Embodiment 1

[0042] The method for brushing the bottom of the three-necked flask and the attachments on the bottle mouth of the present invention comprises the following steps:

[0043] S1, the air bag 3 is not inflated, it is in a folded state, and then it is inserted into the bottle body of the three-necked bottle through the middle bottleneck of the three-necked bottle 16;

[0044] S2. Insert the bottom end of the straight pipe 2 into the three-necked bottle 16 through the middle mouth of the three-necked bottle 16 until the bottom of the positioning ring 18 contacts the top end face of the middle neck, and the inner wall of the stop ring 19 and the outer wall of the middle neck The upper side fits, such as Figure 4 shown;

[0045] S3, then start the system for supplying pressure gas, so as to inflate the inside of the airbag 3 through the flexible pipe 1 and the straight pipe 2; with the inflation, the airbag 3 is stretched out, the inferior spherical shell in the airbag 3 coincides wi...

Embodiment 2

[0056] This embodiment is on the basis of embodiment 1 to further illustrate the cleaning of the present invention.

[0057] Such as figure 1 As shown, there are two airbags 3, namely an upper airbag and a lower airbag, and they are symmetrically distributed up and down, and their centers of spheres coincide with each other, and the convex surface of the inferior spherical shell A9 of the upper airbag is fixed on the bottom of the straight pipe 2 , which communicates with the inner hole of the straight pipe 2 through the upper through hole 12 arranged on the inferior spherical shell A9;

[0058] A connecting pipe 13 coaxial with the straight pipe 2 is arranged between the upper airbag and the lower airbag. The upper and lower ends of the connecting pipe 13 are respectively connected to the concave surface of a bad spherical shell B7. The lower end of the connecting pipe 13 is set by The bottom through hole 11 on the inferior spherical shell B7 of the lower air bag communicate...

Embodiment 3

[0062] This embodiment is based on Embodiment 2 to further illustrate the present invention.

[0063] Such as figure 1 and figure 2 As shown, in the present invention, the air bag 3 is connected to the end of the connecting pipe 13 through a connecting assembly, the connecting assembly includes a hard pipe 14 and a sealing ring 15, and an annular groove 17 is provided at the end of the inner wall of the straight pipe 2 , the outer ring of the sealing ring 15 is installed in the annular groove 17, and the inferior spherical shell B7 protrudes toward the center of the ball along the circumference of the bottom through hole 11 to form a connecting neck 16, and the connecting neck 16 is One end close to the center of the ball is connected to one end of a hard tube 14 , and the other end of the hard tube 14 is inserted into the inner hole of the sealing ring 15 and is interference-fitted with the sealing ring 15 .

[0064] Preferably, the outer peripheral surface of the hard pip...

Abstract

The invention discloses a method for brushing off attachments at the flask bottom and flask openings of a three-neck flask. The method comprises the following steps that an air bag is stuffed into a flask body of the three-neck flask until a positioning ring is in contact with the top end of a middle flask opening and the inner wall of a limiting ring is attached to the outer wall of the middle flask opening; the interior of the air bag is inflated through a hose and a straight pipe, an inferior spherical shell in the air bag coincides with the sphere center of the flask body along with inflation, and bristles make contact with the whole bottom of the inner wall of the flask body; and the straight pipe is repeatedly rotated around an axis of the straight pipe relative to the three-neck flask, so that the attachments on the whole bottom of the inner wall of the flask body are brushed off. According to the method for brushing off the attachments at the flask bottom and the flask openingsof the three-neck flask, the attachments at the bottom of the inner wall are brushed off through a deformable cleaning device so as to clean the bottom of the inner wall in a unified mode, and the problems that when cleaning is carried out on the bottom of an existing three-neck flask, due to the limitation of the radial size of flask openings and the length of the flask neck, the cleaning rangeof the bottom is limited, cleaning can not be carried out on the whole flask bottom bearing a solution, and the cleaning effect is poor are effectively solved. Cleaning effect is poor.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for removing attachments on the bottom and mouth of a three-necked flask by brushing. Background technique [0002] The three-necked flask is a chemical instrument, also known as the three-necked flask, the three-necked flask, and the three-necked round-bottomed flask. [0003] The three-necked bottle usually has a round belly and a narrow neck. It has a spherical bottle body and three ports connected to the bottle body and communicated with the inner cavity of the bottle. Multiple reactants can be added at the same time, or a condenser tube can be added. Its narrow mouth is used to prevent the solution from splashing or reduce the evaporation of the solution, and it can be used with rubber stoppers to connect other glass equipment. When the solution needs to react for a long time or be heated to reflux, a three-necked bottle is generally selected as the conta...
