Description

Technical Field

[0001] The utility model relates to the technical field of hydrolysis pots, in particular to a hydrolysis pot for producing uniformly mixed aldehyde. Background Art

[0002] Furfural and aldehyde are the same substance, which is a derivative in which the hydrogen atom at the 2-position of furan is replaced by an aldehyde group. It appears as a colorless, transparent, oily liquid with a special smell similar to benzaldehyde. When exposed to light and air, its color quickly changes to reddish brown and it easily evaporates with steam. Furfural was originally produced by heating rice bran with dilute acid, so it is called furfural. Furfural is formed by the hydrolysis of pentosans under the action of acid to form pentoses, and then by the dehydration and cyclization of pentoses. The main raw materials for its production are agricultural and sideline products such as corn cobs. Furfural is one of the most important derivatives of the furan ring system, with active chemical properties. It can produce numerous derivatives through oxidation, condensation and other reactions. It is widely used in synthetic plastics, medicine, pesticides and other industries. In industrial production, aldehyde production hydrolysis pots are usually used.

[0003] In the prior art, the reaction system in the aldehyde hydrolysis pot is acidic, which will cause corrosion of the stirring paddle and require frequent replacement of the stirring paddle. However, the stirring paddle of the existing aldehyde hydrolysis pot is troublesome to replace, and only using the stirring paddle for stirring has a low stirring efficiency for the liquid material, resulting in uneven mixing of the liquid material. During the reaction, some materials will stick to the inner wall of the hydrolysis pot and cannot participate in the reaction. Therefore, in view of the above problems, a aldehyde production hydrolysis pot with uniform mixing is proposed. Utility Model Content

[0004] The utility model aims to provide a homogeneously mixed aldehyde production hydrolysis pot to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The top end of the pot cover is embedded with a vertically arranged rotating motor, the output end of the rotating motor is fixedly connected to a vertically arranged rotating shaft, the bottom end of the rotating shaft is provided with a limiting groove, the inner side of the limiting groove is slidably connected with a vertically arranged limiting rod, the outer side of the rotating shaft is provided with a through groove penetrating the rotating shaft, the one side of the through groove is provided with a clamping groove penetrating the limiting rod, the inner side of the clamping groove is clamped with a clamping block, one end of the clamping block is fixedly connected with a horizontally arranged stirring blade, the bottom end of the rotating shaft is fixedly connected with a threaded ring that passes through the limiting groove, the outer side of the threaded ring is spirally connected with a threaded barrel, the inner side of the threaded barrel is fixedly connected with the limiting block, the end of the stirring blade away from the clamping block is fixedly connected with a vertically arranged scraper, and the side of the scraper away from the stirring blade is fixedly connected with a vertically arranged rubber strip.

[0007] Preferably, an air pressure pump is provided outside the hydrolysis pot, a valve communicating with the air pressure pump is fixedly connected to the side of the air pressure pump close to the hydrolysis pot, and a nozzle communicating with the valve is fixedly connected to the end of the valve away from the air pressure pump.

[0008] Preferably, the number of the air pressure pump, valve and nozzle are all two, and one end of the nozzle close to the valve is fixedly connected to the inner side of the hydrolysis pot.

[0009] Preferably, the number of the passing grooves, the engaging blocks and the stirring blades is eight, the number of the engaging grooves is four, and the number of the scrapers and the rubber strips is two.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] When the stirring blade needs to be disassembled, the threaded barrel is unscrewed from the outside of the threaded ring, and the stirring blade is pressed downward, and the limiting rod can slide inside the limiting groove until the locking groove is aligned with the passing groove, and the stirring blade is taken out, thereby replacing a new stirring blade.

[0013] 2. In the utility model, the scraper, rubber strip, air pressure pump, valve and nozzle are arranged, so that the materials inside the hydrolysis pot can be mixed more evenly. When the materials need to be mixed, the rotating motor and the air pressure pump are started, and the valve is opened. The air pressure pump inputs the gas into the inside of the hydrolysis pot through the valve and the nozzle. At this time, the rotating shaft rotates to break up the input air and mix the materials evenly. The scraper and rubber strip located at one end of the stirring blade can continuously scrape the materials on the inner wall of the hydrolysis pot to prevent materials from not participating in the reaction.
