Description

Technical Field

[0001] The utility model belongs to the technical field of alcohol product processing, and particularly relates to a dehydrogenation separation device for alcohol products. Background Art

[0002] Dehydrogenation of alcohols involves removing hydrogen atoms from alcohols to produce the corresponding olefins or other hydrogen-free compounds. This process typically involves a catalytic dehydrogenation reaction, where a catalyst promotes the breaking of the hydrogen-carbon bond in the alcohol molecule, forming a double bond and water as reaction products.

[0003] Current alcohol dehydrogenation separation units typically utilize built-in heating rods to achieve controlled heating during the reaction process. These rods are typically fixed to the bottom of the vessel to meet heating requirements. However, this mounting arrangement makes disassembly and installation cumbersome when cleaning, repairing, or replacing the rods, which is not only time-consuming but can also impact production efficiency. Utility Model Content

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a dehydrogenation and separation device for alcohol products, comprising a reactor, a sliding groove is provided on the inner surface of the reactor, a driving motor is fixedly connected to the inner top of the sliding groove, the output end of the driving motor is transmission-connected to a threaded screw, the surface of the threaded screw is threadedly connected to a sliding block, an electric heating rod is provided on the side surface of the sliding block, a sealing cover is snap-connected to the upper surface of the reactor, the upper surface of the sealing cover is fixedly connected to the driving motor, the output end of the driving motor is transmission-connected to a transmission shaft through a transmission gear, and a stirring blade is fixedly connected to the side surface of the transmission shaft.

[0008] Preferably, a valve is installed inside the discharge pipe.

[0009] Preferably, a plurality of legs are fixedly connected to the lower surface of the reactor.

[0010] Preferably, the electric heating rod is rotatably connected to the side surface of the sliding block via a rotating shaft.

[0011] Preferably, a rubber sealing ring is fixedly connected to the lower surface of the sealing cover.

[0012] Compared with the existing technology, the utility model provides a dehydrogenation separation device for alcohol products, which has the following beneficial effects:

[0013] 1. The utility model is provided with a driving motor and a threaded screw rod. When the alcohol product is subjected to dehydrogenation separation, the threaded screw rod is driven by the driving motor to rotate, so that the sliding block is lowered, thereby driving the electric heating rod to descend to the lowest end of the reactor, and the reaction is heated by the electric heating rod. After the reaction is completed, when the electric heating rod needs to be cleaned, the sealing cover is removed, and the threaded screw rod is driven by the driving motor to rotate, so that the sliding block is raised to the highest end. The electric heating rod is then rotated by the rotating shaft so that the electric heating rod is outside the reactor, and the electric heating rod is cleaned by flushing or wiping, effectively avoiding the problem that when the electric heating rod needs to be cleaned, repaired or replaced, this fixing method makes the disassembly and assembly process cumbersome, not only time-consuming but also potentially affecting production efficiency.

[0014] 2. The utility model is provided with a driving motor and stirring blades and other structures. When dehydrogenation separation treatment is carried out on alcohol products, after adding a sufficient amount of catalyst into the reactor, the driving motor drives the transmission shaft to rotate, thereby driving the stirring blades to rotate, and the alcohol product and catalyst inside are fully stirred and mixed, making the reaction more rapid, thereby accelerating the reaction efficiency of the alcohol product.
