Embodiment 1

[0017] Such as Figure 1~3 As shown, a conical flask cooling pool includes a box body 1 with cooling water, the box body 1 is circular, and the water level of the cooling water is generally not more than 5 cm. A sleeve 2 is installed in the center of the box body 1, and a set of rod 3 is arranged inside the sleeve 2, and the inner surface of the sleeve 2 and the outer surface of the sleeve rod 3 are provided with threads so that the sleeve rod 3 can rotate in the sleeve 2 Perform lifting motion. The height of the sleeve 2 is 20 to 30 centimeters, and the length of the threaded portion of the sleeve rod 3 is consistent with the height of the sleeve 2 . The top of the sleeve rod 3 is provided with a driving rod 7 .

[0018] A tray 4 is fixed on the sleeve rod 3, the tray 4 includes a raised portion 41 in the middle and a flat portion 42 positioned at the periphery, the bottom of the raised portion 41 is hollow, and the diameter of the bottom of the raised portion 41 is 5 to 10...

Abstract

The invention belongs to the technical field of experimental equipment, and in particular relates to a conical flask cooling pool. This Erlenmeyer flask cooling pond comprises the box body (1) that cooling water is housed, and a sleeve (2) is housed on the described box body (1), is provided with a cover rod (3) in the sleeve (2), sleeve ( Both the inner surface of 2) and the outer surface of the sleeve rod (3) are threaded so that the sleeve rod (3) can rotate in the sleeve (2) for lifting movement, and a pallet (4) is fixed on the sleeve rod (3) , the tray (4) is provided with a plurality of grille monomers (6) for accommodating the Erlenmeyer flasks (5). The invention has the advantages of simple structure, stable operation and obvious effect. It can not only avoid the mutual collision between conical flasks, but also greatly shorten the cooling time of the reagents in the conical flasks and speed up the experiment process.

Description

technical field [0001] The invention belongs to the technical field of experimental equipment, and in particular relates to a conical flask cooling pool. Background technique [0002] In analytical chemistry experiments, it is sometimes necessary to heat the reagents in the Erlenmeyer flask, and then titrate after cooling down. The laboratory generally uses tap water to wash the outer wall of the Erlenmeyer flask for cooling, and the tap water is seriously wasted. When students experiment, because there are many Erlenmeyer flasks that need to be cooled, they often use a basin filled with water for cooling. However, due to the effect of buoyancy, the Erlenmeyer flasks are unstable and easy to overturn in the basin. The invention with the application number 201420127255.X discloses a conical flask cooling pool, which includes a tray, a strip-shaped mounting plate is fixedly connected to the periphery of the tray, and a support rod is fixedly arranged on the mounting plate. On...
