Description

Technical Field

[0001] This utility model relates to the field of cooling device technology, specifically to a rapid cooling device for laboratory containers. Background Technology

[0002] In chemical titration experiments and sample pretreatment, it is often necessary to heat the reagents or solutions in the container: in titration experiments, the reagents in the conical flask must be heated first to achieve a color reaction, and the subsequent titration can be carried out after cooling; in sample pretreatment, the solution in the beaker must also be heated to dissolve the sample, and the subsequent steps such as filtration and volume adjustment can only be carried out after cooling.

[0003] Current mainstream laboratory cooling methods have significant shortcomings: Cooling by rinsing with tap water: This method cools down the conical flask or beaker by directly rinsing the outer wall of the flask, but it is time-consuming and wastes a lot of water. Water bath cooling: Placing the conical flasks and beakers to be cooled in a water-filled container allows for the simultaneous processing of multiple containers, but it can easily lead to disorganization. If the liquid level in the container is too high, the buoyancy will cause the conical flasks and beakers to become unstable and easily tip over; if the liquid level is too low, the cooling efficiency will be significantly reduced, failing to meet the requirements of the experimental schedule. Utility Model Content

[0004] The purpose of this invention is to provide a rapid cooling device for laboratory containers.

[0005] This utility model is implemented by the following technical solution: a laboratory container rapid cooling device, which includes a box body, and the interior of the box body is fixedly connected from bottom to top to a water chamber, a heating chamber, and a cooling chamber. The water chamber is used to contain the cooling substrate, and a refrigeration device is fixed inside the water chamber; A horizontally arranged electric heating plate is fixed inside the heating chamber; The cooling chamber is equipped with a support plate, and the surface of the support plate has multiple mounting holes. A support mesh is fixed to the bottom of each mounting hole. A lifting device is connected between the top end face of the support plate and the top inner wall of the cooling chamber. The water chamber is equipped with a water pump. The outlet of the water pump is connected to the interior of the cooling chamber through an inlet pipe, and the outlet of the cooling chamber is connected to the interior of the water chamber through an outlet pipe.

[0006] Furthermore, the refrigeration device includes a container and an ice pack. The container is fixedly connected to one inner wall of the water chamber. The side wall of the water chamber has a door that communicates with the interior of the container. The ice pack is installed inside the container. Furthermore, the lifting device includes a fixed frame and a telescopic device. A horizontally arranged fixed frame is fixed to the inner wall of the top of the cooling chamber, and the telescopic device is fixed to the top of the fixed frame. The telescopic end of the telescopic device passes through the fixed frame and is fixedly connected to the top end face of the support plate.

[0007] Furthermore, the heating chamber is also provided with a heat insulation plate, which is fixedly connected to the inner wall of the heating chamber and is placed between the electric heating plate and the water chamber.

[0008] The advantages of this utility model are: by setting a support plate with multiple mounting ports, the conical flask can be stably placed in the mounting port; under the action of the support net, the problem of unstable container placement during the cooling process is solved. The cooling system inside the water chamber includes ice packs, ensuring the circulating water remains at a consistently low temperature and reducing water consumption. The circulating water system, formed by a water pump, inlet pipe, and outlet pipe, solves the water waste problem associated with using running tap water for cooling. The circulating water is used to cool the conical flasks in the cooling chamber. The electric heating plate and insulation plate in the heating chamber are designed to meet the heating requirements of the containers, achieving integrated heating and cooling operations and improving experimental efficiency.

[0009] The combination of the support plate and the lifting device allows for adjustment of the immersion depth in cooling water for containers of different heights, improving cooling efficiency. Simultaneously, the lifting device facilitates subsequent filtration and volume adjustment operations. The overall design meets the diverse experimental needs of the laboratory and enhances experimental efficiency. Attached Figure Description

[0012] 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.

[0013] like Figure 1 As shown, the laboratory container rapid cooling device includes a housing 1, and inside the housing 1, a water chamber 1.1, a heating chamber 1.2, and a cooling chamber 1.3 are fixedly connected from bottom to top.

