Description

Technical Field

[0001] The utility model relates to the technical field of furan resin production, in particular to a metering device for producing furan resin materials. Background Art

[0002] Furan resin is a general term for a class of synthetic resins containing furan rings in their molecular structures. There are three main types of furan resins: furfuryl alcohol resin, furfural-acetone resin and furfural-acetone-formaldehyde resin. Since they all contain furan rings in their molecular structures, they have many common characteristics in terms of performance, such as outstanding alkali resistance, acid resistance, solvent resistance and heat resistance. Furan resin is a general term for a class of polymers made from furfural as the basic raw material. Furfural is the most basic raw material for making furan resins, which comes from agricultural and sideline products such as cottonseed hulls, rice husks, corn cobs and corn stalks.

[0003] In the production process of furan resin, the raw materials need to be accurately measured. At present, manual scales are used for measurement. For example, a Chinese patent discloses a metering device for producing furan resin materials (authorization announcement number CN217120196U). The patented technology can be provided with a liquid level sensor, a controller, a first check valve, a second check valve, and a metering cylinder. The liquid level sensor measures the liquid level of the raw material and transmits the data to the controller. The controller controls the first check valve according to the received information. When the preset liquid level is reached, the first check valve is closed and the second check valve is opened, so that the raw material in the metering cylinder enters the reaction device, thereby realizing accurate measurement of the raw material;

[0004] However, the metering device disclosed above still has some defects when used: the device can only meter liquid raw materials, but cannot meter powdery raw materials, nor can it adjust the capacity of the metering cylinder, and cannot adapt to adjust the metering size, which affects the convenience of furan resin production. Therefore, those skilled in the art provide a metering device for producing furan resin materials to solve the problems raised in the above background technology. Utility Model Content
