Description

Technical Field

[0001] This utility model relates to the field of saccharification liquid processing technology, and specifically discloses an activated carbon decolorization device for saccharification liquid. Background Technology

[0002] In industries such as food and pharmaceuticals, the decolorization of saccharified solutions is a crucial step. As a raw material or intermediate, the color of the saccharified solution directly affects the product's appearance, quality, and market acceptance. Taking the food industry as an example, in the production of sugars and beverages, consumers often prefer products with clear, pure colors. If the saccharified solution is too dark, the final product will appear cloudy and of poor quality, reducing consumer willingness to purchase. In the pharmaceutical field, drug quality is crucial to health and life. Pigment impurities in the saccharified solution can interfere with the purity, stability, and efficacy of drugs. Strict quality standards require efficient and precise decolorization of the saccharified solution.

[0003] Traditional decolorization methods for saccharification solutions typically use a single tank for activated carbon decolorization. In single-tank operation mode, after each decolorization is completed, the entire production process must be paused for solid-liquid separation and activated carbon cleaning. This not only causes production interruptions and consumes a lot of time in non-production processes, but also greatly reduces production efficiency and makes it difficult to meet the growing demand for large-scale production.

[0004] Furthermore, the traditional method for cleaning used activated carbon is mostly manual cleaning, which is cumbersome, time-consuming, labor-intensive, inconvenient, and affects the efficiency of decolorization of saccharification solution. Utility Model Content

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0025] Please see Figure 1-4 An activated carbon decolorization device for saccharification liquid includes a base plate 1, and an adjustment mechanism and a decolorization mechanism are provided on the upper end surface of the base plate 1.

[0026] The decolorization mechanism includes a fixed platform 2 fixedly installed on the upper surface of the base plate 1. The upper surface of the fixed platform 2 has a through hole 201. A support rod 3 rotatably connected to the base plate 1 is movably installed inside the through hole 201 via a bearing. Two decolorization tanks 4 are arranged in a group symmetrically on the outer wall of the support rod 3. The bottom of the decolorization tank 4 is connected to a discharge pipe 401 with a valve. A collection box 5 fixedly installed on the upper surface of the base plate 1 is located below the right decolorization tank 4. A top cover 6 is installed on the top of the collection box 5. A semi-circular filter screen 602 is installed inside the collection box 5. A spiral conveying rod 603 is installed inside the filter screen 602. A discharge port 605 located at the right end of the spiral conveying rod 603 is provided on the right side wall of the collection box 5.

[0027] The adjustment mechanism includes a side plate 7 fixedly installed on the left side of the upper surface of the base plate 1. A movable plate 8 is provided on the right side of the side plate 7. A cylinder cover is fixedly installed on the bottom of the movable plate 8. A stirring rod 802 is located directly above one of the decolorizing tanks 4 at the bottom of the cylinder cover.

[0028] In this embodiment: the saccharified liquid to be decolorized and activated carbon are added sequentially into two decolorization tanks 4. The position of the moving plate 8 is adjusted so that the top cover 6 covers the corresponding decolorization tank 4. The stirring rod 802 stirs the saccharified liquid and activated carbon. Under the stirring action, the activated carbon is evenly dispersed in the saccharified liquid. The saccharified liquid is decolorized by the adsorption effect of the activated carbon. The two decolorization tanks 4 are rotated 180 degrees by the driving mechanism. The valve on the feed pipe 401 of the decolorization tank 4 is opened, and the decolorized saccharified liquid and activated carbon are fed from the feed hopper 601 into the collection box 5. At this time, the filter screen 602 separates the decolorized saccharified liquid and activated carbon. The decolorized saccharified liquid can be collected at the bottom of the collection box 5. The spiral conveyor rod 603 rotates to clean the activated carbon left on the filter screen 602 and convey it out from the discharge port 605, thereby automatically completing the cleaning, which not only saves manpower but also improves work efficiency.

[0029] Next, rotate to the decolorization tank 4 below the stirring rod 802. The above operations can be repeated to stir, feed, filter, and collect the saccharification liquid and activated carbon inside. This allows the two tanks to work alternately. When one tank is undergoing a decolorization reaction, the other tank can simultaneously perform subsequent operations such as filtration or activated carbon cleaning. There is no need to wait for a complete decolorization process to end, which greatly shortens the overall production cycle, realizes continuous production, increases the amount of saccharification liquid processed per unit time, and meets the needs of large-scale production.

[0030] As a technical optimization of this utility model, a "T"-shaped sliding groove 701 is provided on the right side wall of the side plate 7. An electric push rod 702 is installed inside the sliding groove 701. The left end of the moving plate 8 is slidably connected to the inner side of the sliding groove 701, and the bottom is fixedly connected to the output end of the electric push rod 702.

