Description

Technical Field

[0001] The invention relates to the technical field of acidification devices, in particular to a gallic acidification device. Background Art

[0002] Gallic acid (GA), chemical name 3,4,5-trihydroxybenzoic acid, also known as gallic acid, gallic acid, gallic acid is white or light yellow needle crystals or powder, usually in the form of monohydrate, with a specific gravity of 1.694 and a melting point of 235-240°C. At present, gallic acid is usually prepared by hydrolysis of tannin-containing biomass such as gallic acid or tara through acid-base method, fermentation method or enzymatic method, and then gallic acid is used as raw material to prepare pyrogallic acid through vacuum decarboxylation, normal pressure decarboxylation, pressurized decarboxylation or microbial decarboxylation. However, its yield and purity are not high.

[0003] For example, a Chinese patent with publication number "CN110922327B" discloses "a gallic acidification device", whose main structure includes an industrial computer, a water storage tank, a spray pump, a spray pipe, a spray head, an acidification mechanism, an exhaust pipe, a packing purification tower and a pH sensor. By setting up the acidification mechanism, a stirring motor is first used to drive a stirring paddle to stir hydrochloric acid and activated carbon, and the gallic acid is placed on a storage net and immersed in hydrochloric acid for acidification. After the glass sliding door is closed, the acid mist and some exhaust gas generated during the acidification are discharged, and spraying, acidification and acid mist treatment are integrated, which effectively improves the acidification efficiency of the gallic acid; the spray pump transmits the tap water in the water storage tank to the spray head through the spray pipe, and then sprays the acid mist generated in the acidification box, recovers the acid mist, prevents waste of resources, and reduces the emission of acid mist in the exhaust gas.

[0004] By carefully understanding the above-mentioned gallic acidification device, it can be learned that: it sets up an acidification mechanism, first uses a stirring motor to drive a stirring paddle to stir the hydrochloric acid and activated carbon, puts the gallic acid on the storage net, and immerses it in hydrochloric acid for acidification. However, since the gallic acid is placed on the storage net in a static form, the gallic acid is immersed in the mixed medium of hydrochloric acid and activated carbon in a relatively static form, and since the fluidity between the gallic acid and the mixed medium required for immersion is relatively low, the efficiency of gallic acidification is relatively low. At the same time, after the acidification is completed, the gallic acid needs to be taken out and the mixed medium of hydrochloric acid and activated carbon needs to be separated, and the equipment itself cannot achieve the corresponding separation function, which further leads to low working efficiency of the equipment.

A mist discharge hole 11 is provided at the top of the body 1 and is connected to the columnar acidification cavity 3, and a sealing cover 12 is inserted into the material delivery port 10 and can be removed. The mist discharge hole 11 is connected to the feed port of the equipment for treating mist through a pipeline, and then the sealing cover 12 is opened, and hydrochloric acid and activated carbon are quantitatively poured into the columnar acidification cavity 3, and then the driving motor 8 is turned on to make the hydrochloric acid and activated carbon fully mixed, and then gallic acid is poured into the columnar acidification cavity 3, the sealing cover 12 is closed, and then the driving motor 8 is turned on to acidify the gallic acid. During the acidification process, mist is generated, and the mist enters the equipment for treating mist through the mist discharge hole 11, thereby realizing effective treatment of the mist.

[0024] To achieve agitation and discharge of the mixed medium and gallic acid, please refer to Figure 2 , Figure 3 and Figure 4 , it is necessary to set up a driven rotating mechanism 14, which is provided with a rotating stirring wing 144 located inside the cylindrical acidification cavity 3 and capable of rotating with the rotor 13 so that the raw materials located around it can be stirred, and a spiral blade structure 146 located inside the funnel-shaped acidification cavity 4 and the object conveying channel 5 and capable of causing the raw materials located around it to produce a longitudinal movement effect when rotating. When the driving motor 8 is started, the direction of the rotor 13 is controlled so that the driving direction generated by the spiral blade structure 146 when rotating is upward, so that the mixed medium composed of hydrochloric acid and activated carbon and the gallic acid circulate under the action of their own gravity and the spiral blade structure 146, and the rotating stirring wing 144 can also cause a rapid flow effect between the mixed medium and the gallic acid, thereby accelerating the efficiency of gallic acidification. When the gallic acid is completely acidified, the direction of the rotor 13 is controlled so that the driving direction generated by the spiral blade structure 146 when rotating is downward, so that the acidified gallic acid produces a downward movement direction, thereby realizing the separate discharge of the gallic acid.

[0025] For the specific structure of the driven rotating mechanism 14, please refer to Figure 3 and Figure 4 , including an upper hollow rotating shaft 141 located inside the cylindrical acidification cavity 3, the top center of the upper hollow rotating shaft 141 is provided with a No. 1 shaft fixing groove 142 with an inner concave structure and used to fix and install the rotor 13, the bottom center of the upper hollow rotating shaft 141 is provided with a lower hollow rotating shaft 143 with an integral structure therewith and extending deep into the funnel-shaped acidification cavity 4 and the object conveying channel 5, the top end of the lower hollow rotating shaft 143 is flush with the top end of the funnel-shaped acidification cavity 4, and the bottom end is flush with the bottom end of the object conveying channel 5, the upper hollow rotating shaft 141 A plurality of rotating stirring wings 144 are fixedly mounted on the outer circumference surface of the lower hollow rotating shaft 143, and a spiral blade structure 146 which is an integral structure therewith is provided on the outer circumference surface of the lower hollow rotating shaft 143. In order to realize the spiral conveying of gallons, it is necessary to make the dimension between each two adjacent spiral teeth in the spiral blade structure 146 not less than the dimension of gallons. An upper component movable cavity 145 is provided inside the upper hollow rotating shaft 141, and an axial movable hole 147 is provided inside the lower hollow rotating shaft 143, the bottom end of which is in an open state and the top end of which is connected to the bottom end of the upper component movable cavity 145.

