Description
Technical Field
The utility model relates to an organic chemical product epoxy fatty acid methyl ester apparatus for producing, concretely relates to epoxy fatty acid methyl ester reation kettle sampling device.
Background
At present, sampling operation of epoxy fatty acid methyl ester reaction generally adopts sampling from a discharge outlet at the bottom of a closed reaction kettle, and the existing defects are as follows: because the valve is arranged at the discharge port, the original material is retained at the valve, the sample is not representative, the product quality can not be truly reflected often, and the quality hidden danger is left for the product quality; if a discharging valve at the bottom of the reaction kettle is opened, the retained materials before reaction are replaced by the reacted materials and then sampled, although the defect that the samples obtained by the former are not representative can be overcome, a large amount of reaction materials can be wasted by the sampling mode, and the yield of the epoxy fatty acid methyl ester is influenced.
Disclosure of Invention
The utility model aims at providing a simple structure, preparation and maintenance cost are low, convenient operation is high-efficient, the sample of taking is representative and can avoid extravagant epoxy fatty acid methyl ester reation kettle sampling device of reaction back material.
In order to realize the purpose, the sampling device of the epoxy fatty acid methyl ester reaction kettle comprises a glass sampling tank, a buffer tank and a vacuum pump; the upper inlet of the glass sampling tank is connected with a copper pipe, the other end of the copper pipe extends into the middle of the reaction kettle, and the bottom of the glass sampling tank is provided with a material outlet valve; an upper inlet of the buffer tank is connected with an upper outlet of the glass sampling tank through a copper pipe, and the bottom of the buffer tank is provided with an air breaking valve; and the vacuum pump is connected with an upper outlet of the buffer tank through a copper pipe.
When the sample is taken, the material outlet valve and the air breaking valve are closed firstly, the vacuum pump is opened, the vacuum pump is closed when the sample reaches a certain amount by observing the glass sampling tank, the air breaking valve is opened to break air, and the material outlet valve is opened after the air breaking to take a sample.
The epoxy fatty acid methyl ester reaction kettle sampling device with the structure has the following technical characteristics and beneficial effects: firstly, the sample can be taken from the middle part of the reaction kettle, and the taken sample is representative, so that hidden danger on the quality of the product is avoided; secondly, the problem of material waste after reaction caused by sampling by replacing the original material in the prior art is avoided, so that the yield is increased; thirdly, the utility model discloses each part simple manufacture, the cost of manufacture is low, and is easy and simple to handle during production, easy popularization.
Drawings
FIG. 1 is a schematic structural diagram of the sampling device of the epoxy fatty acid methyl ester reaction kettle of the present invention.
Reference numerals: the device comprises a glass sampling tank 1, a buffer tank 2, a vacuum pump 3, a reaction kettle 4, a material outlet valve a and an air breaking valve b.
Detailed Description
The following describes the sampling device of the epoxy fatty acid methyl ester reaction kettle in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, the sampling device of the epoxy fatty acid methyl ester reaction kettle of the utility model comprises a glass sampling tank 1, a buffer tank 2 and a vacuum pump 3; the upper inlet of the glass sampling tank 1 is connected with a copper pipe, the other end of the copper pipe extends into the middle of the reaction kettle 4, and the bottom of the glass sampling tank 1 is provided with a material outlet valve a; an upper inlet of the buffer tank 2 is connected with an upper outlet of the glass sampling tank 1 through a copper pipe, and the bottom of the buffer tank 2 is provided with an air breaking valve b; and the vacuum pump 3 is connected with an upper outlet of the buffer tank 2 through a copper pipe.
During the sampling operation, close material outlet valve an and broken empty valve b earlier, open vacuum pump 3, through observing glass sample jar 1, close vacuum pump 3 when the sample reaches a certain amount, open broken empty valve b at this moment and break empty, open material outlet valve an after breaking empty again and can take a sample.
