Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a methyl ester quantitative weighing and feeding device. Background Art

[0002] Methyl ester, also known as fatty acid methyl ester, is the raw material for a widely used surfactant (SAA). The applicant currently uses an open container and an electronic scale to quantitatively weigh the methyl ester during the production process. Specifically, the methyl ester in the storage tank is first placed into the open container through a manual valve. The weight of the methyl ester is then roughly determined based on the reading on the electronic scale and the manual valve is closed. Finally, the methyl ester is accurately weighed using a handle container and then pumped into the production workshop. However, because the volatilization of methyl ester produces an unpleasant odor and irritates the respiratory mucosa, operators often need to wear gas masks, which makes the operation cumbersome and reduces work efficiency. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a methyl ester quantitative weighing and feeding device, which realizes quantitative weighing and automatic feeding of methyl ester through the coordination between the feeding tank, the gas pipeline and the material pipeline, thereby solving the problems of cumbersome operation and low work efficiency in the prior art.

[0004] To solve the above technical problems, the present invention provides a technical solution: a methyl ester quantitative weighing and feeding device, comprising a feeding tank, characterized in that: a buffer channel is connected to the top of the feeding tank, a discharge pipe with a discharge valve is connected to the bottom of the feeding tank, a discharge pipe, a feed pipe and a gas pipe are connected to the buffer channel in sequence from bottom to top, a liquid level gauge is provided on the buffer channel, the height of the discharge pipe coincides with the quantitative feeding scale on the buffer channel, and the quantitative feeding scale is within the range of the liquid level gauge;

[0005] The gas pipeline is connected to the exhaust gas pipeline and the compressed gas pipeline through a tee, and the exhaust gas pipeline and the compressed gas pipeline are respectively provided with an exhaust gas valve and a compressed gas valve.

[0006] Furthermore, the discharge pipe is connected to the top of the temporary storage tank through a discharge valve, the temporary storage tank is connected to the storage tank through a pump, the feed pipe is connected to the bottom of the storage tank through a feed valve, and the storage tank is above the feed pipe, and a respirator is provided on the temporary storage tank.

[0007] Furthermore, the temporary storage tank is made of transparent plastic.

[0008] Furthermore, the top of the buffer channel is connected to a pressure gauge.

[0009] Furthermore, a transparent pipe is provided on the discharge pipe between the discharge valve and the loading tank.

[0010] The beneficial effects of the utility model are:

[0011] In the present application, the height of the storage tank is higher than that of the buffer channel. The exhaust valve on the exhaust pipe is opened to enable the methyl ester in the storage tank to automatically flow into the loading tank. When the methyl ester flows into the temporary storage tank through the discharge pipe, the scale on the liquid level gauge is stable. At this time, the quantitative weighing of the methyl ester is achieved, and then the methyl ester in the loading tank is pressed out to the production equipment by compressed gas. The methyl ester flows in a sealed device throughout the process, reducing the amount of methyl ester volatilization and improving the environmental quality. At the same time, the temporary storage tank is made of transparent plastic, which is convenient for personnel to observe the amount of methyl ester in the temporary storage tank and to pump the methyl ester in the temporary storage tank into the storage tank by a pump. The setting of the pressure gauge makes it convenient for personnel to observe the gas pressure value in the loading tank to prevent the occurrence of accidents. The setting of the transparent pipe makes it convenient for personnel to observe whether the methyl ester in the loading pipe is completely discharged.

The height of the discharge pipe 5 coincides with the quantitative feeding scale on the buffer channel 2, and the quantitative feeding scale is within the range of the liquid level gauge 8. When methyl ester flows from the discharge pipe 5, the methyl ester in the feeding tank is at a stable height. The quantitative operation of methyl ester can also be observed and displayed by the liquid level gauge 8.

[0020] The gas pipeline 7 is connected to the exhaust gas pipeline 9 and the compressed gas pipeline 107 respectively through a tee, and the exhaust gas pipeline 9 and the compressed gas pipeline 107 are respectively provided with an exhaust valve 11 and a compressed gas valve 12; the discharge pipeline 5 is connected to the top of the temporary storage tank 17 through the discharge valve 12, the temporary storage tank 17 is connected to the storage tank 15 through the pump 14, the feed pipeline 6 is connected to the bottom of the storage tank 15 through the feed valve, and the storage tank 15 is above the feed pipeline 6, and a respirator is provided on the temporary storage tank 17, which facilitates the flow of methyl ester into the temporary storage tank 17 or facilitates the pump 14 out of the methyl ester in the temporary storage tank 17; the height of the storage tank is higher than the height of the buffer channel 2, and the exhaust valve 11 on the exhaust gas pipeline 9 is opened to realize the automatic flow of methyl ester in the storage tank into the loading tank, and when the compressed gas pipeline 107 is opened, the compressed gas enters the loading tank, and the methyl ester in the loading tank passes through by the pressure of the compressed gas.

[0021] A transparent pipe 16 is provided on the discharge pipe 4 between the discharge valve 3 and the feeding tank; by determining whether there is methyl ester in the transparent pipe 16, it is determined whether the methyl ester in the feeding pipe is completely discharged. Example 2

[0022] like Figure 1 As shown, this embodiment is obtained by changing the structure of technical features such as the slider 3 on the basis of the embodiment one. The remaining technical features are the same as those of the embodiment one, and the similarities are not repeated here. Among them, the difference between this embodiment and the embodiment one is that: the temporary storage tank 17 is made of transparent plastic; and a pressure gauge is connected to the top of the buffer channel 2.

[0023] In this embodiment, the temporary storage tank 17 is made of transparent plastic, which makes it easy for personnel to observe the amount of methyl ester in the temporary storage tank 17 and to pump the methyl ester in the temporary storage tank 17 into the storage tank through the pump 14; the setting of the pressure gauge makes it easy for personnel to observe the gas pressure value in the feeding tank to prevent the occurrence of accidents.

[0024] The use process of the technical solution formed by the above embodiments is as follows: the discharge valve 3, the exhaust valve 11, the compressed gas valve 12, the discharge valve 12 and the feed valve are all in the closed state.

[0025] Manually open the waste valve 11, the discharge valve 12 and the feed valve. The methyl ester in the storage tank automatically flows into the loading tank through the feed valve and the gas in the loading tank is discharged through the waste valve 11. When the methyl ester in the loading tank flows into the temporary storage tank 17 from the discharge pipe 5, it means that the methyl ester in the loading tank is at the calibrated weight. First manually close the feed valve, then manually close the waste valve 11 and the discharge valve 12, open the discharge valve 3 and the compressed gas valve 12, and after the compressed gas enters the loading tank, the methyl ester is discharged from the loading tank through the discharge valve 3. When no methyl ester is observed in the transparent tube, close the discharge valve 3 and the compressed gas valve 12 to complete the automatic loading operation.

[0026] When the personnel observe that the amount of methyl ester in the temporary storage tank 17 is too much, the pump 14 is operated by switching on and off to transfer the methyl ester in the temporary storage tank 17 to the storage tank 15 .

[0027] Note that the above are merely preferred embodiments of the present invention and the technical principles employed. Those skilled in the art will appreciate that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments, and substitutions are readily apparent to those skilled in the art without departing from the scope of protection of the present invention. Therefore, while the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments and may include many other equivalent embodiments without departing from the scope of the present invention. The scope of the present invention is determined by the appended claims.
