Description

Technical Field

[0001] The utility model relates to a water bath pot, in particular to a constant temperature water bath pot for chemical processing. Background Art

[0002] Constant temperature water baths are widely used in drying, concentration, distillation, impregnation of chemical reagents, impregnation of drugs and biological preparations. They can also be used for constant temperature heating of water baths and other temperature tests. They are essential tools for education and scientific research in biology, genetics, virus, aquaculture, environmental protection, medicine, health, biochemical laboratories, and analysis rooms.

[0003] For example, a constant temperature water bath for chemical processing is disclosed in a Chinese patent with the publication number CN218872261U.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 The utility model provides a technical solution: a constant temperature water bath for chemical processing, comprising a heating seat 1, a water bath 2 placed on the heating seat 1, a heat preservation and heating chamber 101 opened in the heating seat 1, circulation pipes 104 fixedly connected on both sides of the heat preservation and heating chamber 101, connectors 201 fixedly connected on both sides of the water bath 2, the other end of the circulation pipe 104 fixedly connected to the connector 201, a pump 103 fixedly connected in the heat preservation and heating chamber 101, the output end of the circulation pipe 104 fixedly connected to a circulation pipe 104, a step frame 3 placed in the water bath 2, a filter hole 301 opened on the step frame 3, and a sealing cover 4 threadedly mounted on the upper end of the water bath 2.

[0021] In this embodiment, by placing the step rack 3 inside the water bath 2, the filter hole 301 can allow clean water to pass through smoothly. The step rack 3 is stepped as a whole, and different steps have different heights. Water bath vessels can be placed on the step rack 3. According to the height of the water bath vessels, they can be placed on the appropriate steps, so that water bath vessels of various specifications can be placed at one time. At the same time, the ends of the water bath vessels can be kept above the clean water, while most of the main bodies of the water bath vessels are immersed in the clean water for heating. The heat preservation and heating chamber 101 can accommodate a certain amount of clean water. When the water bath vessels are heated, the pump 103 is started to pump the clean water inside the heat preservation and heating chamber 101 through the circulation pipe 104 to the water bath 2. The interior of the water bath 2 is closed as a whole, and the clean water will be squeezed into the heat preservation and heating chamber 101 from the circulation pipe 104 on the other side, so that the clean water inside the water bath 2 is continuously circulated, thereby making the clean water temperature at each position the same.

[0022] Among them, in order to achieve the purpose of adjusting the position of the step frame 3, the present device adopts the following technical solutions: a heating tube 102 is fixedly connected to the heat preservation and heating chamber 101, and a limiting groove 202 is provided on the inner walls of both sides of the water bath 2. A first threaded sleeve 303 is symmetrically fixedly connected to the step frame 3, and a second threaded column 304 is installed with a thread on the inner thread of the first threaded sleeve 303. A overlapping cross frame 306 is rotatably installed on the two second threaded columns 304. The overlapping cross frame 306 cooperates with the limiting groove 202. A knob 305 is fixedly connected to the upper end of the second threaded column 304, and support legs 302 are symmetrically fixedly connected to the bottom of the step frame 3.

[0023] By starting the heating tube 102, the circulating clean water in the heat-insulating heating chamber 101 can be heated to a suitable temperature, thereby maintaining the clean water inside the water bath 2 at a suitable temperature. The heat-insulating heating chamber 101 and the circulation tube 104 are both made of heat-insulating materials to prevent excessive heat loss during the circulation of the clean water. The second threaded column 304 and the first threaded sleeve 303 form a retractable connecting rod. The rotating knob 305 drives the second threaded column 304 to rotate, and the overall length of the connecting rod can be adjusted. The overlapping cross frame 306 cooperates with the limiting groove 202 to clamp the overlapping cross frame 306 inside the water bath 2. The overlapping cross frame 306 is connected to the step frame 3 through the connecting rod, thereby supporting the step frame 3 to be suspended inside the water bath 2. By adjusting the length of the connecting rod, the depth of the step frame 3 inside the water bath 2 can be adjusted.

[0024] Among them, in order to achieve the purpose of filtering harmful gases inside the water bath 2, the present device adopts the following technical solutions: a one-way valve 402 is fixedly connected to the sealing cover 4 near the edge of one side, a handle 401 is fixedly connected to the center of the sealing cover 4, and a suction filtering mechanism 403 is fixedly connected to the sealing cover 4 near the edge of the other side.

[0025] The one-way valve 402 allows outside air to enter the water bath 2, and the suction and filtering mechanism 403 can be used to suck and filter the critical gases generated inside the water bath 2. This is an existing structure, and no further details will be given. It prevents harmful gases generated by the water bath 2 heating chemicals from being retained inside the water bath 2. The handle 401 prevents the operator from removing the sealing cover 4.

[0026] The working principle and usage process of the present invention are as follows: when using, the device needs to be placed in a suitable position. According to the height specification of the water bath vessel, the knob 305 is rotated to drive the second threaded column 304 to rotate, and then the depth of the step rack 3 inside the water bath pot 2 is adjusted. After the step rack 3 is adjusted to the appropriate depth, the water bath vessels are placed at different positions on the step rack 3 to ensure that the end of each water bath vessel is on the water surface and most of it is submerged in clean water. The sealing cover 4 can be closed to seal the inside of the water bath pot 2, and the heating tube 102 is started to heat the clean water inside the heat preservation and heating chamber 101. At the same time, the pump 103 is started to drive the clean water to circulate between the heat preservation and heating chamber 101 and the water bath pot 2, so that the hot water can circulate into the water bath pot 2, thereby heating the water bath vessels.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
