Abstract
Description
Technical Field
[0001] This utility model relates to the field of dimethyl carbonate production technology, specifically to a dimethyl carbonate production device capable of continuous feeding. Background Technology
[0002] Dimethyl carbonate is a green and environmentally friendly organic compound with the chemical formula C3H6O32. Its molecular structure contains active groups such as carbonyl, methyl, and methoxy groups, exhibiting both excellent reactivity and low toxicity. At room temperature, it is a colorless and transparent liquid with a density of 1.069 g / cm³, a melting point of 4℃, a boiling point of 90℃28, a slightly sweet taste, and is slightly soluble in water.
[0003] Current dimethyl carbonate production facilities still require manual feeding, which results in low feeding efficiency. Furthermore, the slow feeding speed leads to insufficient processing time for the raw materials, reduced quality, and decreased economic benefits for the enterprise. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] To address the shortcomings of existing technologies, this invention provides a dimethyl carbonate production apparatus capable of continuous feeding, thereby solving the problems mentioned in the background section.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a dimethyl carbonate production device capable of continuous feeding, wherein a conveying pipe is fixedly installed on the bottom surface of the feed hopper, a gear is fixedly installed on the inner side of the conveying pipe, a conveyor belt is meshed with the outer side of the gear, a hopper is fixedly installed on the side of the conveyor belt, a discharge hopper is fixedly installed on the bottom surface of the conveying pipe, a heavy component separation device is fixedly installed on the bottom surface of the discharge hopper, a connecting pipe is fixedly installed on the right side of the heavy component separation device, a distillation device is fixedly installed on the section of the connecting pipe away from the heavy component separation device, a distillation tube is fixedly installed on the top surface of the distillation device, a distillation connecting pipe is fixedly installed at the top end of the distillation tube, a first distillation flask is fixedly installed on the end of the distillation connecting pipe away from the distillation tube, a second distillation flask is fixedly installed on the right side of the first distillation flask, a recovery tank is fixedly installed on the right side of the second distillation flask, a booster pump is fixedly installed on the top surface of the recovery tank, and a recovery pipe is fixedly installed on the top surface of the booster pump.
[0008] Preferably, the top surface of the conveying pipe has a feed inlet, the bottom surface of the conveying pipe has a discharge outlet, and a fixing rod is fixedly installed on the inner side of the conveying pipe.
[0009] Preferably, the transmission track includes side blocks, and a connecting rod is fixedly installed between the two side blocks.
[0010] Preferably, the hoppers are arranged at fixed intervals, comprising a plurality of hoppers.
[0011] Preferably, the first distillation flask and the second distillation flask are connected by a distillation connecting tube.
[0012] Preferably, the heavy component separation device is connected to the interior of the distillation apparatus via a connecting pipe.
[0013] Compared with the prior art, this utility model provides a dimethyl carbonate production device that can continuously feed materials, which has the following beneficial effects:
[0014] 1. This continuously fed dimethyl carbonate production device first feeds the raw material into the conveying pipe through the feed hopper. In the conveying pipe, the raw material falls into the hopper. The hopper is driven by gears through a conveyor belt to transport the raw material. Compared with ordinary conveying devices, the conveyor belt is more adaptable to bending and lifting operations, has a longer service life, and allows for the replacement and maintenance of individual parts, resulting in lower maintenance costs. The hopper can transport not only solid raw materials but also liquid raw materials, making it suitable for a wider range of applications. When the hopper reaches the upper side of the discharge hopper, the side of the hopper contacts the fixed rod. The fixed rod obstructs the movement of the hopper, causing it to tilt and tip when it contacts the surface of the fixed rod, allowing the raw material to enter the heavy component separation device.
[0015] 2. This continuously fed dimethyl carbonate production unit, after the raw material is separated, will enter the distillation unit for distillation. The distilled raw material can enter the distillation flask for second distillation to achieve better distillation quality and distillation purpose, thereby purifying the raw material and improving product quality. After distillation, the purified raw material will enter the recovery tank for unified recovery, and then enter the recovery pipe through the booster pump. At this time, the processed raw material can be taken out. Attached Figure Description

A distillation flask 2 12 is fixedly installed on the right side of the distillation flask 11. A recovery tank 14 is fixedly installed on the right side of the distillation flask 2 12. A booster pump 15 is fixedly installed on the top surface of the recovery tank 14. A recovery tube 16 is fixedly installed on the top surface of the booster pump 15.
[0022] Furthermore, the top surface of the conveying pipe 2 is provided with an inlet 201, the bottom surface of the conveying pipe 2 is provided with an outlet 202, and a fixing rod 203 is fixedly installed on the inner side of the conveying pipe 2.
[0023] Through the above technical solution, the fixing rod 203 can move the hopper 5, causing the hopper 5 to tilt and dump the raw materials inside the hopper 5.
[0024] Furthermore, the transmission track 3 includes side blocks 301, and a connecting rod 302 is fixedly installed between the two side blocks 301.
[0025] Through the above technical solution, the transmission track 3 is more adaptable to bending and lifting operations than ordinary transmission devices, has a longer service life, and allows for the replacement and repair of individual components, resulting in lower maintenance costs in the later stages.
[0026] Furthermore, there are several hoppers 5 arranged at fixed intervals.
[0027] Through the above technical solutions, the hopper 5 can not only transport solid raw materials, but also liquid raw materials, thus having more and wider application scenarios.
