Description

Constant temperature water bath device

Technical Field

The utility model relates to a water bath with thermostatic control equipment field, concretely relates to water bath with thermostatic control device.

Background

The constant temperature water bath device is mainly used for distilling, drying, concentrating and warm-soaking chemical drugs or biological products in a laboratory, can also be used for constant temperature heating and other temperature tests, and is a necessary tool for biology, heredity, viruses, aquatic products, environmental protection, medicine, sanitation, laboratories, analysis rooms and educational and scientific research. Due to the particularity of biological products, the characteristics of proteins and the influence of process parameters such as temperature, pH, conductance and the like on products need to be fully considered, so the accuracy and uniformity of temperature process parameter control are particularly important.

However, although the temperature of the existing thermostatic water bath device can be controlled to be +/-0.5 ℃, the problems of accuracy and uniformity of the temperature in the sample container still cannot be effectively solved, and the requirements of pharmaceutical enterprises on CGMP production cannot be met. It is known that when the sample container is light in weight or the sample solution is small in amount, the sample container may be floated, inclined or even turned over, thereby seriously affecting the temperature uniformity of the sample container and the accuracy of the temperature detection data. In order to overcome the problem that the buoyancy of a water bath device causes instability of a sample container, the prior art CN106283665A discloses a water bath device for a cotton knitted fabric dyeing and finishing method, which specifically comprises that clamping plates with spring telescopic rods are respectively arranged at the middle parts of two opposite sides of the inner side of the water bath device and the middle part of the bottom of the water bath device for fixing the sample container, and the sample container can be fixed when the area of the clamping plates is larger and the clamping force is larger. This prior art has the following disadvantages: (1) the sample container temperature is not uniform. Because the clamping plate is in close contact with the outer wall of the sample container in a large area, the sample in the sample container, which is easily in the contact part of the clamping plate and the sample container, cannot be timely and fully subjected to heat exchange with the outside in the heat preservation process, and the temperature in the sample container is easily uneven. (2) The water circulation in the water bath device cannot be realized in the process of heat preservation by adopting an external circulation heating mode, so that the water temperature of the upper layer is higher than that of the bottom layer, and the heat exchange speed of the sample in the sample container is uneven, so that the temperature in the sample container is uneven. (3) The clamping plates are easily damaged, require frequent downtime for replacement, and can also wear the outer wall of the sample container. When the sample container is placed or pulled out, the clamping plates are easy to generate plastic deformation, so that the clamping device is damaged, the sample container cannot be clamped effectively, the clamping plates need to be replaced frequently in the actual large-scale production process, and the outer wall of the sample container is also seriously abraded, so that the sample leakage is easy to cause.

The prior art CN206762919U discloses a constant temperature water bath with a fixing device, which specifically comprises a pot body, wherein the bottom of the pot body is provided with a container fixing device for fixing a container for fixing articles to be constant temperature; the fixing device comprises a fixing seat and a clamp, and the fixing seat is fixedly arranged at the bottom of the pot body; the clamp comprises a first clamp and a second clamp, the first clamp and the second clamp are of symmetrically arranged semicircular structures, and the outer contours of the first clamp and the second clamp are combined to form a whole non-dislocation circle; the two ends of the first clamp and the second clamp are respectively provided with an insert, the clamps are arranged on corresponding fixed seats through the inserts, and the inserts on the first clamp are slidably arranged on the fixed seats; the utility model discloses a pot body, including pot body, mounting panel, adjusting nut and screw rod, anchor clamps open and shut mechanism is installed in the first anchor clamps outside, anchor clamps open and shut mechanism includes mounting panel, adjusting nut and screw rod, the mounting panel is fixed to be set up pot body bottom, the screw rod passes the mounting panel links to each other with the first anchor clamps outside, can realize through rotatory adjusting nut pulling first anchor clamps that anchor clamps open and shut. In order to solve the problem of abrasion of the clamp to the sample container, the prior art uses a clamp made of plastic, and a rubber gasket is added on the inner side of the clamp. Although the prior art solves the problem of abrasion of the clamp to the sample container to a certain extent, the used plastic clamp and the rubber gasket thereof are more easily attached to the outer wall of the sample container more tightly, so that the heat exchange efficiency between the sample in the area and hot water is lower, the temperature difference in the sample container is more obvious, and even the quality of the sample is possibly deteriorated.

Prior art CN208390058U discloses a digital display constant temperature water bath, its concrete structure is: the water bath bottom is equipped with spiral disk's heating pipe, and the heating pipe extends to circle around the water bath and go up, and heating pipe and water bath in close contact with, and the heating pipe wraps up the setting completely around the water bath, can heat the water bath by the high efficiency, and heat distribution is even moreover, has guaranteed the accuracy nature that detects. Although the problem of uniform heat distribution of the water bath is solved in the prior art, the problem of buoyancy of the water bath is not effectively solved, and the technical problem that a sample container is easily abraded by the water bath is not effectively solved.

Therefore, there is a need to design a thermostatic water bath device which is simple and highly operable and can effectively solve the above problems.
