Description

Technical Field

[0001] The utility model relates to the technical field of hydrolysis reaction, in particular to a hydrolysis reaction device. Background Art

[0002] In organic chemistry, hydrolysis refers to the reaction of water with another compound, which decomposes into two parts. H+ in water is added to one part, and hydroxyl is added to the other part, thus obtaining two or more new compounds. In inorganic chemistry, it refers to the reaction of weak acid radicals or weak base ions with water to generate weak acids and hydroxide ions. The hydrolysis of organic matter is more widely used in industry, mainly producing alcohols and phenols.

[0003] When the existing hydrolysis reaction device is in use, the hydrolysis reaction will produce some solid residues adhering to the inner wall of the reaction device. In this way, the solid residues are not easily discharged through the discharge port along with the water. Therefore, the staff needs to disassemble and open the reaction device to clean the adhering solid residues. Otherwise, these solid residues will affect the efficiency of the next hydrolysis reaction. Utility Model Content

[0004] The purpose of the utility model is to provide a hydrolysis reaction device in order to solve the above problems.

[0006] A hydrolysis reaction device comprises a reactor, wherein the top of the reactor is connected to a feed inlet for replenishing raw materials, the bottom of the reactor is connected to a discharge port for discharging products after the reaction is completed, a stirring rod for stirring materials to accelerate the reaction is rotatably connected inside the reactor, a motor for driving the stirring rod to rotate is installed on one side of the reactor, a scraper for scraping off reaction residues on the inner wall of the reactor is slidably connected to the inner wall of the reactor, and a one-way rotating component for driving the scraper to rotate is installed on the reactor.

[0007] Preferably, the one-way rotating component includes a rotating sleeve for driving the scraper to rotate, the inner wall of the rotating sleeve is fixedly connected to a baffle for driving the rotating sleeve to rotate, the inner wall of the rotating sleeve is connected to a baffle rod for pushing the baffle to rotate through a torsion spring shaft, and the outer wall of the stirring rod is fixedly connected to a ratchet for pushing the baffle rod to move.

[0008] Preferably, the scraper is composed of an L-shaped strip and a semicircular strip, and the movement trajectory of the scraper can cover the inner wall of the reactor except for the area blocked by the rotating sleeve.

[0009] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0010] In the present application, when the hydrolysis reaction is carried out, the staff first turns on the motor to rotate the stirring rod clockwise, so that the stirring rod will not push the baffle rod to rotate when driving the ratchet to rotate. After the hydrolysis reaction is completed, the staff can reverse the motor, and the motor will drive the stirring rod to rotate counterclockwise, the ratchet will squeeze the baffle rod, and the baffle rod will be blocked by the baffle plate and cannot rotate. The baffle rod will push the baffle plate to rotate the rotating sleeve, and the rotating sleeve will drive the scraper to rotate, and the scraper will scrape off the solid residue adhering to the inner wall of the reactor.