[0031] In this embodiment: by activating the electric actuator 702, the movable plate 8 can be pushed to move along the slide groove 701. The slide groove 701 can restrict the moving direction of the movable plate 8, thereby enabling the movable plate 8 to move stably.

[0032] As a technical optimization of this utility model, a drive mechanism is provided on the outer side of the fixed platform 2. The drive mechanism includes a third motor 9 installed on the upper surface of the base plate 1. The drive mechanism also includes two synchronous pulleys 901. The outer wall of the fixed platform 2 has a port 202 that communicates with the through hole 201. One synchronous pulley 901 is fixedly installed at the output end of the third motor 9, and the other synchronous pulley 901 is located inside the port 202 and fixedly installed on the outer wall of the support rod 3. A synchronous belt 902 is sleeved between the two synchronous pulleys 901.

[0033] In this embodiment: the third motor 9 is a worm gear motor with a self-locking function. By starting the third motor 9, the synchronous pulley 901 connected to it can be driven to rotate, which in turn drives the synchronous pulley 901 to drive another synchronous pulley 901 to rotate through the synchronous belt 902, thereby driving the support rod 3 to rotate.

[0034] As a technical optimization of this utility model, a second motor 801 is installed on the upper end of the movable plate 8, and the output end of the second motor 801 is coaxially and fixedly connected to the stirring rod 802.

[0035] In this embodiment: by starting the second motor 801, the stirring rod 802 can be driven to rotate, which facilitates the stirring and mixing of the saccharification liquid and activated carbon in the decolorization tank 4.

[0036] As a technical optimization of this utility model, a first motor 604 is installed on the left side wall of the collection box 5 via a base, and the output end of the first motor 604 is coaxially and fixedly connected to the left end of the screw conveyor 603.

[0037] In this embodiment: by starting the first motor 604, the spiral conveyor rod 603 rotates to transport and clean the activated carbon on the filter screen 602.

[0038] As a technical optimization of this utility model, two fixing rings 301 are fixedly installed on the outer side wall of the support rod 3, which are respectively fixedly installed on the outer side wall of the decolorization tank 4.

[0039] In this embodiment, the position of the decolorizing tank 4 is fixed by installing the fixing ring 301.

[0040] As a technical optimization of this utility model, the top of the collection box 5 is provided with a feed hopper 601 located directly below one of the feed pipes 401, and the bottom of the right side wall of the collection box 5 is connected to a drain pipe with a valve.

[0041] In this embodiment: by setting up a feed hopper 601, it is convenient for the feed pipe 401 to discharge the saccharification liquid and the adsorbed activated carbon into the interior of the corresponding feed hopper 601. By opening the valve, the drain pipe discharges the decolorized saccharification liquid.

[0042] The working principle and usage process of this utility model are as follows: In use, the device is electrically connected to an external power source and controller. Then, the operator adds the saccharified liquid to be decolorized and activated carbon to two decolorization tanks 4 in sequence. Next, the electric push rod 702 is activated, which moves the moving plate 8, the second motor 801, the top cover 6, and the stirring rod 802, so that the top cover 6 covers the corresponding decolorization tank 4. At this time, the stirring rod 802 is located inside the decolorization tank 4. Then, the second motor 801 is activated, driving the stirring rod 802 to stir the saccharified liquid and activated carbon. Under the stirring action, the activated carbon is evenly dispersed in the saccharified liquid, utilizing the adsorption effect of the activated carbon to decolorize the saccharified liquid. Next, the stirring rod 802 is moved upwards away from the decolorization tank 4, and the third motor 9 is activated. The two synchronous pulleys 901 rotate simultaneously via the synchronous belt 902, which drives the support rod 3, the two fixing rings 301, and the two decolorization tanks 4 to rotate 180 degrees, causing the decolorization tank 4 to rotate after mixing. Above the feed hopper 601, the valve on the discharge pipe 401 of the decolorizing tank 4 is opened, allowing the decolorizing saccharified liquid and activated carbon to be fed from the feed hopper 601 into the collection box 5. At this time, the filter screen 602 separates the decolorizing saccharified liquid and activated carbon. The decolorized saccharified liquid can be collected at the bottom of the collection box 5. The first motor 604 is started, causing the screw conveyor 603 to rotate to clean and transport the activated carbon remaining on the filter screen 602, and then discharge it from the discharge port 605. Then, it rotates to the decolorizing tank 4 below the stirring rod 802, and the above operation can be repeated to stir, feed, filter and collect the saccharified liquid and activated carbon inside, so that the two tanks work alternately. When one tank is undergoing a decolorization reaction, the other tank can simultaneously perform subsequent operations such as filtration or activated carbon cleaning, without waiting for a complete decolorization process to end, which greatly shortens the overall production cycle, realizes continuous production, increases the amount of saccharified liquid processed per unit time, and meets the needs of large-scale production.
