Description

Technical Field

[0001] This utility model relates to the field of decolorization technology, specifically to a decolorization device for pharmaceutical solutions. Background Technology

[0002] A decolorizing tank is an important industrial piece of equipment, primarily used to remove pigments and impurities from substances for purification and decolorization. It consists of a tank body, stirring device, heating or cooling device, inlet and outlet ports, and sealing device, and is typically made of high-quality stainless steel, offering excellent corrosion resistance and high-temperature resistance. The working principle of the decolorizing tank is based on physical adsorption or chemical reaction. An adsorbent (such as activated carbon or diatomaceous earth) is added and fully contacted and mixed with the material to be treated, adsorbing the pigments and impurities. Then, the adsorbent is separated from the material through filtration or other separation methods, achieving the decolorization effect. Its applications are wide-ranging, including the chemical, pharmaceutical, food, and environmental protection industries.

[0003] In chemical treatment using decolorization tanks, the solution to be treated and the decolorizing agent are usually poured directly into the tank, followed by heating and stirring to achieve decolorization. To ensure complete decolorization, an excess of decolorizing agent is typically added. However, while this method improves the decolorization effect, it also increases the processing cost. Therefore, a decolorization device for pharmaceutical solutions is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a decolorization device for pharmaceutical solutions to solve the problem of high processing costs in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a decolorizing device for pharmaceutical solutions, comprising a decolorizing tank, an observation window fixedly installed on the decolorizing tank, a discharge port fixedly installed at the bottom of the decolorizing tank, a feed port at the top of the decolorizing tank, a stirring mechanism on the decolorizing tank, the stirring mechanism comprising a drive motor fixedly installed on the decolorizing tank, a stirring shaft fixedly installed at the output end of the drive motor, stirring blades fixedly installed on the stirring shaft, a transmission shaft rotatably installed on one side of the stirring shaft, an electromagnetic clutch on the transmission shaft, and an adding mechanism on one side of the drive motor.

[0006] Preferably, both the drive shaft and the stirring shaft are provided with helical gears, and the two sets of helical gears mesh together. The drive motor is provided with a motor frame, and the drive motor is fixed to the decolorization tank through the motor frame.

[0007] Preferably, a retainer is provided on the inner side of the motor frame, and the drive shaft is rotatably mounted on one side of the stirring shaft through the retainer.

[0008] Preferably, a through hole is provided at the middle position of the top of the decolorizing tank, the stirring shaft extends into the decolorizing tank through the through hole, and the stirring blades are movably installed in the decolorizing tank through the stirring shaft.

[0009] Preferably, the adding mechanism includes a storage tank fixedly installed at the upper end of the decolorizing tank, a feeding cylinder fixedly installed at the bottom of the storage tank, a spiral extrusion rod rotatably installed inside the feeding cylinder, and the end of the spiral extrusion rod fixedly installed on one end of a drive shaft, a feeding port fixedly installed at the bottom of the feeding cylinder, and the feeding port extending into the decolorizing tank, a positioning shaft fixedly installed at the top of the decolorizing tank, a rotating frame movably installed on the positioning shaft, a sealing end cap fixedly installed at the end of the rotating frame, a torsion spring sleeved on the positioning shaft, and a control screw threadedly installed on the decolorizing tank, with the control screw vertically aligned with the rotating frame.

[0010] Preferably, the rotating frame has a movable hole, and the rotating frame is movably mounted on the positioning shaft through the movable hole.

[0011] Preferably, the sealing end cap is movably installed below the feeding port via a rotating frame, one end of the torsion spring is fixedly installed on the rotating frame, the other end of the torsion spring is fixedly installed on the positioning shaft, bearings are provided at both ends of the feeding cylinder, and the spiral extrusion rod is rotatably installed inside the feeding cylinder via the bearings.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this application, after the drive motor starts, it drives the stirring shaft to rotate. Subsequently, the rotation of the stirring shaft causes the stirring blades to rotate within the decolorization tank, thereby achieving the stirring effect on the solution. At the same time, under the action of the helical gear transmission mechanism, the stirring shaft drives the transmission shaft to rotate, thereby controlling the addition mechanism to perform the addition operation.

[0014] In this application, with the electromagnetic clutch engaged, the drive shaft drives the screw extruder to rotate inside the feeding cylinder. This process simultaneously achieves stirring and the addition of decolorizing agent. Users can monitor the decolorization of the solution in real time through the observation window. Once the solution color is detected to be fading, the electromagnetic clutch can be quickly operated to separate, ensuring that feeding is stopped immediately when the solution reaches the expected decolorization effect. This effectively reduces the excessive use of decolorizing agent and lowers production costs. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a decolorizing device for pharmaceutical solutions, including a decolorizing tank 1, an observation window 2 fixedly installed on the decolorizing tank 1, a discharge port 3 fixedly installed at the bottom of the decolorizing tank 1, a feed port 4 at the top of the decolorizing tank 1, a stirring mechanism 5 on the decolorizing tank 1, and an adding mechanism 6 on one side of the drive motor 501. Through the combined use of the stirring mechanism 5 and the adding mechanism 6, a decolorizing agent can be added to the solution while stirring, and the addition can be stopped immediately when the solution decolorizes, reducing the waste of the decolorizing agent.

