Description

Technical Field

[0001] The utility model relates to the technical field of distillation towers, in particular to a chemical reagent synthesis distillation tower. Background Art

[0002] Chemical reagents are chemical substances used in laboratory research and industrial production. Common chemical reagents include solutions, solids and gases, which are used for chemical analysis, reaction, synthesis and other experiments. Common reagents include acids, bases, solvents, indicators, buffers, etc. During the synthesis and processing of chemical reagents, a distillation tower is required for gas-liquid contact and separation. Patent No.: CN220002999U discloses an anti-clogging distillation tower for the synthesis of cypermethrin. The patent uses a brush to brush and clean the surface of the tower plate. However, since there are vertical plates on the tower plate, during the cleaning process, if the brush is too long and extends to the edge of the tower plate, it will be hindered by the vertical plate. If it is shorter, although it will not contact the vertical plate, the edge of the tower plate cannot be cleaned. Therefore, we introduce a chemical reagent synthesis distillation tower. Utility Model Content

[0003] The main purpose of the utility model is to provide a chemical reagent synthesis distillation tower, which can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Preferably, the cleaning assembly comprises a cylinder, a No. 2 brush plate and a spring are fixedly connected to the upper portion of the outer surface of the cylinder, a No. 3 brush plate is fixedly connected to the lower portion of the outer surface of the cylinder, the spring, the No. 3 brush plate and the No. 2 brush plate are all arc-shaped structures, the end of the spring away from the cylinder is fixedly connected to the No. 1 brush plate, and the front surface of the No. 2 brush plate is fixedly connected to a limiting piece.

[0008] Preferably, one end of the No. 2 brush plate close to the No. 1 brush plate is fixedly connected to a connecting piece No. 1, and one end of the No. 1 brush plate close to the No. 2 brush plate is fixedly connected to two No. 2 connecting pieces, and the two No. 2 connecting pieces are movably connected to the No. 1 connecting piece through a rotating shaft, and there is no contact between the spring leaf and the No. 2 brush plate, and the No. 1 brush plate is an arc-shaped structure.

[0009] Preferably, three trays are installed on the inner wall of the distillation tower body.

[0010] Preferably, the cylinder is movably connected to the tower tray, the second brush plate and the spring are both located at the upper part of the tower tray, the third brush plate is located at the lower part of the tower tray, and the spring is not in contact with the tower tray.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] By setting a driving device, it will be movably connected with the tower plate so that the No. 2 brush plate and the No. 1 brush plate are located on the upper part of the tower plate to clean the upper end of the tower plate, and the No. 3 brush plate cleans the lower end of the tower plate. As a vertical plate is provided on the tower plate, when the No. 1 brush plate contacts the vertical plate, since the No. 1 brush plate and the No. 2 brush plate are movably connected, the No. 1 brush plate will adjust its angle while contacting the vertical plate. As the motor rotates, the motor drives the cylinder to rotate continuously. After the No. 1 brush plate is no longer in contact with the vertical plate on the tower plate, it rebounds under the action of the spring sheet, thereby cleaning the edge of the upper end of the tower plate, thereby improving the cleaning efficiency.

[0024] In this embodiment, the driving device 5 includes a motor 51, a transmission rod 52 is fixedly connected to the output end of the motor 51, and three cleaning components 53 are fixedly connected to the outer surface of the transmission rod 52; the cleaning component 53 includes a cylinder 531, a second brush plate 535 and a spring 532 are fixedly connected to the upper part of the outer surface of the cylinder 531, and a third brush plate 536 is fixedly connected to the lower part of the outer surface of the cylinder 531. The spring 532, the third brush plate 536 and the second brush plate 535 are all arc-shaped structures, and the end of the spring 532 away from the cylinder 531 is fixedly connected to the first brush plate 533, and the front of the outer surface of the second brush plate 535 is fixedly connected to the limiting member 534; the second brush plate 535 One end close to the No. 1 brush plate 533 is fixedly connected to a connecting piece 537, and one end of the No. 1 brush plate 533 close to the No. 2 brush plate 535 is fixedly connected to two No. 2 connecting pieces 538. The two No. 2 connecting pieces 538 are movably connected to the No. 1 connecting piece 537 through a rotating shaft. There is no contact between the reed 532 and the No. 2 brush plate 535, and the No. 1 brush plate 533 is an arc-shaped structure; three tower plates 11 are installed on the inner wall of the distillation tower body 1; the cylinder 531 is movably connected with the tower plate 11 through the interlacing, the No. 2 brush plate 535 and the reed 532 are both located at the upper part of the tower plate 11, and the No. 3 brush plate 536 is located at the lower part of the tower plate 11, and the reed 532 is not in contact with the tower plate 11.
