chemical beaker

Abstract

The invention discloses a novel material beaker for chemical purpose. The beaker is composed of a cup body and a cup cover matching with the beaker body, the cup body comprises a beaker body, the upper end surface of the beaker body is symmetrically provided with a first water outlet nozzle and a second water outlet nozzle, and a handle that coincides with the central surface of the first water outlet nozzle and the second water outlet nozzle is welded to the sidewall of the beaker body. The first water outlet nozzle and the second water outlet nozzle are symmetrically arranged at the upper bead of the beaker body, the upper part of the first water outlet nozzle is covered with a water stopping cover connected with the sidewall of the beaker body, and the first water outlet nozzle is provided with a detachably mounted filter screen in a matching manner, so when a user uses the beaker, a liquid is poured out through the first water outlet nozzle, the liquid discharge speed is controlledby the water stopping cover, and the liquid inside the beaker can be filtered through the filter screen to avoid wastes and beaker sidewall pollution caused by liquid splashing and realize easy filtration of filter residues.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a chemical material beaker. Background technique [0002] A beaker refers to a common laboratory glassware made of glass, plastic, or heat-resistant glass. The beaker is cylindrical with a notch on one side of the top for easy pouring. Beakers are widely used for heating, dissolving, mixing, boiling, melting, evaporation concentration, dilution and precipitation clarification of chemical reagents. [0003] During the use of existing beakers, it is often necessary to transfer the solution inside. When transferring the beaker to a container with a small caliber, the experimenter must strictly control the inclination angle of the beaker, otherwise the solution in the beaker will change from The side wall of the beaker overflows, causing waste. At the same time, although the existing beaker cover can prevent the heat in the beaker from volatilizing, its sealing performan...

Problems solved by technology

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a beaker made of chemical materials. A first spout and a second spout are symmetrically arranged on the upper edge of the beaker body, and a cover is provided on the upper part of the first spout. There is a water shield connected to the side wall of the beaker body, and a detachable filter screen is provided on the first spout, so that when the user needs to control the pouring speed of the beaker during use, the liquid will be discharged through the first spout. For pouring, a filter screen can also be set on the upper part of the first spout to filter the liquid inside the beaker according to the needs. This structure is convenient for pouring the liquid, avoiding the phenomenon of waste and pollution of the side wall of the beaker caused by liquid splashing, and it is convenient to filter the filter residue. The cup body is equipped with a cup cover, and the cup cover is composed of a sealing plug, a top cover and a handle, wherein the sealing plug is provided with a chute near the position of the first spout, and a movable plug is slidably connected inside the chute. There is a water guide pipe inside the cup cover, and the water guide pipe is connected to the hose through the overflow nozzle at the end of the handle, and the end of the hose is connected to a whistle. This structure can seal the cup body to avoid heat dissipation. The heating time is shortened, the cup cover is convenient for air conduction and directional liquid discharge through the water guide pipe and hose, and the whistle is blown by the air flow to make a prompt sound. On the premise of ensuring safety, the heating time of the beaker is shortened to avoid the liquid boiling on the side wall of the beaker Occurrence of pollution; grid-like stripes are evenly opened on the inner wall of the mold. After melting the polyimide, it is evenly spread on the outer surface of the beaker body to form a polyimide protective film. This structure makes the polyimide The amine protective film can be closely combined with the glass layer of the beaker body, which can prevent the glass from breaking and causing injury to the experimenters. insulation
