Technical Field

[0001] The utility model relates to the technical field of dimethyl carbonate processing, in particular to a dimethyl carbonate dehydrator. Background Art

[0002] Dimethyl carbonate is an organic compound with the chemical formula C3H6O3. It is a low-toxic, environmentally friendly, and widely used chemical raw material. It is an important organic synthesis intermediate. Its molecular structure contains functional groups such as carbonyl, methyl, and methoxy. It has a variety of reaction properties. It is safe, convenient, less polluting, and easy to transport in production. In order to improve the purity of dimethyl carbonate, a dehydrator is used to dehydrate dimethyl carbonate.

[0003] However, the dehydrating agent in the existing dimethyl carbonate dehydrator cannot be evenly distributed in the dehydrator from top to bottom, resulting in the inability to efficiently dehydrate the dimethyl carbonate in the dehydrator. In view of the above problems, it is urgent to carry out innovative design based on the original dimethyl carbonate dehydrator. Utility Model Content

[0006] Preferably, a heating cavity is opened on the side of the shell, and electric heating rods are installed inside the heating cavity. The electric heating rods are distributed at equal angles with respect to the central axis of the shell.

[0007] Preferably, an exhaust pipe is provided on one side of the top of the shell, and the exhaust pipe is designed to be a "U"-shaped structure. A bottom cover is threadedly installed on the bottom of the exhaust pipe, and a dust filter is clamped inside the bottom cover.

[0008] Preferably, a feeding bin is provided on one side of the top of the shell body away from the exhaust pipe, and a top cover is threadedly mounted on the top of the feeding bin.

[0009] Preferably, a discharge pipe is provided at the bottom of one side of the shell, and a manual valve is installed on the discharge pipe.

[0010] Preferably, the diameter of the silica gel dehydrating agent is larger than the diameter of the water permeable hole.

[0011] Preferably, a heat insulation board is fixed to the outer wall of the shell, and the heat insulation board is designed as a hollow cylindrical structure.

[0012] Compared with the prior art, the utility model has the following beneficial effects: the dimethyl carbonate dehydrator is provided with a plate body and an inner cavity, so that the silica gel dehydrating agent can be evenly distributed from top to bottom inside the dehydrator, increasing the area of ​​the silica gel dehydrating agent absorbing the internal moisture of the dimethyl carbonate, which is beneficial to the dehydration of the dimethyl carbonate. At the same time, starting the motor can drive the silica gel dehydrating agent to rotate, so that the silica gel dehydrating agent can contact more dimethyl carbonate, further improving the efficiency of the dehydration of the dimethyl carbonate.

[0013] Under the obstruction of the plate body and the water-permeable holes, dimethyl carbonate can be separated from the silica gel dehydrating agent, so that dimethyl carbonate can be directly discharged quickly from the discharge pipe, thereby improving the rapid discharge of dimethyl carbonate after dehydration;

The high temperature inside the shell heats the silica gel dehydrating agent, so that the water inside the silica gel dehydrating agent evaporates and is discharged through the exhaust pipe, so that the silica gel dehydrating agent can be used again.

The electric heating rods 9 are distributed at equal angles with respect to the central axis of the shell 1 , which is beneficial for the dimethyl carbonate inside the shell 1 to be heated quickly.

[0024] An exhaust pipe 10 is arranged on one side of the top of the shell 1. The exhaust pipe 10 is designed as a "U"-shaped structure. A bottom cover 11 is threadedly installed on the bottom of the exhaust pipe 10. A dust filter 12 is clamped inside the bottom cover 11. The top of the dust filter 12 fits with the bottom of the exhaust pipe 10. A through hole 13 is provided at the bottom of the bottom cover 11. The dust filter 12 prevents external dust from entering the interior of the shell 1 through the exhaust pipe 10, thereby ensuring the cleanliness of the interior of the shell 1 and allowing the dust filter 12 to be removed for cleaning.

[0025] A feeding bin 14 is provided on one side of the top of the shell 1 away from the exhaust pipe 10 , and a top cover 15 is threadedly mounted on the top of the feeding bin 14 , through which dimethyl carbonate can be fed into the interior of the shell 1 .

[0029] Working principle: When using the dimethyl carbonate dehydrator, firstly, the dimethyl carbonate to be dehydrated is fed into the shell 1 through the feeding bin 14. Under the action of the plate 3 and the inner cavity 4, the silica gel dehydrating agent 6 can be evenly distributed from top to bottom in the shell 1, increasing the area of ​​the silica gel dehydrating agent 6 to absorb the water inside the dimethyl carbonate, so that the water in the dimethyl carbonate enters the inner cavity 4 through the water-permeable hole 5 and is absorbed by the silica gel dehydrating agent 6 inside the inner cavity 4. By starting the motor 7, the rotating shaft 2, the plate 3 and the silica gel dehydrating agent 6 inside the plate 3 can be driven to rotate, so that the silica gel dehydrating agent 6 can absorb more water in the dimethyl carbonate;

Then the electric heating rod 9 is started to heat the inside of the shell 1, so that the temperature inside the shell 1 increases. The high temperature inside the shell 1 heats the silica gel dehydrating agent 6, so that the water inside the silica gel dehydrating agent 6 evaporates and is discharged through the exhaust pipe 10, so that the silica gel dehydrating agent 6 can be used again.
