Description

Technical Field

[0001] The utility model relates to the technical field of heating devices, in particular to a water bath constant temperature heating device for an enzyme. Background Art

[0002] Enzyme preparations are enzyme products with catalytic functions that have been purified and processed. They are widely used because of their high catalytic efficiency, mild action conditions and reduced energy consumption. Enzyme preparations need to be heated in a water bath at a constant temperature during processing to ensure the normal production of the enzyme preparations.

[0003] Constant temperature water bath devices are widely used in drying, concentration, distillation, impregnation of chemical reagents, impregnation of drugs and biological preparations, and can also be used for constant temperature heating of water baths and other temperature tests. They are essential tools for biological, genetic, virus, aquatic, environmental protection, medicine, health, biochemical laboratories, and analytical room education and scientific research. However, the existing water bath constant temperature device is not easy to recycle the water, which leads to turbidity of the water after long-term use of the device, affecting the growth of cells and bacteria.

[0004] Therefore, a water bath thermostatic oscillator for preparing a water-circulating enzyme preparation, as proposed in the patent with publication number CN218359344U, has a reasonable structure, can recycle water, keep the water inside the device clean, reduce water waste, and improve environmental protection. However, even for a water bath thermostatic device with water circulation, some water vapor will evaporate, and in order to ensure stable and balanced air pressure, a vent is required to connect to the atmospheric pressure. During use, water needs to be replenished according to the water level of the device, and replenishing water will cause an imbalance in the water bath temperature near the water inlet, which is likely to affect the activity of the enzyme.

[0005] Therefore, the patent with publication number CN216864189U proposes an automatic water adding device for enzyme reaction constant temperature water bath, which preheats the spare water in advance and directly adds the spare water when replenishing water to improve the temperature stability of the water bath. However, preheating the spare water in advance consumes more heat, increases unnecessary energy consumption, and adds additional devices and operations. Utility Model Content

[0006] The utility model aims to provide an enzyme water bath thermostatic heating device to solve the technical problems that water replenishment in the existing water bath thermostatic device easily causes temperature fluctuations and preheating in advance increases unnecessary energy consumption.

[0007] The embodiments of the present invention are implemented by the following technical solutions:

[0008] The invention discloses a water bath thermostatic heating device for enzymes, comprising a water bath, a water tank for providing constant temperature water and a control center for controlling the water level and water temperature of the water tank. The water bath is also provided with a spiral coil for uniform water replenishment and a baffle for blocking and diverting the water replenishment. The baffle is also rotatably provided with a rotating shaft for stirring.

[0009] Preferably, the spiral coil is provided with an electric one-way valve for preventing backflow, and the electric one-way valve is electrically connected to the control center.

[0010] Preferably, a lifting connection is provided between the water bath and the water tank, the lifting connection comprising a telescopic cylinder connected to the water tank and a telescopic rod connected to the water bath, and an emergency stop button electrically connected to the electric one-way valve for controlling its closing is provided at the bottom of the telescopic cylinder.

[0011] Preferably, the lifting connection member is also provided with an elastic member for rebounding the telescopic rod to prevent accidental touching of the emergency stop button.

[0012] Preferably, the water bath is also provided with a liquid level meter for detecting the water level and feeding it back to the control center, and a temperature detection device for detecting the temperature and feeding it back to the control center.

[0013] Preferably, the water tank is further provided with a plurality of groups of heating wires located on both sides of the baffle for heating.

[0014] Preferably, the rotating shaft passes through the baffle and is provided with a first stirring blade for stirring the water flow below the baffle and a second stirring blade for stirring the water flow above the baffle.

[0015] Preferably, the spiral coil is also provided with a plurality of groups of drainage holes for drainage.

[0016] By adopting this technical solution, the replenishing water can be evenly discharged through the spiral coil, and then the replenishing water is dispersed by the stirring of the first stirring blade and heated by the heating wire at the same time. The first stirring blade stirs and transports in a spiral shape, and has an axial lifting effect while stirring in the radial direction. After the replenishing water at the bottom is lifted to the baffle, it is diverted by the baffle and exchanged and mixed with the water flow on the upper layer of the baffle, which can quickly improve the mixing degree of the system materials and the heat dispersion degree;

[0017] At the same time, the water replenishment height is automatically controlled by the liquid level gauge and the emergency stop button. When the liquid level is lower than the specified height of the liquid level gauge, the control center opens the electric one-way valve to start water replenishment. When the liquid level is too high or the water in the water tank floats the water bath to the top and triggers the emergency stop button to close the electric one-way valve and stop water replenishment.

[0018] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0019] 1. The utility model can quickly improve the system material mixing degree and heat dispersion degree through spiral coil water replenishment, baffle diversion and two-side stirring;

[0020] 2. The utility model can automatically open and close the water replenishment according to the water level change and the buoyancy change of the water bath. BRIEF DESCRIPTION OF THE DRAWINGS
