Large cradle intermittent swing type microorganism biochemical shaker

Abstract

The invention relates to a large cradle intermittent swing type microorganism biochemical shaker, wherein a driving motor is arranged on the bottom plate inside an outer shell, the driving motor and a rotation disk form belt transmission through a belt, the rotation disk is hinged to the frame on the bottom portion of a cradle through a connection rod, the cradle is connected to the bracket on the top portion of the outer shell through a plurality of flexible ropes, the driving motor is connected to a control circuit, the control circuit is connected to the power supply flashboard fixed on the outer portion of the outer shell, a temperature and humidity control device is connected to a control panel through a circuit, the top portion on the inner wall of the outer shell is provided with a sterilization device, the top portion on the side surface of the outer wall of the outer shell is provided with an air filter, and the sterilization device and the air filter are connected to the control panel through circuits. According to the present invention, by using the multi-point supporting lifting type structure, the shaking of the large-batch culture bottles can be performed in one time; the vibration amplitude of the cradle can be adjusted by using the adjustable crank rocker mechanism, and by using the timing circuit to control the variable frequency motor, the shaker is controlled to intermittently shake according to a certain time interval.

Description

technical field [0001] The invention belongs to the technical field of microorganism cultivation equipment, in particular to a large-scale cradle intermittent swing type microorganism biochemical shaker. Background technique [0002] Shakers are often used in conjunction with incubators and shakers or used alone. They are suitable for shaking culture of various liquid and solid compounds such as biology, biochemistry, cells, algae, and bacteria. Currently, shakers on the market have the following problems during use : (1) Most of the current shakers use a plane shaker, and a main shaft is used for shaking. Due to the limitation of the weight of the main shaft, only a limited number of culture bottles can be shaken and cultivated at a time, and the shaking of the shaker during the shaking process The noise is high, and the friction and wear are large; (2) Due to the use of a single-axis oscillating drive device, the shaking range of the shaking table cannot be adjusted, and t...

[0002] Shakers are often used in conjunction with incubators and shakers or used alone. They are suitable for shaking culture of various liquid and solid compounds such as biology, biochemistry, cells, algae, and bacteria. Currently, shakers on the market have the following problems during use : (1) Most of the current shakers use a plane shaker, and a main shaft is used for shaking. Due to the limitation of the weight of the main shaft, only a limited number of culture bottles can be shaken and cultivated at a time, and the shaking of the shaker during the shaking process The noise is high, and the friction and wear are large; (2) Due to the use of a single-axis oscillating drive device, the shaking range of the shaking table cannot be adjusted, and the shaking range cannot meet the requirements, which will make it unable to reach the bacterial liquid within a unit time. Quality requirements, shaking efficiency is very low, and shake flasks take a long time; (3) In order to save electric energy or achieve special cultivation purposes (such as the requirements of patent ZL 201210425277.X), the culture flask needs to be set as Shake at a certain time interval, but the currently commonly used vibration device does not meet the segmental timing device, and it is impossible to achieve interval timing shaking, so that the energy consumption is large or the specific cultivation purpose cannot be achieved, which affects the cultivation efficiency

(4) Existing oscillators start and stop too fast, which may easily cause liquid splashing in the culture bottle, or manual adjustment of the speed controller is required to ensure that the start and stop can achieve slow start and slow stop, and automatic control cannot be realized

(5) At present, there is no shaking culture equipment on the market that can meet the special requirements of some fungi or algae microorganisms for light intensity (such as patents ZL200810002772, 201010230374, 201010230330 and the liquid culture of Nostoc algae that involve light requirements)