[0023] like Figure 2 and Figure 3As shown, the stirring mechanism 5 includes a drive motor 501 fixedly mounted on the decolorizing tank 1. A stirring shaft 506 is fixedly mounted on the output end of the drive motor 501. A stirring blade 507 is fixedly mounted on the stirring shaft 506. A transmission shaft 503 is rotatably mounted on one side of the stirring shaft 506. An electromagnetic clutch 504 is provided on the transmission shaft 503. Both the transmission shaft 503 and the stirring shaft 506 are provided with helical gears 505, and the two sets of helical gears 505 mesh together. A motor frame 502 is provided on the drive motor 501. The drive motor 501 is fixed on the decolorizing tank 1 through the motor frame 502. A retainer is provided inside the motor frame 502. The transmission shaft 503 is rotatably mounted on one side of the stirring shaft 506 through the retainer.

[0024] Specifically, when the drive motor 501 is started, it will drive the stirring shaft 506 to rotate. As the stirring shaft 506 rotates, the stirring blades 507 also rotate within the decolorization tank 1, effectively stirring the solution. Simultaneously, under the force of the helical gear 505, the stirring shaft 506 will further drive the transmission shaft 503 to rotate. The rotation of the transmission shaft 503 will control the adding mechanism 6 to begin its adding operation, ensuring smooth material addition throughout the entire stirring process.

[0025] like Figure 2 , Figure 4 and Figure 5 As shown, the adding mechanism 6 includes a storage tank 601 fixedly installed at the upper end of the decolorizing tank 1. A feeding cylinder 602 is fixedly installed at the bottom of the storage tank 601. A spiral extrusion rod 603 is rotatably installed inside the feeding cylinder 602, and the end of the spiral extrusion rod 603 is fixedly installed on one end of the drive shaft 503. A feeding port 604 is fixedly installed at the bottom of the feeding cylinder 602 and extends into the decolorizing tank 1. A positioning shaft 608 is fixedly installed at the top of the decolorizing tank 1. A rotating frame 607 is movably installed on the positioning shaft 608. A sealing end cap 605 is fixedly installed at the end of the rotating frame 607. A torsion spring 609 is sleeved on the positioning shaft 608. A control screw 606 is threadedly installed on the decolorizing tank 1, and the control screw 606 is vertically aligned with the rotating frame 607.

[0026] Specifically, when the electromagnetic clutch 504 is engaged, the drive shaft 503 begins to operate, driving the screw extruder 603 to rotate inside the feeding cylinder 602. This process is accompanied by a stirring action, and the screw extruder 603 evenly adds the decolorizing agent to the solution. The user can monitor the color change of the solution through the observation window 2. Once the solution color begins to fade, measures can be taken quickly by controlling the electromagnetic clutch 504 to achieve separation. This ensures that feeding stops immediately the moment the solution color fades, effectively avoiding excessive use of the decolorizing agent and reducing unnecessary costs. Furthermore, by rotating the control screw 606 upwards, the torsion spring 609 can be further activated, thereby driving the rotating frame 607 to rotate. As a result of this series of actions, the sealing end cap 605 covers the bottom of the feeding port 604, ensuring the cleanliness of the inside of the feeding cylinder 602 and preventing any possible foreign matter from entering.

[0027] Working principle: During use, the solution is injected into the decolorization tank 1 through the feed inlet 4. After the solution is injected into the decolorization tank 1, the drive motor 501 can be started. Starting the drive motor 501 will drive the stirring shaft 506 to rotate. The rotation of the stirring shaft 506 will then drive the stirring blades 507 to rotate within the decolorization tank 1, thereby stirring the solution. Simultaneously, under the action of the helical gear 505, the stirring shaft 506 will drive the transmission shaft 503 to rotate. When the transmission shaft 503 rotates, the electromagnetic clutch 504 can be engaged. When the electromagnetic clutch 504 is engaged, the transmission shaft 503 will drive the spiral extruder 603 to rotate within the feeding cylinder 602. While stirring, a decolorizing agent is added to the solution. The user can observe whether the solution has faded through the observation window 2. After the solution fades, the electromagnetic clutch 504 can be immediately disengaged, so that the feeding is stopped immediately when the solution fades, reducing the waste of decolorizing agent. After the feeding is stopped, the stirring blade 507 can be allowed to continue to rotate for a period of time, so that the decolorizing agent can fully absorb the pigment in the solution. Then, the control screw 606 can be rotated up and down. After the control screw 606 is rotated up, it will drive the torsion spring 609 to drive the rotating frame 607 to rotate, so that the sealing end cover 605 covers the bottom of the feeding port 604 to prevent foreign objects from entering the feeding barrel 602.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