[0026] To achieve a separate discharge effect for gallic acid, see Figure 2 , Figure 5 and Figure 6, an elastic damping mechanism 15 is required, in which a lower limit plate 155 is provided which can abut against the bottom of the upper limit plate 6 to prevent the raw material from being discharged downward from the object conveying channel 5, and a spiral spring 154 which can produce an upward elastic damping effect on the lower limit plate 155. The gallic acid is generated by the rotation of the spiral blade structure 146 to move downward, and will eventually be squeezed between the bottom of the spiral blade structure 146 and the upper surface of the lower limit plate 155. As the number of gallic acid increases, when the force of the gallic acid on the lower limit plate 155 is greater than the elastic effect of the spiral spring 154, the gallic acid will be squeezed between the bottom of the spiral blade structure 146 and the upper surface of the lower limit plate 155. When force is applied, the lower limit plate 155 will move downward. Of course, since the gallic acid is in a squeezed state, the mixture medium composed of hydrochloric acid and activated carbon cannot leak out through the gallic acid. At this time, the docked gallic acid can be collapsed and fall by applying a force horizontally to the docked gallic acid through the stick, and the lower limit plate 155 can be quickly reset under the elastic action of the coil spring 154, thereby achieving a separate discharge effect for the gallic acid. When it is necessary to discharge the mixed medium, the lower limit plate 155 can be pushed downward using a tool to discharge the mixed medium under the action of gravity.

[0027] For the specific structure of the elastic damping mechanism 15, please refer to Figure 5 and Figure 6 , including an inner movable plate 151 located inside the upper component movable cavity 145 and capable of axially moving along the upper component movable cavity 145, the bottom of the inner movable plate 151 is provided with a second shaft body fixing groove 152 of an inner concave structure, the inner movable plate 151 is provided with a longitudinal telescopic shaft 153 capable of relative rotation through a bearing inside the second shaft body fixing groove 152, the shaft body of the longitudinal telescopic shaft 153 passes through the shaft body movable hole 147, and the bottom end is fixedly provided with a lower limit plate 155 that abuts against the bottom of the upper limit plate 6, the longitudinal The telescopic shaft 153 is provided with a coil spring 154 on the outer periphery of the shaft body located inside the movable cavity 145 of the upper component. In order to have a sufficient range of motion, it is necessary to make the inner movable plate 151 located in the middle area of ​​the movable cavity 145 of the upper component in the initial state. In order to provide an elastic force, it is necessary to make the initial length of the coil spring 154 greater than the depth of the movable cavity 145 of the upper component, and the bottom end of the coil spring 154 abuts against the bottom end of the movable cavity 145 of the upper component, and the top end abuts against the bottom end of the inner movable plate 151.

[0028] When in use, the mist discharge hole 11 is connected to the feed port of the equipment for treating mist through a pipeline, and then the sealing cover 12 is opened, and hydrochloric acid and activated carbon are quantitatively poured into the columnar acidification cavity 3, and then the driving motor 8 is turned on to make the hydrochloric acid and activated carbon fully mixed, and then the gallic acid is poured into the columnar acidification cavity 3, the sealing cover 12 is closed, and then the driving motor 8 is turned on. When the driving motor 8 is started, the direction of the rotor 13 is controlled so that the driving direction generated by the spiral blade structure 146 during rotation is upward, so that the mixed medium composed of hydrochloric acid and activated carbon and the gallic acid circulate under the action of their own gravity and the spiral blade structure 146, and the rotating stirring wings 144 can also produce a rapid flow effect between the mixed medium and the gallic acid. During the acidification process, mist is generated, and the mist enters the equipment for treating mist through the mist discharge hole 11, so that the mist is effectively treated. When the gallic acid is completely acidified, the direction of the rotor 13 is controlled so that The driving direction generated by the spiral blade structure 146 when rotating is downward, and the gallic acid has a downward movement trend due to the rotation of the spiral blade structure 146, and will eventually be squeezed between the bottom of the spiral blade structure 146 and the upper surface of the lower limit plate 155. As the number of gallic acid continues to increase, when the force of the gallic acid on the lower limit plate 155 is greater than the elastic force of the spiral spring 154, the lower limit plate 155 will move downward. Of course, since the gallic acid is in an squeezed state, the mixture medium composed of hydrochloric acid and activated carbon cannot leak out through the gallic acid. At this time, by applying a force to the docked gallic acid laterally through the stick, the docked gallic acid can collapse and fall, and the lower limit plate 155 can be quickly reset under the elastic action of the spiral spring 154, thereby achieving a separate discharge effect for the gallic acid. When it is necessary to discharge the mixed medium, a tool is used to push the lower limit plate 155 downward, so that the mixed medium can be discharged under the action of gravity.
