Description

Technical Field

[0001] The utility model relates to the technical field of culture medium processing equipment, in particular to a high-efficiency culture medium filter. Background Art

[0002] The culture medium filter is a key tool for aseptic processing in the laboratory, mainly used to remove particulate contaminants, sterilize liquid reagents, and instruments for laboratory reagents, buffers and culture medium solutions. This is an important step to reduce culture contamination. When faced with more culture medium liquid, an efficient culture medium filter can better speed up the work efficiency.

[0003] The prior art also has the following defects during use:

[0004] 1. When filtering, the culture medium filter in the prior art usually allows the culture medium to pass through multiple layers of filtration to achieve the filtering effect, or accelerates the partial filtration efficiency through human intervention, resulting in low overall filtration efficiency and a waste of time and manpower;

[0005] 2. After the filtration is completed, there may be certain problems with the cleaning of the interior of the culture medium filter in the prior art. If the interior cannot be effectively cleaned, it will lead to the subsequent inability to perform normal use.

[0006] In view of this, we propose a high-efficiency culture medium filter to solve the existing problems. Utility Model Content

[0007] The purpose of the utility model is to provide a high-efficiency culture medium filter to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filter for high-efficiency culture medium, comprising a filter body, a discharge port is installed at the bottom of the filter body, an upper connecting port is installed on one side of the upper end of the filter body, a lower connecting port is installed on one side of the lower end of the filter body, an impurity filter layer and a bacteria filter layer are installed inside the filter body, a mounting ring is installed on the top of the filter body, a mounting block is installed on the mounting ring, a telescopic rod is installed on the upper end of the mounting block, a motor assembly is connected to the upper end of the telescopic rod, the telescopic rod passes through the mounting block and is downwardly connected to a sealing compression cover, and the sealing compression cover is located at the top end of the filter body.

[0009] Preferably, rubber blocks are arranged around the sealing compression cover.

[0010] Preferably, the impurity filtering layer is located at the upper end of the bacteria filtering layer, and the heights of the impurity filtering layer and the bacteria filtering layer are located between the upper connecting port and the lower connecting port.

[0011] Preferably, a lower end mounting frame is installed at the lower end of the filter body.

[0012] Preferably, the upper connection port and the lower connection port have the same overall structure.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the process of filtering the culture medium with the filter, the utility model uses the upper motor assembly to push the sealing cover at the upper end of the filter body downward for compression. Through the compression of the sealing cover, the speed of the culture medium passing through the multiple filter layers is accelerated, thereby improving the overall filtering efficiency.

[0015] 2. The utility model provides two sets of upper and lower connection ports on the culture medium filter. When feeding, the material enters through the upper connection port and then the lower connection port is closed. When the material is finished, the discharge port is closed, and the cleaning liquid is connected from the lower connection port. The filter is cleaned by the cleaning liquid and then discharged from the upper connection port to clean the filter. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Embodiment 1

[0022] like Figure 1 , Figure 2 and Figure 3As shown, the utility model proposes a high-efficiency culture medium filter, including a filter body 1, a discharge port 6 is installed at the bottom of the filter body 1, and the discharge port 6 is used to discharge the filtered culture medium, an upper connection port 5 is installed on one side of the upper end of the filter body 1, and a lower connection port 8 is installed on one side of the lower end of the filter body 1. The upper connection port 5 and the lower connection port 8 realize different functions at different stages, and an impurity filter layer 12 and a bacterial filter layer 13 are installed inside the filter body 1. The impurity filter layer 12 and the bacterial filter layer 13 can filter the culture medium liquid more completely. A mounting ring 4 is installed on the top of the filter body 1, and a mounting block 2 is installed on the mounting ring 4. A telescopic rod 3 is installed on the upper end of the mounting block 2. The upper end of the telescopic rod 3 is connected to a motor assembly 9. The motor assembly 9 drives the compression rod to move up and down, so that the compression rod can extend downward, thereby driving the sealing compression cover 10 to move downward. The telescopic rod 3 passes through the mounting block 2 and is downwardly connected to the sealing compression cover 10. The sealing compression cover 10 is located at the top of the inside of the filter body 1. The sealing compression cover 10 is compressed downward, which can make the culture medium pass through the impurity filter layer 12 and the bacteria filter layer 13 faster.

[0023] Furthermore, a rubber block 11 is arranged around the sealing compression cover 10 , and the rubber block 11 can make the sealing compression cover 10 and the inner wall of the filter body 1 fit tightly.

[0024] Furthermore, the impurity filter layer 12 is located at the upper end of the bacteria filter layer 13, and the height of the impurity filter layer 12 and the bacteria filter layer 13 is located between the upper connecting port 5 and the lower connecting port 8. When the impurity filter layer 12 and the bacteria filter layer 13 are in this position, the culture medium liquid can be better filtered and can also be better cleaned.

[0025] Furthermore, a lower mounting frame 7 is installed at the lower end of the filter body 1 , and the mounting frame is used to install the entire filter body 1 .

[0026] Furthermore, the upper connection port 5 and the lower connection port 8 have the same overall structure. The upper port can be used to introduce culture medium liquid and discharge waste liquid after cleaning, and the lower port can be used to introduce cleaning liquid during cleaning.

[0027] The working principle of the high-efficiency culture medium filter based on Example 1 is: first open the upper connecting port 5 and the discharge port 6, close the lower connecting port 8, and introduce the culture medium into the filter body 1 through the upper connecting port 5, and then drive the motor assembly 9 to make the telescopic rod 3 extend and retract downward, driving the sealing compression cover 10 to move, which can speed up the culture medium to pass through the impurity filter layer 12 and the bacteria filter layer 13 quickly, and then be discharged through the discharge port 6. When the filtration is completed, open the lower connecting port 8, close the discharge port 6, and connect the lower connecting port 8 to the cleaning liquid, and use the cleaning liquid to clean the impurity filter layer 12 and the bacteria filter layer 13, and then discharge them from the upper connecting port 5.

[0028] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