[0014] Water chamber 1.1 is used to contain the cooling substrate, and a refrigeration device 2 is fixed inside water chamber 1.1. The refrigeration device 2 includes a receiving box 2.1 and ice packs 2.2. The receiving box 2.1 is fixedly connected to one inner wall of water chamber 1.1, and a door 2.3 communicating with the inside of the receiving box 2.1 is opened on the side wall of water chamber 1.1. Ice packs 2.2 are installed inside the receiving box 2.1. The refrigeration device 2 cools the cooling substrate in water chamber 1.1 through the ice packs 2.2, thereby reducing the temperature of the cooling substrate and enhancing the cooling effect. The door 2.3 facilitates the replacement of ice packs.

[0015] A horizontally positioned electric heating plate 3 is fixed inside the heating chamber 1.2. An insulation plate 4 is also installed inside the heating chamber 1.2, fixedly connected to the inner wall of the heating chamber 1.2, and positioned between the electric heating plate 3 and the water chamber 1.1. The electric heating plate 3 is used to heat the container to achieve the colorimetric reaction. The insulation plate 4 effectively prevents the heat generated in the heating chamber 1.2 from being transferred downwards to the water chamber 1.1, preventing the cooling substrate in the water chamber 1.1 from being heated and ensuring the stability of the cooling effect.

[0016] The cooling chamber 1.3 is equipped with a support plate 5. Multiple mounting openings 6 are provided on the surface of the support plate 5, and a support mesh 7 is fixed to the bottom of each mounting opening 6. The support mesh 7 securely supports conical flasks or beakers placed within the mounting openings 6, preventing the experimental containers from slipping. A lifting device 8 connects the top end face of the support plate 5 to the inner top wall of the cooling chamber 1.3. The lifting device 8 includes a fixed frame 8.1 and a telescopic device 8.2. The fixed frame 8.1 is horizontally positioned and fixed to the inner top wall of the cooling chamber 1.3. The telescopic device 8.2 is fixed to the top of the fixed frame 8.1, and its telescopic end passes through the fixed frame 8.1 and is fixedly connected to the top end face of the support plate 5. The lifting device 8 can adjust the height of the support plate 5, allowing conical flasks or beakers of different heights to be appropriately immersed in the cooling substrate for cooling, improving the applicability of the device. The support plate 5 can also be raised to facilitate subsequent titration operations after the containers have cooled.

[0017] A water pump 9 is installed inside the water chamber 1.1. The outlet of the water pump 9 is connected to the interior of the cooling chamber 1.3 via an inlet pipe 10, and the outlet of the cooling chamber 1.3 is connected to the interior of the water chamber 1.1 via an outlet pipe 11. The water pump 9 transports the cooling substrate from the water chamber 1.1 to the cooling chamber 1.3 through the inlet pipe 10. After cooling the placed conical flask or beaker in the cooling chamber 1.3, the cooling substrate flows back to the water chamber 1.1 through the outlet pipe 11, forming a circulating cooling system. This circulating design allows the cooling substrate to flow continuously, improving heat exchange efficiency and accelerating the cooling rate.

[0018] In use, first place the conical flask or beaker to be cooled into the mounting opening 6 of the support plate 5. Adjust the height of the support plate 5 using the telescopic device 8.2 so that the bottom of the conical flask or beaker is appropriately immersed in the cooling substrate. Then, start the water pump 9 to circulate the cooling substrate between the water chamber 1.1 and the cooling chamber 1.3, rapidly cooling the conical flask or beaker. Simultaneously, the ice packs 2.2 in the refrigeration device 2 continuously cool the circulating cooling substrate, maintaining its low temperature and improving cooling efficiency.

[0019] In some cases, it may be necessary to heat the conical flask or beaker first. In this case, no cooling medium is added to the cooling chamber 1.3. The experimental container is placed in the cooling chamber 1.3, and the lifting device is lowered to its lowest position so that the container is in contact with the electric heating plate 3. Then, the electric heating plate 3 is turned on for heating. After heating, the corresponding colorimetric reaction is carried out. The electric heating plate 3 is then turned off. Before proceeding with subsequent operations, the container is cooled down first. During cooling, the water pump 9 is turned on to use the cooling medium to cool the container in the cooling chamber 1.3. After cooling, subsequent steps such as titration, filtration, and volume adjustment are performed. This achieves integrated heating and cooling operations, improving experimental efficiency.

[0020] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
