bolt 5 that can tightly press the mounting rod 1 is threadedly connected to the mounting seat 204.

[0043] During use, when the first bolt 5 is rotated and the first bolt 5 tightly presses the mounting rod 1, the fixing of the mounting seat 204 is achieved; when the first bolt 5 is rotated and the first bolt 5 disengages from the mounting rod 1, the mounting seat 204 can be disassembled and assembled or the position of the mounting seat 204 can be adjusted on the mounting rod 1.

[0044] In some embodiments of the present application, a second bolt 6 that can tightly press the vertical rod 401 is threadedly connected to the pushing member 402.

[0045] During use, when the second bolt 6 is rotated and the second bolt 6 tightly presses the vertical rod 401, the fixing of the pushing member 402 is achieved; when the second bolt 6 is rotated and the second bolt 6 disengages from the vertical rod 401, the push rod can be disassembled and assembled or the position of the pushing member 402 can be adjusted on the mounting rod 1.

[0046] In some embodiments of the present application, a first handle 7 is fixed to the upper end of the mounting rod 1. The vertical rod 401 passes through the first handle 7 and is slidably connected to the first handle 7. A second handle 8 located above the first handle 7 is fixed to the upper end of the vertical rod 401.

[0047] During use, only by holding the first handle 7 and the second handle 8 simultaneously and then pressing down the second handle 8, the downward pressing operation of the vertical rod 401 can be achieved to open the one-way valve 2. After sampling is completed, only by releasing the second handle 8, the spring 203 automatically resets, and the closing of the one-way valve 2 can be achieved. Thus, the effect of convenient operation is achieved.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
