Description

Technical Field

[0001] This utility model relates to the field of liquid culture medium filling technology, specifically to an anti-overflow device for liquid culture medium filling. Background Technology

[0002] Liquid culture medium, the counterpart to solid culture medium, is a liquid culture medium for microorganisms or plant and animal cells. It offers advantages for aerated and shaken culture. Under static conditions, a barrier to nutrient permeability forms around the bacterial cells or cultured cells, hindering nutrient uptake. Aeration or shaking eliminates this barrier and increases oxygen supply, thus promoting cell growth and increasing production.

[0003] The patent publication number CN217377260U discloses a filling device with an anti-overflow structure for walnut oil production, including an operating table, a conveyor belt movably connected to the top of the operating table, a control cabinet fixedly connected to the front side of the operating table, a support plate fixedly connected to the top of the operating table, an installation plate fixedly connected to the front side of the support plate, a storage box fixedly connected to the top of the installation plate, and a metering mechanism provided at the bottom of the installation plate.

[0004] As shown in the above technology, during filling, an anti-overflow structure is set on the filling head. In the prior art, the anti-overflow structure consists of a protective cap and an elastic structure. The elastic structure allows the protective cap to press against the bottle mouth to prevent overflow. However, the pressing force is fixed, which may result in the cap being too tight or too loose. If it is too tight, it will damage the bottle mouth. If it is too loose, the anti-overflow effect will be poor. In addition, overflow may also occur at the outlet of the filling head after the filling structure. Utility Model Content

[0022] 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.

[0023] Please see Figures 1-4The overflow prevention equipment for liquid culture medium filling offers two technical solutions:

[0024] The first embodiment includes a filling head 1 and an electromagnetic flow valve 2 fixedly installed on the top of the filling head 1. An anti-overflow component 3 is provided on the outside of the filling head 1, and an anti-overflow component 4 is provided inside the filling head 1.

[0025] The anti-overflow component 3 is used to prevent overflow from the bottle opening of the liquid culture medium, and the anti-overflow component 4 is used to prevent overflow from the outlet of the filling head 1. The anti-overflow component 3 includes a fixing ring 31, which is fixedly connected to the surface of the filling head 1. Two sliding sleeves 32 are fixedly connected to the bottom of the fixing ring 31. T-shaped sliding rods 33 are slidably connected to the inner surfaces of the two sliding sleeves 32. A cap 34 is fixedly connected to one end of each T-shaped sliding rod 33 located below the sliding sleeve 32, and the cap 34 is adapted to fit the bottle opening of the liquid culture medium. Figure 1 As shown, the liquid culture medium consists of a bottle mouth and a bottle body. The bottle mouth is cylindrical and the bottle body is rectangular. A sliding plate 35 is slidably connected to the inner surface of the sliding sleeve 32. A limit spring 36 is fixedly connected between the sliding plate 35 and the end of the T-shaped sliding rod 33. An adjusting bolt 37 is threadedly connected to the top of the fixing ring 31, and the adjusting bolt 37 extends into the interior of the sliding sleeve 32, with the bottom end of the adjusting bolt 37 contacting the top of the sliding plate 35.

[0026] During filling, the bottle opening of the culture medium is capped by the cover plate 34 in the anti-overflow component 3 to prevent overflow. At the same time, the tightness of the cap 34 can be adjusted by the adjusting bolt 37 to avoid being too tight or too loose.

[0027] The second embodiment differs from the first embodiment in that the anti-overflow component 4 includes two arc-shaped plates 41, one at the front and one at the back. Both arc-shaped plates 41 are slidably connected to the inner surface of the filling head 1. A middle rod 42 is fixedly connected between the opposite sides of the two arc-shaped plates 41. A baffle 43 is fixedly connected to the bottom end of the middle rod 42. The baffle 43 is located below the filling port of the filling head 1. A stop rod 45 is fixedly connected to the opposite sides of the two arc-shaped plates 41. Limiting grooves are provided on both the front and back of the filling head 1. The limiting grooves are used to limit the movement of the stop rods 45. Both stop rods 45 extend from the limiting grooves to the outside of the filling head 1. A reset component 44 is provided on both the front and back of the filling head 1. The reset component 44 is used to reset the position of the baffle 43.

[0028] The reset assembly 44 includes a bracket 441, which is fixedly connected to the surface of the filling head 1. A drive motor 442 is fixedly connected to one side of the bracket 441, and an electromagnetic clutch 443 is also fixedly connected to the bracket 441. The output end of the drive motor 442 is fixedly connected to the input end of the electromagnetic clutch 443. A rotating shaft 444 is fixedly connected to the output end of the electromagnetic clutch 443. A cam 445 is fixedly connected to the other end of the rotating shaft 444, and the cam 445 contacts the stop lever 45. The electromagnetic flow valve 2 is connected to an external supply source and is used to control the filling amount. A microcontroller 5 is provided on the front of the electromagnetic flow valve 2. Both the drive motor 442 and the electromagnetic clutch 443 are electrically connected to the microcontroller 5.

[0029] An anti-overflow component 4 is installed inside the filling head to protect the outlet of the filling head after filling, thereby preventing excess culture medium from dripping onto the working area or culture medium, and further improving the anti-overflow effect of the anti-overflow device.

[0030] In use, the filling head 1 moves downwards and the cap 34 covers the bottle opening of the liquid culture medium. At this time, the electromagnetic flow valve 2 opens, and the electromagnetic clutch 443 is disengaged. When the liquid flows to the baffle 43, the baffle 43 opens, and the liquid is poured into the liquid culture medium. The cap 34 protects the bottle opening to prevent overflow. When the filling volume reaches the preset value, the electromagnetic flow valve 2 closes, and the electromagnetic clutch 443 is engaged. The drive motor 442 starts, causing the cam 445 to rotate. The cam 445 rotates and pushes the baffle 45 upwards, which in turn causes the baffle 43 to move upwards, thus closing the outlet of the filling head 1. In addition, if the cap 34 presses too tightly on the liquid culture medium, the pressure mark on the bottle opening can be used to judge the situation. Rotating the adjusting bolt 37 causes the adjusting bolt 37 to move upwards. The upward movement of the adjusting bolt 37 increases the compressible stroke of the limit spring 36, thereby reducing the clamping force of the limit spring 36. Conversely, the adjusting bolt 37 is screwed in.
