Technical Field

[0001] The utility model belongs to the field of experimental instruments, in particular to a reagent heater. Background Art

[0002] In chemical experiments, heating reagents is one of the common operating steps. Heating can speed up the reaction rate, dissolve solid reagents, remove solvents from solutions, and change the properties of reagents.

[0003] Existing reagent heating is mostly done by heating a beaker with an alcohol lamp, and then placing the test tube into the beaker for heating. The test tube needs to be manually clamped for operation, which may cause the test tube to break and endanger the safety of the experimenter. Some test tubes are placed on a test tube rack for fixing during heating, but when placing test tubes of different specifications, racks with different apertures need to be replaced, which is inconvenient to operate and has poor practicality. Utility Model Content

[0006] Furthermore, sliding grooves are provided on the left and right sides of the limiting hole, and sliding blocks are fixedly provided on both sides of the clamping plate, and the sliding blocks are slidably connected to the sliding grooves.

[0007] Furthermore, a shift block is fixedly provided on the upper portion of the splint, and the shift block is configured as a slope-shaped structure.

[0008] Furthermore, the heating chamber is configured as a hollow box structure, and a drain port is provided at the lower portion of the heating chamber.

[0012] 1. The reagent heater proposed in this scheme is connected between the lifting plate and the heating chamber by a hydraulic cylinder. The test tube containing the reagent can be taken out from the heating chamber without manual contact with the test tube, which is easy to operate and has high safety.

[0013] 2. The reagent heater proposed in this scheme can limit and fix test tubes of different sizes under the clamping control of springs and clamps by arranging a clamping and fixing mechanism on the lifting plate, and has high practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1 and Figure 2As shown, a reagent heater proposed by the utility model includes a heating bin 1, a hydraulic cylinder 2 and a clamping and fixing mechanism 4, wherein the lower end of the hydraulic cylinder 2 is fixedly connected to the rear side of the heating bin 1, and a lifting plate 3 is fixedly arranged on the upper end of the hydraulic cylinder 2, and the clamping and fixing mechanism 4 is arranged on the upper part of the lifting plate 3, and the clamping and fixing mechanism 4 includes a spring 405 and a clamping plate 406, and a plurality of groups of limiting holes 401 are arranged on the upper part of the lifting plate 3, and one end of the spring 405 is connected to the limiting hole 401, and the other end of the spring 405 is connected to the clamping plate 406 is connected, the splint 406 is slidably connected to the limiting hole 401, and sliding grooves 403 are provided on the left and right sides of the limiting hole 401. Slide blocks 402 are fixed on both sides of the splint 406, and the slide blocks 402 and the sliding grooves 403 are slidably connected to limit the position and moving direction of the splint 406. A shift block 404 is fixed on the upper part of the splint 406, and the shift block 404 is set as a ramp-shaped structure, which is used to shift and squeeze the splint 406 to facilitate the insertion of the test tube between the limiting hole 401 and the splint 406.

[0021] like Figure 1 and Figure 3 As shown, the heating chamber 1 is configured as a hollow box structure, a drain port 101 is provided at the lower portion of the heating chamber 1 for containing and discharging heated water, a plurality of connecting holes 102 are provided at the upper portion of the heating chamber 1, the connecting holes 102 and the limiting holes 401 are located on the same axis, a plurality of heating rods 103 are provided inside the heating chamber 1, and the heating chamber 1 is made of thermal insulation material.

[0022] During specific use, heating water is added to the heating chamber 1 through the connecting hole 102, and the heating rod 103 is used to heat the water in the heating chamber 1. The pressing block 404 and the spring 405 drive the clamping plate 406 to slide, and the test tube containing the reagent to be heated is inserted between the limiting hole 401 and the clamping plate 406. Under the rebound action of the spring 405, the clamping plate 406 presses the test tube to complete the limited clamping of the test tube, and can clamp test tubes of different specifications. It is highly practical. At the same time, the hydraulic cylinder 2 is shortened to drive the lifting plate 3 and the test tube clamped by the clamping fixing mechanism 4 to move downward, and is inserted into the heating chamber 1 from the connecting hole 102 to complete the heating of the reagent. After the heating reaction is completed, the hydraulic cylinder 2 is controlled to extend. Driven by the hydraulic cylinder 2, the test tube is pulled out of the heating chamber 1. After the test tube is cooled, the pressing block 404 is repeated to remove the test tube. There is no need to directly remove the test tube from the heating device. The operation is convenient and the safety is high.
