Description

Technical Field

[0001] The utility model relates to the technical field of metering tanks, in particular to a novel methanol metering tank. Background Art

[0002] Methanol, also known as hydroxymethane, has the chemical formula CH3OH and is composed of a methyl group connected to a hydroxyl group. It is a light, volatile, colorless, flammable liquid with a unique smell similar to ethanol (drinking alcohol). It is used to manufacture formaldehyde and pesticides, and is used as an extractant for organic matter and a denaturant for alcohol. It is usually made by the reaction of carbon monoxide and hydrogen. In chemical production, a metering tank is generally used to hold methanol solutions to facilitate metering of the solutions. When in use, the access pipe is generally located at the upper end of the tank body. When adding liquid, the solution falls from a high place and hits the liquid surface, which can easily cause the solution inside the tank body to be shaken, affecting the reading.

[0003] In order to avoid affecting the readings, Chinese patent application number CN202220756150.5 discloses a methanol metering tank for formaldehyde production. By setting a liquid separator and a liquid collecting bucket, the formaldehyde solution is collected by the liquid collecting bucket to prevent it from directly hitting the liquid surface. At the same time, three liquid separators with drainage holes are used to disperse the solution, thereby further reducing the impact on the liquid surface and improving the accuracy of the readings. However, the following defects still exist: a. Since the drainage holes are evenly arranged in the vertical direction, the liquid surface will still be impacted when the liquid is introduced, affecting the readings. b. When the main body of the device, that is, the tank body, is not vertical to the horizontal plane, it will also affect the accuracy of the readings. Utility Model Content

[0006] Preferably, the partition is inclined, and the liquid inlet pipe is located above the partition and adjacent to the upper end of the partition.

[0007] Preferably, a transparent observation window is provided on one side of the tank body, and the observation window is located on a side wall of the chamber connected to the liquid outlet pipe.

[0013] Beneficial effects achieved by the utility model:

[0014] Compared with the prior art, the utility model is a new type of methanol metering tank, which divides the tank body into two left and right chambers by setting a partition, and sets a connecting hole to connect the bottoms of the two chambers. When liquid enters the chamber connected thereto from the liquid inlet pipe, the connecting hole is located at the bottom of the partition, so that the liquid level of the other chamber shows a steady upward trend, reducing or avoiding the shaking and impact of the liquid level of the other chamber, and improving the accuracy of the reading.
